Abstract
The utility model discloses a prefabricated assembled type open-web net rack for reinforced concrete. The prefabricated assembled type open-web net rack comprises rectangular prefabricated frame members and is characterized in that the rectangular prefabricated frame members are connected and spliced to form an integral net rack via nodes A (1), nodes B (2) and nodes C (3), and connections among the rectangular prefabricated frame members and the nodes A (1), the nodes B (2) as well as the nodes C (3) are realized by welding. The prefabricated assembled type open-web net rack is simple, convenient, safe and reliable to operate, engineering quality can be ensured, and mounting time can be obviously shortened; manual work is saved by 30% as compared with a traditional construction method; a great amount of frameworks can be saved; construction time for internal and external decorations is shortened, and time for completion can be shortened; on-site wet construction is basically avoided, construction waste is reduced by about 70%, construction water is saved by about 50%, noise pollution is greatly lowered, and advantages in energy conservation and environment protection are obvious. Stress on the integral open-web net rack is more reasonable, shear stiffness of a structure is further improved, node reinforcement structures are improved, and steel is further saved.
Description
Technical field
The utility model belongs to building field, particularly relates to a kind of prefabricated assembling type reinforced concrete hollow rack.
Background technology
Steel concrete hollow rack structure, it is the novel building structural system of roof growing up in 20th century, by steel concrete Vierendeel truss intersect form two to or three-way latticed grid structure, form building roof system with armored concrete slab (roofing can be used glass to improve lighting efficiency), this structural system is compared and is had from heavy and light with normal reinforced concrete beam plated construction, applicable span is large, compares the feature that has Maintenance free with steel work.Form of construction work can adopt cast-in-place or prefabrication and assembly construction.And a large amount of template of prefabricated assembling type reinforced coagulation hollow rack saving, accelerating construction progress, improves civilized construction degree.
Summary of the invention
The purpose of this utility model is to provide a kind of prefabricated assembling type reinforced concrete hollow rack, this structure is spliced at the scene by prefabricated square shape framework, save a large amount of templates, accelerated construction speed, improve civilized construction degree, and whole hollow rack is stressed more rational, has further improved the shear stiffness of structure, and improved node arrangement of reinforcement structure, further saved steel.Be applicable to span 22-48m span building roof system.
The purpose of this utility model and to solve its technical problem underlying be to come by the following technical solutions
Realize: a kind of prefabricated assembling type reinforced concrete hollow rack, comprise a plurality of hollow framework prefabricated components unit, hollow framework prefabricated component is by node first 1, and node second 2 and node the third 3 is connected the whole rack of assembled formation; Being connected of hollow framework prefabricated component and node first 1, node second 2 and node the third 3 all adopts welding.
The utility model compared with prior art has obvious advantage and beneficial effect.From above technical scheme, the utility model is easy and simple to handle, safe and reliable, can guarantee workmanship, and the set-up time significantly shortens, than conventional construction method saving artificial 30%; Can save a large amount of templates; The internal and external ornament duration is short, and time of completion can shorten; Substantially avoid situ wet operation, reduce building waste approximately 70%, save construction water approximately 50%, reduced in a large number noise pollution, with the obvious advantage aspect energy-conserving and environment-protective.And whole hollow rack is stressed more rational, has further improved the shear stiffness of structure, and improve node arrangement of reinforcement structure, further saved steel.
