Problems solved by technology

[0002] The current building partition panels are generally made of bricks, which leads to a longer construction period and heavier walls, which increases the load-bearing level of the building design and further increases the cost.
The use of hollow partition wall panels, although the construction period is fast, the weight is lighter, and the sound insulation and heat insulation effects are better, but there are the following disadvantages: slow molding, unsatisfactory demoulding, poor tongue-and-groove structure, installation and construction Inconvenient, it is difficult to guarantee the quality of the wall after installation, and it is easy to crack and slit

Abstract

The invention discloses a constructional partition plate and a preparation method thereof. The partition plate is a hollow plate, the tongue-and-groove is composed of a dovetail tenon and a dovetail groove, the tenon and the groove interlock with each other, and the groove depth is 20 mm. The partition plate is composed of the following components in parts by weight: 15 to 18 parts of cement, 25 to 30 parts of fly ash, 45 to 55 parts of building slag powder, 1 to 2 parts of water reducer, 1 to 2 parts of early strength agent, 2 to 3 parts of waterproof agent, and 2 to 4 parts of demoulding agent. The partition plate has a high compression resistant strength and low surface density, thus the floor bearing is reduced, furthermore, the thermal coefficient of the partition plate is low, and the air soundproof effect of the partition plate is very good, so the partition plate also has a good thermal insulation and soundproof effect.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a building partition board and a preparation method thereof. Background technique [0002] The current building partition wall panels are generally made of bricks, which leads to a longer construction period and heavier walls, which increases the load-bearing level of the building design and further increases the cost. The use of hollow partition wall panels, although the construction period is fast, the weight is lighter, and the sound insulation and heat insulation effects are better, but there are the following disadvantages: slow molding, unsatisfactory demoulding, poor tongue-and-groove structure, installation and construction Inconvenient, it is difficult to guarantee the quality of the wall after installation, and it is easy to crack and slit. Therefore, it is necessary to further seek a more ideal building partition board to become a reality. Contents of t...
