The utility model belongs to the technical field of elastic pad, especially weave bamboo raw fibre reinforced elastic pad, including inner core main part and cladding structure, inner core main part includes: composite fibre three -dimensional reinforcing layer, composite fibre three -dimensional reinforcing layer is formed with three -dimensional net -like structure that has three -dimensional support ability by natural fibre and synthetic fibre interlaced weaving, at least two interval distribution's support load layer, a plurality of elastic support unit, buffer layer, buffer layer fixed connection in the bottom side of the support load layer in the most lower layer, in the utility model, through natural fibre and synthetic fibre interlaced weaving enhance softness, through layered support and array elastic unit optimization stress distribution, improve softness and bending resistance, optimization local stress uniformity, enhance buffering support performance, retain bamboo raw fibre's moisture absorption and ventilation, antibacterial characteristics simultaneously, improve the comfort of use, be applicable to different weight user, and can extend to mattress, seat pad and other elastic pad scene, and the practicality is strong.

The present invention discloses a support mechanism for preventing and controlling impact ground pressure in a mine. An impact-resistant buffer seat is connected to the top end of a side support seat and the other end of the support top plate. The provision of the impact-resistant buffer seat can effectively improve the impact-resistant buffering capacity of the entire support device. A buffer support mechanism is also connected between the middle and upper part of the side support seat and the middle and upper part of the main frame seat. The buffer support mechanism can provide elastic buffering force between the side support seat and the main frame seat to ensure the ability to resist impact ground pressure. The hinge point between the impact-resistant buffer seat and the support top plate is a first hinge point, and the hinge point between the impact-resistant buffer seat and the side support seat is a second hinge point. The distance between the first hinge point and the second hinge point in the vertical direction is less than 1.2 times the thickness of the support top plate in the vertical direction, which can effectively ensure that the buffering stroke and angle of the impact-resistant buffer seat are not too large, thereby effectively ensuring the buffering support effect.

The utility model relates to the technical field of automobile rear floor cross beams, and discloses an automobile rear floor cross beam welding assembly structure which comprises a floor cross beam block, a carbon fiber layer and a polyamide fiber layer. The polyamide fiber layer is fixedly connected to the interior of the carbon fiber layer, the cellulose nanofiber layer is fixedly connected to the interior of the polyamide fiber layer, and the polypropylene fiber layer is fixedly connected to the interior of the cellulose nanofiber layer. According to the automobile rear floor beam welding assembly structure, the automobile rear floor beam is improved, so that the connecting and fixing capacity of the automobile rear floor beam is improved, and in the actual use process of the automobile rear floor beam, the automobile rear floor beam can be quickly and effectively fixedly connected according to needs; the influence of external force can be effectively resisted, and the use experience of the automobile rear floor beam welding assembly structure is improved.

The invention relates to the technical field of building anti-falling, in particular to an anti-falling device for an assembly type building protection platform, which comprises a protection platform, two fixing frames are symmetrically and fixedly mounted on two sides of the protection platform, the protection platform is connected with a protection net through a plurality of bolts, and a plurality of short rods are arranged on the protection net; falling personnel and objects are buffered through cooperation of the buffering main cushion and the side cushion, meanwhile, the rotating plate further supports the side cushion through the pressing plate, the further supporting effect on the falling personnel and objects is improved, the touch plate is pressed through the bottom frame plate, so that the side plate ascends to support the personnel and the objects, and the safety of the personnel and the objects is improved. Therefore, the damage to personnel and objects can be reduced.
