Combined type ramming form board system

Abstract

The invention discloses a combined type ramming form board system. The combined type ramming form board system comprises two Ai boards, an Ao board, two Bi boards, a Bo board, three DC end boards, three DD end boards and a plurality of split screws, wherein the Ai boards, the AO board, the Bi boards, the Bo board, the DC end boards and the DD end boards are board bodies formed by fixing steel frames and baffles together; parts of the Ai boards, the Ao board, the Bi boards, the Bo board, the DC end boards and the DD boards are spliced to form an I-shaped form board, an L-shaped form board or a T-shaped form board. The combined type rammed form board system has the advantages that the system is flexible to assemble, different combined form boards such as the T-shaped form board, the L-shaped form board and the I-shaped form board can be achieved by different forms of splicing, and a wall completed by the form boards is high in integrity; the form boards are good in rigidity and capable of effectively resisting ramming impacts; meanwhile, the form boards are high in construction precision and capable of satisfying the requirements of two conventional construction types such as construction performed according to modulus and construction flexible in size adjustment.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a combined rammed formwork system, which is suitable for the construction of rammed earth 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 to meet the urgent needs of farmers ...

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
