Description

Technical Field

[0001] This utility model belongs to the field of precast wall panel technology, and in particular relates to connecting components for precast concrete wall panels. Background Technology

[0002] During the connection process at the bottom of precast concrete wall panels, a grouting sleeve is generally embedded in the base, and ribbed steel bars extend from the bottom of the wall panel. High-strength grout fills the gap between the sleeve and the steel bars to form a rigid connection. In order to improve the stability of the filling material at the connection position of the concrete wall panel during the solidification process, we designed a precast concrete wall panel connection component, which adopts the method of slotting and planting thick steel bars, and is combined with external tensioning to ensure the stability of the concrete wall panel. Utility Model Content

[0003] The purpose of this utility model is to provide a connecting component for precast concrete wall panels, which uses a grooved method for inserting thick reinforcing bars and external tensioning to ensure the stability of the concrete wall panels, thereby solving the aforementioned technical problems.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a precast concrete wall panel connecting component, which includes multiple rectangular cavities I equally spaced on the top of the concrete support, the inner cavity of each rectangular cavity I is provided with a thick steel bar embedded in the concrete support, a precast concrete slab is placed on the top of the concrete support, multiple rectangular cavities II aligned with the rectangular cavities I are opened at the bottom of the precast concrete slab, a grouting port is opened on one side of the inner cavity of each rectangular cavity II, an insertion hole for inserting the thick steel bar is opened at the top of the inner cavity of each rectangular cavity II, two symmetrical U-shaped steel bars I are installed on the side of the precast concrete slab, two symmetrical U-shaped steel bars II are installed on the top of the concrete support through collision bolts, and a tensioning component is provided between the U-shaped steel bars II and the U-shaped steel bars I.

[0005] Preferably, the tensioning assembly includes a tube body rotatably connected to two surfaces of the U-shaped steel bar, a threaded sleeve rotatably connected to the end of the tube body, a threaded rod threadedly connected to the inner cavity of the threaded sleeve, and a hook fixedly connected to the end of the threaded rod to one surface of the U-shaped steel bar.

[0006] Preferably, the inner cavity of the grouting port is provided with a wooden plug.

[0007] Preferably, an overflow port communicating with the inner cavity of the rectangular cavity is provided above the inner cavity of the grouting port.

[0008] Preferably, two symmetrical internally threaded pipes are pre-embedded on the side of the precast concrete slab, and a screw rod is threaded into the inner cavity of the internally threaded pipe. A fixing plate is sleeved on the surface of the screw rod, and the U-shaped steel bar is welded to one side of the fixing plate.

[0009] The beneficial effects of this utility model are: 1. This utility model involves hoisting a precast concrete slab onto the top of a concrete support, allowing thick steel bars to be inserted into the inner cavity of the insertion hole for positioning and reinforcement. A U-shaped steel bar is installed on the side of the precast concrete slab, and a second U-shaped steel bar is installed on the concrete support. Then, a tensioning assembly is used to tighten the second U-shaped steel bar and the first U-shaped steel bar to prevent the precast concrete slab from tilting to the side. Next, filler material is injected into the inner cavities of the second rectangular cavity and the first rectangular cavity through the grouting port. During this process, the thick steel bars and the tensioning assembly ensure the stability of the precast concrete slab. This achieves the stability of the concrete wall panel by using a slotted and thick steel bar insertion method combined with external tensioning. 2. This utility model, through the combined use of an internally threaded tube, a screw rod, and a fixing plate, allows the fixing plate to be rotated after the filling material in the inner cavities of rectangular cavity one and rectangular cavity two has solidified, thereby removing the screw rod and the fixing plate and thus removing the U-shaped steel bar used for temporary fixing, making it convenient for reuse.

[0013] Figure 1-4This invention illustrates a precast concrete wall panel connecting component according to an embodiment of the present invention. It includes multiple rectangular cavities 3 evenly spaced at the top of a concrete support 1. The inner cavity of each rectangular cavity 3 contains a thick steel bar 4 embedded within the concrete support 1. A precast concrete slab 2 is placed on top of the concrete support 1. Multiple rectangular cavities 5 aligned with the rectangular cavities 3 are located at the bottom of the precast concrete slab 2. A grouting port 6 is located on one side of the inner cavity of each rectangular cavity 5. A wooden plug 11 is placed inside the grouting port 6. An overflow port 12 communicating with the inner cavity of each rectangular cavity 5 is located above the grouting port 6. An insertion hole 7 for inserting the thick steel bar 4 is located at the top of the inner cavity of each rectangular cavity 5. Two symmetrical U-shaped steel bars 8 are installed on the side of the precast concrete slab 2. Two symmetrical internally threaded pipes 13 are embedded on the side of the precast concrete slab 2. A screw rod 14 is threadedly connected to the inner cavity of each internally threaded pipe 13. A fixing plate 15 is fitted onto the surface of the screw rod 14. A U-shaped steel bar 8 is welded to one side of the fixing plate 15. Through the cooperation of the internal threaded tube 13, the screw rod 14, and the fixing plate 15, after the filling material in the inner cavity of the rectangular cavity 1 3 and the rectangular cavity 2 5 has solidified, the fixing plate 15 can be rotated to remove the screw rod 14 and the fixing plate 15, thereby removing the U-shaped steel bar 8 used for temporary fixation for easy reuse. Two symmetrical U-shaped steel bars 2 9 are installed on the top of the concrete bearing 1 by collision bolts. A tensioning assembly 10 is provided between the U-shaped steel bars 2 9 and the U-shaped steel bar 1 8. The tensioning assembly 10 includes a tube body 101 rotatably connected to the surface of the U-shaped steel bar 2 9. A threaded sleeve 102 is rotatably connected to the end of the tube body 101. A threaded rod 103 is threadedly connected to the inner cavity of the threaded sleeve 102. A hook 104 hooked to the surface of the U-shaped steel bar 1 8 is fixedly connected to the end of the threaded rod 103.

[0014] Working Principle: In use, this utility model involves hoisting the precast concrete slab 2 onto the top of the concrete support 1. The thick steel bars 4 embedded in the inner cavity of the rectangular cavity 3 on the concrete support 1 are inserted into the insertion holes 7 in the inner cavity of the rectangular cavity 25 on the precast concrete slab 2, thus positioning and reinforcing the precast concrete slab 2. A seal is provided around the bottom of the precast concrete slab 2 where it contacts the concrete support 1. A screw rod 14 is inserted into the inner cavity of the fixing plate 15 on the side of the precast concrete slab 2 and screwed into the inner cavity of the internally threaded tube 13. A U-shaped steel bar 8 is installed on the side of the precast concrete slab 2. Then, a U-shaped steel bar 9 is installed on the concrete support 1. Finally, the tensioning assembly 10 is rotated on the surface of the U-shaped steel bar 9. Rotate the threaded sleeve 102 to extend and shorten the threaded rod 103, and hook the hook 104 at the end of the threaded rod 103 onto the U-shaped steel bar 8. Then, rotate the threaded sleeve 102 again to move the threaded rod 103 into the pipe body 101, so that the U-shaped steel bar 9 and the U-shaped steel bar 8 are in a tensioned state to prevent the precast concrete slab 2 from tilting to the side. Then, inject filler into the inner cavity of the rectangular cavity 5 and the rectangular cavity 3 through the grouting port 6 until it overflows from the overflow port 12. Insert the wooden plug 11 into the inner cavity of the grouting port 6 and the overflow port 12. During this process, the thick steel bar 4 and the tensioning component 10 ensure the stability of the precast concrete slab 2. After the filler has solidified, remove the tensioning component 10 for reuse.

[0015] In summary: This precast concrete wall panel connecting component, by hoisting the precast concrete slab 2 onto the top of the concrete support 1, allows the thick steel bar 4 to be inserted into the cavity of the insertion hole 7 for positioning and reinforcement. U-shaped steel bars 8 are installed on the side of the precast concrete slab 2, and then U-shaped steel bars 9 are installed on the concrete support 1. The tensioning assembly 10 then tightens the U-shaped steel bars 9 and 8 to prevent the precast concrete slab 2 from shifting sideways. Next, filling material is injected into the cavities of the rectangular cavities 2 and 3 through the grouting port 6. During this process, the thick steel bar 4 and the tensioning assembly 10 ensure the stability of the precast concrete slab 2. This achieves the stability of the concrete wall panel by using a slotted reinforcement method combined with external tensioning.
