Abstract
The utility model relates to a casing refuge bin structure of an existing masonry structure and belongs to the technical field of earthquake-proof strengthening. The casing refuge bin structure comprises a plurality of refuge bin units which are connected abreast and arranged in the south direction and the north direction of the existing masonry structure to form two casing refuge bins in the south direction and the north direction. Each refuge bin unit is of a hexahedron space structure formed by eight steel beams and four steel columns, the six faces are all pulled in pairing mode through steel inclined supports, and steel plates are installed on the upper surface and the lower surface. The steel columns, an outer wall and an inner transverse wall are connected through bolts, and the two casing refuge bins in the south direction and the north direction are mutually pulled through a steel pull rod under a roof. When an earthquake happens, the existing masonry structure and the newly added casing refuge bins resist invasion of earthquake wave together to ensure that the casing refuge bins have large movable space, and people 'hidden' in the casing refuge bins cannot be crushed by broken masonry blocks. The casing refuge bin structure can prolong rescue time of the people.
Description
Technical field
The utility model relates to a kind of existing masonry structure overcoat refuge warehouse structure, belongs to the seismic hardening technical field.
Background technology
The existing building escape method is very many at present, and these methods are mostly based on " escaping ", and these methods perhaps can play some effects to fire, but concerning earthquake, because the uncertainty that earthquake is arrived, the effect that may play is not very big.The old dwelling house of China is in the majority with the masonry brick mix structure, because masonry structure construction cost is lower, China had built a large amount of masonry structures in the past in the mid-90 in last century, because the fragility character of masonry structure material, its shearing resistance, tension and flexural strength are lower, cause the shock resistance of masonry house relatively poor.At home and abroad in all previous violent earthquake, it is quite serious that masonry structure destroys, and can be described as destructive integral body and collapses.Because the uncertainty of earthquake mainly shows factors such as the size and Orientation of seismic wave is uncertain, the earthquake time is uncertain, reaction speed is uncertain, the time that the people " is escaped " does not almost have.Therefore, it is very necessary taking essence, the difficult storehouse measure of effective antidetonation for existing masonry structure without the antidetonation processing.
The utility model content
In order to overcome the problems referred to above, the utility model proposes a kind of existing masonry structure overcoat refuge warehouse structure, it is in conjunction with present old dwelling house overcoat strengthening and rebuilding engineering, the outer race section branch that old dwelling house masonry structure increases newly is set to safe rigid space, the entire building up/down perforation forms safe overcoat refuge warehouse.
The technical solution of the utility model is as follows:
Existing masonry structure overcoat refuge warehouse structure comprises several refuge warehouse unit, and several refuge warehouse unit connect side by side and are arranged at existing masonry structure south, north orientation respectively, thereby constitutes south, two overcoat refuge warehouses of north orientation; Each refuge warehouse unit all adopts the steel diagonal brace to drawing for by 8 section steel beams and 4 hexahedron space structures that steel column constitutes in six faces in described refuge warehouse unit, upper and lower surface, refuge warehouse unit is separately installed with steel plate; Described section steel beam comprises and newly adds vertical girder steel, newly adds horizontal girder steel, and described steel column comprises and newly adds outer steel column, Xin Jianei steel column; Described Xin Jianei steel column is adjacent to outside existing masonry structure exterior wall, and by bolt the interior cross wall between exterior wall, exterior wall and Xin Jianei steel column is linked together, and away from the steel column of existing masonry structure exterior wall one side for newly adding outer steel column; Wherein, the section steel beam parallel with exterior wall is for newly adding vertical girder steel, and the section steel beam vertical with exterior wall be for newly adding horizontal girder steel, newly add vertical girder steel, newly add horizontal girder steel, newly add outer steel column, the Xin Jianei steel column interconnects, and constitutes a hexahedron space structures jointly; South, two overcoat refuge warehouses of north orientation by reinforcing pull rod to drawing connection.
Described reinforcing pull rod is arranged at below, existing masonry structure roof.
Described bolt length is not less than 1000mm, and the bolt longitudinal pitch is 1000mm.
Described refuge warehouse unit adopts door opening diclinic bar steel diagonal brace to socket in the one side that door opening is arranged, and adopts window opening diclinic bar steel diagonal brace to socket in the one side that exterior window is arranged, and all the other adopt no hole right-angled intersection steel diagonal brace to socket on four sides.
The thickness of described steel plate is 20mm.
Described steel column is i iron.
Be welded with floor between described i iron web and the edge of a wing, the i iron coated outside has concrete.
The job practices concrete steps of above-mentioned existing masonry structure overcoat refuge warehouse are as follows:
Step 1: according to design drawing, in existing masonry structure south, the position of both sides, north mount type steel column carries out the steel column basis in advance;
Step 2: assembly type steel column, section steel beam and steel diagonal brace, constitute the refuge warehouse unit, and leave a door unlocked in advance, the window opening mouth, thereby several refuge warehouse unit are arranged side by side and constitute south, two overcoat refuge warehouses of north orientation;
Step 3: Xin Jianei steel column and former masonry structure exterior wall and corresponding interior cross wall are connected by bolt, and the bolt of implanting cross wall in the former masonry structure is connected by nut with the Xin Jianei steel column;
Step 4: the upper and lower surface that steel plate is arranged at the refuge warehouse unit;
Step 5: to drawing, the spacing of reinforcing pull rod is not less than 500mm to the reinforcing pull rod by under-roof with two place's overcoat refuge warehouses of south, north orientation;
Step 6: adopt floor that web and the edge of a wing of steel column i iron are strengthened, then fluid concrete parcel i iron.
Beneficial effect:
Adopt structure of the present utility model, when earthquake is arrived, the invasion and attack that existing masonry structure and newly-increased overcoat refuge warehouse are resisted seismic wave jointly, even former masonry structure produces bigger crack, even local damage, come off, rigidity overcoat refuge warehouse is because the ductility of steel work is good, the part may deform, but overcoat refuge warehouse integrality can be not destroyed, guaranteeing has bigger activity space in the overcoat refuge warehouse, " hiding " people in the overcoat refuge warehouse are unlikely by the masonry fragment kill, delay people's rescue time.Because the overcoat refuge warehouse belongs to combining structure, combining structure has advantages such as save steel, improve the concrete utilization factor, anti-seismic performance is good, cause huge casualties in the time of simultaneously can avoiding macroseism and avoid property loss, this technology has remarkable economic efficiency and social benefit.
