Description

Technical Field

[0001] The invention relates to the technical field of curtain wall construction, in particular to a super-large plate glass curtain wall crossbeam connection structure and a construction method. Background Art

[0002] Glass curtain wall refers to the building's external protective structure or decorative structure that has a certain displacement capacity relative to the main structure and does not share the effects on the main structure. The wall has two types of glass: single-layer and double-layer. Glass curtain wall is a beautiful and novel way to decorate building walls, and is a prominent feature of the modernist high-rise building era.

[0003] Patent publication number CN212388816U discloses a curtain wall closed beam connection structure. The patent adopts a closed beam with a closed-loop cross-section. Since the cross-section of the open beam has an opening and is a non-closed-loop structure, the closed beam has a higher structural strength than the open beam. Under the condition of equal strength, the cross-sectional area of ​​the closed beam is smaller, which can reduce the mass of the aluminum profile and reduce the construction cost. Due to the high structural strength of the closed beam, compared with the open beam, the closed beam is not easy to twist, which improves the sensory effect. In addition, the beam insert is installed in the closed beam, and the spring pin is installed in the closed beam and the column, so that the connection between the closed beam and the column no longer requires aluminum alloy angle code and stainless steel bolts, and the beam insert and spring pin are also hidden in The closed crossbeam or column improves the visual effect, and at the same time avoids the traditional crossbeam and crossbeam buckle cover full-length joints, further improving the visual effect; the patent with the patent publication number CN213087162U discloses a closed crossbeam and column connection structure for frame curtain wall. The patent fixes the connection hanging code on the aluminum alloy column with screws, inserts the connection hanging code into the inner wall of the front end of the closed crossbeam, so that the closed crossbeam cannot rotate up and down, and then arranges a spring latch at the rear of the closed crossbeam, so that the closed crossbeam is firmly connected under the joint action of the connection hanging code and the spring latch. Through the joint arrangement of the connection hanging code and the spring latch, it not only avoids the phenomenon of the closed crossbeam appearing to fall after the hollow glass is installed, but also enhances the connection firmness of the closed crossbeam and the aluminum alloy column. The utility model is simple to install, solves the inevitable phenomenon of beam falling in conventional pure pin connection, sleeve core connection, angle aluminum connection and other methods, and improves the construction and installation quality.

[0004] Although the above patent can solve the problem of unsightly appearance, there is still a disadvantage: when the glass is installed on the column, gaps will appear between adjacent glasses.

DETAILED DESCRIPTION

[0022] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] Embodiment 1, this embodiment aims to provide a super-large panel glass curtain wall beam connection structure and construction method, which is mainly used for when the glass assembly is installed on the column 1, it can reduce the distance between adjacent glass assemblies, so that the glass assembly is more beautiful after installation. At present, when the glass assembly is installed on the column 1, the gap between adjacent glass assemblies is too large, which leads to poor appearance after filling with sealant or foam strips. In this embodiment, the glass assembly can be assembled on the U-shaped frame 601, and then the U-shaped frame 601 and the glass assembly are clamped through the mutual cooperation of the connecting assembly 4 and the installing assembly 6, so as to realize the situation of covering the gap after the glass assembly is installed, which greatly improves the aesthetics.

[0024] Based on the above problems, Figure 6 As shown, the crossbeam 2 can be mounted on the column 1 , so that the glass assembly can be mounted on the crossbeam 2 .

[0025] Specifically, a C-type core 8 is provided on the outer side of the column 1, and the C-type core 8 is fixed with a crossbeam 2; the C-type core 8 is used to be installed on the column 1 through a first stud 13, and the front and rear sides of the C-type core 8 are connected to the crossbeam 2 through a second screw 14. In this embodiment, the design of the C-type core 8 can enable the crossbeam 2 to be better connected to the column 1 to improve the connection stability.

[0026] The C-type insert 8 includes a vertical plate 801 and a horizontal plate 802 fixed on the front and rear sides of the vertical plate 801; the first stud 13 is used to fix the vertical plate 801 on the column 1. In this embodiment, three first studs 13 are used to fix the vertical plate 801 on the column 1. Through the three-point setting of the three first studs 13, a more stable connection can be achieved.

[0027] The second screw 14 is used to fix the cross plate 802 on the column 1; the front side of the cross beam 2 is inserted into the C-type core 8, facing the indoors, and the rear side of the cross beam 2 is inserted into the lower side of the C-type core 8, facing the outdoors. The cross beam 2 and the C-type core 8 are alternately plugged in, which facilitates the installation of the first stud 13.

[0028] The first stud 13 passes through the column 1 and the adjacent vertical plate 801 , and both ends of the first stud 13 are threadedly mounted with second nuts 15 .

[0029] A protective plate 16 is fixedly provided on the side of the beam 2 facing the room to protect the C-type core 8 and the beam 2. In this embodiment, the provision of the protective plate 16 enables the beam 2 to be installed on the C-type core 8, and the protective plate 16 can protect and cover the beam 2, which can not only achieve an aesthetic effect, but also protect the beam 2 from damage.

[0030] like Figure 1-3 As shown, by connecting the glass assembly to the column 1 , the glass assembly can be more stable.

[0031] Specifically, a cavity 5 is provided in the column 1 , the glass assembly is provided at the rear side of the column 1 , and a through hole is provided on a side of the column 1 facing the glass assembly, and the through hole is communicated with the cavity 5 .

[0032] The connecting assembly 4 includes a worm wheel 401, a worm 402 and a plug-in limit rod 403. In the present embodiment, the plug-in limit rod 403 consists of two parts, one of which is a threaded section and the other is a spline section. The spline section can be inserted into the spline limit tube 7 to drive the spline limit tube 7 to rotate, and the plug-in limit rod 403 passes through the vertical plate 801 and is threadedly connected with the first nut 11, and the threaded section can be connected with the first nut 11.

[0033] like Figure 5 As shown, the worm wheel 401 is rotatably arranged on the inner wall of the cavity 5, and the worm wheel 401 is meshed with the worm 402. In this embodiment, a connecting sleeve is fixedly arranged on the front side of the worm wheel 401, and the connecting sleeve is rotatably arranged on the inner wall of the cavity 5. A driving member is fixedly arranged on the inner wall of the worm wheel 401. Through the arrangement of the driving member, after the screw 603 is inserted, the rotation of the worm wheel 401 can drive the screw 603 to rotate; the installation component 6 includes a U-shaped frame 601 with an opening facing upward, a limiting disc 602 and a screw 603. Two adjacent glass components are fixedly connected to the same U-shaped frame 601. The limiting disc 602 is arranged in the U-shaped frame 601.

When the screw 603 is inserted into the worm gear 401, the construction personnel manually rotate the plug-in limit rod 403, so that the spline limit cylinder 7 can be driven to rotate. When the spline limit cylinder 7 rotates, the worm 402 can be driven to rotate. Since the worm wheel 401 is meshed with the worm 402, the worm wheel 401 can be driven to rotate. Since the screw 603 is inserted into the worm wheel 401, the screw 603 can be driven to rotate, so that the screw 603 moves forward and backward along the worm wheel 401, so that the glass assembly is fixedly installed.

[0035] Specifically, a clamping assembly 17 is provided on the rear side of the crossbeam 2 , and the clamping assembly 17 and the crossbeam 2 cooperate with each other to clamp the glass assembly in the middle, so as to improve the connectivity between the glass assembly and the crossbeam 2 .

[0036] The clamping assembly 17 includes a clamping plate 1701 and a fifth stud 1702 . The fifth stud 1702 passes through the clamping plate 1701 and is threadedly connected to the crossbeam 2 , so that the tightness of the clamping plate 1701 can be adjusted by rotating the fifth stud 1702 , and the clamping plate 1701 can be clamped against two glass assemblies.

[0037] A sealant or a foam strip is provided between the clamping plate 1701 and the glass assembly so as to protect the glass assembly.

[0038] Embodiment 2: In the structure of Embodiment 1, the cross beam 2 and the C-type ferrule 8 are staggeredly plugged in, so that the stability can be improved. However, since the friction between the cross beam 2 and the C-type ferrule 8 is relatively small, the cross beam 2 and the C-type ferrule are prone to loosening.

[0039] Based on the above problems, this embodiment Figure 4 As shown, a plurality of spaced auxiliary short plug plates 9 are fixedly provided at both ends of the vertical plate 801, and a first gap 12 is left between adjacent auxiliary short plug plates 9, and a plurality of spaced short interlocking plates 10 are fixedly provided on the crossbeam 2; the short interlocking plates 10 are inserted in the first gap 12, and a through hole for the second bolt to pass through is opened on the short interlocking plates 10. By staggered and cross-arranged, the contact area at the connection between the crossbeam 2 and the C-type core 8 can be increased, thereby improving the strength of the bonding or mechanical connection.

[0040] Compared with the first embodiment, the advantage of the present embodiment is that the contact area at the connection between the cross beam 2 and the C-type ferrule 8 is increased, which can make the connection stronger and improve the connection stability between the cross beam 2 and the C-type ferrule 8.

[0041] The specific operation of a construction method of a super-large plate glass curtain wall beam connection structure is as follows: S1, install the crossbeam 2 on the column 1 through the C-type ferrule 8, and connect the crossbeam 2 to the column 1 through the C-type ferrule 8 to ensure the stability of the structure; S2, assembling frames around the glass 302, and fixing the U-shaped frame 601 on the frames of two adjacent glass 302, and then placing the limiting disc 602 in the U-shaped frame 601, assembling the frames of the glass 302, and fixing the U-shaped frame 601 on the adjacent glass frames, and pre-placing the limiting disc 602 in the U-shaped frame 601 to prepare for the subsequent insertion of the screw 603; S3, assembling the C-type ferrule 8 on the column 1, and then connecting the crossbeam 2 with the C-type ferrule 8. The C-type ferrule 8 is pre-installed on the column 1 to ensure that the crossbeam 2 can be quickly and accurately connected with it; S4, insert the screw 603 into the cavity 5 through the through hole, then rotate the screw 603 so that the screw 603 is threadedly inserted into the worm gear 401, and the screw 603 passes through the through hole into the cavity 5 and is threadedly connected with the worm gear 401; S5, insert the plug-in limit rod 403 into the spline limit tube 7, and then rotate the plug-in limit rod 403 to drive the worm 402 to rotate. The worm 402 and the worm wheel 401 are meshed with each other, so the worm wheel 401 can be driven to rotate. When the worm wheel 401 rotates, the screw 603 drives the glass assembly to move, so that the glass assembly is installed on the column 1. Insert the plug-in limit rod 403 into the spline limit tube 7 and rotate it to drive the worm 402. The worm 402 is meshed with the worm wheel 401, driving the worm wheel 401 to rotate, and then the glass assembly is moved to the column 1 through the screw 603; S6, the plug-in limit rod 403 is threadedly connected with the first nut 11 to lock the plug-in limit rod 403. The plug-in limit rod 403 is threadedly connected with the first nut 11 to ensure that the plug-in limit rod 403 is firmly locked to avoid accidental movement; S7, the fifth stud 1702 passes through the clamping plate 1701 and is threadedly connected to the crossbeam 2, so that the tightness of the clamping plate 1701 can be adjusted by rotating the fifth stud 1702, and the clamping plate 1701 can be clamped against the two glass components.

[0042] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. The basic concept of the present invention is to insert the screw 603 into the worm wheel 401, and then drive the worm 402 to rotate by inserting the limit rod 403, so that the worm wheel 401 can be driven to rotate, so as to move the glass assembly to the column 1 through the screw 603, improve the installation effect of the glass assembly and the column 1, and also reduce the gap between adjacent glass assemblies to improve the aesthetics.
