Description
Technical field
The invention belongs to curtain wall field, specifically, the present invention relates to a kind of improvement of super large curtain wall unit corner lock dog syndeton.
Background technology
In recent years, market has occurred the cell curtain wall plate of some oversizes, for corner units, because general corner munnion is all that band is angled, and the blast in bight is larger; Therefore, it is excessive usually to there is distortion in corner munnion, or the situation such as insufficient strength.Especially, in oversized unit curtain wall plate, this problem is particularly evident.In order to realize the cell curtain wall plate of oversize, just need constantly to increase reinforcement steel core in munnion cross section and profile cavity to meet the Wind-Pressure Resistance requirement of cell curtain wall.
As shown in Figure 4, Figure 5, in two corner munnions 4 of existing oversized unit curtain wall plate corner, be all provided with and strengthen steel core 10; The intensity of corner munnion 4 is improved by strengthening steel core 10; Steel material needed for this form of structure is huge, is difficult to the requirement meeting cost control.
Summary of the invention
The present invention is directed to the problems referred to above, provide a kind of structure simple, required steel material is few, the curtain wall unit corner lock dog syndeton reduced costs.
For reaching above-mentioned purpose of the present invention, the present invention adopts following technical scheme: the present invention includes the curtain wall corner framework with corner munnion, the upper and lower two ends of curtain wall corner framework are horizontal frame, are provided with the transom that end is connected with corner munnion in its structural feature curtain wall corner framework; In curtain wall corner framework, the both sides up and down of transom are provided with one end and are connected with horizontal frame, the oblique frame that the other end is fixedly connected with corner munnion connecting place with transom; The side that the corner munnion of two adjacent curtain wall corner frameworks is relative is provided with draw-in groove corresponding to transom position, and two corner munnions are integrally connected by the lock dog in draw-in groove.
Beneficial effect of the present invention: the present invention passes through, with the connected transom of corner munnion and oblique frame, to form the form of truss; And lock dog is provided with in corner munnion, two corner munnions are fixed as one, thus significantly improve curtain wall unit resisting wind press capacity; The requirement that steel core also can meet Wind-Pressure Resistance is strengthened without the need to arranging in corner munnion; Therefore, the present invention, compared with the syndeton of existing cell curtain wall corner, saves a large amount of steel, reduces cost of production.
In addition, the form that the present invention is matched by the draw-in groove of lock dog and corner munnion, fixes corner munnion, and structure is simple, easy for installation; Increase work efficiency.
Because invention unit plate wind pressure resistant strength is large, therefore, is particularly suitable for superhuge unit plate, while cost-saving, the safety of system can also be ensured.

In accompanying drawing 1 be curtain wall corner framework, 2 for oblique frame, 3 for transom, 4 for corner munnion, 5 for horizontal frame, 6 for lock dog, 7 for draw-in groove, 8 for dop, 9 for grab, 10 for strengthen steel core.
Detailed description of the invention
The present invention includes the curtain wall corner framework 1 with corner munnion 4, curtain wall corner framework about 1 two ends are horizontal frame 5, are provided with the transom 3 that end is connected with corner munnion 4 in curtain wall corner framework 1; In curtain wall corner framework 1, the both sides up and down of transom 3 are provided with one end and are connected with horizontal frame 5, the oblique frame 2 that the other end is fixedly connected with corner munnion 4 connecting place with transom 3; The side that the corner munnion 4 of two adjacent curtain wall corner frameworks 1 is relative is provided with draw-in groove 7 corresponding to transom 3 position, and two corner munnions 4 are integrally connected by the lock dog 6 in draw-in groove 7.
Described lock dog 6 is set to intersecting parallels, and described draw-in groove 7 is provided with grab 9 corresponding to the dop 8 of intersecting parallels lock dog 6 end; Rational in infrastructure, be easy to install, and can ensure that corner munnion 4 can reliably be integrally connected.
Embodiment: unit plate width W=3.6m; Height H=4.64m; Blast p=1.6/-3.3kPa; Wind load coefficient gamma f=1.6.
According to the requirement of CWCT, the deflection of corner munnion 4 should control to be the length of corner munnion 4 at L/300+5=20.5mm(L), section bar intensity is 142N/mm
2.
Use the existing form arranging reinforcement steel core 10 in corner munnion 4, as shown in Figure 4,5, then the cross-sectional area of required reinforcement steel core 10 should be 160mm × 25mm=4000mm
2.
The moment of inertia strengthening steel core 10 is L
x=329.77cm
4; L
y=544.4cm
4.
The section modulus strengthening steel core 10 is W
x=56.23cm
3; W
y=76.61cm
3.
Finally calculate, existing corner curtain wall construction steel use amount is 292kg.
And use curtain wall corner framework 1 structure of the present invention, as shown in Figure 1, the long intersecting parallels lock dog 6 of a 100mm is installed in the draw-in groove 7 of I position two corner munnion 4.
After add upper locking piece 6 corresponding to transom 3 place in corner munnion 4, be equivalent to add a fulcrum at corner munnion 4 span centre; Thus, can calculate in corner munnion 4 and strengthen steel core 10 without the need to installing, thus save a large amount of steel, the amount of the steel used in said units curtain wall corner framework 1 is only 2.3kg.
Be understandable that, above about specific descriptions of the present invention, the technical scheme described by the embodiment of the present invention is only not limited to for illustration of the present invention, those of ordinary skill in the art is to be understood that, still can modify to the present invention or equivalent replacement, to reach identical technique effect; Needs are used, all within protection scope of the present invention as long as meet.
