Abstract

The utility model provides a bridge drain hole pre-embedding device which can be used in a turnover way, and is welded and manufactured by steel plates; the shape of the embedded device is consistent with that of the drain hole, and the external dimension of the embedded device is 5-10mm larger than that of the drain pipe; the upper end and the lower end of the embedded device along the axial direction are respectively provided with a sealing surface, and a handle is welded on the outer side of the sealing surface positioned at the upper end; the outer surface of the pre-buried device is coated with a release agent; after the bridge steel bars are bound, the embedded device is installed and fixed on the top surface of the bridge; and after the concrete is poured and solidified, taking the embedded device out of the solidified concrete to form the water drainage holes in the concrete. The bridge water outlet pre-embedding device capable of being used repeatedly is simple and convenient to construct, can be used repeatedly in a circulating mode, and is energy-saving and environment-friendly.

Description

Bridge water outlet pre-embedding device capable of being used in turnover mode

Technical Field

The utility model relates to a building engineering field especially relates to bridge outlet.

Background

In order to reduce the water accumulation of the bridge deck, a certain number of water drain pipes are required to be arranged on the bridge deck to bear the rainwater drainage task. The common drain pipes in bridges mainly comprise cast iron drain pipes, and the installation of the cast iron drain pipes is generally realized by reserving drain pipe installation holes when the bridges are cast in situ or prefabricated. At present, in domestic construction, a method for pre-burying a PVC pipe is mainly adopted for reserving a bridge drain hole, and a section of PVC circular pipe with the outer diameter larger than that of the designed drain pipe is pre-buried at a design position. The method is adopted to reserve the drain holes, the number of PVC round pipes needing to be put in one time is large, material waste is caused, the PVC round pipes with the holes formed in advance need to be removed and cleaned before subsequent drain pipes are installed, meanwhile, a bridge floor water inlet is chiseled according to the size of a horn mouth of the drain pipe, a working face is reserved for installing the drain pipe, the pipeline needs to be temporarily fixed when the drain pipe is installed, the peripheral gaps are tightly filled, the process is complex, the appearance quality cannot be guaranteed, and the installation work efficiency of the drain pipe is integrally low.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the main technical problem that a bridge outlet pre-buried device that can have enough to meet the need the use is provided, and the construction is simple and convenient, and the device can turnover used repeatedly, energy-concerving and environment-protective.

In order to solve the technical problem, the utility model provides a reusable bridge drain hole pre-embedding device which is welded and manufactured by steel plates; the shape of the embedded device is consistent with that of the drain hole, and the external dimension of the embedded device is 5-10mm larger than that of the drain pipe; the upper end and the lower end of the embedded device along the axial direction are respectively provided with a sealing surface, and a handle is welded on the outer side of the sealing surface positioned at the upper end;

the outer surface of the pre-buried device is coated with a release agent; after the bridge steel bars are bound, the embedded device is installed and fixed on the top surface of the bridge; and after the concrete is poured and solidified, taking the embedded device out of the solidified concrete to form the water drainage holes in the concrete.

Compared with the prior art, the technical scheme of the utility model possess following beneficial effect:

the utility model provides a bridge outlet pre-buried device that can have enough to meet need the use carries out pre-buried when the cast-in-place or prefabricated construction of bridge, once only reserves the shaping with the outlet according to the outlet shape according to the design position, need not unnecessary supplementary process during the outlet installation, and the construction is simple and convenient, and the device can the turnover used repeatedly, energy-concerving and environment-protective.

Drawings

Fig. 1 is a schematic view of a pre-buried device in a preferred embodiment of the present invention;

fig. 2 is a schematic view of the drain pipe according to the preferred embodiment of the present invention.

Detailed Description

The following is a further description of the embodiments of the present invention, but the embodiments of the present invention are not limited thereto.

Referring to fig. 1 and 2, the reusable bridge drain hole pre-embedding device is manufactured by welding steel plates; the shape of the embedded device is consistent with that of the drain hole, and the external dimension of the embedded device is 5-10mm larger than that of the drain pipe; the upper end and the lower end of the embedded device along the axial direction are respectively provided with a sealing surface 1 and a sealing surface 2, and a handle 3 is welded on the outer side of the sealing surface 1 at the upper end;

the outer surface of the pre-buried device is coated with a release agent; after the bridge steel bars are bound, the embedded device is installed and fixed on the top surface of the bridge; and after the concrete is poured and solidified, taking the embedded device out of the solidified concrete to form the water drainage holes in the concrete. And then the installation of the drain pipe can be completed only by inserting the drain pipe into the drain hole.

The bridge drain hole pre-embedding device capable of being used in a circulating mode is pre-embedded during bridge cast-in-place or prefabricating construction, the drain hole is formed in a reserved mode at one time according to the shape of a drain pipe and the design position, redundant auxiliary processes are not needed during installation of the drain pipe, construction is simple and convenient, the device can be used repeatedly in a circulating mode, and energy is saved and the environment is protected.

The above description is only an exemplary embodiment of the present invention, and the scope of the present invention should not be limited accordingly. The equivalent changes and modifications made according to the patent scope and the content of the specification of the present invention should still fall within the scope covered by the present invention.
