Description
Technical Field
The utility model belongs to the technical field of buildings, and particularly relates to a connecting node of an H-shaped steel beam and a steel frame light roof panel.
Background
With the improvement of the urban modern construction speed and the rapid development of national economic culture level, the current demand of people on houses is greatly increased, the requirement on living quality is increased day by day, the continuous unprecedented development of the house land industry in China is promoted, and the house land industry becomes an important post industry in national economy in China. Meanwhile, the real estate market in China is greatly stimulated by the mass population of rural areas entering the city and the issuance of a series of policies stimulating the residential market, and a favorable environment is created for the development of residential industrialization. In all structural systems, the steel structure is most suitable for industrial production, so that design, production, construction and installation of steel structure houses can be integrated through the systems, the 'field construction' is changed into 'factory manufacturing', and the industrialization and commercialization level of the houses is improved. Meanwhile, the steel structure house has light dead weight and low foundation cost, can be suitable for soft foundations, and has wide application range; the construction and installation are convenient, the construction period is shortened, the construction cost is reduced, the field dry operation can be realized, the environmental pollution is reduced, the materials can be recycled, and the environment protection policy advocated by the state is met.
The steel structure is used in the residential building, so that the construction progress is not influenced by seasons, the building use area is increased, the construction waste and the environmental pollution caused by wet operation of other structure systems are reduced, the steel structure can be recycled, and the development of novel building materials is promoted. Meanwhile, the steel structure system has good anti-seismic performance, the structure arrangement is flexible and convenient, and the steel structure house is easy to reform and brings comfort and the like to people in the use process, so that the steel structure house is deeply loved by the majority of users.
In the action plan of thirteen-five assembly type buildings, the management method of assembly type building demonstration cities and the management method of assembly type building industry bases of the Ministry of residence and construction, it is clearly indicated that the proportion of the assembly type buildings in the whole country is more than 15% of the new buildings by 2020, more than 50 assembly type building demonstration cities are cultivated, more than 200 assembly type building industry bases and more than 500 assembly type building demonstration projects, and more than 30 assembly type building science and technology innovation bases are built. The proportion of the fabricated building is basically required to be more than 30% by 2025. The office hall of the department of building successively announced that 7 provinces such as Shandong, Hunan, etc. develop the assembled house test point, marked that the construction of assembled steel construction is about to enter the rapid development passageway.
Compared with Japan, Europe and America, the development degree of the assembled steel structure in China is lower, and the standardized and efficient structural production standard is lacked, but with the implementation of the assembled steel structure residential building standard, the development of the assembled steel structure in China is further promoted, and the assembly steel structure in China is marked to enter the times of 'standard + mandatory'.
When the assembled steel structure house is constructed and designed, compared with steel beams with other section forms, the H-shaped steel has the advantages of large flange width, large section inertia distance in two directions and good bending resistance, and is suitable for being used as a beam with an assembled steel structure.
The fabricated building nodes generally adopt two connection modes of wet connection and dry connection. The wet connection is that concrete is poured on the beam-column joint firstly, and then the integral structure is poured after the concrete is poured, for example, grout anchor connection, common post-pouring integral connection, common cast-in-place connection, grouting assembly and other connection modes are carried out. The dry connect types are inherently so many, such as a sleeve connection, a pre-stressed crimp, a bracket connection, a welded connection, and a bolted connection. The dry connection has the advantages of convenient construction and the same effect as a cast-in-place structure.
The dry connection research problem is from 1993, a welding connection method is selected firstly, and researches show that the welding node is highly consistent with a cast-in-place node in terms of energy consumption, rigidity and strength. Research of Turkish scientists in 2006 finds that bolt connection is similar to a cast-in-place node in energy consumption, rigidity strength and seismic performance, and construction is more convenient.
The connection joint of the steel beam and the roof panel is one of important stressed parts of the assembled steel structure house, the connection is mostly carried out in a domestic welding form, however, the welding quality is greatly influenced by factors such as steel bar materials, welding rods and weather conditions, the thicker the steel bar diameter, the poorer the connection quality stability, the environmental pollution caused by smoke generated in the welding process, the welding heat can also influence the mechanical property of the steel bar, and the problems of insufficient welding, bubbles, slag inclusion, internal cracks, internal stress and the like are difficult to detect and solve on site. Compared with welding, the mechanical connection joint has stable quality, the steel bar connection quality is guaranteed, the connection strength is high, the connection speed is high, the operation is simple, the influence of human factors is small, the connection quality is not influenced by steel bar materials, the quality inspection is visual and convenient, all-weather construction is realized, energy is saved, fireproof measures are not required to be considered, the site construction is civilized and safe, and the direction of future development in the field of steel bar connection is developed. But the mechanical connection form that assembly type steel structure can adopt in China is less, and most be unsuitable for the connection of steel frame roof boarding, provides a form simply from this, convenient operation's H shaped steel roof beam and steel frame light roof boarding's connected node.
