Description
Technical Field
The utility model relates to an assembled structural system, especially an assembled house that is suitable for high-rise steel construction.
Background
The traditional assembled house with high-rise steel structure has the following defects:
in the main structure:
firstly, for an assembly type steel structure building, particularly an assembly type steel structure house, the problem of indoor exposed beams and exposed columns cannot be avoided by adopting the conventional beam column cross section such as an I-shaped cross section or square steel pipe concrete.
And secondly, a structural outer frame is arranged at the position of the outer enclosure wall, and if the height of the windowsill of the outer enclosure adjacent to the empty space is less than 800mm and the residence is 900mm, protective measures such as railing handrails should be taken. In practice, in order to omit the arrangement of protective measures, the height of the vacant windowsill is often required to be higher than 800mm, and the height of the house is 900 mm. However, based on the requirements of lighting or windowing rate of the building outer wall, the outer frame steel beam often needs to be turned over to meet the requirements of the aforementioned building specialties, that is, the elevation at the top of the steel beam is raised, and the bottom surface of the floor slab is no longer supported at the top of the steel beam.
In the existing upper reverse steel beam, the floor slab is supported by the flange plate close to the full length of the neutral axis of the steel beam, and in the upper reverse structure, the flange plate close to the full length of the neutral axis of the steel beam has very limited contribution to the bending resistance of the structural beam, mainly plays a role in supporting the floor slab, and has low material utilization rate.
In the anti-pendant system:
the requirements of wind resistance and earthquake resistance of the three-story and multi-high-rise assembled steel structure building are self-evident, and the structural arrangement of a lateral force resistance system is the key. The traditional steel support member is combined with a steel frame structure, although the whole lateral resistance efficiency is better, the steel support member is used for residential buildings, is not easy to coordinate with door and window openings (particularly on a structural outer frame) in the buildings, and becomes one of pain points for lateral force resistance arrangement of a high-rise steel structure.
The anti-buckling ductile wallboard is simple in arrangement, can be flexibly connected with a door and window opening only by being connected with the upper frame beam and the lower frame beam (not connected with the column), is proved to be an excellent lateral force resistant member in performance, overcomes various defects of other types of ductile wallboards (such as unsatisfactory wind vibration comfort degree of a pure steel plate shear wall, complex installation and construction of a combined steel plate shear wall and uncontrollable quality), has good market reaction and high acceptance. Generally, the buckling-restrained ductile wall panel is composed of precast concrete cover plates at both sides and embedded steel plates, the embedded steel plates are connected with upper and lower frame steel beams, and the precast concrete cover plates at both sides are separated from the structure and are only used for restraining the out-of-plane buckling of the embedded steel plates.
In particular, the thickness of the embedded steel plate of the concrete cover plate is several times of the thickness of the embedded steel plate in order to effectively inhibit the out-of-plane buckling of the embedded steel plate due to the fact that the precast concrete cover plates on two sides are large in volume weight and not high enough in strength.
And fourthly, the connection between the frame beam and the frame column requires the joint rigidity of the beam column to provide the lateral rigidity resistance of the main structure, the division of labor of the steel frame and the anti-buckling ductile wallboard is unclear, the steel frame not only bears the vertical load, but also participates in resisting the horizontal load, and the anti-buckling ductile wallboard is not only used for resisting the horizontal load, but also bears the vertical load. The node rigidity is not beneficial to reducing the steel consumption of the main structural frame and field welding work, the method of providing the lateral stiffness by utilizing the node rigidity of the steel frame is not cost-effective, and the ductility of the rigid node of the steel frame is low.
Fifthly, the steel plate shear wall does not bear vertical load, which is one of the design concepts, the requirement is common in the anti-seismic design specifications of Europe, America and the like, and the common measure is to finish welding or bolt final screwing of the wall plate and the peripheral frame after capping of the main structure and most of the vertical load are applied, and the wall plate and the peripheral frame are temporarily fixed before the capping and most of the vertical load are applied.
But the construction period of a high-rise structure in China is tense at present, and the delayed installation of the steel plate shear wall is difficult to achieve in practical engineering. If the welding or bolt final screwing of the embedded wallboard and the peripheral frame is synchronous with the main structure, the excessive pre-pressure generated on the wallboard by the whole compression deformation of the main structure is often worried to be unfavorable for the counterside.
According to the specification of JGJ-T380-2015 No. 3.1.3 of the technical specification of the steel plate shear wall, the steel plate shear wall is designed and calculated according to the condition that the steel plate shear wall does not bear vertical loads, and corresponding construction and construction measures are adopted to realize calculation assumption.
In a floor system:
sixth, at present, the floor form of the fabricated steel structure building comprises a laminated slab, a profiled steel sheet composite floor, a steel bar truss floor bearing plate and the like, and no formwork is required for floor construction. The 'steel bar truss floor bearing plate' completes the workload of reinforcing steel bars of most floors in a workshop in advance, so that the construction is simpler, more convenient and quicker, and the steel bar truss floor bearing plate becomes one of popular floor application forms of the current assembly type steel structure building.
However, although the advantage of the steel bar truss floor support plate in the construction stage is obvious, a lot of problems which are not easy to process are brought to the subsequent decoration and finishing operation, for example, if the bottom die (usually galvanized steel plate) of the steel bar truss floor support plate is not removed or processed, residents often cannot accept the light reflection effect of the bottom die steel plate of the ceiling, so that the ceiling is hung or covered with a thin plastering system.
For a large number of common houses, the ceiling is more common and economical without hanging the ceiling, so that a thin plastering system is usually hoped to cover the galvanized bottom die of the ceiling, but the surface of the galvanized steel plate is smoother, so that the phenomena of hollowing, cracking and even large-area falling of the ceiling plastering are easily caused in the plastering and surface layer plastering processes of the subsequent ceiling, and the appearance quality and the use function of the project are seriously influenced.
In order to solve the common quality problems, an improved type of steel bar truss floor support plate, namely a steel bar truss floor support plate with a detachable bottom die, appears in the market at present. However, the cost of the improved steel bar truss floor support plate is relatively high, the bottom die is labor-consuming and time-consuming to remove, and the top surface of the floor slab is provided with full-distributed holes even after the bottom die is removed, so that the plastering quality around the holes is not easy to guarantee. That is, the improved steel bar truss floor slab (detachable bottom die) has solved some problems to some extent from the technical point of view, but has not solved the problems completely, and has poor economical efficiency.
And seventhly, the floor form of the fabricated steel structure building can be divided into 'floor on beam and floor embedded with beam' according to the relative position of the beam and the plate. The beam is embedded into the floor, namely the beam and the plate are integrated, so that the ceiling is beneficial to public buildings needing suspended ceilings and general residential buildings without suspended ceilings.
To the steel construction public building that often needs the furred ceiling, the roof beam board is integrative to have avoided the pipeline to wear the roof beam, has reduced a great deal of influences of electromechanical pipeline to the structure. For a general steel structure residential building without a suspended ceiling, under many conditions, when the lower part of the steel beam is not provided with a wall body, the steel beam cannot be hidden in the wall body and can only be exposed indoors. The beam is embedded into the floor slab, so that the biggest defect of exposing the beam under the middle plate of the steel structure house is overcome. At the moment, if a beam-slab integrated form is adopted, the adverse effect of indoor exposed beams on the use function is well avoided. But the floor bottom die and the lower flange surface of the steel beam are not even.
The enclosure wall and the partition wall are:
eighthly, in the fabricated steel structure building, the light wallboard (such as ALC lath and the like) has light weight, high construction speed and good heat preservation effect, and has good economic benefit and social benefit especially for full dry construction.
However, in the current building structure, the lightweight wall panels (such as ALC laths) are used as surrounding wall panels or internal partition walls, and there is a problem that the joints of the wall panels are cracked, which causes the cracking of the whole wall surface, and is called as one of the common quality problems of the fabricated steel structure building. Although it is not a safety issue, it is not acceptable to the public, and it affects to some extent the market application of lightweight wall panels (e.g. ALC slats) and even fabricated steel structural buildings.

Secondly, the outer frame steel beam is reversely constructed based on the building requirements:
the floor slab is supported by adopting the angle iron pieces which are arranged intermittently, the angle iron pieces can be arranged in an upright or inverted manner according to the thickness of the floor slab and the space size of the lower flange of the steel beam, and meanwhile, back angle irons are symmetrically arranged on the back of the web plate so as to strengthen the local torsional strength and rigidity of the web plate at the position.
Thirdly, buckling-restrained ductile wallboard based on light cover plate:
the buckling-restrained ductile wallboard is combined with the hidden steel frame, other light-weight high-strength plates can be used as materials (such as ALC plates, calcium silicate plates, ceramic plates and the like) of the cover plates on the two sides instead of precast concrete cover plates, so that firstly, the manufacturing process of the precast cover plates on the two sides can be simplified (the internal reinforcing bars of the concrete cover plates are complex, the local reinforcing bars at the positions of pull bolts need to be reinforced and the like), secondly, the requirement of the ductile wallboard on the capacity of hoisting equipment can be reduced (the thickness of the two side cover plates is rapidly reduced), thirdly, hoisting construction is facilitated (even a mechanical crane is not needed), and the development direction of the industrial construction of the fabricated building is.
Fourthly, the hidden steel frame beam and the hidden steel frame column are hinged:
with a fully articulated connection, the nodal stiffness of the beam column is no longer required to provide lateral stiffness of the body structure. The division of labor of the steel frame and the anti-buckling ductile wallboard is very clear, the steel frame only bears vertical load and does not participate in resisting horizontal load, and the anti-buckling ductile wallboard only is used for resisting horizontal load and does not bear vertical load. The division combination is beneficial to reducing the steel consumption of the main structural frame and the field welding work (the steel beam and the flange of the bracket are not welded, and only the web plate is bolted).
And fifthly, delay connection of the ductile wallboard and the main structure:
when the ductile wallboard is only connected with the upper frame and the lower frame to construct the lateral force resisting component (not connected with the column, which is beneficial to coordination with the door and window opening), if the assumption that the ductile wallboard is synchronously hoisted with the main structure and is in delayed connection (not bearing vertical load) with the main structure is realized in the construction practice, the connection of the embedded steel plate and the frame beam is worth giving a special construction.
In order to realize the above assumption, the connection between the embedded steel plate and the upper frame beam can be directly welded or bolted through the fishplate, and the connection between the embedded steel plate and the lower frame beam can be realized through the fishplate with a large round hole or a long round hole and the embedded steel plate based on the consideration of vertical deformation of the digestion and absorption main structure, or through a so-called double-splint structure.
In the field construction process, the embedded steel plate of the ductile wallboard is welded or bolted with the upper frame on the ground, then the light cover plate is hung on the two sides of the embedded steel plate on the ground, and after the main structure is vertically deformed, the embedded steel plate and the lower frame beam are locked through the special structure between the embedded steel plate and the lower frame beam.
The structure not only realizes the calculation assumption that the wallboard provided by the technical specification of the steel plate shear wall is not subjected to vertical load, but also enables the ductile wallboard to be synchronously hoisted with the main structure, and greatly facilitates the field installation of the ductile wallboard.
Sixthly, the method comprises the following steps: steel bar truss floor bearing plate based on do not tear down the die block:
aiming at a steel bar truss floor support plate without detaching a bottom die, the current idea of seeking improvement and innovation on the structure and process of 'the bottom die can be detached' is abandoned, and a 'special building material (interface agent)' which can be simultaneously fused with a galvanized steel plate bottom die and plastering gypsum and putty is sought to be introduced. The original conventional ceiling thin plastering system can be upgraded, and the novel special interface agent is coated on the smooth galvanized bottom die, so that the galvanized bottom plate of the ceiling achieves a roughening effect, and subsequent interface layers such as plastering gypsum or flexible putty are firmly and effectively stuck.
Compared with the common interface agent, the introduced EC-1 interface agent is a dilute and lubricating glue solution with ultralow viscosity, the bonding strength to a base surface is greatly higher than that of the common interface agent, the guniting construction can be realized, the material is saved, and the efficiency is improved. The EC-1 interface agent can moisten and permeate into the surface of the base layer by utilizing a micro-corrosion permeation combination mechanism, so that the surface between the base layer and the new plastering mortar is more fused, and the adsorption capacity and the interface bonding force are improved.
The galvanized bottom plate after the interface agent is applied is the same as the roughened concrete surface, so that the subsequent thin plastering system operation is more suitable, the construction quality is controllable, and the engineering quality hidden troubles of hollowing, cracking, falling and the like which are easy to occur when the galvanized bottom plate is directly plastered are eliminated.
Therefore, the thin plastering system formed based on the introduction of the novel interface agent not only saves the process of detaching the bottom die, saves labor and time, improves economic benefits, but also effectively avoids the common quality problems of the ceiling thin plastering system. More importantly, the novel thin plastering system effectively guides the research and development direction of the assembled steel structure floor slab system, so that the steel bar truss floor slab with the detachable bottom die can not become the development direction of the industry any more.
Seventhly, inlay the integrative design of roof beam board of floor based on the girder steel:
on the basis of embedding the conventional beam into the floor slab, the bottom die of the steel bar truss floor support plate is creatively and properly improved, namely, the bottom die and the lower flange of the beam are reasonably and properly bent at the 'lap joint starting position' of the bottom die and the lower flange of the beam, so that the bottom die of the floor slab is flush with the surface of the lower flange of the steel beam, and the subsequent decoration and finishing of the ceiling of the floor slab are further facilitated.
Eighthly, the light wall based on the double anti-cracking function:
aiming at the problem that the wall surface of the assembled light wall board is easy to crack, a novel thin plastering system with a dual anti-cracking function for the assembled light wall board is provided, through the novel thin plastering system, the common quality problems of cracking and hollowing of the assembled light wall surface can be effectively inhibited, so that the light wall body with the dual anti-cracking function is formed, and the cracking problem of the wall board of the assembled steel structure house is not one of pain points which block the application of the steel structure house.
In the splicing process of the assembled light lath (such as an autoclaved aerated concrete ALC lath), the processing of the splicing position is the key of wall cracking resistance. Compared with the conventional splicing structure, the thin plastering system is additionally provided with kraft paper for preventing cracking, and simultaneously improves the simple anti-cracking method that the conventional alkali-resistant glass fiber mesh cloth is only laid at the splicing position. On the basis, the assembled light wallboard is effectively formed into a thin plastering system with double anti-cracking functions through the improvement of materials and processes of systems such as the interface agent, the plastering gypsum and the like, and the thin plastering system enables the assembled light wallboard to have the double anti-cracking functions and can be well suitable for assembled steel structure buildings.
