Problems solved by technology

At the same time, the thickness of the wall is increased, the cost of construction is also increased, and the efficiency of construction is reduced.
Part of the blocks are formed by pressing, limited by the capacity of the equipment, which cannot meet the production of larger blocks
The popularization and use of lightweight pure gypsum blocks is also limited due to the phenomenon that they are prone to mold due to moisture

Embodiment Construction

[0012] Embodiment of the present invention is illustrated below in conjunction with accompanying drawing:

[0013] The shape of the wallboard is a rectangular slab with a length of 666mm, a width of 500mm and a thickness of 100mm. On the four side surfaces of the wallboard 1, grooves 2 or ribs 3 are respectively processed, and the grooves 2 and the ribs 3 are oppositely arranged, that is, one side surface is processed with a groove 2, and the corresponding other side The surface is processed with ribs 3 . The thickness of the wall panels can be 120mm or 150mm as required. The wall panel used at the bottom beam of the wall or the lintel of the door and window can be a long rectangular column, such as 2000mm in length, 200mm in width, and 100mm in the rear.

[0014] The material composition of making wallboard 1 is by weight ratio: sludge ceramsite 70%, cement 15%, gypsum 15%; The weight of water accounts for 75% of cement plus gypsum weight; Yes, high iron powder 1‰, cellulo...

Abstract

The invention relates to a lightweight composite wall panel and belongs to the field of building materials. Not only is a novel building material developed, but also a new field is opened up for urbansludge treatment. The wall panel is a square thick plate, grooves or ridges are processed at four side faces of the wall panel respectively. The grooves and the ridges are oppositely disposed, that is, a groove is processed at one side face, and the ridge is processed on the other corresponding side face. The wall panel is prepared from, by weight ratio, 65-75% of sludge ceramsite, 12.5-17.5% ofcement and 12.5-17.5% of gypsum. Water accounts for 72-78% the weight of the cement and the gypsum. The weight ratios of the weights of additives to the weight of the cement and the gypsum are high iron powder 0.8-1.2%., cellulose 0.08-0.12%., alkali inhibitor 1.8-2.2%., and water reducing agent 1.8-2.2%.. The lightweight composite wall panel has the advantages of high precision, small size, lightweight, good sound insulation and heat insulation effect, energy saving and environmental protection, simple and convenient construction and high efficiency, and can be widely used in the construction of interior walls and exterior walls of buildings.

Description

technical field [0001] The invention belongs to the field of building materials, and mainly relates to a lightweight composite wallboard for building inner and outer walls of masonry buildings. Background technique [0002] The interior and exterior walls of buildings are mainly made of blocks of various materials or shapes. Traditional blocks need to be bonded with cement mortar when building walls to ensure the firmness of the overall wall. Since the thickness of the cement mortar is difficult to control and the position of the blocks is also difficult to control, the overall flatness of the wall is poor, which brings difficulties to the later construction. The wall needs to be leveled several times to achieve the desired effect. Increased the thickness of body of wall simultaneously, also increased the cost of construction, reduced the efficiency of construction. Part of the blocks are formed by pressing, which cannot satisfy the production of larger blocks due to the l...
