Description

Technical Field

[0001] The utility model relates to the technical field of scaffolding, and more particularly to an adjustable connection device for a buckle scaffolding. Background Art

[0002] Socket-and-spigot scaffolding is a new type of in-line, self-locking steel pipe scaffolding. Compared to traditional coupler-type steel pipe scaffolding, it significantly improves erection and dismantling efficiency, reliability, safety, cost savings, and energy conservation and environmental protection, making it widely used in engineering construction. Coupler-type scaffolding is a fixed component secured with latches, making the frame more rigid than fastener connections. The coupler supports are centered, while the eccentric load-bearing of coupler-type scaffolding significantly improves stability, safety, and reliability.

[0003] Common specifications for horizontal bars in scaffolding with interlocking scaffolding are 300, 600, 900, 1200, and 1500 mm, but due to the influence of the structural span, transition spans with non-standard spacing often exist. When erecting a full-span support frame, the support frame uprights are preferentially arranged at the bottom of the beam (with the beam centered). The adjustment span transition section is set in the mid-span area of the slab with less load. Fastener-type steel pipe crossbars are often used for transition. The fastener-type steel pipe is connected to the interlocking scaffolding uprights with fasteners and needs to extend one span to connect two interlocking uprights. Due to the performance mismatch between the primary and secondary keels and the coil scaffolding, only the conventional vertical pole spacing of 900×900mm can be used. If the spacing is expanded, the primary and secondary keels such as channel steel and square tubes need to be replaced or light scaffolding needs to be installed. However, the cost is high and the one-time capital investment is large, so it cannot be promoted on a large scale. In addition to super-high frames, most companies basically use wheel-type or steel pipe scaffolding. Due to the different vertical pole spacing between high-space coil scaffolding and peripheral scaffolding, steel pipe frames are often used for transition.

[0004] Due to different functions, the base of the buckle scaffolding often has high and low spans when it is erected. Adjustable base supports and short joint vertical poles are used for connection, but it is still impossible to achieve the high and low span buckle connection plates on the same plane.

[0005] In order to improve the overall stability of the buckle scaffolding and meet the needs of non-standard spacing transition spans, different types of frame connections, and high and low span frame connections, it is imperative to develop a rod that can be adjusted up and down, the horizontal rod length can be adjusted, and the horizontal rod can be rotated. Utility Model Content

[0006] To overcome the shortcomings of the prior art, the present invention provides an adjustable connection device for scaffolding with a truss. This connection device can be used to reinforce vertical poles at different spacings, expanding its applicability and accommodating connections between scaffolds of different types and angles. This effectively addresses the shortcomings of the prior art and replaces the traditional method of connecting with steel pipes, offering greater convenience, practicality, and reduced material investment.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0008] Disclosed is an adjustable connection device for a disc-type scaffolding, which is connected to the disc-type scaffolding and includes a steel pipe upright, a steel pipe horizontal rod, a three-section telescopic rod, a groove-type connection assembly and a galvanized connection fastener assembly. The groove-type connection assembly and the galvanized connection fastener assembly are respectively arranged at both ends of the three-section telescopic rod. The three-section telescopic rod is connected to the upright of the disc-type scaffolding through the groove-type connection assembly. The three-section telescopic rod is connected to the steel pipe upright through the galvanized connection fastener assembly. The steel pipe horizontal rod is arranged between the steel pipe uprights.

[0009] The three-section telescopic rod includes a first hollow screw, a second hollow screw and a connecting sleeve. The connecting sleeve is provided with an internal thread. The first hollow screw and the second hollow screw are respectively threadedly connected to both sides of the connecting sleeve.

[0010] The groove-type connection assembly is arranged on the vertical pole of the disc-type scaffolding, and a connecting vertical plate is provided at the end of the first hollow screw away from the connecting sleeve. A pair of connecting clamps are arranged in parallel on the connecting vertical plate, and the connecting clamps are connected to the groove-type connection assembly through a first fastening bolt.

[0011] The groove-type connection assembly includes two groups of symmetrically arranged arc-shaped clamps, and the two arc-shaped clamps are clamped on the vertical poles of the disc buckle scaffolding. The arc-shaped clamps include a groove-type semicircular ring clamp and an arc-shaped sleeve. The arc-shaped sleeve is welded and arranged below the groove-type semicircular ring clamp. The arc-shaped sleeves on the two arc-shaped clamps are connected by sleeve connecting bolts. The groove-type semicircular ring clamp is provided with a slot, and the spacing between the two connecting splints is matched with the thickness of the groove-type semicircular ring clamp. The first fastening bolt passes through the slot.

[0012] The galvanized connecting fastener assembly is arranged on the steel pipe vertical pole, and the Y-shaped connecting frame is provided at the end of the second hollow screw away from the connecting sleeve. The second hollow screw is connected to the galvanized connecting fastener assembly through the Y-shaped connecting frame.

[0013] The galvanized connecting fastener assembly includes a fastener straight plate, an arc-shaped fastener and an L-shaped plate. One end of the arc-shaped fastener is hinged to one end of the fastener straight plate, and the other end of the arc-shaped fastener is connected to the fastener straight plate through a second fastening bolt. The L-shaped plate is arranged below the fastener straight plate. A connecting screw is provided at the bottom of the L-shaped plate, and a positioning screw is provided on the side of the L-shaped plate. The Y-shaped connecting frame is connected to the L-shaped plate through the connecting screw and the positioning screw.

[0014] The Y-shaped connecting frame includes a transverse connecting plate and a U-shaped frame. The transverse connecting plate is fixedly connected to the second hollow screw. The U-shaped frame is arranged at one end of the transverse connecting plate away from the second hollow screw. Holes corresponding to the positioning screw are formed on the transverse connecting plate, and holes corresponding to the connecting screw are formed on the U-shaped frame.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] This structure is simple and easy to operate. By setting an adjustable mechanism, directly rotating the connecting sleeve can lengthen or shorten the connecting rod until it is adjusted to the appropriate length. A connecting piece is arranged at the end to connect with the disc buckle scaffold or the vertical rod of other types of scaffolds. The three-section telescopic rod is effectively connected through a grooved connecting component and a galvanized connecting fastener component to fix the three-section telescopic rod. The three-section telescopic rod can be applied to the reinforcement of vertical rods with different spacings, improving the scope of application. The grooved connecting component arranged on the vertical rod of the disc buckle scaffold can move up and down, meeting the connection between the frame bodies with different base elevations at the construction site. There is no need to separately configure short vertical rods for adjustment, which can improve the overall stability of the frame body. Moreover, the grooved connecting component can rotate arbitrarily by 180 degrees, meeting the connection between frame bodies of different types and different angles, and can well solve the deficiencies of the prior art. It is more convenient and practical to replace the traditional method of using steel pipes for connection in the past, reducing the material input. BRIEF DESCRIPTION OF THE DRAWINGS
