Description

High altitude scaffold for building builds connecting piece

Technical Field

The invention relates to a high-altitude scaffold building connecting piece for buildings.

Background

When carrying out high altitude scaffold and putting up, at first need rely on the building to put up the many scaffold steel pipes of vertically arranging, then put up horizontal scaffold steel pipe again, when putting up horizontal scaffold steel pipe, it needs the climbing on the fore-and-aft scaffold steel pipe of completion to put up the personnel, because the steel pipe extends to the outside of the building body, consequently can take place great shake, the installation is comparatively inconvenient, and need wear the safety rope, even wear the safety rope, it is also comparatively unsafe to erect at the high altitude.

Based on the problems, the high-altitude scaffold for the building is easy to build and does not need to climb and install.

Disclosure of Invention

The invention aims to solve the technical problem of providing a building high-altitude scaffold building connector which is easy to build a high-altitude scaffold and does not need to climb and install.

In order to solve the problems, the invention adopts the following technical scheme:

a high altitude scaffold for building puts up connecting piece, includes two square clamps that are the longitudinal symmetry setting, the left and right sides department of square clamp has processed the otic placode, two from top to bottom between the square clamp through the otic placode cooperation has the bolt, at every the inboard of square clamp all is provided with a pivot, the lateral wall department of square clamp has processed the cooperation assembly the pilot hole that the pivot was used, the pilot hole is the shoulder hole the cooperation has the bearing between the diversion hole and the pivot, and the bearing is installed in the macropore position department of pilot hole, be provided with first pilot hole in the preceding terminal surface department of square clamp, first pilot hole also is the shoulder hole, be provided with the fabrication hole that corresponds first pilot hole in the rear end face department of square clamp, the macropore of first pilot hole is close to the pilot hole, install a slider in the macropore of first pilot hole, the front end of the sliding block is in threaded connection with a pull rod, one end, far away from the sliding block, of the pull rod is located on the outer side of the square clamp, a large end portion is machined at the end, a pull ring is assembled through the large end portion, a spring is assembled on the pull rod, the spring acts between the sliding block and the stepped surface of the first assembling hole, positioning gear shaping is arranged at one end, far away from the pull rod, of the sliding block, a plurality of tooth grooves matched with the positioning gear shaping are annularly arranged on the rotating shaft, when the positioning gear shaping is inserted into the tooth grooves, the rotating shaft is locked, and otherwise, the rotating shaft is unlocked; the rotating shaft is sleeved with a positioning pipe made of rubber, an annular groove is formed in the outer wall of the positioning pipe, and a clamping opening for clamping a scaffold steel pipe is formed between the upper positioning pipe and the lower positioning pipe through the combination of the annular groove; the end face of the square hoop is provided with a through hole, the outer side of the square hoop is provided with a circular hoop, the circular hoop is composed of two parts, a first bolt is connected between the two parts, a rod piece is arranged outside the circular hoop, and the rod piece is matched with a nut after penetrating through the through hole; the rod piece is sleeved with a gasket, and the gasket is in contact with the square hoop.

Preferably, a plurality of anti-slip ribs are injected and molded in the annular groove, an arc-shaped notch groove is formed outside the anti-slip ribs by injection molding, when the upper square hoop and the lower square hoop are tightened, the anti-slip ribs are attached to the scaffold steel pipe after being deformed, and the rotation resistance of the rotating shaft is increased; above-mentioned structure, deformation through the antiskid muscle can increase and scaffold steel pipe between the frictional resistance, at this moment, horizontal scaffold steel pipe only when receiving great dynamics, just can make the registration arm rotate, at this moment, even the connection of location gear shaping and tooth's socket is lost efficacy, also can remain stable.

Preferably, a locking screw is screwed in the outer part of the circular hoop, the lower end of the locking screw is processed to form a ball head, and a plurality of stress holes radially penetrate through the outer wall of the locking screw at the position close to the upper end; inserting blocks are assembled at the positions of the two scaffold steel pipes butted in the circular hoop, the diameter of each inserting block is larger than the inner diameter of each scaffold steel pipe, each inserting block is provided with an inserting pipe part, each inserting pipe part is inserted into each scaffold steel pipe and is in transition fit with each scaffold steel pipe, each inserting block is provided with an outer conical surface, the ball head acts on the outer conical surface, when the locking screw is screwed down, the inserting blocks on the two sides are pushed away, and at the moment, the fit resistance between each inserting block and each scaffold steel pipe is increased; in the conventional art, two adjacent horizontal scaffold steel pipes need to be installed in a staggered mode, and during installation in a staggered mode, the two scaffold steel pipes need to be provided with four connecting pieces, each scaffold steel pipe needs to be installed independently, and installation is very troublesome. After the structure is adopted, two adjacent scaffold steel pipes can share one connecting piece, and the two adjacent transverse scaffold steel pipes do not need to be installed in a staggered mode; the installation time is shorter, and the installation is more convenient.

The installation mode of the product is as follows:

firstly, installing a plurality of longitudinal steel pipes in a conventional installation mode near a building position, then sequentially installing an upper square hoop and a lower square hoop at the tail end (the tail end is close to one end of a building body) of each steel pipe, after the upper square hoop and the lower square hoop are fixed, ensuring that no gap exists between the steel pipe and a clamping opening and certain moving resistance exists, then assembling the transverse steel pipes in the circular hoops, and screwing a first bolt to clamp the steel pipes by the circular hoops; after the completion, adopt a nylon rope, the constraint is on the pull ring, prepare a purpose-made push rod again, the push rod has the mouth that agrees with the steel pipe, keep the tightness of nylon rope, then promote the push rod, the push rod promotes the steel pipe and moves to the outside, and the nylon rope pulls open the pull rod, break away from between location inserted tooth and the tooth's socket this moment, the pivot is rotatable, can outwards release horizontal steel pipe, after promoting to the assigned position, relax the nylon rope, the pull rod kick-backs, the location inserted tooth inserts in the tooth's socket, the pivot locking this moment, because the outside of pivot is the registration arm through rubber materials, rely on the deformation of registration arm, make and keep fixed between the vertical steel pipe of square clamp and below. After the operation is finished, the push rod is continuously used for pushing the transverse steel pipe, and whether the steel pipe is fixed stably or not is determined.

The product is dismantled as follows:

when the scaffold is required to be disassembled, only the nylon rope needs to be pulled, the positioning gear shaping is separated from the tooth groove after the nylon rope is pulled, and the device can be directly pulled after the nylon rope is pulled.

The invention has the beneficial effects that: this product is particularly suitable for the high altitude to erect, has adopted this product back, and the work of whole high altitude erection scaffold can be accomplished on the building body, need not the climbing, installs more safety, and also more convenient also does benefit to the later stage equally and demolishs, and the structure of this product is comparatively simple, and the cost is comparatively cheap, is fit for using widely.
