Description
Technical Field
The invention relates to the field of engineering construction, in particular to a novel hoisting method of a cast-in-place concrete disassembly-free template.
Background
In the field of engineering construction, when a reinforced concrete structure is cast in situ with concrete, a large number of wooden templates are needed to be used, the wooden templates need to be removed and cleaned after the concrete is formed and then used, the use of the templates has large consumption of wood, the use frequency is low, a large amount of manpower and material resources are consumed during removal and cleaning, the construction cost is increased, the template removal duration is long, and the construction period is seriously influenced.
Therefore, at present, part of projects begin to use cast-in-place concrete non-dismantling formworks to replace wooden formworks for construction, however, the existing hoisting cast-in-place concrete disassembly-free template is hoisted by adopting a steel wire rope, the hardness of the steel wire rope is high, the contact area with the concrete disassembly-free template is small, therefore, the pressure to the non-dismantling formwork is larger, the stress of the concrete non-dismantling formwork is uneven, the cast-in-place concrete non-dismantling formwork takes a non-combustible composite expanded polystyrene board as a heat-insulating core material, the polymer mortar with the built-in alkali-resistant glass fiber mesh cloth is used as a non-dismantling formwork of a building with two reinforcing layers, the polystyrene heat-insulating core plate and the polymer mortar reinforcing layer are easy to damage, tilt and tip in the traditional steel wire rope hoisting process to form quality problems of edge and corner deletion and the like, the quality problems of edge and corner deletion and the like cause the increase of project cost, and the polymer mortar non-dismantling formwork is difficult to pass in project household acceptance and is easy to be complained by owners after delivery.
Disclosure of Invention
The invention aims to: aiming at the problems that the existing cast-in-place concrete non-dismantling template scheme is easy to cause damage, the quality problems of edge-lacking broken angles and the like are formed, the project cost is increased, the cast-in-place concrete non-dismantling template is difficult to pass in the process of project individual examination and acceptance, and the cast-in-place concrete non-dismantling template is easy to be complained by owners, the novel method for hoisting the cast-in-place concrete non-dismantling template is provided, the quality problems of material damage, edge-lacking broken angles and the like in the hoisting process can be avoided, and the project cost is reduced.
In order to achieve the above purpose, the invention provides the following technical scheme:
a new hoisting method of a cast-in-place concrete disassembly-free template comprises the following steps:
the method comprises the following steps: the assembly module is characterized in that cast-in-place concrete disassembly-free templates are assembled into modules on the sleepers, and the modules are cuboids;
step two: placing angle steel, wherein the angle steel is respectively placed on the long edge corners of the upper surface of the topmost layer and the lower surface of the bottommost layer of the module;
step three: sleeving the hanging belt into the module, wherein the hanging belt is in contact with the module;
step four: trial hoisting, namely hoisting the module by using hoisting equipment to separate and contact the bottom surface of the module from the upper surface of the sleeper so as to tighten the sling;
step five: and hoisting, namely hoisting the module to a destination by using hoisting equipment after hoisting the hoisting equipment into the hoisting ring.
As an optimized technical scheme, the length of the angle steel in the step two is consistent with the length of the long edge of the cast-in-place concrete non-dismantling template, so that the problem that the hanging strip is in direct contact with the non-dismantling template and damages the concrete non-dismantling template due to the fact that the length of the angle steel is shorter than the length of the long edge of the concrete non-dismantling template can be avoided, and the problem that the angle steel collides with other objects in the hoisting process due to the fact that the length of the angle steel is longer than the length of the long edge of the concrete non-dismantling template can be avoided, and safety accidents are caused.
According to a preferable technical scheme, the side wall of the angle steel is provided with a U-shaped side lug, a flat through hole is formed between the U-shaped side lug and the side wall of the angle steel, and the hanging strip penetrates through the through hole.
As the preferred technical scheme, all set up the bearing subassembly on the both ends lateral wall of angle steel, the bearing subassembly includes bottom plate, support column and locking bolt, and the welding has the bottom plate on the angle steel of non-dismantling template below, and the middle part of bottom plate is pegged graft and is had the support column, and passes through locking bolt fixed connection between bottom plate and the support column.
As a preferred technical scheme, an upper supporting plate is welded on the side wall of the upper end of the supporting column.
