Description

Technical Field

[0001] The invention relates to the technical field of steel structure support, in particular to a steel structure support column of a building template. Background Art

[0002] Building formwork is a temporary supporting structure, which is made according to the design requirements to shape the concrete structure and components into the specified position and geometric dimensions, maintain its correct position, and bear the deadweight of the building formwork and the external loads acting on it. The traditional construction method is to directly set up the scaffolding and then install the wooden formwork. This method has a large workload and many limitations in application. In addition, it is impossible to conveniently raise and lower the height and adjust the length as needed, which ultimately greatly affects the operation of the construction process.

[0003] To this end, a Chinese patent with publication number "CN211850854U" announced "a support device for a steel structure building formwork", whose main structure includes a support base, threaded columns are provided on both sides of the upper end of the support base, the lower ends of the threaded columns extend into the support base, and a transmission belt is rotatably connected between the lower ends of the two groups of threaded columns. A servo motor is provided in the support base, and the power shaft end of the servo motor is fixedly connected to the lower end of a group of threaded columns. The upper sides of the two groups of threaded columns are threadedly connected to both ends of the workbench, and by arranging a metal drill rod, it can be plugged into the ground to enhance the stability of the device and prevent the device from displacement. In addition, by arranging threaded columns and electric telescopic rods, the angle and height of the support plate can be conveniently adjusted, so as to facilitate the completion of support at various angles and enhance the scope of application of the device.

[0004] Through the above technical solution, it can be known that: when the supporting device of the above-mentioned steel structure building formwork is actually working, since it is located at the construction site, the device will constantly withstand the displacement of components caused by the vibration generated during the construction process, and the threaded structure is most likely to rotate relative to each other after being subjected to mechanical vibration, causing the threaded structure to loosen at the bite position, thereby causing the supporting stability of the device to deteriorate during support, posing a major safety hazard.

When the longitudinal threaded sleeve 51 is rotated, due to the action of the No. 1 threaded structure 57 and the longitudinal limiting rod 59, the longitudinal threaded rod 56 can be moved in multiple directions. The longitudinal threaded rod 56 can be controlled to move upward or downward by controlling the rotation direction of the longitudinal threaded sleeve 51. Initially, the longitudinal threaded sleeve 51 is rotated to make the longitudinal threaded rod 56 move upward and drive the abutment head 4 to move upward until the abutment head 4 abuts against the bottom of the building formwork and plays a supporting role. Then, the rotation of the longitudinal threaded sleeve 51 is stopped. On the contrary, when disassembly is required, the longitudinal threaded sleeve 51 is rotated in the opposite direction to reset the longitudinal threaded rod 56, thereby achieving a height-adjustable supporting effect.

[0033] For the specific structure of the threaded support mechanism 5, please refer to Figure 3 and Figure 4, including a longitudinally arranged longitudinal threaded sleeve 51, the bottom end of the longitudinal threaded sleeve 51 is provided with a No. 2 fixing plate 55 of an integral structure therewith, a hexagonal rotating table 52 of an integral structure therewith is provided in the middle of the circumferential surface of the longitudinal threaded sleeve 51, a longitudinal threaded hole 53 with an open top is provided inside the longitudinal threaded sleeve 51, a No. 1 shaft body through hole 54 connecting the space below it and the bottom end of the longitudinal threaded hole 53 is provided at the bottom center of the longitudinal threaded sleeve 51, the longitudinal threaded sleeve 51 is provided with a longitudinal threaded rod 56 installed inside the longitudinal threaded hole 53 through a No. 1 threaded structure 57, specifically, the No. 1 threaded structure 57 includes an internal threaded structure provided at the inner wall of the circumference of the longitudinal threaded hole 53 and an external threaded structure provided in the rod body of the longitudinal threaded rod 56, and the internal threaded structure and the external threaded structure match, the longitudinal threaded rod 56 A No. 1 fixing plate 510 which is an integral structure with the No. 1 fixing plate 510 and is fixedly mounted on the bottom end of the abutment head 4 is provided at the top thereof, a polygonal limiting hole 58 whose bottom end is open is provided inside the longitudinal threaded rod 56, a longitudinal limiting rod 59 is arranged inside the polygonal limiting hole 58 of the longitudinal threaded rod 56, and in order to prevent the component from self-rotating, it is necessary to make the structural shape of the longitudinal cross section of the polygonal limiting hole 58 consistent with the structural shape of the longitudinal cross section of the longitudinal limiting rod 59, both of which are polygonal structures, the structural dimensions of the longitudinal cross section of the polygonal limiting hole 58 match the structural dimensions of the longitudinal cross section of the longitudinal limiting rod 59, and the structural dimensions of the longitudinal cross section of the longitudinal limiting rod 59 are smaller than the caliber of the No. 1 shaft through hole 54, the bottom end rod body of the longitudinal limiting rod 59 passes through the No. 1 shaft through hole 54, and the bottom end rod body is fixedly mounted inside the No. 1 component fixing groove 3.

[0034] In order to achieve a wrap-around positioning effect on the longitudinal threaded sleeve 51 to prevent the components from loosening, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6, it is necessary to set up a hydraulic wrapping mechanism 6, which is provided with a central rotating column 63 installed in the No. 1 component mounting groove 2 through a bearing and rotating with the longitudinal threaded sleeve 51, an outer annular shell 61 located outside the central rotating column 63 and fixedly installed above the bottom support base 1, and an airbag sheet 69 embedded in the outer annular shell 61 and capable of wrapping around the outer circumferential surface of the central rotating column 63 after being subjected to liquid pressure. When the support work is adjusted, it is used in conjunction with a hydraulic device, so that the hydraulic device fills a certain pressure of liquid into the annular liquid flow cavity 67 through the liquid docking channel 610. Under the action of the flow of the liquid, a force is generated on the outer surface of the airbag sheet 69. , causing the airbag sheet 69 to bend and expand inward, and finally causing the inner surface of the airbag sheet 69 to come into contact with the periphery of the strip anti-skid rib 66 in a wrapped form, so that the central rotating column 63 is in a clamped state, and the vibration will not cause the central rotating column 63 to rotate, thereby preventing the longitudinal threaded sleeve 51 from loosening during operation, thereby achieving a wrapped positioning effect on the longitudinal threaded sleeve 51, thereby preventing the occurrence of loose components. When the supporting work is completed, the liquid inside the equipment is released through the hydraulic valve, and the airbag sheet 69 is reset due to its own elasticity, thereby releasing the force on the central rotating column 63, facilitating the reverse rotation of the longitudinal threaded sleeve 51.

[0035] For the specific structure of the hydraulic wrapping mechanism 6, please refer to Figure 5 and Figure 6, including an outer annular shell 61 and a central rotating column 63, the top of the central rotating column 63 is provided with a third fixing plate 64 which is an integral structure with it and fixedly mounted on the bottom end of the second fixing plate 55, the central rotating column 63 is installed in the interior of the No. 1 component mounting groove 2 through a bearing on the outer circumferential surface near its bottom end, the center of the central rotating column 63 is provided with a No. 2 shaft body through hole 65 for sleeve-mounting the longitudinal limit rod 59, in order not to hinder the rotation of the component, it is necessary to make the diameter of the No. 2 shaft body through hole 65 larger than the structural dimension of the longitudinal cross section of the longitudinal limit rod 59, the middle part of the circumferential side surface of the central rotating column 63 is provided with a strip anti-skid rib 66 which is an integral structure with it, the center of the outer annular shell 61 is provided with a central sleeve hole 612 which is sleeved on the periphery of the central rotating column 63, and the bottom end of the outer annular shell 61 is provided with a central sleeve hole 612 which is an integral structure with it The outer annular shell 61 is provided with a plurality of arc-shaped liquid flow chambers 68 in an annular array state, and an airbag sheet 69 is embedded in the inner port of each arc-shaped liquid flow chamber 68 in an edge-sealed manner. The airbag sheet 69 is a sheet structure with elastic extension function and made of wear-resistant material. The outer annular shell 61 is provided with an annular liquid flow chamber 67 connecting the outer ports of each arc-shaped liquid flow chamber 68, and the circumferential surface of the outer annular shell 61 is provided with a No. 1 liquid flow hole 611 connecting the external space and the annular liquid flow chamber 67. The circumferential surface of the outer annular shell 61 is provided with a liquid docking channel 610 connecting the external space and the annular liquid flow chamber 67, and a liquid valve is installed inside the liquid docking channel 610.

[0036] To achieve control over the strength of the wrap, see Figure 1 , Figure 2 , Figure 7 and Figure 8, it is necessary to set up an elastic pressure control mechanism 7, which is provided with a No. 1 valve plate 78 that can block the end of the No. 1 liquid flow hole 611 and open the No. 1 liquid flow hole 611 when moving, a coil spring 713 that produces an elastic damping effect on the No. 1 valve plate 78, and a No. 2 valve plate 710 that can change the elastic strength of the coil spring 713. According to the strength of the construction site, the control ability of the wrapping force can be adjusted. In a slightly vibrating site, by rotating the rotating plate 716, the horizontal threaded rod 714 drives the No. 2 valve plate 710 away from the No. 1 valve plate 78, increasing the lateral distance between the No. 2 valve plate 710 and the No. 1 valve plate 78, thereby increasing the compression stroke of the coil spring 713 to reduce the elastic force of the coil spring 713 on the No. 1 valve plate 78. On the contrary, when In high-intensity vibration environments, the elastic force of the coil spring 713 on the No. 1 valve plate 78 is increased, and then, the hydraulic equipment is used to fill the liquid into the annular liquid flow chamber 67 through the liquid docking channel 610. Under the flow of the liquid, the liquid will exert a force on the No. 1 valve plate 78 through the No. 2 liquid flow hole 74. When the liquid pressure is greater than the above-mentioned elastic force, the No. 1 valve plate 78 will move. At this time, the liquid will flow outward through the gap near the No. 1 valve plate 78, the No. 1 liquid flow groove 711, the No. 2 liquid flow groove 712 and the liquid reflux channel 75. When the liquid is seen flowing out, the hydraulic equipment is closed in time, so that the wrapping force of the airbag sheet 69 on the central rotating column 63 reaches a predetermined value, thereby exerting a wrapping and clamping force of corresponding strength.

[0037] For the specific structure of the elastic pressure control mechanism 7, please refer to Figure 7 and Figure 8, including a horizontal hollow shell 71, one end surface of the horizontal hollow shell 71 is provided with a fourth fixing plate 72 which is integrally formed with the horizontal hollow shell 71 and fixedly mounted on the outer circumferential surface of the outer annular shell 61, a horizontal component movable cavity 73 is provided inside the horizontal hollow shell 71, one end of the horizontal hollow shell 71 is provided with a transverse threaded hole 76 which connects the external space and the horizontal component movable cavity 73, the other end of the horizontal hollow shell 71 is provided with a second liquid flow hole 74 which connects the horizontal component movable cavity 73 and the first liquid flow hole 611, the circumferential surface of the horizontal hollow shell 71 is provided with a second liquid flow hole 74 which is integrally formed with the horizontal hollow shell 71 and connects the horizontal component movable cavity 73 near the transverse threaded hole 76 The horizontal hollow shell 71 is provided with a first valve plate 78 which can move axially along the horizontal component movable cavity 73 and is close to the second liquid flow hole 74, and the horizontal hollow shell 71 is provided with a second valve plate 710 which can move axially along the horizontal component movable cavity 73 and is close to the transverse threaded hole 76. The circumferential surface of the first valve plate 78 is provided with a first liquid flow groove 711 with an inner concave structure for horizontal flow of liquid, and the circumferential surface of the second valve plate 710 is provided with a second liquid flow groove 710 with an inner concave structure for horizontal flow of liquid. 12. The horizontal component movable cavity 73 is provided with a helical spring 713 in a compressed state between the No. 1 valve plate 78 and the No. 2 valve plate 710. The No. 1 valve plate 78 is embedded with an annular sealing ring 79 at the end surface facing the No. 2 liquid flow hole 74. The No. 2 valve plate 710 is provided with a rotatable inner rotating shaft 715 through a bearing at one end surface facing the transverse threaded hole 76. One end of the inner rotating shaft 715 is provided with a horizontal threaded rod 714 which is an integral structure with the horizontal threaded rod 714 and passes through the transverse threaded hole 76. The rod body of the horizontal threaded rod 714 and the transverse threaded hole 76 are connected by a No. 2 threaded structure 77. Specifically, the No. 2 threaded structure 77 includes An internal thread structure is arranged on the inner wall of the circumference of the transverse threaded hole 76 and an external thread structure is arranged in the rod body of the horizontal threaded rod 714, and the internal thread structure and the external thread structure match each other. The horizontal threaded rod 714 is equipped with a rotating plate 716 at one end located outside the horizontal hollow shell 71. In order to achieve the blocking and flow of the liquid, it is necessary to make one end of the annular closing ring 79 protrude outward relative to the mounting end surface of the No. 1 valve plate 78, and the inner ring structure radius of the annular closing ring 79 is larger than the structure radius of the No. 2 liquid flow hole 74, and the outer ring structure radius of the annular closing ring 79 is smaller than the distance between the No. 1 liquid flow groove 711 and the center line of the No. 1 valve plate 78.

[0038] The specific working principle of the present invention is that the bottom support base 1 contacts the ground or the bottom platform, and the contact head 4 needs to be located directly below the building template;

[0039] The longitudinal threaded sleeve 51 is rotated to make the longitudinal threaded rod 56 move upward and drive the abutment head 4 to move upward until the abutment head 4 abuts against the bottom of the building formwork and plays a supporting role, and then the rotation of the longitudinal threaded sleeve 51 is stopped;

[0040] It is used in conjunction with a hydraulic device, so that the hydraulic device fills a certain pressure of liquid into the annular liquid flow chamber 67 through the liquid docking channel 610. Under the action of the flow of the liquid, a force is generated on the outer surface of the airbag sheet 69, causing the airbag sheet 69 to bend and expand inward, and finally causing the inner surface of the airbag sheet 69 to contact the outer periphery of the strip anti-skid rib 66 in a wrapped form, so that the central rotating column 63 is in a clamped state, and vibration will not cause the central rotating column 63 to rotate, thereby preventing the longitudinal threaded sleeve 51 from being loosened during operation;

[0041] When disassembly is required, the liquid inside the device is released through the hydraulic valve, and the airbag sheet 69 is reset due to its own elasticity. The longitudinal threaded sleeve 51 is then rotated in the reverse direction to reset the longitudinal threaded rod 56, thereby achieving a height-adjustable support effect.
