Fig. 1 is a schematic structural view of the present utility model.
Description of the embodiments
The features of the utility model and other related features are described in further detail below by way of example in conjunction with the following figures to facilitate understanding by those skilled in the art:
as shown in fig. 1, the labels 1-6 are respectively indicated as: the pipe comprises an intermediate wall 1, pipe pieces 2, a pre-buried steel sleeve 3, a screw 4, a refractory material filling body 5 and a reserved space 6.
Examples: as shown in fig. 1, the device for connecting a tunnel segment with an intermediate wall in the present embodiment is used to achieve connection between the intermediate wall 1 and the segment 2, and in particular, allows free vertical displacement of the connection position of the wall top of the intermediate wall 1 and the segment 2, but restricts the lateral misalignment of the two.
Specifically, the device in this embodiment includes pre-buried steel sleeve 3 and screw rod 4, and wherein pre-buried steel sleeve 3 is pre-buried in intermediate wall 1, and screw rod 4 sets up on the inner wall of section of jurisdiction 2 through pre-buried or the mode of planting the muscle, and the setting position of screw rod 4 constitutes with pre-buried position of pre-buried steel sleeve 3 and corresponds, forms a set of connection. In this embodiment, along the extending direction of the intermediate wall 1, i.e., the longitudinal direction of the tunnel, a plurality of the embedded steel sleeves 3 may be embedded at a certain distance interval on the wall top of the intermediate wall 1, and screws 4 may be disposed at corresponding positions of the duct pieces 2 one by one, so that an effective connection is formed between the intermediate wall 1 and the duct pieces 2.
As shown in fig. 1, an internal thread connecting section is arranged in the embedded steel sleeve 3, and the internal thread connecting section is matched with an external thread of the screw 4 in a fit manner, so that the screw 4 and the embedded steel sleeve 3 can be connected and fixed through thread matching, thereby connecting the intermediate wall 1 with the duct piece 2 and realizing the limitation of transverse dislocation between the two. A reserved space 6 is further arranged in the embedded steel sleeve 3, and is reserved for adapting to the convergence deformation of the duct piece 2 under the long-term load effect; the reserved space 6 is positioned at the inner side of the internal thread connecting section from outside to inside along the opening direction of the embedded dry sleeve 3, and when the embedded steel sleeve 3 is embedded at the wall top position of the intermediate wall 1, the reserved space 6 is positioned at the lower position of the internal thread connecting section. Once the pipe piece 2 is displaced, the connecting threads between the embedded steel sleeve 3 and the screw 4 are damaged, and the screw 4 can locally slide into the reserved space 6 downwards, so that the safety and reliability of the connecting structure between the pipe piece 2 and the intermediate wall 1 are ensured on the premise of completing convergence deformation.
In this embodiment, the pre-buried steel sleeve 3 is composed of an external steel sleeve and an internal hard plastic sleeve, and the external steel sleeve and the internal hard plastic sleeve are integrated components, namely, the external steel sleeve and the internal hard plastic sleeve are steel materials, and the internal hard plastic sleeve is provided with internal threads, so that the use effect of the pre-buried steel sleeve 3 is ensured, and particularly, the screw connection strength between the pre-buried steel sleeve 3 and the screw 4 is ensured to be controllable, and the screw connection between the pre-buried steel sleeve 3 and the screw 4 is allowed to be broken when the segment 2 is deformed.
As shown in fig. 1, a refractory filler 5 is disposed between the wall top of the intermediate wall 1 and the duct piece 2, and the refractory filler 5 is an integral fireproof blocking partition material adapted to large deformation, preferably, 50% of the compressible deformation is not damaged under the limit working condition, so as to prevent a gap between the intermediate wall 1 and the duct piece 2 due to the reserved deformation space. When the pipe piece 2 deforms to enable the screw 4 to slide into the reserved space 6 locally downwards, the pipe piece 2 applies force to the refractory material filling body 5, and the refractory material filling body 5 is compressed under force, so that no gap is reserved between the intermediate wall 1 and the pipe piece 2 all the time.
In this embodiment, the compressible deformation of the refractory filler 5 is matched with the depth of the reserved space 6 in the embedded steel sleeve 3, that is, the sliding amount of the screw 4 is limited and is consistent with the compressible deformation of the refractory filler 5, so as to avoid the refractory filler 5 from being damaged by excessive acting force when the sliding amount of the screw 4 is excessive.
The embodiment is implemented in specific manner: the intermediate wall 1 is a reinforced concrete structure, can be a prefabricated structure or a cast-in-situ structure, and the embedded steel sleeve 3 is embedded along with the construction of the intermediate wall 1.
The duct piece 2 is a reinforced concrete prefabricated component, and the anchor rod 4 is pre-buried along with the prefabrication process of the duct piece 2.
Although the foregoing embodiments have been described in some detail with reference to the accompanying drawings, it will be appreciated by those skilled in the art that various modifications and changes may be made thereto without departing from the scope of the utility model as defined in the appended claims, and thus are not repeated herein.
