Description

Technical Field

[0001] The present invention relates to the technical field of aluminum formwork for composite panels in construction engineering, and in particular to a tool-type construction method suitable for the structural form of composite panel aluminum formwork. Background Art

[0002] With the gradual promotion of prefabricated construction in my country's construction industry and the increasingly high requirements for project quality, a large number of projects with composite slab + aluminum formwork structures have emerged.

[0003] The composite slab + aluminum formwork system is a highly efficient combination of prefabricated buildings and new formwork technology. Its advantages are mainly reflected in construction efficiency, quality control, cost-effectiveness, etc., as follows:

[0004] 1. Construction efficiency is significantly improved

[0005] While the composite slabs are prefabricated in the factory, aluminum formwork installation, steel bar binding and other processes can be carried out simultaneously on site, reducing the linear waiting time of "formwork → reinforcement binding → pouring" in traditional construction, and significantly shortening the overall construction period.

[0006] The aluminum formwork adopts a modular design and can be quickly assembled on site. Compared with traditional wooden formwork, the installation time is greatly shortened and no on-site cutting is required, saving labor.

[0007] As a prefabricated component, the composite slab is installed in place and used together with the aluminum formwork as the formwork for the cast-in-place layer, which greatly reduces the workload of supporting the formwork and the amount of cast-in-place, effectively improving construction efficiency and shortening the construction period.

[0008] 2. Mass accuracy is greatly optimized

[0009] The processing accuracy of aluminum formwork reaches ±1mm. After on-site assembly, the verticality of wall columns and the flatness of floor slabs have an error of ≤5mm, which far exceeds the traditional wooden formwork (error ≤8mm).

[0010] The aluminum formwork support system has high rigidity, which can effectively control the deformation during concrete pouring and reduce the risk of floor cracks.

[0011] 3. Comprehensive improvement of cost-effectiveness

[0012] A set of aluminum molds can be used more than 300 times, which is much higher than wooden molds (5 to 8 times). With a high turnover rate, the long-term use cost is only 1 / 3 to 1 / 2 of that of wooden molds.

[0013] The shortened construction period brings hidden cost savings, such as the rental fees of equipment such as tower cranes and construction elevators.

[0014] However, there are still the following problems in the construction process of composite slab + aluminum formwork combination:

[0015] 1. It is difficult to set up protective structures during floor construction: When the composite slab is constructed in combination with aluminum formwork, the aluminum formwork usually adopts a frame structure with multiple openings, which is not only inconvenient to construct but also poses a great safety hazard. If the traditional horizontal opening protection method is used, it is necessary to remove the protection before hoisting the composite slab to form a protective vacuum period. If the full bottom formwork method is used, the construction cost will be greatly increased.

[0016] 2. Insufficient support in the composite slab, easy to deform and deflect: Large-span composite slabs often lack effective support in the slab, resulting in cracking and deformation during the casting process.

[0017] 3. The installation of the diagonal support of the vertical component formwork is not stable: Since the conventional cast-in-place layer of the composite slab is often only 6 to 7 cm, the buried depth of the diagonal brace support of the aluminum formwork in this cast-in-place layer is insufficient, which can easily cause problems such as unstable support and plate deformation.

[0018] 4. The hoisting of composite panels and the assembly of aluminum molds are prone to deviations in installation direction and position, which may result in the inability to correctly position reserved holes and stressed steel bars. Summary of the Invention

[0019] The present invention aims to provide a tool-type construction method suitable for the composite plate aluminum formwork structure, so as to solve the problems in the prior art of difficulty in setting up floor construction protection, insufficient support in the composite plate, and easy deformation and deflection during the combined construction of the composite plate and aluminum formwork.

[0049] As the preferred technical solution:
