Abstract
The utility model relates to a closed pressing steel plate combined floor board, which is composed of a steel building bearing board, a steel bar grid and a concrete layer. Inversed triangular bayonet grooves with closed undercuts are longitudinally arranged on the upper side of the steel building bearing board with certain intervals. The concrete layer is poured on the steel building bearing board, and the steel bar grid, which is composed of longitudinally arranged steel bars with certain intervals and laterally arranged steel bars with certain intervals, is positioned on the upper layer of the concrete. The combined building bearing board has strong structure, light weight and easy construction, being able to be applied to building systems constructed with steel structures.
Description
Technical field
The utility model belongs to construction engineering technical field, is specifically related to the composite floor that uses in a kind of steel building.
Background technology
Along with a large amount of rises of steel building in China, the attention that many high-rise steel structure are built with its intensity height, from heavy and light, serial advantages such as anti-seismic performance is good, speed of application is fast, ground cost saving, area occupied is little, industrialization degree is high, good looking appearance, environmental protection more and more are subjected to various places government, large-scale steel structure company and real estate developer.And in the construction work of many high-rise steel structure, the selection of floor system is an important link, and superior floor system should possess intensity height,, short construction period good from heavy and light, anti-seismic performance, industrialization degree is high and characteristics such as good fire prevention, anticorrosion, barrier performance are arranged.In engineering in the past, floor pattern commonly used has cast-in-place concrete floor, prestressed concrete overlapped slab, two-way multi-ribbed plate, and these floor systems exist following shortcoming:
1, cast-in-place concrete floor: floor need carry out formwork, form removal from great, the construction trouble, and also formwork seal is poor, easily produces the spillage phenomenon, long construction period.
2, prestressed concrete overlapped slab: owing to adopt is partly prefabricated partly cast-in-place, and it is convenient inadequately to transport, stack, site operation layout underaction, and position in-situ processings such as bearing, plate lap-joint are cumbersome.
3, two-way multi-ribbed plate: template is had relatively high expectations, the construction trouble, stressed complexity easily produces weak part.
Based on above situation, the applicant absorbs the achievement that scientific research both at home and abroad, design, construction in recent years provide a reference in conjunction with engineering practice, has developed the closed-section steel deck composite floor.
Summary of the invention
The composite floor that the purpose of this utility model is to propose a kind of intensity height, uses from the steel building of heavy and light, easy construction.
The composite floor of the utility model design is made of profiled sheet, steel grid concrete, and its structure as shown in Figure 1.Wherein, profiled sheet 1 is positioned at the bottom, its upside vertically and be intervally distributed with the del bayonet slot 7 of end opening closure, layer of concrete 2 is built on profiled sheet, steel grid is made up of longitudinal separation reinforcing bar 4 that distributes and the reinforcing bar 5 that the lateral separation distributes, and is positioned at the top section of layer of concrete 2.
The composite floor of the utility model design, its thickness is generally 90-250mm, and its width determines that according to concrete template be generally 400-800mm, length is generally 1000-12000mm.Wherein, the thickness of closed-section steel deck 1 is 0.75-1.5mm, spacing between the del bayonet slot 7 that its upside vertically distributes generally can be 80-250mm, the upper bottom portion width of bayonet slot is 30-80mm, the height (be under the del drift angle to the distance of steel floor support plate) of remaining silent is generally in the 40-80 steel grid, vertically the spacing between the reinforcing bar 4 that distributes is generally 100-250mm, and the spacing between the reinforcing bar 5 of cross direction profiles is generally 100-250mm, and these bar diameters are 6-14mm.The steel mesh reinforcement compartment is generally 15-50mm from the upper surface distance in layer of concrete 2.
The composite floor of the utility model design, structural strength is big, and it is little to conduct oneself with dignity, easy construction.
Description of drawings
Fig. 1 is the structural profile diagram of this composite floor.
Fig. 2 is this composite floor medium-pressure type steel plate and the diagram that is connected of girder steel.
Number in the figure: 1, profiled sheet 2, layer of concrete, 3, WELDING STUDS, 4, transversely distributed steelbar, 5, vertical distribution reinforcement, 6, girder steel, 7, the closo bayonet slot.
The specific embodiment
The closed-section steel deck composite floor of the utility model design mainly is applicable to the floor system of many high-rise steel structure buildings.This profiled sheet combines with girder steel can adopt WELDING STUDS, sees shown in Figure 2.
Concrete construction sequence of the present utility model is as follows: the first step: the steel beam surface that desire is placed profiled sheet is removed clean, setting-out and finish mark.Second step: carry out the laying and the necessary perforate and the shutoff of profiled sheet.The 3rd step: treat with WELDING STUDS profiled sheet to be fixed on the girder steel after profiled sheet laying adjustment finishes.The 4th step: the laying and the necessary embedded part that carry out top reinforcement.The 5th step: concrete building and maintenance.
Certain steel work office building engineering adopts steel frame supporting structure system, and architectural design service life is 50 years, and safety classes of structure is a secondary, and building aseismicity is set up defences and is categorized as Class C, and seismic fortification intensity is 8 degree, flooring live load 2.0KN/m
2, the above agent structure in ground is a steel work, framework primary and secondary beam all adopts H type cross section, secondary beam minimum spacing 2.000m, maximum spacing 4.000m.Floor system adopts the closed-section steel deck composite floor of the utility model design, relevant design parameters is as follows: the composite floor gross thickness is 110mm, the bottom is a closed-section steel deck 1, adopt the thick G300 shaped steel plate of 0.9mm, fixing with φ 16 WELDING STUDS 3 with girder steel 6, the middle steel grid of laying is φ 10@150 (the lateral stressed muscle 4 in upper strata), φ 8@200 (the vertical distribution bar 5 in upper strata) two-way concrete slab net, and C30 layer of concrete 2 is built on top.
This composite floor can satisfy the needs of engineering design.
