Description

[Detailed Description of the Invention] The present invention relates to a support device for attaching a sash frame for a window in advance when constructing a concrete structure. In other words, the work to install window sashes in conventional concrete structures requires chiseling of the opening, welding of sash anchors, mortar filling, and caulking work, and in addition, complaints after the completion of the work require Due to the need to be careful about water leakage accidents, in recent years more and more structures have been constructed using the satsushi pre-installation method. When using this method of pre-installing the sash frame, it is necessary to ensure the position of the sash frame support device attached to the concrete formwork, and if this is uncertain, it may lead to the disadvantage that the sash frame cannot be installed horizontally. Ivy. The present invention focuses on this point, and by installing a sash frame support device at a location corresponding to the sash frame installation position, the sash frame can be reliably placed and supported at an appropriate position on the concrete formwork. The sash frame support member is also constructed to be able to be held in a reliable horizontal position with the upper horizontal surface portion of the sash frame support device, and the sash frame support member can be moved and fixed up and down using adjustment bolts. Furthermore, the sash frame support member is fitted inside by a sliding groove, a fixing bolt, and a tightening nut. Since the internal support members are configured to be able to slide and extend as needed, the installation location of the sash frame support members can be adjusted to suit the thickness of the concrete and the location of the concrete formwork, increasing versatility and making construction easier. This has the effect of saving labor, shortening the construction period, and further reducing construction costs. Preferred embodiments thereof will be described below with reference to the accompanying drawings. FIG. 1 is a plan view of the sash frame support device A of the present invention. The sash frame support member 1 has a concave cross section, and has a sliding groove 2, a fixing bolt 3, and a tightening bolt inside. A nut 4 is provided, into which an internal support member 5 which can be slidably fixed is fitted.

FIG. 2 is a side view of the sash frame support device A, which is constructed of an approximately right triangular iron plate having a width and thickness that is strong enough to withstand structural use. Furthermore, mounting bolts 7 are provided on the side surface portion 6 that contacts the concrete formwork B. Further, a height adjustment bolt 10 is screwed onto the upper horizontal surface portion 8 of the sash frame support device A via a fixed fixing nut 9.
On the other hand, a bolt 10 protrudes through an insertion hole for the bolt 10 bored inside the sash frame support member 1.
It is rotatably attached to an internal support member 5 into which the distal end portion 11 of the distal end portion 11 is fitted. 3 is another side view of the sash frame support device A, FIG. 4 is a plan view of the sash frame support member 1 in a state in which the internal support member 5 is slid, and FIG.
The figure is a side view showing a state in which the height adjustment bolt 10 provided on the upper horizontal surface portion 8 of the sash frame support device A is rotated to move the sash frame support member 1 to a high position.
FIG. 6 is a partially cutaway view of the sash frame support device A of the present invention in use. In the figure, C is the sash frame, D is the crosspiece, and 12 is the insertion hole 13 through which the mounting bolt 7 is inserted into the concrete form B. The nuts for fixing are shown respectively.

Next, the functions and effects of the present invention will be explained as follows. That is, the side part 6 of the sash frame support device A is brought into contact with the concrete form B, the mounting bolt 7 is inserted into the insertion hole 12 drilled in the concrete form B, and the sash frame is supported by the fixing nuts 13. Install device A. Next, the height adjustment bolt 10 fixed to the upper horizontal surface part 8 of the sash frame support device A is rotated to ensure that the top surface of the sash frame support member 1 is positioned inside the sash frame C. and further slide the internal support member 5 of the sash frame support member 1 by operating the sliding groove 2, the fixing bolt 3, and the tightening nut 4, so that the end of the internal support member is aligned with the concrete formwork B.
Place the crosspiece D on the sash frame support member 1 to support the sash frame C, and then move the concrete formwork B
This completes the installation of the sash frame C.

Since the sash frame mounting device of the present invention is constructed as described above, the sash frame mounting device can be installed at a location corresponding to the sash frame mounting position in the concrete formwork, thereby increasing the height of the sash frame support member relative to the sash frame support device. can be freely adjusted, and the length of the sash frame support member can also be adjusted, so even if the position of the sash frame support device originally attached to the concrete form is slightly shifted vertically or horizontally, the sash frame can be kept in the specified position. Since the sash frame can always be maintained and installed horizontally, it can be adjusted according to the type of concrete thickness where the sash frame is installed and the position of the concrete formwork, increasing its versatility and saving labor in construction. This method has the excellent effect of shortening the construction time and reducing construction costs, thereby enabling the construction of concrete structures.
