Referring to fig. 1, a connecting structure 300 in the related art is provided with bracket piers 310 on each floor to support a support 320, the bracket piers 310 occupy excessive building clearance, the bracket piers 310 on the bottom affect the building elevation, and the structural stress is complex and the cost is high due to too many bracket piers 310.

Based on the structure, the application provides a weak connected structure and a connected building, wherein the weak connected structure is provided with the cantilever truss on the vertical face of one floor of at least one building main body, the occupied building clearance is less, the influence on the using function of the building is reduced, the bottom face of the cantilever truss is leveled with the bottom face of the connecting body, and the outer vertical face is more attractive.

The technical scheme of the present utility model will be described below with reference to examples and drawings.

In a first aspect, an embodiment of the present application provides a weak link structure 100, see fig. 2, the weak link structure 100 for connecting at least two building bodies 200, the building bodies 200 having a plurality of floors F1-F3. Illustratively, the building main body 200 may be a tower, the number of floors of the tower may be one or more floors, and the weak link structure 100 is disposed between two building main bodies 200 to connect the two building main bodies 200.

The weak link structure 100 includes a cantilever truss 110, a weak link support 120, and a link 130.

The cantilever truss 110 is configured to be disposed on a facade 210 of one of the floors F1 of at least one building body 200 and to extend outwardly. Illustratively, the cantilever truss 110 is disposed on the facade 210 of one of the floors F1 of one of the building bodies 200. Of course, as other examples, the cantilever truss may also be provided on the elevation of one of the floors F2 or F3 of one of the building bodies.

The weak link support 120 is disposed at the top of the cantilever truss 110, and the cantilever truss 110 provides a sufficiently long supporting surface for the weak link support 120, so that the slippage of the weak link support 120 can meet the displacement requirement under the action of an earthquake, and the link body 130 is ensured not to slip and collide under the action of the earthquake. Illustratively, the weak link support 120 is selected from any one of a sliding support, a hinged support, a friction pendulum support, or a rubber support. The sliding support and the hinged support can bear larger load compared with the current support. The ultimate compressive stress which can be borne by the friction pendulum type support is more than several times that of the rubber support, but the cost of the rubber support is lower.

One side end of the link body 130 is connected to the weak link support 120 such that the cantilever truss 110 provides vertical support to the link body 130. The bottom side end of the connection body 130 is formed with a clearance recess 131, the cantilever truss 110 is accommodated in the clearance recess 131, and the bottom surface of the cantilever truss 110 is leveled with the bottom surface of the connection body 130.

Compared with the mode that bracket piers are arranged on each floor and the bracket piers at the bottom layer position can obviously protrude out of the bottom of the connecting body in the related technical scheme, the weak connected structure 100 provided by the embodiment of the application has the advantages that the cantilever truss 110 is arranged on the vertical face 210 of one floor F1 of at least one building main body 200, so that on one hand, less building clearance is occupied, and the influence on the using function of a building can be reduced; meanwhile, the bottom surface of the cantilever truss is leveled with the bottom surface of the connector, so that the outer vertical surface is tidier and more attractive; on the other hand, the weak connection structure enables the structural stress to be simplified by reducing the number of bracket piers and supports, and meanwhile, the manufacturing cost can be reduced, the engineering quantity is reduced, and the construction efficiency is improved.

In some embodiments, to transfer the laterally inward force of the weak link abutment 120, referring to fig. 2 and 3, the weak link structure 100 further includes a lateral support structure 140, the lateral support structure 140 being disposed on the cantilever truss 110 and extending laterally of the cantilever truss 110.

Further, referring to fig. 2 and 3, the lateral support structure 140 includes a plurality of truss lateral support beams 141 and at least one web 142. Illustratively, the number of truss side support beams 141 is n, and the number of connecting plates 142 is n-1, wherein n is greater than or equal to 2; a connecting plate 142 is arranged between two adjacent truss lateral supporting beams 141, two truss lateral supporting beams 141 are respectively and fixedly connected to two side ends of the connecting plate 142, and the connection mode can be welding, screwing, riveting and the like. Preferably, the connection plate 142 is a steel plate. A plurality of truss side support beams 141 are spaced apart on top of the cantilever truss 110. Adjacent truss side support beams 141 are integrally connected by at least one connecting plate 142. The lateral support structure 140 may increase the lateral stability of the cantilever truss 110 while providing a greater support area for the weak link support 120.

Because the bearing capacity of the truss is in direct proportion to the height of the truss, the height of the bracket buttress at present is only about 1m, and the bracket buttress 310 is required to be arranged on each floor due to insufficient bearing capacity. Preferably, referring to fig. 2, the cantilever truss of the present utility model has a height H1 of 2m to 3m, and exemplary may be 2.5m, 2.8m or 3m, with better bearing capacity.

Further, to avoid excessive space occupation due to excessive height H1 of the cantilever truss, see FIGS. 2 and 3, the cantilever truss 110 includes a truss bottom chord 111, a truss top chord 112, and a truss web 113.

Truss lower chord 111 is secured to building body 200. Truss upper chord 112 is secured to building body 200 and is disposed opposite truss lower chord 111, with weak link support 120 disposed on the upper side of truss upper chord 112. Truss side support beams 141 are spaced apart on truss upper chord 112. Truss web 113 is disposed between truss upper chord 112 and truss lower chord 111.

The cantilever truss 110 consisting of the truss lower chord 111, the truss upper chord 112 and the truss web member 113 is of a hollow structure, and compared with the existing bracket buttress 310, the cantilever truss 110 can be designed to meet the requirement of pedestrians, and the space occupied by the cantilever truss 110 with higher height is converted into the space occupied by the pedestrians, so that the cantilever truss has better bearing capacity and does not occupy too much space due to too high height. Preferably, to meet pedestrian demand, the clearance H2 of the cantilever truss between the bottom of the truss side support beam 141 on the truss upper chord 112 and the top surface of the truss lower chord is greater than or equal to 2.3m.

Further, referring to fig. 2, truss web 113 includes a plurality of diagonal rods 1131 and at least one vertical rod 1132. The diagonal rods 1131 may be two or more, and the vertical rods 1132 may be one or more. Two of the diagonal rods 1131 and the truss bottom chord 111 form a triangular structure 114. Because the weight of the connecting body 130 is mainly concentrated on the weak link support 120, the connecting portion of the truss upper chord 112 and the weak link support 120 is stressed more, and in order to improve the bearing capacity of the truss upper chord 112, the vertex a of the triangular structure 114 is fixedly connected to the lower side of the truss upper chord 112 and is located in the same longitudinal direction as the weak link support 120.

On the other hand, the lack of support at the ends of the truss lower chord 111 and the truss upper chord 112 away from the facade 210 may result in a reduced bearing capacity, and to avoid the above-mentioned problem, referring to fig. 2, two ends of the vertical rod 1132 are fixedly connected to the ends of the truss lower chord 111 away from the facade 210 and the ends of the truss upper chord 112 away from the facade 210, respectively.

Further, in order to prevent the structural members such as the weak link support 120 from falling, referring to fig. 2, a falling prevention ridge 150 is provided on the top of the cantilever truss 110, and the falling prevention ridge 150 is surrounded on the periphery of the weak link support 120. In order to avoid that the anti-falling ridge 150 and the weak link supporter 120 do not collide with each other when the building main body 200 and the link body 130 relatively move in the case of an earthquake, the anti-falling ridge 150 and the weak link supporter 120 are spaced apart from each other to form a first gap G1.

In some embodiments, referring to fig. 2, the weak link structure 100 further includes a first crash pad 160, the first crash pad 160 being disposed at an end of the bottom of the cantilever truss 110 toward the link 130. The first crash pad 160 serves to buffer the force generated when the bottom of the cantilever truss 110 and the link 130 collide with each other in the event of an earthquake. Illustratively, the first crash pad 160 is a crash pad.

Alternatively, referring to fig. 2, a side of the connection body 130 facing the elevation 210 is spaced apart from the elevation 210 to form a second gap G2; the width of the second gap G2 should meet the requirement that the building body 200 and the connection body 130 do not collide with each other when they are relatively moved by an earthquake.

Alternatively, referring to fig. 2, a side of the connection body 130 facing the cantilever truss 110 is spaced apart from the cantilever truss 110 to form a third gap G3; the width of the third gap G3 should satisfy the requirement that the cantilever truss 110 and the link 130 do not collide with each other when the building body 200 and the link 130 are relatively moved by an earthquake.

Alternatively, referring to fig. 2, the connector 130 has multiple levels of connection floors 132, the building bodies 200 each have multiple levels of building floors 240, and the building floors 240 of two building bodies 200 are connected by one of the levels of connection floors 132. Illustratively, the multi-level connection floor 132 is a first level connection floor 132, a second level connection floor 132, and so on, in that order from bottom to top. The multi-story building floor 240 is a first story building floor 240, a second story building floor 240, and so on, in that order from bottom to top. The first building level 240 of two building bodies 200 is connected by a first floor connecting level 132, the second building level 240 of two building bodies 200 is connected by a second floor connecting level 132, and so on.

In more detail, referring to fig. 2, a space avoiding recess 131 is formed at a side end of the first floor connecting floor 132, and the first floor connecting floor 132 and the building floor 240 are butted by the hollow cantilever truss 110.

In a second aspect, referring to fig. 4, an embodiment of the present application provides a one-piece building comprising a plurality of building bodies 200 and the weak link structure 100 according to the first aspect, wherein the two building bodies 200 are connected by the weak link structure 100. For example, the building body 200 may be two or more, and any two adjacent building bodies 200 are connected by one weak link structure 100.

In some embodiments, the weak link structure 100 further includes a second crash pad 220 and/or a third crash pad 230. Optionally, the second crash pad 220 and/or the third crash pad 230 are crash rubber pads.

The second crash pad 220 is disposed on the elevation 210 and is disposed opposite to the top of the connection body 130 on the same horizontal plane; the second crash pad 220 is used to cushion the forces of the top of the connector 130 colliding with the facade 210 during an earthquake.

The third crash pad 230 is disposed on the facade 210 and is disposed opposite to the weak link support 120 on the same horizontal plane; the third crash pad 230 serves to buffer the force generated when the weak link support 120 or the part of the link 130 attached to the weak link support 120 collides with the elevation 210 in the event of an earthquake.
