[0002] Post-cast joint construction is a crucial component of the main building construction process. While the post-cast joint is open, a readily fabricated post-cast joint protection device is required to prevent the ingress of debris and sewage. Existing post-cast joint protection methods involve laying a layer of bricks on both sides of the joint, covering it with reinforced concrete precast panels, grouting with waterproof mortar, and then plastering the exterior of the bricks. This construction method is labor-intensive and time-consuming, and the materials are difficult to recycle. Utility Model Content

[0003] The utility model aims to solve the deficiencies of the prior art and provide an easy-to-manufacture and rotatable post-casting belt protection device.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an easy-to-make and revolvable post-cast strip protective device, comprising: a wooden plywood and an angle steel; the wooden plywood is placed in the post-cast strip, and two of the angle steels are respectively installed on both sides of the upper surface of the wooden plywood, the opening direction of the angle steel is facing inward, and the bottom edge of the angle steel covers the gap formed by the wooden plywood and the concrete on both sides of the post-cast strip.

[0005] Furthermore, two rows of first through holes are provided on both sides of the plywood, and a row of second through holes is provided on the bottom edge of the angle steel. The longitudinal spacing between the first through holes is the same as the longitudinal spacing between the second through holes. The angle steel and the plywood are connected by multiple rivets passing through the first through holes and the second through holes.

[0006] Furthermore, the angle steel and the concrete on both sides of the post-cast strip are fixedly connected by masonry mortar.

[0007] Furthermore, the width of the post-cast strip is 800 mm, the width of the plywood is 780 mm, and the thickness is 15 mm.

[0008] Furthermore, the side width of the angle steel is 60 mm and the side thickness is 4 mm.

[0009] The beneficial effects of the utility model are as follows: the utility model provides an easy-to-make and recyclable post-cast strip protection device, the angle steel and the wood plywood are convenient to obtain at the construction site, and the angle steel covers the edge of the wood plywood, so that the gap between the post-cast strip and the wood plywood is completely covered, preventing water and debris from entering, thereby achieving protection for the post-cast strip, and can be recycled, easy to make, simple to install, reliable and durable.

[0015] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0017] like Figures 1 to 3 As shown, an easily fabricated, reusable post-cast strip protection device comprises: a plywood 1 and angle steel 2. The plywood 1 is placed in a post-cast strip 3, with two angle steels 2 mounted on either side of the upper surface of the plywood 1. The openings of the angle steels 2 face inward, and the bottom edges of the angle steels 2 cover the gap formed between the plywood 1 and the concrete 4 on either side of the post-cast strip 3. The angle steels 2 extend to the edges of the plywood 1, completely covering the top of the post-cast strip 3 and preventing water and debris from entering.

[0018] Two rows of first through holes 5 are defined on either side of the plywood 1, and a row of second through holes 6 is defined on the bottom edge of the angle steel 2. The longitudinal spacing between the first through holes 5 is the same as the longitudinal spacing between the second through holes 6. The angle steel 2 and the plywood 1 are connected via multiple rivets 7 passing through the first through holes 5 and the second through holes 6. Compared to securing only the four corners, this provides a more secure fixation, preventing the angle steel 2 from separating from the plywood 1 and causing the post-cast strip 3 to lose its protective function.

[0019] The angle steel 2 and the concrete 4 on both sides of the post-cast strip 3 are fixedly connected by masonry mortar 8.

[0020] The width of the post-cast strip 3 is 800 mm, the width of the wood plywood 1 is 780 mm, the thickness is 15 mm, and the length is determined according to the on-site conditions of the post-cast strip 3.

[0021] The side width of the angle steel 2 is 60 mm and the side thickness is 4 mm.

[0022] The operation method of the utility model is as follows: the wooden plywood 1 is cut from the on-site template, two of the angle steels 2 are taken on-site, the wooden plywood 1 and the angle steel 2 are riveted together by rivets 7, the wooden plywood 1 is placed in the post-cast strip 3, the angle steel 2 is overlapped on the concrete 4 on both sides, and the angle steel 2 is fixedly connected to the concrete 4 by masonry mortar 8, so that the top of the post-cast strip 3 is completely covered to prevent water and debris from entering, thereby achieving the protection function of the post-cast strip 3.

[0023] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or they are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
