Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a railing node. Background Technology

[0002] Currently, most common railing joints on the market use horizontal bars and straight sleeves on the base (such as...). Figure 5 ) or corner sleeve (such as Figure 4 The traditional connection method involves a self-tapping screw, typically driven into the straight or corner sleeve from bottom to top, to secure the crossbar inside. However, this method has significant drawbacks: firstly, limited installation space forces workers to work from below, making screw positioning difficult, installation inefficient, and unsafe; secondly, the self-tapping screw is completely exposed to rain and moisture, making it prone to corrosion, which reduces shear and tensile strength at the screw-sleeve connection. With increasing service life, corrosion-induced thread wear and loosening significantly weaken the joint structure, potentially leading to crossbar detachment and other safety hazards, severely impacting the overall stability and lifespan of the railing. Utility Model Content

[0003] The purpose of this utility model is to provide a railing node that solves the above-mentioned problems existing in the prior art.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] A railing node includes a base, an upper cover, a lower cover, and a protrusion. The base is fixedly connected to an external column. The lower cover is horizontally fixedly connected to the upper part of the base. The outer edge of the protrusion is horizontally fixedly connected to the inner wall of the lower cover. The outer edge and the middle part of the protrusion abut against the end face of the horizontal tube and are inserted into the inner wall of the horizontal tube, respectively. The upper cover and the lower cover are fastened together to cover the ends of the protrusion and the horizontal tube. A sealing ring surrounding the horizontal tube is provided at the joint of the ends of the lower cover and the upper cover.

[0006] The beneficial effects of this utility model are: by setting a protrusion to engage with the horizontal tube, and by fastening the lower cover to the upper cover, the installation is simple and the installation space is not restricted; the upper cover covers the ends of the protrusion and the horizontal tube inside the lower cover, and the sealing is achieved by the sealing ring, which makes it less prone to rust and does not affect the strength of the railing joint.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, several countersunk holes are provided on the top surface of the horizontal tube, and several threaded holes are provided on the protrusions corresponding to the countersunk holes.

[0009] The further beneficial effects of adopting the above are: the connection stability between the convex horizontal tubes is further enhanced by the threaded connection, and the screw nut can be directly screwed into the countersunk hole without hindering the snap-fit ​​between the upper cover and the lower cover.

[0010] Furthermore, the lower cover and the upper cover are respectively secured by the first and second J-shaped locking strips.

[0011] The further beneficial effects of the above are: when fastening, the top cover is struck with a hammer to tighten the first and second locking strips. After tightening, the gap between the top and bottom covers is extremely small, and the top and bottom covers are not easy to fall off. Attached Figure Description

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] Example 1

[0021] like Figure 1 and Figure 2As shown, a railing node includes a base 1, an upper cover 3, a lower cover 2, and a protrusion 4. The base 1 is fixedly connected to an external column. The lower cover 2 is horizontally fixedly connected to the upper part of the base 1. The outer edge of the protrusion 4 is horizontally fixedly connected to the inner wall of the lower cover 2. The outer edge and the middle part of the protrusion 4 abut against the end face of the horizontal tube 5, respectively, and are inserted into the inner wall of the horizontal tube 5. The upper cover 3 is fastened to the lower cover 2 to cover the ends of the protrusion 4 and the horizontal tube 5. The ends of the lower cover 2 and the upper cover 3 are joined together and a sealing ring 7 is provided around the horizontal tube 5.

[0022] When installing the railing node, first fix the base 1 on the external column, then insert the two horizontal tubes 5 into the two protrusions 4 respectively, and then fasten the upper cover 3. The installation is simple and the installation space is not restricted by setting the protrusions 4 and the horizontal tubes 5 to snap together, and the lower cover 2 and the upper cover 3 to snap together. The upper cover 3 covers the ends of the protrusions 4 and the horizontal tubes 5 inside the lower cover 2, and the sealing ring 7 is used to achieve a seal, which is not easy to rust and does not affect the strength of the railing node.

[0023] Example 2

[0024] like Figure 1 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0025] Several countersunk holes 51 are provided on the top surface of the horizontal tube 5, and several threaded holes 41 are provided on the protrusion 4 corresponding to the countersunk holes 51. The connection stability between the protrusion 4 and the horizontal tube 5 is further enhanced by the threaded connection, and the screw nut can be directly screwed into the countersunk hole 51 without hindering the connection between the upper cover 3 and the lower cover 2.

[0026] Example 3

[0027] like Figures 1 to 2 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0028] The lower cover 2 and the upper cover 3 are straight sections. Two protrusions 4 are arranged back-to-back along the extension direction of the upper cover 3 and the lower cover 2. A fastening structure 6, which is made of square steel, is provided between the two protrusions 4. The fastening structure 6 improves the structural strength of the railing joint.

[0029] The lower cover 2 and the upper cover 3 are corner sections. Two protrusions 4 are set perpendicularly to each other and back to back along the extension direction of the upper cover 3 and the lower cover 2. A fastening structure 6, which is a right-angle steel, is set between the two protrusions 4. The fastening structure 6 improves the structural strength of the railing joint.

[0030] The inner side of the right-angle steel is reinforced with ribs 61. This improves the structural strength of the right-angle steel, and consequently improves the structural strength of the railing joint at the corner.

[0031] Example 4

[0032] like Figures 1 to 3 As shown, this embodiment is a further improvement on embodiment 3, as detailed below:

[0033] The lower cover 2 and the upper cover 3 are respectively fastened by the first locking strip 21 and the second locking strip 31 in a J shape. When fastening, the upper cover 3 is struck with a hammer to tighten the first locking strip 21 and the second locking strip 31. After tightening, the gap between the upper cover 3 and the lower cover 2 is very small, and the upper cover 3 and the lower cover 2 are not easy to fall off.

[0034] The lower cover 2, upper cover 3, and horizontal tube 5 are all made of zinc-coated steel. Zinc-coated steel has a long service life, low maintenance costs, and strong rust resistance.

[0035] The protrusion 4 is made of cast iron. The outer edge of the protrusion 4 is welded to the inner wall of the lower cover 2, and the protrusion 4 is welded to the fastening structure 6. Cast iron has high strength and hardness, as well as a certain degree of wear resistance and toughness; welding can save metal materials, reduce structural weight, and the joint strength is close to that of the base material, resulting in high connection strength.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
