Embodiment Construction

[0025] The present invention will be further described below in combination with principle diagrams and specific operation examples.

[0026] combine Figure 1 to Figure 4 As shown in , a double shut-off valve device suitable for pouring reinforced concrete under pressure, the double shut-off valve device is installed on the pre-opening hole 11 below the side wall of the steel pipe 1, wherein the double shut-off valve device includes: a first shut-off valve 2. The first cut-off valve 2 includes a first cut-off piece 21 and a first cut-off valve seat 22. Specifically, the shape of the first cut-off piece 21 is adapted to the shape of the steel pipe 1. In practice, the first cut-off piece The piece 21 is made of a steel plate, and it is made into an arc shape as a whole, and its curvature matches the curvature of the steel pipe, so that the whole of the first intercepting piece 21 can fit well on the surface of the steel pipe 1 . During implementation, a pre-opening hole 11 is ...

Abstract

The invention discloses a double-shutoff valve device applicable to press pouring of reinforced concrete. The double-shutoff valve device is installed in a preformed hole in the lower portion of the side wall of a steel pipe and comprises a first shutoff valve and a second shutoff valve; the first shutoff valve comprises two first positioning holes, a first shutoff piece and a first shutoff valve seat, wherein a first open pore formed in the lower half portion of the first shutoff piece is matched with the preformed hole, the first shutoff piece is fixed to the steel pipe, the first shutoff valve seat is provided with a second open pore which is matched with the first open pore, and the second open pore is aligned with the first open pore; the second shutoff valve comprises two second positioning holes, a second shutoff piece and a second shutoff valve seat, wherein the lower half portion of the second shutoff piece and the second shutoff valve seat are provided with a third open pore and a fourth open pore respectively, the third open pore and the fourth open pore are matched with the second open pore for installation, the second shutoff valve seat is installed on the first shutoff valve seat, and the second shutoff piece is installed between the first shutoff valve seat and the second shutoff valve seat. The double-shutoff valve device applicable to press pouring of the reinforced concrete has the advantages of being convenient to assemble and disassemble, high in compactness and rigidity, large in number of turnover times and the like.

Description

technical field [0001] The invention relates to the construction field, in particular to a double shut-off valve device suitable for downward pressure pouring of reinforced concrete. Background technique [0002] As a composite structural component, CFST has excellent compressive and flexural mechanical properties and good ductility, and is widely used in bridges and factory buildings, and is gradually used in super high-rise buildings. In the construction process of super high-rise building structures, due to its special process arrangement, the preferred method should be the "down-press method" construction of concrete-filled steel tubes. Among them, the design of the shut-off valve is the key to the implementation of the "down-press method". [0003] At present, the shut-off valves suitable for down-pressure construction mostly come from the construction nodes of industrial plants, and there are certain limitations in the application to super-high-rise concrete-filled ste...
