A kind of circular arc-shaped metal plate bag rod structure
Technical field
The utility model relates to the technical field of building decoration, specifically a kind of circular arc-shaped metal sheet-pile face or partial circle arc sheetmetal decorative cover or super large circular arc metal sheet composite wall surface.
Background technology
Prior art is for band large-scale metal plate Bao Zhu and ultra-large type circular arc metal sheet decorative cover, and splicing seams is all larger or misplace, and outward appearance is not beautiful; Some splicing seams silica gel or filler rod make up splicing defect.Processing technology for ultra-large type metal sheet abnormity decoration panel is loaded down with trivial details, and precision cannot ensure, production efficiency is low, and percent defective is high.
Summary of the invention
The purpose of this utility model is the circular arc-shaped metal plate bag rod structure providing a kind of improvement, it can overcome splicing seams in prior art all larger or dislocation, the some shortcomings that outward appearance is not beautiful.
To achieve these goals, the technical solution of the utility model is: a kind of circular arc-shaped metal plate bag rod structure, it mainly comprises cylinder, it is characterized in that: cylinder is wrapped with at least 2 circular arc wrapper sheets, L-type circular arc stereotype plate is lined with in circular arc wrapper sheet, the left and right side edge of often opening circular arc wrapper sheet is connected with cylinder by slotted-angle shelving, is provided with U-shaped reinforcing rib between adjacent L-type circular arc stereotype plate.
Further, weld bolt be connected by planting between circular arc wrapper sheet with L-type circular arc stereotype plate, L-type circular arc stereotype plate is provided with horizontal mounting hole, and slotted-angle shelving is provided with the longitudinal mounting hole matched with horizontal mounting hole, is provided with attachment bolt in horizontal mounting hole and longitudinal mounting hole.
During use, between L-type circular arc stereotype plate, weld U-shaped reinforcing rib, circular arc wrapper sheet has and plants weldering bolt, guarantee that circular arc wrapper sheet appearance and size is accurate.L-type circular arc stereotype plate machined horizontal mounting hole, slotted-angle shelving machined longitudinal mounting hole, be easy to in-site installation, and ensure that circular arc wrapper sheet is spliced smooth up and down, close joint docks.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model will be further described.
Label in each accompanying drawing is expressed as follows:
1 circular arc wrapper sheet, 2L type circular arc stereotype plate, 3 slotted-angle shelvings, 4 setscrews, 5 attachment bolts, 6U type reinforcing rib, 7 plant weldering bolt.
A kind of circular arc-shaped metal plate bag rod structure described in the utility model, it mainly comprises cylinder, its difference with the prior art is: cylinder is wrapped with at least 2 circular arc wrapper sheets, L-type circular arc stereotype plate is lined with in circular arc wrapper sheet, the left and right side edge of often opening circular arc wrapper sheet is connected with cylinder by slotted-angle shelving, is provided with U-shaped reinforcing rib between adjacent L-type circular arc stereotype plate.Weld bolt be connected by planting between circular arc wrapper sheet with L-type circular arc stereotype plate, L-type circular arc stereotype plate is provided with horizontal mounting hole, and slotted-angle shelving is provided with the longitudinal mounting hole matched with horizontal mounting hole, is provided with attachment bolt in horizontal mounting hole and longitudinal mounting hole.One end of slotted-angle shelving is fixedly connected with cylinder by setscrew, and the other end forms removable connection by attachment bolt with circular arc wrapper sheet.Cylinder is wrapped with at least multiple circular arc wrapper sheets, is connected between the circular arc wrapper sheet of top and the circular arc wrapper sheet of below by attachment bolt; The left and right side often opening circular arc wrapper sheet is provided with flanging, and flanging place is provided with corresponding slotted-angle shelving.
In enforcement, the left and right side often opening circular arc wrapper sheet is provided with flanging, and flanging place is provided with corresponding slotted-angle shelving.Circular arc wrapper sheet 1 and L-type circular arc stereotype plate 2 weld bolt 7 be connected by planting, and weld U-shaped reinforcing rib 6, support prevent distortion to circular arc wrapper sheet between upper and lower L-type circular arc stereotype plate 2; Mixed earth cylinder or metope pass through setscrew 4 fixed angles steelframe 3, slotted-angle shelving 3 machined longitudinal waist-shaped hole;
L-type circular arc stereotype plate 2 has waist-shaped hole, and upper and lower two blocks of circular arc wrapper sheets 1 reach close joint by attachment bolt 5 and connect.Two blocks, left and right circular arc wrapper sheet 1 is linked together by attachment bolt 5 and respective slotted-angle shelving 3, and adjustment left-right and front-back distance, the close joint that can reach the two blocks of circular arc wrapper sheets 1 in left and right connects.Be easy to in-site installation, and ensure that circular arc wrapper sheet is spliced smooth up and down, close joint docks.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that the utility model is specifically implemented to be confined to these explanations above-mentioned.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
