Description

Technical Field

[0001] This utility model relates to the field of steel structures, and in particular to a temporary connection device for rapid positioning of steel structure beams and columns. Background Technology

[0002] Steel structure is a building structure that uses steel as the main material to construct a load-bearing frame. It is widely used in large or long-span projects such as industrial plants, high-rise buildings, bridges, stadiums, and airport terminals.

[0003] A temporary connection device for rapid positioning of steel structure beams and columns is a special auxiliary tool or mechanical structure used for rapid alignment and temporary fixation of beams and columns during steel structure construction.

[0004] An existing temporary connection device for rapid positioning of steel structure beams and columns has the following shortcomings: The existing temporary connection technology for steel structure beams and columns has obvious operational inconveniences. During construction, the column must first be vertically fixed in the designed position, and then the beam is lifted to a suitable height to connect with the column using hoisting equipment. In this process, the fastening connection between the two relies entirely on bolts. In order to ensure the connection strength and stability, a large number of bolts are often required. Workers need to align, insert and tighten multiple bolts one by one at high altitude, which not only consumes a lot of time and manpower, but also easily leads to alignment deviations due to the large number of bolts, further increasing the difficulty of operation and resulting in low overall installation efficiency. Utility Model Content

[0005] This invention utilizes elastic force to drive the insertion rod to automatically extend into the crossbeam insertion hole, eliminating the need for manual alignment of each bolt hole, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a temporary connection device for rapid positioning of steel structure beams and columns, comprising a positioning mechanism, wherein a connecting mechanism is slidably connected to the outer wall of the positioning mechanism; the positioning mechanism includes a fixing plate, a set of connecting plates is fixedly connected to the inner wall of the fixing plate, a set of sliders is slidably connected to the inner wall of the connecting plate, a set of insert rods is fixedly connected to the outer wall of the sliders, a set of first compression springs is fixedly connected to the outer wall of the sliders, guide blocks are slidably connected to the inner walls of the connecting plates, limiting rods are fixedly connected to the inner walls of the connecting plates, second compression springs are sleeved on the outer walls of the limiting rods, and a connecting rope is fixedly connected to the outer wall of the sliders. Through the above components, there is no need for manual alignment of bolts one by one, and the insert rods can automatically adapt to the insertion holes under the elastic force of the first and second compression springs, reducing the amount of manual operation at height.

[0007] Preferably, a positioning block is fixedly connected to the outer wall of the fixing plate, and a set of cylinders is fixedly connected to the top of the fixing plate. The inner wall of the cylinders is slidably connected to the outer wall of the connecting rope. The positioning block can match the positioning groove of the beam and column body, so that the reference position can be quickly found during hoisting, avoiding repeated adjustment of the beam height and shortening the alignment time.

[0008] Preferably, a set of locking blocks are fixedly connected to the outer wall of the fixing plate, and a set of first bolts are threaded through the outer wall of the locking blocks. The locking blocks can fit into the locking grooves of the beam and column body and are fixed in conjunction with the first bolts.

[0009] Preferably, the outer wall of the insertion rod and the connecting rope is slidably connected to the inner wall of the connecting plate, one end of the first compression spring is fixedly connected to the outer wall of the slider, and the other end of the first compression spring is fixedly connected to the inner wall of the connecting plate. The two ends of the first compression spring fix the slider and the connecting plate respectively. After pulling the connecting rope, it is released, and the insertion rod can be automatically inserted into the insertion hole under the action of elasticity without manual pushing.

[0010] Preferably, the outer wall of the limiting rod is slidably connected to the inner wall of the guide block, and the limiting rod limits the sliding direction of the guide block to prevent positioning deviation caused by guide block offset.

[0011] Preferably, one end of the second compression spring is fixedly connected to the outer wall of the guide block, and the other end of the second compression spring is fixedly connected to the inner wall of the connecting plate. The second compression spring can play an auxiliary role, allowing the insertion rod to be inserted into the insertion hole more forcefully.

[0012] Preferably, the bottom of the fixing plate is slidably connected to a right-angle rib plate, and a set of second bolts are threaded through the outer wall of the right-angle rib plate. The right-angle rib plate forms a triangular support structure to distribute the pressure of the crossbeam on the fixing plate.

[0013] Preferably, the inner wall of the fixing plate is slidably connected to a crossbeam, the outer wall of the crossbeam is provided with an insertion hole, and the bottom of the crossbeam is provided with a first threaded hole. The inner wall of the first threaded hole is threadedly connected to the outer wall of the second bolt. The second bolt connects the crossbeam and the right-angle rib plate through the first threaded hole. With the positioning function of the insertion rod, a dual guarantee of mechanical positioning and bolt fixing is formed to avoid temporary connection loosening.

[0014] Preferably, the connecting mechanism includes a beam-column body, the outer wall of which is provided with a positioning groove and a set of slots, the inner wall of which is provided with a second threaded hole, the inner wall of which is threadedly connected to the outer wall of the first bolt.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, efficient and precise alignment and installation are achieved through the sliding cooperation of the positioning mechanism and the connecting mechanism. In the positioning mechanism, the slider, the insertion rod, and the first compression spring work together to drive the insertion rod to automatically insert into the crossbeam insertion hole using elastic force, eliminating the need for manual adjustment of bolt alignment one by one, significantly improving assembly efficiency. The guide block, the limiting rod, and the second compression spring work together to assist in applying force. At the same time, the two sliders are driven by the connecting rope, greatly reducing manual intervention in high-altitude operations. This is more convenient and efficient than traditional single-bolt operation. In addition, the positioning block set on the fixed plate can quickly embed into the positioning groove of the beam and column to achieve preliminary accurate positioning. The cylindrical structure guides and limits the connecting rope, optimizes transmission performance, further shortens the alignment time, and improves the reliability and safety of the overall installation.

[0017] 2. In this utility model, after the card block and the card slot are attached, they are fixed by the first bolt. The right-angle stiffening plate is connected to the crossbeam and the beam column body by the second bolt, forming a stable triangular support structure, which effectively disperses the force and improves the connection strength. The insertion rod realizes mechanical quick positioning. With the fastening effect of the bolt, a dual guarantee mechanism of positioning and locking is formed, which effectively prevents the temporary connection from loosening during construction, significantly reduces the safety risk caused by unstable connection, and improves the safety and reliability of operation.
