Description
Technical field
The present invention relates to a kind of building scaffold wall-connecting piece.
Background technology
Wall-connecting piece is meant the member that connects scaffold and building, is the important component part of scaffold.The domestic and international scaffold collapse accident that takes place substantially all is because wall-connecting piece is provided with in time to mend to establish after deficiency or wall-connecting piece are removed causes." building operations fastener type steel pipe scaffold technical specification of security " (JGJ130-2001) the 6.4th joint made concrete regulation to wall-connecting piece, the rigidity wall-connecting piece should be adopted for the single, double row's scaffold below the 24m, the rigidity wall-connecting piece must be adopted the single, double row's scaffold more than the 24m.
The rigidity wall-connecting piece refers to the wall-connecting piece that adopts steel pipe, fastener or built-in fitting to form, but the way of concrete regulation rigidity wall-connecting piece not in the standard causes the way of present various places rigidity wall-connecting piece to differ, and there is potential safety hazard in the part way.
Conventional wall-connecting piece is divided into stay bolt associated methods, embedded steel tube method, back anchoring process and banded column method, pre-buried iron plate method and embedded bar method usually.
Wherein:
The stay bolt associated methods is applicable to low layer, the multistory building of scaffold building height less than 24m usually, adopt embedded bar and scaffold drawknot, after adding horizontal steel tube again and propping up the method for agent structure or adopt embedded bar and short steel pipes welding, fuse with fastener connection horizontal steel tube and scaffold again.
Shortcoming is, the weak point of stay bolt associated methods be scaffold lateral stiffness than rigid connection method a little less than, the steel pipe that plays the support effect can't closely connect scaffold and agent structure, cause scaffold easily to produce and rock, thereby and when external rendering, easily produced potential safety hazard by complete removal.
The embedded steel tube method is a 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 about 20cm in the beam with a vertical short steel pipes before concrete is built, and exposes the beam 20cm that breaks an agreement, treat concrete build finish after, connect vertical rod with the long steel pipe of level and get final product with vertical short steel pipes.
Shortcoming is that the cost height is dismantled trouble, and must be carried out the later stage shutoff to the back box out mouth of masonry, and serious infiltration hidden danger is arranged.
Back anchoring process is the improvement of doing at the deficiency of above-mentioned embedded steel tube method.Back anchoring process is installed expansion anchor or chemical anchor bolts at the flank hole of beam, is connected with anchor slab prior and that steel pipe is welded into one to get final product again.
Shortcoming is that the construction trouble extremely bothers when especially holing.Normally adopt 2 expansion anchors, bearing capacity is not high, and is easily loosening, can not bear low cycle repetitive load, is not suitable for the southeastern coastal areas of many typhoons, the construction requirement height, and after construction finished, crab-bolt was also scrapped, and can't reuse, and causes cost also higher.
The banded column method is meant not pre-buried in agent structure, after post template is removed, the concrete tie lived with four short steel pipes and four fasteners, and by the method that long steel pipe is connected with scaffold upright rod.
Shortcoming is that required material is maximum, the economy extreme difference.And, the same with the embedded steel tube method, still there is wall spare filling-up hole operation, serious infiltration hidden danger is arranged, infiltration hidden danger is arranged.
Pre-buried iron plate method is meant before the beam column concrete construction of agent structure, the iron plate of pre-buried band anchor pin in the relevant position.With steel pipe and the iron plate welding of exposing beam side or post side, the opposite side of steel pipe is connected with fastener with the vertical rod of scaffold after the form removable.Advantage: good rigidly, no masonry filling-up hole operation does not have infiltration hidden danger.
Shortcoming is, the cost height, and the construction trouble has disaster hidden-trouble.
The embedded bar method is meant before the construction of the beam column concrete of agent structure, in the relevant position pre-buried in advance and the reinforcing bar that welds of steel pipe sidewall.Utilize steel pipe that pre-buried reinforcing bar is bent after the form removable, the opposite side of steel pipe is connected with fastener with the vertical rod of scaffold.
Shortcoming is that poor rigidity has potential safety hazard, and disaster hidden-trouble is arranged.
A kind of existing wall-connecting piece has the anchor that presets of license, and this preset piece anti-pulling capacity in the plain concrete of C25 detects through Zhejiang Province's construction project quality testing station, and anti-pulling capacity is not less than 20kN, is enough to satisfy the instructions for use of wall-connecting piece.During use before concrete is built at the fixed-site anchor of needs.After treating the beam sides form removable, with the steel pipe that is welded into one with anchor slab in advance with preset anchor and be connected and get final product.
Shortcoming is construction trouble, need build synchronously with concrete, especially in advance will be pre-buried extremely bothers during anchor.The pre-buried precision of built-in fitting horizontal direction is higher, because the elongated muscle configuration of beam is more is very easily interrupted by pre-buried anchor, destroy structural bearing capacity, and after construction finished, pre-buried anchor was scrapped also, can't reuse, and the filling-up hole operation is arranged thereby infiltration hidden danger is also arranged.
Summary of the invention
The technical problem to be solved in the present invention is to realize a kind of easy for installation, economy, the building scaffold wall-connecting piece of no potential safety hazard.
To achieve these goals, the technical solution used in the present invention is: a kind of building scaffold wall-connecting piece, this wall-connecting piece comprises base plate, vertically be fixed in two side plates at base plate two ends, be fixed in the connector in one of them side plate outside, pass another side plate and by the fixing double-screw bolt of hold-down nut, and be arranged at two sliding roofs between the side plate, described sliding roof and side parallel with two blocks of side plates is connected with double-screw bolt.
Described nut and double-screw bolt are provided with two pairs, and an end of two double-screw bolts all is connected with moving top board.
Described side plate is a trapezoidal plate.
Described base plate is provided with the gathering sill that matches with sliding roof.
The invention has the advantages that to need not pre-buriedly in advance, easy for installation, no disaster hidden-trouble, use gas cutting when having avoided traditional wall-connecting piece to remove, but the expense material of taking a lot of work is the defective of fire hazard again, and wall-connecting piece can be reused, technology, remarkable in economical benefits, do not destroy structure, save social economy.With respect to the conventional fastener wall-connecting piece, there be certain anti-rising to turn over the wall-connecting piece of stream effect.
