Description

Technical Field

[0001] The utility model relates to the technical field of concrete precast slabs, and specifically refers to a concrete slab splicing unit. Background Technique

[0002] A concrete slab, that is, a precast slab, is a module or plate used in engineering. Since it is a concrete precast member produced and processed in a precast yard, it is directly transported to the construction site for installation.

[0003] When making a concrete slab, first nail a hollow model with wooden boards. After arranging steel bars in the hollow part of the model, fill the hollow part with cement. After it dries, knock off the wooden boards, and what remains is the concrete slab. Concrete slabs have many uses in construction, such as the cement slabs covering the ditches beside the road; the cement slabs used as heat insulation layers on the roof; and the cement slabs used to make fences are all concrete slabs.

[0004] Existing concrete slabs used to make fences do not have a splicing structure, the connection firmness is poor, it is not convenient for installation, and there is room for improvement. Content of the Utility Model

[0007] (2). Technical Solution

[0008] To solve the above technical problems, the technical solution provided by the utility model is: a concrete slab splicing unit, including sequentially spliced concrete slabs, the upper and lower concrete slabs are connected by a mortise and tenon structure, and the left and right concrete slabs are connected by mortise and tenon blocks;

[0009] Symmetrically matched notches are provided on the side of the concrete slab, the mortise and tenon blocks are arranged in the notches, and the mortise and tenon blocks are tightly connected by bolts.

[0010] As an improvement, a conical convex strip is provided on the top of the concrete slab, and a conical notch for accommodating the conical convex strip is provided at the bottom.

[0011] As an improvement, the notch is conical.

[0012] As an improvement, a reinforcing plate embedded in the concrete slab is provided in the notch, and the bolt penetrates through the reinforcing plate.

[0013] (3). Beneficial Effects

[0014] The advantages of the utility model compared with the prior art are as follows:

[0015] 1. The upper and lower concrete slabs are connected by tenon and mortise joints of conical ridges and conical notches, which have good firmness.

[0016] 2. The left and right concrete slabs are connected by tenon blocks and fixed by bolts. The reinforcement plates embedded in the concrete slabs can make the connection between the concrete slabs more firm. BRIEF DESCRIPTION OF THE DRAWINGS
