Description

Modular building unit and assemble method thereof

Technical field

The present invention relates to a kind of mainly is employed Modular building unit in prefabricated office, hotel and block of flats and the building with similar general character building.Such Modular building unit is box-like structure, and this structure is made and assembling outside can be at the scene, is transported to the building site then, forms the inner room of building with final assembling.

Background technology

Particularly using the light construction standard package to come construction of buildings in the construction of hotel, apartment and students' dormitory is known to everybody, each building standard assembly is a skeleton steel sheel that is formed by all lightweight structures shaped steel that is welded into box like structure, and the plate such as gypsum plank, veneer or oriented strand board ((orientedstrand board) OSB) is housed.Each building standard assembly is initially made a kind of like this (lined) housing that backplate is arranged, and then in factory it is assembled to desired interior trim standard, is transported to final building site at last to be attached in the building.

GB-A-2334045 has disclosed a kind of method of building this building standard assembly.Form many rectangles or other identical shaped framing component, and they are arranged in are parallel to each other and spaced apart relation, with rib as the final skeleton housing.Then, many stulls that form by being positioned on the housing inboard link together them.Skirting board is fixed in the stull.Add the backplate and the endshield of base plate and ceiling, and standard package is carried out facing, to reach its final interior trim standard.

An inevitable characteristic of the standard package of GB-A-2334045 is to make and to assemble whole standard package in single factory.Prefabricated rectangular frame member is carried out setting-out and formed a box-like skeleton steel work with the initial fabrication step that stull links together them.In case this skeleton is welded into its final box-like shape or housing, transports this housing and just cause bigger cost, and need transport factory with truck or the low loader skeleton shell that each is so independently.Therefore, housing is in identical place installing backplate and assembling, and that the scene that will build final building may be left in this place is quite far away.Then, final building site is arrived in the standard package transportation (generally passing through highway) that is fully assembled, to build hotel or block of flats.This is with quite high potential cost of transportation.

Another characteristic of GB-A-2334045 standard package provides internally, and backplate passes the direct heat path that stull arrives framing component.Therefore, the fire in the building that finally builds up causes before the rib or framing component distortion of its structural upright, and the heat passage of fire is shorter relatively.This is the problem that people pay close attention to very much, because the steel of framing component and stull are the lightweight section frameworks, and is easy to be distorted when thermal overload.Therefore, the maximum height of the building of building according to the standard package of GB-A-2334045 is less relatively number of floor levels, about four or five layers usually.

An object of the present invention is to provide a kind of building unit and a kind of construction method that adopts this standard package, and, compare with the material that uses similar grade in known standard assembly building method, the present invention had not only reduced cost but also had improved the refractoriness of building.By improving the refractoriness of each standard package, the present invention just allows to utilize building standard assembly of the present invention to build more towering room combination.

Summary of the invention

The present invention includes as the application's claim 1 to 11 described a kind of Modular building unit with as the method for the described a kind of production standard building unit of the application's claim 12.

Building standard assembly according to the present invention can utilize described in patent application WO68005 number of awaiting the reply when proposing with the application and claimed positioner stacks with level and vertical arrangement; and as retouch in the patent application that proposes with this case WO68006 number with claimed level and vertically being bound up, to form building 20 or the such height of more floors.If desired, can utilize the outside of the such building of oblique structure member cross binding, the available light-duty cold formed steel sections of these oblique structure members self is made.Such stull is well-known.But, if stull is not level but obliquely locatees that possibility carried out such cross binding with regard to not needing.

The lightweight structures shaped steel that is used as structural upright in Modular building of the present invention unit has outstanding tensile strength, but compressive strength is relatively poor relatively.But, by in more selected structural upright, adopting bar or pipe or cable, can provide additional tensile strength.If use bar or pipe, each bar or pipe are preferably gone up at the overall height (height of a whole floor of the building of Jian Zaoing just) of wall lattice framework and are extended so, and preferably be provided with the device that connects this bar or pipe in its each end, with bar or the pipe of aiming at vertical contiguous floors.This is bound in together at vertical floor in succession with final building effectively.If desired, similarly bar, pipe or cable reinforcement can be from an end of building to the other end or the side to extending through the wall lattice framework laterally or pass crossbeam, in a horizontal plane the adjacent modules of the building built is bound in together.

Particularly in order to build the building that is higher than 20 floors or to be subject to the building of the cross shear effect that side direction wind produced, preferably the pressure resistance column with high compressive property comes the exterior wall of building is strengthened, such pressure resistance column or be included in the wall thickness of prefabricated rectangle frame unit perhaps is fixed on the folded outside of each standard package or standard package.

A preferable form of pressure resistance column is to comprise being filled with concrete, preferably being filled with the pillar of the concrete hollow tubular shaped steel of being furnished with reinforcing bar.Shaped steel can for example be thermoformed into the tubular steel material of rectangle or circular cross-section, perhaps can make with the light-duty cold moudling steel of used steel in the remainder that is similar to the building standard assembly.Each root pressure resistance column can be the height of single Modular building unit, perhaps can be the height of two or more floors in the final building.If last situation, then pressure resistance column can be incorporated in each wall lattice framework.Otherwise they can attach to the outside of the building standard assembly that assembles or the outside of the building that assembles.If desired, pressure resistance column can be a precast concrete column, and can be arrangement of reinforcement, and these pillars are received between two or the many spaced parallel columns, and the wall lattice framework is then built around those pillars.

The present invention also provides a kind of method of making Modular building of the present invention unit, and this method is divided in the mode of cost-effective and made building sites at two and carry out, as described in the application's claim 17.Make and assembling sidewall and end wall lattice framework in first building site, and generally also can make all other cold moudling metalwork in first building site easily, comprise crossbeam and any forming metal spare that other will use in final assembly operation.This means, be useful on the lenient side that the equipment of shaped steel cold moudling structural element can be arranged on first building site.Also have, suitable is, carries out the assembling of wall lattice framework in this first building site, and this action need is high accuracy and require the workman to be skilled in technique very.The assembling of wall lattice framework generally is by each root shaped structures steel member being placed in the assembling fixture, by spot welding, line weldering or plug welding all members being welded together then.Therefore, these first manufactured goods of making the building site are one group of flat substantially wall lattice framework, maybe can there be one group such as crossbeam, to be linear structural element substantially, these all members can be loaded on truck or the cargo train flatly, thereby the member of some Modular buildings unit can be loaded on single truck or the cargo train together.Then, these members are transported to second make the building site from first building site, this second makes building site normally in the locality, and it leaves, and to build the place of its final building from all modules that assembles nearer relatively.In second building site, with crossbeam the wall lattice framework is assembled forming housing, and load onto the backplate luggage of going forward side by side for housing and join.Transporting housing from second building site needs single truck or the low loader building standard assembly that each is independent to be transported to final building site to be built into building really, but by adopt assembling building site strategicly in the locality, whole operation can than the assemble method economy of GB-A-2334045 many, all meticulous and offending work of assembling and assembling is finished in latter's requirement in single manufacturing and assembling building site, transport the unit that assembles from this single manufacturing and assembling building site then.

Preferably, structural upright and crossbeam are the C tee sections.As everyone knows, such cross section comprises a back side, two sides and two fronts.Can by overleaf, comprise that one or more sunken type portion gains in strength among one or more in side and the front, and, if desired, can further gain in strength by all comprising flange curved in front one or two.Can produce bigger intensity by being nested together with two C shape shaped steel, one of them C shape shaped steel is swaged forging (swage), and another is swaged forging not or swaged forging in opposite direction, form a box like structure so that two C shape shaped steel assemble, and form one or more continuous box-like pipeline along final combination shaped steel longitudinal extension.

T-shaped plan view from the protruding wall member that the wall lattice framework is extended, respectively comprise two limb portions, a limb portion is positioned at the C tee section of dependency structure column, another limb portion then extends laterally from this its, as a protruding wall, to accept a relevant crossbeam, this crossbeam is inserted in the protruding wall or is enclosed within on this protruding wall be welded on then on the protruding wall.

But, preferably by have as the patent application WO68007 description of awaiting the reply simultaneously with claimed and as the cold-rolled steel in the application's the described cross section of claim 9 form structural upright, crossbeam also has stull.Some cross sections like this are based on a C tee section shape substantially, substitute traditional flat face but maximally utilise large diameter arc.These cross sections are called as multi sphere section C tee section shape in this article.WO68007 also disclosed be suitable for be connected to together such as the structural member of such multi sphere section C tee section shape such as according to the present invention with the connector in the lattice framework of using.In the typical format framework of structural upright, crossbeam and the stull of only using multi sphere section C tee section shape, the length of crossbeam is short, each crossbeam only strides across the single gap between the adjacent structure column, and is connected to structural upright by T-connecting piece or the K shape connector according to WO68007.Perhaps, stull can be wideer than structural upright, and column passes completely through the oblong slots that stamps out in stull in manufacture process.May need to fix the abutment and make lattice framework with welding is rigidity.

The cold moudling elastic steel strip that skirting board is connected to stull is Z-section preferably, and two angles of its formation are the obtuse angle.A longitudinal edge portions of this Z-section is a flange that is fixed in crossbeam, and preferably fixes along the vertical line of the fixed point in the middle of the adjacent structure column.The skirting board of inner cover is fixed on another longitudinal edge portions of Z-section, and this longitudinal edge portions also forms an edge flange.Being used for the fixed form that skirting board is fixed to elastic strip can be any mounting method easily such as adopting tapping screw.Two obtuse angles of preferable Z-section provide elasticity, this elasticity to be enough to reduce transaudient between skirting board and the housing on the enclosure interior for inner cover is installed to.Because skirting board and structural upright and crossbeam keep together by elastic strip, so skirting board does not contact with structural upright or crossbeam anywhere.Therefore, from the skirting board to the structural upright without any directly transaudient, and, more importantly be, the heat passage of a prolongation is provided between skirting board and structural upright, it at first passes elastic strip and arrives stull, then along stull vertically, just be connected to structural upright at last.The heat passage of this prolongation can be structural upright when catching fire good thermal protection is provided in the Modular building unit.Preferably, the skirting board that is used as the inner cover on the enclosure interior comprises two-layer gypsum plank, with sound insulation and heat insulation better.
