Set up the protection platform as load -carrying members through the bearing structure attached to on the precast beam body, provide reliable protection to the construction region below, eliminated complicated management that land construction brought and safe risk, the protection platform forming speed of having accelerated simultaneously.
Description
Technical field
The utility model relates to technical field of bridge construction, is specifically related to the protection canopy arrangement of a kind of precast beam install construction.
Background technology
In bridge construction field, engineering superstructure often adopts precast beam structure, after precast beam lifting puts in place, generally needs the construction carrying out seam between Liang Yuliang.When agent structure crosses over the region of the totally-enclosed covered protection of the needs such as existing line or existing building, between precast beam, seam construction needs to transfer in working face to set up protection canopy, plays the protective effect to lower zone.Traditional protection canopy adopts the form of structure of " steel pipe support+steel ceiling ", needs to take construction area for a long time setting up in process, affects greatly, and there is larger potential safety hazard to social environment (as be open to traffic, pedestrian etc.).
Utility model content
For solving the problems of the technologies described above, it is reliable that the utility model provides a kind of protection, sets up the protection canopy arrangement of precast beam install construction easily.
Technical solutions of the utility model are: comprise protection canopy and be arranged in the precast beam between two row's bridge piers, described precast beam comprises the top board being positioned at precast beam top and the web being positioned at precast beam both sides, gap between beam is formed between the described precast beam top board be arranged between two row's bridge piers, described protection canopy is arranged between the relative web of precast beam, be positioned between beam below gap, described protection canopy is fixed on web bottom.
Further, the braced structures that described protection canopy comprises protection face board and evenly arranges along precast beam length direction, described braced structures is fixedly connected with the web plate face of both sides, and described protection face board is arranged in braced structures, and protection face board upper surface is corresponding with gap between beam.
Further, described braced structures comprises left and right braced structures monomer, and described braced structures monomer comprises embedded sleeve barrel, angle steel and standing screw, and described embedded sleeve barrel is arranged in web, and described angle steel side is threaded with embedded sleeve barrel by standing screw.
Further, described braced structures monomer also comprises correcting wedge, described correcting wedge clamping is arranged between angle steel and web, and the lozenges of described correcting wedge is corresponding with web, and described standing screw is threaded with embedded sleeve barrel through angle steel, correcting wedge.
Further, described protection face board comprises the wooden a tree, used in making timber for boats be installed in braced structures and the plank be installed on wooden a tree, used in making timber for boats.
Further, described plank upper surface is equipped with fireprotection layer.
The beneficial effects of the utility model: the utility model sets up protective platform by the braced structures be attached on precast beam body as load-carrying members, to providing reliable protection below construction area, eliminating complex management and security risk that land construction brings simultaneously, accelerating protective platform and form speed.To set up defences on plank upper berth fire bed, can prevent electric welding Mars in work progress from directly dropping on plank and cause fire.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As Figure 1-3, the utility model comprises protection canopy 5 and is arranged in the precast beam 1 between two row's bridge piers, precast beam 1 comprises the top board 2 being positioned at precast beam top and the web 3 being positioned at precast beam both sides, forms gap 4 between beam between the top board 2 being arranged in the precast beam 1 between two row's bridge piers.Protection canopy 5 is arranged between the relative web of precast beam 1, to be positioned between beam below gap 4.
The braced structures that protection canopy 5 comprises protection face board and evenly arranges along precast beam length direction.Braced structures comprises left and right braced structures monomer, and braced structures monomer comprises embedded sleeve barrel 7, angle steel 6, correcting wedge 8 and standing screw 9.Protection face board comprises wooden a tree, used in making timber for boats 10, plank 11 and fireprotection layer 12.Embedded sleeve barrel 7 is arranged in web 3, and angle steel 6 is the steel bar that 90 ° of angles extend along bridge length direction, comprises side and end face, and its side is threaded with embedded sleeve barrel 7 by standing screw 9.Correcting wedge 8 is fixed between the side of angle steel 6 and web 3 plate face by standing screw 9, and its lozenges is corresponding with web 3 plate face, for adjusting the gap between angle steel 6 to web 3 plate face.Wood a tree, used in making timber for boats 10 and plank 11 are fixed on the upper surface of angle steel 6 successively, and fireprotection layer 12 is laid on the upper surface of plank 11.Wherein, fireprotection layer 12 is fire-proof asbestos, causes fire for preventing electric welding Mars in work progress from directly dropping on plank.
The arrangement of this protection canopy arrangement is as follows:
(1) precast beam 1 is when precasting yard is produced, the pre-buried embedded sleeve barrel 7 in relevant position bottom web 3 plate face;
(2) precast beam 1 is in place;
(3) angle steel 6 is arranged on bottom web 3 plate face, correcting wedge 8 is set between angle steel 6 side and web, make the lozenges of correcting wedge 8 corresponding with web 3 plate face, by standing screw 9, angle steel 6 and correcting wedge 8 are fixed on embedded sleeve barrel 7, adjust the gap between angle steel 6 and web 3 by correcting wedge 8, make angle steel fixation;
