Roof object hanging hole structure with detachable hoisting steel beam

Abstract

The invention discloses a roof object hanging hole structure with a detachable hoisting steel beam. The roof object hanging hole structure comprises hanging rings and the detachable hoisting steel beam; webs at the ends of the detachable hoisting steel beam are connected with object hanging hole peripheral frame beams through embedded joints arranged on the inner side faces of the object hanging hole peripheral frame beams; the object hanging hole peripheral frame beams are horizontally-arranged frame bodies, and object hanging hole cover plates are arranged above the object hanging hole peripheral frame beams; the detachable hoisting steel beam is hot-rolled I-shaped steel or hot-rolled H-shaped steel, one or more hanging rings and corresponding transverse stiffened plates are arranged in the length direction, and the webs at the ends are provided with a plurality of bolt holes corresponding to the corresponding embedded joints; each embedded joint comprises a steel bar anchored into the corresponding object hanging hole peripheral frame beam, an embedded steel plate anchored into the inner side face and a connecting plate perpendicularly welded to the surface of the embedded steel plate; and the connecting plates are fixed to the corresponding detachable hoisting steel beam through a plurality of corresponding high-strength bolts. According to the roof object hanging hole structure, the object hanging hole cover plates can be opened in real time, and excellent waterproof performance is achieved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a roof hanging hole structure with detachable hoisting steel beams. Background technique [0002] In construction projects, due to equipment size and functional requirements, it is often necessary to reserve a large range of hanging objects on the roof structure. The hanging holes of some projects are blocked with several prefabricated concrete cover plates, and after being blocked, the upper waterproof layer is constructed together with other areas of the entire roof. [0003] The above method of hanging object holes is prone to hidden dangers of water leakage in actual engineering, because there are easy water seepage gaps between the prefabricated concrete cover slab itself, between the cover slab and the cover slab joint, and between the cover slab and the surrounding retaining sill , the construction quality of the upper waterproof layer is uneven.

AI Technical Summary

Problems solved by technology

Therefore, the equipment layout often avoids the projection range of the roof hanging hole, so that the indoor hanging rings should not be directly installed under the concrete prefabricated cover with low bearing capacity as much as possible, which will cause a certain degree of waste of indoor area
