Description

Technical Field

[0001] This invention relates to the field of adjustable precast component joint technology, and more specifically to an adjustable precast component joint that can improve construction quality. Background Technology

[0002] The connection of prefabricated component nodes is an important technical aspect for ensuring the quality and safety of prefabricated buildings. Different types of prefabricated component nodes are designed, but the node design does not take much into consideration from the perspective of ease of installation. That is, there is a lack of proactive design and quality control. Good design directly affects the quality level of node formation, and complex node design also seriously affects its installation operation, and even leads to human-caused damage, resulting in insufficient promotion and application of prefabricated buildings.

[0003] Existing precast component node connections suffer from problems such as complex installation, low construction efficiency, and difficulty in quality control. For example, patent 2020110585341 discloses a single-sided overlapping L-shaped precast component node and construction method; patent 2017103217470 discloses a novel vertical precast component node connection method; patent 2020112430612 discloses a method for solving the blockage of connecting cavities in prefabricated concrete buildings; and patent 2020110585498 discloses a single-sided overlapping U-shaped precast component node.

[0004] Therefore, in order to address the above problems, there is an urgent need for an adjustable precast component node that can improve construction quality. Summary of the Invention

The lower end of the upper connecting frame and the upper end of the lower connecting frame are hinged together by a shaft, and the hinge point is on the same straight line as the midpoint of the intersection of the first inclined surface and the second inclined surface.

[0012] Furthermore, the upper connecting cylinder can move left and right via the upper adjusting component; the lower connecting cylinder can move left and right via the lower adjusting component.

[0013] Furthermore, the upper adjustment assembly includes an upper adjustment screw and an upper fixing screw sleeve. The two upper adjustment screws are symmetrically arranged on both sides of the upper adjustment sleeve. The other end of the upper adjustment screw is threaded through the upper connecting frame and connected to the upper fixing screw sleeve. The upper adjustment screw can abut against the upper adjustment sleeve by rotating it. The lower adjustment assembly includes a lower adjustment screw and a lower fixing screw sleeve. The two lower adjustment screws are symmetrically arranged on both sides of the lower adjustment sleeve.

[0021] like Figure 1-5 As shown, an adjustable precast component node that can improve construction quality includes an upper precast component 10, a lower precast component 20, and a connecting component 30. The upper precast component 10 and the lower precast component 20 are connected by a connecting component 30, and the angle and longitudinal relative position between the upper precast component 10 and the lower precast component 20 can be adjusted by the connecting component 30; the opposite ends of the upper precast component 10 and the lower precast component 20 are used to connect with the reinforcing bars.

[0022] As a preferred embodiment of the above technical solution, the upper prefabricated component 10 includes an upper connecting cylinder 100, and the lower end face of the upper connecting cylinder 100 is a first inclined surface 101; The lower prefabricated component 20 includes a lower connecting cylinder 200, the upper end face of which is a second inclined surface 201; and the first inclined surface 101 matches the second inclined surface 201.

[0025] As a preferred embodiment of the above technical solution, the upper prefabricated component 10 further includes an upper adjusting sleeve 102 and an upper fastener 103.

The lower adjusting sleeve 202 and the lower connecting cylinder 200 are fixed by the lower fastener 203. The angle of the upper connecting cylinder 100 or the lower connecting cylinder 200 can be adjusted by rotating or bending the upper connecting cylinder 100 or the lower connecting cylinder 200. In addition, the upper connecting cylinder 100 and the lower connecting cylinder 200 can move up and down along the upper adjusting sleeve 102 and the lower adjusting sleeve 202, respectively.

[0026] In the above technical solution, the upper connecting cylinder is fixed inside the upper adjusting sleeve by rotating it to a preset angle and then tightening it with the upper fastener; the upper fastener is a screw.

[0031] As a preferred embodiment of the above technical solution, the upper connecting cylinder 100 can move left and right via the upper adjusting component; the lower connecting cylinder 200 can move left and right via the lower adjusting component.

The lower adjustment assembly includes a lower adjustment screw 305 and a lower fixing screw sleeve 306.

[0033] In the above technical solution, the position of the upper connecting cylinder is changed and fixed by turning the upper adjusting screws on both sides of the upper adjusting sleeve; the position of the lower connecting cylinder is changed and fixed by turning the lower adjusting screws on both sides of the lower adjusting sleeve.

[0034] As a preferred embodiment of the above technical solution, the upper adjustment assembly further includes an upper limit screw 309 and an upper nut 310. The two upper limit screws 309 are symmetrically installed on the front and rear sides of the upper adjustment sleeve 102.

[0035] In the above technical solution, by loosening the upper nut and the lower nut, the upper limit screw and the lower limit screw slide along the upper guide groove and the lower guide groove respectively. Then, by tightening the upper nut and the lower nut, the upper limit screw and the lower limit screw are fixed, thereby realizing the adjustment of the position of the upper adjustment sleeve and the lower adjustment sleeve.

[0036] The upper connecting cylinder 100 and the lower connecting cylinder 200 are respectively provided with an upper material guide channel 307 and a lower material guide channel 308. Both the upper and lower material guide channels are inclined, and the inclination angles can be in the same direction or centrally symmetrical.

[0037] The upper connecting cylinder 100 and the lower connecting cylinder 200 are also provided with ear brackets to facilitate the rotation or movement of the upper connecting cylinder and the lower connecting cylinder.

[0038] The implementation principle of this invention is as follows: like Figure 4 As shown, insert the reinforcing bar 40 into the upper connecting cylinder, and gradually close the upper notch by rotating the upper fixing nut, thereby fixing the reinforcing bar into the upper connecting cylinder. Similarly, insert the reinforcing bar 40 into the lower connecting cylinder, and gradually close the lower notch by rotating the lower fixing nut, thereby fixing the reinforcing bar into the lower connecting cylinder.

[0039] like Figure 5 As shown, by pulling the upper connecting cylinder upwards and then rotating it to a preset angle of 180°, bending it 90°, and then moving the upper connecting cylinder closer to the lower connecting cylinder, the first and second inclined surfaces are brought into contact. Finally, the upper connecting cylinder is tightened using the upper fastener, resulting in the desired effect. Figure 5 The structure shown is designed to accommodate different straight-line and right-angle connections to meet construction requirements. Furthermore, the upper and lower adjustment components address the "difficulty in alignment" issue; and the upper and lower material guide channels 307 and 308 address the "difficulty in ensuring full grouting."
