Description

Technical Field

[0001] This application relates to the field of guardrails, and in particular to an ecological guardrail made of basalt fiber composite material. Background Technology

[0002] With advancements in technology and increased public awareness of environmental protection, eco-friendly guardrails will see wider application in urban construction. Eco-friendly guardrails are widely used in municipal construction projects such as parks, lawns, zoos, roads, and residential areas. They are also suitable for protective barriers along highways, railways, and bridges, as well as for safety protection in airports, ports, and docks. They not only effectively mitigate the urban heat island effect and improve the urban microclimate, but also enhance urban biodiversity and inject new vitality into the urban ecosystem.

[0003] However, ecological guardrails also have the following problems: insufficient strength, which may be damaged due to impact or other reasons; poor weather resistance, which is prone to corrosion and requires regular maintenance; and there may be problems such as unreasonable structure and weak connection during construction, which prevent the guardrails from achieving the required safety performance.

[0004] To address the above issues, it is necessary to propose an ecological guardrail made of basalt fiber composite material that is high in strength, has good weather resistance, and a simple structure. Utility Model Content

[0005] In order to make the ecological fence have the advantages of high strength, good weather resistance and simple structure, this application provides an ecological fence made of basalt fiber composite material.

[0006] The basalt fiber composite material ecological guardrail provided in this application adopts the following technical solution:

[0007] A basalt fiber composite material ecological fence includes multiple posts and multiple composite panels. The posts are vertically fixed to the ground, and the composite panels are placed between two adjacent posts. The composite panels are rectangular panels, and the posts and composite panels are made of basalt fiber composite material.

[0008] By adopting the above technical solution, columns are set on both sides of the composite panel in the horizontal direction to connect the columns to the composite panel, so that the composite panel can be vertically set on the ground by the columns. By using basalt fiber composite material to make the columns and composite panels, the columns and composite panels have better structural strength. The basalt fiber structure is stable and the structural strength remains constant after being exposed to sunlight and rain outdoors, thus having better safety.

[0009] Optionally, a slot is provided on the side wall of the column, and the composite board is inserted into the slot.

[0010] By adopting the above technical solution, slots are opened on the side wall of the column, allowing the slots to engage with the composite board, thereby enabling the composite board and the column to be spliced ​​together to form a continuous guardrail structure. The installation process is time-saving and labor-saving, and the structure is simple.

[0011] Optionally, the slots are configured as two, with two composite plates on each column.

[0012] By adopting the above technical solution, multiple holes are made on the posts, and a composite board can be inserted into each hole, so that multiple composite boards can be spliced ​​together to form a continuous guardrail structure, which facilitates installation.

[0013] Optionally, an adhesive is provided in the slot to bond and fix the column and the composite board together.

[0014] By adopting the above technical solution, adhesive is placed in the slot to bond the column and the composite panel together, thereby further improving the stability of the connection between the column and the composite panel.

[0015] Optionally, a base is provided at the bottom of the column for fixing it to the ground.

[0016] By adopting the above technical solution, a base is installed at the bottom of the column to fix it to the ground. The base has a large contact area with the ground, thus providing better support for the column.

[0017] Optionally, the base has multiple mounting holes for inserting bolts.

[0018] By adopting the above technical solution, mounting holes are opened on the base so that bolts can be inserted into the mounting holes, thereby making it easy and quick to fix the base on the ground, and making it convenient for users to install multiple columns on the ground.

[0019] Optionally, the composite panel has multiple ventilation holes that penetrate the composite panel.

[0020] By adopting the above technical solution and opening ventilation holes in the composite panel, when the composite panel is subjected to wind pressure, the wind can flow through the ventilation holes, thereby reducing the stress on the composite panel, reducing the probability of the composite panel falling off the column, and reducing the probability of the column losing its connection with the ground.

[0021] In summary, the beneficial technical effects of this application are as follows:

[0022] 1. By setting columns on both sides of the composite panel in the horizontal direction, the columns are connected to the composite panel, and the composite panel is then vertically set on the ground by the columns. By using basalt fiber composite material to make the columns and composite panels, the columns and composite panels have better structural strength. The basalt fiber structure is stable and the structural strength remains constant after being exposed to sunlight and rain outdoors, which has better safety.

[0023] 2. By opening ventilation holes in the composite panel, when the composite panel is subjected to wind pressure, the wind can flow through the ventilation holes, thereby reducing the stress on the composite panel, reducing the chance of the composite panel falling off the column, and reducing the chance of the column losing its connection with the ground; Attached Figure Description

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] This application discloses an ecological guardrail made of basalt fiber composite material, referring to... Figure 1 It includes multiple columns 1 and multiple composite panels 2. The columns 1 are vertically fixed on the ground, and the composite panels 2 are vertically arranged between two adjacent columns 1. The composite panels 2 are made of basalt fiber composite panels.

[0029] Reference Figure 1 Basalt fiber is a continuous fiber produced by melting basalt rock at 1450℃~1500℃ and then drawing it at high speed through a platinum-rhodium alloy stencil. It possesses excellent properties such as high strength, high temperature resistance, oxidation resistance, radiation resistance, thermal insulation and sound insulation, good filtration, and high compressive and shear strength. This fiber material not only exhibits outstanding mechanical properties, but its resistance to acid and alkali corrosion also far surpasses that of E-glass fiber and aramid fiber. Basalt fiber has a wide operating temperature range, from -260℃ to 880℃, and its low thermal conductivity provides excellent flame retardant properties. Furthermore, basalt fiber demonstrates good chemical stability, containing components such as K2O, MgO, and TiO2, which help improve the fiber's chemical corrosion resistance and waterproofing. Composite board 3 is made using basalt fiber and modified phenolic resin. Liquid modified phenolic resin impregnates chopped basalt fibers, and after curing, the liquid modified phenolic resin forms the board structure. Basalt fiber enhances the strength of composite board 3.

[0030] Reference Figure 1 and Figure 2 A slot 11 is provided on the upper side wall of the column 1, and the length direction of the slot 11 is parallel to the length direction of the column 1. The slot 11 is used to insert one end of the composite panel 2. The column 1 is vertically fixed to the ground, so that both sides of the composite panel 2 are inserted into the slot 11 respectively, thereby making the two columns 1 and the composite panel 2 locked together. This allows the composite panel 2 to be vertically fixed to the ground and to separate the traffic flow of vehicles and pedestrians.

[0031] Reference Figure 2 Two slots 11 are provided on the side wall of the column 1 and are flush with each other. A composite board 2 is inserted into each slot 11, so that multiple composite boards 2 form a continuous guardrail. A base 12 is provided at the bottom end of the column 1 for fixed connection to the ground. The base 12 is a plate structure and is perpendicular to the column 1. The base 12 has multiple mounting holes 121, the length of which is parallel to the length of the column 1. The mounting holes 121 are used to insert bolts, so that the base 12 can be installed on the ground.

[0032] Reference Figure 1 Multiple ventilation holes 21 are provided on the composite panel 2. The ventilation holes 21 penetrate the composite panel 2. The ventilation holes 21 are used to reduce the impact of wind on the composite panel 2, thereby reducing the probability of the column 1 being stressed and tipping over.

[0033] An adhesive is provided on the inner wall of the slot 11. The composite plate 2 is inserted into the slot 11 and fixed to the column 1 by the adhesive. The adhesive can improve the connection strength between the column 1 and the composite plate 2, thereby reducing the chance of the composite plate 2 coming out of the slot 11.

[0034] Reference Figure 1 The column corners are 100*100*30mm platforms with four bolt holes, and the column body is a solid column of 50*50*1000mm. The column material is basalt fiber profile.

[0035] Basalt fiber composite board is a type of basalt fiber molded board. The preparation method involves mixing chopped basalt fibers and a resin composition, followed by pre-curing and direct molding to form the composite board.
