Description

an exterior decorative brick

technical field

The utility model relates to building bricks, in particular to a building exterior decorative brick.

Background technique

Usual building bricks are cuboid or cube red bricks, cement bricks or cinder bricks. These bricks are piled up to form the wall of the building. Bond to build the wall to enhance its integrity. In order to reduce the usage of building bricks, the body of wall can be made of other materials, and only very thin exterior decorative bricks are pasted on the body of wall on the outer wall surface to achieve the effect of brickwork. As an exterior decorative component, the exterior decorative brick has withstood the test of wind and rain, so the adhesiveness of its back side has become a problem that cannot be ignored in building safety. The back side of the existing exterior decorative bricks is often only roughened or treated with horizontal straight grooves. For exterior decorative bricks, the bonding performance of such a design cannot meet the ideal requirements of various building exterior decorative bricks.

Utility model content

The technical problem to be solved by the utility model is to provide an exterior decorative brick with good cohesiveness and high safety by overcoming the disadvantages of unsatisfactory bonding performance of the exterior decorative brick with roughened surface or horizontal straight groove treatment in the prior art.

The technical scheme adopted by the utility model to solve the technical problem is: to construct a kind of exterior decorative brick, and the said exterior decorative brick is provided with at least one dovetail groove on the contact surface between the brick body and cement or similar materials, so that it is compatible with cement or Similar materials yield good bonding properties.

According to the exterior decorative brick provided by the utility model, it is characterized in that the dovetail groove provided can be in any shape such as horizontal, vertical, oblique and other which can increase the bonding performance.

Implementing the exterior decorative brick provided by the utility model, due to the dovetail groove structure is provided on its contact surface with cement or similar materials, when the brick body is bonded with cement or similar materials, sticky soil or cement mortar will stick to it. When the adhesive is filled into the dovetail groove of the brick body, when the adhesive is solidified, the adhesive is bonded to the cylindrical surface of the dovetail groove and the plane where the dovetail groove is located, so that the brick body cannot be moved, thereby strengthening the brick body and the adhesive. The cohesiveness of the knot. At the same time, due to the existence of dovetail grooves on the contact surface between the brick body and the cement, the cohesion between the brick body and the cement is increased, and the gap between the brick body and the brick body can also be greatly reduced, so that the exterior decorative brick and cement Or similar materials produce good bonding performance, thereby greatly improving its safety performance.

Description of drawings

The utility model will be further described below in conjunction with accompanying drawing and embodiment, in the accompanying drawing:

Fig. 1 is a perspective view of the first embodiment of the utility model exterior decorative brick;

Fig. 2 is a cross-sectional view of the utility model when the exterior decorative brick is bonded with the adhesive;

Fig. 3 is a perspective view of the second embodiment of the exterior decorative brick of the present invention.

Detailed ways

As shown in Figures 1 and 2, in the first embodiment of the present utility model, the provided exterior decorative brick is provided with a dovetail groove 102 longitudinally on the contact surface 101 between the brick body 100 and cement or similar materials. The number of dovetail grooves is at least one, and the dovetail groove runs through the brick body, and the groove depth does not exceed half the height of the brick body. Adhesives of similar materials make it bonded to the wall; different from ordinary brushed surfaces or bricks for exterior decoration with horizontal and straight grooves, the exterior decorative bricks provided by the utility model are bonded to the wall It is tighter, and there is no need to fill more adhesives between the bricks, which saves materials and makes the outer wall more beautiful, and also improves the safety performance.

As shown in Figure 3, in the second embodiment of the utility model, the provided exterior decorative brick is provided with a dovetail groove 103 laterally on the contact surface 101 between the brick body 100 and cement or similar materials, and the number of dovetail grooves At least one dovetail groove runs through the brick body, and the groove depth does not exceed half the height of the brick body.

In the third embodiment of the present utility model, the exterior decorative brick is obliquely provided with dovetail grooves on the contact surface between the brick body and cement or similar materials, and the number of dovetail grooves is at least one, and the dovetail grooves run through it For the brick body, the depth of the groove shall not exceed half of the height of the brick body.

In the fourth embodiment of the present utility model, the exterior decorative brick is provided with dovetail grooves longitudinally and transversely on the contact surface between the brick body and cement or similar materials, and the number of dovetail grooves in each direction is at least one , the dovetail groove runs through the brick body, and the groove depth does not exceed half the height of the brick body.

Based on the above-mentioned embodiments, what the utility model protects is not limited to the above-mentioned embodiments, and improvements in other directions and quantities on the same surface should also fall within the scope of protection of the utility model.

Claims (5)

1. An exterior decorative brick, consisting of a rectangular or square brick body, characterized in that at least one dovetail groove is provided on the contact surface between the brick body and cement or similar materials. 2. The exterior decorative brick according to claim 1, wherein the dovetail grooves are arranged transversely. 3. The exterior decorative brick according to claim 1, wherein the dovetail grooves are arranged longitudinally. 4. The exterior decorative brick according to claim 1, wherein the dovetail groove is arranged obliquely. 5. The exterior decorative brick according to any one of claims 1-4, wherein the dovetail groove runs through the brick body, and the groove depth does not exceed half the height of the brick body.
