What are the setup requirements for structural columns, and what are the setup requirements for stru

If the drawings do not indicate that it can be set according to the requirements of the specification, the general wall length is more than 4m and structural columns must be added.

1. When the length of the straight section separated by no concrete wall (column): 120 (or 100) thick wall exceeds, and 180 (or 190) thick wall exceeds 5m, concrete structural columns are added in the interval.

Separate. (or 100) thick wall: when the wall height is less than or equal to 3 meters, the width of the opening is less than or equal to, if it is not satisfied, structural columns or reinforced concrete should be added.

Horizontal tie beams. (or 190) thick wall: when the wall height is less than or equal to 4m, the width of the opening is less than or equal to, if it is not satisfied, a structural column or reinforced concrete horizontal tie beam should be added. There are no frame columns at the corners of the wall.

At the junction of walls of different thicknesses, structural columns should be arranged.

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

Precautions for Structural Column Settings:

Structural columns should be associated with ring beams.

Connections, longitudinal reinforcements of structural columns.

The ring beam should be passed through to ensure that the longitudinal reinforcement of the structural column runs through up and down, only in this way can the overall rigidity be really increased, and the role of the structural column and the ring beam can be played, and it should be known that the structural column is generally designed at the four corners of the room, the four corners of the staircase, and the corners of the house.

In addition, the design number of structural columns, generally according to the height of the house, the pressure at the bottom or whether the local conditions belong to the multi-town area, etc., once to ensure the quality of the house, at the same time, it should be noted that if the structural column is set at the four corners of the outer wall, it is necessary to stretch a bay on the outer wall, and in other cases, the outer longitudinal wall and the corresponding transverse wall should be pulled through, and the height of the cross-section should be greater than or equal to four skin bricks.

There are normative requirements, as follows:

First, the setting of the structural column.

The regulations on the location of structural columns require that regardless of the number of floors and the intensity of the house, structural columns should be set at the four corners of the exterior wall, at the junction of the transverse wall and the external longitudinal wall at the staggered part, on both sides of the larger opening, and at the junction of the inner and outer walls of the large room.

Second, the structure of the structural column.

1.The structural column should be connected with the ring beam, and the longitudinal reinforcement of the structural column should pass through the ring beam to ensure that the longitudinal reinforcement of the structural column is connected up and down. For houses with ring beams on the compartment, reinforced brick belts should be set on the floors without ring beams.

Only when the structural columns are set at the four corners of the outer wall, a bay should be stretched out on the outer wall, and in other cases, the outer longitudinal wall and the corresponding transverse wall should be pulled through, and the cross-sectional height should not be less than the four-skin brick, and the mortar strength should not be lower than M5 grade.

2.The junction between the structural column and the wall should be built into a horsetooth, and should be along the wall height every 500 mm, set 2 6 Rachel reinforcement, each side extends into the wall not less than 1 meter or extends to the edge of the hole.

3.The minimum cross-section of the structural column can be 240 180 mm, the structural column of the four corners of the house can appropriately increase the cross-sectional size, the construction should be built first and then poured column, the concrete strength grade of the structural column should not be lower than C15, the steel bar grade is generally grade 1 steel, the thickness of the concrete protective layer is 20mm, and shall not be less than 15mm, and should not be greater than 25mm. The longitudinal reinforcement should be 4 12, the stirrup spacing should not be greater than 250mm, and the upper and lower ends of the column should be properly encrypted; More than 6 layers at 7 degrees, more than 5 layers at 8 degrees, 4 14 should be used for the longitudinal reinforcement of the structural column at 9 degrees, and the stirrup spacing should not be greater than 200mm.

At the junction of the ring beam and the structural column, the ring beam reinforcement should be placed on the inner side of the structural column reinforcement, that is, the structural column is regarded as the support of the ring beam, which is beneficial to the structure.

4.The structural column can not be set up separately, but should extend into the ground 500mm, it is advisable to set up a concrete seat with a thickness of 120mm at the root of the column, and the vertical reinforcement of the column is anchored in the seat, which is conducive to earthquake resistance and convenient construction. When there is a foundation ring beam, the vertical reinforcement of the structural column can be anchored in the foundation ring beam 50mm below the outdoor ground.

If the foundation ring beam is higher than the outdoor ground (the height difference between indoor and outdoor is large), the structural column should still be extended 500mm below the outdoor ground, and a concrete seat with a thickness of 120mm should be set at the root of the column. When the wall is attached to the pipe trench, the depth of the structural column should be greater than the depth of the trench.

3. Reinforcement of structural columns.

1.The longitudinal reinforcement of the structural column should not be less than 4 12, and the side column and corner column should not be less than 4 14. When seven degrees are more than 6 layers, when 8 degrees are more than 5 layers, and when 9 degrees are longitudinal reinforcement should be used 4 14.

The diameter of the vertical stressed steel bar of the structural column should not be less than 16mm. The vertical stressed reinforcement of the structural column should be anchored in the foundation beam and the floor ring beam, and should meet the anchorage requirements of the tensile reinforcement.

2.The minimum diameter of the stirrups of the structural column is 6, the spacing should not be greater than 250mm, and the stirrup spacing is encrypted to 100mm within the range of the upper and lower ends of the column greater than or equal to H 6 (h is the layer height) and greater than or equal to 450mm.

The requirements for the setting of structural columns are divided into the following situations: involving masonry structures, frame infill walls and seismic design.

Kiss, <>

We are glad to answer the requirements for the setting of structural columns: when the length of the straight section without concrete wall (column) separation, when the thickness of 120 (or 100) thick walls exceeds 5m, and the thickness of 180 (or 190) walls exceeds 5m, concrete structural columns are added to separate the section; 120 (or 100) thick wall, when the wall height is less than or equal to 3 meters, the width of the opening is less than or equal to, if it is not satisfied, the structural column or reinforced concrete horizontal tie beam should be added; 180 (or 190) thick wall, when the wall height is less than or equal to 4m, the width of the opening is less than or equal to, if it is not satisfied, structural columns or reinforced concrete horizontal tie beams should be added; In order to enhance the integrity and stability of the building, the reinforced concrete concrete structural column should also be set in the wall of the multi-storey brick-concrete structure building, and be connected with the ring beams of each layer to form a space frame that can resist bending and shearing, which is an effective measure to prevent the collapse of the house. Answer: The structural columns are set at the four corners of the exterior wall, the junction of the horizontal wall and the outer longitudinal wall at the staggered part, on both sides of the larger opening, and at the junction of the external wall of the large room.

In addition, the number of floors and the intensity of the house are different, and the requirements for the setting of structural columns are also inconsistent. The minimum cross-sectional size of the structural column is 240mm 180mm, and the vertical reinforcement is mostly used 4 12 stirrup spacing is not more than 250 mm. Hope mine can help you!
