Description

Technical Field

[0001] This utility model relates to the field of prefabricated building processing and manufacturing technology, and in particular to a quick connection tool for prefabricated building construction nodes. Background Technology

[0002] Prefabricated joint connection tools refer to the tools and equipment used in prefabricated buildings to connect different components. These tools are mainly used to ensure precise docking and firm connection between components, thereby improving the overall stability and safety of the building. In traditional beam-column fully welded joints, the upper and lower flanges and webs of the beam are welded to the column on site. Although this connection is a rigid connection, the joint has poor ductility and is prone to brittle failure in earthquakes. Moreover, the need for on-site welding greatly affects the construction speed and quality, causes environmental pollution, and is not suitable for prefabricated steel structures. At the same time, due to the large welding area, it is easy to generate large residual stress, which affects the stress performance of the joint.

[0003] Existing technologies, such as CN219240858U, disclose a prefabricated steel structure beam-column joint connection structure, including a support column. The support column has a T-shaped groove on its front side. A mounting plate is bolted to the front side of the support column. A connector is fixedly connected to the center of the front side of the mounting plate. A fixing plate is welded to the center of the bottom end of the connector. A straightening mechanism is installed on both sides of the fixing plate. Straightening plates are hinged to both sides of the connector. A fixing seat is fixedly connected to the center of the bottom end of the straightening plate. A crane moves the main beam to the upper end of the connector. The straightening mechanism, driven by the output of a servo motor, rotates the main gear, causing the moving parts to move horizontally, which in turn rotates the connecting arm, thus rotating the straightening plates. Because symmetrical straightening plates are hinged to both sides of the connector, the main beam is precisely moved to the center of the connector, improving the efficiency and safety of the beam installation and avoiding manual labor.

[0004] To address the issue of connecting building formwork nodes using existing equipment, which primarily uses welding to connect and fix columns, disassembly requires numerous auxiliary tools and can damage some columns during the process, resulting in material waste. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of existing methods for connecting and fixing columns, which mostly involve welding. When disassembling the columns, many auxiliary tools are needed, and some columns may be damaged during the disassembly process, resulting in a waste of materials. Therefore, this utility model proposes a quick connection tool for prefabricated building construction nodes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a quick connection tool for prefabricated building construction nodes, comprising a first support column, a second support column, and a connecting component. The second support column is disposed on the surface of the first support column, and the connecting component is disposed on the surface of the first support column. The connecting component includes an adjustment groove, which is formed on the surface of the first support column, and a bidirectional lead screw is rotatably connected to the inner wall of the adjustment groove.

[0007] Furthermore, the surface of the bidirectional lead screw is provided with an L-shaped rod, and there are two sets of L-shaped rods arranged symmetrically. The surface of the L-shaped rod is provided with a threaded hole, and the bidirectional lead screw is threaded through the inner wall of the threaded hole.

[0008] Furthermore, a locking block is fixed to the surface of the second support column, the locking block engages with the inner wall of the adjustment groove, a fixing hole is opened on the surface of the locking block, and the L-shaped rod is inserted and connected to the inner wall of the fixing hole.

[0009] Furthermore, the inner wall of the adjusting groove is provided with a rotating groove, and a turntable is rotatably connected to the inner wall of the rotating groove. The turntable is fixedly connected to the surface of the bidirectional lead screw.

[0010] Furthermore, the surface of the turntable is provided with grooves, and the number of grooves is multiple and arranged in a circumferential manner, while the surface of the first support column is provided with a sliding groove.

[0011] Furthermore, a tension spring is fixedly connected to the inner wall of the slide groove, and a rod is fixedly connected to the end of the tension spring away from the slide groove. The rod is slidably connected to the inner wall of the slide groove.

[0012] Furthermore, the upper surface of the turntable is provided with positioning holes, and the number of positioning holes is multiple and arranged in a circular array. The insertion rod is inserted and connected to the inner wall of the positioning hole. A sliding rod is fixedly connected to the surface of the insertion rod, and the sliding rod is slidably connected to the inner wall of the slide groove. A lever is fixedly connected to the surface of the sliding rod.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a connecting component, the L-shaped rod is more convenient to use when connecting the support column. To this end, the locking block on the surface of the second support column is inserted into the adjustment groove of the first support column, and then the lever is pushed upward, so that the tension spring is compressed and the insertion rod leaves the inner wall of the positioning hole. Then, the groove on the surface of the turntable is rubbed by hand to increase the friction, and then the bidirectional screw is driven to rotate.

[0015] 2. In this utility model, after the bidirectional lead screw drives the two sets of L-shaped rods to be inserted into the fixing holes, and the second support column is stably connected and fixed to the first support column, the lever is then released, causing the tension spring to lose its force and expand. The spring then pushes the insertion rod to slide along the inner wall of the groove, inserting it into the positioning hole. The turntable is then fixed, preventing the bidirectional lead screw from rotating arbitrarily. The connection components facilitate the connection of the support columns, avoiding the need for numerous auxiliary tools during disassembly, which could damage some support columns and waste materials. This effectively improves the stability of the equipment. Attached Figure Description

[0023] Please see Figures 1-5 This utility model provides a technical solution: a quick connection tool for prefabricated building construction nodes, including a first support column 1, a second support column 2, and a connecting component 3. The second support column 2 is disposed on the surface of the first support column 1, and the connecting component 3 is disposed on the surface of the first support column 1.

[0024] The specific settings and functions of connection component 3 will be explained below.

[0025] In this embodiment: the connecting component 3 includes an adjustment groove 31, which is formed on the surface of the support column 1, and a bidirectional lead screw 32 is rotatably connected to the inner wall of the adjustment groove 31.

[0026] The effect achieved by the above components is that by setting the bidirectional lead screw 32, it is easy to drive the two sets of L-shaped rods 33 to perform reverse transmission, so that the L-shaped rods 33 fix the locking block 35.

[0027] Specifically, the surface of the bidirectional lead screw 32 is provided with L-shaped rods 33, and there are two sets of L-shaped rods 33 arranged symmetrically. The surface of the L-shaped rods 33 is provided with threaded holes 34, and the bidirectional lead screw 32 is driven by the inner wall of the threaded holes 34.

[0028] The effect achieved by the above components is that by setting up the transmission between the bidirectional lead screw 32 and the threaded hole 34, it is convenient to perform bidirectional transmission of the L-shaped rod 33.

[0029] Specifically, a locking block 35 is fixed to the surface of the support column 2. The locking block 35 engages with the inner wall of the adjustment groove 31. A fixing hole 36 is opened on the surface of the locking block 35. The L-shaped rod 33 is inserted and connected to the inner wall of the fixing hole 36.

[0030] The effect achieved by the above components is that by setting the connection between the L-shaped rod 33 and the fixing hole 36, it is easy to make the support column 2 stably connected and fixed to the support column 1.

[0031] Specifically, the inner wall of the adjusting groove 31 is provided with a rotating groove 37, and a turntable 38 is rotatably connected to the inner wall of the rotating groove 37. The turntable 38 is fixedly connected to the surface of the bidirectional lead screw 32.

[0032] The effect achieved by the above components is that by setting up the turntable 38, it is easy to drive the bidirectional lead screw 32 to rotate.

[0033] Specifically, the surface of the turntable 38 is provided with grooves 39, and the number of grooves 39 is multiple and arranged in a circular pattern. The surface of the support column 1 is provided with a sliding groove 310.

[0034] The effect achieved by the above-mentioned components is that by setting the groove 39, the friction of the surface of the turntable 38 is increased, making it easier for the operator to rotate the turntable 38.

[0035] Specifically, a tension spring 311 is fixedly connected to the inner wall of the slide groove 310, and a rod 312 is fixedly connected to the end of the tension spring 311 away from the slide groove 310. The rod 312 is slidably connected to the inner wall of the slide groove 310.

[0036] The effect achieved by the above components is that by setting the tension spring 311, the expansion force of the tension spring 311 can drive the insertion rod 312 to move after the insertion rod 312 is unrestrained.

[0037] Specifically, the upper surface of the turntable 38 is provided with positioning holes 313. The number of positioning holes 313 is multiple and arranged in a circular array. The insertion rod 312 is inserted and connected to the inner wall of the positioning hole 313. A sliding rod 314 is fixedly connected to the surface of the insertion rod 312. The sliding rod 314 is slidably connected to the inner wall of the slide groove 310. A lever 315 is fixedly connected to the surface of the sliding rod 314.

[0038] The effect achieved by the above components is as follows: by setting the connection between the insertion rod 312 and the positioning hole 313, the turntable 38 is fixed, the bidirectional lead screw 32 is fixed, and then the L-shaped rod 33 stably fixes the locking block 35 inside the support column 1, so that the connection is stable.

[0039] Working principle: By setting the connecting component 3, the L-shaped rod 33 is more convenient to use when connecting the support column. To this end, the locking block 35 on the surface of the second support column 2 is inserted into the adjustment groove 31 of the first support column 1. Then, the lever 315 is pushed upward, so that the tension spring 311 is compressed and the insertion rod 312 is separated from the inner wall of the positioning hole 313. Then, the groove 39 on the surface of the turntable 38 is rubbed by hand to increase the friction, which then drives the bidirectional lead screw 32 to rotate.

[0040] After the bidirectional lead screw 32 drives the two sets of L-shaped rods 33 to be inserted into the fixing hole 36, and the second support column 2 is stably connected and fixed to the first support column 1, the lever 315 is released, causing the tension spring 311 to lose its force and expand. Then, the insertion rod 312 is pushed to slide along the inner wall of the slide groove 310 and inserted into the positioning hole 313. Then, the turntable 38 is fixed, so that the bidirectional lead screw 32 no longer rotates randomly. By setting the connecting component 3, it is easy to connect the support column, avoiding the need for many auxiliary tools to disassemble the support column, and avoiding damage to some support columns during the disassembly process, which is more wasteful of materials. This effectively improves the stability of the equipment.
