It is equipped with different spacing between adjacent every two location pin-and-holes of described rack tube, spacing between adjacent two location pin-and-holes of described rack tube is the multiple number of basic spacing+pitch difference, described basic spacing equals the spacing between the adjustment pin-and-hole of Adjustable bracing bar, and described pitch difference is the length of described basic spacing by the quantity decile of described location pin-and-hole.
Described rack tube is provided with pull bar 13, and described pull bar protrudes upward the top of described rack tube.
The leg of described rack tube is three round steel to lateral bend outside rack tube, and described leg welds with rack tube at the inwall of described rack tube.
Embodiment one:
As shown in Figure 1, Figure 2, Fig. 3, a kind of adjustable supports Steel bar rack, supports the upper strata reinforcing bar 01 of base plate double-layer double-direction reinforcing bar in concrete construction.
Adjustable supports Steel bar rack comprises rack tube 10 and Adjustable bracing bar 20.
The cylinder of rack tube is external diameter is the round steel pipe of 50mm; Rack tube is provided with leg 11, and the leg of rack tube is three round steel to lateral bend outside rack tube, and leg welds with rack tube at the inwall of described rack tube, can reduce the resistance when taking out adjustable supports Steel bar rack like this.
The cylinder of rack tube is provided with four location pin-and-holes 12. Rack tube is provided with pull bar 13, and pull bar protrudes upward the top E=200mm of described rack tube.
Adjustable bracing bar adopts external diameter to be the round steel pipe of 42mm, and Adjustable bracing bar is arranged in the cylinder of rack tube, is provided with arc support slot 22 on the top of Adjustable bracing bar, for supporting upper strata reinforcing bar.
Adjustable bracing bar is provided with ten and regulates pin-and-hole 21.
Adjustable bracing bar is by being fixed in the cylinder of rack tube through the steady brace 30 of location pin-and-hole and adjustment pin-and-hole. Steady brace is one and passes described location pin-and-hole and regulate the bolt of pin-and-hole, is provided with nut 31 in the termination of described steady brace.
By the mutual position of the adjustment pin-and-hole of adjustment Adjustable bracing bar and the location pin-and-hole of rack tube, it is possible to realize the adjustment of the arc support slot height on Adjustable bracing bar top, to support the upper strata reinforcing bar of different heights.
In the present embodiment, ten of Adjustable bracing bar regulate the spacing arrangements such as pin-and-hole, the spacing B=24mm of adjacent two adjustment pin-and-holes. Four location pin-and-hole non-equidistance arrangements on rack tube cylinder, it is equipped with different spacing between adjacent every two location pin-and-holes of rack tube, spacing between adjacent two location pin-and-holes is the multiple number of basic spacing+pitch difference, basic spacing equals the spacing B=24mm between the adjustment pin-and-hole of Adjustable bracing bar, pitch difference is that basic spacing is located the length of the quantity decile of pin-and-hole, i.e. 24mm ÷ 4=6mm. Count from location pin-and-hole topmost:
The interval S 1 of first location pin-and-hole and the 2nd location pin-and-hole is basic spacing+one pitch difference, S1=24mm+6mm=30mm;
The interval S 2 of the 2nd location pin-and-hole and the 3rd location pin-and-hole is basic spacing+two pitch difference, S2=24mm+6mm × 2=36mm;
The interval S 3 of the 3rd location pin-and-hole and the 4th location pin-and-hole is basic spacing+three pitch difference, S3=24mm+6mm × 3=42mm.
The minor increment of height control is 6mm, and maximum setting range can reach 126mm, it is possible to meet the needs of upper strata reinforcing bar height control.
In construction, adjustable supports Steel bar rack is placed in Steel Concrete template to support upper strata reinforcing bar. In concrete casting process, building along with concrete, upper strata reinforcing bar is produced supporting role by aggregate self, now can be withdrawn from by adjustable supports Steel bar rack by pull bar in time. Pull bar can also be used to observe and control thickness of concrete cover.
