Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention is based on the invention, in which, for example, an inclined beam that constitutes the frame of a roof of a general house, and corner timbers placed along the upper surface of the inclined beam, are used as pillars. Or it relates to an improvement of a beam fixing device for attaching and fixing to a horizontal beam.

[Technical background of the invention and its problems]

Multiple pillars are erected as the frame of a typical house.
Horizontal beams are strung along the upper ends of these columns. Furthermore, a roof is provided above the columns and horizontal beams. It is well known that the frame that constitutes a roof consists of slanted beams that are the ridges, rafters on which roof base materials called nojiboards are placed, and ridgepoles, purlins, and bundles that hold the rafters.

Incidentally, in recent years, even ordinary houses have begun to use metal materials for their frames to increase strength and improve durability. For example, a steel pipe with a rectangular cross section is often used as the column, a steel material with an E-shaped cross section is used as the horizontal beam, and a steel material with a U-shaped cross section is used as the inclined beam. By using a metal material for a part of such a frame, new measures are required for the joint structure between these ends. That is, since the lower end of the inclined beam member is mounted on the upper end of the column, it is difficult to directly attach and fix these parts, so it may be possible to use metal fittings that are convenient for joining and fixing.

Conventionally, the structure is as shown in FIGS. 6 and 7. a is a column made of steel pipes, b is a horizontal beam made of steel, c is an inclined beam with steel members fixed back to back, and d is a column for attaching and fixing the inclined beam c to column a and horizontal beam b. It is a joining hardware. This joining hardware d connects the upper end of column a and the horizontal beam member b.
A fixing part e consisting of a horizontal plate placed on the horizontal plate b and fixed to the horizontal beam b via fixing bolts (not shown); It consists of a vertical plate f that is inclined at the same angle as the inclination angle. The end of the inclined beam c is connected to the vertical plate f of the joining metal fitting d via a fixing bolt (not shown) so that their upper edges are in a straight line. As shown in FIGS. 7 and 8, corner timbers g made of wood are placed on top of these inclined beams c and vertical plates f, and fixed hardware h made of bent thin metal plates are placed at the corners. The wood g and the inclined beam c are pressed against each other from the sides and fixed to each other with fixing devices i such as nails.

By using such a joining hardware d, the end of the inclined beam c can be connected to the column a with the corner timber g placed on it.
Alternatively, it can be connected and fixed to the upper part of the horizontal beam b to obtain the necessary strength.

However, problems remain regarding the means for fixing the corner timbers g. That is, since the fixture i is hit from the side surface of the corner timber g, it is likely to be misaligned with respect to the inclined beam c. Even if the fixing hardware h is applied to both sides of the corner timber g to fix it, the fixing work is done sequentially from one side, making it difficult to find the correct position. Further, when the fixing tool i is applied upward from the lower surface side of the inclined beam c, it is necessary to take an unreasonable posture, which is inconvenient as this work is troublesome.

[Purpose of invention]

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to facilitate and accurately connect and fix the ends of inclined beams and position the corner timbers relative to the inclined beams. The purpose of this invention is to provide a beam fixing device.

[Summary of the idea]

That is, the present invention is for connecting and fixing the end of an inclined beam made by placing corner timbers along the upper surface to the top of a column or horizontal beam, and the upper edge is inclined on the flat fixed part. A positioning fixing plate is erected on both sides of this plate with the same spacing as the width of the corner timber, and the fixing part is attached and fixed to the top of a column or horizontal beam, and the plate is fixed. A tilted beam member is connected to the end, a corner timber is supported at the upper edge, and the corner timber is fitted between positioning fixing plates and attached and fixed from both sides thereof. This is a beam fixing device.

[Example of idea]

Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 1 shows a roof frame of a general house in plan view. In the figure, b... is a horizontal beam material, and c... is an inclined beam material, and the materials used and the positions of each may be the same as the conventional one. The inclined beam c is connected and fixed by a beam fixing device A as shown in FIGS. 2 and 3. In other words, this is a flat fixed part 1
, a plate 2 and positioning fixing plates 3, 3. The fixing part 1 has an area that rests on the upper end surface of the column a and the end of the horizontal beam b, and fixing holes 4a are bored in the peripheral end. Fixing holes 4b are also bored in the horizontal beam b. The plate 2 is erected along a substantially diagonal line of the fixing part 1, and a part of the plate 2 protrudes outward from the fixing part 1, and has fixing holes 4a and 4.
a is drilled. At least the upper edge of the plate 2 is inclined at the same angle as the angle of inclination of the inclined beam c. The above positioning fixing plate 3,
3 are erected on the fixing parts 1 on both sides of the plate 2. The mutual spacing is the same as the width dimension of the inclined beam c and the corner timber g, and they are equally distributed around the plate 2.

Therefore, in order to construct the roof frame, the beam fixing device A is first attached to the upper end of the column a. That is, the fixing part 1 is placed on the upper end surface of the column a and the upper part of the horizontal beam b, and the bolts 5 are inserted into the respective fixing holes 4a and 4b and tightened with nuts 6 to fix them. The plate 2 protrudes toward the inclined beam c. Next, the end of the inclined beam c is joined to the end of the plate 2 and tilted at a predetermined angle, and then bolts are inserted into the fixing hole 4c and the fixing hole 4d provided at the end of the inclined beam c. 5 and tighten and secure with nut 6. In this state, the upper edges of the inclined beam c and the plate 2 are in a straight line with each other. Incidentally, the above-mentioned inclined beam member c is made by fixing steel members each having a U-shaped cross section back to back through a spacer (not shown). A plate 2 is inserted into the gap created by the spacer 2 above.
Although the end portions of the two are inserted and fixed, it goes without saying that they may be directly fixed back to back as in the conventional case. Furthermore, the corner timber g is placed on the inclined beam c. As shown in FIG. 4, when the width directions are properly aligned, the corner piece g is inevitably inserted between the positioning fixing plates 3, 3. Once this longitudinal position is determined, as shown in FIG.
3 from the side to secure each other. All of the above fixtures 7 need only be hit in the horizontal direction, so
You don't have to take an unreasonable posture. At this time, corner wood g
Since the position in the width direction is regulated from both sides by the fixed plates 3, 3, there is no need for it to move, and therefore, the position is always accurate.

[Effect of idea]

As explained above, according to the present invention, it is possible to easily attach and fix the inclined beam members, and also to reliably prevent positional shift when attaching the corner timbers.
