Regarding the problem of building masonry wall, about wall problem in masonry structure design?

What you are talking about should be standard bricks, 240 * 115 * 53 The volume of each brick (240 * 115 * 53) = cubic meters (the gross consumption is calculated according to its volume), and we are now calculating the net consumption, plus 1% loss. That's the actual amount, 120 walls. **Cubic metre.

Then 120 bricks per square meter of the wall are about 64 bricks.

180 walls. **Cubic metre.

Then 180 bricks per square meter of the wall are lost about 96 bricks.

240 walls. **Cubic metre.

Then 240 bricks per square meter of the wall are about 128 bricks.

Subtotal, 115 walls per square 64 pieces. 180 walls are 96 blocks per square meter, 240 walls are 128 blocks per square meter, (the ash joint is 1 cm according to the national standard).

The standard size of clay brick is 240*115*53. Remember that 1 meter is 16 floors, and the 120mm wall has four pieces per meter, and one square meter is 64 pieces. The 240mm wall has eight pieces of one meter per floor, and 128 pieces per square meter.

The 370mm wall has 12 pieces per meter per floor, and 192 pieces per square meter. The 500mm wall has 16 pieces per meter per floor, and one square meter is of course 256 pieces. You slowly understand these numbers, and you can calculate them yourself, without asking others.

As for the 180mm wall you said, you can calculate it like that, a 120mm thick wall plus half of the 120mm thick wall is 60mm thick, so the calculation is a 180mm wall, and one square meter is 96 pieces. The amount of each cubic meter is the same no matter how thick the wall is, it is 512 pieces. If you are calculating the quantity, if you are making a budget, then there is a loss in the quota, and the engineering quantity is multiplied by the amount contained in the quota.

Depending on what kind of brick you are talking about, the red brick is 240x115x53, and the 24 wall I remember is 512 pieces per cubic meter.

What should be paid attention to in the design of masonry structure about the wall?

About the wall problem: the horizontal support of the wall of the stairwell is weak, the top wall is higher, at 8 degrees and 9 degrees, the horizontal wall and the outer wall of the top stairwell should be along the wall height every 500 to set 2 6 of the length of the hidden digging of the middle reinforcement, 9 degrees, at the rest platform should be added a steel belt. On the top floor, in order to prevent cracks in the wall, the following measures can be taken:

The insulation layer polystyrene board is thickened by 45. In order to prevent the polystyrene board from being stepped on during construction, cement polystyrene board can be used instead of ordinary polystyrene board.

The ring beam is heightened, and the diameter of the longitudinal bar is increased. Erect the thermal insulation layer, do not use the cast-in-place slab with prefabricated slabs (in order to solve the overhanging eaves anti-overturning) method. All the top gables and the end of the longitudinal wall (the width is the width of the building, the range of the stove hill b 4) are reinforced with reinforcement mesh pieces in the range above the lintel.

When the length of the wall from the structural column to the opening is less than 300, it should be made of concrete, otherwise it is difficult to build masonry.

Walls of small sections (<600) such as walls between windows should be made of concrete. Otherwise, the wall cannot be built or the compressive strength is not enough. Note:

In the brick-concrete structure (especially 3 floors and below), part of the transverse wall can be canceled and replaced with a light partition wall to reduce the self-weight and force, reduce the foundation excavation, and also facilitate the free separation of rooms in the future, without having to be a brick wall for each wall. The local size limit of multi-storey masonry houses is too strict, and it is difficult to meet the general engineering, so it can be relaxed after the addition of structural columns.

Horizontal and vertical, the mortar is full, and the lap is staggered.

Specification requirements: 1. The strength grade of bricks must meet the design requirements;

2. The strength grade of the mortar must meet the design requirements;

3. The corners and junctions of the brick masonry should be masonry at the same time, and it is strictly forbidden to divide the internal and external walls without reliable measures.

4. The brick-concrete structure should be left with horse teeth. The retention should be correct, and the tie ribs should be set at 50cm intervals;

5. The fullness of the mortar should be greater than 80%;

6. The axis displacement should not be greater than 10mm;

7. The verticality deviation should be less than 10mm;

8. The thickness of the horizontal ash joint should be controlled at 8-12mm

9. The surface flatness should be controlled within 8mm;

10. The width of the door and window openings should be controlled within plus or minus 5mm.

11. The straightness of the horizontal ash seam should be controlled within 10mm.

General requirements for masonry walls: horizontal and vertical, full mortar, lap staggered joints.

Specification requirements: 1. The strength grade of bricks must meet the design requirements;

9. The surface flatness should be controlled within 8mm;

10. The width of the door and window openings should be controlled within plus or minus 5mm.

11. The straightness of the horizontal ash joint should be controlled within 10mm, and the specific requirements of the masonry specification should be read.

It is to build a section of the corner of the wall according to the wall line and the number of skin rods made, so as to facilitate the hanging line masonry to build a large wall.
