Abstract

The utility model relates to a hollow square brick. The surface of a thickness direction is provided with at least a shallow blind grove or at least a row of shallow blind holes; the other surface of the thickness direction is provided with at least a row of deep blind holes; compared with the existing hollow square brick, the utility model has the advantages of light weight, sound insulation, heat-insulating and high strength, and the wall body paved by the hollow square brick is firm.

Description

A kind of Hollow square bricks

The utility model relates to a kind of construction wall bearing bricks, specifically, relates to a kind of Hollow square bricks.

Utility model patent CN2242167Y discloses a kind of back cover hollow brick.The brick body of this brick has cavity, and the direction of cavity is vertical with brick body length direction, and the end sealing of cavity is provided with reinforcing rib in the cavity.This brick has lightweight advantage.But because of the cavity chamber of this brick is bigger, this has not only reduced the intensity of brick, and has significantly reduced the contact area of brick and brick when building a wall, and makes body of wall become insecure.

The purpose of this utility model provide a kind of in light weight, intensity is high, sound insulation, heat insulation, can improve the Hollow square bricks of the fastness of wall greatly.

The purpose of this utility model is achieved in that at least one shallow blind groove or the shallow blind hole of at least one row is set on first surface on the square brick thickness direction, on second surface of square brick thickness direction the dark blind hole of at least one row is set.

Compare with above-mentioned existing back cover hollow brick, because of Hollow square bricks of the present utility model has a plurality of dark blind holes on a surface of thickness direction, the chamber in each hole is less, but total chamber is bigger, hole wall is arranged between the Kong Yukong, the weight saving that this not only makes brick has good sound insulation, effect of heat insulation, and the intensity of brick is improved greatly; Because of Hollow square bricks of the present utility model has a plurality of shallow blind holes or at least one shallow blind groove on another surface of thickness direction, when building a wall, mortar be layered on this table and on, and enter in shallow blind hole or the shallow blind groove, just combine firmly with Hollow square bricks after the drying, thereby improved the fastness of body of wall greatly.

Fig. 1 is the broken section front view of an embodiment of Hollow square bricks of the present utility model;

Fig. 2 is the vertical view of Hollow square bricks shown in Figure 1;

Fig. 3 is the upward view of Hollow square bricks shown in Figure 1;

Fig. 4 is the broken section front view of another embodiment of Hollow square bricks of the present utility model;

Fig. 5 is the vertical view of Hollow square bricks shown in Figure 4;

Fig. 6 is the upward view of Hollow square bricks shown in Figure 4.

With reference to the accompanying drawings Hollow square bricks of the present utility model is described in detail.In these accompanying drawings, the identical or similar part of Hollow square bricks is represented with identical label.

Shown in Fig. 1～3, the Hollow square bricks of first embodiment of the utility model is represented with label 1 and label 2 respectively on two surfaces of thickness direction.On surface 1, the shallow blind hole of at least one row is arranged, the shallow blind hole 11 of three rows is arranged as shown in Figure 2.The degree of depth of shallow blind hole 11 is about 2mm.The size of shallow blind hole 11 is relevant with row's number.When having only the shallow blind hole of row's (not shown), shallow blind hole 11 can be more greatly; For example during the shallow blind hole 11 of six row's (not shown), shallow blind hole 11 can be littler as many rows.That shallow blind hole 11 can be is cylindrical, conical, truncated cone or water chestnut taper, water chestnut taper type, Figure 1 shows that cylindrical.On surface 2, the dark blind hole of at least one row is arranged, the dark blind hole 21 of three rows is arranged as shown in Figure 3.The degree of depth in dark the region between the heart and the diaphragm hole 21 is about 48mm usually.The size of dark blind hole 21 is relevant with row's number.When having only the dark blind hole 21 of row's (not shown), dark blind hole 21 can be more greatly; For example during the dark blind hole 21 of six row's (not shown), dark blind hole 21 can be littler as many rows.Dark blind hole 21 can have the shape identical with shallow blind hole 11, Figure 1 shows that truncated cone.

The structure of the structure of the Hollow square bricks of second embodiment of the present utility model shown in Fig. 4～6 and the Hollow square bricks of first embodiment of the utility model shown in Fig. 1～3 is basic identical, just on surface 1, replaced the shallow blind hole 11 shown in Fig. 1 and 2, shown in Figure 4 and 5 with shallow blind groove 12.On surface 1, have a shallow blind groove at least, the shallow blind groove 12 of three rows is arranged as shown in Figure 5.The degree of depth of shallow blind groove 12 is about 2mm.The width of shallow blind groove 12 is relevant with row's number.When having only the shallow blind groove 12 of row's (not shown), shallow blind groove 12 can be wideer; For example during the shallow blind groove 12 of six row's (not shown), shallow blind groove 12 can be narrower as many rows.In addition, the dark blind hole 21 on the Hollow square bricks of the present utility model surface 2 has the identical shape of dark blind hole 21 on the Hollow square bricks surface 2 with last embodiment, and dark blind hole 21 shown in Figure 4 is cylindrical.

It is the material employing stamping method manufacturing of major ingredient that Hollow square bricks of the present utility model is suitable for flyash, coal ash slag, steel slag, broken sandstone.

Claims

1. a Hollow square bricks is characterized in that, at least one shallow blind groove or the shallow blind hole of at least one row are arranged on a surface on the square brick thickness direction, and the dark blind hole of at least one row is arranged on another surface of square brick thickness direction.

2. according to the described Hollow square bricks of claim 1, it is characterized in that said dark blind hole is columniform or truncated cone.
