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

Embodiment Construction
[0020] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0021] Refer to attached Figures 1 to 5 The clear-faced concrete open-faced strip that is not easy to damage open-faced joints during demoulding in the figure is installed on the formwork 1, and is used for forming open-faced joints when clear-faced concrete construction, wherein: comprise two oppositely arranged open-faced forming plates 2, set The end face forming belt 3 and the internal connecting belt 4 between the two open seam forming panels 2 are fixed on the internal connecting belt 4 through the expansion bag 5 that expands the two open seam forming panels 2 by filling gas or liquid expansion The sliding bar 6 and the chute 7 fixed on the template 1 that matches the sliding bar 6; during operation, the expansion bag 5 can be filled...

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 to a clear-faced concrete open seam strip which is not easy to damage the open seam when demoulding. Background technique [0002] Fair-faced concrete is a kind of concrete that directly uses the natural texture of concrete after molding as a finishing effect. After molding, its surface is required to be smooth and flat, with sharp edges and corners, without damage and pollution. Calm appearance charm. Compared with traditional concrete projects, fair-faced concrete has the advantages of shortening the construction period, reducing safety hazards, and reducing 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 benefits. With the objective demand for green buildings and the continuous improvement of people's awareness of environmental protection, the na...
