Abstract
Description
Positioning device for construction of composite slabs and aluminum alloy formwork. Technical Field
[0001] This utility model applies to the field of building technology, and in particular relates to a positioning device for the construction of composite slabs and aluminum alloy formwork. Background Technology
[0002] Currently, with the steady advancement of prefabricated building development across the country, the construction process of using aluminum alloy formwork to form composite slabs as floor slabs is frequently encountered at prefabricated building construction sites.
[0003] However, currently, when assembling composite panels and aluminum alloy formwork, bolts are used to tighten the surface of the composite panel through to the interior of the aluminum alloy formwork. During this tightening process, there is no corresponding connecting and limiting mechanism between the composite panel and the aluminum alloy formwork. To prevent them from shifting and affecting the stability of the bolt tightening, the operator needs to manually support and limit the movement of the composite panel from the side, making the overall assembly process cumbersome and affecting construction efficiency. Therefore, we propose a positioning device for the joint construction of composite panels and aluminum alloy formwork. Summary of the Invention
[0004] The main purpose of this utility model is to provide a positioning device for the construction of composite slabs and aluminum alloy formwork, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] The positioning device for the construction of composite slabs and aluminum alloy formwork includes a plate body, a first bearing bottom frame and a second bearing bottom frame. The plate body has vertically opened snap-fit grooves inside the four corners of its side. Hollow frames are fixedly installed at both ends of the top inner side of the first bearing bottom frame and the second bearing bottom frame, and the hollow frames are located below the snap-fit grooves.
[0007] Each of the hollow frames is rotatably mounted with a pressing block on its four outer sides, and a pushing mechanism is provided inside the hollow frame, and the pushing mechanism and the pressing block are connected in a transmission manner.
[0008] A connecting mechanism is provided between the top of the first and second load-bearing base frames.
[0009] As an optional solution to the technical solution of this application, the pushing mechanism includes a transmission rod and a pushing spring. A sliding block is slidably installed at the bottom of the pressing block. The transmission rod is inclinedly hinged to the bottom side of the sliding block via a rotating shaft. An extrusion plate is slidably installed in the middle of the inner side of the hollow frame. The bottom of the transmission rod is hinged to the top of the extrusion plate via a rotating shaft. A pushing spring is movably installed at the bottom of the inner side of the hollow frame. The two ends of the pushing spring are movably attached to the bottom surface of the extrusion plate and the bottom surface of the inner side of the hollow frame, respectively. Movable grooves are opened inside the four outer sides of the hollow frame. A rotating rod is fixedly installed on both outer sides of each pressing block. The top end of the rotating rod is rotatably installed on the inner wall of the movable groove via a bearing.
[0010] By adopting the above technical solution, through the transmission action of the transmission rod, when the operator installs the plate onto the top surface of the first and second load-bearing bottom frames, he only needs to continuously press down on the plate to provide the corresponding vertical pushing force to the extrusion plate. This allows the extrusion plate to descend inside the hollow frame while simultaneously compressing the push spring and causing it to deform. After the plate moves to the bottom of the outer side of the hollow frame, combined with the reverse pushing action of the push spring, the pressing block can rotate in the opposite direction and move to the top surface of the plate. The right-angled edge of the bottom surface of the pressing block can abut against the plate and limit its placement, ensuring the stability of the plate when it is spliced with the first and second load-bearing bottom frames, and facilitating subsequent connection and use.
[0011] As an optional solution to the technical solution of this application, a guide slider is fixedly installed on the top surface of the sliding block, and a guide groove is opened at the middle of the bottom of the pressing block, and the guide slider is slidably installed inside the guide groove.
[0012] By adopting the above technical solution, the guide sliding action of the guide slide groove on the guide slider can ensure the rotation of the pressing block and the vertical pushing and pulling force on the extrusion plate, thereby ensuring the rationality of the transmission of the overall mechanism.
[0013] As an optional solution to the technical solution of this application, the connecting mechanism includes a fixed frame and a movable rod. Fixed frames are fixedly installed at both ends of the inner side of the first bearing base frame. A movable rod is slidably inserted through the interior of each fixed frame. Connecting plates are fixedly installed at both ends of the inner side of the second bearing base frame. The top edge of the movable rod is fixedly connected to the outer wall of the connecting plate. A connecting screw hole is opened at the top of the movable rod, and there are several sets of connecting screw holes. A fastening bolt is threaded through the top side of the fixed frame, and the bottom of the fastening bolt is threaded into the connecting screw hole.
[0014] By adopting the above technical solution, through the tightening action of the bolts and the structural action of the movable rod and the fixed frame, the first and second load-bearing bottom frames can be horizontally pushed and pulled to adjust the distance between the first and second load-bearing bottom frames, so that the overall length of the first and second load-bearing bottom frames can be used to connect plates of different lengths, thereby improving the applicability of the overall mechanism.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. The positioning device for the construction of composite slabs and aluminum alloy formwork in this application comprises hollow frames at the top of both the first and second load-bearing bottom frames, and pressing blocks on all four sides of the hollow frames. The device is hinged to both ends of the transmission rod, the bottom of the pressing blocks, and the top of the extrusion plate via a rotating shaft. This allows the operator to continuously press down on the plate when installing it onto the top surfaces of the first and second load-bearing bottom frames. Once the pressing blocks move into the locking groove, the inner wall of the locking groove abuts against the inclined surface of the pressing blocks, allowing the pressing blocks to move within the movable groove around the rotating rod as the center. As the plate retracts into the hollow frame after rotation, it provides a vertical pushing force to the extrusion plate under the connecting transmission of the transmission rod. This allows the extrusion plate to descend inside the hollow frame while compressing the push spring and causing it to deform. After the plate moves to the bottom of the outer side of the hollow frame, the reverse pushing action of the push spring causes the pressing block to rotate in the opposite direction and move to the top surface of the plate. The right-angled edge of the bottom surface of the pressing block can abut against the plate and limit its placement, ensuring the stability of the plate when it is spliced with the first and second load-bearing bottom frames, facilitating subsequent connection and use.
[0017] 2. The positioning device for the construction of composite slabs and aluminum alloy formwork in this application provides a hollow frame at the top of the first bearing bottom frame, and connects the movable rod inserted into the hollow frame and the second bearing bottom frame with a connecting plate. This allows for horizontal pushing and pulling of the first and second bearing bottom frames, adjusting the distance between them. This ensures that the overall length of the first and second bearing bottom frames can be used to connect slabs of different lengths, thereby improving the applicability of the overall mechanism.

[0022] As shown in Figures 1-3, this utility model provides a technical solution: a positioning device for the construction of composite slabs and aluminum alloy templates. The four corners of the side of the slab 1 are vertically provided with snap-fit grooves 11. Hollow frames 2 are fixedly installed at both ends of the top inner side of the first bearing bottom frame 12 and the second bearing bottom frame 13, and the hollow frames 2 are located below the snap-fit grooves 11.
[0023] In this technical solution (as shown in Figures 1, 2, and 3), fixed frames 3 are fixedly installed at both ends of the inner side of the first bearing base frame 12. A movable rod 31 is slidably inserted through the inside of each fixed frame 3. A connecting plate 32 is fixedly installed at both ends of the inner side of the second bearing base frame 13. The top side of the movable rod 31 is fixedly connected to the outer wall of the connecting plate 32. A connecting screw hole 33 is opened at the top of the movable rod 31, and there are several sets of connecting screw holes 33. A fastening bolt 34 is threaded through the top side of the fixed frame 3, and the bottom of the fastening bolt 34 is threaded into the inside of the connecting screw hole 33.
[0024] In this technical solution (as shown in Figures 1, 2, and 3), movable grooves 21 are provided inside the four outer sides of the hollow frame 2. Rotating rods 22 are fixedly installed on both outer sides of each pressing block 23, and the top of the side of the rotating rod 22 is rotatably installed on the inner wall of the movable groove 21 through a bearing. Each of the four outer sides of the hollow frame 2 is rotatably installed with a pressing block 23. A sliding block 25 is slidably installed at the bottom of the pressing block 23. The bottom side of the sliding block 25 is inclinedly hinged to a transmission rod 26 through a rotating shaft. An extrusion plate 24 is slidably installed in the middle of the inner side of the hollow frame 2, and the bottom of the transmission rod 26 is hinged to the top of the extrusion plate 24 through a rotating shaft. A push spring 27 is movably provided at the bottom of the inner side of the hollow frame 2, and the two ends of the push spring 27 are movably attached to the bottom surface of the extrusion plate 24 and the bottom surface of the inner side of the hollow frame 2, respectively.
[0025] In this technical solution (as shown in Figures 1, 2 and 3), a guide slider 28 is fixedly installed on the top surface of the sliding block 25, and a guide groove 29 is provided at the bottom middle of the pressing block 23. The guide slider 28 is slidably installed inside the guide groove 29. The vertical cross-sections of both the guide slider 28 and the guide groove 29 are inverted T-shaped, and the length of the guide groove 29 is less than the bottom width of the pressing block 23.
[0026] During operation, when it is necessary to assemble the plate 1 with the first bearing base frame 12 and the second bearing base frame 13, the adjusting bolts are tightened to move them out from the top of the hollow frame 2 and the movable rod 31. Then, the second bearing base frame 13 is pushed horizontally to adjust the distance between the first bearing base frame 12 and the second bearing base frame 13 so that its overall length is suitable for the length of the plate 1. Then, the fastening bolts 34 are tightened and passed through the hollow frame 2 to be screwed into the connecting screw hole 33 inside the movable rod 31. The plate 1 is then pressed down so that the snap-fit groove 11 on the side of the plate 1 can be aligned with the top surface of the hollow frame 2. The plate 1 is then pressed down so that the inner wall of the snap-fit groove 11 can fit against the inclined surface of the pressing block 23. During the downward movement of the plate 1, the snap-fit groove 11... The wall can abut against the pressing block 23, allowing the pressing block 23 to rotate around the rotating rod 22 inside the movable groove 21 and retract into the hollow frame 2. At the same time, under the transmission action of the transmission rod 26, it provides a corresponding vertical pushing force to the extrusion plate 24. This allows the extrusion plate 24 to descend inside the hollow frame 2 and compress the push spring 27, causing it to deform. After the plate 1 moves to the bottom of the outer side of the hollow frame 2, combined with the reverse pushing action of the push spring 27, the pressing block 23 can rotate in the opposite direction and move to the top surface of the plate 1. The right-angled edge of the bottom surface of the pressing block 23 can abut against the plate 1 to limit its placement. Then, the overall mechanism is fastened and connected using appropriate bolts.
