Clear water concrete clear seam strip capable of not being easily damaged during demoulding

Abstract

The invention relates to a tool used for construction and especially relates to a clear water concrete clear seam strip capable of not being easily damaged during demoulding. The seam strip comprisestwo clear seam forming plates, an end surface forming band, an internal connection band, an expansion capsule, a slide strip and a chute. The two ends of the end surface forming band are fixedly connected to the end portions of the two clear seam forming plates. The two ends of the internal connection band are fixedly connected to the inner side surfaces of the two clear seam forming plates. The slide strip is fixed in the outer side surface of the internal connection band. The internal connection band, the two clear seam forming plates and the end surface forming band form a cavity. The expansion capsule is in the cavity. The expansion capsule is provided with a capsule nozzle used for filling a gas or a liquid in the expansion capsule. The feed inlet of the capsule nozzle is located in the outer side of a template. In the invention, after being separated from the surface of a clear seam, the clear seam forming plates are moved out of the clear seam, the surface of the clear seam is not easy to damage, and the advantage of a clear seam decoration effect can be kept.

Description

Technical field [0001] The invention relates to a construction tool, in particular, it is a fair-faced concrete open seam strip that is not easy to damage the open seam during demolding. Background technique [0002] Fair-faced concrete is concrete that directly utilizes the natural texture of the concrete formed as a finishing effect. After forming, the surface is required to be smooth and flat, with sharp edges and corners, without damage and pollution. The lines of fair-faced concrete are smooth, and the color is uniform. It is simple and natural. A calm appearance. Compared with traditional concrete projects, fair-faced concrete has the advantages of shortening the construction period, reducing potential safety hazards, and lowering project costs, so it has good economic and social benefits; in addition, fair-faced concrete reduces the use of building decoration materials and construction waste, and has good Environmental protection benefits. With the objective demand for g...

Problems solved by technology

[0003] In fair-faced concrete projects, open joints are usually set up to assist construction and decoration; open joints refer to the grid lines or decorative lines recessed into the concrete surface. Or self-tapping screws to fix the top seam strip and the formwork surface, and then remove the formwork and the top seam strip after the concrete is poured, and the position of the top seam strip becomes the top seam. The edge of the open seam causes the concrete to loosen, fall off, and form defects, so that the fair-faced concrete cannot achieve the effect of smooth surface and smooth lines after molding. After the fair-faced concrete is formed, the open seam needs to be repaired or decorated, which increases construction cost
