Description

Technical Field

[0001] This application relates to the field of prefabricated building construction technology, and in particular to a docking auxiliary device for prefabricated steel structure beams and columns. Background Technology

[0002] Prefabricated steel structure buildings are structures where prefabricated steel components are assembled and fixed on-site using reliable connection methods, with steel structures serving as the main load-bearing components. This construction method is characterized by prefabrication, industrialization, and green construction, and represents an important direction for the construction industry's transformation towards high-quality development. When installing columns and beams, auxiliary connection devices are typically used to reduce the difficulty of the connection process.

[0003] Utility model patent CN220377891U discloses an auxiliary connection fixture for prefabricated steel structure beams and columns. The fixture is clamped and fixed to the column via a clamping part formed between the base frame and the connecting plate, positioned below the point where the beam and column need to be joined. This allows the beam's end to be placed on a positioning support platform and positioned via a positioning groove when the crane lifts it. However, this structure only supports the beam through the positioning support platform, limiting the installation height. The lack of horizontal restraint on the beam makes it prone to tilting, causing gaps at the joint between the beam and column. This affects the stability of the beam and column after welding, requiring re-lifting of the beam and increasing construction costs. Summary of the Invention

[0004] The present invention aims to solve the problem of the lack of horizontal positioning of the crossbeam in the above-mentioned auxiliary device, thereby providing an auxiliary device that can stably connect the crossbeam and the column.

[0005] The technical solution adopted by this utility model to solve the aforementioned problem is:

[0006] An auxiliary device for connecting prefabricated steel structure beams and columns is used for auxiliary positioning when beams and columns are installed together. It includes a first clamping component and a second clamping component. The first clamping component is used to clamp the column. A base is connected to one side of the first clamping component. A horizontally movable support frame is provided on the base. The second clamping component is vertically movable and is used to clamp the beam.

[0007] Compared with the prior art, the advantages of this utility model, which adopts the above technical solution, are as follows:

[0008] The auxiliary device of this utility model can stably connect the column and the crossbeam. The first clamping component clamps the column, fixing the device on the column. The second clamping component clamps the crossbeam, making the crossbeam perpendicular to the column. The second clamping component can move vertically on the support frame, which facilitates the vertical movement of the crossbeam and adjusts the installation position of the crossbeam and the column. The support frame can move horizontally on the base, which facilitates the horizontal movement of the crossbeam and the column, allowing the crossbeam to abut against the column and making it easy to weld and fix the abutment position of the crossbeam and the column.

[0009] As a preferred embodiment, a further technical solution of this utility model is:

[0010] The first clamping assembly includes two geometric brackets, which are looped around the column and securely connected to each other. This structure facilitates the fixing of the device to the column.

[0011] A first lead screw is rotatably mounted in the base. A first motor drives the first lead screw to rotate. A first lead screw nut is threaded onto the first lead screw and is fixed to the support frame. When the first motor drives the first lead screw to rotate, the first lead screw nut moves on the first lead screw, thereby moving the support frame.

[0012] The second clamping assembly includes two opposing L-shaped clamps, which together form a U-shaped support space for placing the crossbeam. The side plates of the two L-shaped clamps clamp the two sides of the crossbeam. The L-shaped clamps support the crossbeam, and the side plates of the two L-shaped clamps laterally limit the position of the crossbeam.

[0013] The support frame is U-shaped, with fixing grooves on the inner sides of the two side plates. A second lead screw is rotatably mounted in each groove. A second motor drives the second lead screw to rotate. Each second lead screw has a threaded nut, which is connected to one of two L-shaped clamping components. When the second motor drives the second lead screw to rotate, the second lead screw nut moves along the lead screw, thereby causing the L-shaped clamping components to move vertically.

[0014] Hydraulic cylinders are fixed to the inner sides of the two second lead screw nuts. The piston rods of the hydraulic cylinders are fixed to the L-shaped clamping parts. The hydraulic cylinders drive the two L-shaped clamping parts to move towards each other or away from each other. Through the above structure, the distance between the two L-shaped clamping parts can be changed, making it easier to tighten or loosen the crossbeam.

[0015] Each of the two L-shaped clamping members has a first rubber pad on the inner side of its side plate. The first rubber pads allow the crossbeam to make elastic contact with the L-shaped clamping member.

[0016] A second rubber pad is installed on the inner side wall of each of the two racks. The second rubber pad allows the rack to make elastic contact with the upright.

[0017] Several rotating posts are rotatably mounted on the base plates of the two L-shaped clamping members. The axial direction of the rotating posts is parallel to the length direction of the crossbeam, and the bottom surface of the crossbeam abuts against the rotating posts. The rotating posts reduce mutual wear between the L-shaped clamping members and the crossbeam at the contact points. Attached Figure Description

[0022] The present invention will be further described below with reference to embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0023] Reference Figure 1-3 This application discloses an auxiliary device for connecting prefabricated steel structure beams and columns, used for auxiliary positioning when beams 6 and columns 1 are installed together. It includes a first clamping component and a second clamping component. The first clamping component is used to clamp the column 1. A base 3 is connected to one side of the first clamping component. A horizontally movable support frame 4 is provided on the base 3. The second clamping component is vertically movable and is provided on the support frame 4. The second clamping component is used to clamp the beams 6.

[0024] In this embodiment, the first clamping assembly includes two geometric frames 2, which are symmetrically ringed around the column 1 and fastened to each other by bolts. The distance between the two geometric frames 2 is adjusted by the bolts, thereby stably clamping the two geometric frames 2 onto the column 1. The outer wall of one of the geometric frames 2 is fixed to one end of the base.

[0025] In this embodiment, the base 3 is a rectangular groove, in which a first lead screw 32 is disposed. The length direction of the first lead screw 32 is perpendicular to the axis of the column 1. One end of the first lead screw 32 is rotatably connected to one end of the rectangular groove, and a first motor 31 is fixed to the other end of the rectangular groove. The output shaft of the first motor 31 is coaxially fixed to the other end of the first lead screw 32. The first motor 31 drives the first lead screw 32 to rotate. A first lead screw nut 33 is threaded onto the first lead screw 32, and the top end of the first lead screw nut 33 is fixed to the bottom end of the support frame 4. When the first motor 31 drives the first lead screw 32 to rotate, the first lead screw nut 33 moves on the first lead screw 32, thereby driving the support frame 4 to move.

[0026] In this embodiment, the second clamping assembly includes two opposing L-shaped clamping members 5, which together form a U-shaped support space for placing the crossbeam 6. The side plates of the two L-shaped clamping members 5 clamp the two sides of the crossbeam 6. The L-shaped clamping members 5 support the crossbeam 6, and the side plates of the two L-shaped clamping members 5 laterally limit the position of the crossbeam 6, thereby defining the position of the crossbeam 6.

[0027] In this embodiment, the support frame 4 is U-shaped. The inner sides of the two side plates of the U-shaped support frame 4 are respectively provided with fixing grooves 41, and the opening directions of the fixing grooves 41 are corresponding. A second lead screw 44 is rotatably installed in each of the two fixing grooves 41. Specifically, the bottom end of the second lead screw 44 is rotatably connected to the inner bottom surface of the fixing groove 41. A second motor 45 is fixed to the inner top surface of the fixing groove 41. The output shaft of the second motor 45 is coaxially fixed with the second lead screw 44, and the second lead screw 44 is driven to rotate by the second motor 45. A second lead screw nut 43 is threaded onto each of the two second lead screws 44. A hydraulic cylinder 42 is fixed to the inner side of the two second lead screw nuts 43. The front end of the piston rod of the hydraulic cylinder 42 is fixed to the outer side of the side plate of the L-shaped clamp 5. When the second motor 45 drives the second lead screw 44 to rotate, the second lead screw nut 43 moves on the second lead screw 44, thereby driving the L-shaped clamping member 5 to move vertically; the hydraulic cylinder 42 drives the two L-shaped clamping members 5 to move towards each other or away from each other, thereby changing the distance between the two L-shaped clamping members 5, which makes it easier to tighten or loosen the crossbeam 6.

[0028] In this embodiment, the inner sides of the side plates of the two L-shaped clamping members 5 are respectively provided with first rubber pads 51. The first rubber pads 51 enable the crossbeam 6 to elastically contact the L-shaped clamping members 5.

[0029] In this embodiment, a second rubber pad 21 is provided on the inner sidewall of each of the two racks 2. The second rubber pad 21 enables the rack 2 to elastically contact the column 1.

[0030] In this embodiment, several rotating posts 52 are rotatably mounted on the base plates of the two L-shaped clamping members 5. The axial direction of the rotating posts 52 is parallel to the length direction of the crossbeam 6, and the bottom surface of the crossbeam 6 abuts against the rotating posts 52. The rotating posts 52 reduce mutual wear at the contact points between the L-shaped clamping members 5 and the crossbeam 6 when the clamping members 5 are fastening the crossbeam 6.

[0031] In use, two L-shaped frames 2 are symmetrically wrapped around the column 1 and fixed with bolts. Then, the hydraulic cylinder 42 is adjusted to retract, so that the distance between the side plates of the two L-shaped clamps 5 is greater than the width of the crossbeam 6. The crossbeam 6 is then hoisted and placed on the two L-shaped clamps 5, with the bottom surface of the crossbeam 6 abutting against the bottom plate of the L-shaped clamps 5. Then, the hydraulic cylinder 42 is controlled to extend, so that the side plates of the two L-shaped clamps 5 are tightly pressed against both sides of the crossbeam 6, providing horizontal limiting clamping for the crossbeam 6. At the same time, the clamps of the L-shaped clamps 5... The beam 6 is held parallel to the mounting surface of the column 1 to prevent it from tilting. Then, two second motors 45 are turned on at the same time to rotate two second lead screws 44, which move the second lead screw nuts 43 at the same time, lifting the beam 6 to the target installation height. Then, the first motor 31 drives the first lead screw 32 to rotate, which moves the first lead screw nut 33 to move the support frame 4, bringing the beam 6 closer to the column 1 until the beam 6 and the column 1 come into contact. The workers then connect the beam 6 and the column 1.

[0032] The auxiliary device of this utility model can stably connect the column 1 and the crossbeam 6. The first clamping component clamps the column 1, fixing the device on the column 1. The second clamping component clamps the crossbeam 6, making the crossbeam 6 perpendicular to the column 1. The second clamping component can move vertically on the support frame 4, which facilitates the vertical movement of the crossbeam 6, thereby adjusting the installation position of the crossbeam 6 and the column 1. The support frame 4 can move horizontally on the base 3, which facilitates the horizontal movement of the crossbeam 6, making the crossbeam 6 abut against the column 1, and facilitating the welding and fixing of the abutment position between the crossbeam 6 and the column 1.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
