Description
Technical field
The utility model relates to the external wall outer insulation linkage, and the utility model relates in particular to a kind of external wall outer insulation wedge shape plastic-steel bolt of encorbelmenting and is applicable to district in all parts of the country multilayer, high level or energy-conservation external thermal insulation system of three step of superelevation floor.
Background technology
Outer heat insulating work is existing nearly 40 years history in Europe.Using maximum is the thin outer heat preservation system of wiping one's face of polystyrene board (EPS).2000 European technology identification tissue (EOTA) issued " the compound outer heat preservation system Europe technology of wiping one's face is assert guide " EOTAETAG004.Become outer heat preservation system and carry out the foundation that technology is assert.
China's 20th century the mid-80 begins to carry out outer heat insulating work pilot, and what at first be used for engineering also is the thin outer heat preservation system of wiping one's face of EPS plate.Because outer insulation is in the plurality of advantages of aspects such as building energy conservation and indoor environment be comfortable, the Ministry of Construction outer heat preservation technology as giving priority to project.And issued external wall outer insulation engineering rules＜JGJ144-2004 in 2005 〉.Application and innovation that it will further promote heat preservation technology outside China develop towards healthy direction.
At present, the heat insulating work amount enlarges rapidly year by year outside China, according to statistics, reached 2.3 hundred million square meters, only accounted for about 3% of China's overall floorage by China's energy saving building in 2005, still there is 97% building to belong to the high energy consumption building, China's building year about 4.2 hundred million tons of standard coals of consumes energy in 2003 account for the power consumption total amount more than 28.5%, many 3 times of dwelling house average energy loss-rate Europe, comfort temperature must be advocated from now on and use energy-saving heat preserving and insulating material than the low 50C in Europe.The EPS warming plate is a kind of lightweight, efficient and cheap oil product, generally believes after 30 years petroleum resources with exhaustion according to relevant authoritative sources, therefore reasonably uses and effective protection EPS plate, builds fine home and shoulders heavy responsibilities.
Though the outer heat insulating work completion time limit is not long, quality problems are many.Subject matter is that topping cracking and ceramic tile hollowing come off, and also has indivedual engineerings to occur being wiped off by strong wind, and rainwater infiltrates into serious problems such as exterior wall inner surface by the crack.These problems will be caused harmful effect to China outer insulation market at the early-stage as if untimely control, and stay potential safety hazard for outer heat insulating work.
China is vast in territory; the weather conditions difference is very big; the insulation layer of wall face and topping majority be in for a long time high temperature and severe cold, humidity and dry alternately change and sunlight heat radiation, ultraviolet acute irradiation and atmosphere the adverse circumstances of oxidation in; adopting cement mortar or organic polymer mortar all is to belong to poromeric material; there is a large amount of microcracks again in itself; make organic materials such as insulation layer, tack coat and finish coat must occur problem of aging year by year; the long-term use causes bonding failure, can cause the heavy burden of large tracts of land maintenance to the user.
China has a large population and a few land, and the city clay solid brick is disabled in construction, and a large amount of highrise buildings are built fast, and is different with the many conditions of more working with great care in Europe of the external wall outer insulation of building multistory building; And highrise building more adopts shaped steel skeleton veneer brick or aluminium alloy plate.Along with China carried out energy-conservation outer insulation, heat insulation standard of three steps since 2005 in construction work, the thickness each department of dwelling house insulation layer inevitably also will be increased by 40-100mm.In many highrise buildings and superelevation layer, adopt finish materials such as cement sand plaster furring brick, not only can make high buildings and large mansions increase beautiful view; Also increased the protection of second road, thereby be subjected to many architects and Party A's welcome to insulation layer.But, also brought the difficulty of design and construction of heat-insulation system, resolve the ceramic tile difficult problem that comes off and will cause architectural exterior insulation researcher's concern.As everyone knows, in the external wall of high-rise building outer heat preservation system, about grade of cement mortar C5～C10, cement mortar thickness is 25-30mm only, belongs to ultrathin wallboard type, cement mortar is again manually to be put on the soft foam heat-insulation layer of one deck, rigidity is little outside the plane, from the first floor to the top layer overall height from tens meters to more than 100 meters, the centre does not have non-yielding prop contact, vertical applied force stability extreme difference satisfies the basic demand of the compressed member stability of relevant specification regulation far from.Therefore; make topping become the member of qualified transmission deadweight; in the cavity between cement sand plaster layer and the wall body structure enough intensive and powerful supporting member must be set and agent structure couples together; the slenderness ratio of cement sand plaster layer (representing with ratio of height to thickness h/b usually) should be strict controlled in the permissible range of concrete design specification regulation h/b≤25, forms external wall outer insulation supplementary structure system.Otherwise, under gravity load and wind action, only rely on topping self independent weight bearing, because slenderness ratio is excessive, after reduction, (tears open and subtract coefficient
Real protection layer pressurized flexural capacity is very low, vertical bending-buckling very easily takes place destroy.In order to reduce the globality and the continuity of cement mortar float coat crack and enhancing topping, expanded metal lath or welded wire fabric and anti-crack fiber have been laid in the cement sand plaster layer; Do the time spent when considering thermal stresses; generally the area according to floor height and exterior wall also will be provided with longitudinal and transverse cracking resistance partitioning slot in topping; be divided into many row's plates; the parting place becomes the weak link of bearing gravity load; so; as the non-yielding prop connector is not set, just let alone as one " independent stressed member ".Though heat-insulation system does not belong to main body force structure system, its safety and durability definitely can not be ignored.Wherein the gravity load of topping and finish coat is that attached bonding system all can only be passed to agent structure by insulation layer at bonding system or with machinery.Insulation layer is a kind of foamed plastics of very light weight, and very big plasticity is arranged, and intensity is extremely low, does not possess the primary condition of structure stress, is certainly existing hidden danger.
When adopting thin outer heat preservation system (i.e. the simple bonding system of the 05 standard defined) topping of wiping one's face of EPS plate to adopt in the polymer mortar average thickness 5mm, gravity load is very little, generally still can satisfy the power transmission requirement by tack coat.But many engineering practices show that after the cycle, the larger area wall face tends to occur macroscopic continuous crack through the 1-2 cold and heat, and capital construction unit has to carry out the secondary maintenance.High-visible through repairing part rule patch, the highrise building that has for save maintenance cost only keep in repair following which floor, the crack that examines the upper strata still exists in a large number.Like this, many high buildings and large mansions of just building many magnificent magnificences need not just become dark right eclipsed in several years, had destroyed the insulation closed system simultaneously, and the durability of external wall outer insulation and energy conservation are had a greatly reduced quality.Some engineering adopts the way of pasting the back anchor earlier, and crab-bolt is embedding shallow, and the curved ability anti-and vertical displacement of opposing is very low, can only be makeshift, can not fundamentally solve cracking and problem of aging.Belonging to be bonded as Bower Anchor is the outer heat preservation system of assisting admittedly.Because present domestic safety, the long-acting bond-anchorage system of lacking, for this reason, stipulated more strict requirement for external thermal insulation system Tianjin civilian construction energy conservation project construction technology rules " DB29-125-2007 " in 2007.For example, when floor surpassed 7 layers, the gable position should be provided with I shape metal build-in band; Should carry out safety demonstration when highrise building is incubated sticking construction outward more than 20 layers.Increase metal build-in band and will inevitably cause that cold bridge brings many problems such as unfavorable factor of thermal loss to need to solve.
When adopting the outer heat preservation system of EPS plate cement sand plaster (thick wiping one's face) furring brick, gravity load is the former 5～6 times, and the topping load increases, and crack ubiquity and connecting not only makes insulation layer insulation, heat-insulating efficiency reduction; Along with the variation of temperature and strong solar irradiation heat also inevitably cause the furring brick hollowing, come off.For this reason, the decoration of some engineering adopts the elastic coating practice, the crack is ensconced in the rough putty, or adopted dark coating, touches the vision impression of sticking with paste people with this.This way can not tackle the problem at its root equally.The tack coat quality generally lacks effectively under the monitoring means situation at the construction field (site), and in highrise building, the risk that attempt is emitted by its safety of bonding system and the durability of insulation layer power transmission is very big.
At present, some engineering adopts the finer wire flexible connecting member, also exists some to be worth the problem of discussion aspect stress performance.For example; when several highrise buildings adopt in certain city; the furring brick cementing agent has been used the glued raw material of import; execution control and monitoring are also relatively stricter; be completed the ceramic tile dropping situations has just taken place soon; hand over and be less than 1 year; still there is fragmentary face brick dropping situations to take place; to this; caused Party A's great attention,, found that through checking computations this connector is subjected to curved bearing capacity and bending rigidity wretched insufficiency by energy-conservation EPS thickness of slab 50mm of two steps; its middle section flexural strength value has surpassed 2.9 times of design value for strength of material; connector encorbelment the end vertical displacement surpassed 20 times of standard permissible values, lost supporting capacity and rigidity already, illustrate the employing finer wire can not play the non-yielding prop effect; therefore, being directed at topping is cannot stand as " load-carrying members ".This shows that the tile fixing existing family that comes off has just taken place completion of works soon never is accidental, but due to the error of connector force analysis.
According to common construction sequence all is to fit up after the first main body.Topping begins construction relative main body construction in period and lags behind at least and to surpass the time more than 1 year half a year sometimes, and the compressive strain that concrete wall or blockwork deadweight effect produce down is near finishing; Creep deformation is also finished more than 50%.Body of wall and topping compressive deformation life period are poor, so the gravity load that topping transmits must pass on the body of wall by connector.Mechanical analysis shows that connector is a girder construction of encorbelmenting that is fixed on the body of wall, and it is simultaneous being subjected to curved and being cut.The most dangerous stress is encorbelment under gravity load and wind load the acting in conjunction crooked tensile stress of beam root generation rather than the pulling capacity that is produced by wind load merely.Therefore in highrise building; if topping is considered as independent " load-carrying members "; must cause connector to cross situation weak thereby forfeiture supporting capacity and rigidity inefficacy takes place; why the phenomenon that large tracts of land comes off does not appear in furring brick on the above-mentioned engineering protection layer in a short time, mainly is to also have the auxiliary stressed result of tack coat.Because the EPS warming plate is soft, rigidity is very poor, the bonding power transmission of insulation layer will occur relying on for a long time in the future, must cause outside cement mortar protective course sinking, the plane and play drum, produce a large amount of cracks of concentrating; Furring brick hollowing, situation about coming off may take place at any time.Undoubtedly there are bigger hidden danger equally in safety and durability.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, provides a kind of and guarantees that topping has in enough planes and the outer rigidity in plane, makes topping become the stable rigid structural layer in furring brick behind; Simultaneously claimed layer has the ability of enough horizontal Free Transforms, so that discharge the bolt because a kind of external wall outer insulation wedge shape plastic-steel of the thermal stresses that the huge temperature difference causes is encorbelmented.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of external wall outer insulation wedge shape plastic-steel bolt of encorbelmenting, it comprises channel-section steel, the leading portion longitudinal section of described channel-section steel is a wedge shape, the cross section of back segment is an arc, be connected with a spoke shank of bolt by the shank of bolt linkage in described channel-section steel, described spoke shank of bolt links to each other by the end face linkage with the end face of the tapered end of described channel-section steel or the end face of tapered end and arc tips.
The utlity model has very high bending resistance, shear-carrying capacity and bending resistance and draw bearing capacity, safety stock is big.Also have bright calculation diagram and rational Load Transfer route.Have enough powerful rigidity, vertical displacement is little.Topping have in enough planes and the plane outside rigidity and horizontal direction Free Transform ability; make topping become rigid structural layer; guarantee the globality that insulation layer and topping and furring brick finish coat are connected with agent structure, give and prevent because of furring brick hollowing that reasons in structure causes, come off.Improved the heat insulation effect of EPS plate; Be suitable for all kinds of furring brick engineerings, can replace the aluminium alloy plate of expensive price to decorate simultaneously.Connect reliably, fitting operation is easy.Adopt zinc-plated or stainless steel element, non-corroding, the durability of external thermal insulation system can be complementary with agent structure, has alleviated the expense of the long-term maintenance of user greatly, is convenient to simultaneously to supervise, the quality of inspection and Control Engineering.
The target of our intention is to make topping become furring brick stable rigid structural layer behind.The plate that the cracking resistance partitioning slot that the exterior wall external heat insulation protecting layer is divided according to designing institute will be marked is arranged the rigidity bolt of encorbelmenting equably exactly.The material and the cross section type of bolt of reasonably selecting to encorbelment seems extremely important.Data by three kinds of design scheme comparisons of subordinate list 1 every square meter metope show, Tianjin god can reach company and compare with domestic X company: adopt the bolt section area of encorbelmenting only to increase by 11%; But second moment of area increases by 30.7 times, and rigidity improves greatly, be out of shape and reduce; The cross section resistance moment has increased by 7.4 times, and degree of safety increases greatly; Tianjin company and outer insulation National Standard JGJ144-2004 " compare: adopt the bolt section area of encorbelmenting to reduce 66%, surperficial injection moulding must be reduced by the heat transfer loss that cold bridge causes; Second moment of area increases by 3.4 times, and rigidity improves greatly, vertical flexural deformation reduces; The cross section resistance moment has increased by 1.32 times, and degree of safety increases.Generally speaking, adopt the wedge shape plastic-steel bolt heat transfer loss that encorbelments little; Good mechanical performance; The bolt curved plate appearance of encorbelmenting is inserted foam polyphenyl plate EPS or squeezes the plate XPS that contracts all very convenient, adopts the zinc-plated or stainless steel material of full injection moulding, does not have corrosion, and durability and agent structure are complementary, and meet continuable development principle.Become rigid structural layer in order to ensure topping, should not be according to the thickness of the relevant concrete wall of existing Code for design of concrete structures less than 1/25 requirement of story height, the bolt spacing of encorbelmenting in the topping must not surpass 500mm; Should determine to stretch into the solid length of length Ji Anchor in the concrete wall greater than principle according to the frictional resistance of channel-section steel external surface, be taken into wall length 1000mm here with the frictional resistance on round bar surface, cross section.The regulation that meets Tianjin civilian construction energy conservation project construction technology rules " DB29-125-2007 ", according to Tianjin building inspection center (24 station) test, its bending resistance, shear-carrying capacity and rigidity and anchoring ability meet the regulation of relevant specification for structure.Do wedgewise for increasing the anchoring ability imbed channel-section steel in the masonry along its length at channel-section steel simultaneously, and give staying at channel-section steel end cross-sectional plastics shrouding and amplify end; Spoke bolt, plastic base plate and the U-shaped packing ring of the bolt other end of encorbelmenting places the plastic base plate groove or directly is buckled in the curved plate end, and its joint construction not only can make vertical load can directly reach on the croze steel of encorbelmenting; Can form simultaneously the hinged-support of an along continuous straight runs slippage, make each topping plate have enough horizontal distortion abilities, thereby can eliminate in use because of the caused topping cracking of thermal stresses; Prevent the furring brick drum from the structure construction aspect, come off.Adopt 4 to be that example proposes three kinds of connector cross section geometrics and mechanical property relatively sees attached list 1 with every square meter below:
