Abstract

PURPOSE:To promote building construction efficiency and to reduce man-power of inserted bar setting work by utilizing effectively separators and plastic cones buried into a wall in a state to remain unused in inserted bars using form setting separators for mounting member such as pipe, cable tray, etc., to the surface of the wall. CONSTITUTION:Anchor bolts 11 are screwed in plastic cones 4 buried into a wall 1, a supporting member 13 is temporarily tacked to the bolts 11 and is fastened with nuts 10, and the supporting member 13 is fixed to the surface of the wall 1.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to formwork setting reinforcement for fixing support members such as pipes and cable trays to a wall surface.

0003

[Prior Art] When fixing support members such as piping and cable trays to a wall, the support members are fixed by embedding metal fittings, reinforcing bars, etc. in the wall and joining the support members to these. There is.

On the other hand, when constructing a wall to which support members are attached, when setting concrete forms 2 provided on both sides of the wall 1, separators 3 and peakons 4 are used to determine the required thickness of the wall 1, as shown in FIG. We are ensuring that Even after the concrete hardens, the separator 3 and the peakon 4 remain unused inside the wall 1.

That is, when constructing the wall 1, a large number of separators 3 screwed to plastic capons 4 embedded near both ends of the wall 1 are arranged in the wall 1 to ensure the necessary wall thickness. . The separators 3 are usually arranged at equal pitches, and are set so that the outer surface of the peacon 4 coincides with the wall surface. As shown in FIGS. 3 and 4, this peakon 4 has a female thread 4b cut on the inner surface of the central through hole 4a, and this female thread 4b allows the separator 3 and another short male thread 8 to be attached to the opposite side thereof. can. This male screw 8
The formwork 2 is inserted through the inner peakon 4 and the outer form tie 5, and the formwork 2 is fixed with the crosspieces 6, short pipes 7, backing plates 9, and nuts 10.

[0006] Concrete is poured into the formwork 2 set by such a construction method to form the wall 1.

After the concrete hardens, formwork 2, form tie 5, crosspiece 6, short pipe 7, screw 8, patch plate 9, nut 10
is removed and the through hole 4a of the peacon 4 is filled to complete the construction. In this process, separator 3 and peakon 4
is embedded in the wall 1 as it is.

[0008]

[Problem to be solved by the invention] In the conventional construction method, the formwork 2
Separator 3 and peakon 4 used to set
There is a problem that the wall 1 is simply embedded in the wall 1 and is not used for any purpose after the construction is completed, resulting in a waste of water.

On the other hand, when attaching support members for structures such as piping and cable trays to one side of a completed wall, embedded metal fittings set in advance at the time of construction or insert bars may be used.
Alternatively, there are issues with poor workability, such as the support being fixed to one wall using post-installed anchors after construction.

The present invention has been made to solve the above problems, and it effectively uses separators and peakons that are used during construction and are then embedded directly into the wall instead of the difference bars that conventionally required unique setting. The purpose of the present invention is to provide a formwork setting reinforcing bar that can be used for forming a formwork and has the functions of a bracing bar and a post-casting anchor. [Structure of the invention]

[0011]

[Means for Solving the Problems] The present invention is constructed by attaching an anchor bolt to a peakon embedded in a wall, temporarily attaching a support member to the bolt, and fixing the support member to the wall surface by tightening with a tightening nut. It is characterized by

0012

[Function] In the present invention, the separator and peakon, which were conventionally embedded in the wall, are used as the embedded members of the differential reinforcement, and the anchor bolts necessary for joining with the support member are attached to them, so that they function as anchors. Add.

[0013] Therefore, by using the separators and peakers that are necessary for setting the formwork during wall construction, it is possible to improve the workability and save labor in setting the reinforcing bars.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, an embodiment of a formwork setting differential bar according to the present invention will be described.

FIG. 1 shows an enlarged view of the main part of the present invention, and FIG.
The same parts are given the same symbols.

In FIG. 1, a peakon 4 is horizontally embedded in a wall 1 so as to be flush with the outer surface of the wall 1. An anchor bolt 11 with threads 12 of the same diameter and the same pitch is screwed into the female thread 4b of the through hole 4a that penetrates the center of the peakon 4 embedded in one wall, and functions as a differential bar and a post-cast anchor. I am adding it.

After the anchor bolt 11 is inserted into the mounting portion 14 of the support member 13, the bolt tightening nut 10 is inserted into the anchor bolt 11.
It is fixed between the wall and the wall.

The support member 13 is an anchor bolt 11
However, since the separators 3 are arranged at approximately equal pitches during construction, the anchor bolts 9 are also arranged at approximately equal pitches, which improves the ease of installation of the support. This is a contributing factor.

[0019]

[Effects of the Invention] According to the present invention, the separators and peakers used when setting the formwork during wall construction are added with the function of reinforcing bars, thereby improving construction workability and saving labor in setting the reinforcing bars. I can do it.
