The supporting truss end is provided with the groove connecting piece, and the steel beam web is connected with the truss support through bolts.

The truss support is welded with the nut to be connected with the bolt, and the upper part of the bolt is embedded into the groove connecting piece to jack up the supporting truss.

The inverted tripod is formed by welding a rectangular pipe.

The rectangular tube at the middle section of the upper chord penetrates into the rectangular tube at the upper chord of the inverted triangular frame and is fixed through the bolt.

The supporting truss is characterized in that a tightener is arranged on the lower chord of the supporting truss, and a lifting hook of the tightener is connected with an intersection point of the inverted tripod web members.

And a connecting hole is drilled at each section of the rectangular pipe at the middle section of the upper chord, and the adjustable distance between the tops of the bolts at two sides in the groove connecting piece is greater than the drilling distance of the rectangular pipe at the middle section of the upper chord.

The utility model discloses owing to adopted above-mentioned technical scheme, following beneficial effect has:

1. the utility model discloses connecting hole is designed to one section distance of last quarter interlude quarter pipe every, makes last quarter interlude quarter pipe and falling tripod go up this section distance of quarter and can pass through the latch connection. The tops of the bolts at the two sides can move in the groove connecting piece, and the moving range is larger than the distance of the rectangular tube connecting holes at the middle section of the upper chord, so that the supporting truss can be adjusted in any length within a certain range. The supporting truss is suitable for various plate crossing conditions, the reuse rate is higher, and the single-use cost is reduced.

2. The utility model discloses truss support welded nut connecting bolt, the embedding of bolt upper portion groove connection spare jack-up braced truss. The height can be adjusted within a certain range, so that the floor slab is convenient to level, the construction quality is higher, and the truss is convenient to disassemble.

3. The utility model discloses the inverted triangle frame comprises the quarter bend welding and penetrates the design of the quarter bend pipe on the inverted triangle frame with last quarter interlude quarter bend, makes construction speed faster, and structural strength is higher.

4. The utility model discloses the braced truss last quarter sets up the turn-buckle, and the turn-buckle lifting hook is nodical with the falling tripod web member and is connected. The supporting truss arching is realized through the tightener, so that the supporting truss is kept free of downwarping after concrete pouring, and the adjustment is more convenient.
