Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Shown in Fig. 1 and Fig. 2, the invention provides a kind of combined bridge isolation frame, it comprises main truss montant 1, outrigger 2, inside bracket 3, wedge shape liner 4 and to drawing device 6.
This main truss montant 1, can select H profile steel usually, and wedge shape liner 4 is arranged in groove 11, and the concrete quantity of wedge shape liner 4 rationally can be determined according to the length of main truss montant 1 and stressing conditions.
This outrigger 2 is fixed on the side of main truss montant 1, and inside bracket 3 and outrigger 2 are oppositely arranged, and are fixed on the opposite side of main truss montant 1, usually can by outrigger 2 and inside bracket 3 to drawing anchor ear on main truss montant 1.
To drawing device 6 for running through the screw rod of outrigger 2 and inside bracket 3, the two ends of screw rod are separately fixed in outrigger 2 and inside bracket 3 by nut.
Shown in Figure 3, wedge shape liner 4 its be made up of the fixation side force bearing plate 41 be oppositely arranged and slip side force bearing plate 42, the end face that fixation side force bearing plate 41 and slip side force bearing plate 42 contact is equipped with lozenges, and slip side force bearing plate 42 can move along described lozenges direction.When force bearing plate 42 slip in slip side puts in place, slip side force bearing plate 42 and fixation side force bearing plate 41 are fitted, and the two ends of wedge shape liner 4 are held in two relative inside walls of groove 11 simultaneously.
In order to improve the friction factor of wedge shape liner 4, increasing friction force, the side of fixation side force bearing plate 41 and slip side force bearing plate 42 relative sliding is respectively equipped with fixation side wedge panel 411 and slip side wedge panel 421.Wherein fixation side wedge panel 411 and slip side wedge panel 421 are steel plate, first carry out aluminium-plated process to fixation side wedge panel 411 and slip side wedge panel 421 before using.The contact surface of fixation side force bearing plate 41 and slip side force bearing plate 42 and groove 11 and need polishing to hold out against between fixation side wedge panel 411 and slip side wedge panel 421, ensures that bonding surface fits tightly, makes structural entity uniform force.
In order to improve stability under loading and increase intensity and the rigidity of wedge shape liner 4, fixation side force bearing plate 41 and slip side force bearing plate 42 are also respectively equipped with fixation side stiffener 412 and slip side stiffener 422.Wherein fixation side stiffener 412 is provided with gap near an inside wall of one end of groove 11 and groove 11, and the other end of fixation side stiffener 412 is positioned at fixation side force bearing plate 41.Slip side stiffener 422 is provided with gap near another inside wall of one end of groove 11 and groove 11, and the other end of slip side stiffener 422 is positioned at slip side force bearing plate 42.In the present invention, fixation side force bearing plate 41 is provided with two fixation side stiffeners 412, slip side force bearing plate 42 is provided with two slip side stiffeners 422, wherein two fixation side stiffeners 412 are vertical with fixation side force bearing plate 41 with the inside wall of groove 11 respectively, and slip side stiffener 422 is vertical with slip side force bearing plate 42 with the inside wall of groove 11 respectively.When main truss montant 1 compressive deformation, due to the gap be provided with in advance, main truss montant 1 can not contact fixation side stiffener 412 and slip side stiffener 422, thus can ensure wedge shape liner 4 by fixation side force bearing plate 41 and slip side force bearing plate 42 stressed, can make stressed evenly.In addition be provided with gap also can ensure can not interfere when installing, more convenient workman installs.
In order to prevent wedge shape liner 4 from getting loose because being given a shock, fixation side wedge panel 411 and slip side wedge panel 421 are equipped with check bolt hole.After force bearing plate 42 slip in slip side puts in place, with check bolt 5, fixation side wedge panel 411 and slip side wedge panel 421 are fixed.Wherein check bolt hole is slotted hole, can ensure that check bolt 5 still can penetrate smoothly under wedge shape liner 4 space length changes slip side force bearing plate 42 sliding condition caused.Check bolt 5 adopts high-strength bolt and joins double nut, packing ring, and bolt is executed and twisted in strict accordance with related specifications requirement, prevents bolt from should shake generation and gets loose.
The installation of the wedge shape liner 4 in the present invention should be carried out before main truss montant 1 is exerted pressure.First fixation side force bearing plate 41 is installed, and is temporarily fixed in groove 11.Carry out the installation of slip side force bearing plate 42 again, slide on the upside of fixation side wedge panel 411 when slip side force bearing plate 42 is installed, touch with hammer after putting in place, ensure the not slippage under deadweight state of wedge shape liner 4.Now slip side wedge panel 421 will fit tightly with fixation side wedge panel 411, and fixation side force bearing plate 41 be held in groove 11 one inside, slip side force bearing plate 42 is held in inside another of groove 11 simultaneously.And then main truss montant 1 is exerted pressure, fixation side wedge panel 411 and slip side wedge panel 421 realize self-locking by frictional force, finally penetrate, fastening check bolt 5, complete wedge shape liner 4 and install.Whole installation and fixation procedure technique very simple.
The wedge shape liner 4 in the present invention is adopted to prevent main truss montant 1 compressive deformation from usually there are following three kinds of situations:
As shown in Figure 3, the length of wedge shape liner 4 and main truss montant 1 liner space and groove 11 measure-alike, wedge shape liner 4 is in standard state, fricton-tight.
As shown in Figure 4, the length of wedge shape liner 4 is greater than the size of groove 11, and now slip side force bearing plate 42 needs upward sliding, and wedge shape liner 4 length is shortened, thus makes the consistent size of wedge shape liner 4 and groove 11.
As shown in Figure 5, the length of wedge shape liner 4 is less than the size of groove 11, and now slip side force bearing plate 42 needs slide downward, makes wedge shape liner 4 length, thus makes the consistent size of wedge shape liner 4 and groove 11.
In sum, owing to being provided with wedge shape liner 4 at combined bridge isolation frame, the problem needing the liner designing multiple different size that main truss montant 1 liner space is inconsistent can well be solved, thus better can go the problem on deformation solving main truss montant 1.
Combined bridge isolation frame in the present invention, owing to which employs the wedge shape liner 4 of adjustable self-locking, thus can according to the size in main truss montant 1 liner space, adjust the length of wedge shape liner 4, expand the scope of application of wedge shape liner 4, well solve the inconsistent problem needing the liner designing multiple different size in current main truss montant 1 liner space, thus better can go the problem on deformation solving main truss montant 1.After exerting pressure to main truss montant 1 in maintenance process, fixation side wedge panel 411 and slip side wedge panel 421 form self-locking by frictional force, without the need to extra latch-up structure, make fixation procedure technique simple.Fixation side wedge panel 411 with slip side wedge panel 421 for steel plate wedge shape is close to combination, through aluminium-plated process on it, increase its friction factor, simultaneously, fixation side wedge panel 411 and slip side wedge panel 421 are also fixed by check bolt 5, what make wedge shape liner 4 can prevent from producing because of vibrations gets loose, thus further improves because liner gets loose the deformation effect caused to main truss montant 1.
The present invention is not limited to above-mentioned embodiment, and for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications are also considered as within protection scope of the present invention.The content be not described in detail in this manual belongs to the known prior art of professional and technical personnel in the field.
