Description

Technical Field

[0001] The invention belongs to the technical field of backfilling of steel perimeter purlins, and in particular relates to a method and a device for backfilling mortar between a gap between a steel perimeter purlin and a protective structure. Background Art

[0002] In station construction, the retaining structure is mostly made of retaining piles or ground-connected walls. During the trenching and hole-making process, due to the different soil media, the excavation surface of the retaining structure is easily uneven and has bumps and bumps. The support is made of steel purlins and steel supports. There are the following problems when filling the steel purlins and retaining structure mortar: (1) Geotextiles or small wooden boards are often used for back filling of steel purlins, which are easy to deform during filling, resulting in incomplete filling; (2) The bottom formwork is mostly sealed with woven bags. After filling, they dare not be inserted to make it dense. The bottom formwork is difficult to fix and is easy to expand, resulting in repeated construction. At the same time, the filling may not be sufficient, resulting in uneven force on the steel purlin. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a method and device for backfilling mortar between the gap between steel purlin and enclosure structure, which is suitable for different enclosure structure base surfaces and can better ensure the fullness and density of the backfill mortar behind the steel purlin.

[0004] The specific content of the present invention is a method for backfilling mortar between the gap between the steel purlin and the enclosure structure, the steps of which include:

[0005] (1) Weld a spring bottom plate on the side form where the steel purlin contacts the enclosure structure. The length of the spring bottom plate is the same as the length of the steel purlin.

[0006] (2) Weld the spring onto the spring bottom plate;

[0007] (3) Weld the spring top cap plate on the top surface of the spring;

[0008] (4) Holes are opened on the diagonal sides of the spring top cap plate, and a limit steel rod is passed through the hole. The bottom end of the limit steel rod is welded to the bottom plate of the spring to ensure that the working direction of the spring is perpendicular to the bottom plate;

[0009] (5) Weld the bottom mold steel plate onto the spring top cap plate.

[0010] According to the solution, the working principle of the bottom formwork steel plate is similar to that of a switchblade. The bottom formwork steel plate pops out under the action of a spring and forms a connection with the retaining structure, serving as a bottom formwork for backfilling mortar behind the steel purlin. The bottom formwork steel plate serves as the bottom plate for backfilling mortar behind the steel purlin, meets the filling quality, and ensures that the supporting force is evenly transferred to the retaining structure.

[0011] A mortar backfilling device for the gap between a steel purlin and a retaining structure comprises a spring bottom plate welded to a side form where the steel purlin contacts the retaining structure, a plurality of springs welded at equal intervals to the upper portion of the spring bottom plate, a spring top cap plate welded to the top surface of the springs, and a bottom formwork steel plate welded to the spring top cap plate, wherein two openings are provided at two opposite diagonals of the spring top cap plate, a limiting steel rod is installed on the opening, and the limiting steel rod passes through the opening and is fixed to the spring bottom plate.

[0012] According to a further solution, the length of the spring bottom plate is consistent with the length of the steel purlin.

[0013] According to a further solution, the spring is welded at a center position of the spring top cap plate.

[0014] According to a further solution, the springs are welded at equal intervals on the center line of the spring bottom plate.

[0015] According to a further solution, the bottom mold steel plate is a rectangular structure and is horizontally arranged at the center of the spring top cap plate.

[0016] The advantages of the present invention are: the working principle of the bottom template of the present invention is similar to that of a switchblade. The bottom template steel plate pops out under the action of the spring and forms a connection with the enclosure structure, serving as the bottom template for backfilling mortar behind the steel purlin. The bottom template steel plate is used as the bottom plate for backfilling mortar behind the purlin, which meets the filling quality and ensures that the supporting force is evenly transmitted to the enclosure structure, greatly improving the applicability of the uneven enclosure structure, playing a solid supporting protection role in station construction, and ensuring safe operation during construction.
