Description

Technical Field

[0001] This utility model belongs to the field of building structure technology, specifically relating to a non-welded self-adjusting fixing device for beams and columns. Background Technology

[0002] A beam-column joint in a frame structure refers to the connection point where a beam and a column intersect. In a building's frame, beams bear and transmit vertical and horizontal loads, while columns primarily bear and transmit vertical loads. As the point of intersection, the beam-column joint must reliably transmit these loads and ensure the stability and safety of the entire structure. Therefore, beam-column joints are typically designed as strong nodes, meaning their load-bearing capacity and stiffness are higher than surrounding members. Beam-column joints are responsible for transmitting and distributing internal forces, ensuring the structural integrity. Failure of a beam-column joint can cause the entire building to collapse; therefore, the joint is a weak point in a frame structure. While non-welded beam-column fixing devices are used to secure these joints, existing non-welded beam-column fixing devices have the following problems in use:

[0003] 1. Fixing the column and beam together by using diagonal support rods. This method of fixing the column and beam together by diagonal support cannot achieve local micro-adjustment during the fixing process, so precise positioning is required during fixing. If they do not match, they cannot be installed, resulting in rework or waste.

[0004] Second, the columns and beams are connected by brackets and bolts. The accuracy required during the connection is high. Even a slight deviation in the operation can cause gaps to appear between the columns and beams after the connection, affecting the stability and firmness of the beams and columns during subsequent use and hiding potential safety hazards. Utility Model Content

[0005] To address the problems mentioned in the background section, the purpose of this utility model is to provide a non-welded self-adjusting fixing device for beams and columns.

[0006] This utility model discloses a non-welded self-adjusting fixing device for beams and columns, comprising a column, a beam, a collar, an adjustable plug-in outer frame, and a plug-in right-angle fixing frame. The collar is sleeved on the upper side of the column, and adjustable plug-in outer frames are installed on both the left and right side walls of the collar. The plug-in right-angle fixing frame is inserted into the adjustable plug-in outer frame. The beam is placed on the upper end face of the collar, and the upper end of the plug-in right-angle fixing frame is connected to the bottom of the beam.

[0007] Preferably, the collar body has a connecting groove in the middle and a beam limiting groove on the upper end face. The beam limiting groove is connected to the connecting groove, and the width of the beam limiting groove is smaller than the width of the connecting groove, so that the upper end of the collar body forms a support part.

[0008] Preferably, the front and rear sidewalls of the collar body are provided with several threaded holes, which are connected to the sleeve groove, and the collar locking bolt is installed in the threaded holes.

[0009] Preferably, the outer wall of the adjustable plug-in frame is provided with a recessed T-shaped plug-in groove. The T-shaped plug-in groove is open at the top and closed at the bottom. An adjusting threaded hole is provided at the bottom of the T-shaped plug-in groove, and an adjusting bolt is connected in the adjusting threaded hole.

[0010] Preferably, the head of the adjusting bolt is integrally connected to a regular polygonal column, and a through-hole groove is provided on the side wall of the regular polygonal column.

[0011] Preferably, the front and rear side walls of the vertical end of the plug-in right-angle fixing bracket are provided with recessed adjustment grooves.

[0012] Preferably, the left side wall of the vertical end of the plug-in right-angle fixing bracket is provided with several threaded holes, and the fixing bracket locking bolts are connected in the threaded holes.

[0013] Preferably, a circular hole is provided at the bottom center of the vertical end of the plug-in right-angle bracket, and a set screw threaded hole is provided on the left side wall of the vertical end of the plug-in right-angle bracket, with the set screw threaded hole communicating with the circular hole.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: By cooperating with the column, beam, collar, adjustable plug-in outer frame, and plug-in right-angle fixing frame, a standardized fixing process for the column and beam is achieved. This allows for local adjustments during beam-column fixing based on specific conditions and design requirements, reducing the probability of gaps between beams and columns. This ensures a stable and reliable connection between the beam, column, and fixing device, improving the stable support strength after fixing to meet relevant specifications. It also facilitates a standardized and uniform process for beam-column connections, reducing assembly discrepancies. Specific advantages include:

[0015] First, a collar is used to install the beam on the column, which enables the upper end of the column to be connected. At the same time, the collar can limit the position of the beam and improve its stability.

[0016] Second, the adjustment method of using an adjustable plug-in external frame and a plug-in right-angle fixing frame to fix the beam can improve the stability of the column and beam after fixing, and the gap is less likely to appear after fixing. Attached Figure Description

[0033] like Figures 1 to 8 As shown, this specific embodiment uses a collar to fix the beam to the upper end of the column, and also uses the collar to limit the position of the beam. The specific technical solution is as follows: it includes a column 1, a beam 2, and a collar 3; the collar 3 is sleeved on the upper side of the column 1, and the beam 2 is placed on the upper end face of the collar 3. The collar 3 can be sleeved and fixed to the upper end of the column 1, as shown. Figure 2 , Figure 3 As shown, the collar body 3 has a connecting groove 3-1 in the middle, which can be fitted onto the column 1. The upper end face of the collar body 3 has a beam limiting groove 3-2, which can limit the beam 2. The beam limiting groove 3-2 is connected to the connecting groove 3-1. The width of the beam limiting groove 3-2 is smaller than the width of the connecting groove 3-1, so that the upper end of the collar body 3 forms a support part 3-5. The support part 3-5 can support the upper end face of the column 1, which can improve the stability after fixing. Several connecting threaded holes 3-3 are opened on the front and rear side walls of the collar body 3. The connecting threaded holes 3-3 are connected to the connecting groove 3-1. The collar locking bolt 3-4 is installed in the connecting threaded hole 3-3, and the connecting locking bolt 3-4 can fix the collar body 3 to the column 1.

[0034] like Figure 1As shown, in this specific embodiment, a plug-in right-angle fixing bracket is inserted into an adjustable plug-in outer frame. The adjustable plug-in outer frame allows for adjustment of the support height of the plug-in right-angle fixing bracket, facilitating adjustable fixing. The specific technical solution is as follows: It includes an adjustable plug-in outer frame 4 and a plug-in right-angle fixing bracket 5. Adjustable plug-in outer frames 4 are installed on both the left and right side walls of the collar body 3. The collar body 3 and the adjustable plug-in outer frame 4 are integrally connected or connected by bolts. The plug-in right-angle fixing bracket 5 is inserted into the adjustable plug-in outer frame 4. The plug-in right-angle fixing bracket 5 can move within the adjustable plug-in outer frame 4, facilitating adjustment of the fixing height. The upper end of the plug-in right-angle fixing bracket 5 is connected to the bottom of the beam body 2.

[0035] like Figure 4 , Figure 5 , Figure 6 As shown, in this specific embodiment, the plug-in right-angle bracket is plugged in using an adjustable plug-in outer frame, which also allows for adjustment of the support height of the plug-in right-angle bracket. The specific structure is as follows: a recessed T-shaped plug-in groove 4-1 is provided on the outer wall of the adjustable plug-in outer frame 4. The T-shaped plug-in groove 4-1 allows for the plug-in right-angle bracket 5 to be plugged in. The T-shaped plug-in groove 4-1 is open at the top and closed at the bottom. An adjusting threaded hole 4-2 is provided at the bottom of the T-shaped plug-in groove 4-1. An adjusting bolt 4-3 is connected to the adjusting threaded hole 4-2, and the head of the adjusting bolt 4-3 contacts the bottom of the plug-in right-angle bracket 5, facilitating the adjustment of the support height of the plug-in right-angle bracket 5. Figure 6 As shown, the head of the adjusting bolt 4-3 is integrally connected to a regular polygonal column 4-31. A through-hole groove 4-32 is provided on the side wall of the regular polygonal column 4-31. The regular polygonal column 4-31 can be supported on the bottom of the plug-in right-angle fixing bracket 5. The through-hole groove 4-32 can realize the fixing of the set screw.

[0036] like Figure 7 , Figure 8As shown, the front and rear side walls of the vertical end of the plug-in right-angle fixing bracket 5 are provided with recessed adjustment grooves 5-1. The adjustment grooves 5-1 and the front and rear side walls of the vertical end form a T-shaped plug. The T-shaped plug is inserted into the T-shaped plug groove 4-1, allowing the plug-in right-angle fixing bracket 5 to move within the T-shaped plug groove 4-1. Several threaded holes are provided on the left side wall of the vertical end of the plug-in right-angle fixing bracket 5. Fixing bracket locking bolts 5-2 are connected to the threaded holes, allowing the plug-in right-angle fixing bracket 5 to be fixed on the adjustable plug-in outer frame 4. The plug-in right-angle fixing bracket 5 has a circular hole 5-4 at the bottom center of its vertical end, and a set screw threaded hole 5-3 is provided on the left side wall of its vertical end. The set screw threaded hole 5-3 is connected to the circular hole 5-4. The regular polygonal prism 4-31 of the adjusting bolt 4-3 is placed in the circular hole 5-4. After adjustment, it is installed in the set screw threaded hole 5-3 through the set screw. At the same time, the head of the set screw will contact the through hole groove 4-32 of the regular polygonal prism 4-31, so that the regular polygonal prism 4-31 is connected to the plug-in right-angle fixing bracket 5.

[0037] The working principle of this specific embodiment is as follows: In use, the collar 3 is sleeved on the upper end of the column 1, so that the support part 3-5 is supported on the upper end surface of the column 1. At this time, the collar 3 is fixed by the collar locking bolt 3-4. Then, the plug-in right-angle fixing bracket 5 is inserted into the T-shaped plug-in slot 4-1 of the adjustable plug-in outer frame 4. At this time, the adjusting bolt 4-3 of the adjustable plug-in outer frame 4 is lowered so that the upper end surface of the straight end of the plug-in right-angle fixing bracket 5 is lower than the beam limiting groove 3-2 of the collar 3. Then, the beam 2 is placed in the beam limiting groove 3-2 of the collar 3. At this time, by rotating the adjusting bolt 4-3, the adjusting bolt 4-4 is lowered. The head of the -3 will push the plug-in right-angle fixing bracket 5 upward. The plug-in right-angle fixing bracket 5 moves upward in the T-shaped plug-in groove 4-1, so that the straight end of the plug-in right-angle fixing bracket 5 contacts the bottom of the beam 2 and is fixed to the beam 2 by bolts. At this time, the plug-in right-angle fixing bracket 5 is locked to the adjustable plug-in outer frame 4 by the fixing bracket locking bolt 5-2. At this time, the set screw is installed in the set screw thread hole 5-3, and the head of the set screw is placed in the through hole groove 4-32, so that the regular polygonal column 4-31 is connected to the plug-in right-angle fixing bracket 5. After the fixing is completed, the overall strength and stability are high, and gaps are not easy to occur. At the same time, it is convenient to adjust during fixing.
