Description
Technical field
The utility model relates to a kind of floor framing, the superstructure in particularly a kind of steel building.
Background technology
In the construction of construction work, because the design difference of engineering structures, except that the concrete building structures of widespread usage, the application of steel work is more and more, and especially steel work had obtained the development of advancing by leaps and bounds in China in recent years in the public building design.
Traditional concrete structure superstructure has been difficult to adapt to the demand of modern architecture construction because the circulation material input is many, the reinforcing bar materials are big, form of construction work is complicated.At present the profiled sheet that uses of building has advantages such as light unit weight, intensity height, construction be quick, is good constructional materials and member.Profiled sheet can combine with concrete and make composite floor, can save wooden form and can be used as load-carrying members.But problems such as that existing profiled sheet also exists in construction is not good with the concrete structure binding ability, amount of reinforcement big, structural strength and fireproof performance are bad, influence is used.
The utility model content
The utility model provides a kind of closed-section steel deck-concrete combined floor, solve the problem that stress performance is bad, construction material consumption is big of existing profiled sheet and concrete combined floor.
The technical scheme that its technical problem that solves the utility model adopts is: this closed-section steel deck-concrete combined floor, comprise closed-section steel deck and the concrete that is cast on the closed-section steel deck, described closed-section steel deck is layed on the girder steel of steel work main body, fixedly connected with girder steel in the bottom of closed-section steel deck, closed-section steel deck below between the girder steel has been set up and has been shored, be provided with a following iron principal rod in each wave trough of closed-section steel deck, and correspondence is provided with iron principal rod on above every following iron principal rod, socket by lacing wire between following iron principal rod and the last iron principal rod, last iron principal rod is erected on the iron distribution bar, and the two sets up into groined type.
Described closed-section steel deck one side has overhanging button limit, stretches the button limit in opposite side has, and the del that is intervally distributed with the end opening closure between the button limit of both sides is pressed rib.
Described closed-section steel deck is fixing by peg and girder steel welding.
Described shore to set up by horizontal support bar, vertical rod form, and between vertical rod top and closed-section steel deck bottom, be placed with flitch.
The beneficial effects of the utility model are as follows: closed-section steel deck-concrete combined floor of the present utility model, closed-section steel deck directly plays the double floor bottom mould effect of serving as except that as the structure construction material, saves template.In addition, closed-section steel deck fire endurance height, after floor was finished, the sprayed fire proofing coating again in closed-section steel deck bottom played the effect of protection environment, and fireproof performance was good.Simultaneously, the pressure rib of closed-section steel deck plays action of steel bars, therefore, places a following iron principal rod and can satisfy structural requirement in each wave trough of closed-section steel deck, has reduced amount of reinforcement, saves steel, thereby makes this composite floor weight reduction.Because closed-section steel deck is connected on the girder steel by nail solder, peg has played the effect of transmitting the concrete shearing, and span 〉=3m between the girder steel, so only need the closed-section steel deck bottom between girder steel to set up support system, easy construction one.
Closed-section steel deck-concrete combined floor has been broken the floor slab construction mode of traditional concrete structure, embodied and utilized the double construction advantages such as floor bottom mould of doing of closed-section steel deck, it is good to have saved construction material, the weight reduction of floor, floor stress performance.This job practices can shorten the construction period, reduce construction cost, satisfies the structural bearing force request simultaneously, guarantees workmanship, is particularly useful for the high public building structure of fire protection requirement.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of A-A section among Fig. 1.
Fig. 3 is the structural representation of closed-section steel deck.
Reference numeral: 1-girder steel, 2-peg, 3-closed-section steel deck, 3.1-del are pressed and are stretched iron principal rod, the last iron principal rod of 5-, 6-concrete, the last iron distribution bar of 7-, 8-lacing wire, 9-flitch, 10-horizontal support bar, 11-vertical rod under button limit, the 4-in rib, the overhanging button of 3.2-limit, 3.3-wave trough, the 3.4-.
The specific embodiment
Embodiment is referring to Fig. 1, shown in Figure 2, this closed-section steel deck-concrete combined floor, comprise closed-section steel deck 3 and the concrete 6 that is cast on the closed-section steel deck, described closed-section steel deck 3 is layed on the girder steel 1 of steel work main body, fixedlyed connected with girder steel 1 by peg 2 in the bottom of closed-section steel deck 3, closed-section steel deck 3 belows between the girder steel have been set up and have been shored, be provided with a following iron principal rod 4 in each wave trough 3.3 of closed-section steel deck 3, and correspondence is provided with iron principal rod 5 on above every following iron principal rod 4, socket by lacing wire 8 between following iron principal rod 4 and the last iron principal rod 5, last iron principal rod 5 is erected on the iron distribution bar 7, and the two sets up into groined type.
Referring to shown in Figure 3, described closed-section steel deck 3 one sides have overhanging button limit 3.2, stretch button limit 3.4 in opposite side has, and the del that is intervally distributed with the end opening closure between the button limit of both sides is pressed rib 3.1.
The job practices of this closed-section steel deck-concrete combined floor, construction sequence is as follows: step 1, on the girder steel 1 of steel work main body, lay closed-section steel deck 3, setting up to shore below the closed-section steel deck between the girder steel 3 (shores the same with conventional template supporting way, to establish relatively independent horizontal support bar 10 during support, vertical rod 11 and add an amount of bridging, and placing flitch 9 between vertical rod top and the closed-section steel deck bottom on closed-section steel deck before people's operation, to check conscientiously whether support is firm, can hurt sb.'s feelings after infallible and make peg and carry out reinforcement construction).
After step 2, closed-section steel deck are laid and finished, that closed-section steel deck 3 usefulness pegs 2 are fixing with girder steel 1 welding.
The maintenance of sprinkling water after step 7, concrete 6 final set, curing time must not be less than 7 days.
