Description

Base section bar subassembly and glass curtain wall system for glass curtain wall system

Technical Field

The invention relates to a base profile assembly for a glass curtain wall system and the glass curtain wall system, in particular to a base profile assembly which is fixedly arranged on a main frame of the glass curtain wall system (particularly a fireproof glass curtain wall system) or a glass partition system in a superposition manner and is used for clamping and fixing or supporting a glass plate, and the glass curtain wall system adopting the base profile assembly.

Background

Glass curtain walls in various buildings are generally realized by mounting and fixing glass panels to a main frame for mounting and fixing glass panels in a building which is previously mounted and fixed (or pre-buried). For glass curtain wall with fireproof function, the main frame needs to adopt steel profile (melting point is higher than 1200 ℃ and fireproof paint is coated if necessary) to meet the requirements of bearing capacity, wind pressure resistance mechanical property, fireproof property and the like. Thus, what is known as a glass curtain wall system (including fire-resistant glass curtain wall systems) includes: a main frame for installing and fixing a glass plate on a building, a glass plate, a fixing member for installing and fixing the glass plate on the main frame, a supporting member for supporting the glass plate on the main frame, a sealing member for filling gaps between the glass plate and the main frame and between the fixing member and the supporting member, and the like are installed and fixed (or pre-buried). Wherein the fixing member generally includes a clamping plate member clamping the glass sheet, and a fastening member fastening the clamping plate member to be fixedly mounted to the main frame in a state where the clamping plate member clamps the glass sheet. The support member generally includes a support plate member that receives and supports the glass sheet, and a support plate fixing member that fixes the support plate member to the main frame. In addition, the main frame is generally composed of a vertical beam frame (parallel to the building height direction) and a cross beam frame (perpendicular to the vertical beam frame). Thus, the securing members generally clamp the glass sheets together with the vertical and horizontal beam frames, and the support members generally receive the support glass sheets together with the horizontal beam frames.

In the prior art fire-resistant glass curtain wall system, the vertical beam frame and the beam frame of the main frame are made of steel member profiles (including various rectangular steel pipes, H-type steel, T-type steel, i-type steel, etc.), and the structure for clamping and fixing the glass plate is implemented by using screws or bolts attached and fixed to the main frame (vertical beam frame and beam frame), specifically, as shown in fig. 1 (drawing by using recessed boss tapping screws), the structure for clamping and fixing the glass plate G includes bosses 72 of inner holes 71 formed on the main frame (vertical beam frame and beam frame) 70 for screwing screws 80 as fastening members, and when fixing the glass plate G, the glass plate G is abutted against abutting surfaces 73 of the main frame (vertical beam frame and beam frame) 70, and then the screws 80 passing through holes (not shown) in the clamping plate member 90 are screwed into the inner holes 71 in a state where the outer cover member 90 is clamped together with the main frame 70, the inner holes 71 are slightly smaller in diameter than the outer diameters of the screws 80, that the outer cover 80 is self-tapping screws 80 are adopted, and the glass plate G is fastened to the inner walls 80 of the main frame (frame and the inner walls 80 are screwed to the inner walls 80 are clamped by the screws 80 and the main frame 70 by screwing together with the screws 80. With this structure for clamping and fixing the glass sheet, since the main frame 70 is required to use an integral profiled steel section (typically a closed profiled straight welded pipe), there are the following problems. (1) The integral special-shaped steel section is required to adopt special-shaped forming dies (a set of tens of forming dies are required for one section shape, specification and wall thickness), the investment of forming equipment (roll forming and high-frequency welding) and special dies is very high, the debugging time for replacing the dies (changing production) is long, the debugging failure rate is high, and the relative product cost is high; (2) The integral special-shaped steel section is limited in a small range (such as 2.3-2.5 mm; 2.7-3.0 mm) due to the shape, size and material characteristics, and the bending modulus can be improved only by increasing the size of the bending resistance direction, so that the number of special forming dies is increased, and the cost is increased; (3) Special materials (such as Q355E, Q460E, SS, SS316 and the like) required by special occasions, the integral special-shaped steel section is difficult to realize molding or meets the design requirement; (4) The self-tapping screw structure is used for clamping and fixing the glass plate, and because the engagement (screwing) strength between the screw 80 and the inner wall of the inner hole 71 is limited, the related requirements cannot be met in the case of high fireproof requirements, namely, large thickness (large number of blocks) of the glass plate G.

In view of the above problems, in the glass curtain wall system of the related art, there has been a case of adopting what is called a superimposed clamp fixing structure as shown in fig. 2. Specifically, as shown in fig. 2, the base profile 100 is formed separately from the base profile formed directly on the vertical beam frame and the horizontal beam frame, and the boss 102 for clamping the inner hole 101 for fixing the glass sheet is formed not directly on the main frame (vertical beam frame and horizontal beam frame) 104 but on the base profile 100. Although such a structure solves the problem of complicated process and high cost caused by the need of forming the main frame (the vertical beam frame and the cross beam frame) by adopting the deformed steel structure in the prior art, the structure still adopts the self-tapping screw 105 to clamp and fix the glass plate G, so that the base profile or the base profile assembly with such a structure cannot meet the related requirements even in the case of high fireproof requirements, namely the large thickness (large number of blocks) of the glass plate G.

That is, when two of the sloping side portions 22c of the head portion 22 are in contact engagement with the inner surfaces 11f of the two sloping side portions 11c of the engagement rail groove 11, the head portion 22 is slidable between the bottom portion 11a and the opening portion 11b of the engagement rail groove 11, while the head portion 22 cannot be exposed from the opening portion 11b to the outside of the engagement rail groove 11 because the side length W4 is greater than the inner groove width W2, and the head portion 22 is in wedge engagement with the inner surface 11 f.

The lock washer 30 is a profile having a trapezoid shape in its longitudinal section and having one bottom edge portion, which is a top plate portion 31 shown in fig. 7 (a) and (b), and two 3 rd oblique edge portions, which are engagement edge portions 32 extending along both ends of the top plate portion 31, and which are integrally formed by bending or pressing a steel plate. The top plate 31 is provided with a pad through hole 31a, and the diameter D2 of the pad through hole 31a is set to be slightly larger than the diameter D1 of the screw 21. When the width at the intersection of the inner surface 32a of the engaging side portion 32 and the bottom surface 31b of the top plate portion 31 is set to W6 and the angle between the inner surfaces 32a of the two engaging side portions 32 is set to θ4, in the present embodiment, W6 is set to be equal to or slightly larger than W3 and θ4 is set to be equal to θ2. That is, when the inner surfaces 32a of the engaging side portions 32 of the lock washer 30 as the two sloping side portions are brought into contact engagement with the outer surfaces 11g of the two sloping side portions 11c of the engaging rail groove 11, the lock washer 30 is engaged with the outer surfaces 11g of the two sloping side portions 11c of the engaging rail groove 11 along the outer surfaces 11g of the two sloping side portions 11c of the engaging rail groove 11. Further, the length of the lock washer 30 in the longitudinal direction of the base profile 10 is set to L2.

The lock connection screw 40, as shown in fig. 8, has an inner screw hole 41 penetrating the lock connection screw 40, a part of the inner screw hole 41 in the axial direction is for screwing with the external screw thread 23 of the screw portion 21, and the other part of the inner screw hole 41 in the axial direction is for screwing with a screw M3 described later. That is, the inner diameter of the inner screw hole 41 is the same as the outer diameters of the male screw 23 and the screw M3, that is, the inner screw hole is of a size to be screwed with each other. In addition, the outer diameter D3 of the lock coupling screw 40 is set to be larger than the diameter D2 of the pad through hole 31 a. The axial length of the locking connection nut 40 may be set to various lengths according to the total thickness of the glass sheet G to be installed in a clamped manner.

The base profile assembly 2 for a glass curtain wall system of the present invention has: base section bar 10, tensioning screw 20, locking support backing plate 50 and locking connection swivel nut 40.

The base profile assembly 2 is constructed in the same manner as the base profile assembly 1 except that the locking support pad 50 is different from the locking pad 30 in the base profile assembly 1, namely the base profile 10, the tensioning screw 20, and the locking connection screw sleeve 40. Therefore, for convenience of explanation, only the structure of lock support shim plate 50 will be explained, and explanation of other components will be omitted.

The locking support pad 50, as shown in fig. 9 and 10, has a locking pad part 51 and a support plate 52 for supporting a glass plate. The locking pad part 51 has the same shape and structure as the locking pad 30, and is formed by bending, punching or forging a steel plate, and has a bottom edge part, which is a top plate part 53 as shown in fig. 9 and 10, and two oblique edge parts 3, which are engagement edge parts 54 extending along both ends of the top plate part 53, respectively. Further, the top plate 53 is provided with a pad through hole 53a, and the diameter D4 of the pad through hole 53a is set to be slightly larger than the diameter D1 of the screw 21. When the width at the intersection of the inner surface 54a of the engaging side portion 54 and the bottom surface 53b of the top plate portion 53 is set to W7 and the angle between the inner surfaces 54a of the two engaging side portions 54 is set to θ5, in the present embodiment, W7 is set to be equal to or slightly larger than W3 and θ5 is set to be equal to θ2. That is, when the inner surfaces 54a of the engaging side portions 54 of the lock stay plate 50 as the two sloping side portions are brought into contact engagement with the outer surfaces 11g of the two sloping side portions 11c of the engaging rail groove 11, the lock stay plate 50 is engaged with the outer surfaces 11g of the two sloping side portions 11c of the engaging rail groove 11 along the outer surfaces 11g of the two sloping side portions 11c of the engaging rail groove 11. Unlike locking support shim plate 30, locking support shim plate 50 also has a support plate 52 for supporting a glass sheet. The support plate 52 is provided on a portion of the top plate 53 near one side of one of the two engagement side portions 54, and is erected on the top plate 53 at right angles to the top plate 53 in a direction opposite to the extending direction of the engagement side portion 54. In addition, when the length of the lock stay plate 50 in the longitudinal direction of the base profile 10 is set to L3. In this embodiment, the present invention is applicable to a portable electronic device. The number of the pad through holes 53a provided in the top plate 53 is 2 times the number of the L2, and two pad through holes 53a are provided at a predetermined distance. However, the present invention is not limited thereto, and as another embodiment, the L3 and the L2 may be equal to each other, or the L3 may be 2 times or more the L2. In response to this, the top plate 53 has one or a plurality of pad through holes 53a spaced apart from each other. The support plate 52 may be integrally formed with the locking pad 51, may be erected on the top plate 53 by welding or the like, and may have an angle other than 90 degrees (for example, an angle of 75 to 115 degrees) with respect to the top plate 53. Since the locking support pad 50 has the locking pad part 51 and the support plate 52 for supporting the glass plate, the locking support pad 50 has a support function for supporting the glass plate in addition to the same locking function as the locking pad 30.

Hereinafter, a method of mounting the

base profile assemblies

1 and 2 for a glass curtain wall system of the present invention to the curtain wall main frame K will be described with reference to fig. 11 and 12.

First, with respect to the base profile 10, after the outer surface 11d of the bottom 11a of the engagement rail groove and the

outer surfaces

12c, 12c of the 1

st extension portions

12a, 12a provided on the same plane are attached to the mounting surface K1 of the curtain wall main frame K, the screw M1 is screwed to the curtain wall main frame K through the 2 nd base through

holes

12d, 12d. Then, the head 22 of the tension screw 20 is fitted into the engagement rail groove 11 from either one of the two ends of the base profile 10 in the direction of arrow P shown in fig. 4, and the screw portion 21 is positioned outside the opening 11b. After the tension screw 20 is moved to the installed position in the engagement rail groove 11, the screw M2 is screwed to the curtain wall main frame K through the 1 st base through hole 11e (see fig. 3). Next, the lock base plate 30 or the lock support base plate 50 is engaged with the base profile 10 by bringing the inner surfaces 32a of the two engaging side portions 32 or the inner surfaces 54a of the two engaging side portions 54 into contact with the outer surfaces 11g of the two sloping side portions 11c of the engaging rail groove 11 in a state in which the base plate through hole 31a or the base plate through hole 53a is penetrated by the screw portion 21. Then, the inner screw hole 41 of the locking connection screw 40 is screwed with the outer screw thread 23 of the screw portion 21, and at this time, the head 22, that is, the tension screw 20 is locked in the engagement guide groove 11 with the screwing of the inner screw hole 41 of the locking connection screw 40 with the outer screw thread 23 of the screw portion 21. At the same time, the locking pad 30 or the locking support pad 50 is locked between the clamping rail groove 11, i.e. the base profile 10, and the locking connection screw 40. Since the head 22 is in wedge-shaped engagement with the inner surface 11f, the tighter the locking connection nut 40 is screwed relative to the tensioning screw 20, the tighter the wedge-shaped engagement of the head 22 with the inner surface 11f, i.e. the more tightly the tensioning screw 20 is secured to the base profile 10.

The invention also provides a glass curtain wall system which comprises the base profile assembly 1 or/and the base profile assembly 2 which are fixed on the main frame K of the curtain wall and are used for clamping and fixing or supporting the glass plate G, an outer cover plate 60 which is used for clamping the glass plate G, and a fastening screw M3 which is used for fastening the outer cover plate 60 on the base profile assembly 1 through an inner screw hole 41 which is screwed into the locking connecting screw sleeve 40 in the state of clamping the glass plate G.

Hereinafter, a glass curtain wall system in which a glass panel G is mounted by using the base profile assembly 1 or/and the base profile assembly 2 of the present invention will be described with reference to fig. 11 and 12. In this embodiment, installation and installation of a glass curtain wall system of only one curtain wall unit will be described.

As shown in fig. 11, the curtain wall unit includes a curtain wall pillar K2 and curtain wall cross beams K3, K4, wherein the curtain wall cross beam K3 is a middle and lowermost cross beam, and the curtain wall cross beam K4 is an uppermost cross beam, and when the glass plate G is mounted on the curtain wall main frame K, only the glass plate G needs to be clamped tightly on the curtain wall pillar K2 and the curtain wall cross beam K4, and not only the glass plate G needs to be clamped tightly but also the glass plate G needs to be supported on the curtain wall cross beam K3. Therefore, on the curtain wall upright column K2 and the curtain wall cross beam K4, only the base section bar assembly 1 with the locking backing plate 30 is used for clamping and fixing the glass plate G, and on the curtain wall cross beam K3, not only the base section bar assembly 1 with the locking backing plate 30 is used for clamping and fixing the glass plate G, but also the base section bar assembly 2 with the locking supporting backing plate 50 is used for supporting the glass plate G. Then, as shown in fig. 12, on the curtain wall cross beam K3, a plurality of base profile assemblies 1 having locking mats 30 and base profile assemblies 2 having locking support mats 50 are alternately provided, and the spacing and number of the

base profile assemblies

1 and 2 can be freely selected and combined according to the thickness, weight, and size of the curtain wall unit of the different glass sheets G, without being particularly limited thereto.

The mounting of the base profile assembly 1 and the base profile assembly 2 to the curtain wall cross beam K3 will be described below with reference to fig. 13 and 14. The method of installing the base profile assembly 1 on the curtain wall pillar K2 and the curtain wall cross beam K4 is basically the same as the method of installing the base profile assembly 1 on the curtain wall cross beam K3, and a detailed description thereof will be omitted.

Fig. 13 is a cross-sectional view taken along line B-B of fig. 12. First, as shown in fig. 13 and 14, the base profile assembly 1 is mounted to the curtain wall cross beam K3 according to the above-described mounting method of the base profile assembly 1 to the curtain wall main frame K, then, a sealing strip F1 (may also be a fire sealing strip) is provided by hooking with the 2

nd extensions

12b, 12b of the base profile 10 of the base profile assembly 1, next, a glass plate G (may be a plurality of overlapped glass plates) to be mounted is passed through the mounting hole G1 by the locking connection screw sleeve 40, and then, as shown in fig. 13, the outer cover plate 60 is screwed into the inner screw hole 41 of the locking connection screw sleeve 40 by a screw M3 and tightened, thereby fixing the glass plate G to the curtain wall cross beam K3. Finally, a decorative cover B is covered on the outer surface of the outer cover plate 60. The outer cover 60, the decorative cover B, the sealing strip F1, the sealing strip F2, and the like may be the same as those in the prior art, and are not particularly limited herein.

Fig. 15 is a cross-sectional view taken along line C-C of fig. 12. As shown in fig. 15 and 16, first, the base profile assembly 2 is mounted to the curtain wall cross beam K3 by the above-mentioned mounting method of the base profile assembly 1 to the curtain wall main frame K, at this time, in a state where the support plate 52 of the lock support cushion 50 is located at the upper position of the support glass plate G, a sealing strip F1 (may also be a fire-proof sealing strip) is provided by hooking with the 2

nd extensions

12b, 12b of the base profile 10 of the base profile assembly 2, and then, the glass plate G (may be a glass plate formed by overlapping a plurality of glass plates) to be mounted is passed through the mounting hole G1 by the lock connection screw 40 while the support plate 52 supports the glass plate G at least in a state where the sealing strip F3 (may also be a fire-proof sealing strip) is sandwiched between the mounting hole G1 and the support plate 52. Then, as shown in fig. 15, the outer cover 60 is screwed into the inner screw hole 41 of the locking connection screw sleeve 40 by the screw M3 in a state of clamping the sealing strip F2 (which may be a fire-proof sealing strip), thereby clamping and fixing the glass sheet G to the curtain wall cross beam K3 while being supported to the curtain wall cross beam K3 by the base profile assembly 2. Finally, a decorative cover B is covered on the outer surface of the outer cover plate 60. The outer cover 60, the decorative cover B, the sealing strip F1, the sealing strip F2, the sealing strip F3, and the like may be the same as those in the prior art, and are not particularly limited herein.

Therefore, the glass plate can be firmly installed and fixed on the main frame K of the curtain wall by adopting the superimposed base profile assembly, and compared with the prior art, the glass curtain wall system adopting the base profile assembly has the advantages that the profile is not adopted to form the main frame or the base profile of the curtain wall, the boss with the screw hole for screwing and fixing the tapping screw is not formed on the main frame or the base profile of the curtain wall, namely, the tapping screw structure is not adopted, so that the cost can be reduced, the glass plate can be reliably and firmly clamped and fixed, and the effect is more remarkable particularly for the fireproof glass curtain wall system.

In the above embodiment, the cross-sectional shape of the head 22 is formed in a square shape, and the cross-sectional shape thereof may be formed in a rectangular shape, as long as it has two parallel sides having the same side length as the square side. The shape of the edge that does not fit the inner surface 11f of the two sloping sides 11c of the engaging rail groove 11 is not limited, and may be, for example, a curved edge or a bent edge.

In addition, not every place of the base profile assembly supporting the glass panel G is required to be clamped and fixed, for example, as shown in fig. 17, instead of the tension screw 20 and the lock connection screw sleeve 40, the base profile 10 and the lock support pad 50 are fixedly mounted to the curtain wall cross beam K3 using a bolt structure M4 or a screw (not shown).

The base profile 10 may be formed by forging or casting, or may be made of a material other than a steel plate having a desired strength.

In addition, the materials and thicknesses of the materials used for the base profile 10, the tension screw 20, the locking backing plate 30 or the locking support backing plate 50, and the locking connection screw sleeve 40 are selected according to the total thickness of the glass sheets in the glass curtain wall to be installed, and are not particularly limited herein.
