Description

Non-welded rebar anchoring device capable of adjusting the arrangement structure in response to the rebar arrangement structure and anchoring method using the same

The present invention relates to a non-welded rebar anchoring device that can adjust the arrangement structure in response to the rebar arrangement structure and a fixing method using the same. More specifically, it relates to a rebar arrangement that can fix a structure by anchoring and connecting rebars placed in a structure without welding. This relates to a non-welded rebar anchoring device that can adjust the arrangement structure in response to the structure and a anchoring method using the same.

Generally, when erecting a building, structures such as columns, beams, and slabs must be connected and fixed to each other in various ways. An example of this connection and fixing method is the method of anchoring the reinforcing bars placed in each structure to each other and connecting each structure through this. It is mainly used. At this time, as a method of connecting each structure by anchoring and fixing these reinforcing bars, the method of connecting and fixing reinforcing bars to each other by welding adjacent reinforcing bars is preferred at most construction sites.

Meanwhile, as technology develops and social standards rise, buildings are being built on a larger scale, while regulations on the structural performance of buildings are becoming more stringent. For this reason, recently, high-strength rebar or high-strength rebar with greatly increased yield strength has been used to provide high structural performance of buildings. Here, in Korea, these high-strength rebars or high-strength rebars refer to rebars with a yield strength of 400 MPa (SD400) or more, and rebars with a yield strength of 500 MPa (SD500) or more are also referred to as ultra-high-strength rebars.

However, in the case of these high-strength rebars, when high heat is applied, they deteriorate and greatly reduce the strength against tensile stress. This decrease in strength is a factor that greatly reduces the structural performance of the building itself, even at some points in the high-strength rebars. There is a problem that renders the meaning of using expensive high-strength rebar meaningless. Therefore, buildings using high-strength rebar need an anchorage structure that anchors and connects the rebar to each other without welding.

Referring to Figures 1 to 3, the non-welded rebar fixing device according to an embodiment of the present invention will be comprised of a first fixing part 100, a second fixing part 200, and a connecting part 500. and may further include a template portion 600.

First, before looking at the configuration, the first structure and the second structure are members that constitute a building. In the drawing, the first structure is a vertical member and includes structures such as ordinary pillars, and the second structure is a horizontal member. May include slabs, beams, etc.

The first fixing part 100 is fixed to the first reinforcing bar 11 of the first structure, and is one first reinforcing bar 11 or a plurality of first reinforcing bars 11 depending on the arrangement structure and anchoring position of the first reinforcing bar 11. It can be anchored to the first reinforcing bars (11). In the drawing, the first fixing part 100 shows a case where it is anchored to a pair of first reinforcing bars 11, but in one embodiment, it may be anchored to one or several first reinforcing bars 11. Of course it exists.

The first fixing part 100 is detachably coupled to the first reinforcing bars 11, so that the operator can set and fix the coupling position on the first reinforcing bars 11 in the field before curing the concrete. Meanwhile, the first fixing part 100 is configured to be detachably coupled to the first reinforcing bar 11 and can be fixed to the first reinforcing bar 11 through a clamp method or a locking contact method described later. A detailed explanation will be provided later.

The second fixing part 200 is fixed to the second reinforcing bar 12 of the second structure, and is one second reinforcing bar 12 or a plurality of second reinforcing bars 12 depending on the arrangement structure and anchoring position of the second reinforcing bar 12. It can be anchored to the second reinforcing bars (12). In the drawing, the second fixing part 200 shows a case where it is fixed to a pair of second reinforcing bars 12, but in one embodiment, it may be fixed to one or several second reinforcing bars 12. there is.

The second fixing part 200 is detachably coupled to the second reinforcing bars 12, so that the worker can set and fix the coupling position on the second reinforcing bars 12 in the field before curing the concrete. Like the first fixing part 100, it can be fixed to the second reinforcing bar 12 through a clamp method or a locking contact method.

Below, we will look at various embodiments of the first fixing part 100 and the second fixing part 200.

First, the first fixing part 100 and the second fixing part 200 may be fixed to the first rebar 11 and the second rebar 12 using a clamp method. 4 to 7, the first fixing part 100 and the second fixing part 200 include a first clamp unit 310, a second clamp unit 320, and a coupling means 340. may include.

First, the receiving portion 331 may be formed with a seating groove 3311 in which the outer peripheral surface of the first reinforcing bar 11 or the second reinforcing bar 12 is seated. Here, the seating groove 3311 may be formed in an arc-shaped concave round shape to correspond to the outer circumferential shape of the first reinforcing bar 11 or the second reinforcing bar 12 to be anchored, and the first reinforcing bar 11 or the second reinforcing bar 12 may be formed in a concave round shape. In order to have a wider contact area with respect to the second reinforcing bar 12, the depth and shape of the groove can be set in various ways according to the diameter and curvature of the reinforcing bar. In other words, if the size of the seating groove 3311 is excessively large compared to the reinforcing bar to which it is anchored, it may become difficult to fix the first fixing part 100 to the reinforcing bar, so it is configured in an arc shape as shown, and has a radius of curvature. may be designed to a size corresponding to the outer diameter of the rebar to be anchored.

Furthermore, the seating groove 3311 may be formed as an anti-slip groove to prevent slip with the first reinforcing bar 11 or the second reinforcing bar 12 being seated. The slip prevention groove allows a plurality of protrusions formed to be spaced apart from each other along the longitudinal direction to be seated and inserted on the outer peripheral surface of the first reinforcing bar 11 or the second reinforcing bar 12, so that the first reinforcing bar 11 or the second reinforcing bar 12 is seated in the seating groove 3311. It is possible to prevent the reinforcing bar 11 or the second reinforcing bar 12 from slipping along the longitudinal direction.

Furthermore, the first clamp unit 310 and the second clamp unit 320 are coupled to the side of the seating groove 3311, and the outer peripheral surface of the first reinforcing bar 11 or the second reinforcing bar 12 is seated. It may further include an elastic pad in close contact with the. This elastic pad not only prevents slip between the first clamp unit 310 and the second clamp unit 320 with respect to the first reinforcing bar 11 or the second reinforcing bar 12, but also allows them to adhere more closely without a space between them and increases friction. The binding force can be further improved, and various materials such as known elastic rubber can be applied, and can be fixedly coupled to the side of the seating groove 3311 through bonding, etc.

Meanwhile, although not shown, the first clamp unit 310 and the second clamp unit 320 may have different sizes of the seating grooves 3311 formed in each, and furthermore, the seating grooves 3311 may be symmetrical to each other. It may be formed only in one of the clamp unit 310 and the second clamp unit 320.

The extension portion 332 is coupled to the outer surface of the receiving portion 331 and extends to a set length in the outer direction of the first reinforcing bar 11 or the second reinforcing bar 12, and the connecting portion 500 is combined.

Meanwhile, the extension portion 332 can be formed in various ways depending on the coupling position and arrangement direction of the connecting portion 500, and is formed in a direction perpendicular to the longitudinal direction of the first reinforcing bar 11 to be anchored as shown. It may be formed and positioned to correspond to the arrangement direction of the second fixing part 200, but is not limited to this.

The extension portion 332 extends on both sides of the receiving portion 331, and as shown, both sides can be coupled to adjacent receiving portions 331 to connect the receiving portions 331 to each other. .

The second clamp unit 320 has a structure symmetrical to the first clamp unit 310 and includes the above-described receiving portion 331 and the extension portion 332, and a detailed description thereof has been omitted as it has been described above. I decided to do it.

Here, the coupling means 340 moves the first clamp unit 310 and the second clamp unit 320 in the direction of pressing the first reinforcing bar 11 or the second reinforcing bar 12 to secure the first clamp unit 320. It can be anchored to the reinforcing bar (11) or the second reinforcing bar (12).

In the drawing, the coupling means 340 is provided on both sides of the first clamp unit 310 and the second clamp unit 320, and includes the extension portion 332 of the first clamp unit 310 facing each other. A fastening bolt 341 that penetrates the extension portion 332 of the second clamp unit 320 at the same time and a fastening nut 342 coupled to the end of the fastening bolt 341 are installed so that the worker can use the fastening nut ( The first clamp unit 310 and the second clamp unit 320 are fixed by tightening 342). However, this is one embodiment, and the coupling means 340 can, of course, vary in its fastening position and configuration if the above-mentioned purpose can be achieved. Meanwhile, the coupling means 340 may use a fastening bolt 341 and a fastening nut 342 as shown, but various configurations such as jacks and levers can be applied if they can achieve the above-mentioned purpose. .

The other end of the engaging member 420 corresponds to the shape of the first reinforcing bar 11 or the second reinforcing bar 12 so as to surround and engage with the other outer peripheral surface of the first reinforcing bar 11 or the second reinforcing bar 12. Thus, it can be bent and formed into a concave round shape. Here, the other end of the locking member 420 may be formed in an arc shape so that the first reinforcing bar 11 or the second reinforcing bar 12 does not come off after being caught and contacted, and the length of the bent portion varies. It can be set as follows.

Furthermore, the locking member 420 is formed in a 'U' shape, with one end and the other end respectively penetratingly coupled to the support member 410 and a bent central portion containing the first reinforcing bar 11 or the second reinforcing bar 12. ) may be in engaging contact, and in this case, the connecting means 430 may be coupled to each of one end and the other end of the engaging member 420.

The connecting means 430 serves to connect the support member 410 and the locking member 420 to each other.
