Description

  The present invention relates to a unit building capable of forming a large space without a column by removing a temporary column and reinforcing this portion.

  In general, a unit house is constructed by transporting a required number of building units, which are produced by assembling pillars and beams in a box shape at a factory, to a building site and installing them sequentially using a crane. In this case, a part where the pillars of adjacent building units are gathered in one place is generated, which has been an obstacle to creating a wide space.

  Therefore, in recent years, a column-less type unit house called a wide span construction method has been proposed. In the case of this type of wide span method, transportability is ensured by attaching temporary columns to the building units in advance at the time of factory shipment, and the temporary columns are removed after the building units are sequentially installed in the building area. When the temporary column is removed, the strength of the part decreases, so a reinforcement beam is inserted between adjacent ceiling beams to make up for it, and the load that the temporary column should receive is borne (example) (See Patent Document 1 below).

The technology described in Patent Document 1 will be briefly described. In this prior art, portions where temporary columns in adjacent building units are removed are connected by a connecting member. Because this connecting member is in a positional relationship where it intersects with the reinforcing beam, if the connecting member is fixed to both sides of the reinforcing beam by welding in advance, if manufacturing errors or assembly errors accumulate, the reinforcing beam or connecting beam There is a possibility that the assembly of the members cannot be performed. Therefore, in order to avoid this problem, a slit having the same width as the thickness of the connecting member is formed in the reinforcing beam, and the connecting member is inserted into the slit so that the horizontal movement is possible. It absorbs assembly errors and enables assembly of reinforcing beams and connecting members.

  However, in the case of the above prior art, problems described below occur.

  That is, in this prior art, although the connecting member is movable relative to the reinforcing beam in the horizontal direction in order to enable assembly, the reinforcing beam and the connecting member are essentially integrated. Reinforce the part where the temporary pillars were removed and connect the removed parts of the temporary pillars of adjacent building units to each other, so that the vertical load from the upper floor side can be connected to the lower floor side via the reinforcing beams and connecting members. As a result, the load burden on the building unit side does not change. Therefore, the required strength and rigidity of the building unit alone cannot be reduced, and there are problems such as an increase in the weight of the building unit.

  Further, according to this prior art, since the vertical load from the upper floor side is transmitted from the reinforcing beam to the connecting member, the connecting member is likely to be deformed. For this reason, the structure of setting a stiffener vertically on the lower surface side of a connection member, and supporting a connection member with a stiffener is required. Here, stiffeners are fixed to both sides of the reinforcing beam in advance by welding or other means in order to reduce field work in the building site. In that case, the load of the reinforcing beam during transportation is large. Therefore, the problem that transportation efficiency falls arises. On the other hand, if stiffeners are installed in a building area, the work in the building area increases, and the work efficiency in the building area decreases.

  In consideration of the above facts, the present invention can secure a wide space beyond the unit boundary, reduce the required strength and rigidity of the building unit, and further improve the transportation efficiency from the factory to the building site. The object is to obtain a unit building that can achieve both improvement in work efficiency.

The connecting member is arranged in a state of being inserted into the slit so as to be relatively movable.

  According to a second aspect of the present invention, in the unit building according to the first aspect, the vertical width of the slit allows not only the relative movement in the horizontal direction but also the vertical movement of the connecting member with respect to the reinforcing beam. Thus, it is characterized by being set wider than the plate thickness of the connecting member.

  According to a third aspect of the present invention, in the unit building according to the first or second aspect, a pin to be assembled to the building unit is erected in advance on the connecting member, and the vertical width of the slit is A connecting member having a pin is set to a width allowing insertion.

The present invention according to claim 4 is a unit building composed of a plurality of building units, wherein the building unit is constituted by a temporary pillar in which a part of some of the building units is removable. Are arranged so that the temporary columns are adjacent to each other, and by forming a temporary column assembly removal portion from which the temporary columns are removed, a unit building in which a continuous wide space is formed is adjacent By connecting the building units to each other by a connecting member at a position near the temporary column assembly removal portion, the entire adjacent building unit is used as the first frame, and a predetermined gap formed between the beams of the adjacent building units. a reinforcing beam disposed in and spaced apart and the connecting member so as to pass through the provisional posts set removal vicinity, it is configured to include a post for supporting the reinforcing beam, wherein the first rack A second rack structure provided to the load is not transmitted between the body and dispersed with a load applied to the temporary column set removal portion and the first rack structure and the second rack structure It is characterized by supporting.

According to a ninth aspect of the present invention, in the unit building according to any one of the fourth to eighth aspects, the second frame includes the reinforcing beam and both end portions in the longitudinal direction of the reinforcing beam. It is formed in the gate type | mold provided with a pair of said support | pillar joined to and extended below.

  According to the first aspect of the present invention, some of the plurality of building units are provided with a detachable temporary pillar. A plurality of building units are arranged so that these temporary pillars are adjacent to each other. In this state, the reinforcing body is inserted and fixed so that the reinforcing beam passes through the vicinity of the temporary column assembly removal portion of the adjacent building unit that is arranged to face each other with a predetermined gap. Then, if a temporary pillar is removed from a temporary pillar assembly removal part, the unit building in which the continuous large space was formed will be constructed.

  Here, in this invention, it has the plate-shaped connection member which mutually connects adjacent building units in which the temporary pole group removal part is formed in the position near the temporary pole group removal part, and this connection member Is arranged in a state of being inserted in a slit formed in the reinforcing beam so as to be relatively movable so that a load is not transmitted between the building unit and the reinforcing body connected to each other by the connecting member. Accordingly, no force is transmitted between the reinforcement body and the connecting member, and the reinforcement body and the building unit support the overload separately. In other words, according to the present invention, the reinforcing body and the building are provided with a slit having a function of preventing the load from being transmitted between the building unit and the reinforcing body that are mutually connected by the connecting member. The structure is such that the overload is dispersed and supported by the unit. Therefore, the required strength and rigidity of the building unit can be reduced accordingly.

  Further, unlike the prior art, no load is transmitted from the reinforcing beam to the connecting member, so that the overload does not act vertically downward on the connecting member. Therefore, it is not necessary to provide a stiffener on the connecting member as in the prior art.

  According to the second aspect of the present invention, since the vertical width of the slit is set wider than the thickness of the connecting member, more specifically, not only the relative movement of the connecting member in the horizontal direction with respect to the reinforcing beam. Since the vertical width of the slit is set so as to allow relative movement in the vertical direction, the connecting member and the reinforcing beam do not interfere even if an assembling error of the connecting member occurs in the vertical direction.

  According to the third aspect of the present invention, the vertical width of the slit is set so that the connecting member in this state can be inserted even if the pin assembled to the building unit is erected in advance on the connecting member. There is no need to install the pins in the building area.

  According to the fourth aspect of the present invention, some of the plurality of building units are provided with temporary columns that can be removed. A plurality of building units are arranged so that these temporary pillars are adjacent to each other. In this state, the reinforcing body is inserted and fixed so that the reinforcing beam passes through the vicinity of the temporary column assembly removal portion of the adjacent building unit that is arranged to face each other with a predetermined gap. Then, if a temporary pillar is removed from a temporary pillar assembly removal part, the unit building in which the continuous large space was formed will be constructed.

Here, in the present invention, the adjacent building units are connected to each other by a connecting member in the vicinity of the temporary column assembly removal portion, so that the entire adjacent building unit is the first frame, and the adjacent building units A reinforcing beam disposed in a predetermined gap formed between the beams so as to pass through the vicinity of the provisional column assembly removal portion and spaced apart from the connecting member, and a support column supporting the reinforcing beam . a second rack structure provided to the load is not transmitted between the first rack structure to distribute load applied to the provisional posts set removal unit between the first rack structure and the second rack structure Therefore, the required strength and rigidity of the building unit can be reduced accordingly.

  Further, unlike the prior art, no load is transmitted from the reinforcing beam to the connecting member, so that the overload does not act vertically downward on the connecting member. Therefore, it is not necessary to provide a stiffener on the connecting member as in the prior art. For this reason, the enlargement of the load form of the reinforcing body and the stiffener mounting work in the building site, which are one of the problems of the prior art, do not occur.

  As described above, the unit building according to the first aspect of the present invention can secure a wide space exceeding the unit boundary, can reduce the necessary strength and rigidity of the building unit, and further, from the factory to the building site. It has an excellent effect that it is possible to achieve both improvement in transportation efficiency and improvement in work efficiency in a building site.

(Overall configuration of unit building according to this embodiment)
FIG. 4 is a perspective view showing the overall configuration of the unit building 10 according to the present embodiment. As shown in this figure, the unit building 10 includes a total of four building units 70. In addition, although the four building units 70 are arrange | positioned adjacently, in order to make drawing easy to see, the building units 70 adjacent in the digit direction are drawn apart.

  When the building units 70 are arranged, the building units 70 are installed on the foundation 16 so that temporary columns 72 (to be described later) included in the building units 70 are arranged in the center of the building. In the state in which the four building units 70 are arranged adjacent to each other, a gap 46 having the wife direction as a longitudinal direction is formed between two sets of opposed ceiling beams 44, and a gate-shaped reinforcing body is formed in the gap 46. 48 is inserted and fixed to the ceiling beam 44 and the foundation 16. Thereafter, as described above, by removing the four temporary pillars 72, the pillar-less portion 40 is formed on the first floor portion, and a wide space 50 exceeding the unit boundary is formed.

  The unit building 70 shown in FIG. 4 has basically the same structure as the unit building 10 shown in FIG. 3 (a structure having a ceiling frame 62 and a floor frame 64). Since the structure of the joint portion to which the upper and lower end portions of the 72 and the temporary column 72 are fixed is slightly different from that shown in FIG.

The temporary pillars 72 are temporarily fixed to the corners of the building unit 70 by matching the bolt insertion holes and tightening the bolts.

(Structure of reinforcement)
Next, the structure of a reinforcement body is demonstrated.

  FIG. 5 shows an exploded perspective view of the reinforcing body 100 together with the building unit 70. As shown in this figure, the reinforcing body 100 is formed in a gate shape, and has a flat plate-like reinforcing beam 102 disposed in the above-described gap 46 in an inserted state, and both longitudinal ends of the reinforcing beam 102. A pair of struts 104 joined to each other and extending downward are configured as main parts.

  Brackets 108 are fixed to both sides of the intermediate portion in the longitudinal direction of the reinforcing beam 102 at appropriate intervals. These brackets 108 are fastened to the ceiling beam 44 with bolts and nuts, so that the reinforcing beam 102 is fixed to the ceiling beam. 44 is fixed.

  Further, on the inner side surface of the upper end portion of the support column 104, an attachment member 110 for bolt-joining with the end portion in the longitudinal direction of the reinforcing beam 102 having the above configuration is provided. Furthermore, a rectangular flat mounting seat 112 for fixing to the foundation 16 or the like is provided at the lower end of the support column 104. From the bottom surface of the mounting seat 112, a tongue-shaped mounting piece 114 is formed so as to protrude downward. Correspondingly, a pair of fixed pieces 118 are disposed on the upper surface of the rectangular flat columnar support connecting member 116 placed on the upper surface of the foundation 16 with a gap approximately equal to the plate thickness of the mounting piece 114. Are erected in parallel. The mounting piece 114 is inserted into the gap between the pair of fixed pieces 118 and fastened with bolts and nuts, so that the lower end portion of the column 104 is coupled and supported by the column base 119.

(Main part configuration: relationship between connecting member (hereinafter referred to as “docking plate”) and reinforcing beam)
Next, the configuration of the docking plate 120 as a connecting member, which is a main part of the present embodiment, and the relationship between the docking plate 120 and the reinforcing beam 102 will be described with reference to FIGS.

  FIG. 8 is a plan view showing the assembled state of the reinforcing body 100 and the docking plate 120. As shown in this figure, the docking plate 120 is formed in a shape (substantially square) obtained by cutting off the four corners of a generally square plate, and includes a total of four substantially isosceles triangular connecting portions 122. As shown in FIG. 8, the connecting portion 122 of the docking plate 120 is used in this shape in the case where the four temporary pillars 72 gather, and in the case where the three temporary pillars 72 gather, one piece is used. In the case where the two temporary pillars 72 are gathered, they are cut into half and used.

  Each connection part 122 is provided corresponding to the part (ceiling joint part 76) in which the temporary pillar 72 was installed. A notch 124 is formed between adjacent connecting portions 122, and a through hole 126 is formed in the central portion. In addition, bolt insertion holes 128 are formed at the corners on the outer peripheral side of each connecting portion 122. Correspondingly, a bracket (not shown) in which a bolt insertion hole (not shown) of the same diameter is formed coaxially with the bolt insertion hole 128 is also arranged in the vicinity of the ceiling joint portion 76 of the building unit 70. . Then, the bolts are inserted into both bolt insertion holes 128 (one is not shown) and screwed into a nut (not shown), so that the ceiling joints 76 of adjacent building units 70 are connected to each other. It is the composition which is done. In addition, positioning pins 130 that are inserted into positioning holes (not shown) formed in the ceiling joint portion 76 are erected downward at the corners of the connecting portions 122 on the through hole 126 side.

  On the other hand, as shown in FIG. 9 and the like, a slit 132 into which the docking plate 120 can be inserted is formed in the middle portion of the reinforcing beam 102 in the longitudinal direction. The slit 132 is formed along the longitudinal direction of the reinforcing beam 102, and the slit width B is set to be slightly larger than the height h of the docking plate 120 in a state where the positioning pin 130 is erected. Therefore, the docking plate 120 can be inserted into the slit 132 with the positioning pins 130 standing upright.

  In addition, in the said structure, the four adjacent building units 70 are equivalent to the 1st frame in this invention of Claim 4, and the reinforcement body 100 is equivalent to the 2nd frame.

(Action / Effect)
Next, the operation and effect of this embodiment will be described.

  First, the overall operation will be described using the unit building 10 shown in FIGS. 4 and 5 as an example.

  The building unit 70 is transported from the factory to the building site with the provisional column 72, and in this state, it is sequentially installed on the foundation 16 using a crane. At this time, the building unit 70 is arranged so that the temporary pillars 72 gather on the center side of the building. In the state after installation, a predetermined gap 46 is formed between the ceiling beams 44 of the building units 70 adjacent in the girder direction. Next, the gate-shaped reinforcement body 100 is inserted into the gap 46 from any direction of the upper, lower and lateral directions and fixed. Specifically, a column support connecting member in which the reinforcing beams 102 of the reinforcing body 100 are fixed to two sets of facing ceiling beams 44 with a fastener via a bracket 108 and the lower end of the column 104 is installed on the foundation 16. 116 is fixed. After the reinforcing body 100 is fixed, the temporary pillars 72 are sequentially removed. Thereby, a wide space 50 (wide span) beyond the unit boundary is formed.

  By the way, although the four adjacent building units 70 described above are connected to each other by the docking plate 120 in the vicinity of the pillar-less portion 40, the docking plate 120 is disposed so as to straddle the gap 44. The docking plate 120 is in a positional relationship that interferes with the reinforcing beam 102. For this reason, a slit 132 through which the docking plate 120 can pass is formed in the middle portion of the reinforcing beam 102 in the longitudinal direction, and the docking plate 120 is inserted into the slit 132 so as to be relatively movable in the horizontal direction during assembly. In this state, the assembled state is obtained (see FIGS. 5 to 9).

  Here, in this embodiment, since the slit width B of the slit 132 is set sufficiently wider than the thickness of the docking plate 120, the docking plate 120 can be moved relative to the reinforcing beam 102 in the horizontal direction. As well as being able to move relative to the vertical direction. Therefore, in the state after the construction of the unit building 10, no force is transmitted between the reinforcing body 100 and the connecting member 120, and the reinforcing body 100 which is a portal-type reinforcing frame structure and the box-shaped building unit 70. And support the load from the upper floor separately. That is, the load applied to the pillar-less portion 40 from the upper floor is dispersed and supported by the four adjacent building units 70 as the first frame and the reinforcing body 100 as the second frame. Therefore, the required strength and rigidity of the building unit 70 can be reduced accordingly.

  Further, the docking plate 120 is inserted into the slit 132 of the reinforcing beam 102 so as to be relatively movable with a margin, and no load is transmitted from the reinforcing beam to the connecting member as in the prior art. A vertically downward load from the floor does not act. Therefore, in this embodiment, it is not necessary to set a reinforcing member such as a stiffener used in the prior art on the lower surface side of the docking plate 120. For this reason, the enlargement of the load form of the reinforcing body and the stiffener mounting work in the building site, which are one of the problems of the prior art, do not occur.

  When supplementing the load form of the reinforcing body using the drawings, FIG. 10 (A) shows the load form when transporting the reinforcing body 100 ′ in which the docking plate 120 ′ is integrated according to the conventional concept (when placed vertically). Is a side view of the reinforcing beam 102 ′ viewed from the longitudinal direction, and FIG. 10 (B) is a side view of the package when the same member is placed obliquely. In either case, the height of the package is H1 and H2, and a certain height is required. On the other hand, as shown in FIG. 10C, in the case of the present embodiment, the docking plate 120 can be completely separated from the reinforcing beam 102 and can be transported. H3 is much lower than H2. FIG. 11 shows a state in which the building unit 70 is loaded with the mount 138 placed on the loading platform 136 of the transport vehicle 134. According to this embodiment, the reinforcing body 100 can be accommodated within the range of the height H ′ of the mount 138 formed below the building unit 70 and transported together. Further, the reinforcing body 100 can be housed in the building unit 70 and transported.

  As described above, according to the present embodiment, a wide space 50 that exceeds the unit boundary can be secured, the required strength and rigidity of the building unit 70 can be reduced, and the transportation efficiency from the factory to the building site can be improved and the building can be constructed. It is possible to improve both work efficiency on the ground.

  In this embodiment, since the vertical width B of the slit 132 is set to be considerably wider than the thickness of the docking plate 120, more specifically, only the horizontal movement of the docking plate 120 relative to the reinforcing beam 102 is performed. In addition, since the vertical width B of the slit 132 is set so that relative movement in the vertical direction is allowed, the docking plate 120 can be reinforced even if an assembly error of the docking plate 120 occurs in the vertical direction. There will be no interference. Therefore, according to this embodiment, the non-connected state of the reinforcing beam 102 and the docking plate 120 can be favorably maintained. As a result, it is possible to reliably obtain the effect of dispersing and supporting the upper load between the reinforcing body 100 and the building unit 70.

  Further, in this embodiment, the vertical width of the slit 132 is such that the docking plate 120 in this state can be inserted even if the positioning pin 130 that prescribes the assembly position to the building unit 70 is erected on the docking plate 120 in advance. Since B is set, it is not necessary to perform the work of attaching the positioning pins 130 in the building area. Therefore, the work efficiency of the building site can be further improved.
