Description

Technical Field

[0001] This utility model relates to the field of crack-resistant structural technology, and in particular to a crack-resistant structure for reinforced concrete surface layer. Background Technology

[0002] Crack-resistant structures are devices used to support concrete surfaces. When using reinforced concrete surfaces, steel bars are first welded into steel support frames, and then the mixed concrete is poured onto the support frames, ensuring that the concrete exceeds the top of the support frames. This can, to some extent, prevent cracks from forming in the concrete surface.

[0003] In their daily work, the inventors discovered that the crack-resistant structure still has at least the following problems: When using reinforced concrete surface layer, the steel bars are first welded into a steel support frame, and then the mixed concrete is poured onto the support frame, ensuring that the concrete exceeds the top of the support frame. This can prevent cracks in the concrete surface layer to a certain extent. However, in actual use, the steel bars may be squeezed and deformed when the concrete is poured. This results in different degrees of support from the support frame, which in turn affects the crack resistance efficiency to a certain extent. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a crack-resistant structure for reinforced concrete surface layers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a reinforced concrete surface layer crack-resistant structure, including a support frame, in which support devices are uniformly arranged, and a connecting device is provided on one side of the support device. The support device includes support bars, two of which are arranged inside the support frame, and a connecting groove is provided on one side of each of the two support bars. A rectangular bar is slidably connected to the inner wall of the connecting groove.

[0006] The effect achieved by the above components is as follows: when using the support device, the support device is evenly placed on both sides and inside the support frame, and then the rectangular strip is slid into the inside of the connecting groove. In this way, the support frame can be supported by the support strip, which to a certain extent avoids the support frame being squeezed and deformed when pouring concrete.

[0007] Preferably, a first damping rod is fixedly connected between the two support bars, and a first spring is sleeved on the surface of the first damping rod. The two ends of the first spring are fixedly connected to the opposite sides of the two rectangular bars, respectively.

[0008] The effect achieved by the above components is that by pulling the two support bars with the first spring, the two support bars can be brought closer to each other, thereby effectively confining the rectangular bar inside the connecting groove.

[0009] Preferably, each of the support bars has a limiting groove at the end away from the first damping rod, and rectangular blocks are uniformly fixedly connected to the bottom of the inner wall of the limiting groove.

[0010] The effect achieved by the above components is to secure the limiting groove to the surface of the reinforcing bar. Because the surface of the reinforcing bar is uniformly textured, the reinforcing bar can be secured inside the limiting groove by the rectangular block.

[0011] Preferably, the inner wall of the connecting groove is provided with a first fixing groove, and the inner wall of the first fixing groove is provided with a round block. The round block and the rectangular strip are fixedly connected to each other on the side near the round block. A notch is provided on one side of the round block. A threaded rod is rotatably inserted into the bottom of the notch. The threaded rod is threaded through and inserted into the top of the inner wall of the notch. A limiting strip is fixedly connected to the bottom of the inner wall of the notch. The top of the limiting strip is slidably inserted into the top of the inner wall of the notch.

[0012] The effect achieved by the above components is as follows: the round block is slid into the inside of the first fixed groove, and the threaded rod is manually controlled to rotate under the restriction of the limiting strip, thereby lengthening the rectangular strip through the notch, which makes it easier to set the two support strips in the inner wall of the support frame through the rectangular strip.

[0013] Preferably, the connecting device includes a sliding bar, which is disposed on one side of the support bar, and a sliding groove is provided at one end of the other support bar, the inner wall of which is slidably connected to the sliding bar.

[0014] The effect achieved by the above components is that when using the connecting device, the sliding bar is slid into the sliding groove, which allows the support devices to be spliced ​​together, making it easier to disassemble the support devices and thus facilitating their transportation.

[0015] Preferably, a second fixing groove is provided on the side of the sliding groove near the support bar, and a fixing block is slidably connected to the inner wall of the second fixing groove, and the fixing block is fixedly connected to one side of the sliding bar.

[0016] The effect achieved by the above components is to slide the fixing block into the inside of the second fixing groove, which makes it easier to restrict the sliding strip inside the sliding groove, and thus makes it easier to fix the separate support devices together.

[0017] Preferably, a rubber block is fixedly connected to the inner wall of the sliding groove, and the rubber block is located on the side of the sliding strip away from the fixed block.

[0018] The effect achieved by the above components is to slide the fixing block into the second fixing groove, thereby effectively squeezing the rubber block to the side of the sliding strip away from the fixing block, which makes it easier to confine the fixing block inside the second fixing groove.

[0019] Preferably, a positioning groove is provided on one side of the support bar, the inner wall of the positioning groove is slidably connected to the inner wall of the sliding bar, a second damping rod is fixedly connected to one side of the inner wall of the positioning groove, the end of the second damping rod near the positioning groove is fixedly connected to one side of the sliding bar, a second spring is sleeved on the surface of the second damping rod, one end of the second spring is fixedly connected to one side of the inner wall of the positioning groove, and the end of the second spring near the second damping rod is fixedly connected to one side of the sliding bar.

[0020] The effect achieved by the above components is that the sliding bar is pressed away from the first damping rod by the second spring, thereby effectively confining the fixing block inside the second fixing groove.

[0021] In this invention, by setting up a support device, when using the support device, the support device is evenly placed on both sides and inside the support frame, and then the rectangular strip is slid into the inside of the connecting groove. In this way, the support frame can be supported by the support strip, which to a certain extent avoids the support frame being squeezed and deformed when pouring concrete.

[0027] Example 1, as Figure 1-4As shown, a crack-resistant structure for reinforced concrete surface layer is provided. Support devices 2 are uniformly arranged inside the support frame 1, and a connecting device 3 is provided on one side of the support device 2. When using reinforced concrete surface layer, the steel bars are first welded into a steel support frame 1, and then the mixed concrete is poured onto the support frame 1, so that the concrete exceeds the top of the support frame 1. This can prevent cracks from occurring in the concrete surface layer to a certain extent.

[0028] Reference Figure 2 and Figure 3 The support frame 1 has support devices 2 evenly arranged inside, and a connecting device 3 is provided on one side of each support device 2. Each support device 2 includes support bars 201, with two support bars 201 disposed inside the support frame 1. A connecting groove 206 is provided on one side of each support bar 201, and a rectangular bar 208 is slidably connected to the inner wall of the connecting groove 206. When using the support devices 2, they are evenly arranged on both sides and inside the support frame 1, and then the rectangular bars 208 are slid into the connecting grooves 206. This allows the support frame 1 to be supported by the support bars 201. This design helps to prevent the support frame 1 from being squeezed and deformed when concrete is poured. A first damping rod 202 is fixedly connected between the two support bars 201. A first spring 203 is sleeved on the surface of the first damping rod 202. The two ends of the first spring 203 are fixedly connected to the opposite sides of the two rectangular bars 208, respectively. By pulling the two support bars 201 with the first spring 203, the two support bars 201 can be brought closer together, thus effectively confining the rectangular bars 208 inside the connecting groove 206, and keeping the support bars 201 away from the first damping rod. Each end of the rod 202 has a limiting groove 204. Rectangular blocks 205 are evenly fixedly connected to the bottom of the inner wall of the limiting groove 204, securing the limiting groove 204 to the surface of the reinforcing bar. Because the surface of the reinforcing bar has evenly distributed textures, the rectangular blocks 205 can hold the reinforcing bar inside the limiting groove 204. The inner wall of the connecting groove 206 has a first fixing groove 207. A circular block 209 is provided on the inner wall of the first fixing groove 207. The circular block 209 and the rectangular bar 208 are fixedly connected to each other on the side closest to the circular block 209. A notch 210 is provided on one side of the circular block 209. A threaded rod 211 is rotatably inserted into the bottom of the notch 210. The threaded rod 211 is threaded through and inserted into the top of the inner wall of the notch 210. A limiting strip 212 is fixedly connected to the bottom of the inner wall of the notch 210. The top of the limiting strip 212 is slidably inserted through and inserted into the top of the inner wall of the notch 210. The round block 209 is slid into the inside of the first fixed groove 207. Under the restriction of the limiting strip 212, the threaded rod 211 is manually controlled to rotate, thereby lengthening the rectangular strip 208 in the notch 210. This makes it easier to set the two support strips 201 in the inner wall of the support frame 1 through the rectangular strip 208.

[0029] Reference Figure 4The connecting device 3 includes a sliding strip 304, which is disposed on one side of the support strip 201. A sliding groove 301 is formed at one end of the other support strip 201. The inner wall of the sliding groove 301 is slidably connected to the sliding strip 304. When using the connecting device 3, the sliding strip 304 is slid into the sliding groove 301, allowing the support devices 2 to be joined together. This facilitates disassembly and transportation of the support devices 2. A second fixing groove 302 is formed on the side of the sliding groove 301 near the support strip 201. A fixing block 307 is slidably connected to the inner wall of the second fixing groove 302. The fixing block 307 is fixedly connected to one side of the sliding strip 304. Sliding the fixing block 307 into the second fixing groove 302 confines the sliding strip 304 within the sliding groove 301, thus securing the separate support devices 2 together. A rubber block 308 is fixedly connected to the inner wall of the sliding groove 301, positioned on the sliding strip 304 away from the fixing block 304. On one side of 7, the fixing block 307 is slid into the interior of the second fixing groove 302, thereby effectively pressing the rubber block 308 onto the side of the sliding strip 304 away from the fixing block 307. This facilitates the confinement of the fixing block 307 within the second fixing groove 302. A positioning groove 303 is provided on one side of the support strip 201. The inner wall of the positioning groove 303 is slidably connected to the inner wall of the sliding strip 304. A second damping rod 305 is fixedly connected to one side of the inner wall of the positioning groove 303. One end of the second damping rod 305 near the positioning groove 303 is fixedly connected to one side of the sliding strip 304. A second spring 306 is sleeved on the surface of the second damping rod 305. One end of the second spring 306 is fixedly connected to one side of the inner wall of the positioning groove 303. The end of the second spring 306 near the second damping rod 305 is fixedly connected to one side of the sliding strip 304. By pressing the sliding strip 304 away from the first damping rod 202 through the second spring 306, the fixing block 307 is effectively confined within the second fixing groove 302.

[0030] Working principle: When using reinforced concrete surface layer, firstly, the reinforcing bars are welded into a reinforcing support frame 1. Then, the mixed concrete is poured onto the support frame 1, ensuring that the concrete exceeds the top of the support frame 1. This can, to some extent, prevent cracks in the concrete surface layer. When using support device 2, it is evenly placed on both sides and inside the support frame 1. The limiting groove 204 is engaged with the surface of the reinforcing bar. Because the surface of the reinforcing bar has evenly distributed textures, the reinforcing bar can be engaged inside the limiting groove 204 by the rectangular block 205. The round block 209 is slid into the first fixing groove 207. Under the restriction of the limiting strip 212, the threaded rod 211 is manually controlled to rotate, thereby lengthening the rectangular strip 208 through the notch 210. This facilitates the placement of the two support strips 201 on the inner wall of the support frame 1 through the rectangular strip 208. In this way, the support frame 1 can be supported by the support bar 201, which to a certain extent avoids the support frame 1 being squeezed and deformed when concrete is poured. When using the connecting device 3, the second spring 306 presses the sliding bar 304 away from the first damping rod 202, thereby effectively restricting the fixing block 307 inside the second fixing groove 302. The fixing block 307 slides into the second fixing groove 302, which makes it easier to restrict the sliding bar 304 inside the sliding groove 301, thereby effectively pressing the rubber block 308 to the side of the sliding bar 304 away from the fixing block 307, which makes it easier to restrict the fixing block 307 inside the second fixing groove 302. In this way, the support device 2 can be spliced ​​together. Reverse operation makes it easy to disassemble the support device 2, which facilitates the transportation of the support device 2.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
