Description

Stirrup anchor slab form removal-free cavity prefabricated part

Technical Field

The utility model relates to a concrete building engineering technical field, in particular to stirrup anchor slab exempts from to tear open mould cavity prefabricated component.

Background

The assembly type building is a basic component forming the building, is prefabricated in a factory and then is transported to a construction site for assembly, and is one of building industrialization technologies vigorously promoted in recent years in China. The form-stripping-free concrete pouring formwork system is a novel concrete pouring formwork system, and the formwork is permanently poured together with concrete after being erected and is not dismounted. Because of low cost and high efficiency, the method is gradually accepted by the industry.

The fabricated concrete building occupies a leading position in the field of fabricated building engineering in China. Especially, the precast concrete hollow components which are popular in recent years are gradually accepted by the market by the characteristics of convenient connection of a steel bar system, simple and convenient prefabrication process, low manufacturing cost and the like.

The existing precast concrete hollow components at home and abroad have the following three structural forms:

1. prefabricating a hollow concrete member: and pouring the stressed main reinforcement of the member into the concrete slab, wherein the concrete slab is used as a cavity secondary pouring template of the hollow member. The problems of the above structure in practical implementation are: 1) Complicated molding equipment is required; 2) The factory components are heavy; 3) The stressed main reinforcement is poured into concrete, and the components are difficult to be connected up and down, left and right; 4) The hollow inner cavity is difficult to be rough, and secondary pouring concrete is easy to be layered; 5) The comprehensive cost is high, and the connection quality is poor.

2. Prefabricating a formwork cavity member: the exterior of the steel bar system is provided with a non-dismantling formwork, and the formwork counter-pull rod passes through the non-dismantling formwork and the steel bar system inside the formwork to carry out counter-pull. The problems of the above structure in practical implementation are: 1) Special equipment is needed for molding; 2) The method can only be used for manufacturing two-side symmetrical prefabricated components such as wall structures, can not be used for manufacturing three-side non-dismantling mold components such as prefabricated beams, and can not be used for manufacturing four-side non-dismantling mold components such as prefabricated columns; 3) The disassembly-free template is large in thickness and occupies space; if the thickness is reduced, the anchoring force of the pull rod is insufficient, and the die is easy to expand; 4) The anti-expansion mould only depends on the counter pull rod, and the pull rod is thin or is inserted into the mould-disassembly-free shallow mould, so that the mould is easy to expand; 5) The molding process is complex and the cost is high.

3. The built-in back arris prefabricated cavity component: the built-in back edge is arranged on the inner side of the component steel bar system, the non-dismantling formwork is arranged on the outer side of the component steel bar system, and the anchoring nails sequentially penetrate through the non-dismantling formwork, the steel bar system and the built-in back edge for anchoring. The problems of the above structure in practical implementation are: 1) The anchoring nail is long, and the forming is difficult; 2) The built-in back ridges easily conflict with a steel bar system; 3) When pouring and vibrating, the vibrating rod is easy to collide with the anchoring nail.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the technical problem that current structure exists, providing an exempt from to tear open mould cavity prefabricated component structure.

In order to achieve the above object, the utility model provides a following technical scheme:

the stirrup anchor plate formwork-removal-free cavity prefabricated part comprises a main member rib, a member stirrup and a formwork-removal-free plate, wherein the main member rib is arranged along the length of the member, and the member stirrup is uniformly arranged outside the main member. Still be equipped with the stirrup anchor slab, the stirrup anchor slab be evenly distributed's strip panel, the stirrup anchor slab replaces partial component stirrup, the stirrup anchor slab encircles outside the component stirrup, forms frame column structure, the stirrup anchor slab sets up the position the same with the component stirrup position that replaces.

And a steel bar protective layer cushion block is arranged between the component stirrup or the stirrup anchor plate and the non-dismantling template.

The stirrup anchor plate is internally provided with a reinforcing rib which is a counter-pulling device, and two end parts of the reinforcing rib are connected with the stirrup anchor plates on two sides.

And an anchoring nail is arranged between the non-dismantling template and the component stirrup or the stirrup anchor plate.

The utility model has the advantages that:

1: the stirrup anchor plate is arranged outside the main reinforcement and is parallel to the traditional stirrups, so that the traditional stirrups can be replaced, and the construction cost is reduced;

2: compared with a back edge structure clinging to the outside of the protective layer, the stirrup anchor plate of the patent is used as an in-die back edge without dismantling and is arranged on the inner side of the reinforcing steel bar protective layer, so that the thickness of the protective layer is not influenced;

3: for exempting from to tear open stupefied system of mould back of body structure that sets up in the stirrup, the anchor nail that this patent stirrup anchor slab needs is shorter, easy operation.
