Description
Technical field
The present invention relates to a kind of linkage, particularly about a kind of linkage of sectional type fire resisting shutter.
Background technology
The fire prevention that fire curtain is widely used in all types of industries such as market, hotel, hospital, museum, exhibition hall, cinema, airport, highrise building, factory and mine and civilian construction cuts off the district.When fire took place, it can prevent fires effectively, at a distance from cigarette with suppress fire spread, to reach protection evacuating personnel and the purpose that ensures the security of the lives and property, was indispensable fireproofing in the modern architecture.
At present, existing fire curtain great majority are all-in-one-piece steel roller shutter, and the shortcoming of its existence is that thermal insulation, corrosion resistance and moisture resistance are not good enough, and curtain face weight is big, and it is big to take up room, and install and carry very inconvenient.The fire curtain that also has is all-in-one-piece non-woven cloth matter roller shutter; Though it has solved steel roller shutter thermal insulation, corrosion resistance and the not good enough problem of moisture resistance, when certain of curtain face is damaged, must change monoblock curtain face; Not only change inconvenience, and improved cost.The non-woven cloth matter fire curtain that also has adopts the segmented design; Each section curtain face links together with screw or fastening devices; Because screw on the curtain face or fastening devices are to be provided with at interval; Therefore will inevitably there be the slit in the junction of curtain face and curtain face, thereby has influenced the fire-proof smoke insulation performance of fire curtain greatly.In a single day simultaneously, adopt screw or fastening devices to connect also inconvenient installation and removal, and have certain section curtain face to damage, change still very inconvenient.
Summary of the invention
To above problem, the purpose of this invention is to provide a kind of linkage of the sectional type fire resisting shutter that is easy for installation and removal.
For realizing above-mentioned purpose; The present invention takes following technical scheme: a kind of linkage of sectional type fire resisting shutter; It is characterized in that: it comprises a female hook of a Γ shape and a L shaped sub-hook, and the top of said female hook has outwards rotating outer hook, and the bottom of said sub-hook has inwardly rotating interior hook; And the radius of curvature of said outer hook is a bit larger tham the radius of curvature of said interior hook, and the interior hook of said sub-hook is plugged in the outer hook of said female hook by an end of said female hook; Be provided with some connecting screw rods on the straight plate of said female hook and sub-hook, the straight plate inboard of said female hook and sub-hook is respectively arranged with clamping plate through said connecting screw rod.
The cross section of said clamping plate is c-shaped.
The material of said female hook, sub-hook and clamping plate adopts that laths of metal is rolling to form.
The interior hook of said sub-hook is hollow or solid.
Said female hook or sub-hook are fixed on the upper end or the lower end of curtain face.
The said female hook or the sub-hook of said curtain face upper end link to each other with power transmission shaft.
The said female hook or the sub-hook of said curtain face lower end link to each other with the underseal beam.
The present invention is owing to take above technical scheme; It has the following advantages: 1, the present invention includes a female hook and a sub-hook, the top of female hook has outwards rotating outer hook, and the bottom of sub-hook has inwardly rotating interior hook; And the radius of curvature of hook in the radius of curvature of outer hook is a bit larger tham; Thereby the interior hook of sub-hook can be plugged in from an end of female hook the outer hook of female hook, when the present invention is used in sectional type fire resisting shutter, only need female hook is fixed on the upper end or the lower end of curtain face; Sub-hook is fixed on the lower end or the upper end of curtain face; Multistage curtain face links into an integrated entity through female hook and sub-hook, does not have the slit between each section curtain face, has therefore strengthened the fire-proof smoke insulation performance of sectional type fire resisting shutter greatly.Simultaneously, when wherein a certain section curtain face damages, only need to change this section curtain face and get final product, greatly reduce replacement cost, and change also very convenient.2, the present invention can be used for connecting cloth matter sectional type fire resisting shutter, compares with common steel roller shutter, and not only weight reduces greatly, convenient in carrying, and also thermal insulation, corrosion resistance and moisture resistance are preferable, are applicable to nearly all ambient conditions, and durable in use.In sum, the present invention is simple in structure, and installation and removal are convenient, and cost is lower, can be widely used on the various sectional type fire resisting shutters.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is carried out detailed description.
Like Fig. 1～shown in Figure 2; The present invention includes a female hook 1 of a Γ shape and a L shaped sub-hook 2; The top of female hook 1 has the outer hook 11 of outside rotating arc; The bottom of sub-hook 2 have inwardly rotating in hook 21, and the radius of curvature of outer hook 11 is a bit larger tham the radius of curvature of interior hook 21, thereby the interior hook 21 of sub-hook 2 can be plugged in the outer hook 11 of female hook 1 from an end of female hook 1.Be provided with some connecting screw rods 3 on the straight plate of female hook 1 and sub-hook 2, the straight plate inboard of female hook 1 and sub-hook 2 is respectively arranged with a C clamp plate 4 through connecting screw rod 3.
As shown in Figure 3, the present invention only needs female hook 1 is fixed on the upper end or the lower end of curtain face 5 through connecting bolt 3 and clamping plate 4 in use, sub-hook 2 is fixed on the lower end or the upper end of curtain face 5 through connecting bolt 3 and clamping plate 4.When needs are installed fire curtain; As long as need the female hook 1 on each section curtain face 5 be connected with sub-hook 2 successively; And the female hook 1 or the sub-hook 2 of curtain face 5 upper ends linked to each other with power transmission shaft; Female hook 1 of curtain face 5 lower ends or sub-hook 2 (not shown) that links to each other with the underseal beam can form a complete fire curtain, so installation or removal is extremely convenient.When wherein one section curtain face 5 damages, the curtain face 5 that also can more renew easily.Simultaneously, because each section curtain face 5 is one section one a section independently curtain face, it is convenient especially therefore to carry.
In the foregoing description, the material of female hook 1, sub-hook 2 and clamping plate 4 can adopt that laths of metal is rolling to form.
In the foregoing description, the interior hook 21 of sub-hook 2 can be for hollow or solid.
In the foregoing description, curtain face 5 can adopt refractory fiber cloth, refractory fiber blanket or fire-retardent fiber felt-rug etc.
The present invention only describes with the foregoing description; The structure of each parts, the position is set and connects and all can change to some extent; On the basis of technical scheme of the present invention; All improvement and equivalents of individual component being carried out according to the principle of the invention all should not got rid of outside protection scope of the present invention.
