Description

[Detailed description of the invention] This invention relates to a floor connection device for prefabricated buildings, which simplifies the assembly of the floor and also ensures the connection between the floorboards and the floor frame and between each adjacent floorboard. The purpose is to create a solid floor that will not easily warp or fall off.

For this purpose, both ends of the middle connecting rod, which is spanned between the intermediate parts of the front and rear floor frames that are installed opposite each other, are hooked to both floor frames, and the joining edge of each floor plate connected between the two floor frames is connected to the middle connecting frame. The floorboards are inserted into the upwardly directed concave grooves so as to be closely overlapped, and each outer edge of the floorboards is formed with a step lower than the floor surface along the floor edge, and the pillars and wallboards are placed upright on this low step. In this way, the outer edge of the floor plate was configured to serve as a floor side frame, and the connection between the floor members was ensured by combining both the front and rear floor frames with the middle connecting rod and the floor plate using both engagement and screwing. .

To explain the drawings of one embodiment of the present invention, Fig. 1 is a perspective view showing the assembled state of each member of the floor section in the present invention, in which 1 is a floor plate, 2 is a rear floor frame, and 3
is a threshold and front floor frame, 4 is a push plate on the floor board, 5 is an entrance support insertion hole drilled on the front floor frame, 1b is a low step part that doubles as a floor side frame, stepped along the outer edge of the floor board, 6 is a corner support, 7 is a middle support, 8 is an entrance support, and 9 is a vault in which the push plate 4 is fastened together with a floor plate onto a floor frame.

Figure 2 shows the shape and arrangement of each member disassembled from the previous figure. The numbers for each member are the same as in the previous figure, but they are located below the floorboard 1 in the previous figure and cannot be seen. The middle tsunagi dan is displayed as 10.

The floor plate 1 has an inner edge bent downward and inward to form an L-shaped bent piece 1a whose height matches the depth of the concave groove 10a of the middle tether. A U-shaped low step part 1b lower than the surface is curved, and the corner posts 6, middle supports 7, and wall boards on this low step part 1b are made to stand upright, and the outer edge of this floor board also serves as a floor side frame. Both the front and rear ends of the floorboard are appropriately cut out to form long and short parts for convenience in combination with other members. In the diagram, two floorboards are installed on the left and right, but depending on the length of the frontage of the building, an intermediate connecting frame and a floorboard can be added to the middle between the front and rear floor frames, and the additional floorboards Both side edges of the above-mentioned floor plate 1
Any number of pieces can be formed in the same shape as the bent piece 1a on the inner edge of the piece and can be arranged in series. In addition, 1c in FIG. 4 is a reinforcing rod attached to the back surface of the floorboard in the front-rear direction.

The upper surface of the intermediate connecting rod 10 is open over the entire length, and a recessed groove 10a is provided, and both edges of the recessed groove are bent in opposite directions to form a horizontal edge 10b for reinforcement. A pair of downward hooks 10d are provided protruding from both side plates 10c at both front and rear ends. Third
The figure shows the state in which this middle connecting rod engages with the front and rear floor frames.

In addition, the rear floor frame 2 is curved in the shape of a step, and has a high floorboard mounting surface 2a on the front edge and a low step part 2b that serves as a support and wallboard standing surface on the rear edge. A pair of left and right latching holes 2d are bored in the middle of the side surface 2c.

In addition, the front floor frame 3 has a door sliding groove 3b on the rear side of the front edge 3a.
A wall board mounting surface 3c is provided behind it at the same height as the front edge, and a rear edge 3d is stepped slightly higher than the front edge, and this rear edge 3d is used as a mounting surface for the front end of the floorboard. A pair of left and right latching holes 3f are provided in the middle part of the inner surface 3e of the rear edge, facing the latching holes of the rear floor frame.

Furthermore, the push plate 4 is bent into an L shape so as to sandwich and crown the end of the floor plate on each floor plate mounting surface of the front floor frame and the rear floor frame, and has a plurality of vault insertion holes 4b on the horizontal surface 4a. There is.

The corner support 6 has an open inner corner and is curved into a square prism shape, the middle support 7 is a square pipe, and the entrance support 8 has an inner corner opened and curved into a square prism shape.

The procedure for assembling and configuring the floor section according to the present invention is to install the front floor frame and the rear floor frame side by side, span the middle connecting rod 10 between the middle parts of both floor frames, and hook the hooks provided at both ends of the rod. 10
d into the hooking holes on the inner surfaces of both floor frames to connect both floor frames, and then lay floorboards 1... across both floor frames, and bend the downwardly bent pieces at the joint edges of these floorboards. are closely overlapped with each other and inserted into the groove on the middle tether, the front and rear ends of the floor board are placed on the inner edges of both the front and rear floor frames, and then the push board is placed on the end of the floor board. crowned with
By tightening the bolts to the floor frame, each floor plate is connected and laid on the floor frame, and the entire floor is constructed at the same time.

Since the present invention has the above-described configuration, it has the following effects.

Since both ends of the middle connecting beam were engaged with the intermediate parts of both the front and rear floor frames using the hook parts, the bridge was constructed by connecting the middle parts of both floor frames with this middle connecting beam, and the spacing between the front and rear floor frames was kept constant. to prevent both floor frames from opening and the floor from collapsing.

In addition, both front and rear ends of the continuous floorboards were placed on both the front and rear floor frames, a push rod was mounted on top of the floorboards, and both were bolted to each floor frame with a vault, so the floorboards were not detached from the floor frames. A solid floor can be constructed without tilting or tilting.

In addition, since the downwardly bent pieces with a height that matches the depth of the groove formed at the joint edge of each consecutively installed floorboard were closely overlapped and inserted into the groove of the middle connecting frame, both joint edges The lower end is supported on the bottom of the groove in the groove of the middle connecting beam, and it is also held between the groove side plates from both sides, so there is no gap between the joints of adjacent floor plates, and the joint is lower. It is strong against vertical loads because it does not collapse.

Furthermore, by forming step portions that also serve as floor side frames along the outer edges of both the left and right floor plates and connecting the front and rear floor frames with the floor plates, the entire floor can be reliably and firmly assembled. The connection between the floor frame and the floor board is also reliable.

In this way, each of the connection means, such as the engagement between the front and rear floor frames and the middle connecting beam, the screw connection between the floor frame and the floorboards, and the connection between each connected floorboard by the middle connecting beam, work together to ensure that there is no distortion or separation. Since the floor part can be constructed, the assembly means such as Naoyuki is simple, and there is no wastage of members, it is advantageous in terms of workmanship, and the intended purpose can be achieved.
