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 site. 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).
Japanese Patent No. 2866993

  However, according to the above prior art, there is a problem that the number of support columns is large and each support column is thick, so that the gap between the building units becomes large and it is not suitable for building in a narrow area. In order to solve this problem, it is conceivable to make the struts thin. However, if the struts are easily narrowed, another problem that deformation such as buckling easily occurs.

  In consideration of the above facts, the present invention has an object to obtain a unit building that can secure a wide space beyond the unit boundary and that is unlikely to undergo deformation such as buckling even if the struts of the reinforcing body are thinned.

  The present invention according to claim 1 is a unit building constituted by a plurality of building units, and a building unit constituted by a temporary pillar in which a part of some of the building units is removable. Is a unit building in which a large continuous space is formed by forming a plurality of temporary columns so that the temporary columns are adjacent to each other and forming a temporary column assembly removal part from which the temporary columns are removed, Reinforcement beams arranged between the beams passing through the vicinity of the temporary column assembly removal portion in the gap of the adjacent building units arranged to face each other with a gap, and the gap width of the gap while supporting the reinforcement beam And a support body that is formed to be thinner and spaced apart from the pillar, and is further mounted around the pillar to suppress or prevent the pillar from swinging. Re provided a stop means, it is characterized in that.

  According to a second aspect of the present invention, in the unit building according to the first aspect, the steadying means is fitted into a predetermined position in the longitudinal direction of the column from a direction perpendicular to the longitudinal direction, and is mounted. In the state after mounting, the spacer is characterized in that it is a spacer that holds the column in a non-contact state between the columns arranged opposite to each other.

In a state after mounting, a spacer that holds the column in a non-contact state between the columns arranged opposite to each other, and a column that is fitted between the columns arranged opposite to each other to be mounted and has a column at the fitting end. And a positioning member that positions the column by bringing the column into contact with each other.

  According to a fourth aspect of the present invention, in the unit building according to the third aspect, the struts are arranged so as to be offset in a direction orthogonal to the longitudinal direction of the reinforcing beams, and the struts and the reinforcing beams are offset. It is characterized by being connected to each other through brackets having a length corresponding to.

  According to a fifth aspect of the present invention, in the unit building according to the first aspect, the steadying means is fitted into a predetermined position in the longitudinal direction of the support column from a direction perpendicular to the longitudinal direction, and is mounted. In the state after mounting, the spacer holds the column in a non-contact state between the columns arranged opposite to each other, and between the other end and the column whose one end is fixed to the column and extends parallel to the column. And a positioning member that positions the column by holding the spacer.

  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 in the gap of the adjacent building units arranged facing 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. Note that the load acting on the temporary column assembly removal portion is supported by the reinforcing beam of the reinforcing body and transmitted to the mounting partner of the column through the column.

  Here, in the present invention, since the struts of the reinforcing body are formed narrower than the gap width of the gap, it is possible to install the strut using the gap even if the gap between the building units is narrow. . Therefore, it is suitable for constructing a unit building in a narrow area.

  On the other hand, when the struts are thinned in this way, the struts generally tend to buckle. However, in the present invention, since the anti-sway means is provided and mounted around the struts, it is possible to suppress or prevent the struts from swinging. can do.

(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 column 72 has angle-shaped attachment portions 74 at the upper end and the lower end thereof, and the ceiling joint portion 76 and the floor joint portion 78 have a concave shape in which the attachment portion 74 is accommodated correspondingly.

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.

  On the other hand, in the unit building 10 shown in FIG. 5, the reinforcing body 100 described below is assembled to the two-story second floor part, so that a column-less portion 40 is formed on the second floor part, and a wide space 50 exceeding the unit boundary is formed. It is the structure formed.

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

  As shown in FIG. 6, the reinforcing body 100 is configured in a gate shape, and has a flat plate-like reinforcing beam 102 that is disposed in the above-described gap 46 and both ends in the longitudinal direction of the reinforcing beam 102. And a pair of struts 104 joined downward and extending downward.

  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.

(Main part configuration: Configuration of steady rest means)
Next, the configuration of the steadying means will be described with reference to FIGS.

  FIG. 7 shows a plan layout of the unit building 10. The A line arrow part shown by this figure has shown the position where the column less part 40 is formed, and the B line arrow part has shown the position where a steadying means is applied.

  FIG. 8 is an enlarged plan view of the portion indicated by the arrow B in FIG. 7, and FIG. 9 is an enlarged perspective view of the main portion shown in FIG. Further, FIG. 10 is a drawing of the assembled state of the reinforcing body 100 as viewed from the side.

  As shown in these drawings, the reinforcing beam 102 of the reinforcing body 100 described above is arranged in an inserted state in the gap 46 between the ceiling large beams 44 of adjacent building units 70. And the support | pillar 104 of this reinforcement body 100 is arrange | positioned in the insertion state in the clearance gap 47 between a pair of pillar 32 arrange | positioned facing. Incidentally, the gap 47 between the columns 32 is arranged on the same straight line as the gap 46 between the ceiling beams 44 and communicates with each other. However, the gap 47 has a smaller gap width than the gap 46, and It is formed even thinner.

  Therefore, in this embodiment, as shown in FIG. 9, a spacer 120 that is composed of a base portion 120 </ b> A and both side portions 120 </ b> B and is formed in a U shape in plan view is used as the steadying means. The material of the spacer 120 is plywood, wood, resin, etc., but the material is not particularly limited. Preferably, the spacer 120 has a laminated structure as shown in the figure, and the thickness can be adjusted by peeling one by one in accordance with the gap between the column 32 and the column 104. What is easy is preferable.

  The opening width of the opening portion 122 of the spacer 120 is set to be substantially the same as the width of the support column 104. When assembling, the support member 104 is fitted in the opening portion 122 of the spacer 120, and the 120 bases 120 </ b> A are fixed to the side surface of the column 104. In this state, the spacer 120 is inserted into the gap 47 between the opposing columns 32. The mounting direction of the spacer 120 is a direction from the inside of the building to the outside of the building. Further, in a state where the spacer 120 is mounted in the gap 47 between the opposing pillars 32, both side portions 120B of the spacer 120 are interposed between the pillars 104 and the pillars 32 that are square pipes, and the pillars 104 are separated from the pillars 32. It is designed to be held apart. In addition, as shown in FIG. 10, in this embodiment, the spacers 120 are mounted in the vicinity of the upper end portion and the intermediate portion of the support column 104. However, the spacers 120 may be installed in three or more locations. The effect is obtained.

(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, a gate-shaped reinforcing body 48 (reinforcing body 100 in FIG. 5) is inserted into the gap 46 from any direction of the upper, lower and lateral directions and fixed. Specifically, the reinforcing beams of the reinforcing bodies 48 and 100 are fixed to the two sets of facing ceiling beams 44 with fasteners, and the lower ends of the columns 104 connect the columns 32 adjacent to each other on the foundation 16 or in the spar direction. It is fixed to the member. After the reinforcing bodies 48 and 100 are fixed, the temporary pillar 72 is sequentially removed. Thereby, a wide space 50 (wide span) beyond the unit boundary is formed. In the case of FIG. 4, a wide space 50 is formed on the first floor portion, and in the case of FIG. 5, a wide space 50 is formed on the second floor portion.

  In the unit building 10 constructed as described above, the load applied to the pillar-less portion 40 is distributed to the four adjacent building units 70 from the ceiling beam 44 of the building unit 70 connected to the reinforcing bodies 48 and 100. Is transmitted. In this way, most of the load flows to the building unit 70 side and is transmitted to the foundation 16 to be supported. A part of the load is transmitted and supported from the reinforcing beams 102 of the reinforcing bodies 48 and 100 to a member connecting the foundations 16 or the columns 32 adjacent to each other in the spar direction through the pair of columns 104.

  Here, in this embodiment, since the column 104 of the reinforcing body 100 described above is formed to be narrower than the gap width of the gap 47 between the pillars 32 on the extension of the gap 46, the gap between the adjacent building units 70. Even if 47 is narrow, it is possible to install the column 104 using the gap 47. Therefore, it is suitable for constructing the unit building 10 in a narrow area.

  On the other hand, when the struts 104 of the reinforcing body 100 are thinned in this way, the struts 104 are generally easily buckled. However, in this embodiment, the spacers 120 are mounted around the struts 104 between the pillars 32. Since the support column 104 is placed in the gap 47, it is possible to suppress or prevent the support column 104 from swinging in a tilting direction (a direction intersecting the longitudinal direction of the support column 104).

  As described above, according to the unit building 10 according to the present embodiment, a wide space 50 that exceeds the unit boundary can be secured, and even if the column 104 of the reinforcing body 100 is thinned, deformation such as buckling hardly occurs.

  Further, according to the unit building 10 according to the present embodiment, the steadying means is configured by the spacer 120 formed in a U shape in plan view, and thus is perpendicular to the longitudinal direction at a predetermined position in the longitudinal direction of the column 104. The spacer 120 can be fitted to the support column 104 from the direction to be in the mounted state. In the state after mounting, both side portions 120B of the spacer 120 are interposed between the opposing surfaces of the column 32 and the column 104, so that the column 104 can be held away from the column 32 (in a non-contact state). . Therefore, it is convenient and preferable when a column 104 that is narrower than the gap width of the gap 47 is placed in the gap 47 between the opposing columns 32 of the adjacent building unit 70.

〔variation〕
Next, some variations will be outlined.

<Application example 1>
FIG. 11 shows a plan layout of the unit building 10. The unit building 10 shown in FIG. 11 (A) is an example in which three building units 70 are adjacent to each other and a wide-span building unit 70 ′ having a larger size is arranged orthogonally. In addition, the unit building 10 shown in FIG. 11B is an example in which one building unit 70 is replaced with two half-sized building units 70 ″. In these cases, the pillar 32 is replaced. Since the ceiling girder 44 is arranged adjacent to the above, a steadying means different from the above is required.

  Therefore, in this embodiment, as shown in FIGS. 12 and 13, in addition to the spacer 120 described above, a steady bracket 130 as a positioning member is used. The steady rest bracket 130 has a hat shape in plan view, and includes an intermediate portion 130A protruding in a convex shape and both end portions 130B bent in directions away from the base end portion of the intermediate portion 130A. ing. The dimension in the width direction of the intermediate portion 130 </ b> A substantially matches the gap size of the gap 47 between the columns 32 arranged to face each other, and the intermediate portion 130 </ b> A can be fitted into the gap 47. Further, both end portions 130 </ b> B are fixed to the pillars 32 with screws 132.

  The steady bracket 130 is assembled from the same direction as the spacer 120. Further, the steady rest bracket 130 is attached to be spaced below the spacer 120 when attached.

  Also, as shown in FIG. 12, in this embodiment, the reinforcing beam 102 passes through the center of the gap 46 between the adjacent ceiling beams 42 ′ and 44, and the gap 47 between the columns 32 is adjacent. ′ And 44 are not on the same straight line but are orthogonal to the gap 46. Therefore, the bracket 134 is fixed to the upper end portion of the column 104, and the bracket 134 and the longitudinal end portion 102 </ b> A of the reinforcing beam 102 are connected to each other. It is fixed with bolts 136 and nuts 138. The bracket 134 is an element grasped as a “connecting member” in a broad sense.

(Action / Effect)
According to the above configuration, the U-shaped spacer 120 is first fitted to the support column 104 of the reinforcing body 100 in a plan view and fixed with the screw 124. Next, the column 104 in this state is inserted into the gap 47 between the columns 32 arranged to face each other. Thereafter, the steady bracket 130 having a hat-shaped cross section is attached from the direction opposite to the insertion direction of the support column 104. Specifically, after the intermediate portion 130 </ b> A of the steady bracket 130 is inserted into the gap 47 between the columns 32, both end portions 130 </ b> B are fixed to the columns 32 with screws 132. As a result, the position in the gap 47 of the intermediate portion 130A of the steady bracket 130 is defined, so that the column 104 (gap 47) of the reinforcing body 100 is brought into contact with the intermediate portion 130A in a surface contact state. The column 104 is positioned by correcting the position in the longitudinal direction. As a result, according to this embodiment, the column 104 can be easily positioned, and as a result, workability during construction can be improved.

  Further, in this embodiment, the column 104 is offset and arranged in a direction orthogonal to the longitudinal direction of the reinforcing beam 102, and the reinforcing beam 102 is interposed via a bracket 134 having a length corresponding to the offset amount of both. In other words, by setting the bracket 134, it is possible to place the column 104 between the columns 32 arranged opposite to each other. It can be avoided that the column 104 protrudes from the column 32 in a case where the column is asymmetrical. As a result, according to this embodiment, it is possible to avoid the support column 104 from interfering with the indoor module, and thus it is possible to prevent the indoor space from being narrowed.

<Application example 2>
FIG. 14 shows a plan layout of two types of unit buildings 10. The unit building 10 shown in FIG. 14A has a configuration equivalent to that of the above-described configuration shown in FIG. This is an example in the case where it is necessary to store the support column 104. On the other hand, in the unit building 10 shown in Fig. 14 (B), two half-size building units 70 "are further added to the two building units 70. This is an example in which a wide-span building unit 70 ′ having a size larger than that of the building unit 70 is arranged orthogonally in a plane arrangement of three building units 70. Note that this example has an equivalent configuration in which the building unit 70 on the upper and lower sides of the unit building 10 shown in FIG. 11A described above is replaced with two half-sized building units 70 ″. In this example, the two pillars 32 are arranged facing each other so as to face the building unit 70 'arranged orthogonally, and the pillar-less portions 40 are set at two places on the same straight line. Since the two reinforcing bodies 100 are continuously arranged on the same straight line, the column 104 is arranged adjacent to each of the two opposing columns 32. Therefore, in these cases Since the hat-shaped steady-state bracket 130 cannot be used in a plan view, a steady-state means different from the application example 1 is required.

  Therefore, in this embodiment, as shown in FIGS. 15 and 16, in addition to the spacer 120 described above, another shape of the steady-state bracket 140 as a positioning member is used. The steady rest bracket 140 is formed in an L shape in a plan view, and includes a fixing portion 140A and a holding portion 140B. The base of the fixing portion 140 </ b> A is fixed to the pillar 32 with a screw 142. In a state where the fixing portion 140A is fixed to the column 32 with the screws 142, a predetermined gap 146 is formed between the side surface of the column 32 and the holding portion 140B. And the support | pillar 104 with which the spacer 120 was mounted | worn in this clearance gap 146 is the structure hold | maintained in an insertion state. In FIG. 15, the outer wall 148 is arranged in parallel to the ceiling beams 42 and 44.

(Action / Effect)
According to the above configuration, the U-shaped spacer 120 is first fitted to the support column 104 of the reinforcing body 100 in a plan view and fixed with the screw 124. Next, the column 104 in this state is brought into contact with the side surface of the column 32. Thereafter, the fixing portion 140A is brought into contact with the side surface of the column 32 so that the spacer 120 is hooked by the holding portion 140B of the steady-state bracket 140 having an L-shaped cross section, and is fixed by the screw 142. Since the attachment point of the screw 142 is determined in advance on the column 32 side, when the fixing portion 140A of the steady bracket 140 is fixed to the column 32, the distance of the gap 146 between the holding portion 140B and the side surface of the column 32 is determined. Therefore, the column 104 is also positioned. That is, the column 104 is positioned by correcting the assembly position of the column 104 when the steady rest bracket 140 is attached. As a result, according to this embodiment, the column 104 can be easily positioned, and as a result, workability during construction can be improved.

  Further, in this embodiment, even when the cross section hat-shaped steady rest bracket 130 cannot be used, by using the L-shaped steady rest bracket 140 in a plan view in a cantilever support structure, Even in a complicated place such as 144, the column 104 can be stably placed next to the column 32. Therefore, it can avoid that the support | pillar 104 interferes with the outer wall 148 and an indoor module. Therefore, there is no concern that the fitting of the entrance corner 144 becomes worse, the sealing performance of the joint of the outer wall 148 is adversely affected, and the indoor space is not narrowed.
