Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a concrete pouring device and a concrete pouring method.

[Conventional technology]

Conventionally, concrete placement into slabs and the like in general construction work has been carried out using horizontal distributors, simple distributors, and the like. In addition, for large-scale construction work, we use large-scale concrete pouring-related equipment, such as a dual-purpose crane and a dedicated distributor.

[Problem to be solved by the invention]

By the way, although the equipment related to concrete pouring is large, it only takes about 5 to 10 minutes for ordinary concrete pouring.
Because pouring is carried out about once a day, that is, the pouring-related equipment is used intermittently, it is uneconomical to permanently equip the construction site with the pouring-related equipment. . Therefore, general pouring-related equipment such as the above-mentioned horizontal distributor and simple distributor are installed and used when necessary, such as on the day of pouring.

However, the placement of these pouring-related equipment, especially the concrete pressure pipes on the pouring floor, is complicated, and the reaction force exerted on supporting points such as concrete pressure pipes during pumping is large, requiring special setup. ing. Furthermore, since multiple concrete pressure pipes are installed in a straight line or bent at a predetermined angle such as a right angle, the distance to the pouring point on the pouring floor can be adjusted according to the movement of the pouring point. There was a problem in that it was necessary to add or remove concrete pressure-feeding pipes each time the concrete was changed, and sometimes it was necessary to force-feed it in a roundabout way.

Therefore, it has been a challenge to make it possible to easily extend, shorten, change, etc. the concrete pressure-feeding route, and to easily set up support for concrete pressure-feeding pipes, etc.

[Means to solve the problem]

The present invention has been made in consideration of the above-mentioned problems, and includes a front part formed by a concrete pumping pipe connected to a concrete pumping machine running along a bending arm that is connected to a base machine so as to be able to rise and turn. It consists of a rear section in which a plurality of concrete pressure-feeding pipes are connected in a row, and has a joint part that connects adjacent concrete pressure-feeding pipes so that they can bend and extend and can rotate in the horizontal direction, and a truck that supports the joint parts. The present invention provides a concrete placing device characterized in that it supports horizontally movable joints that connect concrete pressure pipes in a bendable and horizontally rotatable manner; To provide a concrete pouring method, which is characterized in that a plurality of concrete pressure-feeding pipes are arranged in series, and concrete is poured by arranging the plurality of continuous concrete pressure-feeding pipes in a concrete pressure-feeding route, This solves the above problem.

[For production]

In the present invention, by bending and stretching the front section, the front section is caused to enter through an opening in the building or to stand upwardly on the side of the building. - The machine step part is connected to the front end, and the concrete pumping route can be changed by partially or totally bending, stretching, and rotating the rear step in the horizontal direction.

〔Example〕

Next, the present invention will be explained in detail based on an embodiment shown in FIGS. 1 and 2.

In the figure, reference numeral 1 denotes a concrete placing device, and the concrete placing device 1, as shown in FIG. , and a rear section 4 which is detachably connected to the front section 3 and into which concrete is fed.

The front section 3 has a concrete pressure feeding pipe 6 along a bending arm 5 which is pivotally connected to the base machine 2. By turning and raising the bending arm 5, the front part 3 can be used to prevent the building from entering through the opening of the building. It is provided so that it can be placed on the side of an object.

The rear section 4 is a structure in which a plurality of concrete pressure-feeding pipes 7 are connected in a bendable and extensible manner, and the concrete pressure-feeding pipe 7 on the front-stage side with respect to the above-mentioned front-stage section 3 is made horizontally rotatable via a joint section 8. The concrete pressure feeding pipes 7 are connected to each other so as to be rotatable in the vertical direction, and every two concrete pressure feeding pipes 7 are connected to be rotatable in the horizontal direction. Each of them is connected to the other end of the other connected concrete pumping pipe 7 via the joint part 8, and this rear part 4 can be bent and extended in whole or in part, and the joint parts 8 each It is provided so that it can also rotate horizontally around the center. And the rear section 4
A small distributor 9 is connected to the distal end of the distal end via a joint 8 as well.

Each of the joints 8 of the rear section 4 is supported by a cart 1o having ski cane legs with good sliding properties.
The joint portion 8 is provided so as to move horizontally on the existing slab as the member bends, extends, and horizontally rotates. Note that the means for moving the trolley is not limited to legs, and may include moving means such as wheels. Furthermore, it is also possible to automate concrete pouring by providing the small distributor 9 and each joint 8 with a drive unit, and controlling their respective operations with a computer.

When pouring concrete using the concrete pouring device 1, the front section 3 of the concrete pouring device 1 is extended toward the desired pouring floor, and the front section 3 of the concrete pouring device 1 is placed at the pouring floor. The rear section 4 assembled in step 1 is connected to form a concrete pumping route from the concrete pumping machine to the small distributor 9. During pouring, by moving the distributor 9 each time the concrete is poured, the rear section 4 is moved as a whole or partially by bending, stretching, and horizontally rotating, thereby changing the concrete pumping route.

〔Effect of the invention〕

As explained above, according to the present invention, the concrete pouring device has a front stage part formed by a bending arm connected to the base machine so as to be able to rise and turn, and a concrete pumping pipe connected to the concrete pumping machine to run along the bending arm. and a rear part in which a plurality of concrete pressure pipes are connected in series, and has a joint part that connects adjacent concrete pressure pipes so that they can bend and extend and can rotate in the horizontal direction, and supports the joint parts. It has a truck, and horizontally movably supports a joint part that connects the concrete pressure pipes in a bendable and horizontally rotatable manner, and a plurality of concrete pressure pipes are connected in series with the joint part interposed. Since concrete is poured by placing multiple continuous concrete pressure pipes in the concrete pumping route, the front stage of the concrete pouring equipment is
Installation is as simple as pumping concrete from a regular pump truck, and it can also be inserted horizontally through openings in buildings. In addition, the rear section placed on the pouring floor can be increased or decreased depending on the scale of the pouring floor, and can be easily bent, extended and rotated according to the pouring work, eliminating the need for a circuitous and fixed pumping route. can be changed at any time. Furthermore, since the joints are supported by the trolley, the load applied to the concrete pumping pipe during concrete pumping is dispersed, resulting in excellent practical effects.
