Assembly type laminated slab splicing seam suspension type formwork structure and construction method thereof

Abstract

The invention discloses an assembly type laminated slab splicing seam suspension type formwork structure and a construction method thereof. The formwork structure comprises a wall body (1), and is characterized in that cast-in-place layers (5) are arranged on the upper surfaces of prefabricated bottom plates (2), splicing seams (6) are reserved between every two adjacent prefabricated bottom plates (2), a plurality of sliding seats (9) are installed on hoisting sliding rails (8) on horizontal steel beams (7), the bottoms of the sliding seats (9) are fixedly provided with lifting rod fixing frames (10), the lifting rod fixing frames (10) are connected with the upper ends of vertical lifting rods (11) through locking adjustable devices, and a plurality of splicing seam bottom formworks (12) are arranged under the splicing seams (6). The formwork structure is reasonable in structure and convenient to mount and dismount, and does not occupy the space of the next floor; and the height of the bottom formwork can be accurately adjusted according to needs, stress is uniform, local deformation and cracking cannot occur after formwork removal, the overall forming effect of the floor slab is good, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to a splicing joint suspension type formwork structure and a construction method thereof, in particular to an assembled laminated board splicing joint suspension type formwork structure and a construction method thereof, belonging to the technical field of construction engineering. Background technique [0002] With the wave of prefabricated building construction in my country's construction industry, the production methods in the construction field have undergone great changes. The floors in prefabricated concrete structures mostly use concrete truss and steel bars to laminate floors. The prefabricated laminate is composed of a prefabricated base plate and a cast-in-place floor slab at the bottom, and the whole floor slab is integrated by the combination of the prefabricated base plate and the cast-in-place concrete. Due to the limited width of the prefabricated floor, the adjacent prefabricated floor needs to reserve a certain w...

Problems solved by technology

[0003] The first purpose of the present invention is to solve the difficulty of installation and disassembly by setting up scaffolding formwork during construction of the existing prefabricated laminated slab, and the adjustability is not good, which will affect the construction of the next floor and the simultaneous indoor construction and The decoration project has adverse effects, and it is easy to lift the prefabricated floor during the process of supporting the formwork, which affects the construction accuracy of the floor. After the formwork is removed, local deformation and cracking are easy to occur. , adopts the suspended formwork structure above, does not occupy the space of the next floor, and can precisely adjust the height of the bottom formwork according to the needs, and the force is uniform, avoiding the prefabricated bottom plate from jacking up, and there will be no local deformation and damage after the formwork is removed. In the case of cracking, the overall forming effect of the floor slab is good, and the construction efficiency has been improved. A prefabricated laminated slab seam suspension formwork structure

[0004] The second purpose of the present invention is that it is difficult to support the formwork of the existing prefabricated laminated slabs. The traditional formwork method will adversely affect the construction of the next floor and the simultaneous indoor construction and decoration works. It is not high, there are many joints, and it is easy to have connection and fixing problems and grout leakage problems. It cannot reflect the defects and shortcomings of the advantages of prefabricated construction. It provides a reasonable process, simple construction, high formwork accuracy, and will not cause damage to the next The construction of the first floor and the simultaneous interior construction and decoration work have caused adverse effects, the problem of connection and fixation and the problem of grout leakage have been solved, and the construction quality of the prefabricated laminated slab has been improved.
