Description

[Detailed Description of the Invention] Purpose of the Invention Industrial Field of the Invention [0001] The present invention relates to a hopper device mounted on the tip of a crane for on-site pouring of ready-mixed concrete, and is mainly for pouring concrete for foundation of a house. It is used at times.

Conventional technology Conventionally, when placing a foundation concrete for a house, it was necessary to transfer it from a concrete mixer truck to a unicycle, move this unicycle to the construction site of the formwork, and pour it in. It took a lot of work and required a lot of workers.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention Therefore, the present invention is a dedicated hopper for accurately pouring concrete directly into a formwork in such a placing work of basic concrete for a house, which requires a lot of manpower and labor. It is an object of the present invention to provide a device so that a placing work can be performed quickly and surely at a low cost.

Configuration of the Invention Means for Solving the Problems The present invention is to provide support legs that reach the ground at the four corners of each upper vertical plate on the four sides of the hopper body that has a rectangular planar shape.
Sloping plates are installed in series with the upper vertical plates of the four sides of the main body, facing the rectangular opening formed in the lower central portion, and the left and right side surfaces of the slanting plate are the left and right upper vertical plates. It is covered with a lower vertical plate connected to the plate part, and an adjustment rod is installed at a proper position in the opening, and an opening / closing plate is provided at the bottom of this opening, and a flat rectangular shape is formed in the opening of the hopper body. The auxiliary hopper is made to exist, and guide plates are provided on both left and right sides of the rectangular lower opening of the auxiliary hopper, and the guide plates are fitted and attached to the concrete formwork.

Example (1) is a main body of a hopper having a rectangular shape in plan view, and supporting legs (2) having a length in contact with the ground are provided at four corners of upper vertical plates (1 ') on four sides of the main body. It is provided.

(3) (3), (3 ') and (3') are inclined plates that are connected to the four sides of the upper vertical plate (1 ') and are inclined toward the lower central part of the main body (1). Of these inclined plates, the front and back sides (3) and (3) can be seen from the outside, but the left and right side faces (3 ') and (3') cannot be seen from the outside, and the left and right upper vertical plates (1 ') ( 1 ') is covered by a lower vertical plate (1 ") (1") which is integrated.

(4) is the inclined plate (3) (3) (3 ') on the four sides
It is a rectangular opening formed by the center of the lower end of (3 '), and adjustment rods (5) and (5) are installed on the front and rear sides of this opening at appropriate intervals. This adjusting rod allows the fresh concrete to flow smoothly without being clogged at the opening. (6) is an opening / closing plate installed on the bottom surface of the opening (4), and the opening / closing plate is provided with support plates (7) on both left and right ends thereof.
(7) is stuck. The upper ends of the supporting plates (7) (7) are pivotally attached (8) (8) to the side surfaces of the lower vertical plates (1 ″) (1 ″). (9) is the left and right support plates (7)
(7) A planar U-shaped handle having both ends fixed to the lower side, and the handle operates up and down to open and close the opening / closing plate (6) with respect to the opening (4).

(10) (10) are hooks provided on both left and right sides of the main body (1), and the wire ends (a) of the crane are hooked on these hooks.

Reference numeral (11) is a rectangular auxiliary hopper to be mounted inside the upper part of a predetermined mold (b), and an opening (11 ') is formed on the entire bottom surface of the auxiliary hopper. Reference numerals (12) and (12) are guide plates provided in the front, rear, left and right sides of the opening (11 ') with a space between them so that the guide plates fit inside the form (b). become. A support rod (13) is installed between the two guide plates (12) (12).

(14) and (14) are mounting rods provided at the left and right ends of the auxiliary hopper (11), which are placed on the front and rear girders of the form (b). (15) (15) are handles provided on both left and right sides of the auxiliary hopper.

Then, the hopper of the present invention is placed in the discharge port of the concrete mixer truck with its opening (4) opened by the opening / closing plate (6), and a predetermined amount of fresh concrete is stored in the hopper. After that, attach the wire end (a) of the crane boom to the hook (10) of the hopper body (1).
It is hooked on (10) and the boom of the crane is rotated to guide it on the predetermined form (b). An auxiliary hopper (11) having a rectangular shape having substantially the same width as that of the mold is fitted on the mold (b) in advance via the left and right guide plates (12) (12). Then, when the handle (9) is gripped and moved upward to open the opening (4), the ready-mixed concrete is supplied to the inside of the mold (b) through the auxiliary hopper (11).

The adjustment of this ready-mixed concrete when it flows down is the adjustment rod (5).
(5).

Effect of the Invention Since the present invention has such a configuration, the time and time required for transporting ready-mixed concrete to a formwork location by a unicycle and then opening and placing it have been eliminated, and it is always quick. Moreover, a large amount of ready-mixed concrete can be supplied to the inside of the formwork, and a small number of people can complete the work of placing the concrete in a short time, which can significantly reduce the work cost. In addition, the hopper body and the auxiliary hopper both have a rectangular overall shape, and the openings are also rectangular so that they can be fitted and attached to the formwork, so the supply of fresh concrete into the formwork is extremely smooth. And the hopper body is not circular like the conventional one, so handling is extremely easy and the hopper after use is The inside can be easily and quickly cleaned, and its practical effect is extremely large.
