Description
Technical Field
The invention belongs to the technical field of laminated slab cast-in-place, and particularly relates to a construction structure of a laminated slab without adhering ash and a construction process thereof.
Background
The existing cast-in-place process of the laminated slab has a great disadvantage that after construction is finished and side formworks are removed, concrete ash 7 with the width of 20-30cm is generated at the edge of a top plate, the formation reason of the concrete ash 7 is directly related to the construction of the formworks, as shown in figures 3-4, two ends of the existing cast-in-place formwork 2 of the laminated slab are directly erected on beam formworks 1 at two sides, because the cast-in-place formwork 2 of the laminated slab has a certain thickness, the side formworks 5 are required to be erected for balancing, the upper surfaces of the side formworks and the upper surfaces of the cast-in-place formworks 2 of the laminated slab are positioned at the same horizontal height, the prefabricated laminated slab 6 is hoisted to a corresponding position, the side formworks 5 are arranged between the prefabricated laminated slab 6 and the beam formworks 1, when the concrete is cast in place, the concrete flows into gaps between the prefabricated laminated slab 6 and the side formworks 5 and flows downwards, so that the concrete is wasted and a very troublesome problem is caused, after the side formwork 5 is removed, concrete ash 7 with the width of 20-30cm can be formed on the laminated slab at the original side formwork 5, and the concrete ash 7 is very difficult to remove and must be removed, otherwise, other subsequent construction is influenced, and very large manpower can be wasted.
Disclosure of Invention
The invention provides a laminated slab construction structure free of dust adhesion and a construction process thereof, which can solve the problems pointed out in the background art.
The utility model provides a superimposed sheet is not stained with ash construction structures, includes beam template and superimposed sheet cast-in-place template, at least one side of beam template can be equipped with the recess identical with superimposed sheet cast-in-place template, the degree of depth of recess with superimposed sheet cast-in-place template thickness is unanimous, the beam template sets up a plurality of template along its length direction and prevents outer spacing subassembly that props, the template prevents outer spacing subassembly that props and is used for preventing that the beam template props out to both sides.
Preferably, the template anti-external-support limiting assembly comprises limiting square timbers on two sides and split bolts connected to the limiting square timbers on the two sides.
Preferably, the template anti-external-support limiting assembly is a U-shaped reinforced square timber.
A laminated slab construction process utilizing the construction structure comprises the following steps:
the method comprises the following steps: erecting a beam template at a corresponding position, and installing a template external-support-preventing limiting assembly along the length direction of the beam template;
step two: mounting a laminated slab cast-in-place template, and enabling two ends of the laminated slab cast-in-place template to be supported by grooves of the laminated slab cast-in-place template;
step three: hoisting the prefabricated composite slab to a corresponding position, and pouring concrete into the cast-in-place template of the composite slab;
step four: after the maintenance is finished, the corresponding template is removed;
the invention provides a laminated slab ash-free construction structure and a construction process thereof, wherein two ends of a cast-in-place template of the laminated slab are supported by grooves, and side templates are not required to be used for balancing, so that the erection of the side templates can be omitted, the side templates are omitted, namely, gaps between the laminated slab and the side templates can not be formed, after the cast-in-place is completed, concrete ash stains can not be formed at the edges, the waste of concrete is avoided, the later cleaning is also avoided, a large amount of labor is saved, but the side templates are omitted, two sides of the upper end of a beam template are likely to be outwards propped out, and the occurrence of external bracing of two sides of the upper end of the beam template can be effectively prevented by arranging a template external bracing limiting component.
