Combination building method for brick masonry comprising sliding layer

Abstract

The invention discloses a combination building method for brick masonry comprising a sliding layer. The combination building method comprises the following steps that (1) the masonry on the lower portion of a horizontal mortar joint is built firstly, or concrete is poured according to the need, and the smoothness of the surface of the concrete needs to meet the requirement; (2) special felt, mortar and the masonry are sequentially laid on the surface of the concrete, and the masonry is continuously laid; and (3) the mortar is laid on the special felt, and when cast-in-place concrete is on theupper portion of the special felt, the mortar is not laid any more. By utilizing the flexible deformation function of the special felt, the unique structural form of the masonry and the special building method, the masonry freely stretches out and draws back under ambient environment temperature change, the masonry is prevented from being cracked, masonry cracking caused by accumulated deformationdifference generated by different expansion coefficients of the masonry combined by building blocks of different materials can also be eliminated, accumulated deformation generated by contraction ofthe building blocks which do not reach the age can further be counteracted, a wall is prevented from generating cracks, and the bearing capacity and other functions of the masonry are not affected.

Description

technical field [0001] The invention belongs to the field of masonry engineering, in particular to a brick masonry assembly method including a sliding layer. Background technique [0002] Brick masonry is widely used in construction engineering, but the cracking problem of brick masonry has been perplexing the vast number of practitioners in the engineering field. Under normal use conditions, the main factors causing cracking of brick masonry are uneven settlement, thermal expansion and contraction under the action of temperature difference (including single-material block walls and walls made of blocks of different materials), The block itself shrinks and deforms (the upper wall is built before the age is reached). For uneven settlement cracks, as long as the factors that cause uneven settlement are eliminated in advance, cracks can be avoided. The remedial measures after cracks are often to eliminate the factors that cause uneven settlement, and then repair the cracks. F...

Problems solved by technology

For the cracks generated by the single-material block wall under the action of temperature difference, the preventive measures are often to isolate the masonry from external factors to keep it in a relatively constant temperature environment, but it is often difficult to use this method in some engineering parts ( Such as the lower low wall of the light steel structure factory building envelope), so cracks are often unavoidable, and only follow-up repair measures can be taken, resulting in an increase in engineering costs and waste of materials; for walls built with blocks of different materials Under the action of temperature difference, due to the difference in the expansion coefficient of the blocks themselves, the cracks caused by the cumulative deformation difference are often prevented. The preventive measures are often to prohibit the mixing of blocks of different materials, or to lay anti-cracking nets on the surface of the wall where the blocks of different materials are combined. , and then plastered and covered, it is tantamount to a strategy of "blocking", but lacks the link of "sparse", so it cannot completely prevent cracking

For the cracks that are built on the wall before the age of the block, and then accumulated deformation due to self-shrinkage within the age, the preventive measure is to build it after reaching the age, otherwise only repair measures can be used. For the cracks caused by misoperation Cracked walls, follow-up repairs will also result in increased engineering costs and waste of materials

Cracks in the outer wall may also cause problems such as wall leakage
