Abstract

PURPOSE:To prevent a joined part between beam bottom form materials from causing the crack of a beam by making the joint positions of the fellow beam bottom form materials and of fellow beam side form materials different in each of their longitudinal directions. CONSTITUTION:A buried form 1 for a beam is divided into three pieces of form composing bodies 1A, and the dividing point is set up to be near a changing over point between bending stress and tensile stress in the case where bending load acts on the beam. Next, the form composing body 1A is divided into L-shaped corner form materials 5, 5, a flat plate-shaped beam bottom form material 6, and two sheets of flat plate-shaped beam side form materials 7, and a reinforcing protrusive stripe rib (f) is severally formed on the sides of the insides of the form materials 6, 7 over the whole longitudinal length. Next the joint position P of the fellow form materials 7 and the joint position (t) of the fellow form materials 6 are made to differ in each of their longitudinal directions. Even when the bending load acts on the beam, and resultant stress acts so as to mutually separate the form materials 6, 6, the face part of the form material 7 is made to function so as to back up the form materials 6, 6 against their separation.

In this way, the embedded formwork for walls and pillars / beams is divided into a plurality of formwork materials by stacking the formwork materials on top of each other so that a small storage space is required and the formwork material is easily transported. This is because it is also suitable in terms of handling, and because the weight of a single item is also excellent in terms of handling,
Regarding the buried formwork for long beams, in order to make it even better in terms of transportation and handling, divide it into a plurality of formwork structures in the longitudinal direction, and It takes the form of butt-joining the frame components.

The problem here is the structure of the buried formwork for the beam. That is, as shown in FIGS. 3 and 4, the structure of the conventional buried mold for a beam has a shallow structure in which a mold structure 11A divided into three in the longitudinal direction is connected to a mold part 12 for a corner. U-shaped groove bottom beam form material 13 and 2
It is divided into a piece of frame material 14 for the beam side portions, and these end portions are butt-joined to each other and erected on the pillar-embedded formwork 15. At this time, the formwork structure is formed. 11
Since the butt joint positions of the end portions of A and 11A, in other words, the joint position h of the beam bottom mold members 13, 13 and the joint position i of the beam side mold members 14, 14 are made to coincide with each other. is there.

However, when the joining lines between the form members for the beam bottom and the beam side portions are connected in a straight line in this manner, a load is applied to the beam and tensile stress acts on the beam lower side. When a stress is applied between the beam bottom mold members 13 so as to separate them from each other, a beam side portion which is in a linear joint state with the joint portion of the beam bottom mold members. The mold material 14 for use is also stressed so as to separate the mold materials 14, 14 from each other between the joint portions thereof, and at this time, the mold material 14 for the beam side portion is used for the beam bottom. Since it does not function as a backup against the separation of the formwork material 12, cracks tend to occur in the beam starting from the joint portion of the beam bottom formwork materials 13, 13 and the joint line is straight. Since they are continuous, there is a problem that cracks easily progress along this joining line.
