T-shaped formwork for ramming

Abstract

The invention discloses a T-shaped formwork for ramming. The T-shaped formwork comprises two Ai plates, an Ao plate, two Bi plates, a Bo plate, three DC end plates, three DD end plates and multiple oppositely-pulling screws, each of the Ai plates, the Ao plate, the Bi plates, the Bo plate, the DC end plates and the DD end plates is a platy body formed by fixing a steel frame and a retaining plate together, and multiple screw holes for allowing the oppositely-pulling screws to penetrate are formed in each of the upper edge and the lower edge when each retaining plate is in a vertical state. By the T-shaped formwork, a T-shaped corner wall can be rammed in one step; the T-shaped formwork is suitable for ramming construction of gable wall corners and convenient to mount and demount, the defects of low integrity and low durability of a wall due to many vertical joints caused by a conventional formwork are overcome, and the problem of unevenness of the surface of the wall rammed by a conventional ramming formwork can be solved effectively. The T-shaped formwork is high in rigidity, thereby being capable of effectively resisting ramming impact force. In addition, the T-shaped formwork is high in construction accuracy and can meet requirements of two conventional construction types including construction according to formwork number and flexible size adjusting.

Description

Technical field [0001] The invention belongs to the technical field of construction, and particularly relates to a T-shaped template for ramming, which is suitable for the construction of the gable corners of a rammed earth wall. Background technique [0002] Rammed earth is the oldest and most widely used traditional house construction technology in rural my country. It is mainly used for the construction of load-bearing walls and enclosures of houses. It has the advantages of being able to obtain local materials, easy construction, low cost, low energy consumption and low pollution. According to the 2010-2011 survey by the Ministry of Housing and Urban-Rural Development, there are currently at least 50 million people in China living in various forms of traditional rammed earth dwellings. However, the inherent shortcomings of traditional rammed earth in terms of mechanics and durability have made it difficult for traditional rammed earth houses to meet the urgent needs of farmer...

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
