The adopted technical scheme is as follows: the steel girder component comprises an upper panel, a lower panel and an intermediate framework structure, wherein square openings are formed in the middle of a guide rail of the intermediate framework, end sockets are arranged at the two ends of a pectoral plate of a cross beam, the end sockets extend into the two square openings formed in the middle of the guide rail, the rest part of the pectoral plate is bent and then fixedly connected with the guide rail through a bolt, a hole which is convenient for a line tube to penetrate through is formed in the middle of the pectoral plate, an upper wing plate of the cross beam is connected with the pectoral plate through an upper reinforcing plate, and a lower wing plate is connected with the pectoral plate through a lower reinforcing plate. The steel girder component in the structure is reduced in the integral weight, and improved in the integral bearing capacity, an independently arranged threading layer is saved, and the thickness of the floor slab is reduced.
Description
Technical field
The utility model relates to the building hardware, is specifically related to steel building floor assembly.
Background technology
Series of advantages such as that steel building has is good from heavy and light, antidetonation, thermal and insulating performance, dry construction, the duration is short, cost is low, what adopt steel building abroad at present mostly is iron and steel big producing country and the relatively advanced countries and regions of steel building.Light steel building structure is very fast in America and Europe's development, in the U.S., Canada, Australia, Japan, countries such as Sweden, steel using amount in the steel work has accounted for more than 30% of steel output, steel building is occupied more than 40% of residence overall floorage, the individual layer and the tier building that adopt the steel structure system construction to build account for more than 50%, the newly-built 4 layers of dwelling house of 1-of Japan mostly adopt steel work, the dwelling house in Israel resident settlement also is based on steel building, and these countries are in the anti-seismic performance of steel building, fire prevention, antiseepage, constructional materials, the research of aspects such as form of structure is in world lead level.The U.S. is very perfect on analysis, design-calculated theory and method and the manufacturing process of steel structure system, developed multiple product, its special-purpose design software can be finished design, drawing, engineering quantity statistics and project quoted price at short notice, has also realized standardization and the batch production of height on making.Sweden is steel work manufacturing nation maximum in the world today, and prefabricated units quantity reaches 95% in its steel building.At present on the steel building system, developed steel work suitability for industrialized production system abroad, and constantly promote the performance indications of dwelling house product, and external research entered to dwelling house system flexibility, Study on Diversity, and then enlarge adaptive surface and produce scale effect.The Chinese architecture rolling shapes are abundant, reasonable price, new product development is many, hot rolling H shaped steel, cut deal, shaped steel, steel pipe, high-frequency welding H shaped steel, cold-rolled forming section and coated layer steel plate etc. have phenomenal growth, the steel of all size are provided for steel building, in addition for promoting China's steel building industry development, the Ministry of Construction is in having issued " steel building industrialization technology guide rule ", and the steel of construction steel structure, design, manufacturing, construction, industry standard, standard are worked out revision substantially and finished.To the engineering pilot, development speed is very fast from research and development for domestic steel building.
In steel house, floor must have enough bearing capacities, rigidity and globality, and therefore, it is except directly distributing to vertical load the wall column, and more significant feature is the reconciling spatial scale effect of assurance and lateral resisting structure; From the antidetonation angle, also should adopt corresponding technology and construction measure to alleviate the floor deadweight.Building cover structure commonly used has: 1. profiled sheet-cast-in-situ concrete composite floor, namely lay profiled sheet at girder steel, build armored concrete slab again, be connected with peg between profiled sheet and the girder steel, this structure is thicker than conventional concrete floor, and weight is also bigger, require higher for the strength of wall body that supports floor, and overall structure and technology is more complicated all, and construction costs is higher, is not suitable for most steel building and uses; 2. adopt U-shaped or C type channel-section steel as left and right rail, the centre arranges crossbeam, lay panel by the mode of riveted joint or welding up and down then, and the reservation pipeline layer, the weight capacity U-shaped or C type channel-section steel that adopts on this structure is not high, can't be used for the steel building of multilayer, and because the centre of plate is sealed, pipeline layer need be set separately, and this has just increased the thickness of plate, has also increased cost of production.
Summary of the invention:
Be to solve the problem that exists in the background technology, the purpose of this utility model is to provide a kind of simple in structure, overall weight is light, weight capacity is high steel building floor girder steel assembly.
For achieving the above object, the utility model has adopted following technological means: a kind of steel building floor girder steel assembly, constituted by upper and lower panel and central frame, it is characterized in that, central frame comprises the U-shaped guide rail 1 in left side, the U-shaped guide rail 2 in right side and crossbeam 3, end position is provided with square aperture 4 in the U-shaped guide rail 2 of the U-shaped guide rail 1 in described left side and right side, web 5 two ends of described crossbeam 3 are provided with the termination 6 that width is the 3/5-2/3 of web 5, web 5 middle parts are provided with the hole 7 of being convenient to penetration pipe, the upper flange 8 of crossbeam 3 is connected by upper reinforcing plate 9 with web 5, lower wing plate 10 webs 5 connect by lower reinforcing plate 11, termination 6 is stretched in two square aperture 4 that end position is offered in the U-shaped guide rail 1 in left side and the U-shaped guide rail 2 in right side, and unnecessary part is fixedlyed connected with the U-shaped guide rail 2 in right side by the U-shaped guide rail 1 in bolt and left side after bending.
The pipeline kind that the hole 7 that described web 5 middle parts arrange can wear as required is set to circle, triangle, square etc.
The beneficial effects of the utility model are:
1. the square aperture offered of left and right side guide rail penetrates the termination on the supporting web, and the weight that can disperse crossbeam to bear after connecting by bolt improves whole weight capacity;
2. be provided with the hole of being convenient to penetration pipe on the web, use for reality to have increased facility, and alleviated overall weight;
3. reduce the threading layer of independent setting, reduced the thickness of floor, simultaneously between web and wing plate, set up stiffener, offset the intensity that perforate causes and weakened, improved weight capacity greatly.
