Description
Technical field
The utility model relates to a kind of building operations protective frame, is specifically related to a kind of protective frame in building main body construction stage.
Background technology
The building operations protective frame is mainly used in the security protection in the main body construction stage of high level and super highrise building; Present protective frame mainly is made up of single support body and vertical truss; Vertical truss is as the skeleton of support body; Satisfying carryings needs, this protective frame is connected with built-in fitting on the building through withstand leg and anti-dumping rod member, with the deadweight of protective frame with construct loading transfer to building.A plurality of support bodys unit burst like this is arranged on the building, forms the sealing frame around the building outline, construction structure is provided face frontier defense and protect.Along with the every rising one deck of building, utilize tower crane with carrying one deck on the protective frame and fixing with building again.Though above-mentioned protective frame is simple in structure, and is with low cost, has certain economic benefits.But also there are some shortcomings:
1, owing to the size of vertical truss with from great, must use tower crane when mounted, when lifting, bump easily, bring danger for the installation personnel.
2, this protective frame is to be connected with building with the anti-dumping rod member through withstand leg by vertical truss; The single support body in the outside only is connected with vertical truss, directly is not connected with the anti-dumping rod member with withstand leg, because vertical truss is connected with single support body through fastener; Tie point all in one plane; In case fastener meets accident loosening, very easily cause vertical truss to separate with support body, scaffold is fallen and cause accident to take place.
3, the vertical truss that adopts relatively expends steel, the waste resource.
Summary of the invention
The purpose of the utility model is to provide a kind of construction protection frame, and it is simple in structure, easy for installation, safe, the saving material, need not use tower crane when mounted, effectively avoids the collision of vertical truss and support body, for safety in production provides convenient.
The goal of the invention of the utility model adopts following technical scheme to realize:
The construction protection frame that the utility model proposes comprises the support body of truss principal device, anti-tilt device 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, bowl fastening type scaffold or other typing rod member are formed; Said truss principal device is connected with double support body with anti-tilt device, with the loading transfer of support body to building; Said truss principal device comprises truss principal and loading arm, and loading arm connects truss principal; Said anti-tilt device comprises girt, fixed bar, and inside and outside row's vertical rod multiple spot of fixed bar and support body is fixed, and girt is connected between fixed bar and the building.This protective frame is at first improved support body, has removed vertical truss, and has adopted non-single support body, and this support body is easy to build, and need be by tower crane.Simultaneously; In order to ensure the frame support body will conduct oneself with dignity effectively with Load Transfer to building; And the assurance safety and the stability that are connected with building, adopted the truss principal device of special construction, and all be connected fixing effluxing vertical rod in truss principal device and the support body.
For the fastness of guaranteeing that further truss principal is connected with support body, the utility model has also carried out appropriate design to the tie point of truss principal, and it is fixing to guarantee that truss principal is connected with inside and outside row's vertical rod of support body through a plurality of tie points.The truss principal that the utility model adopts can be arbitrarily existing feasible form; More general can be triangular truss, rectangle truss; Can certainly be the truss of any structure of other prediction, as long as it can reach the purpose that all is connected and transmits power with inside and outside row's vertical rod of support body.
Loading arm can be the straight-arm structure, considers that protective frame will avoid crashproof with building in lifting process, the parallel connection of design loading arm with truss principal, and make it do level with respect to truss principal to stretch.One end of said loading arm is packed in truss principal sleeve or the sleeve pipe; One end is connected in the pre-buried ring of building; With the loading transfer on the support body to building; And for telescopic loading arm is positioned, make the power transmission better of whole truss principal device simultaneously, hinged positioning tie bar between loading arm and truss principal.
Loading arm also can be for triangle arm form, and is hinged through otic placode and truss principal.
The fixed bar of said anti-tilt device is horizontal bars or zigzag rod member, and this fixed bar is connected with inside and outside row's vertical rod of support body.
In sum, it is thus clear that the utlity model has following advantage:
1. the support body of the utility model does not have vertical truss, but adopts common double support body, have simple in structure, from heavy and light, the advantage of building easily, in the protective frame build process, can not use tower crane just can realize building installation, it is more convenient, quick to construct.
2. the truss principal device of the utility model and anti-tilt device have all carried out multiple spot with the vertical rod on inside and outside two planes of support body and have been fixedly connected, and compare existing monoplane mounting structure, have force structure more reliably, so have higher safety.
3. when promoting protective frame, can temporarily throw off the positioning tie bar between truss principal and the loading arm, loading arm is moved away from body of wall one side with respect to truss principal is past, the outline that can effectively avoid building is outstanding, has reduced collision hidden danger.
4. the frame structure of the utility model can adopt common scaffolding structure, has saved vertical truss, can save 51% steel than prior art, reaches the effect of energy-saving and emission-reduction.
5. the anti-tilt device of the utility model has been considered the protection to safety net when design; As can adopt " Z " type fixed bar as required; Can make " Z " type fixed bar and efflux the intersection of the tie point position of vertical rod at two protective frame safety nets; The problem of having avoided level to connect and having worn out safety net can be protected the safety net that need recycle.
