Abstract

The invention discloses a building connecting bridge. The two ends of the building connecting bridge are respectively connected with rigid bodies, and the building connecting bridge comprises a plurality of steel beams which are in two-way parallel cross connection. By applying the building connecting bridge disclosed by the invention, the building connecting bridge can bear great deformation and simultaneously save building space.

Description

Building connecting bridge

Technical field

The present invention relates to building field, particularly one building connecting bridge.

Background technology

The connection of the connecting bridge between existing building and the connector between other rigid body and agent structure generally has two kinds of modes:

1, strong ties mode: connecting bridge structure has enough rigidity, connects agent structure for overall, coordinates force and deformation, and two ends have just connect or hinged.Connecting bridge except bearing gravity load, the deformation and internal force of main coordination two-end structure.

2, Weak link mode: if connecting bridge structure is more weak, the structure co-operation of connector both sides cannot be coordinated, now Weak link can be made, way often connecting bridge one end and agent structure hinged, the other end makes sliding support, or sliding support is all made in two ends, and bearing has spacing reset capability, separately add damping unit, to shake geological process to reduce wind.

For above strong ties mode, when wind and geological process, agent structure is except generation translation distortion, and also can produce torsional deflection, torsional effect aggravates with the increase of two ends agent structure asymmetry.Even if for symmetrical connected double_towers structure, due to connecting bridge floor plate distortion, two high buildings apart from outside translation in the same way, due to the phase difference of structural vibration and the uncertainty of earthquake, the counter motion of two high buildings may be produced completely, in high building and connecting bridge, produce huge stress and strain.

For above Weak link mode, under geological process, for preventing connecting bridge landing or colliding with high building, larger sliding space need be designed, and adopt the resets such as neoprene bearing and damping unit.

Summary of the invention

The technical problem to be solved in the present invention cannot take into account connecting bridge distortion and connecting bridge takes up room large defect to overcome prior art, provides a kind of and build connecting bridge.

The present invention solves above-mentioned technical problem by following technical proposals:

A kind of building connecting bridge, two ends are respectively connected with a rigid body, and its feature is, described building connecting bridge comprises the girder steel that some two-way level crossings connect.

Preferably, the hole that the two-way level crossing of described girder steel is formed is parallelogram.

Preferably, described girder steel is steel I-beam or box steel beam.

Preferably, the sharp angle of described parallelogram is 45 degree.Can meet most of building requirements like this.

Preferably, the hole that the two-way level crossing of described girder steel is formed is circular.The building of some special vision requirements can be met like this.

Preferably, described girder steel is deformed steel girder.Improved by the edge of a wing of deformed steel girder, can circular opening be realized.

Preferably, interconnection place of described girder steel is welding or bolt connection.

Preferably, the top of described building connecting bridge is connected with some floor plates, for being slidably connected between described floor plate and described girder steel.Such floor plate can slide above girder steel, does not disturb the distortion of girder steel system.

Preferably, described floor plate is checkered steel plate or profiled sheet.

Preferably, between described girder steel and the described rigid body at two ends for be rigidly connected or hinged.

Positive progressive effect of the present invention is: by utilization of the present invention, in turn saves architectural space while making building connecting bridge can bear very large deformation.

Accompanying drawing explanation

Fig. 1 is the girder steel connection diagram of present pre-ferred embodiments.

Fig. 2 is that the girder steel of present pre-ferred embodiments is connected front view with floor plate.

Fig. 3 is that the girder steel of present pre-ferred embodiments is connected left view with floor plate.

Detailed description of the invention

Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the present invention to be described.

As shown in Figure 1-Figure 3, the present embodiment comprises some girder steels 1, and between girder steel 1, two-way level crossing is connected to form girder steel 1 system, and herein, girder steel 1 adopts steel I-beam, is bolted between girder steel.By interconnection, define the hole of some parallelogram between girder steel 1, generally, the acute angle of parallelogram gets 45 degree, can reach better effect.

Owing to adopting above-mentioned connection between girder steel 1, so described building connecting bridge can bear larger distortion, less, acceptable constraint is produced to the distortion of rigid body and motion simultaneously, further provide certain damping force, reduce the effect of vibration of rigid body.

Be connected with some floor plates 2 above girder steel 1, in order to the distortion preventing floor plate 2 from disturbing girder steel 1 system, floor plate 2 adopts the mode of being slidably connected to be connected to above girder steel 1.Here floor plate 2 adopts profiled sheet.

Adopt between girder steel 1 and two ends rigid body and be rigidly connected, when avoiding the building connecting bridge adopting and flexibly connect, need the situation of additional space.

In some cases, in order to design outward appearance needs, it is circular at this moment will designing the hole formed between girder steel 1, and girder steel 1 just can adopt deformed steel girder, after changing, just can realize circular opening to its edge of a wing.

Although the foregoing describe the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present invention and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection scope of the present invention.
