U-shaped anti-changing column and chute template system for rammed earth walls

Abstract

The invention discloses a U-shaped anti-changing column and chute template system for rammed earth walls, which can be used for special template for the construction of the linear rammer body and theL-shaped wall body. The supporting system mainly comprises three aspects: a wood-shaped smooth mold plate, a long-length U-shaped anti-changing column suitable for layer-by-layer compaction, and an adjustable high-strength section steel triangular support frame. The wooden mold plate is inserted into the standard fixed-type long-length U-shaped anti-variable column to form a whole, and the supportside is supported by the adjustable high-strength section steel triangular support frame., and mainly comprises a vertical rod, an inclined rod and a horizontal sliding rod. The two sides of the wallbody are symmetrically arranged to be supported to ensure the stable and follow layer-by-layer support and layer-by-layer compaction, the steel braced tripod square steel tube members are connected with the U-shaped anti-changing columns by pin bolts, and two U-shaped anti-changinge columns at L-shaped corner of rammed earth wall are welded together to ensure that the lateral pressure meets the strength requirements. The U-shaped anti-changing column and chute template system not only can satisfy the linear rammer, but also can realize the dynamic compaction of the L-type wall body with highquality.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a U-shaped anti-deformation column and chute formwork system for rammed earth walls. Background technique [0002] Traditional raw earth houses have a long history in our country. They have the characteristics of local materials, simple construction, low cost, warm in winter and cool in summer, and environmental friendliness. Due to the influence of unfavorable factors such as low strength, poor durability, etc., it is gradually fading out of the historical stage in the Northwest and even the whole country. However, due to factors such as environmental pollution, shortage of materials in mountainous areas, and people's emphasis on traditional culture, the National Development and Reform Commission, the Ministry of Housing and Urban-Rural Development, and various localities have successively issued relevant policies to protect rammed earth buildings, and various construction ...

Problems solved by technology

For adobe houses, the experience is to increase its strength by adding auxiliary materials such as wheat straw to the adobe, but it still cannot meet the requirements. For rammed earth walls, it is very important that the formwork of rammed earth walls cannot meet the strength requirements of rammed earth walls. Most areas still adopt the traditional method of wooden wallboards, clips, and hoops, and some areas even adopt the traditional method of building rammed earth. The earth walls rammed by the above two methods are not suitable for placement and turnover of formwork materials. The lack of proper displacement limiting measures often leads to uneven rammed earth, severe damage to strength and earthquake resistance such as mold expansion and inclination, and the formwork at corners is not easy to support, the position of door and window openings is not well considered, and the rammed earth wall is narrow. The lower width affects the appearance. When the formwork is dismantled, the wall surface is uneven, and vertical gaps are formed on adjacent walls. The height is limited. No matter whether the rafters hit the wall or the board hits the wall, it is necessary to move the wall panels, which also leads to a great reduction in its strength. Based on the above Due to various unfavorable factors, inventing a high-quality and widely practicable rammed earth wall formwork has become the top priority to improve the current situation of rammed earth walls
