Description
A steel pipe concrete support connection device with a reinforced structure Technical Field
[0001] This utility model relates to the field of steel pipe concrete support technology, specifically a steel pipe concrete support connection device with a reinforced structure. Background Technology
[0002] The shape of the steel pipe concrete support is no different from that of ordinary steel pipes. After the splicing is completed, a large amount of concrete mortar needs to be poured into the hollow pipe to fill the inside of the tank and prevent the support composed of steel pipes from collapsing under the weight. In order to quickly assemble, connecting devices are often installed between adjacent steel pipes.
[0003] In most cases, the connection device of ordinary steel pipe concrete support is selected according to the diameter of the steel pipes on both sides, and then the stirrups are added to prevent the support from collapsing or the concrete slurry from overflowing from the steel pipes. This type of structure is not easy to maintain the connection between the steel pipes for a long time and is prone to collapse.
[0004] Now, a novel steel-concrete composite support connection device with a reinforced structure is proposed to solve the above problems. Summary of the Invention
[0005] The purpose of this utility model is to provide a steel pipe concrete support connection device with a reinforced structure to solve the problem of insufficient connection strength mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel pipe concrete support connection device with a reinforced structure, comprising a left steel pipe and a splicing pipe. The splicing pipe is inserted into the right side of the inside of the left steel pipe, and a right steel pipe is sleeved on the outside of the right side of the splicing pipe. Threaded holes are provided laterally at the top and bottom ends of the splicing pipe. Sliding grooves are provided at the top and bottom ends of the left and right steel pipes, and threaded blocks are movably connected in the sliding grooves. Push blocks are fixed on the sides of the threaded blocks. A screw is threaded laterally between the threaded blocks and the threaded holes, and nuts are sleeved on both sides of the screw.
[0007] As a further technical solution of this utility model, the left steel pipe and the right steel pipe have the same inner and outer diameters, and the left steel pipe and the right steel pipe are symmetrically sleeved on both sides of the splicing pipe.
[0008] As a further technical solution of this utility model, the push block is symmetrically attached to both sides of the splicing pipe, and the nut rotates horizontally along the surface of the screw.
[0009] As a further technical solution of this utility model, a diversion chamber is provided around the inside of the splicing pipe, and a channel is provided at the top of the diversion chamber. A threaded wall is provided above the inside of the channel, and a bolt is installed in the threaded wall. A screw block is fixed at the top of the bolt. Grooves are provided at the upper, lower, left and right corners of the diversion chamber. Annular grooves are provided on the right inner wall of the left steel pipe and the left inner wall of the right steel pipe, and a threaded wall is provided on the inner wall of the annular groove.
[0010] As a further technical solution of this utility model, the surface texture of the bolt matches the threaded wall, and the bolt rotates vertically above the channel.
[0011] As a further technical solution of this utility model, the slot is fitted to the annular groove, and the channel is connected to the diversion chamber and the slot.
[0012] As a further technical solution of this utility model, the right side inside the left steel pipe and the left side inside the right steel pipe are respectively fixed with retaining rings, and the retaining rings are provided with circular grooves. A horizontal pipe is welded horizontally at the center of the splicing pipe.
[0013] As a further technical solution of this utility model, the retaining rings are symmetrically attached to both sides of the horizontal tube, and the retaining rings and the horizontal tubes are on the same horizontal plane.
[0014] Compared with the prior art, the beneficial effects of this utility model are: the steel pipe concrete support connection device with reinforced structure not only improves the connection strength and achieves reinforcement with cement grout, but also facilitates the flow of concrete mortar.
[0015] (1) By setting screw holes horizontally at the top and bottom of the splicing pipe, the left steel pipe and the right steel pipe are respectively sleeved on both sides of the splicing pipe. Then, push the threaded block along the slide groove so that the push block on the side of the threaded block fits against the surface of the splicing pipe. Align the threaded block and the screw hole in the same horizontal direction, screw in the screw rod for reinforcement, and put the nuts on both sides and tighten this object. Force can be applied from four directions at the same time to tighten and fix the left steel pipe and the right steel pipe on both sides of the splicing pipe.
[0016] (2) By setting a diversion chamber around the inside of the splicing pipe, when the splicing pipe is installed between the left steel pipe and the right steel pipe, each slot corresponds to the annular groove on both sides. After the bolt in the threaded wall one is unscrewed by the screw block, the fine cement slurry is injected into the channel by the pressure pump. The cement slurry sprays out from the slot through the channel and the diversion chamber and accumulates in the annular groove. After solidification, it is fixed together with the threaded wall two, which can improve the gripping force of the splicing pipe on both sides of the pipe body and prevent the three from separating again.
[0017] (3) By fixing retaining rings on the right side inside the left steel pipe and the left side inside the right steel pipe respectively, when the left steel pipe and the right steel pipe are connected, the horizontal pipe at the center of the splicing pipe passes through the annular groove and fits together with the retaining ring. The diameter of the horizontal pipe is smaller than that of the retaining ring, so that the horizontal pipe passes through and fits tightly inside the retaining ring. The pipe support assembled in this way will not be blocked when receiving concrete grout for filling, and the arch will flow smoothly. Attached Figure Description

[0025] The left steel pipe 1 and the right steel pipe 10 have the same inner and outer diameters. The left steel pipe 1 and the right steel pipe 10 are symmetrically sleeved on both sides of the splicing pipe 6. The push block 5 is symmetrically attached to both sides of the splicing pipe 6. The nut 3 rotates horizontally along the surface of the screw 8.
[0026] Specifically, as shown in Figures 1 and 2, the left steel pipe 1 and the right steel pipe 10 are respectively fitted onto the two sides of the splicing pipe 6. Then, the threaded block 4 is pushed along the slide groove 2 so that the push block 5 on the side of the threaded block 4 fits against the surface of the splicing pipe 6. The threaded block 4 and the screw hole 7 are aligned in the same horizontal direction. The screw rod 8 is screwed in for reinforcement. Nuts 3 are fitted on both sides and tightened to lock the connection structure.
[0027] A diversion chamber 18 is provided around the inside of the splicing pipe 6, and a channel 16 is provided at the top of the diversion chamber 18. A threaded wall 15 is provided above the inside of the channel 16, and a bolt 14 is installed in the threaded wall 15. A rotating block 13 is fixed at the top of the bolt 14. A slot 19 is provided at the upper, lower, left and right corners of the diversion chamber 18. An annular groove 9 is provided on the right inner wall of the left steel pipe 1 and the left inner wall of the right steel pipe 10, and a threaded wall 20 is provided on the inner wall of the annular groove 9.
[0028] The surface texture of bolt 14 matches the threaded wall 15. Bolt 14 rotates vertically above channel 16. Slot 19 fits into annular groove 9. Channel 16 is connected to flow chamber 18 and slot 19.
[0029] Specifically, as shown in Figures 1 and 3, when the splicing pipe 6 is installed between the left steel pipe 1 and the right steel pipe 10, each slot 19 corresponds exactly to the annular grooves 9 on both sides. After the bolt 14 in the threaded wall 15 is unscrewed by the screw block 13, the fine cement slurry is injected into the channel 16 by a pressure pump, so that the cement slurry is sprayed out from the slot 19 through the channel 16 and the diversion chamber 18 and accumulates in the annular groove 9. After solidification, it is fixed together with the threaded wall 20.
[0030] A retaining ring 12 is fixed to the right side inside the left steel pipe 1 and the left side inside the right steel pipe 10, and a circular groove 17 is provided in the retaining ring 12. A horizontal pipe 11 is welded to the center inside the splicing pipe 6.

[0031] Specifically, as shown in Figures 1, 3, and 4, when the left steel pipe 1 and the right steel pipe 10 are connected, the horizontal pipe 11 at the center of the splicing pipe 6 passes through the annular groove 9 and fits together with the retaining ring 12. The diameter of the horizontal pipe 11 is smaller than that of the retaining ring 12, so that the horizontal pipe 11 passes through and fits tightly inside the retaining ring 12.

[0032] Working Principle: In use, the left steel pipe 1 and right steel pipe 10 are first fitted onto both sides of the splicing pipe 6. Then, the threaded block 4 is pushed along the sliding groove 2, causing the push block 5 on the side of the threaded block 4 to fit against the surface of the splicing pipe 6. The threaded block 4 and threaded hole 7 are aligned horizontally, and the screw rod 8 is screwed in for reinforcement. Nuts 3 are then fitted onto both sides and tightened. When the left steel pipe 1 and right steel pipe 10 are fully fitted, the horizontal pipe 11 at the center of the splicing pipe 6 passes through the annular groove 9 and fits against the retaining ring 12. The diameter of the horizontal pipe 11 is smaller than that of the retaining ring 12, allowing... The horizontal tube 11 is inserted and tightly fitted inside the retaining ring 12. The pipe support assembled in this way will not be blocked when receiving concrete grout. At this time, each slot 19 corresponds to the annular groove 9 on both sides. After the bolt 14 in the threaded wall 15 is unscrewed by the screw block 13, the fine cement grout is injected into the channel 16 by the pressure pump. The cement grout is sprayed out from the slot 19 through the channel 16 and the diversion chamber 18 and accumulates in the annular groove 9. After solidification, it is fixed together with the threaded wall 20, which can improve the gripping force of the splicing pipe 6 on the pipes on both sides.
