However, at present, there is no construction method of formwork support system that meets the force transmission characteristics of this structure at home and abroad. Usually, the construction method of ordinary beam-slab formwork support system is used, which not only consumes a lot of materials, but also has a long construction period, and the deformation value of the formwork support system is often too large. , and even collapse accidents

Embodiment 1

[0028] like Figure 1 ~ Figure 2 As shown, the construction method of the membrane shell ribbed formwork support system of the present invention takes the following steps:

[0029] (1) Positioning and setting out: release the vertical and horizontal center coordinate network 1 of the dense rib of the floor on the pole foundation 16;

[0030] (2) Set up poles: erect poles 2 at the cross node center of the vertical and horizontal center coordinate network 1 of the dense ribs of the floor;

[0031] (3) Set up the horizontal bar: pop up the horizontal line on the vertical bar 2 according to the 3 steps of the horizontal bar, and then set up the horizontal bar 3, and make a reliable connection between the horizontal bar 3 and the intersection of the shear wall 4 and the frame column 5;

[0032] (4) Setting up scissors braces: set up vertical continuous scissors braces 8 on the vertical centerlines 6 between each row of frame columns and the vertical centerlines 7 of the transverse...

Abstract

The invention belongs to the technical field of building engineering, and particularly relates to a construction method of a membrane shell ribbed floor formwork supporting system. The construction method includes steps: (1) positioning and drawing lines; (2) erecting vertical rods; (3) erecting horizontal rods; (4) erecting a diagonal bracing; (5) pouring a shear wall and frame column concrete; (6) mounting an adjustable bracket; (7) mounting main ledges; (8) mounting secondary ledges; (9) placing a panel; (10) binding reinforcing steel bars of ribs and concealed frame beams; (11) mounting a membrane shell; (12) binding reinforcing steel bars of cast-in-place plates; and (13) concreting a membrane shell floor. The construction method has the advantages that characteristics of construction force transfer of the membrane shell ribbed floor are met, axial forces of the vertical rods are balanced and consistent, a stress state is safe and reliable, a construction space is large, the vertical rods are saved by five ninths, the floor construction period is halved, and requirements of high-efficiency, energy-saving and green construction are met.

Description

technical field [0001] The invention relates to a construction method for a formwork support system of a membrane shell densely ribbed floor, which belongs to the technical field of construction engineering. Background technique [0002] In recent years, in the design of large-space buildings such as shopping plazas, underground garages, and shared halls, membrane shell and ribbed floor structures are often used to meet the functional requirements of large spaces. However, at present, there is no construction method of formwork support system that meets the force transmission characteristics of this structure at home and abroad. Usually, the construction method of ordinary beam-slab formwork support system is used, which not only consumes a lot of materials, but also has a long construction period, and the deformation value of the formwork support system is often too large. , and even collapse accidents may occur. Contents of the invention [0003] The technical problem t...
