Description

Anti-splash device suitable for concrete plug-in vibrator

Technical Field

The utility model relates to a concrete placement process's construction technical field that vibrates, concretely relates to splashproof device suitable for bayonet vibrator of concrete.

Background

Concrete is poured into the formwork, a vibrator is needed to vibrate the concrete in the formwork, and bubbles in the concrete are eliminated through high-frequency vibration of the vibrator, so that the concrete is combined compactly. A common vibrator is usually an insertion vibrator, i.e. a vibrating rod. Typically, the vibrating rods used in the field are 50mm in diameter and 500mm long. During operation, concrete is horizontally poured into the formwork, and the vibrating rod is vertically inserted into the concrete for operation. The construction site is provided with a special tamping hand, and the cloth is distributed by taking the tamping hand as the center in the whole pouring process. When the vibrating rod is pulled out, the vibrating rod vibrates 5000-8000 times/min due to high frequency, and cement slurry attached to the rod body splashes around. According to actual field observation, constructors within 3m around the vibrating rod are polluted by cement slurry, and even the head and the face are polluted by the cement slurry, so that the health of a human body is seriously influenced.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

As shown in the attached drawings, the anti-splash device suitable for the concrete insertion type vibrator comprises a flexible fixing piece 1 and a cover body 2 made of a flexible product; the cover body 2 is of a structure with two open ends, wherein one end is a first open end, and the other end is a second open end; the opening of the second open end is larger than the opening of the first open end; the flexible fixture 1 is arranged at the first open end.

The opening of the first open end of the cover body 2 is larger than the outer diameter of the vibrating rod 4. The cover body 2 is sleeved outside the vibrating rod 4, and the first opening end and the second opening end are spaced along the length direction of the vibrating rod 4. The first opening end of the cover body 2 is connected with the low-frequency vibration part of the vibrating rod 4 through the flexible fixing piece 1. The low-frequency vibration part of the vibrating rod 4 specifically refers to the end of the vibrating rod 4 far away from the concrete, namely the end close to the hand held by the constructor. The flexible fixing piece 1 plays a certain role in buffering the vibration of the vibrating rod 4, and the cover body 2 is prevented from being separated from the vibrating rod 4 as far as possible. It should be ensured that the distance from the first open end to the second open end of the cover 2 is greater than or equal to the distance from the low-frequency vibration position to the high-frequency vibration end of the vibrating rod 4. The high-frequency vibration end extends into the concrete, and the low-frequency vibration position is positioned outside the concrete. The cover 2 moves with the movement of the vibrating rod 4. The vibrating rod 4 extends into the concrete, and the cover body 2 made of the flexible product is shortened towards the flexible fixing piece 1 due to the blocking of the concrete surface. When the vibrating rod 4 is pulled out of the concrete, the cover body 2 is extended and reset in a direction away from the flexible fixing member 1. When the vibrating spear 4 is completely pulled out, the cover body 2 completely covers the part of the vibrating spear 4 extending into the concrete, and the cement grout attached to the vibrating spear 4 is splashed to the inner wall of the cover body 2, so that splashing everywhere is avoided.

Since the concrete is in a fluid state during vibration, the second opening end of the cover body 2 is easily sunk into the concrete in the fluid state over time. In order to prevent the connecting end of the cover body 2 from sinking into the concrete, it is preferable that the mounting ring 3 is further included; the mounting ring 3 is connected with the side wall of the second open end and is matched with the opening of the second open end. The mounting ring 3 is sewn, e.g. glued, to the second open end of the cover 2. The inner diameter of the mounting ring 3 is larger than the outer diameter of the vibrating rod 4. The vibrating rod 4, when it is inserted into the concrete, can pass through the mounting ring 3. The mounting ring 3 can float on the upper surface of the concrete under the action of dispersion force, and further the cover body 2 is prevented from sinking into the concrete.

Preferably, the mounting ring 3 has an inner diameter of 50cm and an outer diameter of 51 cm.

The flexible fixing member 1 may be an adhesive product, and the first open end of the cover 2 is bonded to the low-frequency vibration portion of the vibrating bar 4 through the adhesive product. In order to facilitate the removal of the cover body 2, it is preferable that the flexible fixing member 1 is a rubber ring. The rubber ring fastens the first open end of the cover body 2 to the outer surface of the vibrating rod 4 at the low-frequency vibration position, so that the cover body 2 is convenient to mount and take down. When the vibrating rod 4 vibrates for a long time to cause the first opening end of the cover body 2 and the vibrating rod 4 to be connected and loosened, the loosening arrangement is further facilitated.

The cover 2 may have a polygonal cross section perpendicular to the axis L, and preferably, the cover 2 has a circular cross section perpendicular to the axis L.

The cover body 2 can be made of rubber, and preferably, the cover body 2 is made of a cement bag product. The cement bag has the advantages of low cost, convenient processing and the like. The main component of the cement bag is polypropylene resin.

The mounting ring 3 may be made of rubber, and preferably, the mounting ring 3 is made of plastic.

The utility model discloses a go up and do the utility model discloses a concrete implementation can be seen from the implementation, the utility model provides a can prevent the splash guard who is applicable to the bayonet vibrator of concrete that cement thick liquid splashes everywhere. The cement slurry is effectively prevented from splashing everywhere through the blocking of the cover body. Utilize the rubber circle to install the cover body in the low frequency vibration department of vibrting spear, not hard up the arrangement when being convenient for the operation. The mounting ring can float on the upper surface of the concrete under the action of dispersion force, and then the cover body is prevented from sinking into the concrete.
