A water seepage test device for building exterior walls for construction supervision

Abstract

The invention relates to a water seepage test device for building exterior walls for building supervision, comprising a detection frame and a water supply device installed on the detection frame. The detection frame includes installation rods, and a spray pipe is installed between the two installation rods. There are spray holes on the side near the wall. The water supply device includes a sprinkler tank and a water pump. The water inlet of the water pump is connected with the sprinkler tank, and the water outlet of the pump is connected with a water outlet pipe, and the other end of the water outlet pipe is connected with the spray pipe. A height adjustment device is installed on the detection frame. The height adjustment device includes two adjustment bars and two adjustment chains. The two ends of the adjustment bars are respectively fixedly connected with the two adjustment chains. On the adjusting crossbar, an adjusting cylinder is fixedly installed on the mounting rod, the adjusting chain is penetrated in the adjusting cylinder, an adjusting motor is fixedly installed on the mounting rod, and the output shaft of the adjusting motor is fixedly installed with an adjusting sprocket engaged with the adjusting chain. Its structure is stable, and it is not easy to fall off the wall.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a water seepage test device for building exterior walls used for construction supervision. Background technique [0002] With the increase of high-rise buildings, water seepage on the outer walls or windows of high-rise buildings has increased. During construction, there are more water leaks. When checking for water seepage on the outer walls, it is often necessary to spray water with water pipes or to check when it rains. , find out a few leaks to repair, did not check the potential leaks carefully, caused the hidden danger of water leakage to the outer wall of the building. In the future use process, when the rain is heavy, there will be water seepage on the outer wall or the window, which seriously affects the normal use of the building. [0003] For example, the Chinese patent with the notification number CN108827546B discloses a water seepage test device for ...

Problems solved by technology

[0004] However, this structure only uses the air suction cup to adsorb the detection device on the wall. When the first air suction cup is pulled by the first driving cylinder, the first air suction cup is separated from the wall, and the fixed frame is under gravity. When the sliding groove moves downward relative to the sliding block under the action of the sliding groove, the fixed frame will collide with the sliding block

It is easy to cause a gap between the second suction cup on the sliding block and the wall, which cannot be tightly fitted, which will cause the second suction cup to fall off the wall

Although it connects the pull ring by being provided with a rope, the fixed frame is not easy to fall off, but there is a gap between the first suction cup and the second suction cup and the wall, and the whole fixed frame is not easy to be adsorbed on the wall again. body, making subsequent testing impossible

It requires workers to adjust, which is very troublesome to use
