Abstract
The invention relates to the technical field of bridge construction, in particular to a layout structure and method of protective sheds for precast beam installation and construction. The layout structure comprises the protective sheds and precast beams arranged between two rows of piers. Each precast beam comprises a top plate and webs located on the two sides of the precast beam, wherein the top plate is located on the top of the precast beam. Inter-beam gaps are formed between the top plates of the precast beams located between the two rows of piers. The protective sheds are located between the opposite webs of the adjacent precast beams and located below the Inter-beam gaps. The protective sheds are fixed to the lower portions of the webs. A supporting structure attached to the precast beams is used as a bearing structure for erection of a protective platform, and reliable protection is provided for the lower side of a construction area; besides, complicated management and safety risk caused by land construction is eliminated, and the forming speed of the protective platform is increased.

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 protection canopy method for arranging of a kind of precast beam install construction of the present invention, its technical scheme is: precast beam produce time in web pre-buried embedded sleeve barrel, after precast beam install puts in place, protection canopy both sides are threaded with embedded sleeve barrel by standing screw, to be fixed on by protection canopy between beam below gap.
Further, the protection face board of described protection canopy is supported by the angle steel of both sides, after described precast beam install puts in place, by standing screw, angle steel is arranged on web plate basifacial, and correcting wedge is encased inside between angle steel and web, make the lozenges of correcting wedge corresponding with web plate face, by the gap between correcting wedge adjustment angle steel and web.
Further, after angle steel is in place, angle steel is installed wooden a tree, used in making timber for boats, then on wooden a tree, used in making timber for boats timber boarding.
Further, described plank lays fireprotection layer fire prevention in upper surface after being in place.
Beneficial effect of the present invention: the present invention 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 present invention is described in further detail:
As Figure 1-3, the present invention includes protection canopy 5 and be 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.
