Description

Technical Field

[0001] This utility model relates to the field of building connector technology, and specifically to a fastener for connecting steel structures in buildings. Background Technology

[0002] In the field of steel structure construction, the performance of connecting fasteners directly affects the stability and safety of building structures. With the booming development of the construction industry and the emergence of various new types of buildings, higher requirements are placed on the reliability and convenience of steel structure connections.

[0003] According to the public announcement (CN206902924U), a steel structure corner connection structure is disclosed. This technology discloses that it "includes a corner connection structure body, which includes a first target steel body, a second target steel body, and a connecting steel body. The first target steel body is fixedly connected to the second target steel body through the connecting steel body. In use, the connecting post on the connecting steel body is inserted into the connecting hole on the first target steel body, and then bolts are passed through the first bolt hole and the second bolt hole in sequence to fix the connection. After fixing, the connecting hole on the second target steel body is installed into the connecting post on the connecting steel body, and then bolts are used to fix the connection. The design of the connecting post can strengthen the connection strength of the steel structure and increase the stability of the building. This invention has a simple structure, is easy to operate, saves time and effort, and is relatively safe, without causing indirect harm to the human body."

[0004] However, in the aforementioned comparative documents, during actual use of buildings, they will face various complex environmental factors and external forces, such as wind, seismic forces, and the vibration of the building itself. Under the continuous influence of these external forces, it may be inconvenient to reinforce the connection at the corner of the square pipe, thereby reducing the load-bearing capacity of the steel structure, shortening the service life of the building, and even potentially causing serious safety accidents.

[0005] To address the aforementioned issues, this application proposes a fastener for connecting steel structures in buildings. Utility Model Content

[0008] The stabilizing component includes a positioning plate with a second long bolt threaded through it. A pressure plate is rotatably connected to the end of the second long bolt away from the nut. A first threaded hole is provided on the pressure plate.

[0009] The clamping assembly includes a first long bolt threaded through the clamping plate, with a clamping plate rotatably connected to the end of the first long bolt away from the nut, and the positioning plate is fixedly connected to the clamping plate. By setting the first long bolt and the clamping plate, the clamping and limiting of the square steel pipe is achieved.

[0010] A second gasket is fixedly connected to the bottom of the pressure plate. The second gasket has a second threaded hole, and the second gasket is adapted to the second threaded hole. By setting the second gasket and the second threaded hole, the stability of the pressure plate on the square steel pipe is increased.

[0011] A stabilizing rod is slidably connected to the positioning plate, and the stabilizing rod is fixedly connected to the pressure plate. By setting the stabilizing rod, the stability of the pressure plate moving up and down is increased.

[0012] A first shim is fixed on the clamping plate, which enables the clamping plate to stably clamp the square steel pipe.

[0013] The support assembly includes a diagonal brace plate, a limit plate is detachably connected to the clamping plate, the limit plate is fixedly connected to the diagonal brace plate, and a short bolt is threadedly connected to the limit plate. The short bolt is threadedly connected to the clamping plate. By setting the diagonal brace plate, the limit plate, and the short bolt, the stability of the clamping plate is increased.

[0014] The beneficial effects of this utility model are:

[0015] The clamping plate facilitates the splicing of two square pipes. The clamping components initially clamp and limit the square steel pipes, and adjust the position of the stabilizing components. The second long bolt and pressure plate work together to further limit the spliced ​​square pipes, thus facilitating the connection of the two square pipes and further increasing the stability of the connection at the corner of the two square pipes.

[0016] The limiting plate is detachably installed on the clamping plate by means of short bolts, and the stability of the clamping plate is increased by means of diagonal bracing plates, thereby increasing the stability of the clamping plate in fastening the square steel pipe.

[0029] Reference Figure 1-3 A fastener for connecting steel structures in a building includes a clamping plate 1, a clamping assembly 3 for clamping steel components, and a stabilizing assembly 4 for further positioning the steel components. The clamping assembly 3 is disposed on the clamping plate 1, and there are four sets of clamping assemblies 3 evenly distributed on the clamping plate 1. The stabilizing assembly 4 is disposed on the clamping assembly 3, and the number of clamping assemblies 3 and stabilizing assemblies 4 is equal and corresponds one-to-one. The clamping plate 1 is provided with a support assembly 2, which increases the stability of the clamping plate 1 in fastening square pipes. There are two sets of support assemblies 2, which are symmetrically distributed around the central axis of the clamping plate 1. The longitudinal section of the clamping plate 1 is L-shaped.

[0030] The stabilizing component 4 includes a positioning plate 41, which is L-shaped. A second long bolt 42 is threaded through the positioning plate 41. The end of the second long bolt 42 away from the nut is rotatably connected to a pressure plate 43. The second long bolt 42 is located on one side of the pressure plate 43 near the edge. The pressure plate 43 has a first threaded hole 44. During the docking of the two square steel pipes, the clamping plate 1 moves to fit against the square steel pipe. The clamping component 3 clamps and limits the square steel pipe to prevent it from shifting during the tightening process. The second long bolt 42 rotates and moves closer to the square steel pipe. The pressure plate 43 moves to fit against the square steel pipe. The threaded pin moves through the first threaded hole 44 to fit against the square steel pipe, thereby stabilizing the square steel pipe.

[0031] Reference Figure 1 and Figure 3 The clamping assembly 3 includes a first long bolt 31 threaded through the clamping plate 1. The end of the first long bolt 31 away from the nut is rotatably connected to the clamping plate 32. The first long bolt 31 is located at the center of one side of the clamping plate 32. The positioning plate 41 is fixedly connected to the clamping plate 32. The first long bolt 31 rotates and moves towards the square pipe. The clamping plate 32 moves smoothly to fit against the square steel pipe, thereby clamping and limiting the square steel pipe.

[0032] Reference Figure 1 and Figure 3 The bottom of the pressure plate 43 is fixedly connected to a second gasket 45. The second gasket 45 is mainly made of rubber and has a certain elasticity. A second threaded hole 46 is opened on the second gasket 45. The second gasket 45 is adapted to the second threaded hole 46. The threaded nail passes through the first threaded hole 44 and the second threaded hole 46 and is connected to the square steel pipe. The second gasket 45 increases the stability of the pressure plate 43 on the square steel pipe.

[0033] Reference Figure 1 and Figure 3A stabilizing rod 47 is slidably connected to the positioning plate 41. The stabilizing rod 47 is located between the pressure plate 43 and the positioning plate 41. The stabilizing rod 47 is fixedly connected to the pressure plate 43, and the stabilizing rod 47 increases the stability of the pressure plate 43 moving up and down.

[0034] Reference Figure 1 and Figure 3 A first gasket 33 is fixed on the clamping plate 32. The first gasket 33 is mainly made of rubber and has a certain elasticity. Part of the first gasket 33 is installed on the positioning plate 41. The first gasket 33 increases the clamping effect of the clamping plate 32 on the square steel pipe.

[0035] Reference Figure 1 and Figure 4 The support component 2 includes a diagonal brace 21, which is inclined. A limiting plate 22 is detachably connected to the clamping plate 1. The limiting plate 22 is fixedly connected to the diagonal brace 21. A short bolt 23 is threaded onto the limiting plate 22 and threaded onto the clamping plate 1. The short bolt 23 allows the limiting plate 22 to be detachably installed on the clamping plate 1. The diagonal brace 21 and the limiting plate 22 increase the stability of the clamping plate 1 in fastening the square steel pipe.

[0036] Working principle:

[0037] The fasteners for connecting the steel structure of this building first move the clamping plate 1 onto a square steel pipe, and then move another steel pipe to fit against the clamping plate 1. The two square steel pipes are spliced ​​in an L-shape. The first long bolt 31 rotates and moves towards the square steel pipe, and the clamping plate 32 drives the first washer 33 to move to fit tightly against the square steel pipe. The first washer 33 is compressed and deformed, thereby clamping and limiting the square steel pipe. Subsequently, the second long bolt 42 rotates and moves towards the square steel pipe, and the pressure plate 43 drives the second washer 45 to fit tightly against the square steel pipe, thereby further stabilizing the square steel pipe. A threaded nail that matches the first threaded hole 44 is selected. The threaded nail is threadedly connected to the square steel pipe through the first threaded hole 44, the second threaded hole 46, and the first threaded hole 46, thereby positioning the square steel pipe. The limiting plate 22 moves to fit against the clamping plate 1, and the short bolt 23 is threaded through the limiting plate 22 and then connected to the clamping plate 1, thereby further increasing the stability of the connection between the two square steel pipes after splicing by the clamping plate 1.
