Description
Technical field
The present invention relates to a kind of building scaffold wall-connecting piece, belong to the technical field of building operations.
Background technology
Wall-connecting piece is the important component part of scaffold.In time mend and establish after being removed if wall-connecting piece arranges deficiency or wall-connecting piece, very easily cause Scaffold Collapse Accident.
Present domestic scaffold wall connecting piece way eaily is to adopt fastener to connect, scaffold regulation and stipulation list fastener resisting slipping Design of Bearing Capacity value is 8kN, the two fastener resisting slipping antiskid Design of Bearing Capacity values of " Zhejiang Province's building operations Formwork-supportof Fastener-style Steel Pipe tecnical regulations " (DB33/1035-2006) the 5.4th joint regulation are 12kN, just should adopt other drawknot modes during greater than 12kN when the wall-connecting piece Force Calculation.
" building operations fastener type steel pipe scaffold technical specification of security " (JGJ130-2011) the 6.4th joint has been made concrete regulation to wall-connecting piece, but wall-connecting piece must adopt the structure of bearing tension and pressure,, for the double-pole scaffold more than height 24m, should adopt rigid connecting tube to be connected with building.
The requirement of the low-carbon energy-saving of builing industry, environmental protection, safety construction is more and more higher.
The embedded steel tube method is wall-connecting piece way the most commonly used at present, can play the effect of being rigidly connected.The embedded steel tube method is to be embedded in beam approximately 20cm with a vertical short steel pipes before concrete is built, and exposes the beam 20cm that breaks an agreement, and after concrete has been built, connects vertical rod with horizontal steel pipe connecting and gets final product with vertical short steel pipes.
Shortcoming is: cost is high, dismounting trouble, when the wall-connecting piece Force Calculation inapplicable during greater than 12kN.
The banded column method is with four short steel pipes and four fasteners, the concrete tie to be lived, and with horizontal steel pipe connecting, connects scaffold upright rod.Shortcoming is: required material is many, the economy extreme difference, and the wall-connecting piece Force Calculation is inapplicable during greater than 12kN.
The pre-embedded steel slab method is before the beam column wall concrete construction of agent structure, is subscribing the pre-buried steel plate with the anchor pin in position.After form removable, with steel pipe and Plate Welding, the opposite side of steel pipe is connected with fastener with the vertical rod of scaffold.Advantage: good rigidly, without masonry filling-up hole operation, without infiltration hidden danger.Shortcoming is: cost is high, and the construction trouble, have disaster hidden-trouble.
Summary of the invention
Technical problem to be solved by this invention be realize that a kind of bearing capacity is large, easy for installation, economy, without the building scaffold wall-connecting piece of potential safety hazard.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of building scaffold wall-connecting piece, comprise angle steel (being wall connecting rod spare), U-bolt (U-bolt is used for fixedly scaffold upright rod) but adjusting screw(rod), built-in fitting, wherein the U-bolt perforation is arranged on a side of angle steel one end, offer groove on the opposite side of the angle steel other end, built-in fitting is positioned at groove, and run through groove, but adjusting screw(rod) be fixedly connected with built-in fitting, but simultaneously adjusting screw(rod) is fixedly connected with angle steel.
Further setting as such scheme, be fixedly installed coupling assembling on described angle steel, but adjusting screw(rod) is fixedly connected with coupling assembling.
Described coupling assembling comprises two trimming angle steel, but adjusting screw(rod) is folded between two trimming angle steel, but on adjusting screw(rod) and the one or both ends that are positioned at the trimming angle steel are provided with nut one (but by nut one, being undertaken adjusting screw(rod) and two trimming angle steel fastening), and two trimming angle steel line centered by the axis of groove is symmetrical simultaneously.
Described coupling assembling is two, lays respectively at the left and right sides of groove, but the connecting hole one and built-in fitting socket of adjusting screw(rod) by being positioned at centre, and fastening by nut two, but the two ends, left and right of adjusting screw(rod) are fixedly connected with a corresponding coupling assembling respectively.
Described coupling assembling is one, between groove place end and corresponding angle steel end, but the connecting hole two and built-in fitting socket of adjusting screw(rod) by being positioned at an end end, and fastening by nut two, but the other end of adjusting screw(rod) is fixedly connected with coupling assembling.
But on described adjusting screw(rod) and be positioned at trimming angle steel two ends and be equipped with two nuts one.
Described built-in fitting is bolt or mantle fiber reinforcing bar.
Between described trimming angle steel and angle steel for being welded to connect.
the invention has the advantages that bearing capacity is large, as long as the material of wall-connecting piece is not destroyed and just is considered as safety and (gets U-bolt during checking computations, fluting place wall connecting rod spare angle steel, pre embedded bolt or mantle fiber reinforcing bar, the weld seam of trimming angle steel, but the design bearing capacity minimum value of adjusting screw(rod)), pre embedded bolt or mantle fiber reinforcing bar convenient (before casting and compacting of concrete or water in smashing pre-buried all can), pre-buried position accuracy demand is not high, as long as the error in half scope of wall connecting rod spare slotting length does not all affect installation, easy for installation, without disaster hidden-trouble, wall-connecting piece can be reused, do not destroy structure, technology, remarkable in economical benefits, and certain anti-upflow effect arranged.
The invention will be further described below in conjunction with the drawings and specific embodiments.
