Description
Technical Field
[0001] The present invention relates to a separator fixing device for a formwork. More specifically, it can easily compare and identify the height of a separator provided with nuts inserted into a set scale groove formed in the front part of a body and a seating groove of the body, quickly and clearly determine the state of the nuts seated in the seating groove, and take corresponding measures. Therefore, it can solve various problems that may occur in a conventional separator fixing device where the nuts cannot be inserted to the bottom of the seating groove of the body, and ensure excellent durability of the constructed concrete building. The present invention relates to a separator fixing device for a formwork.
Background Art
[0002] Generally, when constructing reinforced concrete structures such as columns, beams, and wall bodies in various buildings, after arranging steel bars, a formwork is formed, and concrete is poured into the formwork for construction.
[0003] Here, the load of the concrete is transmitted to the formwork and the formwork is pushed out. If the formwork is pushed out, the structure will not be constructed as designed, and there is a risk of shoddy work. Therefore, in order to prevent this and strengthen the building to withstand external forces such as earthquakes and typhoons, a separator is installed to keep the interval of the formwork constant. Here, after installing the separator fixing device on the formwork, both ends of the separator are coupled to the separator fixing device, and concrete is poured to embed the separator together in the concrete, so that the formwork is not pushed out even by pouring the concrete, and a certain width is maintained as designed in the architectural design, and a concrete structure that can withstand the stress generated outside by an earthquake or the like is constructed.
[0004] The conventional separator fixing device is used to fix a separator that is used to keep the intervals of concrete formworks constant when building concrete structures such as columns, beams, and wall bodies of various buildings. Inside, a seating groove is formed where a square nut provided on the end of the separator is seated. The seating groove has an open upper part, and both ends include a body that widens in a "V" shape and a fixing pin formed on the rear surface of the body to bind and fix the body inside the formwork.
[0005] However, in the conventional separator fixing device, it frequently occurs that the nut cannot be inserted to the bottom of the seating groove because the nut tilts during the process of inserting and seating the nut of the separator into the seating groove of the body. In such a case, since the separator cannot be firmly fixed by the stopper formed in the seating groove, there is a problem that the separator frequently detaches due to the upward external force caused by the concrete driven into the formwork.
Summary of the Invention
Problems to be Solved by the Invention
[0006] The present invention is proposed to solve various problems as described above. The purpose is to easily compare and identify the height of the separator formed with a set scale groove formed in the front part of the body and a nut inserted into the seating groove of the body, and quickly and clearly determine and handle the state of the nut seated in the seating groove. Therefore, it solves various problems that occur when the nut cannot be inserted to the bottom of the seating groove of the body in the conventional separator fixing device, and provides a separator fixing device for a formwork that can ensure excellent durability of the constructed concrete building.
[0007] In addition, due to the structure in which the locking protrusions formed on both sides of the seating groove of the body are inserted and fastened into the locking grooves formed in the nut, the separation of the nut seated on the body can be more stably prevented. Therefore, the problems that may occur due to the separation of the separator by the concrete driven into the conventional separator fixing device are solved, and a separator fixing device for a formwork that can ensure excellent durability of the constructed concrete building is provided.
Means for Solving the Problems
[0008] The separator fixing device for a formwork according to the present invention is for fixing a separator used to maintain a constant interval between concrete formworks when constructing concrete structures such as columns, beams, and wall bodies of various buildings. Inside, a seating groove is formed where a square nut provided on the end of the separator is seated. The seating groove includes a body with an open upper part and both ends spreading in a "V" shape, and a fixing pin formed on the rear surface of the body to bind and fix the body inside the formwork. The separator fixing device is characterized by including a setting scale groove formed horizontally and long on the front surface of the body to set the height of the upper surface of the separator fastened to the nut seated in the seating groove of the body.
[0009] Further, the setting scale groove is formed in an "∠" shape including a horizontal plane and an inclined plane formed obliquely upward from the end of the horizontal plane.
[0010] In addition, locking protrusions protruding inside the seating groove by punching are formed on both sides of the seating groove of the body, and locking grooves into which the locking protrusions are inserted are formed at the centers of the left and right side surfaces and the upper and lower side surfaces of the nut.
[0011] Furthermore, it is characterized by further including an identification band of a predetermined hue laminated on the horizontal plane of the setting scale groove to induce easy identification of the setting scale groove.
[0012] Further, inside the seating groove of the body, there is an inner circumferential insertion color band which is horizontally positioned at a position parallel to the set scale groove and has a hue that is easy to identify in order to confirm that the nut is seated in the normal position below the seating groove. It is characterized by further including this.
Advantages of the Invention
[0013] According to the separator fixing device for a formwork according to the present invention, it is possible to simply compare and identify the set scale groove formed at the front part of the body and the height of the separator formed by the nut inserted into the seating groove of the body, and quickly and clearly determine and deal with the state of the nut seated in the seating groove. Therefore, various problems that occur when the nut cannot be inserted to the bottom of the seating groove of the body in the conventional separator fixing device are solved, and it is possible to ensure excellent durability of the concrete building to be constructed.
[0014] Also, due to the structure in which the locking protrusions formed on both sides of the seating groove of the body are inserted into the locking grooves formed on the nut and fastened, it is possible to more stably prevent the nut seated on the body from detaching. Therefore, problems that may occur when the separator detaches due to the concrete driven in the conventional separator fixing device are solved, and it is possible to ensure excellent durability of the concrete building to be constructed.

Embodiment for Carrying out the Invention
[0016] The present invention is for fixing a separator used to keep the intervals of concrete formworks constant when building concrete structures such as columns, beams, and wall bodies of various buildings. Inside, there is a seating groove where a square nut formed on the end of the separator is seated. The seating groove is open at the top, and both ends include a body that spreads in a "V" shape, and a fixing pin formed on the rear surface of the body to bind and fix the body inside the formwork. It is a separator fixing device,
[0017] It relates to a separator fixing device for a building formwork, characterized by including a setting scale groove that is horizontally and long formed on the front surface of the body and sets the height of the upper surface of the separator fastened to the nut seated in the seating groove of the body.
[0018] The separator fixing device of the formwork according to a preferred embodiment of the present invention will be described in detail based on the accompanying drawings. Detailed techniques regarding known functions and configurations that may unnecessarily obscure the gist of the present invention will be omitted.
[0019] Figs. 1 to 6 are diagrams showing the separator fixing device of the formwork according to an embodiment of the present invention. Fig. 1 is a perspective view of the separator fixing device for a building formwork according to an embodiment of the present invention, Fig. 2 is a cross-sectional view taken along line A - A of the separator fixing device for the building formwork shown in Fig. 1, and Figs. 3 to 6 are usage state diagrams of the separator fixing device for the building formwork shown in Fig. 1.
[0020] As shown in the drawings, the separator fixing device 100 of the formwork according to the embodiment of the present invention is used to fix a separator 2 for maintaining a constant interval between concrete formworks 1 when building concrete structures such as columns, beams, and wall bodies of various buildings. Inside, a seating groove 4a is formed where a square nut 3 formed on the end of the separator 2 is seated. The seating groove has an open upper part, and a body 4 whose both ends expand in a "V" shape, and a fixing pin 5 formed on the rear surface of the body 4 for binding and fixing the body 4 inside the formwork 1. The separator fixing device includes:
[0021] As shown in FIGS. 1 and 2, on the front surface of the body 4, a setting scale groove 10 is formed that is horizontally long and sets the height of the upper surface of the separator 2 fastened to the nut 3 seated in the seating groove 4a of the body 4.
[0022] The nut 3 usually provided on the separator 2 is inserted and arranged in the seating groove 4a of the body 4. Even when the seating groove 4a is located in front of or behind the position of the nut 3, the nut 3 is fastened to a screw portion 2a formed at the end of the separator 2 so that the nut 3 can be easily inserted into the seating groove 4a by being transferred forward or backward along the screw portion 2a and positioned.
[0023] Due to the characteristics of the nut 3 as described above, when the nut 3 rotates and tilts like a "◇" shape for reasons such as the nut 3 coming into contact with the seating groove 4a during the process of an operator inserting and seating the nut 3 of the separator 2 into the seating groove 4a of the body 4, the width (W) of the nut 3 often becomes larger and it cannot be inserted to the bottom of the seating groove 4a.
[0024] If the operator finds that the nut 3 has not been inserted to the bottom of the seating groove 4a, the nut 3 can be correctly positioned and inserted to the bottom of the seating groove 4a. However, in a complex and busy work site, it is rather difficult to check the accurate insertion (entry) of the nut 3 one by one. If the nut 3 is not inserted to the bottom of the seating groove 4a in this way, the position of the separator 2 will be slightly higher. In such a case, in the process of narrowing the widened seating groove 4a, the stopper 4b formed in the seating groove 4a cannot support the upper part of the separator 2, so there is a risk that the separator 2 may be disengaged by the external force of the concrete driven into the formwork 1.
[0025] The separator fixing device 100 of the formwork of the present invention can clearly and easily identify the height of the separator 2 fastened to the nut 3 inserted and seated in the seating groove 4a of the body 4 by the set scale groove 10. As shown in FIG. 3, as an example, when the height of the upper surface of the separator 2 is formed higher than the set scale groove 10, the nut 3 cannot be inserted to the bottom of the seating groove 4a and the height of the separator 2 is in a high position, so the nut 3 must be inserted again. As shown in FIG. 4, if the height of the set scale groove 10 is the same as the height of the upper surface of the separator 2, the nut 3 is accurately inserted to the bottom of the seating groove 4a.
[0026] Therefore, the operator can very easily recognize the insertion state of the nut 3 according to the height of the separator 2 that is simply compared with the set scale groove 10.
[0027] Also, as shown in FIGS. 1 and 2, the set scale groove 10 is composed of a horizontal plane 11 and an inclined plane 12 formed obliquely upward from the end of the horizontal plane 11, and is formed in an "∠" shape.
[0028] That is, as shown in FIGS. 3 and 4, due to the characteristic that the operator works at a position where the line of sight slightly looks down at the body 4, it is preferable to form it in the shape of "∠" as described above so that the set scale groove 10 formed in the body 4 can be clearly identified without being blocked.
[0029] Furthermore, due to the characteristic that the body 4 itself is formed to be slightly smaller, the set scale groove 10 formed in the body 4 is also formed to be slightly smaller. Therefore, a groove is formed in the above-described form to induce clear identification of the set scale groove 10.
[0030] Also, as shown in FIGS. 1 and 2, it further includes an identification band 30 of a predetermined hue that is laminated on the horizontal plane 11 of the set scale groove 10 to induce easy identification of the set scale groove 10.
[0031] That is, as shown in FIGS. 3 and 4, the operator can be induced to more clearly identify the set scale groove 10 by the identification band 30 having a distinct hue, so that convenient and efficient use of the separator fixing device 100 of the formwork of the present invention can be induced.
[0032] On the other hand, as shown in FIGS. 1 and 2, locking protrusions 21 that protrude inside the seating groove 4a by punching are formed on both sides of the seating groove 4a of the body 4, and locking grooves 22 into which the locking protrusions 21 are inserted are formed at the centers of the left and right side surfaces and the upper and lower side surfaces of the nut 3.
[0033] That is, as shown in FIG. 3, if the seating groove 4a in which the nut 3 is completely inserted and seated in the seating groove 4a of the body 4 is narrowed, the locking protrusions 21 formed in the seating groove 4a are naturally inserted into the locking grooves 22 of the nut 3, so that the separator 2 is very firmly bound and fixed to the body 4 together with the nut 3.
[0034] Therefore, as shown in FIG. 6, it is possible to very stably prevent the separation of the separator 2 due to the external force of the concrete driven into the formwork 1.
[0035] The separator fixing device 100 of the formwork of the present invention having the above configuration can easily compare and identify the height of the set scale groove 10 formed at the front of the body 4 and the height of the separator 2 provided with the nut 3 inserted into the seating groove 4a of the body 4, and can quickly and clearly determine and handle the state of the nut 3 seated in the seating groove 4a. Therefore, by solving various problems that occur when the nut cannot be inserted to the bottom of the seating groove of the body in the conventional separator fixing device, there is an effect that excellent durability of the constructed concrete building can be ensured.
[0036] Also, due to the structure in which the locking protrusions 21 formed on both sides of the seating groove 4a of the body 4 are inserted and bound to the locking grooves 22 formed on the nut 3, the separation of the nut 3 seated on the body 4 can be more stably prevented. Therefore, it solves the problems that may occur when the separator is separated by the concrete driven in the conventional separator fixing device, and there is an effect that excellent durability of the constructed concrete building can be ensured.
[0037] The separator fixing device 100 of the formwork according to an embodiment of the present invention having the above configuration is used as follows.
[0038] First, as shown in FIG. 3, in order to install the separator 2 on the separator fixing device 100 of the formwork of the present invention fixedly installed on the formwork 1, the operator inserts the nut 3 into the seating groove 4a of the body 4 and seats it. Here, the height of the set scale groove 10 of the body 4 is compared and identified with the height of the separator 2 provided with the nut 3 inserted into the seating groove 4a. If the separator 2 is formed higher than the set scale groove 10, it is recognized that the nut 3 is not inserted to the bottom of the seating groove 4a.
[0039] Then, as shown in FIG. 4, the operator correctly aligns the position of the nut 3 and inserts and arranges it at the bottom of the seating groove 4a. In this way, when the nut 3 is inserted to the bottom of the seating groove 4a, the set scale groove 10 and the separator 2 are positioned on the same line, so it is possible to easily recognize that the nut 3 has been completely inserted to the bottom of the seating groove 4a.
[0040] After that, as shown in FIG. 5, if the seating groove 4a of the body 4 is narrowed through a jig device (not shown), the locking protrusion 21 formed in the seating groove 4a is naturally inserted into the locking groove 22 of the body 4 and firmly bound to the nut 3, thereby stably fixing the separator 2 connected to the nut 3.
[0041] Here, since the nut 3 is inserted and fixed to the bottom of the seating groove 4a, it goes without saying that the stopper 4b formed in the seating groove 4a to be narrowed also firmly supports and fixes the separator 2.
[0042] After that, as shown in FIG. 6, since the lifting and detachment of the separator 2 are stably prevented by the external force of the concrete driven into the formwork 1, it goes without saying that excellent seismic performance of the columns, beams, and wall bodies of the building to be constructed can be ensured.
[0043] In addition, the separator fixing device 100 for the formwork according to the present invention further includes an inner circumferential insertion ribbon 40.
[0044] The inner circumferential insertion ribbon 40 is provided inside the seating groove 4a of the body 4, is horizontally positioned at a position parallel to the set scale groove 10, and has a hue that is easy to identify in order to confirm that the nut 3 is seated in the normal position below the seating groove 4a.
[0045] Therefore, the inner circumferential insertion ribbon 40 cannot be seen before the nut 3 is completely inserted, but the inner circumferential insertion ribbon 40 can be surely seen from the outside when the nut 3 is completely inserted. Therefore, it is possible to easily recognize from the outside that the nut 3 has been completely inserted.
[0046] The present invention has been described based on the embodiments shown in the accompanying drawings, which are exemplary and not limited to the above-described embodiments. Those having ordinary knowledge in the art will be able to understand that various modifications and equivalent embodiments will be possible hereafter. Needless to say, modifications by those skilled in the art are possible within the scope that does not impair the idea of the present invention. Therefore, the scope of rights claimed in the present invention is not determined within the scope of the detailed description, but is limited by the claims described later and their technical idea.
