Integrated prefabricated slab

A technology that integrates prefabricated slabs and concrete slabs. It is applied to floors, building components, and structural elements. It can solve the problems of easy displacement of additional steel bars, difficulty in fixing additional steel bars, and inconformity with automated production, so as to reduce the workload of steel bar binding. , Reduce the cost of floor support, and avoid the effect of cracks

Problems solved by technology

[0003] When making traditional reinforced concrete prefabricated slabs in the component factory, due to the outstretched steel bars, different formworks need to be made according to the reinforcement of the prefabricated slabs before pouring, which increases the cost of prefabrication, and the prefabrication efficiency is low, which does not meet the requirements of automatic production
In actual engineering, due to problems such as design defects or insufficient precision of components, conflicts and collisions of steel bars will occur during the hoisting process, which will bring great difficulties to the construction process
[0004] The existing reinforced concrete prefabricated slab technology uses additional steel bars instead of the overhanging parts of the precast slab steel bars to connect with other components such as beams, walls, and cast-in-place layers. When the additional steel bars are prone to displacement

no. 1 example

[0037] Such as Figure 1~6 As shown, an integrated integrated prefabricated slab disclosed by the present invention has additional ribs and pipelines integrated in the prefabricated slab, and its structure includes a concrete floor 1, a plurality of longitudinal concrete ribs 2, two sets of transverse concrete ribs 3 and steel mesh Sheet 4, the inside of the concrete floor is equipped with steel mesh, and the whole is a structure with no reinforcement around it. A plurality of longitudinal concrete ribs are arranged on the concrete floor in parallel and equally spaced, and two sets of transverse concrete ribs are arranged on the concrete floor. At both ends of the ribs, steel mesh sheets are laid on the surfaces of both ends of the longitudinal concrete ribs, and bound with the main bars extending from the ends of the longitudinal concrete ribs.

[0038] Specifically, the inside of the longitudinal concrete rib is provided with a ladder bar 21, the two ends of the ladder bar a...

[0043] Such as Figure 7-9 As shown, it is another structural form of an integrated integrated prefabricated panel disclosed by the present invention. Compared with the structure of the first embodiment, two sets of transverse concrete ribs are removed, but two adjacent longitudinal ribs Concrete blocks 7 are set between the concrete ribs, which have the same effect as the transverse concrete ribs, not only supporting the steel mesh, but also strengthening the overall rigidity of the prefabricated slab. The other structures are consistent with the first embodiment, so no Too much repetition.

no. 3 example

[0045] Such as Figure 10 As shown, it is the third structural form of an integrated integrated prefabricated slab disclosed by the present invention, which uses the concrete blocks in the second embodiment even at the two ends of the longitudinal concrete ribs to form a structure for the reinforcement mesh and the main reinforcement. To the load-bearing role, it also strengthens the overall rigidity of the prefabricated panel.

[0046] The integrated integrated prefabricated slab disclosed by the present invention not only improves the rigidity of the whole prefabricated slab, but also reduces its cost and ensures the connection stability of the subsequent concrete pouring.

Abstract

The invention discloses an integrated prefabricated slab which comprises a concrete bottom plate, a plurality of longitudinal concrete ribs and a reinforcing mesh, ribs are not exposed on the periphery of the concrete bottom plate, the longitudinal concrete ribs are arranged on the concrete bottom plate in parallel at equal intervals, and main ribs extend from the two ends of each longitudinal concrete rib. The extended main reinforcements are bent upwards to form Z-shaped bent sections, and the reinforcing meshes are laid on the surfaces of the two ends of the longitudinal concrete ribs and bound with the bent sections at the two ends of the main reinforcements. According to the integrated prefabricated slab disclosed by the invention, ribs are not exposed out of the bottom plate, and the connection reliability of the additional ribs is also ensured.

Description

technical field [0001] The invention relates to the field of concrete prefabricated panels, in particular to an integrated integrated prefabricated panel. Background technique [0002] The prefabricated concrete slab structure has the advantages of high construction efficiency, energy saving and environmental protection, and precise quality control. The main forms of existing prefabricated laminated slabs are ribbed concrete laminated slabs, prestressed concrete laminated slabs, reinforced truss concrete laminated slabs, etc. The reinforced concrete prefabricated bottom slabs used in the above types of laminated slabs have steel bars protruding all around after the pouring is completed. , to connect with the surrounding components of the prefabricated panel. [0003] When making traditional reinforced concrete prefabricated slabs in the component factory, due to the outstretched steel bars, different formworks need to be made according to the reinforcement of the precast sl...
