Independent basic construction inner template device with cup opening smaller than 600*600 mm<2> and construction method thereof

Abstract

The invention belongs to a small-size cup opening independent basic construction method, and in particular relates to an independent basic construction inner template device with a cup opening smaller than 600*600 mm<2> and a construction method thereof. The independent basic construction inner template device comprises a basic concrete cushion layer, an outer template and a frustum cup opening inner template, and is characterized in that a bottom-sealed frustum cup opening inner template device is arranged on the top in the outer template and consists of a bottom-sealed frustum cup opening inner template, a plastic cloth layer, an inner template pull-out hook and a component for preventing the cup opening inner template from floating. The independent basic construction inner template device is rational in design and simple and practical; the inner template can be effectively prevented from floating; the forming quality of the cup opening is high; furthermore, concrete is compactly vibrated; the cup opening is formed at one time; during pouring, the concrete is prevented from entering the cup opening; manual cleaning and correction of the bottom of a cup are not needed; the cost is reduced; the working efficiency is improved; and the independent basic construction inner template device is very convenient to operate and use.

Description

technical field [0001] The invention belongs to the construction method of an independent foundation with a cup opening of a small size, and in particular relates to an internal formwork device for construction of an independent foundation with a cup opening smaller than 600mm×600mm and a construction method thereof. Background technique [0002] At present, when pouring the cup foundation smaller than 600㎜×600㎜, the customary, traditional unsealed inverted cone-shaped cup mouth inner formwork is usually used. It is to pour the foundation concrete cushion at the bottom of the foundation pit on the ground. The outer formwork is supported on the foundation concrete cushion, and the outer formwork usually adopts a stepped platform with a large bottom and a small top, and an inverted cone-shaped inner formwork with a small cup size and no bottom closure is set inside the outer formwork. The no bottom cover of the template in the cup mouth of the frustum body is for "anti-floatin...

Problems solved by technology

This method, one is a waste of labor, and the other is that the concrete around the cup mouth is not compacted and the strength is reduced.

If the size of the cup mouth is small, manual cleaning is very difficult, and even after the concrete pouring is completed, it will be manually chiseled with an electric pick, which will increase more costs and man-hours. In addition, after the concrete is poured and finally set, the inverted cone must be removed It is very difficult to form the inner cup of the table body
