The Introduction

With the continuous progress of science and technology and the gradual improvement of urbanization level today, the related technology, machinery and materials of modern urban construction have also achieved a high level of development and improvement, which has laid a good foundation for the development of the construction industry.The scale and quantity of building construction are increasing, and the building forms are becoming more and more diverse. In the construction of some large construction projects, the structural design of engineering projects is very key and important. For the design work, it should not only conform to the basic use function of the engineering project, but also meet the aesthetic needs of the appearance of the building project. In addition, the scientific rationality of the structural design of the engineering project also affects the construction cost of the engineering project, in order to achieve cost saving and the practical requirements of environmental protection and energy saving in the construction industry under the background of the current fierce market competition in the construction industry. In the current stage of construction technology development, the use of space frame structure is very common in the design and construction of many large-span construction projects. Because the space frame structure is used in the construction of engineering projects, it has strong stability and bearing capacity, which also makes the safety and stability of the main structure of the engineering project meet the requirements. In addition, the steel structure also has a certain plasticity, so that the appearance of the engineering project can have more design sense, so that the engineering project has a certain aesthetic connotation, the shape of the building can also be different design according to the need. In the process of engineering project construction, when using space frame structure, we must pay attention to the actual situation of the project, use the best construction equipment and strict construction management to ensure the construction quality and construction safety of the project.

1 Common construction technology of space frame structure in construction engineering

1.1 In the construction of the space frame structure of the construction project, the construction method of the overall lifting is usually adopted. In detail, after the completion of the space frame structure, the lifting connection equipment is installed from the space frame, and then the overall lifting operation of the space frame structure is carried out. The advantages of this construction method are obvious, which can reduce the time of site construction, improve work efficiency and reduce construction cost. However, it should be noted that in the construction of the space frame structure of the engineering project, because it can not be adjusted and modified on site, it is necessary to carry out scientific, reasonable, rigorous and reliable data measurement before the construction of the space frame structure, to ensure that the data of the construction of the space frame structure are fully in line with the needs of the construction of the space frame structure of the engineering project, to ensure the construction quality and construction safety of the engineering project.

1.2 Construction shall be carried out by means of integral jacking

In addition to the common way of the overall lifting construction of the space frame structure, if the support points of the space frame structure of the construction project are relatively few, which cannot meet the overall requirements of the overall lifting construction, then the overall lifting method can be used to carry out the construction of the space frame structure of the construction project. However, the specification standard of lifting equipment required in the process of jacking construction is relatively high, so it is necessary to provide strong lifting capacity. In the operation process of specific jacking construction, the space frame structure of the project should be constructed first, and the relevant accessories on the space frame structure should be installed and set in place, and the equipment in line with the jacking needs of the project should be used for jacking operation. Until the lifting height of the space frame structure meets the height required by the construction of the project.

1.3 Construction shall be carried out by means of integral hoisting

In order to better realize the construction quality of engineering projects and promote the high-level and efficient construction of engineering projects, the lifting construction of space frame structure can also be used for construction. In the preparation process of this construction, it is necessary to carry out the assembly and splicing operation of the space frame structure on the ground, and then strictly check the quality of the space frame structure splicing and assembly, combined with the actual situation of the space frame structure and the construction site of the engineering project, select more targeted, more scientific and reasonable, in line with the construction requirements of the engineering project hoisting mechanical equipment, of course, The application process of hoisting equipment should be based on the premise of full investigation, research and analysis of the construction site of the engineering project. Before the construction starts, it is necessary to ensure the good running state of the mechanical equipment for lifting operation, and lift the prefabricated and spliced space frame structure to the design height of the project. This kind of space frame hoisting construction engineering project construction method is basically applicable to the situation of welding space frame. The assembly and construction of the space frame structure on the ground can ensure the quality and safety of the overall structure of the space frame of the project, and can also better ensure the dimensional accuracy and firm connection of each component of the space frame structure, but the mechanical equipment required in the process of hoisting can provide high hoisting capacity. In addition, it is necessary to use a large number of steel wire rope, auxiliary materials, site management and control personnel and winch, etc. These equipment are essential in the process of site construction of space frame structure hoisting, which leads to a large number of additional costs of engineering project construction. It should also be noted that if the space frame structure of the engineering project will encounter some lifting obstacles after the overall splicing, some components of the space frame structure can be welded after the completion of hoisting construction on the premise of obtaining the consent of the engineering project design unit and the construction management department and ensuring the construction quality and safety of the engineering project.

1.4 Construction shall be carried out by means of suspension assembly

In addition to the above construction operation method of the space frame structure of the engineering project, there is a more flexible and suitable for the construction method of suspension assembly of the engineering project. When adopting the construction technology of the space frame structure of the engineering project, the main components and main structures of the space frame structure of the engineering project should be assembled and spliced in advance in the preparation of the construction work of the engineering project. Then these prefabricated parts will be suspended to the height determined by the design scheme of the engineering project, and then the small units and small components of the space frame structure will be spliced and constructed, and finally a complete space frame structure of the engineering project will be formed in the air. This suspension construction method greatly reduces the requirements of the space frame lifting work of the engineering project for the lifting capacity of mechanical equipment, but it should be noted that the quality and level of the scaffolding construction of the engineering project must meet the requirements and standards of the suspension construction. In addition, the construction personnel of the engineering project need to carry out more aerial work. It is necessary to do a good job in the safety guarantee and safety management of engineering construction, protect the personal safety of engineering project construction personnel, and prevent the occurrence of safety accidents such as falling from high altitude in the construction process.

2 Application of protection device in construction of space frame structure in building engineering

For the construction process of the space frame structure of the construction project, the relevant construction technicians must combine the construction scheme and construction standards of the project, carry out the production of the space frame structure of the construction project at a high level and with high quality, and do a good job in the quality inspection and control of the space frame structure construction. Timely discovery of quality problems and safety hazards existing in the production of space frame structure, to prevent structural deformation and displacement of related components in the process of space frame structure promotion construction, fundamentally ensure the quality and safety of engineering project construction.
