The invention relates to the technical field of sticking a dry film on a copper plate of a PCB (Printed Circuit Board), in particular to automatic dry film pressing equipment for the PCB. Comprising a storage rack, a hot-pressing roller, a hot-pressing wheel, a driving mechanism, a moving mechanism and the like, the PCB is placed on the storage rack, then the hot-pressing roller is driven by the driving mechanism to move, the hot-pressing roller can attach a dry film to the PCB, the hot-pressing wheel can move in a reciprocating mode through the moving mechanism, and the hot-pressing wheel is driven by the driving mechanism to move. Therefore, the hot pressing wheel can be in contact with and grind a dry film on the PCB. After the PCB is subjected to film pasting through the hot-pressing roller, the hot-pressing wheel can move left and right on a dry film of the PCB in a reciprocating mode, so that the dry film on the PCB is compacted through the hot-pressing wheel, air between the dry film and the PCB is expelled out, and local bubbles of the dry film can be completely expelled out after the dry film is compressed again through the hot-pressing roller and the hot-pressing wheel subsequently. Therefore, the dry film is prevented from wrinkling.

This invention provides a water-based coating for anti-slip and heat-resistant bamboo mats. The coating comprises a water-based penetrating primer layer, a water-based colored topcoat layer, a water-based water-resistant and heat-resistant coating, and a water-based anti-slip and wear-resistant coating. These four layers are sequentially applied to a bamboo substrate. This invention consists of four coating layers, which, when applied to a bamboo substrate, endow the bamboo product with excellent anti-slip, wear-resistant, water-resistant, and heat-resistant properties.

The pedal comprises an arc-shaped plate. The supporting pipe is in a single pipe shape, can be conveniently placed close to a forest tree and support the triangular ladder, and is suitable for being used beside the forest tree with many branches; compared with an existing straight pedal, the arc-shaped plate is larger in treading area, the effect of preventing people from falling is better, and the arc-shaped plate can also prevent people from sliding; the standing stability of people is improved, and the use angle of the triangular ladder is wider; the lower end of the supporting pipe is connected with the foot margin and the base plate, the supporting area of the lower end of the supporting pipe is large, the anti-sinking effect is good, and the base plate can prevent skidding and protect the ground when used indoors.

This application relates to an H-beam and its processing method, belonging to the technical field of hot-rolled steel sections. The H-beam includes an upper flange, a web, and a lower flange. The two sides of the web in the width direction are located between the upper and lower flanges. A support plate is provided between the upper and lower flanges. A positioning rod is provided on the web. Positioning holes for inserting and engaging with the positioning rod are provided on the support plate. A fixing component for confining the positioning rod within the positioning holes is provided on the support plate. When the H-beam is installed on a building, the positioning holes of the support plate are fitted onto the positioning rod, making the support plate perpendicular to the web. The fixing component confines the positioning rod within the positioning holes, thus fixing the support plate. When the upper and lower flanges bear the weight of reinforced concrete, the two ends of the support plate abut against the sides of the upper and lower flanges, respectively, thereby effectively reducing the deformation of the H-beam and improving its structural strength.

This invention relates to the field of deep foundation pit support construction technology, specifically a recyclable sheet pile construction device and method for deep foundation pit support. It includes two sheet pile walls, with four cylinders installed at the center of each adjacent side of the two sheet pile walls. Two baffles are fixedly connected to the telescopic ends of the eight cylinders. Three limiting sleeves are symmetrically fixed to each adjacent side of the two baffles. Three support rods are inserted between the six limiting sleeves. This invention features a fully modular, plug-in assembly system, requiring no welding or cutting. It remains intact after dismantling and can be reused repeatedly, significantly reducing construction costs and construction waste. Synchronous control of multiple cylinders allows for real-time adjustment of the top support force based on the soil pressure in the foundation pit, adapting to different depths and soil conditions. The support stability is extremely strong. The limiting rods and through-hole guide structure ensure coaxial support of the baffles, preventing misalignment. The sleeves and support rods distribute force evenly, eliminating stress concentration and preventing pile tilting.
