Embodiment 1

[0048] The rammed earth wall double-layer steel mesh sheet is applied to the wall with a thickness of 500mm.

[0049] The vertical steel bar is anchored in the girder or foundation bearing the rammed earth wall, and the anchorage length is 18d, where d is the diameter of the vertical steel bar. The diameter of the vertical steel bars is 20mm, and the distance between the surface and the surface of the rammed earth wall is 150mm. The horizontal steel bars are tied to the vertical steel bars, the diameter of the horizontal steel bars is 18mm, and the distance between the horizontal steel bars along the height direction is 800mm.

[0050] The double-layer steel mesh sheets are connected by tie bars. When the height of the new rammed earth enclosure wall is greater than 6500mm, structural measures should be strengthened and the main structure should be reliably connected, and the following requirements should be met:

[0051] The wall is connected with the main structure through...

Abstract

The invention discloses a rammed earth wall body structure of a double-layer rebar mesh sheet. The rammed earth wall body structure includes a rammed earth wall body, a main body frame beam or wall body or auxiliary structure structural beam or wall body connected with the rammed earth wall body, the rammed earth wall body is provided with a plurality of anti-crack iron wires, a vertical rebar andsymmetrical distributed double-layer horizontal rebar belts in a buried mode, and the double-layer horizontal rebar belts are connected with the vertical rebar by a steel tie in a colligation mode; the top and bottom of the vertical rebar are connected through a horizontal reinforced mortar belt; the bottom of the vertical rebar is bent and buried in a foundation of the rammed earth wall body; and the rammed earth wall body is connected with the main body frame beam or wall body or auxiliary structure structural beam or wall body by the middle of the vertical rebar through a beam tie rebar connected to the horizontal reinforced mortar belt. According to the rammed earth wall body structure, the double-layer reinforced mesh sheet is arranged in the rammed earth wall body, and overall bearing capacity and anti-seismic safety performance of the wall body are improved.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a construction technology for strengthening rammed earth walls, which can enhance the bearing capacity and anti-seismic safety performance of the rammed earth walls. Background technique [0002] Rammed earth buildings have the advantages of local materials, simple construction, low cost, outstanding thermal performance, degradable regeneration, low energy consumption and no pollution during processing. In particular, rammed earth materials have an ecological cost-effective advantage that cannot be compared with conventional energy-saving materials in rural areas. However, it is undeniable that the inherent defects of traditional rammed earth in terms of craftsmanship, construction technology, seismic performance and durability make it difficult to meet the urgent needs of improving living quality and housing safety, and also restrict its modern rammed earth appl...
