Abstract
The utility model relates to a semi-closed pressing assembled floor of steel plate, which is composed of a pressing steel plate, a steel bar grid, and a concrete layer. The upper side of the pressing steel plate is longitudinally and separately provided with inverted triangular bayonet grooves with semi-closed undercuts. The concrete layer is poured on the pressing steel plate, and the steel bar grid, which is composed of longitudinal separation-arranged steel bars and lateral separation-arranged steel bars, is positioned on the upper part of the concrete. The assembled floor has strong structure, light dead load and easy construction, being able to be widely applied to building systems constructed with steel structures.
Description
Technical field
The utility model belongs to construction engineering technical field, is specifically related to use composite floor 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 semi-closure shape of the mouth as one speaks profiled steel sheet combination 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 semi-closed, 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 semi-closure shape of the mouth as one speaks profiled sheet 1 is 0.75-1.5mm, the adjacent spacing of 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 end opening width is less than the upper bottom portion width, be generally 20-70mm, the height of bayonet slot 7 (being the distance of del upper base to the steel floor support plate) is generally 40-80mm, in the steel grid, vertically the adjacent spacing of the reinforcing bar 4 that distributes is generally 100-250mm, and the adjacent spacing of the reinforcing bar 5 of cross direction profiles is generally 100-250mm.
Steel mesh reinforcement compartment distance from upper surface in layer of concrete 2 is generally 15-50mm.
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, vertical distribution reinforcement, 5, transversely distributed steelbar, 6, girder steel, 7, semi-closure shape of the mouth as one speaks 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 commercial affairs building engineering adopts steel frame structural 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 3.5KN/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 2.200m, maximum spacing 4.500m.Floor system adopts the semi-closure shape of the mouth as one speaks profiled steel sheet combination 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 1.0mm, fixing with φ 16 WELDING STUDS 3 with girder steel 6, the middle steel grid of laying is φ 10@120 (the lateral stressed muscle 4 in upper strata), φ 8@180 (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.
