Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the problem that the ring beam and the floor slab cannot vertically settle freely under the action of the structural column, and then make it crack, resulting in the weakening of its overall performance. The construction method of the rammed earth wall that can be vertically settled at the junction to solve the above problems

Embodiment 1

[0024] Embodiment 1: as Figure 1-3 As shown: the present invention adopts the addition of a specially designed reinforced concrete ring beam 5 and reinforced concrete structural column 8 in the original rammed earth wall 1 to realize the coordinated settlement of the three to avoid cracking of the rammed earth wall and improve its seismic performance. The specific construction Proceed as follows:

[0025] Step1 In the raw material of the rammed earth wall 1, according to 5%~30% of the volume ratio of the rammed earth wall 1, add the volume compressible resilient aggregate 10, and carry out the tamping of the lower rammed earth wall 1;

[0026] Step2 Reinforced concrete structural columns 8 are set in the rammed earth wall 1 of the lower floor and extend to the upper rammed earth wall 1. The vertical steel bars 9 of the reinforced concrete structural columns 8 are sleeved with sleeves 3, and the two ends of the sleeves 3 are respectively connected with the steel bars. The upp...

Embodiment 2

[0034] Embodiment 2: In this embodiment, the inner diameter of the casing 3 is 10-20 mm larger than the outer diameter of the vertical steel bar 9 of the reinforced concrete construction column 8 . The casing 3 can be made of PVC, metal, raw bamboo or other suitable materials. The thickness of foam cushion layer 7 is 10-20mm.

[0035] Such as Figure 4 As shown, it is a scene diagram of the application of the present invention in the main construction project of "Yunnan Rural Revitalization Research and Development Center", in which the casing 3 is the PVC pipe used. Cracking at the junction of structural columns.

Abstract

The invention relates to a construction method for coordinated settlement of a ring beam, a structural column and a rammed earth wall, and belongs to the technical field of construction engineering. The rammed earth wall, the reinforced concrete structural column and the reinforced concrete ring beam are included; 5%-30% of volume-compressible resilient aggregate is added to the rammed earth wall,and the rammed earth wall is tamped; a groove is formed in a column head of the reinforced concrete structural column of the rammed earth wall, a foam cushion layer is placed at the bottom of the groove, and an asphalt insulation layer is painted on the side wall of the groove; when concrete is poured in the reinforced concrete ring beam, the concrete flows into the groove and forms a protrusionon the bottom surface of the reinforced concrete ring beam, and the horizontal displacement of the reinforced concrete ring beam is limited during an earthquake; and sleeves sleeve reinforced sectionsat the overlap positions of reinforced concrete structural column vertical reinforcing steel bars and the reinforced concrete ring beam, and then concrete is poured in the reinforced concrete ring beam. The cracking of the reinforced concrete ring beam caused by the shrinkage of the rammed earth wall can be avoided, the shrinkage deformation of the rammed earth wall can be reduced, and the overall performance of the rammed earth wall can be significantly improved.

Description

technical field [0001] The invention relates to a construction method for the coordinated settlement of ring beams, structural columns and rammed earth walls, and belongs to the technical field of construction engineering. Background technique [0002] Traditional rammed earth buildings have a long history in my country, and have the advantages of using local materials, low cost, environmental friendliness, warm in winter and cool in summer. However, with the development and application of modern materials, as well as the traditional rammed earth building structure's poor strength, insufficient seismic performance, poor durability and other unfavorable factors, rammed earth buildings have gradually withdrawn from the stage of history. However, in recent years, people have paid more and more attention to the environment, as well as the popularization of green local building materials knowledge and the development of rural revitalization work, the advantages of raw earth mater...
