Embodiment 1

[0029] See Figure 1-2 , the metal connector used to improve the structural integrity of the rammed earth wall, the metal connector includes a group of shear units 1, each group of shear units consists of a steel plate 1-1 located in the middle, and a plurality of upper anti-corrosion plates welded vertically to the upper end of the steel plate. The shear steel column 1-2 is composed of a plurality of lower shear steel columns 1-3 vertically welded to the lower end of the steel plate, the shape of the steel plate, the number of the upper shear steel column, the number of the lower shear steel column, the upper shear steel column The arrangement of the columns and the arrangement of the lower shear steel columns are not restricted. The groups of shear units form an integrated connection structure through the connecting steel pieces 2 welded between the steel plates, and are L-shaped (also called L-shaped) in the horizontal direction.

Embodiment 2

[0039] See Figure 5-6 , the metal connectors in this embodiment include the shear units described in the first embodiment above and the connecting steel parts arranged between the shear units. The difference from the first embodiment is that the array of shear units is welded The connecting steel pieces form an integrated connection structure, and it is T-shaped in the horizontal direction.

[0040] In the metal connector structure of the second embodiment, the shape of the steel plate, the number of the shear steel columns and the preferred arrangement of the shear steel columns are the same as those of the first embodiment, and will not be repeated here.

[0041] In the metal connector structure of the second embodiment, the preferred structure of the upper shear steel column and the lower shear steel column and the preferred structure of the connecting steel parts are the same as those of the first embodiment, and will not be repeated here.

Abstract

The invention provides a metal connector for improving the integrity of a rammed-earth wall structure and the rammed-earth wall structure. The metal connector comprises a plurality of groups of shear resisting units, wherein each group of shear resisting unit is composed of a steel plate, multiple upper-portion shear resisting steel columns and multiple lower-portion shear resisting steel columns, the multiple groups of shear resisting units form an integral connecting structure through connecting steel pieces welded among the steel plates and are L-shaped or T-shaped in the horizontal direction. The rammed-earth wall structure comprises a rammed-earth wall body, wherein the T-shaped metal connector is arranged at the T-shaped longitudinal and transverse wall connecting position of the rammed-earth wall body and located at the layering position of a rammed-earth layer. The upper-portion shear resisting steel columns on each metal connector are inserted into upper-layer rammed earth at the corresponding position, and the lower-portion shear resisting steel columns on each metal connector are inserted into lower-layer rammed earth. The metal connector can effectively improve the integrity and horizonal shear resistance of the rammed-earth wall structure, and the rammed-earth wall structure has good integrity and shear resistance.

Description

technical field [0001] The invention belongs to the field of building wall structures, in particular to a metal connector for improving the structural integrity of a rammed earth wall and a rammed earth wall structure using the metal connector. Background technique [0002] As one of the main forms of traditional earth architecture, houses with rammed earth walls are widely used in the western region of my country. They have distinctive local and national characteristics, and are full of strong local history and cultural atmosphere. Houses with rammed earth walls are widely welcomed because of the advantages of convenient materials, low cost, energy saving, thermal insulation, simple process, and environmental friendliness. However, the rammed earth wall structure has disadvantages such as poor integrity, low horizontal shear resistance and poor earthquake resistance during use, especially the four corners of the house with the rammed earth wall structure and the junction of...
