Problems solved by technology
[0004] The above-mentioned existing technical solutions have the following defects: in the actual production process, the above-mentioned method can be used for the generation of rough surfaces of precast concrete wall panels, but for precast concrete beams, the joint of two precast concrete beams is generally On the side, during the generation process, the side is generally in direct contact with the mold, so the above-mentioned method of spraying retarder and water gun spray on the concrete surface cannot be used for rough surface generation.

Embodiment Construction
[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0042] refer to figure 1 with figure 2 , is a rough surface mold of a concrete prefabricated part disclosed by the present invention, and the rough surface mold 3 must be used in conjunction with the contour mold 2 fixed on the workbench 1. The contour mold 2 includes several hard and vertically fixed on the working Die plate 21 on stage 1.
[0043] refer to figure 1 with image 3 The rough surface mold 3 includes a base layer 33 and a concave-convex layer 34, the material of the base layer 33 and the concave-convex layer 34 is PPC, PVC, rubber or fiber material, and the base layer 33 and the mold plate 21 are fixed towards the inner side of the contour mold 2, The side of the concave-convex layer 34 away from the base layer 33 is a concave-convex surface 341 in contact with the concrete prefabricated part. Both the rough surface mold 3 and the contour m...

Abstract
The invention relates to a rough surface mold of a precast concrete and rough surface forming process thereof. The rough surface mold comprises a base layer and a concave-convex layer, wherein the base layer and the concave-convex layer are made of PPC, PVC, rubber or fiber materials, the base layer is fixed to the face, facing the interior of an outline mold, of a mold plate, the face, away fromthe base layer, of the concave-convex layer is a concave-convex face making contact with the precast concrete, and a plurality of preformed holes allowing prefabricated steel bars to penetrate throughare formed in the rough surface mold and the outline mold. According to the rough surface mold of the precast concrete and the rough surface forming process thereof, the problem that in the prior art, rough surface generation is difficultly conducted on the side face of a precast concrete member is solved, and the rough surface mold and the rough surface forming process thereof have the effect ofgenerating the high-quality rough surface on the side surface of the precast concrete member.
Description
technical field [0001] The invention relates to the field of concrete prefabricated parts, in particular to a rough surface mold of a concrete prefabricated part and a rough surface generating process thereof. Background technique [0002] Today, the use of prefabricated concrete elements in the construction of buildings is becoming more and more common. Generally speaking, prefabricated concrete components are directly prefabricated in the factory and reach the design strength, and then directly transported to the construction site for hoisting. There are many kinds of concrete prefabricated components. In the process of on-site construction, concrete materials are generally filled on site between two concrete prefabricated components to realize the connection and fixation between the two concrete prefabricated components. Generally speaking, in order to improve the connection strength between two prefabricated concrete components, the surface of the prefabricated concrete...
