Embodiment Construction

[0028] Such as figure 1 As shown, the integrated column template 2 of this embodiment is a tubular structure printed by 3D, and its longitudinal section is as follows figure 2 As shown, its cross-section is shown as image 3 shown. The printed tubular structure consists of a tubular wall 21 and reinforcing ribs 22 .

[0029] In this embodiment, the reinforcing ribs 22 are arranged on the inner side of the tube wall 21. The reinforcing ribs 22 are continuously distributed in an annular shape and arranged circumferentially around the inner side of the tube wall 21. On the whole, the reinforcing ribs 22 are multi-channel, along the axial direction of the tube wall 21. Arranged in sequence. As another implementation manner, the reinforcing ribs are helically arranged.

[0030] The reinforcing ribs 22 can also be provided with reinforcing ribs on the outside of the tube wall 21 or both inside and outside. If a larger wall thickness is adopted, the reinforcing ribs may not be r...

Abstract

The invention discloses an integral column formwork based on 3d printing and used for concrete pouring. The integral column formwork is of a tubular structure formed through 3d printing and is composed of pipe walls and reinforcing ribs. The invention further discloses a column pouring method. The column pouring method comprises the steps that a column reinforcement cage is bound; the integral column formwork is arranged on the periphery of the column reinforcement cage; and after the integral column formwork is fixed properly, concrete is poured into the integral column formwork, and the poured concrete, the reinforcement cage and the integral formwork are combined into a whole to form a reinforced concrete column. Cement-based mortar is adopted by the column formwork, the column formwork is formed through 3d printing, wood materials are saved, and environment protection is facilitated. Processing and on-site installation processes of wooden formworks are omitted, and the procedures of dismounting and cleaning the formworks are omitted. The column poured through the integral formwork is good in integrity, firm, reliable, low in cost, convenient and easy to construct, and high in construction speed.

Description

technical field [0001] The invention relates to the field of building engineering construction, in particular to an integrated formwork for pouring reinforced concrete columns and a column pouring method using the integrated formwork. Background technique [0002] At present, the columns in construction projects generally use wooden formwork when pouring concrete. Wooden formwork consumes a lot of wood, which is very unfavorable to the environment, and wooden formwork consumes man-hours during construction, which is one of the most costly links in construction engineering. [0003] There are also metal or other material formworks, such as an existing adjustable column steel formwork. A columnar body formed by splicing several templates; the edge of the template is provided with a flange for splicing between the templates; the template is a planar template, and several planar templates are spliced ​​in sequence to form a columnar body with a square cross section. [0004] An...
