Abstract
The utility model provides a temporary support used for erection of a suspension crossbeam. The temporary support used for erection of the suspension crossbeam comprises at least two steel pipes, wherein the two steel pipes are parallel to each other and are fixed on a support base in a mode that the steel pipes are perpendicular to the ground, an adjusting device is arranged on the top of each steel pipe, a jack supporting platform is arranged between the steel pipes and is located below the adjusting devices, the upper end wall of each adjusting device comprises a section of stretchable wall, a sand leaking hole is formed on the wall, below each stretchable wall, of each adjusting device, each sand leaking hole protrudes outwards, a trapezoid is formed by each sand leaking hole and the lateral wall of a corresponding adjusting device, a cover is arranged on the outer side of each sand leaking hole, each adjusting device is filled with fine sand, and a supporting flat plate is arranged on the surface of the fine sand. The temporary support used for erection of the suspension crossbeam has the advantages that due to the fact that the height of the supporting platform is adjusted smoothly through the matching between the fine sand placed in the adjusting devices and a jack, the controllability of height adjustment of the support is improved, and labor intensity of operators is relieved.
Description
Technical field
The utility model relates to the building operations supporting facility, relates in particular to a kind of falsework that sets up for unsettled crossbeam.
Background technology
Along with The development in society and economy, the road and bridge construction in cities and towns is also perfect rapidly, and therefore, in the building operations of present stage, particularly regular meeting runs into the problem of setting up to unsettled crossbeam during bridge construction.
Present stage need be set up a plurality of interim supports usually when unsettled crossbeam is set up, then crossbeam is set up on the bridge pier on this support and both sides, in erection process, need the horizontal uniformity of crossbeam is adjusted, can adopt a plurality of jack while back timbers or adopt crane to adjust.Because stability is difficult to control, and then the control of precision is wasted time and energy when adopting said method to adjust.
Summary of the invention
The utility model provides a kind of falsework that sets up for unsettled crossbeam, to overcome the deficiencies in the prior art, improves the controllability that support height is adjusted, and reduces labour intensity.
The utility model provides a kind of falsework that sets up for unsettled crossbeam, comprising: at least two steel pipes, and described two steel pipes are parallel to each other and perpendicular to the ground being fixed on the carrier base; The top of described steel pipe is provided with adjusting device, be provided with the jack support platform between the described steel pipe, described jack support platform is positioned at the below of described adjusting device, the upper end wall of described adjusting device comprises one section flexible wall, and the wall of described flexible wall below is provided with leakage sand hole, and described leakage sand hole outwards protrudes, become one trapezoidal with the sidewall of described adjusting device, the hole peripheral hardware of described leakage sand hole has port lid, fills full fine sand in the described adjusting device, and described fine sand is placed with support plate on the surface.
Further, the flexible height of the described flexible wall of above-mentioned falsework is greater than 3 centimetres.
Further, the height of the described adjusting device of above-mentioned falsework is between 20 centimetres to 40 centimetres.
The utility model provides a kind of falsework that sets up for unsettled crossbeam cooperates the height of adjusting support platform stably by fine sand and the jack of filling in the adjusting device, has improved the controllability that support height is adjusted, and has reduced operator's labour intensity.
Description of drawings
Fig. 1 is the overall structure figure of a kind of falsework embodiment one that sets up for unsettled crossbeam of the utility model.
The specific embodiment
Fig. 1 is the overall structure figure of a kind of falsework embodiment one that sets up for unsettled crossbeam of the utility model, as shown in Figure 1, a kind of falsework that sets up for unsettled crossbeam, comprise: at least two steel pipes 1, optionally, in actual applications, can select three or four steel pipes for use according to the stability that supports and supported weight, in the present embodiment, select two steel pipes 1 for use, these two steel pipes are parallel to each other and perpendicular to the ground being fixed on the carrier base 2, the top of steel pipe 1 is provided with adjusting device 3, be provided with jack support platform 4 between two steel pipes 1, this jack support platform 4 is positioned at the below of adjusting device 3, and the mode with welding is fixed on the wall of steel pipe 1, the upper end wall of adjusting device 3 comprises one section flexible wall 31, the wall of flexible wall 31 belows is provided with Lou sand hole 32, this leaks sand hole 32 and outwards protrudes, become one trapezoidal with the sidewall of adjusting device 3, at the hole peripheral hardware that leaks sand hole 32 port lid 33 is arranged, change fine sand component in the adjusting device 3 by open closed port lid 33, leaking the purpose that sand hole is trapezoidal design is to flow in order to slow down fine sand, in order to improve the controllability that support height is adjusted.Simultaneously, fill full fine sand in the adjusting device 3, be placed with support plate 5 on the surface of fine sand.Further, can play the cushioning effect to institute's ballast power in order to guarantee adjusting device 3 interior sands, the flexible height of flexible wall 31 is greater than 3 centimetres, and the height of this adjusting device 3 is generally between 20 centimetres to 40 centimetres.In the present embodiment, the height of adjusting device 3 is 30 centimetres, the flexible of flexible wall 31 highly is chosen for five centimetres, this flexible wall 31 can be chosen folded tube or two and save the movable pipe that is nested, its objective is to stop sand flow to go out, can put sand and move down by the pressure of support plate 5 by leaking sand hole 32 again simultaneously.
It should be noted that at last: above each embodiment is not intended to limit only in order to the technical solution of the utility model to be described; Although have been described in detail with reference to the utility model of aforementioned each embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps some or all of technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of each embodiment technical scheme of the utility model.
