Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
Fig. 1 is a schematic structural diagram of the present invention, fig. 2 is a schematic structural diagram of a first connection frame of the present invention, and fig. 3 is a schematic structural diagram of a second connection frame of the present invention.
A combined splayed strut member in a prestressed truss profile steel support comprises a connecting piece, an inclined strut rod 1 and a straight strut rod 2, wherein the connecting piece consists of triangular blocks 3, a first connecting frame 4 and a second connecting frame 5, more than one first connecting frame 4 and more than one second connecting frame 5 are fixed to form a combined frame, the length of the first connecting frame 4 is greater than that of the second connecting frame 5, and more than one triangular blocks 3 are fixed on one side of the combined frame; the connecting piece top vertical fixation has several straight vaulting poles 2, and the connecting piece bottom vertical fixation has several straight vaulting poles 2, is fixed with an inclined support rod 1 on each triangle piece 3, passes through horizontal pole fixed connection between the connecting piece of two mutual symmetries. The first connecting frame 4 and the second connecting frame 5 are composed of a contour plate and a web plate, the contour plate is a rectangular plate body, and the web plates parallel to each other are fixed in the contour plate. A plurality of bolt holes are uniformly distributed in the contour plate. And a plurality of bolt holes are distributed on the plane of the triangular block 3.
As shown in fig. 1, 2 and 3, two mutually symmetrical connecting pieces are fixed together by a cross bar, and the triangular blocks 3 are positioned at the outer side of the combined frame. A plurality of inclined supporting rods 1 which are vertically fixed on the plane of the triangular block 3 are respectively positioned at two sides of the whole splayed supporting piece, thereby forming a splayed supporting mechanism. The end of the inclined support rod 1 and the end of the support rod 2 are fixed on the surrounding purlin of the foundation pit. The structural strength of the whole supporting mechanism is enhanced by using the splayed supporting structure.
The number of the first connecting frame 4 and the second connecting frame 5 can be adjusted according to the requirement by the connecting piece, so that the number of the triangular blocks 3 can be adjusted according to the requirement. The length of the first connecting frame 4 is different from that of the second connecting frame 5, so that the length of the connecting piece can be adjusted.
