Description

Technical Field

[0001] This utility model relates to the field of building wall panel construction technology, and in particular to a steel structure connection device for building wall panels. Background Technology

[0002] Currently, most construction projects involve concrete structures. Among these, formwork installation, rebar tying, and concrete pouring are the most fundamental components, and their quality directly determines the overall quality and structural safety of the project. Formwork installation, in turn, directly impacts the rebar and concrete work, making it a critical step in concrete structure engineering. Cast-in-place formwork construction is currently the mainstream construction method in cast-in-place construction.

[0003] For example, patent application number CN201822088246.5 discloses a device for preventing bulging of wooden formwork on beam sides, including a fixed rod, a support rod, a tie rod, a support plate fastener, a connecting fastener, and a ring fastener. The fixed rod is characterized by having two ring fasteners fitted on it, and connecting fasteners fitted at both ends; one end of the support rod is connected to the connecting fastener, and the other end is connected to the support plate fastener; the tie rod partially surrounds and tightly fastens the support rod and is connected to the ring fastener. This device can effectively solve the problem of bulging and can be reused, resulting in good economic benefits. The support rod rests against the left and right sides of the formwork, but because the support plate fasteners on the support rod provide single-point support, the formwork surface experiences uneven stress during pouring, leading to localized warping and affecting the pouring of the wall panel. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a steel structure connection device for building wall panels, which solves the shortcomings of existing devices.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a steel structure connection device for building wall panels, including a tie rod and connecting rods provided at the left and right ends of the tie rod, a first joint is provided at the end of the tie rod facing the connecting rod, a second joint is provided at the end of the connecting rod facing the tie rod, the first joint and the second joint are inserted into each other, and a locking structure is provided at the insertion point of the first joint and the second joint.

[0006] The connecting rod has at least two support rods at the end away from the tie rod. One end of the support rod is hinged to the connecting rod, and the other end of the support rod is provided with an anti-slip pad. The anti-slip pad is hinged to the support rod. A steel frame support structure is provided on the outside of the connecting rod to limit the position of the support rod.

[0007] A further improvement is that: a groove A is provided on one side of the first connector, and a groove B is provided on one side of the second connector. Grooves A and B are offset. The first connector engages with groove B, and the second connector engages with groove A.

[0008] A further improvement is that: the first connector is provided with a second cylindrical pin at the end away from the pull rod, the second cylindrical pin is fixedly connected to the first connector, and the second cylindrical pin engages with a second pin hole opened at the end of the connecting rod; the second connector is provided with a first cylindrical pin at the end away from the connecting rod, the first cylindrical pin is fixedly connected to the second connector, and the first cylindrical pin engages with a first pin hole opened at the end of the pull rod.

[0009] A further improvement is that the locking structure includes a prismatic pin and a V-groove. The V-groove is opened on the side where the second connector and the first connector are close to each other. The prismatic pin is placed in the diamond-shaped through hole formed by the two V-grooves. When the V-groove and the diamond-shaped through hole are slidably connected, the outer side of the first connector and the second connector is provided with an anti-detachment structure to prevent the prismatic pin from falling off.

[0010] A further improvement is that the anti-detachment structure includes a sleeve, which is sleeved on the outside of the connecting rod. The outside of the first connector is provided with a second external thread, and the outside of the second connector is provided with a first external thread. The sleeve is threadedly connected to the first external thread and the second external thread.

[0011] A further improvement is that the steel frame support structure includes a fixing ring and at least two V-shaped tie rods. The fixing ring is sleeved on the outside of the connecting rod, and the connecting rod is fixedly connected to the fixing ring. The V-shaped tie rods are fixedly set on the outside of the fixing ring, and the support rod passes through the V-shaped tie rods. The gap width of the V-shaped tie rod near the fixing ring is smaller than the gap width of the other end of the V-shaped tie rod.

[0012] A further improvement is that a screwing head is fitted on the outer side of the sleeve, and the screwing head is fixedly connected to the sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The connecting rod supports the side formwork through multiple support rods. When the formwork expands due to the pouring of concrete, the steel frame support structure will restrict the movement of the support rods and support the formwork from both sides to prevent bulging. The multi-point fixing method provides better stability.

[0015] The connecting rod is fixed to the left and right sides of the tie rod by plugging it in, which facilitates the disassembly and assembly of the connecting rod after pouring. The locking structure is used to fix the connecting rod, so that the connecting rod will not detach from the tie rod during concrete pouring, thus improving reliability. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a steel structure connection device for building wall panels, including a tie rod 1 and connecting rods 2 provided at the left and right ends of the tie rod 1. The end of the tie rod 1 facing the connecting rod 2 is provided with a first connector 9, and the end of the connecting rod 2 facing the tie rod 1 is provided with a second connector 10. The first connector 9 and the second connector 10 are inserted into each other, and a locking structure is provided at the insertion point of the first connector 9 and the second connector 10.

[0023] At least two support rods 6 are provided at the end of the connecting rod 2 away from the tie rod 1. One end of the support rod 6 is hinged to the connecting rod 2, and the other end of the support rod 6 is provided with an anti-slip pad 7. The anti-slip pad 7 is hinged to the support rod 6. A steel frame support structure is provided on the outside of the connecting rod 2 to limit the position of the support rod 6.

[0024] After laying the bottom formwork and side formwork of the beam, and reserving installation holes on the side formwork, insert tie rod 1 into them. After connecting rod 2 is connected to the left and right ends of tie rod 1, connecting rod 2 will support the side formwork through multiple support rods 6. When the formwork expands due to the pouring of concrete, the steel frame support structure will restrict the movement of support rods 6 and support the formwork from the left and right sides to prevent bulging. The multi-point fixing method provides better stability.

[0025] The connecting rod 2 is fixed to the left and right sides of the tie rod 1 by plugging it in, which makes it easy to disassemble and reassemble the connecting rod 2 after pouring. The locking structure is used to fix the connecting rod 2. The connecting rod 2 will not detach from the tie rod 1 during concrete pouring, which improves reliability.

[0026] It is worth explaining in detail that a groove A is provided on one side of the first connector 9, and a groove B is provided on one side of the second connector 10. Grooves A and B are offset. The first connector 9 engages with groove B, and the second connector 10 engages with groove A. When the pull rod 1 is connected to the connecting rod 2, the first connector 9 abuts against one side of the second connector 10 and engages with groove B, and the second connector 10 abuts against one side of the first connector 9 and engages with groove A.

[0027] More specifically, the first connector 9 has a second cylindrical pin 16 at the end away from the pull rod 1. The second cylindrical pin 16 is fixedly connected to the first connector 9 and engages with the second pin hole 17 at the end of the connecting rod 2. The second connector 10 has a first cylindrical pin 11 at the end away from the connecting rod 2. The first cylindrical pin 11 is fixedly connected to the second connector 10 and engages with the first pin hole 14 at the end of the pull rod 1.

[0028] When the first connector 9 and the second connector 10 are joined together, the first cylindrical pin 11 on the second connector 10 will be inserted into the first pin hole 14 at the end of the pull rod 1, and the second cylindrical pin 16 on the first connector 9 will be inserted into the second pin hole 17 at the end of the connecting rod 2. The first cylindrical pin 11, by engaging with the first pin hole 14, and the second cylindrical pin 16, by engaging with the second pin hole 17, limit the first connector 9 and the second connector 10, restricting their lateral movement.

[0029] Regarding the locking mechanism:

[0030] The locking structure includes a prismatic pin 8 and a V-groove 13. The V-groove 13 is opened on the side where the second connector 10 and the first connector 9 are close to each other. The prismatic pin 8 is placed in the diamond-shaped through hole formed by the two V-grooves 13. When the V-groove 13 is slidably connected to the diamond-shaped through hole, the outer side of the first connector 9 and the second connector 10 is provided with an anti-detachment structure to prevent the prismatic pin 8 from falling off.

[0031] After the first connector 9 and the second connector 10 are engaged, the two V-grooves 13 will also engage with each other, pushing the prismatic pin 8 into the two V-grooves 13. The prismatic pin 8 will limit the first connector 9 and the second connector 10 by cooperating with the two V-grooves 13, restricting the axial movement of the first connector 9 and the second connector 10. It will also work with the first cylindrical pin 11 and the second cylindrical pin 16 to complete the connection and locking of the first connector 9 and the second connector 10.

[0032] The anti-detachment structure is set on the outside of the first connector 9 and the second connector 10 to protect the prism pin 8. Specifically, the anti-detachment structure includes a screw sleeve 3, which is sleeved on the outside of the connecting rod 2. The first connector 9 has a second external thread 15 on its outside, and the second connector 10 has a first external thread 12 on its outside. The screw sleeve 3 is threadedly connected to the first external thread 12 and the second external thread 15.

[0033] After the first connector 9 and the second connector 10 are engaged, push the prismatic pin 8 into the V-groove 13. The prismatic pin 8 will lock the first connector 9 and the second connector 10. Rotate the outer sleeve 3 of the connecting rod 2 to simultaneously rotate the sleeve 3 to the outer side of the first connector 9 and the second connector 10. The sleeve 3 will seal the V-groove 13, ensuring that the prismatic pin 8 will not fall out of the V-groove 13.

[0034] Regarding the steel frame support structure:

[0035] The steel frame support structure includes a fixing ring 4 and at least two V-shaped tie rods 5. The fixing ring 4 is fitted around the outside of the connecting rod 2, and the connecting rod 2 is fixedly connected to the fixing ring 4. The V-shaped tie rods 5 are fixedly set outside the fixing ring 4, and the support rod 6 passes through the V-shaped tie rods 5. The gap width of the V-shaped tie rod 5 near the fixing ring 4 is smaller than the gap width of the other end of the V-shaped tie rod 5. The purpose of this design is that when the support rod 6 is supported on the left and right sides of the template, the template will expand and compress the support rod 6, pushing the support rod 6 towards the end of the V-shaped tie rod 5 away from the connecting rod 2, and moving along the inner gap of the V-shaped tie rod 5. As the gap of the V-shaped tie rod 5 continues to narrow, the support of the V-shaped tie rod 5 for the support rod 6 will become increasingly firm.

[0036] To facilitate the rotation of the sleeve 3, in a preferred embodiment, a screw head 18 is fitted on the outer side of the sleeve 3, and the screw head 18 is fixedly connected to the sleeve 3. The screw head 18 is located on the outer side of the sleeve 3, making it convenient for the user to hold the sleeve 3.

[0037] How this application works:

[0038] After laying the bottom formwork and side formwork of the beam, and reserving installation holes on the side formwork, insert tie rod 1 into them. Connecting rod 2 is then connected to the left and right ends of tie rod 1. Connecting rod 2 will support the side formwork through multiple support rods 6. When the formwork expands due to the pouring of concrete, the steel frame support structure will restrict the movement of the support rods 6 and support the formwork from the left and right sides to prevent bulging. Connecting rod 2 is fixed to the left and right sides of tie rod 1 by plugging. The locking structure is used to fix connecting rod 2 to ensure that connecting rod 2 will not detach from tie rod 1 during concrete pouring, thus improving reliability.
