Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a disassembly-free template structure for pouring a building wall. Background Art

[0002] At present, in the process of reinforced concrete construction of building projects, it is common to install formwork on the front and rear sides of the location where the wall needs to be built, and then pour concrete between the two formworks; after the concrete solidifies, the formwork is removed, and thermal insulation materials and fireproof materials are attached to the outside of the wall, and finally a finishing mortar layer is applied; if this method is used for wall construction, it is necessary to install the formwork first, and after the concrete is poured and solidified, the formwork is removed, and then the thermal insulation and fireproof materials are attached. There are many processes, the construction is difficult, and the wall construction efficiency is low.

[0003] In order to solve the above problems, Chinese patent document No. CN220365294U disclosed a formwork-free building formwork on January 19, 2024, which belongs to the field of building technology, including a first formwork-free building formwork and a second formwork-free building formwork, the first formwork-free building formwork and the second formwork-free building formwork are horizontally aligned and symmetrically placed with each other, and a plurality of connecting support components are threadedly connected in sequence between the first formwork-free building formwork and the second formwork-free building formwork, and the number of each connecting support component is eight. Through the combination design of the first formwork-free building formwork, the second formwork-free building formwork and each group of connecting support components, a formwork-free building formwork is formed which is easy to assemble and the length and height of the formwork can be freely inserted and extended. The two formworks of this formwork-free building formwork can be bonded together with the concrete poured in the building, and there is no need to fold the formwork after pouring. There are fewer processes, less construction difficulty, and higher wall construction efficiency.
