Description

Cast-in-place concrete depth measuring rod

technical field

The utility model relates to a measuring rod, in particular to a cast-in-place concrete depth measuring rod .

Background technique

At present, during on-site construction, it is necessary to measure the thickness of cast-in-place concrete beams, slabs and various components from time to time, and the pouring of concrete needs to be completed before the initial setting of the concrete. If the thickness is not enough, the concrete needs to be poured again until the required thickness is reached; if the thickness exceeds the required thickness, the excess concrete needs to be removed until the required thickness is reached, which is time-consuming and labor-intensive, reducing work efficiency. Therefore, it is very necessary to provide a device capable of accurately measuring the thickness of cast-in-place concrete, and to measure the thickness of cast-in-place concrete conveniently and quickly .

The technical solution adopted by the utility model to solve the technical problem is: cast-in-place concrete depth measuring rod, including: support frame, level meter, green transparent sheet mark, upper cover, switch button, battery, light bulb, sliding sleeve, adjustment handle, Horizontal ring, long rod, and detection head; the measuring rod has a long rod with a scale on the surface and a hollow inside. The top of the long rod is screwed and fixedly connected to the upper cover, and the bottom end of the long rod is fixedly connected to the tapered detection head. ;The center position inside the upper cover is connected with a battery box and a light bulb, and the battery contained in the battery box is electrically connected with the light bulb; the upper end of the upper cover is matched with the switch button connected with the light bulb; the outer surface of the long rod is embedded with a green transparent sheet mark The outer periphery of the long rod is equipped with a sliding sleeve that can slide up and down, and the lower end of the sliding sleeve is fixedly connected with a circular horizontal ring, and the two sides of the horizontal ring are fixedly connected with the sliding sleeve through a support frame; the sliding sleeve is connected to the long rod through a screw The rod is fixed.

The middle part of the two side walls of the long rod is provided with a groove, and at the same time, the sliding sleeve is provided with an outwardly protruding protrusion matching the groove on the long rod, and the sliding sleeve can slide freely on the long rod; one part of the sliding sleeve There is a screw adjustment handle on the side. When the size of the object is measured, turn the adjustment handle to tighten the screw, and the sliding sleeve will be fixed at the measured size position, so that the measured object can be recorded conveniently and quickly. When measuring other objects, the screw can be loosened, and the sliding sleeve can slide freely.

The beneficial effects of the utility model are:

1. There are many scales, which can measure the thickness of different cast-in-place concrete;

2. Equipped with LED lights; when pouring concrete at night, turn on the lights to read the thickness of the pouring concrete conveniently and quickly;
