The utility model provides an external channel is used to brick-concrete structure cable pit, this channel is applied to the ditch end and is the concrete, the side wall is the cable pit of brick-concrete structure, this channel includes the channel body, first mounting and second mounting, first mounting is connected the channel body and the ditch end, the second mounting with the channel body and with the outer ground of side wall, the installation of current channel and cable pit has been realized, need not channel and side wall lug connection, be convenient for be applicable to the brick-concrete structure cable pit that the side wall bearing capacity is not enough.

The specific embodiment is as follows:

example 1, as shown in fig. 1 to 4, an external channel for a cable trench of a brick-concrete structure includes a channel body 2, a first fixing member 1, and a second fixing member 3. The channel body 2 is arranged vertically along the side wall 4. The first mounting 1 is connected to channel body 2 lower extreme, and the other end of first mounting 1 is connected with the ditch bottom 5 of cable pit, realizes the fixed of channel body 2 lower extreme. The second fixing piece 3 is connected to channel body 2 upper end, and the other end of second fixing piece 3 extends towards the one side that channel body 2 was kept away from to side wall 4. The second fixing piece 3 is arranged at the top end of the side wall 4, and two ends of the second fixing piece respectively extend to two sides of the side wall 4 in a hanging mode. The end of the second fixing piece 3, which is far away from the channel body 2, is provided with a connecting piece, and the connecting piece is fixed with the ground on the side of the side wall 4, so that the upper end of the channel body 2 is fixed. More specifically, the connecting piece adopts a steel chisel 31, and the end part of the second fixing piece 3 far away from the channel body 2 is provided with a through hole in which the steel chisel 31 is arranged. The second fixing member 3 is connected to the upper end of the cable trench by inserting the drill rod 31 into the ground, that is, the upper end of the channel body 2 is connected to the cable trench.

When the external channel for the cable trench with the brick-concrete structure is used, the channel body 2 is vertically placed along the side wall 4. The lower end of the channel body 2 is connected with a first fixing piece 1, and the other end of the first fixing piece 1 is connected with the groove bottom 5. And a second fixing piece 3 is connected to the upper end of the channel body 2, and the second fixing piece 3 is suspended from the top end of the side wall 4 to one side of the side wall 4 away from the channel body 2. And when the second fixing piece 3 is adjusted to enable the channel body 2 to be tightly attached to the side wall 4, the steel chisel 31 is inserted into the ground after penetrating through the through hole on the second fixing piece 3. The two ends of the channel body 2 are connected to the bottom 5 of the cable trench and the ground outside the side wall 4 through the first fixing piece 1 and the second fixing piece 3 respectively, the channel and the side wall 4 are not required to be directly connected, the problem that the bearing capacity of the side wall of the cable trench with the brick-concrete structure is insufficient is solved, and the applicability is stronger.

Further, the first fixing member 1 includes a first fixing plate 11 and a second fixing plate 13. The first fixing plate 11 extends along the length direction of the channel body 2, and the second fixing plate 13 extends along the trench bottom 5, so that the first fixing plate 11 and the second fixing plate 13 form a bent plate structure. The first fixing plate 11 is provided with a mounting hole, and a bolt is inserted into the mounting hole to connect the first fixing plate 11 to the chute body 2. The second fixing plate 13 is also provided with a mounting hole, and an anchor bolt is inserted into the mounting hole to connect the second fixing plate 13 to the trench bottom 5, and the trench bottom 5 is of a concrete structure and is connected and lifted through the anchor bolt to achieve connection stability and reliability. The second fixing plate 13 is not connected with the side wall 4, so that the problem that the side wall is not enough in bearing capacity and is not convenient to fix the channel through the anchor bolt is solved.

As an example of the present embodiment, the mounting hole of the second fixing plate 13 is an oblong hole to compensate for the mounting error.

As an example of the present embodiment, the first fixing plate 11 and the second fixing plate 13 are integrally formed. Be provided with strengthening rib 12 at first fixed plate 11 and second fixed plate 13 junction, promoted the intensity of first mounting 1, guaranteed the connection reliability between channel body 2 and the ditch bottom 5.

Further, the second fixing member 3 includes a third fixing plate 34 and a fourth fixing plate 33. The third fixing plate 34 extends along the length of the channel body 2, and the third fixing plate 34 is also provided with mounting holes. The fourth fixing plate 33 is connected to the upper end of the third fixing plate 34, the fourth fixing plate 33 extends towards one side of the side wall 4 far away from the channel body 2, and the length of the fourth fixing plate 33 is greater than the width of the side wall 4. The through hole of the second fixing member 3 is provided at an end of the fourth fixing plate 33 remote from the third fixing plate 34. When the channel body 2 is fixed, the third fixing plate 34 is attached to the side of the channel body 2 away from the side wall 4, and the third fixing plate 34 and the channel body 2 are connected by passing a bolt through the mounting hole. The fourth fixing plate 33 extends from the top end of the side wall 4 to the other side of the side wall 4, a steel chisel 31 penetrates into the through hole of the fourth fixing plate 33, and the steel chisel 31 is inserted into the ground outside the side wall 4, so that the connection between the upper end of the channel body 2 and the cable trench is realized. The second fixing piece 3 is simple in structure, convenient to connect with the channel body 2 and convenient to connect with the ground outside the side wall 4. Meanwhile, the second fixing piece 3 is not connected with the side wall 4, so that the problem that the side wall is not enough in bearing capacity and is not convenient to fix the channel through the anchor bolt is solved.

Further, the second fixing member 3 further includes a pretensioning plate 32. The pretensioning plate 32 is connected to the lower side of the fourth fixing plate 33 such that the pretensioning plate 32 and the third fixing plate 34 form a snap groove. When installing channel body 2, pretension board 32 and third fixed plate 34 are arranged in the both sides of side wall 4 and channel body 2 respectively, fix in advance between channel body 2 and the side wall 4 like this, reduce the trouble that needs the people to hold up channel body 2 in the installation, and the installation is more simple and convenient. At the same time, it is convenient to install the bolt between the channel body 2 and the third fixing plate 34, and to connect the fourth fixing plate 33 to the ground outside the side wall 4 through the drill 31.

The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without the technical solutions of the present invention, or the present invention can be directly applied to other occasions without the improvements, and all are within the protection scope of the present invention.
