Problems solved by technology

It takes a lot of manpower, material resources and time to set up and remove the formwork
It takes a lot of forest resources to make wooden formwork, and the reuse rate of wooden formwork is low, which causes a waste of resources and also brings serious harm to the environment of our country
The traditional steel formwork has problems such as heavy weight, inconvenient disassembly, and high labor intensity for the operator.

Embodiment Construction

[0027] The following structures further describe the technical solutions in the embodiments of the present invention in combination with the drawings in the embodiments of the present invention.

[0028] Such as Figure 1-14 As shown, a form-free composite column of the present invention includes a concrete prefabricated side wall, a steel cage 8, and cast-in-place concrete 9. The prefabricated side wall is filled with cast-in-place concrete 9, and the cast-in-place concrete 9 is provided with a reinforcement cage 8 connected with the concrete prefabricated side wall. The concrete prefabricated block layer is formed by joining together two concrete prefabricated blocks 1 .

[0029] refer to figure 1 — Figure 4 , both are concrete prefabricated blocks 1, where figure 1 — image 3 shows a semi-square block, Figure 4 A semi-circular block is shown; stirrups are pre-embedded in the prefabricated concrete block 1, the stirrups are provided with mustache tendons 3, and the m...

Abstract

The invention discloses a mold-free laminated column and a construction method thereof. The mold-free laminated column comprises a concrete prefabricated side wall, the concrete prefabricated side wall is built by a plurality of concrete prefabricated block layers, the concrete prefabricated side wall is internally filled with cast-in-place concrete, and the cast-in-place concrete is internally provided with a reinforcement cage connected with the concrete prefabricated side wall. The construction method of the mold-free laminated column includes the following steps that (1) the column reinforcement cage is bound; (2) concrete prefabricated blocks are laid and horizontal reinforcing bars are bound and connected, and each concrete prefabricated block is laid at staggered joints; and (3) concrete is poured, and the mold-free laminated column is formed. The mold-free laminated column requires no additional mold supporting and removing operation, construction is convenient and quick, the construction period can be greatly shortened, the construction cost is saved, and industrialization can be realized.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a form-free laminated column and a construction method thereof. Background technique [0002] my country is vigorously developing prefabricated buildings. The industrialization of construction has become an inevitable trend in the development of the construction industry. It has become the mission of current construction practitioners to transform the all-in-place construction model into a factory prefabricated and assembled on-site construction model. [0003] At present, during the construction of cast-in-place concrete columns, it is generally necessary to support wooden formwork or steel formwork before pouring concrete. After the concrete reaches a certain strength, the formwork can be removed to form cast-in-place concrete columns. Formwork support and formwork removal need to consume a lot of manpower, material resources and time. It takes a lot of forest resources to...
