A kind of rectangle pier shaft reinforcement installation support
Technical field
This utility model relates to common bridge square pier shaft reinforcement installation auxiliary construction component, particularly a kind of rectangle pier shaft reinforcement installation support.
Background technology
At present, common bridge square pier shaft reinforcement construction typically uses Specialty Design platform (such as cantilever form, overmolded) or sets up landing leg hand cradle;Reinforcing bar location is general uses fixing shaped steel locating support or temporary steel support.
Operation platform use Specialty Design platform (such as cantilever form, overmolded), take support time length, template turnover utilization ratio low;Landing leg hand cradle is set up at employing scene, then material input is big, holding time is long.
Reinforcing bar location uses fixing shaped steel locating support, and material puts into big;Use temporary steel support, construction and installation and dismounting inconvenience.
Utility model content
The purpose of this utility model is to provide a kind of rectangle pier shaft reinforcement installation support, solving above-mentioned the deficiencies in the prior art, it utilizes pier shaft structure reinforcing bars to fix, and has operating platform and reinforcing bar positioning function concurrently, can integral hoisting turnover use, cost input is low, efficiency of construction is high.
For achieving the above object, the technical solution of the utility model is:
A kind of rectangle pier shaft reinforcement installation support, it is characterized in that: it includes rectangle support, if this rectangle support has dried layer, each layer is respectively provided with the safe Dense mesh screen being laid on safe fence, and equal ring sets a layer operation platform bottom each layer of safe fence, outside each layer operation platform, all each with safe fence layer safe fence is connected;This rectangle support lower end be arranged in parallel some Cantilever Beams, and this Cantilever Beams is spaced at equal intervals between the vertical main muscle of lower joint pier shaft top of concrete, uses limit steel bar to be welded with the vertical main muscle stretching out top of concrete by Cantilever Beams respectively.
This utility model has the advantage that use this utility model structure, and job site can fast and effeciently carry out rectangle pier shaft reinforcement installation, puts into operation little, easy, effect fast;Relative to tradition landing leg hand cradle, often joint pier shaft averagely can save the duration nearly 1 day, especially pronounced at high pier.

Detailed description of the invention
The utility model will be further described below in conjunction with the accompanying drawings.
Referring to Fig. 1-5, it is this utility model one rectangle pier shaft reinforcement installation support.As shown in the figure: it includes rectangle support, if this rectangle support has dried layer, each layer is respectively provided with the safe Dense mesh screen 9 being laid on safe fence 6, and bottom each layer of safe fence 6, equal ring sets a layer operation platform 8, is all connected with 6 each layers of safe fence of safe fence 6 outside each layer operation platform 8;This rectangle support lower end be arranged in parallel some Cantilever Beams 7, and this Cantilever Beams 7 is spaced at equal intervals between the vertical main muscle 11 of lower joint pier shaft concrete 12 end face, uses limit steel bar 10 to be welded with the vertical main muscle 11 stretching out concrete 12 end face by Cantilever Beams 7 respectively.
The manufacture method of rectangle support of the present utility model is:
(1) scaffolding steel pipe vertical rod 1, vertical rod 2, leger 3, little cross bar 4, lateral bar 5 according to Fig. 2, are carried out welding and form the framework of rectangle support.
(2) such as Fig. 3, Welding Safety fence 6, process Cantilever Beams 7, and process limit steel bar 1, lay-up operation platform 8, safe Dense mesh screen 9 is installed.
The installation of this utility model rectangle pier shaft steel bar operation platform and reinforcing bar localization method:
(1) such as Fig. 4, it is spaced at equal intervals Cantilever Beams 7 at lower joint pier shaft concrete 12 end face.
(2) such as Fig. 5, use limit steel bar 10 to be welded with the vertical main muscle 11 stretching out top of concrete by Cantilever Beams 7, play position-limiting action.
(3) check support quality, it is ensured that operating platform 8, safe Dense mesh screen 9 are reliable with the attachment security of support.
(4) integral hoisting rectangle support is placed on Cantilever Beams 7 and by rectangle support and Cantilever Beams 7 firm welding, its effect such as Fig. 1.
(5) one circle temporary spacing stirrup is set in table top, is used for positioning and fix the main muscle of pier shaft.
The method for dismounting of rectangle pier shaft reinforcement installation support of the present utility model:
(1) releasing is connected with vertical all interim of main muscle 11.
(2) releasing the connection of Cantilever Beams 7 and rectangle support, entirety hangs out rectangle support.
(3) release the connection of limit steel bar 10 and vertical main muscle 11, extract Cantilever Beams 7 out.
It is only preferred embodiment of the present utility model in sum, is not used for limiting practical range of the present utility model.The most all equivalence changes made according to the content of this utility model claim and modification, all should be technology category of the present utility model.
