Finding a Construction Organization Design Case of a Brick Concrete Structure 15

As follows: 1. Two-way load-bearing of longitudinal and horizontal walls: it can meet the needs of flexible space combination, and the space stiffness is large.

2. Longitudinal wall load-bearing: there are fewer transverse walls, which can meet the requirements of larger spaces, but the rigidity of the house is poor.

3. Transverse wall load-bearing: It is suitable for buildings with many transverse walls, small spacing and relatively fixed positions. The house has large spatial rigidity and good structural integrity.

4. Local frame load-bearing: the internal frame load-bearing and the surrounding wall load-bearing can meet the needs of large space, and the total stiffness of the house is mainly guaranteed by the frame.

The walls of a brick-concrete building are arranged as follows:

1. The transverse wall is load-bearing. Floors are supported by transverse walls parallel to the gables. It is often used in small buildings such as residences, dormitories, hotels, and office buildings with regular floor plans. The transverse wall doubles as a partition wall and a load-bearing wall, with a spacing of 3 4 m.

2. Longitudinal wall load-bearing. The eaves wall and the longitudinal wall parallel to the eaves wall support the floor, and the bays can be flexibly arranged, but the building stiffness is poor, and the façade cannot open a large area of doors and windows.

3. Mixed load-bearing of vertical and horizontal walls. Some of them have horizontal walls and some of them have longitudinal walls to support the floors. It is mostly used in buildings with complex planes and diverse internal space divisions.

4. Brick wall and inner frame mixed load-bearing. The interior is replaced by beams and columns instead of the wall load-bearing, and the outer retaining wall also plays the role of load-bearing. This arrangement allows for a large interior space with a flexible floor plan, but the stiffness of the building is insufficient. It is often used in large halls.

5. The bottom layer is a reinforced concrete frame, and the upper part is a brick wall load-bearing structure. It is often used for large spaces with shops on the ground floor or public activities on the ground floor, and residences, office buildings or dormitories on the top.

Several structural layout schemes and characteristics of brick-concrete structures are as follows: Transverse wall load-bearing system The load of the floor slab and roof slab is borne by the transverse wall. The floor load is transferred to the foundation through the floor slab, the transverse wall, and the foundation in turn. It is suitable for residences, dormitories, hotels, etc. with small room sizes.

Longitudinal wall load-bearing system dynamic load-bearing wall is mainly composed of longitudinal walls parallel to the length direction of the building. Put the girder or floor slab on the inner and outer longitudinal walls The floor load is transferred to the foundation through the floor slab, beam, longitudinal wall, and foundation in turn. It is suitable for offices, shops, and teaching buildings that require a large room for the use of space, and is also suitable for residences and dormitories.

Two-way load-bearing system The load-bearing wall is composed of a mixture of walls in both vertical and horizontal directions. This scheme has flexible building combination, good spatial rigidity, and a large amount of wall materials, which is suitable for buildings with many changes in bay and depth. Local frame system When the building requires a large space, the internal frame is used to bear the load, and the surrounding walls are load-bearing.

It is divided into transverse wall load-bearing scheme, longitudinal wall load-bearing scheme and longitudinal and transverse wall load-bearing scheme. The inner frame structure is basically eliminated

According to the load-bearing wall: 1. Longitudinal wall load-bearing. Transverse wall division or maintenance. It is more common in single-storey or residential buildings.

2. The transverse wall is load-bearing and the longitudinal wall is maintained. This is a commonly used form.

According to the structural form of the slab, it is divided into: 3. The brick wall, the structural column and the ring beam are combined, and the slab is prefabricated slab. is the more common form.

4. The brick wall, structural column and ring beam are combined, and the slab is cast-in-place plate.

The content of the construction organization design of brick-concrete structure includes the basis for the preparation of the project overview (mainly describing the construction of the project, the engineering architectural design overview, the engineering structure design overview, the construction equipment installation overview, the natural conditions, the engineering characteristics and the analysis of the project implementation conditions) construction deployment (mainly including the project management organization, project management objectives, general contracting management, various resources, the division of the construction flow section and the construction process), the construction plan of the main sub-projects, the construction preparation work plan, the construction plane layout, and the construction resource plan The construction schedule, measures to ensure the quality and safety of the construction, and environmental protection measures
