Description

Technical Field

[0001] The utility model relates to the field of concrete circular pipe culvert production, in particular to a drainage hole plug fixing device of a circular pipe culvert mould with drainage holes. Background Art

[0002] Concrete circular culvert mold plays a key role in the quality of the produced circular culvert, especially the circular culvert mold with drainage holes, which has higher requirements in terms of the fixation reliability of the drainage holes, ease of operation, quality assurance, etc.

[0003] At present, the drainage holes of circular culvert molds are fixed by horizontal insertion test, which is troublesome to disassemble and assemble. The horizontally inserted steel bars are easy to deform, and the finished product is greatly disturbed during removal. There is serious leakage at the drainage holes, which is not conducive to quality stability.

[0004] Therefore, it is necessary to develop a plug fixing device for the drain hole of a circular pipe culvert mold with a drain hole. Utility Model Content

[0005] The purpose of the utility model is to design a drainage hole plug fixing device for a circular pipe culvert mold with drainage holes in view of the deficiencies in the prior art, so as to solve the problems of complicated disassembly and assembly of the drainage hole plug of the circular pipe culvert mold, time-consuming work, large disturbance to the finished product, loose fixation of the drainage hole, and easy leakage of slurry.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a plug fixing device for a drain hole of a circular pipe culvert mold with a drain hole, which adopts the following technical scheme, including:

[0007] A device for fixing a drain hole pin of a circular pipe culvert mold with a drain hole, characterized in that it comprises: a plurality of mold reinforcement ribs are arranged on the side wall of the circular pipe culvert mold, a drain hole pin is arranged between the plurality of mold reinforcement ribs, the upper surface of the drain hole pin is pressed and fixed by transverse fixing steel bars, fixing steel plates are arranged on the upper part of the transverse fixing steel bars on the left and right sides of the drain hole pin, through holes are arranged on both sides of the fixing steel plates, fixing bolts are arranged to pass through the through holes to fix the fixing steel plates to the side wall of the circular pipe culvert mold, thereby fixing the transverse fixing steel bars and the drain hole pin.

[0008] Furthermore, a fixing groove is provided on the upper portion of the drain hole plug, the transverse fixing steel bar is embedded in the fixing groove and presses the drain hole plug tightly, a rubber ring is provided on the lower portion of the drain hole plug, and a pin is provided on the bottom of the drain hole plug.

[0009] Furthermore, the transverse fixed steel bars are used with a length close to that of the entire length of the circular culvert mold, and the positions where the transverse fixed steel bars pass through the reinforcing ribs of the mold are provided with open grooves.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model uses a fixing bolt welded to the mold surface and a fixing steel plate to press the transverse fixing steel bar onto the drain hole plug, so that the drain hole plug is tightly fixed on the mold, and then the slot on the top of the plug and the opening on the mold reinforcement rib are used to avoid displacement during the production process. When disassembling and assembling, it is only necessary to tighten or remove the fixing bolt with an electric wrench, and no disturbance is caused to the finished product, which greatly improves the construction efficiency. The rubber gasket on the drain hole is then used to change the rigid contact into elastic contact, so that the contact is tighter and the plugging effect is better.

[0012] The utility model is convenient for the production of circular pipe culverts, greatly improves the work efficiency, stabilizes the quality of finished products, and reduces the maintenance cost caused by component deformation. It has high safety, simple structure and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
