A quick disassembly formwork for cast-in-place subgrade of foam light soil

Abstract

The invention relates to a quick disassembly and assembly formwork for foam lightweight soil cast-in-place subgrade, which includes four formwork panels connected at the first place, the formwork panels include two long formworks and two short formworks, and the two ends of the long formwork are vertically The direction array is provided with a number of abutment rollers, and the two ends of the short formwork are vertically provided with fixed grooves for the abutment rollers to be inserted. The width of the fixed grooves is larger than the diameter of the abutment rollers. On the long formwork, the long formwork is provided with a driving member that drives adjacent abutting rollers to slide relative to each other and fixes them. During splicing, the short formwork is fixed at the end of the long formwork under the limit of the abutting roller, so as to realize the connection between the two short formworks and the two long formworks. The fixing of the short formwork is not only very convenient for disassembly and installation, but also does not need to occupy additional space, saves the occupied space, and can adapt to the construction needs of different occasions.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a quick disassembly and assembly template for foam light soil cast-in-place roadbed. Background technique [0002] Nowadays, a large number of infrastructure projects are being constructed, especially highways and municipal engineering roadbed construction, which require a lot of fillers, while traditional roadbed fillers are basically soil. In this way, a large amount of cultivated land needs to be occupied as a borrow ground, and the cultivated land in our country is getting less and less, and the protection of cultivated land has become the consensus of all sectors of society. Foam lightweight soil is a new type of filler that appears in this situation. Its principle is to mix and foam cement, fly ash, water, and foaming agent to form a lightweight concrete with a certain porosity; It is poured on-site, and the formwork is removed after reaching a certain strength t...

Problems solved by technology

[0004] Using the above support structure, although the formwork panel can be quickly fixed, it is necessary to set up diagonal braces and fix the formwork on the outside of the formwork panel, and a certain space needs to be left outside the formwork panel. When some construction sites are relatively narrow, It is difficult to install the fixed formwork and the diagonal braces, so that the construction of the fixed formwork cannot be realized, and the adaptability is poor. Therefore, it is very important to need a quick disassembly formwork specially applied to the foam light soil cast-in-place subgrade
