Description

Technical Field

[0001] This utility model relates to the field of concrete crack prevention technology, and in particular to a protective device for preventing concrete cracking in floor slabs. Background Technology

[0002] In areas surrounding rivers, concrete floor slabs are more prone to cracking due to special environmental conditions such as soft soil and large water level fluctuations. Therefore, it is necessary to repair the cracks in a timely manner to prevent the building from collapsing.

[0003] Existing crack repair technologies include surface treatment, pressure grouting, and filling and sealing technologies. However, multiple anti-crack and seepage-proof agents cannot be added continuously during the crack filling and sealing process. It is necessary to change the corresponding containers to repair the cracks, which reduces the efficiency of crack repair.

[0004] Therefore, a protective device for preventing cracking in concrete floor slabs is proposed. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a highly practical and simple-to-operate protective device for preventing cracking in concrete slabs. It solves the problem mentioned in the background art that existing crack repair technologies, including surface treatment technology, pressure grouting technology, and filling and sealing technology, cannot continuously add multiple anti-crack and seepage-proof agents during the crack filling and sealing process. Instead, the corresponding containers need to be changed to repair the cracks, thereby reducing the efficiency of crack repair.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective device for preventing cracking in concrete floor slabs, comprising an injection mechanism and a storage tank installed on one side of the injection mechanism. One end of the injection mechanism is provided with a fixing mechanism, and one end of the fixing mechanism is engaged with the top end of a second connecting pipe. The injection mechanism includes a container, inside which a piston is slidably connected, and one end of the piston is fixedly connected with a push rod. A first connecting pipe is fixedly connected to the side of the container away from the push rod, and the top end of the first connecting pipe is threadedly connected to the storage tank. A limiting groove is formed inside the first connecting pipe, and one end of the limiting groove is fixedly connected to a first spring.

[0007] As a further embodiment of this utility model, a rubber ball is fixedly connected to one end of the first spring, and the end of the rubber ball away from the first spring is fitted and connected to the limiting groove. The rubber ball is used to open and close the limiting groove.

[0008] As a further embodiment of this invention, the container is fixedly connected to the second connecting pipe on the side near the first connecting pipe, and the container is used to store the repair agent.

[0009] As a further embodiment of this utility model, the fixing mechanism includes a floor slab body, and a crack is provided on one side of the interior of the floor slab body. Several fixing seats are fixedly connected inside the crack, and the fixing seats facilitate the fixing of the injection mechanism.

[0010] As a further embodiment of this utility model, the number of fixing seats is five, and the fixing seats are evenly distributed inside the crack. One end of each fixing seat is fitted and connected to the second connecting pipe, which facilitates the injection of repair agent into the fixing seat.

[0011] As a further embodiment of this utility model, a fixing ring is fixedly connected to the outer side of the second connecting tube near the fixing seat, and a second spring is sleeved on the side of the second connecting tube near the fixing ring. One end of the second spring is fixedly connected to the fixing ring, and the second spring facilitates the movement of the fixing ring.

[0012] As a further embodiment of this utility model, a sliding cover is slidably connected to the outer side of the second spring. The inner wall of the sliding cover is slidably connected to the second connecting tube. The second connecting tube has a plurality of grooves on the side near the sliding cover. There are eight grooves, and the grooves are evenly distributed at one end of the second connecting tube. A steel ball is provided inside the groove. One side of the steel ball is fitted and connected to the sliding cover, and the other side of the steel ball is fitted and connected to the fixing seat. The steel ball and the fixing seat fix the injection mechanism.

[0013] This utility model provides a protective device for preventing cracking in concrete floor slabs, which has the following beneficial effects:

[0014] 1. This protective device for preventing concrete cracking in floor slabs uses an injection mechanism to continuously inject crack-resistant and waterproofing agent into cracks, filling and repairing them. When the piston moves outward inside the container, it draws the crack-resistant and waterproofing agent from the storage tank into the container. Simultaneously, the rubber ball in the second connecting pipe moves towards the container, preventing the crack-resistant and waterproofing agent from flowing back into the container. When the piston moves inward inside the container, the rubber ball in the first connecting pipe moves and blocks the limiting groove, preventing the crack-resistant and waterproofing agent from flowing back into the storage tank. At the same time, the rubber ball in the second connecting pipe moves, connecting its internal limiting groove, thus completing the injection of the crack-resistant and waterproofing agent and filling the cracks.

[0015] 2. This protective device for preventing cracking in concrete floor slabs can quickly remove the container from the fixed seat by setting a fixing mechanism. By moving the sliding cover and compressing the second spring, the limiting position of the sliding cover on the steel ball can be released, allowing the container to be removed from the fixed seat. When the second spring is not subjected to external force, the spring's own restoring force can drive the sliding cover to return to its original position. At the same time, by utilizing the cooperation between the sliding cover, the steel ball, and the fixed seat, the container can be installed at the end of the fixed seat. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a protective device for preventing cracking of concrete floor slabs, including an injection mechanism 1 and a storage tank 105 installed on one side of the injection mechanism 1. One end of the injection mechanism 1 is provided with a fixing mechanism 2, and one end of the fixing mechanism 2 is engaged with the top end of the second connecting pipe 109. By setting the fixing mechanism 2, the container 101 can be quickly removed from the fixing seat 203. By moving the sliding cover 206 to drive the second spring 205 to compress, the limiting of the sliding cover 206 on the steel ball 208 can be released, and the container 101 can be removed from the fixing seat 203. When the second spring 205 is not subjected to external force, the spring restoring force of the second spring 205 drives the sliding cover 206 to return to its original position. At the same time, by utilizing the cooperation between the sliding cover 206, the steel ball 208 and the fixing seat 203, the container 101 can be installed at the end of the fixing seat 203.

[0026] The injection mechanism 1 includes a container 101, with a piston 102 slidably connected inside the container 101. A push rod 103 is fixedly connected to one end of the piston 102. A first connecting pipe 104 is fixedly connected to the side of the container 101 away from the push rod 103, and a storage tank 105 is threaded to the top end of the first connecting pipe 104. A limiting groove 106 is formed inside the first connecting pipe 104, and a first spring 107 is fixedly connected to one end inside the limiting groove 106. By setting the injection mechanism 1, crack-resistant and seepage-proof agent can be continuously injected into the crack 202 to fill and repair the crack 202. When the piston 102 moves outward inside the container 101, the pressure inside the container 101 drives the rubber ball 108 inside the first connecting pipe 104 to compress the first spring 107, thereby opening the limiting groove 106 inside the first connecting pipe 104. The piston 102 can draw the anti-crack and anti-seepage agent in the storage tank 105 into the container 101. At the same time, the pressure in the container 101 drives the rubber ball 108 in the second connecting pipe 109 to move towards the container 101 and stretch the first spring 107, causing the limiting groove 106 in the second connecting pipe 109 to disconnect, preventing the anti-crack and anti-seepage agent in the crack 202 from flowing back into the container 101. When the piston 102 moves inward in the container 101, the pressure in the container 101 drives the rubber ball 108 in the first connecting pipe 104 to move and block the limiting groove 106, preventing the anti-crack and anti-seepage agent from flowing back into the storage tank 105. At the same time, the pressure drives the rubber ball 108 in the second connecting pipe 109 to move, making its internal limiting groove 106 connected, thus completing the injection of the anti-crack and anti-seepage agent and filling the crack 202.

[0027] A rubber ball 108 is fixedly connected to one end of the first spring 107, and the end of the rubber ball 108 away from the first spring 107 is fitted and connected to the limiting groove 106.

[0028] With the first spring 107 and the rubber ball 108, when the piston 102 moves outward in the container 101, the pressure in the container 101 drives the rubber ball 108 in the first connecting pipe 104 to compress the first spring 107, so that the limiting groove 106 in the first connecting pipe 104 is connected, and the anti-crack and anti-seepage agent in the storage tank 105 can be sucked into the container 101.

[0029] The side of container 101 closest to the first connecting pipe 104 is fixedly connected to the second connecting pipe 109.

[0030] When the piston 102 moves inward within the container 101 via the second connecting pipe 109, the pressure within the container 101 causes the rubber ball 108 within the first connecting pipe 104 to move and block the limiting groove 106, preventing the anti-crack and seepage-proof agent from flowing back into the storage tank 105. Simultaneously, the pressure causes the rubber ball 108 within the second connecting pipe 109 to move, connecting its internal limiting groove 106, thus completing the injection of the anti-crack and seepage-proof agent and filling the crack 202.

[0031] The fixing mechanism 2 includes a floor slab body 201. A crack 202 is provided on one side of the floor slab body 201. Several fixing seats 203 are fixedly connected inside the crack 202.

[0032] The fixing mechanism 2 serves to facilitate the quick assembly and disassembly of container 101.

[0033] There are five fixing seats 203, and the fixing seats 203 are evenly distributed inside the crack 202. One end of the fixing seat 203 is attached to the second connecting pipe 109.

[0034] The fixing seat 203 serves to connect the second connecting pipe 109 and inject anti-crack and seepage-proof agent into the crack 202.

[0035] A fixing ring 204 is fixedly connected to the outer side of the second connecting pipe 109 near the fixing seat 203. A second spring 205 is sleeved on the side of the second connecting pipe 109 near the fixing ring 204. One end of the second spring 205 is fixedly connected to the fixing ring 204.

[0036] The second spring 205 is designed to drive the fixed ring 204 to extend and slide.

[0037] The outer side of the second spring 205 is slidably connected to a sliding cover 206. The inner wall of the sliding cover 206 is slidably connected to the second connecting tube 109. The second connecting tube 109 has a number of grooves 207 on the side near the sliding cover 206. There are eight grooves 207, and the grooves 207 are evenly distributed at one end of the second connecting tube 109. A steel ball 208 is provided inside the groove 207. One side of the steel ball 208 is in contact with the sliding cover 206, and the other side of the steel ball 208 is in contact with the fixing seat 203.

[0038] With the steel ball 208 and the sliding cover 206 in place, the sliding cover 206 can be moved to compress the second spring 205, thereby releasing the limiting effect of the sliding cover 206 on the steel ball 208 and allowing the container 101 to be removed from the fixed base 203. When the second spring 205 is not subjected to external force, the spring restoring force of the second spring 205 can be used to reset the sliding cover 206. At the same time, by utilizing the cooperation between the sliding cover 206, the steel ball 208 and the fixed base 203, the container 101 can be installed at the end of the fixed base 203.

[0039] In this invention, the working steps of the device are as follows:

[0040] First step: By moving the sliding cover 206 to compress the second spring 205, the limiting position of the sliding cover 206 on the steel ball 208 can be released, and the container 101 can be removed from the fixed seat 203. When the second spring 205 is not subjected to external force, the spring restoring force of the second spring 205 drives the sliding cover 206 to return to its original position. At the same time, by utilizing the cooperation between the sliding cover 206, the steel ball 208 and the fixed seat 203, the container 101 can be installed at the end of the fixed seat 203. The container 101 is easy to install and remove.

[0041] Second step: When piston 102 moves outward inside container 101, the pressure inside container 101 drives rubber ball 108 in first connecting pipe 104 to compress first spring 107, causing limiting groove 106 in first connecting pipe 104 to connect, which can draw crack-resistant and seepage-proof agent in storage tank 105 into container 101. At the same time, the pressure inside container 101 drives rubber ball 108 in second connecting pipe 109 to move towards container 101 and stretches first spring 107, causing limiting groove 106 in second connecting pipe 109 to disconnect, preventing crack-resistant and seepage-proof agent in crack 202 from flowing back into container 101.

[0042] The third step: When the piston 102 moves inward in the container 101, the pressure inside the container 101 drives the rubber ball 108 in the first connecting pipe 104 to move and block the limiting groove 106, preventing the crack-resistant and seepage-proof agent from flowing back into the storage tank 105. At the same time, the pressure drives the rubber ball 108 in the second connecting pipe 109 to move, so that its internal limiting groove 106 is connected, thus completing the injection of the crack-resistant and seepage-proof agent and filling the crack 202.
