Pay attention to the suitability of choosing ppe

With the continuous development of science and technology, LED electronic display gradually applied to all walks of life. It is reported that LED display screens serve as advertising media, accounting for more than 56% of the entire advertising media, and the response is also very good. LED display screen installation requirements and precautions are also many, then, LED display structure is how to install the construction?

Henan Mingxinyuan Technology Co., Ltd. introduced that the design of excellent display support structure colleagues can be called beautiful scenery in urban buildings, combined with the display line of sight requirements, as well as the geographical characteristics of the investment will usually be based on the construction site and building requirements Design the type of structure.

First, display support structure type 1, roof-type support structure in the actual use of wall-mounted LED electronic display due to occupy a large building facade, will affect the building's lighting, so the wall-mounted electronic display only Applicable to large commercial buildings such as shopping malls. The LED electronic display screens for office buildings and civil residential buildings with moderately high building height can only be designed on the top of buildings. The display support structure system should be classified as a roof display support structure.

2. Floor-standing support structure Floor-standing LED display screens are often located in city squares or important traffic intersections. Analyzing the force characteristics of the floor display support structure, we can see that the support structure should adopt the space steel truss structure. On the basis of setting up 4 steel columns to form a space lattice column. The upper screen part adopts a multi-layer horizontal space truss structure, which can not only meet the structural force requirements, but also satisfy the setting of the inspection pasغير مجاز مي باشدe.

3. The construction density of wall-mounted support structures is relatively large. Only a few areas can meet the construction conditions of floor-standing displays. The LED display has the advantages of playing dynamic picture advertisements, etc., and a large number of LED display screens need to be built in the bustling commercial areas of the city. According to building construction conditions, transformation conditions, and building height, LED display support structures attached to buildings are generally divided into wall-mounted display support structures and roof-top display support structures.

The wall-mounted display support structure is mostly fixed on the side of the main structure with a single-layer steel structure, and a maintenance pasغير مجاز مي باشدe is set inside. The display screens installed in Zhengzhou Bairong Trade City and Silicon Valley Plaza are wall-mounted.

Second, the load of LED electronic display using floor-standing, wall-mounted or roof-type need to calculate the permanent load, live load, wind load, snow load, ice load, seismic load and other load effects. The permanent load shall be included in the screen self-weight load, and the live load shall consider the maintenance load involved in the screen body overhaul. The load combination coefficient should meet the specification requirements.

The self-oscillation cycle of the wall-mounted or roof-top display should be integrated with the main structure. Usually, the main structure self-vibration cycle can be used to calculate, and the effect of the high vibration type on the roof-top support structure can be analyzed. The calculation of wind load should be designed and analyzed according to the envelope structure, and the large support structure should be analyzed in detail according to the specific structure. The calculation of seismic load should consider the effect of bidirectional horizontal earthquake and vertical earthquake. The influence of vertical seismic action under rare earthquake should be especially considered for the wall-support structure.

Third, the structure selection 1, roof support structure Roof support structure needs to be combined with the original roof layout design, make full use of the original body structure system to bear the load to optimize the roof type of supporting structure system is very important. Generally, a variety of structural forms such as plane truss, space truss, or grid structure can be used in combination with building modeling. The structural scheme is flexible and flexible, and finite element analysis software can be used for modeling, analysis and calculation. In view of the characteristics of light steel roof, attention should be paid to the special nature of the natural vibration cycle and the whiplash effect. It is advisable to perform finite element analysis on the building model of the roof support structure and the building to study the stress-strain characteristics of the support structure.

2. Floor-standing support structure The floor-standing electronic display support structure bears the load of the upper screen structure through the column connected with the foundation and can be analyzed and calculated according to the cantilever beam structure. The floor-standing support structure usually adopts single-column or double-column plus beam-type structure, and the other types can use suitable supporting structural system in combination with architectural modeling.

3. Wall-support structure The wall-support structure is anchored to the side of the main structure by means of steel nodes. Usually, frame-fixed nodes can be used. When the spacing between nodes cannot meet the requirements, the frame beam can be used as an auxiliary fulcrum design position. The beam member is fixed on the support point to form a horizontal sheet structure system. The system bears the wind load transmitted from the display screen and assumes the maintenance load as a maintenance pasغير مجاز مي باشدe, and belongs to the main force system of the wall-mounted support structure. The screen body keel is arranged on the horizontal sheet structure system. 4. The display screen supporting structure with the steel member as the main component in the node analysis has a large number of connection nodes. The accurate design of the node is crucial to the overall structural safety performance.

The connection between the supporting structure and the concrete foundation adopts special embedded parts, and the connection with the main concrete structure adopts 40c-study anchor bolts and anchorage bars. The bolts are preferably used at the connection with the beam body. No expansion bolts may be used at all nodes. The number of anchor bolts set at the base node should meet the bearing capacity requirements and be arranged at equal intervals according to the principle of symmetry. The floor-standing support structure belongs to a cantilever type structure system, and its column root stress is relatively large; the wall-hung type support structure also belongs to a cantilever type structure system, and its node root stress is relatively large. For the stress distribution characteristics of the nodes connected to the foundation and the main structure, the optimal design is performed by using the method of processing the nodes at the root, which can effectively improve the stress of the nodes and reduce the amount of steel.

The accuracy of precision molds was generally 5 microns 10 years ago, and it has now reached 2 to 3 microns. Soon the precision of 1 micron molds will be available. This requires superfinishing. Metal processing mold industry will become larger and larger. This is due to the large number of mold-forming parts and the high production efficiency required to develop a multi-cavity model. The mold industry multi-functional composite mold will be further developed.

With the development of China's mold industry, the demand and requirements for mold products are gradually increasing. In addition to punching and forming parts, the new multi-functional composite molds also carry out assembly tasks such as lamination, tapping, riveting, and locking, and the performance requirements for steel materials are also increasing. And such improvement brings more impetus to the promotion of industry technology. In the future development of the industry, technological innovation is naturally the main factor, and technological upgrading is necessary. This is the most important condition for the rapid development of the industry and market demand.

At present, the domestic market has a large demand for medium-to-high-grade molds. Among them, household appliances, automobiles, and plastic products industries have the greatest demand for molds. It is understood that during the "Twelfth Five-Year Plan" period, the general trend of the mold market has been steadily increasing. However, domestic molds must meet the needs of users in terms of quality and delivery time.

The plastics and hardware mold industry is a traditional industry in China. It started earlier and became more and more mature. At the same time, it has also grown a group of small and medium-sized enterprises with potential. Under the current international competitive environment, relying solely on its original advantages can no longer meet the requirements of modern trade processes. The compression of غير مجاز مي باشدts and the need for maximum profits have accelerated the development of e-commerce as an inevitable choice for the domestic plastic hardware industry to cope with the challenges of economic globalization, seize the initiative for development, and enhance international competitiveness. E-commerce in the 21st century will surely become a hardware The main driving force for the growth of trade in the plastics machinery mold industry.

The leaders of metal processing mold enterprises, after determining the direction of development of the company, must seize the focus of leadership work, make clear the key work of the company, and do not waste energy on other insignificant matters, if one thing cannot, To promote the enthusiasm of employees, but also does not have a short-term or long-term promotion of the development of corporate profits, then this matter is unnecessary, it can be ignored.
