l13j1 house 103A 1F1 on the flat roof practice?

12J1 is the atlas number, everyone knows it! House 105 is numbered, 2F1 is the waterproof material in the attached table, and the flat roof is not the same as the slope roof. 50b1 stands for insulation, 50 stands for thickness, and b1 is the material, got it.

Roof refers to the surface of the roof of a building, and also refers to the part between the ridge and the eaves. This part occupies a larger area of the roof, or the roof is the larger part of the roof. Generally, it includes concrete cast-in-situ floor, cement mortar leveling layer, thermal insulation layer, waterproof layer, cement mortar protective layer, drainage system, parapet wall and lightning protection measures, etc., and the construction of tile surface (hanging tile) during special projects.

Green roofing. The matrix layer is a mixed matrix layer, which is mixed with screened lightweight materials to reduce the load-bearing capacity of the roof, and the volume ratio of each matrix is: peat: vermiculite:

Perlite: sawdust = 4:3:

2:1, then mix the substrates well, and the thickness of the mixed matrix layer is 15 cm. The main function is to carry the plant layer and provide the necessary nutrients and water for the plant layer to grow.

The filter layer filter layer is made of polyester fiber non-woven fabric, which has good filtration, drainage, isolation, and the material is light in weight, high tensile strength, good permeability, etc., which can not only permeable but also isolate the fine particles in the planting soil, the main function is that when the water flows through the matrix layer, the good air permeability and permeability of the needle-punched geotextile are used to make the water flow through, and the soil particles, fine sand and small stones are effectively intercepted to prevent the drainage layer from being blocked.

House 105-1F1-40B1 is an index of construction practices, and the index number can be found in the engineering practice table of the general description of the building, followed by the corresponding roofing construction practices (including roof leveling, insulation, waterproofing, etc.).

12J1 is the atlas number, house 105 is the number, 2F1 is the material in the waterproof material selection table in the attached table, and the flat roof is not the same as the slope roof. 50b1 stands for insulation, 50 stands for thickness, and b1 is the material.

On January 6, 1956, People's ** published an editorial entitled "Speed up the design progress and supply drawings early". It is pointed out that "the extensive use of standard designs and the reuse of drawings is the most effective and fundamental measure to speed up the design." On May 8, 1956, the Decision on Strengthening Design Work was made, emphasizing the need to accelerate the preparation and widespread adoption of standard designs.

In October 1956, the State Construction Committee promulgated China's first normative document for standard design work, "Interim Measures for the Preparation, Examination and Approval and Use of Standard Design", and established the Standard Design Institute of the State Construction Committee, which marked the birth of China's engineering construction standard design. Over the past 50 years, China has compiled more than 1,900 national architectural standard designs.

Atlas History:

The design of national building standards is an important part of engineering construction standardization, an important basic work of engineering construction standardization, and an important general technical document in the field of construction engineering.

China's engineering construction standard design originated in 1956. At the time of the first five-year plan of the founding of the People's Republic of China, the country is waiting to be rejuvenated and all industries are waiting to be lifted. In order to meet the needs of large-scale economic construction throughout the country, especially to solve the contradiction that "design could not catch up with construction, and construction could not catch up with construction demand" at that time.

Kiss! Hello, happy to answer your <>

Pro-12J1 House 103 Roofing Practice Page 138 Content The practices of the Venerable Roof and the In-Person Level are as follows: The difference between the structure of the Venerable Roof and the Unriser Roof is mainly due to the difference in the waterproof protective layer. In addition to the waterproof layer of the protective membrane, the Venerable Roof Protective Layer should also consider the wear and tear of the roof by human activities, so it is necessary to choose a material with strong and good wear resistance, such as a brick-laying or cast-in-place concrete protective layer.

On the side of the roof protective layer, only the protective effect of the waterproof layer of the membrane is considered, and the protective layer is generally used to paste aluminum foil, sprinkle mung bean sand or brush light-colored paint. The difference between the Venerable roof and the non-Venerable roof is that the bearing capacity of the roof is different, and if the practice has been clarified, it will not affect the calculation of the engineering quantity. 1. The engineering methods are different, the Venerable Master's roof is generally completed after the waterproof layer is completed, while the Venerable Master's roof has to be made after the waterproof layer is completed, and the floor layer is also made.

2. There must be a staircase leading to the roof floor on the roof, and a manhole can be left on the roof without a person to go up to the roof layer by climbing the ladder. The safety requirements for the roof are also different, the roof can not have a parapet wall or a parapet wall, and the height is not limited, while the roof of the upper person generally has a parapet wall, and the height of the parapet wall is limited, and the height of the parapet must meet the safety requirements, generally not less than 1. wheel which 2 meters.

3. The functions are different, the Venerable Person's roof can be used for people to carry out activities on the roof, and the virtual roof does not have this function. Hope mine can help you <>

Summary. The roofing method of 12J1 House 105 is to clean the base layer, paint plain ash, and lap the insulation layer. 1. The structural layer or decoration layer in the upper part of the indoor space is mostly covered for the needs of indoor aesthetics and thermal insulation.

2. Purlins, also known as purlins and trusses, are horizontal roof beams perpendicular to roof trusses or rafters. 3. The arched corrugated rigid roof is pressed into a curved steel channel plate with wrinkled corrugations by a special forming unit. ”

Hello dear! I've seen your question and I'm trying to sort out the answer, and I'll get back to you in five minutes, so please wait a minute

The roofing method of 12J1 House 105 is to clean the base layer, paint plain ash, and lap the insulation layer. 1. The structural layer or decoration layer of the upper part of the indoor space is burned, and most of the roofs are set up for the needs of indoor beauty and thermal insulation. 2. Purlins, also known as purlins and trusses, are horizontal roof beams perpendicular to roof trusses or rafters.

3. The arched corrugated rigid roof is pressed into an arc-shaped steel channel plate with wrinkled corrugations by a special side bridge type unit. ”

For the roof of Room 103 on the 12th floor, page 138 focuses on the practice of the upper and lower levels. The practice of not going to the human level is not to use a single-layer waterproofing membrane at the human level, and the roofing waterproofing layer material is mainly made of polyvinyl chloride (PVC) waterproofing membrane. The thickness of the waterproofing membrane is carried out according to the design requirements, and it is necessary to achieve an effective waterproof effect.

A protective layer is laid under the waterproofing membrane to ensure the integrity and damage of the waterproof and bright resistant layer. The protective layer can be made of crushed stone, cement mortar, protective film and other materials. On top of the protective layer, local green plants, flower beds and other decorations can be carried out, and facilities such as solar water heaters can also be directly installed.

The practice of the upper level is that the upper level uses double-layer waterproofing membrane, and the waterproof material mainly uses polyvinyl chloride (PVC) waterproofing membrane and self-adhesive waterproofing membrane. The two-layer waterproof membrane adopts the method of lap welding, which is laid smoothly and has no wave phenomenon. A layer of isolation layer is laid under the waterproof layer to play the role of sound insulation, heat preservation, fire prevention and so on.

Laying a protective layer under the isolation layer is the same as at the non-human level. On top of the protective layer, local green plants, flower beds and other decorations can also be carried out, but it is necessary to pay attention to the damage of plant growth to waterproof materials. It should be noted that in order to ensure that the roof is resistant to spring water, it is recommended to find a professional waterproof construction team or design agency for design and construction.

At the same time, roof maintenance and inspection are also necessary, especially in climatic conditions such as heavy rain and storms, and it is necessary to pay more attention to the safety and waterproofing of the roof.
