Description
Technical field
The present invention relates to a kind of building operations protective frame, be specifically related to a kind of protective frame in building main body construction stage.
Background technology
Building operations protective frame is mainly used in the security protection in the main body construction stage of high level and super highrise building, current protective frame is mainly comprised of double support body and vertical truss, vertical truss is as the skeleton of support body, to meet carrying, transmit needs, this protective frame is connected with the built-in fitting on building with anti-dumping rod member by withstand leg, and the deadweight of protective frame and construction load are delivered on building.A plurality of support bodys unit burst is like this arranged on building, forms the enclosed frame around building outline, and construction structure is provided and faces frontier defense and protect.Along with the every rising one deck of building, utilize tower crane in protective frame, to carry one deck and again to fix with building.Although above-mentioned protective frame is simple in structure, with low cost, there is certain economic benefit.But also there are some shortcomings:
1, due to the size of vertical truss with from great, must use tower crane when mounted, when lifting, easily bump, bring danger to installation personnel.
2, this protective frame is to be connected with the built-in fitting of building with anti-dumping rod member by withstand leg by vertical truss, withstand leg is born support body deadweight and load, anti-dumping rod member guarantees that support body does not topple, but before withstand leg, anti-dumping rod member and built-in fitting, there is space, and withstand leg, anti-dumping rod member are fixed on the vertical Kao Zhong of support body position, it is high and without other fulcrums that support body top, bottom respectively poise first floor, so easily rock support body top, bottom, must add in addition wall connecting rod part and just can guarantee that support body does not rock.
Summary of the invention
The object of the present invention is to provide a kind of construction protecting rack, its simple in structure, easy for installation, safe, highly versatile, do not need to use tower crane when mounted, effectively avoids lifting the collision of vertical truss and support body; And solved support body and rock problem, for safety in production provides convenient.
Goal of the invention of the present invention realizes by the following technical solutions:
The construction protecting rack that the present invention proposes comprises the support body of oblique drawing device, horizontal fastening devices and carrying, described support body adopts traditional double framed bent body, this double support body can be the scaffolding structure form that existing fastener type steel pipe scaffold or other sizing rod member form, described oblique drawing device is connected with double support body with horizontal fastening devices, and the load of support body is delivered on building; Described oblique drawing device comprises that length adjustment device and oblique pull Jian， one end are connected to the interior row in double support body bottom or arrange vertical rod and leger Nodes outward, and the other end is connected with the built-in fitting of a upper floor; Described horizontal fastening devices comprises triatic stay and girt, and one end is connected with the interior row of double support body, and the other end is connected with built-in fitting.
First this protective frame is improved support body, has removed vertical truss, and adopts traditional double framed bent body, and this support body can disposablely complete and build, and need to not lift by tower crane., in order to ensure frame support body, effectively deadweight and load are delivered on building, and the safety and stability that is connected with building of assurance meanwhile, have adopted the relief arrangement of oblique pull.
Further, for increasing operability of the present invention, described oblique drawing device comprises length adjustment device and oblique pull part, makes support body can adapt to the building of different floor heights.Length adjustment device can be wire tensioner, adjusting screw(rod), and also other can reach the structure of the object that regulates length and be connected with oblique pull part.Oblique pull part can be any existing rigidity or flexible member, the soft rope that more generally can make with wire rope, soft chain, steel pipe, reinforcing bar, high strength fibre or rod member etc., can certainly be any form of structure of other predictions, as long as it can reach the object of bearing support body deadweight and load.
After oblique drawing device is stressed, except bearing support body deadweight and load, support body is had to one towards the horizontal component of building direction, make to abut against building limit bottom support body, effectively prevent that support body lower end from rocking.
Further, for guaranteeing the stability at support body top, the present invention has also carried out appropriate design to horizontal fastening devices.Described horizontal fastening devices comprises triatic stay and girt, and both equal one end are connected with row in support body by anchor ear, and the other end is connected with the built-in fitting on building.Due to lower end oblique drawing device effect, the inside horizontal component in support body upper end can abut against on building triatic stay, withstands support body, effectively prevents that support body from inwardly rocking; Girt length is adjustable, holds support body, effectively prevents that support body from outwards rocking.Two power one supports one are drawn, spacing reliable, avoid rocking.
In sum, visible the present invention has the following advantages:
1. support body of the present invention does not have vertical truss, but adopts common double support body, have advantages of simple in structure, from heavy and light, easily build, in protective frame build process, can not use tower crane just can realize and build installation, construct more convenient, quick.
2. oblique drawing device of the present invention is connected with support body with horizontal fastening devices, compares existing protective frame stress form, does not need to add wall connecting rod part, more effectively prevents that support body top, bottom from rocking, and has higher safety.
3. frame structure of the present invention has saved vertical truss, suspension truss length restriction not, and the oblique drawing device length of employing is adjustable, can meet the building demand of various floor heights, has higher versatility.
