The membrane structure roof（chapter2）Type1. Reverse tension membrane structure: reverse curved shape, or double curved saddle shape with tension and stability. Tension and stability arise from mechanical prestressing of the membrane plane and its linear boundaries.2. Coaxial bending tension membrane structure: coaxial bending shape, or double curved spherical shape with tension and stability. Tension and stability are created by the action of air or water pressure perpendicular to the membrane surface. Structures of this type include air-supported structures and inflatable structures.If you encounter any problems when making a parking shed, you should consult a professional membrane structure parking shed production technician to ensure safety and save energy.FeaturesThe tarpaulin of the membrane structure carport is made of PVC/PVDF/PTFE/ETFE, and the biggest feature of the membrane material is high strength, good durability, fire and flame resistance, good self-cleaning, not affected by ultraviolet rays, and long service life, generally 15- 30 years. With high transmittance, the transmittance is 13%, the reflectivity to heat energy is 73%, and the amount of heat absorption is very small. It is precisely because of the invention of this epoch-making membrane material that the membrane structure carport has become a modern permanent building 1. Durability: Due to the appearance of high-strength membrane materials and the application of tensioning technology, the ability of membrane structure carports to withstand wind and rain is unmatched by ordinary awnings. Some carports use permanent membranes, which can be used for 30 to 40 years.2. Artistic: In addition to the incomparable practical, durable, wind and rain-proof functions of ordinary awnings, the membrane structure awning is a sculpture, a work of art, giving people a beautiful visual enjoyment. Its softness, its curves, its hardness and softness, its rich shape, its whiteness and flawlessness, make people shine and have a long aftertaste.3. Economy: Research shows that the performance loss rate of vehicles parked in the open air for a long time is twice as fast as that of vehicles parked in the carport. The use of membrane structure canopy can truly protect your car and slow down the aging speed of your car. Economically speaking, a small investment can greatly extend the life of your mount.website:www.prefabhomes.comhashtag membrane structure roof hashtag hashtag hashtag structure building #

High altitude assembly method of

The grid is installed by high-altitude assembly method.
Firstly, the assembly bracket is erected at the design position, and then the grid components are lifted to the design position in the air by crane, and then assembled on the bracket.
This method sometimes does not need large lifting equipment, but the amount of assembled bracket is large and there are many high-altitude operations.
Therefore, it is more suitable for steel grid connected by high-strength bolts and made of section steel or steel pipe grid with bolt ball joints. At present, some steel grid structures are still constructed by this method.

Three mistakes in the installation of color house

Changing the design scheme of color house without permission

Usually, in order to save the construction period, the installation workers often do not install according to the design scheme, and change the design scheme of the color steel house without permission and simplify the design scheme.

Correction 3: Party B must explain to the installation workers the importance of the design scheme of the color steel house before installation, so as to avoid the workers cutting corners and the structural stability is not guaranteed.

mistakes in the installation of color house

Misunderstanding : the design size of the purlin in the color is not consistent with the actual installation size. For the purlin installation process of the color steel room does not conform to the design plan size, usually do not underestimate this installation detail, if the installation is not good, it will deform the roof panel, or even collapse the house.

Correction 1: when the steel frame is installed, ensure that the actual size is accurately measured from the purlin edge to the center, and the color steel plate is processed and installed.

Explanation on raw materials of

The following is a summary of the knowledge of these materials. I hope it will be helpful to friends who are .

The classification of steel quality grade is mainly based on the requirements of impact toughness ( V-notch test), and the requirements of cold bending test are also different.

(1) For class A steel, the impact toughness is not the required condition, and the cold bending test is only carried out when required by the demander.
(2) The AKV value is required to be no less than 27J at levels B, C and D, but the test temperatures of the three are different. The impact value at normal temperature (25 + - 5℃) is required for level B.
(3) Grade C and D require impact values of 0℃ and - 20℃ respectively.
(4) Grade B, C and D are also required to pass the cold bending test. In order to meet the above performance requirements, the chemical elements of different grades of steel are slightly different.

Explanation on raw materials of

Recently, we encountered a problem in the production and negotiation of two batches of steel structures.
One of the customer of Mongolia locomotive project requires Q345D material, and another customer of Mongolia refinery project requires Q345E material. Because these two materials are not common , the steel plant needs to coordinate production separately. We use a large number of projects completed in Mongolia to prove that Q355B is no problem in Mongolia, However, the customer insisted on using this material. We followed the customer's requirements and completed the production on time. Later, we did the experiments and knowledge accumulation of these two materials, especially the impact test of Q355E material at minus 50℃ can reach 220J. The customer was extremely satisfied.

Construction site stitching

① Tie rod: You can use splicing plate to add high-strength bolt (figure c) or end plate to add high-strength bolt (figure d).

② Compression rod: Welding (figure e, f) or upper and lower contact surfaces can be planed and topped to directly bear the pressure transmission force (figure g, h). When welding, the upper member must be grooved in advance in the factory, and the lower section (or upper and lower sections) has positioning parts (channel steel or angle steel) to ensure the correct position when welding. When the upper and lower contact surfaces are planed and the tops are tight and directly pressurized, they should be supplemented with a small amount of welds and bolts so that they cannot be misaligned. The splicing of the tension and compression rod should be calculated according to the principle of equal strength, that is, the splicing material and the connecting piece can transmit the maximum internal force of the broken section.

Several commonly used [splicing of components
Factory stitching

① Tie rod: Direct butt welding (figure a) or splice board with fillet weld (figure b) can be used. In direct butt welding, the quality of the weld must meet the first and second quality standards, otherwise the spliced board plus fillet weld should be used.

②Press bar: Direct butt welding (figure a) or splice plate with fillet weld (figure b) can be used.
When using spliced plates and fillet welds, the flanges and webs of the components should have their own spliced plates and welds, so that the force transmission is as direct and uniform as possible to avoid excessive concentration of stress. When determining the width of the web splicing board, leave enough space for the operation of the welding electrode when welding the longitudinal welding seam.
