Description

Technical Field

[0001] The utility model relates to the technical field related to water absorption detection of building materials, in particular to a water absorption detection device for building materials. Background Art

[0002] The various materials used in construction projects are collectively referred to as building materials. There are many types of building materials, which can be roughly divided into: (1) Inorganic materials, which include metal materials (including ferrous metal materials and non-ferrous metal materials) and non-metallic materials (such as natural stone, burnt earth products, cement, concrete and silicate products, etc.). (2) Organic materials, which include plant materials, synthetic polymer materials (including plastics, coatings, adhesives) and asphalt materials. (3) Composite materials, which include asphalt concrete, polymer concrete, etc., are generally composed of inorganic non-metallic materials and organic materials. In addition, building materials can be divided into structural materials, decorative materials and certain special materials according to their different uses. Structural materials include wood, bamboo, stone, cement, concrete, metal, bricks and tiles, ceramics, glass, engineering plastics, composite materials, etc.; decorative materials include various coatings, paints, coatings, veneers, various colored tiles, glass with special effects, etc.; special materials refer to those used for waterproofing, moisture-proofing, anti-corrosion, fire-proofing, flame retardancy, sound insulation, heat insulation, thermal insulation, sealing, etc. For some special materials, the detection of water absorption performance is essential. At present, when testing the water absorption of special materials, a special bracket is usually set up, and a funnel is fixed on the bracket. When in use, the special material is placed on the bracket, and the water in the funnel is dripped onto the special material, and the water absorption after a certain period of time is observed and recorded.

[0003] The utility model patent with the announcement number CN211856252U discloses a device for detecting water absorption of building materials, which belongs to the technical field of construction equipment, and solves the problem that the dripping speed of the funnel in the prior art is fixed. When materials with different water absorption performance need to be detected, the dripping speed of the water droplets is fixed, so that when more detection water droplets need to be dripped, the initial time is more, which affects the efficiency of the detection. The utility model includes a support platform, a support for placing building materials is fixed on the support platform, a support cylinder is fixed on one end of the support, the support cylinder is connected to a support plate, a funnel is detachably connected to the support plate, a drip pipe is detachably connected to the bottom of the funnel, and a switch valve is installed at the tail end of the drip pipe. The utility model can select drip pipes of different diameters for installation according to different building materials to be detected by detachably connecting the drip pipe to the bottom of the funnel.

[0004] However, the above patent still has shortcomings: although the patent can control the dripping speed by replacing the dripping pipe, water drops will splash when they fall on the surface of the building material, causing a small amount of water to splash out of the device, making the data of the water absorption test of the building material relatively inaccurate.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 7 The utility model describes the above technical solution in detail through the following embodiments:

When the user controls the measuring cup 4 to move downward, the measuring cup 4 drives the fixing block 10, the fixing block 10 drives the connecting pipe 11, and the connecting pipe 11 drives the arc-shaped pipe 12. The arc tube 12 drives the sealing bead 14 through the limiting ring 13, so that the sealing bead 14 contacts the building material body 3. At the same time, the building material body 3 pushes the sealing bead 14 upward, so that the sealing bead 14 moves upward and separates from the limiting ring 13. The water inside the measuring cup 4 enters the fixed block 10, the connecting pipe 11, and the arc tube 12 in sequence through the drain port 9, and finally flows to the building material body 3 through the gap between the sealing bead 14 and the limiting ring 13.
