Furthermore, the pole setting comprises a plurality of branches, all is equipped with one at every vaulting pole subassembly and the corresponding one side of branch and with branch tip matched with sleeve, the sleeve passes through welded fastening in the crossing department of two horizontal poles of vaulting pole subassembly. Like this, the pole setting has the multistage, and the mode of pegging graft through the sleeve between every section and the vaulting pole subassembly is fixed together to can lay the completion back at lower one deck reinforcing bar net piece, fix the last layer vaulting pole subassembly again, form the support to lower one deck reinforcing bar net piece, this kind of mode of setting up, the laying of reinforcing bar net piece of can being convenient for is favorable to accelerating reinforcing bar net piece and lays efficiency.

Furthermore, the section of the sleeve is rectangular or polygonal, and the section shapes of the upper end and the lower end of each supporting rod are consistent with the section shape of the sleeve. Therefore, after the sleeve is rectangular or polygonal, the sleeve cannot rotate under the influence of external force after being spliced with the supporting rod, and the stability is high.

Further, the sleeve is an internal thread sleeve, and the upper end and the lower end of each supporting rod are provided with external threads matched with the threads of the sleeve. Like this, in concrete implementation, can be according to the interval of upper and lower two-layer reinforcing bar net piece, the fastening length of selection sleeve and pole setting, and then adjust the interval of two upper and lower vaulting pole subassemblies, adapt to more operating modes.

Furthermore, a plurality of positioning clamping plates are arranged on the upper end face of each cross rod of each supporting rod assembly at intervals, and a clamping groove used for clamping a water pipe is formed between every two adjacent positioning clamping plates. Like this, the water pipe accessible draw-in groove is fixed, can not break off or appear droing under the concrete extrusion.

Furthermore, the draw-in groove comprises a plurality of limiting plates that set up along the length direction interval of crossbeam, and the interval is unanimous between per two adjacent limiting plates. Like this, the limiting plate setting mode is simple, and the mode that adopts the chucking to set up installs the water pipe comparatively conveniently.

Further, each clamping groove is formed by a U-shaped buckle with an opening at the upper end. Like this, the mode that the water pipe can be gone into from the top down is fixed, and fixed mode is simple, and is convenient.
