Description

Technical Field

[0001] The utility model belongs to the technical field of building engineering, and in particular relates to a one-way plate hinge node. Background Art

[0002] As an efficient structural component, cables in buildings have a wide range of applications: such as elevated roofs, squares and fences, tents and balcony supports, etc. Especially in large-span buildings, cables have unique structural forms, including bridge cables, angled bridge cables and suspension cable structures, which can be used for large-span roofs, large cantilevered awnings, etc.

[0003] Cables, an innovative structural form with many applications, have been continuously innovated in recent years, and there have been great advances in cable structure design and construction technology.

[0004] In cable structures, the cable + beam system that bears vertical loads plays a very important role. It is often used in bending members with large spans or large cantilevers, such as cantilever beams. Since cables have high strength, they are widely used in the structures of large buildings.

[0005] Since the cable is a flexible component, it can only bear tension but not pressure. Therefore, in the cable + beam system, under the action of gravity load, the cable bears the tension, which can effectively reduce the stress and deformation of the beam below; when an upward load occurs, such as wind suction, the cable will stop working and the load will be completely borne by the beam.

[0006] In this type of cable + beam system, the root of the beam is often treated as a hinge, so as to maximize the strength of the cable; however, this treatment method has a defect: that is, there is a lack of research on the performance of this type of structure under the action of reverse loads such as wind suction.

[0007] Existing technologies:

[0008] 1. In the cable + beam system, the beam end is treated as a hinge, that is, the beam end has the ability to rotate and deform.

[0009] 2. In the cable + beam system, the beam ends are treated as rigid connections, that is, the beam ends do not have the ability to rotate and deform.

[0010] Shortcomings of current technology:

[0011] 1. When the beam end of the cable + beam system is hinged, under the action of reverse loads such as wind suction, the cable will stop working due to pressure, and the load will be completely borne by the beam. Since the beam end is hinged, the beam will produce large internal forces and deformation, especially in cantilever beams. Since the beam end is hinged, the deformation of the beam under wind suction will be difficult to control;

[0012] 2. When the beam ends in the cable + beam system are treated as rigid connections, under the action of gravity load, the tension allocated to the cables is limited due to the large bending stiffness of the rigidly connected beams, and the cables are unable to exert their material strength advantages.

[0013] In view of the above problems, it is necessary to improve them. Utility Model Content

[0014] The utility model aims to provide a one-way plate hinge node with a simple structure and ingenious design.

[0017] As a preferred solution of the utility model, the width of the connecting plate is greater than the width of the beam.

[0018] As a preferred solution of the utility model, the buried plate assembly includes an upper buried plate and a lower buried plate; the upper and lower ends of the connecting plate are fixedly connected to the upper buried plate and the lower buried plate respectively.

[0019] As a preferred solution of the utility model, a gap is left between the bottom of the beam and the bottom of the connecting plate, and the gap is a welding space.

[0020] As a preferred solution of the utility model, the top of the beam is located in the middle or below the middle of the connecting plate.

[0021] As a preferred solution of the utility model, the top of the connecting plate is located in the middle or below the middle of the upper buried plate.

[0034] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Example:

[0037] like Figure 1-2 As shown, Figure 1 It is a side view of the one-way plate hinge node of the utility model; Figure 2 This is the front view of the one-way plate hinge node of the utility model.

[0038] A one-way plate hinge node includes a beam 1, a connecting plate 2 and an embedded plate assembly 3 fixed on a wall 10; the beam 1 is fixed on the connecting plate 2, and the connecting plate 2 is fixed on the embedded plate assembly 3; the utility model has a simple structure, and by arranging the beam, the connecting plate and the embedded plate assembly; under gravity load, the mechanical characteristics of the hinge are met.

[0039] The utility model is cleverly designed, and meets the mechanical characteristics of rigid connection under suction load by arranging beams, connecting plates and embedded plate components.

[0040] Specifically, the connecting plate 2 is a connecting plate with a narrow and long structure, and the beam 1 is fixed under the connecting plate 2 by welding or bolting. The connecting plate 2 is a connecting plate with a narrow and long structure, wherein the width of the embedded plate assembly 3 is greater than the width of the connecting plate 2. In this way, when the embedded plate assembly 3 is connected to the connecting plate 2, the connecting plate 2 can be completely attached to the embedded plate assembly 3, thereby increasing the force-bearing area of ​​the connecting plate 2 and ensuring safety of use.

[0041] In this embodiment, a cable 5 is installed between the beam 1 and the wall 10; since the cable 5 is a flexible component, it can only bear tension but not pressure; therefore, in this embodiment, the two ends of the cable 5 are respectively connected to the beam 1 and the wall 10. Under the action of gravity load, the cable 5 bears tension, which can effectively reduce the stress and deformation of the beam 1 below; when an upward load occurs, such as wind suction, the cable 5 will stop working, and the load will be completely borne by the beam 1.

[0042] The width of the connecting plate 2 is greater than the width of the beam 1; thus, when the connecting plate 2 is connected to the beam 1, the beam 1 can be completely attached to the connecting plate 2, thereby increasing the force-bearing area of ​​the beam 1 and ensuring safety in use.

[0043] like Figure 2 As shown, the buried plate assembly 3 includes an upper buried plate 30 and a lower buried plate 31; the upper and lower ends of the connecting plate 2 are fixedly connected to the upper buried plate 30 and the lower buried plate 31 respectively; specifically, the upper and lower ends of the connecting plate 2 are fixed to the upper buried plate 30 and the lower buried plate 31 by welding.

[0044] A gap 4 is left between the bottom of the beam 1 and the bottom of the connecting plate 2, and the gap 4 is a welding space; the gap 4 between the beam 1 and the connecting plate 2 is used to achieve alignment, ensure the accuracy of welding between the beam 1 and the connecting plate 2, and improve the processing quality and efficiency of the one-way plate hinge node.

[0045] The top of the beam 1 is located at the middle or below the middle of the connecting plate 2 ; the top of the connecting plate 2 is located at the middle or below the middle of the upper buried plate 30 .

[0046] The bottom of the connecting plate 2 is located in the middle or above the middle of the buried plate 31 ; the height of the beam 1 is 1 / 2 to 1 / 3 of the height of the connecting plate 2 . In this embodiment, the height of the beam 1 is 1 / 2 of the height of the connecting plate 2 .

[0047] like Figure 3 As shown, Figure 3 The schematic diagram of the hinge formed at the end of the beam under the positive bending moment of the utility model; when the cable + beam system bears the gravity load, the upper edge of the beam end is tensile and the lower edge is compressed; since the bending rigidity of the connecting plate 2 in the thickness direction is poor, the tension on the upper edge of the beam end drives the connecting plate 2 to bend and deform in the mid-span, forming bending deformation capacity, thereby meeting the requirements of the beam end hinge in the project.

[0048] like Figure 4 As shown, Figure 4 The schematic diagram of the utility model showing that the beam end is rigidly connected under reverse bending moment; when the cable + beam system bears the wind suction load, the lower edge of the beam end is pulled and the upper edge is compressed; due to the restraining effect of the buried plate 31, the lower edge of the beam end will not deform; after the beam end is compressed, it is supported by the connecting surface and will not deform; thus, the requirements for rigid connection of the beam end in the project are met.

[0049] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.

[0050] Although the following terms are used more frequently in this article: 1, beam; 2, connecting plate; 3, embedded plate assembly; 4, gap; 5, cable; 30, upper embedded plate; 31, lower embedded plate, etc., the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
