Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a pre-buried structure for civil construction. Background Art

[0002] "Civil construction": refers to the construction of civil engineering projects, covering the construction of buildings, structures, and engineering objects in facilities and places within the scope of many projects, such as houses, roads, railways, airports, bridges, water conservancy, ports, tunnels, water supply and drainage, and protection, etc., on the ground, underground, on land, on water, and underwater. It includes various technical activities such as survey, design, construction, maintenance, and management during the construction process. Embedded parts are components pre-installed or buried in concealed projects, which are components placed during the pouring of structures. They are used for overlap when building superstructures to facilitate the installation and fixation of external engineering equipment foundations. Embedded parts are mostly made of metal. Under the action of embedded parts, non-structural components such as steel plates and keels can be fixed, which can greatly improve the safety of buildings.

[0003] The comparative document CN216516191U discloses a pre-embedded equipment for civil engineering construction. The above document realizes the adjustment of the height of the embedded parts. The fixed screw plate on the surface of the screw rod can realize the fixation of the load-bearing platform. The slot on the surface of the screw groove is socketed with the fixed tube. The internally threaded fixed rod makes the fixed curved gasket press against the template wall through the top block. The casting groove opened on the surface of the screw groove can allow the concrete to enter the interior of the screw groove from the casting groove for further fixation after the concrete is poured.

[0004] In the above scheme, when the equipment needs to be fixed in the template, the fixing rod is driven to rotate outward by rotating the top block, so that the fixing rod can drive the fixed curved gaskets on both sides to stick to the inner wall of the template. In the above scheme, the rotation of the two fixing rods is achieved by manually rotating the top block, which is inconvenient to operate and difficult to manually control the moving distance of the fixing rods on both sides, which often leads to different extension distances of the two fixing rods, causing the predetermined position of the embedded parts to shift. In the above scheme, in order to make the equipment more stable, concrete is poured into the inside through the casting trough after the equipment adjustment is completed to achieve further fixation. However, since the casting trough is located on the side wall of the sleeve, in order to achieve the fixation between the lifting device and the sleeve, the casting trough needs to be blocked during and after casting to prevent concrete from flowing out, which is very inconvenient to operate. A solution to the above problems is proposed below. Utility Model Content

[0005] The purpose of the utility model is to provide a pre-buried structure for civil engineering construction, which solves the problems in the prior art proposed by the above-mentioned background technology that the adjustment of the fixed rod needs to be done manually, which is not conducive to adjustment, and the casting trough needs to be blocked all the time to prevent the concrete from flowing out when pouring concrete, which is inconvenient to operate.

DETAILED DESCRIPTION OF THE EMBODIMENT

[0022] As shown in Figures 1 to 6 , a civil engineering construction embedded structure includes an embedded part 1 and a load-bearing platform 2 fixedly installed on the lower surface of the embedded part 1. A first screw 3 is rotatably provided at the bottom of the load-bearing platform 2. One end of the first screw 3 away from the load-bearing platform 2 is provided with a sleeve 4. A threaded hole 5 is opened at the top of the sleeve 4. The first screw 3 is in threaded cooperation with the threaded hole 5. The bottom of the sleeve 4 is fixedly connected with a supporting bottom plate 23. When it is necessary to install the embedded part 1, the sleeve 4 can be first installed into the template. The sleeve 4 can increase the contact area at the bottom through the supporting bottom plate 23, thereby better supporting the sleeve 4.

[0023] Two connecting cylinders 6 are fixed on the bottom side wall of the sleeve 4. Slide plates 7 are slidably arranged in both connecting cylinders 6. A second screw rod 8 is arranged on the slide plate 7 in a threaded fit. A cavity 9 is formed inside the sleeve 4. The connecting cylinder 6 is communicated with the cavity 9. A driving assembly 10 for driving the two second screw rods 8 to rotate is arranged in the cavity 9. When the sleeve 4 is installed in the template, the driving assembly 10 can be started, and the second screw rods 8 are driven to rotate through the driving assembly 10, so as to facilitate the subsequent support and fixation of the sleeve 4.

[0024] The driving assembly 10 includes a first bevel gear 12, two second bevel gears 13 and a third bevel gear 14. A first connecting rod 15 is rotatably arranged at the bottom of the cavity 9. The first bevel gear 12 is fixed on the top of the first connecting rod 15. One end of the second screw rod 8 is rotatably arranged in the cavity 9, and the second bevel gear 13 is fixed on the second screw rod 8. Each second bevel gear 13 is in meshing engagement with the first bevel gear 12. A second connecting rod 16 is rotatably arranged on the sleeve 4. One end of the second connecting rod 16 penetrates through the sleeve 4 and is fixed to the third bevel gear 14. The third bevel gear 14 is in meshing engagement with the first bevel gear 12. A rotating handwheel 17 is fixed to the other end of the second connecting rod 16. When it is necessary to drive the second screw rod 8 to rotate, the rotating handwheel 17 can be manually rotated. The rotating handwheel 17 drives the second connecting rod 16 to rotate. The third bevel gear 14 can be rotated through the second connecting rod 16. The rotation of the third bevel gear 14 drives the first bevel gear 12 meshing with it to rotate. During the rotation of the first bevel gear 12, the two second bevel gears 13 meshing with it are driven to rotate, and the rotation of the two second bevel gears 13 realizes the rotation of the two second screw rods 8.

[0025] A fixing rod 11 is fixed to the end of the slide plate 7 away from the sleeve 4. One end of the fixing rod 11 close to the slide plate 7 is of a hollow structure. The second screw rod 8 is rotatably arranged in the fixing rod 11. During the rotation of the second screw rod 8, the slide plate 7 in threaded fit with it slides inside the connecting cylinder 6. The inside of the connecting cylinder 6 is of a square groove structure. By arranging the inside of the connecting cylinder 6 as a square groove structure, the rotation of the slide plate 7 can be limited, so that the slide plate 7 can only slide linearly inside the connecting cylinder 6 through the second screw rod 8. During the sliding of the slide plate 7, the fixing rod 11 is pushed to move. A top block 19 is fixed to the end of the fixing rod 11 away from the slider. A fixing gasket 20 is fixed to one end of the top block 19. During the movement of the fixing rod 11, the top block 19 and the fixing gasket 20 move together. The installation of the top block 19 can better install the fixing gasket 20. The continuous movement of the fixing gasket 20 enables the fixing gasket 20 to contact the inner wall of the template. The support and fixation of the equipment are realized through the fixing gaskets 20 on both sides. Each fixing rod 11 realizes automatic movement through the movement of the slider, without manual rotation one by one, improving the installation efficiency, and the distances extended by the fixing rods 11 are the same, which is convenient for better positioning of the equipment.

[0026] The embedded part 1 adjusts its height by rotating the first screw 3. A wide groove is formed at the bottom of the load-bearing platform 2, and a bearing is installed in the wide groove. A connecting plate 21 is installed at the top of the first screw 3. The bearing is divided into an inner ring and an outer ring. The connecting plate 21 is fixed to the inner ring of the bearing. When it is necessary to adjust the height of the embedded part 1 to adjust the embedded part 1 to a specified height, the first screw 3 can be rotated. The first screw 3 will drive the inner ring of the bearing to rotate. During the rotation of the first screw 3, it will gradually extend from the inside of the sleeve 4, so as to drive the height adjustment of the load-bearing platform 2. The load-bearing platform 2 will drive the embedded part 1 to rise and fall, so as to adjust the height of the embedded part 1.

[0027] Two first connecting holes 18 are formed at the top of the sleeve 4. The first connecting holes 18 are located on the side wall of the threaded hole 5. A second connecting hole 22 communicating with the cavity 9 is also formed on the side wall of the sleeve 4. The second connecting hole 22 corresponds to the upper side wall of the cavity 9. When the sleeve 4 is fixed and the height adjustment of the embedded part 1 is completed, concrete can be poured into the inside of the sleeve 4 through the first connecting holes 18 and the second connecting hole 22, so as to better fix the equipment and improve the strength of the equipment. The concrete enters the threaded hole 5 through the two first connecting holes 18. The concrete enters from the top, so that it can better contact the first screw 3. And the concrete is poured into the inside from the top, so that the operator does not need to always block the pouring port. When the concrete pouring is completed, the pouring equipment can be directly removed without always blocking the pouring port and waiting for the concrete to solidify, which improves the pouring efficiency and is convenient for better construction. The concrete enters the inside of the cavity 9 through the second connecting hole 22. The second connecting hole 22 is located at the upper end of the driving component 10. When the concrete enters the cavity 9 through the second connecting hole 22, the driving component 10 can be directly fixed, so that the fixing gasket 20 will not move later and is convenient for better supporting and fixing.

[0028] Working principle: When it is necessary to install the embedded part 1, the sleeve 4 can be first installed in the formwork. The sleeve 4 is supported and fixed by the supporting bottom plate 23 at the bottom. After the sleeve 4 is installed in the formwork, the driving component 10 is first adjusted. By starting the driving component 10, the second screw 8 is driven to rotate. The second screw 8 will drive the slide plate 7 that is in threaded cooperation with it to slide in the connecting cylinder 6. The slide plate 7 can thus push the fixing rod 11 to move linearly. The fixing rod 11 will drive the top block 19 and the fixing cushion block to move. Through the fixing cushion block, contact with the inner wall of the formwork is realized. Through the fixing cushion blocks on both sides, the sleeve 4 is fixed. After the sleeve 4 is fixed, the height of the embedded part 1 can be adjusted by rotating the first screw 3, so that the embedded part 1 can be adjusted to a specified height. When the sleeve 4 is fixed and the height adjustment of the embedded part 1 is completed, concrete can be poured into the inside of the sleeve 4 through the first connecting holes 18 and the second connecting hole 22, so as to better fix the equipment and improve the strength of the equipment.
