Abstract
The invention belongs to the field of curtain walls, and particularly relates to an improved locking piece connecting structure of a corner of a super-large curtain wall unit. The locking piece connecting structure of the corner of a curtain wall unit is simple in structure, small in amount of needed steel and capable of lowering the cost. The connecting structure comprises a curtain wall corner framework with corner vertical frames, wherein the upper and lower ends of the curtain wall corner framework are transverse frames. The connecting structure is characterized in that a middle transverse frame is arranged in the curtain wall corner framework, and the end part of the middle transverse frame is connected with the corner vertical frames; the upper and lower sides of the middle transverse frame in the curtain wall corner framework are respectively provided with a slant frame; one end of each slant frame is connected with the transverse frames, and the other end of each slant frame is fixedly connected with a joint between the middle transverse frame and each corner vertical frame; clamping grooves are formed at the positions, corresponding to the position of the middle transverse frame, of the opposite sides of two adjacent corner vertical frames of the curtain wall corner framework; the two corner vertical frames are connected into a whole body through locking pieces in the clamping grooves.
Description
Technical field
The invention belongs to the 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, occurred the cell curtain wall plate of some oversizes on market, for corner units, because general corner munnion is all to be with angledly, and the blast in bight is larger; Therefore, the corner munnion usually exists distortion excessive, or the situation such as insufficient strength.Especially in super large cell curtain wall plate, this problem is particularly evident.In order to realize the cell curtain wall plate of oversize, just need to constantly increase the Wind-Pressure Resistance requirement that the interior reinforcement steel core of munnion cross section and profile cavity meets cell curtain wall.
As shown in Figure 4, Figure 5, in the two corner munnions 4 at existing super large cell curtain wall board block corner place, all be provided with and strengthen steel core 10; Improve the intensity of corner munnion 4 by strengthening steel core 10; The required steel material of this form of structure is huge, is difficult to meet the requirement of cost control.
Summary of the invention
The present invention is directed to the problems referred to above, provide a kind of simple in structure, 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 end transom connected with the corner munnion in its structural feature curtain wall corner framework; The both sides up and down of the interior transom of curtain wall corner framework are provided with an 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 relative side of corner munnion of two adjacent curtain wall corner frameworks is provided with draw-in groove corresponding to the 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, by transom and the oblique frame connected with the corner munnion, forms the form of truss; And be provided with lock dog in the corner munnion, two corner munnions are fixed as one, thereby have significantly promoted the curtain wall unit resisting wind press capacity; Without being set in the corner munnion, the reinforcement steel core also can meet the requirement of Wind-Pressure Resistance; Therefore, the present invention compares with the syndeton of existing cell curtain wall corner, has saved a large amount of steel, has reduced cost of production.
In addition, the form that the draw-in groove of the present invention by lock dog and corner munnion matches, fix the corner munnion, simple in structure, easy for installation; Increase work efficiency.
Because unit plate wind pressure resistant strength of the present invention is large, therefore, be particularly suitable for superhuge unit plate, in the time of cost-saving, can also guarantee the safety of system.

In accompanying drawing, 1 is that curtain wall corner framework, 2 is that oblique frame, 3 is that transom, 4 is that corner munnion, 5 is that horizontal frame, 6 is that lock dog, 7 is that draw-in groove, 8 is that dop, 9 is that grab, 10 is the reinforcement steel core.
The specific embodiment
The present invention includes the curtain wall corner framework 1 with corner munnion 4, the curtain wall corner framework Shang Xia 1 two ends be horizontal frame 5, be provided with the end transom 3 connected with corner munnion 4 in curtain wall corner framework 1; The both sides up and down of the interior transom 3 of curtain wall corner framework 1 are provided with an end and are connected with horizontal frame 5, the oblique frame 2 that the other end is fixedly connected with corner munnion 4 connecting places 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, two corner munnions 4 corresponding to transom 3 positions and is 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 ends; Rational in infrastructure, be easy to install, and can guarantee 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 be controlled at the length that L/300+5=20.5mm(L is corner munnion 4), section bar intensity is 142N/mm
2.
Use existingly in the interior form of strengthening steel core 10 that arranges of corner munnion 4, as shown in Figure 4,5, the cross-sectional area of required reinforcement steel core 10 should be 160mm * 25mm=4000mm
2.
The moment of inertia of strengthening steel core 10 is L
x=329.77cm
4; L
y=544.4cm
4.
The section modulus of 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, and as shown in Figure 1, at the long intersecting parallels lock dog 6 of 100mm of the interior installation of draw-in groove 7 of I section position two corner munnions 4.
After in corner munnion 4, corresponding to transom 3 places, adding upper locking piece 6, being equivalent to has increased a fulcrum at corner munnion 4 span centres; Thus, can calculate in corner munnion 4 and strengthen steel core 10 without installing, thereby save a large amount of steel, be only 2.3kg in the amount of interior the used steel of said units curtain wall corner framework 1.
Be understandable that, above about specific descriptions of the present invention, only for being described, the present invention not is limited to the described technical scheme of the embodiment of the present invention, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the present invention, to reach identical technique effect; Use needs as long as meet, all within protection scope of the present invention.
