Description

Technical Field

[0001] The utility model belongs to the technical field of building beams and columns, and in particular relates to a prestressed post-tensioned factory building beam-column connection structure. Background Art

[0002] Factory building beams and columns are essential components of factory buildings. They not only bear the weight of the superstructure but also resist various external forces. Selecting the right beams and columns is crucial to the safety and stability of the factory building. In steel-structured factories, the main structure typically consists of beams and columns made of welded or hot-rolled H-section steel. These beams and columns are assembled on-site as load-bearing structures. Prestressed and post-tensioned factory building beam-column connections are a common structural form used in industrial buildings to improve the building's load-bearing capacity and deformation resistance. This structure uses post-tensioning technology to prestress the beam-column connections for greater stability and durability. Unlike pre-tensioning, post-tensioning is performed after the concrete reaches a certain strength. Therefore, this method is suitable for large-span, heavy-load structures and effectively controls cracks and deformation.

[0003] For example, the Chinese utility model patent with the announcement number CN221372476U discloses a steel structure beam-column connection structure. This device can realize the positioning operation of box columns and box beams through the coordinated design of various structures and relying on the inherent structure of the steel structure parts; combined with the bolt connection method between the steel structure parts, it solves the previous problems of difficult docking and positioning and large welding workload when connecting box columns and box beams, thereby improving construction efficiency.

[0004] However, when the device is actually used, it is difficult to ensure that the screw holes are aligned when the box beam is spliced ​​with the box column, which makes installation inconvenient and requires adjustment, which reduces the connection efficiency of the steel structure.

[0005] In summary, there is a need for a prestressed post-tensioned factory building beam-column connection structure that can horizontally position box beams. Utility Model Content

By placing the crossbeam on an inverted L-shaped bracket, the device ensures that the mounting holes on the crossbeam can be accurately aligned with the mounting holes on the longitudinal beam, thereby improving the connection efficiency of the steel structure.

[0007] The technical solution adopted by the utility model to solve the above problems is: a prestressed post-tensioned factory building beam-column connection structure, comprising:

[0008] A longitudinal beam, wherein both sides of the longitudinal beam are fixedly connected to an inverted L-shaped bracket, a cross beam is provided on the inverted L-shaped bracket, and one side of the inverted L-shaped bracket is fixedly connected to a limit plate;

[0010] A further preferred technical solution is that: a clamping plate is provided on one side of the limit plate, a screw rod is rotatably connected to the clamping plate, and the screw rod and the limit plate are threadedly connected.

[0013] A further preferred technical solution is that a rectangular groove is provided on one side of the horizontal section of the inverted L-shaped bracket.

[0014] A further preferred technical solution is that: a plurality of guide members are fixedly connected to the inverted L-shaped bracket, and the guide members are slidably connected to the first vertical rod, the horizontal rod and the second vertical rod.

[0015] A further preferred technical solution is that anti-slip pads are provided on the bottom of the pressing plate and the top of the receiving plate.

[0016] A further preferred technical solution is that two inverted L-shaped brackets are provided, one on each side of the longitudinal beam.

[0017] A further preferred technical solution is that: a connecting plate is fixedly connected to the crossbeam, a mounting hole is provided on the connecting plate, and the crossbeam and the longitudinal beam are fixedly connected by fixing bolts.

[0031] Longitudinal beam 1, with inverted L-shaped brackets 2 fixedly connected on both sides of longitudinal beam 1, and crossbeam 3 set on inverted L-shaped bracket 2. Limit plates 4 are symmetrically fixedly connected to one side of inverted L-shaped bracket 2. Diagonal braces 5 are bolted to inverted L-shaped bracket 2 to increase the structural strength of inverted L-shaped bracket 2. A rectangular groove is opened on one side of the horizontal section of inverted L-shaped bracket 2. The horizontal distance between the two sets of limit plates 4 on the same side is consistent with the width of crossbeam 3. Connecting plates 6 are fixedly connected on both sides of one end of crossbeam 3. Connecting plates 6 are symmetrically opened with mounting holes. Crossbeam 3 and longitudinal beam 1 are fixedly connected by fixing bolts, which facilitates the connection and fixation between crossbeam 3 and longitudinal beam 1.

[0032] Auxiliary reinforcement components, the auxiliary reinforcement components include a pressure plate 101 arranged above the crossbeam 3, the other side of the inverted L-shaped bracket 2 is symmetrically fixedly connected with a screw 102 and the screw 102 passes through the pressure plate 101, both sides of the pressure plate 101 are symmetrically fixedly connected with a first vertical rod 103, both sides of the bottom of the inverted L-shaped bracket 2 are symmetrically connected with a cross bar 104, one end of the cross bar 104 is symmetrically hinged with the first vertical rod 103 on the same side through a hinge, and the inverted L-shaped bracket 2 is also symmetrically connected with four groups of second vertical rods 106, the second vertical rod 106 is connected to the other end of the cross bar 104 on the same side A second connecting rod 107 is symmetrically hinged between the two rods through a hinge, the top of the second vertical rod 106 is fixedly connected to a receiving plate 108, the external thread of the screw rod 102 is connected to a clamping nut 109 and the clamping nut 109 is in contact with the surface of the pressure plate 101, and the positions corresponding to the first vertical rod 103, the cross rod 104 and the second vertical rod 106 on the inverted L-shaped bracket 2 are fixedly connected with guide members, and the guide members are slidably connected to the first vertical rod 103, the cross rod 104 and the second vertical rod 106, which can play a certain guiding role in the movement of the first vertical rod 103, the second vertical rod 106 and the cross rod 104.

[0033] A splint 201 is provided on one side of the limit plate 4, and a screw rod 202 is rotatably connected to the splint 201 and the screw rod 202 is threadedly connected to the limit plate 4, and a guide rod 203 is symmetrically fixedly connected to the splint 201 and the guide rod 203 is slidingly connected to the limit plate 4. The outside of the splint 201 is evenly provided with anti-slip protrusions, which can play a certain guiding role in the horizontal movement of the splint 201.

[0034] The implementation principle of a prestressed post-tensioned factory building beam-column connection structure in the embodiment of the present application is as follows: first, the crossbeam 3 is placed on the inverted L-shaped bracket 2 and pushed toward the longitudinal beam 1. The symmetrically arranged limit plates 4 can prevent the crossbeam 3 from horizontally deviating, thereby ensuring that the mounting holes on the crossbeam 3 can be accurately aligned with the mounting holes on the longitudinal beam 1, thereby improving the connection efficiency of the steel structure. Then, the screw rod 202 is rotated to drive the clamping plate 201 to approach the crossbeam 3 and contact it. The clamping plate 201 can clamp and fix the crossbeam 3, which not only facilitates the connection between the crossbeam 3 and the longitudinal beam 1, but also improves the stability of the fixation of the crossbeam 3. Subsequently, the crossbeam 3 is connected to the longitudinal beam 1 using fixing bolts, and finally the pressure plate 101 is moved downward. By moving the pressure plate 101 vertically downward so that it contacts the surface of the beam 3, and using the clamping nut 109 to limit the pressure plate 101, the beam 3 can be clamped. At the same time, the vertical downward movement of the pressure plate 101 will also drive the first vertical rod 103 to move downward together. The first vertical rod 103 and the hinged effect between the cross bar 104 and the first connecting rod 105 can push the cross bar 104 to move inward. The hinged effect between the cross bar 104 and the second vertical rod 106 and the second connecting rod 107 can push the second vertical rod 106 vertically upward, so that the receiving plate 108 can contact the bottom of the beam 3 to achieve the auxiliary support function, further improving the stability of the beam 3 after connection.

[0035] A further improvement is that anti-slip pads are provided on the bottom of the pressure plate 101 and the top of the receiving plate 108 , which can increase the friction between the device and the beam 3 to improve the stability of the clamping and fixing of the beam 3 .
