Design and construction of drainage pipe and tripod system

Design and construction of drainage pipe and tripod system

After the overall design plan and feasibility analysis report of the solar energy system project have been approved by Party A, the next work to be done is to further improve the detailed structural design of the overall system plan, or to include the detailed planning of the production, installation, and delivery of the project. The detailed plan cannot only stay at the schematic stage of the overall layout, but must be a detailed engineering design drawing accurate to the centimeter level. This detailed plan should provide the specific size of the collector and the building, the anchoring connection and the precise location of the interface, and the overall planning and layout of the piping system. The detailed plan involves the load distribution between the thermal insulation hot water storage tank and the tripod system and the load-bearing structure of the building, the specific design and actual construction plan of the anchoring installation node. The load distribution and anchoring node layout plan shall be submitted as a project to Party A and the architectural design unit for joint signature and approval after review. The system’s cold and hot water connection pipes, the connection with the building’s water supply and drainage pipes, and the construction responsibility for thermal insulation measures. Specific standards and requirements: The layout of concealed embedded parts and pipe network system should also be led by Party A, and the building water supply and drainage design unit shall conduct technical exchanges with each other. After consultation and coordination, the pipeline and footing of the solar energy system need to be embedded The location of nodes such as bolts and embedded steel joints connected to the building foundation should be listed and identified with identification codes and symbols. They should be clearly included in the construction drawings of the infrastructure; at the same time, relevant technical requirements, construction responsibilities, and inspection and acceptance standards should be put forward. The above-mentioned work involving other construction departments should also be under the general coordination of Party A, and the five parties of the building design, construction unit, solar installation department and engineering supervision unit shall be under the principles of clear responsibilities, clear responsibilities, unified standards, and consensus. , And jointly sign to clarify the cooperative relationship. Otherwise, the realization of the goal of real building integration cannot be guaranteed. In other words, architectural integration is definitely not an empty slogan or a product of unilateral subjective conjecture, but a “hand” that must be formed through “five-finger clasping.”

The design and construction cooperation problem of water supply and drainage pipes and tripod systems may be the most difficult problem for China’s solar energy to achieve building integration today; it is said that this problem is too small to mention, because there are just a few in the first place. The pre-embedded parts of cold and hot water pipes and signal lines, plus several sets of pre-embedded load-bearing anchor bolts steel joints, and the routine anchoring installation according to the technical requirements coordinates, is a small matter in normal building construction. Simple routine tasks to complete. However, in actual operation, because our current industrial system is engaged in architectural design regardless of the technical issues of solar building integrated installation, and engaged in solar system engineering design, there is no unblocked channel to advance the installation conditions of the solar system. Pass it to the architectural design unit in a targeted manner, and let it get the corresponding expression in the engineering construction drawings. There are many factors that cause the two parties to communicate inadequately. One of them is that the real estate construction unit failed to achieve the “three simultaneous” in the selection of solar equipment, architectural planning and design, and civil construction. Coupled with the lack of traditional and statutory procedural channels for information communication between industries, after arriving at the construction site, the interests and responsibilities involved in different units and industries will inevitably be entangled in this mess, and become one of China’s solar energy buildings today. In chemical engineering, the most difficult “old and difficult problem” to coordinate and deal with. It seems that there is not a “boss” who can speak effectively, that is, the government authority has made procedural and mandatory legal regulations that are legally binding on all parties involved, or a clear division of responsibilities, or its consequences and responsibilities can be prosecuted. The punitive measures are difficult problems that cannot be solved smoothly. If we ignore the above-mentioned procedural policy coordination measures and continue to let it go, China’s important measures for building energy efficiency-the goal of solar building integration, will continue to be difficult to achieve in the long term.

Regarding the design, installation and manufacturing of solar tripods, it is also necessary to draw the attention of system engineering designers that the solar tripod system is an important basic component that bears the load of the system and resists storms and snow pressure; it is a process between the solar equipment and the building. The connecting piece for anchoring installation; it is also a functional component to ensure that the solar energy equipment can receive solar radiation energy in the best working condition. In the design and manufacture of the tripod structure, these three elements must be fully embodied, and none of them is missing. My vacuum-tube household solar water heater, in the severe homogenization market competition, some manufacturers spend their minds on the exterior painting and beautification of the tripod in order to attract the attention of customers, trying to attract users by beautiful appearance. heartstrings. We have repeatedly emphasized that solar water heaters have the lowest visibility among household durable consumer goods. Some users have never seen what their own solar energy looks like for more than ten years, from the time the solar energy is installed in place to the obsolescence. Under the premise of ensuring the load-bearing system, resistance to wind, frost, rain and snow, and anchoring installation with the embedded bolts of the building, the tripod should be improved as much as possible and the parts should be protected from oxidation and corrosion. However, we must not put the cart before the horse, just make superficial articles, do not consider the weather resistance and the necessary strength at all, and try to hide the shame with a good one.

Solar tripod

The tripod can easily adjust the installation angle of the collector facing the sun within a certain range according to the geographical location of the user. This is an indispensable and very important basic function. The installation angle of domestic solar water heaters in China must be maintained by the manufacturer in the production workshop for a lifetime. The approach of taking all the north and south of the country violates the minimum scientific principle of solar energy utilization. As for the installation of top-heavy and temporary parking of solar water heaters with “override roofs”, “riding the roofs” and “hanging roofs” and label them as “integrated building installations”, this can only reflect the manufacturer. Ignorance, embarrassment and helplessness.

With the rise of high-rise buildings in China, the technology and methods of installing solar photovoltaic-light and heat utilization equipment on the facades of high-rise buildings, such as balcony guardrails, window sills, or left and right sides, have been put on the agenda. The installation of solar energy devices in these special parts of the building requires the understanding and technical support of the architectural design unit. In the architectural design, the solar installation position should be reserved. According to the standard geometric size and color of the solar collector or solar panel, the necessary coordination adjustments and reservation arrangements for the corresponding parts of the building should be made: the connection method of the anchor interface is unified. And implementation standards, pre-buried water circuit pipelines and anchor bolt joints, etc. are unavoidable issues that both parties need to negotiate and discuss together. In addition, solar designers must also use their brains and handle well in the aspects of system tripod windproof, earthquake resistance, lightning protection, anti-skid fall, equipment safety installation technology, tripod radium locking and prevention of accidental falling of parts and accessories. Various possible scenarios. The solar energy equipment installed on the specific exterior wall of these high-rise buildings must not have any potential accidents. From design, construction to project supervision, a position responsibility system with clear responsibilities and mutual restrictions must be established, and any plan, All must go through repeated communication, full discussion and consensus with the architectural designer and civil construction unit. Because any negligence can cause serious safety accidents that are unbearable and have a bad impact.
