Description

Technical Field

[0001] This invention relates to the field of precast concrete wall panel connection structures, specifically a steel connection component for concrete wall panels that allows for rapid alignment. Background Technology

[0002] In prefabricated concrete shear wall structures, vertical joints between precast concrete wall panels need to be connected. Currently, the common practice in engineering is to use a connection equivalent to a secondary casting connection. This connection method involves leaving lapped reinforcing bars from bottom to top on the side of the precast concrete wall panel, commonly known as "beard bars". On-site, vertical reinforcing bars and lapped stirrups are arranged and tied in the lap section of the "beard bars", and then formwork is erected and concrete is poured. This connection method is the one adopted in JGJ1-2014 "Technical Specification for Prefabricated Concrete Structures" and GB / T51231-2016 "Technical Standard for Prefabricated Concrete Buildings".

[0003] In prefabricated wall panel components, where the connection method is equivalent to cast-in-place secondary casting, holes or grooves must be drilled in the side formwork according to design requirements to allow the "bearded reinforcement" to pass through. Due to inadequate design or lax control during wall panel prefabrication, the position and dimensions of the "bearded reinforcement" may be incorrect or significantly flawed. This can lead to collisions during installation, which are difficult to correct on-site and cannot be quickly aligned. Consequently, it often requires forced installation, sometimes even cutting the reinforcement, creating structural safety hazards. For multi-story prefabricated concrete shear wall structures, the stress is much lower than in high-rise structures, and relatively simpler connection methods can be used between wall panels.

[0004] For example, a Chinese patent discloses a "Tensioning Rope Connecting Assembly for Connecting Concrete Wall Panels and its Usage Method" (Patent No.: CN201810576480.4). This patent includes: a first connector, prefabricated in a first precast concrete wall panel, with a first fixing part on the first connector; a second connector, prefabricated in a second precast concrete wall panel, with a second fixing part on the second connector; a rope tensioning structure including a rope and two tensioning members, the two tensioning members being respectively installed at both ends of the rope; the two tensioning members being respectively fastened to the corresponding first and second fixing parts, and the two tensioning members pulling the two ends of the rope in opposite directions to tension the rope; and concrete being poured on-site in the gap between the first and second precast concrete wall panels after being connected by the tensioning rope connecting assembly. The tensioning rope connecting assembly of this invention can replace the reinforcing steel bars in the cast-in-place connection area between two precast concrete wall panels.

[0005] However, in practice, the aforementioned patent only uses ropes as an internal framework to support the cast-in-place concrete between the two wall panels. Even with the limitations of the joint template, problems can easily arise where the concrete cannot be properly attached. Furthermore, due to insufficient concrete support at the joint, cracks are more likely to appear there over time than in other areas. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the present invention provides a solution that solves the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a steel structure connector for a concrete wall panel capable of rapid alignment, installed in the cast-in-place connection area between two walls. It includes a rope assembly and two anchor assemblies. The two anchor assemblies are prefabricated in the two walls respectively, and the rope assembly is linked to the two anchor assemblies. Each anchor assembly includes an anchor member, a connecting cylinder, an outer sleeve, and a long bolt. The anchor member is installed within the wall, and both the outer sleeve and the connecting cylinder are connected to the anchor member. The outer sleeve and the connecting cylinder communicate with each other, and the outer sleeve and the connecting cylinder are respectively provided with an internal thread one and an internal thread two. The long bolt is threaded to the internal thread one, and the long bolt is adapted to the opening of the connecting cylinder. The long bolt is linked to the rope assembly.

[0008] Preferably, the anchor assembly further includes a short bolt, a connecting pivot, and a nut. The short bolt is threaded into an internal thread, and the opening extends through the short bolt along its length. The connecting pivot is pivotally connected to the end of the short bolt furthest from the nut. The nut is threaded into a long bolt.

[0009] Preferably, the rope assembly includes a main rope member and two auxiliary rope members. The main rope member and the two auxiliary rope members pass through the opening and are connected to the connecting rotatable base, with the two auxiliary rope members being symmetrical about the main rope member.

[0010] Preferably, the rope assembly further includes two main loops and two auxiliary loops. The two main loops are disposed on the main body of the main rope component located between the two walls, and the two auxiliary loops are disposed on the two auxiliary rope components respectively.

[0011] Preferably, the rope assembly further includes a support for branching the rope. The main rope member and the two auxiliary rope members all pass through the support and extend to the outside of the wall.

[0012] By adopting the above technical solution, the present invention has the following advantages compared with the prior art: This quick-aligning concrete wall panel steel structure connector utilizes a combination of rope assembly anchors, connecting cylinders, outer sleeves, and long bolts. Because the present invention uses rope assembly connections, it is more operable and faster to install compared to other methods using steel reinforcement plates. This achieves rapid alignment.

Detailed Implementation

[0015] This invention provides a steel connector for a concrete wall panel that allows for rapid alignment, such as... Figure 1-7 As shown, the cast-in-place connection area is located between two walls 18. It includes a rope assembly 16 and two anchor assemblies 2. The two anchor assemblies 2 are prefabricated in the two walls 18 respectively, and the rope assembly 16 is linked to the two anchor assemblies 2. Each anchor assembly 2 includes an anchor 1, a connecting cylinder 8, an outer sleeve 4, and a long bolt 6. The anchor 1 is located within the wall 18, and both the outer sleeve 4 and the connecting cylinder 8 are connected to the anchor 1. The outer sleeve 4 and the connecting cylinder 8 are interconnected, and the outer sleeve 4 and the connecting cylinder 8 are respectively provided with internal threads 3 and 7. The long bolt 6 is threaded to internal thread 3, and the long bolt 6 is adapted to the opening of the connecting cylinder 8. The long bolt 6 is linked to the rope assembly 16.

[0016] The anchor assembly 2 also includes a short bolt 13, a connecting pivot 14, and a nut 5. The short bolt 13 is threaded into an internal thread 7, and a hole 17 is provided through the short bolt 13 along its length. The connecting pivot 14 is pivotally connected to the end of the short bolt 13 away from the nut. The nut 5 is threaded into a long bolt 6.

[0017] The rope assembly 16 includes a main rope member 11 and two auxiliary rope members 9. The main rope member 11 and the two auxiliary rope members 9 pass through the opening 17 and are connected to the connecting pivot 14. The two auxiliary rope members 9 are symmetrical about the main rope member 11.

[0018] The rope assembly 16 also includes two main loops 15 and two auxiliary loops 10. The two main loops 15 are located on the main body of the main rope member 11 between the two walls 18, and the two auxiliary loops 10 are respectively located on the two auxiliary rope members 9.

[0019] The rope assembly 16 also includes a support 12 for branching the rope. The main rope member 11 and the two auxiliary rope members 9 pass through the support 12 and extend to the outside of the wall 18.

[0020] Working principle: In use, multiple anchor components 2 are first pre-embedded at equal intervals on the side of the wall 18. Then, by using a screwdriver to pass through the connecting cylinder 8 and rotate the long bolt 6 located inside the outer sleeve 4, the long bolt 6 blocks the opening of the connecting cylinder 8. Figure 3 As shown, by using the 5=6 inside to seal the opening of the connecting cylinder 8, it can effectively prevent sand and gravel from accidentally entering and causing blockage.

[0021] Meanwhile, the additional long bolts 6 not only serve as plugs, but also, when the wall 18 is transported to the designated location and the splicing of the two walls 18 begins, the long bolts 6 are first pulled out of the nuts 5. Then, personnel screw the openings 17 at both ends of the rope assembly 16 into the connecting cylinder 8, ensuring the rope assembly 16 is taut, thus completing the lateral connection of the two walls 18. Next, the disassembled long bolts 6 are interlaced and passed through the secondary loops 10 and main rope components 11 in the rope assemblies 16 at different levels, thereby connecting the rope assemblies 16 at different levels. Figure 5 As shown, rope assemblies 16 on different levels can be threaded together using nuts 5 and long bolts 6, thus forming a rectangular column frame structure. After the two connection templates are installed, concrete is poured. The frame structure of this invention provides support and constraint for the concrete, greatly improving the efficiency of concrete forming at the joints.

[0022] In summary, this quick-alignment concrete wall panel steel structure connector utilizes a combination of rope assembly 16, anchor bolt 1, connecting cylinder 8, outer sleeve 4, and long bolt 6. Because this invention uses rope assembly 16 for connection, it offers greater operability and faster installation compared to other methods using steel bars or plates, thus achieving rapid alignment.
