System and its implementation.
Background technology
Building industrialization is the important development trend of current China's building field, is also the hair that country carries forward vigorously and supported
Open up direction.Prefabricated construction is the product of building industrialization, and fast with construction rhythm, good product quality, estimated cost are low,
Efficiency of construction is high, the advantage such as simple production process.Assembled architecture is typically characterized by simplified site operation work, significantly
Shorten the site operation duration, its core seeks to reduce work on the spot amount, particularly influences the work of crucial duration.
Traditional steel construction uses frame beam column system always, steel construction prefabrication, on-site consolidation, and floor is using cast-in-place
Floor, though traditional steel construction substantially falls within assembled architecture, has that Site Welding workload is big, rod member quantity is more, existing
Floor is poured from great, the construction period is long, it is the problems such as cost is higher than normal concrete structure, quick, economical away from industrialized building
Core, actual accounting share is relatively low in whole building engineering so far.
For problem present in above-mentioned existing engineering, the present invention proposes a kind of new multi and tall steel building assembled group
Structural system is closed, using L-shaped truss steel column as the bearing carrier of vertical direction and horizontal bending resistance component, one in work progress
Secondary lifting, without setting temporary support.Change traditional form that is rigidly connected on beam, truss column connected node, use high-strength spiral shell instead
Tether and connect, so as to save a large amount of welding jobs, substantially reduce the duration.Floorboard uses the form of prefabricated superimposed sheet, both can be real
The prefabrication and assembly construction of existing system, while ensureing that structural system has preferable globality.System exterior wall uses assembled cladding panel
System, convenience quick for installation.New steel structure assembled combined structure system overcomes the deficiency of traditional steel construction, realizes steel
Quick, the economic advantage of structural construction, is to be manufactured in plant produced by the most of program simplification of construction site, is reduced pair
The influence of site environment, improves building products quality, reduces building cost, embodies the basal core of building industrialization, can be with
The extensive use in multi-rise building structure.
The content of the invention
A kind of new multi and tall steel building assembled is provided the present invention seeks to the defect existed for prior art to combine
Structural system and its implementation.
The present invention is achieved through the following technical solutions：
By prefabricated L-shaped truss steel column as the bearing carrier of vertical direction and horizontal bending resistance component；In truss leg level
Direction sets overhanging beam section, is attached with girder steel with bolt；Floorboard uses prefabricated reinforced concrete superimposed sheet, and prefabricated board leads to
Peg is crossed to be connected with girder steel；The cast-in-place concrete surface layer on the prefabricated board completed, each purlin is cooperateed with by assembled integral floorboard
Frame steel column cooperation；Exterior wall uses external hanging type prefabricated panel, removes the work of live external decoration from, thus formed beam, post, plate,
Wall highly prefabricated assembled combined structure system.
It is L-shaped in described L-shaped truss steel column, horizontal layout, in the vertical direction is with horizontal web member and diagonal web member
Truss form, L-shaped truss steel column can be processed in factory, be determined on the premise of structure and movement requirement is met by calculating
The width and length of each section steel truss wall column.Truss steel column is welded with the built-in fitting in basis at the scene, without interim
Support can reach stable state.
Described L-shaped truss steel column sets overhanging beam section in the horizontal direction, and overhanging beam section section is I-shaped, overhanging beam
The height of section is the half of pre-manufactured steel depth of beam, in the horizontal direction spaced set ribbed stiffener, in overhanging beam section equidistantly
Symmetrical prepared screw-bolt hole.
Described prefabricated girder steel, makes overhanging section of variable cross-section at beam two ends, overhanging section of section of variable cross-section be it is I-shaped, it is prefabricated
Overhanging section of variable cross-section is made at the two ends of girder steel, and the height in overhanging section of section of variable cross-section is the half of prefabricated girder steel whole height, with
The overhanging beam section of steel column is symmetrical arranged ribbed stiffener and bolt hole, during site operation directly by prefabricated girder steel two ends variable cross-section overhanging section take
On truss steel column overhanging beam section, it will be attached after ribbed stiffener and bolt hole consistency from top to bottom with high-strength bolt.
Described Shear Behavior of R. c. Laminated Slabs, concrete uses lightweight concrete, and reinforcing bar uses triangular truss muscle, prefabricated
The thickness of plate is 80-120mm, in floor two ends prepared screw-bolt hole, is directly ridden over plate on girder steel during site operation, and with high-strength
Prefabricated board and girder steel are attached by bolt by prepared screw-bolt hole.It is existing in casting concrete above after the completion of prefabricated board laying
Surface layer is poured, each truss steel column cooperation is cooperateed with by assembled integral floorboard.
Described prefabricated panel, can be according to requirement of engineering in prefabricated, the side pulled up at the scene by lower branch of progress of factory
Formula is attached with steel frame.
It is an advantage of the invention that：Truss steel column, girder steel, floor, wallboard can plant produced, on-site consolidation, construction is fast
Victory is convenient.Truss steel column replaces once to be lifted in traditional single-column, work progress, without setting temporary support, prefabricated girder steel and
Truss leg is connected with, and reduces the cumbersome workflows such as welding, and assembled integral floorboard cooperates with each truss steel column to be total to
With work, the prefabrication and assembly construction of system can be both realized, while ensureing that structural system has preferable globality, system exterior wall is adopted
With assembled cladding panel system, convenience quick for installation.
