Embodiment 1

[0018] Embodiment 1, with reference to figure 1 .

[0019] The partition wall provided by the present invention includes a wallboard 2 made of ultra-high toughness cement-based composite material, the thickness of the wallboard is 10-20 mm, and the shape of the wallboard 2 in this embodiment is lath-shaped. Under the premise of meeting the requirements of the specification, the shape and thickness of the wallboard can also be flexibly designed with other shapes and thicknesses.

[0020] The mass ratio of the components of the mortar matrix of the ultra-high toughness cement-based composite material is cement: water: fine aggregate: fly ash: silica fume: granulated blast furnace slag: metakaolin = 1: (0.27~2.2): (0~ 3): (0~6.9): (0~0.3): (0~0.55): (0~0.4), where the maximum particle size of fine aggregate is not greater than 0.55mm, fly ash, silica fume, granulated blast furnace The weight of slag and metakaolin is not zero at the same time. In addition, chopped fibers are ad...

Embodiment 2

[0024] Embodiment 2, with reference to figure 2 .

[0025] In this embodiment, the wall panels 3 are connected to form a partition wall through oblique iron pins 1; Embed the embedded part 2 for connecting with the top building.

[0026] The specific steps of partition wall construction are as follows: (1) Make the line according to the position of the partition wall in the drawing; (2) Assemble the wall panels 3 according to the installation sequence. During the installation of the wall panels, the prefabricated wall panels are required to be vertical and have a flat surface. Use a ruler to check the verticality and flatness; (3) if figure 2 As shown, the panel and the building on the top of the wall panel are fixed by embedded parts 2, and the wall panels are connected by iron pins 1; (4) Pry up the lower end of the wall panel 3 and drive in the wooden wedge 4 Tighten the wallboard and the building on top of the wallboard, and fill the gap between the wooden wedges 4 wi...

Abstract

The invention provides a non-bearing type light thin-wall damping partition wall which comprises a wall board formed by an ultrahigh toughness cement-based composite material; the mortar matrix of the ultrahigh toughness cement-based composite material comprises cement, water, fine aggregate, pulverized fuel ash, silica fume, granulated blast-furnace slag and metakaolin, and the mass ratio among the components of the mortar matrix is 1: (0.27-2.2): (0-3): (0-6.9): (0-0.3): (0-0.55): (0-0.4), wherein the maximum particle size of the fine aggregate is not larger than 0.55mm, and the weights of the pulverized fuel ash, the silica fume, the granulated blast-furnace slag and the metakaolin are not equal to 0 at the same time; furthermore, chopped fiber is added into the mortar matrix, and volume dosage of the chopped fiber is 1-3% of that of the wall board; and the slump cone expansion diameter range of the mortar matrix with the chopped fiber is 60-70mm. The non-bearing type light thin-wall damping partition wall effectively replaces the traditional wall board material, and has the advantages of being high in strength, thin in thickness, fire-resistant, impervious, good in durability, low in thermal conductivity, low-carbon, energy-saving and the like.

Description

technical field [0001] The invention belongs to the technical field of new wall materials, and relates to a method for making and assembling a non-load-bearing lightweight thin-wall shock-absorbing partition wall. Background technique [0002] At present, my country's wall materials have shown a diversified pattern, and the innovation and promotion of most building wall materials are aimed at energy saving and low carbon, such as foam concrete, lightweight lime sand bricks, etc. Although such materials have It has the characteristics of light weight and good thermal performance, but it has disadvantages such as low strength, large thickness, easy cracking, and poor durability, which largely limits its application in building walls. Contents of the invention [0003] The object of the present invention is to provide a non-load-bearing lightweight thin-wall shock-absorbing partition wall. This kind of partition wall can effectively replace traditional wall materials, and has...
