Description

Technical Field

[0001] The utility model belongs to the technical field of building construction moulds, in particular to a mould for processing ridge bends and roof lightning protection strips of ancient buildings. Background Art

[0002] There is no practice of installing lightning protection strips in the construction process of traditional cultural relics and ancient buildings. Therefore, in order to achieve the purpose of lightning protection, it is necessary to add a lightning protection system later. According to the current lightning protection specifications, when the building is rebuilt or the roof is completely rebuilt, the roof can be rebuilt and installed. Since the lightning protection system is constructed together with the roof, it will not affect the waterproofing of the roof, nor will it cause roof seepage. The structural connection is also relatively firm. However, due to the special roof structure of ancient buildings, the processing of the ridge bend is time-consuming and labor-intensive. There are many special-shaped structures of the lightning protection strips installed on the roof. The actual required shape often has many curved structures, which need to be designed and processed one by one according to the specific structural drawings, and the processing efficiency is low. Utility Model Content

[0003] The utility model overcomes the shortcomings of the prior art, proposes a processing mould for the lightning protection strip on the roof of an ancient building, and solves the problem of low processing efficiency of the ridge bend and the lightning protection strip on the roof of the ancient building.

[0006] The box body is also provided with a plurality of lightning strip processing structures, which are arranged in a matrix on the box body. The lightning strip processing structures include fixed columns and movable columns. The fixed columns are fixedly connected in the box body, and the movable columns are inserted into the fixed columns, and the tops of the movable columns are higher than the upper surface of the box body.

[0007] Furthermore, the second protruding column is arranged 1 / 3 upward from the lower edge of the ridge curved forming column.

[0008] Furthermore, the box body is a rectangular structure, including two upper and lower parallel first steel plates and two parallel second steel plates connected to both sides of the first steel plate.

[0009] Furthermore, the bottom of the fixing column is welded to the lower first steel plate, a plurality of through holes arranged in a matrix are provided on the upper first steel plate, and the top side wall of the fixing column is welded to the through holes.

[0010] Furthermore, the fixed column is a steel pipe and the movable column is a round steel.

[0011] Furthermore, the protrusion is square steel, and the bottom of the protrusion is welded to the second steel plate.

[0012] The beneficial effects of the utility model compared with the prior art are:

[0013] When processing the ridge bend, take the engineering round steel of appropriate length and mark it in the center, align the mark with the center of the ridge bend forming column in the mold, and then slowly bend the two sides symmetrically to the inside of the mold to ensure that it is just tangent to the first and second convex columns in the upper structure of the mold, until the end of the engineering round steel is parallel to the long side of the box, and the shape of the ridge bend can be quickly processed. At the same time, the ohm bend at the expansion joint of the lightning protection belt can also be made by this mold. When making the ohm bend, the horizontal section can be simmered into a horizontal shape at the second convex column.

[0014] There are many special-shaped structures of lightning protection strips on the roofs of ancient buildings. When processing the curved parts, a sketch is drawn according to the shape curve. According to the sketch size, a movable column of the corresponding shape is inserted into the box to outline the shape of the lightning protection strip. The movable columns in the remaining fixed columns are removed, and the engineering round steel is slowly simmered along the movable columns until it is formed.

[0015] The mold described in the utility model can be used for processing ridge bends, ohm bends and lightning protection strips, and solves the problem of low processing efficiency of ridge bends and roof lightning protection strips of ancient buildings. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] (3) The protrusion 2 and the second steel plate 102 are welded together after the centers are aligned.

[0036] The process principle of the processing mold is as follows:

[0037] (1) When processing the ridge bend, take the engineering round steel 8 to an appropriate length (actual required size), make a mark in the center, align the mark with the center of the ridge bend forming column 3 of the mold, and then slowly bend both sides symmetrically toward the inside of the mold to ensure that they are exactly tangent to the second convex column 5 and the first convex column 4 in the upper structure of the mold, until the end of the engineering round steel 8 is parallel to the long side of the first steel plate 101, and the ridge spanning bend sample shape is processed by this mold.

[0038] (2) The ohmic bend at the lightning protection belt passing through the expansion joint can also be made by this mold: when the ohmic bend is made, the horizontal section of the engineering round steel 8 is annealed into a horizontal shape at the second convex column 5.

[0039] (3) There are many special-shaped structures of lightning protection strips on the roofs of ancient buildings. When processing the curved parts (actual required shapes), a sketch is drawn according to the shape curve. According to the sketch size, a corresponding shape of movable columns 7 are inserted on the first steel plate 101 (the rest of the movable columns 7 are removed), and the engineering round steel 8 is slowly simmered along the movable columns 7 until they are formed.
