Description

Technical Field

[0001] The present invention mainly relates to the technical field of building construction, and in particular to a steel structure construction platform. Background Art

[0002] A steel structure is a building structure made of steel materials; it is primarily constructed by welding steel beams, steel columns, steel trusses, and other components. During the construction process, high-rise construction requires a suspended construction platform to support construction personnel.

[0003] In order to ensure the stability of workers during operation, the steel platform should be reinforced. If it is reinforced manually, in order to ensure the reinforcement effect, the workers are usually required to exert greater force to perform the reinforcement operation, which increases the workload of the workers. If pneumatic or hydraulic methods are used for reinforcement, it is inevitable to carry cylinders or hydraulic cylinders, which greatly increases the weight of the steel platform. Summary of the Invention

[0004] The technical solution of the present invention addresses the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technology. It mainly provides a steel structure construction platform to solve the technical problems raised in the above background technology.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] A steel structure construction platform for being installed on a support column, comprising a base and a guardrail installed on the side of the base, the guardrail having a built-in protective net, a plurality of pressing mechanisms provided on the base, the pressing mechanisms comprising two vertical frames opposite to each other, a screw being rotatably connected between the two vertical frames, a rotating assembly located outside the vertical frame being connected to an axis on one side of the screw, two moving blocks moving toward each other being threadedly connected to the screw, a lifting block being provided in the vertical direction of the midpoint of the screw, a connecting rod being rotatably connected between the lifting block and the two moving blocks, a transmission rod being connected to the lower end of the connecting rod, and the transmission rod being slidably connected to the base;

[0007] Each of the pressing mechanisms is provided with an extrusion mechanism at the lower end thereof, the extrusion mechanism comprising a mounting frame mounted at the lower end of the base, a reinforcement bar being rotatably mounted on the mounting frame, one end of the reinforcement bar being in contact with the support column, and the other end of the reinforcement bar being provided with a sliding block rotatably connected to the transmission rod;

[0008] The hinge point between the reinforcement strip and the mounting frame is set as a fulcrum, and the length of the reinforcement strip between the fulcrum and the support column is smaller than the length of the reinforcement strip between the fulcrum and the sliding block.

[0009] Preferably, the base is provided with a channel for accommodating the support column, and the base slides on the support column.

[0010] Preferably, there are at least two groups of the pressing mechanisms.

[0011] Preferably, the screw is provided with two sections of threads with opposite lines, and the intersection point of the two sections of threads is the midpoint of the screw.

[0012] Preferably, the rotating assembly includes a hexagonal nut connected to the axis of the screw, the hexagonal nut is rotatably mounted on the vertical frame, and the rotation of the hexagonal nut is driven by a wrench.

[0013] Preferably, a sliding groove is provided on the reinforcement bar, and the sliding block is slidably installed inside the sliding groove.

[0014] Preferably, a contact pressure plate is rotatably mounted on one end of the reinforcement strip via a torsion spring, and the side of the contact pressure plate away from the reinforcement strip faces the side wall of the support column.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] When the present invention is in use, when the construction platform moves to an appropriate height, the hexagonal nut is driven to rotate by the wrench, so that the screw is rotated, so that the two moving blocks move toward each other, thereby making the lifting block move downward, and the lifting block drives the sliding block to move through the transmission rod, and the pressing mechanism forms a simple scissor-type jack structure, and only a small rotational force is needed to make the lifting block have a large downward thrust, and the lifting block drives the sliding block to move through the transmission rod, and the sliding block makes one end of the reinforcement bar move downward and the other end move upward, so that the contact pressure plate is squeezed on the support column, and the squeezing mechanism forms a lever, and because the length of the reinforcement bar between the fulcrum and the support column is less than the length of the reinforcement bar between the fulcrum and the sliding block, only a small downward pressure needs to be applied to the sliding block, so that the contact pressure plate can generate a large squeezing force on the support column, so that the construction platform can obtain a better stabilization effect;

[0017] In summary, the downward pressure mechanism is used to form a simple scissor jack structure and the extrusion mechanism is used to form a lever structure, so that the workers only need to apply a small force to make the contact pressure plate produce a larger extrusion force on the support column, so that the construction platform can be better stabilized.

[0026] Please refer to the attached Figure 1 The present invention provides a technical solution: a steel structure construction platform for mounting on support columns 40. The base 10 is provided with a channel for accommodating the support columns 40. The base 10 slides on the support columns 40 and includes a base 10 and a guardrail 11 mounted on the side of the base 10. The guardrail 11 has a built-in protective net 12. The guardrail 11 can increase the protection of workers, and the protective net 12 can effectively prevent the falling of work tools on the construction platform, thereby increasing the safety of construction operations.

[0027] Please refer to the attached Figure 1 and 2 The base 10 is provided with a plurality of pressing mechanisms, and the pressing mechanisms are provided with at least two groups. The pressing mechanisms should be distributed equidistantly around the axis of the support column 40. This arrangement can further improve the clamping effect and make the construction platform more stable.

[0028] The downward pressure mechanism includes two vertical frames 20 facing each other, with a screw 21 rotatably connected between the two vertical frames 20. The screw 21 is provided with two sections of threads with opposite patterns, and the intersection of the two sections of threads is the midpoint of the screw 21. Two moving blocks 22 that move toward each other are threadedly connected to the screw 21. A lifting block 23 is provided in the vertical direction of the midpoint of the screw 21. A connecting rod 24 is rotatably connected between the lifting block 23 and the two moving blocks 22. The lower end of the connecting rod 24 is connected to a transmission rod 26, and the transmission rod 26 is slidably connected to the base 10. The screw 21 is driven to rotate, so that the two moving blocks 22 move toward each other, thereby causing the lifting block 23 to move downward. The lifting block 23 drives the sliding block 32 to move via the transmission rod 26. The downward pressure mechanism forms a simple scissor jack structure. Only a small rotational force is required to make the lifting block 23 have a large downward thrust.

[0029] Please refer to the attached Figure 1 and 3 One side of the screw rod 21 is axially connected to a rotating assembly located outside the vertical frame 20. The rotating assembly includes a hexagonal nut 25 axially connected to the screw rod 21. The hexagonal nut 25 is rotatably mounted on the vertical frame 20 and is driven by a wrench. Using a wrench to drive the hexagonal nut 25 can further reduce the force required by the operator.

[0030] The lower end of each pressing mechanism is provided with an extrusion mechanism, and the extrusion mechanism includes a mounting frame 30 mounted on the lower end of the base 10, and a reinforcing bar 31 is rotatably mounted on the mounting frame 30, one end of the reinforcing bar 31 is in contact with the support column 40, and the other end is provided with a sliding block 32 rotatably connected to the transmission rod 26, the reinforcing bar 31 is provided with a slide groove, and the sliding block 32 is slidably mounted inside the slide groove, and the hinge point of the reinforcing bar 31 and the mounting frame 30 is set as a fulcrum, and the length of the reinforcing bar 31 between the fulcrum and the support column 40 is less than the length of the reinforcing bar 31 between the fulcrum and the sliding block 32, and a contact pressure plate 33 is rotatably mounted on one end of the reinforcing bar 31 through a torsion spring, and the side of the contact pressure plate 33 away from the reinforcing bar 31 is toward the side wall of the support column 40, and the existence of the contact pressure plate 33 enables the reinforcing bar 31 to better apply extrusion force to the support column 40. The lifting block 23 drives the sliding block 32 to move through the transmission rod 26. The sliding block 32 causes one end of the reinforcement bar 31 to move downward and the other end to move upward, so that the contact pressure plate 33 is squeezed on the support column 40. The squeezing mechanism forms a lever, and since the length of the reinforcement bar 31 between the fulcrum and the support column 40 is less than the length of the reinforcement bar 31 between the fulcrum and the sliding block 32, it is only necessary to apply a small downward pressure to the sliding block 32 to make the contact pressure plate 33 produce a large squeezing force on the support column 40, so that the construction platform can obtain a better stability effect.

[0031] The specific operation process of the present invention is as follows:

[0032] When the construction platform moves to a suitable height, the hexagonal nut 25 is driven by the wrench to rotate, so that the screw 21 rotates, and the two moving blocks 22 move toward each other, thereby causing the lifting block 23 to move downward, and the lifting block 23 drives the sliding block 32 to move through the transmission rod 26. The pressing mechanism forms a simple scissor jack structure, and only a small rotational force is needed to make the lifting block 23 have a large downward thrust. The lifting block 23 drives the sliding block 32 to move through the transmission rod 26, and the sliding block 32 causes one end of the reinforcement bar 31 to move downward and the other end to move upward, so that the contact pressure plate 33 is squeezed on the support column 40. The squeezing mechanism forms a lever, and since the length of the reinforcement bar 31 between the fulcrum and the support column 40 is less than the length of the reinforcement bar 31 between the fulcrum and the sliding block 32, only a small downward pressure needs to be applied to the sliding block 32, so that the contact pressure plate 33 can generate a large squeezing force on the support column 40, so that the construction platform can obtain a better stability effect.

[0033] The above description of the present invention is exemplified in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
