Honeycomb core hollow floor structure requirements
进武空心楼盖提供武汉蜂巢芯空心楼盖构架的基础要求,从七点进行分析,其中第2点,又分为4点进行分析,第3点又进行3点分析来完成提供蜂巢芯空心楼盖的架构安全. Description: Jinwu hollow floor provides the basic requirements for the Wuhan honeycomb core hollow floor structure. It is analyzed from seven points, of which the second point is divided into 4 points for analysis, and the third point is further analyzed for 3 points to complete the honeycomb. The core hollow floor is structurally secure.
Honeycomb core hollow floor-general structural requirements:
1: The height of the rib web of the honeycomb core hollow floor must be less than eight times the rib width, and the value of the rib width ranges from 70 to 150 mm.
2: The principle of determining the thickness of the honeycomb hollow hollow floor slab of the honeycomb core hollow floor must follow the following 4 points:
2.1: Frame dark beams hive 砼 empty web floor, the thickness of the hollow floor slab is determined by the height of the dark frame beam, the value range is 0.04 of the beam span.
2.2: The frame exposed beam honeycomb 砼 empty web floor, the thickness of the hollow floor cover is 1/38 of the short side length to 1/30 of the short side length.
2.3: The prestressed honeycomb core hollow floor slab of the honeycomb core hollow floor can be designed to apply a certain amount of prestress in the frame beam, or the rib of the frame beam and the hollow core slab hollow core of the honeycomb core can be applied at the same time. Generally, the thickness of the prestressed honeycomb cymbal empty web floor slab can be increased by 1/10 of the short side length of the original honeycomb cymbal empty web slab thickness.
2.4: If there is a large local load or civil air defense project, we need to determine the thickness of the plate according to the actual situation.
3: When the honeycomb core hollow floor of the honeycomb core hollow floor requires openings.
3.1 When the size of this hole is not greater than .03 * 0.3m, the truncated steel bars need to be replenished around the hole and no special calculation is required;
3.2 When the size of this hole is greater than 1m, or even the ribs of the hollow slab of the honeycomb core hollow floor of the honeycomb core are cut off, then we need to set side beams or profile steel around the hole to make up the board weakened by the hole Or section stiffness of ribs;
3.3 When the size of this hole is between 0.3 and 1m, it shall be determined separately according to the actual force situation.
4: When calculating, when the shear force of the frame flat beam does not meet the strength requirements in the design, the hollow floor plate of the column cap area can be made into a solid plate, and the corresponding structural steel bar is added at the same time.
5: When the slab panel of the honeycomb core hollow floor part has a large-diameter pipeline, at this time, measures such as reducing the height of the honeycomb core hollow floor or setting a groove in the top plate of the honeycomb core can be taken to solve the problem.
6: The basic requirements of the hollow core of the honeycomb core 砼 The strength level needs to be not less than C30.
7: The board surface of the honeycomb core hollow floor of the honeycomb core hollow floor slab should be equipped with a two-way steel mesh. Its diameter ranges from 4mm and its spacing is <300mm.
Based on the above 7 points, the application of the honeycomb core hollow floor in the building is much more convenient.
