Abstract

The utility model discloses a scaffold wall connecting piece, which adopts the main structure: the tail end of a screw is provided with a screw thread and matched with two nuts, the screw is also sleeved with a steel base plate, the front end of the screw is welded on a broad plane of a steel channel, and a steel tube is welded on a narrow plane at one side of the steel channel. When in use, before placing concrete in a concrete structure, a UPVC tube is embedded in a beam form or a wall form as a prepared hole, a wall penetrating screw of the scaffold wall connecting piece penetrates through the UPVC tube from outside to inside, the scaffold wall connecting piece is fastened on the structural beam by the double nuts through the steel base plate, and meanwhile adjusting the use angle of the steel tube at the outer side of the scaffold wall connecting piece. The scaffold wall connecting piece is simple in structure and convenient in making, construction and use, and can be repeatedly used. The utility model is widely applied to scaffold body connection of high-rise building carrier beams and shear wall structural systems of various reinforcing steel bar concrete structures.

Description

Scaffold connecting spare

Technical field

The utility model relates to high-building construction and general framework, when external scaffolding is set up in the shear wall structure building operations, the effective rigidly connected special-purpose wall-connecting piece of scaffold and agent structure.

Background technology

Wall-connecting piece is the important component part of scaffold.The scaffold accident that collapses of collapsing takes place both at home and abroad, and a lot of cases all are because after wall-connecting piece is provided with improper or wall-connecting piece is removed, and in time do not mend to establish to cause.The unstability of scaffold is divided into whole unstability and local buckling usually.Wherein whole unstability is the main mode of failure of scaffold unstability.Destruction comes from and lacks wall-connecting piece lateral stiffness or the initial bigger transverse frame of camber.Be provided with rationally, bearing capacity is high, construct satisfactory wall-connecting piece, can both play direct effect, thereby the resistance to overturning of scaffold is played an important role the improvement of the effective span of computing unit, the raising of lateral stiffness.

At present, the domestic special-purpose wall-connecting piece that does not have integral body can have enough to meet the need use.The method that adopts mainly contains the stay bolt combined techniques, gives the steel pipe method of burying, crab-bolt fixation, banded column method now.The stay bolt combined techniques is to adopt to give to bury reinforcing bar with scaffold support body drawknot props up agent structure with the shelf steel pipe, and owing to this kind form poor stability, general highrise building scaffold building can not adopt.Give and bury steel pipe method cooperation banded column method, that adopts in highrise building at present is more.In frame structure building scaffold design process, adopt thick pillar hoop form wall-connecting piece at present earlier, meet post to embrace, floor height is greater than anchor ear twice on every concrete frame post of 4 meters.Even now, because span is big, when the wall-connecting piece designing and calculating can not satisfy regulation and stipulation, will give on Vierendeel girder and bury the shelf short steel pipes, and imbed 50cm length, expose 20cm length, the 50cm that imbeds is long finally can not to be taken out, and exposed parts also can not be removed owing to wall-connecting piece when building the space enclosing structure body of wall by laying bricks or stones, when doing the exterior decoration operation, it is also bigger to split out the loss quantity that causes fastener and steel pipe fully, has strengthened building costs.The banded column method is with 4 short steel pipes and 4 cruciform fastening for falsework tie to be lived after the frame column form removable, the method that is connected with support body by long steel pipe.Crab-bolt anchoring method is the connection steel pipe of burn-oning again of anchor plate on the concrete structure with expansion anchor or chemical anchor bolts.This method cost height, bearing capacity is but not high, and crab-bolt can not repeat turnover and use.Develop a kind of rational in infrastructurely, the scaffold connecting spare that satisfies highrise building scaffold and agent structure connection request is necessary.

The utility model content

The technical problems to be solved in the utility model provides a kind of scaffold connecting spare, and this scaffold connecting spare is used for the high-building construction scaffold and major structure of construction is rigidly connected.This scaffold connecting part is in engineering practice, that building structure can not be satisfied is pre-buried, develop under the condition of anchor ear post, its special-purpose applicability is strong, can integral body repeat the turnover use, and its rigidity all can satisfy the requirement that the highrise building scaffold is connected with agent structure with bearing capacity.

The technical problems to be solved in the utility model is realized by following scheme: scaffold connecting spare, comprise screw rod, steel pipe, it is characterized in that: described screw rod is not held and is had screw thread, and cooperate with two nuts, screw rod also overlaps a billet, the front end of screw rod is welded on the wide plane of a channel-section steel, steel pipe of welding on the side narrow plane of channel-section steel.

The utility model also comprises following scheme: described screw rod is vertical with described steel pipe.

Advantage of the present utility model is: during use, before the concrete structure is built concrete, requirement according to scaffold safe construction scheme, position at design scaffold connecting spare, give in beam forms or in the wall form and bury a UPVC pipe, box out as giving of scaffold connecting spare screw rod through walls, scaffold connecting spare screw rod through walls is passed the UPVC pipe from outside to inside, scaffold connecting spare is fastened on the structural beams (or wall) by billet with double nut, adjusts the use angle of scaffold connecting spare outside short steel pipes simultaneously.The ordinary circumstance level is used, and special circumstances can vertically or be selected suitable fixed angle for use.With the little cross bar steel pipe of the scaffold host node that is connected with the scaffold support body, prop up the fastener fastening of beam concrete, the fastening other end is connected with scaffold support body vertical rod fastener, has promptly finished the connection operation, and is very easy.If be used for the building operations of high residential building shear wall structure, template adopts the large formwork construction method, and formwork reinforcement can utilize with the through-wall bolt hole, can do no longer in addition to give and box out.

This scaffold connecting part simple in structure safe, make and construct easy to usely, applicability is strong, can repeat turnover and use.Specialty user praise is very high, can be widely used in the highrise building Vierendeel girder of various reinforced concrete structures, the scaffold support body connection of shear wall structure system.Especially large formwork construction technology shear wall structure utilizes large form to reinforce bolt hole, substitutes as preformed hole, more can highlight the advantage that scaffold connecting spare is compared with conventional practice.
