Description

Technical Field

[0001] The present application relates to the technical field of supporting structures, and in particular to a supporting structure at a post-cast strip of a roof of an underground garage. Background Art

[0002] The post-cast strips of the underground garage roof refer to the process of dividing the roof into several parts for construction in order to control the construction progress and cost, and to adapt to the shrinkage and expansion of concrete during the construction of the underground garage. In the early stage of concrete pouring, there will be gaps between these parts, namely the post-cast strips. The design and construction of the post-cast strips are an important part of the entire underground garage construction. Before pouring the post-cast strips, it is necessary to install support formwork, which can ensure that the concrete maintains the correct shape and size during the pouring process, and also provides support after the concrete is poured to prevent shrinkage cracks.

[0003] In view of the above-mentioned related technologies, the inventor believes that the supporting formwork used for pouring the post-casting strip is reusable. This is to improve construction efficiency, reduce costs, and meet the requirements of green construction. The supporting formwork used for pouring the post-casting strip may bend and deform to a certain extent during the reuse process. This is because the formwork may deform due to stress concentration, material fatigue or other factors when it bears the weight and pressure of concrete. However, the existing support structure cannot flatten the curved formwork. When the formwork is pressed and fixed, it is often fixed at multiple locations of the formwork. After fixing one location of the formwork, the formwork at that location will not be able to move, which will cause the following problems: when installing the formwork, the two sides of the formwork are first positioned and fixed. After the two sides of the formwork are fixed, when the formwork of the middle curved part is fixed, the curved formwork will gradually flatten and extend to both sides when it is fixed and squeezed, but the two sides of the formwork are fixed and cannot move, which causes the formwork to be unable to restore the flattened state, so that when the formwork is pressed and fixed, there will be a gap between the curved formwork and the concrete, and concrete leakage is prone to occur during pouring. Summary of the invention

[0004] The purpose of the present application is to provide a supporting structure for the post-cast strip of the roof of an underground garage, so as to improve the problem that the existing supporting structure cannot flatten the curved formwork.

The pressure plate is provided with an inclined surface, and the highest point of the rising pressure plate will first contact the formwork. As the connecting plate rotates on the support block, the inclined surface gradually approaches the horizontal, so that the pressure plate can gradually contact the formwork from left to right, and the formwork is extended to the right, thereby realizing the flattening of the formwork, making the formwork in close contact with the concrete, preventing gaps between the formwork and the concrete on both sides of the post-casting strip, and preventing leakage during pouring.

DETAILED DESCRIPTION

[0040] The following is combined with Figure 1 - Attachment Fig.10 , further details of this application are given.

[0041] A supporting structure for the post-cast strip of the roof of an underground garage, referring to Figure 1-3 , including a plurality of support columns, a mounting plate 2 fixedly mounted on the plurality of support columns, the support columns including a base 1, a screw rod 101 threadedly connected to the base 1, and a lifting rod 102 rotatably mounted on the screw rod 101, the mounting plate 2 is fixedly mounted on the plurality of lifting rods 102, and a handle 103 is fixedly mounted on the screw rod 101. The screw rod 101 can be rotated by rotating the handle 103, so that the screw rod 101 can be raised or lowered along the axis direction, and then the lifting rod 102 can be driven to rise and fall, so that the lifting rod 102 can drive the mounting plate 2 to rise and fall, so that the height of the mounting plate 2 can be adjusted according to different building heights to meet the support work of post-casting strips of different heights.

[0042] Reference Figure 4-6 and Figure 8, a plurality of support modules are fixedly mounted on the mounting plate 2, a template 6 is movably mounted on the support module, and the support module includes a support seat 3 fixedly mounted on the mounting plate 2, a slide groove 301 provided on the support seat 3, a slider 302 slidably mounted on both sides of the slide groove 301, a slideway 303 provided on the slider 302, a slide bar 304 slidably mounted on the slideway 303, and a connection block 305 fixedly mounted on the slide bar 304. A connector 306 is detachably mounted on the template 6, and the connector 306 is detachably connected to the two connection blocks 305. After the connecting head 306 is fixedly connected to the template, the connecting head 306 is placed between the two connecting blocks 305, and the connecting block 305 is fixedly connected to the connecting head 306 by bolts. At this time, the connecting block 305 can slide up and down along the slide 303, and the slider 302 can move along the slide groove 301, so that the connecting head 306 can drive the template 6 to move a certain distance on the slide 303 and the slide groove 301, but the moving distance is limited. At this time, the template can be preliminarily positioned. Then the formwork 6 can be pressed. When pressing the formwork 6, it should be pressed gradually from one side of the formwork 6 to the other side, so that the bend on the formwork 6 can be gradually extended to one side. At this time, the formwork 6 can move a certain distance on the slide 303 and the slide groove 301, so that when the formwork 6 is pressed to extend to the outside, the formwork 6 is not subject to resistance, ensuring that the formwork 6 can be fully extended, the formwork 6 is flattened, and the formwork 6 is in close contact with the concrete, preventing gaps from appearing between the formwork 6 and the concrete on both sides of the post-casting strip, and preventing leakage during pouring.

[0043] Reference Figure 4-7 and Fig. 9A plurality of limiting components are installed on the mounting plate 2, and the limiting components limit the support module. The limiting components include a limiting rod 4 fixedly installed on the slider 302, a slide 401 fixedly installed on both sides of the support seat 3, a connecting pipe 402 fixedly installed on the slide 401, a valve 403 fixedly installed on the connecting pipe 402, an oil tank 404 fixedly installed on the connecting pipe 402, a slide 405 slidably installed in the oil tank 404, and a spring 406 fixedly installed on the slide 405, the other end of the spring 406 is fixedly connected to the oil tank 404, and the limiting rod 4 is slidably connected to the slide 401. Hydraulic oil is provided in the oil tank 404, and the hydraulic oil is located on the side of the slide 405 away from the spring 406. When the template 6 is flattened, it will drive the slider 302 to slide, and the sliding slider 302 will drive the limiting rod 4 to move, and the movement of the limiting rod 4 will compress or release the space inside the slide 401. When the valve 403 is opened, the hydraulic oil in the oil tank 404 will move to the inside of the connecting pipe 402 and enter the inside of the slide 401 under the action of the spring 406 and the slide 405. At this time, the movement of the limit rod 4 to the inside of the slide 401 will squeeze the hydraulic oil in the slide 401, so that the hydraulic oil will flow back to the oil tank 404. When the limit rod 4 moves away from the slide 401, the hydraulic oil in the oil tank 404 will fill the space inside the slide 401. When the valve is closed, the hydraulic oil in the slide 401 will not be able to flow back to the oil tank 404, and the hydraulic oil in the oil tank 404 will not be able to enter the slide 401, so that the limit rod 4 cannot move inside the slide 401, and the slider 302 cannot move.

[0044] Before the template 6 is fixed and flattened, the valve 403 should always be opened to allow the template 6 to move and be completely flattened. After the template 6 is completely flattened, closing the valve 403 can prevent the template 6 from sliding and limit the template 6.

[0045] The oil tank 404 is connected to the connecting pipe 402, the connecting pipe 402 is connected to the slide 401, and a sealing ring is installed on the limit rod 4. The sealing ring can prevent the problem of oil leakage at the connection between the slide 401 and the limit rod 4.

[0046] Reference Fig.10The mounting plate 2 is provided with a plurality of pressing and flattening mechanisms, which press and flatten the curved part of the template 6. The pressing and flattening mechanisms include an internal threaded rod 5 rotatably mounted on the mounting plate 2, a threaded rod 501 threadedly connected to the internal threaded rod 5, a support block 502 fixedly mounted on the internal threaded rod 5, a connecting plate 503 rotatably mounted on the supporting block 502, and a pressing plate 504 fixedly mounted on the connecting plate 503. The plurality of pressing plates 504 will cover the entire template 6. When flattening the template 6, the plurality of internal threaded rods 5 on the far left are first rotated to drive the plurality of threaded rods 501 on the far left to rise. The rising threaded rod 501 will drive the pressing plate 504 to rise, so that the pressing plate 504 contacts the template 6, and then the template 6 is flattened by the pressing plate 504, and then pushed rightward at a time, so that the template 6 is gradually extended to the right, so that the template 6 is gradually flattened.

[0047] The pressing plate 504 is provided with an inclined surface 505, and a torsion spring is fixedly installed at the rotation connection between the support block 502 and the connecting plate 503. The torsion spring can ensure that the bottom surface of the pressing plate 504 can be at a horizontal angle when the pressing plate 504 is not subjected to external force, so that there is an angle between the inclined surface 505 and the horizontal plane. At this time, the highest point of the rising pressing plate 504 will first contact the template 6. As the connecting plate 503 rotates on the supporting block 502, the inclined surface 505 gradually approaches the horizontal, so that the pressing plate 504 can gradually contact the template 6 from the left to the right, so that the template 6 extends to the right, thereby realizing the flattening of the template 6. The pressing plate 504 can press and fix the template 6.

[0048] The internal threaded rod 5 penetrates the mounting plate 2, and a handle 506 is fixedly mounted on the internal threaded rod 5, and the handle 506 is located at the lower side of the mounting plate 2. The internal threaded rod 5 can be driven to rotate by rotating the handle 506.

[0049] The implementation principle of the embodiment of the present application is:

[0050] After the connecting head 306 is fixedly connected to the template, the connecting head 306 is placed between the two connecting blocks 305, and the connecting blocks 305 are fixedly connected to the connecting head 306 by bolts. The connecting head 306 can drive the template 6 to move a certain distance on the slide 303 and the slide groove 301. At this time, the template can be preliminarily positioned. Then, the template 6 is flattened. First, the multiple internal threaded rods 5 on the leftmost side are rotated to drive the multiple threaded rods 501 on the leftmost side to rise. The rising threaded rods 501 will drive the pressing plate 504 to rise, so that the pressing plate 504 contacts the template 6, and then the template 6 is flattened by the pressing plate 504. The pressing plate 504 is provided with an inclined surface 505. The highest point of the rising pressing plate 504 will first contact the template 6. As the connecting plate 503 rotates on the supporting block 502, the inclined surface 505 gradually approaches the horizontal, so that the pressing plate 504 can gradually contact the template 6 from the left to the right, so that the template 6 extends to the right, thereby realizing the flattening of the template 6. Then, it is pushed to the right in sequence, so that the template 6 gradually extends to the right, and finally the template 6 is completely flattened. When the template 6 is completely flattened, closing the valve 403 can prevent the template 6 from sliding, and the template 6 can be limited.

[0051] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
