Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and particularly relates to the construction of a steel structure box beam metal roof, in particular to a steel structure box beam metal roof enclosing system. Background Art

[0002] With the development of the construction industry and the improvement of land utilization rate, people have more and more demands for large-space buildings. In order to meet the needs of the masses, steel box-beam roof trusses are used more and more frequently in large-space buildings. Now, in order to reflect the assembly effect, the steel box-beam roof trusses are divided into smaller and smaller parts, and the degree of standardization is getting higher and higher. Regular polygons are usually used for splicing to form a regular polygon grid-shaped box-beam steel structure roof. Steel box-beam roof trusses need to have the effects of thermal insulation, sound insulation and noise reduction, and smooth drainage. However, during the construction of steel box-beam roof trusses, there are the following problems: 1) The steel box-beam roof trusses are connected to the building structure through sliding supports. During the use of the building, structural deformation and thermal expansion and contraction of the steel roof trusses are inevitable, so it is difficult to close the roof. It is necessary to ensure the expansion and contraction of the roof trusses and to ensure that the roof trusses are tightly closed to prevent rainwater from flowing into the room and fires caused by loose closures to produce chimney effects. Therefore, this type of building has many nodes during construction, and there are problems such as greater difficulty in closing, long construction period, and high construction cost. 2) In order to ensure the waterproof and drainage effect of the roof, drainage grooves will be arranged on the steel structure box beam roof truss. At present, the drainage grooves are directly installed on the roof truss, which is easy to resonate and transmit the drainage sound into the room. 3) The roof of the steel structure box beam roof truss is usually enclosed with an insulation integrated board, but during its construction, the installation point of the insulation integrated board cannot be accurately located on the keel. The bending of the corrugated steel plate of the insulation integrated board will flatten the wave crest. The corrugated steel plate of the insulation integrated board is tilted when it is bent, which affects the appearance. Summary of the invention

The roof layers are closely fitted with the building structure and the joints are sealed with glue. The present invention does not completely rely on the sliding support. The roof adopts a multi-layer roof structure, and each layer of the roof is provided with a corresponding compensation device at the connection with the building structure, which ensures the expansion and contraction function of the roof truss and meets the requirements of the expansion and contraction performance of the roof truss due to structural deformation and thermal expansion and contraction. At the same time, the closure of the roof truss is also extremely tight, which can prevent rainwater from flowing into the room and prevent fire from occurring due to poor closure to produce a chimney effect. The existing traditional roof has the drainage trough directly placed on the roof frame. When it rains, the drainage sound is loud and easily resonates with the roof frame, resulting in high indoor noise. The roof system of the present invention is designed with a support frame, wherein the two first horizontal cross bars of the support fixing part and the two vertical water pressure resistant columns and a horizontal beam of the multiple groups of support force parts form a special placement groove for placing the drainage trough, so that the drainage trough is separated from the box beam and does not directly contact the box beam, and sound-absorbing rock wool is filled between the support fixing part and the box beam, which effectively eliminates the noise. At the same time, the gap between the drainage trough and the box beam also provides construction space for the installation of the drainage pipe. In the present invention, the joints of the horizontal surface thermal insulation integrated board and the vertical surface thermal insulation integrated board are specially treated to ensure that the wave peaks are horizontal and vertical on any surface, and the positive and negative corners are tightly closed, and the roof construction effect is beautiful.

[0016] The invention has scientific design, reasonable structure, high precision, improves construction quality, increases construction efficiency, greatly reduces construction costs, has beautiful construction effects, and has great application and promotion value.
