Description

Connector for rebar prefabrication and rebar prefabrication structure using the same {Connector for pre-fabricating the reinforced bar and pre-fabricating structure using the same}

The present invention relates to a connector for reinforcing concrete reinforcement and a reinforcing bar assembly using the same. More specifically, the reinforcing wire assembly required when constructing a reinforcement concrete structure using steel pipes and fixing pins is easily and quickly selected. As well as to be able to assemble, the present invention relates to a rebar prefabricated connector and a rebar prefabricated structure using the same, which can ensure the safety of the entire reinforced concrete structure.

Reinforced concrete structures are structures manufactured using materials such as wood, stone, steel, reinforced concrete, aluminum and plastics, and are used in buildings, bridges, viaducts, retaining walls, tunnels, dams, waterways and towers. This refers to the general architectural style used in almost all buildings of modern society.

This reinforced concrete structure is the most rational and ideal because it combines the characteristics of concrete with high compressive strength but very low tensile strength and reinforcing steel bars that fill the concrete to compensate for the insufficient tensile strength of concrete. It is not an exaggeration to say that there are few fields that do not utilize reinforced concrete structures from all the large buildings representing the modern society to simple structures, because they are excellent enough to be evaluated as a combination.

However, reinforced concrete structures cannot function properly according to the original design purpose due to various factors, and also deteriorate durability, safety, and functionality.Although reinforced concrete structures are effectively used during the service life, they are always required to be fully functional. The safety of the structure should be reviewed, and in the event of aging or damage, repair and reinforcement should be secured.

Very serious problems can arise when neglecting or neglecting efforts to ensure the safety of reinforced concrete structures.

In other words, due to the result of ultra-high-rise, large-scale, and increased seismic consideration in the design of modern reinforced concrete structures, it is inevitable that the self weight increases and the cross-section of the members increases toward the bottom of the structure. In order to solve the economic and structural problems, many researches and developments on the production of high strength and high performance concrete have been conducted. Through this, it is possible to reduce the member cross-section of the structure through the production of high strength and high performance concrete. Some problems have been solved, but this does not guarantee the complete safety of reinforced concrete structures, and the problems of reinforced concrete structures, especially shear failures frequently occurring between slabs and columns, still exist. .

On the other hand, apart from the safety of the reinforced concrete structure described above, the shortening of the construction period (hereinafter referred to as 'air') in the production of reinforced concrete structures can be seen as a very important problem.

Air in the construction industry is an area where absolute competitiveness is given in terms of business feasibility and cost, and the more air, the better the quality is guaranteed, while the overhead of construction work is extended due to the prolonged overall business period. This is because the direct cost increases due to inflation, and these cost increase factors are burdened by the implementer and the consumer, and also may cause problems in presale due to the prolonged period of occupancy after sale.

However, if the air is too short, the safety problem of the reinforced concrete structure is raised once again. As a result, the problem of securing safety and shortening the air of the reinforced concrete structure is very difficult problem like chasing two rabbits at once. It can not be.

In addition, in the construction of reinforced concrete structures, securing a uniform coating thickness, maintaining a constant interval of reinforcing bars, and the request for improving the quality of the reinforced concrete structures through this, can be seen as an important matter to be considered along with the above-mentioned stability and shortening of air. have.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, in describing the present invention, descriptions of already known functions or configurations will be omitted to clarify the gist of the present invention.

Reinforcing rod assembly assembly 1 according to various embodiments of the present invention includes a steel pipe and a fixing pin and is the same below.

Figure 1a is a perspective view showing a state of the steel pipe used in the reinforcing wire assembly assembly 1 according to an embodiment of the present invention, Figure 1b is a front view of the steel pipe of Figure 1a.

1A and 1B, the steel pipe 100 includes a support plate 110 and both side plates 130 coupled at both ends of the support plate 110. Therefore, the steel pipe 100 according to the present embodiment has a 'c' shaped cross section as a whole, but is not necessarily limited thereto, and may have a 'U' shaped cross section as long as there is no problem in the upright of the steel pipe.

The support plate 110 is a plate-shaped member, and includes an upper seating groove 113 formed by cutting the upper center portion and a lower seating groove 115 formed symmetrically thereto.

The upper seating groove 113 and the lower seating groove 115 is a part for the insertion of the main reinforcing bar (3) used in the reinforcing rod assembly, it is also possible to selectively omit any one, if necessary, which is slab, column, wall It is a problem to be decided according to the safety strength required in the construction of the lamp. In other words, in order to manufacture the reinforcement line assembly prior to the construction of the reinforced concrete structure according to the present embodiment, the burden load for stable support of the structure must be determined in advance, and accordingly, the upper seating groove 113 or the lower seating groove It is also possible to omit 115. However, in the general case, since the main reinforcing bar 3 will be inserted into both the upper seating groove 113 and the lower seating groove 115, hereinafter, the upper seating groove 113 and the lower seating groove 115 on the upper and lower sides of the support plate 110, respectively. The present embodiment will be described on the assumption that) is formed symmetrically.

The upper seating groove 113 has a 'U' shape and is formed with a sufficient depth. That is, since the main reinforcing bar 3 is inserted into the upper seating groove 113 as described below, the main reinforcing bar 3 is fixed by the fixing pin 300, and thus the fixing pin 300 is inserted. It is preferable to determine the depth of the upper seating groove 113 in consideration of this, the breakage of the upper side of the upper pin hole 131 and the adjacent steel pipe 100 does not occur.

Referring to Figure 1c, the upper seating groove 113 may be formed in the round bend at both ends of the support plate 110 is inserted into the main reinforcing bar 3, which is for convenience of the insertion process.

That is, if the starting point of the upper seating groove 113 is formed at a right angle with the upper end of the support plate 110, it may be difficult to facilitate the smooth insertion of the cast reinforcing bar (3), the above-described bending serves to prevent this.

In addition, the upper seating groove 113 may include a predetermined inclination (the length of b is longer than a) formed in the longitudinal direction of the steel pipe 100 in accordance with the progress of the insertion process of the cast steel (3). According to such inclination, without having to insert the main reinforcement (3) by applying excessive force, the main reinforcement (3) to the bottom of the upper seating groove 113 only by placing the main reinforcement (3) in the upper seating groove 113 It slips.

In the case of the lower seating groove 115, there are differences only in terms of the position, and other details are the same as the upper seating groove 113, and thus, detailed description thereof will be omitted.

Both side plates 130 extend from both ends of the support plate 110 and are formed symmetrically, and include upper and lower pin holes 131 and lower pin holes 133, which are formed symmetrically on the upper and lower sides, respectively.

The upper pin hole 131 includes a semicircular shape as shown as a portion to be an insertion passage of the fixing pin 300. The matters relating to the shape and size of the upper pin hole 131 is related to the function of the fixing pin 300, so the detailed description will be described later. In the case of the lower pin hole 133, only matters regarding the forming position are different. Since the same as the upper pin hole 131, a detailed description thereof will be omitted.

2, the steel pipe 100 according to another embodiment of the present invention further includes at least one protrusion 150 formed to protrude from at least one surface of the support plate 110 and both side plates 130. do.

The protrusion 150 is a configuration provided to firmly couple the concrete and the steel pipe 100 when using the reinforcing wire assembly (1) is not limited in position, shape, number.

Since the contact area of the steel pipe 100 coupled and hardened together with the concrete poured during the construction of the reinforced concrete structure is enlarged through the protrusion 150, the reinforced concrete structure when the connector 1 for reinforcing the wire assembly according to the present embodiment is utilized. The effect of improving the overall stability can be obtained. Other supporting plate 110, the upper seating groove 113, lower seating groove 115, both side plate 130, the upper pin hole 131 and the lower pin hole 133, the matters shown in Figure 1a and 1b Same as the example.

Referring to FIG. 3A, the fixing pin 300 includes a semicircular shape, and utilizes a tapered pin having a predetermined inclination when progressing from one end to the other end. However, as long as it can perform the function of the fixing pin 300, the shape may be any 'U' shaped other, the upper side and the upper pin hole 131 of the main reinforcement (3) inserted into the upper seating groove 113 If the lower side is formed to overlap a certain portion, it is also possible to use a general parallel pin as the fixing pin 300. (In the case of the taper pin to be described later, since the reinforcing bar (3) is forcibly moved to the lower side when the parallel pin is inserted) The same effect can be obtained.)

In addition, it is not necessary to form an inclination on both the upper and lower sides of the fixing pin 300, and the fixing pin 300 is formed in the upper side in parallel to include the inclination only on the lower side of the fixing pin 300 in direct contact with the cast iron (3). It is also possible, and this will be explained in the method of fixing the cast bar 3, which will be described later. (In the case of the fixing pins 300, 301 and 302 shown in Figs. 3A to 3D, the insertion of the fixing pins 300, 301 and 302 is started from the rear of the drawing. )

Referring to FIG. 3B, the fixing pin 300 may further include a seating jaw 310 having one end stepped.

Seating jaw 310 is a configuration that can be added to facilitate the insertion process of the fixing pin 300, its function will be described in the fixing method of the cast iron (3) to be described later.

Referring to Figure 3c, the fixing pin 301 may utilize a general square pin tapered in the longitudinal direction and the other details are the same as the fixing pin 300 shown in Figure 3a and a detailed description thereof will be omitted.

Referring to FIG. 3D, the fixing pin 302 may be a circular pin tapered in the longitudinal direction. However, since the contact area with the main reinforcing bar (3) is reduced in the case of a circular pin, there is a possibility that a sliding phenomenon that the fixing pin 302 is separated from the pinhole by an external impact, etc., may occur. It is preferable to add the fixing protrusion 320.

The fixing protrusion 320 may include at least one protruding one end of the fixing pin 302 which becomes the initial insertion site when the fixing pin 302 is inserted. For example, when the fixing protrusion 320 includes two fixing protrusions 320, the fixing protrusion 320 is fixed. The spacing between the protrusions 320 is slightly larger than the thickness of both side plates 130, thereby reducing the movable range of the fixing pin 302.

However, considering that the main role of the fixing pins (300,301,302) is to securely fixed the inserted main steel bars (3) by increasing the cross-sectional area in contact with the main steel bars (3), the fixing pins (300,301,302) is a semi-circular taper rather than using a circular pin Preference is given to using pins or square tapered pins.

In addition, in the case of using the square tapered pin according to Figure 3c as a fixing pin 301 and the circular pin according to Figure 3d as a fixing pin 302, the upper pin hole 131 and the lower pin hole of the steel pipe 100 The shape of the 133 should be made in a shape corresponding to the shape of the fixing pins (301, 302).

Referring to FIG. 3E, the fixing pin 303 may be a tapered pin having a 'c' shaped cross section and tapered in the longitudinal direction. In this case, the upper pin hole 131 and the lower pin hole 133 may have a shape of the fixing pin 303. Correspondingly, it should be formed with 'c' shaped cross section or rectangular cross section. When the upper pin hole 131 and the lower pin hole 133 is formed with a 'c'-shaped cross section, it may be difficult to insert the fixing pin 303, but the effect of preventing the fixing pin 303 from being separated may be achieved. In the case of a rectangular cross section, since the convenience of the insertion process of the fixing pin 303 can be facilitated, the shapes of the upper pin hole 131 and the lower pin hole 133 are determined in consideration of this comprehensively.

Referring to FIG. 4, the main reinforcing bar 3 is inserted into the upper seating groove 113 and the lower seating groove 115, and then the fixed pin 300 is fixed thereto.

That is, after the main reinforcing bar 3 is inserted into the upper seating groove 113 and the lower seating groove 115, the fixing pin 300 is roughly positioned along the upper pin hole 131 and the lower pin hole 133, and the hammer and the like. It is subjected to a process of forcibly inserting it by using the hitting tool, and as shown in FIG. 3b, when the mounting jaw 310 is included in the fixing pin 300, the fixing pin penetrates through both side plates 130 ( 300 can be located roughly, easily.

As such, after the fixing pin 300 is roughly positioned in the upper pin hole 131, the fixing pin 300 is forcibly inserted into the fixing pin 300. The fixing pin 300 is formed below the fixing pin 300 in close contact with the cast iron 3. Due to the characteristics of the inclined surface, the main reinforcement (3) is gradually in close contact with the upper seating groove 113 and the lower seating groove 115, and is firmly fixed so that it can no longer move when the insertion process is terminated.

Therefore, the degree of inclination formed on the fixing pin 300 should be formed to the extent that the fixing pin 300 itself is not damaged by excessive force while being able to firmly fix the main reinforcing bar 3, which is before the manufacturing of the fixing pin 300. It can be seen as a problem to be decided.

In addition, unlike a circular reinforcing bar, the bar is included in the rebar itself bar semi-circular fixing pin 300 in the case of a semi-circular inner diameter, in the case of a square fixing pin 301, the length of the bottom of the square cross-section, circular pin ( In the case of the 302, the fixing pins 300, 301 and 302 should be designed so that the part in contact with the main reinforcing bar 3 is not interfered by the nodes (see Fig. 4).

Now, the following will be described in detail with respect to the rebar prefabricated structure using the reinforcing bar assembly (1) on the basis of the understanding of the matter relating to the reinforcing bar assembly (1) described above. Hereinafter, the rebar prefabricated structure means a prefabricated structure (structure completed using a pair or two pairs of steel pipes) according to various embodiments of the present invention, and the rebar preassembly utilizes the rebar prefabricated structure. By means of the completed reinforcing bar binding structure (including the main reinforcing bar (3) and the fixing pin 300).

Referring to FIG. 5A, the steel pipe used in the rebar prefabricated structure using the rebar prefabricated connector 1 is based on the steel pipe 100 shown in FIG. 1A, and the center or both side plates 130 of the support plate 110. ) Further includes at least one first assembly hole 171 formed near the center. Of course, it is also possible to use the steel pipe 100 shown in FIG. 2, and it is noted that all the matters related to the salping steel pipe are applicable to the present reinforced steel assembly structure as it is.

The first assembly hole 171 is a portion that serves as a passage of the assembly member 7 for interconnecting the two steel pipes 100 and is formed near the center of the support plate 110 or both side plates 130.

As shown in FIG. 5B, the assembly member 7 is preferably made of reinforcing bars or other rigid materials so that deformation does not occur. This is achieved by maintaining a constant interval between the mutually bound steel pipes 100. This is to secure the coating thickness.

Referring to FIG. 5B, the rebar prefabricated structure according to the exemplary embodiment of the present invention places a pair of steel pipes 100 at an appropriate position, and then inserts the assembly member 7 into the first assembly hole 171. The steel pipe 100 is completed by securing a constant distance between each other. 5b, it can be seen that the first assembly hole 171 is formed in the center of the support plate 110.

The black part of the figure shows a welding part. After inserting the assembly member 7 into the first assembly hole 171, the members are firmly fixed to each other by welding.

In other words, if the separation distance between the steel pipes 100 is not sufficiently secured due to the characteristics of the reinforcing steel prefabricated structure which is located inside the reinforced concrete structure and is embedded in the concrete, there may be a problem in that it does not properly maintain the reinforcing coating thickness. In order to use a fixed method such as welding.

The rebar prefabricated structure according to the present embodiment is completed by a pair of steel pipes 100 connected by the assembly member 7, but in the case of the rebar prefabricated structure actually required when constructing the reinforcement concrete structure, the main reinforcement 3 is It must be included and fixed.

In other words, if you want to build reinforced concrete structures such as walls (walls, slabs, beams, columns, etc.), according to the present embodiment, the rebar prefabricated structure is prepared in advance and transported to the construction site, the upper seating groove 113 And the main reinforcing bar (3) is inserted along the lower seating groove 115, and should be arranged in the structure (wall, slab, etc.) to be built in a fixed state by the fixing pin 300, which is two pairs of steel pipe (100) The same applies to rebar prefabricated structures that are preassembled using).

Referring to FIG. 5C, two first assembling holes 171 are formed in both side plates 130 of the steel pipe 100, and each of the reinforcing wire assemblies in which the assembling members 7 are inserted and then fixed thereto by welding. You can see how it looks. It is also possible to manufacture the rebar liner assembly as shown in Fig. 5c in consideration of the burden of the structure to be constructed, in particular, in the case of column construction, when the rebar liner assembly is produced on the ground, lifted by a crane, and then upright, Given that the load on the rebar prefabricated structure is very large, it is desirable to utilize the embodiment shown in FIG. 5C. Of course, if the load is greater, it is conceivable to utilize three assembly members 7 and it will be apparent to those skilled in the art that it is also possible to utilize more assembly members 7.

Referring to FIG. 5D, using three steel pipes 100, two first assembling holes 171 are formed in both side plates 130 of the steel pipe 100, and then, assembling members 7 are inserted. It can be seen that the shape of the reinforcing steel bar assembly fixed by welding, similar to the reinforcing steel bar assembly shown in Figure 5c in the case of this embodiment can be seen that the high utilization of the pillar construction. That is, in the case of a pillar having a large width, it may be more preferable in terms of strength to position the reinforcing line assembly shown in FIG. 5D than to place several rebar line assemblies shown in FIG. 5C in the horizontal direction.

In both the case of Figure 5c and 5d, two or three steel pipes 100 are positioned in the horizontal direction and then bound to each other through the assembly member 7 to complete the reinforced prefabricated structure, such a reinforced prefabricated structure The rebar pre-assembly is completed by placing the main reinforcing bars 3 after placing several pieces back and forth (in a direction perpendicular to the ground). Of course, the fixing pins (300, 301, 302, 303) are inserted in the direction crossing the main reinforcement (3).

In addition, the position of the first assembly hole 171 will be formed in the vicinity of the center of the support plate 110 in the case of Figure 5b, but in the vicinity of the center of both side plates 130 as shown in Figures 5c and 5d Will be formed.

Referring to Figure 6a, it can be seen the appearance of the steel pipe 100 used in the reinforcement line assembly structure is completed using two pairs of steel pipe (100).

In addition to the first assembly hole 171, the steel pipe 100 illustrated in FIG. 6A further includes at least one second assembly hole 172 formed through the center of the support plate or both side plates 130.

Like the first assembly hole 171, the second assembly hole 172 plays a role of a passage through which the assembly member 7 is inserted, and a method of binding the assembly member 7 and the second assembly hole 172. The matters regarding the same are the same as the case where only the first assembling hole 171 is formed.

Referring to Figure 6b, it can be seen the shape of the rebar pre-assembly structure and the reinforcement line assembly completed using the two pairs of steel pipe 100, the assembly sequence is similar to the case of Figure 5b first the steel pipe of Figure 6a ( 100) by placing the four in the appropriate position, and inserting the assembly member (7) in the first assembly hole 171 and the second assembly hole 172 to bind the steel pipe (100) to each other to build the reinforcement line assembly structure. After completing and carrying it, inserting the main reinforcing bar (3) along the upper seating groove 113 and the lower seating groove (115) and using the fixing pin 300 to bind the main reinforcing bar (3) to complete the reinforcement line assembly You will follow the method.

However, this order is not strictly determined, and the priority may be changed according to convenience, so that the reinforcing bar 3 is firmly fixed by the fixing pin 300, and the separation distance between the steel pipes 100 may be sufficiently secured. As far as possible, it is considered that the order falls within the scope of the present invention.

Referring to FIG. 7, it can be seen that the reinforcing member 5 is bound by reinforcing the reinforced wire assembly shown in FIG. 6B.

The reinforcing member 5 is fixed to the rebar line assembly by binding the assembly members 7 to each other by welding or the like. The purpose of the reinforcing member 5 is to use the connecting line 1 for the reinforcing line assembly. The finished rebar prefabricated structure is intended to prevent twisting or deformation according to the pouring of concrete, the material is not necessarily limited to the reinforcing bar may be variously configured. However, if the material with low adhesion to concrete is selected, the safety of the reinforced concrete structure itself may be lowered and should be selected in consideration of this.

In addition, the position and shape of the reinforcing member 5 is not limited, and when the material of the reinforcing member 5 is made of reinforcing bars, as shown in FIG. 7, the assembly members 7 cross each other in an 'X' shape. It is possible to follow the method of squeezing and fixing by welding, and may be arranged in parallel between the other assembly members 7 and fixed by welding. In addition, in the case of using the two assembly members 7 as shown in Figure 5c, it is also possible to fix the lower assembly member (7) between the upper assembly member 7 and the mutually by welding, in this case than It has the advantage of maintaining improved bonding strength.

Referring to FIG. 8, when fabricating a rebar liner assembly required for building a wall, it may be seen that a state using the rebar liner assembly illustrated in FIG. 6B is used.

First, as shown in FIG. 6b, after the four steel pipes 100 are fastened to each other through the assembly member 7, the rebar prefabricated structure is prepared, and then transported and disposed at an appropriate position on the wall surface to be constructed. The main reinforcing bar 3 is inserted along the upper seating grooves 113 and the lower seating grooves 115 of the steel pipes 100, and fixed using the fixing pin 300.

In addition, when the reinforcing rod assembly to serve as a base frame is completed, as shown in the figure, the main reinforcement (3) reinforces the main reinforcing bars (3) for supplementary binding in the horizontal and longitudinal direction between each other, and connecting members 9 By binding each other through), the fabrication of the rebar prefabrication is completed. The connecting member 9 is generally used a tie wire (for example, 'wire'). Preferably all the cast steels 3 shown are arranged at equal intervals from one another.

Of course, in addition to the method of manufacturing only the rebar prefabricated structure in advance and then carrying it back to complete the rebar preassembly using the main reinforcement (3) and the fixing pins (300), the entire reinforcement pre-arranged to the main reinforcement (3) It is possible to assemble and follow the proper method considering the weight and cost.

After arranging the prefabricated reinforcing wire assembly according to the present invention on the wall surface, if the concrete is poured only, the entire process is completed, so that the effect of air shortening can be achieved, and in the structures of slabs, columns, beams, etc. It can be seen that all of the above is applicable.

While specific embodiments of the invention have been described and illustrated above, it is to be understood that the invention is not limited to the described embodiments, and that various modifications and changes can be made without departing from the spirit and scope of the invention. It is self-evident to those who have. Therefore, such modifications or variations are not to be understood individually from the technical spirit or point of view of the present invention, the modified embodiments will belong to the claims of the present invention.
