The temperature difference between day and night, uneven settlement, and deformation caused by earthquakes. If it is sufficient to cause damage to the building structure, it should be cut off the entire building in advance in the deformation sensitive part or other necessary parts.Each part becomes an independent unit, or it is divided into simple, regular, independent sections, and makes the seams between each section reach a certain width to meet the needs of deformation, which is called ground deformation seam.
Ground deformation seam settings
The main points of the ground deformation seam settings are as follows: 1. The fire door located near the deformed seam should be located on the side with a large number of floors, and the door should not cross the deformation seam after the door is turned on.2. The special product produced by the factory should be selected from the ground deformation seam material. Its structure can be referred to the finished metal deformation seam device in the "Transformers Architecture (3)" (04CJ01-3).3. When the ground deformation seam is required, the fire blocking zone should be configured in the deformation seam.4. When there is a waterproof requirements for the ground deformation seam, the finished metal deformed seam product equipped with water -proof glue strips should be equipped in the deformation seam.5. For the ground with high requirements for preventing noise, you can choose a product with rubber embedded strips.
Ground deformation seam price
The price of ground deformation seams is generally 95 yuan/meter.
Ground deformation seam specification
The deformation seams of the building ground shall be set according to the design requirements, and the provisions of the construction specifications shall be compared with the construction specifications: 1. The deformed seams include telescopic joints, sedimentation and shock -proof joints.All of the above seams should be consistent with the position corresponding to the structure, and the structure layer of the building floor should be penetrated. The width of the seam should not be less than 20mm.2. The deformation joints on the ground floor should be set separately according to extension, joints and sedimentation seams.(1) When the outdoor ground engineering uses cement concrete cushion, an extension should be set, and the distance is generally 30m.The width of the extension is 20 ~ 30mm, which is connected up and down.Fill asphalt materials in the sewing.(2) The cement concrete cushion of indoor and outer ground should be set up with vertical and horizontal seams.The layout of the joints is dependent on the construction direction of concrete.(3) The structure and spacing of the joints are related to the conditions of the use of cement concrete cushion and the temperature of the construction environment, and the technical requirements of the cement concrete cushion seam shrinkage.
Ground deformation sewing construction
First, the tools required for construction First, I will introduce the preparations before construction.First of all, the tools we need are impact drills, pistol drills, screwdrivers, hammer, thread pendants, saws, steel rolls.The materials we need are 401 glue, plastic swelling tubes, steel plates, galvanized iron lids, 20 thick rock wool plates, 5 layers, anticorrosive coatings, wooden screws, and so on.Second, construction operations are next, and after preparing the tools, we must start operation.In the first step, we must first clean the impurities of the deformation seam.At the same time, it is necessary to polish the sides of the deformed seams smooth and flat. There is a bumpy place that needs to be filled or cut off. Its verticality must be satisfied with the design requirements.You should also check whether the processing size is accurate.Next, you need to put the galvanized iron cover on the ground, while ensuring that the ground is closely combined with the galvanized iron cover.
