DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

1 and 2 are a side view and a perspective view, respectively, of a ladder 100 for installing reinforced concrete according to an embodiment.

The ladder 100 according to the present embodiment may include a first vertical pole 110, a second vertical pole 120, a cross bar 130, and a coupling member 140.

In this embodiment, a method of installing a ladder in a reinforced concrete (LONGI) is proposed. In general, structural reinforcement members (hereinafter referred to as reinforcement rods) are installed in various structures such as ships and buildings to reinforce the strength of the structures. Reinforcing rongi is usually used in the form of 'a', but depending on the situation, various types of reinforcing rongi such as straight type and 'T' shape are used.

1, the ladder 100 according to the present embodiment can be installed in the reinforced rods 2 protruding from the structure 1, and the reinforcement rods 2, The present invention is not limited thereto. There may be various types of reinforcement rods, and other embodiments of the present invention may be modified to accommodate these various types of reinforcement rods.

As shown in FIG. 2, the first vertical legs 110 may be formed as a pair, spaced apart from each other. This is for inserting the second vertical bar 120 into the first vertical bar 110 so that the length can be adjusted as described later.

The first vertical bar 110 may have a polygonal cross section as shown in the drawing, but the present invention is not limited thereto, and a circular cross section pipe member may be used.

The second vertical bar 120 may have a smaller cross-sectional size or diameter than the first vertical bar 110 and may be inserted into the first vertical bar 110. Each of the second vertical legs 120 is inserted into the pair of first vertical legs 110 to move in the vertical direction inside the first vertical legs 110, May be possible.

1 and 2, the cross section of the second vertical bar 120 is formed to have a polygonal shape corresponding to the cross-sectional shape of the first vertical bar 110. However, the present invention is not limited to this and may have a circular cross- And may have any cross-sectional shape if there is no restriction on movement within the vertical bar 110.

Also, in this embodiment, the second vertical bar 120 is described as a member filled with the inside. However, the hollow bar member may be used as in the first vertical bar 110 to reduce the weight of the entire vertical bar.

Both ends of the crossbar 130 are connected to the first vertical bar 110 so that the operator can move up and down the crossbar 130.

As shown in the drawing, the crossbars 130 are provided as a plurality of ladder in the same manner as a general ladder, and the cross-sectional shape of the crossbars 130 is circular. However, the crossbars 130 are not limited thereto. Can be improved.

In addition, the crossbar 130 may also be formed of a material having an embrittlement so as not to be deformed due to the weight of the worker, .

As will be described later, a part of the crossbar 130 may be connected to the second vertical pole 120, and may be located below the ladder 100 for installing the reinforced concrete.

The plurality of crossbars 130 may be directly connected to the first vertical pole 110 through a method such as welding or may be inserted into a first through hole 111 to be described later.

The joining members 140 may be provided on at least one of the upper and / or lower ends of the first vertical bar 110 and / or the second vertical bar 120 to support the first vertical bar 110 or the second vertical bar 120, To the reinforcing rods 2 protruding from the reinforcing rods 2.

In the present embodiment, the reinforcing rods 2 are used in the shape of a rectangle, and the engaging members 140 are designed to be in a loop shape so as to cover both the upper and lower portions of the reinforcing rods 2. However, the shape of the coupling member 140 is a part that can be freely deformed and designed according to the shape of the reinforcing rods 2 and the like.

In general, the ladder 100 according to the present embodiment, which may include the above-described structure, may be fixedly installed to the reinforcing rods 2 through a coupling member 140 without a separate extension, The entire length can be extended by moving the second vertical bar 120 inside the first vertical bar 110 in the vertical direction.

Specifically, the first vertical bar 110 may have a plurality of first through holes 111 spaced apart from each other in the vertical direction. Likewise, a plurality of second through holes 112 may be formed in the second vertical base 120 so as to be spaced apart from each other in the vertical direction.

Here, in order to fix the position of the second vertical pole 120 with respect to the first vertical pole 110, a fixing member 150 is used in this embodiment. For example, as shown in FIG. 2, after the operator completes the desired total length through the vertical movement of the second vertical bar 120, the first through hole 111 formed in the first vertical bar 110 and the second through- And the second through holes 121 formed in the vertical base 120 are aligned. Next, by providing the fixing member 150 passing through the aligned first and second through holes 111 and 121 uniformly, the second vertical bar 120 is no longer movable in the vertical direction and the first vertical bar 110 Can be fixed.

In this embodiment, a bolt member is used for the fixing member 150, and accordingly, the nut member 151 is also used as shown in FIG. 2 for rigid fastening of the fixing member 150.

The fixing member 150 may be formed of a simple rod member other than the bolt member according to the present embodiment, and may further include a pair of first and second vertical bars 110 and 120 having long lengths A rod member may be used. In order to adjust the distance between the crossbars 130 according to the change of the overall length, the long rod member may be used for the same purpose as the crossbars 130, It is possible.

It has been described above that the coupling member 140 can be provided at the upper end and / or the lower end of the first vertical pole 110 and / or the second pole 120. The upper and lower ends of the first vertical leg 110 and the upper and lower ends of the second vertical leg 120 are formed at the upper end and the lower end of the second leg 120 in consideration of the total weight of the ladder 100 for installing the reinforced- ) Are provided. However, this is merely an example, and the number of coupling members 140 can be determined in consideration of various conditions within a range that does not impair the safety of the operator. For example, it is not necessary to install all four joining members 140 in a case where a work is performed only for a short time at a relatively low place, or a work position is frequently changed.

1 and 2, the coupling member 140 is provided in a loop shape to cover all of the reinforcement rods 2 in the form of a loop, Can be doubly fastened to the upper and lower surfaces of the reinforcing rods 2, respectively, so that the rigidity thereof can be further improved.

For example, the coupling member 140 may be a clamp in the form of a loop, and may be double-bolted to the upper and lower surfaces of the reinforcing rods 2, respectively. Also, the first vertical bar 110 and the second vertical bar 120 may be connected by welding.

Such a double fastening structure improves the robustness and can secure the safety of the operator. In addition, since the bolts 141 and 142 are fastened in the conventional wire knotting method, the burden of installation and disassembly is reduced, so that the operator can easily move the ladder 100 for ladder- .

The ladder 100 may include at least one cross bar 130 connected to the second vertical bar 120 at both ends thereof and positioned at a lower portion of the ladder 100 for installing the reinforcement rods.

When the operator extends the entire length of the ladder 100 for ladder installation as required, it is more convenient to move the second vertical pole 120 downward than to move it upward. In the case where the joining member 140 is installed at the upper end of the ladder 100 for attachment of the reinforcing runge as long as the four joining members 140 are not provided when the joining member 140 is installed, Will be more. The necessity of the upper joining member 140 is greater because there is another reinforcement rods 2 that support the first vertical rods 110 in the direction opposite to the structure 1 in the middle (see Fig. 1).

Accordingly, the plurality of crossbars 130 located at the upper and middle portions are connected to the first vertical pole 110, and the plurality of crossbars 130 located at the lower portion are connected to the second pole 120, It is possible to extend the entire length by moving the vertical bar 120 downward (see FIG. 2).

The cross bar 130 connected to the second vertical bar 120 may be connected to the second vertical bar 120 through welding or the like in the same manner as the cross bar 130 connected to the first vertical bar 110, And may be inserted into the through hole 121.

3 is a perspective view showing an extended view of the reinforcement laid installation ladder 100. As shown in FIG.

As shown in FIG. 3, when the entire length of the ladder 100 is extended, the second leg 120 exposed to the outside may be additionally provided with an auxiliary crossbar 131.

When the second vertical bar 120 is extended downward, the horizontal bar 130 connected to the second vertical bar 120 and the horizontal bar 130 connected to the first vertical bar 110, The distance between the crossbars being located is too wide to cause inconvenience between uses.

Accordingly, an auxiliary crossbar 131 may be additionally provided to the second vertical bar 120 exposed to the outside according to the extension, so that the interval between the crossbar 130 can be maintained / adjusted.

In this embodiment, the hook 122 is attached to the second vertical bar 120 through welding or the like. When the hook 122 is exposed to the outside, the auxiliary bar 131 is hooked on the hook 122 The above configuration is implemented. Here, it is preferable that the hook 122 is formed to be relatively small so as not to interfere with the movement of the second leg 120 in the first leg 110. In addition, the width of the auxiliary crossbar 131 may be smaller than that of the crossbar 130 in order to fit the hook 122 formed in such a relatively small size. However, in order to stably support the weight of the worker without deforming the shape, it is desirable to manufacture the worker so as to have relatively high brittleness.

In the present embodiment, a method of installing the auxiliary crossbar 131 through the hook 122 as described above has been proposed. However, other modifications may be made by those skilled in the art.

For example, a groove may be formed in a certain portion of the second vertical bar 120, and an auxiliary cross bar may be formed in a shape corresponding to the shape of the groove to be fitted. Further, the auxiliary crossbar may be inserted through the second through hole 121 described above.

Similarly, although not shown, each of the cross bars 130 may penetrate through the first through holes 111 and the second through holes 121. [ Thus, the operator can adjust the distance between the crossbars 130 according to the type of work. For example, in the case of a work requiring a long time at a certain height or a work requiring a higher accuracy, it is possible to narrow the interval between the cross bars 130 and to stabilize the working posture.

The scope of the present invention is not limited to the above-described embodiments, but the technical idea of the present invention is not limited to the embodiments described above, It will be understood that various modifications, substitutions, and alterations within the scope of the appended claims will be possible, and all such embodiments are to be regarded as being within the scope of the appended claims.
