Description

  The present invention relates to a portal frame having a take-out beam.

  For example, in a steel frame construction house, a pillar made of rectangular steel pipe and a beam made of steel and the like are rigidly connected to each other as a primary member to form a rigid frame, and the frame is formed with this rigid frame. A structure has been proposed (see, for example, Patent Document 1).

  By the way, in a snowy area or an urban area, for example, a take-out beam is taken out from one construction surface (vertical construction surface) of the house, and a cantilever such as a balcony and a garage are formed above and below the take-out beam. In some cases, such a garage is called a build-in garage. In snowy areas, protect the vehicle from snow, etc. and allow access from the room to the vehicle without being exposed to wind and rain, and in urban areas, both garages and balconies are limited within the limited construction site area. Ensuring, etc. is one of the reasons for requesting the construction of the above-mentioned housing.

  In the construction of a general steel-framed house such as a one-story house to a three-story house, a frame structure is formed by connecting pillars and beams with medium bolts. When constructing a garage with a balcony or the like on the floor as described above for such a general house, the carry-out beam that supports the garage's floor (the floor such as the balcony) forms a vertical surface. It is constructed so that it is taken out from the beam or pillar. When such a takeout beam is taken out from the vertical construction surface, it is necessary to rigidly connect the takeout beam to the beam or column forming the vertical construction surface. A method of rigidly connecting the take-out beam by high-strength bolts or welding can be applied.

  However, in the construction of a general house, as described above, the connection between members is performed with medium bolts, so when performing construction using high-strength bolts only at some connection locations, connection with medium bolts In this case, the frictional surface treatment, torque management, and the like, which are unnecessary, are added, so that the workability is remarkably deteriorated. In addition, since the connection between members by welding is not generally performed in the field construction of ordinary houses, performing welding only on a part of the connection points increases the workability as in the case of using high-strength bolts. It can be a factor to decrease.

  In addition, medium bolts used in construction of ordinary houses are guaranteed corrosion resistance by plating treatment, etc., but high strength bolts are friction connection joints, so it is difficult to perform plating treatment like intermediate bolts There is also.

Japanese Patent Laid-Open No. 11-131663

  The present invention has been made in view of the above-described problems, and in the case where an overhang structure such as a build-in garage is constructed for a steel-framed house, a high strength is provided in a connection portion between main members at a construction site. It is an object of the present invention to provide a gate-type frame having a take-out beam that does not have a rigid connection portion that requires connection by bolts or welding, and that can therefore achieve good workability.

In order to achieve the above object, one aspect of the gate-type frame having a carry-out beam according to the present invention is
A gate-type frame having two ladder-type load-bearing walls and two gate-type beam beams connected to the two ladder-type load-bearing walls;
A carry-out beam carried out from the ladder-type load-bearing wall frame,
The ladder-type load-bearing wall frame is
Two metal vertical members parallel to each other, including a first vertical member inside the portal frame and a second vertical member outside the portal frame; and ,
A plurality of cross members disposed between the two vertical members at intervals in the longitudinal direction of the vertical members and connected to the vertical members,
The portal frame beam is pin-connected to the first vertical member,
The take-out beam is pin-connected to the second longitudinal member, and an end portion of the portal frame beam is pin-connected to a side surface of the take-out beam.

  According to this aspect, in the construction of a gate-type frame having a carry-out beam, the connection positions of the main members at the construction site are all pin-connected, so that connection of members by high-strength bolts or welding can be made unnecessary. Easy workability is obtained. Here, as an application of the gate-type frame having a take-out beam, this gate-type frame is a frame that forms an entrance opening of a garage (build-in garage), for example. The form in which the beam is extended is mentioned. That is, the takeout beam is pin-connected to the portal frame in a so-called takeout beam winning manner, and serves as a support beam for supporting a balcony or a room formed on a floor such as a garage. The take-out beam is pin-connected to the gate-type frame, and its end is pin-connected to, for example, a stay beam that forms the vertical structure of the house. Further, in a store / house building, the gate-type frame may form an entrance / exit opening of the store, and the carry-out beam may be used for a residence room, a balcony, or the like formed on the store. Here, the “pin connection” means a connection in which rotation of members at the connection portion is allowed and a bending moment is not generated (can be designed as) in the connection portion. In contrast, a “rigid connection” is a connection in which the angle formed between the members at the connection part does not substantially change even when an external force is applied, and a bending moment is generated (designed) at the connection part. Means. Examples of the connection form in which the angle formed between the members in the connection portion does not change even when an external force is applied include connection by a plurality of high-strength bolts and connection by welding such as groove welding.

  In order to connect the pillars and beams that form the portal frame (beams for the portal frame) to pins instead of rigid connections like ordinary frame frames, in this mode, a column consisting of ladder-type bearing walls is applied. . The ladder-type load-bearing wall frame has two vertical members and a plurality of horizontal members arranged at intervals in the vertical direction between the vertical members. In the ladder-type load-bearing wall frame, each structural member is set so that when a horizontal force during a large earthquake is applied instead of a normal earthquake, the cross member yields in advance. By pre-yielding the cross member in this way, the two vertical members can maintain the initial rigidity in the event of a large earthquake, and it is possible to eliminate the collapse of the house. In addition, the cross member arrange | positioned at intervals in the up-down direction between vertical members can also be called a binding material. For example, a vertical member may be formed from a square steel pipe or the like, and a cross member may be formed from a shape steel material such as a shape steel having rigidity lower than that of the square steel pipe or the like. Further, in this cross member, a prior yielding of the cross member may be promoted by opening a hole for inducing shear yield. Various dampers may be applied to the cross member.

  The portal frame constructed by pin-connecting two ladder-type load-bearing wall frames and the beam for the portal frame is a frame in which members are pin-connected, but when subjected to repeated loads during a large earthquake The displacement-load hysteresis loop is drawn as a spindle-type hysteresis loop like a rigid frame formed by rigidly joining a beam and a column, in other words, it has the same energy absorption performance as a rigid frame. Specified by the inventors.

  Pin connection between the first vertical member that forms the ladder-type load-bearing wall and the beam for the gate-type frame, pin connection between the second vertical member that forms the ladder-type load-bearing wall and the carry-out beam, and the gate-type frame Any pin connection between the end of the beam and the take-out beam can be realized by, for example, a plate-to-plate connection method using a medium bolt, which is generally applied in the field construction of a general house. In addition, a connection jig that sandwiches and fixes two plates like a vise may be applied. Even in the case of a gate-type frame having a take-out beam, the main members are all connected to each other at the construction site by pin connection, so that the work of rigidly connecting the take-out beam by high-strength bolts or welding becomes unnecessary. Note that when both the take-out beam and the gate-type frame beam are formed of a shape steel material such as H-shaped steel, both beams are pin-connected to each other so that the strong axes are orthogonal to each other. End plates can be fixed to both the end of the beam for the building frame and the side surface of the take-out beam, and both end plates can be pin-connected with an intermediate bolt or the like.

Further, in another aspect of the gate-type frame having a take-out beam according to the present invention, the end portion of the gate-type frame beam has a height lower than that of the general portion of the gate-type frame beam. And a stepped portion made of metal having an upper end level at the same level as the general portion is provided,
The step portion is placed on the first vertical member and pin-connected to the first vertical member, and an end portion of the step portion is pin-connected to the take-out beam,
The upper end level of each of the take-out beam and the portal frame beam is the same level.

  According to this aspect, in the case where the span of the gate-type frame beam is increased to accommodate a wide garage opening or the like and the beam formation of the gate-type frame beam is increased to have a corresponding bending strength, The beam can be installed on the left and right ladder type load-bearing wall frames with the upper end level aligned over the entire length of the beam. In this erected state, the upper end levels of both the portal frame beam and the take-out beam can be set to the same level. Therefore, the top level of the gate-type frame beam can be aligned to the same level as, for example, the stay beam in the vertical structure of the house to which the takeout beam is pinned, and the vertical structure of the house from which the takeout beam is taken out. It is possible to make the beam, the takeout beam pin-connected to the beam, and the gate-type frame beam pinned to the takeout beam all at the same level.

  Here, the metal step portion can be formed from, for example, a square steel pipe. In factories, etc., a square steel pipe that forms a step is fixed to an end plate that is fixed to the end of a portal frame beam. It is possible to connect to the first longitudinal member of the ladder type load bearing wall frame via a medium bolt or the like.

Further, according to another aspect of the portal frame having a take-out beam according to the present invention, the height of the first vertical member is lower than that of the second vertical member, and the portal frame is above the first vertical member. And the end of the gate-type frame beam is pin-connected to the take-out beam,
The upper end level of each of the take-out beam and the portal frame beam is the same level.

  Even in this mode, when the span of the gate-type frame beam is increased and the beam formation of the gate-type frame beam is accordingly increased, the upper end level of the gate-type frame beam is set to the same level over the entire length of the beam. It can be installed on the ladder-type load-bearing wall frame in the aligned state, and can be aligned at the same level as the upper end level of the take-out beam. In this aspect, by adjusting the height of the first vertical member and the second vertical member that form the ladder-type load-bearing wall frame, it is possible to extend the entire length without providing a step portion at the end of the beam for the gate-type frame. A gate-type frame can be formed using the same beam-type beam for a gate-type frame.

  As can be understood from the above description, according to the gate-type frame structure having the carry-out beam of the present invention, when an overhang structure such as a build-in garage is constructed for a steel-framed house, the main members at the construction site There is no rigid connection point that requires connection by high-strength bolts or welding among the connection points, and therefore, it is possible to provide a portal frame having a take-out beam that can provide good workability.

[Embodiment]
<Example of housing>
First, with reference to FIG. 1, an example of a house including a gate-type frame having a takeout beam according to the embodiment will be described. FIG. 1 is a perspective view illustrating an example of a house including a gate-type frame having a take-out beam according to the embodiment. A house 100 shown in FIG. 1 is a two-story house using a lightweight steel frame or the like, and a built-in garage 10 is connected to a general part 30 of a house having a plurality of living rooms on the front side surface. It is a house. In addition, although the house 100 in the illustrated example is a two-story house having a flat roof, various forms can be applied to the roof type and the exterior shape of the house, and the structure is mainly a one-story to three-story steel structure. For housing.

  The garage 10 has an entrance / exit 11 at the front, and the vehicle is moved in and out by moving the electric shutter up and down as shown in the illustrated example. In addition, a balcony 20 is located on the floor of the garage 10, and the balcony can be accessed from the sweep window on the second floor. Thus, in the illustrated house 100, the garage 10 having the balcony 20 on the floor is connected to the front surface of the general part 30 of the house. A room may extend from the general part 30 of the house on the floor of the garage 10 instead of the balcony 20, or a store may be provided instead of the garage 10.

  A gate-type frame having a take-out beam, which is composed of a gate-type frame forming the entrance / exit opening 11 of the garage 10 and a carry-out beam connected to the gate-type frame and supporting the floor surface of the balcony 20, is shown in FIG. It becomes the frame of "Area". Hereinafter, a portal frame having a carry-out beam according to a plurality of embodiments will be described.

[Gate-type frame having a carry-out beam according to the first embodiment]
Next, with reference to FIG. 2 thru | or FIG. 4, the portal frame which has the taking-out beam which concerns on 1st Embodiment is demonstrated. Here, FIG. 2 is a diagram showing a model of a gate-type frame having a take-out beam according to the embodiment together with a model of a vertical structure of a house, and FIG. 3 has a take-out beam according to the first embodiment. It is a front view which shows a part of gate type frame. 3 shows only the left side of the gate-type frame beam, the right side configuration is the same as the left side configuration shown in the figure, and this also applies to FIGS. 5 and 6 showing other embodiments. apply.

  Among the model diagrams shown in FIG. 2, the model diagram of the general part of the house mainly shows the vertical composition of the front surface to which the carry-out beam 80 is pin-connected. In the model diagram shown in FIG. 2, when a member such as a beam or a column is pin-connected to another member, a circular model indicating the pin connection is connected to the tip of the beam model of the member to be pin-connected. ing.

  The gate-type frame 70 that forms the entrance and exit of the garage includes left and right ladder-type load-bearing wall frames 50 and gate-type frame beams 60 that are installed on the upper ends of these ladder-type load-bearing wall frames 50. The ladder-type load-bearing wall frame 50 includes two vertical members 51 and 52 and a plurality of horizontal members 53 disposed between the two vertical members 51 and 52 at intervals in the vertical direction.

  The first vertical member 51 is positioned inside the portal frame 70, and the second vertical member 52 is positioned outside the portal frame 70. The vertical members 51 and 52 are both formed from square steel pipes. On the other hand, the cross members 53 arranged and connected to the vertical members 51 and 52 at an interval in the vertical direction are made of groove steel having a rigidity lower than that of the square steel pipe. In addition, the combination of these square steel pipes and channel steels is an example, and as long as the rigidity of the cross member 53 is lower than that of the vertical members 51 and 52, various combinations such as a combination of a circular steel pipe and an H-shaped steel are possible. There can be a combination form. As shown in FIG. 3, a metal backing plate 54 is connected to the vertical members 51, 52 by welding or the like, and the end surface of the cross member 53 is connected to the backing plate 54 by welding or the like.

  As described above, when a plurality of cross members 53 having rigidity lower than that of the vertical members 51 and 52 are arranged between the vertical members 51 and 52, an excessive horizontal force is applied to the gate frame 70 in the event of a large earthquake. In addition, instead of the vertical members 51 and 52 of the ladder-type load-bearing wall frame 50 and the gate-type frame beam 60, each cross member 53 can be yielded in advance. Therefore, the longitudinal members 51 and 52 can maintain the initial rigidity even in the event of a large earthquake, and the collapse of the portal frame 70 can be eliminated while maintaining the upper load supporting ability of the longitudinal members 51 and 52. It is possible to repair the house 100 safely even after a large earthquake. The plastic deformation of the cross member 53, which is a spelling material, can basically be in-plane deformation. Therefore, the plastic deformation of the cross member 53 causes an exterior material made of an interior material such as a garage or a ceramic panel. There is little influence on That is, after a large earthquake, it is possible to restore the portal frame 70 by repairing only by replacing the plastically deformed cross member 53. The ladder-type load-bearing wall frame 50 is a member that is manufactured at a factory, transported to the site, and built, and is pin-connected to the portal frame beam 60 at the site after the building.

  The width B of the ladder-type load-bearing wall frame 50 is 1P (1P indicates a module width, for example, 910 mm), in addition to a width of 0.5P or 0.25P in order to increase the degree of freedom of opening of the portal frame 70. Various forms of width can be applied.

  An end plate 55 is connected to the upper end of each of the first longitudinal member 51 and the second longitudinal member 52 by welding or the like, and this welding process is performed at a factory. The portal frame beam 60 is formed of a shape steel material such as an H-section steel. A portal frame beam 60 is placed on the upper end of the first vertical member 51, and a flange below the portal frame beam 60 and the end plate 55 of the first vertical member 51 are pin-connected by a plurality of medium bolts 90. Is done.

  On the other hand, the take-out beam 80 connected to the portal frame 70 is also formed of a shape steel material such as H-section steel, and the portal frame 70 is connected to the continuous carry-out beam 80 as shown in the model diagram of FIG. In other words, the take-out beam 80 and the gate-type frame 70 are connected in a so-called form of a take-out beam. As shown in FIG. 3, an end plate 81 is connected by welding or the like to a side portion of the carry-out beam 80 where the portal frame beam 60 is connected. The carry-out beam 80 is placed on the end plate 55 at the upper end of the second vertical member 52 of the ladder-type load-bearing wall frame 50, and the flange below the carry-out beam 80 and the end plate 55 of the second vertical member 52 are a plurality of medium bolts. Pin connection is made at 90.

  Further, the end plate 81 of the take-out beam 80 and the end plate 61 at the end of the portal frame beam 60 are also pin-connected by a plurality of medium bolts 92.

  As described above, the main components constituting the portal frame 200 having the take-out beam are all connected at the site by standard bolt connection in construction of a general house using medium bolts. The members are not connected by high-strength bolts or welding, but the members are connected by, for example, about 4 to 6 medium bolts at each connection location. Is reasonable. Thus, favorable workability is obtained because all the connections in the field between the main constituent members are connections using medium bolts.

  In the portal frame 200 having the take-out beam shown in FIG. 3, the two vertical members 51 and 52 forming the ladder-type load-bearing wall frame 50 have the same length, and the take-out beam 80 and the gate-type frame beam 60 have the same length. The same is true for beam formation (beam formation h1). And as shown in FIG. 2, the edge part by the side of the house of the taking-out beam 80 is pin-connected to the pillar and beam which form the vertical construction surface of the general part of a house.

  In addition, by forming the gate-type frame 70 using the ladder-type load-bearing wall frame 50, the column and the beam are rigidly connected while the connection between the ladder-type load-bearing wall frame 50 and the gate-type frame beam 60 is connected to the pin. A portal frame having energy absorption performance similar to that of the formed ramen frame can be obtained.

  In FIG. 3, the connection configuration between the vertical members 51 and 52 and the foundation is omitted. A plurality of anchor bolts project upward from the top end of the foundation made of concrete, the anchor bolts are inserted into base plates (not shown) that form the column bases of the vertical members 51, 52, and tightened with nuts. The vertical members 51 and 52 are fixed to the foundation at the site.

  As shown in FIG. 2, in the illustrated example, a plurality of ladder-type load-bearing wall frames 50 and a gate-type frame beam 60 installed between the ladder-type load-bearing wall frames 50 also in the vertical structure of the general part of the house. The basic structure is a portal frame with As described above, since the load-bearing walls having various widths such as 1P width to 0.25P width can be applied to the ladder-type load-bearing wall frame 50, it is possible to increase the degree of freedom in opening the general part of the house. In addition, the construction surface of the general housing part may include a bearing wall other than the ladder-type bearing wall structure 50, for example, a bearing wall having a brace.

  Next, another embodiment of a cross member will be described with reference to FIGS. 4 (a) and 4 (b) are both perspective views showing an embodiment of a cross member. Only FIG. 4 (a) shows a vertical member 52 on one side of the cross member. The cross member 53 shown in FIG. 3 is applied with a groove steel having a rigidity lower than that of the square steel pipes forming the vertical members 51 and 52. However, the cross member 53A shown in FIG. It is common in the point formed. The cross member 53A shown in FIG. 4 (a) has a plurality of holes 53a on the left and right end sides connected to the vertical member of the channel steel. This hole is a hole for inducing that the cross member 53A precedes and yields a shear during a large earthquake, and can promote the pre-yield of the cross member 53A. The number and arrangement of the holes 53a with respect to the channel steel, the shape of the holes (circular in the illustrated example), and the like can be set as appropriate.

  On the other hand, the cross member 53B shown in FIG. 4B is made of a steel material having a cross-sectional shape orthogonal to the longitudinal direction of the cross member 53B. Since this Σ-type steel material has a diagonal material (an intermediate material between a vertical material and a horizontal material) in the center, this diagonal material has a vertical support performance that the vertical material has and a horizontal direction that the horizontal material has. Both of the deformation performances are to be obtained. Therefore, it is possible to effectively absorb the seismic energy with strength and suppleness against excessive horizontal force during a large earthquake. Although not shown, various dampers such as a viscoelastic damper, a viscous damper, and an elastoplastic damper may be applied to the cross member.

[Gate-type frame having a carry-out beam according to the second embodiment]
Next, with reference to FIG. 5, a portal frame having a carry-out beam according to the second embodiment will be described. Here, FIG. 5 is a front view showing a part of a gate-type frame having a carry-out beam according to the second embodiment. A portal frame 200A having a take-out beam shown in FIG. 5 is a portal frame having a portal frame beam 60 ′ having a long span so as to correspond to a wide garage opening or the like. Since the span of the gate-type frame beam 60 'is long, it is necessary to have an appropriate bending strength, and the beam formation of the gate-type frame beam 60' is increased (the beam of the gate-type frame beam 60 shown in FIG. 3). Beam formation h2) higher than the formation h1).

  The portal frame beam 60A in the illustrated example has a height lower than that of the general portion 60 ′ and the upper end level is the same as that of the general portion 60 ′ at both ends of the general portion 60 ′ of the gate-type frame beam having a high beam. A step portion 65 is provided. The step portion 65 is formed of a rectangular steel pipe having a height equal to that of the take-out beam 80 (height h1), and the inside of the steel pipe may be reinforced with a metal plate as in the case of an inner diaphragm as necessary.

  A general portion 60 ′ of the gate-type frame beam is formed of a shape steel material such as H-shaped steel, and an end plate 61 is connected to the end thereof by welding or the like, and a square steel pipe that forms a stepped portion 65 with the end plate 61. Are connected by welding or the like. The portal frame beam 60A is also manufactured at the factory, transported to the site, and pin-connected to the built-in ladder-type load-bearing wall frame 50 using medium bolts.

  As shown in FIG. 5, by applying a portal frame beam 60A having a step 65 having a relatively lower height than the general portion 60 ′ at both ends, a span is formed to accommodate a wide garage opening or the like. Therefore, even when the beam formation of the general portion 60 'is increased, the left and right ladder-type load-bearing wall frames 50 are arranged in a state where the upper end level is aligned over the entire length of the portal frame beam 60A. Can be erected. In this erected state, the upper end levels of both the portal frame beam 60A and the takeout beam 80 can be set to the same level. Accordingly, the upper end level of the gate-type frame beam 60A can be made to be the same level as that of the retaining beam in the vertical structure of the house to which the take-out beam 80 is pinned, and the vertical position of the house from which the take-out beam 80 is taken out. The beam of the construction surface, the take-out beam 80 pin-connected to the beam, and the portal frame beam 60A pin-connected to the take-out beam 80 can all be arranged at the same level.

[Gate-type frame having a carry-out beam according to the third embodiment]
Next, with reference to FIG. 6, a portal frame having a takeout beam according to the third embodiment will be described. Here, FIG. 6 is a front view showing a part of a gate-type frame having a carry-out beam according to the third embodiment. A portal frame 200B having a take-out beam shown in FIG. 6 is similar to the portal frame 200A having a take-out beam. It is.

  In the illustrated example, a ladder-type load-bearing wall frame 50A having a first vertical member 51A having a height lower than that of the second vertical member 52 is applied. The beam 60B for the gate-type frame having a high beam (the beam h2) is placed on the first vertical member 51A and pin-connected to the first vertical member 51A, and the end thereof is the gate-type beam 60B. By being pin-connected to the end plate 81 on the side of the take-out beam 80 having a lower height (height h1), the portal frame 200B having the take-out beam is formed.

  As described above, in the gate-type frame 200B having a take-out beam, the height of the second vertical member 52 and the first vertical member 51A is adjusted so that the stepped portion 65 is formed in the gate like the gate-type frame 200A having a take-out beam. In the state where the portal beam 60B is installed on the left and right ladder-type load-bearing wall frames 50 without being provided at the ends of the beam, the upper end levels of both the portal beam 60B and the take-out beam 80 are set. Can be aligned to the same level. Therefore, the upper end level of the gate-type frame beam 60B can be made to be the same level as the stay beam in the vertical structure of the house to which the carry-out beam 80 is pinned, and the vertical of the house from which the carry-out beam 80 is taken out. The beam of the construction surface, the takeout beam 80 pin-connected to the beam, and the gate-type frame beam 60B pinned to the takeout beam 80 can all be arranged at the same level.

  In addition, other embodiments in which other components are combined with the configurations described in the above embodiments may be used, and the present invention is not limited to the configurations shown here. . This point can be changed without departing from the spirit of the present invention, and can be appropriately determined according to the application form.
