Problems solved by technology

[0003] The invention mainly solves the problem that the original autoclaved sand aerated concrete block masonry wall body is easy to leak, swell, crack, and the plaster layer on the surface is easy to hollow out and fall off, so that the wall body cannot be freely loaded, grooved, and opened. Holes, plastering and veneering bricks seriously affect the construction of the building's interior and exterior wall finishes and the technical problems of wall durability; provide a construction method for AAC block free-loading walls, which are built by masonry The free-loading wall of the AAC block has high surface strength and good waterproof effect. It can be freely loaded, slotted, opened, and plastered. The wall is not easy to crack, and the plaster layer on the surface is not easy to hollow out and fall off. Facilitate the construction of building interior and exterior wall finishes, making AAC block free-loading walls easy to maintain and durable

Embodiment 1

[0030]Embodiment 1: The AAC block free-loading wall built in this embodiment is used as the outer wall, and the construction method of the AAC block free-loading wall includes the following steps:

[0031] ①. Prefabricated concrete block 4, the concrete block 4 adopts C20 plain concrete block, the length, height, and thickness of the concrete block 4 are 100mm, 100mm, and 100mm respectively; the standard autoclaved sand aerated concrete block is produced by a special factory, and its length , height, and thickness are 600mm, 250mm, and 240mm respectively; when the blocks and concrete blocks enter the site, they are stacked according to the order of the AAC block material list, and are packed with plastic film to prevent rain. It should be noted that when the blocks are stacked, the bottom should be raised. Blocks wetted by rain should not be placed on the wall immediately, and the moisture content of the blocks on the upper wall should not be greater than 25%. According to the ...

Embodiment 2

[0047] Embodiment 2: The AAC block free-loading wall built by this embodiment is used as the inner wall, and the AAC block free-loading wall construction method, the length, height and thickness of the prefabricated concrete block 4 are respectively 100mm, 100mm, and 240mm; standard After the autoclaved sand aerated concrete blocks are pre-dried and shrunk in the stockyard, the blocks are processed according to the order of the material list, and the standard autoclaved sand aerated concrete blocks are obliquely and symmetrically cut off two rectangular parallelepiped blocks along the length direction to form Two cuboid gaps 3, the length, height, and thickness of the gaps 3 are also 100mm, 100mm, and 240mm respectively, and the two gaps are arranged diagonally and symmetrically to form the first block 1, and a gap 3 is located on the upper left of the first block 1 part, another notch 3 is located at the lower right part of the first block 1, such as image 3 shown. All the ...

Abstract

The invention relates to a construction method for an AAC block free-loading wall. The method comprises the following steps: prefabricating first blocks, second blocks and concrete blocks, wherein the first blocks and the second blocks are AAC blocks and have the same size, a cubic gap is reserved in each of the left and right sides of each first block, the two gaps are positioned in two opposite corners of each first block respectively, and the concrete blocks and the gaps have the same size; building an odd number of building bodies by using the first blocks, embedding the concrete blocks into the gaps of the first blocks while carrying out building, and building an even number of building bodies by using the second blocks; after the wall is built, immediately coating an adhesion agent, anchoring anchor bolts into the concrete blocks, fixing galvanized steel wire nets on the anchor bolt, painting polymer mortar, and carrying out leveling; marking the position of each concrete block to facilitate loading and hole-forming. The construction method has the advantages of being simple, convenient and easy in construction, simple and clear in interface blocking, low in energy and material consumption, free in wall loading, controllable in deformation and firm in structure.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for an AAC block free-loading wall. Background technique [0002] Autoclaved aerated concrete block, also known as AAC block, is a microporous block made of quartz sand, lime, cement and aluminum powder (foaming agent) through a series of production processes Air-rigid wall materials have many advantages such as light weight, easy cutting, thermal insulation, sound absorption and sound insulation, earthquake resistance and fire prevention, etc., and can meet the wall requirements of different energy-saving goals in construction projects. The strength of the block itself is not high, it is afraid of water, it will swell when it encounters water, its strength will decrease, and its shrinkage will be large, so that some common problems will be exposed in the use of autoclaved sand aerated concrete blocks. The wall of the AAC block has the common problems o...
