Abstract

PURPOSE:To construct an anchor by drilling, inserting and casting concrete simultaneously in automatic mode and save construction work and eliminate the need for setting-out of a ceiling surface and thereby enhance workability. CONSTITUTION:When starting construction work, a main arm 9 and auxiliary arms 11 and 12 are operated and a hydraulic jack is used to push up a shaft 6 so that a concrete drilling device 14 may be placed against a predetermined drilling hole spot on a ceiling. Then, the concrete is drilled by depressing a pushbutton switch for confirmation. During the drilling work, the thrust force of the concrete drilling device 14 is detected with a pressure sensor and the concrete is drilled by controlling the hydraulic jack by way of a control section 5. Then, after the drilling work is over, air is blasted into the drilled hole, thereby cleaning. Then, an insert is pushed up with a lifter and inserted into a drilled hole with the drilling device 14 and the upper part of the insert is expanded by the stroke of a hammer and fixed in the hole and mounted. A series of anchor work is carried out in automatic mode by performing a similar work. Positioning work is carried out by ejecting an optical beam.

2. Description of the Related Art Conventional anchor construction at a construction site is generally performed from the upper side of a floor slab before placing concrete. However, at recent construction sites, reinforcement work and equipment work are concentrated in a limited short time before concrete is placed in order to promote shortening of the construction period, and it is not necessary to carry out anchor work including black ink work. The procedure is difficult. In addition, even when the angled anchor was set, the position and posture often changed due to contact with the anchor when performing reinforcement work, equipment work, and concrete placing work. For this reason, most of the anchor installation work has recently been done by manual work from the ceiling surface of the lower floor after concrete placement.

[0003]

Problems to be Solved by the Invention These anchor works are used for marking up the ceiling surface and concrete drilling by the upward posture,
It is necessary to clean concrete holes by blowing dust on the face, insert inserts, and insert inserts into the ceiling with a hammer.These manual work are labor intensive and harsh, and labor saving is desired as soon as possible. It was The problem to be solved by the present invention is to save the work from concrete drilling to hole blowing, insert insertion, insert driving or insert attachment, and at the same time to omit the marking work of the ceiling surface.

[0004]

The present invention is provided with a concrete drill and an insert driving device, and based on a ceiling surface and a wall surface or an already installed insert position, a distance measuring tool for optical or ultrasonic waves, a metal or a distance measuring tool. In order to solve the problem, provide a machine that recognizes the next construction position using a distance measuring tool such as synthetic resin and automatically performs a series of anchor construction from alignment to concrete insertion including insert And the means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, a machine for a hydraulic jack, a hydraulic jack, a power source section, a control section, and an insert supply device are provided inside a machine body, and a light beam emitting device for positioning is provided on the upper part of the device. It is equipped with a control panel, a shaft that expands and contracts by a hydraulic jack and an insert supply pipe in the upper center, and a drive unit for moving the device at the tail of the device.

Further, a swivel main arm and a swivel motor for swiveling the main arm are provided above the shaft, and sub-arms A and B swivelable for swivel and a swivel motor for the sub arm are provided on the main arm, and one end of the sub arm is provided. The concrete piercing device with gas blowing function is equipped with an insert mounting device at the other end, and each swivel part is mounted through a bearing.

Further, each of the swivel part and the elevating part is under centralized control by the control part. The insert mounting device is composed of a lifter and a hammer.

The light beam emitting device is installed on the upper surface of the main body of the machine and irradiates the ceiling surface with the light beam obliquely. The inclination angle Tan θ of the light beam is obtained by dividing the numerical value obtained by adding the distance to be separated from the target point to the distance between the light beam emitting position and the anchor construction position by the ceiling height. Although the ceiling height and the distance to be separated are input from the operation panel, the ceiling height may be automatically measured by light or ultrasonic waves.

Before use, the power supply battery of the apparatus main body is charged from an AC 100V power supply. Insert the supplementary insert from the insert insertion slot on the side of the main unit. When the ceiling height is input and the distance between the construction position and the wall is set to 150 m, the positioning light beam is emitted toward the ceiling surface and an L-shaped display is drawn. The apparatus main body is moved and stopped so that the L-shaped display is aligned with the line of intersection between the wall surface and the ceiling surface.

After that, when the work start button is pushed, the main arm and the sub arm turn and stop, and at the same time, the shaft is pushed up by the hydraulic jack and the concrete punching device is pressed against the concrete surface of the ceiling to be punched. After this, concrete confirmation is performed by pressing the confirmation button.
At this time, the concrete punching device is pressed against the concrete surface of the ceiling by the hydraulic jack via the shaft, and the pressing force is detected by the pressure sensor provided between the sub arm and the concrete drilling device, and the hydraulic pressure is supplied via the control unit. This is done by adjusting the jack. The stop of the concrete drilling work is done by the stroke limit switch provided on the side of the concrete drilling device. After drilling is complete,
Clean the inside of the hole by blowing air.

After that, the shaft is lowered, the sub arm is rotated 180 degrees, the shaft is raised, and the insert is attached. Insertion is carried out by pushing up the insert into a hole opened by a concrete punching device with a lifter, inserting the insert into the hole, hitting the lower end of the insert with a hammer to widen the upper part of the insert, and fixing the insert in the hole.

[0012] These operations are also performed at the same time by the concrete boring device and the insert attaching device provided on the sub arm B. Further, either one of the sub arms can be stopped.

After that, the shaft is lowered, the main arm is rotated by 90 degrees, the sub arm is rotated by 180 degrees, concrete drilling is started at the same time when the insert mounting device is replenished with inserts, and then the same work is performed to complete the anchor construction for one room.

[0014]

EFFECTS OF THE INVENTION According to the present invention, work from concrete drilling to hole blowing, insert insertion, insert driving or insert attachment can be labor-saving, and at the same time marking work on the ceiling surface can be omitted. The anchor work of the worker is only the movement management and safety confirmation of the machine.
