Abstract
The invention discloses a composite isolation gate upright post. The column comprises a column body part and a base, wherein the column body part is a glass fiber reinforced concrete column which sequentially wraps a column body UHPC layer and a glass fiber reinforced plastic layer from outside to inside; the outer part of the base is a basic UHPC layer, and the inner part of the base is filled with solid waste recycled foam concrete; the column body part is inserted into the solid waste regenerated foam concrete through the column slot. The invention adopts the UHPC with high light weight and high strength and good quality as the shell of the upright post, and protects the inner glass fiber reinforced plastic which is easy to age and the GRC composite material with relatively poor corrosion resistance. The glass fiber reinforced plastic is adopted to replace the internal tension steel bars and the internal is made of a high-performance GRC composite material, so that the integral structure has better mechanical property on the premise of further lightening the weight. In addition, the invention uses a large amount of low-carbon and solid waste materials, and is more environment-friendly than the existing products.
Description
Technical Field
The invention belongs to the technical field of traffic safety isolation devices, and particularly relates to a composite isolation gate upright post.
Background
The barrier in traffic safety facilities has a vital role. As a physical isolation measure, the isolation grating is widely applied to expressways such as expressways, and by arranging the firm isolation grating, pedestrians and animals can be effectively prevented from entering the road range, so that the road land is prevented from being illegally occupied, and the occurrence probability of serious accidents is reduced.
There are some common problems with the current common barrier columns. For example, conventional concrete column manufacturing processes require significant energy and resource consumption, along with significant carbon emissions. In addition, such spacer grid posts are themselves relatively heavy, and can cause a series of inconveniences in transportation, installation and maintenance links.
Other types of the existing isolation grid stand columns also have some defects, such as inconvenience in installation, weak durability and the like of stand column types such as steel stand columns and GRC composite stand columns.
Disclosure of Invention
The invention aims to provide a composite isolation gate upright post, so as to solve the problems of inconvenient transportation and installation and the like caused by high carbon emission, lower durability and large dead weight of the existing isolation gate upright post.
The composite isolation gate upright post comprises a column body part and a base, wherein the column body part is a glass fiber reinforced concrete upright post which sequentially wraps a column body UHPC layer and a glass fiber reinforced plastic layer from outside to inside; stirrups are arranged between the glass fiber reinforced plastic layer and the UHPC layer of the column body at intervals from top to bottom, and are connected with external hooks; the outer part of the base is a basic UHPC layer, and the inner part of the base is filled with solid waste recycled foam concrete; the top of the basic UHPC layer is provided with an upright post slot and a pouring hole; the column body part is inserted into the solid waste regenerated foam concrete through the column slot.
The column UHPC layer and the base UHPC layer are made of steel fiber reinforced cement-based composite materials, and the thickness is 20mm.
The thickness of the glass fiber reinforced plastic layer is 10mm, and the bottom edge of the glass fiber reinforced concrete column is 40mm.
Clamping grooves are symmetrically formed in the periphery of the upright post slot.
The depth of the column body part penetrating through the column slot and being inserted into the solid waste regenerated foam concrete is 300mm.
The stirrup is made of HPB300 steel bars, and the hook is made of Q235 type steel with galvanized surface.
The diameter of the pouring hole is 100mm.
The invention adopts the UHPC with high light weight and high strength and good quality as the shell of the upright post, and protects the inner glass fiber reinforced plastic which is easy to age and the GRC composite material with relatively poor corrosion resistance. The glass fiber reinforced plastic is adopted to replace the internal tension steel bars and the internal is made of a high-performance GRC composite material, so that the integral structure has better mechanical property on the premise of further lightening the weight. In addition, the invention uses a large amount of low-carbon and solid waste materials, and is more environment-friendly than the existing products.

Detailed Description
Example 1
Referring to fig. 1-3, the composite isolation gate upright comprises a column part 1 and a base 2, wherein the column part 1 is a glass fiber reinforced concrete upright 5 which sequentially wraps a column UHPC layer 3 and a glass fiber reinforced plastic layer 4 from outside to inside; the glass fiber reinforced concrete upright post 5 wrapped in the glass fiber reinforced plastic layer 4 further improves the mechanical properties such as the flexural strength, the splitting resistance and the like of the upright post while reducing the weight. Stirrups 6 are arranged between the glass fiber reinforced plastic layer 4 and the cylinder UHPC layer 3 at intervals from top to bottom, and the stirrups 6 are connected with external hooks 7; the stirrup 6 can fully promote the shear strength of stand to stirrup 6 is connected with the couple 7 of outside, makes couple 7 firm more difficult drop. The outer part of the base 2 is a basic UHPC layer 12, and the inner part is filled with solid waste recycled foam concrete 9; the two are combined to replace the traditional concrete foundation, and the strength and durability of the foundation are ensured on the premise of fully utilizing solid wastes. The top of the base UHPC layer 12 is provided with an upright post slot 11 and a pouring hole 8; the column part 1 is inserted into the solid waste recycled foam concrete 9 through the column slot 11.
The materials of the column UHPC layer 3 and the base UHPC layer 12 are steel fiber reinforced cement-based composite materials, and the thickness is 20mm. The thickness of the glass fiber reinforced plastic layer 4 is 10mm, and the bottom edge of the glass fiber reinforced concrete column 5 is 40mm. Clamping grooves 10 are symmetrically formed in the periphery of the upright post slot 11 and used for fixing the column body part 1, and mounting accuracy is improved.
