[0010]
[First embodiment]
1 is a longitudinal sectional view, FIG. 2 is a transverse sectional view, and FIG. 3 is a partially enlarged view of FIG.
[0011]
In the first embodiment shown in FIGS. 1 to 3, the pillar 1A and the beam 3A are joined to each other, and the first and second receiving protrusions 2 provided on the side surface 1A ′ of the pillar 1A are provided. Reference numeral 2 'denotes a structure in which a bolt rod 5 is passed through a through-hole 4 provided in the pillar 1A, a tip portion thereof is projected from the side surface 1A', and a nut material 6 is screwed and tightened to the tip portion. Each of the receiving protrusions 2, 2 ′, 2 ′ has a pair of second receiving protrusions 2 ′, 2 ′ directly below the uppermost receiving protrusion 2, that is, the first receiving protrusion 2. The first latching rod 7 or the second latching rod 7 ′ is placed (latched) in the arrangement relationship arranged in series in the vertical direction, and fitted to the beam 3A. .
[0012]
The nut member 6 is composed of a screw cylinder 6a and a head 6b provided at one end of the screw cylinder 6a. The head 6b is a cone that gradually expands the diameter of a portion on the screw cylinder 6a side from one end on the screw cylinder 6a side. A tapered portion 2a provided in a trapezoidal shape, and a flange portion 2b disposed between the tapered portion 2a and a tip portion 6b '' having a bolt head shape are provided.
[0013]
A washer 8 (consisting of a circular plate having a diameter larger than that of the flange 2b) is interposed between the receiving protrusions 2 and 2 '(nut material 6) and the side surface 1A' of the column 1A. When the material 6 is screwed and fastened to the tip of the bolt rod 5 protruding from the column 1A to obtain (configure) the receiving protrusions 2 and 2 ', the nut material 6 is destroyed on the side surface 1A' of the column 1A. To prevent it from entering. The washer 8 ′ interposed between the head of the bolt rod 5 and the column 1 similarly prevents the head of the bolt rod 5 from collapsing into the column 1 </ b> A.
[0014]
The beam 3A has a diameter sufficient to engage and store the first and second receiving protrusions 2 and 2 ′ and the washer 8 at the center of the end surface 3A ′ that contacts the side surface 1A ′ of the column 1A. A longitudinal groove 9 having a width is provided.
[0015]
The longitudinal groove 9 has a small-diameter portion 9b provided in a slit (slit) shape along the longitudinal direction of the beam 3A on both sides of the large-diameter portion 9a on the end surface 3A ′ side and the back wall 9a ′ of the large-diameter portion 9a. 9b, and a pair of reinforcing plates 10 and 10 are installed in the longitudinal groove 9 to reinforce the ends of the beam 3A, and the latching rods 7 and 7 'are formed on the receiving protrusions 2 and 2'. When latched (placed), the load of the beam 3A loaded on the latch rods 7 and 7 'is dealt with.
[0016]
The reinforcing plate 10 is a flat plate made of steel, and one to three so as to correspond to the receiving protrusions 2 or 2 'provided on the column 1A side on one side (on the large diameter portion 9a side of the longitudinal groove 9). A pair of first through holes 11, 11, 11, 11, 11, and 11 and three second through holes 12, 12, 12 on the other side (on the small diameter portion 9b side of the longitudinal groove 9), respectively. They are provided symmetrically in the vertical direction and are assembled to the beam 3A and the receiving protrusions 2 and 2 'by using the through holes 11 and 12. The reason why the numbers and positions of the through holes 11 and 12 are made symmetrical is to reduce the manufacturing convenience and inventory management cost of the reinforcing plate 10 and the convenience in handling (because directionality is free). .
[0017]
The side surface of the end portion of the beam 3A is positioned so as to coincide with the upper one of the first through holes 11 and 11 of each set provided on one side of the reinforcing plate 10, and the longitudinal groove The first insertion holes 13, 13, 13 are provided so as to intersect with the large-diameter portion 9 a, and the lowest first insertion hole 13 in the first insertion holes 13, 13, 13 (for convenience, reference numeral A lower first through-hole 11 (for convenience) that forms a pair with the first through-hole 11 (shown by reference numeral 11a for convenience) corresponding to the fitting insertion hole 13 (13a) is provided on the lower side. The first reinforcing insertion hole 13 is provided at a position coinciding with the position of the reinforcing plate 10 at the rear end side of the end of the beam 3A. The second fitting insertion hole 1 is formed so as to intersect with the small diameter portion 9b of the longitudinal groove 9 at a position coinciding with the second through holes 12, 12, 12 provided on the other one side. , It is then laterally disposed the 15, 15.
[0018]
The reinforcing plate 10 is arranged such that one side of the second through hole 12 side is arranged in the small diameter portion 9b of the vertical groove 9 and the other side of the first through hole 11 side is arranged in the large diameter portion 9a. The first through hole in which the second through hole 12 on the reinforcing plate 10 side and the second fitting insertion hole 15 on the beam 3A side are made to coincide with each other, and the assembly rod 16 made of drift pins is made to coincide with each other. 11 and the first insertion hole 13 are respectively inserted into the uppermost ones of the first retaining rods 7 made of drift pins and fixed to the end of the beam 3A. An engagement gap 19 composed of the reinforcing plates 10 and 10 is formed, and is arranged by the first latch rod 7 positioned at the uppermost position so as to be orthogonal (cross) the engagement gap 19, and the beam 3A Can be joined to the pillar 1A having the first and second receiving protrusions 2 and 2 '(generally, in this state, the factory is shipped to the site To transport).
[0019]
Then, the first and second receiving protrusions 2 and 2 ′ protruding from the column 1 </ b> A and the washer 8 are relatively engaged with each other in the engagement gap 19 between the reinforcing plates 10 and 10 of the beam 1 </ b> A. When the beam 3A is lowered along the side surface 1A 'of the column 1A, the first hook 7 placed on the upper side of the engagement gap 19 is placed on the tapered portion 2a of the uppermost first protrusion 2. Due to the inclination, the first latching rod 7 moves downward while moving in the direction of the column 1A, and the first latching rod 7 can be automatically latched and joined to the receiving protrusion 2 so that the beam 3A is connected to the column 1A. The beam 1A is supported by the uppermost first protrusion 2 via the first latching rod 7 and temporarily joined to the column 1A. In this state, the washer 8 is engaged with the engagement gap 19. In other words, a stable temporary joined state of the beam 3A to the column 1A can be obtained by interposing between the reinforcing plates 10 and 10. In order to obtain this stable temporary joining state, in the embodiment, the center of gravity of the beam 3A changes around the contact point (load point) with the tapered portion 2a (the receiving protrusion 2) of the first latching rod 7. Therefore, the reinforcing plate 10 comes into contact with the washers 8 and 8 'to restrict the movement. Therefore, the diameters of the washers 8, 8 'and the width of the gap 19 should be as close to the same diameter as possible if the complexity of the descent operation is ignored.
[0020]
If the largest diameter portion of the receiving protrusions 2 and 2 ′ (the flange portion 2b in the embodiment) is made larger than the diameter of the washers 8 and 8 ′, the outer edges of the portions close to the reinforcing plate 10 are engaged. It will be engaged in the joint gap 19 and the stable temporary joining state will function.
[0021]
Then, when the other first through hole 11 and the second fitting insertion hole 13 that are in communication with each other are driven into and inserted into the second hooking rod 7 ′, the second hooking rod 7 ′ becomes the second protrusion 2. ′ 'Taper portion 2a (due to the inclined shape of the taper edge), and as a result, the beam 3A is pulled in the direction of the column 1A, and the second latching rod 7 ′ is laterally mounted and fixed to the beam 3A. It is arranged at a position where it is supported by the second receiving protrusion 2 ', and the load of the beam 3A is applied to the receiving protrusion 2' so that the load resistance strength can be obtained.
[0022]
In addition, the drift pin is inserted into the lowest first through hole 11 (indicated by reference numeral 11b) and the lowermost first fitting insertion hole 13 indicated by reference numeral 13b before and after the driving operation of the second retaining rod 7 '. The beam 3A may be joined and fixed to the column 1A by driving and engaging the locking rod 18 configured as described above, and then the second latching rod 7 'may be driven.
[0023]
Note that the number of the second receiving protrusions 2 ′ (the corresponding first through holes 11 and the first fitting insertion holes 13) may be appropriately selected, and an appropriate number may be selected and used. Further, the second latching rod 7 'may be used in correspondence with all or appropriate ones of the respective second protrusions 2'. In the embodiment, the locking rod 18 is locked to the receiving protrusion 2 'at the lowest position, but the locking rod 18 is attached to the other receiving protrusions 2 and 2' as in the embodiment. Of course, it may be arranged.
[0024]
[Second Embodiment]
4 shows a longitudinal sectional view, and FIG. 5 shows a transverse sectional view. In the second embodiment shown in these drawings, the upper end surface 3B ′ of the climbing beam 3B is arranged on the side surface 1B ′ of the ridge beam 1B, and the lower end surface 3B ″ is arranged. The end of the climbing beam 3B is joined to the side beam 1C 'of the eaves beam 1C so that the ridge beam 1B is joined to the eaves beam 1C. The present invention is carried out at the joint with 1C.
[0025]
In this second embodiment, the first and second protrusions 2 and 2 ′ are nuts at the ends of the bolt rods 5 in which the first embodiment penetrates the pillars 1 </ b> A corresponding to the ridge beam 1 </ b> B and the eaves beam 1 </ b> C. While the material 6 is screwed together, the head of the bolt rod 5 is made to have a hexagonal tip 6b ″ and a leg rod similar to the nut material 6 (on the screw cylinder 6a of the first embodiment). The first and second protrusions 2 and 2 'are provided with a flange portion 2b between a tapered portion 2a provided with a truncated cone shape gradually increasing in diameter from one end on the leg rod side. The remaining point is the same as that of the first embodiment as shown by the same reference numeral, except that the washer 8 formed separately from the bolt rod 5 of the first embodiment is integrated with the bolt rod 5. It is. That is, the reinforcing plate 10 and the first hook 7 are assembled to the upper and lower ends of the climbing beam 3B side as in the first embodiment, and descend along the side surfaces 1B 'and 1C' of the ridge beam 1B and the eaves beam 1C. Then, after the first hooking rod 7 is hooked on the first receiving protrusion 2 and temporarily joined, only one piece is used, corresponding to the lowermost second protrusion 2 'of the first embodiment. In the same manner as in the first embodiment, the second protrusion 2 'is combined with the second hooking rod 7' and the locking rod 18, so that the climbing beam 3B can be joined to the ridge beam 1B and the eaves beam 1C. .
[0026]
The bolt rod 5 is passed through the through hole 4 provided in the ridge beam 1B and the eaves beam 1C, and the nut 6 ″ is screwed and tightened to the tip via a washer 8 ″. A commercially available bolt can be used simply by preparing a bolt, whereas in this second embodiment, the head side must use a specially shaped bolt rod. Of course, it may be applied to the embodiment, and the combination of the bolt rod 5 and the nut material 6 of the first embodiment may be applied to the joining of the climbing beam 3B of the second embodiment. .
[0027]
In addition, the reinforcing plate 10 has a slightly rhombus shape (therefore, the positional relationship between the through holes 11 and 12 is not vertically symmetrical), because this corresponds to the inclination of the climbing beam 3B. Of course, the reinforcing plate 10 on the side of the ridge beam 1B and the reinforcing plate 10 on the side of the eaves beam 1C are of the same shape, and the number of assembling rods 16, the second retaining rods 7 ', or the locking rods 18 are the same. As described above, as in the embodiment, it is not necessary to limit to the illustrated embodiment.
[0028]
Incidentally, in each of the first and second embodiments, the first retaining rod 7 is assembled in advance on the side of the beams 3A and 3B (the other one of the shaft assemblies), and the beams 3A and 3B are attached to the columns 1A and 3A. The beam is lowered along the master beam 1B (one shaft assembly) to be hooked on the first receiving protrusion 2 but the beams 3A and 3B are raised along the beam 1A. After the receiving protrusions 2 and 2 'are relatively engaged in the longitudinal grooves 9 of the beams 3A and 3B, that is, between the reinforcing plates 10 and 10, the first latching rod referred to in the first and second embodiments is used. 7 or the second latching rod 7 'may be fitted into the beams 3A and 3B using the holes 11 and 13 and latched on the receiving protrusion 2 or 2'. By adopting such an assembling order, the beams 3A and 3B can be moved upward to be assembled to the column 1A or the building beam 1B. For example, an existing existing between the columns 1A (one shaft assembly) When the horizontal member is replaced, the horizontal member can be replaced regardless of the upper side of the existing horizontal member (for example, an upper floor).
[0029]
【The invention's effect】
Since the present invention is configured as described above, it is possible to provide a joining device that can be easily joined.
[0030]
In addition, even if the weight of the other one of the shaft assemblies is loaded on the hook by hooking on the receiving protrusion, load resistance can be obtained due to the presence of the reinforcing plate. It can be arranged as close as possible to the end face of the assembly, and as a result, the protruding amount from the side of the shaft assembly of the receiving protrusion provided on one of the shaft assembly can be reduced. . By reducing the protruding amount, the receiving protrusion itself can be reduced in size, and as a result, the vertical groove of the other shaft assembly that engages the receiving protrusion can be reduced in diameter. It is possible to prevent the strength of the shaft assembly from being lowered, and to provide a durable shaft assembly joining apparatus with a simple structure (and hence inexpensive).
