[0027] The embodiment of the present application provides a steel structure installation platform, which can solve the problem in the related art that when constructing the steel beam superstructure, temporary facilities such as escalators and ladder cages are inconvenient to move, thereby affecting the construction efficiency.

[0028] See also Figure 1 As shown, a steel structure installation platform provided by an embodiment of the present application may include: a movable fixing component 1, the movable fixing component 1 is used to be installed on the steel beam 2, the movable fixing component 1 includes a clamping mechanism, the clamping mechanism includes a cross plate 11 and a clamping plate 12 connected to one end of the cross plate 11, the cross plate 11 and the clamping plate 12 are connected to form a placement space for the steel beam 2, and the cross plate 11 can fit partially with the steel beam 2 at this time; the movable fixing component 1 also includes a movable adjustment component 13, the movable adjustment component 13 is installed on a side of the cross plate 11 away from the clamping plate 12, and the movable adjustment component 13 includes an adjustment rod 131 installed perpendicular to the cross plate 11, and the adjustment rod 131 is away from the cross plate A fixing plate 132 is connected to one side of the transverse plate 11, and the fixing plate 132 and the transverse plate 11 are spaced apart along the extension direction of the adjusting rod 131, and the fixing plate 132, the adjusting rod 131 and the transverse plate 11 are connected to each other to form a clamping space; a working platform 3, the working platform 3 is fixed to the side of the transverse plate 11 away from the steel beam 2, the working platform 3 includes a supporting platform 31, and a heightening mechanism 32 clamped between the supporting platform 31 and the transverse plate 11, the staff can stand on the working platform 3 to carry out construction, the heightening mechanism 32 is configured to be heightened in the vertical direction, and the height of the heightening mechanism 32 in the vertical direction can be adjusted according to the height required by different construction sites.

[0029] The embodiment of the present application provides a movable fixing assembly 1, and the engaging mechanism in the movable fixing assembly 1 cooperates with the movable adjustment assembly 13, so that the height increasing mechanism 32 fixed to the horizontal plate 11 and the working platform 3 can be fixed or moved on the steel beam 2, see Figure 3As shown, in this embodiment, the steel beam 2 is H-shaped, and the clamping plate 12 is an "L"-shaped structure. The steel beam 2 placement space surrounded by the cross plate 11 and the clamping plate 12 is a U-shaped structure that matches the upper flange 21 of the H-shaped steel beam 2. The upper flange 21 can have a little gap in the steel beam 2 placement space. While ensuring that the upper flange 21 can be clamped, the cross plate 11 can also move in the upper flange 21 along the extension direction of the steel beam 2. In some other embodiments, the steel beam 2 placement space can also be other different shapes. The fixing plate 132, the adjusting rod 131 and the cross plate 11 are connected to each other to form a clamping space, and the clamping space is used to clamp the upper flange 21 on the other side of the H-shaped steel beam 2. The cross plate 11 and the fixing plate 132 are respectively located on the upper side and the lower side of the upper flange 21. At this time, the cross plate 11 and the clamping plate 12 are clamped on the steel beam 2 at one end of the cross plate 11 through the steel beam 2 placement space, and the cross plate 11 is matched with the cross plate 11 at the other end of the cross plate 11 through the adjusting rod 131 and the fixing plate 132. When the distance between the cross plate 11 and the fixing plate 132 on the upper and lower sides of the upper flange 21 is greater than the thickness of the upper flange 21 in the vertical direction, the cross plate 11 can be moved; when the distance between the fixing plate 132 and the cross plate 11 is equal to the thickness of the upper flange 21 in the vertical direction, the cross plate 11 is fixed to the upper flange 21. This arrangement allows the workers to complete the construction by standing on the working platform 3 when constructing the upper structures above the steel beam 2. When it is necessary to move to other positions for construction, the adjusting rod 131 in the movable adjustment component 13 is adjusted to change the size of the clamping space between the cross plate 11 and the fixing plate 132, thereby enabling the steel structure installation platform to be moved as a whole. This solves the problem in the related art that when constructing the upper structure of the steel beam 2, temporary facilities such as escalators and ladder cages are not convenient to move, thereby affecting the construction efficiency.

[0030] join Figure 2As shown, in some optional embodiments, the cross plate 11 is provided with a through hole 111, and the adjusting rod 131 is penetrated through the through hole 111. In this embodiment, the adjusting rod 131 is penetrated through the through hole 111 provided in the cross plate 11. The extension direction of the steel beam 2 is regarded as the longitudinal direction, and the extension direction perpendicular to the steel beam 2 is regarded as the transverse direction. At this time, the transverse length of the cross plate 11 is greater than the transverse length of the steel beam 2. In some other embodiments, the adjusting rod 131 can be installed on the side of the cross plate 11, such as fixing a through ring on the side of the cross plate 11, and the adjusting rod 131 can be penetrated in the through ring.

The movable adjustment component 13 also includes a fixing nut 133, which is threadedly connected to the adjusting rod 131, and the fixing nut 133 is installed on the side of the cross plate 11 away from the fixing plate 132. By cooperating with the fixing nut 133 and the adjusting rod 131, the distance between the fixing plate 132 and the cross plate 11 in the vertical direction can be adjusted more conveniently. Preferably, the fixing nut 133 and the fixing plate 132 are installed on opposite sides of the cross plate 11, and the fixing nut 133 is located on the top surface of the cross plate 11 in the vertical direction. When the staff needs to adjust the tightness of the fixing nut 133, they can make adjustments by standing on the steel beam 2, thereby simplifying the construction process.

In the present embodiment, the anti-slip gasket 134 is configured as a metal ring structure. Compared with rubber or other materials, the metal anti-slip gasket 134 is more wear-resistant during use, and the ring structure can also be adapted to the shape of the fixing nut 133. In some other embodiments, the anti-slip gasket 134 can also have other shapes, such as square.

[0032] In some optional embodiments, the movable and fixed component 1 includes two transverse plates 11, and the two transverse plates 11 are arranged in parallel.

In this embodiment, two columns 321 are fixed in each transverse plate 11, and the four columns 321 in the two transverse plates 11 are connected to each other to form a square. The support platform 31 is installed on the top surface of the square structure at this time. This arrangement method not only meets the supporting performance of the columns 321, but also saves materials and makes the overall weight of the steel structure installation platform lighter and easier to move. In some other embodiments, the number of columns 321 connected in each transverse plate 11 can also be three or more, and the number of columns 321 in the two transverse plates 11 can also be different. Preferably, the upright posts 321 are fixed to the horizontal plate 11 by rigid connection.

[0033] In some optional embodiments, the support platform 31 includes a plurality of cross bars 311, and both ends of each cross bar 311 are respectively fixed to two adjacent columns 321. In this embodiment, both ends of each cross bar 311 are respectively fixed to two adjacent columns 321, and four cross bars 311 are respectively fixed to the columns 321 to form a square frame, see Figure 5 As shown, the support platform 31 also includes a mesh 312, and the mesh 312 is erected on the top of a square frame surrounded by a plurality of the cross bars 311. The mesh 312 may be a steel mesh 312, and the steel mesh 312 is installed on the top of the cross bar 311. The staff stands on the steel mesh 312 to work. The steel mesh 312 structure has a strong supporting force and a small weight, and can be easily moved while meeting the standing requirements of the staff.

[0034] Preferably, the support platform 31 also includes a plurality of reinforcement rods 313, the two ends of the reinforcement rods 313 are respectively fixed to two cross bars 311 adjacent to or oppositely arranged along the frame, that is, the reinforcement rods 313 are installed in the square frame surrounded by the cross bars 311, so that the support platform 31 has stronger supporting force, higher safety and stability.

[0035] In some optional embodiments, the working platform 3 also includes a guardrail structure 33, and the guardrail structure 33 is installed on the side of the supporting platform 31 away from the column 321. When the staff works on the supporting platform 31, they will tie a safety rope to ensure the safety of the staff working at high altitude. In this embodiment, a guardrail structure 33 is set in the working platform 3 to enhance the safety of the steel structure installation platform.

[0036] In some optional embodiments, the guardrail structure 33 may include: a plurality of connecting rods 331, one end of each connecting rod 331 is respectively connected to the column 321, and the connecting rod 331 extends toward the side away from the cross plate 11. In this case, the connecting rod 331 and the column 321 are an integrally formed structure, and the connecting rod 331 is an extension of the column 321, so that the guardrail structure 33 has stronger stability; a plurality of railings 332, each of which is respectively connected to two adjacent connecting rods at both ends. 331, the railing 332 and the connecting rod 331 are perpendicular to each other, and the height of the railing 332 in the vertical direction is set so that when the staff stands on the steel mesh 312, the railing 332 is located at the waist to chest of the staff. Since the connecting rod 331 and the column 321 are integrally formed at this time, the connecting rod 331 also forms a three-dimensional structure with a quadrilateral cross-section. At this time, the railing 332 is not set between two adjacent connecting rods 331, so that the staff can enter or walk out from this side.

[0037] Preferably, at least one of the connecting rods 331 is equipped with a safety rope threading ring at one end away from the column 321. The safety rope threading ring can be used to pass the safety rope tied to the worker through the ring. When the safety rope is free in the air, it may affect the construction of the workers. Therefore, the safety rope threading ring is set to confine the safety rope in the ring, thereby effectively reducing the impact of the safety rope on the construction process.
