What should be paid attention to in frame infill wall masonry? 10

Vertical flatness, mortar marking. OK.

1. The masonry mortar should be mixed in advance, and the weight ratio should be used when mixing on site; And mechanical stirring should be used, and the material should be accurately measured by weighing.

3. The brick wall with structural columns should be built into a horsetooth, and the tie bar should be set according to the requirements of the construction specifications, and the concrete of the structural column should be carried out after the completion of the brick wall.

4. The masonry mortar should be mixed and used. The cement mortar must be used up within 3 hours after mixing; The mixed mortar must be used up within 4 hours after mixing; In summer, the high temperature is used up in 2 hours and 3 hours.

5. When building a brick wall, the clay bricks should be watered and moistened 1-2 days in advance, and should not be watered with the masonry or dry bricks on the wall.

6. According to the provisions of the mandatory standards: scaffolding eyes shall not be set within the range of the triangle with the lintel at an angle of 60 degrees on the lintel and within the height range of the net span of the lintel 1 2.

7. According to the provisions of the mandatory standards, the width of the window wall is less than 1m, as well as the scope of 200mm on both sides of the door and window openings and 450mm at the corner, no scaffolding eyes shall be left.

8. The net width of the temporary construction opening should not exceed 1m, and the Rachel reinforcement should be set up according to the requirements of the construction specifications.

9. The opening with a width of more than 300mm should be built into a flat arch or set up with a lintel. The surface of perforated bricks and hollow bricks shall not leave horizontal grooves.

10. Door and window lintels are constructed in strict accordance with the design requirements, and prefabricated concrete lintels must be preferentially used when the design drawings are unclear, and each side of the support is not less than 250mm. The window sills made of hollow bricks should be masonry according to the local regulations of each province to prevent cracks in the window masonry at a 45-degree angle.

11. The corners and junctions of masonry should be masonry at the same time, and it is strictly forbidden to separate masonry on the inner and outer walls without reliable measures.

12. The overall requirements of brick masonry are: upper and lower staggered joints, internal and external laps, full mortar, horizontal and vertical; The masonry error should be controlled within the allowable range of the code.

13. A gap of 2-3 cm should be reserved at the top of the filling wall, and only after the mortar is dry and the masonry is completely compacted (about 7 days) can it be squeezed with cement mortar or fine stone concrete and driven into the stone chips.

The frame structure is a high-order super-static structure, which bears both vertical and lateral loads, such as wind loads or horizontal actions. In general, the effect of the infill wall on the anti-side of the frame is not considered in the calculation, because the existence of the infill wall is uncertain in the use of the building, and the infill wall is often made of lightweight materials, or there is a gap between the column and the wall that is only connected by flexible reinforcement.

However, when the infill wall adopts a masonry wall and is rigidly connected with the frame structure, for example, the upper part of the masonry infill wall is fully "plugged" between the bottom of the frame beam, or when the construction sequence of the masonry wall is adopted first and then the pouring beam, then under the action of horizontal **, the frame structure will be laterally deformed, and the infill wall will play the role of an oblique rod. Under the action of horizontal **, the rigid infill wall has a great contribution to the lateral stiffness of the frame, and attention should be paid to making the overall lateral stiffness of the structure symmetrical as much as possible, so as to avoid excessive overall torsion.

Frame structure to fill the walls, it is recommended to use aerated bricks. Red bricks belong to clay bricks, in order to protect soil resources, its use has been restricted, and the density of red bricks is larger, the same volume is heavier, and the force on the old building is more affected, and the amount of steel used in the building under the same conditions will be some.

Most of the buildings now are frame structure or frame shear wall structure only rise, the wall in the middle of the frame structure beam and column is the filling wall, the filling wall is not load-bearing, it plays the role of enclosure and separation, the beam and column are the load-bearing role, and the masonry of the filling wall can be made of aerated concrete cherry blossom laughing block, perforated brick, lime sand brick, concrete block. The general frame structure, frame shear wall structure design artificially reduce the load of the superstructure, as long as the requirements of the building structure are met, most of them adopt the masonry with small bulk density, because the load reduction can save a lot of materials for the structure to the foundation, and the corresponding project cost is reduced.

Aerated concrete (aerated brick) has the advantages of light weight, good thermal insulation performance, good sound absorption effect, and has a certain strength and processability, and is widely used in construction as a filling and insulation material for enclosure structure. <>

Summary. Hello, it is a pleasure for you, dear, how to deal with the infill wall to the bottom of the frame beam, when the infill wall is built to the bottom of the frame beam, you need to pay attention to the following points: the bricks must be tightly connected with the frame beam to ensure the stability and reliability of the wall.

It is recommended to use reinforcement to connect frame beams and brick walls together. The rebar should be sunk into the concrete frame beam and through the wall bricks so that a tight physical connection is formed between the wall and the frame beam.

Hello, it is a pleasure for you, pro, how to deal with the infill wall to the bottom of the frame beam, when the infill wall friends shout to the bottom of the frame beam, you need to pay attention to the following points: the bricks must be closely connected with the frame beam to ensure the stability and reliability of the wall. It is recommended to make a good hail field with steel bars to connect the frame beams and brick walls in a single key.

The rebar should be sunk into the concrete frame beam and through the wall bricks so that a tight physical connection is formed between the wall and the frame beam.

Related extension: It is recommended to use waterproof materials and waterproof coatings at the bottom of the filling wall to prevent water from seeping into the wall from the ground and have a moisture-proof effect. After the masonry is completed, a small slope should be made on the surface of the brick bridge to avoid water accumulation on the wall.

Before building the wall, make sure that the surface of the frame beam is dry and clean. When the wall is built, it is necessary to clean the excess cement slurry on the surface of the brick wall to ensure that the brick wall is firmly connected with the frame beam. Min Feng.

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, the interval is separated by concrete structural columns;

2, 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 not satisfied, the structural column or reinforced concrete horizontal tie beam should be added;

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, the structural column or reinforced concrete horizontal tie beam should be added.

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.

Code for seismic design of buildings GB50011-2010.

Article: masonry infill wall in reinforced concrete structure shall also meet the following requirements:

When the wall is longer than 5m, the top of the wall and the beam should have a tie; When the wall length is more than 8m or the floor height is 2 times, it is advisable to set up reinforced concrete structural columns; When the wall height exceeds 4m, the half-height of the wall should be provided with a reinforced concrete horizontal tie beam connected with the column and penetrated along the full length of the wall.

If it is a frame structure and it is a hole in the infill wall, there is no problem with the impact on the strength of the structure, because the infill wall does not consider its load-bearing effect!

In fact, after opening the hole, add a column on both sides, and add a beam on it, and the construction can be done directly

Has the brick wall been laid and a hole of more than two meters has been opened?

The self-weight of the pipeline, except for the influence brought by the pipe support foundation, has no effect on the frame structure.

In the middle of the general description of the structure, the method of opening the brick wall can be. Lintel concrete grade, reinforcement, size, length of penetration into the brick wall.

Turn off the water and electricity, as long as you are safe, you can smash the interior wall casually.
