Abstract
The utility model relates to the technical field of building engineering, in particular to a totally-prefabricated frame steel supporting shear wall structure. The totally-prefabricated frame steel supporting structure comprises a prefabricated frame, a steel support and embedded parts. The prefabricated frame is arranged in the position, where a cast-in-place shear wall needs arranging, in a high-rise frame structure; the steel support is arranged in the prefabricated frame and is connected with the prefabricated frame through the embedded parts. Because a totally-assembled frame-steel support structural system takes the place of a frame-shear wall system needing cast-in-place, total prefabrication assembling of a high-rise frame structural component is achieved. Prefabrication assembling rate of components of the high-rise frame structure is improved, and the building industrialization technology of the high-rise frame structure can be developed.
Description
Technical field
The utility model relates to construction engineering technical field, specifically a kind of full precast frame steel support shear wall structure.
background technology
Industrialization of construction industry can energy-saving and emission-reduction, protection of the environment, raising construction quality, reduce builing industry cost of labor, alleviate the construction worker labour intensity, to shorten the construction period be the main direction of builing industry upgrading and transformation.The prefabrication and assembly construction of building structure is the fundamental technics of industrialization of construction industry.
Choose reasonable fabric structure system is the important content of design prefabrication and assembly construction building, is also one of technology realized the industrialization of construction industry most critical.
According to current domestic current standard, the prefabrication and assembly construction frame system is multiplex in many rooms building.For highrise building, frame construction generally need be set up some shear walls as main lateral resistant member.But current specifications requires shear wall must adopt the poured in place concrete construction.So, to adopting the building of Frame _ Shear Wall Structure system, realize the prefabrication and assembly construction of the entire infrastructure members such as wall, post, beam, plate, under the constraint of current specifications, be infeasible.In view of the foregoing, whole prefabrication and assembly constructions of high-rise frame structure are restricted, and the prefabrication and assembly construction rate reduces, and has restricted application and the development of this type of structural construction industrialization technology.
Pure frame structural system is multiplex in many rooms building.For highrise building, frame construction generally will be set up some shear walls as main lateral resistant member.But current specifications requires shear wall must adopt the poured in place concrete construction.
Be subject to the restriction of domestic current standard up till now, to adopting the building of Frame _ Shear Wall Structure system, frame construction generally will be set up some shear walls as main lateral resistant member.But shear wall must adopt poured in place concrete.Therefore can't realize whole prefabrication and assembly constructions of the structural element such as wall, post, beam, plate.The prefabrication and assembly construction rate reduces, and has restricted application and the development of this type of structural construction industrialization technology.
The utility model content
The utility model utilizes framework-steel to support the replacement shear wall, has avoided the specification limits of shear wall palpus poured in place concrete construction.Substituted the framework-shear wall system that needs part cast-in-place, and then realized whole prefabrication and assembly constructions of high-rise frame structure member by the framework of full assembling-steel support structure system.Improved the prefabrication and assembly construction rate of this class formation, the industrialization of construction industry technology of high-rise frame structure is developed.
Concrete technology contents of the present utility model is: a kind of full precast frame steel support structure, comprise that precast frame, steel support and built-in fitting, wherein, in high-rise frame structure, need the position that cast-in-place shear wall is set that described precast frame is set, steel is set in described precast frame and supports; Described steel support with precast frame between with built-in fitting, be connected.
Described precast frame comprises that prefabricated frame trestle and prefabricated frame set a roof beam in place.
Described steel supports and is connected into the chiasma type central steel by two steel weldings and supports, described chiasma type central steel support with described built-in fitting between by rivet, be connected.
Beneficial effect:
1, support and substitute cast-in-place shear wall with framework-steel, both met the requirement of current specifications, realized again needing to adopt whole prefabrication and assembly constructions of framework-shear wall architecture;
2, alleviate dead load, and then reduced seismic load and basic expense;
3, steel supports as main anti-dynamometry member, due to detachably, after shake, can upgrade, and is convenient to shake rear recovery.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of full precast frame steel support shear wall structure of the utility model;
In figure: 1-prefabricated frame trestle; The 2-built-in fitting; 3-chiasma type central steel supports; The 4-prefabricated frame is set a roof beam in place.
The specific embodiment
As shown in Figure 1, a kind of full precast frame steel support shear wall structure, the position that needs to arrange cast-in-place shear wall in high-rise frame structure arranges the framework of cast-in-place shear wall, a chiasma type central steel is set in described framework and supports; Wherein said chiasma type central steel supports between the framework with cast-in-place shear wall and is connected with built-in fitting.
Described chiasma type central steel support with described built-in fitting between by rivet is dismountable, be connected.
The utility model arranges in the Frame _ Shear Wall Structure system of cast-in-place shear wall and supports and substitute cast-in-place shear wall with framework-steel at needs, and then has realized whole prefabrication and assembly constructions of such structural system.
The Specific construction step is: the first step, by the current specifications requirement, carry out structural design analysis, determine that described precast frame, steel support and the specification of built-in fitting;
Second step, when being provided with precast frame that steel supports and carrying out prefabrication, by connecting nuzzle in advance described prefabricated frame trestle and prefabricated frame of built-in fitting that steel supports, set a roof beam in place.
The 3rd step, the position that needs to arrange cast-in-place shear wall in high-rise frame structure arrange the chiasma type central steel and support, described chiasma type central steel support with described precast frame between with built-in fitting, be connected;
Further, before described the 3rd step, wait frame column, Vierendeel girder and the floor hoisted in position of whole layer, after superimposed in-situ layer is built, then be hinged with the support of chiasma type central steel.
Support and substitute cast-in-place shear wall with precast frame and steel, both met the requirement of current specifications, realized again needing to adopt whole prefabrication and assembly constructions of framework-shear wall architecture.
Alleviate dead load, and then reduced seismic load and basic expense.
Steel supports as main anti-dynamometry member, due to detachably, after shake, can upgrade, and is convenient to shake rear recovery.
