Problems solved by technology

Because it is not only difficult to open holes on the web of the box girder, but also damages the main structure. At the same time, the high-altitude construction operation outside the web of the steel box girder is very dangerous. Therefore, how to fix the tripod, how to reduce or avoid the high-altitude outside the steel box girder How to reduce the self-weight of the tripod structure and facilitate installation becomes the key to the problem

Embodiment Construction

[0024] Such as figure 1 As shown, the single-point fixed adjustable cantilever tripod according to an embodiment of the present invention belongs to a construction temporary support structure, including horizontal bars 1, vertical bars 2, oblique bars 3, web bars 4, connecting plates 5, and stiffeners 6( Image 6 ), baffle plate 7, adjustable bearing 8, rotating bearing 9 and guardrail 10. Among them, horizontal bar 1, vertical bar 2, inclined bar 3, web bar 4, connecting plate 5, stiffener 6, and baffle plate 7 constitute the main structure of the cantilevered tripod, which bears the weight of the newly poured concrete and the load during construction The adjustable support 8 and the rotating support 9 are supports for fixing or supporting the tripod and adjusting the angle of the tripod; the guardrail 10 is used for edge protection during construction to ensure construction safety.

[0025] Such as figure 2 As shown, the adjustable support 8 includes a screw rod 17 and a...

Abstract

The invention provides a single-point fixing adjustable cantilever tripod. The tripod comprises a horizontal rod (1), a vertical rod (2) and an oblique rod (3), which are connected to be triangular, as well as a rotary support base (9) and an adjustable support base (8); the rotary support base (9) is connected to one end part, close to the vertical rod (2), of the horizontal rod (1), so the tripod is connected to the outside in a mode of rotating in a vertical plane; the adjustable support base (8) is connected with one end part, far away from the horizontal rod (1), of the vertical rod (2) for supporting the tripod. The single-point fixing adjustable cantilever tripod is fixed by means of a well erected steel box girder, a support does not need to be erected from the ground, and the adjusting on angles or slopes needed by engineering can be met.

Description

technical field [0001] The invention relates to a single-point fixed and adjustable cantilevered tripod, which is suitable for the fields of highway bridge and house construction, and is especially suitable for the construction of steel-concrete composite beam wing plates. Background technique [0002] With the continuous improvement and development of my country's highway and railway transportation infrastructure, the number of new bridges that cities need to build continues to increase, and the number of road bridges that need to be built across valleys and rivers in mountainous areas continues to increase, which puts forward higher requirements for bridge construction technology. Steel-concrete composite beams have achieved rapid development due to the advantages of steel beams being convenient for factory processing, high structural bearing capacity and light weight. In order to reduce the overall steel consumption, the main body of the box girder adopts a steel structur...
