Abstract
The utility model relates to an I-steel-concrete composite beam construction protection platform which strides over the existing road, which comprises a plurality of bearing beams arranged along the bridge direction, a plurality of distribution beams are welded on each bearing beam in the transverse bridge direction, and a platform panel is laid on each distribution beam; every worker steel that corresponds in many spandrel girders sets up two, and every spandrel girder goes up in the same direction as the bridge and welds a couple at the interval, every couple include a montant and one with montant vertically horizontal pole, the montant lower extreme welds with the spandrel girder, upper end and horizontal pole one end fixed connection, horizontal pole other end bottom sets up a pulley, the pulley of the crossbeam bottom of the couple on two spandrel girders that correspond every worker steel supports respectively at worker steel bottom flange board both sides top surface. The utility model discloses simple structure removes in a flexible way, and the underbridge road is normally current when guaranteeing the bridge construction.
Description
Technical Field
The utility model belongs to the technical field of the bridge construction, a worker steel-concrete composite construction's bridge construction is related to, concretely relates to worker steel-concrete composite beam construction protection platform who strides existing road on.
Background
The I-steel-concrete combined beam is a bridge formed by adopting a plurality of large I-steels as a main bearing structure, wherein the I-steels are connected by the cross beams, and the top of the I-steel is provided with the concrete bridge deck. In the construction process, each worker steel is usually firstly erected on two piers of each span, then a support is erected under the bridge, a construction platform is erected on the support, and a constructor installs a connection cross beam between adjacent worker steels on the platform. However, when the existing road is spanned on a construction bridge, the normal passing of the road under the bridge is influenced by erecting the support.
Disclosure of Invention
The utility model aims at the above-mentioned problem, provide an worker's steel-concrete composite beam construction protection platform of striding existing road on, guarantee the underbridge normal current in the work progress.
The technical scheme of the utility model as follows:
the utility model provides an it constructs protection platform to stride worker's steel-concrete composite beam of existing road on, worker's steel-concrete composite beam includes many large-scale worker's steel that set up in the direction of the bridge, connects a crossbeam at every certain interval between adjacent worker's steel, its characterized in that: the construction protection platform is hung below a cross road part of the I-steel-concrete combined beam and comprises a plurality of bearing beams arranged along the bridge direction, a plurality of distribution beams are welded on each bearing beam in the transverse bridge direction, and platform panels are laid on the distribution beams; every worker steel that corresponds in many spandrel girders sets up two, and every spandrel girder goes up in the same direction as the bridge and welds a couple at the interval, every couple include a montant and one with montant vertically horizontal pole, the montant lower extreme welds with the spandrel girder, upper end and horizontal pole one end fixed connection, horizontal pole other end bottom sets up a pulley, the pulley of the crossbeam bottom of the couple on two spandrel girders that correspond every worker steel supports respectively at worker steel bottom flange board both sides top surface.
The utility model discloses simple structure, it is convenient nimble to remove, and protecting effect is good, and the underbridge road is normally current when guaranteeing the bridge construction, is particularly useful for going up the construction of worker steel-concrete composite beam of striding urban road.
Drawings
FIG. 1 is a schematic structural view of the transverse direction of the present invention;
fig. 2 is a schematic diagram of the structure of the present invention viewed from the bridge direction.
Detailed Description
As shown in fig. 1 and 2, the composite beam of the industrial steel and the concrete comprises a plurality of large industrial steels 1 arranged along the bridge direction, a cross beam 2 is connected between adjacent industrial steels at certain intervals, a construction protection platform is suspended below the road-crossing part of the composite beam of the industrial steel and the concrete, the construction protection platform comprises a plurality of bearing beams 3 arranged along the bridge direction, a plurality of distributing beams 4 are welded on each bearing beam along the bridge direction, and a platform panel 5 is paved on each distributing beam; correspond every worker steel in many spandrels and set up two, every spandrel girder 3 goes up to bridge and welds a couple at every uniform distance, every couple include a montant 6 and one with montant vertically horizontal pole 7, the montant lower extreme welds with the spandrel girder, upper end and horizontal pole one end fixed connection, horizontal pole other end bottom sets up a pulley 8, the pulley 8 of the crossbeam bottom of the couple on two spandrel girders that correspond every worker steel supports respectively at 1 lower flange board both sides top surface of worker steel.
The utility model discloses during the concrete implementation, for platform installation and dismantlement, can with construction protection platform is divided into a plurality of sections in the same direction as the bridge, connects gradually through round pin axle 9 between the spandrel girder tip of each section.
The utility model discloses when the construction, a plurality of platform segments of pre-processing, the couple on every segment is preceding not welded, reserves the space of later stage installation couple on the platform panel. After the I-steel of the I-steel-concrete composite beam is hoisted in place, a platform section is hoisted to the position below the I-steel by a crane at the top of the I-steel on one side of the underbridge road 10, constructors weld hooks with bearing beams one by one on a platform and hang the hooks on flange plates below the I-steel, the section slides towards the midspan after one platform section is installed, then the next section is hoisted and installed, and the bearing beams of each subsequent section are sequentially connected with the bearing beam of the previous section through a line shaft. After the whole platform is installed, constructors carry out the I-steel connection construction of the I-steel-concrete combined beam on the platform. After the bridge construction is finished, the platform is hoisted on the bridge by a hoisting machine, and the platform is unloaded section by section on one side of the road.
Claims (2)
