Description

  In the construction of a lightweight steel partition wall of a building, the present invention is a strut member between slabs and a frame so that the construction work can be progressed by separating the wall construction and the joinery construction from the current situation where different contractors work while crossing the work. Easy installation construction method of non-welded dry assembly type door frame structure of door frame body that can be constructed regardless of the progress of lightweight steel partition wall opening using positioning board and L-shaped clamp fixing jig About.

In office buildings, tenant buildings, schools, condominiums, etc., there are many lightweight steel partition walls other than the main structure, and the lightweight steel partition walls
A door is always provided as an entrance. In the construction industry, where the shortage of human resources and technicians is currently becoming a problem, the construction of lightweight steel partition walls, where dissimilar contractors make progress while crossing work, has an impact on other industries, resulting in construction delays and rushing. It is becoming a serious problem such as an increase in the number of workers in construction, and a method for finishing a lightweight steel partition wall that can solve these problems is desired. Therefore, we are aiming to develop steel fittings that can be attached regardless of the progress of construction of lightweight steel partition walls.

In the construction of lightweight steel partition walls and steel fittings for buildings, the work processes of wall contractors, steel joinery contractors, and other contractors are now progressing in a mixed manner, which has a considerable impact on the overall finishing process. ing. There is a need for new ways to improve this traditional interworking process. Therefore, in order that the steel joiner can perform construction without being affected by the progress of the construction work of the wall supplier, the strut members between the slabs, the frame positioning board, and the frame suitable for the positioning board are set at the planned doorway door position. It aims to develop a non-welded dry assembly door frame.

In the construction of lightweight steel partition walls in buildings, the door frame consists of a screw-fixed assembling main frame and a screw-fixing assembling-type attached frame in order to change the flow so as not to affect the construction schedule of the entire building. It is easy to carry in, place and store in a two-part structure. Furthermore, non-welding with no fire risk allows safe work, creates a smooth work flow, and increases the number of unreasonable personnel at the construction site. It aims to eliminate and to comply with the work schedule.

When assembling the door frame to the opening where the wall has been completed, the step of fitting the stiffener-shaped bracket to the first frame to be fixed to the finished wall edge, on one wall side of the finished wall opening A step of attaching the first frame having a U-shaped groove to the wall edge using an L-shaped angle, the first frame from the other finished wall surface side of the opening with the wall surface The second frame formed in a structure in which the tip portion enters into the U-shaped groove is sandwiched from both sides of the frame, and the frame is fixed. A door frame mounting construction method has been proposed (see Patent Document 1).

In addition, in a door constructed in the inspection opening of a lightweight steel wall preceded by finishing work, a door manufactured with a dimension 3 to 5 mm smaller than the opening dimension in the finished wall opening is provided on the back side of the reinforcing material opening. It is structured to be held by a door frame attached on the inside, and the door frame consists of two vertical members and 0 to 2 horizontal members, each using a separate structure and using screw members for the lightweight steel wall base material. The vertical and horizontal members can be moved when fixed, the vertical member is used as a mounting member for the door hanging bracket and door key bracket receiving material, the horizontal member is used for the door of the door, and the vertical member. There has been proposed a construction method for attaching a door outside the door frame that can be used as a connecting member for members and hinged to the door body from the front side so as to be substantially the same as the wall board surface (see Patent Document 2).

A first frame provided at an opening edge on one wall surface side of the opening of the wall surface, and a second frame provided at an opening edge on the other wall surface side of the opening; The door stopper provided at the tip inside the opening and the back end of the door stopper, the inner tip of the second frame overlapping the door stopper together with the door stopper from the back side A door frame in which a holding portion to be sandwiched is formed has been proposed (see Patent Document 3). However, for these, the construction method was to perform the fitting work of the opening in a considerably advanced state as a building, but a method that can be constructed at the time possible in the case of Allland in the door construction work has not yet been proposed. Not.

About such a door frame, what was formed from the two frame bodies of the inner side frame provided in the one wall surface side of an opening part, and the outer side frame provided in the other wall surface side is known. It has an upper frame, a lower frame, and left and right vertical frames to be attached to the opening of the building, and has mounting pieces that protrude outwardly on the mounting surface side of the upper frame, the lower frame, and the left and right vertical frames, respectively, Each attachment piece is provided with a building opening member having a cutting groove at the base (see Patent Document 4).

Further, the joinery frame is constituted by a joinery frame main body formed with a through hole for adjusting at least the mounting member with a tool, and a joinery frame cover that can cover the through hole and can be coupled to the joinery frame main body. Mount the joinery frame body on the base frame using the mounting member while making necessary adjustments such as verticality, straightness, gap adjustment, etc., and then suspend the door and then cover the through hole A method of joining a joinery frame cover to the joinery frame body has been proposed (see Patent Documents 5 and 6).

A step of driving an angle material into the floor slab corresponding to the mounting opening of the frame to determine the position of entry and exit, a step of building a door frame in the mounting opening, and a level / building adjustment with a rotating member such as a bolt; A door frame mounting method has been proposed that includes a step of fixing the casing and the head of the rotating member with an adhesive such as an epoxy resin (see Patent Document 5). However, there has been no door frame fixing aid that can be satisfactorily installed. Moreover, many welds are used partially.

Providing unit push-in and assembly methods for general housing such as concrete apartment houses, wooden houses, steel-framed houses, etc., necessitating joisting for joisting, joist finishing, plywood nailing, and parts The purpose is to further reduce the labor of carpenters at the construction site.

A step of driving an angle material into the floor slab corresponding to the mounting opening of the frame to determine the position of entry and exit, a step of building a door frame in the mounting opening, and a level / building adjustment with a rotating member such as a bolt; A door frame mounting method has been proposed that includes a step of fixing the casing and the head of the rotating member with an adhesive such as an epoxy resin (see Patent Document 7). In addition, a sliding door frame retrofitting method is also provided that allows the sliding door frame to be constructed on the wall after the wall cloth has been constructed without impairing the appearance of the sliding door frame (see Patent Document 8).

In the opening frame attached to the building frame of the building, the vertical member of the opening frame is attached to the housing frame in a state where the vertical degree is obtained by the adjusting mechanism, and the adjusting mechanism is attached to the housing frame. An opening frame composed of a fixing member and a positioning member that positions the longitudinal member of the opening frame with respect to the fixing member has been proposed (see Patent Document 9).

In general, in the construction of a door frame body with a lightweight steel partition wall, the door installation work was performed after the wall work was completed and the interior was finished. However, the parallel work of each construction became common sense in shortening the construction period, and it is expected that the door frame will be assembled at the opening where the wall surface is not completed, and that the door construction will be performed early. Yes. In other words, it may be performed when there is no wall construction, and there are many welding works when mounting.

JP 2011-80305 A Japanese Patent Laying-Open No. 2015-151854 JP 2010-189872 A JP 2000-220347 A JP 2009-24336 A JP 2006-233604 A JP 2002-303081 A JP 2000-110443 A JP 2009-235881 A

In the construction of entrance and exit steel fittings installed in the lightweight steel partition walls and wall openings, the partition walls can be separated after the interfacing work of wall base construction contractors, board construction contractors, joinery contractors, cloth pasting contractors, paint contractors, etc. Construction is complete. For this reason, each supplier is the bottleneck of the work efficiency of each supplier over the work start time. Among them, joinery contractors are a major bottleneck due to remarkably different product production lead time and construction time. Further, in Patent Document 1 proposed by the present inventor, the door frame body is assembled at the opening portion where the wall surface is completed, but the steel frame is opened at the opening portion where the wall surface is not completed. It is difficult to adapt to assembling the door frame. It will be necessary to solve the assembly in these states.

  In addition, the shortage of human resources and technicians in each industry is becoming more serious, and it is impossible to go to the same site many times. If the joinery work is delayed, the wall construction company will leave the finish around the opening of the entrance and exit, stop the work, and finish the rest after the completion of the joinery work. In the opposite case, if the wall construction is delayed, the joinery contractor does not have an opening reinforcing member and cannot perform the installation work. At a later date, after the construction of the wall foundation is completed, it will be reattached, and the current situation is that it does not proceed according to the basic process.

In addition, in the remodeling work such as when specifications change, the number of days from the arrangement of the frame and door of the joinery contractor to the arrival and the number of days from the arrangement of the wall construction member to the arrival of the wall contractor are different. A waiting period occurs. The construction period of the building is fixed, and creating a waiting period is a big problem. Under this circumstance, the wall supplier can complete the construction of the wall work without worrying about the work schedule of the joiner, and then the bottleneck will be eliminated if the joiner can complete the work without problems.

  In addition, when a wall supplier has a plurality of sites, since the construction period of each site is determined, the construction site and process cannot be easily changed. Therefore, if the door frame attached to the wall opening before the change can be used, all processes can be matched with the arrival of the partition wall members. There will be no extra workers and no waiting period, and it will be possible to work smoothly and solve the problem.

In order to improve the conventional flow, it is necessary to make the construction work of the joinery contractor and the construction work of other construction contractors related to the lightweight steel partition wall independent. The joiner contractor is not related to the construction work of the wall builder, and is not affected by the progress of the work. In any construction situation, it can be solved by using an attachable entrance steel joiner. For lightweight steel partition walls, steel joiner construction methods before board pasting and steel joiners after board pasting have already been proposed, but they can be attached regardless of the progress of lightweight steel partition walls. There is no proposal regarding the construction method of steel joinery.

The present invention easily attaches a non-welded dry assembly type door frame structure that can be mounted without being affected by the progress of the construction of the lightweight steel wall and has good workability. The purpose is to provide a possible construction method.

In the construction of lightweight steel partition walls for buildings, when different contractors make progress while crossing work, the strut members between slabs, frame positioning boards and L To develop a simple installation method for non-welded dry assembly type door frame structure of door frame body that can be constructed regardless of the progress status of lightweight steel partition wall opening using a clamp fixture It is aimed.
