Description of the Related Art The ceiling of a prefabricated house is constructed by suspending a foundation made of wooden squares in a lattice shape on a ceiling beam, nailing the periphery of the ceiling with a nail, and then nailing a ceiling plate under the foundation. It has been constructed by. However, the use of a metal base has recently been considered due to the complexity of manufacturing, the high price of the wooden base, and the increasing movement of conservation of wood resources. However, in order to assemble a metal base using a grooved steel instead of a wooden square in the form of a lattice like a conventional wooden base, a large number of connection members are required for assembly. There is a problem that assembling to a substrate or a substrate becomes complicated. [0004] In view of the above, the present invention provides a metal ceiling base member that can be manufactured without using a connecting member. According to the present invention, there is provided a ceiling base member comprising two male / female structures, each of which has a male and female structure in which respective bottom walls can be fitted to each other, in parallel so that the groove sides face each other. And the opposite side walls of both channel members are connected by a plurality of bars smaller than the groove width of the channel members, and the opposite side wall of one channel member is reduced in number.
A grid provided with engaging pieces bent in one side wall direction at both ends and two second channel members are arranged in parallel so that the groove sides face each other, and the width of the grid is set to the groove side of each side wall. At substantially equal intervals, project the protrusions in the longitudinal direction with respect to the center plane between the two second channel members.
A plurality of ridges are provided so as to be symmetrical with each other, and a cutout for inserting a lattice is formed on one side of each projection. The two channel members of the lattice have a male and female bottom wall. When a plurality of lattices are arranged in the same direction so that the channel members are adjacent to each other, the adjacent channel members are fitted to each other. It is possible,
If one of the fitted channel members is fixed, the other can be supported. In addition, both grooved members of the lattice have grooves on the opposite side wall.
Since both ends are connected by a bar narrower than the width of the groove of the mold , both ends of the opposite side wall can be inserted into the groove from the notch hole of the ridge, and the engaging pieces provided at both ends engage with the projections Can be done. Further, since the projections are substantially equal to the width of the lattice, if the engaging pieces of the first lattice are engaged with the projections, then the second lattice is fitted with the first lattice. , 2
The engagement piece of the second lattice can be engaged with the projection. [0007] Therefore, after the two ridges are arranged horizontally and parallel to each other so that the positions of the projections coincide with each other, and the distance between the two grooves is adjusted to the length of one of the groove members of the lattice. ,
Insert the both ends of both channel members into the groove from below the cut holes with the lattice with the channel members left and right, and move the engaging piece of one channel member to the projection side, The projections can be engaged and the grid can be hung on the ridge receiver. Since the other channel member of the grid does not hang on the ridge receiver, the first grid hangs the other channel member on a girder or the like by a known method. For the second and subsequent lattices, one channel material is inserted into adjacent cut holes, and the other channel material is inserted into the same hole as the cut hole into which one channel material of the first lattice is inserted, and the other of the lattices is inserted. If the channel member is fitted into one channel member of the first grid and the engaging piece of one channel member is engaged with the projection, the grid can be continuously suspended. 1 to 7 show an embodiment of a ceiling base according to the present invention. The lattice 1 shown in FIGS. 1 and 2 has two channel steels 2 having the same length and the same groove width. , 2a are arranged in parallel such that the sides of the grooves 3, 3a are opposed to each other.

Since 11a is symmetrical as described above, the case of the grooved steel 2 of the lattice 1 and the ridge receiver 11a is the same as in FIGS. That is, the interval L 1 between the protrusions 15 in the field receiver 11.
Is approximately equal to the width L of the lattice 1, and the distance L 2 between the protrusion 15 and the adjacent side end of the cut hole 16 is approximately equal to the depth from the tip of the opposite side wall 9 of the channel steel 2 to the bottom of the ridge 7. When the opposite side wall 9 of the channel steel 2 is inserted into the groove 14 from the cutout hole 16 and the lip 10 is engaged with the projection 15, the inside of the ridge 7 becomes one side as shown in FIG. It is designed to ride on the side wall 13. The width of the cut hole 16 is wider than the depth from the tip of the side wall 9 on the opposite side of the channel steel 2 to the bottom of the ridge 7, and the distance L 3 between one side ends is also substantially equal to the width L of the lattice 1. FIG. 8 shows the lattice 1 and the field receivers 11,11.
