Gymnasium/Swimming Pool Roof Solutions

Engineering characteristics


1.Safety requirements are extremely high,as a public building,must choose the safest structure form.Must have the certain ability to resistance natural disaster,like the snow,the earthquake.

2.Beautiful appearance is required. Many stadiums and gymnasiums have become local landmarks after being built.

3.Large span ,but the usage of the building requires less internal column and more cantilever structure, it is disadvantageous to the safety of structure.

4.Strong durability,long service life,minimal maintenance of the structure (maintenance cost is too high).

5.Construction period is long,site welding is difficult to ensure the quality,it has higher safety hazard.

Swimming Pool 

1.Good wind resistance,snow resistance,seismic performance,high stiffness,high structural safety.

2.Large span,20 meters ~70 meters are easy to realize .

3.High degree of factory production,80% of the workload is factory based which is accord with the characteristics of national prefab building.

4.Easy to install,as long as it has the crane.

5.Short construction period,500~1000 square meters can be installed in one day.

6.All kinds of three-dimensional modeling can be implemented.

Application area

1.The basketball court space frame

2.The badminton court space frame

3.The tennis court space frame

4.Indoor football pitch space frame

5.The bullring space frame  

6.The swimming pool space frame

7.The arena space frame

8.The stadium space frame

9.The university gymnasium space frame

10.The exhibition hall space frame


The roof of the gymnasium requires large span and large space,as well as good wind resistance,snow resistance and seismic performance,especially high safety performance. The space structure of BJMB caters to this characteristic,so the space frame structure of BJMB in the gymnasium we built accounts for more than 80% of the overall quantity.

1.BJMB structure has multiple statically indeterminate characteristics ,good internal force automatic distribution and adjustment,It’s currently the safest type of all structural systems.Excellent performance against wind ,snow and earthquake.

2.It can achieve a variety of modeling,it is beautiful and generous.

3.the structure itself can achieve a long span,can use professional software for the optimization of column points and make the safest layout.

4.It can be designed according to the safety of use in 50 or 100 years. Once built,reliable anti-corrosion can reduce the maintenance work as much as possible.

5.For the structure,only bolts should be installed on site,so that the construction period can be shortened a lot,the installation quality can be high,and the safety risks can be reduced as far as possible.

6.Low overall cost,high cost effective,good control of total cost and total cost in the probation period.

7.In China,BJMB structure is used for schools and public buildings. It is used for the settlement of victims after earthquake or natural disaster.The structure will not be damaged by earthquake and strong wind after the design safety level is reached.Sturdy and safe.For example,a large area of membrane roof,it is recommended to use welded pipe truss structure.

process description

1.Attention points in stadium space frame design:

The importance coefficient of the structure must be amplified according to the use requirements,the natural disasters may encounter ,even if there is no requirement,also at least to be enlarged to 1.15-1.2 (specification requirements,but also have other considerations).

(1)More possible combinations are considered in load combinations,even those with less influence;

(2)Pay attention to the lower chord hanging lamps,maintenance of the horse road,suspended ceiling load,but also to consider the possible in the future may appear in the place of concentrated suspension load.

(3)Component calculation of strength should be more conservative and more safety,to consider and to enlarge any possible hazards ,It shouldn’t be discount because of the economy or the uncertainty of safety hazard.

(4)We should have an anticipation against wind,snow,earthquake and other extreme weather Ensure the safety of natatorium space frame from the design source!

2.Production process: Comprehensive factory quality control must be carried out on materials,processing,welding and other aspects to ensure the quality of components.After the self-inspection,the material must be processed and checked by a third party again. After the processing,the material must be subjected to destructive inspection in the laboratory to ensure that the component quality is excellent before leaving the factory.

3.Installation process: The installation quality is related to the safety of later use. For large stadiums,we suggest skilled Chinese workers to install them.Local workers are not recommended to undertake the installation of the main part,except for the roofing and other non-important parts .After installation,we will check and eliminate the possible hidden danger to ensure safety before use.
