Construction method for long-span hanging vestibule type template support system

Abstract

The invention belongs to the technical field of construction engineering and in particular relates to a construction method for a long-span hanging vestibule type template support system. The construction method comprises the following steps: (1) selecting the position of a hanging steel beam; (2) paying off the hanging steel beam in a positioning mode; (3) installing the hanging steel beam, and welding with a connecting rod; (4) laying a construction operating platform; (5) paying off an upright rod in a positioning mode and installing; (6) erecting longitudinal and horizontal cross rods; (7) unloading inclined rods and erecting inclined rods on a beam bottom; (8) installing an adjustable support; (9) installing templates on the beam bottom; (10) binding beam reinforcing steel bars; (11)installing templates on the beam side; (12) installing templates on the template on a plate bottom; (13) binding plate reinforcing steel bars; and (14) pouring concrete. The construction method has the beneficial effect that a three-dimensional cross operation space is provided for each construction working procedure, the construction period can be greatly shortened, a channel is provided for concrete in-site conveying, the pouring efficiency of concrete is improved, adopted materials can be reused, and the construction method conforms to the environmentally-friendly construction requirementsof high efficacy and energy conservation.

Description

technical field [0001] The invention relates to a construction method for a large-span suspended corridor type formwork support system, which belongs to the technical field of construction engineering. Background technique [0002] In recent years, a large number of large shopping plazas and large industrial workshops have sprung up, but the conventional floor formwork support system can no longer meet the construction technical requirements of such projects. The following three aspects: 1. When constructing large-scale equipment, it can only be carried out after the floor formwork support system is dismantled, which greatly increases the construction time of key lines; Partly, the pouring task can only be completed by transporting concrete with a large tower crane, which greatly affects the efficiency of floor concrete pouring; 3. When the floor elevation of the central hall of a large public building is 20m or above, it is difficult to control the verticality of the vertic...

[0002] In recent years, a large number of large shopping plazas and large industrial workshops have sprung up, but the conventional floor formwork support system can no longer meet the construction technical requirements of such projects. The following three aspects: 1. When constructing large-scale equipment, it can only be carried out after the floor formwork support system is dismantled, which greatly increases the construction time of key lines; Partly, the pouring task can only be completed by transporting concrete with a large tower crane, which greatly affects the efficiency of floor concrete pouring; 3. When the floor elevation of the central hall of a large public building is 20m or above, it is difficult to control the verticality of the vertical pole of the floor support system , often due to the large force eccentric moment of the vertical pole, the support system deforms too much, or even collapses.
