Description

Bailey truss type Hanging Basket and spelling method thereof
Technical field
The present invention relates to a kind of equipment and spelling method thereof that is exclusively used in the bridge cast-in-place construction, particularly relate to a kind of Hanging Basket and spelling method thereof that is exclusively used in bridge cantilever cast-in-place construction.
Background technology
Hanging Basket is a kind of spelling equipment, and its single construction weight is light, need not large scale hoisting machinery when spelling and dismounting, just can carry out spelling smoothly, because spelling is very convenient with dismounting, in long-span bridge girder cantilever cast-in-place construction, those skilled in the art often adopts cradle construction technology.
Existing Hanging Basket equipment generally includes the load-bearing assembly, template assembly, anchoring assembly and walking moving assembly, wherein the load-bearing assembly mostly adopts triangular truss or rhombus truss to make up, the structural strength of this load-bearing assembly is that width or the sections according to the bridge desiring to set up heavily waits parameter to determine, that is to say, if set up different bridges, then need to design respectively triangular truss or rhombus trussed construction intensity, be processed into triangular truss or the rhombus truss that adheres to specification by H shaped steel again, this has brought many inconvenient and costs that build a bridge also therefore to increase many for the people of this area.
Summary of the invention
The object of the present invention is to provide a kind of improved Hanging Basket, make its structure can come spelling to realize by existing general component and fitting fully, with design that makes things convenient for Hanging Basket and the cost of manufacture that reduces Hanging Basket.
To achieve these goals, the characteristics of Hanging Basket of the present invention are, comprise the load-bearing assembly, it has the leading beam of at least two Bailey truss, preceding top rail, back top rail, preceding lower transverse beam and back lower transverse beam, the leading beam of described Bailey truss is formed by connecting by bracing frame by at least two row's Bailey truss (Bailey truss), and the described Bailey truss of every row is formed by connecting from beginning to end by multi-disc Bailey truss unit; Suspending assembly, its have a plurality of before suspender belt at the bottom of suspender belts, a plurality of back strap and a plurality of beam; Anchoring assembly comprises that an end imbeds many anchor ribs that become the beam body; And the walking assembly, it has one or more groups walking track, many round steel and counterweight; The rear end of the leading beam of described Bailey truss connects many described anchor ribs, top rail and described back top rail are across the upside of the leading beam of many described Bailey truss respectively before described, top rail and its lower end were connected to described preceding lower transverse beam before the upper end of a plurality of described preceding suspender belts was connected to, the upper end of a plurality of described back straps connects described back top rail respectively and is connected to described back lower transverse beam with its lower end, the upper end of little suspender belt connects the bottom side that become the beam body respectively and its lower end is connected to described back lower transverse beam at the bottom of a plurality of described beams, described walking track laying is in the leading beam of described Bailey truss and describedly become between the beam body and described round steel is layed on the described walking track, described counterweight is arranged at the rear end of the leading beam of described Bailey truss, to prevent Hanging Basket toppling when walking.
To achieve these goals, the characteristics of the method for spelling Hanging Basket of the present invention are may further comprise the steps:
(a) lay one or more groups walking track at the upside that becomes the beam body, on described walking track, lay many round steel;
(b) at least two are positioned on the described round steel by the leading beam of Bailey truss that bracing frame is formed by connecting by at least two row's Bailey truss, the described Bailey truss of every row is formed by connecting from beginning to end by multi-disc Bailey truss unit, and will imbed the described anchor rib external part that has become the beam body and be connected, and become the beam body to fix with respect to described so that described Bailey truss is dominated beam with the rear end of the leading beam of described Bailey truss;
(c) many forward and backward top rails are crossed at regularly the upside that described Bailey truss is dominated beam respectively;
(d) upper end with preceding suspender belt connects described preceding top rail, and the upper end of back strap connects described back top rail, and the upper end of suspender belt connects the described bottom side that has become the beam body at the bottom of the beam;
(e) forward and backward lower transverse beam is connected the lower end of described forward and backward suspender belt respectively, and described back lower transverse beam is connected in the lower end of suspender belt at the bottom of the described beam;
(f) in the rear end of the leading beam of described Bailey truss counterweight is set, when walking, topples to prevent Hanging Basket.
The leading beam of Hanging Basket of the present invention is to adopt Bailey truss to make up, because Bailey truss rigidity is big, the Hanging Basket distortion is little, help controlling cast-in-place sections construction quality, what is more important, the Bailey truss unit of Bailey truss rent convenient and rent low, even to setting up of the bridge of Different Weight and shape, the designer of Hanging Basket all need not consider how to constitute the process that Hanging Basket is dominated beam by English truss or rhombus truss, the manufacturer of Hanging Basket need not considered cumbersome manufacture process yet, the Bailey truss unit that only need rent Bailey truss from market just can become the leading beam of desired structure intensity by spelling, thereby has accelerated the manufacture process of Hanging Basket and reduced the cost of production of Hanging Basket.
For further specifying above-mentioned purpose of the present invention, design feature and effect, the present invention is described in detail below with reference to accompanying drawing.
