Background
In high-rise buildings, in order to meet the requirements of building functions, the two tower buildings are connected by galleries, so that a connected structure is formed. The corridor and the tower buildings at the two sides can be rigidly connected or hinged. When rigid connection is adopted, the corridor becomes a main path for transmitting earthquake action between the tower buildings on the two sides, the stress is concentrated under the earthquake action, the earthquake resistant action of the tower buildings on the two sides can be influenced, the tower buildings and the corridor are often required to be particularly strengthened, and the construction cost is high. When the hinge joint is adopted, in order to meet the relative displacement of the tower buildings at two sides under the action of an earthquake, sliding hinge supports are usually adopted between the corridor and the tower buildings at two sides; the sliding hinged support not only meets the requirement of relative displacement of tower buildings on two sides under an earthquake, but also needs to take anti-falling measures, so the sliding hinged support has a complex structure, can be produced by professional manufacturers, and has high manufacturing and construction costs.

The concrete aspects are as follows:
1. the corridor truss of the utility model can adapt to the arbitrary deformation of the tower buildings at both sides under the earthquake working condition without arranging a sliding support, and can not generate overlarge extra load due to the deformation, thereby reducing the interference to the earthquake action of the tower buildings at both sides to the minimum; this makes the rigidity and the array of the tower on both sides unnecessary, thereby reducing the cost.
2. The utility model discloses being connected of truss and both sides tower can release great earthquake and warp, consequently can not bear great load under the earthquake action, satisfies the target of defences of antidetonation under rare meeting earthquake relatively easily, still can regard as an important fire control passageway after the earthquake.
3. When the settlement of the tower buildings on the two sides is inconsistent, the suspension truss of the utility model can also generate corresponding deformation, so that extra load can not be born due to settlement; meanwhile, the composite material has enough rigidity to resist horizontal load and vertical load, and meets the requirement of normal use.
4. The hinge pins are adopted for connection, so that the on-site hoisting is convenient and quick; and the vertical surface structure of the tower can not be damaged.

Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the embodiments are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1-4, the suspension type truss for the connected structure corridor of the utility model comprises a steel structure corridor truss consisting of an upper plane truss, a lower plane truss, a front vertical surface truss and a rear vertical surface truss; the left end and the right end of a lower chord 1 of the steel structure corridor truss are respectively hinged with the lower end of a suspender 2; respectively installing horizontal support rods in an upper chord structure plane and a lower chord structure plane of the steel structure corridor truss; the horizontal support rods positioned on the left sides of the upper chord structure plane and the lower chord structure plane are single support rods 3, and the right ends of the two single support rods 3 are respectively hinged to the middle parts of steel beams 4 on the left sides of the upper chord structure plane and the lower chord structure plane; the horizontal stay bars on the right side of the upper chord structure plane and the lower chord structure plane are both V-shaped stay bars 5, and the corner ends of the two V-shaped stay bars are respectively hinged to the middle parts of steel beams 6 on the right side of the upper chord structure plane and the lower chord structure plane, as shown in figures 2 and 4.
Further, two horizontal diagonal rods 9.1 and 9.2 are respectively hinged to the middle of the steel beam 4 on the left side of the upper-chord structure plane and the middle of the steel beam 6 on the right side of the lower-chord structure plane, and the other ends of the two horizontal diagonal rods 9.1 and 9.2 are respectively hinged to the upper chord 10/the lower chord 1 on the corresponding side, as shown in fig. 2, so that the load of the horizontal stay rods is transmitted to the upper chord/the lower chord on the corresponding side, and the horizontal freedom of the corridor is limited through the action of the horizontal stay rods, so as to resist the load (such as wind load, earthquake action and the like) in the horizontal direction of the corridor.
The utility model discloses the installation briefly states as follows:
step 1, installing a suspender: hoisting a suspension truss, hinging the upper ends of the suspenders 2 at the left and right ends of the lower chord 1 with the corresponding node plates on the side wall of the left tower 7 and the right tower 8 respectively through pin shafts, wherein the axis of each suspender 2 forms an alpha included angle with the vertical line of the tower at the corresponding side, as shown in figure 1; thereby forming a stress system for resisting vertical load;
Because the included angle α between the suspension rod 2 and the vertical plane changes with the magnitude of the horizontal load, and the pin connection can only bear the force in the rod axis direction, only the vertical load (such as the Z coordinate direction in fig. 5) can be borne at this time, so that when the vertical stress is calculated, the suspension truss can be simplified into a rod 11, and the calculation diagram is shown in fig. 5.
The horizontal stay bar and the upper and lower chord structure planes of the suspension truss form a stress system for resisting horizontal load, and the suspension truss can relatively translate or twist along with the tower buildings at two sides in the upper and lower chord structure planes to generate adaptive deformation, so that the included angle beta can be changed; in calculation, the upper chord plane or the lower chord plane of the suspension truss can be simplified into a straight rod 12, and a calculation diagram is shown in fig. 6.
