Specific embodiment
With reference to the accompanying drawings and examples this utility model is further illustrated.
One kind as shown in Figure 2 no pull bar H profile steel truss U-type groove side template strengthening system, this reinforcement system includes vertically
Master is stupefied, the stupefied and side wall template of level time, also includes truss and lacing wire.
Described vertically lead the stupefied H profile steel using the setting of multiple constant spacings, described H profile steel be L9m × 244mm ×
Edge of a wing H profile steel 20 in 175mm hot rolling, in hot rolling, the spacing between edge of a wing H profile steel 20 is 800mm.Edge of a wing H profile steel 20 in this hot rolling
The upper and lower side first and second pre-buried key 50,60 that respectively Guan Liang 80 and side wall 90 bracket is embedded in by correspondence fixing, so that hot rolling
Middle edge of a wing H profile steel 20 is fixing perpendicular to base plate 100.So, in hot rolling, edge of a wing H profile steel master is stupefied is the formation of upper and lower two to four phases
The fulcrum of counteracting force, to overcome concrete lateral pressure to deform arch camber to the effect of side template 70, reduces the several of the swollen mould of U-type groove side template
Rate and risk.
Incorporated by reference to the pre-buried key of shown in Fig. 3-5, be embedded in Guan Liang 80 first 50 be embedded at side wall 90 bracket second
Pre-buried key 60 is made up of two relative L-type lacing wires in long side.As shown in figure 4, the two ends on long side 52,62 that L-type lacing wire exposes
Head thread, forms the exposed threads screw thread 53,63 of long 8cm, and concrete 0.75m imbedded by reinforcing bar, exposes 0.65m.The minor face of L-type lacing wire
51st, 61 embedment concrete.As shown in figure 3, after in described hot rolling, edge of a wing H profile steel 20 is placed between two L-type lacing wires, reusing as figure
Two through holes 201,202 that the thick punched steel plate 200 of 20mm shown in 5 passes through which is provided with are enclosed within two L-type lacing wires, and lead to
Cross M24 high-strength nut and adjust fixation with screw thread 53,63.
The truss 30 of this utility model U-type groove side template strengthening system is arranged on the middle part of edge of a wing H profile steel 20 in hot rolling, institute
The truss 30 stated is fabricated to the horizontal support of truss 30 using L75 × 75 × 5mm angle steel.The interior long side of truss 30 and hot rolling wing centre section
Edge H profile steel 20 is welded and fixed.
The lacing wire of this utility model U-type groove side template strengthening system is upper and lower oblique lacing wire 40, described oblique lacing wire by
L30 × 30 × 3mm angle steel makes.The two ends of upper and lower oblique lacing wire 40 are corresponding respectively to be passed through flange or is weldingly fixed on truss 30
Upper and lower outer corner and hot rolling in edge of a wing H profile steel 20 upper and lower end.Described upper and lower oblique lacing wire 40 constitutes one with truss 30
The larger truss support component of individual rigidity, has reached underpass U-type groove side wall tall and big side wall template entire body and has been not provided with spiral shell through walls
The requirement of bar construction is it is ensured that the waterproof system of underpass main body is unaffected.
Level time stupefied 10 in this utility model U-type groove side template strengthening system adopts flitch and the side of 100mm × 100mm
Wall form 70 is fixedly connected by steel nail, and secondary stupefied flitch spacing is 300mm.Described side wall template 70 is previously by quincunx concrete
Cushion block and side wall reinforcing bar are close to, and in the stupefied hot rolling of the stupefied and vertical master of side wall template level below time, edge of a wing H profile steel 20 becomes cross to hang down
The pre-buried keying that straight shape passes through at Guan Liang 80 and side wall 90 bracket is reinforced surely, and this side wall template adopts the wood glue of 18mm-20mm
Plate or bamboo slab rubber.If too small from the rigidity thick less than 18mm, from the side wall template more than 20mm thickness with regard to surplus capacity mistake
Greatly, uneconomical.
Above example only illustrates technological thought of the present utility model it is impossible to limit protection model of the present utility model with this
Enclose, every according to the utility model proposes technological thought, any change done on the basis of technical scheme, each fall within this reality
Within the scope of novel protected.
