Abstract

(57) [Summary] [PROBLEMS] To improve work efficiency at the time of assembling and dismantling a PC girder, mainly for hollow girder, in post-concrete work of concrete. SOLUTION: An insert-integrated L-metal fitting 1 is attached to a hollow girder 4, and after finishing concrete, the insert mounting screw portion is clogged with a finish.

Description

[Detailed description of the invention]       [0001]     [Field to which the invention belongs]   The present invention relates to post-collapsing work of PC girder, mainly hollow girder. is there.       [0002]     [Prior art]   Conventionally, mainly in the case of post-cast concrete work of hollow girder, upper and lower After assembling the formwork and dismantling the formwork, fill the holes with mortar etc. for the processing of bolt holes etc. Was.       [0003]     [Problems to be solved by the invention]   With the conventional technology, the inefficiency in assembling and dismantling the formwork and the labor required for finishing There was a problem that it took.       [0004]   The present invention simplifies the work of assembling the formwork and dismantling the formwork, and also enables complicated finishing. This is to make it easy to work.       [0005]     [Means for Solving the Problems]   In order to achieve the above object, the embedded insert-integrated L hardware in the present invention is The embedded type insert 2 is fixed to the L metal fitting 1 with the reinforcing rib with a bolt or the like.       [0006]   In addition, the hollow girder is attached to the hollow girder mounting part 3 of the L hardware 1 with reinforcing ribs in advance. The embedded insert 4 is attached with a bolt or the like.       [0007]   Insert-integrated L hardware attached to hollow girder Then, fix the formwork using hanging bolts, home ties and the like.       [0008]     [Embodiment of the invention]   With the embedded insert-integrated L hardware, the insert and the L hardware with reinforcing ribs are integrated. Be used.       [0009]   FIG. 4 is an example of use.       [0010]   The insert 5 pre-embedded in the hollow girder 4 of FIG. Attach and fix the hollow girder 4 to the hollow girder 4 with a bolt or the like in the hollow girder mounting hole 3 of the hardware 1.       [0011]   Hanging bolt etc. of embedded insert 2 attached to L metal fitting 1 with reinforcing rib Attach hanging bolts, etc. to the attachment parts, apply square steel pipes, etc., and fix the formwork. Figure 4       [0012]   After the ground concrete has been put in and the formwork has been dismantled, plugging into the embedded insert 2 do. FIG.       [0013]     [Effect of the invention]   Embedded insert integrated L hardware is previously embedded in hollow girder 4. Easy to assemble and disassemble the formwork by attaching to the support 5 And the efficiency is greatly improved.       [0014]   Finishing can be completed simply by inserting a pinch into the insert mounting screw portion 2.
