[0008] According to the first aspect, in a possible implementation manner, on at least one of the trusses, the first mounting hole passed through by the fastener is located at the end, and the end of one of the trusses contacts the other truss so that the two connecting plates and the two trusses are connected in one-to-one correspondence to form an internal corner.

Detailed implementation manners

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

When a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component at the same time.

[0030] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in this application in the specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this application includes any and all combinations of one or more of the related listed items.

[0031] The following will describe in detail some embodiments of this application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0032] This application provides a climbing formwork. The climbing formwork includes a truss corner connection structure. The truss is fixed on each climbing unit, climbing frame and tower, which can effectively enhance the stability of the entire climbing formwork structure.

[0033] The climbing formwork also includes conventional necessary or unnecessary structures in the art such as a main frame, an attachment support, an anti-tilting device, a lifting mechanism, an anti-falling structure, an intelligent control system, etc. This application does not limit this.

[0034] Please refer to Figure 1 and Figure 2 , in an embodiment, the truss corner connection structure 100 includes a truss 10, a corner connector 20 and a fastener 30.

[0035] Two trusses 10 are perpendicular to each other to form a right-angle connection point in structure. Each truss 10 is designed with sufficient strength and stiffness to withstand the forces from the climbing formwork system and other external loads. Each truss 10 is provided with at least two rows of first mounting holes 11. A plurality of first mounting holes 11 in the same row are arranged along the length direction of the truss 10; this provides flexibility for its connection with the corner connector 20 and ensures a stable connection under different working conditions.

[0036] The corner connector 20 is a key component for connecting two perpendicular trusses 10. The corner connector 20 is composed of two perpendicularly connected connecting plates 21, and these two connecting plates 21 respectively correspond to the two trusses 10. Each connecting plate 21 is provided with two second mounting holes 22 spaced apart in the height direction, and the second mounting holes 22 are aligned with the first mounting holes 11 on the truss 10 in the height direction.

[0037] Fastener 30, the number of fasteners 30 (such as bolts, pins, etc.) is the same as the number of second mounting holes 22 on the corner connector 20. They pass through the corresponding second mounting holes 22 and any one of the first mounting holes 11 on the truss 10 (selected according to actual needs in the same row), thereby firmly connecting the corner connector 20 with the two trusses 10 together.

[0038] By adjusting the position of the fastener 30, for example, adjusting the fastener 30 to pass through different first mounting holes 11, the two trusses 10 can be in different connection positions to form a right-angle structure, thereby allowing the formation of an external corner or an internal corner between the two trusses 10, greatly enhancing the versatility and adaptability. And in this application, using one connector to achieve at least two connection points in the height direction can effectively disperse the stress borne at the connection. Compared with single-point connection, multi-point connection can avoid stress concentration and reduce the risk of connection failure caused by excessive local stress; multiple connection points connect the corner connector 20 and the truss 10 more tightly together, forming a more stable overall structure. This stability can also improve the connection strength, help resist external loads and vibrations, and improve the overall safety of the climbing formwork system.

[0039] Among them, use a fastener 30 (such as a bolt) to pass through the second mounting hole 22 on the corner connector 20 and screw it into the corresponding first mounting hole 11 of the truss 10. According to needs, washers or lock nuts may be used to increase the stability of the connection. That is, the first mounting hole 11 can be a threaded hole, and the fastener 30 passes through the second mounting hole 22 and is threadedly connected to the first mounting hole 11; the fastener 30 can also be threadedly connected to a nut after passing through the second mounting hole 22 and the first mounting hole 11 to lock the connecting plate 21 and the truss 10. This application does not make any limitations on this.

[0040] Among them, the corner connector 20 is an integrally formed structure by bending, and the manufacturing process is simpler. It reduces the number of parts and assembly steps, and reduces the production cost and complexity. In a multi-component assembly structure, the connection points between each component may become potential failure points. And the corner connector 20 adopting an integral structure reduces the number of these connection points, thereby reducing the probability of failure and making the climbing formwork system more reliable and durable.

[0041] Based on the above embodiments, the first mounting hole 11 is a round hole, and the second mounting hole 22 is a kidney-shaped hole. The long-strip design of the kidney-shaped hole allows the fastener 30 to move and adjust within a certain range in its length direction. This flexibility enables the connection position between the corner connector 20 and the truss 10 to be adjusted more precisely to meet different construction requirements.

[0042] Combining the round hole as the first mounting hole 11 with the waist-shaped hole as the second mounting hole 22 can give full play to the advantages of both. The precision and stability of the round hole ensure the accuracy and reliability of the connection; while the flexibility and error absorption capacity of the waist-shaped hole make the connection process smoother and more efficient. This combined design not only improves the overall performance of the truss corner connection structure 100, but also enhances the versatility and adaptability of the climbing frame system.

[0043] In the present application, the connection methods of the upper and lower fasteners 30, the connecting plate 21 and the truss 10 are the same, and the following description will be made in detail by taking one side as an example. Figure 3 , define the side of the angle formed between the two trusses 10 as the inner side, and the other side as the outer side. Define the thickness of the truss 10 as A, the distance between the first mounting hole 11 at the end and the edge of the truss 10 as B, and the distance between two adjacent first mounting holes 11 as C; the distance between the centers of the arc surfaces at both ends of the second mounting hole 22 is D, and the distance between the arc surface at one end and the right angle vertex formed by the two connecting plates 21 is E.

[0044] Among them, D+E>A+B, this condition ensures that when both connecting plates 21 are located on the outside of the truss 10, the fastener 30 can smoothly pass through the second mounting hole 22 (waist-shaped hole) and connect with the connecting plate 21, and will not interfere with the truss 10 itself. It ensures the feasibility of installing the connecting plate 21 on the outside of the truss 10; D<C, this condition limits the extension length of the second mounting hole 22 (waist-shaped hole) to avoid its excessive length causing unnecessary deformation or stress concentration of the connecting structure when subjected to force. At the same time, it also ensures that there is enough spacing between adjacent fasteners 30, thereby improving the stability of the connection; E≤B, when both connecting plates 21 are located on the inside of the truss 10, this condition ensures that the fastener 30 can be effectively connected to the connecting plate 21 after passing through the second mounting hole 22, without exceeding the edge of the truss 10. It increases the flexibility of the connecting structure when it is installed on the inside of the truss 10.

[0045] In other embodiments, D≥C, then two fasteners 30 may pass through the same second mounting hole 22 and pass through two adjacent first mounting holes 11 one by one, thereby ensuring the stability of the connection.

[0046] The following describes the situation where the two trusses 10 are in different connection positions:

[0047] The first mounting hole 11 through which the fastener 30 passes is located at the end, which is the basis for forming the external angle structure. At least one of the connecting plates 21 is fitted with the inner side of the corresponding truss 10, and the two connecting plates 21 and the two trusses 10 are connected one by one, so that part of the connecting plate 21 is exposed from the end gap of the two trusses 10, forming a clear external angle structure.

[0048] On at least one truss 10, the fastener 30 passes through the first mounting hole 11 at the end, and the end of one truss 10 contacts the other truss 10 in such a way that the two trusses 10 can support each other at the corner, thus forming an internal corner structure. This contact can be direct physical contact. The connecting plates 21 play the role of a bridge in the internal corner structure. They are respectively connected to the two trusses 10 and fixed by the fasteners 30. The presence of the connecting plates 21 makes the connection between the two trusses 10 more stable and can also transfer and disperse the forces from the trusses 10.

[0049] The fitting manner of the connecting plate 21 with the corresponding truss 10 can be the inner side or the outer side. Inner side fitting means that the connecting plate 21 is closely attached to the inner side surface of the truss 10. This way may be more suitable for occasions where it is necessary to hide the connecting plate 21 or reduce the structural size. Outer side fitting means that the connecting plate 21 is located on the outer side of the truss 10. This way may be more suitable for occasions where it is necessary to enhance the structural appearance or facilitate maintenance. The specific choice of fitting manner depends on the design requirements and construction conditions.

[0050] In the specific implementation, for the convenience of description, two trusses 10 are defined as the first truss 10a and the second truss 10b respectively, two connecting plates 21 are defined as the first connecting plate 21a and the second connecting plate 21b respectively, and one end of the second mounting hole 22 close to the right-angle vertex is the first end, and the other end is the second end.

[0051] In the first embodiment, as Figure 4 shown, the first connecting plate 21a is fitted to the inner side of the first truss 10a. A fastener 30 passes through the first end of the second mounting hole 22 on the first connecting plate 21a and the first mounting hole 11 at the end on the first truss 10a; the second connecting plate 21b is fitted to the outer side of the second truss 10b. Another fastener 30 passes through the second end of the second mounting hole 22 on the second connecting plate 21b and the first mounting hole 11 at the end on the second truss 10b, so that there is a gap between the end of the second truss 10b and the inner side of the first truss 10a, thereby forming an external corner structure.

[0052] In the second embodiment, as Figure 5 shown, the first connecting plate 21a is fitted to the inner side of the first truss 10a. A fastener 30 passes through the second end of the second mounting hole 22 on the first connecting plate 21a and any one of the first mounting holes 11 in the middle on the first truss 10a; the second connecting plate 21b is fitted to the inner side of the second truss 10b. Another fastener 30 passes through the second end of the second mounting hole 22 on the second connecting plate 21b and the first mounting hole 11 at the end on the second truss 10b, so that there is a gap between the end of the second truss 10b and the inner side of the first truss 10a, thereby forming an external corner structure.

[0053] In the third embodiment, as Figure 6 shown, the difference between the third embodiment and the second embodiment is that the fastener 30 passes through the second end of the second mounting hole 22 on the first connecting plate 21a and the first mounting hole 11 at the end of the first truss 10a, creating a certain gap at the apex angle of the two trusses 10 and the corner connector 20, thereby forming an external corner structure.

[0054] In the fourth embodiment, as Figure 7 shown, the first connecting plate 21a is attached to the inner side of the first truss 10a, and one fastener 30 passes through the first end of the second mounting hole 22 on the first connecting plate 21a and the first mounting hole 11 at the end of the first truss 10a; the second connecting plate 21b is attached to the inner side of the second truss 10b, and another fastener 30 passes through the first end of the second mounting hole 22 on the second connecting plate 21b and the first mounting hole 11 at the end of the second truss 10b, causing the end of the second truss 10b to contact the end of the first truss 10a, thereby forming an internal corner structure.

[0055] In the fifth embodiment, as Figure 8 shown, the first connecting plate 21a is attached to the outer side of the first truss 10a, and one fastener 30 passes through the second end of the second mounting hole 22 on the first connecting plate 21a and the first mounting hole 11 at the end of the first truss 10a; the second connecting plate 21b is attached to the outer side of the second truss 10b, and another fastener 30 passes through the second end of the second mounting hole 22 on the second connecting plate 21b and the first mounting hole 11 at the end of the second truss 10b, causing the end of the second truss 10b to contact the end of the first truss 10a, thereby forming an internal corner structure.

[0056] In the sixth embodiment, as Figure 9 shown, the first connecting plate 21a is attached to the inner side of the first truss 10a, and one fastener 30 passes through the second end of the second mounting hole 22 on the first connecting plate 21a and the first mounting hole 11 at the end of the first truss 10a; the second connecting plate 21b is attached to the outer side of the second truss 10b, and another fastener 30 passes through the first end of the second mounting hole 22 on the second connecting plate 21b and the first mounting hole 11 at the end of the second truss 10b, causing the end of the second truss 10b to fit against the inner side of the first truss 10a, thereby forming an internal corner structure.

[0057] In the seventh embodiment, as Figure 10As shown, the first connecting plate 21a is attached to the inner side of the first truss 10a. A fastener 30 passes through the second end of the second mounting hole 22 on the first connecting plate 21a and any one of the first mounting holes 11 in the middle on the first truss 10a. The second connecting plate 21b is attached to the inner side of the second truss 10b. Another fastener 30 passes through the first end of the second mounting hole 22 on the second connecting plate 21b and the first mounting hole 11 at the end on the second truss 10b, so that the end of the second truss 10b is attached to the inner side of the first truss 10a, thereby forming an internal corner structure.

[0058] It should be noted that in the above embodiments, the first truss 10a and the second truss 10b are only for convenient distinction and do not refer to the positional relationship. That is to say, the first truss 10a and the second truss 10b can be mutually replaced to achieve different connection methods. And due to the existence of processing errors and assembly errors, the fastener 30 is not completely located at the first end or the second end of the second mounting hole 22, and the first truss 10a and the second truss 10b are not completely attached.

[0059] In one embodiment, please refer here Figure 1 and Figure 2 , the projection of the connecting plate 21 on the truss 10 does not expose beyond the top and bottom of the truss 10. That is, the height dimension of the corner connector 20 is smaller than the height dimension of the truss 10, and neither the upper edge nor the lower edge of the connecting plate 21 exceeds the top and bottom edges of the truss 10. This makes the whole structure look neater and more unified, enhancing the integrity of the structure.

[0060] In one embodiment, the truss 10 includes a top beam 12, a bottom beam 13, and vertical beams 14 connecting the top beam 12 and the bottom beam 13. The vertical beams 14 connect the top beam 12 and the bottom beam 13 to form the main longitudinal support of the truss 10. They together with the top beam 12 and the bottom beam 13 constitute a basic rectangular or square frame, providing basic stability and stiffness for the whole structure. First mounting holes 11 are provided on both the top beam 12 and the bottom beam 13, and the number of the first mounting holes 11 on the top beam 12 is the same as that on the bottom beam 13 and they are arranged in alignment. One of the second mounting holes 22 is height-aligned with the first mounting hole 11 on the top beam 12, and the other second mounting hole 22 is height-aligned with the first mounting hole 11 on the bottom beam 13. That is, the connection points of the corner connector 20 with the truss 10 are arranged close to the top and the bottom. The arrangement of the corner connectors 20 close to the top and the bottom enables the whole structure to better resist deformation and damage when subjected to external loads, improving the overall performance and safety of the structure.

[0061] Furthermore, the truss 10 further includes a diagonal brace beam 15, which is connected to the diagonals of the rectangular frame formed by the top beam 12, the bottom beam 13, and the two longitudinal beams 14, providing additional supporting force. This diagonal bracing can effectively resist lateral and torsional forces, preventing the truss 10 from deforming or breaking under the action of these forces.

[0062] When there are more than two longitudinal beams 14, the truss 10 can form multiple adjacent rectangular frames. Each rectangular frame is jointly composed of the top beam 12, the bottom beam 13, and the longitudinal beams 14 on both sides, forming an independent support unit. For each rectangular frame, a diagonal brace beam 15 is correspondingly provided. These diagonal brace beams 15 are also connected to the diagonals of the rectangular frame to provide additional supporting force. The diagonal brace beams 15 of two adjacent rectangular frames can intersect to further enhance the stability and stiffness of the entire truss corner connection structure 100.

[0063] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0064] The above-disclosed is only a preferred embodiment of the present application. Of course, it cannot be used to limit the scope of the rights of the present application. Those of ordinary skill in the art can understand the whole or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
