Abstract

The utility model discloses a connecting structure between a vestibule and double tower buildings, a support of the vestibule is composed of two steel trusses and a connection steel beam which are connected with each other, the same ends of the lower chords of the two steel trusses are fixed on the same one tower building, namely, the same ends of the lower chords of the two steel trusses are rigidly connected with the same one tower building, the other ends of the lower chords of the two steel trusses are connected with the other one tower building by a rolling support base; Z-shaped section steel folded plates are connected on two ends of the upper chords of each steel truss, and the two ends of the upper chords of each steel truss are connected with the tower buildings at two ends respectively by the Z-shaped section steel folded plates. The utility model can enable the vestibule to freely displace in the certain range when ensuring the self stability of the vestibule, thereby avoiding the excessive restriction to the vestibule by the structure of double tower buildings, greatly decreasing the inner force of the steel truss components in the vestibule, reducing the steel amounts, so that the applied force mode of the whole structure is reasonable, and the damage of the vestibule caused by large displacements of the double tower buildings can be avoided effectively.

Description

Syndeton between a kind of vestibule and the double tower building

Technical field

The utility model relates to the syndeton between a kind of vestibule and the double tower building, belongs to vestibule link technique field between the high building.

Background technology

In modern architecture, high building structure often occurs with the pattern in double tower building, each architectonical of Double-Tower Structure, simultaneously for the ease of passing through between the double tower building, being everlasting is provided with vestibule and often adopts the steel work pattern with the support that is connected vestibule in double tower building between double tower building structure, and the method that pattern adopts at present that is connected in vestibule support and double tower building is the pattern that is rigidly connected.Adopt this rigidly connected method, though have vestibule and reliable advantage of connecting of double tower building, but, because double tower building structure build is huge, the rigidity of himself is also very big, therefore when adopting this kind to rigidly connect connection, the infinitesimal deflection of double tower building structure brings very big endogenetic process will for the vestibule steel structure support that is attached thereto, what the cross section of each member just must be done in the steel structure support like this is bigger, to guarantee enough resistances, so just certainly will cause the waste of material, in case the while also might damage the steel structure support of vestibule when bigger displacement appears in double tower building structure.Therefore the connected mode between existing vestibule and the double tower building still is not ideal enough.

The utility model content

The purpose of this utility model is: provide a kind of rational in infrastructure, safe and reliable, can reduce the rolled steel dosage of vestibule, can improve the vestibule of vestibule self stability and the syndeton between the double tower building again, thereby overcome the deficiencies in the prior art.

The utility model is to constitute like this: the syndeton between a kind of vestibule of the present utility model and the double tower building comprises high building and be connected with vestibule between two high building, the support of its vestibule by two Pin steel trusss be connected girder steel and interconnect and form, the same end of the lower edge of two Pin steel trusss is fixed on the same high building, and promptly the same end of the lower edge of two Pin steel trusss and same high building adopt and be rigidly connected; The other end of the lower edge of two Pin steel trusss is connected with another high building by roller support; On the position at the two ends of winding up of every Pin steel truss, be connected with Z font steel flap, and the two ends of winding up of every Pin steel truss are all passed through Z font steel flap and are connected with the high building at two ends respectively.

One end of above-mentioned Z font steel flap is connected on the truss vertical support or tie-rod that is connected with winding up of steel truss.

On an end of the above-mentioned Z font steel flap that is connected with high building, be connected with shaped steel, be fixed with the embedded part that can be embedded in the high building on the top of shaped steel.

Owing to adopted technique scheme, the utility model reaches by a kind of new syndeton pattern and has both guaranteed effective the connecting of vestibule with double tower building structure, thereby guarantee the stability of vestibule self, make simultaneously the vestibule within the specific limits can free to deflect again, to avoid of the excessive constraint of double tower building structure to vestibule, so just reduced the internal force of steel truss member in the vestibule greatly, thereby can reduce the size of its member and reduce rolled steel dosage, and make the stressed pattern of total more reasonable; When also having avoided double tower building structure bigger displacement to occur simultaneously effectively to the destruction that steel work caused of vestibule.Therefore, the utility model compared with prior art, the advantage that the rolled steel dosage that the utility model not only has vestibule is few, the vestibule self stability is high, but also have advantages such as the syndeton of vestibule is reasonable, safe and reliable, the life-span is long.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples, but not as to restriction of the present utility model.

Embodiment of the present utility model: shown in Fig. 1-4, when promptly between existing two high buildings 1, connecting vestibule, the support of its vestibule by two Pin steel trusss 2 be connected girder steel 3 and interconnect and form, connect between the lower edge that girder steel 3 flatly is connected two Pin steel trusss 2 and between winding up, the structure of steel truss 2 is a traditional structure, promptly by wind up, lower edge and web member connect to form; The same end of the lower edge of two Pin steel trusss 2 is fixed on the same high building 1 by traditional approach, and the same end and the same high building 1 that are about to the lower edge of two Pin steel trusss 2 are rigidly connected; The other end of the lower edge of two Pin steel trusss 2 is connected with another high building 1 by roller support 4; On the position at the two ends of winding up of every Pin steel truss 2, connect Z font steel flap 5, it is that the thick steel plate of 8～15mm is made that Z font steel flap 5 adopts thickness, each bending angle of its Z font steel flap 5 is generally between 30～45 degree, an end of Z font steel flap 5 can be connected on the truss vertical support or tie-rod 6 that is connected with winding up of steel truss 2; Then Z font steel flap 5 all being passed through at the two ends of winding up of every Pin steel truss 2 is connected with the high building 1 at two ends respectively, convenient and reliable in order to connect, mode by welding on an end of the Z font steel flap 5 that each is connected with high building 1 connects a shaped steel 7, the length of shaped steel 7 can be adjusted according to the distance between steel truss 2 and high building 1 agent structure, then the top of shaped steel 7 is welded on the embedded part 8 that is embedded in high building 1 agent structure.
