Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is done further in detailDescribe. Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
Embodiment mono-:
Fig. 1 is the top view of transom pier reinforcing bar operation platform described in the embodiment of the present invention one; Fig. 3It is the side view of assembly flow shop stand of the present invention; Fig. 4 is the sectional drawing of Fig. 3.
The present invention has announced a kind of for carrying out across the sea the assembled stand of bridge construction, bagDraw together multiple supports that are inter-connected via a bolt joint 1, the bottom of each support 1 is all connected with base 2;The shape of support 1 is identical with the shape of ring flange, and difform support 1 can be set, so thatBe assembled into difform stand, thereby adapt to the pier stud of various shapes, improve being suitable for of standScope.
Each support 1 includes interior side rail 11 and outer side rail 12, outside interior side rail 11 is positioned atThe inner side of side rail 12; Interior side rail 11 is by many vertical main framings connected vertically and horizontal masterSkeleton, is provided with some for connecting the perpendicular of the horizontal main framing of levels between adjacent vertical main framingBar, lower channel in formation; Between adjacent transverse main framing, be provided with some for connecting adjacent montantOr the cross bar 13 of vertical main framing; Described outer side rail 12 is identical with the structure of interior side rail 11,Vertically between interior side rail 11 and outer side rail 12 be connected with some cross bars 13; Above-mentioned all cross bars13 layering settings, to form the interim corridor of differing heights, convenient working.
Described base 2 comprises flanged plate and is welded on the stiffener of flanged plate top, support 1 withStiffener connects (not shown); Described base 2 is provided with bolt hole, preferably bolt hole is establishedBe set to once through flanged plate and stiffener, to strengthen the bonding strength of base 2; Bolt holeDiameter, spacing and position all with Pier Formwork on connecting bolt hole match. Preferably, canBe set to slotted hole with the several bolts hole on base 2, to alleviate between base 2 and pier studInteraction force, reduce internal stress.
As Fig. 4, the bottom of described outer side rail 12 is provided with intilted main brace 15, instituteState main brace 15 for straight-bar; The top of main brace 15 is connected with outer side rail 12, main brace15 bottom is connected with bottom and the base 2 of interior side rail 11 simultaneously, described main brace 15,The knot that one cross section is right angled triangle is formed on the cross bar 13 of bottom and the bottom of interior side rail 11Structure; This arranges the width that can reduce base 2, is conducive to alleviate the weight of support 1, sideJust assembly and disassembly.
As Fig. 3, adjacent described vertical main framing and montant, montant and montant, main brace 15And between the different ends of main brace 15, be connected with bridging 14, described bridging 14 is straight-bar;Wherein one end of adjacent bridging 14 is fixed on same point, bridging 14 be connected to adjacent layer itBetween, can realize the support between layer and layer or adjacent montant, vertical main framing. Be positioned at top layerThe platform that forms of described cross bar 13 be operating platform, montant exceeds operation with vertical main framingThe part of platform is provided with the guard rail 16 of some horizontal distribution, forms handling safety corridor, andAnd can play protective action.
Described flanged plate is preferably strip or arcuate structure, but is not limited to these two kinds, flanged plateShape and pier stud external mold assembling profile match; The shape of described support 1 and companion flange plateShape is identical.
Provide one group of concrete data below, to understand. Interior side rail 11 and outer side rail12 spacing is 70cm, and interior side rail 11 is as reinforcing bar location skeleton, and outer side rail 12 is doneFor safe fence. The height of every cover stand is 7m, bottom step pitch 1.6m, the step that top is three layersDistance is 1.8m. Between upper and lower layer, adopt φ 22mm reinforcing bar to do montant, lower channel in formation.The base 2 of stand is selected the flanged plate of being made by 12mm steel plate. On flanged plate, be equipped with bolt hole,Coincide Pier Formwork connecting bolt hole of position, hole diameter, spacing and position, be convenient to can with template on,Lower being connected. The vertical main framing of stand adopts ∠ 75*5mm angle steel, and laterally main framing adopts ∠63*5mm angle steel, the bridging 14 of reinforcing use adopts ∠ 50*5mm angle steel.
In the present embodiment, pier stud profile is door type structure, and three limits are wherein straight flange, surplusYuing a limit is arc-shaped side, and this stand is by the support 1 of three strips and an arcuate structureSupport 1 forms, and between support 1, realizes assembling by bolt.
Embodiment bis-:
Fig. 2 is the top view of oval pier reinforcing bar operation platform described in the embodiment of the present invention two; This realityExecute example basic identical with the structure of embodiment mono-, difference is, the stand of the present embodiment is by twoThe support 1 of strip-shaped bracket 1 and two arcuate structures assembles so that with the shape of pier studMatch.
By difform support 1 is assembled, can be assembled into different stands, so that withDifform pier stud matches, and the stand scope of application is wider.
The present invention has also announced the using method of above-mentioned assembled stand, Figure 5 shows that assembledThe job step figure of stand, specifically comprises the following steps:
S1: after accurately locating pier stud profile, multiple supports 1 are assembled into and pier stud profileThe stand matching, is then placed into stand on cushion cap, and the base of stand 2 is connected to and is heldOn the end face of platform;
S2: carry out reinforcing bar binding operation in the space surrounding at stand;
S3: the stand of dismantling, goes to other pier positions week and use;
S4: Pier Formwork is installed in the reinforcing bar outside completing in colligation, carries out concreting operation,Build first joint pier shaft;
S5: on epimerite Pier Formwork, assemble stand, colligation second section pier stud reinforcing bar, successivelyTo cocycle.
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 multiplely, by the assembling of difformity support 1, can fillBe made into difform stand, can adapt to the pier shaft of differently contoured shape, the stand scope of applicationExtensively.
3,, in the time that pier stud profile is identical, same stand can be tied up for multiple bridge pier reinforcing bars simultaneouslyPrick construction, efficiency of construction is high.
4, compared with conventional floor stand 1, stand of the present invention after having builtWithdraw, short with the contact with sea water time, reduce the corrosion of seawater to stand, extend standService life.
5, stand is fixed on pier shaft or Pier Formwork, and support 1 self has a fixed structure,Between frame 1, be bolted, can realize fixingly, horse structure is stable, processing safetyHigh; Interior side rail 11 is as reinforcing bar location skeleton, and outer side rail 12 is as safe fence, withoutSafety net, is subject to windage less.
The above is only the preferred embodiment of the present invention, it should be pointed out that for this technology and leadsThe those of ordinary skill in territory, not departing under the prerequisite of the technology of the present invention principle, all rightMake some improvement and replacement, these improvement and replacement also should be considered as protection scope of the present invention.
