Embodiment Construction

[0047] see image 3 As shown, a construction method of using foamed concrete lightweight material to fill the traditional empty bucket wall, the steps are as follows:

[0048] ① Hole in the wall

[0049] see figure 2 As shown, taking the empty bucket wall of the full-bucket sleepless masonry method as an example, a row of bricks is taken every 40cm from bottom to top on the wall, and each row takes 3m as a step to open holes. The horizontal distance between adjacent holes in the direction is 1.5m.

[0050] ②, preparation of foamed concrete lightweight material

[0051] a. Preparation of construction materials

[0052] (1) Cement: The amount used for a single preparation is 20kg, and the general-purpose Portland cement with a strength grade of 42.5 should be used, which should meet the requirements of "General-purpose Portland Cement" GB175-2007.

[0053] (2) Foaming agent: The amount used in a single preparation for construction is 4kg (after dilution), and a foaming age...

Abstract

The invention provides a foamed concrete light material and a construction method for filling a traditional rowlock wall and relates to the technical field of building construction. During construction, raw materials for one-time preparation comprise components in mixed proportion as follows: 20 kg of cement, 10 kg of water, 4 kg of a diluted foaming agent and 145 g of coal ash. The construction method for filling the traditional rowlock wall with the foamed concrete light material comprises steps as follows: wall holing, preparation of the foamed concrete light material, cast in place, support outside the wall, maintenance and the like. The foamed concrete is poured into the rowlock wall, so that thermal insulation properties of the traditional rowlock wall can be remarkably improved, and overall stability of the traditional rowlock wall is enhanced; furthermore, the foamed concrete has the distinguishing characteristics of being light and the like when compared with traditional stone concrete, therefore, the rowlock wall can adapt to more architectural entities and further has good fireproof and soundproof properties.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a lightweight foamed concrete material and a construction method for filling a traditional empty bucket wall. Background technique [0002] The hollow wall is a hollow wall made of bricks side by side or flat and side by side. It has the advantages of low material consumption, light weight, good heat insulation and sound insulation performance, and is suitable for load-bearing walls or frame buildings of 1-3 storey civil buildings. The empty bucket wall is a traditional wall in China, which is widely used to build residential houses and temples, and is widely used in the Yangtze River Basin and Southwest China. [0003] There are two types of masonry methods for empty bucket walls: sleeping empty bucket wall and sleepless empty bucket wall (see picture). The side bricks are called bucket bricks, and the flat bricks are called sleeping bricks. Please refer to figu...
