Abstract

A method for manufacturing a wall brick without pointing, which is to set a fixed brick joint on the brick edge in advance when manufacturing a wall brick adobe. The brick joints are obliquely raised from the back of the brick body (from back to front), cement mortar layers of the connecting surfaces of the two bricks are reserved during masonry, the contact surfaces of the upper brick body and the lower brick body are not changed on the plane of the brick joints, and the improved pointing-free wall brick does not influence the connecting strength of a wall body. The brick joints are concaved inwards from the brick faces to form neat and smooth semicircle shapes. The brick joints are respectively arranged on the front surface or the side surface of the brick body according to the characteristics that the front surface and the side surface are needed to be staggered (joint pressing) when the wall bricks are built: parallel brick joints, (parallel) left lower corners, (parallel) right lower corners), six (kinds of) samples: and firing and forming the green bricks of the front three (kind) sample and side three (kind) sample types. When the brick is used for building the wall without pointing, the working procedure of pointing can be omitted by only filling cement mortar on the brick surface.

Description

Manufacturing method of pointing-free wall brick

Technical Field

The invention belongs to the field of building materials.

Background

After the existing wall bricks are built, mortar in brick joints is loosely exposed outside, and then the mortar is specially subjected to pointing treatment, namely, cement mortar in connecting joints is compacted and troweled by a tool from outside to inside. The brick joint can be firmer and more beautiful through the working procedure.

Disclosure of Invention

The invention provides a method for manufacturing a pointing-free wall brick, which is to pre-arrange fixed brick joints on the edges of a brick body when manufacturing a wall brick blank. The brick joints are obliquely raised from the back of the brick body (from back to front), cement mortar layers of the connecting surfaces of the two bricks are reserved during masonry, the contact surfaces of the upper brick body and the lower brick body are not changed on the plane of the brick joints, and the improved pointing-free wall brick does not influence the connecting strength of a wall body. The brick joints are concaved inwards from the brick faces to form neat and smooth semicircle shapes. The brick joints are respectively arranged on the front surface or the side surface of the brick body according to the characteristics that the front surface and the side surface are needed to be staggered (joint pressing) when the wall bricks are built: parallel brick joints, (parallel) left lower corners, (parallel) right lower corners), six (kinds of) samples: and firing and forming the green bricks of the front three (kind) sample and side three (kind) sample types. When the brick is used for building the wall without pointing, the working procedure of pointing can be omitted by only filling cement mortar on the brick surface.

Drawings

FIG. 1 (three) is a schematic view of a brick joint. FIG. 2 (brick joint) is a schematic side view. In the figure: 1 brick body, 2 brick joints, 3 cement mortar layers, A parallel (brick joints), B left lower turning (brick joints), C right lower turning (brick joints), D transverse side (brick joints), E positive side (brick joints).

Detailed Description

The pointing-free wall brick is characterized in that (1) a brick joint is preset on a brick body when a wall brick blank is manufactured, (2) the brick joint is obliquely raised from the rear (from back to front) of the brick body, and (3) a cement mortar layer of a connecting surface of two bricks is reserved when the brick is built, wherein the contact surface of an upper brick body and a lower brick body is not changed in the plane of the brick joint. The improved pointing-free wall brick does not influence the connection strength of the wall body. (2) The brick joint is concave inwards from the brick body (1) to form a neat and smooth semicircle. According to the requirements of (1) brick masonry standards, preset brick joint specifications are respectively: and (3) sintering and forming the green bricks of the six (kind) samples (three (kind) samples on the front and side surfaces respectively) (2) brick joint types, wherein the three (A) bricks are parallel to each other, (B) bricks are parallel to the left lower corner (brick joint), and (C) bricks are parallel to the right lower corner (brick joint).

Claims (2)

1. The method for manufacturing the pointing-free wall brick is to add a preset (2) brick joint in advance on a brick body when manufacturing a wall brick blank, and is characterized in that: (2) The brick joints are obliquely raised (from inside to outside), a cement mortar layer (3) is reserved on the connecting surface of the two bricks during masonry, and the brick joints (2) are concaved inwards from the brick body (1) to form a neat and smooth semicircle.

2. The brick joint of claim 1 (2), wherein: the brick joints (2) are three types: parallel brick joints, (B) (parallel) left lower corner, (C) (parallel) right lower corner, six (kinds of) samples: three samples were added on the front side and three samples on the side.
