Rare building waterproofing expertise
Apr 16, 2024
01 Holes - there are empty drums in the concrete structure, and the local concrete or honeycomb is not particularly large.
02 Honeycomb - The concrete is partially loose, the mortar is less, the stone is more, the gap between the stones appears, the formation of honeycomb holes.
03 Hemp surface - concrete surface local lack of pulp, rough or there are many small pits, but no reinforcement phenomenon.
04 Roof - the roof of the open wall is covered by brick, tile, stone, concrete, reinforced concrete, galvanized iron sheet, etc.
05 Overhead thermal insulation roof - thin products made of sintered clay or concrete, covered on the roof waterproof layer and set up a certain height of space, the use of air flow to accelerate heat dissipation, play a role in heat insulation roof.
06 Water storage roof - a roof that stores a certain height of water on the waterproof layer of the roof to play a role in heat insulation.
07 Planting roofing - Covering the waterproof layer of the roof with soil or laying loose materials such as sawdust and vermiculite, and planting plants to play a role in insulating the roof.
08 Inverted roof - the roof with the insulation layer on top of the waterproof layer.
09 Upright roof - it is constructed as a roof under the waterproof layer of thermal insulation layer.
10 Cold matte - cold bituminous cementing material composed of petroleum asphalt, filler, solvent, etc.
11 Base treatment agent - In order to enhance the bonding force between the waterproof material and the base, the paint is pre-painted on the base before the construction of the waterproof layer.
12 Cold base oil - is the product of diluting asphalt with diluents (gasoline, diesel, kerosene, benzene, etc.). It is mostly used at room temperature for the bottom of the waterproof project, so it is called cold bottom oil.
13 strip bonding method - When the waterproof coil is pasted, the strip bonding method is used between the coil and the base. Each sheet and the base bond surface is not less than two, each width is not less than 150mm.
14 point bonding method - When the waterproof coil is pasted, the coil or punched coil is used as a point bonding construction method with the base. There are not less than 5 points per square meter, and the area of each point is 100mm*100mm.
15 Hot air welding method - The construction method of using hot air welding to bond waterproof coil.
16 Modified asphalt sealing material - Using asphalt as the base material, modified with an appropriate amount of synthetic polymer, adding filler and coloring agent, and processed through a specific production process of paste sealing material.
17 Synthetic polymer sealing materials - synthetic polymer materials as the main body, adding an appropriate amount of chemical additives, fillers and colorants, through a specific production process to form a paste sealing material.
18 Matrix reinforcement material - chemical fiber non-woven fabric, glass fiber mesh fabric and other materials used in the coating waterproof layer.
19 Tension - compression cycle - reflects the sealing material in the process of use, due to temperature changes caused by joint displacement and subjected to periodic tension, pressure cycles, to maintain the ability to seal.
20 Backing material - In order to control the filling depth of the sealing material, prevent the sealing material and the bottom of the joint and the sealing material between the deformable material.
21 block rigid waterproof layer: waterproof cement mortar mixed with waterproof agent is used as the bottom waterproof layer, the middle is paved with clay bricks and other blocks, and then the waterproof cement mortar is used to fill the joint and spread the waterproof surface layer.
22 Joint displacement - In roofing systems, changes in joint clearance caused by temperature and external forces.
23 Temperature stress - due to temperature changes, the structure or member produces extension or contraction, and when the expansion and contraction is limited, the structure or member will produce internal stress, called temperature stress.
24 Strength grade - Technical index of strength of concrete structural parts. It refers to the maximum stress that a standard specimen can withstand per unit area under pressure until failure. It is used as a technical index to evaluate the quality of concrete.
