The present invention relates to a V-shaped tie hoop assembly, and more particularly, to a V-shaped tie hoop assembly that enhances field construction performance by integrally forming a plurality of V-shaped tie hoops after constituting the plurality of V-shaped tie hoops in a bundle form, maintains intervals, and enhances reinforcement performance.
A tie hoop is a rebar or a steel hoop that surrounds a main reinforcement, and refers to a rebar or a steel wire that is continuously wound in a circular, rectangular, or a polygonal shape, and reinforces the vertical main reinforcement of a concrete column and prevents buckling (a phenomenon of deflecting horizontally at a limit point of a vertical stress generated in a column structure).
Further, although the tip hoops are generally disposed to surround all the vertical rebars, auxiliary tie hoops of various shapes are added in the interiors of the tie hoops when the disposition interval of the vertical rebars is large or the column has a large number of main reinforcements. A existing auxiliary tie hoop is called as a cross tie and has a bending angle of 90 degrees at one end and a bending angle of 135 degrees at an opposite end thereof, and main reinforcements are installed on opposite sides of the auxiliary tie hoop, whereby bucking of the main reinforcements is prevented and thus a transverse restraint effect of a compressive material is enhanced.
In particular, a V-shaped (or U-shaped) tie hoop replaces the function of the existing cross tie (auxiliary tie hoop), and is a configuration of supplementing an installation disadvantage of the existing cross tie and the disadvantage by which a 90 degree hook portion is released by repeated transverse forces after installation.
The V-shaped tie hoops is individually installed one by one, and thus it is necessary to improve a structure capable of prolonging work time and enhancing construction performance.
As a prior technology related to a conventional V-shaped tie hoop, Korean Patent No. 10-1913818 (entitled ‘Column Reinforcing Structure Using V-shaped Tie Hoop for Vibration-resistant Design and Method for Constructing the Same’) discloses a technology including: an existing column in which rebars are arranged in the interior of concrete; a plurality of main reinforcements arranged vertically outside the existing column; a reinforcing tie hoop arranged to surround the outsides of the plurality of main reinforcements; a V-shaped tie hoop having extending/fixing parts having a V shape and bent upwards and downwards and attached to an outer peripheral surface of the existing column at an end of the fixing part on opposite sides of a bending part, in which an inside of the bending part is attached to an outside of the main reinforcement, and in which the fixing part is coupled to the main reinforcement to face the existing column; and retrofitting concrete installed outside the existing column such that the main reinforcement and the V-shaped tie hoop are buried therein.
However, the prior technology is a technology for arranging reinforcing tie hoops and V-shaped tie hoops together with a main reinforcement outside an existing column when the column is reinforced through retrofitting of concrete.
The present invention has been made in an effort to solve the above-described problems, and provides a V-shaped tie hoop assembly that includes an assembly in which a plurality of V-shaped tie hoops are coupled to each other in a bundle form as the V-shaped tie hoops are taken as one medium, thereby remarkably enhancing field construction performance, increasing a reinforcement effect by effectively maintaining the intervals between the V-shaped tip hoops, and thus minimizing deformation due to an impact in a concrete installing process.
The present invention includes: a plurality of V-shaped tie hoops, each of which has a bending part at the center thereof and anchor parts extending to opposite sides of the bending part, and disposed at different heights at an interval; and a vertical support bar connecting all of the V-shaped tie hoops to integrally couple the V-shaped tie hoops
The support bar may be coupled to the outsides of the bending parts of the V-shaped tie hoops, and
Further, the support bar further includes an inverse U-shaped hook part.
Further, the V-shaped tie hoop assembly may further include fixing clips coupled to the V-shaped tie hoops to increase coupling forces with the main reinforcement located inside the bending parts.
Further, each of the fixing clip may include: an arc-shaped support part bent in an arc shape such that the anchor parts of the V-shaped tie hoops are seated on opposite sides of the inner side thereof; an insertion guide part formed at a lower portion of the arc-shaped support part to be widened such that the V-shaped tie hoop is inserted, and having a width that is smaller than the interval of the arc-shaped support parts; and an elastic operation part formed at the center of an upper portion of the arc-shaped support part to be bent so as to be elastically deformed to opposite sides.
According to the present invention, because several V-shaped tie hoops can be installed in one main reinforcement at the same time by providing an assembly in which V-shaped tie hoops are integrally coupled to a support bar in a bundle form, construction performance can be remarkably increased as compared with a conventional technology of individually installed V-shaped tie hoops.
Further, according to the present invention, because the intervals between the V-shaped tie hoops can be effectively maintained and a reinforcement effect can be increased, deformation by an impact can be minimized in a concrete installing process.
The above and other objects, features, and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which:
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. A detailed description of known technologies related to the present invention will be omitted to avoid making the technical essence of the present invention rather unclear.
Because the conventional tie hoops is individually coupled to the main reinforcement, operation time is long and construction efficiency is very low, and the present invention is made to solve the problems through a V-shaped tie hoop assembly.
The V-shaped tie hoop assembly according to the present invention, as illustrated in
The present invention, as illustrated in
Various materials may be applied to the support bar 200 as a medium for connecting the V-shaped tie hoops 100, but it is preferable that the support part 200 is formed of a metallic material in consideration of a coupling force between the elements and the durability. Further, a method for integrally coupling the V-shaped tie hoops to the support bar 200 may be performed by a separate coupling unit (not illustrated), and may be performed through a bonding scheme such as welding. if the coupling unit is configured to move inside the support bar 200, the locations of the V-shaped tie hoops 100 may be immediately adjusted in the field to be used.
Further, the support bar 200 has to be coupled to the outsides of the bending parts 110 of the V-shaped tie hoops 100. This is because an interference problem occurs when the main reinforcement 1 and the hoop reinforcement 2 are coupled to each other and thus construction quality may be deteriorate when the support bar 200 is coupled to the inside of the bending parts 110.
Further, it is preferable that three or six V-shaped tie hoops 100 are coupled to the support bar 200, but of course, the number of the V-shaped tie hoops 100 may be more than six, and the fixing intervals of the V-shaped tie hoops 100 also may be not only equal but also unequal.
In the support part 200 of the present invention, as illustrated in
The present invention, as illustrated in
The configuration of the fixing clip 300, as illustrated in
The arc-shaped support part 310 is a configuration of supporting the outsides of the opposite anchor parts 120 of the V-shaped tie hoops 100 while surrounding the anchor parts 120, and the opposite arc-shaped support parts 310 are strongly attached by the elasticity of the fixing clip 300 by making the interval between the opposite arc-shaped support part 310 the same as or narrower than the interval between the anchor parts 120 at the coupling portions.
Further, the V-shaped tie hoop is inserted by forming the insertion guide part 320 at an upper portion of the arc-shaped support part 310 in an opened form, and the interval between the insertion guide parts 320 are formed to have a width that is smaller than the interval between the arc-shaped support parts 310 to prevent deviation of the insertion guide parts 320 when the insertion guide parts 320 are seated on the arc-shaped support parts 310. Further, a coupling guide can be stably made by forming a curved portion at a lower end portion of the insertion guide part 320 to be curved outwards.
The elastic operation part 330 is a configuration that is formed between the opposite arc-shaped support parts 310 and is capable of accommodating a width, by which the interval between the arc-shaped support parts 310 may be changed, and the restoring tensions of the arc-shaped support part 310 can maintain a strong coupling force while facilitating coupling by allowing elastic deformation of the arc-shaped support parts 310 as the elastic operation parts 330 are present.
In addition, because the elastic operation part 330 also functions as a handle, the elastic operation part 330 may be conveniently coupled while being pressed by a hand when the fixing clip 300 is coupled while being pressed from the upper side of the V-shaped tie hoop 100. The elastic operation part 330 may be realized while being bent by 90 degrees to further facilitate a pressing operation.
Further, the present invention, as illustrated in
Although the embodiments have been described to described the present invention, various modifications may be made without departing from the technical spirit of the present invention.
