Product Description
Strong bearing capacity: Steel has excellent mechanical properties, and its strength is much higher than that of traditional building materials such as brick, stone, concrete, etc. This enables steel structure buildings to withstand greater loads, such as high-rise buildings, long-span bridges, large industrial plants and other buildings with high bearing capacity requirements, and steel structures can well meet the demand. For example, when building a large stadium, the steel structure can easily achieve a large-span spatial layout to provide an open and unobstructed view for the audience.
Light weight: Despite the high strength of steel, the dead weight of steel structure buildings is relatively light. This is because the steel structure adopts a reasonable cross-sectional shape and arrangement, which can minimize the amount of steel under the premise of ensuring the strength and stability of the structure. Compared with traditional concrete buildings, steel buildings can generally reduce their weight by 30% to 50%. For example, in the construction of super high-rise buildings, the advantages of light weight of steel structure are particularly obvious, which can greatly reduce the load of foundation engineering and reduce the cost and difficulty of infrastructure construction.
Component factory prefabrication: Most of the components of steel structure buildings are prefabricated in factories. Factory production has the characteristics of high precision and high efficiency, and can be produced in strict accordance with the design requirements and standards to ensure the stable quality of components. At the same time, the production equipment and technology in the factory are relatively advanced, which can achieve large-scale and mass production and greatly improve production efficiency.
On-site rapid assembly: After the prefabricated steel structural components are transported to the construction site, they are quickly assembled using mechanized construction methods. The connection methods of steel structure mainly include welding, bolt connection, etc., which are relatively simple to operate and can complete the connection and fixing of components in a relatively short time. Compared with the traditional concrete structure building, the on-site construction of the steel structure building has less wet work, and there is no need to carry out a large number of concrete pouring, maintenance and other work, which greatly shortens the construction period
Large-span space: The steel structure has good mechanical properties and structural stability, and can achieve a large span. In architectural design, the long-span spatial structure can provide an open, column-free interior space for the building to meet the needs of different building functions. For example, in large public buildings such as exhibition halls, gymnasiums, and terminals, the application of steel structure large-span space is very extensive. Taking the exhibition hall as an example, the large-span steel structure space can be easily used for exhibition layout, display various large-scale exhibits, and also provide a spacious and comfortable visiting environment for the audience.
All construction surveyors must be licensed, if any replacement must be agreed by the technical person in charge of the site is responsible for the transfer to ensure the normal construction of the project.
Familiarize with the drawings (general plan, axial plan, foundation plan, deepen the detailed drawings), to understand the design intent, to fully grasp the axis, dimensions, elevation and site conditions, the relevant dimensions of the design of the paper and the measurement of the setup of the data should be carefully calibrated.
Measurement control point handover and rechecking.Before the steel structure construction unit enters the construction site, it should retest the plane control network and elevation control points of the building construction (coordinates and elevation control points are provided by the owner or the general contractor). According to the requirements of the construction progress plan, the measurement program, the measurement method, the calculation of the measurement data and the drawing of the measurement sketches.
1) Review the drawings carefully when you get them and check whether the location of anchor bolts crosses the reinforcement in the foundation column and whether there are any other construction contradictions.
2)After acceptance of foundation reinforcement binding, install the anchor bolts.
3) Check the hole position and hole diameter of the positioning steel plate one by one after the positioning steel plate is delivered to the site, and do not meet the requirements.
4) Reasonable arrangement of the installation sequence, has entered the site of the anchor bolts to do a good job of protection and storage.
5) In the construction should pay attention to the tying of bearing steel (or foundation steel) after the completion of the installation of anchor bolts.
6) The installation of anchor bolts should be carried out after the completion of the installation of anchor bolts.
7) The installation of anchor bolts should be carried out after the completion of the installation of the anchor bolts.
The elevation point of Shi 0.000 is provided by the owner or the general contractor to provide the elevation control point set at the site, and the elevation control point of the building construction is retested before the construction of the steel structure.
Bolts require uniformity of threads, thread length, leakage size and verticality to meet the design requirements and specification requirements.After the bolts enter the construction site by the constructor for acceptance, check the bolt factory certificate, test report, specification size, quantity, wire buckle length is in line with the design requirements, acceptance of qualified according to the specifications of the yard neatly, and do a good job of marking.
Steel girder assembling is used for larger span truss, light steel structure, section 1, H, mouth type mostly, the connection method has three forms of high-strength bolts, bolt welding combination and welding.Portal steel frame, variable cross-section inclined beam or multi-section, solid web welded I-beam cross-section or light H-section, portal steel frame inclined beam is divided into several units according to the transportation conditions, and the units can be connected with high-strength bolts through the end plates.
For the sake of structural stability, easy calibration and accurate installation, for multi-storey structural floors, the top beams should be fixed first, then the lower beams, and finally the intermediate beams.When the installation of columns and beams in a frame is completed, measure and correct this in time.
