Description

[Technical Field]

[0001] The present invention relates to a reinforcing member for reinforcing steel bars arranged inside a block wall. [Background technology]

[0002] Conventionally, there are reinforcing members that reinforce the reinforcing bars placed inside block walls. For example, Patent Document 1 describes a reinforcing member that has slits formed in it and is attached to the reinforcing bars by fitting the reinforcing bars into the slits. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-026662 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the reinforcing member in Patent Document 1 had to be fixed with a separate member such as a clip after being attached to the reinforcing bar to prevent it from coming off the slit. Furthermore, a lot of force had to be applied to fit the reinforcing bar into the slit, which increased the work time. Furthermore, when attaching to an L-shaped reinforcing bar, the reinforcing member had to be fitted into both the part extending upward and the part extending horizontally from the bottom of the reinforcing bar, which meant that the dimensions of the reinforcing member had to be accurately determined to match the reinforcing bar.

[0005] Therefore, an object of the present invention is to provide a reinforcing member that can be easily attached to a reinforcing bar without requiring any extra parts. [Means for solving the problem]

[0006] In order to achieve the above object, the invention described in claim 1 is a reinforcing member for pre-reinforcing steel bars, which consists of a vertical portion that is inserted into the interior of a block wall and extends upward, and a horizontal portion that extends horizontally from the lower end of the vertical portion and is fixed to the foundation, and which has a cylindrical main body through which the vertical portion can be inserted, a support portion that extends horizontally from the lower end of the cylindrical main body, and a semi-cylindrical retaining portion that is provided on the support portion and extends downward, and is characterized in that when the vertical portion is inserted into the cylindrical main body and the support portion is aligned with the upper surface of the horizontal portion, the retaining portion covers the horizontal portion from above and is positioned. [Effects of the Invention]

[0007] According to the present invention, the reinforcing bar comprises a cylindrical main body through which the vertical portion of the reinforcing bar is inserted, a support portion extending laterally from the lower end of the cylindrical main body, and a semi-cylindrical restraining portion provided at the tip of the support portion that covers the upper part of the horizontal portion when the support portion is aligned with the upper surface of the horizontal portion. Therefore, the reinforcing member can be attached to the reinforcing bar by simply inserting the vertical portion of the reinforcing bar into the cylindrical body, aligning the support part above the horizontal portion, and positioning the retaining part over the horizontal portion. In addition, there is no need to prepare a separate part to secure the reinforcing member, and there is no need to significantly change the dimensions of the reinforcing member to match the shape of the reinforcing bar. [Brief explanation of the drawings]

[0008] [Figure 1] FIG. 2 is a perspective view showing a reinforcing member according to the present invention. [Figure 2] FIG. 10 is a side view showing the work of attaching a reinforcing member to a reinforcing bar. [Figure 3] FIG. 10 is a side view showing the reinforcing member in use. DETAILED DESCRIPTION OF THE INVENTION

[0009] An embodiment of the present invention will now be described with reference to the accompanying drawings. Fig. 1 is a perspective view showing a reinforcing member 1 according to the present invention. Fig. 2 and Fig. 3 are side views, with Fig. 2 showing the work of attaching the reinforcing member 1 to a reinforcing bar L and Fig. 3 showing the reinforcing member 1 in use.

[0010] The reinforcing member 1 is a steel member that reinforces an L-shaped reinforcing bar L that is placed inside the block wall 100. As shown in Figure 3, the block wall 100 is made up of a concrete base 101 and concrete blocks 102, 102... that are stacked upward from the base 101. The reinforcing bar L is an L-shaped member that consists of a vertical portion 103 that is inserted into the blocks 102, 102... and extends upward, and a horizontal portion 104 that extends horizontally from the bottom end of the vertical portion 103 and is fixed to the base 101.

[0011] As shown in Figure 1, the reinforcing member 1 comprises a cylindrical main body 2 extending upward, a support portion 3 extending laterally from the lower end of the cylindrical main body 2, and a retaining portion 4 provided at the tip of the support portion 3. The cylindrical main body 2 is a cylindrical member with a hollow center, and its dimensions and shape are determined so that the vertical portion 103 of the reinforcing bar L can be inserted through it. The retaining portion 4 is a semi-cylindrical member that widens downward, and its dimensions are determined so that when the support portion 3 is placed along the top surface of the horizontal portion 104, it will cover the top of the horizontal portion 104.

[0012] The construction procedure for a block wall 100 using the reinforcing member 1 will now be described. A reinforcing bar L is placed at the construction position of the block wall 100. Next, as shown in FIG. 2 , the reinforcing bar L is inserted from above the vertical portion 103 into the cylindrical body 2 of the reinforcing member 1. After the vertical portion 103 has been inserted into the cylindrical body 2, the support portion 3 is aligned with the upper surface of the horizontal portion 104 of the reinforcing bar L, and the retaining portion 4 is placed over the horizontal portion 104, thereby positioning the reinforcing member 1. After attaching the reinforcing member 1 in this manner, the foundation portion 101 is created on top of the horizontal portion 104, support portion 3, and retaining portion 4, and blocks 102, 102, ... are installed so that the vertical portion 103 and cylindrical body 2 are inserted through them, thereby completing the block wall 100.

[0013] The reinforcing member 1 of the above embodiment comprises a cylindrical main body 2 through which the vertical portion 103 of the reinforcing bar L is inserted, a support portion 3 extending laterally from the lower end of the cylindrical main body 2, and a semi-cylindrical restraining portion 4 provided at the tip of the support portion 3 and covering the upper side of the horizontal portion 104 when the support portion 3 is aligned along the upper surface of the horizontal portion 104.

[0014] Therefore, the reinforcing member 1 can be attached to the reinforcing bar L by a simple procedure of inserting the vertical portion 103 of the reinforcing bar L into the cylindrical main body 2, then aligning the support portion 3 above the horizontal portion 104 and positioning the retaining portion 4 over the horizontal portion 104. Furthermore, there is no need to prepare a separate member to fix the reinforcing member 1, and there is no need to significantly change the dimensions of the reinforcing member 1 to match the shape of the reinforcing bar L.

[0015] The reinforcing member according to the present invention is not limited to the above-described embodiment, and the overall configuration of the reinforcing member as well as the components constituting the reinforcing member can be appropriately modified as needed.

[0016] For example, in this embodiment, the shape of the clamping portion 4 is semi-cylindrical, but it may be appropriately changed to a shape such as a semi-rectangular tube with an open bottom, as long as it can fit in such a way that it holds down the horizontal portion 104 of the reinforcing bar L from above. Furthermore, in this embodiment, the holding portion 4 is provided at the tip of the support portion 3, but the position where the holding portion 4 is attached may be changed as appropriate.
