Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beam height adjusting jig for adjusting the beam height between adjacent building units in a unit type building, and an adjacent building using the beam height adjusting jig. The present invention relates to a method of adjusting a beam height position between units.

[0002]

2. Description of the Related Art Conventionally, as a kind of prefabricated building, there is a unit type building using a box-shaped building unit. In this unit-type building, inner and outer walls, floor and ceiling surface materials, equipment, etc. are pre-assembled in a factory in a rectangular parallelepiped body where the upper and lower ends of four pillars arranged at the four corners are connected by beams. The building units are transported to the construction site by trucks or other vehicles, and the required number of units are stacked and stacked using a crane or the like to form a building.

[0003] By the way, the beams of the building unit are made of a C-shaped steel or an H-shaped steel. Such a shaped steel has a design dimension due to a molding error, a stress or a load at the time of forming the frame. And an error may occur between them. In particular, when the length of one side of the building unit is as long as 5 to 6 m, the warped dimension of the shaped steel may be about 3 mm due to a slight bending of the middle part, and these may cause an adjacent unit in the unit building. Steps between adjacent beams of building units. Further, when the error direction of the upper surface of the beam is opposite between the adjacent beams of the adjacent building units, the step of both beams may be 5 to 6 mm at the middle portion of the entire length of the beam.

As described above, if there is a step between adjacent beams of adjacent building units, the following problem occurs. For example, since a floor material (base plate) is usually directly attached to a beam with a nail or the like, a step occurs on the floor surface between building units. In addition, when arranging a joint surface material that covers a gap between building units (between floor surface materials), the joint surface material is attached in an inclined state.

[0005] As a result, when the floor material of the unit building is finished with a carpet, when walking on the floor, a step between the building units gives an uncomfortable feeling. When a hard finishing material such as a flooring material is attached, there is a problem that the finishing material does not fit well. Further, when furniture or the like is placed between the building units, a gap may be formed between the lower surface of the furniture and the floor surface, and the furniture may become unstable.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and is directed to a beam height adjusting jig for eliminating a step between adjacent beams between building units and a beam between adjacent building units. A height position adjusting method is provided.

It has become.

Also, when adjusting the beam height position, the beam receiving piece 22 and the tip 30b of the screw shaft 30 which will be described later slide with respect to the beams 41 and 51 which are in contact with each other so that the position does not shift. It is preferable to set the thickness t of the piece 21 to a size close to the gap size Q between the adjacent beams 41 and 51. By doing so, even if the position of the jig 10 is slightly shifted between the beams 41 and 51, the intermediate piece 21 does not contact any one of the beams 41 and 51 and does not further shift.

In this embodiment, the intermediate piece 21 itself has a thickness t.
Is formed of a 6 mm steel plate, two bar-shaped struts 24 are formed from appropriate positions of the intermediate piece 21 in the direction in which the adjustment pieces 23 to be described later project, and the jig 10 is displaced by the struts 24. It is designed to suppress. Note that the strut portion 24 is not limited to the rod-shaped member described above, and may have an appropriate shape such as a plate-shaped member. Further, the number of the strut portions 24 to be formed is not limited to two, and one or a plurality of strut portions 24 may be appropriately used.

As will be described later, the beam height adjusting jig 10 is inserted between the adjacent beams 41 and 51 from above or below to position the beam receiving piece 22 and the adjusting piece 23 on the beam surface. Therefore, the values of the width of at least one of the beam receiving piece 22 or the adjusting piece 23, the width W and the thickness t of the intermediate piece 21, the length S of the strut 24, and the like are different between the adjacent beams 41 and 51. The beam height adjustment jig 10 is inserted with respect to the gap dimension Q and is set in consideration of being rotatable.

In this embodiment, the gap dimension Q between the adjacent beams 41 and 51 is 43 mm.
The width W of the intermediate piece 21 is set to 30 mm, the thickness t is set to 6 mm, and the length S of the strut 24 is set to 30 mm.

The beam receiving piece 22 is a portion projecting from one end of the intermediate piece 21 in a direction substantially perpendicular to the vertical direction. The beam receiving piece 22 is provided on the lower surface 41b of the beam 41 of one of the building units 40 when the beam height position is adjusted.
The second upper surface 22a is in contact with the beam 41 and is hooked from below. In this embodiment, the beam receiving piece 22 is formed such that its protruding length L1 is 30 mm.

The adjusting piece 23 is provided from the other end of the intermediate piece 21.
It is a portion projecting in a direction substantially perpendicular to the vertical direction and in a direction opposite to the beam receiving piece 22. The adjusting piece 23 is provided with a screw hole 25, and the screw shaft 30 is screwed into the screw hole 25. The screw hole portion 25 of this embodiment includes a hole 26 penetrating from the upper surface 23a to the lower surface 23b of the adjustment piece 23, and a nut 27 fixed to the hole 26 portion of the adjustment piece lower surface 23b by welding or the like. However, a female screw with which the screw shaft 30 is screwed into the hole 26 may be directly cut. Also, the adjusting piece 2 of this embodiment
3 is formed such that its protruding length L2 is 80 mm.

The main body 20 of this embodiment has a thickness of 6 m.
m, bending a substantially rectangular steel plate in a plan view with a width of 30 mm,
It is formed in the shape described above. Further, between the intermediate piece 21 and the adjustment piece 23 of this embodiment, a reinforcing plate 28 for preventing the intermediate piece 21 and the adjustment piece 23 from being deformed by the force applied at the time of adjusting the beam height position is welded or the like. It is fixed.

The screw shaft 30 is screwed into the screw hole 25 of the adjusting piece 23 and rotated, so that the tip 30 b
Abuts against and presses against the upper surface 51a of the beam 51 of the other building unit 50, and the adjacent building unit 4
The beams 41 and 51 adjacent to each other 0 and 50 are attracted to each other to align their height positions. At the rear end of the screw shaft 30, a shaft head 31 such as a handle for rotating the screw shaft 30 or a tool holder is formed.

As the screw shaft 30, an appropriate one may be used, but if a screw having the same diameter as a bolt used for connecting the building units 40 and 50 is used, a common tool for rotating is used. This is preferable because it is not necessary to prepare it separately. In this embodiment, a bolt (12 mm hexagonal head bolt, shaft length 60 mm) for connecting building units is used.

As long as the beam height position adjusting jig has the same effect, the main body does not need to be a plate-like member formed by bending a steel plate as described above, but may have an appropriate shape. Is good. For example, a beam height position adjusting jig 110 as shown in FIG. 5 as another embodiment may be used. This beam height position adjusting jig 110 has a pipe-shaped intermediate piece 121 having a diameter slightly smaller than the gap dimension Q between the beams, instead of the plate-shaped intermediate piece 21 and the strut portion 24, and the one end side of the pipe-shaped intermediate piece 121. The projecting beam receiving piece 122 is fixed similarly to the embodiment,
It comprises a main body 120 to which an adjustment piece 123 protruding is fixed on the other end side in the same manner as in the above embodiment, and a screw shaft 130 screwed into a screw hole 125 of the adjustment piece 123.

The shape, size and the like of the beam height adjusting jig are adjusted according to the size and shape of the beam whose height is to be adjusted.
It may be set appropriately.

Next, a method of adjusting the beam height position between adjacent building units 40 and 50 using the beam height position adjusting jig 10 will be described.

First, as shown in FIG. 6, between the adjacent beams 41, 51 of the adjacent building units 40, 50, the beam receiving piece 22, the adjusting piece 23 for the beams 41, 51 and the intermediate piece 21, and the projecting portion. The beam height adjusting jig 10 is inserted so that the projecting directions of the beams 24 are substantially parallel. At this time, the jig 10 is inserted from above or below the beams 41 and 51. By inserting the jig 10 in this manner, the beam receiving piece 22 or the adjusting piece 23 does not interfere with the insertion.

Next, with the jig 10 being inserted between the beams 41 and 51 as described above, the jig 10

The side on which the beam receiving piece 22 of the intermediate piece 21 protrudes is brought into contact with the side of the beam that is lowered as a step, in this case, the side face 41 c of the beam 41 of one building unit 40, and the upper surface of the beam receiving piece 22. 22a is brought into contact with the lower surface 41b of one of the beams 41 and is hooked on the beam 41 from below. Further, due to the rotation, the adjustment piece 23 protruding in the opposite direction to the beam receiving piece 22 is positioned above the beam 51 of the other building unit 50.

Then, the screw shaft 30 screwed into the screw hole 25 of the adjusting piece 23 is rotated, and the tip 30b is brought into contact with and pressed against the upper surface 51a of the beam 51 of the other building unit 50. Then, while the beam receiving piece 22 pushes up the beam 41 of one building unit 40 upward, the tip 30b of the screw shaft 30 pushes down the beam 51 of the other building unit 50 downward. In this manner, the adjacent beams 41, 51
And adjust them so that their height positions are the same.

Thereafter, the beams 41, 5 at the same height position
Attach bracket 60 etc. to bolt 1 or welding, etc.,
After connecting and fixing the beams 41 and 51, the screw shaft 30 of the beam height adjusting jig 10 is rotated in the opposite direction to loosen the beam 4, 51.
The beam height adjustment jig 10 is removed from the beams 1 and 51, and the beam height adjustment jig 10 is rotated about 90 degrees about the vertical direction, and pulled out above or below the beams 41 and 51. In this embodiment, bolts are used to mount the bracket 60 for fixing the beams 41 and 51. Reference numerals 61 and 62 denote holes on the bracket 60 side for inserting bolts and the like when mounting the bracket, and 43 denotes a bracket. These are screw holes on the side of the beam 41 into which bolts and the like are inserted when mounting is performed.

The material for the beam height position adjusting jig may be any material as long as it has sufficient strength and rigidity to withstand the tensile force and bending force when correcting the beam position error. Also, here, the lower beam (floor beam) in the building unit
In the description above, the height position of the upper beam (ceiling beam) in the building unit can be adjusted. Further, the beam height position adjusting jig may be turned upside down as shown to adjust the beam height position.
