The specific operation in the step (2) is as follows: the fixing piece comprises flat iron, a closed rivet, a fixing support and a plug, the flat iron is fixed on the fixing support through the closed rivet, the flat iron is arranged below the ridge cover plate in a full length mode and located between the first reinforcing rib and the second reinforcing rib, the ridge cover plate is fixed above the flat iron through the closed rivet, the plug is fixed at the contact position of the first reinforcing rib of the ridge and the roof panel, and the plug is arranged in a full length mode and fixed on the roof panel.
The specific operation of the step (3) is as follows: when two adjacent ridge apron overlap joints, two continuous ridge apron are upper and lower distributions in the overlap joint department, and the ridge apron that is located the below pastes twice clay strip, beats at the clay strip department through the rivet that closes between the ridge apron that is located the top and the ridge apron that is located the below and connects.
The interval between two adjacent rows of rivets is 100-150 mm.
Has the positive and beneficial effects that: the roof ridge cover plate fixing device is simple to operate and good in fixing effect, the roof ridge cover plate is bent to form the reinforcing rib, the physical strength of the roof ridge cover plate is increased, and the wind resistance strength of the roof ridge cover plate is enhanced by the inclination of the reinforcing rib; the roof structure is integrated by fixing the ridge cover plate on the supporting roof plate support through the flat iron, the wind resistance and the strength of the ridge are increased on the premise of not damaging the roof plate, the plug prevents roof rainwater from flowing back, the waterproof property of the ridge is improved, and the lap joint part of the ridge cover plate is fixed through the daub and the rivet, so that the ridge is airtight and watertight.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a three-dimensional effect diagram of a complex hall roof according to an embodiment of the present invention;
in the figure, the following steps are carried out: the roof comprises a ridge cover plate 1, flat irons 2, plugs 3, a roof plate 4, closed rivets 5, a fixed support 6, a first reinforcing rib 7, a second reinforcing rib 8 and a third reinforcing rib 9.
Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1, a method for reinforcing a large-span ridge of a metal roof includes the following steps: (1) manufacturing a plurality of ridge cover plates 1, bending the ridge cover plates 1 to form a plurality of reinforcing ribs, wherein the plurality of reinforcing ribs are sequentially distributed from the bottom to the top of the roof plate 4, a first reinforcing rib 7, a second reinforcing rib 8 and a third reinforcing rib 9 are sequentially arranged from the bottom to the top of the roof plate 4, the number of the reinforcing ribs is determined according to the expansion length of the ridge, the inclined plane distance between two adjacent reinforcing ribs is 160-170mm, the bending depth of the reinforcing ribs is determined according to the gradient of the ridge, the first reinforcing rib 7 is contacted with the bottom of the roof plate after being bent, the height difference between two adjacent reinforcing ribs in the vertical direction is 15-20mm, and when the ridge cover plate is bent to form the reinforcing ribs, the reinforcing ribs can be properly inclined, namely the side surfaces of the reinforcing ribs and the surface of the ridge cover plate 1 form an inclined angle, and the wind resistance of the ridge is facilitated; the bending depth of strengthening rib is generally controlled at 10mm ~20mm, and under the general condition, the roofing slope is big more, and the bending depth of strengthening rib is deepened more, and when the slope is less bending depth is shallower, can't satisfy the intensity requirement, the quantity that increases the strengthening rib of bending satisfies the intensity requirement.
(2) Fixing the plurality of ridge cover plates 1 in the step (1) with the roof plate 4 by using a fixing piece, and specifically operating as follows: the fixing piece is flat iron 2, close rivet 5, fixing support 6 and end cap 3, at first use close rivet 5 with flat iron 2 to fix on fixing support 6, flat iron 2 leads to long the below of arranging ridge apron 1 and is located between first stiffening rib 7 and second stiffening rib 8, ridge apron 1 is fixed in flat iron 2 top through close rivet 5, end cap 3 is fixed in the first stiffening rib 7 of ridge and roof boarding 4 contact position, end cap 3 leads to long the arranging and is fixed in on roof boarding 4, flat iron 2 must be fixed in on the fixing support 6 that supports roof boarding 4, form overall structure through close rivet 5 ridge apron 1 and roof boarding 4 etc.. The number of the closed rivets 5 is set according to the size of a ridge, and the flat iron 2, the roof board 4 and the fixed support 6 are fixed through the closed rivets 5. The ridge cover plate 1, the roof plate 4 and the fixed support 6 form an integral structure, and the ridge strength is increased. The first reinforcing rib 7 is in contact with the roof panel 4, so that water return is easy to occur, the plug 3 is used for being fixed on the roof panel 4 in a full-length mode, water flow return is prevented, and the waterproof performance of the ridge is enhanced. The flat iron 2 is also normally arranged, and is generally 40X 3mm flat iron, the flat iron 2 and the ridge cover plate 1 are generally fixed by a closed rivet 5 at a distance of 150mm, the ridge cover plate 1 and the roof plate 4 are fixed by the closed rivet 5 and the flat iron 2, and the ridge cover plate 1 is fixed while the roof plate is not damaged.
(3) Fixing the lap joint of two adjacent ridge cover plates 1 in the step (2): the specific operation is as follows: when two adjacent ridge lid 1 boards overlap joint, two ridge apron 1 that link to each other distribute about the overlap joint department, and ridge apron 1 that is located the below pastes twice clay strip, beats at the clay strip department through close rivet 5 between ridge apron 1 that is located the top and the ridge apron 1 that is located the below and connects. The interval between two adjacent rows of close rivets 5 is 100~150mm, and ridge length differs, confirms 1 process length of ridge apron according to actual length, should use the double daub that leads to long between two ridge apron 1 and beat fixedly in daub place with close rivet 5, generally separates 100mm and beats one row of close rivet 5, leads to long daub and close rivet 5 and connect through pasting double between two ridge apron 1, has guaranteed the intensity and the leak protection ability of ridge apron 1.
