Abstract
The utility model relates to a prefabricated light steel truss structure, mainly composed of an upper arc tube, a lower arc tube, a web member tube and a connecting auxiliary device. The utility model is characterized in that the web member tube is arranged between the upper arc tube and the lower arc tube of the truss, and a steel joint base is arranged at the connecting position between the upper arc tube, the lower arc tube and the web member tube. A screw hole connected with the web member tube is arranged on the joint base, and both ends of the web member tube are weld with plugging conical points which are provided with central holes. Connecting bolts are arranged in the plugging conical points, and an anti-rotation key and an outer six-square sleeve which can realize the linkage are arranged on the screw bolt. The utility model has the advantages that the prefabricated light steel truss structure can be assembled on field, the construction is easy, and the utility model is suitable for industrial process. The acceptance and the test are simple, and the transportation is convenient. Compared with the prior art, the steel can be saved and the comprehensive benefit is improved.
Description
The utility model relates to a kind of building structure, is meant a kind of assembling light steel truss structure structure especially.
At present, traditional steel roof truss (seeing GB 87SG517), rack and three kinds of main steel structural form of portal frame.Though it is generally adopted in large span industrial premises and communal facilities, above-mentioned three kinds of steel structural form are corresponding to exist following shortcoming: conventional steel roof truss steel using amount is big, and welding procedure can't realize automation, and quality controllable processing procedure degree is low; Though the space truss structure combustion can realize batch production (Automation of Welding) and produce that it is various to assemble aided process at the scene, assembling Quality Control degree-of-difficulty factor height.And portal frame not only requires the post reticular density big, and selects limitation big to supporting roofing materials.
The purpose of this utility model be to overcome the deficiency in the background technology and provide a kind of lightweight, steel using amount is few, and can realize that batch production (Automation of Welding) is produced and the light-duty steel truss of site assembly formula.
The utility model purpose is achieved in that it mainly is made of upper and lower string pipe, web member pipe and connection auxiliary, is characterized in that being provided with the web member pipe between the upper and lower string pipe of truss; Be provided with steel node seat between the upper and lower string pipe and the junction between the web member pipe; Be provided with the screw that is connected with the web member pipe on the node seat, the two ends welding of web member pipe has the shutoff conehead of centre bore; Shutoff is built-in with connecting bolt, and bolt is provided with antirotation keys and realizes the outer six sides cover of interlock.
Wherein, described upper and lower string pipe can be square tube, pipe or special pipe.
The shape of bonding surface also can be made into circle, ball, side or Special-Shaped Surface between the upper and lower string pipe of described node seat and truss.
Described trussed construction can be parallel chords roof truss, triangular roof truss, the shape roof truss of taking out stitches, shaped form roof truss, trapezoid roof truss or prismatic roof truss.
The syndeton of described truss and capital supports for winding up or lower edge supports.
Advantage of the present utility model is: can realize that batch production (Automation of Welding) is produced and the site assembly formula can site assembly, and construction easily, installation rate is fast, and the erection work amount reduces significantly, checks and accepts and detects easily; Convenient transportation; Compared with prior art can reduce the construction steel amount, so improved its comprehensive benefit greatly.
Fig. 1 is the utility model structural representation.
Fig. 2 is pipe and web member pipe tie point structure (amplification of the A portion) generalized section of winding up of the present utility model.
Fig. 3 is a node seat sectional drawing of the present utility model.
Below in conjunction with Figure of description and embodiment, the utility model is further described.
As shown in Figure 1-Figure 3, the utility model mainly by upper and lower string pipe 2,4 with web member pipe 3 and be connected auxiliary and constitute, constitute the truss main body by above-mentioned upper and lower string pipe.Wherein, between the upper and lower string pipe 2,4 of truss, be provided with web member pipe 3; Between upper and lower string pipe 2,4 and the junction between the web member pipe 3 be provided with steel node seat 1; On node seat 1, be provided with the screw 10 that is connected with the web member pipe; The shutoff conehead 6 that centre bore is arranged at the two ends of web member pipe welding tape splicing; In shutoff, be provided with connected nut 5, and on bolt 5, be provided with antirotation keys 8 and outer six sides overlap 7.
Between lower chord tube on node seat 1 and the truss 2,4, can weld in advance or other mechanical fixation; Can realize and being connected of capital with rest 9.
Embodiment:
The first step: the relevant position that node seat 1 is welded in advance upper and lower string pipe;
Second step: with conehead 6 built-in and nut 5 each two two ends that are welded on web member pipe 3 respectively;
The 3rd step: will be outer six sides overlap 7 and antirotation keys 8 be enclosed within respectively on the nut 5 that the centre bore of the two ends conehead 6 of cornical 3 stretches out, and antirotation keys 8 is locked;
The 4th goes on foot: nut 5 is aimed at the reservation screw 10 on the node point seat 1 that is welded on lower chord tube, the six sides cover of turning set outside nut 5 makes the two ends nut fastening, and repeated for the 4th step, makes all web members and last lower edge connect into an integral body; Being equipped with rest 9 can realize and being connected of capital.
In addition, lower chord tube 2,4 and web member pipe 3 can be pipe, square tube or shape tube on the truss; On node seat 1 and the truss between the lower chord tube 2,4 shape of bonding surface also can be made into circle, ball, side or Special-Shaped Surface.
