Each support 1 includes interior side rail 11 and outer side rail 12, and interior side rail 11 is positioned at the inner side of outer side rail 12; Interior side rail 11, by many vertical main framings connected vertically and horizontal main framing, being provided with some montants for connecting the horizontal main framing of levels, forming lower channel between adjacent vertical main framing; Some cross bars 13 for connecting adjacent montant or vertical main framing are provided with between adjacent transverse main framing; Described outer side rail 12 is identical with the structure of interior side rail 11, vertically between interior side rail 11 with outer side rail 12 is connected with some cross bars 13; Above-mentioned all cross bars 13 layering is arranged, to form the interim corridor of differing heights, convenient working.
Described base 2 comprises flanged plate and is welded on the stiffener above flanged plate, and support 1 is connected (not shown) with stiffener; Described base 2 is provided with bolt hole, is preferably set to by bolt hole once through flanged plate and stiffener, to strengthen the bonding strength of base 2; The diameter of bolt hole, spacing and position all match with the link bolt hole on Pier Formwork.Preferably, the several bolts hole on base 2 can be set to slotted hole, to alleviate the interaction force between base 2 and pier stud, reduce internal stress.
As Fig. 4, the bottom of described outer side rail 12 is provided with intilted main brace 15, and described main brace 15 is straight-bar; The top of main brace 15 is connected with outer side rail 12, and the bottom of main brace 15 is connected with the bottom of interior side rail 11 and base 2 simultaneously, and the structure that a cross section is right-angled triangle is formed on the cross bar 13 of described main brace 15, bottom and the bottom of interior side rail 11; This arranges the width that can reduce base 2, is conducive to the weight alleviating support 1, easy assembly and disassembly.
As Fig. 3, adjacent described vertical main framing is from montant, montant and montant, be connected with bridging 14 between main brace 15 and the different ends of main brace 15, and described bridging 14 is straight-bar; Wherein one end of adjacent bridging 14 is fixed on same point, and bridging 14 connects between adjacent layers, can realize the support between layer and layer or adjacent montant, vertical main framing.The platform that the described cross bar 13 being positioned at top layer forms is operating platform, and the part that montant and vertical main framing exceed operating platform is provided with the protective guard 16 of some horizontal distribution, formation handling safety corridor, and can play protective action.
Described flanged plate is preferably strip or arcuate structure, but is not limited to these two kinds, and the shape of flanged plate and pier stud external mold are assembled profile and matched; The shape of described support 1 is identical with the shape of companion flange plate.
Provide one group of concrete data below, to understand.Interior side rail 11 is 70cm with the spacing of outer side rail 12, and interior side rail 11 is as reinforcing bar location skeleton, and outer side rail 12 is as safe fence.The height often overlapping stand is 7m, bottom step pitch 1.6m, and the step pitch that top is three layers is 1.8m.Adopt φ 22mm reinforcing bar to do montant between upper and lower layer, form lower channel.The base 2 of stand selects the flanged plate made by 12mm steel plate.Flanged plate is equipped with bolt hole, and position, hole diameter, spacing and position coincide Pier Formwork link bolt hole, are convenient to be connected with template is upper and lower.The vertical main framing of stand adopts ∠ 75*5mm angle steel, and horizontal main framing adopts ∠ 63*5mm angle steel, and the bridging 14 reinforced adopts ∠ 50*5mm angle steel.
In the present embodiment, pier stud profile is door type structure, and three limits are wherein straight flange, and remaining a limit is arc-shaped side, and namely this stand is made up of the support 1 of three strips and the support 1 of an arcuate structure, realizes assembling between support 1 by bolt.
Embodiment two:
Fig. 2 is the top view of oval pier reinforcing bar operation platform described in the embodiment of the present invention two; The present embodiment is substantially identical with the structure of embodiment one, and difference is, the stand of the present embodiment is assembled by the support 1 of two strip-shaped bracket 1 and two arcuate structures so that with the mating shapes of pier stud.
By being assembled by difform support 1, can be assembled into different stands, to match with difform pier stud, the stand scope of application is wider.
The present invention also disclosed the using method of above-mentioned assembling stand, Figure 5 shows that the job step figure of assembling stand, specifically comprises the following steps:
S1: after accurately locating pier stud profile, multiple support 1 is assembled into the stand matched with pier stud profile, then stand is placed on cushion cap, the base 2 of stand is connected on the end face of cushion cap;
S2: carry out reinforcing bar binding operation in the space that stand surrounds;
S3: stand of dismantling, goes to other pier positions week and uses;
S4: install Pier Formwork outside the reinforcing bar that colligation completes, carry out concreting operation, builds first joint pier shaft;
S5: assemble stand, colligation second section pier stud reinforcing bar, successively to cocycle on most epimerite Pier Formwork.
As can be seen from the above embodiments, the present invention has following advantage:
1, horse structure is simple, and dismounting is convenient, safe and reliable, low cost of manufacture.
2, the shape of support 1 comprises multiple, and by the assembling of difformity support 1, can be assembled into difform stand, can adapt to the pier shaft of differently contoured shape, stand is applied widely.
3, when pier stud profile is identical, same stand, can simultaneously for multiple bridge pier reinforcing bar binding construction, and efficiency of construction is high.
4, compared with the floor stand 1 of routine, namely stand of the present invention withdraws after having built, short with the contact with sea water time, decreases the corrosion of seawater to stand, extends the application life of stand.
5, stand is fixed on pier shaft or Pier Formwork, and support 1 self has a fixed structure, is bolted between support 1, can realize fixing, and horse structure is stablized, and processing safety is high; Interior side rail 11 is as reinforcing bar location skeleton, and outer side rail 12 is as safe fence, and without the need to safety net, by wind impact is less.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and replacement, these improve and replace and also should be considered as protection scope of the present invention.
