This utility model discloses a splicing resin paper tube, relating to the field of paper tube technology. It includes a tube body and a splicing mechanism. The tube body has a composite structure, and the splicing mechanism is disposed between two tube bodies. The splicing mechanism includes a first metal tube, with a first annular groove formed on the side of the inner wall of the first tube body. The first metal tube is inserted into the inner wall of the first annular groove, and a fixing mechanism is provided between the first metal tube and the tube body. A supporting mechanism is provided at the end of the tube body away from the first metal tube. This utility model utilizes the first annular groove and the first metal tube. By simultaneously inserting the first metal tube into the first annular groove of both tube bodies, the two tube bodies can be spliced ​​together. This allows the first metal tube to support the splice joint, preventing compression deformation and improving the stability of the spliced ​​tubes.

The invention relates to a welding process for a rail joint. The welding process comprises the following steps: S1, welding for the first time; s2, slotting the surface of the welding seam; s3, welding for the second time; s4, repairing and cutting after welding; according to the welding process, after a splicing seam formed by butt joint of rail square steel base metal serves as a first groove to be welded for the first time, a notch is formed in the top face of a first welding seam, second welding is conducted on the notch to form a second welding seam, and a fusion line of the first welding seam and the base metal is covered with the second welding seam; two welding process parameters and the sizes of a splicing seam and a notch are optimally designed, so that cost increase, deformation and residual stress generation caused by transition welding or performance deterioration caused by insufficient welding are effectively avoided, the hardness and tensile strength of a welding seam are ensured, and the welding quality is improved through detection. The surface hardness, the impact resistance and the tensile strength of a rail joint formed by welding are higher than those of a square steel base material, and the effect is excellent and remarkable.

This utility model relates to the field of strength testing technology for steel-wood structures, and discloses a strength testing device for steel-wood composite joints. The device includes a frame, with a first displacement module at the lower end of the frame, and a sliding displacement frame mounted on the outer surface of the frame. This strength testing device for steel-wood composite joints uses an angle motor to drive a switching disk to rotate, enabling rapid switching between contact seats of different shapes and equidistant distributions on its lower surface. This allows for adaptation to the contact requirements of different structures, such as glued laminated timber (GLLT) splice joints, GLLT support joints, and GLLT-steel truss web member connection joints. For example, for rebar connection joints, contact seats adapted to the rebar distribution area are selected to simulate the collaborative stress of the rebar and the wood holes. For bolt-steel insert plate connection joints, contact seats adapted to the steel insert plate plane or bolt countersunk holes are selected to ensure a tight fit at the contact interface, avoid stress transmission distortion, and improve the simulation accuracy of the actual stress state of the joint.

The invention relates to a parchment table board pasting method, and belongs to the field of parchment, and the parchment table board pasting method comprises the steps that the surface of a part to be pasted with parchment is pretreated, so that the surface of the part is smooth; pre-splicing parchment paper to be pasted, and pre-treating seams so as to enable the seams to be matched; and an adhesive is attached to the surface of the pretreated part and / or the back face of parchment. According to the parchment table board pasting method, the surface of the part to be pasted with the parchment is polished to be smooth, the parchment is pasted after factors such as holes and nail holes influencing the pasting attractiveness are eliminated, the parchment is pre-spliced before pasting, the seam is pretreated, it is ensured that the seam at the splicing joint of the pasted parchment is narrow, and in addition, the surface of the parchment table board is not damaged. The splicing joint is ironed and polished immediately after pasting, the problem that the splicing joint is uneven is solved, the blistering phenomenon of the subsequent splicing joint is eradicated, and it is guaranteed that the splicing joint has high attractiveness.
