Description

Technical Field

[0001] The utility model relates to the technical field of precast concrete panels, in particular to a novel precast concrete panel. Background Art

[0002] Precast concrete panels are prefabricated concrete panels that only need to be hoisted to the installation location for installation. They have the advantages of fast construction speed and no need to wait for the concrete to dry.

[0003] When making precast concrete panels, the steel frame is first placed in a mold, then concrete is poured into the mold and vibrated to make the concrete dense. The top concrete is then smoothed and allowed to dry.

[0004] In the actual operation process, the steel frame often tilts, deflects, etc., which affects the strength of the precast concrete slabs. In addition, the steel frame is mostly a single-layer structure, and the strength of the precast concrete slabs used is not high, which needs to be improved. Utility Model Content

[0005] (1) Technical problems solved

[0006] The technical problem to be solved by the utility model is to overcome the above difficulties and provide a new precast concrete slab in which a steel frame will not tilt or deflect; the steel frame is a multi-layer structure and the precast concrete slab body has high strength.

[0007] (2) Technical solution

[0008] In order to solve the above technical problems, the technical solution provided by the present invention is as follows: a new precast concrete panel, comprising a precast concrete panel body, a steel frame embedded in the precast concrete panel body, and adjustment devices provided at both ends of the steel frame;

[0009] The adjusting device comprises a screw barrel fixedly connected to the steel bar frame, wherein a stud is arranged in the screw barrel.

[0010] As an improvement, the number of the steel bar frames is two and they are symmetrically arranged.

[0011] As an improvement, positive and negative studs extending into the screw barrel are provided between the steel bar frames.

[0012] (3) Beneficial effects

[0013] The advantages of this utility model compared with the prior art are:

[0014] 1. The steel frame is a double-layer structure, and the steel frames are fixedly connected by an adjustment device to make the precast concrete slab body stronger;

[0015] 2. The adjusting device includes a screw barrel fixedly connected to the steel bar frame, a screw rod and a positive and negative screw rod arranged in the screw barrel. The screw rod can support the steel bar frame so that it is in the middle position of the precast concrete slab body and will not tilt or shift; the positive and negative screw rod can adjust the distance between the steel bar frames.
