Specific embodiment
The present invention is the connecting node and installation method of a kind of light steel truss structure, and groove profile gusset plate is equipped at connecting node；
Groove profile gusset plate includes the connecting plate of a pair of side plates and vertical a pair of side plates parallel to the large face；It is each in a pair of side plates pre- to be distributed with
For connecting the pilot hole array of chord member or web member with fastener, pilot hole array is equipped with enough distribution densities, in plane girder section
When being embedded into chord member at any angle and web member between a pair of side plates, the side that chord member and web member face side plate is distributed
There is at least one pilot hole.
Below with reference to examples and drawings, the invention will be further described, but is not limited to the following content.
The connecting node of light steel truss structure provided by the invention, structure are as shown in Figures 1 to 7, comprising: at connecting node
Equipped with the groove profile gusset plate 3 for being connected and fixed chord member 1 and web member 2.
The rod piece of light steel truss structure can be divided into two class of chord member and web member according to its position difference.Chord member refers on truss,
The rod piece of lower periphery, the rod piece of top are known as top boom, and following rod piece is known as lower boom.Between pricncipal rafter and lower boom
Rod piece be known as web member.
The groove profile gusset plate 3, structure is as shown in Fig. 2, include a pair of side plates 6 and same one side in a pair of side plates 6
The connecting plate 7 of edge connection.A pair of side plates 6 is parallel with 3 plate face of groove profile gusset plate, and vertical with connecting plate 7.It is each in a pair of side plates
The pilot hole array for connecting chord member 1 and web member 2 with fastener is distributed in advance, as shown in Figure 1, the pilot hole on pilot hole array is with solid
Fixed spacing distribution, the spacing≤50mm.Make 2 quilt of any angle chord member 1 and web member that plain splice combines in light steel truss structure node
When being embedded between a pair of side plates 6, on the direction perpendicular to side plate, the side phase of side plate is faced with each chord member 1 and web member 2
At least one pilot hole 4 is distributed in corresponding plate region.
The fastener can be the bolt or rivet for being connected as one a pair of side plates, and the diameter and quantity of fastener are determined
The bearing capacity of gusset plate is determined.
Due to having preset pilot hole 4 in side plate in advance, and preset pilot hole 4 and chord member 1 and web member 2 have enough pilot hole weights
It closes, enough strength and stiffness can be provided for connecting node.
The pilot hole 4 is set to ripple close at the trough of chord member 1 or web member 2.Ripple can enhance the intensity of groove profile gusset plate
And rigidity, and the chucking power to chord member 1 or web member 2 can be enhanced.
Pilot hole 4 on the pilot hole array to fix the distribution of modulus spacing, the pilot hole distribution density in pilot hole array is >=
100 every square metre.
Fig. 4, Fig. 5 are the embodiments that ripple is laterally arranged.
The pair of side plate 6, as shown in Fig. 2, its edge is equipped with flange 5 outward.Flange 5 can enhance the rigidity of side plate
And bearing capacity.Due to that groove profile gusset plate 3 can be hindered to be installed in place during plug-in type installs groove profile gusset plate 3, side
Plate 6 is not suitable for inside lateral flange.
The pair of side plate 6 is vertically to be spaced in Fig. 3 as shown in figure 3, being equipped with the ripple of protrusion or recessed lateral plates
Ripple.
Another embodiment is that as shown in Figure 6,7, the side plate 6 is equipped with the pit of recessed lateral plates, and pilot hole 4 is set to
Pit.Side plate may also set up the raised (not shown) for protruding from lateral plates.Pit and protrusion can also enhance groove profile node
The strength and stiffness of plate.
As Figure 1 and Figure 4, the pair of side plate 6 is rectangle, and connecting plate 7 is located at the top of groove profile gusset plate 3, groove profile section
Contact plate 3 is ridden on chord member 1, and web member 2 is set to the side of chord member 1.Directly groove profile gusset plate 3 is ridden set on chord member 1 when installation
On, chord member 1 and web member 2 are embedded into groove profile gusset plate 3, only need directly to fasten in the pilot hole 4 being overlapped with chord member 1 and web member 2
Screw 8 can quickly connect fastening each component of node, thus easy to operate, construction is quickly.If pilot hole 4 is arranged on connecting plate 7,
And chord member 1 is connected by screw 8, then it can further enhance the bearing capacity of node.
The connecting plate 7 connects a pair of side plates and is wholely set with a pair of side plates, a pair of side plates is linked together and is conducive to
The convenience of operation improves construction efficiency, and can guarantee that the holding of the pilot hole in a pair of side plates is oppositely arranged, convenient for fastening snail.
Connecting plate can also directly ride the side for being located at chord member, if pilot hole is arranged on connecting plate, be conducive to be fastenedly connected with chord member
Stability.
Chord member and web member can be fastenedly connected by the step of present invention only needs following sequences to carry out:
Firstly, preparing groove profile gusset plate 3: a pair of parallel side plate 6 being arranged on groove profile gusset plate 3, perpendicular to a pair of side plates
It is fixedly connected or integrally connected connecting plate 7, groove profile gusset plate is made to become U-shaped or H-shaped；Each point of join domain in a pair of side plates
Cloth setting is for the pilot hole array of fastener connection chord member and web member, the density of pilot hole array distribution to make any angle flat enough
When the face chord member 1 spliced and combined and web member 2 are embedded between a pair of side plates 6, on the direction perpendicular to side plate, with each string
The plate region that bar 1 and web member 2 are overlapped is distributed at least one pilot hole, the distance between a pair of side plates 6 just embeddable chord member
1 and web member 2；In general, the plate region point that the distribution density of settable pilot hole array is overlapped each chord member 1 and web member 2
It is furnished with 2~4 pilot holes.
Then, it is embedded in groove profile gusset plate 3: the connecting plate of groove profile gusset plate 3 is parallel with chord member 1, and be open towards chord member
1, groove profile gusset plate 3 is ridden set on 1 side of chord member and against chord member 1；
Finally, being fastenedly connected with screw: chord member 1 and web member 2 and side plate 6 side overlapping position pilot hole from the outer of side plate
Side penetrates screw, and side plate 6 is fastened with each chord member being overlapped 1 and web member 2.
The connecting plate of connecting node is standardized prefabricated by the present invention, and a pair of side plates, which is linked together, easily facilitates operation,
As long as the distribution density of pilot hole is enough, that is, can guarantee side plate on can have sufficient amount of pilot hole for directly with web member and chord member
Connection, eliminate being pre-designed for gusset plate, standardization level and high production efficiency, speed of application is fast, to construction personnel's skill
Art requires low.
