Technical Field
[0001] The utility model relates to the technical field of building material production, in particular to a prestressed double T-plate mould. Background Art
[0002] Double T-plate is a prefabricated reinforced concrete load-bearing structure that combines plates and beams. It consists of a wide panel and two narrow and high ribs. The panel is both a transverse load-bearing structure and a compression zone for the longitudinal load-bearing ribs. In single-story, multi-story and high-rise buildings, double T-plates can be used as roof panels, placed horizontally on joists or load-bearing walls, or placed longitudinally on roof beams. They can also be installed vertically on strip foundations as wall panels. Double T-plates have good force transmission levels and mechanical properties, large spans, wide coverage areas, and are economical and practical.
[0003] When double T-plates are made using molds, the following processes are required: prestressed steel bar production, concrete pouring, maintenance, demolding and inspection. Maintenance means that after the concrete is poured, in order to ensure that the concrete obtains good strength and durability during the hardening process, it is usually necessary to artificially lay a film on the mold to cover the concrete inside to prevent the concrete from losing water prematurely, promote its full hardening and strength development, and ensure that the final product meets the performance requirements of the design. Utility Model Content
[0004] The purpose of the utility model is to provide a prestressed double T-plate mold to solve the problem proposed in the above background technology that after pouring concrete, two people cooperate to cover a film on the top of the mold to achieve the maintenance of the concrete below, but manual laying requires the cooperation of multiple people to complete the layout of a large area, and the laying time is long, resulting in slow maintenance efficiency.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a prestressed double T-plate mold, comprising: a mold body; a track groove, which is arranged on both sides of the upper surface of the mold body; a moving part, which is placed in the groove of the track groove, and the moving part comprises: a connecting frame, a support column, a moving wheel and a film roller shaft, the bottom of both ends of the connecting frame are welded with support columns, the bottom end of the support column is rotatably connected with a moving wheel, and the moving wheel is located in the track groove, and the two ends of the film roller shaft are rotatably connected to the bearing in the middle of the connecting frame;
[0006] The driving part is placed on one side of the moving part, and the driving part includes: a first sprocket, a second sprocket, a third sprocket, a chain and a handle. The first sprocket is inserted at one end of the film roller shaft, the second sprocket has two groups respectively inserted on the rotating shaft extending from the moving wheel, one end of the handle is rotatably connected to the horizontal bar between the support columns, the third sprocket is inserted on the outer wall of the handle, and the chain is sequentially connected to the first sprocket, the second sprocket and the third sprocket.
[0007] By adopting the above technical scheme, the third sprocket can be driven to rotate by shaking the handle, and the first sprocket and the second sprocket can be driven to rotate together under the chain transmission, the second sprocket drives the moving wheel to move in the track groove, and the first sprocket drives the film roller to rotate to release the film. When the moving part moves to the opposite side of the track groove, the film can be evenly laid on the top of the mold body. The film can be laid quickly by one person shaking the handle, which shortens the time for laying the film and improves the efficiency of maintaining and laying the film.
[0008] Preferably, an insertion hole is provided on the upper surface of the mold body, and a frame is inserted into the interior of the insertion hole.
[0009] By adopting the above technical solution, the frame can be inserted through the socket to lift up the laid film, forming a shorter shed above the concrete, which can prevent the film from sticking to the concrete and damaging the solidified surface. At the same time, the film is easily torn and damaged when it is folded up after adhesion. Lifting can form a protective space, and the maintenance effect can be improved through the above structure.
[0010] Preferably, the insertion holes are opened on the upper surface of the mold body every one meter, and the length of the frame remaining outside after being inserted is smaller than the width of the film on the film roller.
[0011] By adopting the above technical solution, the shape of the film after covering can be more regular by plugging the frames at a spacing of one meter, avoiding the film with a larger spacing from sinking into the gap and affecting the protective effect. At the same time, the length of the frame after plugging is limited, so that there is a section of excess length after the film is laid, and the edge of the film is pressed with a pressure strip, so that the film is stretched tight on the frame to protect the concrete.
[0012] Preferably, side notches are formed at both ends of the mold body, and the side notches are connected to side mold plates via bolts.
[0013] By adopting the above technical solution, the side formwork is connected by bolts through the side notches on both sides. When demoulding, the lower side formwork can be quickly removed, which is convenient for demoulding the double T-plate after solidification.
[0014] Preferably, the film roller is composed of a black opaque film and a roller, and the black film is wound on the roller in a clockwise direction.
[0015] By adopting the above technical solution, an opaque black film can be used to block sunlight, reduce direct sunlight on the concrete surface, help control temperature changes, and improve the strength and durability of concrete. At the same time, the film is wound on the roller clockwise, and the film can be released when the handle is rotated and moved during laying, and the film can be rolled up when the handle is turned, realizing the function of single-person laying and rolling, thereby improving the convenience and efficiency of maintenance.
[0016] Preferably, the lengths of both ends of the two sides of the mold body exceed the length of the double T-plate mold groove, and the excess length is greater than the length of the connecting frame.
[0017] By adopting the above technical solution and limiting the excess length at both ends of the mold body, the moving part and the driving part can be retracted on the track groove of the excess length, so that the part for pouring concrete is left empty for placing steel bars and pouring concrete, thereby reducing the impact of installing the moving part and the driving part on pouring concrete.
[0018] Preferably, the width of the moving wheel can just be placed in the track groove, and the depth of the track groove is smaller than the radius of the moving wheel.
[0019] By adopting the above technical solution and setting the width and height of the moving wheels and the track groove, it can be ensured that when one side of the moving part is subjected to force transmission, the moving wheels on both sides can move synchronously under the restriction of the track groove, avoiding the problem of asynchronous movement and jamming, thereby improving the smoothness of the movement of the moving part.
[0020] Compared with the prior art, the beneficial effects of the utility model are:
[0021] (1) By shaking the handle, the third sprocket can be driven to rotate together, and the first sprocket and the second sprocket can be driven to rotate together under the chain transmission, the second sprocket drives the moving wheel to move in the track groove, and the first sprocket drives the film roller to rotate and release the film. When the moving part moves to the opposite side of the track groove, the film can be evenly laid on the top of the mold body. The film can be laid quickly by shaking the handle by one person, which shortens the time of laying the film and improves the efficiency of maintaining and laying the film;
[0022] (2) Through the structural design of the driving part, when the film is wound on the roller in a clockwise manner and the handle is rotated counterclockwise, the film roller rotates clockwise to release the film, and the film can be rolled up when the handle is turned. This structure allows one person to lay and roll up the film, avoiding the problem of manual film rolling causing damage, thereby improving the convenience and efficiency of maintenance and reducing unnecessary costs of damage to production materials.

The bottom end of the support column 302 is rotatably connected to the moving wheel 303, and the moving wheel 303 is located in the track groove 2. The moving wheel 303 is directly placed in the groove of the track groove 2 to regulate the moving path of the moving wheel 303. The two ends of the film roller 304 are rotatably connected to the bearing in the middle of the connecting frame 301. The bearing is clamped in the middle of the connecting frame 301, which is convenient for rotating to release and rewind the film after the film roller 304 is plugged in.
[0031] The driving part 4 is placed on one side of the moving part 3. The driving part 4 includes: a first sprocket 401, a second sprocket 402, a third sprocket 403, a chain 404 and a handle 405. Shaking the handle 405 can drive the third sprocket 403 to rotate together. Under the transmission of the chain 404, the first sprocket 401 and the second sprocket 402 are driven to rotate together. The second sprocket 402 drives the moving wheel 303 to move in the track groove 2. The first sprocket 401 drives the film roller 304 to rotate and release the film. The first sprocket 401 is plugged into one end of the film roller 304. The first sprocket 401 is used to drive the film roller 304 to rotate for releasing and winding. The second sprocket 402 has two groups, which are respectively plugged into the moving wheel 303. On the extended rotating shaft, the second sprocket 402 can drive the moving wheel 303 to rotate and move in the track groove 2. One end of the rotary handle 405 is rotatably connected to the horizontal bar between the support columns 302. The third sprocket 403 is inserted into the outer wall of the rotary handle 405. The chain 404 is sequentially connected to the first sprocket 401, the second sprocket 402 and the third sprocket 403. The third sprocket 403 is driven to rotate by the rotary handle 405.

The film can be rolled up when the rotary handle 405 is turned, realizing the function of single-person laying and rolling, improving the convenience and efficiency of maintenance. The length of both ends of the two sides of the mold body 1 exceeds the length of the double T-plate mold groove, and the excess length is greater than the length of the connecting frame 301. The two ends of the mold body 1 The excess length limit at the end can be used to store the moving part 3 and the driving part 4 on the track groove 2 of the excess length, so that the part for pouring concrete is vacant for placing the steel frame and pouring concrete, thereby reducing the impact of installing the moving part 3 and the driving part 4 on pouring concrete. The width of the moving wheel 303 can just be placed in the track groove 2, and the depth of the track groove 2 is smaller than the radius of the moving wheel 303. The width and height of the moving wheel 303 and the track groove 2 are set to ensure that when one side of the moving part 3 is subjected to force transmission, the moving wheels 303 on both sides can move synchronously under the limitation of the track groove 2, thereby avoiding the problem of asynchronous movement and jamming, thereby improving the smoothness of the moving part 3 when moving.
[0034] Working principle: When in use, first, the third sprocket 403 can be driven to rotate together by shaking the handle 405, and the first sprocket 401 and the second sprocket 402 are driven to rotate together under the transmission of the chain 404, and the second sprocket 402 drives the moving wheel 303 to move in the track groove 2, and the first sprocket 401 drives the film roller 304 to rotate and release the film. When the moving part 3 moves to the opposite side of the track groove 2, the film will be laid on the frame 6 as a whole. At this time, it is only necessary to tighten the film synchronously and press it with a pressure strip. When it needs to be rolled up, the film can be rolled up by rotating the handle 405 and can be returned to its original position.
[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
