Description

Technical Field

[0001] The present application relates to the technical field of building assembly, and in particular to an assembled steel structure building. Background Art

[0002] With the development of society and the advancement of science and technology, prefabricated steel structure buildings have gradually appeared in people's vision. Each supporting plate, beam plate, supporting plate, and stair plate are designed and produced in the factory, and then transported to the construction site and directly installed by assembly. This construction method can greatly shorten the construction time and the building quality can also be guaranteed.

[0003] In the production process of traditional steel structure buildings, after the main steel structure is completed, a crossbeam steel structure consisting of a formwork and a steel cage will be installed on the top of the steel structure, and concrete will be poured on the top. After the concrete solidifies, the formwork will be removed to form a complete horizontal floor. In order to avoid gaps between the formworks that may cause concrete overflow and cause waste, the precision of the formwork will be improved during the manufacturing process to improve its sealing performance during the assembly process. This type of prefabricated steel structure building is currently the most widely used, with simple structure, easy use and low cost.

[0004] Although the existing prefabricated steel structure buildings have many advantages as mentioned above, there are still certain limitations in actual use. In order to ensure that the formwork can be firmly connected to the steel cage, a lot of bolts are used for connection, which results in a lot of time spent on removing the bolts when the formwork is disassembled later. In addition, when too much concrete is poured, the formwork cannot bear the weight and bends, resulting in excessive gaps. It will also cause the bottom of the floor slab to bend, resulting in serious quality problems. In this regard, the present application document proposes a prefabricated steel structure building to solve the above-mentioned problems. Summary of the invention

[0007] Furthermore, a handle is provided on the back of the closing plate and the closing plate is arc-shaped as a whole. The closing plate cooperates with the observation hole to form a complete tubular structure with the pressure-bearing pipe as a whole.

[0008] Furthermore, the locking device includes a connecting plate I, and a locking plate is fixedly installed on the bottom of the connecting plate I near both ends by welding. The width of the locking plate is greater than the width of the limiting slide rail. When the locking plate slides down, it will lock the closing plate so that it cannot be removed. A handle is fixedly installed on the back of the connecting plate I by welding.

[0009] Further, the supporting device includes a coupling seat, both sides of the coupling seat are movably mounted on the rotating base by means of shaft hole cooperation, a sleeve is fixedly installed on the top of the coupling seat by means of welding, a telescopic tube is movably installed on the inside of the sleeve by means of telescopic cooperation, a top seat is fixedly installed on the top of the telescopic tube by means of welding, a connecting plate II is fixedly installed on the top of the top seat near the two sides by means of welding, a rotating support plate is movably mounted on the inner side of the connecting plate II by means of shaft hole cooperation, and an anti-slip pad is fixedly installed on the top of the rotating support plate by means of bolt connection.

[0010] Furthermore, the interior of the oil filling tank is filled with hydraulic oil, and the hydraulic oil simultaneously fills the interiors of the locking tube, the pressure-bearing device and the supporting device.

[0011] Furthermore, the sealing device includes a sealing plate, a connecting pipe is fixedly installed by welding at a position near the middle of the bottom of the sealing plate, the connecting pipe is connected to the inner cavity of the pressure pipe, and the top of the sealing plate contacts the bottom of the crossbeam steel structure and plays a supporting role.

[0012] This application has the following beneficial effects.

[0013] 1. The top of the sealing plate is in contact with the bottom of the beam steel structure and plays a supporting role, so as to prevent the top of the beam steel structure from being excessively bent or broken due to the large lateral span of the beam steel structure or the excessive weight of the concrete exceeding the limit load of the beam steel structure when pouring concrete, thereby improving the stability of the device during use. At the same time, since the beam steel structure adopts a modular setting, gaps will inevitably appear between the beam steel structures during the assembly process, causing part of the concrete to fall from the gap and cause waste. After using the equipment involved in this application document, the top of the sealing plate is in contact with the connecting part between the beam steel structure. After pouring concrete, the bottom of the beam steel structure fits with the top of the sealing plate under the action of the dead weight of the concrete to achieve a sealing effect, thereby avoiding the problem of concrete falling from the gap between the beam steel structures and improving the reliability of the device. In addition, it also makes it no longer necessary to have too high requirements on the shape accuracy of the beam steel structure during the production of the beam steel structure, which can reduce the cost of the beam steel structure production process and improve the practicality of the device.

[0014] 2. Since the device can support the crossbeam steel structure, the number of bolts used to connect the crossbeam steel structure formwork and the steel cage can be reduced. This means that when the formwork of the crossbeam steel structure needs to be disassembled after the concrete solidifies, it is no longer necessary to spend a lot of time disassembling the bolts. In traditional equipment, in order to ensure a firm connection between the steel cage and the formwork, a large number of bolts are used to fix them. The device involved in this application document avoids this problem well, thereby improving the convenience of using the device.

[0015] 3. The pressure-bearing pipe is movably sleeved inside the locking pipe, so that the operator can adjust the extension length of the pressure-bearing pipe according to the actual working conditions, thereby ensuring that the device can stably support the crossbeam steel structure under working conditions of different heights, thereby improving the scope of application of the device. At the same time, when the pressure-bearing pipe is extended to an appropriate height, the locking screw can be rotated and screwed into the thread to make it contact with the outer surface of the pressure-bearing pipe, and the pressure-bearing pipe can be locked, so that the pressure-bearing pipe is in a fixed state, ensuring that it will not retract during the fixing process, thereby improving the stability of the device during use.

[0016] 4. A connecting pipe is fixedly installed by welding at the bottom of the sealing plate near the middle. The connecting pipe is connected to the inner cavity of the pressure-bearing pipe, so that during the pouring of concrete, part of the concrete will enter the inside of the connecting pipe through the gap reserved between the crossbeam steel structures, and then enter the inside of the pressure-bearing pipe. At this time, the dead weight of the concrete will act on the top of the pressure-bearing plate, driving the pressure-bearing plate to move in the vertical downward direction. Since the inside of the oil filling tank is filled with hydraulic oil, and the hydraulic oil simultaneously fills the inside of the locking tube, the pressure-bearing device and the supporting device, the internal hydraulic oil pressure is increased. Under the action of this pressure, the telescopic tube extends from the inside of the casing, thereby The supporting effect of the rotating support plate and the anti-skid pad on the beam steel structure is improved, and as the amount of concrete pouring increases, the thickness of the concrete continues to increase, the moving distance of the pressure plate continues to increase, the hydraulic oil pressure inside the locking tube, the pressure device and the support device continues to increase, and the supporting effect of the rotating support plate and the anti-skid pad on the beam steel structure is also continuously improved, so that the greater the amount of concrete poured on the top of the beam steel structure, the greater the support strength of the support device on the beam steel structure, thereby ensuring that the beam steel structure will not bend during the pouring process, avoiding the problem of bending of the beam after pouring, and further improving the practicality of the device.

[0017] 5. A closing plate is installed in the observation hole so that after the casting is completed, the operator can directly observe the state of the concrete inside the pressure pipe by removing the closing plate. When the concrete entering the pressure pipe is completely solidified, it can be directly judged that the concrete above the sealing plate has completed solidification, and the formwork and sealing device of the beam steel structure can be removed, thereby avoiding the problem of concrete collapse caused by dismantling the formwork and sealing device of the beam steel structure before the concrete is completely solidified, thereby improving the safety performance of the device. In addition, when pouring concrete, the locking device can be moved down. At this time, the width of the locking plate is greater than the width of the limit slide rail. When the locking plate slides down, the closing plate will be locked so that it cannot be removed, thereby achieving the locking effect of the locking plate on the limit slide rail, thereby avoiding the problem of concrete overflow caused by the detachment of the limit slide rail due to excessive pressure during concrete pouring, thereby further improving the reliability of the device during use.

[0018] 6. After the use of the device is completed, the hydraulic oil in the oil tank can be released. At this time, the hydraulic oil pressure inside the device is reduced, causing the telescopic tube to retract directly, so that the anti-slip pad is immediately separated from the bottom of the beam steel structure. At the same time, the closing plate can be pulled down by manual dragging to separate the pressure-bearing pipe from the sealing device, and then the sealing device can be separated from the concrete surface, so that the device can be quickly disassembled, further improving the practicality of the device.

The oil guide pipe 10 is respectively communicated with the oil filling box 1 and the inner cavity of the supporting device 9. Since the device can support the crossbeam steel structure 2, the number of bolts used to connect the template of the crossbeam steel structure 2 and the steel cage can be reduced. This makes it unnecessary to spend a lot of time to remove the bolts when the template of the crossbeam steel structure 2 needs to be disassembled after the concrete solidifies. In traditional equipment, in order to ensure a firm connection between the steel cage and the template, a large number of bolts are used to fix them. The device involved in the present application document avoids this problem well, thereby improving the convenience of using the device.

[0036] See also Figure 1-Figure 7The pressure-bearing device 6 includes a pressure-bearing tube 61, which is movably sleeved inside the locking tube 3. A limit block 62 is integrally casted on the outer surface of the pressure-bearing tube 61 near the bottom. The limit block 62 cooperates with the limit strip 4. The pressure-bearing tube 61 is movably sleeved inside the locking tube 3, so that the operator can adjust the extension length of the pressure-bearing tube 61 according to the actual working conditions, thereby ensuring that the device can stably support the crossbeam steel structure 2 under working conditions of different heights, thereby improving the scope of application of the device. At the same time, when the pressure-bearing tube 61 is extended to an appropriate height, the locking screw 5 can be rotated and the thread can be screwed in to make it contact with the outer surface of the pressure-bearing tube 61, and the pressure-bearing tube 61 can be locked, so that the pressure-bearing tube 61 is in a fixed state, ensuring that it is in the process of being fixed. There will be no retraction problem, which improves the stability of the device during use. An observation hole 63 is drilled on the outer surface of the pressure-bearing tube 61 near the top, and a closing plate 64 is installed inside the observation hole 63. A limiting slide rail 65 is fixedly installed on the outer surface of the pressure-bearing tube 61 above the observation hole 63 by welding, and a locking device 66 is movably installed inside the limiting slide rail 65 by sliding cooperation. A spring seat 67 is fixedly installed on the inner part of the pressure-bearing tube 61 below the observation hole 63 by welding, and a compression spring 68 is fixedly installed on the top of the spring seat 67 by snap-fitting. A pressure plate 69 is fixedly installed on the top of the compression spring 68 by snap-fitting, and the contact surface between the pressure plate 69 and the inner wall of the pressure-bearing tube 61 is sealed.

[0037] See also Figure 5-Figure 9 A handle is provided on the back of the closing plate 64 and the closing plate 64 is arc-shaped as a whole. The closing plate 64 cooperates with the observation hole 63 to form a complete tubular structure with the pressure-bearing pipe 61 as a whole.

[0038] See also Figure 1-Figure 9The locking device 66 includes a connecting plate Ⅰ661, and a locking plate 662 is fixedly installed at the bottom of the connecting plate Ⅰ661 near the two ends by welding. The width of the locking plate 662 is greater than the width of the limiting slide rail 65. When the locking plate 662 slides down, it will lock the closing plate 64 so that it cannot be removed. A handle 663 is fixedly installed on the back of the connecting plate Ⅰ661 by welding. The closing plate 64 is installed in cooperation with the inside of the observation hole 63, so that after the casting is completed, the operator can directly observe the state of the concrete inside the pressure pipe 61 by removing the closing plate 64. When the concrete entering the pressure pipe 61 is completely solidified, it can be directly judged that the concrete above the sealing plate 71 has completed solidification. , the formwork and the sealing device 7 of the beam steel structure 2 can be disassembled, thereby avoiding the problem of concrete collapse caused by disassembling the formwork and the sealing device 7 of the beam steel structure 2 before the concrete is completely solidified, thereby improving the safety performance of the device. In addition, when pouring concrete, the locking device 66 can be moved down. At this time, the width of the locking plate 662 is greater than the width of the limiting slide rail 65. When the locking plate 662 slides down, it will lock the closing plate 64 so that it cannot be disassembled, thereby achieving the locking effect of the locking plate 662 on the limiting slide rail 65, thereby avoiding the problem of concrete overflow caused by the detachment of the limiting slide rail 65 due to excessive pressure during concrete pouring, thereby further improving the reliability of the device during use.

[0039] See also Figure 1-Figure 12The supporting device 9 includes a coupling seat 91, and the two sides of the coupling seat 91 are movably sleeved with the rotating base 8 by means of shaft hole matching. The top of the coupling seat 91 is fixedly installed with a sleeve 92 by welding, and the inside of the sleeve 92 is movably installed with a telescopic tube 93 by means of telescopic matching. When the device is used, the hydraulic oil in the oil filling tank 1 can be released. At this time, the hydraulic oil pressure inside the device is reduced, so that the telescopic tube 93 is directly retracted, so that the anti-skid pad 97 is immediately separated from the bottom of the crossbeam steel structure 2. At the same time, the closing plate 64 can be pulled down by manual dragging to separate the pressure-bearing tube 61 from the sealing device 7. , then the sealing device 7 is separated from the concrete surface, so that the device can be quickly disassembled, which further improves the practicality of the device. The top of the telescopic tube 93 is fixedly installed with a top seat 94 by welding, and the top of the top seat 94 is fixedly installed with a connecting plate II 95 by welding near the two sides. The inner side of the connecting plate II 95 is movably sleeved with a rotating support plate 96 by means of shaft hole matching. The top of the rotating support plate 96 is fixedly installed with an anti-skid pad 97 by bolt connection. The bottom of the sealing plate 71 is fixedly installed with a connecting pipe 72 by welding near the middle position. The connecting pipe 72 and the bearing The inner cavities of the pressure pipe 61 are connected, so that during the pouring of concrete, part of the concrete will enter the interior of the connecting pipe 72 through the gap reserved between the crossbeam steel structure 2, and then enter the interior of the pressure pipe 61. At this time, the dead weight of the concrete will act on the top of the pressure plate 69, driving the pressure plate 69 to move in the vertical downward direction. Since the interior of the oil filling tank 1 is filled with hydraulic oil, and the hydraulic oil simultaneously fills the interior of the locking tube 3, the pressure-bearing device 6 and the supporting device 9, the internal hydraulic oil pressure is increased. Under the action of this pressure, the telescopic tube 93 extends from the interior of the sleeve 92, thereby increasing the rotation of the support plate 96 and the anti-skid pad 97 on the crossbeam steel. The supporting effect of the structure 2 is improved, and as the amount of concrete poured increases, the thickness of the concrete continues to increase, the moving distance of the pressure plate 69 continues to increase, the hydraulic oil pressure inside the locking tube 3, the pressure device 6 and the support device 9 also continues to increase, and the supporting effect of the rotating support plate 96 and the anti-slip pad 97 on the beam steel structure 2 is also continuously improved, so that the greater the amount of concrete poured on the top of the beam steel structure 2, the greater the support strength of the support device 9 on the beam steel structure 2, thereby ensuring that the beam steel structure 2 will not bend during the pouring process, avoiding the problem of bending of the beam after pouring, and further improving the practicality of the device.

[0040] See also Figure 1-Figure 4 The interior of the oil filling tank 1 is filled with hydraulic oil, and the hydraulic oil also fills the interior of the locking tube 3, the pressure-bearing device 6 and the supporting device 9.

[0041] See also Figure 1-Figure 9The sealing device 7 includes a sealing plate 71. A connecting pipe 72 is fixedly installed at a position near the middle of the bottom of the sealing plate 71 by welding. The connecting pipe 72 is connected to the inner cavity of the pressure-bearing pipe 61. The top of the sealing plate 71 contacts the bottom of the beam steel structure 2 and plays a supporting role. Since the beam steel structure 2 adopts a modular setting, gaps will inevitably appear between the beam steel structures 2 during the assembly process, causing part of the concrete to fall through the gaps and cause waste. After using the equipment involved in this application document, the top of the sealing plate 71 contacts the connecting part between the beam steel structures 2. After pouring the concrete, the bottom of the beam steel structure 2 automatically fits with the top of the sealing plate 71 under the action of the deadweight of the concrete, thereby achieving The sealing effect is achieved, thereby avoiding the problem of concrete falling from the gap between the beam steel structures 2, improving the reliability of the device, and also making it no longer necessary to have too high requirements on the shape accuracy of the beam steel structure 2 during the production of the beam steel structure 2, which can reduce the cost of the production process of the beam steel structure 2 and improve the practicality of the device. The top of the sealing plate 71 contacts the bottom of the beam steel structure 2 and plays a supporting role, thereby preventing the top of the beam steel structure 2 from lacking support due to the excessive lateral span of the beam steel structure 2 when pouring concrete, or preventing excessive bending or breaking due to the excessive weight of the concrete exceeding the limit load of the beam steel structure 2, thereby improving the stability of the device during use.

[0042] The method of use of the present invention is as follows:

[0043] During use, the top of the sealing plate 71 contacts the bottom of the crossbeam steel structure 2 and plays a supporting role, thereby preventing the top of the crossbeam steel structure 2 from being lacking support due to the large lateral span of the crossbeam steel structure 2 during concrete pouring, or preventing excessive bending or breaking due to the excessive weight of the concrete exceeding the limit load of the crossbeam steel structure 2. Since the crossbeam steel structure 2 adopts a modular setting, gaps will inevitably appear between the crossbeam steel structures 2 during the assembly process. The top of the sealing plate 71 contacts the connecting part between the crossbeam steel structures 2. After the concrete is poured, the bottom of the crossbeam steel structure 2 automatically fits with the top of the sealing plate 71 under the action of the deadweight of the concrete to achieve a sealing effect. Since the device can be used for the crossbeam steel structure 2 The number of bolts used to connect the formwork of the crossbeam steel structure 2 and the steel cage can be reduced, which means that when the formwork of the crossbeam steel structure 2 needs to be disassembled after the concrete solidifies, it is no longer necessary to spend a lot of time disassembling the bolts. The operator can adjust the extension length of the pressure pipe 61 according to the actual working conditions, thereby ensuring that the device can stably support the crossbeam steel structure 2 under working conditions of different heights, thereby improving the scope of application of the device. At the same time, when the pressure pipe 61 is extended to an appropriate height, the locking screw 5 can be rotated and screwed into the screw thread to make it contact with the outer surface of the pressure pipe 61, and the pressure pipe 61 can be locked, so that the pressure pipe 61 is in a fixed state, and the connecting pipe 72 is connected to the inner cavity of the pressure pipe 61. The connection allows part of the concrete to enter the connecting pipe 72 through the gap reserved between the crossbeam steel structures 2 during the concrete pouring process, and then enter the pressure pipe 61. At this time, the deadweight of the concrete will act on the top of the pressure plate 69, driving the pressure plate 69 to move in the vertical downward direction. Since the interior of the oil filling tank 1 is filled with hydraulic oil, and the hydraulic oil simultaneously fills the interior of the locking tube 3, the pressure-bearing device 6 and the supporting device 9, the internal hydraulic oil pressure is increased. Under the action of this pressure, the telescopic tube 93 extends from the interior of the sleeve 92, thereby improving the supporting effect of the rotating support plate 96 and the anti-slip pad 97 on the crossbeam steel structure 2, and as the amount of concrete poured increases, the thickness of the concrete continues to increase, and the moving distance of the pressure plate 69 continues to increase. , the hydraulic oil pressure inside the locking tube 3, the pressure-bearing device 6 and the supporting device 9 is also continuously increased, and the supporting effect of the rotating supporting plate 96 and the anti-skid pad 97 on the beam steel structure 2 is also continuously improved, so that the greater the amount of concrete poured on the top of the beam steel structure 2, the greater the supporting force of the supporting device 9 on the beam steel structure 2, thereby ensuring that the beam steel structure 2 will not bend during the pouring process. The operator can directly observe the state of the concrete inside the pressure-bearing tube 61 by removing the closing plate 64. When the concrete entering the pressure-bearing tube 61 is completely solidified, it can be directly determined that the concrete above the sealing plate 71 has completed solidification, and the template of the beam steel structure 2 and the sealing device 7 can be disassembled. When pouring concrete,The locking device 66 can be moved downward. At this time, the width of the locking plate 662 is greater than the width of the limit slide rail 65. When the locking plate 662 slides down, it will lock the closing plate 64 so that it cannot be removed, thereby achieving the locking effect of the locking plate 662 on the limit slide rail 65. When the device is used, the hydraulic oil in the oil filling tank 1 can be released. At this time, the hydraulic oil pressure inside the device is reduced, so that the telescopic tube 93 directly retracts and the anti-skid pad 97 is immediately separated from the bottom of the beam steel structure 2. At the same time, the closing plate 64 can be pulled down by manual dragging to separate the pressure-bearing tube 61 from the sealing device 7, and then the sealing device 7 is separated from the concrete surface, so that the device can be quickly disassembled.
