The specific principle of the invention is as follows:
(1) the fixing seat 2 is fixed on a road and a bridge in advance, and can be used as a matched facility of the road and the bridge in a pouring mode when being built; of course, the invention can also adopt the movable connection mode between the fixed seat 2 and the highway and the bridge, for example, the bottom of the fixed seat 2 is provided with the roller, the fixed seat is moved to the corresponding position by rolling, and the fixed seat is fixed by the corresponding rolling fixing device to limit the rotation of the roller.
(2) The movable fire-resistant connecting mechanism 4 is provided with the fire-resistant isolating piece 5 in advance, and is configured beside the fixed seat 2 according to a corresponding proportion, when the movable fire-resistant connecting mechanism 4 is not used, the movable fire-resistant connecting mechanism is folded into a structure shown in fig. 5 through contraction, at the moment, the second rod body 16 is contained in the first rod body 14, the fourth rod body 26 is contained in the first rod body 14, the fourth movable rod body 12 is partially contained in the third movable rod body 10, meanwhile, the inner angle of the second connecting part 60 is attached to the inner angle which is not connected, and at the moment, the first rod body 14, the third rod body 24, the fourth movable rod body 12 and the third movable rod body 10 are all arranged in parallel. And, the two sets of movable fire-resistant connecting mechanisms 4 are mutually attached, and the outsides thereof are wound by the fireproof isolating pieces 5. The movable fire-resistant connecting mechanism 4 has a small installation space, and the operation of vehicles on roads and bridges is not influenced.
(3) When a traffic accident occurs, the movable fire-resistant connecting mechanism 4 provided with the fire-proof partition 5 is selected, and the first movable rod piece 6 is rapidly inserted into the fixed seat 2.
(4) The two sets of first flexible rods 6 are quickly separated to ensure that the length of the fire barrier 5 between them is sufficient to block a fire.
(5) The height of the first movable rod 6 is adjusted by adjusting the second rod 16 to stretch the first movable rod 6 to ensure that the height of the fire barrier 5 is sufficient to block a fire which can be generated, the adjustment principle is that the second rod 16 is gradually pulled out from the inner cavity of the first rod 14, when the second rod is pulled out for a certain distance, a first sliding block 18 is exposed, the exposed first sliding block 18 is popped out under the action of a first spring 22, the first sliding block 18 can prevent the second rod 16 from retracting into the first rod 14, and of course, when the second rod 16 is required to retract into the first rod 14, only the first sliding block 18 needs to be pressed reversely to enable the second sliding block to enter the first groove 20 completely.
(6) For the same reason, the elongation of the second movable bar member 8 can be adjusted.
(7) In the extension process of the second movable rod 8, the third sliding block 33 can be adjusted cooperatively to raise the bottom of the second movable rod 8, which aims to ensure the angles of the third movable rod 10 and the fourth movable rod 12 and ensure that the fireproof isolation parts 5 of the two third movable rods 10 can isolate a fire from a road and a bridge, when the third sliding block 33 is adjusted, the bolt 40 is rotated by sliding the bolt 40, when fixing is needed, because the circumferential freedom degree of the nut 42 is limited, when the bolt 40 rotates, the distance between the screw cap on the bolt 40 and the nut 42 is gradually reduced, so that the third sliding block 33 is clamped between the screw cap and the nut 42.
(8) In the present invention, the third groove 44 and the fourth groove 46 are connected, and the same fire barrier 5 is connected therein, and the fire barrier 5 can be folded by bending therein.
(9) When the first movable bar members 6 or the third movable bar members 10 are opened, the required length of the fireproof barrier 5 therebetween becomes large, and thus it is necessary to ensure a sufficient length of the fireproof barrier 5, and after ensuring a sufficient length of the fireproof barrier 5 between the first movable bar members 6 or the third movable bar members 10, the fireproof barrier 5 is clamped by the first clamping blocks and the second clamping blocks.
(10) A stop 56 is provided on the fire barrier 5 to prevent the end of the fire barrier 5 from sliding completely out of the third groove 44, the fourth groove 46 or the fifth groove 48.
(11) The fire barrier 5 of the present invention may be made of materials of different fire resistance limits to meet the specific fire resistance requirements in use.
The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
