Description

Technical Field

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

[0002] In the field of construction, high-rise and super-high-rise buildings continue to emerge, which puts higher requirements on the stability and bearing capacity of the structure. In some cases, traditional concrete structures are difficult to meet the needs of large spans and high loads, while steel structures, with their high strength, light weight, and prefabrication, have gradually become the preferred support structure for many large-scale projects.

[0003] When constructing steel structures, it is necessary to use a crane to lift the steel to the corresponding position. For example, the crane's hook is connected to the pre-set lifting point on the steel, and the hook is adjusted to be perpendicular to the center of gravity of the steel by adjusting the crane's boom and hook position. After confirming that everything is correct, slowly lift the steel, lift it to a certain height from the ground, and then stop lifting to check the balance of the steel and the working status of the crane. If everything is normal, continue lifting, lift the steel to the top of the designed position, and then slowly lower it so that the steel is accurately positioned on the lower structure. After the steel structure is in place, it needs to be operated by a crane to keep it in the corresponding position for a long time, and then use bolts, welding, etc. to connect adjacent steels.

[0004] From the above, it can be seen that in the process of assembling steel into steel structure, after each steel is lifted by the crane, the steel needs to be controlled to be stable in a certain position to achieve the connection between adjacent steels. It takes a long time to complete the above operation. Therefore, the assembly efficiency of the entire steel structure is low.

[0005] If the steel can be lifted to the corresponding position by the crane, and the steel and the crane are disconnected, the crane can be used to lift another steel. This operation reduces the time of using the crane for each steel, facilitates the overlapping construction of multiple steels, and speeds up the assembly of steel structures.

DETAILED DESCRIPTION

[0031] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0033] Example 1

[0034] like Figure 1 As shown, in order to reduce the time occupied by each I-beam 1, and to facilitate the crane to lift another I-beam 1 to the corresponding position when the I-beam 1 is connected to the adjacent I-beam 1, this embodiment provides a structure for supporting the I-beam 1 so that it is stably placed relative to the already installed I-beam 1. When the support structure provided by this embodiment is used, the support structure is installed on the I-beam 1 that has been stably installed. When the crane lifts the I-beam 1 to be installed and rises to the support structure, the end of the I-beam 1 to be installed is supported on the support structure. Therefore, under the action of the support structure, the I-beam 1 to be installed can be stably placed, which facilitates the connection of adjacent I-beams 1 by bolts or welding. In the process of the staff connecting the I-beam 1 to the adjacent I-beam 1, the crane lifts another I-beam 1 to be installed to the corresponding position, and stably supports the I-beam 1 under the action of the support structure. Repeating the above operations can reduce the installation time of the steel structure as a whole and improve the installation efficiency of the steel structure.

[0035] like Figure 1 , Figure 2As shown, specifically, the support structure includes a support plate 2, a support platform 3, a mounting mechanism 5, etc. The mounting mechanism 5 is fastened and sleeved on the vertical I-beam 1 that has been fixedly installed, and the support platform 3 is assembled and arranged above the mounting mechanism 5. At the same time, the support plate 2 is arranged on the support platform 3, and the height of the support plate 2 can be adjusted relative to the support platform 3. Therefore, when the crane lifts the I-beam 1 to be installed above the support plate 2, the end of the I-beam 1 is directly supported on the support plate 2, and the height of the support plate 2 can be adjusted according to demand, thereby adjusting the state of the I-beam 1, and providing support for stably connecting the I-beam 1 with the adjacent I-beam 1 by bolts or welding.

[0036] like Figure 3 As shown, in order to stably install the mounting mechanism 5 on the vertical I-beam 1, the mounting mechanism 5 includes a first clamping plate 52, a second clamping plate 53, two fastening screws 51, etc. The first clamping plate 52 and the second clamping plate 53 are both configured as a frame structure, and are arranged in parallel and distributed on both sides of the I-beam 1. Because the length of the first clamping plate 52 and the second clamping plate 53 is greater than the length and width of the I-beam 1, both ends of the first clamping plate 52 and the second clamping plate 53 are protruding from the I-beam 1. A threaded hole is provided on the end of the first clamping plate 52, and a through hole 54 is provided on the end of the second clamping plate 53, and the threaded hole and the through hole 54 are opposite, so the two fastening screws 51 are respectively passed through the through holes 54 at both ends of the second clamping plate 53, and the ends are threadedly inserted into the threaded holes of the first clamping plate 52. By rotating the fastening screw 51 , the first clamping plate 52 and the second clamping plate 53 are forced to approach each other, thereby pressing the vertical I-beam 1 . Under the action of the friction force therebetween, the first clamping plate 52 and the second clamping plate 53 are stably placed relative to the vertical I-beam 1 .

[0037] like Figure 4 As shown, since only the first clamp plate 52 and the second clamp plate 53 are provided in the mounting mechanism 5, if the pallet 2 is to be stably set on the mounting mechanism 5, the support platform 3 is required to provide a flat platform for the installation of the pallet 2, that is, under the action of the support platform 3, the pallet 2 can be installed just above the gap between the first clamp plate 52 and the second clamp plate 53.

[0038] like Figure 4 As shown, specifically, the support platform 3 includes two first plates 31 and two second plates 32. The two first plates 31 are arranged in parallel, and the two second plates 32 are also arranged in parallel. The length of the first plate 31 is smaller than the length of the second plate 32. Therefore, the first plate 31 is arranged between the two second plates 32, that is, the first plate 31 and the second plate 32 are spliced ​​to form a rectangular structure.

[0039] like Figure 5 , Figure 6As shown, in order to achieve stable and detachable connection between the adjacent first plate 31 and the second plate 32, a snap plate 313 is fixedly arranged at the end of the first plate 31, and a snap groove 323 is arranged on the upper side of the second plate 32. The snap groove 323 and the snap plate 313 are both arranged as T-shaped structures. Therefore, the snap plate 313 is installed in the snap groove 323, which limits the relative stable connection between the first plate 31 and the second plate 32, and at the same time provides convenience for disassembling the first plate 31 and the second plate 32 as required. In this case, the first plate 31 is located on the first clamping plate 52 and the second clamping plate 53, and the end of the second plate 32 is supported on the end of the first clamping plate 52 and the second clamping plate 53, so that the support platform 3 has a higher strength to withstand the force applied by the support plate 2. In addition, in the actual use process, the first plate 31 and the clamping plate facing each other up and down can be connected by bolts as required to enhance the stability of the support platform 3.

[0040] like Figure 3 , Figure 5 , Figure 6 , Fig. 9 As shown, in order to stably set the support plate 2 on the support platform 3, the limiting plates 25 are fixedly set at both ends below the support plate 2. A third limiting hole 312 is set on the first plate body 31, a first limiting hole 322 is set on the second plate body 32, and a second limiting hole 56 is set on the upper side of the first clamping plate 52 and the second clamping plate 53. The second limiting hole 56 is directly opposite to the third limiting hole 312. Therefore, the bottom of the limiting plate 25 is inserted into the second limiting hole 56 and the third limiting hole 312 at the same time. Under the action of the limiting plate 25, the clamping plate and the first plate body 31 are more stably connected, so that the support platform 3 is stably installed on the mounting mechanism 5. When the limiting plate 25 passes through the first limiting hole 322, the support plate 2 can be stably set above the second plate body 32. Because the limiting plate 25 is inserted into the limiting hole, it is convenient for the support plate 2 to rise and fall under the action of external force. Therefore, the height of the support plate 2 can be adjusted according to demand to provide support for stably supporting the I-beam 1 so that it is connected to the adjacent I-beam 1.

[0041] like Figure 5 , Figure 6 , Fig. 9 As shown, in order to adjust the height of the support plate 2 according to the needs, a threaded hole 22 and a round hole 21 are provided on the bottom surface of the support plate 2, a threaded rod 23 is threadedly provided at the threaded hole 22, and a column 24 is provided at the round hole 21. At the same time, a first slot 311 is provided on the first plate body 31, and a second slot 321 is provided on the second plate body 32. The bottoms of the threaded rod 23 and the column 24 are inserted into the slots. By rotating the threaded rod 23, the support plate 2 can be controlled to rise and fall relative to the first plate body 31 or the second plate body 32, thereby realizing the adjustment of the height of the support plate 2.

[0042] Example 2

[0043] like Figure 2 As shown, on the basis of Example 1, in order to stably install the support structure after the I-beam 1 to be installed is supported, a brake mechanism 4 is further provided on the inner side of the installation mechanism 5. There are four sets of brake mechanisms 4, and the four sets of brake mechanisms 4 are divided into two groups, and two sets of brake mechanisms 4 are provided in pairs in each group. The two sets of brake mechanisms 4 are respectively provided in the two grooves of the I-beam 1, and the ends of the brake mechanisms 4 are in contact with the side walls of the I-beam 1. Therefore, under the action of the brake mechanisms 4, the resistance of the support structure to move relative to the working steel 1 is increased. And when the support structure moves downward due to the gravity of the I-beam 1, the pressure applied by the brake mechanism 4 to the I-beam 1 increases, and the friction between them increases, thereby making the support structure stably placed relative to the vertical I-beam 1.

[0044] like Figure 7 , Figure 8 As shown, in order to achieve the above functions, the brake mechanism 4 includes a brake plate 42, a common plate 45 and a diagonal support plate 44. The common plate 45 and the brake plate 42 are arranged in parallel, and the diagonal support plate 44 is hingedly arranged between the common plate 45 and the brake plate 42. The brake plate 42 contacts the side wall of the I-beam, and the end tube 43 is fixedly arranged on the common plate 45. A driving plate 41 is arranged on the side of each group of brake mechanisms 4. The two ends of the driving plate 41 are respectively penetrated through the connecting holes 55 on the first clamping plate 52 and the second clamping plate 53, and the driving plate 41 is arranged through the end tube 43. When the installation mechanism 5 and the brake mechanism 4 are installed, the common plate 45 can be pulled down under the action of the installation mechanism 5, so that the two brake plates 42 in the same group have a tendency to move away from each other, that is, the brake plate 42 is arranged in contact with the side wall of the I-beam 1. At this time, the brake mechanism 4 is stably installed relative to the I-beam 1. When the installation mechanism 5 moves downward slightly under the action of external force, the common plate 45 is controlled to move downward under the action of the driving plate 41, increasing the force applied by the brake plate 42 to the I-beam 1, thereby increasing the friction between them and enhancing the stable installation of the support structure and the vertical I-beam 1.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
