Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and more specifically, it relates to an external scaffolding structure with high and low spans. Background Technology

[0002] In construction, when building external protective scaffolding on the roof of a basement, if the floor height is high, the column spacing is large, and the columns of the first floor have not yet been poured with concrete, the external protective scaffolding will lack reliable tie points. This will seriously affect the overall stability of the scaffolding, increase the risk of overturning or deformation, and may lead to safety accidents such as falls from heights and collapses. In addition, the lack of tie points will also reduce the scaffolding's wind load and lateral load resistance, making construction workers face greater safety hazards when working on the scaffolding. It may also affect the smooth progress of subsequent construction procedures and even delay the construction period. If effective temporary reinforcement measures are not taken, it may also lead to uneven stress on the scaffolding, exacerbating the risk of loose fasteners or bending of members, further threatening construction safety. Therefore, it is necessary to plan a reasonable temporary support or tie scheme in advance to ensure the stability of the external protective scaffolding and construction safety. Utility Model Content

[0003] This disclosure relates to an external scaffolding tie structure for high and low spans, in order to solve the problem mentioned in the background art where, when constructing external protective scaffolding on the top slab of a local warehouse, if there are situations where the floor height is high, the column spacing is large, and the columns of the first floor have not yet been poured with concrete, the external protective scaffolding will lack reliable tie points, which will seriously affect the overall stability of the scaffolding, increase the risk of the scaffolding overturning or deforming, and may cause safety accidents such as falls from heights and collapses.

[0004] This utility model discloses an external scaffolding structure for high and low spans, achieved through the following specific technical means:

[0005] This utility model provides an external scaffolding structure with varying heights and spans, comprising: two steel pipes, with a fixing fastener fixed between the two steel pipes; the steel pipes also include: a water-stop screw rod, which is fixedly installed in the middle of the steel pipe.

[0006] As a preferred embodiment of this utility model, the fixing fastener is provided in two parts, and the two fixing fasteners are rotatably connected; the fixing fastener further includes a connecting member, which is arc-shaped and rotates to one side of the bottom of the fixing fastener.

[0007] As a preferred embodiment of this utility model, the fixing fastener further includes: a fixing connector, which has a rectangular head structure and two fixing connectors are provided. The fixing connectors are symmetrically and integrally disposed on the top of the fixing fastener and the top of the connector; and fixing screws, which are engaged and fixedly installed between the fixing connectors.

[0008] As a preferred embodiment of this utility model, the fixing fastener further includes: a reinforcing block, the reinforcing block being arc-shaped, and the number of reinforcing blocks being set to two sets, the reinforcing blocks being symmetrically fixedly installed on both sides of the fixing fastener and both sides of the connector.

[0009] As a preferred embodiment of this utility model, the fixing fastener further includes: a reinforcing slider, which is rectangular in shape and slides inside the reinforcing block; and a reinforcing side block, which is circular in shape and integrally disposed in the middle of one side of the reinforcing slider.

[0010] As a preferred embodiment of this utility model, the fixing fastener further includes: a transmission screw, which rotates inside the reinforcing block; and a threaded connection between the transmission screw and the reinforcing slider.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] When fixing the fasteners to the steel pipes and tie rods, the tightening effect can be adjusted by rotating the transmission screw. Since the transmission screw and the reinforcing slider are connected by threads, rotation will drive the reinforcing slider to move axially, making it tightly press against the contact surface of the steel pipe and tie rod, thereby applying a uniform and stable compressive force and effectively enhancing the rigidity of the connection node. This design not only significantly improves the connection stability between the fasteners and the steel pipes and tie rods, reducing the risk of loosening due to vibration or load changes, but also ensures more uniform force distribution, avoids local stress concentration, and thus extends the service life of the fasteners. At the same time, the progressive tightening method of the reinforcing slider makes installation and adjustment more convenient. Construction personnel can flexibly adjust the tightening force according to actual needs, which not only ensures construction efficiency but also improves the safety and reliability of the overall structure. It is especially suitable for temporary structures such as scaffolding and support frames under high load or dynamic load conditions, ensuring that they can maintain stable connection performance under complex working conditions.
