METHOD AND IMPLEMENT FOR ADJUSTING BEARING WIDTH IN LAYING OF PRECAST CONCRETE FLOOR SLAB

PROBLEM TO BE SOLVED: To solve the problem that the adjustment of bearing width is uncertain because an operator performs the adjustment of the bearing width depending on his/her individual skill, in a method for adjusting the bearing width by means of a bearing width adjusting implement in the conventional laying of a precast concrete floor slab. SOLUTION: This bearing width adjusting implement 1 is used to adjust the bearing width by performing positioning when laying the precast concrete floor slab on a beam form. A fixing means for detachably fixing the implement body by making a flat plate-like implement body piece-side lateral surface abut on an end of the precast concrete floor slab placed on the beam form is provided on the lateral surface. A lower portion of the implement body is provided with a tapered portion for setting an end surface position of the end of the precast concrete floor slab in a position set within the range of the bearing width, in such a manner as to guide the position to the inside of the beam form from an upper portion of the beam form. An upper portion of the implement body is provided with a tapered portion for guiding an end, placed on the beam form, of an adjacent precast concrete floor slab to the set position.
