Problems solved by technology

The working surface is small, and the construction formwork is difficult. Anti-riot, anti-drilling and anti-theft performance must be considered. When setting up the formwork, the use of pre-embedded plastic pipes for pull bolts cannot be considered. The overall one-time pouring makes it difficult to set up and remove the formwork
The construction site is located on the basement floor, so it is extremely inconvenient to transport materials, and it is not conducive to the entry of large machinery

Embodiment

[0019] The construction method of explosion-proof and anti-drilling vertical formwork for the shear wall of the treasury in this embodiment, the specific steps of the construction method are as follows:

[0020] (1) Preliminary preparations: do a good job of technical disclosure, personnel and equipment preparation; at the same time, do a good job of working conditions and transportation preparations;

[0021] (2) Selected materials: 15mm thick bamboo plywood is used, the backing is 60×80 wooden corrugated, and the template is 200mm apart; the steel pipe is made of Φ48 double steel pipe; the tie rod is made of Φ14 secondary machining round steel;

[0022] (3) Formwork for the corridor wall: such as figure 1 and 2 As shown, the outer wall of the corridor adopts the water-stop pair of tie rods with formwork limit braces, and the distance between them is set to 500mm. Nuts, the left side pull bolts are 160 mm from the bottom surface, and the right side pull bolts are 250 mm fro...

Abstract

The invention relates to a vault shear wall anti-explosion and drilling-resistant formwork erecting construction method. The construction method comprises the following steps that (1) materials are selected; (2) ambulatory wall formworks are erected; (3) ambulatory cast-in-place slab formworks are erected; and (4) the formworks are dismounted. During formwork design, fixing inner nuts are used on the inner sides, and left split bolts and right split bolts are staggered up and down. The method has the advantages that through the vault shear wall anti-explosion and drilling-resistant formwork erecting construction method, the formwork erecting and dismounting difficulty is lowered, and thus the construction quality is well ensured.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to an explosion-proof and anti-drilling vertical formwork construction method for a shear wall of a vault. Background technique [0002] The business office building project of Zaozhuang Bank Co., Ltd. has a total construction area of ​​about 30,000 square meters. It has a frame structure with 22 floors above ground and 1 floor underground. The eaves of the building are 99.8 meters high. , 300, and 350, according to Article 3.4.6 of the "Financial Industry Standards of the People's Republic of China-Bank Treasury" (JR / T003-2000), the wall, roof, and floor of the vault are designed to be C50 commercial concrete, and the wall standards must tend to The prevention index of the main security layer near the warehouse door has anti-theft performance such as explosion-proof and anti-drilling. The underground warehouse building is designed as a corridor with a clear width of...
