Abstract

(57) [Summary] [Purpose] To reduce the cost of structures. [Structure] In a joint structure of a structure that joins a sub shed unit 12 and a sub shed roof unit 13, a guide joint bolt 17 is erected on a gable beam 15 and a girder beam 16 of the sub shed unit, The truss lower beam 18 and the eaves beam 19 of the roof unit are formed with through holes 20 through which the guide joint bolts can be inserted, and the guide joint bolts are inserted through the through holes to make the sub roof roof unit into the sub roof unit. After positioning, the nut 23 is screwed into the guide joint bolt to join both units.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure of structures such as building units, building units and roof units.

[0002]

2. Description of the Related Art When joining building units to each other or a building unit and a roof unit, one of them is positioned with respect to the other and then they are fastened and fixed with bolts and nuts.

For example, in the roof unit disclosed in Japanese Patent Application Laid-Open No. 2-171451, as shown in FIG. 3, a guide pin 2 is erected on a roof beam 1 of a building unit. The roof unit is positioned with respect to the building unit by being inserted into the guide pin holes 4 formed in the roof frame 3. Then, the joint bolt 6 is inserted into the bolt insertion hole 5 formed in the roof beam 1 of the building unit and the roof frame 3 of the roof unit, and the washer 7 is inserted.
The nut 8 is screwed into the joint bolt 6 via the to fasten the roof beam 1 and the roof frame 3 to join the roof unit to the building unit.

[0004]

However, in the above-mentioned prior art, the guide pin 2 has only a positioning function, and even if it is necessary at the time of construction of the roof unit, the building unit and the roof unit by the joint bolts 6 and nuts 8 After the joining is completed, it is buried and does not function at all, and it must be said that it is wasteful in terms of cost.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a joint structure for a structure which can reduce the cost of the structure.

[0006]

According to a first aspect of the present invention, there is provided a joint structure for joining a structure and another structure, wherein a guide joint bolt is provided at a joint portion of the one structure. Upright, forming an insertion hole through which the guide joint bolt can be inserted in the joint portion of the other structure, and inserting the guide joint bolt into the insertion hole to separate the other structure from the one described above. Positioned on the structure of
A nut is screwed onto the guide joint bolt to join the two structures.

[0007]

The invention described in claim 1 has the following effects. The guide joint bolt erected on one structure has the function of inserting the other structure into the insertion hole and positioning the other structure, and the function of joining both structures by screwing the nut. Therefore, the positioning pin is not required in either one of the one structure and the other structure, and the positioning pin hole is not required in the other of the one structure or the other structure. Therefore, the cost of the structure can be reduced.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing a joined state of a sub shed unit and a sub shed roof unit to which an embodiment of a structure joining structure according to the present invention is applied. FIG. 2 is an exploded perspective view of the joint portion of FIG.

In the unit building 10 shown in FIG. 1, a sub-shelf unit 12 as a structure is installed adjacent to a building unit 11 on the first floor.
The sub-shelf roof unit 13 as a structure is installed on the top. The building unit 11 on the second floor is installed on the building unit 11, and the roof unit 14 is installed on the building unit 11 on the second floor.

FIG. 2 shows the joint between the sub-shelf unit 12 and the sub-shelf roof unit 13. The girder beam 15 and the girder beam 16 as the joints of the sub-shelf unit 12 are connected to the guide joint bolts 17. Is fixed upright.
On the other hand, an insertion hole 20 is formed in the truss lower beam 18 and the eave beam 19 as a joint portion of the sub lower roof unit 13, and the guide joint bolt 17 can be inserted into the insertion hole 20. Reference numeral 21 in FIG. 2 indicates a truss upper beam.

When installing the sub shed roof unit 13 on the sub shed roof unit 12, the sub shed roof unit 13 is lifted by a crane or the like, and the truss lower beams 18 and eaves beams 19 in the sub shed roof unit 13 are inserted. The sub joint roof unit 13 is positioned by inserting the guide joint bolts 17 of the sub roof unit 12 into the holes 20. After that, the nut 23 is screwed into the guide joint bolt 17 via the washer 22, and the truss lower beam 18 and the eaves beam 19 of the sub shed roof unit 13 are attached to the gable beam 15 and the girder beam 16 of the sub shed roof unit 12. Each of them is joined together to connect the sub shed roof unit 13 to the sub shed unit 12
To join.

According to the above embodiment, the sub shed unit 1
The guide joint bolts 17 erected on the gable beam 15 and the girder beam 16 of No. 2 are inserted into the respective through holes 20 of the truss lower beam 18 and the eave beam 19 of the sub shed roof unit 13, and the sub shed is With the function of positioning the roof unit 13 and the screwing of the nut 23, the sub shed unit 12
Also, since it has a function of joining the sub shed roof unit 13, the positioning pin 2 (FIG. 3) is not required for either the sub shed unit 12 or the sub shed roof unit 13, and the sub shed unit 12 or The guide pin hole 4 (FIG. 3) for the positioning pin is not required on the other side of the sub lower roof unit 13. Therefore, the costs of the sub-loft unit 12 and the sub-loof roof unit 13 can be reduced.

The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific structure of the present invention is not limited to this embodiment, and changes in design within the scope not departing from the gist of the present invention can be made. Even if it exists, it is included in the present invention. For example, the present invention may be applied to a joint between building units on the upper floor and a lower floor, or may be applied to a joint such as a wall.

[0014]

As described above, according to the structure joint structure of the present invention, the cost of the structure can be reduced.
