Briefly describe the construction process of brick masonry

The general order of brick wall masonry is to copy the flat, pay off, place the bricks, stand the number of leather rods, plate corners, hang the line, masonry, hook joints, and clean.

Brick wall: The wall made of bricks and concrete masonry has good load-bearing, heat preservation, heat insulation, sound insulation, fire prevention, durability and other properties, and is widely used in low-rise and multi-storey houses. Brick walls can be used as load-bearing walls, perimeter retaining walls and internal dividing walls.

Masonry method: refers to the arrangement of bricks in masonry. In order to make the masonry solid and stable and form a whole, the vertical masonry joints between the upper and lower skin bricks must be regularly staggered, called staggered joints.

The staggered joints can also make the façade of the clear water wall form a regular pattern. The basic assembly method of the solid wall is the upper and lower skins, one shun and one ding, etc.

The thickness of a brick wall generally depends on the requirements for the strength and stability of the wall. The thickness of the exterior wall of a building with heating requirements needs to be considered for thermal insulation. However, when masonry, it must also be determined in combination with the specifications of the bricks.

Taking standard bricks as an example, the thickness of the wall can be built into various thicknesses such as half bricks (12 walls, 4 bricks (18 walls), one brick (24 walls), one and a half bricks (37 walls), two bricks (49 walls), two bricks and a half (62 walls) and so on.

Process flow: The masonry method of brick wall refers to the arrangement and combination method of bricks in masonry. It should meet the basic requirements of horizontal and vertical, full mortar, staggered joints, and avoiding through joints to ensure the strength and stability of the wall.

One Shun and One Ding.

This masonry method is a layer of bricks and a layer of bricks, which are arranged alternately and repeatedly combined. In the corner part to add 3 4 bricks (commonly known as seven points) for the transition. This masonry method is characterized by good lap joint, no through joint, and strong integrity, so it is widely used.

All cis. This masonry method is built along the bricks of each skin. The upper and lower skin overlap left and right for half brick, it is only suitable for half brick walls.

Straight and alternate.

This masonry method is made of alternating bricks and bricks. The wall thickness of this masonry method is at least one brick wall, it has good integrity, and the wall surface is beautiful.

Multi-shun one-ding.

This kind of masonry method is usually divided into three and one ding and five shun and one ding, and its practice is to add one skin of bricks and bricks every three or five skins to bricks and build a skin of bricks on top of each other. The problem with the multi-shun one-ding masonry method is that there are through-seams.

The construction technology and construction points of brick wall masonry are as follows: 62616964757a686964616fe78988e69d8331333361326336

Brick masonry, a monolithic material made of bricks and mortar, is one of the most widely used building materials. According to whether steel bars are configured in the masonry, it is divided into unreinforced brick masonry and reinforced brick masonry.

Brick wall masonry construction technology:

1. Copy flat and elastic line.

Before building the wall, the top surface or floor of the foundation should be leveled with cement mortar or fine stone concrete, and then the axis of the wall, the edge line and the position of the door and window openings should be popped up according to the axis control points that are drawn out.

2. Arrange bricks.

When masonry, the bricks should be placed first to discharge the width of the ash joint. When placing bricks, attention should be paid to the influence of the position of doors and windows, brick stacks, etc. on the ash joints, and at the same time, it is necessary to consider the assembly method of the wall between the windows, as well as where the seven-point bricks and half bricks are built, so that the vertical joints of each skin brick are staggered with each other. The assembly method of each part of the same wall should be unified, and the top and bottom should be consistent.

3. Stand up and count the rods.

The thickness of the bricks, the thickness of the ash joints, the positions of the doors and windows, floors, lintels, ring beams, roof trusses and other components are drawn on the number of poles. Leather poles are erected at the corners of the wall and some junctions, and the spacing should not exceed 15m. When standing the piping number rod, the level should be used to copy the level, so that the floor elevation line on the piping rod is located in the design elevation position.

4. Disc angle and hanging line.

The corner of the wall is the main basis for determining the wall surface, so the corner of the wall can be built first according to the number of rods, and then the middle wall can be built according to the alignment line.

5. Masonry and joints.

When laying bricks, you must first pull the alignment. Walls with a thickness of more than one and a half bricks should be pulled on both sides, and the bricks should be built according to the alignment. The "three-one" bricklaying method should be used to build ordinary brick walls, that is, the operation method of "a shovel of ash, a brick, and a kneading and pressing".

The vertical joints should be squeezed or slurred to make the mortar full, and it is strictly forbidden to flush the joints with water lead. It can also be built by grouting method, and the length of grouting shall not exceed 750mm; When the temperature exceeds during construction, the length of the slurry shall not exceed 500mm.

Key points of brick wall masonry construction:

1. The bricks used for the surface of the clear water wall should have neat corners and uniform color.

2. When building a brick wall, the bricks should be watered and moistened 1 2 days in advance, and the moisture content should be 10 15.

The bricks on each layer of the wall of the mm thick load-bearing wall should be made of whole bricks. Under the beam or beam pad and the eaves, waist line, etc., the whole brick should also be built.

4. Transparent seams, blind seams and false seams shall not appear in the vertical ash seams.

5. When the brick wall is repaired at the temporary break, the surface of the joint must be cleaned, watered and moistened, and filled with mortar to keep the ash joint straight.

6. The corners and junctions of the brick wall should be masonry at the same time, and the mausoleum hall is strictly forbidden to separate the internal and external walls without reliable measures. For the temporary fault that can not be masonry at the same time and must be left in place, Huaichun should be built into a diagonal chariot, and the horizontal projection length of the diagonal chariot should not be less than 5 3 of the height.

Acceptance criteria: 1. The allowable deviation of the top surface elevation of brick masonry is 15mm;

2. The allowable deviation of the surface flatness of the brick masonry is 5mm;

3. The allowable deviation of the height and width of the openings of brick masonry doors and windows is 5mm;

4. The allowable deviation of the upper and lower window openings on the outer wall of the brick masonry is 20mm;

5. The allowable deviation of the straightness of the horizontal ash joint of the brick masonry is 10mm;

The general order of brick wall masonry is to copy the flat, pay off, place the bricks, stand the number of leather rods, plate corners, hang the line, masonry, hook joints, and clean.

Key points of brick foundation construction:

1. The moisture-proof layer of the foundation is cement waterproof mortar;

2. The brick foundation is generally built in the form of masonry;

3. In order to ensure that the foundation can be on the same horizontal plane after being laid, the foundation skin number rod must be set in advance at the corner of the cushion and the high and low steps;

4. When laying bricks, the bricks at the corners and junctions of several skins should be built according to the number of skins, and the alignment should be pulled in between, and then the middle part should be built; The upper part of the pipeline passing through the foundation should be reserved for settlement clearance;

5. After the foundation is laid, the backfill on both sides should be carried out at the same time, and the layers should be tamped to prevent the asymmetrical backfill from causing the foundation to move sideways and cause quality accidents.

The general order of brick wall masonry is to copy the flat, pay off, place the bricks, stand the number of leather rods, plate corners, hang the line, masonry, hook joints, and clean.

General BAI order:

1. Copy the level. 2. Pay-off.

3. Placing bricks. 4. Lidu

The number of leather rods

5. a disc angle. 6. Hang the line.

7. Masonry. 8. Hook seams.

dao9, clean up special.

Buy cement, sand, bricks, and vertical rulers, and follow the 1 to 3 ratio, get the mortar, and build it directly.

The masonry construction process is preparation for the operation, brick watering, mortar mixing, brick walling, acceptance.

1. For leveling treatment, you can use cement mortar to level the wall more smoothly, when leveling, pay attention to not have any stains, if there are stains, clean up in time.

For pay-off, the masonry form of one shun and one ding is adopted on the brick foundation, and the pay-off must be kept flat, otherwise the masonry is prone to tilt (as shown in the figure below).

2. In order to ensure that the foundation bricks can be on the same level after the foundation bricks, the foundation skin number rod must be set in advance at the corner of the cushion, so as to ensure that the foundation bricks maintain the same level (as shown in the figure below).

3. When laying bricks, you can use the leather number rod to pull the alignment line with the bricks at the junction, and then build the middle part after the thickness, and then pass through the upper part of the foundation pipeline to reserve the settlement gap (as shown in the figure below).

4. After the completion of the brick masonry, the backfill treatment should be carried out at the same time at the position on both sides, and the ramming should be layered to avoid the phenomenon of asymmetric backfilling, causing foundation deviation, quality and other problems (as shown in the figure below).

5. After the brick masonry construction is completed, the joints should be hooked, and the places with gaps should be filled, and the gaps should be filled. <

Construction technology of brick wall masonry:

1. Copying: make the bottom elevation of each section of the wall on the same horizontal plane;

2. Swing foot: on the base surface of the pay-off, it is used for dry brick test pendulum according to the selected assembly method;

3. Vertical leather floor rod: make the thickness of the horizontal seam uniform;

4. Disc angle: three skins and one hanging, five skins and one leaning to ensure the quality of the disc angle;

Key points of construction of brick wall masonry:

1. The joints are firm, cleaned, watered and moistened, filled with mortar, and kept the ash joints straight;

2. It is strictly forbidden to flush the joints with water;

3. The corners and junctions of the brick masonry should be left oblique and straight, and the seismic fortification area should not be left straight;

4. In the case of non-seismic fortification and seismic fortification intensity of 6 degrees and 7 degrees, when the diagonal chariot cannot be left, the straight chariot can be left, but the straight chachariot must be made into a convex chariot;

5. The height difference of the adjacent working section of the masonry shall not exceed the height of the sail stove of a building scattered layer, and shall not be greater than 4 meters.
