Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of post-cast sealing plate anchoring structure, and in particular to a post-cast sealing plate anchoring structure for window tops. Background Technology
[0002] Post-cast slab sealing is a common construction method in building engineering, mainly used for beams, columns, and other components in concrete structures. During construction, a portion of concrete is first poured into the formwork. After the concrete reaches a certain strength, a protective material (such as asphalt felt or film) is placed on its surface, and then the remaining concrete is poured on top to form a monolithic component. Because of this two-stage pouring method, the entire component is more robust and dense, improving the overall quality and durability of the concrete. Post-cast slab sealing simplifies the construction process and facilitates control of parameters such as temperature and humidity during concrete pouring, thus improving construction efficiency. However, existing post-cast slab sealing slabs often lack support during pouring, affecting stability. Therefore, we introduce a post-cast slab sealing anchoring structure for window roofs. Utility Model Content
[0003] The main purpose of this utility model is to provide an anchoring structure for the post-cast sealing plate of the window top, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] An anchoring structure for a post-cast sealing plate at the top of a window includes a concrete layer. A reserved opening is provided at the front end of the concrete layer. Four main anchoring steel bars are installed and connected to the groove wall of the reserved opening. Side anchoring steel bars are installed and connected to the left and right groove walls of the reserved opening. Two of the side anchoring steel bars are staggered. All four main anchoring steel bars are located above the two side anchoring steel bars. A formwork is provided at the lower end of the concrete layer, and a support device is installed and connected to the lower end of the formwork.
[0006] Preferably, the support device includes a lifting rod, with U-shaped locking blocks movably connected to the lower left and lower right ends of the lifting rod. Both U-shaped locking blocks are U-shaped structures, and threaded rods are fixedly connected to the lower ends of both U-shaped locking blocks. Lower sleeves are threadedly connected to the lower parts of the outer surfaces of both threaded rods, and bases are fixedly connected to the lower ends of both lower sleeves.
[0007] Preferably, the lifting rod is located at the lower part of the template and is in contact with the template.
[0008] Preferably, the diameters of the two lower sleeves are both larger than the diameters of the two threaded rods, and the upper ends of the two lower sleeves are each provided with threaded holes.
[0009] Preferably, the reserved opening has four No. 1 reserved holes on the rear wall of the groove, and the left and right walls of the reserved opening each have No. 2 reserved holes.
[0010] Preferably, the height of the two second reserved holes is lower than the height of the four first reserved holes.
[0011] Preferably, the diameter of each of the four main anchoring bars is smaller than the diameter of the four No. 1 reserved holes, and the diameter of each of the two side anchoring bars is smaller than the diameter of the two No. 2 reserved holes.
[0012] This utility model has the following beneficial effects:
[0013] In this invention, a support device is installed to hold the lifting rod against the lower end of the template. A U-shaped clamp is inserted into the lifting rod, and the U-shaped clamp holds the lifting rod tightly. Since a lower sleeve is fitted onto the outer surface of the threaded rod at the lower end of the U-shaped clamp, rotating the lower sleeve can extend the threaded rod and the lower sleeve. After the lower sleeve contacts the ground, it works with the threaded rod and the U-shaped clamp to support the lifting rod, allowing the lifting rod to press the template tightly, thus facilitating the use of the template and improving the stability during pouring.

[0022] Please see Figure 1-4 This utility model provides a technical solution:
[0023] An anchoring structure for a post-cast sealing plate at the top of a window includes a concrete layer 1. A reserved opening 3 is opened at the front end of the concrete layer 1. Four main anchoring steel bars 4 are installed and connected to the groove wall of the reserved opening 3. Side anchoring steel bars 2 are installed and connected to the left and right groove walls of the reserved opening 3. The two side anchoring steel bars 2 are staggered. The four main anchoring steel bars 4 are all located above the two side anchoring steel bars 2. A formwork 6 is set at the lower end of the concrete layer 1. A support device 5 is installed and connected to the lower end of the formwork 6.
[0024] In this embodiment, the support device 5 includes a lifting rod 51. U-shaped locking blocks 52 are movably connected to the lower left and lower right portions of the lifting rod 51. Both U-shaped locking blocks 52 are U-shaped structures. A threaded rod 55 is fixedly connected to the lower end of each of the two U-shaped locking blocks 52. A lower sleeve 53 is threadedly connected to the lower part of the outer surface of each of the two threaded rods 55. A base 54 is fixedly connected to the lower end of each of the two lower sleeves 53. The lifting rod 51 is located below the template 6 and contacts the template 6. The two lower sleeves... The diameter of 53 is greater than the diameter of the two threaded rods 55, and the upper ends of the two lower sleeves 53 are both threaded holes 531; the rear groove wall of the reserved opening 3 has four No. 1 reserved holes 31, and the left and right groove walls of the reserved opening 3 have No. 2 reserved holes 32; the height of the two No. 2 reserved holes 32 is lower than the height of the four No. 1 reserved holes 31; the diameter of the four main anchoring steel bars 4 is smaller than the diameter of the four No. 1 reserved holes 31, and the diameter of the two side anchoring steel bars 2 is smaller than the diameter of the two No. 2 reserved holes 32.
[0025] The above method involves precisely placing the anchoring agent into four pre-drilled No. 1 reserved holes 31 and two No. 2 reserved holes 32. Four main anchoring steel bars 4 are inserted one-to-one into the four No. 1 reserved holes 31, and two side anchoring steel bars 2 are inserted into the two No. 2 reserved holes 32. After the formwork 6 is placed, the lower sleeve 53 is rotated to extend the threaded rod 55 and the lower sleeve 53 as a whole, causing the U-shaped locking block 52 to clamp the lifting rod 51. All three components work together to support the formwork 6 before concrete pouring. Because the formwork 6 is adequately supported and fixed, the stability during pouring is significantly improved, thus ensuring pouring quality and reducing potential risks during construction.
[0026] It should be noted that this utility model describes an anchoring structure for a post-cast sealing plate at the top of a window. First, the anchoring agent is precisely placed into four pre-drilled No. 1 reserved holes 31 and two No. 2 reserved holes 32. Next, four main anchoring steel bars 4 are inserted one-to-one into the four No. 1 reserved holes 31. These steel bars serve as the main supporting structure. Simultaneously, two side anchoring steel bars 2 are inserted into the two No. 2 reserved holes 32, which provide auxiliary support and stability to the entire structure. Then, the lifting rod 51 is firmly abutted against the lower end face of the formwork 6. Immediately afterwards, a U-shaped clamp 52 is inserted and connected to the lifting rod 51. The shape of the U-shaped clamp 52 allows it to tightly hold the lifting rod 51. An adjustable lower sleeve 53 is fitted onto the outer surface of the threaded rod 55 at the lower end of the U-shaped clamp 52. Construction workers can easily extend the threaded rod 55 and the lower sleeve 53 by simply rotating the lower sleeve 53. As the lower sleeve 53 gradually contacts and compacts the ground, it, together with the threaded rod 55 and the U-shaped clamp 52, forms a stable support, effectively supporting the lifting rod 51. This ensures that the formwork 6 is firmly held in place, preventing displacement or deformation during use. Finally, after all the support structures are confirmed to be correct, concrete pouring can begin. Because the formwork 6 is adequately supported and fixed, the stability during the pouring process is significantly improved, thus ensuring the quality of the pouring and reducing potential risks during construction.
