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 the...

Abstract

The invention particularly discloses a free standing brick setting aseismatic cave dwelling and a construction method thereof. The cave dwelling comprises brick foundations, foundation ring beams, brick setting walls, upper ring beams, arch roofs, constructional columns, covering soil and a waterproof protection layer. According to the construction method, the brick foundations are built at first, and the foundation ring beams are poured on the brick foundations; then the brick setting walls are vertically built on the foundation ring beams, and the constructional columns are poured at the two ends of the brick setting walls and in the middles of the brick setting walls; afterwards, the upper ring beams are poured on the upper portions of the brick setting walls, and the arch roofs are built on the upper ring beams; and finally the tops of the arch roofs are covered with the covering soil and rammed, the waterproof protection layer is poured on the upper portion of the covering soil at the same time, and the cave dwelling is obtained. The high adhesive performance of viscous mortar and raw cob bricks is utilized, and the walls and the arch roofs of the whole cave dwelling are constrained by a frame composed of the constructional columns and the ring beams, so that the integrality and anti-collapse performance of the caved dwelling are improved; and compared with traditional cave dwellings, large earth rammed cave supports with the lateral load resistance are not needed, so that the construction work amount of the cave dwelling is greatly reduced.

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...
