The specific embodiment
Fig. 1 illustrates a modular bearing structure or superstructure S.In this example, the bearing frame of its structure formation one such as building of warehouse or large supermarket, this framework is large-sized cuboid form.
Structure S comprises and a plurality ofly imbeds the vertical support column 1 of ground P by concrete foundation that all columns are connected to each other by many large span horizontal beams.Specifically, the column 1 shown in the figure is to be made by concrete, but the present invention never is limited in this on the one hand naturally, and it can use metal upright post equally, for example, and i iron column (variant does not give and illustrating).In addition, this illustrates quite height, and for example about 10 meters column is provided for the roof of a building or the bearing structure of higher floor with this.It should be understood, however, that the present invention is equally applicable to the bearing structure relevant with supporting the large tracts of land building floor.
Large span horizontal beam 2 and 10 is made by the stacked timber of gummed, but they are made in a different manner.
Therefore, crossbeam 2 is traditional, and its stacked of single gummed by the square-section constitutes, and the height of square-section is 1 meter to 1.2 meters, and width is about 0.2 meter.The end of beam 2 is installed in (more high-visible in Fig. 2) on the metal support plate 40.These metal fittings 40 are traditional, and they are screwed on the side of corresponding column head end with screw.
On the contrary, the large span horizontal beam 10 that is bearing on the support bar 12 of inclination is box-girder type structures, and they will be described in detail with reference to Fig. 2 to 9 below.
Clearly as seen the large span horizontal beam 10 that is bearing on the support bar 12 of inclination is made of two stacked wing plates 16.1 and 16.2 of gummed arranged side by side as Fig. 6 to 8, and they link together by the separator that forms a central space 19.Specifically, the wing plate arranged side by side 16.1 of interconnect level beam 10 and 16.2 separator are made a high fill plate 17 and low fill plate 18 forms, and their each longitudinal directions along beam extend.High and low fill plate 17 and 18 is preferably made by timber, and they are connected adjacent wing plate 16.1 and 16.2 by gummed.
This shows, two wing plates 16.1 arranged side by side and 16.2 link together by high and low fill plate, and the structure that is this form is the box-girder of formation one timber really, and it can reach 1.40 meters highly usually, and width is 0.45 meter magnitude, and the span of such beam can reach 36 meters.
One passive cable 20 can freely pass the central space 19 that forms by this way, and cable is fixed on the corresponding column 1 at its two ends.Because the length of long-span beams 10 can easily reach 36 meters, so, can consider that passive cable 20 is made is not single, but can make an assembly that comprises several cables, it links together with the connector (not shown) end-to-end in mode traditional in the building trade, make the form of sleeve, especially for the structure of this stay-supported bridge joint (guyed bridge).The effect of this passive cable 20 will be explained in detail below.
The head end of column 1 is configured to be suitable for the end of each passive cable 20 of anchoring, and for example, the diameter that such cable has is about 70 millimeters.Specifically, clearly as seen the passive cable 20 that is contained between two wing plates 16.1 arranged side by side and 16.2 has an enlarged head portion 26 on each end as Fig. 3 and 4, and this head extends beyond the end face of described wing plate.Because column 1 is to be made by concrete in this example, so at one end portion's assembled box 30 is arranged in the head end of column.Therefore, this end assembled box 30 is installed in the top of column, and comprises the metal inner core 35 of an I-shaped cross-section, and it vertically extends together with the hollow space of a pair of open-top.Space 31 is communicated with two sides that formed by slit 32, and described slit 32 can be passed through in the end of cable 20.To the enlarged head portion 26 of each passive cable 20, a carrying wedge (bearing wedge) that has inclined-plane 33 is set carries head, each carries wedge 33 and itself carries the Zhu Bishang near the space that is formed by slit 32 that is resisted against assembled box 30.
Do not illustrate although give in the drawings, nature can provide the variant of the vertical pillars that is made of metal, and wherein, the enlarged head portion 26 of passive cable 20 can be carried out anchoring by the loaded plate that is fixed on the column head end.
As among Fig. 5,6 and 8 as seen, the passive cable 20 that is arranged between two wing plates arranged side by side 16.1 and 16.2 of large span horizontal beam 10 passes from the below of the lateral pin 25 of the described wing plate that interconnects.These pins 25 longitudinally are positioned on the installation curve of being scheduled to, and when cable becomes tensioning cable 20 are formed bearing points.Then, Yu Ding installation curve can be embodied as roughly a circular arc line or the camber line of a catenary.As shown in Figure 8, each such pin is embodied as the form of the bolt that passes two wing plates 16.1 arranged side by side and 16.2, and is engaged on its free end by means of nut and is fixed.
As finding more clearly among Fig. 4, two wing plates arranged side by side 16.1 and 16.2 terminate in respectively on the end face 27.1 and 27.2 of perpendicular, they directly be positioned at corresponding column 1 near.In practice, be provided with a little operating clearance amount of magnitude of several centimetres for example, for the end thrust that acts on the large span horizontal beam, nature, this situation is unfavorable, because this can cause the statically indeterminate problem of beam.Specifically, safe angle section 34.1 and 34.2 usefulness screws are screwed on the vertical pillars 1, and the lateral vertical ground that makes each angle section lean against wing plate arranged side by side 16.1 and 16.2 extends.These angle sections are safety elements that opposing is reversed, that is, they are used for preventing that box-girder from around its passive cable any twist motion taking place.
As mentioned above, box-girder 10 is bearing on the support bar 12 of inclination by end plate 21, and end plate 21 is arranged between wing plate arranged side by side 16.1 and 16.2, and is rigidly fixed on it.Therefore these end plates 21 are arranged between two wing plates arranged side by side 16.1 and 16.2, thereby are bearing on the support bar 12 of inclination, and they are fixed on the described wing plate by through bolt 24.Specifically, end plate 21 or distributing plate are connected in the central space 19 of box-girder fully integratedly.
These end plates 21 are preferably made by steel plate, and contiguous corresponding support bar 12, and they terminate on two bearing surfaces, and one of them is a level, and another is vertical.The end 22 of described end plate 21 is bearing in the situation on the support bar 12 of inclination, can be more high-visible in the view of the magnification ratio of Fig. 9.This view clearly demonstrates two bearing surfaces 22.1 and 22.2 of mutually orthogonal, and face 22.1 is essentially level, and face 22.2 is essentially vertical.This view also illustrates one group of through bolt 24, in this example, has 21 such bolts.The other end 23 of end plate 21 is in the top indentation, so that by passive cable 20.
Can see that end plate 21 extends along the direction of the gradient of the support bar 12 that corresponds essentially to inclination, for example, this gradient is about 20 ° with respect to horizontal direction.
The support bar 12 that Fig. 9 also illustrates inclination has Double Circle projection head 15 on its top, comprise that one transmits the base projections 15.1 of vertical support power and the top boss 15.2 of a transmission Horizontal Branch load.These two projections take place to contact with any of end edge of plate 21 in the hope of avoiding by a darker recess 15.3 and spaced apart.Can see, in this case, near the narrowed width of the support bar 12 of inclination its Double Circle projection head 15, like this, described head can be by between the wing plate arranged side by side 16.1,16.2 that forms box-girder 10.This passes in the central space 19 that enters into box-girder Double Circle projection head 15, and like this, the support region on the support bar 12 of inclination is fully protected.Specifically, can see that the shape of base projections 15.1 forms point with the horizontal plane 22.1 of plate 21 basically and contacts, and the shape of top boss 15.2 is transmitted horizontal supporting power on the zone between vertical plane 22.2 and the described end plate 21.
Each support bar 12 that tilts is preferably made by steel, is rendered as the form of the flat-panel component that extends in a vertical plane.
As finding more clearly among Fig. 5, each support bar 12 that tilts is rendered as a cylindrical leading edge 13 in its bottom, and it is received within the relevant accessory 14 that is fixed on the corresponding column 1.For this purpose, accessory 14 is rendered as a cylindrical reel cage 14.1 with a horizontal axis.This can make support bar 12 hinged around a horizontal axis that is fixed on the vertical support column 1.As an auxiliary situation, accessory 14 presents an external surface 14.1 that tilts, and this face does not contact with the adjacent surface at the place, end of the support bar 12 of inclination, like this, allows described support bar to do within the specific limits to move around its bottom level axis angledly.
Also can consider the support bar 12 that tilts is applied etch-proof material and/or fireproof material, to do best protection.
Fig. 5 also is illustrated in the makeshift device of offering help in the assembling process at its right-hand part.
Can see that temporary support structure 100 is made for a metallic support form.Support 100 comprises that one is fixed on horizontal beam 101 on the column 1 by plate 102, and the direction of the described beam that extends along a vertical plane is subjected to the control of the top assembly 107 of a Y shape.Two vertical links 103 and 104 bottoms freely that have on its support bar 12 that is fixed on exactly determined point 105 and 106 places form an angle of determining of 20 ° for example with this with respect to horizontal direction.Therefore, metallic support 100 is against the support bar 12 of the inclination that has been in place and be placed on the position on the vertical pillars 1.In this case, support is enough to fix support bar 12 by the point 105 and 106 on the support bar that tilts, with the gradient of guaranteeing that it is quite correct.Then, the end of box-girder 10 is in place, so that it is bearing on the Double Circle projection head 15 of support bar 12 of inclination.Therefore, such metallic support 100 makes that the installation of box-girder becomes fast, safety simply and completely.Support is preferably stayed on the position, up to bridge joint till this group metal joist on the box-girder finally fixes.
Therefore, in manufacture process, the metal Connection Element that is installed in box-girder inside is to be made of passive cable 20 and two end plates.Because column bears vertical deformation in a small amount under loading, and because the box-girder in its supporting sagging, so little by little tensioning of passive cable 20 upwards spurs box-girder at this point.The tension force that acts on the passive cable 20 has the effect that promotes described cable by the tensioning to cable, till it touches horizontal support pin 25.Also be the head that is used for admitting support bar 12 by two end plates 21 that steel are made, and the compressive force of transfer function to all fibres that constitutes layer of wood, described layer of wood is formed the stacked structure of gummed.
Also be that the stacked transverse beam 2 of gummed has each module of lateral support bearing structure and successional effect between the assembly is provided.Nature in a variant, replaces using traditional cementing layer stoplog, also can use the box-girder that is similar to beam 10, but this can cause superstructure to become very expensive.
The metal joist 5 of Canam type occupies a space, it changes to the minimum value that its end is located from the maximum value of ridge, like this, provides a gradient for the guiding rainwater flows towards box-girder, as the traditional method in the sector, the decentre ridge formation one of the box-girder gradient slightly own.Then, the head end of each metal joist 5 is fixed on the wing plate of box-girder by means of suitable termination bolt (end bolt).It is the function of employed roofing thickness of strip that spacing between the joist 5 changes.
Therefore, the characteristics of the formation of bearing structure of the present invention are, the notion of design is to utilize the power at the place, end that is fixed on the horizontal beam on the column rather than be arranged on inside, neither be by passive hinge but hinge by all actives, these hinges initiatively are to be compressed to form transmitted load on the beam and the excessive load that applies in horizontal plane, this will be achieved by using metal element.Therefore, not to overcome gravity, and be to use gravity to strengthen energy that this energy expends the pothole distortion that is used for being received in the beam end in the column making usually, continues this process, up to obtaining final balance for horizontal cell.Therefore, the potential energy of gravity is not accessory or the bent beam distortion that is used for making the end, but be used for by all hinged support bar on each end that is arranged in beam, and by integratedly in each box-girder and the passive cable that is fixed on the top of column realize compression.
The economic performance of this structure especially is size in the horizontal plane and the balance between the size in the vertical plane, is appreciated that under any circumstance, in the complete cost of superstructure, ground reaction force is an important parameters all the time.
For each box-girder is in place, the processing when wing plate is set level just of all Kongzuis then, by glue being applied on the top surface of wing plate, is in place fill plate and two end plates.Then, one second wing plate is in place, and after this, synthetic assembly is uprightly placed, so that each pin of location, all pin relevant with the passive cable of carrying and all bolts that are used for fixing end plate.All these bolts are tightened with torque wrench naturally, to avoid the cracking of undesirable timber.
Can see importantly that the element of the key of this structure is well protected: this is applicable to passive cable and the bearing area end plate on supporting head part; and the support bar that also is adapted to inclination; in this, they are coated with anticorrosion and/or fireproof enamelled coating.
In above-mentioned all embodiment, the basal surface of two wing plates arranged side by side of large span horizontal beam or intrados are the plane basically, that is, the cross section of beam is a rectangle.
Yet, in a variant, can consider two intrados that wing plate arranged side by side is curved, to form an arch or " hogback ".
A variant like this is shown in Figure 10 and 11.
The identical label that uses in these figure uses and Fig. 6 and 7.
As seen from the figure, inner arc surface 28 is crooked, and like this, the span beam 10 of carrying presents an arch (c), and this arch is maximum value along beam at the place, centre.Particularly, maximum camber (c) can be considered to be provided by the following relationship formula:
c＝0.013×1/2L
Wherein, L is the length of beam 10.Then this is corresponding to 1.3% camber.In beam length was 36 meters special case, the maximum value of this arch was 0.234 meter.
Such arch can obtain the better control to the power that is caused by moment of flexure, and helps water to flow down from roofing, because the cause of such gradient that forms, its guiding rainwater flows towards the end of long-span beams.
Above-mentioned formula c=0.013 * 1/2L does not consider to rest the length of the long-span beams on its hinged support corresponding to the optimization of lever arm.
The present invention is not restricted to above-mentioned all embodiment, and on the contrary, any variant of the basic feature that uses the above regulation of means regeneration of equal value is contained in the present invention.
