Technical Field

[0001] The utility model belongs to the technical field of glass curtain wall installation fittings, relates to a profile frame, and particularly relates to an aluminum alloy frame for a glass curtain wall. Background Art

[0002] At present, the installation methods of profile frames for bearing glass curtain walls in China或多或少存在着不太完美的方面。比如:1、开腔横梁,由于其具有开腔,所述横梁与竖梁连接配件都可以在开腔口处进行安装操作,虽然安装十分方便,但开腔型材特性导致该横梁在力学性能上表现较差,承受玻璃重力产生的扭矩的性能较差。2、闭腔横梁,其大致呈封闭的回字形结构,由于没有开腔,所以其结构受力较好,但是也因为没有开腔所以导致施工难度大,横梁与竖梁不好连接,横梁与角片连接处螺钉无法隐藏,装饰效果较差。所以如何提供一种结构受力好且安装方便的型材框架是我们当下刻不容缓要解决的问题。 Summary of the Utility Model

[0003] Aiming at the existing technical deficiencies, the utility model provides an aluminum alloy frame for a glass curtain wall. The technical problem it solves is how to balance the load-bearing strength and installation convenience of the profile frame.

[0004] In order to achieve the above object, the technical solution adopted by the utility model is:

[0005] An aluminum alloy frame for a glass curtain wall, comprising an aluminum alloy cross beam and two aluminum alloy vertical beams. The aluminum alloy cross beam is located between the aluminum alloy vertical beams. The cross sections of the aluminum alloy cross beam and the aluminum alloy vertical beams are both in a closed-loop structure. It is characterized in that positioning holes are provided on the opposite side parts of the two aluminum alloy vertical beams. Both ends of the aluminum alloy cross beam are connected with positioning cores. The positioning cores are provided with pin parts that can be inserted and pulled out in cooperation with the positioning holes. The pin parts can move relative to the aluminum alloy cross beam. When the end of the aluminum alloy cross beam is aligned with the positioning hole, the pin parts can be inserted into the positioning hole through movement.

[0006] It should be noted that there are some unclear expressions in the original text such as "或多或少存在着不太完美的方面" which have been translated as accurately as possible while maintaining the overall meaning. You may need to further clarify or correct the original text for a more precise translation.The aluminum alloy crossbeam and aluminum alloy vertical beam of the present application are both closed-cavity aluminum alloy profiles. The load-bearing capacity of such materials is better than that of open-cavity aluminum alloy profiles. The structural strength can be guaranteed after being assembled into an aluminum alloy frame. On this basis, the present application improves the connection structure of the aluminum alloy crossbeam and the aluminum alloy vertical beam, opens a positioning hole on the side of the aluminum alloy vertical beam, and arranges a movable pin portion on the end of the aluminum alloy crossbeam. Before installation, the pin portion is moved and immersed in the positioning core or in the aluminum alloy crossbeam. In this way, the aluminum alloy crossbeam does not have any protrusion in the length direction, and the aluminum alloy crossbeam can be pushed in between the two aluminum alloy vertical beams with just the right length. When the end of the aluminum alloy crossbeam is aligned with the positioning hole, the pin portion is moved and inserted into the positioning hole to complete the locking and fixation between the aluminum alloy crossbeam and the aluminum alloy vertical beam. Such a design is very convenient for assembling the aluminum alloy frame while taking into account the structural strength of the aluminum alloy frame.

[0007] In the above-mentioned glass curtain wall aluminum alloy frame, the positioning core is located on the inner side of the end of the aluminum alloy beam, the positioning core is adapted to the inner cavity of the aluminum alloy beam and can slide along the length direction of the aluminum alloy beam, and the pin portion is located on the outer side of the positioning core and can extend to the outside of the end of the aluminum alloy beam or sink into the inner cavity of the aluminum alloy beam through the sliding of the positioning core.

[0008] The positioning core of the present application is slidably arranged on the inner side of the inner cavity of the aluminum alloy beam, and the pin portion moves relative to the aluminum alloy beam through the sliding of the positioning core. At the beginning of installation, the pin portion is completely located in the aluminum alloy beam through the movement of the positioning core, and the aluminum alloy beam can be smoothly pushed between the two aluminum alloy beams. Then, the positioning core is moved to insert the pin portion into the positioning hole. This design is very convenient for installation while taking into account the structural strength.

[0009] In the above-mentioned aluminum alloy frame for a glass curtain wall, the positioning core is fixed at the end of the aluminum alloy beam, the pin portion can be extended and retracted relative to the positioning core, an elastic member that can keep the pin portion in an extended state is installed in the positioning core, the pin portion can be retracted into the positioning core by an external force, and when the pin portion is aligned with the positioning hole, the pin portion can be extended and inserted into the positioning hole under the action of the elastic force of the elastic member.

[0010] This is another embodiment of the pin portion of the present application. In this embodiment, the positioning core and the aluminum alloy cross beam are in a fixed relationship, and the pin portion itself can move relative to the positioning core. During installation, the pin portion can be pushed first to overcome the elastic force of the elastic member and sink into the positioning core. When the aluminum alloy cross beam is pushed between two aluminum alloy vertical beams, the pin portion is still in the positioning core because it is pushed by the side of the aluminum alloy vertical beam. However, when the pin portion moves and aligns with the positioning hole, the pin portion will pop out and be inserted into the positioning hole under the elastic force of the elastic member. This design also takes into account structural strength and is also very convenient for installation.

[0011] In the above-mentioned aluminum alloy frame for a glass curtain wall, travel holes communicating with the inner cavity are provided on the outer surfaces at both ends of the aluminum alloy beam, and the travel holes are arranged along the length direction of the aluminum alloy beam. A convex portion is provided on the side of the positioning core, and the convex portion extends from the travel hole and is exposed to the outside. The positioning core is synchronously driven to slide by pushing the convex portion to move along the travel hole.

[0012] A travel hole is provided on the outer side surface of the aluminum alloy beam of the present application, and the convex portion on the positioning core is adapted to the travel hole and extends out from the travel hole, so as to allow a person to push and pull to control the position of the positioning core. This design is simple to operate and makes the installation of the aluminum alloy beam more convenient. At the same time, after the closed-cavity aluminum alloy beam is installed, the structural strength and stress-bearing strength of the overall aluminum alloy frame are greatly improved.

[0013] In the above-mentioned glass curtain wall aluminum alloy frame, the protrusion is a screw, the screw is threadedly connected to the positioning core, the diameter of the big head end of the screw is larger than the width of the travel hole, and the positioning core can be locked and fixed by turning the screw.

[0014] The convex portion of the present application is designed to be a screw, which is threadedly connected to the positioning core. Firstly, the connection is detachable and easy to install. Secondly, after the pin portion and the positioning hole are socket-fitted, the position of the positioning core can be locked by tightening the screw. After locking, the positioning core will not move, thereby ensuring the strength and stability of the overall structure.

[0015] In the above-mentioned glass curtain wall aluminum alloy frame, the travel hole includes a straight hole portion and a circular hole portion which are interconnected. The circular hole portion is close to the end of the aluminum alloy beam. The contour of the circular hole portion is adapted to the big head end of the screw and the diameter of the circular hole portion is smaller than the big head end of the screw.

[0016] The travel hole of the present application is divided into a long straight hole part and a circular round hole part in the length direction of the aluminum alloy beam. After the positioning core is pushed outward so that the pin part and the positioning hole are in socket fit, the big head end of the screw is in the round hole part. At this time, the screw is rotated and locked. The big head of the screw can cooperate with the round hole part to make the positioning core difficult to move in the length direction of the aluminum alloy beam, so that the strength and stability of the overall structure are guaranteed, and it is convenient to operate.

[0017] At the same time, when the screw moves to the round hole, it can be judged that the pin part is extended into place and fits well with the positioning hole, which allows the user to more intuitively judge whether it is installed in place, thereby improving the overall installation strength and convenience from the side.

[0018] In the above-mentioned glass curtain wall aluminum alloy frame, the positioning core has at least two rows of pins, and the pins are detachably connected to the positioning core.

[0019] The design of multiple rows of pins can further increase the connection strength between the aluminum alloy crossbeam and the aluminum alloy vertical beam, thereby improving the load-bearing strength. The pins and the positioning core can be disassembled and fixed, which is also very convenient for assembly between various components. At the same time, when the pins are deformed, they can be replaced at any time, which is very convenient to operate.

[0020] In the above-mentioned aluminum alloy frame for glass curtain wall, the pin part is a bolt, a bolt hole penetrating the positioning core is opened on the positioning core, and the bolt is inserted into the bolt hole from one side and passed out from the other side.

[0021] The pin part is a bolt, and a bolt hole is opened on the positioning core. The bolt can pass through one hole and extend from another hole. This design of the bolt can effectively enhance the structural strength of the positioning core itself, thereby making the positioning core bear better force.

[0022] In the above-mentioned glass curtain wall aluminum alloy frame, the pin portion is a cylindrical pin, the positioning core is a square ring structure, an annular limit platform protrudes from the inner side wall of the positioning core, and the cylindrical pin is inserted into the limit platform and is tightly fitted and fixed with the limit platform.

[0023] This is another implementation of the pin part. In this implementation, the pin part is a cylindrical pin. The cylindrical pin is tightly fitted and fixed with the limit platform on the positioning core. The cylindrical pin is aligned with the limit platform and knocked in with a tool. This connection method is very convenient.

[0024] In the above-mentioned aluminum alloy frame for a glass curtain wall, a plurality of spaced and mutually parallel retaining ribs protrude from the outer periphery of the positioning core.

[0025] The beneficial effects of the utility model are as follows: the positioning core of the present application is slidably arranged on the inner side of the inner cavity of the aluminum alloy beam, and the pin portion moves relative to the aluminum alloy beam through the sliding of the positioning core. At the beginning of installation, the pin portion is completely located in the aluminum alloy beam through the movement of the positioning core, and the aluminum alloy beam can be smoothly pushed between two aluminum alloy beams. Subsequently, the positioning core is moved to allow the pin portion to be inserted into the positioning hole. This design is very convenient for installation while taking into account the structural strength. BRIEF DESCRIPTION OF THE DRAWINGS

The aluminum alloy crossbeam 1 and aluminum alloy vertical beam 2 of the present application are both closed-cavity aluminum alloy profiles. The load-bearing capacity of such materials is better than that of open-cavity aluminum alloy profiles. The structural strength can be guaranteed after being assembled into an aluminum alloy frame. On this basis, the present application improves the connection structure of the aluminum alloy crossbeam 1 and the aluminum alloy vertical beam 2, and a positioning hole 21 is opened on the side of the aluminum alloy vertical beam 2, and a movable pin portion 31 is provided on the end of the aluminum alloy crossbeam 1. Before installation, the pin portion 31 is moved and immersed in the positioning core 3 or in the aluminum alloy crossbeam 1. In this way, the aluminum alloy crossbeam 1 does not have any protrusion in the length direction, and the aluminum alloy crossbeam 1 can be pushed between the two aluminum alloy vertical beams 2 with just the right length. When the end of the aluminum alloy crossbeam 1 is aligned with the positioning hole 21, the pin portion 31 is moved and inserted into the positioning hole 21 to complete the locking fixation between the aluminum alloy crossbeam 1 and the aluminum alloy vertical beam 2. Such a design not only takes into account the structural strength of the aluminum alloy frame, but also facilitates the assembly of the aluminum alloy frame.

[0033] Furthermore, the positioning core 3 is located inside the end of the aluminum alloy beam 1, the positioning core 3 is adapted to the inner cavity of the aluminum alloy beam 1 and can slide along the length direction of the aluminum alloy beam 1, and the pin portion 31 is located outside the positioning core 3 and can extend to the outside of the end of the aluminum alloy beam 1 or sink into the inner cavity of the aluminum alloy beam 1 through the sliding of the positioning core 3. The positioning core 3 of the present application is slidably arranged inside the inner cavity of the aluminum alloy beam 1, and the pin portion 31 moves relative to the aluminum alloy beam 1 through the sliding of the positioning core 3. At the beginning of installation, the pin portion 31 is completely located in the aluminum alloy beam 1 through the movement of the positioning core 3, and the aluminum alloy beam 1 can be smoothly pushed between two aluminum alloy beams 1, and then the positioning core 3 is moved to allow the pin portion 31 to be inserted into the positioning hole 21. This design is very convenient for installation while taking into account the structural strength.

[0034] Furthermore, the outer surfaces of both ends of the aluminum alloy cross beam 1 are provided with travel holes 11 connected to the inner cavity thereof, and the travel holes 11 are arranged along the length direction of the aluminum alloy cross beam 1. The lateral side of the positioning core 3 is provided with a convex portion 32, which extends from the travel hole 11 and is exposed to the outside, and the positioning core 3 is synchronously driven to slide by pushing the convex portion 32 to move along the travel hole 11. The outer surface of the aluminum alloy cross beam 1 of the present application is provided with a travel hole 11, and the convex portion 32 on the positioning core 3 is adapted to the travel hole 11 and extends from the travel hole 11, and is used for people to push and pull to control the position of the positioning core 3. This design is simple to operate, making the installation of the aluminum alloy cross beam 1 more convenient. At the same time, after the closed cavity aluminum alloy cross beam 1 is installed, the structural strength and force strength of the overall aluminum alloy frame are greatly improved.

[0035] Furthermore, the convex part 32 is a screw, which is threadedly connected to the positioning core 3. The diameter of the large head end of the screw is larger than the width of the travel hole 11, and the positioning core 3 can be locked and fixed by turning the screw. The convex part 32 of the present application is designed as a screw, which is threadedly connected to the positioning core 3. On the one hand, it is a detachable connection method, which is convenient for installation. On the other hand, after the pin part 31 and the positioning hole 21 are socket-fitted, the position of the positioning core 3 can be locked by tightening the screw. After locking, the positioning core 3 will not move, thereby ensuring the strength and stability of the overall structure.

[0036] Furthermore, the travel hole 11 includes a straight hole portion 111 and a round hole portion 112 that are interconnected. The round hole portion 112 is close to the end of the aluminum alloy beam 1. The contour of the round hole portion 112 is adapted to the large end of the screw and the diameter of the round hole portion 112 is smaller than the large end of the screw. The travel hole 11 of the present application is divided into a long straight hole portion 111 and a circular round hole portion 112 in the length direction of the aluminum alloy beam 1. After the positioning core 3 is pushed outward so that the pin portion 31 and the positioning hole 21 are in socket fit, the large end of the screw is in the round hole portion 112. At this time, the screw is rotated and locked. The large head of the screw can cooperate with the round hole portion 112 to make the positioning core 3 difficult to move in the length direction of the aluminum alloy beam 1, so that the strength and stability of the overall structure are guaranteed, and the operation is convenient. At the same time, when the screw moves to the circular hole 112, it can also be judged that the pin portion 31 is extended into place and fits well with the positioning hole 21, which allows the user to more intuitively judge whether it is installed in place, thereby improving the overall installation strength and convenience from the side.

[0037] Furthermore, the positioning core 3 has two rows of pins 31, the upper row has two pins 31, and the lower row has one pin 31, so that a triangular structure is formed, which has better stability and strength, and the pins 31 are detachably connected to the positioning core 3.

The cylindrical pin is aligned with the stopper 33 and knocked in with a tool. This connection method is very convenient.

[0039] Furthermore, a plurality of spaced and parallel blocking ribs 34 are protruded from the outer periphery of the positioning core 3. The blocking ribs 34 make the positioning core 3 contact the inner wall of the aluminum alloy cross beam 1 more smoothly and can enhance the strength of the positioning core 3 itself.

[0041] This is another implementation of the pin portion 31 of the present application. In this embodiment, other structures are basically the same as those in the first embodiment, except that: in this embodiment, the positioning core 3 is fixed to the end of the aluminum alloy beam, and the pin portion 31 can be extended and retracted relative to the positioning core 3. An elastic member that can keep the pin portion 31 in an extended state is installed in the positioning core 3. The pin portion 31 can be retracted into the positioning core 3 by an external force, and when the pin portion 31 is aligned with the positioning hole 21, the pin portion 31 can be extended and inserted into the positioning hole 21 under the action of the elastic force of the elastic member. There is a fixed relationship between the positioning core 3 and the aluminum alloy crossbeam 1, and the pin portion 31 itself can move relative to the positioning core 3. During installation, the pin portion 31 can be pushed first to overcome the elastic force of the elastic member and sink into the positioning core 3. When the aluminum alloy crossbeam 1 is pushed between the two aluminum alloy vertical beams 2, the pin portion 31 is pushed by the side of the aluminum alloy vertical beam 2 and is still in the positioning core 3. However, when the pin portion 31 moves and aligns with the positioning hole 21, the pin portion 31 will pop out and be inserted into the positioning hole 21 under the action of the elastic force of the elastic member. This design also takes into account the structural strength and is also very convenient for installation.
