Problems solved by technology

[0002] As we all know, the quality of masonry is related to the quality of the wall. With the continuous promotion of high-quality and high-precision blocks of autoclaved aerated concrete and the continuous improvement of the accuracy and quality of the main structure of the building, the walls of the traditional masonry process It is very easy to have problems such as wall hollowing and cracking, which is not conducive to the overall improvement of building quality, so it is urgent to propose corresponding special masonry plans

Embodiment 1

[0020] see figure 1 , a method for dry-laying high-precision block grout, the specific steps are as follows:

[0021] 1) High-precision blocks are used to control the precision of the masonry. The allowable deviation of the size of the high-precision blocks is: length -2~0mm, width -1~1mm, height -1~1mm;

[0022] 2) Use a special adhesive with good workability, water retention, and fluidity for dry construction masonry. Before masonry, it is not necessary to spray water on the high-precision blocks, and strictly control the age of the upper wall to 28 More than 10 days, the moisture content is less than 15%;

[0023] 3) Arrange the blocks in advance before masonry, from top to bottom, and reserve a 20mm top joint at the top to replace the inclined roof brick masonry of the traditional masonry process, and the thickness of the mortar joint is controlled at 3mm;

[0024] 4) 14 days after the masonry is completed, use expansive cement mortar to grout the reserved top joints;

Abstract

The invention discloses a grout dry building method for high-precision building blocks. The method includes the specific steps that the high-precision building blocks are adopted so that the precision of brickwork can be controlled; a special adhesive agent is adopted for dry construction building, the wall application duration is strictly controlled to be over 28 days, and the moisture content is lower 15%; the blocks are arranged from top to bottom in advance before building, a preserved top joint being 20-30 mm is reserved on the top, and the thickness of each mortar joint is controlled to be 3-5 mm; expansive cement mortar is poured into the reserved top joint 14-18 days after building is completed; L-shaped iron pieces are utilized for connecting the mortar joints; and the high-precision building blocks are cut with a cutting bench saw. According to the method, the special adhesive agent is adopted for dry construction, neither the traditional building technology is largely changed, nor the cost for a wall is increased, and the problems of wall cracking, plumping up and the like can be effectively solved; and meanwhile the precision and appearance effect of the wall are improved, convenience is brought to users to the greatest extent, and the production efficiency and the quality of the brickwork are improved.

Description

technical field [0001] The invention relates to the technical field of block masonry, in particular to a method for high-precision block grout dry masonry. Background technique [0002] As we all know, the quality of masonry is related to the quality of the wall. With the continuous promotion of high-quality and high-precision blocks of autoclaved aerated concrete and the continuous improvement of the accuracy and quality of the main structure of the building, the walls of the traditional masonry process It is extremely prone to problems such as wall hollowing and cracking, which is not conducive to the overall improvement of building quality. Therefore, it is urgent to propose corresponding special masonry schemes. Contents of the invention [0003] The purpose of the present invention is to provide a method for dry-laying of high-precision blocks with grout that can effectively reduce wall cracking and hollowing, so as to solve the problems raised in the above-mentioned ...
