Abstract

The utility model relates to a PCM concrete hollow floor filling thin wall box internal mold, which solves the problem that: the PCM concrete hollow floor filling thin wall box internal mold with high strength and low cost is provided. The PCM concrete hollow floor filling thin wall box internal mold is characterized in that one side wall of a thin wall rectangle box body is internally provided with more than one reinforcing steel bar penetrating through the side wall, two ends of the reinforcing steel bar extend out of the side wall, and the two extensional ends are connected with a retainer ring. Because the side wall of the box body is internally and additionally provided with the reinforcing steel bar, the integrated intensity and the quality of the tin wall box are improved, and the wastage rate is reduced. Because the extensional ends of the reinforcing steel bar in the box are provided with the retainer ring to be convenient for installation, a mass of reinforcing steel bars can be saved.

Description

The filling thin-walled box internal mold of PCM concrete hollow building roof

Technical field

The utility model relates to the filling thin-walled box internal mold of PCM concrete hollow building roof.

Background technology

Available coagulation soil hollow thin-wall box intensity is low, and cracky is easily stepped on brokenly in construction especially, on the other hand, in work progress, needs to adopt anti-floating reinforcing bar and resist displacement reinforcing bar to fix the usage charges height.

Summary of the invention

The purpose of this utility model is: a kind of intensity height, the filling thin-walled box internal mold of PCM concrete hollow building roof that usage charges are low are provided.

Concrete structural concept is as follows:

The filling thin-walled box internal mold of PCM concrete hollow building roof, comprise the thin-walled rectangular box; the thin-walled rectangular box adds chopped strand, alkali proof fiber grid cloth or the prefabricated combination of gauze wire cloth by concrete and makes; characteristics are: be provided with an above reinforcing bar in described thin-walled rectangular box one sidewall; the reinforcing bar one or both ends extend outside the sidewall, and are connecting retainer ring on the overhanging end.

Be provided with the reinforcing bar that runs through sidewall more than in described thin-walled rectangular box one sidewall, the reinforcing bar two ends extend outside the sidewall, and are connecting retainer ring on two overhanging ends.

Described thin-walled rectangular box is respectively equipped with a reinforcing bar in the two side, and reinforcing bar one end extends outside the sidewall, and is connecting retainer ring on the overhanging end.

Useful technique effect of the present utility model is, owing to set up reinforcing bar in the box side wall, improved bulk strength, the quality of thin-walled box, reduced breakage rate; Be convenient to install because of box body reinforcing bar overhanging end is provided with retainer ring, can save a large amount of reinforcing bars.

Fig. 1 has the bar construction schematic diagram for the utility model end face,

Fig. 2 is the vertical view of Fig. 1,

Fig. 3 has two bar construction schematic diagrames for ipsilateral,

Fig. 4 has the reinforcing bar of perforation schematic diagram for the two side,

Fig. 5 does not connect the reinforcing bar schematic diagram for the two side has,

Fig. 6 is Fig. 4 vertical view.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

By Fig. 1, Fig. 2, Fig. 3 as seen, the filling thin-walled box internal mold of PCM concrete hollow building roof comprises thin-walled rectangular box 1, and thin-walled rectangular box 1 adds chopped strand or alkali proof fiber grid cloth or the prefabricated combination of gauze wire cloth by concrete and makes.Be provided with one or two reinforcing bar 2 that runs through sidewall in thin-walled rectangular box 1 end face, the reinforcing bar two ends extend outside the sidewall, and are connecting retainer ring 3 on two overhanging ends.

In the use, can the thin-walled rectangular box be fixed on down on the steel wire of wearing template, can play the anti-floating muscle, and can control its position in construction and move horizontally, need not in construction, settle anti-floating reinforcing bar and resist displacement reinforcing bar, save a large amount of reinforcing bars by retainer ring.

By Fig. 4, Fig. 6 as seen, be respectively equipped with the reinforcing bar 2 that runs through sidewall in thin-walled rectangular box 1 two side, reinforcing bar 2 two ends extend outside the sidewall, and are connecting retainer ring 3 on two overhanging ends.Other is same as described above.

As seen from Figure 5, be respectively equipped with the reinforcing bar 2 that does not run through sidewall in thin-walled rectangular box 1 two side, reinforcing bar 2 one ends extend outside the sidewall, and are connecting retainer ring 3 on two overhanging ends.Other is same as described above.
