Interpretation of some technical terms: aproll, flashing, expansion joint, settlement joint, seismic joint, construction joint, toe binding, skirting line and parapet aproll: refers to the protective layer around the house, which is used to protect the foundation of the wall and disperse rainwater to the foot of the wall, with a general width of about 800 mm, including brick aproll, cast-in-place fine stone concrete and concrete aproll. This will make it easier to set the foundation. Simply put, cracks are more likely to appear after the walls of the house are not scattered. There is usually a cement floor half a meter away from the wall. Around the house or any building, see if it is a concrete floor about one meter away from the wall. That's a ball. Many buildings have "aproll", which, as the name implies, can spread out around buildings and outdoor terraces. There are many ways to shed water, not necessarily made of cement. "aproll" is an inclined slope protection around the external wall, with a slope of 3%-5% and a width of 0.6-1 m, and its purpose is to quickly drain the surface water. Diaphragm structure: 1.60 thick C 15 concrete sprinkling 1: 1 cement sand, 2. 150 thick 3: 7 lime-soil cushion is tamped and removed, which exceeds the apron edge by 500mm. 3. According to the order from top to bottom, compact 6% of the plain soil outward. Among them, "skirting line" and "skirting board" refer to the skirting board with a height of about 5 ~ 10 cm for the part of the wall near the floor to prevent people from kicking the white wall when they walk to the wall, and placing furniture can also prevent the furniture from being too close to the wall and damaging the wall; "Indoor dado" refers to the indoor dado. The function of dado is similar to dado and skirting board, but the height is generally about 1 ~ 2 meters from the ground. Overflow: fàn shuǐ 1. Ancient water name. The old road is located in the south of zhongmou county. Long Yan. 2. Ancient water name. The old road is now in the north of Cao County, Shandong Province, flowing out of Guji and northeast to the north of Dingtao County. Inject it into ancient Heze. Long Yan. Flooding is a kind of building waterproof technology. Generally speaking, it is actually the waterproof treatment of the intersection between the wall and the roof, that is, all the plane facades that need waterproof treatment. To put it bluntly, it is to wrap the corner with waterproof material. Different from aproll, its structural key points and practices are as follows: (1) The coiled material of the falling roof is continuously laid on the vertical wall to form coiled material waterproof, and the flooding height is not less than 250 mm ... (2) At the intersection of the roof and the vertical parapet, the mortar leveling layer should be brushed into an arc or a 45-degree inclined plane, and the coiled material adhesive should be brushed to make the coiled material adhesive dense, so as to avoid the coiled material being overhead or broken, and another layer of coiled material should be paved. (3) Do a good job of fixing the coiled material with running water to prevent the coiled material from sliding on the vertical wall. The general practice is to cut a long slot in the vertical wall, press the fallen coil into the slot, nail it with waterproof battens, then embed it with sealing material and seal it with cement mortar for protection. The wall above the trough should also be waterproof. Popular explanation: Flooding refers to the waterproof practice of parapets, overhangs or high and low roof walls. Its main function is to ensure that parapets, overhangs and high and low roof walls are not washed away by rain and protect the waterproof layer of the rest of the roof (from water). Flooding is generally at the junction of roof, roof and parapet! In order to prevent rainwater from leaking, aproll is on the first floor outside! That is to say, make an outdoor elevation of +_0.000, and make a slope of about 2% and a width of about one meter along the periphery of the building to prevent rainwater from leaking from the gap between the building and the terrace! Aproll is usually associated with strangulation! Expansion joints and contraction joints are preset gaps in buildings to reduce the influence of expansion and contraction joint deformation of materials on buildings. Settlement joint is a preset gap in the building to reduce the influence of uneven deformation of foundation. Seismic joints in seismic joints are to reduce or prevent adjacent structural pieces. When the concrete construction joint cannot be continuously poured at one time due to technical or construction organization reasons, the lap joint or post-cast strip shall remain in the specified position of the structure. The function of foot binding is to prevent the erosion of groundwater and rainwater dripping from eaves, thus protecting the wall surface, ensuring indoor dryness and improving the durability of buildings. The height of column foundation is generally the height difference between indoor ground and outdoor ground. Special words used in the decoration of the skirting line of Schleswig-Holstein's feet In the room design, the internal corner line, waist line and skirting line play the role of visual balance, and their sexy lines, materials and colors echo each other indoors, which can play a better beautification and decoration effect. Another function of the baseboard is its protection. The baseboard, as its name implies, is the area where the feet can kick, so it is more vulnerable to impact. Doing baseboard can make the wall firmly combined with the ground, reduce the deformation of the wall and avoid the damage caused by external force collision. In addition, the baseboard is easier to scrub, and it is also convenient to scrub if the floor is splashed with dirty water. The baseboard is made of porcelain, wood and marble. The height of the skirting line has been decorated before, and it is generally around 10 cm. In recent years, the height of the skirting line has decreased a little, and families generally choose the height of 6.6 cm or 7 cm, because it can make the interior decoration look more exquisite and beautiful. The decoration drawing is generally 150 mm parapet, which is a form of building wall. Originally called the female wall, it was also called the female wall. The actual name is cornice wall, which is called battlements by the people. It is a low wall higher than the roof and the city wall. From the architectural form, parapet is a way to connect the shape of roof and external wall, and later it gradually developed into a special protective wall. The origin of the parapet is very interesting. According to folklore, in ancient times, due to the shackles of feudal ethics, a large family deliberately built a wall on the roof and wall to prevent their daughters from going out casually, but the girls couldn't stay at home and couldn't help the stimulation and temptation from the outside world, so they quietly climbed to the roof or high wall and looked out through the low protective wall. Over time, they are called railings. There are various architectural forms of parapets, generally speaking, there are solid walls and some with observation holes. The origin of the name of the parapet An ancient bricklayer was busy with work and had to take her little daughter with him. One day, when she was building a house on the roof, her little daughter accidentally fell and died. The craftsman was heartbroken, let the tragedy happen again, and then built a low wall on the roof. Later people named it "parapet", which was a joke. The real origin: "Building French Style" in the Song Dynasty "to put it mildly, it is the meaning of a woman to her husband in a city", which is the part above the edge of the city wall. Parapet is an architectural term, which refers to a low wall whose outer wall is higher than the roof. We often see it in Ming and Qing architecture. This is one of the organized drainage schemes for the roof. When overhangs are not expected due to architectural modeling and other reasons, the outer wall is usually raised to seal the roof, and this part of the outer wall above the roof is called parapet. Simply put, it is to wrap the rainwater on the roof and collect it in one place and then discharge it outside the house. If there is no parapet, gutter and eaves gutter, rainwater will flow down the surrounding walls, and the foot of the outer wall will often be eroded by splashing rain, which will reduce the firmness and durability of the outer wall; Rain dripping from the eaves may affect the sidewalks, and so on. When the building is high and the rainfall is heavy, these shortcomings are more prominent.
