The application provides a die and a manufacturing method of a duct piece. The method for manufacturing the mold and the duct piece of the present application will be described in detail with reference to the accompanying drawings. The features of the examples and embodiments described below may be combined with each other without conflict.
Fig. 1 is a schematic perspective view of a mold 10 according to an exemplary embodiment of the present application. Referring to fig. 1, the present application provides a mold 10 for manufacturing a segment, where the mold 10 may be used for manufacturing a tower tube segment of a wind driven generator and manufacturing a subway tunnel segment. The cross-sectional shape of the segment is not limited to a circular truncated cone, but may be circular, polygonal, triangular, etc. The mold 10 includes a base 11, a main mold plate 12, and side mold plates 13.
The base 11 is used to support and connect mold parts such as a master 12 and side 13. Wherein the base 11 may be a steel casting. In some alternative embodiments, the base 11 is provided with a plurality of openings 18, so that the weight of the whole die 10 can be reduced on the basis of ensuring the supporting strength of the base 11, and the transportation is convenient. The main template 12 is provided on the base 11 and includes a first template 14 and a second template 15. The first template 14 and the second template 15 can be made of carbon steel materials, wherein the inner surfaces of the first template 14 and the second template 15 are finish machining surfaces, so that the precision of the key matching surfaces of the duct pieces can be guaranteed through design, the quality of the duct pieces produced by pouring is easier to control, and the quality of the duct pieces produced by pouring is higher. In some alternative embodiments, the first template 14 and the second template 15 may be curved to form various shapes such as circular arcs, which is not limited in this application. The first template 14 is disposed above the second template 15 in a retractable manner, and is detachably disposed on the base 11. The first template 14 being disposed above the second template 15 in an openable manner includes a case where the first template 14 is covered above the second template 15, and the first template 14 is not covered above the second template 15. The first template 14 not being covered over the second template 15 may refer to the first template 14 being detached from the base 11, or may refer to the first template 14 being opened by rotation. The first template 14 is one of an inside template corresponding to an inside surface of the segment and an outside template corresponding to an outside surface of the segment, and the second template 15 is the other of the inside template and the outside template. The side form 13 extends upwardly from the second form 15 and is disposed around the second form 15 along an edge of the second form 15. The side form 13 may be connected to the second form 15 or to the base 11. Wherein, the internal surface finish machining of sideform 13 and second template 15 because the internal surface of sideform 13 and second template 15 is the key mating surface of section of jurisdiction, so the precision of the key mating surface of section of jurisdiction can be guaranteed to the design for pour the section of jurisdiction quality that produces and control more easily, the section of jurisdiction quality of production is higher. In some alternative embodiments, the sideform 13 may be removably attached to the base 11, may be attached to the base 11 by bolting, etc. In other alternative embodiments, the second template 15 and the side template 13 are non-detachably disposed on the base 11, and the second template 15 and the side template 13 may be welded to the base 11. The side forms 13 may be integrally formed with the second form 15. When the first template 14 covers the second template 15, the first template 14, the second template 15 and the side templates 13 are jointly enclosed to form a pouring cavity 16, the first template 14 is provided with a pouring opening 17, the pouring cavity 16 is communicated with the pouring opening 17, and pouring materials such as concrete can enter the pouring cavity 16 from the pouring opening 17 formed in the first template 14 for pouring. The size of the opening of the pouring opening 17 along the circumferential direction of the first template 14 ranges from 0.5m to 1m, so that the speed of pouring materials such as concrete entering the pouring cavity 16 can be increased while the segment manufacturing shape is ensured, and the pouring efficiency is improved.
In the related art, the duct piece is cast in the vertical mold, on one hand, in the process of demolding the duct piece, the outer mold and the end mold of the vertical mold are required to be completely removed, the duct piece can be taken out, the process is complex, the time consumption is long, and the production efficiency is low. The outer die and the end die are large in size, and the disassembly, assembly and movement operations are usually hoisting operations, so that the difficulty of safety management and the consumption of energy sources are increased. And because the precision requirement of the key splicing surface of the duct piece is higher by taking the connecting side surface, the top surface and the bottom surface of the duct piece as the connecting side surface, the top surface and the bottom surface of the duct piece, the top surface of the duct piece is normally folded manually, and the precision of the top surface of the duct piece, namely the precision of the splicing surface, is not easy to control. Meanwhile, the outer die and the end die are required to be frequently disassembled and assembled and moved when the pipe piece is demolded, abrasion of the outer die and the end die can be caused, the precision of the splicing surface of the pipe piece can be not easily controlled, and therefore the precision of each time of assembling of the pipe piece can not be guaranteed to be uniform. On the other hand, the vertical mould has higher pouring height, smaller pouring opening, easy incomplete concrete vibrating near the bottom, limited vibrating mode for improving the density of the concrete, and high Jiang Zimi concrete is required to be adopted for production in order to ensure the quality of the pipe piece produced by pouring, and compared with common dry hard concrete, the high-strength self-compacting concrete has higher cost. And because the vertical mould is higher in height, in the pouring process, the lateral pressure of the concrete in the vertical mould to the mould is larger, and the phenomenon of mould expansion is easy to generate, so that the quality of the manufactured duct piece is poorer.
The first template 14 of the mould 10 provided by the application can be arranged above the second template 15 in an opening and closing manner, the second template 15 is arranged on the base 11, the first template 14 is one of an inner template corresponding to the inner side surface of the duct piece and an outer template corresponding to the outer side surface of the duct piece, the second template 15 is the other one of the inner template and the outer template, and the side templates 13 extend upwards from the second template 15 and are arranged around the second template 15 along the edge of the second template 15. So need not to dismantle sideform 13 and second template 15 after pouring the completion, only need remove first template 14, can take out the section of jurisdiction, simplified the drawing of patterns step of section of jurisdiction, the same reason only need cover first template 14 in second template 15 top, can begin the pouring production of next section of jurisdiction, improved work efficiency. The side templates 13 and the second templates 15 do not need to be repeatedly disassembled and assembled, and the inner side surface or the outer side surface of the pipe piece is used as the surface of the manual receiving surface, wherein the outer side surface and the inner side surface are not key matching surfaces of the pipe piece, the inner side surface or the outer side surface of the pipe piece is used as the surface of the manual receiving surface, the precision quality of the splicing surface of the pipe piece is guaranteed, so that the quality of the poured pipe piece is better, and the splicing effect of the pipe piece is better. In this embodiment, the first template 14 is an outer template corresponding to the outer surface of the segment, the second template 15 is an inner template corresponding to the inner surface of the segment, and the outer surface is a non-matching surface, which has low requirements on precision. Because the inner side surface of the tower cylinder needs to be matched with the elevator guide rail, the crawling ladder, the platform, the bridge frame and the like, the outer side surface of the tower cylinder is used as a plane of the manual receiving surface, and compared with the plane of the inner side surface of the pipe piece as the manual receiving surface, the quality of the produced pipe piece is better. The first template 14 of this application is one of the inboard template that corresponds the inboard surface of section of jurisdiction and the outside template that corresponds the outside surface of section of jurisdiction, and the second template 15 is another one of inboard template and outside template, so the height of mould 10 mainly depends on the thickness of section of jurisdiction for the height of mould 10 can set up lower, the installation is more stable, simultaneously, pours highly lower, can make concrete pouring back vibrating more abundant, be difficult for appearing situations such as pine, gas pocket, make the quality of section of jurisdiction more easily control, and need not to adopt high-strength self-compaction concrete, the cost is reduced.
In some alternative embodiments, the mold 10 includes a connecting portion 19 and a fixing portion 20, and the base 11 includes a base body 21, with the connecting portion 19 extending upward from the base body 21.
