Description

Technical Field

[0001] This utility model relates to the field of building guardrail installation technology, and in particular to a guardrail fixing device. Background Technology

[0002] Installing guardrails at higher points on buildings effectively prevents accidental falls from these areas. Guardrails should possess sufficient structural strength to withstand external impacts, such as people leaning on them or wind, ensuring they do not loosen or collapse under normal use or extreme conditions. Guardrails are typically fixed to the top of the building's sill using screws or clamps.

[0003] However, during the construction of the retaining wall in building structures, it is generally fabricated later through rebar installation or prefabricated components are used for later installation, which cannot guarantee that the retaining wall and the main building structure form a unified whole. Due to the significant weight of the guardrail itself, there is a safety hazard of the guardrail and retaining wall overturning as a whole during installation and subsequent use. Utility Model Content

[0004] The purpose of this utility model is to provide a guardrail fixing device to solve the problem of guardrails and embankments overturning as a whole during installation and later use.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A guardrail fixing device is used to fix a guardrail to the curb of a building structure, wherein the guardrail fixing device includes:

[0007] The fastener has a first end fixedly connected to the top surface of the curb via a first connector, and the first end of the fastener is in contact with the top surface of the curb.

The second end of the fastener is fixedly connected to the main body of the building structure via a second connector, and the second end of the fastener is in contact with the main body of the building structure.

[0008] In one embodiment, the fastener is a Z-shaped plate, which includes an upper wing plate, a middle web plate, and a lower wing plate. The upper wing plate is fixedly connected to the top surface of the inverted curb as the first end of the fastener, and the lower wing plate is fixedly connected to the building structure as the second end of the fastener. The middle web plate is located between the upper wing plate and the lower wing plate.

[0009] In one embodiment, the intermediate web is parallel to the inner surface of the anti-reverse slope.

[0010] In one embodiment, the main body of the building structure is provided with the anti-reflective curb on both sides. The guardrail fixing device includes two fixing members. The first end of each fixing member is fixedly connected to the top surface of one of the anti-reflective curbs. A horizontal plate is fixedly connected between the second ends of the two fixing members through the second connecting member.

[0011] In one embodiment, the length of the first end of the fastener is greater than the width of the top surface of the anti-sill.

[0012] In one embodiment, a layer of cement mortar is filled between the fixing member and the inner side of the anti-reflector.

[0013] In one embodiment, the width of the fastener is 80mm-120mm.

[0014] In one embodiment, a surface layer is laid on the second end of the fastener.

[0015] In one embodiment, the first connector and / or the second connector are chemical anchors.

[0016] In one embodiment, the surface of the fastener is coated with an anti-corrosion coating.

[0017] The beneficial effects of this utility model are:

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1-3 As shown, this utility model provides a guardrail fixing device for fixing guardrails to a retaining wall that is fabricated or installed later in the building structure. The device includes a fixing member 1. The first end of the fixing member 1 is fixedly connected to the top surface of the retaining wall via a first connecting member 2, and the first end of the fixing member 1 is flush with the top surface of the retaining wall. The first end of the fixing member 1 is also fixedly connected to the guardrail. Specifically, the supporting columns of the guardrail are fixedly connected to the first end of the fixing member 1, and crossbars or balustrades can be installed between the supporting columns. The second end of the fixing member 1 is fixedly connected to the main body of the building structure, such as a connecting corridor or balcony, via a second connecting member 3, and the second end of the fixing member 1 is flush with the main body of the building structure.

[0029] The guardrail fixing device connects the retaining wall and the main body of the building structure into a whole through the fixing component 1, and installs the guardrail at the first end of the fixing component 1, thus avoiding the problem of the guardrail and retaining wall overturning as a whole during the installation and later use of the guardrail.

[0030] Specifically, such as Figure 3 As shown, the fastener 1 is a one-piece Z-shaped plate, including an upper flange 11, a middle web 12, and a lower flange 13. The upper flange 11 serves as the first end of the fastener 1 and is fixedly connected to the top surface of the curb. The lower flange 13 serves as the second end of the fastener 1 and is fixedly connected to the main body of the building structure. The middle web 12 is located between the upper flange 11 and the lower flange 13. Compared with ordinary plates, the one-piece Z-shaped plate has significantly improved bending resistance under external forces, enhancing the fixing effect of the fastener 1 on the curb. In areas frequently experiencing strong winds, the thickness of the middle web 12 can be appropriately increased to improve the overall bending resistance of the fastener 1.

[0031] Furthermore, the middle web 12 of the Z-shaped plate is parallel to the inner side of the inverted curb. For example, when the inner side of the inverted curb is at a 90° angle to the surface of the main body of the building structure, the included angles between the middle web 12, the upper flange 11, and the lower flange 13 are all 90°. This ensures that the Z-shaped plate connects the inverted curb and the main body of the building structure into a whole, while also ensuring that the Z-shaped plate fits as closely as possible to the inverted curb and the main body of the building structure, avoiding any protrusions from the Z-shaped plate that could affect the normal use of the building structure. The Z-shaped plate is usually made of a hard and corrosion-resistant metal material, such as stainless steel or galvanized steel. It can maintain its stability whether facing humid air or rainwater erosion, effectively extending the service life of the Z-shaped plate and ensuring that its fixing function can be performed stably for a long time.

[0032] Preferably, such as Figure 1 and Figure 2As shown, when there are curbs on both sides of the main body of the building structure, and guardrails need to be installed on both curbs, the guardrail fixing device includes two fixing parts 1. The first end of each fixing part 1 is fixedly connected to the top surface of a curb. A horizontal plate 4 is fixedly connected between the second ends of the two fixing parts 1 through a second connecting part 3. The horizontal plate 4 is usually set below the second ends of the two fixing parts 1. By fixing the two fixing parts 1 together through the horizontal plate 4, the curbs on both sides of the main body can be connected to the main body as a whole. When the guardrail is installed at the first end of the fixing parts 1 on both sides of the main body of the building structure, the guardrail, fixing parts 1, curbs and the main body of the building structure can be connected as a whole, which enhances the installation stability of the guardrail and avoids the problem of the guardrail and curb overturning as a whole during the installation and later use of the guardrail. For example, the thickness of the horizontal plate 4 is 8mm, the width is 50mm, and the length is determined according to the width of the building structure. Its specific dimensions can be adjusted according to the actual situation of the construction site, which will not be elaborated here.

[0033] Preferably, a surface layer 5 is laid on the second end of the fastener 1. The width of the surface layer 5 is the same as the width of the main body of the building structure. The surface layer 5 is usually a cement mortar surface layer. Cement mortar has good plasticity and adhesion, and can adhere well to the surface of the second end of the fastener 1, thus providing a relatively stable and flat base layer for subsequent construction operations. The surface of the main body is usually covered with floor tiles or other structures according to design requirements. The laying of the surface layer 5 makes the surface of the building structure flat and will not affect the normal use of the building structure due to the addition of the fastener 1.

[0034] Furthermore, such as Figure 1 As shown, the length of the first end of the fixing member 1 is greater than the width of the top surface of the retaining wall. Since the guardrail is installed at the first end of the fixing member 1, compared to installing the guardrail directly on the narrower top surface of the retaining wall, this design, where the length of the first end of the fixing member 1 is greater than the width of the top surface of the retaining wall, increases the working surface for installing the guardrail and further enhances the installation stability of the guardrail. Specifically, as... Figure 1 As shown, since the length of the first end of the fastener 1 is greater than the width of the top surface of the curb, there will be a certain gap between the fastener 1 and the inner surface of the curb. Therefore, the guardrail fixing device also includes a cement mortar layer filled between the fastener 1 and the inner surface of the curb, so that the connection between the fastener 1 and the curb is tighter and more secure.

[0035] Optionally, the width of fastener 1 is 80mm-120mm, ensuring that the guardrail can be stably installed at the first end of fastener 1, while saving the materials required to manufacture fastener 1 and avoiding waste of resources. Specifically, the first end of fastener 1 is 120mm long, 80mm wide, and 8mm thick, and the second end of fastener 1 has the same length, width, and thickness as the first end. The guardrail typically includes a support post, with a 100mm long and 80mm wide galvanized steel plate connector at the bottom of the support post. This connector is fixedly connected to the first end of fastener 1 and to the curb via a first connector 2. Since a width of 80mm-120mm for the galvanized steel plate connector is sufficient for the stable installation of the guardrail, a width of 80mm-120mm for fastener 1 is sufficient. Furthermore, the widths of the first and second ends of fastener 1 are determined based on the width of the galvanized steel plate connector at the bottom of the support post, and the height of fastener 1 is determined based on the height of the curb of the building structure, which will not be elaborated further here.

[0036] Optionally, the first connector 2 and / or the second connector 3 are chemical anchors. Anchor holes are provided on the galvanized steel plate connectors at the bottom of the guardrail support columns, the first and second ends of the fixing member 1, the top surface of the retaining wall, the horizontal plate 4, and the main body of the building structure for installing chemical anchors. The chemical anchors are tightly bonded to the screw and the substrate using chemical agents. Relying on the adhesive force between the chemical anchor and the substrate, as well as the screw's own pull-out and shear resistance, the galvanized steel plate connectors, fixing member 1 or horizontal plate 4 are fixedly connected to the concrete retaining wall and the building structure.

[0037] Optionally, regarding the fixed connection between the upper wing plate 11 and the top surface of the inverted curb, auxiliary connection methods can be added based on the first connector 2. For example, small anchoring protrusions can be set on the upper wing plate 11. These protrusions can be embedded into pre-set grooves on the top surface of the inverted curb during installation, forming a connection similar to a mortise and tenon structure, further enhancing the strength of the connection. For the fixed connection between the lower wing plate 13 and the building structure, an elastic buffer pad layer can be considered at the bottom of the lower wing plate 13 based on the second connector 3. When the building structure undergoes slight expansion and contraction due to temperature changes or other reasons, the buffer pad layer can absorb some of the deformation energy, preventing excessive stress from being transferred to the Z-shaped plate and the guardrail, thereby extending the service life of the entire guardrail fixing device.

[0038] Preferably, the surface of the fastener 1 is coated with an anti-corrosion coating, such as a paint coating, a zinc plating coating, or an organic coating. The anti-corrosion coating improves the corrosion resistance of the fastener 1, prevents the strength of the fastener 1 from decreasing due to rainwater erosion, and further improves the reliability of the guardrail fixing device.

[0039] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
