Abstract
Description
Technical Field
[0001] This utility model relates to the field of aerogel foam concrete technology, specifically to a leak-proof aerogel foam concrete precast component. Background Technology
[0002] Aerogel foam concrete is concrete material mixed with foaming agent and aerogel particles. It requires the use of a foaming machine to process the foaming agent and mix it thoroughly with the concrete slurry and aerogel particles. Then, the finished product is injected into the cavity formed by the template through the pump of the foaming machine.
[0003] The solidified composite material has the advantages of low thermal conductivity, high strength and light weight, strong heat insulation effect and few cracks. It is suitable for making exterior walls, connecting columns, roofs and other panels. In order to adapt to the size of the installation space of the panels, the prefabricated parts need to be spliced to increase the area of the prefabricated parts. However, the existence of gaps will lead to leakage and water seepage inside the building.
[0004] Now, a novel type of leak-resistant aerogel foam concrete precast component is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a leak-proof aerogel foam concrete precast component to solve the problem of easy water seepage in the gaps of precast components mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a precast aerogel foam concrete component with anti-seepage properties, comprising a main column and a clamping rod. The clamping rod is fixed between the upper and lower parts at the center of the left side of the main column, and clamping strips are longitudinally fixed on the front, back, and left sides of the clamping rod surface. A splicing groove is provided between the upper and lower parts at the center of the right side of the main column, and clamping strips are longitudinally fixed on the front, back, and left sides inside the splicing groove. A U-shaped cavity is formed between the clamping rod and the splicing groove, and a grout filling layer is provided in the U-shaped cavity.
[0007] As a further technical solution of this utility model, the clamp is embedded in the splicing groove, and the clamp and the splicing groove are on the same vertical plane.
[0008] As a further technical solution of this utility model, the first card strip is embedded between adjacent second card strips, and the first card strip and the second card strip have the same specifications.
[0009] As a further technical solution of this utility model, vertical grooves are provided longitudinally at the four corners of the main column body, and keels are fixedly inserted in the vertical grooves. Circular grooves are provided at the top and bottom of the vertical grooves, and blocking pieces are fixed in the circular grooves. A slurry filling layer is provided between the keel and the blocking pieces.
[0010] As a further technical solution of this utility model, the blocking pieces are symmetrically attached to the upper and lower parts of the keel, and the blocking pieces and the keel are arranged in concentric circles.
[0011] As a further technical solution of this utility model, a cylindrical groove is provided above the center of the main column, and a limiting block is fixed at the bottom of the cylindrical groove. A pre-embedded pipe is fixed between the top of the limiting block and the cylindrical groove, and five sets of rings are fixed inside the pre-embedded pipe. Plastic sheets are fixed around the inner wall of the rings, and holes are formed at the center between the plastic sheets. A slot is provided below the cylindrical groove, and a pad is fixed on the top surface of the main column.
[0012] Compared with the prior art, the beneficial effects of this utility model are: the anti-leakage aerogel foam concrete precast component not only prevents water seepage in the precast component and improves the strength of the internal structure of the precast component, but also facilitates the laying of wire harnesses.
[0013] By fixing a clamp rod between the upper and lower parts at the center of the left side of the main column, several main columns can be assembled together to form a wall panel. Simply align the clamp rod on the left side of the main column with the splicing groove on the right side, and insert the adjacent main columns from top to bottom so that the clamp rod is embedded in the splicing groove. The first clamp strip on the surface of the clamp rod is also embedded between the second clamp strip inside the splicing groove. Then, pour the first grout filling layer into the concave cavity formed between the clamp rod and the splicing groove to prevent the assembled main columns from separating and to prevent liquid from leaking out of the gaps.
[0014] By fixing and inserting keels in the vertical grooves, when pouring aerogel foam concrete material into the mold cavity, vertical steel keels are inserted into the four corners respectively. After the main column solidifies, the keels can be fixed in the vertical grooves around the perimeter. Since the length of the keel is slightly shorter than the vertical groove, the vertical groove and the upper and lower parts of the keel form circular grooves respectively. After attaching the plug, the second layer of grout is poured in to seal the vertical groove, prevent the keel from detaching from the main column, and improve the internal structural strength of the material.
[0015] By fixing a pre-embedded tube between the top of the limiting block and the cylindrical groove, a pad is used as a buffer when assembling the main column. The top of the pre-embedded tube of the adjacent main column is inserted into the slot, so that the lower pre-embedded tube fits against the bottom of the upper limiting block. Each pre-embedded tube is connected to the limiting block, allowing the wire harness to pass through the ring for laying. Multiple plastic pieces in the ring can form holes of variable size, increasing the friction between the wire harness and the wire harness skin, preventing the wire harness from shaking or colliding with the pre-embedded tube, and maintaining the vertical state of the wire harness in the pre-embedded tube.

[0023] Please see Figure 1-5 An embodiment of this utility model is provided: a precast aerogel foam concrete component with anti-seepage properties, including a main column 1 and a clamping rod 9. The clamping rod 9 is fixed between the upper and lower parts at the center of the left side of the main column 1, and clamping strips 7 are fixed longitudinally on the front, back and left sides of the surface of the clamping rod 9. A splicing groove 10 is provided between the upper and lower parts at the center of the right side of the main column 1, and clamping strips 11 are fixed longitudinally on the front, back and left sides inside the splicing groove 10. A concave cavity 13 is formed between the clamping rod 9 and the splicing groove 10, and a slurry filling layer 12 is provided in the concave cavity 13.
[0024] The locking rod 9 is embedded in the splicing groove 10, and the locking rod 9 and the splicing groove 10 are on the same vertical plane. The locking strip 7 is embedded between the adjacent locking strip 11, and the locking strip 7 and the locking strip 11 have the same specifications.
[0025] Specifically, such as Figure 1 and Figure 2As shown, several main columns 1 can be assembled together to form a wall panel. Simply align the locking rod 9 on the left side of the main column 1 with the splicing groove 10 on the right side, and insert the adjacent main columns 1 from top to bottom, so that the locking rod 9 is embedded in the splicing groove 10. The locking strip 7 on the surface of the locking rod 9 is also embedded between the locking strip 11 inside the splicing groove 10. Then, pour the grout filling layer 12 into the concave cavity 13 formed between the locking rod 9 and the splicing groove 10 to prevent the assembled main columns 1 from separating.
[0026] Vertical grooves 2 are provided at the four corners inside the main column 1, and keel 3 is fixedly inserted in the vertical grooves 2. Circular grooves 14 are provided at the top and bottom of the vertical grooves 2, and blocking pieces 4 are fixed in the circular grooves 14. A slurry filling layer 2 15 is provided between the keel 3 and the blocking pieces 4. The blocking pieces 4 are symmetrically attached to the upper and lower parts of the keel 3, and the blocking pieces 4 and the keel 3 are arranged in concentric circles.
[0027] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when pouring aerogel foam concrete material into the mold cavity, vertical steel keels 3 are inserted into the four corners respectively. After the main column 1 solidifies, the keels 3 are fixed in the vertical grooves 2 around the perimeter. Since the length of the keel 3 is slightly shorter than the vertical groove 2, the vertical groove 2 and the upper and lower parts of the keel 3 form circular grooves 14 respectively. After attaching the plug 4, the second grout filling layer 15 is poured in to seal the vertical groove 2 and protect the keel 3.
[0028] A cylindrical groove 18 is provided above the center of the main column 1, and a limiting block 16 is fixed at the bottom of the cylindrical groove 18. A pre-embedded pipe 6 is fixed between the top of the limiting block 16 and the cylindrical groove 18, and five sets of rings 17 are fixed inside the pre-embedded pipe 6. Plastic sheets 19 are fixed around the inner wall of the rings 17, and holes 20 are formed at the center between the plastic sheets 19. A slot 5 is provided below the cylindrical groove 18, and a pad 8 is fixed on the top surface of the main column 1.
[0029] Specifically, such as Figure 1 , Figure 4 and Figure 5 As shown, when assembling the upper and lower main columns 1, a pad 8 is used as a buffer. The top of the pre-embedded tube 6 of the adjacent main column 1 is inserted into the slot 5, so that the lower pre-embedded tube 6 fits against the bottom of the upper limiting block 16, and each pre-embedded tube 6 is connected to the limiting block 16, allowing the wire harness to pass through the ring 17 for laying. Multiple plastic pieces 19 in the ring 17 can form holes 20 of variable size, increasing the friction between the wire harness and the wire harness skin and preventing the wire harness from loosening.
[0030] Working Principle: When using this utility model, firstly, when pouring aerogel foam concrete material into the mold cavity, vertical steel keels 3 are inserted into the four corners. After the main column 1 solidifies, the keels 3 are fixed in the vertical grooves 2 around the perimeter. Since the length of the keel 3 is slightly shorter than the vertical groove 2, the vertical groove 2 and the upper and lower parts of the keel 3 form circular grooves 14 respectively. After attaching the plug 4, the second grout filling layer 15 is poured in to seal the vertical groove 2 and prevent the keel 3 from detaching from the main column 1. Several main columns 1 can be assembled together to form a wall panel. Simply align the clamping rod 9 on the left side of the main column 1 with the splicing groove 10 on the right side, and insert the adjacent main columns 1 from top to bottom, so that the clamping rod 9 is embedded in the splicing groove 10. The clamping strip 7 on the surface of the clamping rod 9 is also embedded between the clamping strip 11 inside the splicing groove 10. Then insert the clamping rod 9... The cavity 13 formed between the splicing groove 10 and the concave cavity 13 is filled with grout filling layer 12 to prevent the main column 1 from separating after assembly. When assembling the main column 1, the pad 8 serves as a buffer. The top of the pre-embedded pipe 6 of the adjacent main column 1 is inserted into the slot 5, so that the lower pre-embedded pipe 6 fits against the bottom of the upper limiting block 16, and each pre-embedded pipe 6 is connected to the limiting block 16, allowing the wire harness to pass through the ring 17 for laying. Multiple plastic pieces 19 in the ring 17 can form holes 20 of variable size to increase the friction between the wire harness and the wire harness skin for fixation. In this case, the main column 1, the clamp 9, the clamp strip 1 7 and the clamp strip 2 11 are all made of the same aerogel foam concrete material, and the grout filling layer 12 and the grout filling layer 2 15 are also made of the same cement material.
