Abstract
Description
Technical Field
[0001] This utility model relates to the field of template support equipment technology, and in particular to a formwork support structure for expansion joints. Background Technology
[0002] During engineering construction, structural design often requires the inclusion of narrow joints: When there are significant differences in the number of stories, the load, or the compressibility of the foundation between different parts of the superstructure, uneven settlement may occur. Joints are needed to divide the structure into several parts, ensuring more uniform settlement in each part and preventing additional stress in the structure. These joints are called "settlement joints." Expansion joints are also used: If a building's plan dimensions are too long, thermal expansion and contraction may lead to excessive temperature stress in the structure. Joints are needed along a certain length to divide the building into several parts; these are expansion joints. However, currently, long expansion joints between adjacent units in a residential building often have narrow internal spaces, making it inconvenient to support the formwork inside the shear walls on both sides.
[0003] In the prior art, for example, Chinese invention patent CN101949213B discloses a special support system for formwork of building structure expansion joints. The expansion joint formwork includes formwork on both sides inside the expansion joint and formwork on the outside of the walls on both sides of the expansion joint. The formwork on the outside of the walls on both sides of the expansion joint is provided with secondary back ribs, and the secondary back ribs are provided with main back ribs. Tie bolts are provided between the main back ribs on the outside of the walls on both sides of the expansion joint. When this device is in use, it is fixed by tie bolts. The bolts need to pass through the so-called formwork to fix the formwork. However, after the concrete is poured, the bolt holes need to be sealed. This requires sealing treatment of the bolt holes, which increases the cost. In addition, the sealing treatment of the bolt holes is complicated, and there is a certain risk of water leakage after long-term use.
[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
[0005] To address the aforementioned shortcomings, the purpose of this utility model is to provide a support structure for expansion joint templates. This structure can support the template inside the expansion joint by setting an internal support structure, eliminating the need for tie bolts passing through the template and thus eliminating the need for bolt holes. This reduces the cost of sealing bolt holes and the risk of leakage.
[0006] To achieve the above objectives, this utility model provides a support structure for expansion joint templates, comprising: A plurality of side support beams are fixedly connected to the side wall of the expansion joint template. The side support beams are provided with tension bolts at both ends of the expansion joint template. The side support beams are pressed against the side wall of the expansion joint template by the tension of the tension bolts. Several clamping components are disposed inside the expansion joint. Each clamping component has adjusting sleeves at both ends that are screwed onto the two side support beams. The clamping components clamp the inner side plate of the expansion joint template under the action of the two adjusting sleeves.
[0007] In one embodiment, the clamping assembly includes: At least two sets of support rods are rotatably connected to the adjusting sleeve, and the support rods in the same set include two support rods, which are respectively connected to two adjusting sleeves; A pressure plate rotatably connected to the support rod is rotatably connected to the support rod in the same group. The change in the distance between the two adjusting sleeves further adjusts the position of the pressure plate.
[0008] In one embodiment, the side support beam has a threaded hole, and the outside of the adjusting sleeve has a threaded portion that mates with the threaded hole. The two threaded portions rotate in opposite directions, and when the two adjusting sleeves rotate in the same direction, the adjusting sleeves move towards each other.
[0009] In one embodiment, an annular groove is provided at one end of the inner side of the adjusting sleeve, an annular sleeve is fitted on the outside of the annular groove, and two opposing hinge seats are provided on the outer side wall of the annular sleeve, and the support rod is rotatably connected to the hinge seats.
[0010] In one embodiment, the inner side of the clamping plate is provided with a plurality of evenly arranged rotating holes, and the support rod is installed with the rotating holes by a pivot pin.
[0011] In one embodiment, an adjusting member is also included. The adjusting sleeve has an adjusting hole inside, and the adjusting member is inserted into the adjusting hole. At the same time, the rotation of the adjusting member drives the adjusting sleeve to rotate.
[0012] In one embodiment, the outer wall of the adjusting hole is provided with a limiting groove, and the adjusting member includes an adjusting shaft inserted into the adjusting hole, and the outer side of the adjusting shaft is provided with a limiting protrusion corresponding to the limiting groove.
[0013] In one embodiment, one end of the adjusting shaft is provided with an operating handle.
[0014] This utility model provides a support structure for expansion joint templates, including: several side support beams, which are fixedly connected to the side walls of the expansion joint template. By fixing and tightening the side support beams, the side walls of the expansion joint template can be fixed, thus effectively securing the expansion joint template. Each side support beam has tension bolts at both ends of the expansion joint template. The tension of the tension bolts compresses the side walls of the expansion joint template, ensuring the tensioning effect of the side support beams and effectively fixing the side walls of the expansion joint template. This fixes the template to form the internal concrete pouring area, which then solidifies to form a concrete wall. Several clamping components are disposed inside the expansion joint, and are aligned using the clamping components. The template on the side wall of the expansion joint is tightened and fixed. The two ends of the clamping assembly are provided with adjusting sleeves screwed onto the two side support beams. By setting the adjusting sleeves, the state of the clamping assembly can be effectively controlled. Under the action of the two adjusting sleeves, the clamping assembly presses the inner plate of the expansion joint template, thereby ensuring the fixation of the inner plate of the expansion joint and preventing leakage of concrete from the template's interface, thus avoiding bulging or material leakage. In summary, the technical effect of this utility model is that by setting an internal support structure, the template inside the expansion joint can be supported without the need for tie bolts passing through the template, thereby eliminating the need for bolt holes and reducing the cost and risk of leakage when sealing bolt holes.

[0019] See Figure 1 and Figure 2This utility model provides a support structure for expansion joint templates. The support structure includes several side support beams 2, which are fixedly connected to the side walls of the expansion joint template 6. By fixing and tightening the side support beams 2, the side walls of the expansion joint template 6 can be fixed, thus effectively securing the template. Tensioning bolts are provided at both ends of the side support beams 2 of the expansion joint template 6. The tension of the tensioning bolts on the side support beams 2 compresses the side walls of the expansion joint template 6, ensuring the tightening effect and effectively fixing the side walls of the template. This fixes the template to form the internal concrete pouring area, which then solidifies to form a concrete wall 1. Several clamping components are also provided inside the expansion joint 7, which, through the clamping components, press against the side walls of the expansion joint template 6. The template on the side wall of the expansion joint 7 is tightened and fixed. The two ends of the clamping assembly are equipped with adjusting sleeves 4 screwed onto the two side support beams 2. By setting the adjusting sleeves 4, the state of the clamping assembly can be effectively controlled. Under the action of the two adjusting sleeves 4, the clamping assembly presses the inner plate of the expansion joint template 6, thereby ensuring the fixation of the inner plate of the expansion joint 7 and preventing the concrete inside the expansion joint template 6 from leaking at the interface of the template, resulting in bulging or leakage. In order to ensure the supporting force of the side support beams 2, the support beams can be set as I-beams or other structures with high support effect, thereby ensuring the support effect of the side support beams 2 and preventing deformation in the middle of the support beams. Alternatively, a support rod can be set in the middle of the side support beams 2 and directly slid inward to ensure the support effect of the support rod.
[0020] In one embodiment, in order to better press and fix the side wall of the template inside the expansion joint 7, the pressing assembly includes: at least two sets of support rods 5 rotatably connected to the adjusting sleeve 4. The template inside the expansion joint 7 is supported and fixed by setting the support rods 5. The support rods 5 in the same set include two support rods 5, and the two support rods 5 are respectively connected to two adjusting sleeves 4. Thus, by adjusting the position and distance of the two adjusting sleeves 4, the state of the support rods 5 can be adjusted, thereby adjusting the supporting force of the template. The clamping plate 3, which is rotatably connected to the support rod 5, can fix the side wall of the template inside the expansion joint 7, thus providing firm support. The clamping plate 3 is rotatably connected to the support rod 5 in the same group, so that the angle of the support rod 5 can be adjusted while the adjusting sleeve 4 moves, thereby expanding the support of the clamping plate 3 so that the outer side of the clamping plate 3 abuts against the template that needs to be clamped, thus effectively fixing the template. The change in the distance between the two adjusting sleeves 4 further adjusts the position of the clamping plate 3, fixing the template.
[0021] In addition, in order to adjust the movement of the adjusting sleeve 4, a threaded hole is provided on the side support beam 2, and a threaded part 42 that mates with the threaded hole is provided on the outside of the adjusting sleeve 4. The two threaded parts 42 rotate in opposite directions. When the two adjusting sleeves 4 rotate in the same direction, the adjusting sleeves 4 move towards each other. Thus, when adjusting the adjusting sleeve 4, the adjusting sleeve 4 can press the support rod 5 to support it outward or rotate it inward, thereby realizing the parallel adjustment of the pressure plate 3.
[0022] Furthermore, to ensure that the rotation of the adjusting sleeve 4 does not interfere with the support rod 5, an annular groove 41 is provided at one end of the inner side of the adjusting sleeve 4, and an annular sleeve 8 is fitted on the outside of the annular groove 41. Two opposing hinge seats are provided on the outer wall of the annular sleeve 8, and the support rod 5 is rotatably connected to the hinge seats. Several evenly arranged rotating holes are provided on the inner side of the pressure plate 3. The support rod 5 is installed with the rotating holes through a shaft pin, which facilitates the adjustment of the position between the support rod 5 and the pressure plate 3, thereby supporting and fixing expansion joints 7 of different widths.
[0023] Also see Figure 3 and Figure 4 In order to control the synchronous rotation of the two adjusting sleeves 4, the device is also provided with an adjusting component. The adjusting sleeve 4 has an adjusting hole 43 inside, and the adjusting component is inserted into the adjusting hole 43. At the same time, the rotation of the adjusting component drives the adjusting sleeve 4 to rotate. The outer wall of the adjusting hole 43 has a limiting groove 44. The adjusting component includes an adjusting shaft 83 inserted into the adjusting hole 43. The outer side of the adjusting shaft 83 has a limiting protrusion 82 corresponding to the limiting groove 44, which ensures that when the adjusting shaft 83 drives the adjusting sleeve 4 to rotate, the adjusting sleeve 4 can move on the adjusting shaft 83. When driving, the adjusting shaft 83 is inserted into both adjusting sleeves 4 at the same time, so that the two adjusting sleeves 4 can be driven to rotate synchronously at the same time. One end of the adjusting shaft 83 is provided with an operating handle 81, which makes it convenient for the operator to drive the adjusting shaft 83 to rotate.
[0024] When using, combine Figures 1-4 First, the expansion joint template 6 is erected, and then the support beam is fixed to the side wall of the expansion joint template 6. At this time, the support beam can be fixed and tightened by means of a tensioning bolt or other mechanism (existing technology, not described in detail). Then, the adjusting part is inserted into the adjusting hole 43 inside the adjusting sleeve 4. Then, by turning the operating handle 81, the adjusting sleeve 4 is moved and thus comes into contact with the inner wall of the expansion joint 7. The threaded part 42 of the adjusting sleeve 4 and the threaded hole cooperate to provide the clamping force to the inner wall of the expansion joint 7, thereby effectively fixing the expansion joint 7. After the application is completed, the clamping component can be disassembled by pulling the shaft pin out of the support rod 5 and the clamping plate 3.
[0025] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
