Abstract
The invention provides a hidden framing hollow glass curtain wall, comprising upright pillar, cross beam and hollow glass block set on the upright pillar and cross beam. The hollow glass block contains inner glass plate and outer glass plate, round which there is structural glue used to connect inner and outer glass plates. There are inserting parts, whose length is far from less than the length of relative glass plate side, in the structural glue respectively. There are assembling slots in inserting parts and locating structure along the thickness direction of hollow glass plate. Connectors inserting into the assembling slots is set on said hidden framing hollow glass curtain wall and said connector is connected with upright pillar and cross beam. The invention changes the method that the glass of hidden framing glass curtain wall is formed to glass parts by structural glue necessarily and maintaining time for structural glue and relative machining procedure for structural glue and assistant frame is canceled so that unit cost is decreased largely. Construction process is quickened while quality danger generated by structural glue and assistant frame is reduced.
Description
Technical field
The present invention relates to hollow glass curtain wall and curtain wall and use hollow glass plate field
Background technology
As an important form of curtain wall, concealed frame glass curtain wall is used in recent years in a large number.The technology that extensively adopts is at present: curtain skeleton is made of column and crossbeam, by structure glue glass is fixed on the attached frame of aluminium, form an assembly, be fixed on the curtain skeleton by attachment screw and pressing plate then, the curtain wall unit price of this structure is higher relatively.Have certain potential safety hazard simultaneously, the glass plate incident of coming off happens occasionally, and is called by the external world by " time bomb "!
In addition, as secondary joist, also be curtain wall cross beam, install for convenient, often adopted the open lower side section bar, use the deckboard shutoff after installing again, deckboard does not participate in stressed, has caused certain waste.The torsional rotation force of open lower side section bar is learned performance obviously not as remaining silent section bar simultaneously, and it is not very serious adopting the monolithic glass problem mostly in the past.But along with the promulgation of energy conservation standard, nearly all new building curtain wall all will adopt hollow glass, and the architect also more and more tends to adopt macroplate.In accordance with regulations, should carry out the antitorque bearing capacity calculation of crossbeam, but because the calculating of opening section bar is too complicated, also not have ready-made formula and the software can reference,, have potential safety hazard so in the curtain wall project under construction, the overwhelming majority is not all calculated!
Summary of the invention
Technical problem to be solved by this invention provides a kind of brand new, latent frame hollow glass curtain wall reasonable in design.For this reason, the present invention is by the following technical solutions: it comprises column and crossbeam, and be installed in hollow glass plate on column and the crossbeam, the hollow glass plate comprises inner layer glass plate and glass outer plate, be provided with the structure glue that connects inner layer glass plate and glass outer plate around between inner layer glass plate and the glass outer plate, be respectively equipped with inserts in the structure glue all around, the length of inserts is much smaller than the length of side of its place glass edges of boards, inserts is provided with mounting groove, inserts also is provided with the location structure on hollow glass plate thickness direction, described no attached frame hollow glass curtain wall is provided with the connector that is inserted in mounting groove, and described connector is connected with column or crossbeam.Owing to adopt technical scheme of the present invention, having changed concealed frame glass curtain wall glass must be by the way of structure glue and attached frame formation glass assembly, in the middle of hollow glass plate building-up process, cut off several sections inserts of embedding, insert connector before the last wall, directly be fixed on the curtain skeleton by bolt.Can be under the situation that does not increase structure glue thickness, guarantee that internal and external layers of glass has enough bonding strengths, and, the curing time of structure glue and attached frame and procedure of processing correspondingly and structure glue can be saved, greatly reduce unit price, accelerated construction speed.Simultaneously, reduced because the hidden danger of quality that fixed structure glue and attached frame adhesive power and the quality problems of structure glue own cause.
On the basis of technique scheme, the present invention also can adopt following further technical scheme: the side of described crossbeam is provided with spring catch, the side of column is provided with the hole that cooperates with spring catch, in the front of column and crossbeam, is provided with the brace that connects column and crossbeam.Like this, crossbeam links to each other with column by the junction plate of spring catch and front end, not only the attended operation of crossbeam and column is convenient, and the anti-twisting property of curtain skeleton is stronger, and, therefore crossbeam can adopt the section bar of remaining silent, than the opening section bar, improved the utilization rate of material, strengthened the antitorque bearing capacity of crossbeam.In addition, the antitorque bearing capacity calculation of the section bar of remaining silent is simple relatively, can carry out strict checking of bearing capacity according to project situation, eliminates the potential safety hazard that the opening section bar causes fully.
Technical problem to be solved by this invention provides a kind of can be applied to conceal frame hollow glass curtain wall and curtain wall rational in infrastructure hollow glass plate.For this reason, the present invention is by the following technical solutions: it comprises inner layer glass plate and glass outer plate, be provided with the structure glue that connects inner layer glass plate and glass outer plate around between inner layer glass plate and the glass outer plate, be respectively equipped with inserts in the structure glue all around, the length of inserts is much smaller than the length of side of its place glass edges of boards, inserts is provided with the hollow glass plate mounting groove that connector cooperates is installed, and inserts also is provided with the location structure on hollow glass plate thickness direction.Owing to adopt above technical scheme, can be under the situation that does not increase structure glue thickness, guarantee that internal and external layers of glass has enough bonding strengths, and, can save the curing time of structure glue and attached frame and procedure of processing correspondingly and structure glue, greatly reduce unit price, accelerated construction speed.Simultaneously, reduced because the hidden danger of quality that fixed structure glue and attached frame adhesive power and the quality problems of structure glue own cause.
