Description

A structure of estrusion pelletizer and it's assembling method}

The present invention relates to an assembly structure of a hollow extruded tube and a method for assembling the same, and in particular, to a plastic (or aluminum) tube that is hollow and extruded to a thin thickness, various attachments can be firmly attached with screws, and an extruded tube is used. When assembling a structure such as a fence railing panel is to be assembled more robust.

Frames installed in the building, or railing structures such as fence railings, balconies, stairs, etc., are mainly composed of square tubes made of plastic or aluminum. Since aluminum or plastic material forming the square tube is expensive, it is extruded into a hollow thin tube as shown in FIG. 1 for material reduction and weight loss.

When assembling such square tube, the two extruded tubes 10a and 10b are laminated to cross each other, and the upper extruded tube 10a folded through the hole 11 into which the screw is inserted in the upper surface of the upper corner tube where the screw is fastened. After drilling a screw hole in the bottom of the bottom and the upper surface of the lower extrusion pipe (10b) and screwed the screw (12) was assembled as shown in Figs.

However, when the pipes and the pipes are assembled with the screws in this way, the portion that is substantially subjected to the force is only the inner wall surface of the screw hole formed on the bottom surface of the upper tube and the lower tube. Therefore, because the thickness of the bottom surface of the upper tube and the upper surface of the lower tube is too thin, the inner wall surface making contact with the screw is too thin, so there is a drawback that is easily broken even in a weak impact. In addition, when attaching various attachments to the installed pipes with screws, the thickness of the pipes was too thin, and if the attachments were heavy or the load was transmitted through the attachments, they were also easily broken and the attachments fell easily from the pipes.

Meanwhile, in order to more firmly assemble the extrusion tube and cover the cross section of the extrusion tube exposed to the outside, a predetermined hole 13 to be screwed into the four inner ears of the hollow extrusion tube 10c as shown in FIG. 3 is extruded in advance. It was also used by molding. However, when assembling the pipes and the pipes overlapping each other horizontally and vertically, the surface and the surface of the thin plate must be assembled by screwing, so the assembly of the impact pipe was inevitable as in FIG. 1.

Until now, in attaching an attachment to an extruded pipe with a screw or attaching an extruded pipe to a column with screws or assembling an extruded pipe with an extruded pipe, the screw is usually screwed only on the coating plate of the extruded pipe. It was customary

The inventors break such a convention and use a long screw to turn the screw screwed into the skin plate of the extruded tube with a screwdriver, and screw it deep into the screw to penetrate the reinforcement plate in the extruded tube through the tunnel hollow or through the reinforcement plate in the extruded tube. In the case of a missing tube shape, the screw screwed from the skin plate penetrates through the hollow part of the extruded tube and is fixed to the ceiling plate inside the opposite skin plate, and the screw acts as a pillar to support the tunnel ceiling plate. Or to reinforce the epidermis and the epidermis to prevent shaking, as well as to find the screw that is stuck in the bottom plate long in the ceiling plate is found to be steadily firmly to come up with the invention.

In addition, the two screws with narrower diameters than the screws that are inserted into the tabs to reinforce the deflection of the screw column, that is, screwed into the inner reinforcement plate (or skin plate ceiling) through the hollow part and penetrate the skin plate, When the wall of the canyon standing up to form a canyon to wrap and support the screw, that is to say that the bending of the screw, that is, the pillar of the screw is completely reinforced and completed the present invention.

Therefore, by forming a plurality of support plate layers between the screw support pair walls of the gorge surrounding the screw of the present invention and successively penetrating the screw will obtain a solid effect such as screwing a solid thick plate.

The present invention uses the same principle as described above, is achieved by configuring a multi-layered screw support plate through which the thread of the screw, such as the saw blade, penetrates into the tab inside the surface to be assembled with the screw of the extruded square tube, more completely several layers It is achieved by forming a double-walled screw support twinwall narrowly narrower than the diameter of the screw to be inserted into tabs on both spaces of the screw through the hole, and by extrusion molding the screw support plates in multiple layers inside the double wall. Can be.

This assembly structure extrudes an infinitely long double-walled canyon into the surface of the extruded pipe to be assembled with screws. At any point, it will provide an infinite number of places to assemble freely (overlapping "＃").

In addition, the screw-supported twin walls of the screwed double wall are assembled by cross and vertical material, so that the infinitely horizontal gorge and the infinitely vertical gorge form a hole like a well sperm that crosses vertically. Therefore, the thread of the screw guided to the hole of the intersection points through the screw support twin wall which forms the double wall of the longitudinal member and the screw support twin wall which forms the double wall of the longitudinal member, respectively, and eventually tabs the screw in the direction of the screw on the wall blocked in all directions. It will be a solid assembly structure like a fixed structure.

In addition, the shape of the canyon by the screw support twin wall for screwing the screw on the surface of the pipe can be seen that the upper and lower canyons of the screw support twin wall forming the double wall are blocked by the upper and lower surfaces of the pipe that intersect the upper and lower portions of the double wall. It forms a long, multi-layered tunnel. Therefore, when the cross member and the cross member are cross-crossed together, the screw support pair wall or screw support plate of the cross member and the screw support pair wall or screw support plate of the multi layer of the cross member are vertically intersected and become a tunnel layer where the screws are overlapped with the cross member outer wall. Multi-layered screw support plate and screw support while drilling through the floor and inserting multiple layers of tabs on both sides of the screw support pair walls, and then through the bottom surface, and then through the ceiling surface of the cross lengths, and also multi-layered taps on the screw support pair walls. It is to provide a solid assembly structure and a method for assembling a plate with a thick solid plate such as the stacking height of several layers of screw support plates, and screwing together by drilling the last blocked bottom surface through the two walls.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

(Example 1)

Figure 4a is a cross-sectional perspective view of the extruded tubular body according to Example 1 of the present invention, Figure 4b is a cross-sectional perspective view of the screwed state to attach the attachment to the screw support plate of the extruded tubular body according to Example 1 of the present invention.

As shown, the extruded tubular body 20 forms a hollow rectangular tubular shape (deformable in various shapes such as a circular oval).

The extruded tubular body 20 is divided into a reinforcing wall formed therein and no reinforcing wall. Among them, the structure in which the screw support plate 23 is molded in the extruded tube body 20 having no reinforcing wall will be described.

In the extruded tube body 20 having no reinforcing wall, sidewalls 24a and 24b are separately formed on the inner side and a screw support plate 23 is formed between the sidewalls 24a and 24b. These screw support plate 23 is extruded to be positioned as planned according to the use of the extruded pipe (20). Of course, there may be several planned locations.

In addition, since the screw support plate 23 is located in the planned place, it is not necessary to mark the position from the outside, but it may be necessary to check the position from time to time depending on the construction situation, so that the surface of the extruded pipe 20 The display line may be formed by a line or a dot that indicates the position of the screw support plate 23. The screw support plate 23 is extruded together in the manufacture of the extruded tube (20).

And one screw support plate 23 may be installed, but in anticipation of the weight of the attachment (F) or the external force transmitted to the attachment (F) by selecting a sufficient number of screw support plate 23 and extruding any attachments (F) ) Can be attached firmly.

That is, when the number of screw support plates 23 and 24 is increased, the screw P is firmly supported because the force for supporting the screw P increases in proportion to the number of the extruded pipe bodies 20. This disperses and supports the external force acting on the screw (P) to each screw support plate 23, and because the threads are stuck to each screw support plate 23, it is possible to support the screw (P) with even greater force. It becomes the number. Therefore, even if the weight of the attachment (F) is heavier enough to withstand.

When attaching the attachment (F) such as steel to the extrusion pipe 20, the attachment (F) in close contact with the surface of the extrusion pipe 20 and penetrates through the extrusion pipe 20 to the screw support plate (23) screw (P) Puts. The screw P penetrates through the outer wall 21a, 21b surface of the extruded tubular body 20 through the tab and penetrates the screw support plates 23 therein. Since the screw support plate 23 reliably supports the screw P which is stuck, the attachment F is firmly fixed.

In addition, as shown in FIG. 5, the screw supporting plate 23 is formed by using the outer wall 21a, 21b, 21c, 21d surface of the extruded tubular body 20 itself without forming sidewalls 24a and 24b separately. It's okay. In this way, since the screw support plate 23 can be fixed even if the screw P is formed anywhere on the surface where the screw support plate 23 is formed, there is no separate display line displayed on the outside of the extruded tube 20. There is an advantage that is not necessary, and even if a change in the position of nailing or construction error occurs somewhat, even if it is enough to accommodate the error there is an advantage that can be firmly attached to the attachment.

On the other hand, the extruded tubular body 20 having the reinforcement wall described above is provided with a screw support plate 23 in harmony with the reinforcement wall.

That is, when only one reinforcing wall (22a) (22b) is formed horizontally inside the extruded pipe body 20 as shown in Figure 6a, the extruded pipe body (or lower) or the upper portion of the reinforcing wall (22a, 22b) ( 20) The sidewalls 24a and 24b connecting the upper and lower walls 21a and 21b to each other may be formed to be spaced apart from each other by a predetermined interval, and may be extruded into a structure constituting at least one screw support plate 23 therein. .

In addition, when the reinforcing walls 22a and 22b are formed crosswise, as shown in FIG. 6B, one side reinforcing wall 22b formed at the bottom is removed, and instead, a plurality of side walls 24a and 24b are spaced at predetermined intervals. It is possible to form a screw support plate 23 between the two side walls (24a, 24b).

In addition, when a plurality of reinforcement walls 22a and 22b are formed at regular intervals as shown in FIGS. 6C and 6D, a plurality of screw support plates 23 are provided between the inner side reinforcement walls 22b partitioned at positions where screws are screwed in. Mold out dogs. Of course, the screw support plate 23 may be formed between the outer wall (21c) (21d) surface and the reinforcing wall (22b) to the side of the extruded pipe 20 in addition to the position shown in the figure.

In addition, as shown in FIG. 6E, when the screw support plates 23 are extended to both sides of the side wall to be connected to both outer wall 21c and 21d surfaces of the extruded pipe 20, the area where the screw P is nailed is further widened. .

(Example 2)

Figure 7 is a cross-sectional perspective view of the screw support twin wall is installed in the interior of the extruded tube according to the second embodiment of the present invention, Figure 8a, 8b is screwed to the screw support pair wall of the extruded tube according to the second embodiment of the present invention 9A to 9E are cross-sectional views of a screw nailed to a pair of screw support pairs of the extruded tube of Example 2;

Reference numerals 21a, 21b, 21c, and 21d are upper and lower, left and right outer walls forming the extruded tubular body 20, and 22a and 22b are horizontal and vertical reinforcing walls.

As shown, the screw support pair walls 25a and 25b are formed on the inner surface of the extruded pipe 20 at the intended position and spaced apart from each other by a narrower diameter than the diameter of the screw P. In the case of the extruded tubular body 20 having no reinforcing walls 22a and 22b therein, the screw supporting pair walls 25a and 25b are the outer walls 21a and 21b of the extruded tubular body 20 that are mated with each other as shown in FIG. 7B. It is installed in a structure that connects or formed to have a predetermined length as shown in Figure 7a and then used to connect the end of the screw support plate (23).

By this structure, the screw (P) penetrating the attachment (F) in the extruded tubular body (20, 30) penetrates through the outer wall (21a) of the extruded tubular body (20) through the tab and both sides of the screw supporting pairs (25a) (25b) Pass through the tab) and then screw through the last screw support plate (23) through the tab.

Thus screwed screw (P) is supported by a large force by the outer wall (21a) and the screw support plate 23 and the both sides of the screw support pairs (25a, 25b) of the extruded tubular body (20). At this time, the force acting in the transverse direction is supported by the screw support pair walls 25a, 25b on both sides, and the force acting in the longitudinal direction is applied to the screw support pair walls 25a, 25b and the screw P locked therein. In addition to the binding force and frictional force of the screw thread is supported by the screw support plate (23) in the end to effectively support the forces acting in all directions.

In addition, both sides of the screw support pairs (25a, 25b) guides the way when the screw (P) is screwed in, so that the screw (P) can be attached to the attachment (F) precisely without being bent or bent in the other direction In addition to the function of supporting and guiding the screw (P), the screw supporting pairs (25a, 25b) may also perform a reinforcing wall function of the extruded tubular body (20).

Meanwhile, as shown in FIGS. 8A and 8B, a plurality of screw support plates 23 may be formed in the screw support pair walls 25a and 25b at regular intervals.

Due to this structure, the screw P passes through the attachment F as shown in FIGS. 9A, 9B, and 9C and penetrates through the outer wall 21a of the extruded tube 20 through a tab, thereby supporting both screw supporting pairs 25a and 25b. It passes through the tab out and screwed into the inner screw support plate 23 or the upper outer wall (21b) of the extruded pipe.

Therefore, the screw (P) is clamped to the outer wall (21a) (21b) and the screw support plate 23, both sides of the screw support pairs (25a) (25b) of the extruded tubular body 20 and clamped in the internal screw support plate (23) As a result, it is supported by greater force.

In addition, as shown in FIG. 9D, when the extruded tube 20 and the extruded tube 20 having the screw supporting pairs 25a and 25b formed therein intersect with each other, the screw P forms an outer wall 21a of the upper extruded tube 20. It penetrates through the inner threaded support pair wall (25a) (25b) through the tab with a tab, and through the inner threaded support plate (23) and the outer extrusion member outer wall (21b) through the tab through the tab, the extrusion located below The tube is drilled into the same structure and stuck together.

In this coupling structure, the screw support pair walls 25a and 25b of the extruded tubular body 20 are shaped to form a hole like a well sperm, so that the thread of the screw P guided to the hole of the intersection point is the twin wall of the longitudinal member. It becomes a rigid assembly structure that passes through tabs on the screw support pairs (25a) (25b) and the screw support pairs (25a) (25b) that form the double wall of the cross member. .

Furthermore, the shape of the screw support pair walls 25a and 25b for clamping the screw P on the surface of the tube is as if the small tunnel is stacked in multiple layers to form an integrated structure. Therefore, this structure has the same effect as combining the screw with a thick solid lumber when screwing (P).

In addition, as shown in FIG. 9E, the extruded pipe body 20 having the screw supporting pairs 25a and 25b formed therein may be applied to the plate body 30. When the plate 30 is used as a built-in material on the wall of the building or when used as a plate of a prefabricated building, the plate 30 is brought into close contact with the supporting pillar, and then the screw (P) is supported by a screw support pair wall (25a) (25b) from the outside. ), You can achieve a solid assembly.

In addition, in the case of reinforcing the screw support twin walls 25a and 25b formed inside the extruded tubular body 20 as shown in FIG. 9F, the reinforcement side walls 24a are provided on both sides of the screw support twin walls 25a and 25b as shown in FIG. 24b was formed to extend the upper screw support twin walls 25a and 25b to connect with the reinforcing side walls 24a and 24b on both sides to support the internal screw support twin walls 25a and 25b.

In this case, since the screw support pair walls 25a and 25b are supported by the reinforcing side walls 24a and 24b, the screw supporting pair walls 25a and 25b have a more robust structure.

The extruded tubular body 20 has a structure in which the screw support pair walls 25a and 25b and the screw support plate 23 are formed in the case where there is no reinforcement wall therein, but most extruded tubular bodies 20 have a reinforcement wall therein. Is formed. The reinforcing wall is designed in various forms in consideration of the mechanical surface according to the use of the extruded tubular body 20. According to the structure of the reinforcing wall, the screw supporting pairs 25a, 25b and the screw supporting plates 23 are harmoniously formed. do.

Representative structures of the screw supporting pairs 25a and 25b and the screw supporting plate 23 provided along the reinforcing wall will be described by way of example.

In the case where the reinforcement wall 22a is formed horizontally in the center as shown in FIG. 10A, one end of the screw support paired walls 25a and 25b is connected to one outer wall 21a of the extruded pipe 20, and the other end is reinforced in the center. To wall 22a. The screw support paired walls 25a and 25b formed as described above serve as a function of supporting the screw P and serve as an internal reinforcement function.

When the reinforcing wall 22a in the extruded pipe body 20 is comprised of the reinforcing wall 22b which transversely a center part and is divided vertically on both sides, as shown in FIG. 10B, the lower end between both reinforcing walls 22b is shown. Is connected to the lower outer wall (21a) of the extruded tubular body 20 and the upper end is formed in a structure by connecting to the reinforcing wall (22a) formed in the horizontal.

When it is desired to reinforce the screw support paired walls 25a and 25b in the extruded pipe body 20 in which the reinforcement walls 22a and 22b having the structure shown in FIG. 10b are formed as shown in FIG. 10B, the screw support paired walls 25a and 25b are provided. The screw support plate 23 is formed on both sides of the reinforcing walls 22a and 22b to support the screw support pair walls 25a and 25b even more firmly.

As shown in FIG. 10D, vertical reinforcement walls 22b are formed in pairs on both sides of the extruded pipe body 20, and the reinforcement walls 22a in the transverse direction are formed in pairs at regular intervals in the vertical direction. The formed structure may be achieved. Even in such a structure, it is possible to form the screw support pair walls 25a and 25b and the screw support plate 23 in the same structure as in FIG. 10C.

9F and the extruded tubular body 20 of FIGS. 10A to 10D are extruded with the extruded tubular body 20 in which the screw supporting plate 23 is formed and the screw supporting pair walls 25a and 25b. It is a structure that combines the advantages of the tubular body (20).

That is, the side walls 24a and 24b or the reinforcing wall 22b and the reinforcing wall 22b and the reinforcing wall 22b and the outer walls 21a and 21b of the extruded pipe 20, which are separately formed in the extruded pipe body 20, The screw support P 25a and 25b formed between the surfaces 21c and 21d and the screw support plate 23 connecting the upper and lower sides of the screw support twin walls 25a and 25b are respectively firmly screwed together. This is because it functions to support.

When the screw P is fastened by this structure, it penetrates through the outer wall 21a surface of the extruded pipe body 20 and presses out the tabs on both sides of the screw support pairs 25a and 25b so that the screw support plate 23 passes. Since it will be stuck while tapping to exert a high bearing force and the screw support plate 23 is to reinforce the screw supporting pairs (25a, 25b) will be able to exhibit a large bearing force. In particular, when the screw support plate 23 is made of a multi-layer it is possible to obtain even greater support force, it is possible to firmly support any attachment, such as a heavy weight attachment (F) or an attachment supporting a large external force.

As shown in the extruded tubular body 40, a screw support pair wall 25a, 25b in which a screw P is embedded and supported is formed, and a cap C is covered thereon. That is, the center surface of the upper surface of the extruded tubular body 40 is opened so that the top surface of the reinforcing wall 22a (which may be the screw support plate 23) in the horizontal direction in which the screw supporting pairs 25a and 25b are formed is visible. Cap fixing grooves 26 were formed on both sides of the upper surface of the 40.

Cap (C) formed an elliptical rounded surface and both ends (27) was formed in a slightly curled structure to be inserted into the cap fixing groove (26). The cap (C) is fastened to the screw (P) to the extruded pipe 40, when assembled to the other pipe is exposed to the outside of the screw head on the upper surface is poor appearance so to prevent this of the extruded pipe 40 The cap (C) was put on the upper surface.

Therefore, the extruded tube 40 and the extruded tube are intersected and the screw P is fastened so as to pass through the inner horizontal reinforcing wall 22a through the opening placed on the upper side, and then the other extruded tube is assembled, and then the upper outer wall 21b of the opening is assembled. Position both ends 27 of the cap (C) in the cap fixing groove (26) on the side, and then press it. By this operation, both ends 27 of the cap C are opened while being slid to the inner upper end of the cap fixing groove 26 and then inserted while being returned to the original shape from the cap fixing groove 26, so that they are fitted with a click sound. As the cap (C) is covered in this way, not only the head of the screw (P) is visible from the outside at all, but the cap (C) itself has a decorative effect, thereby forming a structure of the extruded tubular body (40) having a beautiful appearance. will be.

(25b) and the bottom surface formed with the screw support plate 23 is in close contact with the mating surface, and then drills the hole 28 so that the screw (P) on the opposite outer wall (21b) surface to the inner horizontal reinforcement (22a) ) Surface (or screw support plate 23 surface) is exposed. Then, the screw (P) through the hole 48 to penetrate through the screw support plate 23 and the screw support paired walls (25a, 25b) to be stuck in the other extruded tube or assembly. When the assembly is completed, the rubber hole (L) known to have a shrinking elasticity, such as rubber, is inserted into the through hole 28 to finish. Therefore, the head of the screw (P) is not visible at all from the outside can have a beautiful appearance.

(Example 5)

15 is a cross-sectional view showing the structure of an extruded tube according to Example 5 of the present invention.

As shown, a screw supporting pair wall 25a (25b) and a screw support plate 23 were installed in the extruded tubular body 50 having a large inside, such as a large pillar.

Screw support pairs (25a, 25b) to have a certain height and the screw support plate 23 is installed on the top or inside. As such, when the screw support pair walls 25a and 25b are installed, durability tends to decrease when a large force is applied after the screw P is lodged, and at this time, separate reinforcement side walls 24a, 24b, and 24c on both sides. 24d is formed to support the screw support paired walls 25a and 25b. The reinforcement side walls 24a and 24b and the screw support pair walls 25a and 25b may be connected by extending the screw support plates 23, and the reinforcement side walls 24c and 24d may be inclined to install the screw support pair walls 25a ( 25b) may be supported.

By installing the extruded tubular body 50 by this structure it is possible to easily connect the attachment (F) or various connection members with a screw (P) from the outside.

Particularly, the extruded pipe 50 may be used by filling concrete instead of reinforcing walls. In this case, the screw P may be hardly stuck by the concrete, but such screw supporting pairs 25a and 25b and the screw supporting plate 23 may be used. If it is formed, the screw (P) is easily pinched, there is an advantage that can be easily attached to the attachment (F) or the connection member.

As described above, the present invention forms a screw support plate and a screw support pair wall in which the screw taps out of the inside of the extruded pipe, thereby more firmly supporting the screw to assemble the attachment or the other extruded pipe, thereby achieving a more robust assembly. have. In particular, it is possible to obtain an effect such as screwing a member that is full inside by a multi-layered screw support plate, and there is an advantage in that any weight attachment can be firmly attached.

Also, if the extruded pipes are crossed to assemble structures such as fence railings to cross each other, the two walls form a well sperm, so that the forces acting in all directions can be complemented to each other so that the assembly between the extruded pipes can be maintained more firmly. It works. In particular, such a screw support pair wall and screw support plate not only makes a solid assembly of the attachment but also serves as a reinforcement function to improve the durability of the extrusion member.
