Description

Technical Field

[0001] This invention relates to the technical field of post-cast strip sealing equipment, specifically a post-cast strip sealing device for concrete. Background Technology

[0002] A post-cast strip is a concrete strip left at the corresponding position of the foundation slab, wall, or beam in the construction process to prevent harmful cracks that may occur in the reinforced concrete structure due to uneven shrinkage or settlement. This is done in accordance with the design or construction specifications.

[0003] During the pouring of the post-pouring strip, to prevent concrete from overflowing outside the pouring area, edge sealing plates are required on both sides of the strip. These edge sealing plates ensure the concrete is tightly poured inside the strip. Existing edge sealing plates are typically made of a single piece of wood. Positioning devices are used at the edges of the wood to firmly attach it to the edge of the post-pouring strip. However, the large size of the wood makes transportation and storage inconvenient, especially for high-altitude operations. Fixing such large pieces requires multiple workers, which is inconvenient and dangerous. Furthermore, fixed-point edge fixing cannot be adjusted according to the actual environment. The limited number of positioning points and the difficulty in adjustment can easily lead to insufficient adhesion in some areas. Summary of the Invention

[0014] 1.

[0015] 2. In the process of splicing the lower sealing plates in this invention, the lower connecting frame can be rotated at the corresponding position for each set of lower sealing plates, so that the elastic low rod on the lower connecting frame abuts against the corresponding lower sealing plate. Thus, each set of lower sealing plates is provided with an elastic low rod, and the lower connecting frame can rotate around the upper elastic abutment rod. This allows the contact point of the elastic abutment rod on each set of lower sealing plates to be adjusted as needed, increasing the number and degree of freedom of the fixed points on the sealing plate. This ensures that each set of lower sealing plates can fit tightly against the edge of the post-pouring strip, reducing the possibility of concrete overflow during pouring.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-5 This invention provides a technical solution: a concrete post-pouring strip sealing device, comprising a concrete wall 1 and a positioning seat 3. The concrete wall 1 is arranged parallel to each other to form a post-pouring strip. A steel reinforcement frame 5 is arranged between the concrete wall 1s. The positioning seat 3 is located on the upper surface of the concrete wall 1. A bidirectional threaded rod 2 is rotatably installed inside the positioning seat 3. Both ends of the bidirectional threaded rod 2 are threadedly connected to an upper sealing plate 6. A limit groove 32 is formed on the lower surface of the upper sealing plate 6. A lower sealing plate 7 is slidably connected inside the limit groove 32. A limit block 31 is fixedly installed on the upper surface of the lower sealing plate 7. The lower sealing plate 7... A limiting groove 32 is provided on the surface, which matches the limiting block 31. A connecting plate 4 is fixedly installed on the upper end of the upper edge sealing plate 6. A rotating shaft 11 is fixedly installed on the connecting plate 4. An upper connecting frame 9 is rotatably installed on the rotating shaft 11. An elastic abutment 12 is fixedly installed on the lower end of the upper connecting frame 9. A lower connecting frame 8 is rotatably installed on the elastic abutment 12. A locking device is provided at the lower end of the upper connecting frame 9. The upper connecting frame 9 and the lower connecting frame 8 cooperate with the locking device to form a pressing assembly. The pressing assembly abuts against the surface of the lower edge sealing plate 7 and the abutment point on the surface of the lower edge sealing plate 7 can be freely adjusted.

[0026] During operation, the positioning seat 3 is fixed to the upper surface of the concrete wall 1, and the bidirectional threaded rod 2 is driven to rotate, causing the upper sealing plates 6 at both ends of the bidirectional threaded rod 2 to move towards the concrete wall 1 until the upper sealing plates 6 are flush with the surface of the concrete wall 1. After determining the position of the upper sealing plates 6, the elastic low rod at the bottom of the upper connecting frame 9 abuts against the surface of the upper sealing plates 6, making the upper sealing plates 6 fit more tightly with the post-pouring strip. Then, through the cooperation of the limiting block 31 and the limiting groove 32, the lower sealing plates 7 are continuously spliced ​​below the upper sealing plates 6 until the lowest lower sealing plate 7 can be connected. The edge of the post-pouring strip is completely covered. The edge banding plate consists of an upper edge banding plate 6 and multiple sets of lower edge banding plates 7. During transportation and storage, the upper edge banding plate 6 and the lower edge banding plate 7 can be disassembled. At the same time, the positioning device for the edge banding plate is also composed of an upper connecting frame 9 and a lower connecting frame 8 that can be rotated and spliced ​​together. It can be folded and stored, making the transportation of the edge banding equipment more convenient. In addition, when working at heights, the edge banding plate can be transported to higher places more conveniently without the trouble of transporting large-volume plates by multiple people. This reduces the danger during the installation process, and the edge banding installation can be carried out by a single person, reducing the difficulties in the installation process. During the splicing process, each set of lower sealing plates 7 can rotate the corresponding lower connecting frame 8, so that the elastic low rod on the lower connecting frame 8 abuts against the corresponding lower sealing plate 7. Thus, each set of lower sealing plates 7 is equipped with an elastic low rod, and the lower connecting frame 8 can rotate around the upper elastic abutment rod 12. This allows the contact point of the elastic abutment rod 12 on each set of lower sealing plates 7 to be adjusted as needed, increasing the number and degree of freedom of the fixed points on the sealing plate. This ensures that each set of lower sealing plates 7 can fit tightly against the edge of the post-pouring strip, reducing the possibility of concrete overflow during pouring.

[0027] In this invention, after the upper edge sealing plate 6 is fixed in position, the elastic low rod at the bottom of the upper connecting frame 9 abuts against the surface of the upper edge sealing plate 6, making the upper edge sealing plate 6 fit more tightly with the post-pouring strip. Then, through the cooperation of the limiting block 31 and the limiting groove 32, the lower edge sealing plate 7 is continuously spliced ​​below the upper edge sealing plate 6 until the lower edge sealing plate 7 at the bottom can completely cover the edge of the post-pouring strip. The edge sealing plate is composed of the upper edge sealing plate 6 and multiple sets of lower edge sealing plates 7. During transportation and storage, the upper edge sealing plate 6 and the lower edge sealing plate 7 can be separated. At the same time, the positioning device of the edge sealing plate is also formed by the rotation and splicing of the upper connecting frame 9 and the lower connecting frame 8, which can be folded and stored, making the transportation of the edge sealing equipment more convenient. In addition, when working at height, the edge sealing plate can be transported to a high place more conveniently, without the trouble of multiple people cooperating to transport large-volume plates, reducing the danger during the installation process. The edge sealing installation can be carried out by a single person, reducing the difficulty of the installation process.

[0028] In this invention, during the splicing of the lower sealing plates, the lower connecting frame 8 can be rotated at the corresponding position for each set of lower sealing plates, so that the elastic low rod on the lower connecting frame 8 abuts against the corresponding lower sealing plate. Thus, each set of lower sealing plates is provided with an elastic low rod, and the lower connecting frame 8 can rotate around the upper elastic abutment rod 12. This allows the contact point of the elastic abutment rod 12 on each set of lower sealing plates to be adjusted as needed, increasing the number and degree of freedom of the fixed points on the sealing plate, thereby ensuring that each set of lower sealing plates can be tightly attached to the edge of the post-pouring strip, reducing the possibility of concrete overflow during pouring.

[0029] As a further embodiment of the present invention, the extrusion assembly consists of multiple sets of lower connecting frames 8, multiple sets of elastic abutments 12, and an upper connecting frame 9. One end of the lower connecting frame 8 is fixedly installed with an elastic abutment 12. Locking devices are fixedly installed on the surfaces of the lower connecting frame 8 and the upper connecting frame 9 near the elastic abutment 12. The end of the lower connecting frame 8 that fixes the elastic abutment 12 is rotatably connected to the adjacent elastic abutment 12. One end of the locking device is fixedly connected to the upper end of the adjacent lower connecting frame 8. The upper connecting frame 9 is provided with two sets, and a limit spring 10 is fixedly installed between the two sets of upper connecting frames 9.

[0030] During operation, after fixing the upper connecting frame 9 and the first set of lower sealing plates 7, the control knob 34 on the upper connecting frame 9 is rotated (the rotation of the control knob 34 drives the active disc 35 to rotate, the rotation of the active disc 35 drives the insert rod 42 to rotate, the rotation of the insert rod 42 presses the inner wall of the insert groove 45, thereby causing the movable part 43 to press the elastic part 44, causing both sets of movable parts to move towards the intermediate shaft 41, thereby causing the locking teeth on the movable part 43 to disengage from the ratchet teeth on the locking part 38, thus allowing the rotation of the insert rod 42 to drive the driven disc 40 to rotate, the rotation of the driven disc 40 to drive the connecting column 39 to rotate, the rotation of the connecting column 39 to drive the lower connecting frame 8 fixed thereto to rotate, the lower connecting frame... After rotating to the designated position, stop rotating the control knob 34. At this time, the squeezing effect of the insert rod 42 on the insert groove 45 is small, and the locking teeth of the moving parts 43 at both ends re-embed into the ratchet. The ratchet locks the position of the driven plate 40, restricting the mutual locking of the driven plates 40, thereby restricting the rotation of the corresponding lower connecting frame 8, so that the lower connecting frame 8 is stably in the set position. This drives the first set of upper connecting frames 9 to rotate. The upper connecting frame 9 rotates around the elastic low rod on the upper sealing plate 6, thereby adjusting the position of the elastic low rod on the first set of lower connecting frames 8 on the first set of lower sealing plates 7. This allows the user to adjust the contact position of the sealing according to the actual environmental conditions, increasing the variability and applicability of the device.

[0031] As a further embodiment of the present invention, the locking device includes a movable frame 33, which is fixedly installed on the upper connecting frame 9 and the lower connecting frame 8 near the end of the elastic abutment 12.

A connecting tube 28 is fixedly installed on one side of the extension tube 22. A suction component 27 is fixedly installed on the end of the connecting tube 28 away from the extension tube 22.

[0035] During operation, the drive motor drives the side limiting shaft 20 to rotate. The rotation of the side limiting shaft 20 drives the active bevel gear 24 to rotate and drives the connecting shaft 19 to rotate through the transmission component 29. The rotation of the active bevel gear 24 drives the driven bevel gear 25 to rotate. The rotation of the driven bevel gear 25 drives the active gear 23 to rotate (the active gear 23 is a half-axle gear). The teeth of the active gear 23 drive the driven gear 21 to rotate. The rotation of the driven gear 21 drives the control valve 26 to rotate. The rotation of the control valve 26 connects the extension pipe 22 and the connecting pipe 28. The suction component 27 vacuums the suction cup 14 through the connecting pipe 28, the extension pipe 22 and the suction pipe 17, so that the suction cup 14 and the concrete wall 1 are in negative pressure, thereby positioning it to adhere to the upper surface of the concrete wall 1.
