Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gutter fastener for holding a drain gutter on a chute of a concrete mixer.

[0002]

[Prior Art]

 A device shown in FIG. 5 is conventionally known as this type of device. FIG. 5 is an explanatory diagram showing a usage state of a conventional example. During ready-mixed concrete construction, a sink gutter 3 is hung and held on a lower end portion 2a of a chute 2 from which a concrete concrete (not shown) is poured from a concrete mixer 1. Numeral 4 is a tightening member which is applied to the chute 2 by holding the sink gutter 3 and holds the chute 2 by winding the chute 2 and the drain gutter 3 along the outer side thereof. There is. During the work, ready-mixed concrete is poured from concrete 1 through chute 2 into drain gutter 3 and sent to the place of use. The mixer 1 arriving at the site drains the loaded ready-mixed concrete through the shoot 2 and the sink gutter 3 in the shortest possible time. It was

[0003]

[Problems to be solved by the device]

 However, in the conventional gutter tightening of the drain gutter, depending on the situation of the construction site, it is sufficient that the concrete can be directly drained from the chute 2, but in general, in order to hold the gutter 3 to the chute 2, When searching for fastening members 4 such as wires and ropes, it was difficult to find them, especially when the construction site was dark, and the work had to be interrupted. Moreover, since the chute 2 is made of a relatively thin steel plate and has a three-month cross section, it may be deformed if it is tightened too much with a rope or wire. Therefore, especially with a driver of a mixer of a new car. There was a problem that a trouble occurred with the worker, the tightening member 4 was loosened, and the casting gutter 3 could come off from the chute 2 while pouring fresh concrete. The present invention has been made to solve such a problem, and since it is composed of a turnbuckle part with a handle in the center and a chain, it is operated by hand, so it is caused by overtightening or loosening. It prevents falling off, enables quick and efficient concrete work, and at least part of the chain is fitted with a fitting member so that it can be firmly tightened and removed without damaging the shoe or sink. It aims to provide a cleat mixer chute and sink gutter fasteners.

[0004]

[Means for Solving the Problems]

 For this reason, the chute of the concrete mixer of the present invention and the gutter tightening tool of the sink gutter are screwed with screw rods having hooks at both ends, and a turnbuckle part with a handle at the center and a turnbuckle part. One end is fitted to the hook of the screw rod screwed to one end, and the other end is detachably attached to the hook of the screw rod screwed to the other end. By covering the fitting member in a part, the above-mentioned purpose is achieved.

[0005]

[Action]

 According to the present invention, screw bars having hooks are attached to both ends of the turnbuckle part, and the turnbuckle part with a handle in the center allows the gutter to be manually operated to quickly and securely tighten the gutter in a short time. It can be tightened without slack or looseness, and since the fitting member is mounted on at least a part of the chain, the drain gutter can be tightened and removed without damaging it.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing an embodiment of the present invention, FIG. 2 is a perspective view showing the same use state, and FIG. 3 is an explanatory view showing a state where the concrete mixer is attached. The same parts as or corresponding parts in the above-mentioned conventional example are denoted by the same reference numerals to avoid duplication of description. In the figure, 7 is a turnbuckle portion, 8 is a handle provided at the center of the turnbuckle portion 7, 9 and 10 are one end and the other end of the turnbuckle portion 7, and 11 and 12 are one end 9 of the turnbuckle portion 7. , And threaded rods 13 and 14 respectively screwed to the other ends 10, and hooks 13 and 14 provided at the ends of the threaded rods 11 and 12, respectively. One of the threaded rods 11 and 12 is provided with a left-hand thread and the other threaded rod is provided with a right-hand thread. Depending on the direction in which the handle 8 is rotated, the threaded portions of the threaded rods 11 and 12 are hooked. It is designed such that 13 and 14 move away or move toward each other. Reference numeral 15 is a chain in which one end 16 is fitted to the hook 13 provided on the threaded rod 11 and the other end 17 is detachably attached to the hook 14 provided on the screw 12. This is a fitting member that is installed on at least a part of the chain 15, and in this embodiment, a case will be described in which the fitting member is made of synthetic resin.

The operation will be described. With the chute 2 on the lower end 2a of the chute 2, wind the chain 15 along the outside of the chute 2 and the chute 3 so that the handle 8 of the turnbuckle part 7 is on the upper side. , The other end 17 of the chain 15 is engaged with the hooking portion 14 of the screw rod 12 provided on the other end 10 of the turnbuckle portion 7 to such an extent that the looseness is reduced, and then the turnbuckle portion 7 is attached by the handle 8. By turning, the gutter 3 is fastened to the chute 2.

Then, when the fresh concrete in the concrete mixer 1 is poured into the chute 2, the fresh concrete naturally flows down from the chute 2 through the drain gutter 3 to a place to be constructed. At the time of removal, the turnbuckle portion 7 is turned in the opposite direction by the handle 8 so that the drainage gutter 3 is loosened, so that it can be easily removed. In this case, since the handle 8 is operated, over-tightening and loosening does not occur, the work can be performed efficiently, and the fitting member 18 is externally mounted on the chain 15, so that the shoe 2 and the drain trough 3 are not attached. Does not hurt. According to one embodiment of the present invention, a concrete mixer chute and a sink gutter fastener are a concrete mixer 1 and a concrete mixer chute 3 which holds a concrete gutter 3 for discharging fresh concrete. A gutter tightening tool for a gutter, in which both ends 9 and 10 are screwed with screw rods 11 and 12 having hooks 13 and 14, respectively, and a turnbuckle portion 7 provided with a handle 8 in the center and a turnbuckle portion. 7, one end 16 is fitted to the hook 13 of the screw rod 11 screwed to one end 9 of the screw 7, and the other end 17 is attachable / detachable to the hook 14 of the screw rod 12 screwed to the other end. Since it is composed of the configured chain 15, it can be operated in a short time without being overtightened or loosened because it is operated by hand, and the chute 2 and the chute 2 can be provided by mounting the fitting member 18 on at least one part of the chain 15. Scratching the sink 3 That there is an effect that it is not. (Other Embodiments) In the above-described embodiment of the present invention, the chute of the concrete mixer and the gutter fastening tool of the drain gutter which are mainly used for the large-sized concrete mixer 1 have been described, but the one shown in FIG. 4 is a small concrete. This is the same as the above-described embodiment except that it is a concrete mixer seat and a drain gutter fastener applicable to the mixer 1, the turnbuckle part 7 has a hollow part, and the structure is made lighter.

[0009]

[Effect of the device]

 As described above, according to the concrete chute and the gutter tightening tool of the drain gutter of the present invention, a pair of screw rods having hooks at one end and the other end are screwed together, and a turn with a handle at the center is provided. One end of the buckle and the threaded part of the threaded rod screwed into one end of the turnbuckle are fitted, and the other end is removable from the threaded part of the threaded rod screwed into the other end. Since it is operated by hand, it can be operated by hand without over tightening and loosening, and work can be done efficiently in a short time.Because at least a part of the chain is fitted with a fitting member, it will damage the chute and the gutter. The effect is that it can be securely attached and detached without any trouble.
