The specific embodiment
To shown in Figure 6, totally enclosed type Hanging Basket of the present utility model comprises load carrier, hangar system, back anchor system 4, walking system, sealing guard system, bottom die platform and drainage system, anti-shock device, internal mold and support 6 as Fig. 1.
Shown in Fig. 1 to 4, load carrier comprises the connection structure 2 of main truss sheet 1 and main truss sheet 1, and connection structure 2 connects into an integral body with the composition purlin sheet of main truss sheet 1.
Hangar system is used for the beam face is lifted on the load carrier with the lower part, top rail 301, preceding suspender belt 302, preceding suspender belt 303 and back strap 304, back strap 305 before comprising, more than each suspender belt lower end all be connected on the bottom die platform and preceding suspender belt 302,303 upper ends be connected in before on the top rail 301, preceding top rail 301 is installed on the main truss sheet 1, and preceding suspender belt 302,303 is connected on the main truss sheet 1 by preceding top rail 301.The upper end of back strap 304,305 is connected in pours into a mould Liang Tishang.
Walking system is slided anchor 709 after comprising sliding beam 706, Hanging Basket aisle beam 701, the above structural dynamic device 702 of beam face, the following structural dynamic device 707 of beam face and the sliding beam traveling that is located at the bottom die platform centre.As shown in Figure 5 and Figure 6, slide that sliding anchor 709 comprises the sliding anchor davit 7092 of traveling, the sliding anchor spike 7093 of sliding anchor framework 7091 and back after the beam traveling.Also be fixed with the sliding anchor tie 7094 in a back on the sliding anchor framework 7091, the other end of pull bar is a free end, and during suspended basket, the sliding anchor in back is rigidly connected on the case beam, and after suspended basket put in place, the sliding anchor in back was by the dilatory playback of pull bar.
The sealing guard system can be divided into three parts: the one, and Hanging Basket bottom surface enclosed construction 8012 and circumferential safeguard structure 8011, two, sliding anchor enclosed construction 802, three after the traveling, Hanging Basket top cover 803, each several part all are made up of support, panel.Bottom die platform comprises preceding lower transverse beam 501, back lower transverse beam 502 and two-layer up and down, and lower floor is a bottom surface enclosed construction 8012, and the upper strata is a Hanging Basket bed die 504.Bottom surface enclosed construction 8012 is connected on preceding lower transverse beam 501 and the back lower transverse beam 502.Sealing guard system and bottom die platform constitute totally enclosed construction space together.The template of Hanging Basket bed die 504 double as concrete constructions, bottom surface enclosed construction 8012 prevent that with the sealing guard system foreign material from dropping out Hanging Basket as the overcoat of operation.
Drainage system comprises the charge for remittance ditch 901 that is located at the bottom die platform outside and is located at collection box 902 on the bottom die platform.Charge for remittance ditch 901 is connected with collection box 902 by steel pipe, is used for water is collected into collection box 902.To being provided with a plurality of gutters 903, gutter 903 can be set as different numbers as required along bridge in collection box 902 bottoms.
Utilize the reinforcing bar 1001 in the bridge beam body to make anti-shock device, in the beam body of bridge agent structure reinforcing bar 1001 is arranged, draw copper conductor 1002 from 1001, be connected in Hanging Basket, whole device plays the effect of the anti-electricity of Hanging Basket.
During the assembly unit Hanging Basket, the first step is the Hanging Basket each several part on spliced girder face on the case beam of having constructed, the above structural dynamic device 702 of Hanging Basket aisle beam 701, Hanging Basket beam face that comprises walking system, main truss sheet 1, bracing 2, hangar system 3, back anchor system 4 and Hanging Basket top cover 803; Hanging Basket each several part below assembly unit Bridge Beam face on ground or the support comprises bottom die platform, circumferential safeguard structure 8011, the following structural dynamic device 707 of beam face and drainage system; Second step was to use whole lifting of Hanging Basket part below lifting instrument such as the jack beam face that assembly unit in the first step is good, and with this part Hanging Basket with water case beam 11 and be connected; The 3rd step was that bottom die platform is connected with hangar system, made main truss sheet 1 bear Hanging Basket weight by hangar system; The 4th step was to remove the following Hanging Basket part of beam face and water being connected of case beam 11, finished the system conversion.The 5th step was assembling reinforcement, and prestressed bundle and pipeline thereof are installed internal mold and support 6; Copper conductor 1,002 one ends are connected with case beam steel 1001, and the other end is connected with Hanging Basket, finishes ground device, and Hanging Basket assembly unit is so far finished.
After finishing, the Hanging Basket assembly unit can build, and the same with common Hanging Basket, whenever to build and finish a sections, Hanging Basket relies on the traveling forward of its walking system, so that build next sections.
Suspended basket of the present utility model can realize like this: the method that described Hanging Basket is walked forward comprises four steps, the first step is to pass case beam preformed hole 1101 the sliding anchor davit 7092 of traveling is tightened against sliding anchor framework 7091, makes the sliding anchor spike 7093 in back embed preformed hole 1101 and be pressed in the beam body.Second step was active section 8032 to be set to adapt to the needs of traveling, transport of materials etc. below Hanging Basket top cover 803 end plates 8031.Make upwards slippages of active section 8032, loosen suspender belt 302,303 before the hangar system simultaneously, back strap 304,305 makes disengagement between the sliding anchor enclosed construction 802 and Hanging Basket top cover 803 after the traveling.This moment, bottom die platform produced downward displacement, thereby the demoulding as shown in Figure 4 falls within on the sliding anchor 709 in back to sliding beam 706 rears.The 3rd step was to remove back strap 304,305, removed back anchor system 4.The 4th step was to start the suspended basket system, and main truss cradle sheet 1, bottom die platform (band sealing guard system) are drawn by power set 702,707, thereby made whole Hanging Basket vertical shift forward.
After suspended basket puts in place, enter casting process.Anchor system 4 behind the Hanging Basket is set earlier, screws out the sliding anchor davit 7092 of traveling, utilize the sliding anchor tie 7094 in back will slide anchor and retract near the lower transverse beam 502 of back, tighten the sliding anchor davit 7092 of traveling at the preformed hole place again.In the traveling process, because the existence of sliding anchor protection 802 after the traveling, the sliding anchor 709 in back is within the Hanging Basket protection system all the time.
As shown in Figure 4, after the Hanging Basket cantilever is finished, be subjected to place or other factors, in the time of can't removing on the spot, can retreat to solution space and remove then.Hanging Basket top load-carrying members remove with can dismounting on the spot on the beam face after bottom die platform is connected.The Hanging Basket substructure can retreat like this: lower transverse beam 501, lower transverse beam 502 both sides, back respectively add a hook 708 before bottom die platform, are equiped with the travelling wheel 7010 that has drive unit on the hook 708.Bottom die platform 708 is hung on the beam face by 4 hooks, after removing load bearing system and hanging of bottom die platform being connected, starts the drive unit of this travelling wheel 7010, realization Hanging Basket substructure retreat traveling continuously.Certainly, the Hanging Basket substructure also can adopt other modes, as the sliding beam of traveling, bottom die platform rely on mutually, slideway each other, gradation retreats.
Above-mentioned each operation has realized that simply and easily the assembly unit of Hanging Basket, Hanging Basket walk forward and anchoring, when construction finishes needs dismounting Hanging Basket, can by Hanging Basket retreat traveling method Hanging Basket is retreated away continuously walk to correct position again row remove, can adapt to the occasion that the construction below requires Hanging Basket not remove up for the railway network etc.
