Description
Technical field
The present invention relates to the technical field that building is built, be especially the waterproof method after the dismounting of a kind of wall-connecting device of scaffold.
Background technology
When building constructions is constructed, needing to make the operations such as the rendering of exterior wall, veneer, therefore the environment of operation is more special, during construction
The scaffold operation platform as workman must be built, otherwise cannot base oneself upon.Along with height and the elevation of building of modern architecture are complicated
The increase of property, building scaffold set up difficulty and requirement is more and more higher.In prior art, arrange the most at the construction field (site)
Being the steel pipe scaffold of double fastener type, it includes many vertical equity bars, transverse horizontal bar and vertical rod, and these rod members constitute
Multilamellar, the framework shape steel construction scaffold of multi-span.And the connector between this framework shape steel construction and body of wall commonly referred to connects
Wall part, its effect can not be ignored, and is mainly reflected in:
First, at the fastener node that wall-connecting piece is connected with rod member, there is under the effect of load suitable anti-rotating ability (i.e.
Usually said has rigidity), but owing to quality and the degree of tightening of fastener itself all have impact on the rigidity of this node, therefore should
Framework is structures with semi-rigid joints framework, and the transverse width of scaffold will be much smaller than its longitudinal length and vertical height, therefore,
Scaffold for a face wall can be considered again the flat board of one piece of lattice, and it is poor in the rigidity being perpendicular to building surface direction,
Being far smaller than it longitudinally rigid, therefore scaffold must rely on and being reliably connected of building, and i.e. arranges wall-connecting piece, just has
Bear its deadweight, construction load and the ability of wind load.
Second, wall-connecting piece is the support pull bar between scaffold and main structure body and the constraint limiting scaffold longitudinal direction Free Transform length
Connecting rod, it is as bearing the bearing of horizontal force action, serves following effect: one, it is by scaffold and building structure work
Journey is tied, it is ensured that scaffold monolithic stability and use safety；Its two, it retrains scaffold change under vertical load effect
Shape, reduces vertical rod computational length, strengthens scaffold lateral stiffness, improves its resistance to capsizing outwardly or inwardly and carrying is stable
Property；Its three, its opposing wind load and other horizontal load effects also pass to engineering structure；Its four, resist because ground is uneven heavy
The internal force dropped and cause, makes internal force redistribute, to reduce the concentrated stress of lower portion, it is to avoid local failure occurs in framework；
Its five, strengthen scaffold overall, or local, or the rigidity in weak direction.
The outrigger that building industry routine is conventional at present has socketed embedded steel tube (or reinforcing bar) and has connected and two kinds of structures of connection by post-installed fastenings.But
It is that both structure wall-connecting device of scaffolds exist problem below:
1) first, embedded steel tube (or reinforcing bar) connects, and it is made up of with built-in fitting wall connecting rod, fastener, and its wall connecting rod can hold
Pressure can be born again by pulling force, there is bigger rigidity, deform the least under load effect.It waters at concrete in actual use
It is embedded in about 20cm in beam with a vertical short steel pipes before building, exposes beam and break an agreement 20cm, after concrete placings completes, by fastener water
Flat long fastener for connection vertical rod and vertical short steel pipes, the long steel pipe of level has acted as the role of wall-connecting piece.But, use pre-buried
The problem that the structure of part exists has: one, its positional accuracy is not easily controlled, and the patch work amount in later stage is bigger；Its two,
During scaffold building, wall-connecting piece is caused to be had any problem normally arranging due to the change of job site；Its three,
When building body enters the decoration of exterior wall stage, construction enterprises for ease of external wall construction, are about to after the wall-connecting piece of original setting removes certainly,
Cause support body anchorage seriously to reduce；Its four, embedded steel tube connects cannot be pulled out due to pre-buried vertical steel pipe, and needs
Masonry hole is carried out later stage closure, thus hidden danger can be brought to external wall waterproof.
2) connection by post-installed fastenings, is the deficiency connected for above-mentioned embedded steel tube and the improvement made, and connection by post-installed fastenings is the side at beam
Boring, installs expansion anchor, then with being connected with steel pipe welding all-in-one-piece anchor slab in advance.But, connection by post-installed fastenings exists
Problem is to construct extremely to bother, and especially drilling operation bothers very much: being typically with 2 expansion anchors, bearing capacity is the highest,
Easily loosen, low all alternate loads can not be born, rigid connecting tube scope can not be included strictly speaking in；According to chemical anchor bolts,
Then construction requirement is the highest, must strictly control hole depth and aperture in work progress, and must strictly clear hole, otherwise bearing capacity
Cannot be guaranteed；And after having constructed, crab-bolt is also scrapped, it is impossible to reuse, increase construction cost；And removing
Time, it is necessary to use naked light to cut, therefore there is serious disaster hidden-trouble.
Summary of the invention
It is longer that the technical problem to be solved is to provide a kind of sealing path, thus substantially increases the foot of water resistance
Waterproof method after the dismounting of hand cradle wall attaching parts.
