Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel structure expansion joint structures, in particular to an adjustable steel structure factory building expansion joint structure. Background Art
[0002] A building expansion joint is a structural joint that is set at an appropriate position along the construction joint direction of a building or structure to prevent cracks or damage to the structure due to climate temperature changes (thermal expansion and contraction). Expansion joints are also required during the construction of steel structure factories. During the production of the walkway slabs of the factory crane beams, the walkway slabs are usually welded to the steel columns. With this solution, when the temperature difference between day and night is large, or when the seasons change, the walkway slabs will expand and contract due to heat, causing deformation, affecting their use during construction and maintenance.
[0003] In view of this, we propose an adjustable expansion joint structure for steel structure workshops. The two sides of the walkway plate are fixed by clamps on both sides. Through the expansion and contraction of this structure, the walkway plate can be expanded and contracted normally to prevent the deformation of the walkway plate. At the same time, a built-in inspection ruler can observe the shrinkage changes of the walkway plate. Utility Model Content

The two clamps are connected to the bridge frame together. The clamp and the bridge frame are connected and fixed by a limit bolt.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1 - Figure 4 , the utility model provides a technical solution:
[0025] An adjustable steel structure factory expansion joint structure, including a clamp 1 and a bridge frame 2, wherein the clamp 1 is provided with two groups, and the two groups of the clamps 1 are respectively arranged on both sides of the bridge frame 2, the clamp 1 includes a limit card slot 13 and a clamp plate 11, the limit card slot 13 is installed on the side of the bridge frame 2, the surface of the limit card slot 13 is provided with a clamp plate 11, the surface of the clamp plate 11 passes through a fixing bolt 12, and the surface of the limit card slot 13 is provided with a limit bolt 14, the bridge frame 2 includes a main frame body 21 and a limiter 22, the limiter 22 is provided with four, and the four limiters 22 are respectively It is arranged on both sides of the main frame 21, and the end of the limit bolt 14 is threadedly connected to the limiter 22. A folding plate 25 is arranged on the top of the main frame 21. The two clamps 1 are connected to the bridge frame 2 together. The clamp 1 and the bridge frame 2 are connected and fixed by the limit bolt 14. The limit bolt 14 passes through the clamp 1 and is fixed inside the limit ring 221 of the bridge frame 2. The limit ring 221 is movable, so that when the walkway board fixed at one end of the clamp 1 is extended or retracted, the walkway board is stretched or squeezed by the splint 11, thereby releasing the deformation of the walkway board, preventing the walkway board from being deformed due to the extrusion of the end due to thermal expansion and contraction, thereby ensuring the use of the walkway board.
[0026] The limiter 22 includes a limit ring 221 and a return spring 222. The return springs 222 are arranged on both sides of the limit ring 221, and the limit ring 221 can be automatically reset by the return springs 222. At the same time, damping is maintained between the clamp 1 and the bridge frame 2 to prevent unnecessary shaking between the clamp 1 and the bridge frame 2.
[0027] A hydraulic column 223 is arranged inside the return spring 222, and the hydraulic column 223 is connected to a detection ruler. The inner tube diameter of the hydraulic column 223 is the same as the inner tube diameter of the detection ruler. Through the same diameter, the hydraulic column 223 is extended or retracted to a certain height, and the liquid level inside the detection ruler is synchronized, so as to judge the extension and retraction distance between the clamp 1 and the bridge frame 2.
[0028] A mounting bolt 24 is provided on one side of the hydraulic column 223, and the mounting bolt 24 passes through the inner wall of the main frame 21. The top of the mounting bolt 24 contacts the limiting ring 221 to control the distance between the mounting bolt and the limiting ring 221, thereby controlling the expansion and contraction variable between the clamp 1 and the bridge frame 2 to prevent the expansion and contraction variable between the clamp 1 and the bridge frame 2 from being too large, causing the walkway plates at both ends of the clamp 1 to shake.
[0029] There are two folding plates 25 in total. The two folding plates 25 are respectively arranged on both sides of the main frame 21, and the walkway plates at both ends are connected by the two folding plates 25.
[0030] The main frame 21 adopts a "J"-shaped structure, and an "X"-shaped reinforcing rib is arranged inside the main frame 21. The internal reinforcing structure of the main frame 21 can enhance the strength of the main frame 21 itself and prevent the main frame 21 from deforming.
[0031] When the adjustable steel structure factory expansion joint structure of the utility model is used, the clamp 1 needs to be fixed at the two ends of the walkway plate to be connected, and the bridge frame 2 is installed between the two clamps 1, and then the fixing bolt 12 is tightened so that the clamp plate 11 of the clamp 1 is fixed to the surface of the walkway plate, and then the limit bolt 14 is tightened. The end of the limit bolt 14 passes through the limit slot 13 of the clamp 1 and is connected to the inside of the limit ring 221 of the limiter 22, so that the bridge frame 2 connects the clamps 1 on both sides, and the folding plate is flipped. 25, so that the folding plate 25 connects the walkway plates at both ends, and then adjusts the distance between the mounting bolt 24 and the limiter 22, and controls the range of motion between the clamp 1 and the bridge frame 2 by controlling the distance between the mounting bolt 24 and the limit ring 221. When the distance between the mounting bolt 24 and the limit ring 221 is enlarged, the range of motion of the limit ring 221 can be enlarged, and when the distance between the mounting bolt 24 and the limit ring 221 is reduced, the range of motion of the limit ring 221 is reduced accordingly, so as to prevent the deformation of the clamp 1 and the bridge frame 2 from being too large. , causing the walkway to shake. When the walkway plate is stretched or extended due to thermal expansion and contraction, the walkway plate will drive the clamp 1 at one end to move, so that the clamp 1 shrinks inward or stretches outward. The limit slot 13 of the clamp 1 drives the limit ring 221 to move through the limit bolt 14, compressing the spring on one side of the limit ring 221, and preventing the walkway plate from being deformed due to thermal expansion and contraction by squeezing the end portion through the extension deformation between the clamp 1 and the bridge frame 2. When the limit ring 221 is displaced, the limit ring 221 synchronously compresses the hydraulic column 223. The hydraulic oil inside the hydraulic column 223 is pumped into the inside of the inspection ruler 23 through a pipeline. By observing the liquid level height inside the inspection ruler and the change in the liquid level height, the telescopic distance between the clamp 1 and the bridge frame 2 and the telescopic distance of the steel structure can be understood. Compared with traditional welding fixation, in addition to preventing the deformation of the walkway caused by thermal expansion and contraction, the adjustable mounting bolts can control the telescopic gap between the clamp 1 and the bridge frame 2 to prevent the telescopic gap from being too large or too small.
