Description

Technical Field

[0001] The present invention relates to the technical field of super-high atrium decoration construction, and particularly to an adaptive lifting platform for super-high atrium ceiling and side wall decoration and a construction method therefor. Background Art

[0002] In traditional high-altitude operations in atriums, scaffolds or fixed lifting platforms are mostly used, which have problems such as long installation periods, poor flexibility, and difficulty in adapting to complex-shaped construction. When constructing a super-high atrium with a height ≥ 15 meters, the existing equipment has the following defects: the cost of scaffold erection is high and it affects cross-operation; the stability and safety of high-altitude operations are insufficient.

[0003] Therefore, in view of the above technical problems, it is necessary to propose an adaptive lifting platform for super-high atrium ceiling and side wall decoration and a construction method therefor. Summary of the Invention

[0004] The purpose of the present invention is to provide an adaptive lifting platform for super-high atrium ceiling and side wall decoration and a construction method therefor. When in use, by controlling the length of the guide chain released by the electric hoist, the hoisting and lifting of the main keel can be achieved, eliminating the need for scaffold erection and solving the above technical problems.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

The structural roof truss is installed on top of the structural wall. The structural roof truss is provided with a plurality of suspension points. The upper end of the electric hoist is connected to the suspension point, and the lower end of the electric hoist is connected to the lifting platform. The platform safety net is arranged around the lifting platform, and the control box is connected to the electric hoist.

[0007] Preferably, the structural roof truss is made of a steel frame.

[0008] Preferably, the lifting platform includes a main keel, profiled steel sheets, and secondary keels. A plurality of secondary keels are lapped on the main keel, and the profiled steel sheets are installed on the secondary keels.

[0009] Preferably, the main keel is provided with keel lugs connected to the electric hoist.

[0010] Preferably, both the main keel and the secondary keel are made of rectangular steel pipes with a cross-sectional size of 400 mm × 200 mm × 5 mm.

[0011] Preferably, the upper surface of the profiled steel sheet is provided with anti-slip lines.

[0015] S1. Structural checking calculation, checking the bearing capacity of the roof structural beam according to the atrium span;

[0016] S2. Mark the positions of the electric hoists 4 on the structural roof truss according to the original design drawings, and take good hoisting point measures, and install the lifting platform on the ground;

[0017] S3. The lifting platform is lifted by an electric hoist and lifted synchronously through a control box. During the lifting process of the lifting platform, it is necessary to stop regularly to check the electric hoist, the hoist chain and the suspended formwork to ensure that the system is always in a horizontal state during the lifting process until the design elevation;

[0018] S4. After the installation of the lifting platform is completed, the construction load should be controlled when entering the next process to ensure that the construction load is 2 KN / m2, and at the same time, the material stacking should be avoided from being concentrated;

The deformation deflection calculation formula of the structural roof truss is: Where q k is the load standard value, E is the elastic modulus of the material, I is the moment of inertia of the cross section, [v] is the allowable deflection, and the bending bearing capacity checking calculation formula of the structural wall is: Where ρ is the reinforcement ratio, h0 = h - a s , h0 is the effective height, and the crack checking calculation formula of the structural wall is w max represents the maximum crack width calculated according to the quasi-permanent combination or standard combination of loads and considering the influence of long-term action, and the unit is usually mm, which is the target value of the formula calculation. α c is the influence coefficient of the non-uniform coefficient of longitudinal tensile reinforcement strain between cracks; ψ is the non-uniform coefficient of longitudinal tensile reinforcement strain between cracks, ρ te is the effective reinforcement ratio, [w] is the allowable crack width, r is the coefficient related to the surface characteristics of the longitudinal tensile reinforcement, σ sk is the stress of the longitudinal tensile reinforcement of the reinforced concrete member calculated according to the standard combination or quasi-permanent combination of loads, Es The elastic modulus of the steel bars, c is the distance from the outer edge of the outermost layer of longitudinally tensioned steel bars to the bottom edge of the tensioned zone, and d is the diameter of the longitudinally tensioned steel bars, with the unit of mm.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. The present invention changes the status quo of high traditional construction costs and low efficiency in the fine decoration of ultra-high atriums, greatly improves work efficiency. When the invention is specifically used, the input of formwork materials is small and the construction period is short. In future similar fine decoration constructions of ultra-high atriums, the platform system can be customized and improved according to the actual situation on site, so that the project can be completed efficiently and safely.

[0023] 2. The structural roof truss adopts a steel frame, which has high strength and good stability and can provide reliable support for the entire lifting platform. The lifting platform adopts a combined structure of main keels, secondary keels and profiled steel sheets. The main keels and secondary keels adopt rectangular steel pipes and are provided with triangular reinforcing plates. Anti-slip patterns and grid reinforcing ribs are respectively arranged on the upper and lower surfaces of the profiled steel sheets, greatly improving the strength, stiffness and load-bearing capacity of the lifting platform, ensuring the safety of construction personnel and materials. The setting of the platform safety net effectively prevents construction personnel and items from falling, improving the safety of construction.

[0024] 3. The coordinated use of electric hoists and control boxes realizes the synchronous lifting of the lifting platform, can flexibly adjust the platform height according to construction needs, adapts to different construction height requirements, improves construction efficiency. The design of the keel ear plates facilitates the connection and disassembly of the electric hoists and the lifting platform, and is convenient for the installation and maintenance of the equipment.

[0025] 4. In the construction method, structural checking calculations are carried out first to ensure the safety of the structure, avoid safety accidents caused by insufficient structural load-bearing capacity. During the lifting process, the construction load is regularly inspected and controlled to ensure the smooth operation of the lifting platform and the safety of the construction process.

The electric hoist 4 realizes the lifting function of the platform. The control box 10 is used to control the operation of the electric hoist 4. The platform safety net 5 ensures the safety of construction workers. This structural design enables the platform to adapt to the construction environment of the ultra-high atrium, improving the convenience and safety of construction.

[0041] Furthermore, the structural roof truss 1 is made of a steel frame.

[0042] The beneficial effects of adopting the above technical solution: The structural roof truss 1 is made of a steel frame. The steel frame has high strength and toughness and can bear large loads.
