Abstract
The utility model discloses the splicing nodes of a kind of assembled steel tubular truss lower edge crossbeam and lower edge chord member, it is used to splice the high-strength bolt (3-2) of lower edge crossbeam (2) in the cage plate end (3-1) including the cage plate (3-1) being welded on lower edge chord member (1) for connecting lower edge crossbeam (2), and setting.The splicing node of a kind of assembled steel tubular truss lower edge crossbeam and lower edge chord member provided by the utility model has the characteristics that stability is good, convenient disassembly, is not required to on-the-spot welding.
Description
Technical field
The utility model relates to the splicing nodes of a kind of assembled steel tubular truss lower edge crossbeam and lower edge chord member.
Background technique
In assembled steel tube Truss Design, lower edge chord member uses steel tube component, and lower edge crossbeam uses H profile steel component,
Connection between the two cannot be connected using the intersecting welding of steel pipe truss structures, it is therefore desirable to which it is good to design a kind of stability, easily
In the splicing node of construction, economical rationality.
With site operation (mainly on-the-spot welding) cost increase and transport capacity enhancing, assembling truss, bracket must
So become trend.Wherein assembling truss, bracket splicing node need to have stability good, be easy to the characteristics of constructing.Wherein lead
Wanting the splicing such as splicing design of node of lower edge crossbeam and lower edge chord member between primary structure member is in the weight of assembled steel tubular truss
Weight.
Utility model content
The purpose of this utility model is to provide the splicing sections of a kind of assembled steel tubular truss lower edge crossbeam and lower edge chord member
Point, for solve the problems, such as assembling truss scene splicing be easier to construction, splicing node stability it is more preferable.
In order to achieve the above objectives, the utility model adopts the following technical solution to realize:
A kind of splicing node of assembled steel tubular truss lower edge crossbeam and lower edge chord member, including for connecting the weldering of lower edge crossbeam
The cage plate being connected on lower edge chord member, and cage plate end is set for splicing the high-strength bolt of lower edge crossbeam.
The utility model, which further improves, to be, further includes the ribbed stiffener for reinforcing cage plate lateral stability.
The utility model, which further improves, to be, lower edge chord member is made of steel tube component.
The utility model, which further improves, to be, lower edge crossbeam uses lower edge H-type crossbeam.
Compared with prior art, the utility model has the advantage that
The utility model is inserted in lower edge chord member using cage plate, along lower boom section and cage plate junction at lower edge chord member node
One whole circle welding, strengthens fusion length, enhances weld seam bearing capacity.
Further, cage plate end is spliced with lower edge crossbeam (H profile steel girder steel) web high-strength bolt, so that splicing node
Site operation is convenient, reduces difficulty of construction.
Further, lower edge crossbeam uses H profile steel component, reduces project cost.
Further, the ribbed stiffener added on cage plate makes the stability of node at this more preferable, can preferably be suitable for
Assembled steel tubular truss lower edge crossbeam splicing under various angles.
Detailed description of the invention
Fig. 1 is that a kind of assembled steel tubular truss lower edge crossbeam of the utility model and the structure of the splicing node of lower edge chord member are shown
It is intended to.
In figure: 1 is lower edge chord member, and 2 be lower edge crossbeam, and 3-1 is cage plate, and 3-2 is high-strength bolt, and 3-3 is ribbed stiffener.
Specific embodiment
Further detailed description is done to the utility model with specific implementation measure with reference to the accompanying drawing.
As described in Figure 1, the splicing of a kind of assembled steel tubular truss lower edge crossbeam and lower edge chord member provided by the utility model
Node, including the cage plate 3-1 for being connected to lower edge chord member 1 for splicing lower edge crossbeam 2, for reinforcing cage plate 3-1 lateral stability
Ribbed stiffener 3-3, and the end cage plate 3-1 is set for splicing the high-strength bolt 3-2 of lower edge crossbeam 2.Wherein, lower edge chord member 1
And lower edge crossbeam 2 is determined according to practical engineering calculation.Wherein, the size of ribbed stiffener 3-3, arrangement are according to Practical Project actual conditions
It is configured, by the way that ribbed stiffener 3-3 is arranged, reinforces the cage plate 3-1 lateral stability of angled truss, added on cage plate 3-1
Ribbed stiffener 3-3 makes the stability of node at this more preferable, the assembled steel tubular truss that can be preferably suitable under various angles
The splicing of lower edge crossbeam.Wherein, high-strength bolt 3-2 uses frictional high-strength bolts, and model is according to Practical Project lower edge crossbeam 2
Stress determines.Wherein, the thickness of cage plate 3-1 is calculated according to Practical Project interior joint stress condition and is determined.Lower edge chord member 1 uses steel
Pipe component is made, and lower edge crossbeam 2 uses lower edge H-type crossbeam.
Splicing node of the utility model between assembled steel tubular truss lower edge crossbeam 2 and lower edge chord member 1 uses cage plate
Formula splices node, which is welded at 1 node of lower edge chord member using cage plate 3-1, and several transverse stiffener 3- is arranged
3, to enhance cage plate 3-1 stability；High-strength bolt 3-2 is arranged in the end cage plate 3-1, is attached with the web of lower edge crossbeam 2, with
Achieve the purpose that be easy to construction, economical rationality.
Although the preferred implementation of the utility model is described above in conjunction with attached drawing, the utility model not office
It is limited to above-mentioned specific implementation method, above-mentioned specific implementation method is only schematical, rather than restrictive, this field
Conventional design personnel under the enlightenment of the utility model, do not departing from the utility model aims and claimed model
In the case of enclosing, many forms can also be made.
