Description

Technical Field

[0001] The invention relates to the technical field of water seepage prevention treatment of prefabricated components, and in particular to a water seepage prevention structure for vertical seams of prefabricated components. Background Art

[0002] Prefabricated components refer to building components that are cast, formed and cured in advance in the factory according to the design requirements, and then transported to the construction site and assembled into a complete building through reliable connection technology. When assembling prefabricated walls, gaps will appear at the joints of the prefabricated components, allowing external water to enter the prefabricated components through the gaps, thereby affecting the prefabricated components. Usually, sealing strips are installed at the gaps and concrete is poured.

[0003] After searching, the Chinese patent "A vertical seam waterproof structure of prefabricated components with PE rods" authorization announcement number "CN215630723U" realizes the assembly of prefabricated components and anti-seepage treatment of vertical gaps through components, thick-resistant glue, PE rods, a second spring, a moving block, a fourth spring, a limit rod, a second moving plate, a third spring, a first slider and a first spring, effectively avoiding the problem of water seepage in the vertical seams connecting components.

[0004] However, the spring is elastic, and the prefabricated components will vibrate greatly during the pouring of concrete, which can easily cause displacement of the PE rods, thick-resistant glue and prefabricated components, thereby affecting the anti-seepage effect of the vertical joints of the prefabricated components.

[0005] Therefore, a prefabricated component vertical joint anti-seepage structure is proposed to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide a water-proof structure for vertical joints of prefabricated components in order to solve the above-mentioned problem, thereby improving the problem that the prefabricated components produce large vibrations during concrete pouring, which easily leads to displacement of PE rods, thick-resistant glue and prefabricated components.

[0007] The present invention achieves the above-mentioned purpose through the following technical scheme: a prefabricated component vertical seam anti-seepage structure, comprising: two prefabricated panels, PE rods are clamped on opposite sides of the two prefabricated panels; an anti-loosening mechanism, which is arranged on the surface of the prefabricated panels; wherein the anti-loosening mechanism comprises a mold frame clamped on the front end of the prefabricated panels, the surface of the mold frame is clamped on the template, the inner wall of the mold frame is slidably connected to a fixed frame, the upper end of the surface of the fixed frame is clamped on the inner wall of the template, the front end of the mold frame is fixedly connected to a blocking cylinder, the inner wall of the blocking cylinder is rotatably connected to a screw rod, the surface of the screw rod is threadedly connected to a push rod, the bottom end of the push rod is fixedly connected to the top of the fixed frame, and the surface of the PE rod is fixedly connected to two sealing strips. The formwork, template, fixing frame and screw rod are used to realize the fast and stable assembly of two prefabricated panels, and then the two prefabricated panels are stably connected to the PE rod and the sealing strip, thereby avoiding the displacement of the PE rod and the sealing strip when pouring concrete in the gap between the two prefabricated panels, and ensuring the water seepage prevention effect of the vertical joints of the prefabricated components. The blocking cylinder and the push rod are used to protect the screw rod, prevent impurities from adhering to the surface of the screw rod, and ensure that the disassembly and assembly of the formwork and template are more convenient.

[0008] Preferably, the inner wall of the sealing strip is provided with a liquid storage tank, the liquid storage tank is filled with waterproof sealant, the front and rear ends of the sealing strip are provided with a plurality of drainage holes, and the liquid storage tank is connected with the drainage holes. The liquid storage tank and the drainage holes are used to achieve uniform flow of waterproof sealant on the inner side of the sealing strip and the prefabricated board, thereby improving the anti-seepage effect of the sealing strip on the inner side of the prefabricated board.

[0009] Preferably, a sealing frame is fixedly connected to the inner wall of the drainage hole, and a sealing film is fixedly connected to the inner wall of the sealing frame.

[0010] Preferably, the rear end of the mold frame and the front end of the template are fixedly connected with a plurality of puncture needles, and the surface of the puncture needles is slidably connected to the inner wall of the prefabricated board. The puncture needles and the sealing frame are used to puncture the sealing film in the sealing frame, thereby ensuring that the waterproof sealant in the liquid storage tank can flow between the sealing strip and the prefabricated board, and preventing water seepage from the prefabricated board.

[0011] Preferably, two limit blocks are fixedly connected to the surface of the push rod, and the surface of the limit blocks is slidably connected to the inner wall of the blocking cylinder. The limit blocks are used to limit the movement of the push rod, thereby preventing the push rod from slipping when the screw rod drives the push rod to move in the blocking cylinder.

[0012] Preferably, the lower end of the surface of the blocking cylinder is slidably connected to a limit frame, and the surface of the limit frame is clamped to the inner wall of the limit block. The limit frame is used to position the limit block and the push rod, ensuring that the mold frame and the template are fastened to the two prefabricated panels to avoid displacement of the two prefabricated panels during casting.

[0013] Preferably, a blocking block is fixedly connected to the surface of the fixing frame, and the rear end of the blocking block contacts the front end of the formwork. The blocking block is used to block the holes at the front end of the formwork, thereby preventing concrete from flowing into the holes at the front end of the formwork.

[0014] Preferably, the sealing strip is a polyvinyl chloride component.

[0015] The beneficial effects of the present invention are:

[0016] 1. The formwork, template, fixing frame and screw rod are used to realize the fast and stable assembly of two prefabricated panels, and then the two prefabricated panels are stably connected to the PE rod and the sealing strip, thereby avoiding the displacement of the PE rod and the sealing strip when pouring concrete in the gap between the two prefabricated panels, and ensuring the anti-seepage effect of the vertical joints of the prefabricated components. The blocking cylinder and the push rod are used to protect the screw rod, prevent impurities from adhering to the surface of the screw rod, and ensure that the disassembly and assembly of the formwork and template is more convenient;

[0017] 2. By using the liquid storage tank and the drainage hole, the waterproof sealant can flow evenly on the sealing strip and the inner side of the prefabricated board, thereby improving the anti-seepage effect of the sealing strip on the inner side of the prefabricated board.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] When implementing: Figure 1-4 As shown, a prefabricated component vertical joint anti-seepage structure comprises: two prefabricated panels 1, PE rods 2 are clamped on opposite sides of the two prefabricated panels 1; an anti-loosening mechanism 3, which is arranged on the surface of the prefabricated panel 1; wherein the anti-loosening mechanism 3 comprises a mold frame 31 clamped on the front end of the prefabricated panel 1, a template 32 is clamped on the surface of the mold frame 31, a fixed frame 34 is slidably connected to the inner wall of the template 32 on the inner wall of the mold frame 31, the upper end of the surface of the fixed frame 34 is clamped on the inner wall of the template 32, a blocking cylinder 35 is fixedly connected to the front end of the mold frame 31, a screw rod 36 is rotatably connected to the inner wall of the blocking cylinder 35, and a screw rod 36 is threadedly connected to the surface of the screw rod Push rod 37, the bottom end of push rod 37 is fixedly connected to the top of fixing frame 34, two sealing strips 33 are fixedly connected to the surface of PE rod 2, a blocking block 314 is fixedly connected to the surface of fixing frame 34, the rear end of blocking block 314 contacts the front end of mold frame 31, two limit blocks 312 are fixedly connected to the surface of push rod 37, the surface of limit block 312 is slidably connected to the inner wall of blocking cylinder 35, the lower end of the surface of blocking cylinder 35 is slidably connected to limit frame 313, the surface of limit frame 313 is clamped to the inner wall of limit block 312, and the sealing strip 33 is a polyvinyl chloride component.

[0025] When the prefabricated components are assembled into a wall, the prefabricated panel 1 is hoisted to the installation site by a crane for downward installation, so that the prefabricated panel 1 is installed on the corresponding embedded parts, and the PE rod 2 and the sealing strip 33 are clamped on the inner side of the two prefabricated panels 1. Since the sealing strip 33 is a polyvinyl chloride component, the sealing strip 33 has good water-proof performance. The rear end of the mold frame 31 is clamped on the two prefabricated panels 1, so that the rear end of the mold frame 31 is against the front end of the prefabricated panel 1, and the front end of the template 32 is against the rear end of the prefabricated panel 1, so that the inner wall of the template 32 is clamped on the mold frame 31. At this time, the screw rod 36 is rotated, and the rotation of the screw rod 36 drives the push rod 37 and the fixing frame 34 to move upward, so that the fixing frame 34 is clamped in the template 32. , push the limit frame 313 to move in the blocking cylinder 35 and clamp it in the limit block 312. At this time, the formwork 31 and the template 32 are both installed on the two precast panels 1, and the pouring pipe is aligned with the vertical gap at the connection of the two precast panels 1 to pour concrete. Because the formwork 31 and the template 32 are stably installed on the precast panels 1, the two precast panels 1, the PE rod 2 and the sealing strip 33 will not be displaced during the pouring of the concrete. After the poured concrete is formed, the screw rod 36 is rotated to move the fixing frame 34 away from the template 32, and the formwork 31 and the template 32 are pulled to separate them, so that the PE rod 2, cement and the sealing strip 33 are waterproofed in the vertical gap at the connection of the two precast panels 1.

[0026] like Figure 4As shown, the inner wall of the sealing strip 33 is provided with a liquid storage tank 38, and the liquid storage tank 38 is filled with waterproof sealant. The front and rear ends of the sealing strip 33 are provided with a plurality of drainage holes 39, and the liquid storage tank 38 is connected with the drainage holes 39. The inner wall of the drainage holes 39 is fixedly connected with a sealing frame 310, and the inner wall of the sealing frame 310 is fixedly connected with a sealing film. The rear end of the mold frame 31 and the front end of the template 32 are fixedly connected with a plurality of puncture needles 311, and the surface of the puncture needles 311 is slidably connected to the inner wall of the prefabricated board 1. The sealing film is a polypropylene component.

[0027] When the mold frame 31 is stuck in the precast panel 1, it drives the corresponding puncture needle 311 to move in the precast panel 1. The template 32 abuts against the precast panel 1 and drives the corresponding puncture needle 311 to move in the precast panel 1, so that the puncture needle 311 punctures the sealing film in the sealing frame 310, and the waterproof sealant in the liquid storage tank 38 flows out through the drainage hole 39, so that the waterproof sealant flows on the inner side of the precast panel 1 and the surface of the sealing strip 33.

[0028] When the present invention is in use, the prefabricated panel 1 is hoisted to the installation site by a crane for downward installation, so that the prefabricated panel 1 is installed on the corresponding embedded parts, the PE rod 2 and the sealing strip 33 are clamped on the inner sides of the two prefabricated panels 1. Since the sealing strip 33 is a polyvinyl chloride component, the sealing strip 33 has good water-proof performance, the rear end of the mold frame 31 is clamped on the two prefabricated panels 1, the rear end of the mold frame 31 is abutted against the front end of the prefabricated panel 1, the front end of the template 32 is abutted against the rear end of the prefabricated panel 1, the inner wall of the template 32 is clamped on the mold frame 31, the puncture needle 311 is moved to puncture the sealing film in the sealing frame 310, the waterproof sealant in the liquid storage tank 38 flows out through the drainage hole 39, and the waterproof sealant is on the inner side of the prefabricated panel 1 and the sealing strip 33, the push rod 37 and the fixing frame 34 are moved upward by the rotation of the screw rod 36, so that the fixing frame 34 is clamped in the template 32. At this time, the formwork 31 and the template 32 are both installed on the two precast panels 1, and the pouring pipe is aligned with the vertical gap at the connection of the two precast panels 1 to pour concrete. Because the formwork 31 and the template 32 are stably installed on the precast panels 1, the two precast panels 1, the PE rod 2 and the sealing strip 33 will not be displaced during the pouring of the concrete. After the poured concrete is formed, the screw rod 36 is rotated to move the fixing frame 34 away from the template 32, and the formwork 31 and the template 32 are pulled to separate them, so that the PE rod 2, cement and the sealing strip 33 are waterproofed in the vertical gap at the connection of the two precast panels 1.

[0029] It should be noted that the prefabricated board 1, PE rod 2, mold frame 31, template 32, sealing strip 33 and waterproof sealant in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs and will not be described in detail here.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
