Description

Concrete grid framework wall

The invention relates to a manufacturing technology of a building wall, which has the characteristics of one-step forming, simple manufacturing process, good strength of the manufactured wall, light weight and low manufacturing cost.

The wall is the basic component of the house. The traditional wall is made by arranging and stacking clay bricks one by one and adding lime or cement mortar between bricks to bond them into a whole. And then the rough surface is sluiced and ash scraped to make the rough surface smooth and white. The traditional method has the disadvantages of complex process, high cost and heavy structure, and the generated waste material causes pollution to the environment.

The invention provides a technology for manufacturing a wall body molded by casting on site, wherein a wall body forming unit consists of two identical refined rectangular face bricks and a non-bearing sandwich brick arranged in the middle. One side of the face brick is smooth, the other side of the face brick is rough, and the plane shapes of the sandwich brick and the face brick are basically similar to a rectangle. The former has smaller area than the latter, and a through hole is formed between two planes attached to the facing bricks, and the hole is connected with the upper and lower horizontal planes through a groove. During construction, the two face bricks are aligned with the geometric center of the sandwich brick, and the three face bricks are tightly combined to form a composite light hollow block with a groove at the periphery and a pouring channel system similar to a metal casting in the inner part. After the building blocks are positioned, concrete mortar is poured into the grooves in the upper parts, the grooves are filled with the mortar, and the mortar flows into the pouring channels, the holes and all gaps between the face bricks and the sandwich bricks. After the concrete mortar is condensed, the face bricks on the two sides are connected into a whole, and the concrete in the pouring gate is equivalent to a ribbed plate of the face brick, so that the effect of increasing the strength of the face brick is achieved. And the concrete mortar poured in the left, right, upper and lower building blocks are connected with each other to form a net-shaped framework of the whole wall body. On two side faces of the wall, all face bricks are connected into one piece to form a large smooth and bright wall surface. The formed net-shaped framework becomes a main stressed member of the wall body. The face brick is not only a moulding and pouring template, but also a permanent decoration panel for forming a wall body. Simultaneously, the concrete framework bears the load and is stressed together with the concrete framework. The sandwich brick is made of light materials, such as plastic foam, sawdust produced by grinding waste wood and the like, does not play a role in bearing, only plays a role in connecting the face brick and a die cavity in the forming process, and plays a role in heat insulation and sound insulation after being built. The thickness of the wall body and the thickness of the concrete size are determined according to the shape and the size of the sandwich brick. Because sandwich brick weight is very light, and the whole weight of building block is lighter before the pouring, convenient the removal, so the plane size of rectangle face brick and sandwich brick can be made great to improve efficiency of construction and pleasing to the eye visual effect. In order to ensure the wall thickness precision and the surface smoothness, certain requirements are required on the thickness dimensional tolerance of the sandwich brick and the face brick. In order to facilitate positioning during assembly and ensure the integrity of the concrete framework and the face brick, a plurality of bosses can be manufactured on two side surfaces of the sandwich brick, and shallow pits are manufactured at the positions of the rough surface of the face brick, which are opposite to the rough surface of the face brick, wherein the bosses are higher and the pits are shallower. After the assembly, a gap exists between the combined planes of the face brick and the sandwich brick. After pouring, the gaps are filled with concrete mortar, and the sandwich bricks are integrally wrapped except the boss parts, so that the combination of the face bricks and the sandwich bricks is enhanced, and the strength of the face bricks is also increased. The assembly of the face brick and the sandwich brick is carried out on a construction site, the positioning implementation can also be carried out on a wall body in the construction process, the combination and the building are simultaneously completed, the face brick and the sandwich brick can be poured immediately after being positioned, and the face brick and the sandwich brick can also be poured in layers after being built in a row. In the pouring process, iron wires can be properly placed in the grooves to serve as reinforcing steel bars, so that the strength of the wall body is improved. The face brick can be ceramic tile, stone plate brick, wood brick or clay brick processed by polishing and plastic spraying. If a large face brick is adopted, a plurality of sandwich bricks can be combined with the face brick. Before assembly, the facing bricks on two sides can be drilled, and connected by a plurality of small-diameter bolts, after the pouring is finished and the bricks are solidified, the bolts are removed, and the small holes are slightly repaired. The formed wall surface does not need to be plastered or scraped with ash. Essentially no waste material is produced. Meanwhile, water and electricity pipelines can be directly placed in brick joints during masonry, and the brick joints are convenient and attractive.

The invention is further illustrated by the following figures and examples.

Fig. 1 is a three-dimensional view of a block constituting a wall body, which is composed of two decorative face bricks (1) and a sandwich brick (2). During construction, a face brick is firstly erected on the side of a building position, then the corresponding positions of the sandwich brick and the face brick are coated with an adhesive, the sandwich brick is placed on the inner side of the face brick, the centers of the sandwich brick and the face brick are aligned, and then the other face brick is placed. Because the side area of the sandwich brick is smaller than that of the face brick, concave grooves are formed on the periphery of the combined building block.

Figure 2 is a three-dimensional view and a partial cross-sectional view of a sandwich tile molding. The sandwich brick can be made of foam plastics, two side faces of the sandwich brick are basically similar to the rectangle of the face brick, and the sandwich brick has a smaller area than the face brick, so that grooves are formed on the periphery after the sandwich brick is adhered to the face brick. The planes on the two sides of the concrete pouring device are provided with 5 circular bosses and two penetrating circular holes (3), so that the facing bricks on the two sides can be connected after the concrete pouring. Four grooves (4) are respectively arranged in four directions of the two round holes and are communicated with the upper plane and the lower plane. The boss is used for positioning, on the one hand, after the boss is combined with the face brick, a gap is formed between the plane of the sandwich brick around the boss and the face brick, and cement mortar in the gap after pouring is equal to the thickness of the face brick, namely the strength of the face brick and the wall is increased.

Figure 3 is a front view and a partial section of a rough face of a tile, in which corresponding 5 recesses (5) are made for easy positioning during gluing. The depth of the concave pit is less than the height of the boss of the sandwich brick.

Fig. 4 is a partial cross-sectional view of the completed wall. The combined building blocks of the face bricks (1) and the sandwich bricks (2) are arranged and stacked on a floor or a floor slab (7), concrete mortar is poured into the groove after each building block is positioned, and the concrete poured into all the building blocks are connected with each other to form a piece of grid (6). Meanwhile, the decorative face bricks on both sides are connected to form a beautiful and firm wall body.
