Abstract

The invention belongs to a waterproof joint of a thin metal plate curtain wall, which is used for fixing the curtain wall of a building. The waterproof joint consists of a curtain wall main keel connected with a main structure of the building, and a curtain wall auxiliary keel connected with an outer curtain wall panel, wherein the curtain wall auxiliary keel is arranged on the curtain wall main keel. The waterproof joint is characterized in that: a closed waterproof plate parallel to the outer curtain wall panel is sandwiched between the curtain wall main keel and the curtain wall auxiliary keel; the waterproof plate, the curtain wall main keel and the curtain wall auxiliary keel are fixed through bolted connection; the outer end of the bolted curtain wall auxiliary keel is sealed by a sealant; the size of the waterproof plate is equal to that of an outer curtain wall waterproof area; and the bottom of the waterproof plate is connected with an outdoor apron. In order to solve the technical problem, the invention provides a connection structure in which a waterproof layer is arranged on the inner side of the curtain wall; gaps among plates of the curtain wall are not filled by the sealant and waterproof sealing; and an effective waterproof function is realized in a mode of internal drainage of the facade of the curtain wall.

Description

A kind of thin metal plate curtain wall waterproofing node
Technical field
The invention belongs to the joint construction of a kind of building curtain wall of fixed buildings, be specially adapted to thin metal plate curtain wall connected node.
Background technology
At present, the connection way of metal plate curtain wall is fairly simple, and the appearance of thin metal plate curtain wall has improved the appearance effect of metal plate curtain wall, but adopts the form of cracking between the thin metal plate curtain wall plate slit, and its waterproofing work is had relatively high expectations.At present, the waterproof measure that uses of metal plate curtain wall is to clog with fluid sealant to prevent that outdoor water from infiltrating curtain wall inside between curtain wall plate slit.But, the shortcoming of this measure be to rely on fully fluid sealant functional performance and service life waterproof.Only rely on the quality of fluid sealant and decided the performance of curtain wall waterproof service life, as easy as rolling off a log generation seepage phenomenon in actual engineering.
Summary of the invention
The technical problem of solution required for the present invention has provided a kind of joint construction that increases the inboard waterproofing course of curtain wall.Do not adopt fluid sealant filling curtain wall plate slit waterproof sealing, and adopt the mode of curtain wall facade internal drainage to carry out effective waterproof.
In order to solve the problems of the technologies described above, the fundamental technics design of being taked is: a kind of thin metal plate curtain wall waterproofing node, comprise and forming curtain wall main joist that is connected with constructure body structure and the curtain wall secondary joist that is connected with outer curtain wall slab, described curtain wall secondary joist is installed on the described curtain wall main joist, it is characterized in that: between described curtain wall main joist and described curtain wall secondary joist, accompany one deck with outside the parallel airtight waterproof plate of curtain wall slab, described splash guard, be connected and fixed with bolt between curtain wall main joist and the curtain wall secondary joist, the outer end that described bolt connects described curtain wall secondary joist seals with fluid sealant, the anti-aqua regions of the size of described splash guard and outer curtain wall etc. are big, and the bottom of described splash guard is connected with outdoor aproll.
Be optimized for based on a kind of of such scheme: described splash guard is divided in layering, forms the district drainage face, and described splash guard is done apron flashing in described draining face bottom.
Utilize above-mentioned joint construction, can realize curtain wall slab rear side waterproof, with the existing waterproof thinking of " blocking up " of waterproof thinking replacement of " row " with fluid sealant.Simultaneously, curtain wall slab reliably can be connected with rear side building structure main body by splash guard.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing and application construction method.
Fig. 1 is the cross-sectional figure that main joist, secondary joist and splash guard adopt the bolt group to be connected.
The specific embodiment
The general installation constitution of curtain wall slab is at present: be made up of with the curtain wall secondary joist that is connected with outer curtain wall slab the curtain wall main joist that is connected with constructure body structure, described curtain wall secondary joist is installed on the described curtain wall main joist, and curtain wall slab is installed on the major structure of construction by secondary joist and main joist.Waterproof scheme of the present invention be between described curtain wall main joist and described curtain wall secondary joist, accompany one deck with outside the parallel airtight waterproof plate of curtain wall slab, be connected and fixed with bolt between described splash guard, curtain wall main joist and the curtain wall secondary joist, the outer end that described bolt connects described curtain wall secondary joist seals with fluid sealant, the anti-aqua regions of the size of described splash guard and outer curtain wall etc. are big, and the bottom of described splash guard is connected with outdoor aproll.Curtain wall slab itself can be got rid of a large amount of water outside the building, and small part water enters curtain wall slab inside by the slit of curtain wall slab.At this moment, water can vertically collect in the bottom of splash guard at the splash guard at curtain wall slab rear portion from top to down by lining, and splash guard is connected with outdoor water-proof.Like this, the water that the enters curtain wall inside discharge of just can taking advantage of a situation reaches the purpose of waterproof.
As shown in Figure 1: adopt the screw rod in the spot welding form set bolt group 4 on the main joist 1.Installation and processing circular hole on the splash guard 3, Circularhole diameter than screw diameter in the bolt group 4 slightly more greatly, screw rod passes the installation circular hole on the splash guard 3 in the bolt group 4, temporary fixed splash guard 3 is on main joist 1.Equally, installation and processing circular hole on secondary joist 2, Circularhole diameter than screw diameter in the bolt group 4 slightly more greatly, screw rod is passed in the installation circular hole on the secondary joist 2 in the bolt group 4, plain cushion and bullet pad in secondary joist 2 outside erection bolt groups 4, nut in the last erection bolt group 4, and fastening nut self-locking.The fluid sealant sealing is adopted in the nut outside in the bolt group 4, forms sealing termination 5, and anti-sealing enters inside by the installation slit of bolt, has guaranteed the continuity of waterproofing course waterproof sealing.
If the height of building is higher, but described splash guard is divided in layering, forms the district drainage face.Described splash guard is done apron flashing in described draining face bottom, and water just can be discharged water earlier in certain floor absolute altitude like this, only need do apron flashing on this draining absolute altitude layer, water is discharged get final product.
The way of apron flashing and splash guard bottom and the universal method that is being connected of outside aproll in the present engineering construction.
More than a kind of scheme that the embodiment of the invention provided is introduced in detail, for one of ordinary skill in the art, according to the thought of the embodiment of the invention, part in specific embodiments and applications all can change.In sum, this description should not be construed as limitation of the present invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.
