Description

Euroform {EURO-FORM}

The present invention relates to a flow path form used in concrete curing work.

When constructing a concrete structure, a formwork is used that can maintain its shape for the duration of the hardening of the kneaded concrete. Then, after the concrete hardens, the formwork is removed.

The formwork can be provided in various shapes and materials depending on the type or height of the building to be built, but in the case of an apartment or large building, the formwork is manufactured using standardized EURO-FORM.

In general, the euroform is composed of a facing sheet facing concrete and a support frame supporting the facing sheet.

Conventionally, a plate material such as plywood made of wood has been used as a facing sheet. However, the wooden facing sheet has a short lifespan due to the influence of moisture in the concrete, and can be damaged during the regeneration process by removing sticky concrete debris (refer to Utility Model Registration No. 20-0337175). In addition, the facing sheet is fixed to the support frame by rivets (see Patent Registration No. 10-1254111), and the wooden facing sheet is often damaged in the process of removing the rivets to be removed from the support frame after use.

That is, in many processes, a wooden face sheet is often damaged, and in recent years, instead of this, a face sheet made of a synthetic resin material is often used.

However, as mentioned above, since the face sheet is fixed to the support frame by rivets, in the case of the face sheet made of synthetic resin, the fixing operation is difficult, and the face sheet itself may be broken. Therefore, the work cannot be done at the construction site, and it is sent to a recycling plant where rivet removal work, surface polishing work, and re-fixing work are performed. And because of this, it takes a lot of time to recycle Euroform, so its usability is poor.

An object of the present invention is to provide a technology capable of removing a facing sheet from a support frame or attaching it to a support frame without using a separate mechanical device for removing rivets.

The flow path form according to the first aspect of the present invention includes a face sheet in contact with concrete; And a support frame for supporting the facing sheet. Including, the support frame has a wh-shaped rim, the rims of the left and right ends of the support frame are provided with rail grooves open to each other in a direction facing each other so as to be moved while the facing sheet is inserted, The rear end of the rail groove is closed and the front end is open to the front, so that the face sheet is mounted to the support frame by moving the face sheet backward while the rear end of the face sheet is inserted into the front end of the rail groove. , By moving the facing sheet mounted on the supporting frame forward, the facing sheet is removed from the supporting frame.

The facing sheet has a thickness difference between the left and right ends and the remaining portions inserted into the rail groove, so that the upper surface of the remaining portion has the same height as the upper surface of the rims of the left and right ends.

Fixing protrusions protruding toward the rail groove are formed on the rims of the left and right ends, and fixing grooves into which the fixing protrusions can be inserted are formed in the facing sheet at positions corresponding to the fixing protrusions.

Fitting protrusions protruding toward the rail groove are formed on the edges of both ends of the left and right ends, and the fitting protrusion may elastically advance and retreat a portion in contact with the facing sheet.

The support frame is provided with a clasp for hooking the mounted face sheet, and the clasp may be elastically movable to enable an operation of attaching or removing the face sheet to the support frame.

A detachment preventing member that may be detachably mounted to the support frame and prevents detachment of the facing sheet when mounted; It further includes.

The face sheet has a pull-out groove on its lower surface for use in pulling out the face sheet when removing the face sheet from the support frame.

The front end of the rail groove is extended to enter the facing sheet, so that the edge at the front end of the support frame is inclined.

The flow path form according to the second aspect of the present invention includes a face sheet in contact with concrete; And a support frame for supporting the facing sheet. Including, the support frame has a wh-shaped rim, the face sheet may be disposed on the support frame, the support frame has a fitting protrusion formed, and the fitting protrusion may be inserted into the face sheet. A fitting groove is formed.

The fitting protrusion is cut so that the middle part has a certain width, the upper end is extended, the upper end of the fitting groove is extended, and when the fitting protrusion is inserted into or removed from the fitting groove, the fitting protrusion is opened. It can be loosened or elastically restored.

According to the present invention, there are the following effects.

First, it is possible to easily mount the face sheet to the support frame or remove the face sheet from the support frame using a simple tool such as a hammer or screwdriver without a separate mechanical device.

Second, the detachment operation for the facing sheet is easy, so that the detachment operation can be performed at the construction site, which increases the use rate of the support frame, thereby improving workability and reducing the cost of work.

Third, since rivets are not used for mounting of the facing sheet, damage by rivets required when mounting the facing sheet to the support frame does not occur, and the life of the facing sheet is prolonged.

<Overview of Euroform>

1 is a schematic perspective view of a flow path form 100 according to an embodiment of the present invention.

The flow path form 100 includes a face sheet 110 and a support frame 120.

The facing sheet 110 comes into contact with concrete, and is manufactured by mixing synthetic resin and glass fiber in a certain ratio. A drawing groove 111 is formed on the lower surface of the facing sheet 110. Here, the withdrawal groove 111 allows the operator to insert a finger or other tool to apply the drawing to the face sheet 110 when the face sheet 110 is removed from the support frame 120 in the future.

The support frame 120 supports the facing sheet 110. That is, the face sheet 110 may be detachably mounted on the support frame 120, and the mounted face sheet 110 is supported by the support frame 120.

The support frame 120 is provided with a rail groove (RG) in the rim (B) of both ends of the left and right as shown in FIG. The rail grooves RG at both ends of the left and right ends are formed to be open in a direction facing each other. The rail groove (RG) is formed to be long in the front-rear direction, so that the left and right ends of the facing sheet 110 are inserted and moved in the front-rear direction.

And, as shown in Figure 3, the rear end (RT) of the rail groove (RG) is closed, the front end (FT) is open to the front. Therefore, as shown in FIG. 4, the facing sheet 110 can be mounted on the support frame 120 by moving the facing sheet 110 to the rear while the rear end of the facing sheet 110 is inserted into the front end of the rail groove RG. In contrast, by moving the facing sheet 110 mounted on the support frame 120 forward, the facing sheet 110 may be removed from the support frame 120.

For reference, since the rear end of the rail groove RG is closed in the process of mounting the facing sheet 110 to the support frame 120, the facing sheet 110 is not excessively moved backward and can be properly mounted. have.

In addition, as shown in FIG. 5, the front end FT of the rail groove RG is preferably extended in an inclined shape so that the facing sheet 110 can be properly entered. That is, the upper and lower widths of the front end of the rail groove RG are wider than the upper and lower widths of the rest of the rail grooves RG. So, in the process of mounting the facing sheet 110 to the support frame 120, the rear end of the facing sheet 110 can be easily inserted into the front end of the rail groove RG.

Meanwhile, as shown in FIG. 6, when the face sheet 110 has a thickness difference between the left and right ends inserted into the rail groove RG and the remaining portions, when the face sheet 110 is coupled to the support frame 120 The upper surface of the rest of the area is designed to have the same height as the upper surface of the frame (B).

In the case of the Euroform 100 having a coupling structure between the face sheet 110 and the support frame 120 as described above, the face sheet to maintain a stable fitting state when the face sheet 110 is fitted to the support frame 120 There may be various types of fixing structures for fixing 110 to the support frame 120. Therefore, hereinafter, the fixing structure between the support frame 120 and the facing sheet 110 will be described.

<Several examples of fixed structures>

1. Fixing structure by fixing protrusion and fixing groove

As in the example of Figure 5, the frame (B) of the support frame (120) is formed with a fixing protrusion (122) protruding toward the rail groove (RG), and the facing sheet (110) corresponding to the fixing protrusion (122) A fixing groove 112 into which the fixing protrusion 122 can be inserted is formed in the position. So, when the facing sheet 110 is inserted into the rail groove RG, the fixing protrusion 122 is inserted into the fixing groove 112 so that the facing sheet 110 can be stably coupled to the support frame 120. do.

This fixing structure uses the fact that the rim (B) of the support frame 120 can be bent or restored by elasticity, and the facing sheet 110 is in the rail groove RG as referred to in the exaggerated view of FIG. 7. When fitted, the portion of the rim (B) with the fixing protrusion 122 is pushed to the left and right and is slightly bent, and then restored when the fixing protrusion 122 and the fixing groove 112 match.

In this example, the fixing protrusions 122 and the fixing grooves 112 may be provided in an appropriate number in a line that maintains relatively easy detachment and stable fixing of the facing sheet 110.

2. Fixing structure by fitting protrusion

As in the example of FIG. 8, a fixing structure that can press the facing sheet 110 is also considered because the fitting protrusion 123 protruding toward the rail groove RG is formed on the rim (B) of the support frame 120. It will be possible. In this example, the fitting protrusion 123 may be provided in a form capable of advancing and retreating itself, or may be provided to have a structure capable of being expanded and restored when the external pressure is removed after being compressed by external pressure. Likewise, the fitting protrusions 123 may be provided in an appropriate number in a line that maintains relatively easy detachment and stable fixation of the facing sheet 110.

3. Fixing structure by clasp

9 is provided with a clasp 124 on the support frame 120 so that the facing sheet 110 mounted and coupled to the support frame 120 can be hung. According to this example, the clasp 124 is designed to be elastically flowable so that the operation of attaching or removing the facing sheet 110 to the support frame 120 is possible.

4. Fixing structure by separation prevention member

This example has a separate separation prevention member.

As shown in FIG. 10, the separation preventing member 130 may be detachably mounted on the support frame 120, and when mounted, the separation of the facing sheet 110 may be prevented.

Separation prevention member 130 is provided in the form of a digut ('c') shape in which the front end is closed, and can be easily mounted on the support frame 120 with a tool such as a hammer, and the support frame 120 with a simple tool such as a screwdriver. ) Can be easily removed. That is, the operator in the field can easily mount or remove the facing sheet 110 to the support frame 120 using a simple tool.

The flow path form 100 having the above structure may be used as follows.

When the euroform 100 is separated from the hardened concrete structure, workers in the field remove the facing sheet 110 from the support frame 120 with a simple tool such as a hammer or a screwdriver. And the removed face sheet 110 is sent to the factory for surface polishing, and a new face sheet 110 prepared in advance is mounted on the support frame 120.

For reference, it is also possible to sufficiently consider that the above various fixing structures are omitted, and the facing sheet 110 is configured to be properly forcibly fitted into the rail groove RG.

<modification example>

Referring to FIG. 11, the rear end portion of the support frame 120 may also be provided in a form in which the rear end of the facing sheet 110 can be fitted in the form of a rail groove RG. And in response to this, the rear end portion of the facing sheet 110 is also provided to have a thickness difference. According to this modification, the rear end portion of the facing sheet 110 can be more securely fixed.

<Another example for Euroform>

12 shows a flow path form 200 according to another example of the present invention.

In the flow path form 200 of FIG. 12, a fitting protrusion 223 is formed in the support frame 220, and a fitting groove 213 into which the fitting protrusion 223 can be inserted is formed in the face sheet 210.

The fitting protrusion 223 is cut so that the middle portion has a certain width, and the upper end is extended. And the fitting groove 213 has an extended upper end.

Therefore, when the facing sheet 210 is pushed from the top to the bottom, the fitting protrusion 223 is folded and inserted into the fitting groove 213 as shown in FIG. 13, and then restored to its original state by elasticity, and the facing sheet as shown in FIG. 14 It is in a state of being fitted so as to prevent the arbitrary removal of the 210. Subsequently, the operator may remove the facing sheet 210 from the support frame 210 using a simple tool such as a screwdriver.

Similarly, the fitting protrusion 223 and the fitting groove 213 need only be provided in an appropriate number that can be easily detached with a simple tool such as a screwdriver while being able to properly maintain the fixing structure.
