[Technical field to which the invention belongs]

 The present invention relates to a retaining frame structure for a door frame mounting opening in a building formwork.

[0002]

[Prior art]

 In recent years, standardized unitized metal foam, which has become widespread as a building formwork, has become more and more important in the building industry because it can be machined to improve work efficiency and obtain high quality. In addition, as a suspension frame for installation of door frames, window frames, etc., which is applied to large-scale building construction work in accordance with the standardized unitized metal foam, Taiwan Patent Application Publication No. 1 called a pre-fitting grouting method. No. 253007 has been developed. As shown in FIGS. 10 and 11, for example, the door frame, window frame, and other mounting opening retaining frame structures of this type of construction form are, for example, a door frame 10a, which is previously supported by an auxiliary frame 11a. Erected and fixed so as to straddle both inside and outside frame panels 12a and 13a of the building form 1a, and after that, concrete mortar was driven into the form 1a to perform wall molding and installation of the door frame 10a. It is done. This has the advantage of simplifying the door frame installation process in a large-scale building construction work, saving labor, and shortening the construction period, as well as improving work efficiency and quality. is there.

[0003]

[Problems to be solved by the invention]

 However, there are still the following problems. (1) While there is an error in the thickness size of the door frame 10a, there is also an error in the thickness size of the wall to be molded. Therefore, when the thickness of the door frame 10a is smaller than the wall thickness, the door frame 10a does not come into close contact with one or both of the side frame panels 12a and 13a of the mold 1a, and the mortar leaks. On the contrary, when the thickness of the door frame 10a is larger than the thickness of the wall, the door frame 10a cannot be press-fitted between the both side frame panels 12a and 13a of the form 1a. Further, the gasket packing provided around the door frame 10a is often damaged or pressed and deformed due to an improper operation at the time of mounting the frame, which causes mortar leakage. Further, one side edge of the side plate of the door frame 10a is generally projected from the wall surface. However, since there is an error in the thickness and wall thickness of the door frame 10a, it is often the case that another strip is attached to the one side edge. In many cases, it is more prominent, and a secondary process for that is required, which is inconvenient and raises the cost.

(2) If the surface of the door frame 10a is not completely waterproofed, if the door frame 10a is fitted between the side frame panels 12a and 13a and grouting, the door frame 10a is mortared or rained. It absorbs moisture due to and easily deforms. Further, when the door frame 10a is made of metal, if the component mounting holding position before grouting is slightly displaced, subsequent mounting work becomes difficult. Further, if the supporting force of the supporting member of the door frame 10a is not sufficient, the door frame 10 is easily inclined and deformed by the pressure of the concrete mortar during grouting.

(3) Since the door frames are stocked early and fitted into the building formwork immediately after the start of construction, the funds must be input early and the construction cost becomes high. In addition, there is a problem in that it must be maintained and protected in a flawless state until the construction is completed, which is a difficult task.

In view of the problems of the conventional frame structure for holding the door frame mounting opening in the building form, the present invention is designed to be used for reassembling and assembling metal foam for building, and to mount the door frame according to the wall thickness to be molded. An object of the present invention is to provide a retaining frame structure for a door frame mounting port in a building formwork in which the thickness of the retaining frame of the mouth can be adjusted and at the same time the peripheral side surface forms a sealing surface to prevent leakage of mortar. .

Each side frame frame is fixed to the building form by inserting a bolt through the elliptical hole and screwing to the side frame panel of the corresponding building form, and the sealing surface is attached along the peripheral wall of the door frame mounting opening. Are configured to form.

A sleeve body in which at least one set of holding members is fixedly installed between the both side frame members, and the fixing members are fixed to the both side frame members and fitted to each other so as to be slidable relative to each other. And the bush body so that the both side frame frames can be held in parallel, or the upper and lower sides can be respectively attached to the center parts of the both side frame frames located at the upper end of the door frame mounting opening. It is possible to adjust the lateral width of the door frame mounting opening by inserting and fixing the lower long ladder-shaped adjustment plate and selecting and using the adjustment plate of appropriate width and length size, or Insert a gasket strip between the parts of both partition plates that are in close contact with each other, and also fit a gasket strip at the appropriate extension connection site between the partition plates and the side edge frame plates of the frame frames on both sides. Or the above partition plates are in close contact with each other. A convex frame is fixed on each side of the concrete mortar drive-in section, or a wooden frame is attached on each side of the side facing the concrete mortar drive-in area where the partition plates are in close contact with each other. It is even more preferable to screw the fixed block.

Insert and fix it in the center of the upper end of the body, move the bolts appropriately within the above elliptical hole according to the lateral width of the door frame attachment port, and screw it to the corresponding building form, then the two-sided frame frame will be closed. It can be positioned so that it corresponds to the width of the frame mounting port. In this case, if there is an error between the thickness of the door frame and the thickness of the wall to be molded, the partition plates of the frame frames on both sides must be slidable in close contact with each other. Therefore, the peripheral surface between the frame frames on both sides can be adjusted and formed as a sealing surface which cannot leak mortar according to the wall thickness to be molded. Since the holding member formed by at least one set of the sleeve body and the bush body fitted so as to be slidable relative to each other is fixedly mounted between the both side frame frames, the both side frame frames are parallel to each other. Can be held. Then, when the grouting process is completed and cured and solidified and then dismantled, the adjustment plate etc. can be loosened and removed, and each member can be retracted and removed from the building formwork. When the building form is suspended by, the wall with the door frame attachment opening is completed. In addition, each member of the disassembled holding frame can be used in the same way as the building formwork, and if other door frame mounting openings of different sizes are constructed, the adjustment plate of that size can be adjusted to an appropriate size. It may be replaced with a new one, and the depth dimension of the retaining frame of the door frame mounting opening may be adjusted by sliding the partition plate appropriately in close contact with each other to newly assemble.

[Effect of the invention]

 The present invention configured as described above has the following advantages and effects. (1) The door frame attachment holding frame structure assembled by the above-mentioned members forms a frame with a peripheral surface which can be adjusted by sliding expansion and contraction independently to form a door frame attachment port 14 for blocking concrete mortar. It becomes the reservation frame. Therefore, when both frame frames are combined, the efficiency of assembling the holding frame and the usability of the side frame frame are improved without being restricted by the degree of parallelism and the thickness of the door frame. Further, the thickness of the door frame mounting opening 14 can be appropriately adjusted according to the wall thickness size, and one side edge of the side wall of the wooden door frame can be fixedly mounted inside the door frame mounting opening integrally with the door frame. It does not require a secondary process such as technology and can reduce the cost. Furthermore, since the wall surface of this door frame mounting opening is quite smooth, as shown in FIG. 5, the door frame 16 and the tile 160 are joined together. The surface is relatively flat and beautiful. (2) The door frame is fitted into the door frame mounting opening in a subsequent process after molding the door frame mounting opening with the holding frame. Therefore, the door frame does not get wet and deformed during grouting or rain. Further, since the door frame is mounted in the door frame mounting opening after completion of grouting, it is not deformed by the pressure of the concrete mortar and the holding position for mounting the members is not displaced. Even if the wooden door frame is deformed due to an error, it can be corrected and arranged by the holding rod 19 in the mounting process. (3) Since door frames are purchased and installed after the finishing process in the latter half of the construction, it is not necessary to invest funds early, and the time to maintain and protect them is also shortened, resulting in labor and cost. There is an effect that can be saved.
