Abstract
The utility model relates to a core pipe for shaping a circular hole of a hollow light wallboard and belongs to light wallboard production auxiliary devices. The core pipe for shaping the circular hole of the hollow light wallboard is characterized by mainly comprising an outer pipe, an inner pipe, a pipe head, blocking sheets, a pipe tail and a drawing ring, wherein the inner pipe is a straight stainless steel pipe with a circular ring cross section and is laterally arranged, the inner pipe is in transition match with an outer polyvinyl chloride (PVC) pipe with a circular ring cross section and is correspondingly sleeved in the outer PVC pipe, the outer pipe is slightly shorter than the inner pipe, the blocking sheets are evenly welded on step surfaces at the circumference of the right end of the inner pipe, the stainless steel pipe head in a cone shape is welded at the right end of the inner pipe, the pipe tail which is cylindrical is welded at the left end of the inner pipe, a center blind hole is formed in the right portion of the pipe tail, and the drawing ring is welded on the left end surface of the pipe tail. The core pipe is long in service life and capable of improving production efficiency and qualities of the light wallboard.
Description
Technical field
The utility model belongs to Light trabs and produces servicing unit, especially relates to a kind of pore-forming core pipe of hollow light wall board.
Background technology
Prefabricated and the prefabricated construction of house parts batch production is the important symbol of modernization of the housing industry, because the hollow light wall board specification is carefully and neatly done, is easy to moulding, is convenient to mechanization production, and production efficiency is high; Add that the hollow light wall board size is large, module large, good integrity, can install by assembled, efficiency of construction is also high, and home and abroad is the first-selected inner wall product using it as housing industrialization invariably, and extensive use in architectural engineering.Hole on hollow light wall board is shaped and need to realizes by the core pipe, and core pipe in the past is tubular, and material is iron and steel, and each use all will be rinsed, and has used of a specified duration can to get rusty, and has reduced core pipe service life, affects the quality of tube drawing efficiency and Light trabs.
The utility model content
The purpose of this utility model is the core pipe that proposes a kind of hollow light wall board circular hole shaping use, not only simple in structure, easy to use, and durable in use, and flushing-free is enhanced productivity and the quality of Light trabs.
The purpose of this utility model is achieved like this: a kind of core pipe of hollow light wall board circular hole shaping use (the core pipe that is called for short circular hole shaping use), it is characterized in that: the core pipe of this hollow light wall board circular hole shaping use is mainly by outer tube, inner tube, tube head, catch, pipe tail and drawing ring form, this inner tube is that left and right is the stainless steel straight tube of annular to the cross section arranged, be the PVC outer tube that interference fits ground suit cross section also is annular on this inner tube, and the length of this outer tube is slightly less than the length of inner tube, and make this inner tube, the left side of outer tube is concordant, and the right side of outer tube is positioned at the left side of inner tube right side, even inner tube, form step surface between the right part of outer tube, the uniform catch that is welded on the circumferential step surface of inner tube right part, can stop that when loosing core outer tube skids off to the right, simultaneously, at the be welded stainless steel tube head of cone of the right-hand member of this inner tube, in addition, offer the pipe tail of central blind hole at be welded cylindrical and right part of the left end of this inner tube, and the external diameter correspondence that makes this pipe tail is greater than the external diameter of inner tube and is slightly less than the external diameter of outer tube, to stop that outer tube skids off to the left, welding drawing ring on the left side of this pipe tail, this drawing ring can take the shape of the letter U.
During use; by in the shaping erecting mould of the corresponding insertion of the core pipe of this circular hole shaping use hollow light wall board; when the hollow light wall board castable and initial set qualified after; carry out the demoulding; use the drawing ring on hoist engine connection-core pipe; then extract at leisure the core pipe out, then take mould apart, shift out hollow light wall board and carry out maintenance.
The core pipe of the hollow light wall board circular hole shaping use that the utility model proposes, not only simple in structure, easy to use, durable in use, flushing-free, and long service life, improved production efficiency and the quality of Light trabs
The core pipe of the hollow light wall board circular hole shaping use now in conjunction with the accompanying drawings and embodiments the utility model proposed is further described.
The accompanying drawing explanation
Fig. 1 is the main cross-sectional schematic of the core pipe of the hollow light wall board circular hole shaping use that proposes of the utility model.
Fig. 2 is that schematic diagram is looked on the right side of the core pipe of the hollow light wall board circular hole shaping use that proposes of the utility model.
In Fig. 1, Fig. 2: 1, outer tube 2, inner tube 3, tube head 4, catch 5, pipe tail 6, drawing ring.
The specific embodiment
From Fig. 1, in Fig. 2, can find out: a kind of core pipe of hollow light wall board circular hole shaping use (the core pipe that is called for short circular hole shaping use), it is characterized in that: the core pipe of this hollow light wall board circular hole shaping use is mainly by outer tube 1, inner tube 2, tube head 3, catch 4, pipe tail 5 and drawing ring 6 form, this inner tube 2 is the stainless steel straight tube of annular to the cross section arranged for left and right, be the PVC outer tube 1 that interference fits ground suit cross section also is annular on this inner tube 2, and the length of this outer tube 1 is slightly less than the length of inner tube 2, and make this inner tube 2, the left side of outer tube 1 is concordant, and the right side of outer tube 1 is positioned at the left side of inner tube 2 right sides, even inner tube 2, form step surface between the right part of outer tube 1, the uniform catch 4 that is welded on the circumferential step surface of inner tube 2 right parts, can stop that when loosing core outer tube 1 skids off to the right, simultaneously, at the be welded stainless steel tube head 3 of cone of the right-hand member of this inner tube 2, in addition, offer the pipe tail 5 of central blind hole at be welded cylindrical and right part of the left end of this inner tube 2, and the external diameter correspondence that makes this pipe tail 5 is greater than the external diameter of inner tube 2 and is slightly less than the external diameter of outer tube 1, to stop that outer tube 1 skids off to the left, welding drawing ring 6 on the left side of this pipe tail 5, this drawing ring 6 can take the shape of the letter U.
During use; by in the shaping erecting mould of the corresponding insertion of the core pipe of this circular hole shaping use hollow light wall board; when the hollow light wall board castable and initial set qualified after; carry out the demoulding, use the drawing ring 6 on hoist engine connection-core pipe, then extract at leisure the core pipe out; then take mould apart; shift out hollow light wall board and carry out maintenance, long service life, improved production efficiency and the quality of Light trabs.
