Description

Technical Field

[0001] The present invention relates to the technical field of construction, and more specifically, to a construction platform system based on prefabricated steel structure buildings.

Background Art

[0002] Conventional outer wall scaffolds and attached lifting scaffolds generally only provide external protection for the main structure construction and cannot provide an operation platform for secondary structure and outer wall construction. In addition, it is necessary to remove the external scaffold and then install an electric gondola, resulting in high equipment usage costs, high safety risks during installation and removal, and significant safety risks during the construction process. Therefore, there is a need for a platform and safety management system that can not only provide a construction protection platform but also an operation platform for construction, and support the coordination of the main structure, secondary structure, and outer wall construction processes. Thus, the present invention proposes a construction platform system based on prefabricated steel structure buildings that can not only provide external protection for the main structure construction but also provide an operation platform for secondary structure and outer wall construction. Moreover, it has a smart control system that can reasonably manage the construction process and construction period according to the progress of the construction site, and comprehensively ensure the safety of construction.

[0010] Hereinafter, in order to fully understand the object, features and effects of the present invention, the idea, specific structure and generated technical effects of the present invention will be clearly and completely described with reference to the embodiments and drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention. In addition, all fastening / connection relationships related to the patent do not only refer to the direct connection of members, but also, according to the specific implementation situation, a better fastening structure can be formed by adding or reducing fastening auxiliary members. Each technical feature in the creation of the present invention can be combined with each other as long as they do not conflict with each other.

[0011] As shown in Figure 1, the present invention discloses a construction platform based on a prefabricated steel structure building. The construction platform system based on the prefabricated steel structure building includes a steel structure building, a support member 5, a first construction platform 1, a first driving unit 2, a second construction platform 3 and a second driving unit 4. The support member 5 is vertically fixed to the ground and fixed to the floor slab 6 of the steel structure building. Both the first construction platform 1 and the second construction platform 3 are slidably connected to the support member 5. The first driving unit 2 is installed between the support member 5 and the first construction platform 1, fixed to the first construction platform 1, driving the first construction platform 1 to slide up and down along the support member 5 and approaching the bottom of the support member 5. The second driving unit 4 is installed between the support member 5 and the second construction platform 3, fixed to the second construction platform 3, approaching the bottom of the support member 5, and driving the second construction platform 3 to slide up and down along the support member 5. Specifically, the first driving unit 2 and the second driving unit 4 include a driving device, a driving wheel and a driving guide rail. The driving guide rail is fixedly attached to one side surface of the support member 5. The driving wheel is fixed to the driving shaft of the driving device and slidably connected to the driving guide rail. Both the first construction platform 1 and the second construction platform 3 include vertical poles, reinforcing frames, walking deck plates, Bailey trusses, limiters and protective nets. Both the reinforcing frame and the Bailey truss are embedded in the support member 5, and the reinforcing frame and the Bailey truss are provided parallel to each other. The vertical pole penetrates through the reinforcing frame, the walking deck plate and the Bailey truss at the same time and is fixed to the Bailey truss and the reinforcing frame. The limiter is attached to the upper part of the vertical pole and the bottom of the Bailey truss. The protective net is laid on the side away from the steel structure building of the construction platform.

[0012] In this embodiment, the support member 5 is fixedly installed perpendicular to the ground and connected to the floor slab 6 of the steel structure building. This design ensures the stability and safety of the construction platform, and the support member 5 serves to place and support the construction platform. The first construction platform 1 and the second construction platform 3 are slidably connected to the support member 5, enabling workers to work at different heights. Their positions and heights can be adjusted according to construction requirements, and multiple operating layers in the same support structure maximize construction efficiency. The design of the first drive unit 2 and the second drive unit 4 ensures that drive units are arranged to control and drive each construction platform to move up and down along the support member 5. Specifically, both the first construction platform 1 and the second construction platform 3 include vertical poles, reinforcing frames, walking deck plates, Bailey trusses, limiters, and safety nets. The reinforcing frames and Bailey trusses are fitted into the support member 5 and provided in parallel to provide the main structural support for the construction platform. The vertical poles are fixed by passing through the reinforcing frames, walking deck plates, and Bailey trusses to ensure the stability and load-bearing capacity of the construction platform. The limiters are attached to the upper part of the vertical poles and the bottom of the Bailey trusses and are used to limit the up and down movement range of the construction platform and enhance safety. The safety nets are laid on the side away from the steel structure building of the construction platform and are used to prevent accidental falls of workers and ensure construction safety. This assembled steel structure building construction platform system can not only provide external protection for the main structure construction of the steel structure building, but also provide a construction operation platform for secondary structure and outer wall construction. By driving the construction platform with the drive unit to slide up and down along the support member 5, it is possible to reasonably manage the construction process and construction period according to the progress of the construction site, thereby not only ensuring construction integrity but also improving construction efficiency.

[0013] As shown in FIG. 2, the present solution further provides a construction method based on prefabricated steel structure buildings, which is applied to the construction platform system based on the above prefabricated steel structure buildings. The construction method based on the prefabricated steel structure buildings includes the following steps.

[0014] Step S10, steel structure construction: Install the main structure of the steel structure building and construct the construction platform system based on the prefabricated steel structure building. Specifically, the steel structure construction is as follows: First, install the steel columns and steel beams of the foundation floor of the main structure of the steel structure building, and start assembling the vertical poles and frames of the construction platform system. Then, attach the vertical poles to the steel beams, and perform internal frame erection, formwork installation, steel bar binding, PC member installation, and electrical and mechanical piping and wiring embedding for the floor slab 6 of the steel structure building. Next, attach the vertical poles to the steel beams on the upper floor, and the construction platform rises to the upper floor, and perform internal frame erection, formwork installation, steel bar binding, PC member installation, and electrical and mechanical piping and wiring embedding for the upper floor. Finally, repeat in this way. When the construction protection platform on the upper floor rises to the roof, the main structure construction is completed. The specific method of embedding the electrical and mechanical piping and wiring is as follows: First, mark the positions and routes of the piping and wiring on the formwork according to the electrical and mechanical construction design drawings. Then, provide reserved holes or grooves on the formwork, and pass the piping and wiring through the reserved holes or grooves and fix them according to the requirements of the design drawings. Finally, inspect the embedded piping and wiring, ensure that the positions are accurate and firmly fixed, and then pour concrete for the floor slab 6.

[0015] Step S20, secondary structure construction: Use the construction platform system to install ALC boards and block structures on the wall part of the steel structure building.

[0016] Step S30, mortar coating construction: Apply mortar coating to the surface of the wall of the steel structure building to ensure the flatness of the wall surface.

[0017] Step S40, waterproof construction: Perform waterproof treatment on the upper part and wall of the steel structure building.

[0018] Step S50, Heat insulation board construction: Attach heat insulation materials to the outer walls and roofs of steel structure buildings.

[0019] Step S60, External window installation construction: Install external windows on the outer walls of steel structure buildings.

[0020] Step S70, Stone-like coating material construction: Spray and paint stone-like coating materials on the outer walls and interior wall surfaces of steel structure buildings.

[0021] For the specific construction methods of Steps S20 to S70, first, complete the secondary structure construction, mortar coating construction, waterproof construction, heat insulation board construction, external window installation construction, and stone-like coating material construction of the lower floors of the steel structure building on the construction platform. Then, the construction platform rises to the floor below the top floor, removes the vertical poles attached to the top floor, and performs secondary structure construction, mortar coating construction, waterproof construction, heat insulation board construction, external window installation construction, and stone-like coating material construction on the top floor of the steel structure building. Finally, the construction platform descends floor by floor, and performs secondary structure construction, mortar coating construction, waterproof construction, heat insulation board construction, external window installation construction, and stone-like coating material construction on each floor of the steel structure building.

[0022] When specifically implementing the present invention, taking the example that the steel structure building is provided with 2N floors, the construction process and operation procedures are specifically as follows.

[0023] (1) When the construction of the steel structure main body reaches the Nth floor, after installing the first construction platform 1, perform the secondary structure construction (ALC board or prefabricated structure) on the first floor. At this time, the synchronous construction of the main structure on the upper floor and the secondary structure on the lower floor can be started.

[0024] (2) When the construction of the main structure on the upper floor reaches the 2Nth floor, the secondary structure construction on the lower floor reaches the Nth floor. Lower the second construction platform 3 to the Nth floor to perform secondary structure construction, lower the first construction platform 1 to the first floor to perform mortar coating construction on the outer wall, and start the synchronous construction of the secondary structure on the upper floor and the mortar coating on the outer wall of the lower floor.

[0025] (3) When the secondary structure construction on the upper floor reaches the 2Nth floor, the mortar coating construction on the outer wall of the lower floor reaches the Nth floor. Lower the second construction platform 3 to the Nth floor to perform the mortar coating construction on the outer wall, and lower the first construction platform 1 to the first floor to perform the waterproof construction on the outer wall, and start the synchronous construction of the mortar coating on the upper floor outer wall and the waterproof on the lower floor outer wall.

[0026] (4) When the mortar coating construction on the upper floor outer wall reaches the 2Nth floor, the waterproof construction on the outer wall of the lower floor reaches the Nth floor. Lower the second construction platform 3 to the Nth floor to perform the waterproof construction on the wall, and lower the first construction platform 1 to the first floor to perform the installation construction of the heat insulation board on the outer wall, and start the synchronous construction of the waterproof on the upper floor outer wall and the installation of the heat insulation board on the lower floor outer wall.

[0027] (5) When the waterproof construction on the upper floor outer wall reaches the 2Nth floor, the heat insulation board construction on the outer wall of the lower floor reaches the Nth floor. Lower the second construction platform 3 to the Nth floor to perform the heat insulation board construction on the outer wall, and lower the first construction platform 1 to the first floor to perform the window installation construction on the outer wall, and start the synchronous construction of the heat insulation board on the upper floor outer wall and the window installation on the lower floor outer wall.

[0028] (6) When the heat insulation board construction on the upper floor outer wall reaches the 2Nth floor, the window installation construction on the outer wall of the lower floor reaches the Nth floor. Lower the second construction platform 3 to the Nth floor to perform the window installation construction on the outer wall, and lower the first construction platform 1 to the first floor to perform the stone-like coating material construction on the outer wall, and start the synchronous construction of the window installation on the upper floor outer wall and the stone-like coating material on the lower floor outer wall.

[0029] (7) When the window installation construction on the upper floor outer wall reaches the 2Nth floor, the stone-like coating material construction on the outer wall of the lower floor reaches the Nth floor. Lower the second construction platform 3 to the Nth floor to perform the stone-like coating material construction on the outer wall, and lower the first construction platform 1 to the first floor to perform the removal construction.

[0030] When the stone finish coating construction on the outer wall of the upper floor reaches the 2Nth floor, prepare for the removal of attachments and the construction of attaching the climbing rails. Remove them after construction up to the 1st floor. Up to this point, the multi-platform construction is completed.

[0031] In this way, the construction method adopting the first construction platform 1 and the second construction platform 3 shortens the construction period by 50%. When constructing under more complex construction conditions, multiple construction platforms can be installed for construction. The procedure of the flow operation of the construction is consistent with the idea of this embodiment, significantly shortening the construction period and realizing a rapid construction flow. In addition, the construction platform system based on the assembled steel structure building can reasonably manage the construction process and the construction period according to the progress of the construction site by means of the smart control system, ensure the construction safety in all aspects, and support the smart construction management of the entire cycle of the assembled steel structure building.
