Description

Technical Field

[0001] The present invention relates to the field of crossbeam suspension modules, and specifically to a self-suspending formwork device for concrete beams. Background Art

[0002] The self-selected formwork device for concrete beams is a formwork system that utilizes the existing structure of a building or specially provided suspension points. Through a suspension system, the formwork and its supporting structure are suspended in the air, enabling the formwork to move and be fixed section by section along with the construction progress, thus forming a self-suspending formwork system. Its main function is to be unrestricted by the height and shape of the formwork, and to be able to flexibly adjust the position and angle according to construction needs to adapt to the construction requirements of different building structures. Existing suspension formwork devices are mostly fixed and used at the beam body through clamping members. However, the suspension formwork under this fixing method can only lift objects of a certain weight, and the clamping members are generally fixed by tightening multiple screws. When lifting too many or too heavy materials, there is a risk of the clamping members falling off. Summary of the Invention

[0003] The present invention provides a self-suspending formwork device for concrete beams, which overcomes the deficiencies described in the background art.

[0004] The technical solution adopted by the present invention to solve its technical problems is: A self-suspending formwork device for concrete beams, including a suspension member installed on the crossbeam body. The crossbeam body has a T-shaped structure. It is characterized in that the suspension member includes a fixed plate body, a hoisting mechanism, and a fixing mechanism. The fixed plate bodies are symmetrically arranged on the left and right sides of the crossbeam body. The hoisting mechanism is clamped between the two fixed plate bodies, and the outer sides of the two fixed plate bodies are both fixed through the fixing mechanism. The fixing mechanism includes a telescopic column, a negative pressure suction cup, and an air compressor. The negative pressure suction cup is installed in the fixed plate body and abuts against the surface of the crossbeam body. The telescopic column is obliquely fixed on the upper part of the outer side of the fixed plate body, and the end of the telescopic column abuts against the surface of the crossbeam body. The negative pressure suction cup is connected to the air compressor, and the air compressor is connected to the telescopic column through a gas storage airbag to extract air from the negative pressure suction cup by the air compressor to create negative pressure. Specifically, the negative pressure suction cup is installed in the fixed plate body and closely abuts against the surface of the crossbeam body. By extracting the air in the negative pressure suction cup by the air compressor, a strong negative pressure adsorption force is formed, enabling the fixed plate body to be firmly adsorbed on the surface of the crossbeam body. This adsorption force can not only provide a stable fixing effect but also, to a certain extent, disperse the force transmitted to the fixed plate body during the hoisting process, thereby enhancing the stability of the entire device.

[0005] The telescopic column includes a resisting rod, a first threaded pipe, and a second threaded pipe. The first threaded pipe is sleeved outside the resisting rod. A first sliding groove is provided inside the first threaded pipe, and the resisting rod is embedded in the first sliding groove. The first threaded pipe and the second threaded pipe are in threaded connection. A chamber is formed between the resisting rod and the second threaded pipe. An airbag is provided in this chamber. The airbag is respectively connected to an air compressor and the chamber through a bifurcated pipe. The second threaded pipe is fixed on the surface of the fixed plate body through a rotating shaft, so as to fix the fixed plate body by extending the resisting rod outward and pressing it against the surface of the crossbeam body. Further, the crossbeam body is composed of an upper member and a lower member. A first wire groove is provided on the surface of the upper member, and a second wire groove is provided on the surface of the lower member. The first wire groove and the second wire groove are arranged vertically. An embedding part is provided on one side of the fixed plate body facing the crossbeam body. The embedding part abuts against the surface of the second wire groove. The end of the resisting rod abuts against the surface of the first wire groove through a resisting block.

[0006] In a preferred technical solution, the airbag is fixed to the end of the resisting rod through fixing pieces provided on both sides. The bifurcated pipe extends through the rotating shaft at the bottom of the second threaded pipe and is connected to the airbag. When the resisting rod abuts against the surface of the crossbeam body and the second threaded pipe is rotated, the first threaded pipe extends outward.

[0007] In a preferred technical solution, a rubber suction cup is provided inside the negative pressure suction cup. The rubber suction cup protrudes from the surface of the negative pressure suction cup, and the rubber suction cup is connected to the air compressor through an air extraction pipe. The rubber suction cup is in a dish-shaped structure, and a plurality of air holes are provided on the lower side of the rubber suction cup. When the air compressor works, air is extracted through all the air holes, and negative pressure is created inside the rubber suction cup, so that the negative pressure suction cup adsorbs on the surface of the crossbeam body.

[0008] In a preferred technical solution, the symmetrically arranged fixed plate bodies form a U-shaped structure and are buckled on the lower part of the crossbeam body. The lower ends of the two fixed plate bodies both extend downward toward the middle of the crossbeam body. A second sliding groove is formed between the two fixed plate bodies. The hoisting mechanism is installed in this second sliding groove, and the surfaces of the two fixed plate bodies near the upper part of this second sliding groove are in a flat structure. The hoisting mechanism abuts against this flat structure.

[0009] In a preferred technical solution, third sliding grooves are provided on the adjacent surfaces of the two fixed plate bodies. A first raised part and a second raised part are respectively provided on the upper and middle surfaces of the mounting plate. The first raised part abuts against the surface of the second sliding groove, and the second raised part abuts against the surface of the third sliding groove.

[0010] In a preferred technical solution, the hoisting mechanism includes a mounting plate, a first motor, and a winding motor installed on the mounting plate. A plurality of tooth grooves are arranged equidistantly on the outside of the fixed plate body. A gear meshing with the tooth grooves is provided on the output shaft of the first motor, so as to drive the gear to rotate through the first motor and make the mounting plate slide on the fixed plate body.

[0011] Compared with the prior art, this technical solution has the following advantages: In the present invention, the telescopic column can not only adjust the length of the abutting rod by mechanically adjusting the rotating screw pipe 1 and screw pipe 2 to meet different construction requirements, but also pump the air at the negative pressure suction cup by an air compressor, and use the expansion force of the airbag to push the abutting rod outwards to further enhance the fixing effect. This dual adjustment mechanism enables the fixing mechanism to always maintain stable fixing performance when facing templates and materials of different weights and sizes, effectively solving the problem that the clamping components in the prior art are prone to falling off.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] like Figures 1 to 8 As shown, the present invention proposes a self-suspended formwork device for a concrete beam, comprising a suspension member 1 installed on a beam body 100, the beam body 100 being a T-shaped structure, characterized in that the suspension member 1 comprises a fixed plate body 11, a hoisting mechanism 12 and a fixing mechanism 13, the fixed plate bodies 11 are symmetrically arranged on the left and right sides of the beam body 100, the hoisting mechanism 12 is clamped between the two fixed plate bodies 11, and the outer sides of the two fixed plate bodies 11 are fixed by the fixing mechanism 13; The fixing mechanism 13 includes a telescopic column 131, a negative pressure suction cup 132 and an air compressor 133. The negative pressure suction cup 132 is installed in the fixing plate 11 and abuts against the surface of the beam body 100. The telescopic column 131 is fixed to the upper outer part of the fixing plate 11 in an inclined manner. The end of the telescopic column 131 abuts against the surface of the beam body 100. The negative pressure suction cup 132 is connected to the air compressor 133, and the air compressor 133 is connected to the telescopic column 131 through an air storage bag 1331, so that air is extracted from the negative pressure suction cup 132 through the air compressor 133 to create negative pressure. The telescopic column 131 includes a push rod 1311, a threaded tube 1 1312 and a threaded tube 2 1313. The threaded tube 1 1312 is sleeved outside the push rod 1311. A slide groove 1 is provided inside the threaded tube 1312. The push rod 1311 is embedded in the slide groove 1. The threaded tube 1 1312 and the threaded tube 2 1313 are threadedly connected. A chamber is formed between the push rod 1311 and the threaded tube 2 1313. An air bag 1314 is provided in the chamber. The air bag 1314 is connected to the air compressor 133 and the chamber through a bifurcated tube 1315. The threaded tube 2 1313 is fixed to the surface of the fixed plate body 11 through a rotating shaft, so that the fixed plate body 11 is fixed after the push rod 1311 is extended outward and pushes against the surface of the beam body 100. As can be seen from the above, in the fixing mechanism 13 of the present invention, the design of the telescopic column 131 cleverly combines the two modes of mechanical adjustment and pneumatic control, thereby realizing flexible adjustment of the length and position of the support rod 1311, solving the problem mentioned in the background technology that the existing hanging template device is not firmly fixed and is easy to fall off when lifting heavy materials; First, the telescopic column 131 is composed of a resisting rod 1311, a first threaded pipe 1312, and a second threaded pipe 1313. The first threaded pipe 1312 is sleeved outside the resisting rod 1311. A first chute is provided inside the first threaded pipe 1312, and the resisting rod 1311 is embedded in the first chute, thereby realizing the sliding of the resisting rod 1311 inside the first threaded pipe 1312. A threaded connection is formed between the first threaded pipe 1312 and the second threaded pipe 1313. By rotating the first threaded pipe 1312 and the second threaded pipe 1313, the extending length of the resisting rod 1311 can be adjusted. This mechanical adjustment method enables the telescopic column 131 to adapt to crossbeam bodies 100 of different sizes and shapes, ensuring that the resisting rod 1311 can accurately abut against the surface of the crossbeam body 100, thereby providing stable support for the fixed plate body 11; Secondly, the telescopic column 131 further enhances its fixing effect through pneumatic control. An airbag 1314 is provided inside the cavity of the telescopic column 131, and the airbag 1314 is connected to an air compressor 133 through a bifurcated pipe 1315. When the air compressor 133 is started, on the one hand, negative pressure is created by extracting air through a negative pressure suction cup 132 to firmly adsorb the fixed plate body 11 on the surface of the crossbeam body 100; on the other hand, the air compressor 133 inflates the airbag 1314, causing the airbag 1314 to expand. The pressure generated by the expansion of the airbag 1314 will push the resisting rod 1311 to extend outwards, further enhancing the contact force between the resisting rod 1311 and the crossbeam body 100, thereby achieving a more stable fixing effect. And when the air compressor 133 is started, it will inflate the airbag 1314 through the bifurcated pipe 1315. The pressure generated by the expansion of the airbag 1314 will push the resisting rod 1311 to extend outwards, thereby enhancing the contact force between the resisting rod 1311 and the crossbeam body 100 and further improving the fixing effect. However, if there is too much air in the airbag 1314, it may cause the airbag to over-expand, and may even damage the airbag or affect the normal operation of the telescopic column 131. To avoid this situation, the other end of the bifurcated pipe 1315 is connected to the cavity of the telescopic column 131. Through this connection design, when the pressure in the airbag 1314 reaches a certain level, the excess air can flow into the cavity of the telescopic column 131 through the bifurcated pipe 1315. In this way, the pressure in the airbag 1314 is effectively regulated, avoiding potential problems caused by over-inflation. At the same time, the air flowing into the cavity will also increase the internal pressure of the telescopic column 131 to a certain extent, thereby further enhancing the stability of the resisting rod 1311. This ingenious connection mechanism not only ensures that the airbag 1314 is always within a safe pressure range during operation, but also realizes the optimized distribution of the internal pressure of the telescopic column 131. When the resisting rod 1311 extends outwards and abuts against the surface of the crossbeam body 100, the pressure in the airbag 1314 is balanced with the pressure in the cavity of the telescopic column 131, enabling the resisting rod 1311 to be more stably fixed on the crossbeam body 100.

[0023] By combining the above two methods, the telescopic column 131 can not only adjust the length of the abutting rod 1311 by mechanically adjusting the rotating threaded pipe one 1312 and the threaded pipe two 1313 to meet different construction requirements, but also extract the air at the negative pressure suction cup 132 by the air compressor 133, and use the expansion force of the airbag 1314 to push the abutting rod 1311 outwards to further enhance the fixing effect. This dual adjustment mechanism enables the fixing mechanism 13 to always maintain stable fixing performance when facing templates and materials of different weights and sizes, effectively solving the problem that the clamping components are prone to falling off in the prior art, and greatly improving the reliability and safety of the self-suspending formwork device for concrete beams.

[0024] Furthermore, the crossbeam body 100 is composed of an upper member and a lower member. A first wire groove 101 is provided on the surface of the upper member, and a second wire groove 102 is provided on the surface of the lower member. The first wire groove 101 and the second wire groove 102 are vertically arranged. An embedding part is provided on one side of the fixing plate body 11 facing the crossbeam body 100, and the embedding part abuts against the surface of the second wire groove 102. The end of the abutting rod 1311 abuts against the surface of the first wire groove 101 through an abutting block 1317.

[0025] Moreover, the airbag 1314 is fixed to the end of the abutting rod 1311 through fixing pieces 1316 provided on both sides. The bifurcated pipe 1315 extends through the rotating shaft at the bottom of the threaded pipe two 1313 and is connected to the airbag 1314. When the abutting rod 1311 abuts against the surface of the crossbeam body 100 and the threaded pipe two 1313 is rotated, the threaded pipe one 1312 extends outwards.

[0026] In addition, a rubber suction cup 1321 is provided inside the negative pressure suction cup 132. The rubber suction cup 1321 protrudes from the surface of the negative pressure suction cup 132, and the rubber suction cup 1321 is connected to the air compressor 133 through an air extraction pipe 1322. The rubber suction cup 1321 is in a dish-shaped structure, and a plurality of air holes are provided on the lower side of the rubber suction cup 1321. When the air compressor 133 works, air is extracted through all the air holes, and negative pressure is created inside the rubber suction cup 1321, so that the negative pressure suction cup 132 adsorbs to the surface of the crossbeam body 100.

[0027] Moreover, the symmetrically arranged fixed plate bodies 11 form a U-shaped structure that is buckled to the lower part of the crossbeam body 100. The lower ends of the two fixed plate bodies 11 both extend downward toward the middle lower part of the crossbeam body 100. A second chute is formed between the two fixed plate bodies 11. The hoisting mechanism 12 is installed in this second chute. And the surfaces of the two fixed plate bodies 11 near the upper part of this second chute are flat structures. The hoisting mechanism 12 abuts against this flat structure. It should be noted that the direction of gravity is always vertically downward. In the design of the U-shaped structure, the lower ends of the two fixed plate bodies 11 both extend downward toward the middle lower part of the crossbeam body 100, forming a posture similar to "hugging". This structure enables the fixed plate bodies 11 to closely fit on the lower surface of the crossbeam body 100 under the action of gravity. Due to the fact that the direction of the gravitational force is consistent with the fitting direction of the fixed plate bodies 11, the U-shaped structure can better utilize gravity to firmly fix the fixed plate bodies 11 on the crossbeam body 100; The design of the U-shaped structure also has a certain self-locking function. Under the action of gravity, the lower ends of the fixed plate bodies 11 will closely fit on the lower surface of the crossbeam body 100, forming a state similar to "jamming". This self-locking function can effectively prevent the fixed plate bodies 11 from loosening or falling off due to external forces during the hoisting process. Even when hoisting a heavier formwork, the U-shaped structure can, through the action of gravity, firmly fix the fixed plate bodies 11 on the crossbeam body 100, thereby ensuring the safety and reliability of the entire device.

[0028] Moreover, third chutes 112 are provided on the adjacent surfaces of the two fixed plate bodies 11. First and second protrusions are respectively provided on the upper and middle surfaces of the mounting plate 121. The first protrusion abuts against the surface of the second chute, while the second protrusion abuts against the surface of the third chute 112.

[0029] Furthermore, the hoisting mechanism 12 includes a mounting plate 121, a first motor 122 and a winding motor 123 installed on the mounting plate 121. A plurality of tooth grooves 111 are arranged equidistantly on the outer side of the fixed plate body 11. A gear 1221 meshing with the tooth grooves 111 is provided on the output shaft of the first motor 122 to drive the gear 1221 to rotate through the first motor 122, so that the mounting plate 121 slides on the fixed plate body 11; And as Figure 2 shown, a traction rope is wound around the winding motor 123. During daily use, a hook or a fixing device can be fixed to the end of this traction rope to achieve the function of clamping and hoisting materials. It should be noted that the first and second wire grooves on the crossbeam body 100 in the present invention are formed on-line, that is, the first and second wire grooves are formed when the crossbeam body 100 is poured. The purpose and function in the present invention are to fix the fixed plate 11 and provide a support point for it. After the project is completed, the first and second wire grooves can be used as the grooves necessary for embedding water pipes, circuit pipes and cables during the decoration process.

[0030] The above is only a preferred embodiment of the present invention, and thus the scope of implementation of the present invention cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present invention patent and the content of the specification should still fall within the scope covered by the present invention.
