摘要： PURPOSE:To cut off construction manhours and enhance safety and reduce construction period and construction cost as well by installing an outrigger extended and engaged with a template to be installed to an elevator to both ends of a beam main body. CONSTITUTION:A beam main body 22, which loads a mobile machine room 21, is installed to the top and the length of the beam main body 22 is made shorter than the width of an elevator shaft. Then, the beam main body 22 is moved upward in parallel in the elevator shaft; and outrigger 23 extended and engaged with a template installed at proper spots inside the elevator is installed to both ends of the beam main body 22. Every outrigger 23 is adapted to proceed, and engaged with each template, thereby holding the mobile machine room 21 at its position and repeating this operation one after another in conformity with the progress in the construction of a skeleton. Then, the mobile machine room 21 is moved upward, thereby extending gradually the hoist range of a construction elevator.

摘要： PROBLEM TO BE SOLVED: To provide an elevating mechanism of simple structure, having good working efficiency and capable of generating stable elevating/ sinking motions, and provide a construction machine equipped with such elevating mechanism. SOLUTION: An elevating mechanism 1 includes a mast of variable length varied by increasing or decreasing the number of coupled structural bodies 8 constituting the mast, and a telpher (construction machine) supported by its upper part is elevated and sunk, wherein the configuration is composed of an under-frame 2 supporting the legs 30 of the telpher, a coupling means 3 installed on the under-frame 2 and coupling it with unit structural bodies 8, four jacks 4, and over-frame 5 to support the jacks 4. Each jack 4 consists of a cylinder 41 equipped with a piston rod 42, and the forefront mounting part 43 of the piston rod 42 is fixed to a bracket 22 of the under-frame 2. If the piston rods 42 are contracted in the condition that coupling by the means 3 is disengaged, the under-frame 2 and telpher supported fast thereby are raised.

摘要： PROBLEM TO BE SOLVED: To surely prevent the content of a bucket from dropping through the biting part or opening part of the bucket by grasping a target by a bucket consisting of a lateral pair of shells, and covering the biting part and opening part of the bucket with a cover material. SOLUTION: This device is provided with an arm 3 having a roller having a cover material 2 wound thereon, and the shells 1 of a bucket are opened and closed in the state where the arm tip 8 is situated above the shells 1 or a position A to catch earth and sand. When the shells 1 are closed with the earth and sand being caught therein and the bucket is hoisted upward, the arm 3 is extended over a position B or a rocking position where the arm tip 8 can pass the farthest part (positions C, E) of the shells 1, and a rocking motor 4 is rotated to move the arm 3, so that the bucket opening part is covered with the cover material 2. Thereafter, the cover material 2 is tensed by the action of a spring and closely fitted to the outer surfaces of the shells 1 to prevent the drop of the content of the bucket.

摘要： PURPOSE:To improve accuracy for the fabrication of a steel frame block for an ultra-high building by installing a plurality of jigs on a ground assembly site at the predetermined intervals with high accuracy and rigidity, erecting and securing steel frame column bodies to the jigs and then jointing a steel frame for a beam between the column bodies. CONSTITUTION:A steel frame support body 3 having a cylindrical support frame is erected on a base body 2, and an adjustable leg body 9 is fitted to the outside of the frame 6 via a plurality of stays 8, thereby forming a jig device 1. Thereafter, the predetermined number of the jig devices 1 are arranged on the concrete layer 20 of a rigidly compacted foundation at ultra-accurate intervals, and the base body 2 is secured with anchor bolts. Then, the lower end of a steel frame column body A is inserted and fixed to each support frame 6, and a steel frame B for a beam is jointed between columns A, thereby forming a block. This block is removed from the jig devices 1 and carried to the predetermined position for installation. According to the aforesaid construction, the block for an ultra-high building can be accurately fabricated on the ground, and a construction period can be shortened.
