Description
Technical field
The invention belongs to building ancillary facility field, particularly, relate to a kind of deformation joint of roof cornice structure and job practices thereof that is used for waterproof, be specially adapted to adopt the large scale industry factory building and the public building of pressing steel plate roofing.
Background technology
Because receive the influence of factors such as variations in temperature, differential settlement and earthquake, the inside configuration of building will produce subsidiary stress, this kind stress can produce destructive influences to building structure.For reducing the influence that subsidiary stress produces building; When design, in advance the part of deformation sensitive is broken off; Building is divided into the several separate part, promptly reserves the structure slit, this kind slit promptly is called deformation joint; Can be to guarantee between each independent sector of building enough deformation spaces to be arranged not damaged or produce the crack because of the influence of factors such as variations in temperature, differential settlement and earthquake, thisly in large-scale industrial premises, use in a large number in the technology of reserving deformation joint between the building.
Yet owing to leave deformation joint between the building, if improper to the deformation joint processing, therefore the danger of have roof leaking, leaking out need be provided with cover plate and prevent that rainwater from getting into interior of building on the steel plate of large scale industry factory building roof.Yet at present for adopt the cover plate mode with the technology that prevents deformation joint and leak only on the top that the steel plate roofing is set; Then be negligent of considering for the sealing at deformation joint cornice position; Thereby make that enclosed construction is unreasonable and cause the sealing failure, and then make rainwater get into interior of buildings such as factory building.
For reaching the purpose that the deformation joint cornice is sealed, the measure that the existing building engineering adopts is: seal the deformation joint cornice in deformation joint cover plate bottom surface with the fixing individual plates of day trench cover upper surface.Yet this method can't adapt to the distortion of the stress steel work generation that produces because of factors such as variations in temperature, differential settlement and earthquakes, i.e. steel work distortion can make individual plates very easily be destroyed, thereby loses the sealing waterproof effect.
For reaching when the deformation joint cornice sealed, locking device can not produce distortion because of the stress that factors such as variations in temperature, differential settlement and earthquake produce, and at present domesticly mainly has a following related patent U.S. Patent No.:
Application (patent) number: 200620069546.3 patent names: building deformation slot set.The deformation slot set that this patent provides a kind of governor motion that constitutes by panel, pedestal, by spring and bolt to form.This patent can satisfy the requirement to building settlement distortion, displacement deformation and dilatation.Yet the deformation slot set that this patent provides is not protected the deformation joint cornice, is prone to make rainwater to get into interior of building from the deformation joint cornice, thereby has lost good waterproof effect.
Application (patent) number: 190610017588.9 patent names: bottom of the building face or deformation joint of roof are prevented water-leaking structure.It is a kind of through cover plate is set above deformation joint that this patent provides; Outside portion at deformation joint is provided with the gutter; Downside outer end at said cover plate is provided with the feet that is buckled in the gutter downwards; Waterproofing course is laid on surface in said gutter, and the place that said cover plate and feet bottom thereof contact with the gutter is provided with the watertight insulation that is positioned at the waterproofing course upper surface, and the bottom, gutter is provided with towards the structure of the drainage pipe of underdrainage system.
But the structure that this patent provides is to reach sealing deformation joint cornice through watertight insulation and waterproofing course are set between cover plate and drainage pipe; Thereby prevent that rainwater from getting into interior of building from the slit between cover plate and the gutter, its principle is tantamount to aforesaidly seal the deformation joint cornice in deformation joint cover plate bottom surface with the fixing individual plates of a day trench cover upper surface in fact.Therefore; Still can't solve the stress that produces because of factors such as variations in temperature, differential settlement and earthquakes misplaces the building of deformation joint both sides; And then make the watertight insulation between cover plate and the gutter take place to separate even come off; Cause watertight insulation to lose waterproof effect, make rainwater get into interior of building from the slit between cover plate and the gutter.
In addition, the architecture that this patent provides is complicated, and is too much with material, for example uses filleting rubber, galvanized sheet iron, pitch flax silk, decorative pattern ebonite board, aluminium alloys holder bar etc., makes manufacturing cost too high, do not meet the purpose of building a conservation-minded society.
Summary of the invention
For addressing the above problem; Thereby the object of the present invention is to provide a kind of fabric structure distortion simple in structure, that low cost of manufacture also can adapt to the stress generation to guarantee the stable deformation joint of roof structure of deformation joint structure long-term; In addition, the present invention also provides a kind of job practices of deformation joint of roof structure.
For achieving the above object, the technical scheme that the present invention adopts is:
A kind of deformation joint of roof cornice structure that is used for waterproof; Comprise deformation joint, be covered in the deformation joint cover plate on said deformation joint surface and cover the sky trench cover that is used for position, space between the gutter of draining in said deformation joint both sides, building roof on the building roof; It is characterized in that: the water sealing part that also comprises the fascia board that is fixed in said deformation joint cover plate bottom surface and be fixed in said day trench cover upper surface, said fascia board are positioned at the water sealing part outside and keep at a distance with said water sealing part.
