ことにより前記目的を達するものである。The method for constructing a low-volume opening of a building wall according to the present invention is as follows: Instead of regular reinforcing bars, a sleeve with an internal conical thread is screwed into the threaded part, and a reinforcing bar with a threaded end is installed with the opening part facing each other, and one end surface of the sleeve with an internal conical thread is reinforced with a threaded end. Arranged so that it is in the same plane as the inner surface of the circumference of the opening, one side is in contact with the one end surface of the inner conical threaded sleeve, and the formwork for the four circumferences of the low volume opening is passed through the pre-drilled bolt holes and tightened. The above object is achieved by screwing a bolt into a sleeve with an inner conical thread, and pouring concrete between this formwork and a formwork for a vertical wall, which is set separately. The method of embedding is a sleeve-type threaded joint with an inner conical thread, a threaded reinforcing bar that is screwed into one end of the threaded joint, and a threaded reinforcing bar that is screwed into the other end of the threaded joint to adjust the depth. Prepare the required number of connecting reinforcing bars in advance, and screw both ends of each of these connecting reinforcing bars into the threaded holes of the sleeves with internal conical threads, which are buried facing each other with only one end surface exposed in the concrete. The above objective is achieved by using reinforcing bars within the section.

作秦の工数工費の節減工期の短縮が計れる効果がある。The method for constructing a low-volume opening of a building wall according to the present invention uses a plurality of reinforcing bars with threaded ends, each of which is secured by screwing one end of a sleeve with an inner conical thread to the threaded portion, as reinforcing bars for the four peripheral walls of the low-volume opening. Since the sleeves with internal conical threads were arranged perpendicularly to the circumferential inner surface of the low volume mouth part and so that the other end surface of each sleeve was located on the same plane as the circumferential inner surface of the low volume mouth part, there were no reinforcing bars inside the low volume mouth part. There is no protrusion at all, so the size of the low volume opening can be minimized, and there is no need to bend or stretch the protruding reinforcing bars, which has the effect of reducing man-hour costs.
This invention has the effect of allowing work to be carried out safely without causing damage to the equipment brought in due to contact with the bent part of the reinforcing bars and injury to workers, and the method of burying the low-volume opening of the building wall according to the present invention The closing method is to use a sleeve-shaped threaded joint with an inner conical thread, one end of which is screwed into one end of the threaded reinforcing bar, and one end of which is fixed to the other end of the threaded joint. Screw-in Depth Prepare in advance the required number of connecting reinforcing bars consisting of threaded reinforcing bars that can be freely screwed into the secondary cylinder, and screw both ends of each of these connecting reinforcing bars into the inner conical threaded sleeve embedded in the four peripheral walls of the low volume opening. By placing the reinforcement in the mouth, we arranged a low amount of reinforcement inside the mouth.
Reinforcement arrangement work is simple and easy, and this has the effect of reducing man-hour costs and shortening the construction period for low-volume mouth filling.

の仮開口部の埋閉方法。(2) A plurality of reinforcing bars with threaded ends are fixed by screwing sleeves with internal internal threads into the threaded parts of the upper wall, lower wall, and both side walls forming the four peripheral walls of the temporary opening in the reinforced concrete building wall. This reinforcing bar is combined with a plurality of reinforcing bars perpendicular to the reinforcing bar, the threaded reinforcing bars are arranged to face each other vertically on the upper and lower walls, and horizontally on both side walls, and one part of the sleeve with internal female threads is arranged. A building wall constructed in advance by arranging the end face to be located on the same plane as the circumferential inner surface of the temporary opening, using the reinforcing steel set as an inner frame, and pouring concrete to form the four circumferential walls. In the method of filling and closing temporary openings, a sleeve-shaped threaded joint with an internal female thread is used, one end is screwed into one end of this threaded joint, and a threaded reinforcing bar is fixed, and one end is screwed into the other end of the threaded joint so that the depth can be adjusted freely. A required number of connecting reinforcing bars consisting of threaded reinforcing bars to be screwed are prepared in advance, and the connecting reinforcing bars are installed at the exposed ends of the internal female threaded sleeves buried oppositely in the upper wall and the lower wall and in the both side walls. Both ends of each are screwed in to assemble reinforcing bars in the temporary opening, a formwork is set with these reinforcing bars in between, concrete is poured between the forms, and after the curing period of this concrete has elapsed, the above-mentioned form is A method for filling and closing temporary openings in building walls, which is characterized by removing the frame.
