Description
Technical Field
The application relates to the field of building construction, in particular to a deformation joint-free high-low crossing entrance node structure with low inside and high outside of a concrete flat roof.
Background
At present, a public building generally lifts a staircase out of a roof, a local room or a local building layer protrudes out of the roof and is communicated with a building roof; in addition, the frequency of use and the requirements of people on roofs are also higher and higher, and when civil building engineering design is carried out, almost every single building project has a local layer or a local room protrudes from a roof. Particularly in medium and high-rise residential projects, it is more common to raise stairwells to the roof, while arranging equipment rooms on the roof level. Therefore, it is important to highlight the connection node of the entrance and the exit of the building part of the building roof, which is communicated with the outdoor roof.
During building design, the elevation of a structural top plate of a roof is generally consistent, if a local building room protrudes out of the roof, the thickness of a floor surface layer in the protruding local building room is generally only 50mm-100mm, and the thickness of an adjacent outdoor roof (the finish surface of each material layer) is generally 230mm-250mm at the thinnest part of the roof under the condition of a roof insulation board, then a slope is found towards an entrance threshold, the highest point of the roof finish surface is located at the entrance threshold in a map set, and the distance height requirement of the highest point from the bottom of the door is generally not less than 350mm, so that a large height difference occurs between the adjacent outdoor roof surface layer and the floor layer in the building. If the structural elevation of the floor slab of the part partially protruding the roof is consistent with that of the top plate of the outdoor roof in design: taking the distance between the threshold of a building entrance and a building exit and the lowest point of a finished roof surface as an example, the roof slope is considered according to 2%, so that the difference between the inside height and the outside height of the indoor entrance and the outdoor exit of the roof can reach 0.8 m.
For the access node practice, the conventional node practice is selected, such as page a17 in the national building label design atlas 12J201 flat roof building structure; and page A14 of 12 series building standard design province map set 12J5-1 flat roof, all of which introduce references to two roof entrance and exit design nodes with and without deformation joints between the building part of the protruding roof and the outdoor roof. The utility model mainly describes that the indoor exit and entrance node is lower than the outdoor roof without deformation joints. The provincial mark atlas is a method for making the nodes of the entrance and exit without deformation joints have indoor surface layers higher than the finished surface of the outdoor roof; the method for enabling the national standard map set to approach the node is to utilize two steps to 'trisect' the entrance-exit height difference between the height difference of an indoor floor slab and the threshold, wherein the first two steps are made of C15 plain concrete, each step is 240mm in width, the third step is directly stepped into the threshold from the second step, and the width of the third step is only the width of an outer wall at the threshold. The method is characterized in that the width of each step of the step is slightly small, particularly the height of the step is too large, most importantly, the connection processing between the entrance and the threshold is too compact, when the entrance and the threshold pass through the threshold in use, the entrance and the exit need to directly fall to a roof under the condition of no buffer, the entrance and the exit do not have good connection processing at the highest point of the entrance and the threshold, and a good buffer space is designed.
At present building roof, as the place of taking refuge, leisure and activity temporarily conflagration, under the condition that its utilization ratio is higher and higher, the access & exit node that conventional atlas introduced, because indoor linking was marked time too narrowly too high during the design, when passing threshold department moreover, can pass through and not have the roofing immediately after the buffer space, and the people can be very careful when passing through, and it is very uncomfortable to pass. Especially, when a fire disaster occurs, when people escape, safety accidents such as treading and the like caused by stepping or tripping are caused because the design of the entrance and exit is compact and no consideration is given to designing a buffer space at the doorsill.
Therefore, the design of the conventional roof entrance and exit node only ensures the design completeness of the node, only refers to or is close to the minimum numerical requirement on the specification in the design of entrance and exit tread width and tread height, and is actually deviated from the basic ergonomics, so that the node is inconvenient and uncomfortable in the process of usual personnel passing or equipment conveying. In extreme cases, there are even great safety concerns.
