Abstract
The utility model belongs to the technical field of external scaffolding used in construction. The scaffold has the advantages of high construction speed and small use of steels. The utility model is characterized in that a plurality of or minor cranes which are arranged on the upper part of a main headframe are used to replace a large-size tower crane, which reduces the construction time of a subject construction and saves steels; a double extension arm type working platform and a bridge type working platform which are installed on two sides of a top lifting frame can lift and drop at any time and can regulate the level distance with a wall surface; a scaffold board which is laid on the working platform can be pulled out and pushed in to regulate the level distance with the wall surface.
Description
The utility model belongs to building operations external scaffolding technical field, and this external scaffolding is suitable for highrise building and construction of super highrise building usefulness, and it not only can realize the rapid construction reduction of erection time, and can use steel less.
Existing fastener type steel pipe scaffold " highrise building external scaffolding " (China Construction Industry Press publishes 18 pages in August, 1987) is more more advanced than other various external scaffoldings, rolled steel dosage is many, speed of application is slow, must there be large-scale pillar crane to cooperate lifting and lifting, the efficient of crane is also low, and cost is high again.
The purpose of this utility model provides a kind of in order to overcome above-mentioned existing deficiency can realize that speed of application is fast, rolled steel dosage is few, safe and reliable, a kind of multi-functional external scaffolding that need not large-scale pillar crane cooperates.
The purpose of this utility model is achieved in that uses the external scaffolding of setting up full hall around the building jacking attaching double stretching arm external scaffolding of the single group of segmentation instead.This scaffold is formed derrick by base section, standard knot [monolithic framework spelling forms], jacking stock and jacking joint, derrick is fixed on the body of wall with the gusseted stock, at the two semi-girder working platformes of the both sides of jacking stock installing, layering is hung and is established the bridge-type working platform between two derricks, the small-sized carriage amplitude varying formula crane of derrick upper end installing, suspending in midair in derrick the inside and to promote the cage that material is used, concave shape external application cage guide is installed in outside the derrick.
Accompanying drawing 1 is a vertical layout schematic diagram of the present utility model
Accompanying drawing 2 is layout schematic diagrames of the present utility model
(1) is small-sized carriage amplitude varying formula crane among the figure, and (2) are security guardrail, and (3) are two semi-girder working platformes, (4) be scaffold floor, (5) are balcony, and (6) are the gusseted stock, (7) be the masts type whip-and-derry, (8) be base section, (9) are concave shape external application elevator, and (10) are the bridge-type working platform, (11) be standard knot, (12) be concave shape external application cage guide, (13) are the jacking stock, and (14) are the jacking joint.
Jacking attaching double stretching arm external scaffolding is formed (resemble a people stand flat stretch about two arms) by above-mentioned each component.Derrick is made up of base section (8), standard knot (11), jacking stock (13) and jacking joint (14).Two semi-girder working platformes (3) are installed in jacking stock (13) both sides, and security guardrail (2) is housed in the outside of working platform, are covered with scaffold floor (4) on working platform.In the derrick upper end small-sized carriage amplitude varying formula crane (1) (masts type whip-and-derry (7) also can be installed) is installed.The guide rail slide block (not drawing among the figure) of concave shape external application elevator is clipped in the outside of two guide rails (12), and the slide block of elevator counterweight iron (not drawing among the figure) is clipped in the inboard of two guide rails.In derrick, be provided with and promote the cage (not drawing among the figure) that material is used.Between two derricks, suspending in midair and also laying scaffold floor (4) and security guardrail (2) above the bridge-type working platform (10).Safety net is overworked in the outside at all working platform from top to bottom, is also putting down below every layer of working platform in addition and is overworking safety net in order to guarantee the safety of square crossing operation, makes whole scaffold become the security system of a layering totally enclosed type integral body.
The jacking of derrick is carried out supernumerary segment and is connect highly in jacking stock (13) the inside, two standard knots of every jacking just entangle derrick with gusseted stock (6), with nut the gusseted stock is fixed on the beam of the post of framework or framework again.
The main feature of the utility model is: be installed in two semi-girder working platformes of jacking stock (13) both sides and be suspended in bridge-type working platform (10) between two derricks and can rise or descend at any time not only that (can make operating personnel often stand in the operation of suitable height part like this can reduce labor intensity, this is to conform with the ergonomics principle to require), and can also adjust horizontal range with metope at any time, the scaffold floor (4) that is layered on above the working platform also can advance or pull out the horizontal range of adjusting with metope at any time.(when working platform is raised to balcony bottom, scaffold floor is pulled out, crosses balcony and again scaffold floor is pushed near metope later on).Next is that concave shape external application elevator is located at the derrick outside, replaces large-scale pillar crane with many small-sized carriage amplitude varying formula cranes that are contained in the derrick upper end, does not carry on a shoulder pole like this and can make the major project reduction of erection time, can also use steel less
Claims (5)
1, the utility model belongs to building operations external scaffolding technical field, it comprises base section, standard knot, jacking joint, jacking stock, two semi-girder working platform, parts such as bridge-type working platform, small-sized carriage amplitude varying formula crane and concave shape external application elevator is characterized in that; Base section, standard knot and jacking save the composition derrick that mechanically links together in order inside the jacking stock, be erected on the basic platform.
