Description
Technical Field
The invention relates to the technical field of decoration engineering of buildings, in particular to a brick-concrete composite wall and a construction method thereof.
Background
The facing brick including glazed brick, ceramic tile and water brick is smooth, clean, dirt resistant, wash resistant and long in service life, and may be used as replaceable wall decorating material in many places. In the case of a wall covering such as a kitchen or toilet which requires frequent contact with water and frequent washing, only a surface tile is sufficient. Historically, it has also been demonstrated that tile walls can last hundreds of thousands of years and still maintain excellent decorative effects, such as mosaic wall tiles of various ancient churches, which are still lifelike over thousands of years.
The installation and use of tiles has not changed greatly in the last millennium, and the tiles are still adhered to a mounting substrate by mortar. The tile-bonding mortar generally comprises two types of components, one being an organic component represented by starch or gelatin, and the other being an inorganic component represented by lime or cement. The organic component has a certain bonding ability at the beginning but poor weatherability, while the inorganic component has good weatherability but takes a long time to develop bonding strength, and the two combine to complete the bonding of the tile.
When the face bricks are adhered, mortar can be laid on a very thin layer, so that mortar fullness is very low, in practical use, after one face brick is detached, the mortar below the face brick is adhered to less than half of the area, and the larger the area of the face brick is, the poorer the mortar fullness is. The method leads the adhesion of the face bricks to be not reliable enough, no decoration master dares to paste large-area face bricks under the ceiling, only the mosaics with corresponding requirements can be selected and used, the mosaics have a plurality of splicing seams due to small area, and are easy to dirty, and the decoration effect is not as good as that of the large-area face bricks. In addition, because the bonding is not reliable enough, the use of face bricks on more than eight floors of building outer walls is strictly forbidden by the country.
In addition to using mortar to attach tiles to a mounting substrate, tiles also have a form of mounting, namely composite walls. The face bricks adopted by the composite wall are usually plain bricks, and an additional wall body is built outside the installation base. The installation base can be a masonry wall or a concrete wall, and after the roughening, mortar is brushed and then laid along the installation base to build the ganged bricks. The connection of the tile layer to the installation base in the composite wall is more secure than the use of mortar-pasted tiles, which is generally used for reconstruction of old houses or antique buildings, but is limited by the construction method, and the composite wall cannot be used for the ceiling of a building or the outer wall of a building with more than two layers.

Detailed Description
As shown in fig. 7, a brick-concrete composite wall for a building side wall or a building ceiling comprises a cast-in-place concrete layer 2 and a face brick layer 3 adhered to one or both surfaces of the cast-in-place concrete layer 2, wherein each face brick constituting the face brick layer 3 is connected with a wall reinforcement cage 21 in the cast-in-place concrete layer 2; when an earthquake occurs, the concrete part of the cast-in-place concrete layer 2 can be damaged, but the wall reinforcement cage 21 can be kept complete, and at the moment, if the face bricks are connected to the wall reinforcement cage 21, the face bricks can not easily fall off in the earthquake. In actual use, ceilings such as building ceilings can adopt a wall body with one face brick layer 3, the face brick layer 3 is arranged below the ceiling, and pseudo-classic buildings or building side walls can adopt a wall body with two face brick layers 3.
The back of the face brick is provided with a dentate protuberance 31 which is inserted into the cast-in-situ concrete layer 2 and used for strengthening the bonding strength between the face brick and the concrete. The tooth-shaped protrusions 31 have the second function, one function is to hang the face brick like mortise and tenon joints, so that the face brick is not easy to fall off, the other function is to resist the shearing force parallel to the face brick, the tooth-shaped protrusions 31 in the embodiment are rectangular, the structure is convenient to process, if the connection strength is pursued, the tooth-shaped protrusions 31 can be made into a shape that the cross section is gradually increased from the inside to the outside of the face brick, namely, a shape of a dovetail joint, so that the connection strength is higher, but the face brick is not easy to process.
In the face brick layer 3, adjacent face bricks are connected with each other through double-sided adhesive tapes, wherein the double-sided adhesive tapes are only used for temporary fixing; the opening of the brick joint on the outer surface of the face brick layer 3 is plugged with structural adhesive for water resistance. The connecting wire 5 has the second function, on one hand, the face brick is prevented from being inclined by the concrete, and on the other hand, the cast-in-place concrete layer 2 is prevented from being damaged and the rear face brick is prevented from falling.
The face brick is bound and connected with a wall body reinforcement cage 21 through a connecting wire 5, and the connecting wire 5 is a metal wire resistant to cement corrosion. The connecting wire 5 can be copper wire, nickel-chromium wire or binding wire, but can not be aluminum wire, and the aluminum wire can be corroded by cement.
The face brick is provided with a thread hole 32 with the length direction parallel to the bottom surface of the face brick, and the connecting thread 5 is arranged in the thread hole 32 in a penetrating way. The reason why the threading holes 32 are required to be parallel to the bottom surface of the tile in the longitudinal direction is to allow the tile to be stably held by the connecting wires 5, and if not parallel, the pulling force is not uniform.
