CN2306258Y - Bottom running type construction basket - Google Patents

Abstract

The utility model relates to a bottom running type construction hanging basket, which is composed of a main beam, a top beam, a bottom beam, a main beam slide way, a bottom platform, a suspender, etc. The bottom platform can ambulate along a platform slide way, so the span of the beam is decreased, which reduces the self weight of the hanging basket. The utility model has little space occupation, and more convenient and accurate installation and locomotion.

Description

Downstriker construction Hanging Basket

The utility model belongs to concrete casting and constructing apparatus field, refers in particular to a kind of concrete semi girder construction Hanging Basket.

Along with the rapid raising of bridge scientific research, design, manufacturing, construction technology, prestressed reinforced concrete bridge free cantilever casting construction technology is widely used.The necessary capital equipment of this process application is the concrete suspended casting suspended basket.Common prestressed reinforced concrete continuous beam cantilever casting and constructing will exceed the width of pour concrete beam with the upper and lower crossbeam span of Hanging Basket, crossbeam generally will adopt truss form can satisfy intensity, rigidity and stability requirement, such structure design, cause whole Hanging Basket deadweight excessive, take a lot of construction spaces, if the beam body of cast is two when becoming a plurality of split box sections and adopting split type cradle construction, can the split Hanging Basket can't be surmounted mutually because of stretching out top board crossbeam obstruction in addition, and influence construction speed.And because the crossbeam and the girder interchangeability of truss-like are very low, after bridge block construction finished, the main member of Hanging Basket can't be reused in another bridge block cast.Present applied Hanging Basket design, because complex structure, assembly unit, location also often influence the duration of continuous pouring than complexity.

The purpose of this utility model is to propose a kind of downstriker Hanging Basket that can overcome above-mentioned shortcoming.This Hanging Basket adopts lightweight structures, reduces the crossbeam span, and member recycling rate of waterused height, and is applied widely, and its unique downstriker walking location is easier to installing and locating, construction is more saved time raise the efficiency.

The purpose of the utility model realizes by following scheme: downstriker construction Hanging Basket, form by girder, top rail, lower transverse beam, girder slideway, end platform, suspender belt etc., it is characterized in that: the guide rail when being provided with two slideways in the concrete beam poured into a mould bottom and doing that platform moves forward at the end, the lower transverse beam place of end platform is provided with pawl type guide wheel, collude on the guide rail of slideway, have the girder slideway at girder, have running gear to promote girder and move forward.

Accompanying drawing and drawing explanation:

Fig. 1 is the utility model structural representation.

Fig. 2 is the right view of Fig. 1.

Fig. 3 is that the platform slideway engages schematic diagram with crossbeam at the bottom of the utility model.

1-concrete beam; 2-girder slideway; The 3-girder; The 4-top rail;

Platform slideway at the bottom of the 5-; The 6-lower transverse beam; The 7-ratchet wheel; Landing beam at the bottom of the 8-;

The 9-soffit formwork; 10-girder front fulcrum; The 11-running gear;

12-girder rear fulcrum; The 13-truss; The 14-outboard template; The 15-suspender belt.

Below in conjunction with accompanying drawing and embodiment the utility model is done detailed explanation:

On the reinforced concrete beam of having poured into a mould 1, be provided with girder slideway 2, girder front fulcrum 10 has movable pulley, girder rear fulcrum 12 to be located on the girder slideway 2, two point supportings girder 3, set up top rail 4 on the girder 3, be connected end landing beam 8, end platform slideway 5 with lower transverse beam 6 by suspender belt 15, soffit formwork 9 all is erected on the lower transverse beam 6, and truss 13 and outboard template 14 are fixed on the end platform.End platform slideway 5 is to be anchored on the concrete beam 1.When the utility model need move forward, running gear 11 promotes front fulcrum 10, girder 3 drives whole hanging basket and moves, because ratchet wheel 7 is to be buckled on the end platform slideway 5, and ratchet wheel 7 is to be fixed on the lower transverse beam 6, so the end platform of hanging basket and outer side form are whole mobile along end platform slideway, whole moving process not only accurately but also quick, light.

In sum, because the utility model adopted the downstriker structure, significantly reduced the deadweight of hanging basket, the Hanging Basket space also reduces greatly, and this has reduced cost concerning construction, improved efficient, and especially two casees beams are used the utility model simultaneously during pour concrete.This structure design, the standardized production of the Hanging Basket that more helps constructing is on-the-spotly installed more conveniently, and equipment, material recycling rate of waterused height are wider, the more practical novel Hanging Baskets of a kind of compliance.

Claims (1)

1. Downstriker construction Hanging Basket, form by girder, top rail, lower transverse beam, girder slideway, end platform, suspender belt etc., it is characterized in that: be installed with the guide rail of two slideways when doing that platform moves forward at the end in the concrete beam poured into a mould bottom, the lower transverse beam place of end platform is provided with pawl type guide wheel, collude on the guide rail of slideway, have the girder slideway at girder, have running gear to promote girder and move forward.
