Description

  The present invention relates to a unit structure and a renewal method in a steel structure unit building.

  In the unit building, unit structures that make up each room such as bathroom, kitchen, toilet, etc. are manufactured at the factory, and each unit structure is individually transported to the site by truck, and the unit structures are mutually connected at the construction site. The house is assembled and integrated.

  Conventionally, when a unit structure of a unit building is manufactured at a factory, first, the floor frame, the column, and the shed frame are individually manufactured as the minimum unit members, and (1) First, the column is vertically placed on the floor frame. Weld and join in a fixed state. (2) Next, a hut frame is placed on a vertical column and welded in a fixed state so as not to drop (examples of welding joint include Patent Documents 1 and 2).

  In the conventional unit structure manufactured in the steps (1) and (2), careful welding is required at a portion of the unit frame that is important in terms of strength. In addition, the welding and joining of the column frame and the cabin frame requires work with the same height as the column height.

  On the other hand, in the unit structure, when a welding defect is found, a replacement work performed by cutting the column frame is required. In this case, in the welding joint, the column frame is improved by removing the welding path that has melted into the floor frame and shed frame, but this reduces the thickness of the steel frame, which is very difficult work. I need.

  Also, if the unit building is damaged or becomes a second-hand product, it will be necessary to repair it, but in this case as well, if the unit structure is assembled by the welding joint method, old building members and damaged frame members will Then, the joining portion is melted, and as described above, the entire frame of the unit structure at that portion is replaced.

Furthermore, when it becomes necessary to replace the outer wall attached to the unit structure, it is necessary to remove the waterproofing material at the contact portion between the outer wall and the unit structure frame for welding joining before installing the new outer wall. . In this case, since all the continuous portions of the adhesive member are removed, the replacement of the outer wall material extends beyond the necessary portion, and the waterproof treatment material is similarly repaired.

  In the unit structure in a conventional unit building that assembles the floor frame and pillar and between the shed frame and the pillar frame by welding joint, the floor, pillar and shed frames cannot be separated unless the frames are destroyed. Because of the body, even when replacing old or damaged parts with new ones, the old frame cannot be replaced without destroying it, and it takes time to replace the old frame and recycle (renew) the old frame. The structure was uneconomical from the viewpoint of effective use of resources.

In the unit structure of the unit building, the present invention was created by paying attention to the fact that the non-welding method is superior in terms of work efficiency and safety. By making each frame unit in the hut and building each frame unit with a non-welding method, it is possible to easily replace without destroying only the frame members that need replacement such as defective column frames, It solves the conventional problems.

  In order to achieve the above object, the present invention is configured as follows.

  According to a first aspect of the present invention, in a unit structure of a unit building, a floor frame unit constructed by assembling and integrating shape steel, a column frame unit, and a shed frame unit serve as a minimum unit frame member of the unit structure, and the floor It is characterized in that a unit frame main body of a steel frame ramen structure without welding is constructed by bolting and integrating the frame units of the pillar and the hut.

  In the second invention, in the first invention, each frame unit of the floor, pillar, and shed constituting the unit frame body in the unit structure has various buildings such as an outer wall material, a ceiling material, a floor material, a doorway, and a window sash. A fitting groove capable of fitting a member is formed, and the various building members are attached to the fitting groove by a fitting method or a dropping method.

The third invention is the above-described bolt connection of various building members such as floor, pillar, and shed frame units and outer wall materials, ceiling materials, floor materials, doorways and window sashes in the unit structure of the first or second invention. And disassembling in units of floor, pillar, and shed frame units and each building member by disassembling the fitting joint and dropping fitting joint, and reassembling and re-enabling the unit. To do.

  According to the present invention, it is possible to individually control the quality after producing the floor frame, the pillar frame, and the shed frame constituting the structure of the unit building as components (minimum constituent unit elements). Further, the place where the unit structure is assembled is not particularly particular, and it is easy to ensure the quality of the entire structure by welding-free joining, but it is also efficient from the viewpoint of workability and safety. Furthermore, by constructing the unit structure of the unit building as a steel frame structure by an assembly method using a non-welding method, in addition to being excellent in terms of work efficiency and safety, aging such as defective columns Only damaged or damaged members can be replaced with new ones without destruction, and reuse (renewal) can be facilitated, and resources can be used effectively.

  When the unit building according to the present invention was constructed and the strength was confirmed by performing a pressure test and a lifting test on the unit structure, the tenth strength by the non-welding method could be confirmed.

  Furthermore, according to the present invention, a building such as a ceiling material, an outer wall material, a flooring material, and a roofing material is placed in the unit structure by a fitting method or a dropping method, finished into a unit building, the unit building is dismantled, and a new structure is created. It was confirmed that renewal can be done easily by replacing or replacing flooring materials, exterior wall materials, doorway and window sashes, ceiling materials, roofing materials, and pillars. In addition, it was confirmed that the layout of the building unit could be changed by changing the layout of the outer wall material, the entrance and exit, and the window sash.

  In order to contribute to the effective utilization of resources in recent years, the third invention is important, and in particular, steel frames, outer wall panels, ceiling panels, flooring materials, and roofing materials are necessary rather than being renewed as a whole. It is more effective to replace only a small member.

  In addition, in the third invention, each member is assembled by dropping and fitting, the unit building is loaded on the truck, transported and lifted repeatedly, and as a result of repeated pressurization tests, each frame subjected to pressurization is distorted. It was confirmed that there was no influence such as.

The combination of the inner and outer floor frames 14a and 14b may be a combination of a lightweight grooved steel with a lip and a shape steel as shown in the figure, or may be a combination of other shape steels having various cross-sectional shapes. The joists 22 are mounted on the upper part of the inner floor frame 14a and are fixed together by welding or the like.

  The shed frame 16 shown in FIG. 11 and FIG. 12 supports a main building material 21 arranged in parallel at a predetermined interval on a square frame of two sides of a rectangular frame. Is particularly referred to as Oiragi 20. The frame that is bolted together with the large beam 20 back to back is referred to as a large beam outer frame 26. Further, the frame spanning between both ends of the parallel girder 20 and the girder outer frame 26 is also made of inner and outer members, which are referred to as an inner shed frame 28a and an outer shed frame 28b. The structure of the cabin frame 16 is defined as described above, and will be described below.

  10 and 11, in the joint structure of the corner and column head of the shed frame 16 where the girder 20 and the girder outer frame 26 and the inner and outer shed frames 28a and 28b intersect at right angles, the girder 20 and the outer girder frame 26 are T The both side surfaces of the first plate 25 a of the character-shaped column head joining plate 25 are sandwiched and fixed by high tension bolts 27.

  As shown in FIGS. 7 and 8, the girder 20 and the girder outer frame 26 are each formed by placing a shape steel having a groove portion such as a light-weight grooved steel or a grooved steel back to back, and with a high tension bolt 27. The upper chord material 20a, the inner lower chord material 20b, the outer upper chord material 26a, and the outer lower chord material 26b are combined together. The outer girder outer frame 26 (that is, the outer upper chord member 26a and the outer lower chord member 26b) is provided in order to further increase the strength of the shed frame without increasing the beam height of the two beams 20 divided vertically.

  As shown in FIGS. 11 and 12, the inner and outer cabin frames 28 a and 28 b arranged on the other side at right angles to the girder 20 and the outer beam frame 26 are formed on the second plate 25 b of the T-shaped column head joint plate 25. Adhering to each other, both side surfaces are sandwiched and fixed with high tension bolts 27. The combination of the inner and outer floor frames 28a and 28b may be a combination of lightweight grooved steel with lips and a shape steel, or may be a combination of shapes of various other cross-sectional shapes.

  The main beam 20 has a purlin insertion gap 30 formed between the upper chord member 20a and the lower chord member 20b which are divided into two parts, and the purlin insertion gap 30 (shown in FIG. 7 and FIG. 8) is made of groove steel. An end of the main purlin 21 is inserted and supported. The fixing means between the end portion of the purlin 21 and the girder 20 is arbitrary, and may be either welded joint or bolt joint.

The beam back height (Dh) of the large beam 20 is the total height of the height (h ₄ ) of the upper chord material 20 a, the height (h ₅ ) of the purlin material insertion gap 30 and the height of the lower chord material 20 b (h ₆ ). Yes, the beam back height (Dh) is set to the same beam back height as that of a conventional large beam. Therefore, in the present invention, the purlin member 21 is supported within the height (Dh) range of the main beam 20 by being supported by the main member insertion gap 30, and is supported in series on the upper portion of the conventional main beam. In this case, the height dimension of the main building material 21 can be reduced, and the ceiling material can be arranged at a higher part accordingly.

  FIGS. 13A to 13C are explanatory views showing three embodiments of the floor frame unit 14. The figure (a) shows a joist made of any one of a grooved steel, a steel pipe and an H-shaped steel on a floor beam formed by joining an outer floor frame 14b made of a grooved steel to the outside of a floor frame unit 14 made of a grooved steel. The example which supported 22 is shown. FIG. 2B shows an example in which the joist 22 is supported on a floor beam formed by joining an inner floor frame 14a made of channel steel to the inside of a floor frame unit 14 made of channel steel. FIG. (C) shows an example in which the joists 22 are supported on a floor beam formed by joining an inner floor frame 14a made of a steel pipe to the inside of a floor frame unit made of a steel section steel.

  14A to 14F are explanatory views showing six embodiments of the girder 20 and the purlin member 21 in the shed frame unit 16. FIG. 4A shows an example in which a purlin member 21 made of any one of a grooved steel, a steel pipe, and an H-shaped steel is supported by a girder 20 composed of an upper chord member 20a and a lower chord member 20b made of a grooved steel. Show.

  FIG. 14B shows an example in which the purlin member 21 is supported by a girder 20 composed of an upper chord member 20a and a lower chord member 20b made of a steel pipe. FIG. 5C shows an example in which the main building material 21 is supported by a girder 20 composed of an upper chord member 20a and a lower chord member 20b made of steel section steel. FIG. 4D shows an example in which the purlin member 21 is supported by a girder 20 composed of an upper chord member 20a made of a steel pipe and a lower chord member 20b made of channel steel.

  FIG. 14 (e) shows an example in which the purlin 21 is supported by a large beam 20 made of a single beam made of any one of a grooved steel, a steel pipe, and an H-shaped steel. FIG. 5 (f) shows an example in which the main building material is supported by a large beam 20 made of a beam material made of H-shaped steel.

  In addition, as the unit structure 11, a member having a larger beam strength and rigidity is used as the span becomes larger. In the present invention, the purlin member 21 is in the middle of the upper chord member 20a and the lower chord member 20b of the main beam 20, so that the main member 21 functions as a chord member of the lattice beam and has a beam height (Dh) of the conventional large beam. Even if the large beam 20 is divided into two within the range, the strength of the large beam 20 does not decrease. Furthermore, the strength and rigidity of the girder 20 can be adjusted by adjusting the blister material 21.

  The main building material 21 is accommodated within the range of the beam back height (Dh) of the girder 20, and the ceiling material 31 and the roof material 32 are also accommodated within the range of the height (Dh) of the girder 20 for support. For example, the structure shown in FIG. 15 is preferable. That is, in the girder 20, the end portion of the ceiling material 31 is inserted into and supported by the groove opening portion 33 by using the groove opening portion 33 of the inner lower chord member 20 b made of channel steel located below the purlin member 21. Thereby, the ceiling material 31 can be stored and supported within the range of the height (Dh) of the large beam 20.

  As shown in FIG. 15, the roofing material 32 can also be accommodated within the range of the beam back height (Dh) of the large beam 20. That is, in the present invention, by supporting the purlin member 21 between the inner upper chord member 20 a and the inner lower chord member 20 b divided above and below the large beam 20, the upper end portion of the large beam 20 is positioned higher than the upper surface of the purlin member 21. Therefore, when the valley portion 32a of the roof material 32 having the folded structure as shown in the figure is arranged on the upper surface of the main building material 21, the mountain portion 32b is substantially the same height as the upper end portion of the girder 20. The mountain portion is not arranged at a high position from the upper part of the main building material like the conventional roofing material.

  At the end of the roofing material 32, the mountain part 32 b is arranged so as to cover the upper part of the large beam 20, but the valley part 32 a of the roofing material 32 is dropped to the vicinity of the upper surface level of the main building material 21, so this At the end, only the thickness of the steel plate of the roofing material 32 may be considered, and the roofing material 32 is substantially disposed within the range of the beam back height (Dh) of the large beam 20. When the roofing material 32 is made of a flat steel plate, it functions in the same manner as described above, and the flat roofing material is arranged at the upper surface level of the purlin 21 and the raised portion formed at the edge thereof covers the upper part of the girder 20. As a result, the same function as described above is achieved.

  As described above, by placing the roofing material 32 within the range of the beam back height (Dh) of the large beam 20, it is possible to minimize the building height while ensuring the maximum effective indoor height. effective.

  FIG. 16 is a schematic diagram showing the storage of the column frame unit 15 and the outer wall panel 1 and the like. The outer wall panel 1 and the like are placed in the groove opening 9 of the column frame unit 15 made of channel steel that is erected oppositely. Plugged in and supported. As shown in FIG. 4, when the intermediate column frame unit 15c is disposed between the columnar frame units 15 at the corners, the outer wall panel 1 or the like has a groove opening between the columnar frame unit 15 at the corners and the intermediate column frame unit 15c. It is supported between the portion 9 or the groove opening 9 between the intermediate column frame units 15c. In addition, even if it replaces and arrange | positions the window sash 2 and the entrance / exit sash 3 in the part of the outer wall panel 1, it is the same.

  FIGS. 17A to 17D are cross-sectional plan views showing four embodiments of the joint structure between the column frame unit 15 and the outer wall panel 1. FIG. 4A shows a column frame unit 15 made of a square steel pipe and is bent at a right angle along two sides intersecting at the outer corner portion thereof.

Show.

  FIG. 17B shows an outer wall panel that intersects from two right angles at a groove opening 9 of a column frame unit 15 formed by joining a plurality of lightweight grooved steels to a two-side plate of a column base joining plate 24 that intersects at right angles. The example which supported 1 is shown. FIG. 17 (c) shows an outer wall panel 1 that intersects from two right angles at a groove opening 9 of a column frame unit 15 formed by joining a plurality of channel steels to a two-face plate of a column base joining plate 24 that intersects at right angles. An example in which is supported.

  FIG. 17 (d) shows a column leg unit joining plate 24 positioned in a right angle method on one side of a web of a column frame unit 15 made of H-shaped steel and one flange, and one positioned in a right angle method. The outer wall panel 1 is joined to the inner side where one flange of the H-shaped steel and the web intersect, and the other outer wall panel 1 is supported by the groove of the receiving material 8 made of grooved steel fixed to the other flange of the H-shaped steel. An example is shown.

  Next, the function and effect of the embodiment will be described.

  In the present invention, the structural building frame of the unit building is constructed by assembling the frame unit 14, the column frame unit 15, and the cabin frame unit 16 using the high-tensile bolts 27, so the constructed unit building is damaged. It can be dismantled, recovered, replaced with new members, renewed and recycled.

  The structural frame of this unit building is divided into a floor frame unit 14, a column frame unit 15, and a shed frame unit 16, which can be produced individually, and the production of this member is a low-place work, ensuring safety and quality assurance. Easy to do.

  As described above, the column frame unit 15, the floor frame unit 14, and the cabin frame unit 16 are joined to each other by a welding method. And the operation | work which joins the pillar frame unit 15 is easy to join even if it does not fix completely, and can work | operate safely and quickly. Moreover, the column base part joining plate 24 and the column head part joining plate 25 are sandwiched between the outer floor frame 14a of the floor frame unit 14, the large beam 20, the large beam outer frame 20a, and the small indoor / outdoor frames 28a and 28b. Therefore, the column base joining plate 24 and the column head joining plate 25 are prevented from buckling, and the tightened high tension bolts 27 are sheared in two planes to double the strength.

  The column base part joining plate 24 and the pillar head joining plate 25 at the corners are attached in two orthogonal directions, and are joined by high tension bolts 27 in the respective directions. The joining plate in the two orthogonal directions can be fixed more stably because the high tension bolt 27 works effectively.

  The outer wall is in panel form. The outer wall panel 1 is dropped into a groove using the groove opening of the column frame unit 15 and serves as an outer wall and an inner wall. On the other hand, the ceiling panel 4 is fitted into a groove using the groove opening of the cabin frame unit 16 to constitute a ceiling.

  Since the outer wall panel 1 and the ceiling panel 2 have a drop-in construction method and a fitting-in construction method, there is no risk of damage to the panel or inconvenience due to frame distortion that occurs when the unit building is lifted, transported, or installed. It is easy to secure the performance. Assembling structure by inserting ceiling panel 2 and dropping roofing material 32, the unit building is loaded on the truck, transported and lifted repeatedly, and the effect of the distortion of the frame under pressure as a result of repeated pressurization tests Confirmed that there is no.

  Unit buildings collected after construction are dismantled for each structure frame (skeleton), flooring, outer wall, ceiling, and roofing. A steel frame as a structure can extend the life expectancy of the structure by replacing damaged or deteriorated members. On the other hand, floor materials, outer wall materials, ceiling materials, and roof materials are also damaged in the same way as steel frames, and only deteriorated members are replaced to ensure the performance of building materials. The restored unit building is renewed to extend the life expectancy as a building again.
