beam rope

9a, 9b are individually fixed in the right and left of bar 5a end.

According to another alternate embodiment, only beam rope is fixed in the end of bar 5a.Identical beam rope is extensible to the structure that comprises several bars.Such structure helps disperseing and absorbing these pressure.This can make this structure that adhesion is preferably arranged.

As described below, beam rope to small part collapses into beam.Two beams are further strengthened by two attachment fasteners that are positioned at the beam two ends at the fixing of connecting rod 5a end.Description with reference to Fig. 3 will be more clear.

Fig. 3 is the vertical view of device among Fig. 2.Each

beam

3a, 3b have two flank parts, are expressed as 3aG, 3aD, 3bG and 3bD in Fig. 3 respectively.Two flanks part is by retaining element 20a, 20b, and as bolt, assembling and being connected.As shown in Figure 2, these retaining elements pass distributing plate 19a, 19b.And these distributing plates are because by

beam rope

9a, 9b covers and can not show in Fig. 3.By retaining element 17G, 17D clamps in the port for flank part 3aG, 3aD, 3bG, 3bD, and is crooked with the flank part that prevents beam.Retaining element 16 locks clamped beam 3a, the retaining element 17 of 3b in addition.Passage 15a, 15b are formed between two flank section divide, and make

beam rope

9a, and 9b is present in the passage.The section of Half Beam so design so that finish the assembling of two Half Beams after, passage 15a, 15b form groove and make

beam rope

9a, 9b is arranged at wherein.Like that,

beam rope

9a, 9b can collapse into beam may protect beam, as in fire to small part.Among Fig. 3, two

beam rope

9a, 9b is fixed in the port of bar 5a.

Fig. 4 is the partial elevation view of beam rope that is fixed in the afterbody of the end of bar and a beam.Shown beam rope 9b among the figure, the end of bar 5a, the tensioner 23b of beam 3b and beam rope 9b.23b is used for regulating the tension force of beam rope 9b, as at mounting rail 3b to bar and after tie-beam rope and the beam.

Fig. 5 is the cross section of beam, is positioned at the middle part of beam.This figure show beam 3 by about two flanks (or Half Beam) 3G, 3D forms, 3G, 3D is connected by fastening devices 20.This figure has also shown that bar 5 and connecting rod 13 are connected on the bar 5 by pivot connector 14, and on the position of the distributing plate 19 of beam tie-beam 3.Fastening devices 20 is passed distributing plate 19.The 3G in left side and the 3D on right side form passage 15, make beam rope (not shown) be bonded on wherein.

Be noted that material seldom in the beam rope passage 15 meaning beams.In addition, its allows beam hitch to be combined in the beam to support it, and passage 15 reduces materials makes beam 3 alleviate.Thus, beam 3 avoids because of the self gravitation bending.And the beam rope places passage 15 to save taking up room of beam rope, and has protected the beam rope, as in fire.If necessary, can insert fire-retardant film closed channel 15, when fire, further protect the beam rope like this.

In a specific embodiment, form passage 15 in the following manner: the beam rope is at the center of gravity point position of beam brace summer.The centre distributor plate 41 of beam places on the beam rope 9.Retaining element 40 passes central plate 41 and connects two flank part 3G, 3D by central plate 41.

In addition, the beam rope passage 15 that flank part 3G, 3D constitute allows relative slip between beams and the beam rope.Such characteristic makes beam 3 freely to adjust by relative beam rope 9.Back characteristic in this accessory system will be particularly advantageous when beam 3 suffers a kind of asymmetrically placed load.For example, air-conditioning or heater are fixedly supported to apart from the beam Centrodistal a bit.Beam 3 has reduced the potential energy that pressure brings with respect to the extra degree of freedom that relative slip provided of beam rope 9.Such just characteristic is further firm this accessory system.

Need in addition to cause concern whether in current system, beam 3 is supported by beam rope 9, and the latter also can various possible variations be connected in the beam rope.

According to a kind of distortion, the beam rope can come brace summer by means of ring or suitable linkage, and allows beam 3 to slide along the beam rope.

According to another distortion, Liang Suoke simply is fixed on the beam, as the upper surface in the beam center.This distortion makes simplification accessory system 1 and production become possibility.Thus, obtained accessory system 1, wherein, the beam rope has remedied beam 3 for pressure to the small part of bar and is applied to moment on the bar, and has produced and act on beam 3 vertical upwarding pressure.The huge simplification that such accessory system has benefited from assembling makes the span of increase beam and the pressure that counteracting is applied on the bar become possibility.The true of beam rope tie-beam 3 makes that further beam-bar of stablizing accessory system is assembled into possibility.

According to another distortion, this beam rope can be made the beam-Suo part of two separation.One of them connects a bar and beam, another part tie-beam and another bar.A kind of beam rope-bar-girder construction of anchor formula obtains thus, and wherein each in two beams-Suo part to small part remedies the moment that beam applies on each bar.

And as previously mentioned, the free additional range that is provided by the relative slip of beam 3 relative beam ropes 9 makes to reduce the potential energy of getting in touch with load pressure and further stablize accessory system and becomes possibility.Yet the slip of the relative beam rope of restraint beam may be avoided the unstability of described accessory system.Finally, sleeve pipe 43 is fixed on the beam rope 9 slip with the relative beam rope of restraint beam.Fig. 6 has provided more detailed explanation.

Fig. 6 is a kind of partial section of a kind of longitudinal center part position along beam.The core that the figure shows beam 3 comprises two flank parts.This cross section is done between these two flank section are divided.Described beam rope 9 is placed in the beam rope passage that forms in the flank beam part, allows beam 3 along with beam rope 9 slides relatively.In one embodiment, illustrated by Fig. 6, beam 3 is set to relative slip in a kind of sliding area of regulation with beam rope 9, and this sliding area is limited by two sleeve pipes 43,45 that are fixed on the beam rope 9.Described two flanks partly connect by centre distributor plate 41, and this plate 41 is fixed to two flank parts by a plurality of borings on it.Like this, described centre distributor plate can be slided along beam rope 9 between sleeve pipe.Difference between the sliding area of regulation and the length of distributing plate defines sliding scale, as shown in Figure 6.

According to a kind of embodiment of variation, distributing plate 19,41 self is further divided into two plates.In these two plates each can both be pre-assembled on flank part 3G, the 3D.Thus, the assembly mode of beam 3 only needs directly to assemble by the fixation side alar part now, for example gets final product with screw.On the other hand, the pre-assembled pattern is exactly a kind of factory mode (factory phase), and it can be controlled easily.Thus, got rid of any mistake in the beam assembling process.The site assembly of beam 3 has been simplified by said method in fact.

Described sliding scale especially be included in beam span 0.2/10,000th and 5/10 is between the 000th.The selection of this scope is lower than the unstable limiting value of described accessory system just,, exceeds the stability of limit entail dangers to system of the sliding scale of beam that is.So characteristic makes beam 3 further pivotally connected with connecting rod, and can adjust according to beam rope 9 in the sliding area that limits.Thus, when beam 3 is subjected to uneven load,, provide additional free scope of activities, may reduce the potential energy relevant like this with load pressure by the slip of beam 3 with respect to the beam rope.As mentioned above, this characteristic makes that stablizing accessory system becomes possibility.Yet, within the sliding area (limiting) that limits, slide by sleeve pipe, be outside the unstable limiting value of accessory system, to slide for fear of beam.

Fig. 7 is a kind of elevation, and its expression attempts to be assemblied in a kind of beam in the accessory system.This beam 3 is further divided into three vertical intercepts 31,32,33.The 3rd section 33 is similar to first section 31, just on direction with respect to the central cross intercept symmetry of beam 3.At least a end of each intercept is stepped, as shown in the figure, is easy to the intercept assembling like this.Better, center intercept 32 has a kind of stepped cross-section, so that can assemble with other two intercepts 31,33.Fixed head 34 is consolidated beam 3 in its stepped cross-section position.These situations of beam of 31,32,33 to integral materials of intercept of making separation are many flexibly, and it makes that accessory system is transported to the logistic work in somewhere is quite easy.And the use of intercept makes needn't take special transportation resources to become possibility, has also reduced the producing cost of assembling beam thus.

If desired, can also adopt much more necessary intercept and be unlikely to take special transportation resources.According to the present invention, length range make is produced in the design of a kind of accessory system like this becomes possibility in the imagination of 5 to 120m beam.In fact, according to the present invention, produce the length that the is arranged in a kind of accessory system beam greater than 120m, and make the overall dimensions of its suitable beam and bar by adjusting, this is feasible in theory.According to the present invention, in the size of the specially designed beam that is applied to described accessory system, can adopt following length: 18,24,30,35,40,55 and 70m.

The material that is used for beam is the veneer material.As a kind of distortion, can use a kind of regeneration steel part of welding.

Especially, described beam rope is made by the derivative of steel or steel, and it has 190,000 and 230, the coefficient of elasticity between the 000MPa.

Yet, the invention is not restricted on the different embodiment of above-mentioned explanation, but the distortion that can have many other those of ordinary skills to be easy to expect.For example, it is contemplated that the vertical intercept that a kind of beam is divided into some odd number amounts.The odd number number of intercept makes and to comprise one and lean against (rest on) and become possibility at the beam of the central cross intercept of Liang Suoshang with respect to its central cross intercept symmetry.To such an extent as to can optimizing, the quantity of intercept reduces the required complete cost of fitting attachments system.
