How to set up the structural column? What are the requirements for the setup of structural columns?

The setup of the construction column.

1. When there is no frame column at the corner of the wall, and at the junction of the wall of different thicknesses, structural columns should be arranged.

2. When the wall length is more than 5m (or the wall length is more than 2 times the height of the storey), a structural column should be set in the middle of the wall length (at the edge of the hole in case of a hole).

3. Structural columns should be set on both sides of the larger opening and at the end of the unconstrained wall.

4. The structural column and the wall tie bar are 2 6@500, which are connected along the full length of the wall.

It is mainly determined according to the design requirements of the drawings.

The setup of the construction column.

1. When there is no frame column at the corner of the wall, and at the junction of the wall of different thicknesses, a structural column 2 should be set up, and when the wall is longer than 5m (or the wall length is more than 2 times the height of the floor), the structural column should be set in the middle of the wall length (at the edge of the hole in case of a hole).

3. Structural columns should be set on both sides of the larger openings and at the end of the unconstrained wall 4, and the structural columns and the wall tie bars are 2 6@500, and the full length of the wall is mainly determined according to the design requirements of the drawings.

Structural columns. The setting requirements are: multi-storey houses of verandah type and single-sided corridor type should be added according to the number of floors of the house, and then the structural columns should be set according to the requirements of the following table, and the longitudinal walls on both sides of the single-sided corridor should be treated as exterior walls.

For houses with fewer horizontal walls, the number of floors should be increased according to the number of floors of the house, and then the structural columns should be set according to the requirements of the following table. When the house with fewer transverse walls is an outer corridor type or a single-sided corridor type, structural columns should be set up according to the requirements of paragraph 2 of Article 2 at the same time; However, when 6 degrees does not exceed 4 layers, 7 degrees does not exceed 3 floors, and 8 degrees does not exceed 2 floors, it should be treated as the number of additional floors.

For houses with few horizontal walls on each floor, structural columns should be set according to the number of floors with two additional floors. Autoclaved sand-lime bricks are used.

masonry house, when the shear strength of masonry.

When only 70% of the ordinary clay brick masonry is reached, the structural column should be set according to the number of layers of the additional layer according to the requirements of paragraphs 1-4; However, when 6 degrees does not exceed 4 layers, 7 degrees does not exceed 3 floors, and 8 degrees does not exceed 2 floors, it should be treated as the number of additional floors.

1.The door and window openings are provided with frame posts, thickness 100mm, configuration 2 12, and hook 6 200. When the width of the door and window opening is 2100mm, the reinforcement of the frame column extends into the lintel, ring beam and reinforcement belt.

When the width of the door and window opening is 2100mm, the reinforcement of the frame column extends into the beam or the slab. The cross-section of the structural column is the wall thickness * 200, and the structural column and the roof are connected with the structural construction when reserving 12 steel bars and the main reinforcement lap length binding, and the structural column is connected with the roof lower beam, the plate, and 16 steel bars and the main reinforcement lap length are reserved when the structural construction is adopted.

2.The structural columns should be aligned up and down along the height of the entire building, and the structural columns should not be misaligned with each other between the layers. The stairwells, elevator halls, and structural columns protruding from the roof should extend to the top and be connected with the top ring beam and pressure belt.

The thickness of the concrete protective layer of the structural column should be 20mm and should not be less than 15mm.

3.Reinforced concrete structural columns must be set up for concrete block masonry, and structural column tie reinforcement must be set in the process of wall masonry, and horse teeth must also be built. Starting from the base of each layer, it retreats first and then advances to form a concave and convex opening that is 100mm wide and 200mm high.

The tie ribs of 2 6 are used between the column walls, and the spacing is 400 600mm.

4.After the reinforcement of the structural column is tied, the wall should be built first, and then the concrete should be poured. Structural columns should have exposed surfaces.

5.Before the formwork is erected, the steel skeleton must be concealed engineering inspection, the weak layer of the mortar on the original concrete surface of the joint should be chiseled, the debris at the root of the column should be cleaned up, and the suffocation of the cane pin should be washed away with pressure water. When the structural column formwork is erected, it is required that the formwork on both sides of the structural column must be close to the wall, the support is firm, and the slurry leakage of the plate joints is strictly prohibited.

Before pouring concrete, the masonry and the wooden formwork must be watered and moistened, and then poured with the same 50mm thick cement mortar as the concrete ratio, and the concrete is required to be poured and vibrated in layers, and the thickness of each layer is 400mm, so as to ensure that the axillary concrete of each layer of concave jaw is vibrated and compacted, and then the next layer of concrete is poured until it is completed.

When the length of the straight section without concrete wall (column) separation exceeds 120 or 100 thick walls, and the 180 or 190 thick wall exceeds 5 m, concrete structural columns need to be added to separate the section.

120 or 100 thick wall, when the wall height is not more than 3 meters, the width of the opening is not greater, if it is not satisfied, structural columns or reinforced concrete horizontal tie beams should be added.

180 or 190 thick wall, when the wall is not more than 4m, the width of the opening is not than, when it is not satisfied, structural columns or reinforced concrete horizontal tie beams should be added, when there is no frame column at the corner of the wall, and at the junction of the wall of different thicknesses, structural columns should be set.

The advance and retreat dimensions of the horsetooth.

1. The first retreat and then the first advance refers to the first 300 mm height of the horsetooth, the first bricks should be laid on the outside of the column, and the bottom should be retreated first to ensure the stability of the root of the structural column.

2. Bending is easy to affect the anchoring effect or damage the steel bar, so every 300 high will retreat 50 mm or 50 mm. Because the structural column is generally rooted in the concrete foundation or ring beam, the root is the concrete masonry concrete block.

3. The lower part is made of 200 mm high cement bricks, which has higher strength than blocks and better moisture-proof; The junction between the top and the beam plate should be densely built with cement brick oblique masonry, and the orange oblique masonry is the brick oblique vertical masonry, so that it can be solid. The main purpose is to make the wall and the structural column more firmly combined when pouring the structural column, which is conducive to seismic resistance.
