In this embodiment, the height position of the small beam 61 can be changed by changing the engagement position of the engagement claw 654 on the small beam 61 side with respect to the engagement holes 14 and 24 on the columns 1 and 2 side. For this reason, by adjusting the mounting height of the small beam 61 according to the height of the indoor device to be installed, the indoor device can be fixed to the small beam 61 at the optimum height position, and the indoor device is stabilized. In this state, it can be firmly fixed.

  Furthermore, since the beam 61 can be attached at any position between the columns 1 and 2, the beam 61 can be attached almost certainly according to the installation location of the indoor equipment. Therefore, the indoor device can be securely fixed to the beam 61 regardless of the installation location.

  As described above, according to the frame structure of the present embodiment, the upper beam 4 supporting the upper intermediate beam 6 is engaged with the engagement claw 454 of the gusset plate 45 and either of the columns 1 and 2 is engaged. Since the holes 14 and 24 are engaged and fixed, the height positions of the upper beam 4 and the upper intermediate beam 6 can be freely changed by changing the engagement holes 14 and 24 with which the engagement claws 454 are engaged. Can be changed. That is, since the height position of the upper intermediate beam 6 can be adjusted in accordance with the upper end positions of the both side supports 91, 91 of the experimental table 9, the upper end portion of the experimental table 9 can be fixed at the optimum height position. Therefore, the experimental table 9 can be firmly fixed in a stable state, and higher earthquake resistance can be obtained.

  Further, in this embodiment, as the frame members such as the columns 1 and 2 and the beams 3 to 6 constituting the frame structure, those having a hollow structure having a space continuous in the length direction are used. In a state where the frame members are coupled, the internal spaces of the respective frame members are connected in communication. For this reason, as shown in FIGS. 2 to 4, the cords 76 are exposed to the outside by inserting and arranging cords 76 such as electric wiring cords and cables in the internal space of the frame members 1 to 6 connected in communication. It can arrange | position freely, without making it. Therefore, a desired electrical wiring facility can be obtained reliably without deteriorating the aesthetic appearance. Thereby, for example, an outlet (power source) or an electric switch can be arranged at an appropriate position in accordance with the convenience of the worker, and work efficiency can be improved.

  Further, according to the frame structure of the present embodiment, the floor panel 7 is supported by the lower beam 3 bridged between the lower ends of the columns 1 and 2 via the lower intermediate beam 5. An underfloor space can be formed between the installation surface S below. Therefore, as shown in FIGS. 3 and 5, in addition to the electrical wiring equipment as described above, desired piping equipment, for example, piping 77 such as drainage pipes and water supply pipes can be laid freely in the underfloor space. Convenient laboratory and laboratory can be built.

  Moreover, since the lower beam 3 can change the height position in the same manner as the upper beam 4, the size (height) of the underfloor space can be freely adjusted. Accordingly, an underfloor space suitable for a desired piping facility or the like can be reliably formed, and a more convenient laboratory or laboratory can be reliably constructed.

  Further, in the present embodiment, by engaging the engagement claws 354 and 454 at the ends of the lower beam 3 and the upper beam 4 with the engagement holes 14 and 24 of the columns 1 and 2, the lower beam 3 and the upper beam 4 is fixed to the columns 1 and 2 so that the lower beam 3 and the upper beam 4 can be attached to the columns 1 and 2 simply by engaging or releasing the engaging claws 354 and 454. Or can be removed.

  Furthermore, in the present embodiment, a plurality of engaging claws 354 and 454 are formed at each end of the lower beam 3 and the upper beam 4, specifically, five each, and these five engaging claws 354 are formed. , 454 are all attached to the support holes 1, 24 by engaging them with the engagement holes 14, 24, so that sufficient attachment strength can be obtained, and the lower beam 3 and the upper beam 4 are inadvertently detached. Can be reliably prevented.

  Furthermore, in the present embodiment, since almost the entire area of the gusset plates 35 and 45 fixed to the ends of the lower beam 3 and the upper beam 4 are arranged along the outer peripheral side surfaces of the columns 1 and 2, the lower beam 3 and the mounting posture of the upper beam 4 with respect to the columns 1 and 2 are stabilized, and the lower beam 3 and the upper beam 4 can be fixed in a more stable state.

  Furthermore, in this embodiment, since many engagement holes are provided in the lower beam 3 and the upper beam 4 at predetermined intervals in the length direction, indoor equipment such as the experimental table 9 is fixed at an arbitrary position. be able to.

  Furthermore, in this embodiment, since the upper beam 4 and the lower beam 3 are connected via the indoor device by fixing the upper and lower sides of the indoor device to the upper beam 4 and the lower beam 3, the frame structure itself The strength can be further increased.

  Moreover, in the frame structure of this embodiment, since the upper and lower ends of the both-side supports 91, 91 of the experimental table 9 are fixed, a more comfortable work space can be provided as described in detail below.

  In other words, an experimental bench (work bench) that has two columns on both sides and does not fix the upper end is provided with legs that protrude forward and rearward at the lower ends of both columns, and the entire leg is placed on the floor surface. By installing (fixing), the test bench will not fall forward or backward. However, in such an experimental bench, the legs protruding forward and backward may interfere with the operator's feet and the like, which may hinder the work.

  Therefore, in this embodiment, since the upper and lower ends of the both-side support columns 91, 91 of the experimental table 9 are fixed, the experimental table 9 can be overturned even if the leg portions projecting back and forth are not provided at the lower ends of the both-side support columns 91, 91. Can be surely prevented. Thus, it is not necessary to provide the leg part which protrudes back and forth in the lower end of the experiment stand 9, and it can prevent that an operator's leg | foot interferes with this leg part. Therefore, a more comfortable work space can be obtained and work efficiency can be further improved.
