The holes are the same as the holes 7a, but for convenience, the reference numerals are distinguished.

As described above, the fire receiving material 1 (the first and second portions 2 and 3) is, for example, a conventional fire receiving material 1.
Compared to 00, the number of members is small and the construction is minimal, so that it has the advantage that it can be made much smaller and lighter than the fire receiving material 100. Therefore, the workability is good because of the light work, and the total number of bolts for fixing the first and second portions 2 and 3 to the protruding portion 20 is relatively small.

Next, the joining structure of the striking beams 21, 21 using the striking material 1 having the above-described structure will be described.
First, as shown in FIG. 3, a belly 20 is provided on a retaining wall (not shown) so that its longitudinal direction is horizontal. Further, one ends of the cutting beams 25,...

The parts 2 and 3 of 2 are provoked and temporarily fixed to 20. At this time, since the fire striking material 1 has a divided structure divided into the first part 2 and the second part 3, the first part 2 and the second part 3 are separately provoked. Since the temporary fixing work can be performed temporarily, the temporary fixing work becomes relatively light work, and the positioning and the like are easy, so that the workability is good. In this temporary fixing stage, the interval between the first and second portions 2 and 3 is reduced. Further, the other ends of the striking beams 21 and 21 are fixed to the cutting beams 21 and 21 via the joining members 26 and 26. In this state, the end face of one end of the striking beams 21, 21 is
The first and second portions 2, 3 face the receiving surfaces 7, 17 respectively.

Next, the temporarily fixed first and second portions 2 and 3 are moved along the longitudinal direction of the fixing holes 9a,.
By sliding along the longitudinal direction of the bulging 20 and adjusting the position of the first and second portions 2 and 3 in the longitudinal direction of the bulging 20, the end surfaces and the receiving surfaces of the striking beams 21 and 21 are adjusted. 7 and 17 are brought into close contact with each other. Thereby, the receiving surfaces 7, 17

As a result, the first and second portions 2, 3 are maintained at a predetermined interval, and the receiving surfaces 7, 17 to which one ends of the striking beams 21, 21 are fixed can be made constant.
Therefore, suitable joining properties between the fire striking material 1 and one ends of the fire struts 21 and 21 can be obtained. As described above, the operation for obtaining the suitable joining property between the fire striking material 1 and one end of the fire struts 21 and 21 is performed by adjusting the distance between the first portion 2 and the second portion 3 to the distance adjusting material.

Since the installation positions of the first and second portions 2 and 3 can be adjusted in the longitudinal direction of the prong 20, the first and second portions 2 and 3 can be adjusted along the longitudinal direction of the prong 20. By moving the portions, the receiving surfaces 7, 17 and one ends of the pair of fire beams 21, 21 are brought into close contact with each other, and then one ends of the fire beams 21, 21 can be fixed to the receiving surfaces 7, 17. . Therefore, suitable joining of the fire striking material 1 and the fire struts 21 and 21 becomes possible. At this time, both the first and second parts 2 and 3 are prone to bulge the first and second parts 2 and 3 to the bulge 20 and to fix them to the fastener 20 by fastenings such as bolts. 20 fixing holes 9 which are long holes in the longitudinal direction
, the positions of the first and second portions 2, 3 can be adjusted in the longitudinal direction of the bulge 20 along the fixing holes 9a,.

Further, the receiving surfaces 7, 17 of the first and second parts 2, 3 are fixed to one end of each of the striking beams 21, 21 with fasteners such as bolts. , 17a,..., Which are long holes for performing the operation, the position of one end of the striking beams 21, 21 and the receiving surface 7.

Is set larger than the fixing holes 9a,. Thus, the fixing surface 19 can be installed on the prongs 20, 20 provided at intervals close to the vertical direction. Therefore, the fire receiving member 50 can be more stably provoked and fixed to the 20, 20.

<Modification 2> In the above embodiment, an example was shown in which the spacing adjusting member 30 made of a steel plate or the like was used as the spacing adjusting means. In combination with the adjusting member 30, a biasing means such as a flat jack (manufactured by Far East Steel String Concrete Promotion Co., Ltd.) may be used.

As shown in FIG. 5 (a), the flat jack 40 has supporting plates 41, 41 for urging the object to be energized, and expandable and contractible disposed inside the supporting plates 41, 41. It is roughly constituted by a part 43, intervening parts 42, 42 interposed between the elastic part 43 and the supporting plates 41, 41, an injection pipe 44 for performing high-pressure injection into the elastic part 43, and the like.
