Embodiment 1

[0024] refer to figure 1 , the present invention provides a kind of free-standing brick masonry earthquake-resistant cave dwelling, comprising brick foundation 1, foundation ring beam 2, brick masonry wall body 3, upper ring beam 4, arched roof 5, structural column 6, covering soil 7 and waterproof Protective layer 8; the brick foundation 1 is two brick foundations arranged in parallel, the upper part of the brick foundation 1 is provided with a foundation ring beam 2, and the upper part of the foundation ring beam 2 corresponds to the two sides of the brick foundation 1, and respectively vertically arranged brick masonry walls 3. The upper end of the brick wall 3 is provided with an upper ring beam 4, and the two ends and the middle of the brick wall 3 are respectively vertically provided with structural columns 6, and the lower ends of the structural columns 6 are respectively connected with the foundation ring beam 2, and the structural columns The upper ends of 6 are respe...

Embodiment 2

[0029] Step 1, using viscous fiber mortar and brick blocks to build three brick foundations in parallel, and pouring reinforced concrete foundation ring beams on the brick foundations;

[0030] Step 2, using viscous fiber mortar and raw earth bricks to vertically build brick masonry walls on the foundation ring beam corresponding to the brick foundation, and at the two ends and the middle of the brick masonry walls Concrete is poured for each structural column;

[0031] Step 3, pouring an upper ring beam on the upper part of the brick masonry wall, and building a brick arch roof on the upper ring beam;

[0032] Step 4, finally covering and ramming the top of the brick arch roof of the cave dwelling, and pouring concrete on the upper part of the covering soil to form a waterproof protective layer.

[0033] in,

[0034] In step 1, the raw material components of the viscous fiber mortar include: cement, fly ash, sand, redispersible latex powder, hydroxypropyl methylcellulose an...

Embodiment 3

[0039]The viscous fiber mortar in embodiment 1 or 2 is carried out mechanical performance test, specifically as follows:

[0040] A cube test block of viscous fiber mortar was made by using a standard test mold of 70.7mm×70.7mm×70.7mm, and it was cured in a natural state (room temperature) for 30 days (the first 7 days were watered and cured), and the cubic compressive strength test was carried out. The test results show that the average compressive strength of the viscous fiber mortar test block is 21.7MPa.

[0041] A 40mm×40mm×4mm mold was used to make a tensile test block on the raw earth brick block, and it was cured for 30 days according to the standard curing method (the temperature in the curing room was 20±3 degrees, and the humidity was above 90%), and a direct tensile test was carried out. The results show that: the average uniaxial tensile strength of the raw earth brick block specimens built with viscous fiber mortar is 0.77MPa, and the failure surface occurs in th...

Abstract

The invention specifically discloses an independent brick masonry anti-seismic cave, comprising a brick foundation, a foundation ring beam, a brick masonry wall, an upper ring beam, an arched roof, a structural column, an earth cover and a waterproof protective layer; and its construction Method: firstly build brick foundation, and pour foundation ring beam on the brick foundation; then build brick masonry wall vertically on the foundation ring beam, and pour structural columns at both ends and middle of the brick masonry wall; Then, the upper ring beam is poured on the upper part of the brick wall, and the arched roof is built on the upper ring beam; finally, the top of the arched roof is covered with soil and rammed, and a waterproof protective layer is poured on the upper part of the covered soil. Serve. The invention utilizes the high bonding performance of viscous mortar and raw soil bricks, and the frame formed by the structural columns and the ring beams to constrain the walls and the arched roof of the entire cave, thereby enhancing the integrity and anti-collapse performance of the cave. Compared with traditional cave dwellings, there is no need to ram the side of a large-scale rammed earth kiln with resistance to lateral force, which greatly reduces the amount of engineering for the construction of cave dwellings.

Description

technical field [0001] The invention relates to the field of building structures, in particular to an independent brick masonry anti-seismic cave dwelling and a construction method thereof. Background technique [0002] The unique architectural structure of cave dwellings not only reflects the different regional characteristics and cultural traditions of different places, but also is warm in winter and cool in summer, healthy and comfortable, effectively reducing energy consumption and carbon emissions in terms of indoor heat preservation and cooling, and is an ecological building. At present, brick masonry cave dwellings are still widely used in some provinces in Northwest my country, but the existing ordinary brick masonry independent cave dwelling structure has weak bonding force between brick blocks, weak cave dwelling integrity, easy collapse, and poor seismic performance Defects. Contents of the invention [0003] Aiming at the problems existing in the prior art, the...
