Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to a beam-column joint connection device for prefabricated buildings. Background Technology

[0002] The field of prefabricated building technology involves standardized and modular component design based on the functional, structural, and aesthetic requirements of buildings. This ensures the versatility and adaptability of the components, and utilizes professional transportation tools and reasonable transportation plans to ensure that the components are safely and undamagedly transported to the construction site.

[0003] At present, the connection device is a key component or system used to achieve a reliable connection between precast beams and precast columns. It solves the problem of rapid and accurate assembly of precast components on the construction site. Through reasonable structural design and mechanical performance optimization, it ensures that various loads can be effectively transferred between beams and columns, including vertical gravity loads, horizontal wind loads and seismic forces.

[0004] However, the applicant believes the shortcomings are: 1. It is inconvenient to adjust the position according to subsequent needs, which reduces the practicality of the equipment to some extent; 2. The installation is cumbersome and the process is lengthy; 3. When the equipment is subjected to external impact, it may cause the entire equipment to shake or even collapse, which reduces the safety of the equipment to some extent.

[0005] To address this issue, we propose a prefabricated prefabricated building beam-column joint connection device. Utility Model Content

[0006] The purpose of this utility model is to provide a prefabricated assembly building beam-column joint connection device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated assembled building beam-column joint connection device, comprising a first prefabricated column,

[0008] The surface of the first precast column is slidably fitted with a first sleeve plate and a second sleeve plate. Fixing blocks are fixed at the top and bottom positions on both sides of one end of the second sleeve plate, and bolts are slidably inserted inside the fixing blocks. Friction plates are fixed at one end of the surface of the first sleeve plate and the second sleeve plate, and friction covers are slidably fitted on the surface of the friction plates. Anti-slip pads are fixed inside the friction plates and friction covers. Springs are fixed at corresponding positions on both ends of the two sets of anti-slip pads.

[0009] Preferably, square grooves are provided on both sides of one end of the second sleeve plate, and square blocks are fixed on both sides of one end of the first sleeve plate, with the surface of the square blocks fitting into the surface of the square grooves. Through the cooperation of the square grooves and square blocks, when the first sleeve plate and the second sleeve plate need to be fixed in position, they can be fixed in position.

[0010] Preferably, the surface of the bolt is threaded to the surface of the block, and the position of the first plate can be fixed by rotating the bolt.

[0011] Preferably, a limiting plate is provided at the middle position of the bolt, and a limiting groove is provided inside the fixing block, with the surface of the limiting groove fitting against the surface of the limiting plate. Through the cooperation of the limiting plate and the limiting groove, the movement position of the bolt can be restricted, thus preventing it from detaching from the inside of the fixing block.

[0012] Preferably, circular grooves are provided on the upper and lower positions of one side of the second sleeve plate, and the positions of the circular grooves correspond to the positions of the bolts. By using the circular grooves and bolts together, the positions of the first sleeve plate and the second sleeve plate can be fixed more quickly.

[0013] Preferably, the friction plate has grooves on both sides, and the inner walls of both sides of the friction cover are fixed with sliders, and the surface of the sliders is in contact with the surface of the grooves. By using the grooves and sliders together, the position of the friction cover can be restricted, and the stability of the friction cover can be improved.

[0014] Preferably, one end of the friction cover is fixedly connected to a node plate, and the bottom end of the node plate is threadedly connected to a fastener, and the fastener is threadedly connected to a second precast column. Through the cooperation of the node plate and the fastener, the position of the second precast column can be fixed, thereby improving the practicality of the equipment.

[0015] This utility model provides a prefabricated assembled building beam-column joint connection device, which has the following beneficial effects:

[0016] By moving the first and second sets of plates so that their inner wall surfaces are in contact with the surface of the first precast column, and at the same time, the square groove inside the second set of plates is in contact with the square surface of one end of the first set of plates, the positions of the first and second sets of plates are fixed. Then, the positions of the first and second sets of plates are fixed by rotating the bolts. Through the above operation, the first and second sets of plates can be disassembled and installed more easily, thereby avoiding the inconvenience of adjusting their positions and improving the practicality and convenience of the equipment to a certain extent.

[0017] By using springs, the impact of external forces on the first precast column can be reduced. At the same time, the anti-slip pads can protect the inner walls of the friction plate and friction cover, preventing the springs from falling off or being damaged after long-term use. This also improves the stability of the node plate and the second precast column during installation. Through the above operations, the safety of the equipment can be improved.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This embodiment proposes a prefabricated prefabricated building beam-column joint connection device.

[0026] Example 1

[0027] like Figures 1 to 3As shown in the figure, this embodiment proposes a prefabricated prefabricated building beam-column joint connection device, including a first prefabricated column 1. A first sleeve plate 2 and a second sleeve plate 3 are slidably fitted on the surface of the first prefabricated column 1. Fixing blocks 4 are fixed at the upper and lower positions on both sides of one end of the second sleeve plate 3, and bolts 5 are slidably inserted into the interior of the fixing blocks 4. Square grooves are opened in the interior of both sides of one end of the second sleeve plate 3. Square blocks are fixed at both sides of one end of the first sleeve plate 2, and the surface of the square blocks is in contact with the surface of the square grooves. The surface of the bolts 5 is threadedly connected to the surface of the square blocks. A limiting plate is provided at the middle position of the bolts 5. A limiting groove is opened in the interior of the fixing blocks 4, and the surface of the limiting groove is in contact with the surface of the limiting plate. Circular grooves are opened at the upper and lower positions on both sides of one end of the second sleeve plate 3, and the positions of the circular grooves correspond to the positions of the bolts 5.

[0028] In the above embodiment, the position of the node plate 12 can be determined by the cooperation of the first sleeve plate 2 and the second sleeve plate 3. When the inner wall surfaces of the first sleeve plate 2 and the second sleeve plate 3 are moved to fit against the surface of the first precast column 1, the position of the two is fixed by rotating the bolt 5. The position of the bolt 5 can be restricted by the cooperation of the fixing block 4, which can prevent it from falling or being lost when not in use, thus improving the practicality of the equipment to a certain extent. When the surfaces of the square groove and the block are fitted together, the position of the round groove corresponds to the position of the bolt 5. Then, the bolt 5 is rotated to fix the position of the block by passing through the interior of the second sleeve plate 3.

[0029] Example 2

[0030] like Figure 4 As shown, based on the same concept as the above embodiment, this embodiment also proposes: a friction plate 6 is fixed on one end surface of the first set plate 2 and the second set plate 3, and a friction cover 7 is slidably fitted on the surface of the friction plate 6. Anti-slip pads 10 are fixed inside the friction plate 6 and the friction cover 7. Springs 11 are fixed at corresponding positions on both ends of the two sets of anti-slip pads 10. Slide grooves 8 are opened on both sides of the friction plate 6. Slider 9 is fixed on both inner walls of the friction cover 7, and the surface of the slider 9 is in contact with the surface of the slide groove 8. A node plate 12 is fixedly connected to one end of the friction cover 7, and a fastener is threadedly connected to the bottom end of the node plate 12. The fastener is threadedly connected to the second precast column 13.

[0031] In the above embodiments, the position of the friction cover 7 can be restricted by the combined use of the slide groove 8 and the slider 9, and the stability of the friction cover 7 can be improved. The anti-slip pad 10 and the spring 11 can be used to buffer the impact force from the outside, thereby improving the safety of the equipment.

[0032] Working principle: When the equipment is in use, firstly move the first set plate 2 and the second set plate 3 so that their inner wall surfaces are in contact with the surface of the first precast column 1. At this time, the square groove is in contact with the surface of the block, thereby fixing the position of the first set plate 2 and the second set plate 3. Then rotate the bolt 5 to fix the position of the first set plate 2 and the second set plate 3. Next, move the second precast column 13 to the surface where the two sets of node plates 12 are in contact. Then fix the node plates 12 according to the fasteners.

[0033] When the equipment is in use, if it is subjected to an external impact, the anti-slip pad 10 and the spring 11 work together to buffer the impact force, thereby preventing damage to the first precast column 1. At the same time, the friction plate 6 and the friction cover 7 work together to make the second precast column 13 more stable during installation.

[0034] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.

Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0036] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
