Problems solved by technology

For example, Chinese invention patent application CN1916289A discloses a diamond-shaped hanging basket, the main truss adopts a diamond-shaped structure, and the two main trusses are connected as a whole by connecting the upper frame, the lower frame, the front frame and the rear frame, and the lower part of the main truss is provided with Two running mechanisms, including a suspension mechanism and an anchoring device, this kind of hanging basket can better solve the current domestic high-speed railway construction. The continuous bridge with a single width within 13m is a single-box single-chamber structure. However, according to the current needs of line construction, there are continuous girder bridges for four-line railways in the design of high-speed railway construction. The width of the bridge reaches nearly 23m. Symmetrical two-way overall synchronous pouring construction is required, and it cannot solve the pouring problem of this type of continuous beam well

Embodiment 1

[0023] Example 1 (casting beam type a)

[0024] Refer to attached figure 1 , figure 2 , the present embodiment includes a main truss 5, the main truss 5 is roughly in a rhombus structure, two short nodes are connected by vertical beams, and one of the rhomboid sides is placed horizontally on the continuous beam 30; The upper beam 1, the scissor brace 6 connected by the front upper slope, the vertical truss 4 connected by the middle part, and the transverse rod 7 connected by the rear upper slope form a whole, and are placed symmetrically at the two ends of the continuous beam 30 in the front and rear pouring directions; The main trusses 5 are arranged in four trusses, and each truss is provided with a corresponding running mechanism.

[0025] Refer to attached figure 1 , Figure 4 and Figure 5 . The guide slide beam device comprises a middle guide slide beam device arranged at the middle section position of the continuous beam 30 section and a side guide slide beam dev...

Embodiment 2

[0031] Embodiment 2 (casting beam type b)

[0032] Refer to attached figure 1 , image 3 , Figure 6 , Figure 7 . Compared with Embodiment 1, the difference is that the continuous beam body cancels the middle cavity, and is a single-box double-chamber structure. The main truss 5 is set as three trusses, and the chain block 33 and the two sets of guide sliding beam mechanisms 16 set on the upper part are cancelled. , the horizontal width of the hanging basket remains unchanged, and the other structures are the same as in Embodiment 1.

[0033] During work, the continuous beam 30 adopts two-way symmetrical pouring, wherein the bottom basket system 10 transmits the load to the front upper beam 1 of the main truss 5 through the suspenders 20, 21, and then to the front support node 2 of the main truss 5. The truss 5 transfers the load to the continuous beam 30 through the rear anchor rod, that is, the front support node 2 is subjected to compressive load, and the rear support...

Abstract

The invention relates to a cantilever-concreting construction hanging basket for a four-lane and wide-width continuous beam of a high-speed rail. In the cantilever-concreting construction hanging basket, main trusses are connected into a whole by a front upper beam connected to the front upper end part, a herringbone strut connected to a front upper slope, a vertical truss connected to the middle part and a transverse rod connected to an upper slope of the rear part and are arranged on two end parts of the continuous beam in the front and rear pouring direction symmetrically; at least three main trusses are arranged, and each truss is provided with a corresponding travelling mechanism; a reinforced truss is arranged on the lower part of a bottom basket; and the cantilever-concreting construction hanging basket also comprises a plurality of groups of middle oriented sliding beam devices and side oriented sliding beam devices, and operating platforms are arranged on the rear parts of the side oriented sliding beam devices. The cantilever-concreting construction hanging basket is high in stability, and can perform symmetrical two-way integral synchronous pouring construction, so the problem of the pouring of wide-width continuous beams with single boxes and double rooms or multiple boxes and rooms in the construction of the high-speed rails at present is solved effectively.

Description

technical field [0001] The invention relates to construction equipment for suspended grouting of bridge continuous beams, in particular to a hanging basket for suspended grouting construction of four-line wide continuous beams of high-speed railways. Background technique [0002] The hanging basket is an important equipment for the construction of beams on large-span railways and highways using cantilever pouring. When using the hanging basket to build a long-span bridge, it will not be affected by environmental factors such as the height of the pier and the depth of the river, and the construction will be extended from the poured pier section by section to the span direction. This pouring construction technology not only simplifies the construction difficulty of long-span bridges, but also can greatly save the construction period and cost of erecting full-span supports, etc., so it is often used in bridge design and construction. [0003] But the existing continuous beam s...
