KR930013404A - Temporary extension beams and their supports - Google Patents

Abstract

The present invention relates to a temporary extension girders and their supports, which are constructed at regular intervals when constructing the floor or ceiling of a concrete building, and having two distances between the substantially parallel upper and lower chords, The main body joined together, the telescopic body inserted into the upper chord of the main body so that the sliding movement can be free from the end side and bend slightly in the shape of a mountain, and the conical joint is attached to the lower chord of the main body to be inserted into the lower chord of the main body. Is composed of a connecting body freely formed, and one of the upper body of the main body or the elastic body to be inserted therein constitutes a plurality of attachment parts at regular intervals, and the other to couple the main body and the elastic agent between the attachment parts. The attachment part is provided, and either one of the lower chords of the connecting body or the main body has a slightly narrower interval than the attachment part installed on the upper chord of the main body. Attachments are provided at regular intervals, and the other side of the lower chord of the connecting body or the main body is configured to attach the lower chord and the connecting body between the lower chords.

Claims (6)

The main body, which is spaced between two substantially parallel upper chords and lower chords, is integrally joined to each other by a reinforcement body, and the upper chords of the main body are inserted so that the sliding motion is free from the end side and slightly refracted in the shape of a mountain. It consists of a flexible body and a connecting body conically connected to the lower part of the flexible body and freely inserted into the lower chord of the main body. The attachment part constitutes an attachment part, and on the other side, the attachment part which couples a main body and an elastic body between the said attachment part is provided, and on one of the lower chords of a connection body or a main body, it is slightly smaller than the attachment part provided in the upper chord of the said main body etc. Attachment parts are installed at regular intervals of a narrow interval, and the lower part of the lower body of the connecting body or main body Girder for the new hypothesis, characterized in that mounting parts configured to join the material and the connection body. In the construction of the concrete girders, the open end of the stretchable girders for the temporary girders is formed with a bottom-shaped c-shaped locking part that is caught on the top of the temporary girders. In the catch of the extension girders for a temporary extension girders which were installed integrally and supported by a wedge body inserted into the wedge insertion hole opened in the support side wall, the width | variety of a part of a temporary extension girdle and a construction of this hypothesis It is larger than the maximum total width of the reinforcement twigs fixed to the upper part of the side frame, and a nail hole is installed in the upper part of the locking part, and when the front end of the support part swings toward the support part, the tip contact piece abuts against the hypothetical side mold face. In order to temporarily receive the upper c-shaped stopper and the temporary extension beams for temporary installation. W is the knocking-shaped upper opening of the U two hyeongbat body to swing freely conical junction a hypothesis that the characteristics of the elastic beams for receiving hinge of that. 3. A temporary extension girder according to claim 2, wherein the support body is disposed in the stopper. 4. A temporary extension girder according to claim 2 or 3, wherein the stopper extends laterally the tip contact piece to be installed side by side, and a nail hole is drilled in the successive installation portion. It forms a bottom open 자 -shaped locking part which hangs the open end of the extension body of temporary extension girders to the top of the temporary side frame when constructing the concrete girders. In the support of the extension girders for temporary installation, which is installed in the furnace and supported by the wedge bodies inserted into the wedge insertion holes opened in the support side wall, the holding plate is fixed to the inside of the temporary side frame; One end edge is continuously installed at the top edge of the jammer plate, and the top plate is placed on the top surface of the temporary frame and the top surface of the twig, and the board is installed at the other end edge of the top plate. A latching part is formed, and a pair of cutting pieces which are cut out toward the support are provided on both sides of the lower part of the substrate. Temporary extension beams, characterized in that the swinging part is freely attached to the engaging portion by a contact plate and a pair of arm pieces whose surface is in contact with the temporary side frame through a rivet shaft inserted into the shaft insertion hole of the blade. Of receiving. A cabinet formed between the top plate piece forms a hook-shaped clasp with an obtuse back plate piece, which is provided with a groove-shaped support piece and extended to the bottom surface of the support piece. A pair of telescopic bodies formed by fixing the open one end of the sliding part of the drilled installation piece through the backboard surface, and from the edge of the opening of the one-step cutout provided on the bottom plate of the groove-shaped upper current both ends. A storage groove for extending the pair of side plates to form a substantially U-shaped accommodating portion piece having a wedge hole penetrating the two side plates and accommodating the girders in the groove between the accommodating portion piece and the upper chord. By forming a part and disposing a reinforcing material between the lower chord, the sliding girders and the receiving groove part can be freely formed. For fixing to the main girder hypothesis storage elastic member for elastic beam theory, characterized in that it is configured to wedge the pair of loading for driving in the wedge hole. ※ Note: This is to be disclosed by the original application.
