Abstract
The utility model discloses a sealed negative pressure device for investigating water-tightness of structures. The utility model is formed by the way that a small vacuum pump, a sealing cover and a vacuum suction pipe are connected. The sealing cover is transparent. A pressure meter is arranged on the sealed cover. The sealing cover can be the structure of a rectangle, a circle, a tri-dimensional triangle or a right triangle arranged on the two ends respectively. The utility model is used for investigating water-tightness of different parts of a building. The utility model is small in volume and light in weight. The utility model provides accurate investigating results and solves the difficulty of uneasy accurate position of the seepage points of the water-proof parts of a building.
Description
The utility model is a kind of pick-up unit that is used to seek the building waterproof breakthrough.
Seepage is the common disadvantage of buildings.The seepage at positions such as roofing, toilet, basement can have a strong impact on the use of buildings.The appearance of seepage is caused by various factors, and wherein seepage appears in the quality of building waterproof layer quality and maintenance degree and buildings direct relation.Buildings occurs must in time searching out breakthrough after the seepage and repairs.The method of seeking leakage of buildings point now still relies on workmen's experience.Owing to there is not effective checkout equipment, only judge that according to the terminal point water mark of percolating water in building structure breakthrough tends to occur error, reason is that many breakthroughs are not the position that is in terminal point water mark.
The purpose of this utility model provides a kind of waterproof sealing negative-pressure detection device.This device is to utilize vacuum to produce negative pressure principle physical detection is carried out in the Suspected Area.Can conclude the position of breakthrough quickly and accurately by the physical phenomenon of observing Suspected Area generation in the testing process.Solved in the past the problem that only macroscopic examination by rule of thumb is difficult to determine breakthrough.
The utility model is realized by following scheme.Pick-up unit is made up of vacuum pump, seal closure and vaccum suction pipe.The suction pipe two ends are connected with seal closure with vacuum pump respectively, and seal closure is a transparent substance, and manometer is set on it.The geometric configuration of seal closure can be different structural forms such as rectangle, fusiformis, circle, 3-D triangle or both wings square, so that special the detection done at the different waterproof of buildings position, for example position, plane, position, right angle, inner corner trim position and the detection at position, the mouth of a river down.During detection, remove the foreign material at doubtful point position earlier, look the shape that doubtful point position shape is selected seal closure.Special-purpose soap lye is applied to the doubtful point position, then seal closure is covered on the doubtful point place, cover mouthful edge and detected position are fitted tightly.Open vacuum pump, observe the reading and the doubtful point surface condition of instrument simultaneously.If the soap lye on doubtful point surface is a breakthrough through vacuum then foaming place of bubbling.If reach doubtful point position no change behind the certain vacuum degree, this place's ne-leakage be described.Below engaging accompanying drawing is described further embodiment of the present utility model.
Fig. 1 is the rectangular seal cover arrangement synoptic diagram of portable building waterproof sealing negative-pressure detection device.Fig. 2 is round seal closure organigram.Fig. 3 is a 3-D triangle seal closure organigram.Fig. 4 is a both wings square seal closure organigram.
With reference to accompanying drawing, the sealing negative-pressure detection device is by miniature rotary-vane vaccum pump (not shown), and transparent sealed cover and rubber vaccum suction pipe (3) are formed.The suction pipe two ends are connected with the connection (2) of vacuum pump and seal closure (1) respectively.Seal closure (1) is provided with another connection (6), is used for being connected with vacuum instrumentation (4).The cover mouth perimeter bond of seal closure has flexible sealing strip (5) so that fit closely knit with the surface at test position.The seal closure of rectangular configuration is used for the detection at position, plane.The seal closure of rounded configuration is used for the detection at position, the mouth of a river down.The seal closure of 3-D triangle structure is used for the detection at inner corner trim position, and its cover mouth cross sectional shape is equilateral triangle or isosceles triangle.The drift angle of its two ends wing plate of the seal closure of both wings right-angled configuration is 90 °, as the special-purpose seal closure of right angle location detection.
The utility model volume is little, in light weight, easy to carry, and its testing result is very accurate, and to improving the monolithic architecture waterproof quality, in time the clear quality common fault has played positive facilitation.
