Description

Technical Field

[0001] The invention relates to the field of building curtain walls, and in particular to a unit structure adapting to the angle change of a free-form surface and an installation method thereof. Background Art

[0002] With the continuous improvement of architectural design, processing and installation technology, the appearance of buildings has become more and more free and special. In order to adapt to the development trend of building skin, unit panels have continuously evolved into various forms to meet this demand. Among them, the adaptability of unit curtain walls to free-form surfaces is a typical problem, and there are often three ways to adapt to this problem:

[0003] a. For free skin, the use of hyperbolic curved panels can achieve a better appearance match. By making the glass and beams into curved shapes to adapt to the changes in the curved surface, the interference problem between the beams, columns and glass caused by the angle can be perfectly solved.

[0004] b. For free-form surfaces, another adaptation method is to keep the flat plate in a unit and adapt to the surface changes through a large number of molds at different angles. This method is also highly adaptable to the surface, and the number of molds often represents the matching accuracy of the appearance.

[0005] c. The third method is to add cold bending measures on the basis of the second method to reduce the number of molds to be opened. This method can reduce a certain number of molds by putting the units in place through cold bending measures on site or in the factory.

[0006] The prior art has the following problems:

[0007] 1. The first type of hyperbolic curved plate has a very high cost, which is unaffordable for most projects. The profile needs to be deformed to different curve shapes according to different units, even including twisting. All glass is also produced in special shapes.

[0008] 2. The second type is to open a large number of molds (molds of different angles) to adapt to the curved surface, usually about a set of molds every 1.5 to 2.5 degrees. This will lead to problems such as too many unit types, difficult processing, difficult installation and high costs.

[0009] 3. The third cold bending method means that long-term point loads need to be applied to the diagonal lines of the unit frame in the factory or on site. This long-term point load is extremely unfavorable to the stress of the structural adhesive and the nail line holes. The strength of the structural adhesive to withstand short-term loads is relatively large, but the strength to withstand long-term loads is about one twentieth of the short-term loads. In addition, when the unit frame is cold-bent, the weak point is at the screw connection position, and long-term loads are very likely to cause the screw position to slip and loosen. These will bring greater safety hazards to the project. Summary of the invention

[0010] (I) Purpose of the invention

[0011] In order to solve the technical problems existing in the background technology, the present invention proposes a unit structure that adapts to the angle change of the free-form surface, which has the characteristics of simultaneously solving the matching of the unit and the free-form surface, avoiding excessively high costs, and not leaving any safety hazards to the project.

[0012] (II) Technical solution

[0013] In order to solve the above technical problems, the present invention provides a unit structure that adapts to the angle change of the free-form surface. The column mold includes a first column and a second column that cooperate with each other. The convex section of the first column penetrates the concave end of the second column, and the angle between the two is adjusted through a rotating part:

[0014] A cushion frame is installed at the bottom of the first column and the second column, and a distance-adjusting portion for adjusting the distance is formed on the end surfaces of the two cushion frames that are close to each other;

[0015] The side walls of the first column and the second column are both provided with bottom cross beams, the outside of the bottom cross beams is provided with plug-in cross beams, and a limiting piece is provided between the bottom cross beam and the plug-in cross beam, and the two move synchronously.

[0016] Preferably, the distance adjusting portion comprises two hook rings, the two hook rings are nested, and the other ends are respectively connected to the two outer walls.

[0017] Preferably, the rotating part is movably mounted on the concave end of the second column, and the rotating part rotates synchronously with the convex section of the first column.

[0018] Preferably, the horizontal surfaces of the first column and the second column are provided with locking pieces, the locking pieces include a locking nail seat arranged on the inner wall of the first column, a spherical spherical gasket is arranged in the locking bolt ring seat, and a locking nail that passes through the horizontal surfaces of the first column and the second column is screwed between the locking nail seat and the spherical gasket.

[0019] Preferably, a cross beam pad is provided at one end of the bottom cross beam close to the pad frame, and a bolt connecting the two passes through the cross beam pad.

[0020] Preferably, the gaps between the first column, the second column and the bottom cross beam are filled with closed-cell sponge and sealant.

[0021] Preferably, the first column is provided with a plurality of fulcrums, the minimum distance of the gap between the two upper fulcrums and the bottom cross beam is 0.5 mm, and the maximum distance of the gap between the two lower fulcrums and the bottom cross beam is 5 mm.

[0022] Preferably, the expansion angle of the first column and the second column is 130-180°, and the rotation center is the center point of the distance adjustment portion.

[0023] Preferably, a top crossbeam is provided at one end of the plug-in crossbeam away from the bottom crossbeam, the top crossbeam and the plug-in crossbeam are connected by bolts, and one side of the top crossbeam is connected to another group of the cushion frames.

[0024] The present invention also provides a unit structure adapting to the angle change of a free-form surface and an installation method thereof, comprising the following steps:

[0025] Step 1: Position the column. The corners of the original curved surface of the curtain wall glass are the original grid points 1, 2, 3 and 4. The normal M of point 5 on the original curved surface of the curtain wall glass can be obtained by projecting the midpoint 5 of the original grid point 1 to the original curved surface. The direction M is the direction of the column. The center plane of the column can be obtained by stretching the straight line 1 along the direction M. The positioning plane of the column is defined by the direction M and the center plane. The column section is inserted and the column installation position can be obtained by stretching the section along the straight line 1.

[0026] Step 2: Position the bottom crossbeam and the plug-in crossbeam to obtain the installation positions of the left and right columns. In the cross-sectional view, since the crossbeam has an angle relative to the column, the gap between the top crossbeam and the column changes at the inner corner point and the outer corner point of the column. According to the size of the column mold adaptation angle, the inner corner point or the outer corner point is used as the positioning point, and the left and right two positioning points are connected and inserted into the cross-section stretching to obtain the installation positions of the bottom crossbeam and the plug-in crossbeam;

[0027] Step 3: Position the top crossbeam. Use the original positioning point as the positioning point of the top crossbeam, and insert the section on the connecting line. Keep the upper and lower surfaces of the section in the horizontal plane to obtain the installation position of the top crossbeam.

[0028] The above technical solution of the present invention has the following beneficial technical effects:

[0029] 1. The unit structure consists of column molds and beam molds. The positioning method of the column and beam, whether it is horizontal angle adaptation or vertical angle adaptation, can be adjusted by adjusting the column or beam positioning. When installing the glass curtain wall, only a small number of prefabricated column molds and beam molds are needed to adapt to the angle changes of the free-form surface;

[0030] 2. The crossbeam mold is a separate structure. The bottom crossbeam and the plug-in crossbeam can adjust the horizontal bending angle to adapt to the change of the vertical section angle. At the same time, the top crossbeam is not restricted by the bottom crossbeam and the plug-in crossbeam, so it can be installed freely, with a simple structure and convenient processing;

[0031] 3. The pad frame setting of the columns and beams, combined with the external sealing rubber, can seal the gaps to ensure overall sealing and installation stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0040] like Figure 1-5 As shown, the present invention proposes a unit structure and an installation method thereof that adapts to the change of the angle of the free-form surface. The column mold includes a first column 1 and a second column 2 that cooperate with each other. The convex section of the first column 1 penetrates the concave end of the second column 2, and the angle between the two is adjusted by a rotating part 3 to adapt to the preliminary adjustment of the angle of the free-form surface in the cross-sectional direction:

[0041] The first column 1 and the second column 2 are provided with a cushion frame 4 at their bottoms, and the end surfaces of the two cushion frames 4 close to each other are provided with a distance-adjusting portion 5 for adjusting the distance between them;

[0042] The side walls of the first column 1 and the second column 2 are both provided with a bottom cross beam 7, and the outside of the bottom cross beam 7 is provided with an insert cross beam 8. A limiting member is provided between the bottom cross beam 7 and the insert cross beam 8, and the two move synchronously to adapt to the preliminary adjustment of the free-form surface angle in the vertical section direction.

[0043] It should be noted that:

[0044] 1. The distance adjusting part 5 includes two hooks, which are nested and the other ends are respectively connected to the two outer walls. When adjusting the distance between the column molds, the two hooks are expanded outward or closed inward to perform a preliminary adjustment of the distance between the two.

[0045] 2. The rotating part 3 is movably mounted on the concave end of the second column 2, and the rotating part 3 rotates synchronously with the convex section of the first column 1. The rotating part 3 can slide along the concave end of the second column 2, with the same spacing adjustment range as the spacing adjustment part 5. The first column 1 is adjusted inward or outward with the second column 2 through the rotating part 3 to meet the bending requirements of the curved surface of the glass curtain wall.

[0046] The first column 1 and the second column 2 can be rotated to adjust the horizontal angle of the column mold. The first column 1 and the second column 2 are deployed at an angle of 130 to 180 degrees, and the rotation center is the center point of the distance adjustment part 5.

[0047] It can be understood that when adjusting the angle of the column, the first column is translated through the distance adjustment part. When the column is translated, since the first column 1 is provided with several fulcrums, each fulcrum does not interfere with the cross beam. The minimum distance of the gap between the two upper fulcrums and the bottom cross beam 7 is 0.5mm. Since the two upper fulcrums are at the airtight line position, excessive relaxation should be avoided. The tightness requirement is higher than that of the two lower fulcrums. The gap between the bottom cross beam 7 is at most 5mm. The gap size should be coordinated with the elasticity of the rubber strip, and cooperate with closed-cell sponge and sealant to avoid insufficient airtightness or watertightness due to excessive relaxation of the plug-in position.

[0048] It should be added that for larger gaps, column molds with other angles can be added to limit the gap to an acceptable range.

[0049] A pad frame is set at the bottom of the column mold. When the column mold adapts to different angles, the thickness of the structural adhesive will change. The change in the thickness of the structural adhesive may cause insufficient width or excessive thickness. The stability of the glass groove gap can be maintained by adding a pad frame. At the same time, the pad frame support feet and column ribs are cut and adjusted to maintain the stability of the beam structural adhesive thickness and the stability of the interior appearance.

[0050] As an example of adjusting the beam angle: rotate the upper unit column around the positioning point, move the beam to maintain the gap between the beam and the column. This method of construction is relatively simple and easy to process. The reason for moving the beam is: the indoor side plug-in position is the airtight position of the unit. Maintaining the gap here can minimize the looseness or interference of the beam column, thereby ensuring airtightness.

[0051] A top crossbeam 9 is provided at one end of the plug-in crossbeam 8 away from the bottom crossbeam 7. The top crossbeam 9 and the plug-in crossbeam 8 are connected by bolts. One side of the top crossbeam 9 is connected to another group of pad frames 4. It can be understood that the crossbeam is improved into a separate structure coordinated with the bottom crossbeam 7 and the plug-in crossbeam 8. The top crossbeam 9 is no longer constrained by the position of the plug-in crossbeam 8, so the deviation between the curtain wall glass and the positioning point can be solved. When the bottom crossbeam 7 and the plug-in crossbeam 8 rotate, since the top crossbeam 9 is installed in another unit, a larger angle deviation is allowed between the upper and lower units, and the difference between the upper and lower units is ±10°.

[0052] In order to solve the stability problem caused by the distance and angle changes between the cross beam and the glass surface, a cross beam pad is provided at one end of the bottom cross beam 7 close to the pad frame 4, and a bolt connecting the two passes through the cross beam pad.

[0053] In order to improve the sealing performance after the structures are combined, the gaps between the first column 1 and the second column 2 and the bottom cross beam 7 are filled with closed-cell sponge and sealant.

[0054] When the crossbeam is installed, the rotation angle of the crossbeam relative to the column also brings about the problem of nail line deviation, causing the locking nail 63 to protrude from the platform or interfere with the column wall. A spherical gasket 62 can be used to adapt to angle changes and position changes. The horizontal planes of the first column 1 and the second column 2 are provided with locking pieces, and the locking pieces include a locking nail seat 61 arranged on the inner wall of the first column 1, a spherical spherical gasket 62 is arranged in the lock bolt ring seat, and a locking nail 63 that passes through the horizontal planes of the first column 1 and the second column 2 is screwed between the locking nail seat 61 and the spherical gasket 62; the spherical gasket 62 with a spherical structure can be screwed into the locking nail 62 at any angle to ensure that the protruding position of the locking nail 63 is constant.

[0055] like Figure 3-5 As shown, a unit structure adapting to the angle change of a free-form surface and an installation method thereof include the following steps:

[0056] Step 1: Position the column. The corners of the original curved surface of the curtain wall glass are the original grid points 1, 2, 3 and 4. The normal M of point 5 on the original curved surface of the curtain wall glass can be obtained by projecting the midpoint 5 of the original grid point 1 to the original curved surface. The direction M is the direction of the column. The center plane of the column can be obtained by stretching the straight line 1 along the direction M. The positioning plane of the column is defined by the direction M and the center plane. The column section is inserted and the column installation position can be obtained by stretching the section along the straight line 1.

[0057] Step 2: Position the bottom crossbeam and the plug-in crossbeam to obtain the installation positions of the left and right columns. In the cross-sectional view, since the crossbeam has an angle relative to the column, the gap between the top crossbeam and the column changes at the inner corner point and the outer corner point of the column. According to the size of the column mold adaptation angle, the inner corner point or the outer corner point is used as the positioning point, and the left and right two positioning points are connected and inserted into the cross-section stretching to obtain the installation positions of the bottom crossbeam and the plug-in crossbeam;

[0058] Step 3: Position the top crossbeam. Use the original positioning point as the positioning point of the top crossbeam, and insert the section on the connecting line. Keep the upper and lower surfaces of the section in the horizontal plane to obtain the installation position of the top crossbeam.

[0059] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
