Description

Telescopic scaffold frame is striden in variable

Technical Field

The utility model belongs to the technical field of the scaffold frame, especially, relate to a variable telescopic scaffold frame of striding.

Background

The scaffold is used as an important pedal and temporary support, and various constructions can not leave the assistance of the scaffold. With the rapid rise of infrastructure construction, especially the construction of the main structure of the subway deep foundation pit is more inseparable from a scaffold. However, due to the limitation of the width of the foundation pit, the arrangement of the scaffold in the foundation pit is very limited, and the construction erection and the safety are seriously influenced.

Most of scaffolds in the current market are that the modulus of a horizontal rod is a multiple of 30cm, and the requirement of any telescopic size cannot be met, so that the practical requirement of limited erection of the scaffold for subway construction is difficult to meet. Secondly, the horizontal rods of the scaffold are mostly circular, bolt holes are difficult to align during insertion, and need to rotate ceaselessly, and the construction speed is greatly reduced due to the uncertainty of socket positions in the process of erection.

Therefore, the utility model provides a can not receive the use of topography restriction, stretch out and draw back the length of scaffold frame horizontal pole and satisfy the variable telescopic scaffold of striding of different demands.

SUMMERY OF THE UTILITY MODEL

To the problem that prior art exists, the utility model provides a variable telescopic scaffold frame of striding.

The utility model is realized in such a way that,

the utility model provides a variable telescopic scaffold of striding, includes scaffold pole setting, scaffold horizontal pole, the joint portion at scaffold horizontal pole both ends clamps on the tray that holds of scaffold pole setting, its characterized in that: the scaffold cross rod adopts a telescopic structure and comprises two scaffold upright rod connecting sections with the same structure and an adjusting rod, wherein each scaffold upright rod connecting section is of a hollow structure and comprises a clamping connecting part and a socket part, the socket part is of a square structure, and a plurality of through first pin holes are vertically formed in the length direction of the vertical face of the socket part; the cross section of the adjusting rod is consistent with that of the socket part, and a second pin hole is formed in the adjusting rod along the length direction; one end of the adjusting rod is inserted into a socket part of one scaffold upright rod connecting section, the other end of the adjusting rod is inserted into a socket part of the other scaffold upright rod connecting section to form a scaffold cross rod, and a pre-tightening pin is inserted into the first pin hole and the second pin hole.

Preferably, the pre-tightening pin is a wedge pin.

Preferably, the scaffold upright rod connecting section is of a clamping connecting part and socket part integrated stamping structure or a welding structure.

Preferably, the cross section of the clamping connection part is circular or square.

The utility model has the advantages and technological effect: the utility model discloses scaffold frame horizontal pole adopts above-mentioned technique for this kind of structure can not receive the use of topography restriction, stretches out and draws back the demand that satisfies the difference to scaffold frame horizontal pole length at will. Meanwhile, the socket part of the cross rod of the scaffold adopts a square structural form, so that the square adjusting rod can be inserted into the pin hole conveniently and the pin hole can be centered. Meanwhile, the positions of the pin holes are changed from up and down to be centered front and back, so that the construction operation is convenient; the socket position of the scaffold erecting process is relatively fixed, and the safety of equipment is improved.
