Technical Field

[0001] The utility model relates to the field of guardrails, in particular to a guardrail with anti-resonance and noise reduction functions. Background Art

[0002] Guardrails are commonly found at the edge of building foundations, such as the edge of stands, stairs, and floors. The main function of guardrails is to achieve safety functions, and aesthetics and other effects are also considered on the basis of safety functions. In some theaters, concert halls, performance halls and other places, there are usually several layers of platforms to set up viewing platforms. Guardrails are required at the edge of the upper platform for safety reasons. Guardrails are commonly made of welded steel structures. In order to improve comfort, guardrails usually have arc surfaces. In terms of material selection, steel pipe structures are more commonly used. Steel pipe structures have arc surfaces to prevent corners from causing harm to personnel, and also have good structural strength.

[0003] For places with high requirements for sound quality, such as concert halls, when steel pipe structures are used to make guardrails, due to the hollow structure of the steel pipes, resonance may occur during the performance, resulting in undesirable sounds and affecting the performance effect. Utility Model Content

[0004] In order to solve the problem of undesirable sounds that may be generated when using steel pipe structures to make guardrails in places such as concert halls, the utility model provides a guardrail with anti-resonance noise reduction function, which avoids resonance and generation of undesirable sounds by filling fillers inside the steel pipe.

[0005] The technical purpose of this utility model is achieved through the following technical solutions:

[0009] Furthermore, the connecting end includes a first arc block and an angle adjustment end. The first arc block has an arc surface that fits with the outer side surface of the horizontal railing. An arc groove is provided in the middle of the arc surface of the first arc block, and an adjustment hole that passes through the first arc block is provided at the bottom of the arc groove; the width of the adjustment hole is smaller than the width of the arc groove, and the angle adjustment end includes a second arc block that rotates in coordination with the arc groove, and a rectangular sleeve connected to the second arc block. The second arc block fits with the arc groove of the first arc block and the arc length of the second arc block is smaller than the arc length of the arc groove; the rectangular sleeve passes through the adjustment hole; the end of the first connecting steel plate or the second connecting steel plate is inserted into the rectangular sleeve for connection and fixation.

[0010] Furthermore, the thickness of the second arc-shaped block is equal to the depth of the arc-shaped groove.

[0011] Furthermore, the arc surface of the first arc block is attached to the surface of the transverse railing and fixed by welding, and the second arc block is fixed to the first arc block by welding.

[0012] Furthermore, the first connecting steel plate is fixedly connected to the embedded bottom plate by welding.

DETAILED DESCRIPTION

[0024] The technical solution of the utility model is further described below in conjunction with specific implementation methods:

[0025] A guardrail with anti-resonance noise reduction function, such as Figure 1 As shown, it includes a transverse railing 1 with a hollow structure, a first connecting steel plate 2, and an embedded bottom plate 3. One end of the first connecting steel plate 2 is arranged perpendicular to the transverse railing 1, and the other end of the first connecting steel plate 2 is welded and fixed to the embedded bottom plate 3. The first connecting steel plate 2 is arranged obliquely relative to the embedded bottom plate 3; both ends of the transverse railing 1 have blocking ends, and the interior of the transverse railing 1 is filled with a foam filling structure. In this embodiment, the transverse railing adopts a circular steel pipe structure, and the blocking end can also be welded to the end of the circular steel pipe using a steel structure with a spherical surface, or other materials such as plastic or rubber ends, which are installed on the end of the circular steel pipe by bonding. The bottom of the embedded bottom plate is a square steel frame, the embedded bottom plate is welded and connected to the square steel frame, and the first connecting steel plate 2 is welded and fixedly connected to the embedded bottom plate 3. The square steel frame is fixed on the concrete base, and a decorative surface is installed on the outside of the square steel frame, such as a stone veneer, a wood veneer, a glass veneer, etc. The installation method can be a dry hanging form. The inclined first connecting steel plate 2 enables the transverse railing to be closer to the edge of the facing, so that people can more conveniently touch the transverse railing when approaching the guardrail.

[0026] In order to increase the height and protective effect of the guardrail, Figure 2 As shown, a layer of transverse railing 1 is arranged above the transverse railing 1, and a second connecting steel plate 6 arranged vertically is connected between the upper and lower transverse railings. Figure 2 shown.

[0027] To facilitate the connection, Figure 3 As shown, the positions where the first connecting steel plate 2 and the second connecting steel plate 6 are connected to the transverse railing 1 are respectively provided with connecting ends, and the connecting ends are provided with arc surfaces on the outer side surfaces corresponding to the transverse railings.

[0028] Specifically, Figure 4-Figure 6 As shown, the connecting end includes a first arc block 7 and an angle adjustment end 8. The first arc block 7 has an arc surface 9 that fits with the outer side surface of the horizontal railing 1. An arc groove 10 is provided in the middle of the arc surface 9 of the first arc block 7. An adjustment hole 11 that passes through the first arc block 7 is provided at the bottom of the arc groove 10; the width of the adjustment hole 11 is smaller than the width of the arc groove 10, and the angle adjustment end 8 includes a second arc block 12 that rotates with the arc groove 10, and a rectangular sleeve 13 connected to the second arc block 12. The second arc block 12 is provided with the arc groove 10 that fits the first arc block 7 and the arc length of the second arc block 7 is smaller than the arc length of the arc groove 10, so that the first arc block can deflect in the arc groove; preferably, the thickness of the second arc block is equal to the depth of the arc groove.

[0029] The rectangular sleeve 13 passes through the adjustment hole 11; the end of the first connecting steel plate 2 or the second connecting steel plate 6 is inserted into the rectangular sleeve 13 for connection and fixation, and the connection and fixation method can be welding, bolt fixing, rivet connection, etc.

[0030] During installation, after the rectangular sleeve 13 of the angle adjustment end 8 is passed through the adjustment hole 11, the arc surface 9 of the first arc block 7 is attached to the outside of the circular steel pipe and the first arc block 7 is welded and fixed to the circular steel pipe, and then the circular steel pipe is filled with a foaming filling structure. The foaming filling structure can be made of common materials such as polyurethane, polyvinyl chloride, polyethylene, etc., and foaming is achieved by adding a foaming agent. After the angle adjustment is completed, the second arc block 12 is welded and fixed to the first arc block 7. The second arc block 12 can be welded at the position of the adjustment hole 11 to avoid welding operations directly on the circular steel pipe after the foaming filling structure is filled.
