Description

Technical Field

[0001] The invention belongs to the technical field of construction, and particularly relates to an easily leveled curtain wall keel. Background Art

[0002] Curtain wall purlins refer to curtain wall columns and beams. Aluminum alloy profiles are a common purlin material for building curtain walls. Due to the low elastic modulus of aluminum alloy and its tendency to deform, large cross-sectional dimensions are required in long-span curtain wall structures to meet the curtain wall's deflection requirements. This increases material costs and impacts the building's interior space. For long-span curtain wall structures, steel-aluminum composite curtain wall purlins are currently commonly used; that is, the inner layer is a steel tube, and the outer layer is an aluminum alloy decorative profile. The inner steel tube bears the curtain wall load, while the outer aluminum alloy decorative profile serves only a decorative purpose. Due to the high elastic modulus of steel, the cross-sectional dimensions of the purlin can be significantly reduced compared to aluminum alloy purlins. Furthermore, by encapsulating the aluminum alloy decorative profile, the steel-aluminum composite curtain wall purlins achieve the same aesthetic quality as conventional aluminum alloy columns and beams.

[0003] However, due to the low factory precision of steel pipes and the welding process generally used during steel pipe installation, the thermal stress of welding can cause certain bending and twisting deformation of the steel pipes; while aluminum alloy profiles have high factory precision and good straightness. This makes it difficult to match the steel pipes and aluminum alloy decorative profiles of steel-aluminum combined curtain walls during installation. The solution to the above problem in the existing technology is to reserve a certain gap between the steel pipe and the aluminum alloy decorative profile, and use plastic spacers of different thicknesses during construction and installation to accommodate the difference in the gap between the steel pipe and the aluminum alloy decorative profile. However, this solution still has the following defects:

[0004] The bending and twisting deformation of steel pipes are uncertain, resulting in differences in the gap between the steel pipes and aluminum alloy decorative profiles at different positions, necessitating the preparation of a series of plastic pads of different thicknesses to adapt, resulting in low on-site installation efficiency; in addition, in order to reduce the types of pads of different thicknesses at the construction site, the difference in pads of different thicknesses is generally 1 to 2 mm, which easily leads to the low flatness of the final installed decorative profiles. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide an easily leveled curtain wall keel, which has the characteristic of convenient leveling of decorative profiles, is conducive to improving the flatness of decorative profiles and improving on-site construction efficiency.

DETAILED DESCRIPTION

[0034] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the present invention. The embodiments described are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative work are within the scope of protection of the present invention.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0036] Example 1

[0037] See also Figure 1-Figure 7, this embodiment discloses an easily leveled curtain wall keel, including a column 1 and a cross beam 2; both the column 1 and the cross beam 2 include a bearing member and a decorative component, and the bearing member is used to bear the curtain wall load. The decorative components of the column 1 and the cross beam 2 both include several decorative profiles and at least one leveling component; several decorative profiles are snap-connected to each other and form an outer wrapping structure to wrap the bearing member. In this embodiment, the bearing member is a steel pipe structure, and the decorative profile is an aluminum alloy profile structure, forming a steel-aluminum combined curtain wall keel; of course, other materials can also be used, and this embodiment is not limited thereto.

[0038] See Figure 1-Figure 2 , in the column 1 of this embodiment, there are four decorative profiles, including one fixed profile, two adjustable profiles, and one first assembly profile 5. For the convenience of distinction and understanding, the fixed profile in the column 1 of this embodiment is called the column fixed profile 3, the adjustable profile in the column 1 is called the column adjustable profile 4, and the bearing member in the column 1 is called the column bearing member 6.

[0039] The column fixed profile 3 is fixedly connected to one side of the column bearing member 6. In this embodiment, the second screw 8 is used to complete the connection, and specifically, the self-tapping screw can be selected; the two column adjustable profiles 4 are respectively located on both sides where the column bearing member 6 cooperates with the cross beam 2, and one side of the two column adjustable profiles 4 is respectively snap-connected to both sides of the column fixed profile 3; both sides of the first assembly profile 5 are respectively snap-connected to the other sides of the two column adjustable profiles 4, thereby forming an outer wrapping structure to wrap the column bearing member 6. The first assembly profile 5 is in a shape similar to "凵", and the snap-connection joints between the first assembly profile 5 and the two column adjustable profiles 4 are both located on the side where the column bearing member 6 cooperates with the cross beam 2.

[0040] The snap-connection method of the four decorative profiles in this embodiment adopts the first snap structure 13, including a card slot and a card block. The card slot and the card block are respectively located on the side edges of two adjacent decorative profiles, as Figure 2 shown. The snap-connection method between two adjacent decorative profiles in this embodiment can also refer to other snap structures in the prior art.

[0041] In this embodiment, four decorative profiles are combined to form an outer wrapping structure to wrap the column bearing member 6, with a simple and reliable structure and good flexibility. In addition, the wind load forms a large bending moment on the column bearing member 6. Therefore, in engineering, the cross-sectional bending resistance performance is generally improved by increasing the size of the column bearing member 6 in the Y direction. In this embodiment, the decorative profile of the column 1 is divided into three sections (including the first section is the column fixed profile 3, the second section is the column adjustable profile 4, and the third section is the first assembly profile 5). It is only necessary to increase the length of the second column adjustable profile 4 and select a column bearing member 6 with a larger size in the Y direction to obtain a steel-aluminum combined column structure with better bending resistance performance.

[0042] Aluminum decorative profiles of different cross-sections are produced by different molds. The cost of manufacturing profile molds is expensive, and the larger the profile cross-section, the higher the mold manufacturing cost. In this embodiment, four decorative profiles are combined to wrap the column bearing member 6. At this time, only the length of the adjustable column profile 4 needs to be changed to obtain a series of products, which is very economical.

[0043] See also Figure 1 、 Figure 2 and Figure 5 In this embodiment, the leveling assembly includes an adjusting member 10 , a connecting piece 9 and an adjusting block 11 .

[0044] The adjusting member 10 is threadedly connected to the column adjustable profile 4, and one end of the adjusting member 10 is locked on the column support 6 to prevent it from falling out. The gap between the column adjustable profile 4 and the column support 6 can be adjusted by screwing the adjusting member 10. A connecting piece 9 is fixedly connected to the column support 6 and is provided with a retaining hole 19 to prevent the adjusting member 10 from falling out. A retaining step 20 is provided at one end of the adjusting member 10, which is set in the retaining hole 19, and the adjusting member 10 can rotate relative to the connecting piece 9. The connection piece 9 is provided to cooperate with the adjusting member 10 to achieve mutual abutment between the adjusting member 10 and the column support 6. Therefore, the straightness of the column adjustable profile 4 can be adjusted by screwing the adjusting member 10 and combining the function of the threaded structure.

[0045] Furthermore, the adjusting member 10 of this embodiment is a screw structure, the limiting step 20 is tapered, and the limiting hole 19 is also configured as a corresponding tapered structure; of course, the limiting step 20 and limiting hole 19 can also be configured as other structures, such as a stepped cone or a stepped countersunk hole structure, to achieve the same limiting function. To facilitate the rotation of the adjusting member 10, a slot is provided on the end of the adjusting member 10 away from the connecting piece 9.

[0046] Furthermore, the connecting piece 9 is fixedly connected to the column support member 6 via a first screw 7. Specifically, in this embodiment, self-tapping screws can be used to securely connect the connecting piece 9 to the column support member 6. This simplifies installation and allows for on-site operation. The position of the connecting piece 9 can be flexibly adjusted based on site conditions, improving installation accuracy and enabling adjustment of the straightness of the column adjustable profile 4. Alternatively, other methods can be used to securely connect the connecting piece 9 to the column support member 6, such as welding or bolt and nut fixing.

[0047] The adjustment block 11 is provided with a threaded hole 18. The column adjustable profile 4 is provided with a limiting groove 12 for accommodating and limiting the axial movement of the adjustment block 11 along the adjustment member 10. The adjustment block 11 is disposed in the limiting groove 12. A through hole is provided on one side of the limiting groove 12. The adjustment member 10 passes through the through hole and engages with the threaded hole 18 in the adjustment block 11, thereby achieving a threaded connection with the column adjustable profile 4. Specifically, in this embodiment, the limiting groove 12 is generally C-shaped. The threaded hole 18 in the adjustment block 11 cooperates with the adjustment member 10 to achieve a threaded connection between the adjustment member 10 and the column adjustable profile 4. This eliminates the need to manufacture additional threaded holes 18 in the column adjustable profile 4. Instead, the column adjustable profile 4 only needs to be manufactured uniformly with the limiting groove 12, simplifying the manufacturing difficulty of the decorative profile and reducing costs. In addition, the adjustment block 11 can slide in the limiting groove 12, allowing for more flexible and convenient engagement with the adjustment member 10, improving assembly convenience and flexibility.

[0048] Furthermore, since the connecting piece 9 of this embodiment can also be flexibly fixed at any position on the column support member 6 according to actual conditions, the entire leveling assembly of this embodiment can be flexibly installed according to on-site assembly conditions, thereby facilitating the selection of the optimal gap adjustment point for leveling the column adjustable profile 4. In this case, after determining the installation position of the leveling assembly, it is only necessary to drill through holes corresponding to the limit slots 12 of the column adjustable profile 4, which is very simple and convenient.

[0049] See also Figure 3-Figure 4 In this embodiment, the crossbeam 2 has three decorative profiles: a fixed profile, an adjustable profile, and a second assembly profile 16. For ease of distinction, in this embodiment, the fixed profile in crossbeam 2 is referred to as crossbeam fixed profile 14, the adjustable profile in crossbeam 2 is referred to as crossbeam adjustable profile 15, and the bearing member in crossbeam 2 is referred to as crossbeam bearing member 17. Both the adjustable crossbeam profile 15 and the second assembly profile 16 are similar to a "7" shape, with the snap connection between the adjustable crossbeam profile 15 and the second assembly profile 16 facing the fixed crossbeam profile 14.

[0050] See also Figure 4 Because crossbeam 2 of this embodiment includes three decorative profiles, the snap-fit ​​connection between adjustable crossbeam profile 15 and second assembly profile 16 differs from that of column 1. Specifically, a second snap-fit ​​structure 21 and a third snap-fit ​​structure 22 are provided between adjustable crossbeam profile 15 and the third assembly profile. These structures define different directions, thereby effectively connecting and securing adjustable crossbeam profile 15 and second assembly profile 16.

[0051] The assembly and adjustment method of the decorative profile of the crossbeam 2 of this embodiment can refer to the decorative profile structure of the column 1.

[0052] See also Figure 6The joint between the adjustable column profile 4 and the first assembly profile 5 is flush with the side of the beam fixing profile 14 or the adjustable beam profile 15. It can also be considered that the width of the adjustable column profile 4 matches the overall width of the beam 2 (including the decorative profile), so that during the assembly process, there is no need to process incisions on the adjustable column profile 4, simplifying the structure of the adjustable column profile 4. The end of the adjustable column profile 4 can be directly cut into a straight cut, that is, the end processing of the profile can be completed by directly cutting off the material during processing.

[0053] In addition, if Figure 7 As shown, the column bearing member 6 and the crossbeam bearing member 17 both have a certain length. Therefore, in order to improve the flatness of the column adjustable profile 4 and the crossbeam adjustable profile 15, multiple leveling components can be set on the column adjustable profile 4 and the crossbeam adjustable profile 15 to better adapt to the bearing members, and finally assemble to obtain an outer decorative profile with high flatness.

[0054] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
