Description

Technical Field

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

[0002] With the development of the construction industry and the improvement of land utilization rate, people are making more and more use of building space. At present, the area between adjacent buildings usually adopts closing measures to form a closed space with a large floor height for public activity areas. With the development of the construction industry, the utilization rate of mid-bearing steel box beam roof trusses is getting higher and higher. 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. A regular polygonal grid design is usually adopted. In the specific construction process of the mid-bearing steel box beam roof truss, there are the following problems: 1) The mid-bearing steel box beam roof truss is connected to the building structure through sliding supports. During the use of the building, structural deformation and thermal expansion and contraction of the steel structure roof truss are inevitable, so it is difficult to close the roof. It is necessary to ensure the expansion and contraction of the roof truss and to ensure that the roof truss is tightly closed to prevent rainwater from flowing into the room and fire caused by loose closure to produce chimney effect. 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, stainless steel drainage grooves will be laid on the steel box beam truss. At present, the stainless steel drainage grooves are directly installed on the truss, which is easy to resonate and transmit the drainage sound into the room. 3) The lighting of the steel box beam truss will encounter the problem of laying cables and wires. In order to achieve the overall effect of the truss, the lamps and wires and cables should be laid in a concealed manner and integrated with the steel box beam. Since the steel box beam is a load-bearing component, there are a large number of stiffening plates at the beam nodes. If a hole is opened at the bottom of the beam and the stiffening plate is opened, the line will pass through the inside of the beam, causing a weak point in the local structure. The convection between the air inside the beam and the indoor air will accelerate the corrosion of the internal structure of the beam, which will inevitably affect the safety of the structure; if the open line is used in the wire tube, the wire tube on the top of the roof truss will be messy, affecting the aesthetic effect of the top of the roof truss. 4) The roof covering of the steel structure box beam roof truss usually adopts the thermal insulation integrated board. However, during its construction process, the installation point of the thermal insulation integrated board cannot be accurately positioned on the keel. The bending of the corrugated steel plate of the thermal insulation integrated board will flatten the wave crest. The corrugated steel plate of the thermal insulation integrated board is inclined by bending, which affects the appearance. Summary of the invention

[0022] The steel structure box beam roof system of the present invention has been redesigned relative to the existing traditional roof, including various aspects such as structural design and connection design, which completely solves the various problems mentioned in the background technology of the traditional roof. The existing traditional roof relies on the sliding support at the bottom of the roof truss to solve the deformation problem of the roof truss, and adopts the method of each layer of the roof tightly fitting with the building structure and sealing the joints with glue. The present invention does not completely rely on the sliding support. The roof adopts a multi-layer composite roof, and each layer of the roof is provided with a corresponding compensation device at the connection with the building structure, which ensures the telescopic function of the roof truss and meets the requirements of the structural deformation and thermal expansion and contraction on the telescopic performance of the roof truss; 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 fires from occurring due to poor closure to produce a chimney effect; the roof closure of the present invention is ingenious, which simplifies the construction process, shortens the construction period, and reduces the construction cost. 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 arranging the drainage trough, so that the drainage trough is separated from the box beam and does not directly contact the box beam, and the 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. The existing traditional roof adopts external downlights and line piping installation, which can meet the functional requirements, but is incompatible with the overall effect of the ceiling. After adopting the present invention, all lines and lighting fixtures are concealed, and the pipe corridor adopts the same width and color as the steel structure box beam, which is perfectly integrated with the ceiling. In the present invention, the joints between the horizontal surface thermal insulation integrated board and the vertical surface thermal insulation integrated board are specially treated to ensure that the wave crests are horizontal and vertical on any surface, and the positive and negative corners are tightly sealed, resulting in a beautiful roof construction effect.

[0023] In summary, the steel structure box beam roof system of the present invention has a scientific design, a reasonable structure, and high precision, which improves the construction quality, increases the construction efficiency, greatly reduces the construction cost, and has a beautiful construction effect, and has great application and promotion value.
