Embodiment Construction

[0023] A formwork-free construction method in a narrow space, comprising the following steps:

[0024] The vents on the top of the airtight outer wall of the vault building must use a square group of holes with a side length not greater than 200mm as the vents due to security requirements, and the vents cannot be directly connected to the outside world, and the vertical structure "S" bend is used to convert the lower part Long strip-shaped external ventilation openings with a width not greater than 200mm;

[0025] The "S" bend of this structure is divided into two constructions. First, the overall construction of the hexahedron airtight exterior wall structure of the building is carried out, and the hanging plate structure is under the second construction. Reserve the main ribs of the hanging slab on the roof and pre-insert the horizontal ribs on the wall, and set a post-casting hole with a lower opening of Φ150 and an upper opening of Φ200 every 1m in the thick area of ​​the ...

Abstract

The invention discloses a construction method of a narrow and small space without removing a mould. Construction of "S" bending is divided into secondary, firstly, a hexahedron closed outer wall structure of a building is constructed integrally, and secondary construction is conducted on a lower hanging plate structure; and an inner mould adopts a way of erecting a steel bar truss floor supportingplate, a formwork-replacing system is used for matching welded single head split-bolts to replace a wood mould and a supporting system thereof, angle 40x40x3 angle steel is adopted to match with rivets for anchorage connection for converting and strengthening at the interface between the floor supporting plate and a primary structure and at the 1 / 2 plate height position, an external mould still adopts a wooden mould system, but intervals of the single head split-bolts are adjusted according to intervals of floor supporting plate steel truss ribs. According to the construction method of the narrow and small space without removing the mould, construction is convenient, and the work effect is good.

Description

technical field [0001] The invention relates to a construction method in a narrow space without removing formwork. Background technique [0002] It is very inconvenient to remove the formwork in the narrow space of the bank vault building. Therefore, it is very necessary to study and find a convenient construction method without removing the formwork, which has become an important subject of research in this field. Contents of the invention [0003] The purpose of the present invention is to provide a construction method with convenient construction and good effect without removing formwork in narrow spaces. [0004] Technical solution of the present invention is: [0005] A formwork-free construction method in a narrow space is characterized in that it includes the following steps: [0006] The vents on the top of the airtight outer wall of the vault building must use a square group of holes with a side length not greater than 200mm as the vents due to security requirem...
