Description

Technical Field

[0001] This application relates to the technical field of post-cast strip construction, and in particular to an installation structure for the column head of a post-cast strip steel column frame. 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] A long post-cast strip independent support system in related technologies includes steel columns, formwork, post-cast strip and structural slab. The steel columns are supported on both sides of the post-cast strip. A steel block support is welded to the top surface of the upper end of the steel column. Support feet are welded to the four sides of the lower end of the steel column. The structural slab includes an upper structural slab and a lower structural slab. The upper structural slab is set above the formwork. The steel block support is directly supported below the formwork to support the upper structural slab. The support feet are placed on the lower structural slab.

[0004] Regarding the aforementioned technologies, the inventors discovered that because the post-pouring strip is a secondary formwork, uneven deformation of the concrete structure on both sides of the post-pouring strip will occur. Under the support of the steel block top support, the formwork of the post-pouring strip will not have a tight contact with the original concrete structure surface, resulting in the concrete bulging and leakage problems during concrete pouring. Utility Model Content

[0005] To address the issues of poor contact between the formwork and the concrete surface, which can lead to concrete bulging and grout leakage, this application provides an installation structure for the column head of a post-cast strip steel column frame.

[0006] The installation structure for the column head of a post-cast strip steel column frame provided in this application adopts the following technical solution: An installation structure for the column head of a post-cast strip steel column frame includes a column, a connecting pipe, and a fixing block. The connecting pipe is sleeved on one end of the column, and the fixing block is connected to the end of the connecting pipe away from the column. Support plates are slidably connected to both ends of the fixing block. Multiple top support plates are provided on the support plates, and an adjustment component is provided on the support plates for adjusting the top support plates to abut against the template.

[0007] By adopting the above technical solution, the columns are erected below the formwork. The distance of the support plate extending beyond the fixing block is adjusted according to the width of the post-pouring strip. The top support plate on the support plate provides uniform support to the formwork. Workers adjust the components to tighten the top support plate against the formwork, minimizing gaps between the formwork and the concrete structure. This prevents concrete leakage and bulging after pouring within the formwork. Compared to supporting the formwork with steel blocks, this application uses multiple top support plates for uniform support, allowing workers to adjust each plate individually, thus improving the formwork's support capacity.

[0008] Optionally, the adjustment component includes a connecting block, a first conical block, and a second conical block. The connecting block is connected to the support plate, and a guide block is slidably disposed on the connecting block. One end of the guide block is connected to the top support plate, and one end of the guide block extending into the connecting block is connected to the first conical block. The second conical block is slidably disposed within the connecting block, and the first conical block and the second conical block abut against each other.

[0009] By adopting the above technical solution, the worker drives the second conical block to slide toward the first conical block. Under the pressure of the second conical block, the first conical block causes the guide block to slide out of the connecting block. The top support plate moves away from the connecting block under the action of the guide block, thereby pressing the top support plate against the template.

[0010] Optionally, the connecting block is provided with a threaded block, and a drive rod is rotatably connected to the second conical block. The drive rod is threadedly connected to the threaded block, and a drive block is provided at one end of the drive rod that extends out of the connecting block.

[0011] By adopting the above technical solution, the operator rotates the drive block, which drives the drive rod to rotate. The drive rod is rotatably connected to the threaded block, which causes the drive rod to move the second drive block. This allows the operator to adjust the position of the second drive block by rotating the drive block, thereby adjusting the tightness between the top support plate and the template.

[0012] Optionally, the fixing block is provided with a connecting groove for the support plate to slide, the support plate is provided with a limiting block, the groove wall of the connecting groove is provided with a limiting groove for the limiting block to slide, and the limiting block abuts against the groove wall of the limiting groove.

[0013] By adopting the above technical solution, the support plate slides in the connecting groove, and the limiting block slides in the limiting groove. The limiting groove limits the sliding distance of the limiting block, thereby limiting the distance that the support plate slides out of the fixed block. It also makes it difficult for the support plate to detach from the fixed block, thus improving the stability of the connection between the support plate and the fixed block.

[0014] Optionally, a reinforcing rod is rotatably connected to the connecting pipe, and a fixed pipe is rotatably connected to the support plate, with the reinforcing rod and the fixed pipe being slidably connected.

[0015] By adopting the above technical solution, the reinforcing rod and the connecting pipe are slidably connected. The staff can slide the connecting pipe, thereby causing the connecting pipe to drive the support plate to slide.

[0016] Optionally, the fixing tube is provided with bolts, and the reinforcing rod is provided with a plurality of positioning holes for the bolts to pass through, and the plurality of positioning holes are evenly arranged along the length direction of the reinforcing rod.

[0017] By adopting the above technical solution, the bolts are locked after passing through the positioning holes, thus fixing the connection between the fixing pipe and the reinforcing rod, thereby limiting the distance the support plate can slide out of the fixing block. Furthermore, the mutually fixed fixing pipe and reinforcing rod strengthen the support plate, making it less susceptible to bending deformation due to the weight of the concrete during pouring, thereby improving the overall structural strength and further enhancing the top support plate's ability to support the formwork.

[0018] Optionally, a positioning block is threaded onto the column, and the positioning block abuts against the end of the connecting pipe away from the fixing block.

[0019] By adopting the above technical solution, the positioning block is rotated so that it moves along the height direction of the column, and the positioning block drives the connecting pipe to move, thereby adjusting the overall height of the column and the connecting pipe.

[0020] Optionally, the connecting pipe is provided with a connecting rod, and the column is provided with a sliding groove for the connecting rod to slide. The sliding groove is opened along the height direction of the column, and the connecting rod abuts against the groove wall of the sliding groove.

[0021] By adopting the above technical solution, when the connecting pipe moves, the connecting rod slides within the sliding groove. The sliding groove limits the sliding distance of the connecting rod, making it difficult for the connecting pipe to separate from the column. The connecting rod abuts against the groove wall, making it difficult for the connecting pipe and the column to rotate relative to each other during the movement of the connecting pipe, thereby improving the stability of the connection between the connecting pipe and the column.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting support plates and multiple top support plates on the fixed block, the distance of the support plates extending out of the fixed block is adjusted according to the width of the post-pouring strip. The top support plates on the support plates support the formwork. The workers adjust the components to press the top support plates against the formwork, so that there are not many gaps between the formwork and the concrete structure. This makes it difficult for the concrete to leak out and bulge after it is poured into the formwork.

[0023] 2. By installing reinforcing rods on the connecting pipes and fixing pipes on the support plate, and locking the bolts after they pass through the positioning holes, the distance the support plate slides out of the fixing block can be limited. Furthermore, the mutually fixed fixing pipes and reinforcing rods strengthen the support plate, making it less prone to bending and deformation, thereby improving the overall structural strength and further enhancing the top support plate's ability to support the formwork.

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] This application discloses an installation structure for the column head of a post-cast strip steel column frame. (Refer to...) Figure 1 An installation structure for the column head of a post-cast steel column frame includes a column 1, a connecting pipe 2, and a fixing block 3. The column 1 is fixedly installed on the ground, the connecting pipe 2 is sleeved on the column 1, and the fixing block 3 is fixedly connected to the end of the connecting pipe 2 away from the column 1. Connecting grooves 33 are provided at both ends of the fixing block 3, and a support plate 31 is slidably installed within the connecting groove 33. Multiple top support plates 32 for pressing against the formwork are connected to the support plate 31. In this embodiment, four top support plates 32 are provided, with two top support plates 32 on each support plate 31, and the two top support plates 32 are arranged opposite each other along the width direction of the support plate 31.

[0032] Reference Figure 1 and Figure 2 A positioning block 11 is threaded onto the column 1, and the positioning block 11 abuts against the end of the connecting pipe 2 away from the fixing block 3. A connecting rod 23 is fixedly connected to the connecting pipe 2, and a sliding groove 12 is provided on the column 1 for the connecting rod 23 to pass through. The sliding groove 12 is opened along the height direction of the column 1. The operator adjusts the overall height of the column 1 and the connecting pipe 2 by rotating the positioning block 11 according to the distance between the bottom surface and the template. During the rotation of the positioning block 11, the positioning block 11 drives the connecting pipe 2 to move, causing the connecting rod 23 to slide within the sliding groove 12. The sliding groove 12 limits the movement distance of the connecting rod 23, thus making it difficult for the connecting pipe 2 and the column 1 to separate. Furthermore, the connection between the connecting rod 23 and the groove wall of the sliding groove 12 prevents relative rotation between the connecting pipe 2 and the column 1 during the sliding process of the connecting rod 23, thereby improving the stability of the connection between the column 1 and the connecting pipe 2.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A limiting block 34 is fixedly connected to the support plate 31. A limiting groove 35 is provided on the groove wall of the connecting groove 33 for the limiting block 34 to slide. The limiting groove 35 is opened along the length direction of the support plate 31, and the limiting block 34 abuts against the groove wall of the limiting groove 35. Moreover, neither end of the limiting groove 35 is connected to the end face of the support plate 31, so that the limiting groove 35 limits the sliding distance of the limiting block 34, thereby limiting the distance of the support plate 31 extending out of the fixed block 3, making it difficult for the support plate 31 to separate from the fixed block 3.

[0034] Reference Figure 3 and Figure 4 An adjustment assembly 4 is provided on the support plate 31. The adjustment assembly 4 is used to adjust the tightness between the top support plate 32 and the template. The adjustment assembly 4 includes a connecting block 41, a first conical block 42, a second conical block 43, a guide block 44, and a drive rod 46. The connecting block 41 is fixedly connected to the support plate 31. The first conical block 42 and the second conical block 43 are both slidably disposed within the connecting block 41. The first conical block 42 and the second conical block 43 are arranged in a perpendicular state, and the conical surfaces of the first conical block 42 and the second conical block 43 abut against each other. The guide block 44 is slidably connected to the connecting block 41. One end of the guide block 44 extending into the connecting block 41 is fixedly connected to the first conical block 42, and the other end of the guide block 44 extending out of the connecting block 41 is fixedly connected to the top support plate 32. The drive rod 46 is rotatably connected to the second conical block 43. A threaded block 45 that is threadedly connected to the drive rod 46 is fixedly connected to the connecting block 41, and a drive block 47 is fixedly connected to the end of the drive rod 46 extending out of the connecting block 41.

[0035] Workers rotate the drive block 47, causing the drive rod 46 to slide the second conical block 43 toward the first conical block 42. Under the pressure of the second conical block 43, the first conical block 42 drives the guide block 44 to slide, causing the top support plate 32 to move away from the connecting block 41 under the action of the guide block 44. This allows the top support plate 32 to press firmly against the template, making it less likely for gaps to appear between the template and the concrete structure. Consequently, after concrete is poured inside the template, it is less likely for the concrete to leak or bulge outwards.

[0036] Reference Figure 1 A reinforcing rod 21 is rotatably connected to the connecting pipe 2, and a fixing pipe 36 is rotatably connected to the support plate 31. The reinforcing rod 21 and the fixing pipe 36 are slidably connected. In this embodiment, there are two reinforcing rods 21 and two fixing pipes 36, and each fixing pipe 36 is located at the end of the support plate 31 away from the fixing block 3.

[0037] Reference Figure 5 Bolts 37 are fixedly connected to the fixed tube 36, and a number of positioning holes 22 are opened on the reinforcing rod 21 for the bolts 37 to pass through. The number of positioning holes 22 are evenly arranged along the length direction of the reinforcing rod 21.

[0038] Workers slide the connecting pipe 2, causing the support plate 31 to slide and adjust the distance the support plate 31 extends beyond the fixing block 3. Bolt 37 passes through the positioning hole 22 and is then tightened, fixing the connection between the fixing pipe 36 and the reinforcing rod 21, thus preventing the position of the support block from easily changing. The mutually fixed fixing pipe 36 and reinforcing rod 21 strengthen the support plate 31, making it less prone to bending deformation under the weight of concrete during pouring, thereby improving the overall structural strength and further enhancing the support capacity of the top support plate 32 for the formwork.

[0039] The implementation principle of the installation structure of the post-cast strip steel column frame column head in this application embodiment is as follows: First, the worker adjusts the overall height of the column 1 and the connecting pipe 2 according to the distance from the bottom surface to the formwork using the positioning block 11. Then, according to the width of the post-cast strip, the distance of the support plate 31 extending out of the fixing block 3 is adjusted so that the top support plate 32 evenly supports the formwork. The bolts 37 are passed through the corresponding positioning holes 22 on the reinforcing rod 21 and locked, so that the reinforcing rod 21 and the fixing pipe 36 are fixedly connected. Next, by rotating the drive block 47, the top support plate 32 is pressed against the formwork, and finally, the concrete pouring work can be carried out.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
