Description

Technical Field

[0001] The present invention belongs to the technical field of building construction. Specifically, it is a construction method combining a detachable truss floor slab and aluminum formwork. Background Technique

[0002] At present, the combination of detachable floor slabs and aluminum formwork has been increasingly used in buildings due to its functionality, environmental protection, and high efficiency. Since the detachable floor slab and aluminum formwork are produced by two different professional suppliers and both have the function of bearing the concrete load, when the floor slab is laid flat on the aluminum formwork, quality problems such as deformation, offset, and leakage of mortar may occur at the joint where there is no aluminum formwork.

[0003] For example, in Chinese Patent CN 118273528 A, with the invention name of "Construction Method for Combinining Demountable Reinforced Truss Plate and Wall Aluminum Formwork", a construction method for combining a demountable reinforced truss plate and a wall aluminum formwork is disclosed, including connection steps such as inverted "L" - shaped connectors, pin - and - washer assemblies, etc., realizing the on - site fixation and disassembly of the truss plate and the aluminum formwork. However, it does not specifically reinforce the joint of the floor slab, but only relies on the inverted "L" - shaped connectors and pin - and - washer assemblies for fixation, without arranging longitudinal bar binding at the joint of the truss plate, and thus cannot effectively prevent the concrete offset and mortar leakage at the joint. Moreover, this solution does not clarify the lower support measures at the joint, without the step of adding vertical poles to support at the lower part of the joint. When there is no lateral aluminum formwork to support at the joint, deformation is likely to occur. In addition, this solution does not clarify the control of the relative position between the joint and the aluminum formwork, and cannot ensure that the joint always has a good supporting surface.

[0004] Another example is Chinese Patent CN 113216486 B, with the invention name of "Reinforced Truss Floor Slab and Aluminum Alloy Cross - Node Structure and Construction Method", which discloses a structure of arranging vertical back ribs at the horizontal back ribs of the aluminum alloy formwork and fixing the combined K - plate through pin - and - washer assemblies to realize the cross - node connection of the truss plate and the aluminum alloy formwork. However, this solution has complex connection nodes and is not conducive to rapid construction. The fixation through back ribs and pins is cumbersome, and the construction efficiency is low. It does not check the cleaning of surface garbage and ash residue after the installation of the floor slab and the tightness of the joint, and leakage of mortar is likely to occur. There is no additional longitudinal bar to strengthen the joint, relying only on the formwork nodes and lacking strength and rigidity.

[0005] Another example is Chinese Patent CN 208650364 U, with the invention name of "A Demountable Truss Floor Slab Structure", which discloses a detachable structure design of the bottom plate and the truss unit, realizing the reuse of the bottom formwork through the fixation of convex strips and bolts. However, this solution only considers the detachable property of the truss plate itself and does not involve the problem of cooperative construction with the aluminum formwork. It does not design special lower support or sealing treatment at the joint, and cannot avoid quality defects such as offset and leakage of mortar. Only positioning through the convex blocks of the bottom plate and the connectors, without further strengthening the joint of the floor slab with longitudinal bars, lacking firmness.

[0006] For another example, in Chinese Patent CN 105089192 A with the invention title of a detachable bottom formwork steel truss floor slab and its assembly method, it discloses a method of simplifying the disassembly and assembly of the bottom formwork and the truss by improving the connecting parts, with an emphasis on mechanized production and the convenience of on-site removal of the bottom formwork. However, this technology only focuses on the disassembly of the bottom formwork and factory production, without considering the on-site combination and load-bearing cooperation of aluminum formwork. Although the production and removal are simplified, there are no control measures for the joint sealing and leveling during the construction process, and the problem of joint deformation after installation cannot be solved. It does not propose steps for finished product protection and inspection after installation (cleaning of garbage and ash), which affects the project quality and safety.

[0007] In summary, the prior art has the above-mentioned various inconveniences and problems. Summary of the Invention

[0008] The purpose of the present invention is to propose a construction method for combining a safe and reliable detachable truss floor slab with aluminum formwork.
