Abstract
The utility model relates to an installation of a large-span bridge bracket. A large-span cable bridge bracket installation mold comprises a right-angle cantilever; a bolt horizontally connected with the end part of the horizontal edge of the right-angle cantilever; a lifting tool sliding support with the top end being fixedly connected with the vertical edge of the right-angle cantilever; a bearing arranged in a bottom edge groove of the lifting tool sliding support and capable of rolling towards the left and the right directions; a circular ring passing through the bearing center and surrounding the bottom edge of the lifting tool; a rigging turn-buckle with the top end being hung on the circular ring by a hanger; and a lifting tool bracket. The large-span bridge bracket installation mold provided by the utility model solves the inefficiency and high potential safety hazard difficulties of high-altitude large-span bridge bracket construction, and effectively improves the construction efficiency.
Description
Technical field
The utility model relates to crane span structure to be installed, and relates in particular to a kind of installation of big span crane span structure.
Background technology
The cable testing bridge construction is the pith of electrical construction.Big span crane span structure is to be applicable to that the length in high-altitude is the cable testing bridge of 6-7 rice, because length, the side plate of big span crane span structure adopts the duplex plating zine plate, and weight (60～80kg/ only) is much larger than 3 sections weight of adding up of common 2 meters crane span structures.Therefore the construction of the big span crane span structure in high-altitude generally must be by driving or truck crane in the factory building.Big span crane span structure is installed under High Altitude Platform can't be used under the situation of driving in the factory building or truck crane, can only lean on manpower on scaffold, to construct.Because big span crane span structure length and weight, construction is difficulty very, and potential safety hazard is big, and construction schedule is slow.
Summary of the invention
The utility model is intended to solve at the construction field (site) installs the construction difficult problem that big span crane span structure can't use factory building driving and truck crane under the High Altitude Platform, and a kind of large span cable bridge rack installation mold is provided.The utility model specialized designs the installation mold of large span cable bridge rack, solved the difficult problem that high-altitude big span crane span structure efficiency of construction is low, potential safety hazard is big, improved efficiency of construction effectively.
The utility model is achieved in that
A kind of large span cable bridge rack installation mold, it comprises:
One right angle cantilever;
One bolt, the end of the horizontal sides of described right angle cantilever are provided with the bolt bracket that is oppositely arranged with this bolt of horizontal support;
One suspender sliding support, it is isosceles triangle, the vertical edge of fixedly connected described right angle, its top cantilever, its base has the U-shaped groove;
One bearing, it is arranged in the base groove of described suspender sliding support and can rolls to the left and right;
One annulus, it passes described bearing centre and around the suspender base;
One wire tensioner, its top comprise a hook, and are hooked on the described annulus with this hook;
One suspender carriage, it includes a crane span structure carriage that is positioned at the suspender carriage, and they can be connected in the bottom of described wire tensioner up or down along wire tensioner with nut.
Described large span cable bridge rack installation mold, the both sides on the base of described suspender sliding support are respectively equipped with the clamp that is used for stablizing described bearing of oblique setting.
Described large span cable bridge rack installation mold, described wire tensioner are two anti-bolts.
The utility model has solved the difficult problem that high-altitude big span crane span structure efficiency of construction is low, potential safety hazard is big, has improved efficiency of construction effectively; Make big span crane span structure construction convenient, easier control installation accuracy can effectively improve installation quality, has reduced human input simultaneously, can reduce construction cost effectively.
