Abstract

The utility model provides a cast-in-place reinforced concrete floor negative reinforcement support, which comprises a support rod and a plurality of support feet, wherein the support feet are distributed in a row, and are vertically and fixedly connected on the support rod at intervals. The cast-in-place reinforced concrete floor negative reinforcement support can effectively fix the positions of cast-in-place reinforced concrete floor negative reinforcements, and has the advantages of simple and reasonable structure, excellent control effect, low cost and simple and convenient manual operation, thereby guaranteeing construction quality of cast-in-place reinforced concrete floors.

Description

In-situ reinforced concrete slab is born the muscle support

[technical field]

The utility model relates to the negative muscle support of a kind of in-situ reinforced concrete slab.

[background technology]

In the building engineering, the negative muscle diameter of in-situ reinforced concrete slab is generally smaller, is trampled distortion easily.In the code requirement concrete construction; operating personnel do not allow directly to trample on the negative muscle of floor; but often do not have under the reliable safeguard measure situation in the concrete work progress; operating personnel and plant equipment etc. just directly drop on the negative muscle of floor; cause that the negative muscle distortion of floor is serious, protective layer thickness is excessive; thereby cause flooring cracking, even the floor bearing capacity is reduced and cause floor to cave in, influence structural safety.For guaranteeing the bearing capacity of floor, take in the industry the negative muscle of floor is supported.

At present, the negative muscle method for supporting of floor mainly adopts reinforcing bar split heads and plastics split heads, but this supporting way still has weak point:

1, the reinforcing bar split heads make highly be difficult to control, deviation is bigger, leaks because human factor is local easily during construction to put or mistake is put and caused split heads lazy weight or placement location lack of standardization, the split heads position is mobile etc. easily during concreting, thereby influences support effect;

2, not environmental protection of plastics split heads product, intensity can not satisfy construction requirement fully, and can not well be bonded together with concrete, influences workmanship.

[utility model content]

The technical problems to be solved in the utility model, be to provide a kind of in-situ reinforced concrete slab to bear the muscle support, effectively fixedly in-situ reinforced concrete slab is born the position of muscle, and have simple and reasonable, control effective, cost is lower, the advantage that manually-operated is easy, thus guarantee the construction quality of in-situ reinforced concrete slab.

The utility model is achieved in that a kind of in-situ reinforced concrete slab bears the muscle support, and it is characterized in that: comprise a pole and a plurality of leg, described a plurality of legs are to arrange to be put, and is separated with distance ground vertical fixing mutually and is connected on the described pole.

Further, described pole adopts diameter to process after being drawn into 6mm for the 8mmHPB300 reinforcing bar, and length is 1000mm; It is that the 4mm wire material is made that described leg adopts diameter, and is processed into " eight " font and struts, and the leg top is welded on the pole.

Further, the leg that is in the pole two ends is 75mm apart from the pole termination, and the distance between adjacent two legs is 170mm, and support foot hight is that the thickness of in-situ reinforced concrete slab deducts floor negative tendon protective layer thickness, negative muscle and a shank diameter sum.

Advantage of the present utility model is: the effectively fixing position of the negative muscle of in-situ reinforced concrete slab, and have simple and reasonablely, to control effectively, and cost is lower, the advantage that manually-operated is easy, thus guarantee the construction quality of cast-in-place concrete floor.

[specific embodiment]

See also illustrated in figures 1 and 2ly, in-situ reinforced concrete slab of the present utility model is born muscle support 1, comprises a pole 11 and a plurality of leg 12, and described a plurality of legs 12 are to arrange to be put, and is separated with distance ground vertical fixing mutually and is connected on the described pole 11.

Described pole 11 adopts diameters to process after being drawn into 6mm for the 8mmHPB300 reinforcing bar, and length is 1000mm; It is that the 4mm wire material is made that described leg 12 adopts diameters, and is processed into " eight " font and struts, and leg 12 tops are welded on the pole 11.

Be in the leg 12 at pole 11 two ends and the distance B 1 of pole 11 terminations and be 75mm; distance B 2 between adjacent two legs 12 is 170mm; in conjunction with Fig. 3 and shown in Figure 4, leg 12 height h are that the thickness H of in-situ reinforced concrete slab 2 deducts the thickness c of floor negative tendon protective layer 3, the diameter d of negative muscle 4 ₁And the diameter d of pole 11 ₂Sum.

Specific operation process when as shown in Figure 3 and Figure 4, the negative muscle support of the utility model uses is as follows:

(1) before the negative muscle 4 of colligation floor, arranging the negative muscle support 1 of floor in negative muscle distribution bar 6 places at interval from negative muscle distribution bar 6 places of first row, beam 5 edges and toward direction between the plate span centre, and replacing the negative muscle distribution bar 6 of corresponding position;

(2) the negative muscle 3 of colligation floor, the negative muscle 3 of floor is placed on the negative muscle support 1 and gets final product with the iron wire colligation; All the other operating process are carried out according to conventional method.

In sum, the utility model is the position of the negative muscle of in-situ reinforced concrete slab effectively fixedly, and has simple and reasonablely, controls effectively, and cost is lower, the advantage that manually-operated is easy, thus guarantee the construction quality of cast-in-place concrete floor.

Though more than described the specific embodiment of the present utility model; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; rather than for the restriction to scope of the present utility model; those of ordinary skill in the art are in modification and the variation of the equivalence of doing according to spirit of the present utility model, all should be encompassed in the scope that claim of the present utility model protects.
