JP 2008-50784 A

  However, in the case of the above-described hanging structure in which the ceiling frame is hung on the horizontal member using the hanging bolt having the rod shaft structure and the mounting bracket having the hook structure and the hanger structure, first, the strength of the hanging bolt itself, the horizontal member and the hanging bolt are used. And the strength of the connection between the suspension bolts and the field support are low, and there is a disadvantage that the ceiling frame is lacking in earthquake resistance.

  For example, the excitation force at the time of the occurrence of an earthquake includes vertical and vertical vibrations due to pitching and horizontal vibrations due to rolling, and in reality, these vibrations are more complicatedly combined. Therefore, in addition to the vertical load, a horizontal load is applied to the hanging bolts and the upper and lower mounting brackets, and it is required that the suspension bolts and the upper and lower mounting brackets have sufficient seismic resistance against the loads in both directions.

  However, a hanging bolt with a single rod shaft structure or a mounting structure with a hook structure and a hanger structure cannot meet such a demand, and the hanging bolt portion is bent and the hook portion and the hanger portion are disengaged. There is a fear.

  Therefore, in the conventional configuration, it is necessary to install a brace material to cope with the above-mentioned roll, and to fix the hook portion and the hanger portion.

  The present invention has been made to solve such a problem, and the cross-sectional area is effectively enlarged by forming the ceiling frame hanging material from a predetermined cross-sectional shape, a shaped steel or a steel pipe having a predetermined outer diameter. In addition to improving the strength against vertical compressive / tensile loads, the rigidity in the direction perpendicular to the axis, and the strength in the horizontal direction, a ceiling frame suspended from a shaped steel or steel pipe having the predetermined cross-sectional shape and the predetermined outer diameter. By connecting the upper end of the material to the horizontal material for mounting the building side ceiling frame via the specified mounting bracket and connecting the lower end side to the ceiling frame, the strength and seismic resistance of the hanging part of the ceiling frame are greatly improved. It is an object of the present invention to provide a suspended ceiling frame structure.

  The ceiling frame suspension structure according to the present invention is provided with the following problem solving means in order to solve the above problems.

(1) First Problem-Solving Means First, in the ceiling-frame hanging structure according to the first problem-solving means of the present invention, a ceiling frame corresponding to the ceiling structure of the building is provided on a ceiling base side to which the ceiling frame is attached. A ceiling frame suspended structure in which a grid-like ceiling frame composed of a field edge and a field edge receiver is suspended from the horizontal material via a ceiling frame suspension material, The side horizontal member and the ceiling frame hanging material are each made of a shaped steel or a steel pipe having a predetermined cross-sectional shape and a predetermined outer diameter, and the upper end of the ceiling frame hanging material is horizontally fixed to the ceiling base side through a predetermined mounting bracket. The ceiling frame is connected to a lower end of the ceiling frame hanging member and connected and supported in a crossed state at the lower end of the ceiling frame hanging member.

  In the configuration of the means for solving the problems of the present invention, the ceiling base horizontal member of the building and the ceiling frame suspending member for suspending the ceiling frame with respect to the ceiling base horizontal material have a predetermined sectional shape and a predetermined outer diameter, respectively. It is composed of a shaped steel or steel pipe.

  Therefore, the rigidity and strength of the ceiling base horizontal member to which the ceiling frame suspending material is attached are increased, as well as the strength of the ceiling frame suspending material itself against the vertical compressive / tensile load and the rigidity in the direction perpendicular to the axis. The strength in the direction is greatly improved as compared with the conventional bolt shaft.

  For this reason, an upward wind pressure acts on the hanging portion of the ceiling frame, so that the ceiling frame hanging member can be configured as a wind-resistant ceiling corresponding to a case in which a compressive load is applied to the hanging member.

  In this case, for the ceiling base-side horizontal member, for example, a C-section steel is used as the section steel and a square steel pipe is used as the steel pipe. For the ceiling frame suspension material, for example, a lip channel steel, a channel steel, a square steel pipe as a steel pipe, and a circular steel pipe as necessary are used as the shape steel.

  In addition, in the same configuration, the ceiling base horizontal member is attached to the ceiling base horizontal member via a single mounting bracket integrally provided with a mounting portion attached to the ceiling base horizontal member and a mounting portion for mounting the ceiling frame hanging member. On the other hand, the ceiling frame hanging material is attached so as to cross in the vertical direction.

  As a result, the ceiling mounting-side horizontal member and the ceiling frame hanging member, each having high strength, are reliably positioned in the axial direction intersecting each other by the single mounting bracket, and are firmly connected.

  Therefore, by using the mounting bracket, it is not necessary to adjust the axial position of the hanging member of the ceiling frame with respect to the horizontal member on the ceiling ground side during the connecting operation, and the connecting strength of the connecting portion is also increased.

  As a result, the earthquake resistance of the hanging portion of the ceiling frame with respect to the horizontal material on the ceiling ground side at the time of the earthquake when the earthquake occurs is effectively improved. As a result, there is no need to install a brace material and fix the engaging portion as in the case of the conventional suspension bolt structure.

(2) Second Problem-Solving Means Next, the ceiling frame suspension structure in the second problem-solving means of the present invention is the same as the first problem solving means of the present invention, except that the upper end of the ceiling frame suspending member is provided. The predetermined mounting bracket attached to the ceiling base horizontal member in a state crossing the ceiling base horizontal member has a U-shaped cross-section in which a mounting portion attached to the ceiling base horizontal member is slidably fitted to the outer periphery of the ceiling base horizontal member. Attachment portions formed at the joint portion and for attaching the ceiling frame hanging material are provided at the upper and lower ends of the U-shaped cross-section fitting portion slidably fitted to the outer periphery of the horizontal material on the ceiling base side. It is characterized in that it is formed on a pair of upper and lower fitting portions into which the suspending member is slidably fitted.

  As described above, the upper end of the ceiling frame hanging member made of a shape steel or a steel pipe is attached to the ceiling base horizontal member of the mounting bracket that connects the upper end of the ceiling frame hanging member made of the same shape steel or the steel tube in a state of crossing the same. The mounting portion is formed in a fitting portion having a U-shaped cross section which is slidably fitted to the outer periphery of the ceiling base side horizontal member, and the mounting portion for mounting the ceiling frame suspending member is the ceiling base side horizontal member. Are formed on a pair of upper and lower fitting portions that are slidably fitted on the ceiling frame hanging material at upper and lower ends of a U-shaped fitting portion slidably fitted on the outer periphery of The following effects can be obtained.

  That is, first, a fitting portion having a U-shaped cross section of the mounting portion with respect to the ceiling base horizontal member is slidably fitted to the outer periphery of the ceiling base horizontal member, and is positioned and held in the horizontal direction.

  Next, in the same state, a pair of upper and lower members which are slidably fitted with the ceiling frame suspending material at the upper and lower ends of the fitting portion having a U-shaped cross section fitted to the outer periphery of the ceiling base side horizontal material. The hanging member of the ceiling frame is slidably fitted to the fitting portion of (1), and the height position in the vertical direction is adjusted.

  Finally, these parts are fastened and fixed to the corresponding horizontal member and ceiling frame hanging member using a screw member or the like.

  As a result, the ceiling frame hanging member is attached to the ceiling base horizontal member in a state of being firmly connected to and integrated with the ceiling base side horizontal member via the one high-strength mounting bracket.

  As described above, in this configuration, the mounting bracket is made of one metal member, and has a function of integrating and positioning the two members of the horizontal member and the ceiling frame hanging member.

  Therefore, as compared with the case of the suspension bolt structure already described, not only the suspension strength and the seismic strength are high, but also the mounting work becomes remarkably easy.

  In addition, in the case of the same configuration, the ceiling frame hanging member mounting portion, the fitting portion for slidably inserting the ceiling frame hanging material is a ceiling base side mounting portion, and the ceiling base side horizontal material Are provided on the upper and lower ends of a fitting portion having a U-shaped cross-section, which is slidably fitted to the pair, and two sets are provided at a predetermined distance.

Therefore, the positioning and the position fixing in the vertical direction can be surely performed, and more firmly fixed and attached at two places can be provided.
(3) Third Problem Solving Means Next, the ceiling frame hanging structure in the third problem solving means of the present invention is the same as the second problem solving means of the present invention, and the ceiling frame hanging member can be slid. And a pair of upper and lower fitting portions that fit into the ceiling base side horizontal member are integrally formed with a fitting portion having a U-shaped cross section that is slidably fitted to the outer periphery of the ceiling base side horizontal member.

In the case of such a configuration, three sets of fitting portions can be formed relatively easily by cutting a metal plate into a predetermined shape and bending the metal plate into a predetermined shape.
(4) Fourth Problem Solving Means Next, the ceiling frame hanging structure according to the fourth problem solving means of the present invention is the same as the second problem solving means of the present invention, except that the ceiling frame hanging member can be slid. The pair of upper and lower fitting portions that fit into the ceiling base side horizontal member are configured separately from the U-shaped cross-section fitting portion that is slidably fitted to the outer periphery of the ceiling base side horizontal member. It is characterized by being integrated by being welded to mounting edges provided on the upper and lower ends of a fitting portion having a U-shaped cross section which is slidably fitted to the fitting portion.

Like the ceiling frame hanging structure in the third problem solving means, a pair of upper and lower fitting portions for slidably fitting the ceiling frame hanging material is slidably fitted to the outer periphery of the ceiling base side horizontal material. When formed integrally with a fitting portion having a U-shaped cross section, it can be formed by cutting and bending a single metal plate, but the cut causes waste of the metal material, and Processing is complicated, manufacturing efficiency is low, and costs increase.

  Therefore, a pair of upper and lower fitting portions for slidably fitting the hanging member of the ceiling frame is formed separately from a fitting portion having a U-shaped cross section which is slidably fitted to the outer periphery of the horizontal material on the ceiling base side. On the other hand, mounting edges are provided at upper and lower ends of a U-shaped cross-section which is slidably fitted to the outer periphery of the horizontal material on the ceiling base side, and are welded to the mounting edges to be integrated. To do it.

  With such a configuration, a U-shaped cross-section fitting portion slidably fitted to the outer periphery of the ceiling base side horizontal member is formed in, for example, a hat-shaped cross section, and the edges at both ends are suspended from the ceiling frame. It can be a mounting edge of a pair of upper and lower fitting portions into which the material is slidably fitted.

  When a pair of upper and lower fitting portions for slidably fitting the hanging member of the ceiling frame with respect to these mounting edges are joined by welding to be integrated, the same configuration as the integrated one can be more easily achieved. Can be configured.

(5) Fifth Problem Solving Means Next, the ceiling frame hanging structure in the fifth problem solving means of the present invention is the same as the second, third or fourth problem solving means of the present invention, except that the mounting bracket A pair of upper and lower fitting portions for slidably fitting the ceiling frame hanging member are formed in a short cylindrical body having a rectangular C-shaped cross section.

  In the case of such a configuration, the ceiling frame suspending member is securely slidably inserted into the short cylindrical body having a rectangular C-shaped cross section, and is reliably held in the same state. Therefore, the sliding operation of the hanging member of the ceiling frame and the adjustment of the height position in the vertical direction are significantly facilitated. Further, the holding force after the attachment is increased.

  In this case, the short cylindrical body having a rectangular C-shaped cross section for fitting the ceiling frame suspending member is, of course, in the case of an integrated structure as in the third means for solving the above-mentioned problems, the closed cross-section side rear wall portion thereof Are integrally connected to a fitting portion having a U-shaped cross section which is slidably fitted to the outer periphery of the horizontal material on the ceiling base side.

  However, in the case of the separate structure as in the fourth means for solving the above problem, the closed section side rear wall portion is slidably fitted to the outer periphery of the ceiling base side horizontal member, and has a U-shaped cross section. In addition to the configuration of welding and integrating with the mounting edge of the U-shaped, on the contrary, a pair of bent rib portions on the open cross section side are welded and bonded to the mounting edge of the U-shaped fitting part An integrated configuration is also employed. In the case of the latter configuration, the short cylindrical body having a rectangular C-shaped cross section for inserting the ceiling frame suspending material is substantially a rectangular cylindrical body having a closed sectional structure, and is connected to the ceiling frame suspending material in the fitted state. Strength is improved.

(6) Sixth Problem-Solving Means Next, the ceiling frame suspension structure in the sixth problem-solving means of the present invention is the same as the structure of the second, third or fourth problem-solving means of the present invention, except that the mounting bracket A pair of upper and lower fitting portions for slidably fitting the hanging member of the ceiling frame is formed in a short cylindrical body having a rectangular cross section.

  The pair of upper and lower fitting portions for slidably fitting the hanging member of the ceiling frame of the mounting bracket are not limited to the short cylindrical body having a square C-shaped cross section, but the lengths of the bent ribs are increased to abut each other. Alternatively, it may be configured as a short cylinder having a square cross section having a closed cross section as a whole.

In such a case, the short cylindrical body having a rectangular cross section for inserting the ceiling frame suspending member is, of course, in the case of an integral structure as in the third means for solving the above-mentioned problem, the closed body is closed. The rear wall portion on the cross-section side is formed integrally with a fitting portion having a U-shaped cross-section which is slidably fitted on the outer periphery of the horizontal material on the ceiling base side.
On the other hand, in the case of the separate structure as in the fourth means for solving the problem, the closed section side rear wall portion is slidably fitted to the outer periphery of the ceiling base side horizontal member so as to have a U-shaped cross section. In the opposite configuration, a pair of left and right bent rib parts that are butted against each other are welded and joined to the mounting edge of the U-shaped fitting part. Any one of the configurations to be used is adopted.
In the case of the latter configuration, the rectangular cylinder with a rectangular cross section for inserting the ceiling frame hanging material becomes a rectangular cylinder with a completely closed cross-sectional structure, and is welded to the mounting edge of the U-shaped fitting section The area is enlarged, the mounting strength is improved, and the connection strength with the ceiling frame hanging material in the fitted state is further improved.
(7) Seventh Problem Solving Means Next, the ceiling frame hanging structure in the seventh problem solving means of the present invention is the ceiling frame hanging structure according to the first, second, third, fourth, fifth or sixth aspect of the present invention. In the configuration of the problem solving means, the connecting bracket for connecting and supporting the ceiling frame at the lower end of the ceiling frame hanging material has an adjusting function of the height position for connecting and supporting the ceiling frame, and the height position for connecting and supporting the ceiling frame. It is characterized in that the ceiling frame is connected after being adjusted.
As in the configuration of the first, second, third, fourth, fifth, or sixth problem solving means of the present invention, a ceiling frame hanging member whose upper end is attached to a ceiling base horizontal member is provided. Conventionally, when the ceiling frame is attached to the lower end, conventionally, the field support portion supporting the field edge of the ceiling frame including the field edge and the field edge support is aligned in a cross state with the lower end where the ceiling frame hanging material is to be attached. The direct connection method of screwing and fastening with a drill screw was adopted.

  However, the ridge receiving portion that supports the ridge of the ceiling frame including the ridge and the ridge receiver is easily bent by the load and is not always maintained in a horizontal state. Therefore, the positioning itself is not always easy. In addition, screwing of the drill screw must be performed after the operator has maintained the crossed state (overlapping state) where the positioning has been performed, and the positional deviation is caused by the rotational force and vibration at the time of screwing the drill screw. There are problems that can easily arise. Furthermore, it is not possible to say that the supporting strength of the load at the connecting portion is sufficient simply by directly connecting the edge support to the lower end portion of the ceiling frame hanging material with a drill screw.

  Therefore, in the means for solving the problems of the present invention, the ceiling frame (field support) is connected to the lower end of the ceiling frame hanging material via a high-strength connection metal, and the connection metal is connected to the ceiling frame. It is configured so as to have a position adjusting function, so that the ceiling frame can be connected and supported after adjusting the vertical position of the ceiling frame to be attached.

  By doing so, the connection strength is improved, the supporting strength of the ceiling frame by the ceiling frame hanging material is improved, and the mounting position of the ceiling frame with respect to the ceiling frame hanging material can be adjusted. Even if the receiver is bent, it is possible to always adjust the height to the correct position before mounting.

(8) Eighth Problem Solving Means Next, the ceiling frame hanging structure in the eighth problem solving means of the present invention is the same as the structure of the seventh problem solving means of the present invention, except that the lower end of the ceiling frame hanging member is provided. A connection fitting connected to the ceiling frame is slidably fitted to the first fitting fixed to the lower end of the ceiling frame hanging material and the lower end of the ceiling frame hanging material via the first fitting in a vertical direction. The second metal fitting is provided with a connecting bolt which is slidably held in a vertical direction through a height hole for adjusting a height position provided in the first metal fitting. It is characterized in that it is connected to an arbitrary height position of the first metal fitting so as to connect and support the ceiling frame at an arbitrary height position of the first metal fitting.

  In the configuration of the means for solving the problems of the present invention, a connection position adjusting function for connecting and supporting the ceiling frame according to claim 7 is provided, and a connection for connecting and supporting the ceiling frame after adjusting a height position of the ceiling frame in the vertical direction. A first metal fitting that is positioned and fixed to a lower end of the ceiling frame hanging material, and a second metal fitting that is vertically slidably fitted to the lower end of the ceiling frame hanging material via the first metal fitting. The second fitting is provided with an arbitrary part of the first fitting via a connection bolt which is slidably held in a vertical direction through an elongated hole for adjusting a height position provided in the first fitting. It is designed to be connected to the height position, and at an arbitrary height position of the connected first metal fitting, it is finally fixed to the lower end of the ceiling frame hanging material with a drill screw or the like to connect the ceiling frame. I have come to support it.

  Therefore, according to such a configuration, first, the first metal fitting is positioned at the lower end portion of the ceiling frame hanging material and then fixed, and the top metal frame is attached to the ceiling frame hanging material via the first metal fitting. When the second metal fitting for fitting is fitted, the second metal fitting for ceiling frame mounting is provided via a connection bolt supported slidably in the vertical direction through a long hole having a predetermined length in the vertical direction. The first metal fitting can be connected in a vertically slidable manner. Therefore, in the same state, the height of the second metal fitting for mounting the ceiling frame is adjusted to set an accurate mounting position.

  Then, if the top frame (its field edge receiving portion) is fitted to the top frame fitting portion of the second fitting for mounting the top frame, the top frame is finally mounted at an appropriate position. it can.

  In this case, the height adjustment span of the ceiling frame mounting position with respect to the ceiling frame hanging member is determined by the vertical length of the elongated hole of the first metal fitting supporting the connection bolt. The connecting bolt performs a temporary fixing function of the second metal fitting for the ceiling frame to the first metal fitting at the time of height adjustment, but the second mounting metal fitting for the ceiling frame becomes the second metal fitting when the height adjustment is completed. It has a function of fixing to the ceiling frame hanging material via the first bracket.

(9) Ninth Problem Solving Means Next, a ceiling frame suspension structure according to a ninth problem solving means of the present invention is the same as the structure of the eighth problem solving means of the present invention. A fitting claw to be fitted to the frame hanging material is provided.

  According to such a configuration, when the first metal fitting is fixed to the ceiling frame hanging material, the first metal fitting can be temporarily fixed in a state where the first metal fitting is securely positioned on the ceiling frame hanging material. Even if it is not supported by hand, it is securely held in the positioning state, and even if the drill screw is screwed, it can be accurately fixed without displacement.

Therefore, the workability when fixing the first metal fitting to the ceiling frame hanging material is improved, and of course, the ceiling metal hanging material via the first metal fitting of the second metal fitting for fixing the ceiling frame is fixed. The mounting position of the ceiling frame is easily adjusted, and the mounting accuracy of the ceiling frame to the ceiling frame hanging member is also improved.
(10) Tenth problem solving means
Next, in the structure of the ninth problem solving means of the present invention, the ceiling frame hanging structure in the tenth problem solving means of the present invention is fitted to the ceiling frame hanging material of the first fitting. The fitting claw is located on both sides of the upper end of the first metal fitting and is fitted on the left and right sides of the ceiling frame suspending member. It is characterized in that it comprises a second fitting claw that is brought into contact with the left and right ends of the lower end portion of the first bracket mounting surface of the ceiling frame hanging member.

According to such a configuration, when the first metal fitting is fixed to the lower end of the ceiling frame hanging material, the second fitting claw on the lower end portion end surface of the first metal fitting is fixed to the first frame hanging material of the ceiling frame hanging material. By abuttingly engaging the lower end of the metal fitting mounting surface, the mounting position in the vertical direction is determined, and the first fitting claws on both sides of the upper end of the first metal fitting are placed on both sides of the ceiling frame hanging member. By fitting, the mounting position in the left-right direction can be determined, and the whole can be temporarily fixed securely. That is, according to the configuration, the upper, lower, left, and right mounting positions can be accurately positioned, temporarily fixed securely, and then fixed with a drill screw.

As a result, even if the operator does not support it by hand, the positioning state is reliably maintained, and even if the drill screw is screwed, it can be accurately fixed without any displacement.

Therefore, the workability when fixing the first metal fitting to the ceiling frame hanging material is improved, and of course, the ceiling metal hanging material via the first metal fitting of the second metal fitting for fixing the ceiling frame is fixed. The mounting position of the ceiling frame is easily adjusted, and the mounting accuracy of the ceiling frame to the ceiling frame hanging member is also improved.

In this case, the second fitting claws, which are on the left and right sides of the lower end portion of the first metal fitting and are in contact with the left and right sides of the lower end portion of the first metal fitting mounting surface of the ceiling frame hanging material, are simply claws. A part of the lower end portion of the main body may be bent at 90 degrees, or the tip of the 90-degree bent piece may be bent at 90 degrees to form a cono-shape, leaving a predetermined gap. It may be configured to engage with the back side of the mounting surface of the section.

  As a result, according to the present invention, in addition to the strength and rigidity of each of the ceiling frame hanging material and the ceiling base horizontal member, the bonding strength between the ceiling frame hanging member attachment portion and the ceiling base horizontal member is greatly improved. In addition, the strength of the entire hanging portion of the ceiling frame is greatly improved.

  As a result, the earthquake resistance of the entire ceiling base is also improved, and it is possible to provide a ceiling frame hanging structure with higher earthquake resistance.

  The mounting bracket for attaching the ceiling frame hanging member to the horizontal member has a mounting portion for attaching each of the horizontal member and the ceiling frame hanging member while being a structurally single metal member. It is supported in a predetermined state by slidably fitting to a corresponding part, and after being appropriately positioned, it can be easily attached using a screw member or the like.

  For this reason, the work of attaching the hanging member of the ceiling frame to the horizontal member is significantly facilitated.

The lattice-shaped ceiling frame composed of the field support 6 is suspended in a stable state with good seismic resistance (the ceiling frame suspension structure for the horizontal reinforcing members 3, 3,..., 3, 3,...). Will be described later in detail).

  In the configuration of FIG. 13, the ceiling base portions above the vertical members (reinforcement hanging members) 70, 70... Of the ceiling base in FIG. 1 are omitted, and the horizontal reinforcing members in the XY directions are omitted. 3, 3,... Also omit the horizontal reinforcing members 3, 3,... In the X direction, and show only the horizontal reinforcing members 3, 3,.

  The length of the vertical material (reinforcement suspending material) 70,70..of the base part of the ceiling base which suspends and supports the horizontal reinforcing members 3,3 ,. The brace members 80 are formed in a size corresponding to the depth of the ceiling of the building, for example, and bracing members 80, 80,... , And the horizontal reinforcing members 3, 3,... In the XY directions are configured to have sufficiently high seismic strength against rolling.

  For the purpose of improving the seismic strength, various types of rectangular steel pipes for the vertical members 70 are conceivable. In this embodiment, for example, as shown in FIG. A thick metal plate is bent into a square or rectangular cross section, and its side edges 70a and 70b are connected to each other at a corner A on one side A so that they are joined together in an S-shape. The tying portion is fixed by providing a bending rib 70c inside the portion, and a rectangular tube-shaped one is adopted. The same applies to a square steel pipe for the horizontal reinforcing member 3 and a square steel pipe for the brace material 80.

  Further, a rectangular cup-shaped reinforcing metal member 90A is provided at one of the upper and lower ends (or both ends) of the vertical members 70, 70, as required (see FIGS. 9 to 10).

(About the mounting structure of the vertical members 70, 70... For the mounting edges 60a, 60a... Of the upper H-shaped steel members 60, 60...)
The upper ends of the vertical members 70, 70 .. are attached to the mounting edges 60a, 60a .. of the H-shaped steel members 60, 60 .., for example, as shown in FIGS. It is firmly attached by using an auxiliary metal fitting 61 and an auxiliary metal fitting 64.

  The vertical material mounting bracket 61 has a bottom wall surface (abutment seating surface) 610 which is abutted in a stable sitting state corresponding to the cross-sectional area and the cross-sectional shape of the upper end portion of the vertical material 70 made of the rectangular steel pipe having a rectangular cross section. A mounting box main body 61a having a rectangular box shape (a rectangular parallelepiped shape in which the entire front side is opened forward in the horizontal direction in a U shape), and a front side of the mounting body 61a (on the mounting edge 60a side of the H-shaped steel 60). ) Are provided in the front-rear direction with a predetermined depth in the front-rear direction, and have a U-shaped cross-section, and are provided on the upper wall surface 611 side of the front-rear central part of the connection ports 61b, 61b and provided from the upper side to the lower side. And a fastening bolt 61c which is inserted and screwed from the upper side to the lower side at the time of mounting, and fixes the mounting bracket main body 61a to the mounting edge 60a of the H-shaped steel 60 from above. That.

  The fastening bolt 61c is adapted to be screwed into a fastening bolt screw hole via, for example, a spring washer 61j and a locking nut 61h.

  The fitting openings 61b, 61b are formed by cutting the left and right side walls 612, 612 on the front side opening of the mounting bracket main body 61a rearward to a predetermined depth. In the case of this embodiment, the fitting ports 61b, 61b are provided in the front half portion in the front-rear direction when viewed from the side surface of the mounting member main body 61a.

  On the other hand, substantially the entire bottom wall 610 abuts against the upper end of the vertical member 70, and in this abutting state, the vertical member is connected to the vertical member 70 by bolts 63a via a pair of connecting brackets 62a provided on both left and right sides of the bottom. The upper ends 70, 70... Are firmly connected and integrated.

    In the case of such a configuration, the vertical members 70, 70,... Are formed of rectangular steel pipes having a rectangular cross section, and the vertical member mounting bracket 61 is also formed in a rectangular box shape. Are integrally connected to the rectangular material structure. And it is firmly attached to the attachment edge 10a of the H-section steel 10 via the upper end side vertical material attachment fitting 61.

  That is, when suspending the vertical members 70, 70,..., The fitting holes 61b, 61b having the U-shaped cross section of the rectangular box-shaped vertical member main body 61a as shown in FIGS. The fastening bolt 61c is fitted into the mounting edge portion 60a on the near side of the section steel 60, and the fastening bolt 61c is inserted and screwed downward in the orthogonal direction. The upper side of the fitting holes 61b, 61b and the lower surface of the mounting edge 60a of the H-shaped steel 60 are joined together through the front end of the fastening bolt 61c, thereby fastening and integrating them together. Secured with a square area.

  As described above, the vertical mounting bracket main body 61a has a box-shaped configuration having a predetermined width in the front-rear and left-right directions, and has U-shaped fitting openings 61b, 61b having a predetermined depth on both sides thereof. By being fitted and fixed (joined and fixed) to the mounting edge 60a of the H-shaped steel 60, compared with the conventional hook structure and the hanging structure with the rod shaft, The joint surface of the mounting portion is much wider, the deformation rigidity of the vertical members 70 in the direction perpendicular to the axis is increased, and the supporting force against the vertical load is also much larger.

  In addition, in the case of this embodiment, in addition to the above-described configuration, an auxiliary metal fitting 64 having a substantially similar structure is provided on the other-side mounting edge 60a of the corresponding H-shaped steel 60.

  As shown in FIGS. 3 and 12, this auxiliary metal fitting 64 also has a rectangular box-shaped (rectangular parallelepiped opening on the entire front side) auxiliary metal body 64a and a front side of the rectangular box-shaped auxiliary metal body 64a ( Fitting ports 64b, 64b having a predetermined depth in the front-rear direction opened at the mounting edge 60a side of the H-shaped steel 60) and central portions in the front-rear direction of the fitting ports 64b, 64b having the U-shaped cross section. It is provided on the upper wall surface from the upper side to the lower side, and is inserted and screwed from the upper side to the lower side at the time of mounting, and the rectangular box-shaped auxiliary bracket main body 64a is attached to the other side of the H-shaped steel 60. And a fastening bolt 64c fixed to the mounting edge 60a. The fitting holes 64b, 64b having a U-shaped cross section are provided on the left and right side walls on the front side opening of the auxiliary metal fitting body 64a. Notch at a predetermined depth It is formed Te.

  In the state where the fitting holes 61b, 61b and 64b, 64b face each other in the same horizontal plane direction, the vertical material mounting bracket 61 and the auxiliary metal fitting 64 are connected to each other by two left and right connecting rods 66, 66. The connection is made firmly in a tensile state.

  That is, in the actual mounting state, the auxiliary metal fitting 64 is also fitted and fixed to the mounting edge 60a at the other end of the H-shaped steel 60 in the same manner as the vertical member mounting metal fitting 61, and then the two are mutually connected. Are connected and fixed (pull-fixed) by the connecting rods 66, 66.

  Therefore, in the connection and fixed state of FIGS. 3 and 12, the vertical members 70, 70,... Suspending the horizontal reinforcing members 3, 3,. Are securely pulled and fixed in the fitting direction by the auxiliary metal fittings 64, so that even if an external force acts on the vertical material mounting metal fitting 61 in the non-fitting direction, the vertical metal fittings 61 do not come off, and the H-shaped steel Since the fitting edges 60a, 60a are fitted and fixed in opposite directions at two places on both ends, the fitting state itself is further strengthened.

  For example, in the case of the same configuration, as shown in FIG. 12, if a horizontal force in the direction of the arrow A1 acts on the vertical members 70, 70,... A pressing force in the direction of arrow A2 acts on the mounting edge 60a of the H-shaped steel 60, and a tensile force in the direction of arrow A3 acts on the connecting rods 66, 66.

  However, the mounting edge 60a of the H-section steel 60 has a high supporting rigidity and does not move, so that a large tensile force A3 acts on the connecting rods 66, 66. Therefore, if the auxiliary metal fittings 64 are not provided and the connecting rods 66, 66 are not provided, the fitting state of the fitting portion of the vertical material mounting fitting 61 may be deteriorated, and the fitting state may be removed depending on the case. .

  However, as described above, the two fittings, the vertical mounting bracket 61 and the auxiliary bracket 64, are used to fit and fix them at two places, and furthermore, they are placed at a predetermined width on the left and right and are connected to the two connecting rods 66. , 66, the auxiliary fitting 64 and the connecting rods 66, 66 reliably prevent deformation of the fitting portion due to the large tensile force A3, so that a more secure fitting state can be maintained. Become. As a result, the movement of the vertical members 70 in the A1 direction is also suppressed.

  On the other hand, assuming that a horizontal force in the direction of arrow B1 acts on the vertical members 70, 70,..., On the other hand, the H-shaped steel 60 A pulling force acts in the direction of arrow B2 on the mounting edge 60a, and a pressing force acts in the direction of arrow B3 on the connecting rods 66, 66.

  However, the mounting edge portion 60a of the H-section steel 60 has a high supporting rigidity and does not move, and a large pressing force B3 acts on the connecting rods 66, 66. Therefore, if the auxiliary metal fittings 64 and the connecting rods 66, 66 are not provided, the fitting state of the fitting portion of the vertical metal fitting 61 may be deteriorated, and the fitting state may be removed depending on the case. .

  However, as described above, the two fittings, the vertical mounting bracket 61 and the auxiliary bracket 64, are used to fit and fix them at two places, and furthermore, they are placed at a predetermined width on the left and right and are connected to the two connecting rods 66. , 66, the large pressing force B3 is blocked by the connecting rods 66, 66 and the auxiliary metal fitting 64, so that the deformation of the fitting portion due to the pressing force B3 is prevented, and a reliable fitting state is achieved. Can be maintained. As a result, the movement of the vertical member 70 in the B1 direction is also suppressed.

  As a result, the plurality of vertical members 70, 70,... Are less likely to sway, and the seismic resistance of the ceiling foundation side (horizontal reinforcing members 3, 3,. Greatly improved.

  The third fitting portion 113 to which the first and second fitting portions 111 and 112 are welded and integrated has, for example, as shown in FIG. It is constituted by a hat-shaped metal plate having a corresponding U-shaped portion and a pair of mounting edges (welding edges) 113d and 113e extending vertically in the upper and lower ends on the opening side of the U-shaped portion. I have. Then, the pair of upper and lower mounting edges 113d and 113e are respectively opposed to the rear side (closed) of the first and second fitting portions 111 and 112, each of which is a metal cylinder having a rectangular C-shaped cross section and formed independently. (Cross section side) The main body walls 111a and 112a are welded to be integrally held as shown in FIG. The first body is located at the top and bottom of the back side main body wall (vertical wall) except for the opening surface, at the center of upper and lower walls (horizontal walls) 113a and 113b, and at the center of mounting edges (welding edges) 113d and 113e. , Through which the same drill screws (or tapping screws) 12, 12,... As in the case of the second fitting portions 111, 112 are inserted. It is provided. The insertion holes (screw holes) 113c, 113c at the center of the mounting edges (weld edges) 113d, 113e are on the back side of the first and second fitting portions 111, 112 in the state of being integrated by welding. (Closed section side) It communicates coaxially with insertion holes (screw holes) 111c, 111c at the center of the main body walls 111a, 112a (see FIGS. 36 and 37).

  Then, as shown in FIGS. 32 to 34, the horizontal reinforcing member 3 to be attached is fitted in the third fitting portion 113 in a horizontally slidable manner (in the Y direction). After the alignment in the (Y direction) is performed, the drill screws (or tapping screws) 12, 12 are inserted and screwed together and fixed as in the case of the first and second fitting portions 111, 112. .

As a result, the connection structure can be securely and firmly attached, and it is difficult to move in the horizontal direction and the vertical direction.

  On the other hand, a field edge receiver 6 on the ceiling frame side is attached to the lower end portion 10b of the ceiling frame hanging member 10 thus firmly attached to the Y-direction reinforcement member 3 in the same manner as in the above embodiments. It is attached.

  Even with such a configuration, it is possible to realize a ceiling frame mounting structure having high earthquake resistance similar to the case of each of the above embodiments.

  Moreover, in the configuration of this embodiment, each of the first, second, and third fitting portions 111, 112, and 113 is a single metal member, as in the mounting bracket 11 of the first to ninth embodiments. The first and second fitting portions 111 and 112 are not formed integrally with each other, but are formed of the same metal member, but are formed separately from the third fitting portion 113, respectively. The non-opening side rear walls 111a, 112a are attached to mounting edge portions (joining edge portions) 113d, 113e extending vertically in the upper and lower ends of the opening surface side of the third fitting portion 113. It is integrally formed by polymerizing and welding.

  In such a case, any surface may be welded, so that the welding operation is facilitated.

<About the suspension structure of the ceiling frame according to Embodiment 13 of the present invention: see FIGS. 47 to 54>
Next, FIGS. 47 to 54 show a hanging structure of a ceiling frame according to Embodiment 13 of the present invention.

  The structure of this embodiment adopts the same lip channel steel as that of the second embodiment as the horizontal reinforcing member 3 in the X direction in the above-described ceiling frame mounting structure, as shown in FIGS. The ceiling frame suspension member 10 made of square steel described above is attached to the ribs 3a, 3a on the opening side using the mounting hardware 11 (see FIGS. 44 to 46) having the configuration of the twelfth embodiment. The upper end 10a is attached, and the lower end 10b of the ceiling frame hanging material 10 is connected to the lower end 10b of the ceiling frame using connecting metal fittings 14 and 15 having a function of adjusting the height of the ceiling frame. 6 is attached.

  The mounting structure of the upper end portion 10a of the ceiling frame hanging member 10 using the mounting bracket 11 with respect to the horizontal reinforcing member 3 is the same as that of the above-described twelfth embodiment. Thus, the description thereof will be omitted. In addition, the connection structure of the ceiling frame side ridge 7 with the ridge receiver 6 is the same as that in each of the above-described embodiments, and the description of the same components will be omitted by assigning the same reference numerals. .

  In this embodiment, the connection fittings 14 and 15 having the function of adjusting the mounting height of the ceiling frame are mounted on the front surface of the lower end portion 10b of the ceiling frame hanging member 10 (on the side opposite to the surface mounted on the field edge receiver 6). Surface), and a second fitting attached to the lower end portion 10b of the ceiling frame hanging member 10 and the field edge receiver 6 via the first fitting 14. A fitting (second connecting fitting unit) 15 and a connecting bolt 16 for connecting the second fitting 15 to the first fitting 14 in a height-adjustable state in which the second fitting 15 can be moved up and down and a fixed state in which the second fitting 15 cannot be moved up and down. Drill screws 12, 12 for screwing the first metal fitting 14 to the lower end 10b of the ceiling frame hanging material 10, and screwing the second metal fitting 15 to the lower end 10b of the ceiling frame hanging material 10. Drill screw 1 for fixing , And 12, are made of drill screws 12, 12 Metropolitan screwing fixing the second bracket 15 on the celestial frame side field edge receiving 6.

  The first metal fitting 14 has a vertically elongated groove-shaped bolt mounting portion 14a, a vertically extending elongated hole (slot) 14c formed at the center of the bolt mounting portion 14a, and both sides of the bolt mounting portion 14a. Metal having a hat-shaped cross section as a whole, including flange-shaped fixing portions 14c, 14c formed integrally with the metal member, and drill screw insertion holes 14d, 14d provided at the center of the flange-shaped fixing portions 14c, 14c. It consists of a board.

  In the first metal fitting 14, first, a bolt shaft portion protrudes toward the near side from the elongated hole 14b with respect to the groove-shaped bolt mounting portion (groove having a U-shaped cross section), and a head portion is formed in the groove. The connecting bolt 16 is mounted and supported in a state where it fits in the. Next, in a state where the connecting bolt 16 is supported, the flange-shaped fixing portions 14c and 14c are aligned with respect to the front surface (mounting surface) of the lower end portion 10b of the ceiling frame hanging member 10 (up and down and left and right). Then, the drill screws 12, 12 are screwed into the lower end portion 10b of the ceiling frame suspending material 10 through the drill screw insertion holes 14d, 14d to thereby form the ceiling frame suspending material 10. Is securely fixed and attached to the front surface of the lower end portion 10b.

  In this case, the positioning of the flange-shaped fixing portions 14c, 14c with respect to the front surface (mounting surface) of the lower end portion 10b of the ceiling frame hanging member 10 is performed by connecting the lower end surface of the first metal fitting 14 to the ceiling frame hanging member. 10 and both sides of the flange-shaped fixing portions 14c, 14c are matched with both sides of the ceiling frame hanging member 10. That is, the left-right width of the first metal fitting 14 is formed to be equal to the left-right width of the ceiling frame hanging member 10.

  The groove of the bolt mounting portion 14a is formed slightly deeper than the thickness of the bolt head of the connection bolt 16, and the groove of the first metal fitting 14 with respect to the lower end 10b of the ceiling frame suspending member 10 is formed. In the fixed state, the bolt 16 itself can be slid up and down via the bolt shaft. This is the same for the relationship between the width of the elongated hole 14b and the diameter of the bolt shaft.

  On the other hand, the second metal fitting 15 is made of a metal plate as a whole, and has a first fitting portion 15a for the top frame hanging member 10 having a U-shape in plan view and a U-shaped base of the first fitting portion 15a. A second slot (slot) 15b formed in the end face, drill screw insertion holes 15c, 15c formed in the center of the left and right side walls of the first fitting portion 15a, and drill screw insertion holes 15c, 15c. Drill screws 12, 12 inserted into the first fitting portion 15c and a top-shaped U-shaped top view frame (a field support 6 thereof) integrally provided outside the front end portions of the left and right side walls of the first fitting portion 15a. ), The drill screw insertion holes 15c, 15c formed in the center of the base end face of the U-shaped portion of the second engagement portions 15d, 15d, and the drill screw insertion holes 15c, 15c. It consists of drill screws 12 and 12 inserted through 15c . The first fitting portion 15a having a U-shape in plan view is fitted to the lower end 10b of the ceiling frame hanging member 10 made of the rectangular steel tube, and a second fitting having a U-shape in side view. The mating portions 15d, 15d are adapted to be fitted to the field edge receiver 6 of the ceiling frame made of the channel steel.

  When the first fitting portion 15a of the second fitting 15 is fitted to the lower end portion 10b of the ceiling frame hanging member 10 made of the rectangular steel tube, the first fitting 14 and the first fitting 14 are fitted. Are connected via connecting bolts 16 mounted on the bolt mounting portions 14a, and after the connection, they are connected by the connecting bolts 16 and finally fastened and fixed via washers 16a and nuts 16b. Until the first bracket 14 slides freely through the first long hole 14b of the first bracket 14 and the second long hole 15b of the second bracket 15, it is adjusted to a predetermined height position. It is possible to do.

  That is, as described above, the depth of the groove of the bolt mounting portion 14 a of the first metal fitting 14 is formed slightly deeper than the thickness of the bolt head of the connection bolt 16, and Even in a state where the ceiling frame hanging member 10 is fixed to the lower end portion 10b, the connection bolt 16 itself can be vertically slid using a bolt shaft in accordance with the length of the long hole 14b in the vertical direction. In this respect, the relationship between the width of the elongated hole 14b and the diameter of the bolt shaft is the same, and the bolt shaft of the connecting bolt 16 is loosely fitted with a gap slidable left and right. Can be slid up and down.

  Then, the first fitting portion 15a of the second metal fitting 15 for attaching the lower end portion 10b of the ceiling frame hanging member 10 to the field edge receiver 6 is fitted to the lower end portion 10b of the ceiling frame hanging member 10 during the attachment. When they are combined, they are first supported by the first metal fitting 14 fixed to the lower end 10b of the ceiling frame hanging material 10 and held in a state of being slidable in the vertical direction as described above. The bolt shaft at the tip end of the connecting bolt 16 (the bolt shaft portion protruding from the elongated hole 14b) penetrates the second elongated hole 15b in the base end surface of the U-shaped portion, and at the projected end side of the second elongated hole 15b. The nut 16c is fastened and fixed by screwing a nut 16c through a washer 16b having a diameter larger than the diameter of the second elongated hole 15b. In this case, the lengths of the left and right side walls of the first fitting portion 15a of the second fitting 15 are naturally determined in consideration of the height of the bolt mounting portion 14a of the first fitting 14 described above. The two fitting portions 15d, 15d are formed to have a length that can be accurately fitted to the field edge receiver 6. Further, the relationship between the length of the first elongated hole 14b on the side of the first fitting 14 and the length of the second elongated hole 15b on the side of the second fitting 15 is such that the length of the first elongated hole 14b is longer. The length of the second elongated hole 15b is formed to be as short as about twice the diameter of the bolt shaft of the connecting bolt 16. Basically, when the ceiling frame is attached to the ceiling frame hanging material 10 (when the ridge holder 6 is attached), the height adjustment is performed in the first elongated hole 14b, but only in the first elongated hole 14b. This is because, when the adjustment dimension is insufficient, the adjustment dimension is supplemented, or when the final fixing is performed, the fine level adjustment by operating only the second mounting bracket 15 is performed using the second elongated hole 15b.

  According to such a configuration, for example, the lower end portion 10b of the vertical ceiling frame suspending member (square steel pipe) 10 which is firmly attached to the horizontal reinforcing member 3 as the ceiling frame attaching member via the attachment fitting 11 is attached. When the ceiling frame is attached, the first metal fitting 15 is moved up and down with respect to the first metal fitting 14 (that is, the ceiling frame hanging material 10) via the connecting bolt 16 as follows, thereby obtaining the first metal fitting. After adjusting the mounting height using the length of the long hole 14b (and the second long hole 15b), it is finally fixed to the lower end portion 10b of the ceiling frame suspending member 10, and The second metal fitting 15 for fitting and fixing the ridge receiver 6 can be accurately mounted at an appropriate mounting height position. As a result, even if there is a deflection or the like due to the load on the field margin receiver of the ceiling frame, it is possible to perform horizontal mounting with the deflection corrected.

  In this embodiment, the ceiling frame is attached to the ceiling frame hanging member 10 by, for example, as shown in FIG. 47, the end of the lower end 10b of the ceiling frame hanging member 10 as an attachment position (reference line). First, the first fitting 14 of the connecting fitting unit is accurately attached to the same end.

  The attachment of the first metal fitting 14 to the end of the lower end 10 b of the ceiling frame hanging material 10 is performed, for example, by matching the lower end line of the first metal fitting 14 with the lower end surface line of the lower end 10 b of the ceiling frame hanging material 10. At the same time, with the left and right flange-shaped fixing portions 14c, the lines on both side surfaces of the fixing portions 14c are aligned with the lines on both right and left side surfaces of the ceiling frame hanging member 10, the drill screws 12, 14 are inserted through the drill screw insertion holes 14d, 14d. 12 is screwed into the lower end portion 10b of the ceiling frame hanging member 10. When the lower end surface and the left and right side lines of the first metal fitting 14 are attached in such a manner as to match the lower end surface line and the left and right side line of the lower end portion 10b of the ceiling frame hanging member 10 in this manner, basically, the first The entire metal fitting 14 is coaxially attached to the lower end 10b of the ceiling frame hanging member 10, and the first elongated hole 14 also extends in the vertical direction coaxial with the lower end 10b of the ceiling frame hanging member 10. become.

If the mounting position of the ceiling frame at that time is too low in a state in which the connection bolt 16 is not screwed to the lower end portion 10b), for example, as shown in FIG. Slide to the upper end side of the first elongated hole 14b, and tighten the nut 16b at the upper end position. In this state, the connecting bolt 16 is located at the upper end of the first elongated hole 14b and is supported by the lower end of the second elongated hole 15b.

  Then, the second metal fitting 15 is positioned and fixed with respect to the first metal fitting 14 fixed to the lower end portion 10b of the ceiling frame hanging member 10. Therefore, in the same state, the drill screws 12, 12 are screwed and fixed to the lower end portion 10b of the ceiling frame hanging member 10 through the drill screw insertion holes 15c, 15c on the left and right side walls of the first fitting portion 15a. . Thereby, the second metal fitting (main metal fitting) 15 for attaching the ceiling frame to the ceiling frame hanging member 10 is positioned at an appropriate height (the connecting bolt 16 is positioned at the upper end of the first elongated hole 14b, and (A state located at the lower end of the second long hole 15b).

  Therefore, after that, the field edge receiver 6 on the ceiling frame side is fitted to the second fitting portions 15d, 15d of the second metal fitting 15, and the drill screws 12, 12 are screwed through the drill screw insertion holes 15e, 15e. In this case, the field margin receiver 6 on the ceiling frame side is adjusted and attached to an appropriate height position, and the ceiling frame is attached to an appropriate height position.

(2) Height adjustment to the first long hole 14b intermediate position: see the state of FIG. 53 In the same manner as above, the first metal fitting 14 attached to the lower end 10b of the ceiling frame hanging material 10 A temporary fixing state in which the second metal fitting 15 is fitted via the connecting bolt 16 (the connecting bolt 16 is not yet completely tightened by the nut 16b, and the drill screws 12, 12 are not fixed to the ceiling frame suspending member 10). If the ceiling frame at that time is too high or too low in a state where the second metal fitting 15 is not screwed to the lower end portion 10b), the second metal fitting 15 is moved downward, as shown in FIG. Alternatively, the connecting bolt 16 is lifted upward to slide the connecting bolt 16 to an intermediate position in the vertical direction of the first elongated hole 14b, and the nut 16b is tightened at the intermediate position. In this state, the connection bolt 16 is in a state of being supported at a position vertically intermediate between the first elongated hole 14b and the second elongated hole 15b.

  Then, the second fitting 15 is positioned with respect to the first fitting 14 fixed to the lower end portion 10b of the ceiling frame hanging member 10 in a state in which the height is adjusted downward or upward, and And fixed. Therefore, in the same state, the drill screws 12, 12 are screwed and fixed to the lower end portion 10b of the ceiling frame hanging member 10 through the drill screw insertion holes 15c, 15c on the left and right side walls of the first fitting portion 15a. . Thereby, the second metal fitting (main metal fitting) 15 for attaching the ceiling frame to the ceiling frame hanging member 10 is positioned at an appropriate height (the connecting bolt 16 is connected to the first elongated hole 14b and the second elongated hole 15b, respectively). In the middle of the

Therefore, after that, the field edge receiver 6 on the ceiling frame side is fitted to the second fitting portions 15d, 15d of the second metal fitting 15, and the drill screws 12, 12 are screwed through the drill screw insertion holes 15e, 15e. When they are fitted, the field margin receiver 6 on the ceiling frame side is adjusted and mounted at an appropriate height position, and the ceiling frame is mounted at an appropriate height position.
(3) Adjustment of the first slot 14b to the lower limit position: the state of FIG. 54 The connection bolt 16 is attached to the first metal fitting 14 attached to the lower end 10b of the ceiling frame hanging member 10 in the same manner as described above. (The connecting bolt 16 is not yet completely tightened by the nut 16b, and the drill screws 12, 12 are not fixed to the lower end 10b of the ceiling frame hanging member 10). If the ceiling frame at that time is too high in the state where the ceiling frame is not screwed in, the second metal fitting 15 is lowered downward and the connection bolt 16 is moved to the first position as shown in FIG. 54, for example. Slide to the lower end side of the elongated hole 14b and tighten the nut 16b at the lower end position. In this state, the connecting bolt 16 is located on the upper end side of the second elongated hole 15b and is supported by the lower end of the first elongated hole 14b.

  Then, the second metal member 15 is finally positioned and fixed with respect to the first metal member 14 fixed to the lower end portion 10b of the ceiling frame hanging member 10. Therefore, in the same state, the drill screws 12, 12 are screwed and fixed to the wall of the lower end portion 10b of the ceiling frame hanging material 10 through the drill screw insertion holes 15c, 15c on the left and right side walls of the first fitting portion 15a. I do. Thereby, the second metal fitting (main metal fitting) 15 for attaching the ceiling frame to the ceiling frame hanging material 10 is positioned at an appropriate height (the connecting bolt 16 is located at the lower end of the first elongated hole 14b, and 2 (a state located at the upper end of the long hole 15b).

<About the suspension structure of the ceiling frame according to Embodiment 14 of the present invention: see FIGS. 55 to 59>
Next, FIGS. 55 to 59 show a hanging structure of a ceiling frame according to Embodiment 14 of the present invention.

  The structure of this embodiment is, for example, as shown in FIGS. 55 to 59, in which the length of the first metal fitting 14 in the structure of the thirteenth embodiment in the up-down direction is vertically increased by a predetermined dimension, and both ends thereof On the left and right sides, fitting claws (holding ribs) 14e, 14e, 14e, 14e of a predetermined length to be fitted to the ceiling frame hanging member 10 are provided.

  In the configuration of the thirteenth embodiment, when attaching the first metal fitting 14 as a base to the lower end 10 b of the ceiling frame hanging material 10, the lower end line of the first metal fitting 14 is connected to the lower end of the ceiling frame hanging material 10. The first metal fitting 14 is positioned with respect to the ceiling frame hanging material 10 by attaching the left and right side lines to the left and right side surface lines of the ceiling frame hanging material 10 so as to coincide with the lower end surface line of 10b. Then, the second metal fitting 15 is attached.

  In this manner, the entire first metal fitting 14 is mounted coaxially with the lower end 10b of the ceiling frame hanging member 10, and the first elongated hole 14 is also connected to the lower end 10b of the ceiling frame hanging member 10. And extend in the vertical direction coaxial with the axis.

  However, in the case of such an attachment method, the lower end face of the first metal fitting 14 and the lower end face of the lower end portion 10b of the ceiling frame hanging material 10 coincide with each other, and the right and left side faces of the first metal fitting 14 and the ceiling frame. The operator merely visually judges the line coincidence with the left and right side surfaces of the hanging member 10, it is difficult to accurately position the line, and the first bracket 14 is inclined with respect to the ceiling frame hanging member 10. It is unavoidable that the first elongate hole 14b is attached in an inclined state.

  When the first elongated hole 14b is attached to the ceiling frame hanging member 10 in such a manner as to be inclined, the second metal fitting 15 fitted to the ceiling frame hanging member 10 smoothly moves in the vertical direction. There is a problem that it is not possible to perform appropriate height adjustment without sliding.

  Also, the flat flange-shaped fixing portions 14c, 14c of the first metal fitting 14 are overlapped on the flat wall surface of the ceiling frame hanging material 10 with their lower end surfaces and side surfaces aligned, and are pressed accurately by hand. The operation of screwing into a proper position with the drill screws 12 is not easy, and a positional shift is likely to occur due to the rotational force or vibration at the time of screwing the drill screw.

  This embodiment is made to solve such a problem. For example, as shown in FIGS. 55 and 56, a first metal fitting 14 having the same configuration as the first metal fitting 14 of the above-described thirteenth embodiment is used. The length of the metal fitting 14 in the vertical direction is increased by a predetermined length, and fitting claws (holding ribs) 14e fitted on the left and right sides of the ceiling frame hanging material (square steel pipe) 10 on the upper and lower ends. , 14e, 14e, 14e.

  In this case, the fitting claws (holding ribs) 14e, 14e, 14e, 14e are formed by extending a part of the flange-shaped fixing portions 14c, 14c on both sides of the bolt mounting portion 14a to the left and right sides and bending them at right angles. However, if possible, it is bent slightly smaller than 90 degrees so as to exert a certain holding force (binding force), or a small projection that exerts a reliable engaging force on the front-side mating surface or the entire mating surface. It is preferable to provide a part.

  With such a configuration, when the first metal fitting 14 is attached to the ceiling frame hanging member 10, the fitting force of the fitting claws (holding ribs) 14e, 14e, 14e, 14e is used to make the ceiling. As long as the first metal fittings 14 are fitted to the frame hanging member 10, the fitting claws 14e, 14e, 14e, 14e are securely attached along the ceiling frame hanging member 10 by fitting the fitting claws 14e, 14e, 14e, 14e. In the attached state, it is possible to simply and reliably align the positions of the lower end surfaces by merely hitting a receiving surface member on the lower end surface side and lightly tapping the first metal fitting 14 from above.

  Then, in the temporarily fixed state by the fitting, the drill screws 12, 12 may be screwed together, so that the screwing work of the drill screws 12, 12 is easy, and the displacement at the time of screwing hardly occurs.

  Therefore, not only can the first metal fitting 14 serving as a basis for mounting the second metal fitting 15 to be adjustable in height be accurately positioned and held, but also the first metal fitting 14 as in the thirteenth embodiment described above. The fixing work efficiency at the time of mounting the first metal fitting 14 is far better than the case where the lower ends of the flange-shaped fixing portions 14c, 14c are overlapped and screwed together with the drill screws 12, 12 while holding them by hand. Become.

  56, the pair of fitting claws 14e, 14e, 14e, 14e on the upper and lower ends on the right and left sides when the second fitting 15 is fitted. Since the positioning of the fitting portion with respect to the first metal fitting 14 and the function of guiding the fitting are performed, the operation of fitting the second metal fitting 15 to the first metal fitting 14 becomes reliable and easy.

  As a result, in the above configuration, in addition to accurate and easy positioning and mounting of the first metal fitting 14, positioning and mounting of the second metal fitting 15 are accurate and easy. And the ceiling frame can be attached more accurately and securely.

  As for the adjustment of the height position, for example, as shown in FIG. 56, each of a pair of fitting claws (holding ribs) 14e, 14e, 14e, 14e on the upper and lower ends of the first metal fitting 14 is provided. The first and second fitting portions 15a, 15d of the second metal fitting 15 can be adjusted so that the heights (spans) b, b between the upper and lower sides can be adjusted in the same manner as in FIGS. 52 to 54 of the above-described embodiment. And the length of the first elongated hole 14b in the first metal fitting 14 in the vertical direction is made sufficiently long, for example, as shown in FIGS. Similarly to the above-described cases (1) to (3) of the thirteenth embodiment, the connection bolt 16 is moved to the upper limit position, the middle position, and the lower limit position of the first elongated hole and fixed to attach the ceiling frame. Can be fixed at a desired height position.

  In this case, the upper and lower widths c of the pair of right and left fitting claws (holding ribs) 14e, 14e, 14e, 14e on the upper and lower ends of the first metal fitting 14 take into consideration the maintenance of the fitting force and the strength at the time of fitting. To form appropriate dimensions. Even if the bending angle is slightly smaller than 90 degrees, a round surface having a predetermined curvature is formed at the corner of the rectangular steel pipe constituting the ceiling frame hanging member 10, so that the fitting operation is not performed. The work is very easy.

<About the ceiling frame hanging structure according to Embodiment 15 of the present invention: see FIGS. 60 and 61>
60 and 61 show a hanging structure of a ceiling frame according to Embodiment 15 of the present invention.

  The ceiling frame connection fittings (connection fitting units) 14 and 15 in the ceiling frame suspension structure according to the fourteenth embodiment can be securely and coaxially mounted on the ceiling frame suspension member 10 in parallel. The positioning is accurate, the stability after mounting is high, and no displacement occurs when the drill screw is screwed. If the length in the vertical direction is increased, a sufficient span length can be ensured.

  However, in the case of the same configuration, since the adjustment position of the ceiling frame hanging member 10 to the lower limit side is regulated by the right and left fitting claws 14e, 14e on the lower end side of the first metal fitting 14, the figure in the thirteenth embodiment is used. As can be understood by comparing FIG. 54 with FIG. 59 in the fourteenth embodiment, free position adjustment to the lower end side as in FIG. And the lower end of the ceiling frame hanging member 10 protrudes downward by a predetermined dimension.

  Therefore, in this embodiment, in order to solve such a problem, for example, as shown in FIG. 60, the fitting claws 14e, 14e on the lower end side of the first metal fitting 14 in the connecting metal fitting unit are eliminated. The upper end side left and right fitting claws 14e, 14e are fitted to the ceiling frame hanging member 10 only.

  With such a configuration, the above-described problem in which the adjustment position of the ceiling frame hanging member 10 to the lower limit side is restricted by the fitting claws 14e, 14e on the lower left side can be surely solved. As shown in FIG. 54, as in the case of FIG. 54 in the thirteenth embodiment, the position can be adjusted and set with a margin at a position lower than the lower end of the ceiling frame hanging member 10.

  In addition, in the case of this embodiment, the first metal fitting 14 is securely fixed to the ceiling frame hanging member 10 at least by the fitting claws 14e, 14e on the left and right sides on the upper end side. In the same manner as in the case where the fitting claws 14e, 14e, 14e, 14e are provided, stable positioning and mounting can be maintained, so that no displacement occurs when the drill screws 12, 12 are screwed.

  In this case, in order to increase the fitting force of the fitting claws 14e, 14e to the ceiling frame hanging material 10 and the positioning stability, the vertical width c of the fitting claws 14e, 14e may be increased as necessary. A configuration is employed.

<About the suspension structure of the ceiling frame according to Embodiment 16 of the present invention: see FIGS. 62 to 65>
62 to 65 show a hanging structure of a ceiling frame according to Embodiment 16 of the present invention.

In the case of the configuration of the first metal fitting 14 of the ceiling frame connecting metal fitting (connecting metal unit) in the hanging structure of the ceiling frame according to the fifteenth embodiment, there is no fitting claw 14e on the left and right sides on the lower end side. Like the first metal fitting 14 of the ceiling frame connecting metal fitting (connecting metal unit) in the ceiling frame hanging structure according to the fourteenth aspect, the adjustment position of the ceiling frame hanging material 10 to the lower limit side is the first metal fitting 14. 54, the position can be freely adjusted to the lower end side as shown in FIG. 54 in the thirteenth embodiment, and the ceiling frame suspending member can be adjusted. The lower end of 10 does not protrude downward.

However, it is undeniable that the positioning and temporary fixing functions on the lower end side are reduced by the amount of the engagement claws 14e, 14e on the left and right sides on the lower end side, and the positional deviation at the time of screwing the drill screw is likely to occur.

Therefore, in this embodiment, a fitting claw is also provided on the lower end side of the first metal fitting 14 in order to solve such a problem and facilitate alignment with the lower end surface of the ceiling hanging member 10. However, the present invention is characterized in that the claw portions are provided not on the left and right sides of the lower end of the first metal fitting 14 as in Embodiment 14, but on the left and right sides of the end face of the lower end.

That is, in this embodiment, the fitting claws to be fitted to the ceiling frame hanging member 10 provided on the metal fitting body of the first metal fitting 14 are provided on both upper end portions of the first metal fitting 14. First fitting claws 14e, 14e fitted on both left and right sides of the ceiling frame hanging material 10, and first metal fittings of the ceiling frame hanging material 10 on the left and right of the lower end face of the first metal fitting 14. It is composed of second fitting claws 14f, 14f that are brought into contact with the left and right ends of the lower end of the mounting surface.

In this case, the first fitting claws 14e and 14e and the second fitting claws 14f and 14f are formed by bending a part of the metal fitting body of the first metal fitting 14 toward the ceiling frame hanging member 10 by 90 degrees. Have been.

According to such a configuration, when the first metal fitting 14 is fixed to the lower end 10b of the ceiling frame hanging member 10, the second fitting claws 14f, 14f on the lower end face of the first metal fitting 14 are fixed to the ceiling frame. The lower fitting end surface of the first metal fitting mounting surface of the hanging member 10 is abutted and engaged to determine the mounting position in the vertical direction, and the first fitting claws on both sides of the upper end of the first metal fitting 14. By fitting 14e, 14e to both sides of the ceiling frame hanging member 10, the mounting position in the left-right direction can be determined, and the whole can be temporarily fixed. That is, according to the configuration, the upper, lower, left, and right mounting positions can be accurately positioned, temporarily fixed securely, and then fixed with a drill screw.

As a result, even if the operator does not support it by hand, the positioning state is reliably maintained, and even if the drill screw is screwed, it can be accurately fixed without any displacement.

Therefore, not only the workability when fixing the first metal fitting 14 to the ceiling frame hanging member 10 is improved, but also the ceiling fitting via the first metal fitting 14 of the second metal fitting 15 for fitting and fixing the ceiling metal frame. The adjustment of the mounting position with respect to the frame hanging member 10 is facilitated, and the mounting accuracy of the ceiling frame with respect to the ceiling frame hanging member 10 is also improved.
