A kind of l-shaped formwork for tamping

Abstract

The invention discloses an L-shaped formwork for tamping, which comprises Ai boards, Ao boards, Bi boards, Bo boards, two DC end boards and two DD end boards, two diagonal braces and multiple wall-through screw rods ; Among them, the Ai board, Ao board, Bi board, Bo board, DC end board and DD end board are plate-shaped bodies fixed together by steel frames and baffles; Ai board, Ao board, Bi board, Bo board The plate forms a closed L-shaped closed section with two DC end plates or two DD end plates; the invention can ram the L-shaped wall at one time, and is suitable for the ramming construction at the corner of the gable wall and the front and rear walls, overcoming the traditional The many vertical joints caused by the formwork lead to poor integrity and poor durability of the wall, and it is easy to install and disassemble. At the same time, it can effectively solve the problem of uneven surface of the wall rammed by the traditional rammed earth formwork. Good rigidity, can effectively resist the impact of tamping. At the same time, the construction precision is high, which can meet the two conventional construction types of modular construction and flexible size adjustment.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to an L-shaped formwork for ramming, which is suitable for ramming construction at the corners of gable walls and front and rear walls. Background technique [0002] Rammed earth is a traditional house construction technology with the longest history and widest application in rural areas in my country. It is mainly used in the construction of load-bearing walls and enclosure walls of houses. It has the advantages of local materials, simple construction, low cost, low energy consumption and low pollution. According to the survey and statistics of the Ministry of Housing and Urban-Rural Development from 2010 to 2011, at least 50 million people in China still live in various forms of traditional rammed earth dwellings. However, the inherent defects of traditional rammed earth in terms of mechanics and durability make it difficult for traditional rammed earth dwellings ...

AI Technical Summary

Problems solved by technology

[0007] However, the above-mentioned traditional rammed earth wall formwork has the following disadvantages: although the first type of formwork system is simple to operate, due to the limitation of its own structure, the formwork size cannot be enlarged, resulting in the small height and length of each completed wall , affecting the integrity of the wall, and because it is made of pure wood, the board is easily deformed and damaged

The second type of formwork uses round logs, so the surface of the rammed wall is uneven and extremely uneven

At the same time, because there is no fixed end form, the wall size error is relatively large during tamping

Moreover, these two types of templates also have a common disadvantage, that is, only one-line walls can be rammed, and it is impossible to solve the one-time ramming of adjacent walls, so that there will be obvious vertical joints between adjacent walls, which will affect the stability of the house. have a large impact on the whole (such as figure 1 , figure 2 shown)

In addition, the introduction of pneumatic rammers has higher requirements on the impact resistance of ramming formwork, and traditional bamboo and wood formwork, and even steel formwork for concrete pouring cannot meet this requirement well
