The problem of column network layout, the principle of column network layout

The column spacing is determined by the area of a medium room, such as basement parking, it is necessary to integrate the layout of the parking space, and consider it comprehensively, so that it is more economical.

First, the problem of column network layout.

The column spacing is determined by the area of a medium room, such as basement parking, it is necessary to integrate the layout of the parking space, and consider it comprehensively, so that it is more economical.

Now it's basically 6-8 meters between adjustments. Of course, we have to think about the force. But this 6-8 meters, already taking into account these contents. It doesn't hurt to just take it and use it.

2. What are the forms of column grids?

Rectangular column grid, the most reasonable and economical. It is also possible to be non-orthogonal, but the rooms made are not rectangular anymore, and the usage rate is low.

Triangle. The building made of the column network has poor applicability and is not good under stress.

When facing a special-shaped plane, what should I do if a set of column nets cannot meet it? Are multiple column spacings allowed? Multiple axes?

The column grid can be more than one set, try to reduce the number of sets. For example, office buildings, corridors and rooms can use different column nets.

Or is it a problem of special-shaped planes, how to deal with irregular building contours that are not orthogonal to the axis of the column network? For example, because of the ground.

Shape limit, the building has an acute angle, how to arrange columns? Is it okay to have a triangular column grid? Or do you have to use a rectangular column network, and what to do with that corner?

Let's arrange it according to local conditions. When arranging the building, you can ignore the corners for the time being, or ask the structural professional to help you.

Communicate with multiple disciplines.

This is simple, it is recommended that you read Peng Yigang's spatial combination theory, high-rise building design and technology, etc.

1. The determination of the column network is set up according to the requirements of the room use area and the economy of the structure, and at the same time, the lighting requirements of the building should be taken care of. The usable area of the room is determined by the activities of the user and the size of the home.

2. In addition, the setting of the column network should also consider reducing the difficulty of construction, economy, the efficiency of the use of room area, etc., so the irregular column network should be avoided as much as possible.

3. The larger the spacing between the column grids, the thicker the columns will be, and the higher the beams will be, which will have a certain impact on the height of the windows.

4. When learning the design at the beginning, we should start with simplicity, try to practice the basic skills on the basis of the rectangular column network, and then involve the complex column network problems. The arrangement of the column network should also be combined with the architectural modeling. In the design, there are also complex column grids that are set up to discard a small part of the usable area for the needs of modeling.

Architects generally use experience when arranging column grids, such as: 7800 for hotels, 9000 for offices, 9000 for schools, etc.

The main principles are as follows:

1.Try to arrange the wall according to the construction specialty;

2.Try to make the columns uniform in the longitudinal and horizontal directions, and the longitudinal and horizontal spacing should be as close as possible, so as to arrange the beams and slabs more reasonably;

3.Try to reduce the beam section (but consider whether to save money by setting columns or reducing columns, that is, it is better to increase columns or increase beams);

4.For the construction profession to save space as much as possible, often the building floor height is certain, your beam is larger, it will reduce the height of the beam (or ceiling) and the architectural profession to fully discuss;

5.It is cost-effective to set up beams or use plates (ribs, etc.) (from the economy, use, safety and other aspects of full consideration, compare the most reasonable.)

1.Column grid - the arrangement of frame columns in two directions vertically and horizontally on a flat surface.

2.The task of column grid arrangement - to determine the arrangement of columns and the column spacing.

3.The basis of the layout - to meet the requirements of the building, while considering the rationality of the structure and the feasibility of the construction.

The principle of column network layout refers to the reasonable arrangement of column network according to the structure and function of the building in the architectural design, so that it can meet the load-bearing requirements of the building, and at the same time meet the space needs and aesthetic requirements of the building as much as possible. The specific principles are as follows:1

The column network layout should consider the structural form and load characteristics of the building, and reduce the number and size of columns as much as possible to improve space utilization and aesthetics. 2.The layout of the column network should consider the function of the building, and the column network should be reasonably arranged to meet the requirements of space separation, ventilation and lighting of the building.

3.The column network layout should consider the use effect and comfort of the building, and arrange the column network reasonably to ensure the stability and safety of the building, and at the same time reduce the impact of the column as much as possible. 4.

The layout of the column network should consider the aesthetic requirements of the building, and arrange the column network reasonably to ensure the overall image and style of the building, and at the same time reduce the visual impact of the column as much as possible. 5.The layout of the column network should consider the construction and maintenance requirements of the building, and the column network should be reasonably arranged to facilitate the construction and protection of Weibihu, and at the same time reduce the difficulty of the construction and maintenance of the column as much as possible.

Large column mesh: Advantages: large column mesh can obtain large column-free space, flexible space separation, and convenient indoor layout.

Non-load-bearing partition walls can be built between columns to arbitrarily separate the space. It can also be balanced without building any walls, creating an open office space or a public space. It is conducive to the layout of large-scale equipment and effectively improves the utilization rate of industrial construction area.

Disadvantages: high cost, high beams, the same floor height to obtain the net height. Columns:

Advantages: low cost, small beams, unified modulus, convenient construction, cast-in-place reinforced concrete, stable structure, good seismic resistance. Cons:

The small column net can obtain a small column-free space, such as the application in the garage requires high requirements for parking, and the turning angle is limited.

It can be different, if you design a hotel standard floor, it can only mean that there is a problem with the building plan. The data of different column spans has a great impact on the ground floor as well as the underground.

The size of the column network is determined by the column spacing and span. The determination of the plant column network is to determine the span and column spacing. The design of single-storey industrial plants in China mainly adopts prefabricated reinforced concrete structures.

system, the basic column spacing is 6m. When the structure is brick-concrete.

The column spacing should be less than 4m when the system is system, which can be ,.

The column network arrangement is a frame structure.

A part of the column network is arranged, the frame column is arranged in both directions in the vertical and horizontal directions on the plane, and the task of column network layout determines the arrangement form and column spacing of the column, and the basis of the layout should meet the requirements of building use, and the rationality of the structure and the feasibility of construction are considered at the same time. The multi-layer frame mainly bears the vertical load, and the uniformity of the internal force distribution of the structure should be taken into account when the column network is arranged.

The mid-span moment of frame A under vertical load for two frame structures.

and the bending moment of the support are larger than that of frame b.

Therefore, the amount of material used is also more than that of the B frame. The arrangement of the longitudinal columns also has an impact on the structural stress, and the frame column spacing can generally be taken from the building bay. However, if the bay is small and the number of layers is small, the reinforcement of the column section is often determined according to the structural requirements, resulting in the material strength can not be fully utilized.

At the same time, the column spacing is too small to make it difficult to flexibly arrange the building plan, so it can be considered to remove a row of columns and take the column spacing into two bays. to hotels, office buildings and other civil buildings.

The column network layout should be coordinated with the layout of the building separation wall, and the columns are generally located at the intersection of the vertical and horizontal walls, and the size of the column network is also limited by the beam span, which is generally between 6 and 9m.

It can be directly opposed, but generally speaking, the column network layout should be symmetrical and regular, which is convenient for the calculation of the structure, and the column distance is about 8 meters.
