Embodiment Construction

[0013] Below in conjunction with accompanying drawing and embodiment the present invention is further described

[0014] Such as figure 1 , figure 2 As shown, the present invention includes two moving roofs 1, two traction ropes 2, two buffer springs 3, two retaining walls 4, two sets of pulleys 5, two sets of weights 6, a fixed roof 7 and two guide rails 9; and two guide rails 9; one end of one piece of mobile roof 1 has an upper cut and one end of the other mobile roof 1 has a lower cut. The lower ends of one piece of movable roof 1 are rollingly connected with two parallel guide rails respectively through rollers 12, and the two pieces of movable roof are respectively provided with locking pins 10 under the other ends, and the two fixed roofs 1 are respectively provided with retaining walls at the ends away from the movable roof 4. The traction ropes passing through the other ends of the two moving roofs 1 pass through the retaining wall 4 respectively, and are connected...

Abstract

The invention discloses a fireproof roof capable of being opened by fixed pulleys. An upper outcut arranged on one end of a mobile roof and a lower outcut arranged on one end of another mobile roof are superposed and are connected through a connecting device. Two parallel guide rails are arranged on fixed roofs; the lower ends of the two mobile roofs are in rolling connection with the two parallel guide rails through rollers respectively; lock pins are arranged under the respective other ends of the two mobile roofs; retaining walls are arranged on the ends of the two fixed roofs away from the mobile roofs respectively; the other ends of the two mobile roofs pass through the retaining walls through haulage cables respectively and are connected with weight blocks via the pulleys; and buffer springs are arranged on one side of each retaining wall facing the mobile roofs. The fireproof roof consists of the two mobile roofs which are connected through the connecting device. When fire happens, the other end of each mobile roof receives the tensile force of each fixed pulley cable wire respectively; the tensile force of each fixed pulley cable wire is provided by the gravity of a suspended weight object; and the roof is opened under the action of tensile force of the fixed pulley cable wires when the connecting device is disconnected.

Description

technical field [0001] The invention relates to a fireproof roof capable of realizing the fireproof function on a large building. Background technique [0002] The fireproof roof used for building fire prevention belongs to a kind of open and close roof. Opening and closing roof is a structural form in which part or all of the roof can be moved or opened and closed. Its realization is to divide a complete roof structure into several movable and fixed units according to certain rules, so that the movable units It can move according to a certain trajectory to achieve the purpose of roof opening and closing. In our country, although the opening and closing roofs of several gymnasiums have been built, generally speaking, the opening and closing roofs are still in their infancy, and there are no national standards or local design specifications at present. Although there are some similarities between the building fire protection mechanism and the opening and closing roof of the...
