Description
Technical field:
This application involves building material technical field more particularly to a kind of steel bar truss floor support plates.
Background technique:
Currently, the building roof system in well known multi-storey steel structure house, is a kind of preferable using steel bar truss floor support plate
Selection, feature is to use no or little plank sheathing, and live reinforcing bar binding amount is small, and speed of application is fast.But traditional steel bar girder building
Board is deck type, holds diagonal web member tension, load need to be passed on support using two butt head reinforcing bars.Due to processing end steel
Muscle needs manual welding, this requires two workers and welds in the end-to-end head of truss two, guarantees that truss can will be by
Force feedback to steelframe or support on.
Summary of the invention:
Above-mentioned in order to overcome the shortcomings of, the present invention provides a kind of steel bar truss floor support plates.
The technical solution adopted by the present invention to solve the technical problems:
A kind of steel bar truss floor support plate, including steel bar girder and bottom plate, the steel bar girder structure triangular in shape, and along purlin
The setting of frame width direction interval, steel bar girder include the top boom extended along truss length direction, the lower section point of top boom two sides
Two lower booms that She You not extend along truss length direction, lower boom are parallel with top boom；Top boom and two sides and lower boom
It is connected respectively by diagonal web member, diagonal web member is in the wave extended along truss length direction, and the wave crest and top boom of diagonal web member are solid
Fixed connection, trough setting is on bottom plate, and two ends of diagonal web member are equipped with end diagonal web member, after end diagonal web member and lower boom are fixed
Extension is equipped with supporting point, and supporting point is arranged on the bottom plate right above girder steel.
The wave crest is linear structure, and trough is planar structure, and wave crest is parallel with top boom, and trough is parallel with bottom plate.
The diagonal web member is with top boom and lower boom by being welded and fixed.
Due to the adoption of the technical scheme as described above, the present invention has the following advantages:
A kind of steel bar truss floor support plate provided by the utility model eliminates traditional steel using the direct power transmission of end diagonal web member
The end reinforcing bar of muscle truss floor support plate, is directly transferred force on girder steel or support with end diagonal web member, without manually to truss
Both ends carry out welded reinforcement, not only save manpower, and also save the reinforcing bar at both ends, while before guaranteeing stress safety
It puts, alleviates the weight of whole truss.
Detailed description of the invention:
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the cross-sectional view of 1-1 in Fig. 1；
In figure: 1, top boom；2, lower boom；3, bottom plate；4, trough；5, wave crest；6, diagonal web member is held；7, supporting point；8, steel
Beam；9, diagonal web member.
Specific embodiment:
The present invention can be explained in more detail by following example, the open purpose of the present invention is intended to protect model of the present invention
All interior changes and improvements are enclosed, the invention is not limited to the following examples；
A kind of steel bar truss floor support plate in conjunction with described in attached drawing, including steel bar girder and bottom plate 3, the steel bar girder are in three
Angular structure, and be arranged along truss width direction interval, steel bar girder includes the top boom 1 extended along truss length direction, on
1 two sides of chord member are respectively arranged below with two lower booms 2 extended along truss length direction, and lower boom 2 is parallel with top boom 1；
Top boom 1 is connected by diagonal web member 9 respectively with two sides with lower boom 2, and diagonal web member 9 is in the wave extended along truss length direction
The wave crest 5 of line, diagonal web member 9 is fixedly connected with top boom 1, and trough 4 is arranged on bottom plate 3, and two ends of diagonal web member 9 are equipped with end
Extension after diagonal web member 6, end diagonal web member 6 and lower boom 2 are fixed is equipped with supporting point 7, and the setting of supporting point 7 is right above girder steel 8
Bottom plate 3 on.
The wave crest 5 is linear structure, and trough 4 is planar structure, and wave crest 5 is parallel with top boom 1, trough 4 and bottom plate 3
In parallel.
The diagonal web member 9 is with top boom 1 and lower boom 2 by being welded and fixed.
Using the extension of the end diagonal web member 6 and lower boom 2 at 9 both ends of diagonal web member after fixed as supporting point 7, supporting point 7 is
The supporting point 7 is set up directly on the bottom plate 3 of the surface of girder steel 8 by the endpoint of diagonal web member 9, purpose be exactly by truss by
Power be directly delivered on girder steel 8 by diagonal web member 9, without being connected in end welded reinforcement.
9 stability Calculation of diagonal web member is as follows, and by taking 4 meters of span of steel bar truss floor support plate as an example, three truss of every block of plate are calculated,
Diagonal web member diameter 4.5mm, construction stage dead load 3.0KN/m2 , construct live load 1.5KN/m2 , can be in the hope of the end of every truss
Portion's end reaction is 2.28KN, distributes to the axial pressure of every butt diagonal web member 6 and acquires stability series according to slenderness ratio for 1.8KN
Number is 0.621, and may further acquire Stability Checking Calculation stress is 182MPa, less than the intensity 360MPa of diagonal web member reinforcing bar, is met
It is required that.
The utility model uses the direct power transmission of end diagonal web member 6, eliminates the end reinforcing bar of traditional steel bar truss floor support plate.Band
The direct economy effect come is that every production line can use two welders less, is calculated by daily 200 yuan of wage of each welder,
It was calculated by 10 months within 1 year, wage can be saved and pay 120,000 yuan.The fee of material of the end reinforcing bar of traditional steel bar truss floor support plate, folding
Closing to the expense on a plate is about 1 yuan, and a line annual output is calculated by 40 myriametres, and the average length of plate is by 8 meters of calculating, folding
50,000 blocks of plates are closed, and can be cut down expenses 50,000 yuan.Add up to every line every year can be 170,000 yuan with save the cost.Reduce working hour, just
Production efficiency is improved, the yield in the unit time can be improved, more creates value.In addition reduce welding capacity, it can be with
Wlding is saved, the pollution caused by air is just reduced, meets the environmental protection policy of country, there is certain social benefit.
Not stating part in the above content carefully is the prior art, therefore does not run business into particular one and state.
