Description

A hollow plaster wall

technical field

The utility model relates to the technical field of production and manufacture of building materials, in particular to a hollow gypsum wall.

Background technique

The gypsum wall is a light-weight building gypsum product made of building gypsum as the main raw material, which is stirred with water, poured and dried. Because of its characteristics of sound insulation and fire prevention, convenient construction, low-carbon environmental protection, and low price, as a new type of wall material, its market prospect is broad. Gypsum walls are relatively bulky, so they are efficient when used as interior wall filling; they are light in weight compared to cement and brick walls.

However, the gypsum wall also has the defects of insufficient strength and toughness, and the wall is easy to crack, so that the seismic resistance of the wall built by it cannot meet the predetermined technical requirements.

Utility model content

The purpose of the utility model is to provide a hollow gypsum wall, which can enhance the strength and toughness of the hollow gypsum wall, and has the characteristics of easy installation.

A hollow gypsum wall, the key of which is: comprising a wall in a rectangular parallelepiped structure, one end of the wall is provided with a trapezoidal positioning boss, and the other end opposite to the positioning boss is provided with a trapezoidal positioning groove , two rows of through holes are arranged in the wall, the two rows of through holes are arranged in a staggered manner, a reinforcing net is arranged between the two rows of through holes, and flexible fiber nets are arranged on both sides of the two rows of through holes.

The hollow gypsum wall comprises a cuboid-shaped wall, the front and back of the cuboid-shaped wall are wall surfaces, the narrow end faces around the upper, lower, left and right sides are side faces, and one end face of the wall body is provided with a trapezoidal positioning boss, A trapezoidal positioning groove is set on the other end face opposite to this side end face, and the positioning boss is the same size as the positioning groove. Insert the positioning boss of one hollow gypsum wall into the positioning groove of another hollow gypsum wall, and multiple hollow gypsum walls can be realized. Connection of plaster walls.

The trapezoidal positioning boss and the positioning groove are used to connect the wall, which has a simple structure and high positioning accuracy.

There are two rows of through holes in the wall, and one row of through holes is staggered from the other row of through holes by half the hole spacing, so that the two rows of through holes are staggered, and the three adjacent through holes are arranged in the shape of "pin". Increased wall strength.

The staggered arrangement of through holes also prolongs the path of heat transfer or sound transfer, which can further improve the thermal insulation performance and sound insulation effect of the wall.

Reinforcing mesh is used to strengthen the strength of the wall.

Arranging flexible fiber nets near the surface of the wall on both sides of the two rows of through holes can increase the toughness of the wall.

The reinforcing net is a reinforced net.

Casting reinforcement mesh in the wall between two rows of through holes can enhance the strength of the wall.

The flexible fiber net is a high-strength polyester fiber net.

The high-strength polyester fiber mesh has high strength and has holes, which is easy to be integrated with gypsum casting.

Both sides of the positioning boss and the positioning groove are provided with slurry holding grooves.

The said slurry tank is in the shape of a semi-circle arc. When two hollow gypsum walls are put together, the two slurry tanks form a complete circle; gypsum slurry is often applied between the two spliced hollow gypsum walls. Setting the slurry tank can improve the connection strength between two hollow gypsum walls, and can reduce the cracks generated after the gypsum slurry solidifies and dries.

The front and rear walls of the wall are all provided with waterproof coatings.

Existing gypsum walls only have fireproof performance, and their strength decreases under humid climate conditions, and they are easily scratched and turned into powder, which affects the environment.

The length of the wall is 2.5-3.2 meters, the width is 0.6 meters, and the thickness is 0.09-0.18 meters.

The wall body is a cuboid suitable for lying down transportation, and its size is set to be 2.5-3.2 meters long, 0.6 meters wide, and 0.09-0.18 meters thick. When installed vertically, it can be adapted to the internal net height of the existing house , reduce the joints between the hollow gypsum walls, the setting of the wall thickness can increase the usable area of the house and improve the utilization rate.

Beneficial effects: the utility model provides a hollow gypsum wall, which can enhance the strength and toughness of the hollow gypsum wall, and has the characteristics of easy installation.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Fig. 1 and Fig. 2, Fig. 3, the utility model provides a kind of hollow gypsum wall, comprises the wall body 1 that is cuboid shape, and the front and back of cuboid body body of wall 1 is wall surface, and up, down, left, The narrow end faces around the right side are side faces, a longer end face of the body of wall 1 is provided with a trapezoidal positioning boss 2, and the other longer end face opposite to the positioning boss 2 is provided with a trapezoidal positioning groove 3, and the positioning protrusion The size of the platform 2 is the same as that of the positioning groove 3. Two rows of through holes 4 are arranged in the wall 1 along the length direction. The through holes 4 in the two rows are arranged in a staggered manner. Hole spacing, the adjacent three holes are arranged in the shape of "pin", a reinforcing net 5 is arranged between the two rows of through holes 4, and a flexible fiber mesh 6 is arranged near the wall on both sides of the two rows of through holes 4.

The flexible fiber net 6 is a high-strength polyester fiber net.

The reinforcing mesh 5 is a steel mesh.

Both the polyester fiber mesh and the steel mesh are poured directly into the hollow gypsum wall, which can significantly improve the strength and toughness of the hollow gypsum wall.

As shown in FIG. 2 , slurry holding grooves 8 are provided on both sides of the positioning boss 2 and the positioning groove 3 .

The gap between the two hollow gypsum walls needs to be coated with gypsum slurry, and the fast connection is realized after drying. The gypsum slurry placed in the slurry tank 8 can increase the connection strength and reduce cracking between the two hollow gypsum walls.
