Description

A kind of outrigger wall-connecting piece
Technical field
The utility model belongs to the realm of building construction, and in particular to a kind of outrigger wall-connecting piece.
Background technology
External scaffolding system refers to the scaffold set up in architecture enclosing, is mainly used in reinforced concrete construction, outer Wall is built by laying bricks or stones, alien invasion is fitted up.Wall-connecting piece is the important guarantee of scaffold stability, and JGJ130-2011 has accordingly to wall-connecting piece Regulation, but not specify wall-connecting piece concrete structure.
Existing outer scaffold wall connector has following three kinds of methods to be made:(1) pre-buried steel tube method:Before concreting, use One vertical short steel pipes are embedded in about 20cm in beam, expose beam and break an agreement 20cm, and concreting is complete, with level steel pipe long, vertical rod and Vertical short steel pipes fastener connection.(2) embedded iron parts method:Before main body beam column concrete construction, in the pre- buried strap anchor pin in relevant position Iron plate, after form removable, welded with steel pipe and the iron plate for exposing beam side or post side, the opposite side of steel pipe and the vertical rod of scaffold Connected with fastener.(3) method is anchored afterwards:In beam sides drilling, expansion anchor or chemical anchor bolts are installed, then with being welded into steel pipe in advance The anchor slab connection of one.
However, there are problems in existing outer scaffold wall connector, it is specific as follows:(1) pre-buried steel tube method:Pre-buried Steel pipe and part fastener cannot be recycled, and construction cost is high, while dismantling trouble, need to block hole, there is serious infiltration hidden danger, Gas cutting often is used during dismounting, is unfavorable for fire prevention, and reconcile limited up and down, influence retaining design construction.(2) embedded iron parts method:Steel plate And anchor pin cannot be reused, steel using amount is big, and construction cost is high, and construction procedure is complicated, to be welded during installation, will gas during dismounting Cut, it is cumbersome and have disaster hidden-trouble.(3) method is anchored afterwards:Construction trouble, only with 1 expansion anchor, bearing capacity is not high, easily Loosen, low cycle repetitive load can not be born, after the completion of construction, crab-bolt is scrapped, it is impossible to reused, and causes construction cost high.
Therefore, we can reuse in the urgent need to a kind of simple structure, easy to operate, reduce the outrigger of construction cost Wall-connecting piece.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple structure, easy to operate, can reuse, energy Reduce the outrigger wall-connecting piece of construction cost.
The technical scheme that the utility model is used is:A kind of outrigger wall-connecting piece, including it is embedded in the PVC through walls in wall Pipe, the interior steel plate washer with the first circular hole, outer steel plate washer and stud with the second circular hole;One end of stud passes through through walls The first circular hole of interior steel plate washer is then passed through after pvc pipe, is fixed finally by the first nut;The other end of stud passes through outer steel Fixed by the second nut after second circular hole of pad;One end of the outer steel plate washer and steel pipe is welded, the other end of steel pipe with The vertical rod fastener connection of scaffold, outer steel plate washer constitutes wall connecting rod part with steel-pipe welding;
The center line of the stud and the centerline parallel of steel pipe.
Construction procedure is:
The first circular hole (the first screwed hole) is first rushed in advance at the center of interior steel plate washer, is rushed second in advance on the top of outer steel plate washer and is justified Hole (the second screwed hole), one end of steel pipe is welded in the bottom of outer steel plate washer;
Before main column wall beam board member concrete construction, pvc pipe through walls is set in relevant position;
After the dismounting of concrete component vertical formwork, one end of stud is then passed through interior steel pad after passing through pvc pipe through walls First circular hole (the first screwed hole) of piece, fastens finally by the first nut;The other end of stud passes through outer steel plate washer Second circular hole (the second screwed hole) is fastened by the second nut afterwards;The other end of steel pipe is connected with the vertical rod fastener of scaffold;
After outer-wall building, alien invasion finishing are finished, by steel pipe, vertical rod fastener, interior steel plate washer, outer steel plate washer, the first spiral shell Mother, the second nut, stud are reclaimed totally, in case next time uses (turnover), have saved construction cost, economic ring again Protect;After cutting PVC sleeve pipes through walls, wall is repaired using cement mortar smooth, it is to avoid leak.Whole construction safety, efficiently, It is convenient.
Compared with prior art, the utility model has the advantage of:
After stud is passed through into pvc pipe through walls, its two ends is fastened by nut and steel plate washer, is welded on outer steel plate washer With the steel pipe of stud centerline parallel, structure is very simple, and during construction, only need to tighten nut can be installed, without Gas welding, electric welding, install very convenient, and only need to unclamp nut can just be dismantled, and dismounting is very convenient, time saving and energy saving;Make steel pipe Center line and double threaded screw centerline parallel, enhance the intensity of whole outrigger wall-connecting piece, improve resistance to overturning, bearing capacity Height, is integrally difficult to loosen;
After outer-wall building, alien invasion finishing are finished, can be by steel pipe, vertical rod fastener, interior steel plate washer, outer steel plate washer, first Nut, the second nut, stud are reclaimed totally, realize the recycling of device, have saved construction cost, economical and environmentally friendly;
Each steel pipe correspondence a piece stud and a pvc pipe through walls, stud two pieces of steel plate washers of correspondence With 2 nuts, structure is very simple, installs and dismantles and be also very convenient;A piece steel pipe piece pvc pipe through walls of correspondence, both subtracted Lack construction materials, saved construction cost, reduced the engineering time, also ensure that the intensity of wall;
The device for being used is conventional device, easy to make;
When embodiment is constructed, live fire operation is prevented effectively from, reduces fire safety evaluating hidden danger;Preformed hole is smaller, construction After the completion of only need to block pvc pipe, reduce hidden leakage defect;Construction is convenient, and workman's efficiency of construction is significantly improved.
