Reinforced concrete trays (RC, RC): types, sizes, table and parameters of trays for heating mains

Reinforced concrete trays, also known as RC or RC trays, are crucial parts of the heating main infrastructure. Heating systems can operate safely and effectively thanks to the support and protection that these robust, long-lasting trays offer to the pipes that carry steam or hot water. These trays can withstand heavy loads and environmental stresses because they are made of reinforced concrete, which makes them a dependable option for a range of construction projects.

Reinforced concrete trays come in a variety of forms, each intended to fulfill a particular function. While some trays are designed to withstand high pressures and temperatures, others are made to be more affordable or simple to install. The size of the heating main, the environment it will be exposed to, and the particular requirements of the project all play a role in the tray selection. Choosing the appropriate tray for a particular scenario can be made easier by being aware of the various types and their uses.

When thinking about reinforced concrete trays, size is yet another important consideration. To accommodate varying pipe diameters and to guarantee sufficient coverage and protection, these trays are available in a variety of sizes. Additionally, standardized sizing makes planning and installation simpler, resulting in more predictable and controllable project schedules. Comprehending the various sizes and knowing how to choose the right one is essential for the accomplishment of heating main installations.

Tables with tray dimensions and parameters are frequently used to aid in the selection process. These tables offer comprehensive details on the sizes, weight capacities, and additional features of different tray models. Engineers and builders can make well-informed decisions that meet the practical and technical requirements of their projects by consulting these tables. When these resources are used properly, the trays that are selected will function well in the given conditions.

To sum up, the construction and upkeep of heating mains heavily depend on reinforced concrete trays. To make sure they satisfy the requirements of every distinct project, great attention must be paid to their kinds, sizes, and particular specifications. By choosing and using these trays efficiently with the correct information and tools, heating systems can operate more safely and efficiently overall.

Classification of trays

The following types of reinforced concrete trays are separated based on their intended use:

1. Drainage.
2. Road.
3. Water drainage.
4. For heating mains.
5. Impassable channels.
6. Intertrack, inter-sleeper.
7. Cable, energy.

They are separated into three categories based on how they are laid:

1. Edge. They are installed to divert water flows from roads to slopes.
2. For telescopic. Used in the construction of garages, buildings.

Building materials are categorized based on their manufacturing process, which includes vibration pressing and vibration casting for reinforced concrete.

What are trays for heating mains?

Concrete structures known as heating main trays are intended to shield hot water pipes from environmental harm, liquid intrusion, corrosion, thermal insulation air leaks, and soil displacement. They act as a conduit for the installation of subterranean utilities and are crucial to the layout of drainage ditches, hydraulic structures, treatment systems, and collector block walls.

Products made of concrete work well on any surface. They are placed in regions with significant subsidence, high groundwater levels, and 9-point seismic zones.

Description

The primary parameters of reinforced concrete, production standards, and the use of building materials are governed by state standards.

The document states that following manufacturing, concrete products must function well and possess the following attributes:

• increased thermal and waterproofing;
• frost resistance;
• high level of resistance to any loads;
• water resistance;
• resistance to aggressive factors and groundwater;
• reliability.

The concrete used to make the trays needs to fulfill the following specifications:

1. Grade – not less than 300.
2. Tensile strength – over 70 MPa.
3. Size of filler granules – up to 15 mm.
4. Absence of surface-active additives in the manufacture of the mixture.

Reinforcement is also regulated by GOST 13015.0-83. The material’s strength is ensured by the utilization of robust and premium steel. Steel classes A-I, A-III, and Bp-I are found in the reinforcing frame.

Concrete covers are placed over the heating system’s main channels to promptly prevent any accidents that might happen while it’s in use.

Subtypes of sluices are separated based on how they are laid:

1. KL. Equipped with special ceilings.
2. KLP. Made with covers and reinforced concrete blocks resting on them.
3. KLS. A gutter system with blocks resting on each other, fastened with channels.

Blocks are placed on a sand cushion in a ditch. Goods have to come into direct contact with the ground; this has an impact on the structure’s dependability. Mortar is used to fill joints. One uses bitumen or another type of plastic waterproofing on soil that is structurally unstable.

In order to ensure load uniformity and prevent distortions, the earth is filled simultaneously from both sides. Blocks used in areas where there are aggressive factors should have a protective layer of a specific solution applied to the facade.

Because they provide longevity and protection for pipes and cables, reinforced concrete trays are crucial parts of heating main construction and maintenance. These trays are available in a range of sizes and styles, each tailored to fit particular requirements and environmental circumstances. It is essential to comprehend various parameters, including dimensions and load capacity, when choosing the appropriate tray for your project. Together with a useful table for quick reference, this post will give you a thorough rundown of the many varieties and sizes of reinforced concrete trays, ensuring you have all the knowledge you need to choose wisely for your heating main installations.

Marking of trays

The type of building material is indicated in the letter:

• standard size;
• permissible design load;
• length of gateways.

The model is abbreviated if there is a fractional value in the marking. The nominal standard length is half of the actual length. The designation "D" is used when producing a product that is no longer than 750 mm in length. Furthermore, details regarding the manufacturer and the manufacturing date are supplied.

Modern infrastructure cannot function properly without reinforced concrete trays, which offer heating mains dependable support and protection. They are perfect for a range of environmental settings due to their strength and durability, which guarantees long-term functionality and low maintenance.

To meet the needs of various projects, these trays are available in a range of sizes and types. The best option for a particular installation can be chosen with the help of knowledge about the precise measurements and specifications of each type of tray. In order to maximize performance and guarantee that the heating mains are sufficiently protected, this selection procedure is essential.

Engineers and builders can make well-informed decisions by looking over the tables and specifications of reinforced concrete trays. By doing this, the heating systems’ lifespan is increased and their efficiency is enhanced. For this reason, reinforced concrete trays are essential to preserving the dependability and integrity of heating mains in a variety of applications.
