Detailed Description
The glass curtain wall shown in fig. 1 to 12 is similar to a conventional glass curtain wall in that the glass curtain wall of the present invention also includes a plurality of square curtain wall units 1, and the curtain wall units 1 are installed in a matrix on a keel frame of an exterior wall of a building, that is, the glass curtain wall of the present invention is also composed of a plurality of curtain wall units 1, which are also installed on the keel frame fixed on a facade of the exterior wall of the building, and the keel frame is usually made of a lightweight high-strength alloy material, which is the prior art and will not be described herein again. Compared with the traditional glass curtain wall, the invention mainly has the following differences:
firstly, the glass plate 2 structure of the glass curtain wall has great difference, and the traditional double-layer glass or multi-layer glass structure is changed. Specifically, as shown in fig. 5, 11 and 12, the curtain wall unit 1 includes a square glass plate 2, and the glass plate 2 includes a square support frame 3, and an outer layer glass 4 and an inner layer glass 5 mounted on the inner and outer sides of the support frame 3. The support frame 3, outer glass 4, correspond on the inner glass 5 and be provided with the multiunit bolt hole, bond through high strength glue between support frame 3 and inner glass 5, the outer glass 4 to through wearing to establish the fastening bolt 6 locking in the bolt hole. Through the double fixing mode, the combination of the inner layer glass 5, the outer layer glass 4 and the support frame 3 is realized, and the connection tightness and integrity are ensured.
And a heat insulation and noise reduction cavity 7 is formed among the inner surfaces of the support frame 3, the outer layer glass 4 and the inner layer glass 5. The interior of the heat insulation and noise reduction cavity 7 can form a vacuum-like environment, so that better heat preservation and noise reduction effects are achieved. Of course, when the width of the glass plate 2 is large, if the pressure in the thermal insulation and noise reduction cavity 7 is too large, the pressure difference between the inside and the outside is too large, which has a high requirement on the compressive strength of the inner glass 5 and the outer glass 4. Therefore, in order to ensure the strength of the entire glass sheet 2, the pressure in the heat-insulating noise-reducing chamber 7 may be increased appropriately to reduce the pressure difference. More particularly, the supporting frame 3 is internally provided with at least one layer of film 8 matched with the heat insulation and noise reduction cavity 7, and the film 8 divides the heat insulation and noise reduction cavity 7 into a plurality of layers of cavities which are distributed along the thickness direction of the heat insulation and noise reduction cavity 7 and are mutually independent. The film 8, instead of conventional glass, serves to reduce the overall weight and also to improve the functionality of the glass plate 2. For example: the film 8 can be an electrochromic film, a photochromic film and the like, and the color of the whole glass plate 2 is changed through the change of the color of the film 8, so that the performances of the glass curtain wall such as light shading performance, heat insulation performance and the like are improved.
The number of the film 8 is usually set to two layers, and of course, a plurality of layers can be set, and the more the number of the film 8 is, the more the film 8 can divide the heat insulation and noise reduction cavity 7 into more layers of cavities, so that the better noise reduction and heat insulation performance is achieved. However, in consideration of the thickness of the entire glass sheet 2, it is generally possible to provide two films 8 to meet most of the use requirements. As for the attachment mode of the film 8, the edge of the film 8 may be directly bonded and fixed to the inner wall of the supporting frame 3, but it is more preferable that, as shown in fig. 12, the supporting frame 3 is formed by overlapping two frame plates 9, and the two frame plates 9 are both square, and they are connected and overlapped to form the supporting frame 3. The inner side wall of the support frame 3 is also provided with a circle of annular clamping groove 10, the clamping groove 10 is composed of two half groove bodies, and the two half groove bodies are respectively positioned on the two frame plates 9. The clamping groove 10 is internally provided with a matched rubber clamping pad 11, the rubber clamping pad 11 is composed of three pad bodies, and the edges of two layers of films 8 are correspondingly clamped in gaps between two adjacent pads of the three pad bodies. According to the scheme, the edges of the thin film 8 are clamped tightly through the rubber clamping pads 11 in the clamping grooves 10 of the supporting frames 3, the thin film 8 is fixed, the installation is more convenient, and meanwhile, the stability of the thin film 8 is better. In order to further improve the sealing performance inside the heat insulation and noise reduction cavity 7, a filling groove is formed between the outer side wall of the supporting frame 3 and the outer layer glass 4 and between the outer side wall of the supporting frame and the inner layer glass 5, and a first sealant 12 is arranged in the filling groove.
The heat insulation and noise reduction cavity 7 of the glass plate 2 is divided by the film 8, so that a plurality of layers of partitions are formed in the heat insulation and noise reduction cavity 7, on one hand, compared with the form of a single heat insulation and noise reduction cavity 7, the sound insulation and noise reduction performance of the multi-layer partition form is improved, on the other hand, specific parameters of the film 8 and each layer of partition can be designed according to the actual use requirements of customers, and the performance of the glass plate 2 is further improved, for example: 1. a film 8 with special efficacy is used to protect from light; 2. the air density in each partition is differentiated to improve the sound insulation performance, and the like.

Since the structure is simple, the description is omitted in the present invention. The upper end of the bracket 14 is connected to the mounting frame 13 via a locking mechanism so as to be lockable and unlockable.
In this case, since the glass plate 2 needs to swing and the glass plate 2 has a certain thickness, if the upper and lower gaps of the glass plate 2 are too small, interference may be formed in the swinging process, and if the gaps are too large, continuity of the overall appearance of the glass curtain wall may be affected.

Thirdly, the mounting frame 13 of the present invention is unlocked or locked with the bracket 14 by using a locking mechanism, and the locking mode and structure are also a major core of the present invention. As shown in fig. 6, the mounting frame 13 is square, two hinge arms 27 are symmetrically arranged on two sides of the bottom of the mounting frame 13, and are hinged to the bracket 14 through the hinge arms 27, specifically, the hinge arms 27 can be hinged to the hinge joints 24 on the bracket 14, a base plate 28 is fixedly arranged below the upper cross beam of the mounting frame 13, two locking holes 29 are symmetrically arranged on two sides of the base plate 28, and the locking holes 29 are locking areas of the bracket 14 and the mounting frame 13.

A plurality of triangular reinforcing plates 45 are uniformly arranged between the side wall of the sliding tube 32 and the base plate 28 in an annular shape, so that the strength and the stability of the sliding tube 32 are ensured.
As shown in fig. 9, the locking mechanism includes an L-shaped locking tongue 33 fixedly provided at the upper end of the bracket 14, the locking tongue 33 is generally directly fixed to the connecting rail 0 above the bracket 14, and the locking tongue 33 is positioned opposite to the locking hole 29. The upper surface of the overhanging end of the lock tongue 33 is provided with a concave cavity 34 with a convex section, a transverse sliding plate 35 matched with the concave cavity 34 is arranged in the concave cavity 34, and the sliding plate 35 is in sliding fit with the concave cavity 34 and slides up and down in the concave cavity.
A first return spring 36 is provided between the bottom surface of the slide plate 35 and the bottom surface of the cavity 34. The first return spring 36 is used to drive the slide plate 35 to return within the cavity 34. The upper surface of the slide plate 35 is further provided with a first contact head 37, the first contact head 37 forming a sliding fit with the opening of the cavity 34. A locking head 38 is arranged in the locking hole 29, the lower surface of the locking head 38 and the upper surface of the first contact 37 are mutually matched inclined surfaces, and the inclined surfaces are inclined downwards from one side close to the bracket 14 to the other side. With this arrangement, as shown in fig. 9, when the latch 33 moves from left to right into the lock hole 29, the inclined surface on the first contact 37 contacts the inclined surface on the lock head 38, and at this time, the first contact 37 and the sliding plate 35 are pressed back into the cavity 34, and when the first contact 37 passes over the lock head 38, the sliding plate 35 and the first contact 37 are pushed up by the first return spring 36, and the first contact 37 is blocked by the lock head 38 and cannot be withdrawn. Meanwhile, the bracket 14 rotates to the vertical position, and the limit structure at the hinged position can limit the bracket 14 to continue rotating towards the direction close to the wall body, so that stable locking of the bracket 14 is formed.
As to how unlocking is achieved, the present invention adopts a mode that the height position of the locking head 38 in the locking hole 29 is changed through other structures. In other words, after the locking head 38 is lifted, no longer a barrier is formed with the first contact head 37, so that unlocking is achieved. Specifically, a sliding block 39 matched with the sliding cavity 30 is arranged in the sliding cavity 30, a second contact 40 is arranged at the top of the sliding block 39, and the bottom of the sliding block 39 is connected with the lock head 38 through a vertical rod 41 arranged in the vertical hole 31 in a penetrating manner. A second return spring 42 is sleeved outside the vertical rod 41, and the second return spring 42 is located between the bottom surface of the sliding block 39 and the bottom surface of the sliding cavity 30. A limiting cross bar 43 matched with the sliding tube 32 is arranged in the sliding tube 32.
The locking mechanism further includes an unlocking assembly capable of driving the spacing rail 43 to reciprocate within the sliding tube 32. As shown in fig. 9, when the inner end of the position-limiting crossbar 43 extends into the upper portion of the sliding cavity 30, the inner end of the position-limiting crossbar 43 can limit the height position of the second contact 40 and make the second return spring 42 in a compressed state, and the locking head 38 has a locking function on the locking tongue 33. As shown in fig. 10, when the inner end of the limiting cross bar 43 exits from the upper portion of the sliding cavity 30, the sliding block 39 can sequentially drive the vertical bar 41 and the lock head 38 to ascend under the resilience of the second return spring 42, so that the lock head 38 is separated from the first contact 37 on the lock tongue 33, at this time, the limiting cross bar 43 cannot form a barrier to the second contact 40, the lock head 38 ascends under the action of the second return spring 42, and no longer has the locking function on the lock tongue 33, and the unlocking is also realized.
In view of the flexible switching between the unlocked state and the locked state, the position-limiting crossbar 43 should have the function of actively driving the second contact head 40 to move downward, and for this purpose, the lower side of the inner end of the position-limiting crossbar 43 and the outer side of the top of the second contact head 40 are mutually inclined surfaces. Meanwhile, in order to avoid excessive transverse movement of the limiting cross bar 43, the upper part of the inner end of the limiting cross bar 43 is also provided with a limiting end strip 44 extending transversely.
The glass plate 2 of the curtain wall unit 1 is arranged on the bracket 14, and the bracket 14 is connected with the mounting frame 13 in a hinged mode, so that the bracket 14 can be opened firstly during installation or maintenance, and then the glass plate 2 is arranged on the bracket 14, so that the traditional standing installation mode is abandoned, the operation by workers is facilitated, and the construction difficulty and the construction cost are reduced. After the glass plate 2 is installed, the glass plate 2 and the bracket 14 are pushed to the installation frame 13 together, and automatic locking can be achieved. Meanwhile, when the locking mechanism adopted by the invention works, the first contact 37 can compress the first return spring 36 to retract into the cavity 34 when contacting with the lock head 38, and when the first contact 7 passes through the lock head 38, the first contact is ejected out of the cavity 34 under the action of the first return spring 36 and abuts against the lock head 38 to form locking, so that the glass plate 2 can be kept in a locking state as long as the lock head 38 is not unlocked. That is to say, the locking mechanism of the invention can not only ensure that the glass plate effectively enters the locking position, but also prevent the glass plate 2 from being opened by mistake under the action of external force, and ensure the stability of the installation of the glass plate 2 of the curtain wall unit 1.
As to how the movement of the spacing beam 43 is driven to effect switching of the mating relationship thereof with the second contact 40. The invention can adopt the following modes: the unlocking assembly comprises an end disc arranged at the outer end of the limiting cross rod 43, and the end disc is a magnetic disc body. The limiting cross rod 43 is further sleeved with a third return spring 48, the third return spring 48 is located between the end disc and the outer end of the sliding tube 32, and two ends of the third return spring are fixedly connected with the end disc and the outer end face of the sliding tube 32 respectively. When the third return spring 48 is in a natural state, the elastic force of the third return spring is enough to drive the inner end of the limiting cross bar 43 to extend into the sliding cavity 30 to limit the height position of the second contact head 40. During the use, through the magnetic attraction device absorption end disc in the glass board 2 outside, the end disc moves outwards and drives spacing horizontal pole 43 and remove. This is simple, but has the disadvantage that the resilience of the third return spring 48 is relatively large in order to ensure that the inner end of the retention bar 43 has sufficient retention force for the second contact 40. In this case, a large magnetic attraction is necessary to effect unlocking.
For this reason, as shown in fig. 9, the pressure of the high-pressure gas may be used to replace the rebound pressure limit of the third return spring 48, and the third return spring 48 only acts to return the piston disc 47 outward. Specifically, the outer end of the sliding tube 32 is further provided with a closed circular cylinder 46, and the cylinder 46 is communicated with the sliding tube 32. The outer end of the stop rail 43 extends into the cylinder 46 and is provided at the end with a piston disc 47 cooperating with the cylinder 46. The limiting cross rod 43 is further sleeved with a third return spring 48, and the third return spring 48 is located between the piston disc 47 and the inner surface of the inner end of the cylinder body 46. The outer end surface of the cylinder 46 is further provided with a one-way inflation tube 49 which is communicated with the interior of the cylinder 46 and can inflate high-pressure gas into the cylinder 46. The unlocking assembly can exhaust high-pressure gas in the cylinder 46, so that the piston disc 47 can be reset towards the outer end of the cylinder 46 under the elastic force of the third reset spring 48, and the inner end of the limiting cross rod 43 is driven to withdraw from the upper part of the sliding cavity 30. After adopting the scheme, high-pressure gas is filled into the cylinder body 46 through the one-way inflation tube 49, and sufficient pressure is kept, at the moment, the piston disc 47 is extruded, and the inner end of the limiting cross rod 43 is driven to be in contact with the second contact head 40. When the unlocking is needed, only the high-pressure gas in the cylinder body 46 needs to be discharged, and the third return spring 48 drives the piston disc 47 to move, so that the inner end of the limiting cross rod 43 is driven to move outwards.
The high-pressure gas can be discharged by providing a gas discharge pipe in the cylinder 46, providing a magnetically linked valve in the gas discharge pipe, and driving the gas discharge by a magnetic attraction device outside the glass plate 2. As shown in fig. 9, another alternative scheme may be that the upper and lower sides of the cylinder 46 are respectively provided with a side groove 50, and the upper and lower side walls of the cylinder 46 and the groove wall corresponding to the side groove 50 are respectively provided with a pair of corresponding first exhaust holes 51. The unlocking assembly comprises a sealing wedge block 52 which is clamped in the side groove 50 and forms sliding fit with the side groove 50, a second exhaust hole 53 is formed in the sealing wedge block 52, the inner end of the sealing wedge block 52 is connected with one end of a connecting rod 54, the other end of the connecting rod 54 penetrates through a guide hole formed in the bottom of the side groove 50 to be connected with a limiting disc 55, a fourth return spring 56 is sleeved outside the connecting rod 54, and the fourth return spring 56 is located between the limiting disc 55 and the bottom of the side groove 50. When the fourth return spring 56 is in a natural state, the second vent hole 53 of the sealing wedge 52 is staggered with the first vent hole 51. The unlocking assembly further comprises a driving disc 57 arranged on the front side of the outer end of the cylinder body 46, the driving disc 57 is connected with the outer end of the sealing wedge block 52, the driving disc 57 is a magnetic disc body, and the driving disc 57 is connected with the sealing wedge block 52 through a C-shaped connecting piece 59.
When the air-tight sealing device is used, an operator attracts the driving disc 57 through the magnetic adsorption device outside the glass plate 2, the driving disc 57 moves to drive the sealing wedge block 52 to move, as shown in fig. 10, the first exhaust hole 51 is communicated with the second exhaust hole 53, and then high-pressure air in the cylinder body 46 can be exhausted. In order to ensure the sealing performance between the sealing wedge 52 and the side groove 50 in the locked state, the groove cavity of the side groove 50 is gradually reduced from the outer end to the inner end, the sealing wedge 52 is gradually reduced from the outer end to the inner end, and the surface of the sealing wedge 52 is provided with a rubber layer. Since the one-way inflation tube 49 is usually disposed at the end of the cylinder 46, in order to avoid the interference of the driving disk 57 with the one-way inflation tube 49, the center of the driving disk 57 is provided with a relief hole 58, and the position of the relief hole 58 is opposite to the one-way inflation tube 49.
