Description

Technical Field

[0001] This invention relates to the field of steel structure installation technology, and in particular to a reinforcement clamp and construction method for decorative column pin connection nodes. Background Technology

[0002] Modern public buildings, such as museums and convention centers, increasingly utilize steel decorative columns on their facades to simultaneously meet structural and aesthetic requirements. The connection between these decorative columns and the main steel structure typically involves connecting lugs at both ends of the column, secured to these lugs via pins. During construction, the upper connecting lug of the decorative column is first aligned with the main steel structure's connecting lug, then the pin is inserted and tightened. The lower lug is then connected and secured using the same pin. However, during the adjustment of the lower lug alignment after the upper pin is tightened, shearing between the two lugs can cause the pin to disengage, potentially leading to the decorative column falling. This poses a significant safety hazard during construction. Summary of the Invention

[0003] The purpose of this invention is to address the safety hazards of decorative columns during construction by providing a method for reinforcing and strengthening the pin connection nodes of decorative columns.

[0004] The technical solution adopted by the present invention to solve the aforementioned problem is as follows: A reinforcing clamp for a decorative column pin connection node includes an outer reinforcing part and an inner reinforcing part, which are symmetrically arranged on the outer sides of the two ear plates of the pin connection node; the inner reinforcing part has a through hole in the middle, the through hole being greater than or equal to the diameter of the end plate of the pin; the inner reinforcing part is fixed to the back side of the outer reinforcing part; the outer reinforcing part also has bolt holes at both ends that penetrate the outer reinforcing part and the inner reinforcing part, the distance between the bolt holes at both ends being greater than the overlap width of the two ear plates, and reinforcing bolts are installed in the bolt holes.

[0005] Compared with the prior art, the present invention employing the above structure has the following advantages: This ensures safety and reliability during construction. Furthermore, after the decorative column is installed, this reinforcement device can serve as part of the overall structure, ensuring that the decorative column can reinforce and strengthen the pin when subjected to wind loads and vibrations. This greatly enhances the shear resistance of the pin, thereby ensuring structural safety and stability.

[0006] Preferably, the outer reinforcing part is a small section of channel steel with a length of 300mm and a diameter of [8], and the bolt holes on its surface are located 40mm from the end of the small section of channel steel and have a diameter of 18mm.

[0007] Preferably, the inner reinforcing part is a flat steel plate with a thickness of 10mm, a length of 290mm, and a width of 70mm, with a through hole diameter of 60mm and bolt holes at both ends 35mm from the end of the back plate.

[0008] To address the aforementioned problem, this invention also provides a construction method for reinforcing the pin-connection node of decorative columns, the specific solution of which is as follows: The construction method for reinforcing the joint using the aforementioned decorative column pin-connection joint reinforcement clamp is carried out according to the following steps: First, fabricate a pin reinforcement fixture: Step 1: Take a short section of channel steel with a length greater than or equal to the width of the root of the ear plate of the pin connection node and a steel plate as the back plate.

[0009] Step 2: Make a through hole in the middle of the back plate. The diameter of the through hole is equal to the diameter of the end plate of the pin. The through hole can fit on the outside of the pin. According to the overlap width of the ear plates of the pin connection node, make a bolt hole at each end of the back plate.

[0010] Step 3: Based on the overlap width of the ear plates of the pin connection node, drill a bolt hole at each end of the web plate.

[0011] Step 4: Align the back plate with the center of the small channel steel section, and also align the back plate with the bolt holes on the small channel steel section. Then, make single-sided fillet welds around the back plate to the back of the web of the small channel steel section, with a weld height of 6mm. Make two reinforcement clamps in total, and make two as a set.

[0012] Then, reinforce the installation: Step 5: After aligning the column ear plate with the main body ear plate, insert the pin and tighten it.

[0013] Step 6: Take two reinforcing clamps made in Step 4 and set them on the outer surfaces of the two plates respectively, with their through holes fitted onto the surface of the sealing plate.

[0014] Step 7: Take two reinforcing bolts, pass them through the bolt holes at both ends of the reinforcing fixture, and tighten the double nuts on the reinforcing bolts left and right. Roughen the threads at the ends of the reinforcing bolts.

[0015] Compared with the prior art, the present invention employing the above method has the following advantages: This invention, when installing decorative columns with pins as connecting nodes, utilizes a pre-drilled hole in the center of a clamp made of channel steel and a back plate. The two ends of the pin are fitted into the pre-drilled hole, and the clamps are secured together by galvanized bolts on both sides. This construction method improves the safety and stability of the installation process, solving the safety problems such as component falling during installation caused by the lack of reinforcement measures after installing the upper pin of the decorative column and connecting the upper end to the lower end as the axis in traditional construction methods. It also saves labor costs caused by repeated tightening due to insecure pin fastening, and reduces the difficulty and risk of high-altitude construction.

[0016] Preferably, the reinforcing bolts are 4.8 grade M16·100 galvanized bolts. Attached Figure Description

The diameter of the through hole 7 is equal to the diameter of the end plate of the pin shaft. The through hole 7 can be fitted onto the outside of the pin shaft. According to the overlap width of the ear plates of the pin shaft connection node, make two bolt holes 8 with a diameter of 18mm at both ends of the back plate 6.

[0022] Then, reinforce the installation: Step 5: After aligning the column ear plate 2 with the main body ear plate 4, insert the pin and tighten it.

[0023] Step 6: Take two reinforcing clamps made in Step 4 and set them on the outer surfaces of the two plates respectively, with their through holes 7 fitted onto the surface of the sealing plate.

[0024] Step 6: Take two 4.8 grade M16·100 reinforcing bolts 9, pass them through the bolt holes 8 at both ends of the reinforcing fixture, and tighten the double nuts on the reinforcing bolts 9 left and right. Roughen the threads at the ends of the reinforcing bolts 9.
