How to build an empty bucket wall, and what are the requirements for the masonry of an empty bucket

The empty bucket wall is to take the brick length as the wall thickness, the bricks are symmetrically erected on both sides of the wall, and then two bricks are erected at both ends of the bricks according to the direction of the wall thickness, a space of 24 * 12 * 12 cm is formed between the four bricks, three bricks are built along the side along one end as the law, and the same empty bucket is formed, so repeatedly a layer of the empty bucket wall is formed, after a layer is built, a layer (6 cm) of bricks is laid flat on the top of the empty bucket according to the wall thickness direction (24 cm).

Then build a second layer of empty buckets on top. Layers of hollow bucket walls have been built up. The masonry joints of all the above walls must be staggered, and there is a certain masonry skill, which must be learned by the craftsman as an apprentice.

A brick wall does not comply with any of the rules and regulations for masonry, and it can also be a wall made of broken bricks.

The empty bucket wall is made of ordinary clay bricks mixed with cement mortar or lime mortar, forming a regular empty bucket in the wall. Generally, it can be made of sleepless empty buckets, one sleep, one sleep, two buckets, and three buckets; Due to the production of clay bricks, a large amount of farmland has been destroyed, and houses built with empty bucket walls are not earthquake resistant. Therefore, the traditional "Qin bricks and Han tiles" have been gradually eliminated.

You ask how to build the empty bucket wall, this question is not very good, because this kind of problem is better to be demonstrated on the spot to be clearer:

1. The empty bucket wall is a wall with a hollow structure built sideways with standard bricks.

2. There are four masonry methods for the empty bucket wall: one sleep and one bucket, two sleep and one bucket, three sleep and one bucket and full bucket wall.

3. In addition, as far as the bricks in the empty bucket wall are concerned, there are also two kinds of single Ding empty bucket and double Ding empty bucket.

1. The empty bucket wall is based on the length of the brick for the wall thickness, the brick is erected on both sides of the wall on the side of the finger beam, and then two bricks are erected at both ends of the brick according to the direction of the wall thickness, and a space is formed between the four bricks.

2. Lay a layer (6 cm) of bricks on the top of the empty bucket according to the wall thickness direction (24 cm). Then build a second layer of empty bucket on top. Layers of hollow bucket walls have been built up.

Note: The masonry joints of all the above walls must be staggered.

Due to its poor seismic performance, the empty bucket wall is rarely used in formal construction projects in the seismic fortification area, but because the empty bucket wall is a form of masonry after all, it is still sometimes used in the non-seismic area, what are the general requirements for the masonry of the empty bucket wall? The following is an introduction to the main content of the requirements for empty bucket wall masonry brought by Zhongda Consulting for reference.

1) The holes of various pipes and boxes need to be left in the empty bucket wall, which must be set aside during masonry, and it is strictly forbidden to cut and chisel after the masonry is completed. Otherwise, the masonry will be disturbed and the overall quality of the masonry will be affected.

2) The empty bucket wall should be built into solid masonry (flat masonry or side masonry) for the following parts

1) the corners and junctions of the wall;

2) All masonry below the indoor floor;

3) 3 leather brick parts on the indoor floor and floor surface;

4) The part below the elevation of the window sill on the ground floor of the exterior wall of the three-storey house;

5) the length of the 2 4 skin bricks under the supporting surface such as floor slabs, ring beams, joists and purlins. The strength grade of the mortar should not be less than;

6) the part of the beam and roof truss support according to the design requirements;

7) Within 240mm on both sides of pilasters and openings;

8) 2 leather brick sections under the eaves and gables;

9) Walls in stairwells, firewalls, overhangs, and walls with more flues and pipes;

10) When making an infill wall, the connection with the frame tie bar;

11) embedded parts;

12) The vertical joints of solid masonry and hollow bucket walls should be built on each other.

3) The deviation of the size and position of the empty bucket wall should meet the allowable deviation of the masonry structure. If the allowable deviation of the size and position of the brick masonry is exceeded, it must be dismantled and re-built, and it is not allowed to use the method of percussion and chisel to make corrections. The allowable deviation of the size and position of the empty bucket wall is the same as the allowable deviation and inspection method of the size and position of the brick masonry.

4) the joint of the wall surface of the empty bucket wall should be made of flat joint, and the grout mortar can be mixed with fine sand 1 of cement mortar.

5) Because the empty bucket wall is made of on-site masonry, its strength and stability often cannot meet the requirements of pouring concrete, which is different from small block masonry, therefore, it cannot be poured concrete in the empty bucket wall like a small concrete hollow masonry wide jujube block, as a core column to strengthen the seismic resistance of masonry.

Summary. There are two types of masonry methods for empty bucket walls: sleeping empty bucket walls and sleepless empty bucket walls (see figure). The bricks laid on the side are called bucket bricks, and the bricks laid on the flat are called sleeping bricks.

There is a sleeping empty bucket wall is every 1 3 skin bucket bricks to build a skin sleeping brick, respectively called a sleep and a bucket, a sleep and two buckets, and a sleep and three buckets. The sleepless empty bucket wall only lays bucket bricks and sleepless bricks, so it is also called the full bucket wall. No matter which masonry method, the vertical joints of the upper and lower bricks should be staggered to ensure the integrity of the wall.

The traditional empty bucket wall is mostly made of special thin bricks, and it is built in the form of a sleeping empty bucket. Some also fill the hollow part with broken bricks, slag, mud or grass mud to improve thermal performance. This kind of empty bucket wall is generally used as the outer parapet wall of a timber frame house.

The modern hollow bucket wall has been changed to ordinary bricks, and it is built into a sleepless hollow bucket wall and a double ding brick sleepless hollow bucket wall as a load-bearing wall and retaining wall for low-rise houses. The empty bucket wall has high requirements for the quality of the bricks, and the edges and corners are required to be intact, and the strength grade is not lower than the number. The mortar should have good workability, so that the ash joints are full after masonry, and the commonly used grade is not less than No. 25 mixed mortar.

Hello dear, <>

The empty bucket wall can be added with columns, and the empty bucket wall is very dangerous without columns, not strong, and easy to collapse. 1.Addition of structural columns:

A reinforcement measure to enhance the stiffness of the house and prevent the collapse of the house, the four corners of the external wall, the junction of the transverse wall and the external longitudinal wall of the staggered part, the two sides of the larger opening, and the junction of the inner and outer walls of the large room, the structural column must be closely connected with the ring beam and the wall in the general setting. 2.Set up the ring beam:

The effect increases the overall stiffness and stability of the house, reduces the damage to the house caused by the uneven settlement of the foundation, and resists the impact of the first force. Set location: The roof must be set, the floor slab is set up at the partition, and when the foundation is not good, the practice should also be set on the top surface of the foundation, and the reinforced concrete ring beam has the same width as the wall. 3.

Addition of door buttress: to ensure the stability of the wall and the installation of the door frame. Door buttresses should generally be set up in the door opening, especially at the turning point of the wall or the T-shaped wall, and the width of the wall should be constructed.

4.When the core column of the hollow block wall is made of concrete hollow block, the core column should be set at the four corners of the house, the corner of the outer wall, and the four corners of the stairwell. Hope mine is helpful to you.

Hollow flower wall is a kind of hollow wall structure, which refers to the wall made of bricks into various hollow fancy walls.

Empty bucket wall refers to the empty positive wall built with brick side masonry or flat and side alternate masonry, which is an excellent light wall, compared with the ordinary solid wall of the same thickness, it can save bricks, mortar and labor, and at the same time because of the formation of air barrier in the wall, it improves the thermal insulation and thermal insulation performance.

The empty bucket wall can be used to build 1 3-storey civil dormitories, residences, canteens, office buildings, etc., and can also be used for the envelope structure of industrial buildings, the exterior walls of workshops and warehouses with low vibration.

The empty bucket wall can be slotted, but it is necessary to pay attention to the following points of waiter return: 1The structure and strength of the wall should be considered in the position of the trench trough, and the load-bearing function of the wall should not be damaged.

2.The slotting should be smooth and straight, and there should be no dislocation, oblique lines and other problems. 3.

Before slotting, the position and size should be determined, and the required size should be made at one time to avoid repeated slotting, which will affect the stability of the wall. 4.After slotting, the debris in the groove should be cleaned up in time to avoid affecting the service life and safety of the wall.

It is recommended that you consult a professional before grooving to ensure the safety and quality of construction.
