[Prior art and its problems]

Generally, when constructing a concrete building, reinforcing bars are assembled and arranged around the steel frame. A steel reinforced concrete structure made by pouring concrete into a built-in frame structure. , or by pouring concrete around a steel frame structure without using rebar. There are two construction examples, one with a steel-framed concrete structure, and both with a frame structure. Assemble the structure, install formwork around it and pour concrete. The construction procedure involves removing the formwork after the concrete has hardened. place After assembling the frame structure of the building's square columns, four pieces are placed around this frame structure. The work procedure for installing the formwork is to separate it from the separator installation hole of one of the opposing formworks. One end of the separator is protruded through and the separator is directed toward the other formwork. Fasten and support the separator horizontally, then attach the other end of the separator to the separator of the other formwork. By projecting through the motor mounting hole and supporting it by fastening, the two opposing Four formworks are installed in a surrounding manner by holding each formwork around the frame structure. However, when installing the other formwork in this work procedure, it is necessary to separate this formwork. Alignment when the other end of the separator protrudes through the separator mounting hole It takes a lot of time and effort to install the formwork, and it is very difficult for builders to install the formwork. was. In other words, the length of the separator is determined according to the thickness of the pillars of the building being constructed. It is designed and manufactured to be able to fasten and hold the frame, so it is easy to remove the separator from the formwork. The length of the end protruding from the hole is only long enough to screw a fastener such as a nut. Therefore, it is necessary to insert your hand between the formwork and the separator that has already been installed. It is difficult and time consuming because the end cannot be aligned with the mounting hole of the formwork. It is something that costs money.

[Means to achieve the task]

In order to achieve the above purpose, the separator extension aid provided by the present invention is Desired to have a diameter that is the same as or slightly smaller than the diameter of the separator mounting hole opened in It is formed into a long rod shape and can be attached and detached to the end screw of the separator at one end. It is characterized in that it is provided with a screw hole for coaxial screw connection.

[0005]

[Effect]

According to the technical means of the present invention described above, the assembled frame structure can be Insert one end of the separator into the separator installation hole of one of the opposite formworks to be installed around it. Screw the other side with a fastener such as a nut and orient the separator toward the other formwork. After tightening and supporting the separator horizontally, attach the extension aid to the end screw on the other end of the separator. The extension aids are installed coaxially by screwing together the screw holes of the extension aids. Thereby, The length of the other end of the separator has been extended by the length of the extension aid and has already been installed. There is a space between the separator and the mold that allows you to put your hand in. Hold the other end with your hand and align it with the separator mounting hole of the formwork. After the extension aid protrudes through the mounting hole, the extension aid is inserted into the separator. Remove it from the end screw, screw a fastener such as a nut onto the end screw, and attach it to the other formwork. be concluded and supported.

【Example】

An example of the implementation of the present invention will be described below based on a drawing. A steel structure made by pouring concrete into a frame structure 1 in which reinforcing bars 1b are assembled and arranged. An example of construction of a rectangular column of a building with a reinforced concrete structure is shown, and the frame structure 1 is assembled. After that, when the four formworks 2 are installed in a surrounding manner around the frame structure 1, all facing The end screws 3a of the separators 3 installed horizontally between the two formworks 2 are The palator extension aid 4 is screwed and connected, and the extension aid 4 opens into the formwork 2. Pass through the end screw 3a of the separator 3 through the separator mounting hole 2a that is After protruding through, remove the extension aid 4 from the end screw 3a of the separator 3 and Connect two opposing formworks 2 by screwing a fastener 5 such as a nut onto the screw 3a. The frame structure 1 is held in place, and four formworks 2 are attached around the frame structure 1.

[0007] The extension aid 4 has a diameter that is the same as or larger than the diameter of the separator mounting hole 2a of the formwork 2. Form into a rod shape with a slightly smaller diameter and desired length, and attach the end screw of separator 3 to one end of the rod shape. 3a is provided with a screw hole 4a which is detachable and coaxially screwed together. and extended Form the other end (tip) of the auxiliary tool 4 into a tapered shape and attach it to the separator mounting hole 2a of the formwork 2. Configure it so that it can be inserted smoothly.

[0008] Thus, one opposing formwork 2 is installed around the assembled frame structure 1. One end of the separator 3 protrudes through the separator mounting hole 2a. Screw the fastener 5 onto the end screw 3a and turn the separator 3 toward the other formwork 2. After horizontally fastening and supporting the separator 3, it is extended to the end screw 3a on the other end side of the separator 3. By screwing the length auxiliary tools 4 and installing them coaxially, the other formwork 2 sides can be The other end of the separator 3 facing the direction has a temporary length equal to the length of the extension aid 4. There is a gap L between the formwork 2 that is longer and that allows you to put your hand in. is secured, attach the separator to formwork 2 by holding the other end of separator 3 with your hand. While aligning (centering) with the hole 2a, insert the attachment hole 2 from the extension aid 4. After penetrating and protruding through a, insert the extension aid 4 through the end screw 3a of the separator 3. Remove the end screw 3a and screw the fastener 5 onto the end screw 3a to fasten and support the other formwork 2. , two opposing formworks 2 are held around the frame structure 1, and four The formwork 2 can be installed in a surrounding manner.

[Effect of the idea]

As mentioned above, the present invention has the same diameter as the separator installation hole opened in the formwork. Form it into a rod shape with a desired length and a diameter slightly smaller than that of the rod, and place a separator on one end of the rod. A frame structure is constructed using an extension aid with a screw hole that coaxially connects to the end screw. Since the formwork was installed around the body, the formwork's separator installation hole When protruding the end of the separator through the Temporarily lengthen the length and align (center) it with the mounting hole. , can protrude through the mounting hole. Therefore, the formwork cannot be set as before. Problems such as taking time to align the separator end with the parator mounting hole All problems are eliminated, and the end of the separator can be easily and quickly removed from the formwork. Formwork installation workability is improved because it can be fastened and supported by protruding through the attached hole. We have been able to provide a separator extension aid that can improve this.
