Description

Technical Field

[0001] The utility model relates to the technical field of escape pipes, in particular to a combined installation steel base for escape pipes. Background Art

[0002] In the construction of highway tunnels, the escape pipe plays an irreplaceable role. It is installed in the tunnel by installing a steel base. In case of tunnel collapse, water seepage and other accidents, it is the "life channel" for construction workers and the "rescue channel" for external rescue workers. Therefore, there are high requirements for the strength, rigidity and stability of the escape pipe. At the same time, during installation, traditional escape pipes are usually cast iron steel pipes and glass fiber reinforced plastic pipes. The disadvantages of cast iron steel pipes are heavy weight, difficult connection, easy rust and short life. The disadvantages of glass fiber reinforced plastic pipes are high brittleness and poor impact resistance, especially steel pipes and glass fiber reinforced plastic pipes. Moreover, when a collapse occurs during highway tunnel construction, steel and glass pipes have poor pressure bearing capacity and environmental damage resistance.

[0003] During the installation process, the installation and fixing effect of the polyethylene escape pipe is poor, resulting in the overall loosening and rolling when impacted. At the same time, the polyethylene escape pipe is prone to severe deformation due to dismantling and transportation and loses its reuse value, which is not conducive to saving resources. Utility Model Content

[0004] To this end, the utility model provides a combined installation steel base for an escape duct to solve the above-mentioned problems in the prior art.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] According to a first aspect of the utility model, a combined steel mounting base for an escape pipe comprises:

[0007] A steel pipe rack is welded and fixedly installed on the outer side of the upper end of the I-beam, and a connecting steel is welded and fixedly installed on the inner side of the lower end of the I-beam, a polyethylene escape pipe is placed on the inner side of the steel pipe rack, and a transition elbow is installed on the outer side of the rear end of the polyethylene escape pipe;

[0008] A lower hoop ring is arranged at the outer side of the lower end of the connection between the I-beam and the transition elbow, and the outer side of the upper end of the lower hoop ring is connected to the upper hoop ring which is also located at the connection between the I-beam and the transition elbow, and a fixing bolt is installed through the connection between the lower hoop ring and the upper hoop ring;

[0009] A limiting ring is installed on the outside of the front end of the I-beam and is located on the outside of the front end of the polyethylene escape pipe, and a positioning column is fixedly installed at an equal angle inside the rear end of the limiting ring.

[0010] Furthermore, a support block is fixedly mounted on the outer side of the upper end of the connecting steel by screws, and the lower clamp ring is connected to the support block by plugging.

[0011] Furthermore, the upper end of the support block contacts the outer side of the lower end of the polyethylene escape pipe.

[0012] Furthermore, the front and rear sides of the upper end of the I-beam are both fixed with lifting rings by screws, and a steel wire rope is installed in the middle of the outer side of the I-beam.

[0013] Furthermore, the lower end of the steel wire rope is penetrated and arranged inside the outer side of the I-beam.

[0014] Furthermore, the limiting ring and the positioning column are connected to the polyethylene escape pipe in a plug-in manner, and the connection between the limiting ring and the steel pipe rack is provided with mounting bolts.

[0015] Furthermore, a hole structure which is adapted to and corresponds to the positioning column is opened inside the front end of the I-beam.

[0016] The utility model has the following advantages:

[0017] 1. Through the polyethylene escape pipe, the polyethylene escape pipe can be fixedly installed in the steel pipe rack under the action of the steel wire rope.

[0018] 2. The limiting ring can assist in reinforcing and positioning the fixed polyethylene escape pipe. The limiting ring further improves the installation and fixing effect of the polyethylene escape pipe, avoiding the phenomenon of loosening and rolling when the whole is impacted;

[0019] 3. Through the lower clamp ring and the upper clamp ring, during installation, make the pipe joints of the two sets of polyethylene escape pipes located in the lower clamp ring, then install the upper clamp ring on the outer side of the upper end of the polyethylene escape pipe and align it with the lower clamp ring, and fix it with fixing bolts and nuts, so as to facilitate the splicing and fixing of the two sets of polyethylene escape pipes and improve the firmness of the installation.

The requirements are met. The front and rear sides of the upper end of the I-beam 1 are fixed with lifting rings 7 by screws, so that the polyethylene escape pipe 5 can be hoisted as a whole through the lifting rings 7. A steel wire rope 8 is installed in the middle of the outer side of the I-beam 1. The lower end of the steel wire rope 8 is penetrated and arranged inside the outer side of the I-beam 1, so that the polyethylene escape pipe 5 can be hoisted and placed in the steel pipe rack 2. The steel wire rope 8 is then installed on the outer side of the polyethylene escape pipe 5, and the lower end of the steel wire rope 8 is fixed by a nut 12, so that the polyethylene escape pipe 5 can be fixed on the I-beam 1 through the steel wire rope 8.

[0027] The lower hoop ring 9 is arranged on the outer side of the lower end of the connection between the I-beam 1 and the transition elbow 6, and the upper end of the lower hoop ring 9 is connected to the outer side of the upper hoop ring 10 which is also located at the connection between the I-beam 1 and the transition elbow 6, and the connection between the lower hoop ring 9 and the upper hoop ring 10 is penetrated by a fixing bolt 11. The lower hoop ring 9 and the upper hoop ring 10 have a good fixing effect on the pipe joint of the polyethylene escape pipe 5. When two groups of polyethylene escape pipes 5 need to be spliced ​​and installed, the lower end of the lower hoop ring 9 can be inserted into the support block 4 first, and then the polyethylene escape pipe 5 can be hoisted to the lower The inner end of the hoop ring 9 makes the pipe joints of the two groups of polyethylene escape pipes 5 both located in the lower hoop ring 9, and then the upper hoop ring 10 is installed on the outer side of the upper end of the polyethylene escape pipe 5 and aligned with the lower hoop ring 9, and the fixing bolt 11 is inserted into the connection between the lower hoop ring 9 and the upper hoop ring 10, and fixed by the nut 12, so as to facilitate the fixation of the two groups of polyethylene escape pipes 5. The outer side of the rear end of the polyethylene escape pipe 5 is installed with a transition elbow 6. Similarly, the polyethylene escape pipe 5 and the transition elbow 6 can be spliced ​​and fixed to improve the firmness of the installation;

[0028] The outer side of the upper end of the connecting steel 3 is fixed with a support block 4 by screws, and the lower hoop ring 9 is connected to the support block 4 by plugging. The upper end of the support block 4 is in contact with the outer side of the lower end of the polyethylene escape pipe 5, so that the support block 4 can position the lower hoop ring 9 to avoid the angle deviation of the polyethylene escape pipe 5 in the later stage.
