Description

[Detailed description of the invention] This invention relates to a frame device for floor frames of prefabricated buildings, which ensures that the combination of floor frame materials at the corner joints of rectangular floor frames that serve as the foundation of the building is solid and does not become distorted. The purpose is to serve as a framework.

Conventionally, for floor frames of this type of prefabricated buildings, the ends of four formwork materials bent into various shapes are cut diagonally, and the diagonally cut ends are butted and joined, or the diagonal Means for connecting the notches with each other by providing a planar step-like notch at the cut end, for example, Jikko Sho 54
-The one described in Publication No. 10724 was adopted.

However, with such a method, since the joints are joined only between the cut surfaces, there is a risk that the joint members will be twisted in the vertical direction at the frame corner joints, and the frame will be distorted.

In view of the above-mentioned drawbacks, the present invention has devised a frame means in which parts of the joining ends of both members are vertically overlapped and joined so that the frame is not distorted.

An embodiment of the present invention will be explained with reference to the drawings.
Fig. 1 is a perspective view showing the main parts of the frame of the present invention from inside the frame, and Fig. 2 is an exploded perspective view thereof, in which 1 is a side frame, 2 is a front frame that also serves as a sill, and 3 is a corner post. ,4
5 shows the connector at the corner of the frame, 5 the seat plate, and 6 and 7 the husband and wife vaults.

The side frame 1 is made of a shaped material bent to have a convex cross section, and has a raised part 1a projecting along the longitudinal direction of the central part of the upper surface, and a raised part 1a extending from both the inner and outer sides of the raised part 1a. The inner low step part 1b and the outer low step part 1c are formed into a substantially symmetrical shape so that the width of the outer side is slightly wider than that of the inner side,
At the front end of this side frame, the outer low step portion 1c is made longer;
The inner low step portion 1b is shortened and each end portion is cut diagonally so that each step has a planar step shape.

Further, the front frame 2 which also serves as a sill has a door sliding groove 2d and its front edge 2e extending to the front surface of a formwork having the same convex cross section as the side frame 1, and has both left and right ends. is cut perpendicular to the longitudinal direction.

Furthermore, the corner post 3 has its outer corner shaped like an arc, and has right-angled bent pieces 3b, 3b bent inward from both outer surfaces 3a, 3a which are bent in a right-angled direction, and the inner edges thereof. 3c toward the outer surface 3a, and both inner edges 3
It is curved with an opening between c and 3c, and at the lower end, both bent pieces 3b and 3b and both inner edges 3c and 3c are formed.
and are notches, and both outer surfaces 3a, 3 of the remaining notches
Vault insertion holes 3d, 3d are provided in a.

Furthermore, the connector 4 at the inner corner is formed by folding upward the surfaces along the two outer sides that sandwich the right angle of the quadrilateral plate to form rising fixing surfaces 4a, 4a that are perpendicular to each other in plane. In addition to providing vault insertion holes 4b, 4b, an anchor vault insertion hole 4d is provided in the center of the plane portion 4c.

Furthermore, the seat plate 5 has an inner side portion 5a of a slightly wider quadrilateral plate protruding inward from the end of the front frame 2, and an outer side portion 5a.
b is fixed to the lower surface of the front frame, and an anchor vault insertion hole 5c is provided at the inner end corner so as to coincide with the anchor vault insertion hole 4d of the connector 4.

The structure of each member in the present invention is as described above, and to explain the means of combining each member, first, when joining the front end beveled part of the side frame 1 at one end of the front frame 2, The central high step part 1a at the front end of the frame is placed and overlapped on the inner low step part 2b of the front frame 2, and the step part 1
The cut end surface of a is brought into contact with the inner surface of the front frame high stage part 2a, and the cut end surface of the inner low step part 1b is brought into contact with the inner surface of the front frame inner low step part 2b, and the cut end surface of the high step part 1a protrudes from the cut end surface of the front frame high step part 2a. The outer piece 1a' that has been
and the inner edge of the upper surface of the lower step part 1c is brought into contact with the cut end surface of the outer lower step part of the front frame 2, so that the ends of both frames are joined together, and then the inner corner of the joint part Place the connecting tool 4 on the seat plate 5, and bring the fixed surfaces 4a, 4a of the tool into contact with the inner surfaces of the side frame and the front frame, and connect the front frame and the side frame with the vault 6. Screw it onto the inner surface, fit the notch at the lower end of the corner post 3 into the outer corner of the same joint, and screw it onto each outer surface of the side frame and front frame with the vault 7, thus forming the joint between both frames. At the other end of the front frame, the front end of the side frame is joined and connected in the same manner as described above to form a frame.

The frame structure of the present invention is as described above, in which the ends of the central high step of the side frame overlap onto the inner low step of the front frame at the corners of the frame body, and the front end surface of the high step overlaps with the inner low step of the front frame. The two high steps are perpendicular to each other by contacting the inner surface of the high step.
The front end surface of the inner low step part of the side frame abuts and perpendicularly intersects with the inner surface of the inner low step part of the front frame, and furthermore, the outer piece 1a' protruding from the cut surface of the high step part of the side frame is connected to the high step part of the front frame. In such a manner that the inner end of the upper surface piece of the outer lower step part of the side frame abuts the cut end surface of the outer lower step part of the front frame, as well as the cut surface,
The outer surface of each step of the side frame comes into contact with the cut end surface of the front frame,
Since the front end surface of each step of the side frame is in contact with the inner surface of each step of the front frame, each step of both frame members is in contact with both the inner and outer surfaces of the mating member, and a part of the high step part of the side frame is in contact with the inner surface of each step of the front frame. Since the joint is vertically overlapped with the lower part of the mating material, the joint becomes a three-dimensional joint, so there is no twisting in either the vertical or horizontal direction, and the combined frame The body is not distorted.

In addition, by screwing and fixing from both the inner and outer corners of the frame with the connectors 4 and the corner posts 3 from both the inner and outer sides, the connection of the frame corner parts is reliably and firmly, and the assembly building can be easily assembled. Build a solid foundation for the foundation of
