Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to an inner formwork operating platform for a hollow pier. Background Art

[0002] As railway construction continues to strengthen, bridges, as one of its important components, have gradually become the focus of railway construction in various places. In the construction process of bridges, piers are a vital part, and their load-bearing capacity directly affects the stability and service life of the bridge. Hollow piers are one of the pier types widely used in recent years. They reduce the amount of concrete required for construction, improve construction efficiency, and also save costs.

[0003] Variable-section high bridge piers are one of the most common types of piers in mountain highways and railway bridges. For the inner formwork construction of variable-section hollow piers, the traditional practice is to pre-embed climbing cones when pouring concrete. After the concrete reaches a certain strength, the platform body is installed on the climbing cones. However, in the actual construction process, there are some problems in using climbing cones to install the platform body: multiple sets of climbing cones are required to meet the construction requirements, which is costly; disassembly and assembly are difficult; and the concrete needs to be repaired after the climbing cones are removed, which affects the appearance quality of the concrete.

The horizontal plate 12 extends from the vertical plate 11 into the hollow pier, and the horizontal plate 12 is provided with a threaded hole. There are multiple fine-rolled threaded steel bars 3. The upper end of the fine-rolled threaded steel bars 3 passes through the threaded hole and is threadedly connected to the horizontal plate 12. The lower end is installed with a hanger 6 (such as Figure 1 and Figure 3 As shown). There are multiple first sleeves 4, each of which is located at the top of each threaded hole and is threadedly connected to the finished rolled threaded steel bar 3. Figure 1 , Figure 3 and Figure 4 As shown, the platform body 7 is connected to the bottom of each sling 6 .

[0043] like Figure 5 As shown, in this embodiment, the number of the corbels 1 is 8, among which 4 corbels 1 are symmetrically located on the straight line segment of the inner mold 2, and 4 corbels 1 are symmetrically located on the arc segment of the inner mold 2, which is convenient for disassembly of the straight line segment and the arc segment of the inner mold 2.

[0044] When the platform body 7 needs to be moved, it is only necessary to move the position of the corbel 1. The operation is simple and the installation and disassembly are convenient. The corbel 1 can be used multiple times, which saves the investment of manpower and material resources and reduces the construction cost. In addition, the corbel 1 is installed on the inner mold 2, and the concrete structure will not be damaged when the corbel 1 is disassembled and assembled.

[0045] like Figure 1 and Figure 3 As shown, in some embodiments, the above-mentioned fine-rolled threaded steel 3 includes a first fine-rolled threaded steel 31 and a second fine-rolled threaded steel 32, the first fine-rolled threaded steel 31 and the second fine-rolled threaded steel 32 are connected through a second sleeve 5, the lower end of the first fine-rolled threaded steel 31 is located in the second sleeve 5, the upper end of the second fine-rolled threaded steel 32 is located in the second sleeve 5, the first fine-rolled threaded steel 31 and the second fine-rolled threaded steel 32 are both threadedly connected to the second sleeve 5, and the lower end of the second fine-rolled threaded steel 32 is installed with a hanger 6. When the platform body 7 needs to be installed, it is only necessary to install the first fine-rolled threaded steel 31 and the second fine-rolled threaded steel 32 in the second sleeve 5 respectively, and when the platform body 7 needs to be removed, it is only necessary to unscrew the second fine-rolled threaded steel 32 from the second sleeve 5.

[0053] like Figure 4 As shown, further, there are four hand chain hoists 8, which are respectively fixed at the four corners of the platform body 7. By arranging the hand chain hoists 8 at the four corners of the platform body 7, it can be ensured that when the platform body 7 is moved, the force of the platform body 7 is balanced and the platform body 7 will not tip over.

[0054] like Figure 6 As shown, in some embodiments, the horizontal plate 12 includes two first channel steels 121, a top plate 122 and a bottom plate 123.

[0055] In some embodiments, the vertical plate 11 and the inner mold 2 are both provided with bolt holes, and the vertical plate 11 and the inner mold 2 are fixed by bolts in the bolt holes. During the construction process, when the corbel 1 needs to be removed, only the vertical plate 11 needs to be removed, which is simple to operate and will not damage the concrete structure.

[0056] In a second aspect, the present application provides a use embodiment of a hollow pier inner mold operation platform. When used,
