Description
Technical field
The utility model belongs to building unit technical field, is specifically related to a kind of Simple general type outer scaffold wall connector for being connected with major structure of construction by external scaffolding.
Background technology
Wall-connecting piece generally refers to the component by being connected the stability strengthening other structures with reliable fixed end, in construction work, adopt wall-connecting piece to realize the connection of attached wall, for strengthening the resistance to overturning of scaffold, major accident tool plays a very important role to improve its stable bearing capacity and avoid occurring toppling over or cave in etc.
Wall-connecting piece is the component of connecting pin hand cradle and building, is the important component part of scaffold.The Scaffold Collapse Accident of domestic and international generation is substantially all cause security incident because wall-connecting piece arranges not mend to establish in time after deficiency or wall-connecting piece are removed.The unstability of scaffold is divided into overall collapse and local buckling usually.Wherein overall collapse is the main damage form of scaffold unstability, destroys and starts from without the larger transverse frame of wall-connecting piece, lateral stiffness difference or initial bending.And arrange rationally, bearing capacity is high, construct satisfactory wall-connecting piece, to the control that the improvement of span, the raising of lateral stiffness and outer wall impermeable leak, all play direct effect, thus the resistance to overturning of scaffold and the construction quality of exterior wall played an important role.
Concrete regulation has been made to wall-connecting piece in " building operations fastener type steel pipe scaffold technical specification of security " (JGJ130-2011) Section 6.4, double-pole scaffold for below 24m should adopt rigid connecting tube, must adopt rigid connecting tube to the double-pole scaffold of more than 24m.Rigid connecting tube refers to the wall-connecting piece adopting steel pipe, fastener or built-in fitting composition.But the way of not concrete regulation rigid connecting tube in specification, causing the way of current various places rigid connecting tube to differ, there is potential safety hazard and hidden danger of quality in part way.
Simple general type outer scaffold wall connector way common is at present when concrete floor is built, embedded steel tube in position, and embedded steel tube is stretched out between concrete structure with external scaffolding and is connected by fastener.Although the method rigidity is strong, meet demand for security, but cost is high, dismounting trouble, and must stay the embedded steel tube position of Simple general type outer scaffold wall connector establish hole when building exterior wall, after Simple general type outer scaffold wall connector is removed, carry out shutoff again, leave infiltration hidden danger to exterior wall.
Summary of the invention
Goal of the invention: the utility model object is for the deficiencies in the prior art, provides a kind of while good rigidly, stable connection, be convenient to dismantle and do not produce infiltration hidden danger Simple general type outer scaffold wall connector.
Technical scheme: a kind of Simple general type outer scaffold wall connector described in the utility model, for transmitting the pulling force and pressure that described external scaffolding is subject to, comprise the pre-buried steel disc be embedded in advance in side bar, first right-angle coupler and joint steel pipe, described pre-buried steel disc comprises pre-buried end and external part, described pre-buried end is set to the hook-shape end matched with main muscle cross sectional shape in side bar, this end sketches the contours colligation and is fixed on described main muscle after-pouring in side bar concrete, described external part stretches out described side bar, and having near end position place the fixing hole matched with the upper connecting portion diameter of bolt of the first right-angle coupler, described first right-angle coupler is by upper connecting portion bolt, nut and fixing hole are fixedly connected with pre-buried steel disc external part, the lower connecting portion of described first right-angle coupler is fixedly connected with joint steel pipe, described joint steel pipe is fixedly connected with external scaffolding.
