Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for forming a concrete gutter cover, a mold for the same, and a soundproofing buffer member attached to the gutter cover.

(Prior Art) In recent years, the amount of vehicle traffic has increased rapidly, and on narrow roads, 141 cars pass over the side ditches. Therefore, as the vehicle passes, the gutter cover bounces and generates noise, so gutter covers with a soundproofing buffer attached to the contact area with the hook of the 1M gutter, that is, the bottom of the cover, have come into circulation. Ta.

Conventionally, there have been two methods for attaching soundproofing shock absorbing members: one is to attach them to the factory-produced lid using adhesive in a later process, and the other is to attach the g-impact members integrally at the time of concrete pouring at the factory. However, considering issues such as time and installation strength, the latter method was superior.

However, even with the latter method, the concrete method was to pour concrete flat against the formwork. That is, after forming the mold, concrete is poured to the thickness of the gutter cover, and the top surface is finished with a border. After that, the buffer member is pushed into the surface of the poured concrete with the back side with the convex part for preventing peeling facing down, and the edges are finished again.
The method was to remove the mold after the concrete had hardened.

(Problem that the invention attempts to solve) The conventional methods described above have the following deficiencies.

1) Because of flat casting, the installation area of the formwork becomes large, and the work area is large, making it unsuitable for molding in large numbers.

2) With the flat pouring method, concrete must be poured little by little to the thickness of the gutter cover, making the work difficult and time consuming and inefficient.

3) The hardness of the concrete surface varies depending on whether or not the gravel of the poured concrete is close to the surface, making it difficult for the buffer member to remain in a horizontal state.

4) Since the area to be finished with a trowel was large, it took a lot of time to work and required a large number of workers.

The purpose of this invention is to provide a method for forming a concrete gutter cover, a molding form thereof, and a soundproofing buffer member to be attached to the gutter cover, which can further eliminate various defects than the conventional ones. .

It is.

(Means for Solving the Problems) Therefore, the method for forming a concrete gutter cover according to the present invention has the following configuration. That is, in the method for forming a side M lid that includes a soundproofing buffer member on at least the bottom portion, that side F
II. A molding frame is formed so that the top and bottom parts of the lid are molded in the vertical direction.

In the molding plate constituting the molding frame, at least four mounting parts are formed on the molding plate that molds the bottom part of the gutter cover, and a mounting convex part is formed on one surface of the buffer member to fit into the four mounting parts. form. Therefore, the buffer member is attached and fixed to the plate surface of the molded plate by fitting into both the concave and convex portions. Thereafter, concrete is poured into the molding chamber formed by the molding frame so as to partially bury the buffer member, and when the concrete hardens, it is removed from the mold together with the buffer member.

Furthermore, the concrete gutter cover molding frame according to the present invention is such that the surface and bottom portions of the gutter cover are formed in a vertical direction in the gutter cover molding frame that includes a soundproofing buffer member on at least the bottom portion. Form a molding frame. In the molding plate constituting this molding frame, the mounting convex portion formed on one surface of the buffer member is just fitted into the molding plate forming at least the bottom part of the gutter cover, and the member is attached to the molding plate. It is made up of four mounting parts that can be attached and fixed to the plate surface of.

Further, the concrete side tit forming form according to the present invention has the following configuration so that a large number of concrete molded products can be taken at the same time. That is, the molding frames of this mold are formed in a series so as to overlap in the thickness direction of the gutter cover to be molded, and the molds are opened by increasing the distance from each other in conjunction with the movement of the front and rear movable plates. be done. These molding frames include a bottom molding plate, left and right side molding plates that stand pivotally on both sides of the bottom molding plate, and a left and right side molding plate that is fixed to the bottom molding plate and stands as a partition between each molding chamber. It is formed by a partition molded plate.

Moreover, the soundproof buffer member for concrete gutter covers according to the present invention is used in the above-mentioned forming method and forming form. That is, it is a soundproofing buffer member that is attached to the bottom or side surface of a gutter cover, and a mounting convex portion is formed on the surface thereof for attaching and fixing the buffer member to the molding frame of the gutter cover. A means for preventing the member from peeling off from the concrete molded product is formed on the back surface portion or side surface portion. The mounting convex portions fit exactly into four mounting portions formed on a molded plate that is in the molding frame and forms the bottom or side surface of the gutter cover, and the buffer member is attached to the surface of the molded plate. It can be fixed.

(Function) First, on the plate surface of the partition forming plate that forms the bottom part of the gutter cover,
Attach the soundproofing buffer member in advance. At this time, the mounting convex portions formed on the surface portion of the buffer member are applied to the four mounting portions formed on the partition molded plate. If the four mounting parts are on the partition molding plate and are formed in the vertical direction,
Attach by sliding it downwards. In addition, when it is formed in the horizontal direction, it is attached by inserting it from either the left or right direction.

Once the installation of the buffer members and mold assembly are complete, concrete is poured into the molding chamber. The poured concrete is filled so as to partially bury the buffer member. When the concrete has hardened, the mold is opened and the molded gutter cover is lifted upward, and the buffer member is removed from the partition forming plate, and the concrete gutter cover with the buffer member is removed from the mold.

(Example) Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4. 1 in the figure indicates each forming frame 2 during concrete pouring.
This shows the entire concrete formwork of the multi-cavity type, which is tightened and then pulled apart to open the mold after forming, allowing the hardened molded product to be easily demolded. That is,
Left and right rails 4 are provided on a base 3 of this formwork 1. On this rail 4, there are front and rear movable plates 6 that move in parallel outward by the rotation of the front and rear threaded rods 5, and move in conjunction with the movable plates 6 to widen the distance between them to open the mold. , a large number of forming frames 2 are mounted. The movement of each molding frame 2 is guided by a fixed rod 8 that passes through a pipe 7 fixed to the center of the lower end of each molding frame 2.

Moreover, each molding frame 2 is formed in a series so that a large number of molding frames 2 are overlapped in the thickness direction of the gutter cover so that the surface and bottom parts of the gutter cover to be molded are formed in the vertical direction. and the second
As clearly shown in the figure, these molding frames 2 consist of a bottom molding plate that moves on a rail 4, and left and right side molding plates that rise and are supported by shaft supports 10 on both sides of the bottom molding plate 9. and,
A partition molding plate 12 is fixed to the molding plate 9 and stands to partition the molding chambers from each other.

First, the bottom molding plate 9 and the partition molding plate 12 will be explained. The former molds the side surface of the gutter cover to be molded, specifically, one side surface in which a drainage notch is provided, and the latter molds the side surface of the gutter cover to be molded, and Shape the bottom and top surface of the lid. That is, the latter partition molding plate 12 is one partition plate of the molding chamber formed by the molding frame 2, and is also the other partition plate of the molding chamber formed by the other adjacent molding frame 2. Therefore, the partition molding plate 12 functions as a molding plate for molding the bottom part of the gutter cover on its inner surface, and as a molding plate for molding its surface part on its outer surface.

At both ends of the inner surfaces of these molded plates 9 and 12, four mounting parts 1 are provided so that soundproofing buffer members 13 and 14 to be attached to the bottom or side surfaces of the gutter cover can be fixed.
5.16 is formed. The four attachment parts 15 and 16 are, for example, composed of a plurality of grooves cut in a straight line, and are inserted into the back of the molding plate 9 (toward the partition molding plate 12) or toward the lower end of the molding plate 12 ( (towards the bottom molding plate 9 direction)
It is extending. However, the shapes of the valley grooves that make up the recess 15 are different, and as shown in Figure fjS3, only the central groove is square, and the left and right grooves are irregularly shaped with sloped outer sides and narrow entrances. It is a groove. Also, the shape of the valley grooves forming the four parts 16 are the same, and the $4
As shown in the figure, the entrance has a tapered shape.

On the other hand, the soundproofing cushioning members 13 and 14 are usually called packings made of soft rubber, soft synthetic resin, etc., and on the back side there is a piece of material to prevent the cushioning members from peeling off from the concrete molded product. Equipped with means for In this embodiment, as clearly shown in FIGS. 5 and 6, a plurality of four tapered sections 17 and 18 whose entrances are narrowed serve as peeling prevention means. In addition, on the surface part, molded plates 9, 1
It is provided with a mounting protrusion 19.20 consisting of a plurality of protrusions that fit exactly into the mounting recess 15.16 formed in 2. That is, each of the protrusions constituting the mounting protrusion 19 has only the central protrusion having a rectangular shape, and the outer side surfaces of the left and right protrusions having sloped surfaces, so as to correspond to the grooves constituting the attachment recess 15. The tip has an unusually shaped ridge that spreads out. Furthermore, each of the protrusions constituting the attachment convex portion 20 is connected to the attachment concave portion 16.
The tip of each has a tapered protrusion that widens to correspond to the grooves that make up the groove. Here, the reason why the connection between the mounting convex part 19 and the four mounting parts 15 is made into a non-Taber connection is so that the buffer member 13 can be easily removed from the molding plate 9 when the concrete is lifted upward and molded. Based on consideration of.

In this way, the buffer member 14 attached to the molded plate 12 is fixed to its inner surface and does not fall inward, and the a! Even if concrete is poured, the I member 13 will not shift due to the impact.

In addition, the four mounting parts formed on the molded plates 9 and 12 15°1
6 and the mounting projections 19.20 formed on the buffer members 13.14 are not limited to the shapes shown in the illustrated embodiments. It is sufficient that the buffer member 13.14 can be attached and fixed to the molded plate 9.12 by fitting the concave and convex portions. Therefore, the number of grooves constituting the western attachment portions 15, 16 and the number of protrusions constituting the attachment convex portions 19,20 are also arbitrary.

Further, in the embodiment, the mounting recesses 16 are formed at both ends of the molded plate 12 so as to extend from one end to the other in the vertical direction; however, the mounting recesses 16 are not limited to this.
For example, they may be formed only at the four corners of the molded plate 13 or at arbitrary locations.

The left and right side molding plates 11 stand tiltably supported by shaft supports 10 provided on the side surfaces of the molding plate 9, and when the mold is opened, the left and right side molding plates 11 stand on both sides of the molding frame 1. It is supported in an inclined state by a stopper 21 attached to.

Next, a method of forming a concrete gutter cover using this formwork 1 will be explained.

First, by rotating the front and rear threaded rods 5 in one direction, the front and rear movable plates 6 are moved in parallel to the outside, respectively, and each molding frame 2 is opened. Then, oil is applied to the inside of each forming frame 2 to prevent concrete from adhering to the surface.

Then, on the four mounting parts 15 and 16 of the molded plate 9°12,
Soundproofing buffer members 13 and 14 are attached in advance.

To attach the buffer members 13, 14, proceed as follows.

That is, by using the gaps between the molding frames 2 created by opening the mold, the mounting recesses 15 formed in the molding plate 9 are
The buffer member 13 is horizontally fed. Then, the mounting convex portions 19 formed on the surface thereof are fitted into the four mounting portions 15 and fixed onto the molded plate 9.

Further, regarding the buffer member 14, the buffer member 14 is vertically applied to the mounting recess 16 formed in the molded plate 12. Then, the mounting protrusion 20 formed on the surface thereof is fitted into the mounting recess 16 and dropped downward to be mounted and fixed on the molded plate 12.

After the buffer members 13 and 14 are attached to each molding frame 2, the front and rear threaded rods 5 are again rotated in the other direction to tighten each molding frame 2 from the left and right sides to form a molding chamber. Then, reinforcing steel is inserted into this molding chamber and concrete is poured. The poured concrete is applied to the four parts 1 formed on the back side of the buffer members 13 and 14 to prevent peeling.
7.18, and is filled so as to include the gate 17.18 and bury a part of the buffer member 13.14. After that, the poured concrete is compacted using a vibrator or the like. After curing and hardening for a predetermined period of time, the mold is opened and the molded gutter cover is lifted upward, and the buffer members 13 and 14 are removed from the partition forming plates 9 and 12, and the concrete gutter 1c with the mounting member a is removed. Demolded. The demolded gutter cover C is as shown in Fig. 7,
Buffer members 13 and 14 are integrally fixed to both sides of the bottom part and above the side part in which a drainage notch is formed.

Next, FIGS. 8 to 11 show examples of partial modifications of the previously described embodiment. That is, the molded plate 12 shown in FIG.
forms a recess S1 having a width in which the buffer member 14 is just fitted and a depth shorter than its thickness, and these four parts S1
An example is shown in which four attachment parts 16 are formed inside. Further, in this example, the peeling prevention means formed on the back surface of the buffer member 14 is composed of a relatively large tapered recess.

However, the shape of the peeling prevention means formed on the back surface portion is not necessarily limited to a tapered recessed portion, and any shape of the four portions may have the same shape as long as the entrance is narrower.

FIG. 9 shows an example in which a peeling prevention means T is formed on the side surface of the buffer member 14. That is, in this example, the buffer member 14
By making both sides of the concrete tapered side surfaces narrower toward the surface, peeling from the concrete molded product is prevented. The same effect can be obtained even if a concave portion or a convex portion is formed on the side surface portion.

Further, FIG. 10 shows an example in which a tapered convex portion R whose tip widens out is formed on the back surface of the buffer member 14 as a peeling prevention means. As is clear from the above examples, the peeling preventing means may be formed on either the back surface or the side surface of the buffer member 14, and may be formed on four parts or on a convex part, and its shape and structure may be determined in a specific manner. but not limited to.

Furthermore, FIG. 11 shows an example of a structure in which the buffer member 14 can be placed in close contact with the surface of the molded plate 12 without leaving any gaps.

That is, in this example, both sides of the buffer member 14 have tapered side surfaces that widen on the surface side.

On the other hand, the molded plate 12 has a width that is just large enough to hold the buffer member 14, and a depth that is shorter than the thickness thereof, and has an entrance that is narrower from the inside so as to correspond to the tapered side surface of the buffer member 14. A tapered recess S2 is formed. A mounting recess 16 is formed within the four parts S2. In this example as well, a tapered convex portion R is formed as a peeling prevention means, but a tapered concave portion or other concave portion may be used.

The modified examples shown in FIGS. 8 to 11 are also applied to the buffer member 13 and the V-shaped plate 9 as they are.

Next, FIGS. 12 to 17 show other embodiments of the present invention. In the first embodiment, the concrete is cast in the length direction of the gutter cover, so to speak, by a vertical casting method, but in this embodiment, the concrete is cast in the width direction of the gutter cover, so to speak, by a horizontal casting method. This is an example.

That is, the molding frame shown in the figure is similar to the MS1 embodiment described above,
Each molding frame 2 is bow-tightened during concrete pouring, and after molding is completed, it is separated to open the mold, and a large number of concrete molded products can be demolded at the same time. Each molding frame 2 includes a bottom molding plate 22, left and right side molding plates 23, and a partition molding plate 24.

First, the bottom molding plate 22 and the partition molding plate 24 will be described. The former molds one side surface of the gutter lid, and the latter molds the surface and bottom portions of the gutter lid. However, unlike the first embodiment, the partition forming plate 24 in this embodiment functions as a forming plate for forming the surface portion of the gutter cover on the inner side, and as a forming plate for forming the bottom portion on the outer side.

Then, four mounting parts 26 to which the buffer member 25 is attached are formed on the outer surface thereof. The buffer member 25 basically has the same structure as the member 14 described in the first embodiment.

That is, a plurality of mounting protrusions 27 are formed on the front surface, and a plurality of tapered recesses 28 are formed on the back surface, which function as peeling prevention means. In the illustrated embodiment, each of the mounting convex portions 27 has a shape in which only the outer side surface is a sloped surface and the tip is widened. The reason why only one side surface is a sloped surface is based on the consideration that it can be easily removed from the molding plate 24 during demolding.

The attachment recess 26 extends in a direction perpendicular to the reed feeding direction on the outer surface of the molded plate 24, and has a corresponding shape into which the attachment convex portion 27 of the buffer member 25 just fits.

Also, one side molding plate 23, that is, the molding plate 23 that forms the side surface of the gutter cover with a notch for drainage, has a mounting recess ff! for attaching the buffer member 29. ! 30
is formed. The four mounting parts 30 are the mounting parts described above [! It has almost the same structure as the first part 26, and has the same structure as the molded plate 2.
3, and members 29 having substantially the same structure as the buffer member 25 can be attached.

The method of attaching the buffer members 25 and 29 is as follows.

First, the buffer member 25 is inserted into the upper and lower mounting portions 26 formed on the outer surface of the partition molded plate 24 from either the left or right direction. At this time, the attachment convex portions 27 formed on the surface of the buffer member 25 are fitted into the four attachment portions 26, and are inserted at the upper and lower portions so as to be slid as they are in the horizontal direction, that is, in a concave manner. Further, the buffer member 29 is fitted into the mounting recess 30 formed in one of the side molded plates 23 in the same manner as described above, and is attached by being pushed deep into the four parts 30.

When the installation of the buffer members 25 and 29 is completed, concrete is poured and demolded in the same manner as in the first embodiment described above, resulting in a gutter MCI as shown in Fig. 17.
can be obtained.

In the above first and second embodiments, an example was explained in which the present invention was applied to a screw-driven multi-cavity type concrete molding form, but the present invention can also be applied to a clamp-driven formwork. is clear. Further, the molding is not necessarily limited to molding a large number of molds, and in extreme cases, it is also possible to use a mold for molding a single mold.

Furthermore, the molding frame 2 described in the above fJSl and the second embodiment also forms an attachment recess 15 or 30 for attaching a buffer member to the bottom molding plate 9 or one of the side molding plates 23. However, the gutter cover does not necessarily have to be provided with a buffer member on its side surface. Therefore, the molding frame 2 is attached to the buffer member 14. It is sufficient to form a recess 16, 26 for attaching 25.

(Effects of the Invention) The present invention has the above configuration and has the following effects.

1) According to the molding method and molding frame described in illi items 1 and 2, the molding frame is stacked in the thickness direction of the gutter lid so that the surface and bottom parts of the gutter lid are molded in the vertical direction. concrete can be poured. Therefore, compared to the conventional flat forming method, the installation area of the mold for each molded product is smaller, and a large number of molded products can be efficiently manufactured even in a narrow workshop. In addition, the work of pouring concrete into the formwork becomes easy and requires less effort, and the number of parts to be finished with a trowel is reduced, so the molding work can be carried out by a small number of people.

Furthermore, since the soundproofing buffer member is attached to the molded plate by fitting the concave and convex portions into the molded plate, the buffer member can be reliably fixed in a fixed position when concrete is poured. Therefore, regardless of whether the poured concrete is of uniform quality or not, the buffer member can be attached to the concrete surface at a uniform depth.

Furthermore, since the thickness direction of the molded product is regulated by the molding plate, the surface and bottom parts can be reliably formed into horizontal planes, and furthermore, it is possible to eliminate errors in thickness dimensions, which improves quality. There is no variation.

2) In the molding frame according to claim 3, since the molding frames are formed in a series so as to overlap each other in the direction of the length of the molded product, a large number of molded products can be obtained at the same time by the standing casting method. Moreover, since one partition molding plate that partitions the molding chambers can also be used as a partition molding plate for adjacent molding frames, the overall mold structure can be kept low in cost.

3) The soundproofing buffer member according to claim 4 has a mounting convex portion on its surface. Therefore, it is possible to reliably attach and fix it to the attachment recess formed in the forming plate of the concrete forming frame by fitting the unevenness. In addition, since the buffer member is equipped with a means to prevent it from peeling off from the concrete molded product on its back or side surface, when it is removed from the mold, it remains attached to the concrete side, and together with the molded product, it is You can get off the board.
