Status and development of core mold structure design for hollow floor
进武空心楼盖提供空心楼盖芯模架构设计的技术现状与发展,从三个方面进行阐述,分别从应用前景,问题分析,以及空心楼盖芯模与软件的配合使用三个方面描述. Description: Jinwu Hollow Floor Slab provides the technical status and development of hollow core mandrel architecture design. It is described from three aspects, including application prospects, problem analysis, and the use of hollow core mandrel and software. description.
The technical status and development of hollow core mandrel structure design can be talked from three aspects.
1. Extensive application of core mold for hollow floor
In a museum in Guangdong, we do a design project. The construction project is special, and the others are different. The floor of the construction project is inclined and the height difference is about 5 meters. The span is also relatively large and very complicated, ranging from 8 meters, 9 meters, 10 meters, 12 meters, 14 meters, 18.75 meters, which makes our engineering painstaking. The most important thing is that the plane is irregular. Party A recommends the use of steel structure, so the construction requirements are relatively stable, but the investment is large, the steel structure is more complex, and the weight is heavy. Finally, we discussed with our engineering team to use a hollow floor core mold because our hollow floor core mold is light in weight. And convenient, and finally won the praise of customers.
Our other construction site is in a high-rise building in Chongqing. We also used hollow core slab core molds. The construction site has 54 floors, 223 meters in height, and a maximum span of 11 meters. At the same time, we arranged two shifts to work together to change the floor height from 0.9m to 0.7m. At this time, we set their total weight to be the same as the original. At this time, we calculated when communicating with Party A. After using the core mold of the hollow slab floor, the use space was improved, and the amount of reinforcing steel was reduced.
In large-span structures, the hollow core slab core mold can be used at 8 meters and 9 meters in general engineering. When using steel beams, it is the most economical time to rebar, and do prestressed beams. It can be seen that the core slab of the hollow floor has strong technical advantages.
At present, there are many core mold works for hollow floors in China, including engineering renovation and reinforcement. This work has also been done for many years. The structure has been capped, but it has not been used. Party A can ask for processing design. The core mold of the hollow floor has been developed until now, and there are a large number of engineering models every day. Learn the pulse of the industry at Wuhan Jinwu hollow floor . It is even more numerous.
2. Analysis of design problems existing in the core mold structure design of hollow floors.
After so many years of development of hollow core mandrels, the development of technology has improved a lot, especially in the aspect of civil air defense, but there are also problems. In the face of problems, we often put them in the hands of construction engineers and let them detail Give descriptions and principles, and put them out, so that the problem will be more miniaturized, such as anti-floating problems, we have all spoken out, communicated, and finally solved.
Hollow core mandrel is an industrial chain. This industrial chain is very related to the structural design of hollow core mandrel. How to use hollow core mandrel in construction works well and cost-effectively. In the end, Party A is satisfied. This is the key point. The most important point is that after applying the hollow core mandrel to the construction, the construction and Party A units can accept the hollow core mandrel product in many aspects. It is also a problem that everyone has a headache.
Let's take a Shandong project as an example. This question is asked whether it is reasonable? In this project, the engineer made a concealed beam, and the concealed beam was another edge. Is this method feasible? The concealed beam was set to a width of 0.6m at the time. He found that the problem of length calculation was not taken into account. His thoughts, like many others, are derived from the early hollow core mandrel. It's just that this dark beam is too wide, it is not necessary. He is characterized by a large edge and a small span. These are minor issues that have not been fully reflected. This project can be done. If another project knows that the thinking is wrong, it will easily cause the collapse of the project. The structure here is a beam. He borrowed it from countless small beams. There is no need to redistribute beams. It is meaningless to redistribute beams. And it is a waste, which is very impractical, so we need to apply different hollow floor core mold solutions according to different projects.
There are also some technical problems in the core form of the hollow floor slab. The two widths of the core slab of the hollow floor are 6 cm, but the concrete is between 2.5 and 3 cm. This is obviously too narrow to meet the data requirements of a beam. At the time, we needed to rebuild. We found the engineering aspect to communicate. The construction project pointed out that for the dark beam, the dark beam can be 600 wide, but a solid band was placed beside the dark beam. At that time, we designed the width of the dark beam. It is between 900 and 1 meter. The two beams were 1 cm between them, so small that they were too small for the project to do. If we finally choose to make the total width 400 and then add it from 6 cm to 15 cm, this beam will be very effective.
The core of the hollow floor is properly used, and the steel bars are really saved. After the savings, the potential and role of the steel bars will be further fully used. In this project, the designer sent me the standard to achieve an 8m column span.扥 Case, make a mirror beam + column cap, and finally the other works to make the core mold of the hollow floor of 2m to 3m is too large and unsuitable. After being put forward explicitly, the design scheme was also improved.
3.Hollow floor core mold structure design and use with STRAT software.
First statement: STRAT is not a professional software for hollow core mandrels, strat is a large-scale engineering software, can you understand the large level? Large-area calculations such as gymnasiums, space technology, etc. can be used for calculations. Three-dimensional graphics are also much more convenient than AutoCAD.
If you want to make a graphics board, divide it into 100,000 or 200,000. Basically, the results are calculated in half an hour. The calculation speed can reach more than 10 times that of PKPM and about 20 times that of Guangsha. 3-5 times, strat software is currently the fastest earthquake analysis software. STRAT software is the carrier of force island design theory.
While using the software well, it needs to be combined with the actual project.The project is different.Although the software is used well, it is not conducive to feasibility.The use of the final core of the hollow floor slab needs to be carried out according to actual standards in case of emergencies , Safe production, I hope that everyone can use the software and improve the quality of the project.
