BACKGROUND OF THE INVENTION The present invention relates to a novel metal frame, in which only a plurality of locking anchor plates, such as a metal frame, are pre-locked to a mounting position of a structure such as a building using connecting bolts or the like in advance. If you use a small screw, fitting set, etc. on the same anchor plate, you can install the new metal frame accurately and securely without using fire, etc.
A plurality of locking anchor plates to be used are equipped with male or female tools of a set of fittings and a fitting tool set at the inner and outer ends of the new frame using the same anchor plates and small screws. This is a form that secures space and provides a loose hole for connecting to anchor bolts for connecting structures such as buildings.The structures such as buildings and the new metal frame are articulated and locked via the same anchor plate, and new Enables mounting of metal frame,
[0003] In order to easily mount the new metal frame to the locked anchor plate, the door mounting side frame and each side member of the rear side of the door stop are divided into two parts. Inserting only the door mounting side frame from which each side member has been removed is installed at a predetermined position, and the end of the attached anchor plate and the connection margin of the end of the frame are articulated and locked using a plurality of small screws and the like. After attaching either the male or female member of the fitting set installed on the back side of the new frame material to the same plate, once removing and removing each back member on the back side to form a new metal frame by the same procedure as above,
[0004] If a sealing material is filled at the inner and outer four-peripheral connecting portion with the wall floor and the like and then a filling material such as dry mortar is filled, a new metal frame having secured installation strength and fire prevention performance can be obtained.
[0005]
2. Description of the Related Art Removal of a metal frame and the like for repair of fittings installed in a building and installation of a new metal frame are performed by previously embedding an anchor plate attached to the back side of the metal frame embedded in a wall floor or the like. Although the method of articulating and locking by welding or the like to the hardware that is
[0006] In most cases, the use of fire is prohibited in on-site work in a building in use. Therefore, a simple method adapted to on-site work in which an integrally molded metal frame is articulatedly locked to an existing wall floor or the like is used. It is no exaggeration to say that there are almost no locking methods.
[0007]
According to the present invention, a new frame 1 is divided into two parts, a door mounting side frame 11 and a frame member 12 which covers each side of the rear side of the door, and is manufactured. At the time of the on-site mounting work of the new frame 1 assembled using the above, only the door mounting side frame 11 from which the frame member 12 has been once removed is articulatedly locked to a predetermined portion of the wall floor a, b, c, etc. after removing the existing frame. Since the inner frame material has been removed from the door stop, it is easy to perform locking work,
A plurality of specially processed anchor plates 2 are locked in place at predetermined locations using anchor bolts 3 or the like, and connection margins 21 and 22 at both ends of the anchor plate 2 and connection margins 111 and 113 at the ends of the new frame. Are connected and locked using a plurality of small screws 5 at the same time, and at the same time, one of the male and female 41, 42 of the fitting tool set 4 attached to the back of the new frame material is fitted to each other, and The new frame 1 is anchored by using screws 5 or the like, or by fitting one of the male and female 41, 42 of the fitting set 4 together with the frame member 12 covering each side of the door mounting side frame 11 and integrating them. It is articulated and fixed firmly to structures such as wall floors I, B, and C through the plate 2,
[0009] A seal material 61 is filled in a seal margin 6 around the inner and outer contact portions between the newly installed metal frame 1 and the wall floors I, B, C, etc., and then a filling material 7 such as dry mortar is filled in the internal space. By densely filling, a new metal frame 1 for fire prevention can be installed.
[0010]
SUMMARY OF THE INVENTION In accordance with the above object, the present invention provides a method of installing a new metal frame 1 without reducing the opening dimension of an existing frame removed during renovation work, which is usually a new metal frame. Instead of mounting a plurality of anchor plates 2 mounted inside the frame 1, a specially machined multifunctional anchor plate 2 is attached in advance, and a new metal frame 1 is mounted on the wall floor through the plate 2. As a method of securely articulating with structures such as
After removing the existing frame and all of the filling material such as mortar, engraved anchor bolts 3 and the like for mounting the anchor plate 2 processed into a special shape using a steel plate or the like at a plurality of predetermined positions are mounted on the wall floor. Firmly attached to structures such as i, b, c, etc.
The anchor plate 2 to be used is constructed by connecting the new metal frame 1 to the front and rear ends of the new metal frame 1 at the front and rear ends 111, 113 and a plurality of small screws 5 inside the wall floor a, b, c. Connection margins 21 and 22 at both ends of the anchor plate 2 to be articulated,
A loose hole 23 for fixing a sculptured anchor bolt 3 or the like anchoring to a structure such as a wall floor a, b, c, etc., and
After fitting one of the male and female 41, 42 of the fitting set 4 to the frame member 12 covering each side of the door mounting side frame 11 of the new metal frame 1, one of the remaining male and female 41, 42 is fitted. Is connected to the anchor plate 2 by using a small screw 5 or the like as necessary, for example, by inserting a liner or the like into the anchor plate 2 and integrated with the anchor plate 2 to articulate the door mounting side frame 11 of the new metal frame 1. After doing
A plurality of fittings 4 are fitted to the door back side 112 of the door mounting side frame 11 and a frame member 12 covering each side of the door mounting rear side to connect the door mounting side frame 11 and the frame member 12. At the same time as the knots, if the small screws 5 are fastened at the rear connection allowance 113 and the anchor plate connection allowances 21 and 22, the entire new metal frame 1 is formed into a structure such as a wall, floor, b, and c via each anchor plate 2. The articulation can be locked correctly.
The sealing margin 6 which contacts the wall floors A, B, C, etc. is filled with a sealing material 61 of a type suitable for the purpose.
The filling material 7 such as dry mortar is composed of a dry material obtained by mixing fine aggregate and an appropriate amount of Portland cement and an aqueous solution mixed with a well-known setting accelerator. If a dry material mixed with a suitable amount of aqueous solution is injected using a flexible tube or the like into the gap of Portland, Portland cement and the aqueous solution react and the injected dry material hardens and the gap can be densely filled. It is possible to install a new metal frame 1 for fire prevention.
