Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a beam post for supporting a floor beam such as a puller or joist supporting a floor, and more particularly, to easily and quickly adjust a floor height of a floor beam. The present invention relates to a floor framing construction method capable of efficiently constructing a floor framing using a level adjustable beam post and the beam post,
Particularly suitable for flooring work of reinforced concrete buildings.

[0002]

2. Description of the Related Art As is well known, a floor structure of a building is constructed by erecting a plurality of beam posts on a slab and supporting a floor beam (for example, a giant pull or a joist) on these beam posts. The method of going is adopted.

[0003] In such a floor assembly, a beam post P 'consisting of a cut bolt and a nut is usually used (see Fig. 10). A conventional floor construction method for supporting and fixing, for example, a large-scale drawing using the beam post P 'is as follows.

[0004] First, a plurality of trim bolts are welded and fixed to required portions of a deck plate provided as a formwork of a concrete slab, and then concrete is cast on the deck plate to form a slab. Next, insert a nut and a lower washer into each of the welding fixed bolts,
The lower washers are fixed to the bolts with nuts so that they are aligned at the same level while looking at the level from the slab surface. Holes are accurately drilled at the same intervals as the bolts, and each bolt is inserted into these holes, and the pulling is supported by the lower washer. Then, while turning each nut on the lower side of the large pull to fine-adjust the level again, the upper washer and the nut are inserted from above the bolts inserted into the holes of the large pull to tighten and fix the large pull.

However, in the conventional floor construction method as described above, the level of the large pull must be adjusted by rotating a small nut located below the large pull with a spanner or the like. The work is difficult and troublesome. In particular, when performing floor construction work on two or more floors, increase the distance between the slab surface and the lower surface of the large pulling floor. If the height of the building itself is high or the height of the building is not changed, the ceiling height of the room will be low. It is necessary to keep the floor level as low as possible because it causes inconveniences such as falling down. Usually, the distance between the slab surface and the large undersurface is very small, about 20 to 50 mm. Therefore, in the related art, the level adjustment operation of turning the nut by the spanner operation with the hand of the site worker putting the hand in the narrow gap is very difficult and time-consuming. In addition, such a level adjustment operation has to be performed twice before the bolt is inserted into the large pull (temporary adjustment) and after the bolt is inserted (fine adjustment), and the work efficiency is poor. In addition, since a plurality of small bolts for supporting the large pulling are welded and fixed to the deck plate at required intervals, the welding work also takes time. Furthermore, since the holes into which the bolts thus welded and fixed are to be inserted must be roughly and accurately positioned and drilled, there is a problem that high-precision drilling is required.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems in the conventional floor-building method. It is an object of the present invention to provide a level-adjustable beam post that can be easily and quickly adjusted.

Another object of the present invention is to provide a floor construction method capable of efficiently constructing a floor using the beam post as described above.

[0008]

Means adopted by the present inventor for solving the above technical problem will be described below with reference to the accompanying drawings.

That is, the present invention relates to a bearing member which is arranged on a slab and is inserted into an insertion hole formed in a floor beam such as a large-scale or joist to support the floor beam at a required level. A bolt portion fixed to the upper portion; a female screw cylinder screwed to the bolt portion so as to be vertically adjustable, and a lower portion having a bearing portion for receiving the floor beam;
The feature is that the above problem has been solved by adopting a post means that the level of the floor beam can be adjusted by rotating the female screw cylinder in the forward and reverse directions.

[0010] The present invention also provides a floor beam in which a beam post of an adjustment bolt mechanism is mounted in each insertion hole formed in accordance with an interval between beam posts to be lined up on a slab to be laid. The beam post is fixedly arranged at a predetermined position on the slab, and when there is a deviation in the level of the supported floor beam, the level is adjusted by screw-operating the beam post at a portion where the level deviation is present. A beam means of an adjusting bolt mechanism having a beam bearing portion is fixedly erected at a predetermined interval on a slab to be erected, or on a slab to be erected. Holes are formed in accordance with the intervals between the beam posts to be formed, and the floor beam is supported on the beam support portions of the respective beam posts through the holes. The above problem is solved by adopting a method in which when the level of the supported floor beam has a deviation, a level is adjusted by screw-operating the beam post at a portion having the level deviation to construct a floor assembly. There is a characteristic in that.

By simply rotating the female screw cylinder 2 from the upper part of the insertion hole 51 of the large puller 5 in the normal / reverse direction, the distance between the lower surface of the large puller 5 and the slab S surface is adjusted to adopt the floor of the large puller 5. The high level can be adjusted easily and quickly, and there is no trouble that the field worker manually rotates the adjustment nut in the narrow gap between the lower surface of the large puller 5 and the slab S surface as in the conventional construction method. In addition, such a level adjustment operation only needs to be performed once after the female screw cylinder 2 is inserted.
Before bolt insertion (temporary adjustment) and after bolt insertion (fine adjustment)
It is not necessary to adjust the level twice. Therefore, the work efficiency in floor construction is greatly improved.

Although the embodiments of the present invention are generally as described above, the present invention is by no means limited to the above-described embodiments, and various modifications are possible within the scope of the claims. For example, in the present embodiment,

Further, in the female screw cylinder 2 of the present embodiment, a nut part 22 buried in the lower part of the female screw cylinder 2 is used, but the nut part having the female screw 22a is used.
A female screw 22a may be formed on the inner peripheral surface of the female screw cylinder 2 without embedding the female screw 22.

In the present embodiment, the bolt 1
Although the metal material is used as the material of the nut portion 22 of the female screw cylinder 2, the bolt portion 1 and the nut portion 22 are formed of a synthetic resin material (for example, an engineering plastic such as a nylon material containing glass fiber). Is also possible.

Further, in the floor construction method of the present embodiment, the beam posts P, P,.
After the beam posts P are mounted on the slab S, the beam posts P, P,... Are first placed on the slab S at predetermined intervals. Then, the large pull 5 is passed through each insertion hole 51 of the large pull 5 to each beam post P, and the large pull 5 is attached to the support portion 21 of each beam post P.
It is also possible to adopt a construction method of allowing the above to be supported, and it is needless to say that any of these modified embodiments belongs to the technical scope of the present invention.
