Description

A dry code splicing hollow brick

technical field

The utility model belongs to the field of building engineering wall materials, in particular to a dry-code spliced hollow brick.

Background technique

The filled walls in house construction are mostly built with hollow bricks. Hollow bricks have the advantages of lightness and material saving, and when hollow bricks are produced, some insulating materials can be filled in their hollow bodies to make self-insulating bricks. Therefore, in construction fields are widely used.

When the hollow bricks are built on site, cement mortar must be used for masonry. Cement mortar is used as a bonding material, so that the hollow bricks are bonded together to form a wall with a certain strength. This technology has played a huge role in the development of building wall technology and made great contributions to the urban construction of our country. At present, the state advocates the development of material-saving, energy-saving and environmentally friendly construction technologies in the construction industry, and promotes prefabricated buildings to reduce construction waste pollution and construction dust pollution. Obviously, the traditional brick wall construction technology has obvious disadvantages: 1. This process not only requires a large amount of cement mortar materials, but also causes pollution on site and produces some mortar waste and garbage; 2. The entire masonry process has more mortar waste The link of mixing and mortar filling will inevitably reduce the speed of masonry; 3. After the mortar is applied, the gap width between the upper and lower bricks will be increased. construction efficiency. Therefore, it is necessary to develop material-saving, energy-saving, efficient and environmentally friendly wall masonry materials and technologies.

detailed description

The following is a specific embodiment of the present utility model, which will be further described in conjunction with the accompanying drawings.

As shown in Figure 1, a dry-code spliced hollow brick includes a brick body 1, a mortise 6 is provided in the middle of the bottom of the brick body 1, and a mortise that can form a mortise and tenon structure with the tenon 6 is provided on the top of the brick body 1. 2. The two sides of the top mortise 2 of the brick body 1 are provided with a number of reinforcement grooves 3; the inside of the brick body 1 is provided with a plurality of holes, and the outermost two holes are the insulation layer 4 filled with insulation materials; The top and bottom surfaces of the brick body 1 are provided with vertical through-cavity injection cores.

In this embodiment, the thermal insulation layer 4 is filled with polystyrene foam thermal insulation material, and the brick body 1 is provided with three holes, with a hollow layer 5 in the middle. After the tenon 6 and the mortise 2 are engaged, a closed reinforcement groove 3 is formed. The mortise 6 and the mortise 2 can just be embedded in each other structurally, and are tightly matched, so as to ensure that the upper and lower adjacent blocks are interlocked with each other and the blocks are not staggered.

As shown in Figure 2, the number of the cores is three, including a center core 7-1 in the middle and two end cores 7-2 at both ends. The cross-section of the center core 7-1 It is an ellipse whose long axis is along the length direction of the brick body, and the section of the end injection core 7-2 is a semi-ellipse whose long axis is along the length direction of the brick body with the opening facing outward.

As shown in Figure 3, when the bricks are stacked on site, the lower layer of bricks should be stacked first with the mortise 2 upwards, and then the second layer of bricks should be stacked. The mortise 6 of the upper brick corresponds to the mortise 2 of the lower brick, and the fit is tight to ensure that the upper and lower bricks are flat and closely matched without cement mortar masonry. A reinforcing bar groove 3 is arranged on the top of the brick, and several horizontal tie bars are arranged in the reinforcing bar groove 3 every few skins of bricks to strengthen the connection between the wall and the columns at both ends. The brick has a vertical core injection design, which can ensure that the vertical core injection of the wall is penetrated from top to bottom, no matter whether the brick body is aligned up and down or half-brick masonry, which is convenient for the layout after the wall is built. Vertically reinforced steel bars or poured mortar form hidden columns to improve the overall strength and stability of the wall.
