Description

Embedded cable bracket

technical field

The utility model relates to a pre-embedded cable support, which mainly relates to a cable laying support used in urban cable trenches or railways, tunnels and bridges.

Background technique

Existing brackets for laying cables on urban cable trenches or railways, tunnels, and bridges mainly use expansion screws to fix metal brackets. It is inconvenient to replace, and the structure of the cable trench is often damaged during the installation process, or the appearance is damaged, and it is easy to rust, damage, or even cause electric shock accidents in humid and complicated environments.

With the needs of the development of electric power construction in cities and towns, there is an urgent need for a cable bracket with simple construction, safety, convenience, short construction period, high installation efficiency and low cost. This utility model pre-embedded polymer composite cable bracket came into being .

Contents of the invention

The purpose of this utility model is to provide a new type of pre-embedded cable support, which is made of polymer composite materials, overcomes the above-mentioned defects of the expansion screw iron cable support, and can ensure simple, safe, convenient and short construction period , high installation efficiency, low cost, and can improve the adaptability and bearing capacity of the support, it is a high-efficiency support that meets the existing requirements.

The utility model pre-embedded cable support includes a pre-embedded seat 11 and a support seat 12; it is characterized in that there is a cable placement groove 14 on the support seat 12; The outer covering is covered with a polymer composite material 2 , and a layer of glass fiber reinforced plastic material 3 is covered on the outer surface of the polymer composite material 2 .

The above-mentioned pre-embedded cable support has marks 13 on the outer surface of the pre-embedded cable support 1 and between the pre-embedded seat 11 and the support seat 12 .

In the above-mentioned pre-embedded cable bracket, the mark 13 is a protrusion.

In the above-mentioned pre-embedded cable bracket, the cable placement groove 14 is an arc-shaped groove.

In the above-mentioned pre-embedded cable bracket, there is a small notch 15 on the back of the cable placement groove 14 .

With the above-mentioned structure, the cable support can be pre-embedded in the brick wall during the construction of the cable trench, and the construction is simple, safe, convenient, short in construction period, high in installation efficiency and low in cost.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail:

The utility model is a new cable support of pre-embedded polymer composite material, which includes a pre-embedded seat 11 and a support seat 12; there is a cable placement groove 14 on the support seat 12, and the cable placement groove can be of various styles. The groove, as shown in Figure 2, is an arc-shaped groove; in a further way, there is a small notch 15 on the back side of the cable placement groove 14, so that the cables placed on the bracket seat 12 can be fixed with binding wires. Bind to facilitate fixation. On the outer surface of the pre-embedded cable support 1, there are marks 13 between the pre-embedded seat 11 and the support seat 12, which are used to mark the pre-embedded position and make all the pre-embedded cable supports regular; Fig. 1, Fig. 2 As shown, the mark 13 is a protrusion.

The utility model pre-embedded cable support 1 includes a steel bar 2, and the steel bar 3 is covered with a polymer composite material 2. The composite material is a patent No. 03114337.7, and the invention name is "a polymer composite material for manhole covers". The material mentioned above is covered with a layer of ordinary glass fiber reinforced plastic material 3 on the outer surface of the polymer composite material 2. With this structure, it has strong bearing capacity, low cost and corrosion resistance.
