Description

Molding for Concrete Deck Manufacturing {Molding for Concrete Deck Product}

The present invention relates to a mold for manufacturing a concrete deck, and more particularly, to a mold for manufacturing a concrete deck configured to manufacture a concrete deck having excellent strength and quality while reducing equipment costs.

In general, wooden decking is widely used as a flooring material for hiking trails, trails, sidewalks, building terraces, and the like. Wood decking has the advantage of being environmentally friendly, providing visual comfort, and absorbing shock and vibration.

For wooden decks, preservatives treated with preservatives are widely used to increase durability, and decks using these preservatives are exposed to snow, rain, and sunlight for a long time, causing deformation such as rotting or bending.

As a result, the wooden deck needs to be replaced after a certain period of time, or maintenance work such as antiseptic treatment is required.

Accordingly, in recent years, the demand for decks using concrete has been gradually increasing so that it is superior in durability and strength and maintenance is easy compared to wooden decks.

Registered Patent Publication No. 2011625 discloses a method for producing a concrete deck. Since the concrete deck production method disclosed in Patent Registration No. 2011625 manufactures a concrete deck by extrusion molding, the equipment cost is high due to the nature of extrusion molding, and there is a restriction that powdered silica sand should be used as an aggregate to prevent abrasion of the mold and obtain an excellent surface. It is difficult to follow and improve the strength.

The present invention has been made from a bird's eye view of the above points, and it is composed of a simple and new prefabricated structure to reduce equipment costs, can manufacture products with beautiful surfaces without using powder aggregates, and has excellent strength without increasing weight. To provide a mold for manufacturing a concrete deck capable of manufacturing a concrete deck, there is an object.

A mold for manufacturing a concrete deck proposed by the present invention includes a floor member having a rectangular shape, and a pair of sidewalls installed vertically with the floor member interposed therebetween, and the lower part is fastened using the floor member and fasteners A plurality of reinforcing hollow members installed at intervals along the width direction of the floor member in the deck forming space formed between the member and the upper portion of the pair of side wall members, and a pair of opening and closing both end surfaces of the deck forming space Including the door of

The bottom member is provided with a coupling groove formed in the inner surface "[" shape on both end surfaces in the width direction.

The side member has a coupling protrusion coupled to the coupling groove in the lower portion.

The coupling protrusion is formed to protrude in a shape corresponding to the inner surface shape of the coupling groove.

Here, the side wall member further forms a locking protrusion on which the upper surfaces of both ends of the bottom member are caught.

The bottom member is made of an aluminum extruded shape in which a plurality of hollows are penetrated in the longitudinal direction, and a plurality of protrusions are formed on the upper surface.

The side wall member is made of an aluminum extruded shape in which a plurality of hollows are formed through in the longitudinal direction, and a horizontal protrusion is formed in the center of the upper part.

Buckles are installed on both sides of the door so that one side of the door and the end surfaces of the floor member and the side wall member are in close contact with each other.

The reinforcing hollow member is made by using one of a round hollow steel pipe and a square hollow steel pipe, or both.

According to the mold for manufacturing a concrete deck according to an embodiment of the present invention, expensive equipment costs are required, and the construction is simple compared to the extrusion molding method using powder aggregate to obtain a beautiful surface, thereby reducing equipment cost, and using general aggregate. This beautiful product can be manufactured.
