Description
Technical field
The utility model relates to the structure that scaffold is built the wall-connecting piece of usefulness in the building engineering construction, belongs to the architectural engineering construction technique field.
Background technology
In the building operations, during as the whitewashing or decorate of agent structure or exterior wall, need scaffold erecting from the certain distance of exterior wall, scaffold must couple together with body of wall.General steel pipe building scaffold adopts common steel tube or ironware to be embedded in the concrete structure usually, pre-buried steel pipe, the ironware of steel tube fastener formula wall-connecting piece is disposable use, expense is higher, and this kind wall-connecting piece calculates working strength and is controlled by the fastener skid resistance, generally be no more than 8KN, even use two fasteners also only to calculate usually according to 12KN.Pre-buried steel pipe, ironware with after just scrapped, must could remove with gas cutting during dismounting, and metope also easily produces rust staining.
The utility model content
The purpose of this utility model is exactly at the existing technology above shortcomings that scaffold erecting, and a kind of building scaffold wall-connecting piece safe, high-strength, economic, rigidity easily and efficiently of the usefulness that is used to scaffold erecting is provided.
The purpose of this utility model is to realize like this, the building scaffold wall-connecting piece, it is characterized in that being provided with hemispherical sleeve, bulb (beam) through walls screw rod and connect the wall steel pipe, the hemispherical bush whorl is connected an end of wall steel pipe, the sphere end of hemispherical sleeve is provided with aperture, bulb (beam) through walls screw rod passes aperture, and bulb places in the hemispherical sleeve; Connect the wall steel pipe and be provided with the device for positioning and securing that is made of slide block, fastening bolt and pad, the tube wall that connects the wall steel pipe is provided with row's bolt hole, and device for positioning and securing is fastened on the wall steel pipe by fastening bolt and bolt hole.
The medial surface of described slide block is and the face of cylinder that connects wall outer wall of steel pipe coupling that the middle part of slide block is provided with the perforation of fastening bolt.
The one side that described pad contacts with fastening bolt is the plane, is the face of cylinder with connecting the one side that wall steel pipe inwall contacts.
The utility model is simple and reasonable, manufactures easily, and cost is low, and is easy to use.During use, itself and the standard fastener that being connected of scaffold uses the job site generally to use are connected (beam) the through walls bolt hole that stays in the time of can utilizing formwork erection with concrete structure, do not have consumptive material.Do not use (beam) through walls bolt as concrete frame structure exterior wall (beam), embedding one section 20mmPUC plastic pipe that equals wall thickness (deck-siding) in scaffold relevant position wall (beam) in advance, no material consumption or consumptive material expense are minimum.

Among the figure: 1 connects wall steel pipe, 2 hemispherical sleeves, 3 bulbs (beam) through walls screw rod, 4 slide blocks, 5 fastening bolts, 6 pads, 7 bolts hole, 8 bulbs.
The specific embodiment
2 mouthfuls of ends of hemispherical sleeve are provided with internal thread, and the sphere end of hemispherical sleeve is provided with aperture.Bulb screw rod through walls (or bulb is worn the beam screw rod) 3 is a bulb for an end of screw rod, and the other end of screw rod has the attaching nut of coupling, and the screw rod of bulb screw rod through walls passes the aperture of hemispherical sleeve sphere end, and bulb 8 places in the hemispherical sleeve.Connect wall steel pipe 1 and adopt Φ 48 steel pipes, even be connected and fixed with hemispherical sleeve-port end internal thread after the wall steel pipe one end machining screw, screw strength satisfies the tensile strength of steel pipe.
The hemispherical sleeve contacts with concrete wall or beam, because contact point is a sphere, certain bidimensional degree of freedom is arranged.When the line (face) of scaffolding steel pipe vertical rod and wall-connecting piece bolt hole during, there is certain horizontal degree of freedom to guarantee to connect the wall steel pipe and easily reliably is connected with scaffold with wall (beam) face out of plumb.Code requirement connects the wall steel pipe and answers level or sagging setting, and accurately adjustment is to meeting the demands for sphere contact, and the fastener that wall connecting rod is connected with scaffold is subjected to torsion.Bulb screw rod through walls and hemispherical sleeve are used, and intensity is reliable, and penetrating preformed hole can be fastened on the wall (beam) connecting the wall steel pipe easily, satisfies rigidly connected requirement.
Connect the device for positioning and securing of establishing row's bolt hole 7 and constituting on the tube wall of wall steel pipe 1 by slide block 4, fastening bolt 5 and pad 6.The medial surface of slide block 4 is and the face of cylinder that connects wall outer wall of steel pipe coupling that the groove that passes for fastening bolt is established at the middle part of slide block.The one side of pad 6 is planes, for the contact surface of fastening bolt, pad 6 is the face of cylinder with connecting the one side that wall steel pipe 1 inwall contacts.Slide block 4 is fastened on the wall steel pipe 1 by fastening bolt 5 and pad 6.Device for positioning and securing is fastened on the wall steel pipe by fastening bolt and bolt hole.
Slide block is a cylinder with connecting wall steel pipe contact portion, closely contacts with steel pipe, and when tightening fixing bolt, slide block can be along with bolt rotate, and tightening between back and the steel pipe has uniform pressure and frictional force.Fastening bolt is a standard component, when highrise building scaffold wind load is big, can selects the frictional force of other bolt of different intensity scale with raising slide block and steel pipe, thereby satisfy wall-connecting piece intensity calculation requirement.
The one side that pad contacts with fastening bolt is the plane, and the one side that contacts with steel pipe is the cylinder of combining closely with steel pipe internal-surface, after fastening bolt is tightened, can produce uniform frictional force on pad and steel pipe contact surface.
Φ 48 connects the wall steel pipe and can process with the common scaffolding steel pipe of 3.5mm wall thickness.Screw thread is connected with spherical sleeve, and hole across a certain distance and bolt slide block are used above, can satisfy to clamp scaffold at any position and connect the fastener that the wall steel pipe is connected, and leaves the different spacing requirement of structure outer face to satisfy scaffold.
