Description

  The present invention is a unit house assembly structure that can be transported and installed on the site for each completed unit when building, for example, a house, an office, a store, a warehouse, etc. as a permanent or temporary construction, and used for this. The present invention relates to an anchor bolt error adjusting bracket and an installation method of a unit house assembly structure using the anchor bolt error adjusting bracket.

  Conventionally, a unit house sales company mainly provides, for example, a model house, a temporary house, a temporary store, and the like, which are installed only for a predetermined period, and is mainly used for rental at a construction site. When manufacturing such a unit house, first, a lightweight steel frame is joined by welding to create a rectangular frame structure, and the steel frame of the rectangular frame structure has various building materials such as outer walls, inner walls, sashes, and the like. Install electrical wiring and purification drainage equipment. The main work of manufacturing such a rectangular parallelepiped frame structure is performed at the factory, and each completed unit is transported to the site and installed.

  When such a unit house is used as a temporary store such as a mini shop, storeroom, or field office, an installation confirmation application is unnecessary because the installation area is limited to a building of less than 10 square meters. On the other hand, when the unit house is used for a home, for example, a house, an office, a store, a warehouse, etc., it is necessary to apply for a building confirmation after completing an appropriate structural calculation. In this way, there are a lot of housing specialists who build a permanent house by the unit method.

  In addition, there are cases where the unit is used as a single unit for a home and there are cases where two or more units are connected and used. For example, the size when using one unit can be loaded on a truck and It is limited to a size that does not hinder the operation of the vehicle, for example, within a width of 2.4 m, a length of 9 m, and a height of 3 m.

Furthermore, ordinary buildings that are not unit houses in the past have columns for anchor bolts embedded on concrete foundations, and beams are connected to the columns with bolts. Or, it is impossible to perform construction exactly the same as the architectural design drawing due to the superiority or inferiority of the construction worker's technology. For example, even in the welding of steel frames, some deviation is likely to occur due to the properties of iron and heat during welding. However, if there is an allowable error in the building product and it is within the allowable error range compared to the architectural design drawing, the column standing with respect to the anchor bolt and the beam bolt with respect to the column should be It is considered that adjustments may be made as appropriate at the connection stage.
None

  However, when the conventional unit house is used for a home, for example, a house, an office, a store, a warehouse, etc., in addition to using the above-mentioned rectangular parallelepiped frame structure as a single unit, a plurality of units of the rectangular parallelepiped frame structure are used. However, since the shape of the rectangular frame structure itself cannot be changed arbitrarily, the pattern of the assembly method by the unit itself is limited to a very small number. The reality is that the expression of architectural space is poor.

  Moreover, if the normal building which is not a unit house in the past is within the allowable error range compared with the architectural design drawing, the above-described column standing with respect to the anchor bolt and the beam bolt with respect to the column are used. It is assumed that adjustments may be made as appropriate at the connection stage. However, in the case of a unit house, it is produced in a rectangular parallelepiped frame structure with high accuracy by welding work in a manufacturing factory, so that the finish position of the anchor bolt embedded on the foundation is not determined with high accuracy. It often happens that the anchor bolt and the hole opened in the steel frame do not match. Moreover, in the conventional unit house, the roof panel once attached has a structure that cannot be detached, so that it is difficult to change or add units.

  For example, holes are drilled in the four corners of the base beam part built into the rectangular shape of the unit house, and anchor bolts planted in the four corners on the rectangular foundation by placing concrete corresponding to the base beam are passed through these holes. In such a case, the anchor bolt may not be inserted into at least one of these holes, so that the workability at the time of assembling the unit is inferior. It should be noted that the same disadvantages as described above also occur at the joint portion between the base beam portion and the column portion of the unit house, or at the joint portion between the beam portion of one unit house and the pillar portion of the other unit house combined therewith.

  Therefore, the present invention was created in view of the existing circumstances as described above, and in the case of using a unit house as a permanent or temporary housing such as a house, office, store, warehouse, etc. The pattern of how to assemble can be diversified, and the expression of the architectural space can be diversified by making it possible to change the way of assembling the units and add units, and there are also anchor bolts and holes drilled in the steel frame The unit house assembly structure and the anchor bolt error adjustment metal fittings used in this unit are designed to improve the workability when assembling and installing the unit by eliminating the negative effects of non-conformity, and to easily reassemble and add units. And it aims at providing the installation method of the unit house assembly structure which uses an anchor bolt error adjustment metal fitting.

  In order to solve the above-described problems, the unit house assembly structure according to the present invention is a unit house assembly structure that can be transported and installed on the site for each completed unit, and has a rectangular parallelepiped framework structure. A regular unit, a half unit having a cubic frame structure, an eye panel unit having a rectangular frame structure, and an L panel unit in which the eye panel units are connected in an L shape are used as components of the unit house assembly structure.

  Moreover, the roof panel which can be separated with respect to each unit as the said component can be included.

  The component may include a composite panel unit in which an eye panel unit is connected to an L panel unit.

  The component may include a column unit having a columnar frame structure.

  In the anchor bolt error adjusting bracket used in the unit house assembly structure according to the present invention, a seat surface portion having a hole through which an anchor bolt planted on the foundation can be inserted with an arbitrary backlash is provided. An insertion cylinder having a screw hole so that it can be inserted into the rectangular cylindrical column portion of the unit house with an arbitrary gap and is fixed by screwing a bolt through a hole formed in a side surface of the column portion. It has become a part.

  In the installation method of the unit house assembly structure according to the present invention, a bottomed mass-shaped anchor in which an anchor bolt planted on a foundation is drilled so as to be slightly larger than the outer diameter of the anchor bolt. Insert the bolt error adjusting bracket into the hole on the seat surface, position the seat surface while sliding the anchor bolt error adjusting bracket itself horizontally on the foundation with respect to the anchor bolt position, and then screw the nut into the anchor bolt to fix the anchor bolt error. The adjustment bracket is fastened and fixed on the foundation, and the square-tubular column of the unit house formed by combining the regular unit, half unit, eye panel unit, and L panel unit, Insert the anchor bolt error adjustment bracket insertion cylinder, and insert the anchor bolt error adjustment bracket insertion cylinder from the side of the column. It has become a thing that screwed the bolt over.

  According to the present invention, when a unit house is used as a permanent or temporary housing such as a house, an office, a store, a warehouse, etc., it is possible to diversify the pattern of how to assemble by unit, By adding units, it is possible to diversify the expression of the building space, and workability when assembling and installing units is eliminated by eliminating the conventional ill effects that anchor bolts and holes drilled in steel frames do not match. In addition, the unit can be reassembled and added easily and quickly.

  That is, a unit house assembly structure that allows each completed unit to be transported and installed on site, a regular unit having a rectangular parallelepiped frame structure, a half unit having a cubic frame structure, an eye panel unit having a rectangular frame structure, Since each of the L panel units in which the eye panel units are connected in an L shape is a component of the unit house assembly structure 1, the expression of the building space can be easily diversified. In particular, by using an eye panel unit or an L panel unit as an auxiliary, it has become possible to easily assemble a method that was impossible in the past.

  In addition, since the roof panel that can be separated from each unit is included, the unit can be easily reassembled and added, and the unit house itself can be recycled.

  Further, since the component includes a composite panel unit in which an eye panel unit is connected to an L panel unit, workability at the time of assembly and installation of each unit is further improved.

  Furthermore, since the component includes a column unit having a columnar frame structure, diversification of the building space is further improved.

  In the anchor bolt error adjusting bracket used in the unit house assembly structure according to the present invention, a seat surface portion having a hole through which an anchor bolt planted on the foundation can be inserted with an arbitrary backlash is provided. An insertion cylinder having a screw hole so that it can be inserted into the rectangular cylindrical column portion of the unit house with an arbitrary gap and is fixed by screwing a bolt through a hole formed in a side surface of the column portion. Anchor bolt error adjustment bracket that can eliminate the conventional bad effect that the anchor bolt does not match the hole drilled in the steel frame and improve the workability when assembling and installing each unit. Can be manufactured at low cost.

  Moreover, since the error adjusting bracket is easy to connect and disassemble units, the unit can be easily reused, and the added value of the unit itself is increased. Further, the error adjusting bracket exhibits sufficient resistance against not only the axial force generated at the connecting portion, but also the horizontal force and pulling force generated during wind pressure and earthquake.

  In the installation method of the unit house assembly structure according to the present invention, a bottomed mass-shaped anchor in which an anchor bolt planted on a foundation is drilled so as to be slightly larger than the outer diameter of the anchor bolt. Insert the bolt error adjusting bracket into the hole on the seat surface, position the seat surface while sliding the anchor bolt error adjusting bracket itself horizontally on the foundation with respect to the anchor bolt position, and then screw the nut into the anchor bolt to fix the anchor bolt error. The adjustment bracket is fastened and fixed on the foundation, and the square-tubular column of the unit house formed by combining the regular unit, half unit, eye panel unit, and L panel unit, Insert the anchor bolt error adjustment bracket insertion cylinder, and insert the anchor bolt error adjustment bracket insertion cylinder from the side of the column. Since it is assumed that threaded bolts over a hole drilled in the anchor bolt and the steel frame can be eliminated conventional drawback that do not match, it is possible to improve workability in assembling the installation of the units.

  In addition, this method is not a single unit continuous as in the prior art, and units can be connected and stacked in various ways. For example, in the conventional unit method, only the same plane can be stacked on both the upper and lower floors, but in this unit method, the upper and lower units are shifted, and the units are stacked perpendicularly, that is, the regular unit is shifted by a half unit, In addition, it can be installed in a stack in the orthogonal direction, enabling flexible planning when various floor plans such as houses are required.

  The best mode for carrying out the present invention will be described below with reference to the drawings. Reference numeral 1 shown in the drawings denotes a unit house assembly that can be transported and installed on the site for each completed unit. The unit house assembly structure 1 includes a regular unit 2 having a rectangular parallelepiped frame structure, a half unit 3 having a cubic frame structure, an eye panel unit 4 having a rectangular frame structure, and the eye panel unit 4 connected in an L shape. Four of the L panel units 5 are components of the unit house assembly structure 1.

  That is, as shown in FIG. 1A, the regular unit 2 has, for example, 4 m of 2.4 m in length on both upper and lower sides via square columnar pillars 6 with 4 corners of length of 2.65 m, for example. A rectangular frame structure is formed by assembling and welding the beam members 7 of a U-shaped steel frame and four U-shaped steel frames having a length of 4.8 m in a rectangular shape.

  Moreover, as shown in FIG.1 (b), the half unit 3 is 8 m of 2.4 m in length, for example on both sides up and down via the prismatic columnar material 6 of the four corners of 2.65 m in length. A beam frame 7 made of a U-shaped steel frame is assembled in a rectangular shape and welded to form a cubic frame structure.

  Further, as shown in FIG. 1 (c), the eye panel unit 4 has a length of 2.4 m, for example, on both upper and lower sides via left and right prismatic columnar members 6 having a length of 2.65 m, for example. A rectangular frame structure is formed by incorporating and welding beam members 7 each having two U-shaped steel frames.

  In addition, as shown in FIG. 1D, the L panel unit 5 has a length of, for example, 2.4 m on both upper and lower sides via three prismatic columnar members 6 having a length of, for example, 2.65 m. Each of the two beam members 7 of the four U-shaped steel frames is assembled in an L shape and welded to form a rectangular frame structure.

  In addition to these components, a composite panel unit 8 in which the eye panel unit 4 is connected to the L panel unit 5 may be used. For example, as shown in FIG. 2 (e), a long eye panel unit 4 in which the short eye panel unit 4 is connected in an L shape in opposite directions on both sides can be used. ), Two eye panel units 4 of the same size can be used on both sides of the central eye panel unit 4 so as to be opposite to each other and connected in an L shape.

  Further, as shown in FIG. 2 (g), an eye panel unit 4 whose one end can be opened may be used. Furthermore, as shown in FIG. 2 (h), a cylindrical body is obtained by incorporating and welding beam members 7 each having an annular U-shaped steel frame on the upper and lower sides via a pair of left and right prismatic columnar members 6 respectively. A columnar unit 9 having a skeleton structure may be used.

  Then, when assembling each of the above-mentioned units on site, as shown in FIG. 3, for example, the regular unit 2 and the eye panel unit 4 are spaced apart from each other, and the other regular unit 2 and half unit 3 are respectively placed on these units. By connecting the two, it is possible to express a two-story architectural space.

  When assembling each of these units on site, as shown in FIG. 4, the joint portion (the portion A in FIG. 4) between the anchor bolt Q position on the foundation P and the column material 6 of the regular unit 2 on the lower side. ), The joint portion (B portion in FIG. 4) between the column material 6 of the lower regular unit 2 and the column material 6 of the upper half unit 3, the beam material 7 of the lower regular unit 2 and the upper regular unit. 2. A bottomed-mass-shaped anchor bolt error adjusting fitting 10 is used at a joint portion (C portion in FIG. 4) with each column member 6 of each of the half units 3.

  That is, as shown in FIG. 6, the anchor bolt error adjusting fitting 10 is formed as a bottomed mass that forms a seating surface portion 12 by closing one end opening side of the rectangular tube-shaped insertion tube portion 11 with a rectangular plate surface material. A hole 13 slightly larger than the outer diameter of the anchor bolt Q planted on the foundation P is drilled by, for example, a drilling drill or the like, and the insertion tube portions 11 are adjacent to each other in the approximate center of the seat surface portion 12. A screw hole 14 is screwed in the approximate center of the two side surfaces.

  And when installing and fixing a unit house on the foundation P, in the junction part (A part in FIG. 4) of the anchor bolt Q position on the foundation P and the pillar material 6 of the lower regular unit 2, FIG. Alternatively, as shown in FIG. 6, the anchor bolt Q on the foundation P is inserted into the hole 13 of the seat surface portion 12 of the anchor bolt error adjustment fitting 10, and the anchor bolt error adjustment fitting 10 itself is located with respect to the anchor bolt Q position. While sliding horizontally on P, the seat surface 12 is positioned so that the hole 6A formed in the side surface of the columnar column 6 into which the insertion tube 11 is inserted and the screw hole 14 of the insertion tube 11 are aligned with each other. After that, the anchor bolt error adjusting fitting 10 is fastened and fixed on the foundation P by screwing the nut 15 into the anchor bolt Q.

  Thus, as shown in FIG. 9, one of the plurality of anchor bolts Q planted on the foundation P is deviated from the specified marker line M and shifted by Δe vertically and horizontally within an allowable error range, for example. Even so, the anchor bolt error adjusting fitting 10 itself is slid laterally on the foundation P with respect to the anchor bolt Q position, so that a hole 6A formed on the side surface of the columnar columnar column 6 into which the insertion tube portion 11 is inserted. And the screw hole 14 of the insertion cylinder portion 11 can be made to coincide with each other, whereby the insertion cylinder portion 11 of the anchor bolt error adjusting fitting 10 is inserted into the square cylindrical column material 6 of each unit, and then the column The bolt 16 can be accurately screwed into the hole 6A on the side surface of the material 6 and the screw hole 14 of the insertion tube portion 11 of the anchor bolt error adjusting fitting 10. In short, the displacement of the anchor bolt Q position from the marker line M is adjusted by the anchor bolt error adjustment fitting 10.

  Moreover, in the junction part (B section in FIG. 4) of the column material 6 of the lower regular unit 2 and the column material 6 of the upper half unit 3, as shown in FIG. 7, the lower regular unit 2 The upper end of the square hole of the column member 6 is closed, and the seat surface portion 12 of the anchor bolt error adjusting fitting 10 is fixed through a bolt 17 planted with the screw portion facing upward at the center. At this time, even if the position of the bolt 17 is shifted from the center of the column member 6, by sliding the anchor bolt error adjustment fitting 10 laterally, the hole 6 </ b> A on the side surface of the column member 6 and the insertion cylinder portion of the anchor bolt error adjustment fitting 10 are used. The position of the seating surface portion 12 is appropriately adjusted so that the bolt 16 can be accurately screwed into the 11 screw holes 14.

  Further, in the joint portion (C portion in FIG. 4) between the beam member 7 of the lower regular unit 2 and the column member 6 of each of the upper regular unit 2 and the half unit 3, as shown in FIG. A pair of left and right bolts 17 are planted on the beam member 7 of the regular unit 2 on the side with the threaded portion facing upward, and the bolts 17 are inserted into the holes 13 of the seating surface portion 12 of the anchor bolt error adjustment fitting 10. And fix with the nut 15. Then, after inserting the column members 6 of the regular unit 2 and the half unit 3 into the insertion tube portion 11 of the anchor bolt error adjusting bracket 10 in a state of being adjacent to each other, the hole 6A on the side surface of the column member 6 and the anchor bolt error adjustment A bolt 16 is screwed into the screw hole 14 of the insertion tube portion 11 of the metal fitting 10. At this time, even if the position of the bolt 17 is misaligned, the anchor bolt error adjustment fitting 10 is slid laterally, thereby causing the hole 6A on the side surface of the column member 6 and the screw hole 14 of the insertion tube portion 11 of the anchor bolt error adjustment fitting 10 to The position of the seat surface portion 12 is adjusted as appropriate so that the bolt 16 can be screwed in accurately.

  In addition, as shown in FIG. 10, various types of roof panels 18 such as a flat roof, a tanner, a firewood, a cracker, a hojo, and a seam can be separated from each unit. is there. In this way, for example, the flat roof-shaped roof panel 18 placed on each of the regular units 2 of the two-row building, for example, is once removed, and then the other regular units 2 are connected to each of the regular units 2. It is possible to easily change to a two-story structure by placing the roof panel 18 on the upper regular units 2 again.

  Next, the installation method of the unit house assembly structure 1 for the best configuration configured as described above will be described.
