What is the role of the tension screw?

Tension screws are generally used in above-ground buildings, highways, bridges and other projects, on the one hand, to support and fix the formwork to prevent violent molding, and on the other hand, to control the thickness of the wall. When the tension screw is used, it is used in conjunction with the wall sleeve, which can protect the screw from being taken out smoothly in the later stage and not being damaged and reused again.

The tension screw is used for the tie between the inner and outer formwork of the wall formwork, bearing the side pressure and other loads of the concrete, ensuring that the spacing between the inner and outer formwork can meet the design requirements, and it is also the fulcrum of the formwork and its supporting structure!

It depends on the specific situation, in general, it plays a role in achieving a shock absorption, relatively speaking, it can achieve a very good effect, without any problems.

What is the effect on the pull screw? For the screw rod of the pull, its function is to add solidification and reinforcement.

The internal and external formwork of the tie is supported, preventing the concrete from expanding the formwork, so that the wall meets the design requirements, and the supporting casing can be reused, saving economy and reducing the bottom cost.

First, the water-stopping screw is a kind of tension screw The tension screw is another way we say about the wall screw, because the screw passes through the wall, both sides of the screw need to be wooden, steel pipe, mountain type card, nut and other fasteners to play a fastening role, forming a form of tension. The water-stopping screw is a kind of wall-piercing screw welded with a water-stopping place. It can be seen that the tie-in bolt is the wall screw, and the water-stopping screw is a kind of wall screw.

Second, the water-stopping screw is the one with the effect of water-stopping.

The usefulness of the screw.

It is mostly used in plastic molding equipment, such as plastic profile extruders, injection molding machines, etc. The screw and barrel are the core components of plastic molding equipment. It is the part that is heated and extruded and plasticized.

It is the core of plastic machinery. Screws are widely used in machining centers, CNC machines, CNC lathes, injection molding machines, wire cutting, grinding machines, milling machines, slow wire walks, fast wire walks, PCB drilling machines, engraving machines, engraving and milling machines, spark discharge machines, gear biting machines, planers, large vertical lathes, gantry milling and so on.

The main part of the pin screw is an ordinary screw, and the pin can be arranged in the melting section of the screw or in the falling groove of the metering section or the smooth cylindrical surface without the screw groove at the end of the metering section. The pins are set according to a certain arrangement, and the density can be unequal, and the number is unequal. The cylindrical pin is formed by fitting the pin into the hole of the screw; Square or diamond-shaped pins are formed by milling directly on the screw.

If these pins are set in the molten zone, the pins can break the solid bed, destroy the two-phase flow, stir the solid and liquid phases together, and increase the contact area between the final dissolved solid phase fragments and the contained materials, and promote melting. If the pin is set in the melt conveying area, its main function is to divide the material flow, increase the interface, change the direction of the material flow, and rearrange the flow beam. Divert and confluent many times to change the flow direction and homogenize the melt components and temperature.

The mixing section is an inward slotted structure arranged at the end of the homogenization section of the ordinary screw, and its outer diameter is equal to the outer diameter of the screw. The trench is divided into groups, and between each group is the confluence area of the material. The material is divided by the groove, to the confluence area of the meeting, and then divided, converged, the principle is similar to the pin type.

The characteristics of the separating screw are that in addition to the original screw pattern (called the main screw), a thread (called the additional thread) is attached to the molten section, and its outer diameter is slightly smaller than the outer diameter of the main thread, the lead of the main and secondary lines is different, and the secondary thread starts from the end of the feeding section (and is connected with the feeding section here), and after several threads, it gradually intersects with the main thread of the homogenization section. The depth of the screw groove and the thread lead of this screw are gradually changed from the beginning of the feeding section to the homogenization end, the thread lead gradually narrows from the width, and the depth of the screw groove gradually becomes shallow from the depth, so that the material can be compressed to the maximum.

Fixed, generally used with screws (caps).
