Problems solved by technology

[0005] In view of the above-mentioned related technologies, the inventor believes that when removing the inner mold, the operator must drill into the inner mold to remove the first helical crossbar and the second helical crossbar, and the space in the inner mold is quite narrow. Therefore, it is extremely inconvenient to remove the inner mold

Embodiment Construction

[0039] The following is attached Figure 1-9 The application is described in further detail.

[0040] The embodiment of the present application discloses a hollow slab girder inner mold that is easy to assemble and disassemble. refer to figure 1 and figure 2 , the hollow slab girder inner mold that is easy to disassemble includes a plurality of independent inner mold sections 100, and each independent inner mold section 100 includes a first half mold 110, a second half mold 120 and a mold for connecting the first half mold 110. The locking mechanism 200 with the second mold half 120 . The first mold half 110 and the second mold half 120 are mirror images, and the cross-sections of the first mold half 110 and the second mold half 120 are C-shaped. When using independent inner mold segments 100 to splice into an inner mold, the first half molds 110 on two adjacent inner mold segments 100 abut in the length direction sequentially, and the first half molds 110 on two adjacent...

Abstract

The invention relates to the technical field of road and bridge construction and particularly relates to a hollow slab beam inner mold convenient to disassemble and assemble. The hollow slab beam inner mold comprises a first half mold, a second half mold and a locking mechanism, wherein the locking mechanism comprises a first rotating rod, a second rotating rod, a first limiting block, a second limiting block, a connecting block and a steel cable; the other end of the first rotating rod is rotationally connected to the connecting block, one end of the second rotating rod is rotationally connected to the second half mold, the other end of the second rotating rod is rotationally connected to the connecting block, the first limiting block is fixedly connected to the first half mold, the second limiting block is fixedly connected to the second half mold, and one end of the steel cable is fixedly connected to the connecting block. The hollow slab beam inner mold can be opened under the condition that an operator does not enter the inner mold, then the first half mold and the second half mold are pulled out of the hollow slab beam, and therefore the inner mold is convenient to detach.

Description

technical field [0001] The application relates to the field of road and bridge construction, in particular to a hollow slab girder inner form which is easy to assemble and disassemble. Background technique [0002] The upper structure of the bridge mainly includes plate girder, box girder and T-beam, which refers to the cross-sectional form of the main beam of the bridge. Sub-prefabricated and cast-in-place, small box girder and box girder), etc., including I-shaped plate girders, hollow plate girders, etc. according to the shape. [0003] At present, the date of the announcement is July 14, 2020, and the Chinese utility model patent with the announcement number CN210999279U proposes a shrinkable inner mold for hollow plate beams and spiral struts, which includes support adjustment parts and symmetrically arranged two-sided molds. The middle part of the mold is movably connected, and the side mold includes an upper angle mold and a lower angle mold hinged with the upper ang...
