The steel structure column is connected with the embedded parts of unknown size

On this issue, there are the following suggestions:

The size of the embedded part is unknown, which means that you do not know the length, width, thickness and other dimensions of the embedded part?

If so, this question should definitely be raised with the design unit, who will provide additional dimensions for the embedded parts.

The size of the embedded parts is unknown, and the embedded parts cannot be processed, how to do the construction process of the embedded parts?

The cross-sectional size of the steel structure column will be smaller than the size of the embedded parts, and the size of the embedded parts is usually greater than the cross-sectional size of the column by more than 50mm on each side. <>

Hello, first look up the steel structure specification, the structure basically belongs to the light steel structure, the embedded foundation can be in accordance with the design atlas plus the civil design atlas for reference, if the foundation pit should be in depth of about 1 meter to the meter width of about meters, the length of about meters, the size of the embedded plate can be defined in accordance with the size of the structural column floor of this shed, 50 mm to 80 mm wider than the length and width of the steel column bottom plate, because its connection is convenient for construction. Hope it helps, thank you.

The structure basically belongs to the light steel structure, the embedded foundation can be in accordance with the design atlas plus the civil design atlas for reference, I personally think: the foundation pit should be in depth of about 1 meter to meter width of about meters, length of about meters, the size of the embedded plate can be defined in accordance with the size of the structural column floor of this shed, wider than the length and width of the steel column bottom plate of about 50 mm to 80 mm, because its connection is convenient for construction.

Again: the depth of the foundation must be more than the winter ground permafrost in your region.

Kiss! Hello, happy to answer your <>

How to fix the columns of the two embedded parts of the steel-friendly structure is as follows: 1. The measurement and positioning control line of the embedded parts should be set separately, and the control line of each embedded part should be separately measured from the structural control axis, and the control marks should be made on the surface of the poured concrete or fixed steel bar. 2. The embedded parts should be marked with the center positioning mark before installation, so as to facilitate the measurement and correction during installation.

3. When there is a conflict between the anchor bar of the embedded part and the position of the main reinforcement of the structure, the wheel can adjust the position of the anchor bar appropriately to ensure the installation position of the embedded part. When there is a conflict between the position of the embedded screw and the main reinforcement, the position of the main reinforcement should be adjusted as much as possible to ensure that the screw is in place according to the design position. 4. The embedded parts and structural reinforcements can be fixed by binding or spot welding with stirrups, and the welding of embedded parts and the main reinforcement of the structure should be avoided during construction.

The temporary positioning measures should be reliable and firm, and can resist certain construction loads. 5. The relative position of the embedded bolt of the same column base should be fixed by the template, and the template can be made of channel steel bracket or steel plate with precise holes, and the template and the screw rod should be fixed with a nut, and spot welding or welding positioning shall not be carried out. During installation, the position of the bolt group is controlled by controlling the position of the center point of the template and the direction of the center line of the template.

6. After the embedded parts and embedded bolts are positioned, the position of the embedded parts and embedded bolts should be tracked and measured before the concrete pouring and in the process of pouring vibration, and the corresponding correction measures should be formulated. 7. After the concrete is poured to a certain strength, the positioning plate or positioning bracket should be removed. Hope mine can help you <>

Do you have any other questions?

The shelving of the steel structure column is related to the lap size and the use requirements of the steel structure, and the following factors are mainly considered: 1Bearing capacity:

The lap joint and shelving of the steel column need to meet the requirements of the structural load, and generally Pi Xun needs to increase the lap length to improve its bearing capacity when bearing heavy loads. 2.Stability:

The lap and shelving of steel columns need to consider their stability, and generally need to keep a certain distance to prevent the column from being unstable when subjected to force. 3.Material Saving:

When designing steel structures, it is necessary to consider the efficiency of material use, so the length of general lap joints and shelving should be shortened as much as possible to save materials and reduce costs. Generally speaking, the lap length of the steel structure column should not be less than the multiple of the column diameter, and the shelving length should not be less than 3 times the column diameter. The specific size also needs to be considered and designed according to the specific fuel width.

In addition to the material, diameter and size of the bolt itself, the most important thing is that the elevation and plane position should meet the requirements of the drawing, and the error is allowed by the specification. 1. The material of the bolt conforms to the design. 2. The specifications, quantity, length, etc. are in line with the design.

3. The embedded position conforms to the design. 4. The construction meets the process requirements. At present, the weak links in the construction quality are mainly manifested in:

l) high-strength bolts are shoddy, (2) high-strength bolt connection surface treatment does not meet the requirements of the specification, including surface treatment, smooth and dense pasting, bolt hole quality, etc.; (3) The screwing of high-strength bolts is not carried out in accordance with the provisions of the specification, such as being completed at one time without initial screwing and final screwing, without torque wrenches, and relying on subjective estimation. In order to ensure the construction quality of high-strength bolt connection project, the supervision engineer must have a high sense of responsibility, while urging the contractor to improve quality awareness, strengthen quality management, and implement quality assurance measures, and actively adopt working methods such as side station supervision and parallel inspection, only in this way can the construction quality of high-strength bolt connection project be under strict control.
