Beijing South Maxpower Technology Co. Ltd's power and non-deformability, the fundamentally rigidity of boist truss.
The utility model to achieve the above object, is achieved through the following technical solutions: including the pipe that winds up, length of tube side of winding up
It is respectively provided with a web member to two sides, two web members are respectively bent to form by a steel bar continuous, and the bending place of web member upper and lower ends is
It is arc-shaped, it is straight-bar, the arc-shaped both ends of each bending place in web member upper end and straight-bar between the arc-shaped bending of web member upper and lower ends
Intersection passes through the first solder joint and the second solder joint and pipe outer wall welding of winding up respectively, and two web member lower end sides are respectively provided with a lower edge
Reinforcing bar, the arc-shaped both ends of each bending place in web member lower end and straight-bar intersection pass through third solder joint and the 4th solder joint and lower edge respectively
Reinforcement welding.Described two lower edge reinforcing bars are located at the outside of two web members.Bottom plate, bottom are set below the web member and lower edge reinforcing bar
Plate is connect with lower edge reinforcing bar.The bottom plate is steel plate, steel plate and lower edge reinforcement welding.The bottom plate is decorative panel.The bottom plate
Upper installation built-in connection, built-in connection are connect with lower edge reinforcing bar.The cross section of the pipe that winds up be hollow ellipse or
Oblong, the web member of top boom two sides are located at the both ends of ellipse or oblong length direction.Filling in the top boom
Hard material.
Utility model has the advantages that the weld of web member upper and lower ends avoids the bending part of web member reinforcing bar, make
Suffered pressure or pulling force are conducted by the straight line portion of web member reinforcing bar between web member upper and lower ends, fundamentally improve truss
Rigidity etc..

Specific embodiment
Steel pipe reinforcing bar composite roof truss described in the utility model includes the pipe 1 that winds up, and 1 length direction two sides of pipe of winding up are respectively provided with
One web member 2, two web members 2 are respectively bent to form by a steel bar continuous, and the bending place of 2 upper and lower ends of web member is arc-shaped, abdomen
It is straight-bar between the arc-shaped bending of 2 upper and lower ends of bar, the arc-shaped both ends of each bending place in web member upper end and straight-bar, which have a common boundary, punishes
Not Tong Guo the first solder joint 3 and the second solder joint 4 and 1 outer wall of pipe welding of winding up, two web members, 2 lower end side is respectively provided with a lower edge reinforcing bar
10, the arc-shaped both ends of each bending place in web member lower end and straight-bar intersection pass through third solder joint 13 and the 4th solder joint 14 under respectively
String reinforcing bar 10 welds.The weld of the utility model web member upper and lower ends avoids the bending part of web member reinforcing bar, makes on web member
Suffered pressure or pulling force are conducted by the straight line portion of web member reinforcing bar between lower both ends, and it is variable to overcome web member segmental arc reinforcing bar
Shape, cannot direct power transmission the shortcomings that, can effectively promote the power conductive performance of web member 2, fundamentally the rigidity of boist truss.
Lower edge reinforcing bar 10 described in the utility model can be welded with the inside of web member, can also be welded with the outside of web member,
Wherein preferred structure are as follows: described two lower edge reinforcing bars 10 are located at the outside of two web members 2.The structure can make two lower edge reinforcing bars
Clamping limit is realized in 10 pairs of web member lower ends, can further promote the resistance to deformation intensity of web member 2.
Truss described in the utility model can also be connected to form truss overlapping board member, structure are as follows: the web member 2 with bottom plate
It is connect with setting bottom plate 11, bottom plate 11 below lower edge reinforcing bar 10 with lower edge reinforcing bar 10.Steel plate, concrete can be used in the bottom plate 11
A plurality of types of plate bodys such as plate and decorative panel can be such that steel plate and lower edge reinforcing bar 10 welds when bottom plate 11 is using steel plate.Work as bottom plate
When the plate body of 11 use concrete slabs, decorative panel or other materials, built-in fitting or connector can be set on plate body, then will be pre-buried
Part or connector connect or weld with lower edge reinforcing bar 10.The process that indoor suspended ceiling can be saved when bottom plate 11 is using decorative panel, has
Conducive to simplified construction step.
Various shapes, such as circle, rectangle etc. can be used in the tube body described in the utility model for winding up pipe 1, wherein preferably
Structure are as follows: the cross section of the pipe 1 that winds up is hollow ellipse or oblong, and the web member 2 of 1 two sides of top boom is located at ellipse
Round or oblong length direction both ends.The structure can effectively subtract in the case where not reducing and winding up 1 load-bearing capacity of pipe
The whole height of few truss promotes interior construction spacing utilization rate, and can increase truss and bottom plate or other building elements it
Between spacing, offer convenience for line layout.
The utility model can fill hard material in the top boom 1 in order to further enhance the rigidity of truss.This is hard
Material can be the multiple materials such as concrete, cement mortar.
