Floor support structure of building

Abstract

A structure for supporting a floor of a building is provided to conveniently level the floor slab supported in the concrete frame of the building under the floor, and to efficiently use the beam for a long time by lifting up and down the left and right sides of the supporting plate and turning the lower head of the level adjusting bolt with the spanner. A floor supporting apparatus(Fs) is composed of a couple of level adjusting bolts(18) having a horn head(18b) in which a seating plate is mounted on the lower supporting surface and a male screw part extended from the head; a supporting plate(16) having left and right long extension parts in which the male screw part is inserted; a damping rubber(17) supported in the supporting plate; and a lock nut(22) inserted to the male screw part of the level adjusting bolt to lock the supporting plate. A beam is supported in the supporting plate by the damping rubber, and the position of the left or right extension part of the supporting plate is adjusted by turning the level adjusting bolt.

Description

technical field [0001] The present invention relates to the floor support structure of buildings such as apartments, in particular, the level adjustment operation of the floor surface can be easily performed from under the floor, and the replacement and maintenance can be performed simply and conveniently. The short floor support device is a component of the new building floor support structure. Background technique [0002] In a building with a concrete main body such as an existing apartment, the floor support surface of the concrete main body supports a floor structure consisting of a plurality of keel bracket beams and a floor laid on the floor joists on top of it by a floor support member. (For example, refer to Patent Document 1). [0003] [Patent Document 1] Japanese Patent No. 2855491 [0004] Although the horizontal plane of the floor surface of the above-mentioned floor structure needs to maintain accurate levelness for a long period of time, the levelness may no...

Problems solved by technology

[0006] However, since the floor supporting member is installed under the floor, it is difficult to adjust the level of the floor surface under a narrow floor. Therefore, the floor is usually removed and the level of the floor surface is increased as a result. The problem of adjusting costs

[0007] In addition, the multiple keel bracket beams constituting the main part of the above-mentioned floor structure are made of zinc-iron plates with anti-rust performance and have a long service life, and the floor support members supporting them are equipped with cushioning materials such as bolts, nuts, and rubber, etc. Parts, the service life of the floor support components is not only shorter than the keel bracket beam, but also the existing keel bracket beam and floor support components are inseparable structures, although the keel bracket beam still has sufficient service life, it has to be replaced There is a problem of not only increasing costs but also wasting resources when replacing, renovating buildings, etc.
