The utility model belongs to the technical field of packaging materials, and particularly relates to a wood angle bead which is characterized in that an angle bead body is made of wood, the angle bead body is in an L shape and comprises two side plates which are perpendicular to each other, the two side plates are integrally formed, and the wood angle bead further comprises rubber layers connected to the inner sides of the side plates through connecting structures. The composite corner protector takes wood as a main material, the characteristics of durability, high strength and the like of the corner protector can be ensured, and meanwhile, the rubber layer makes up the defect that the wood is easy to scratch the surface of the photovoltaic module, so that the composite corner protector with both strength and flexibility is formed.

The invention provides a lens module. The lens module comprises a lens seat and a lens group which are integrated, the lens holder is composed of a fixing piece and a lens frame, the lens frame is connected with the fixing piece, and the lens frame comprises a containing cavity and a bearing face located in the containing cavity. The lens group is arranged in the accommodating cavity and leans against the bearing surface so as to ensure that no relative displacement is generated between the lens group and the lens frame. As the lens group is of an integrated structure, the number of components is reduced, and relative displacement cannot be generated between the fixing sheet and the lens holder. Therefore, the problem that the alignment quality is affected due to the fact that the relative positions of the split lens barrel and the base or the heat dissipation substrate deviate in the assembling process in the prior art can be avoided.

The invention relates to the technical field of special-shaped frame building construction, in particular to a frame structure building main body construction method which comprises the steps that a steel column is installed, the steel column comprises a lower section column and an upper section column, the upper section column is installed on the lower section column at an inclined angle, and meanwhile radial steel beams connected with the upper section column are synchronously installed. When the upper section column is obliquely mounted on the lower section column, the radial steel beams connected with the upper section column are synchronously mounted, so that the mounted position of the upper section column can be fixed by the radial steel beams, and the upper section column is not easily pulled by the arc-shaped steel beams to deform after being mounted; therefore, it is guaranteed that the fixing position of each upper section column and the corresponding lower section column is more accurate, the situation that due to the fact that the distance between every two adjacent upper section columns changes, the length of a final steel beam is not enough for erection is avoided, and the reliability and efficiency of a construction scheme of a special-shaped building structure are effectively improved.
