Description

Technical Field

[0001] This utility model belongs to the field of construction, specifically relating to a profiled steel sheet wall foot connection structure, which can effectively improve the sealing performance between the profiled steel sheet and the wall at the wall foot. Background Technology

[0002] Most large factories or warehouses nowadays are built using steel structures. After the main structure is completed, a wall is built around the lower part of the steel structure building, and profiled steel sheets are installed on the wall to form the building walls.

[0003] The conventional construction method for building walls is as follows: the lower part is a 240mm thick brick wall, with profiled steel sheets installed on top to form the wall structure. However, due to the excessively large column spans and increased beam widths in some factories or warehouses, gaps can easily form between the upper profiled steel sheet and the lower wall, sometimes even causing the steel sheet to hang precariously on the outside of the brick wall. Dust from inside the building can easily leak out through these gaps. One solution is to replace the 240mm thick brick wall with a 370mm thick brick wall, but this increases the construction cost.

[0004] To address the aforementioned issues, this invention provides a profiled steel sheet wall foot connection structure by installing a capping at the top of a 240mm thick brick wall and projecting it out of the wall surface. The projecting length is adjusted according to the width of the wall beam. This structure offers excellent waterproofing, sealing, and durability, and is also simple to construct and easy to maintain. Summary of the Invention

[0005] This utility model provides a profiled steel sheet wall foot connection structure, including a wall, a cantilevered top, C-shaped steel purlins, a support plate, flashing, profiled steel sheet, foam plugs, self-tapping screws, and sealant.

[0006] The perimeter wall is built on the outside of the steel columns of the factory building, and a coping cantilever is set at the top of the perimeter wall; C-shaped steel purlins are attached to the outside of the steel columns and fastened to the coping cantilever, and the C-shaped steel purlins and the steel columns are connected by a support plate.

[0007] The base plate of the pallet is a perforated square steel plate, and a square steel plate of the same length as the base plate is vertically installed on the center line of the base plate; the base plate of the pallet is placed on a C-shaped steel purlin, and the pallet is fixedly connected to the C-shaped steel purlin with anchor bolts; the T-shaped side of the pallet is closely attached to the steel column and welded to the steel column.

[0008] The vertical edge of the flashing is close to the outer edge of the C-shaped steel purlin, and the inclined plate of the flashing rests on the edge of the coping protrusion.

[0009] The profiled steel sheet is placed on the inclined plate of the flashing, close to the vertical edge of the flashing; the connection between the profiled steel sheet and the vertical edge of the flashing is sealed with foam plugs to close the gap at the connection between the profiled steel sheet and the vertical edge of the flashing.

[0010] The profiled steel sheet and flashing are fixed to the C-shaped steel purlins with self-tapping screws. The gap between the bottom of the profiled steel sheet and the inclined plate of the flashing is sealed with sealant to enhance the airtightness of the wall base connection structure from the inside out.

[0011] The beneficial effects of this utility model are as follows: This utility model features a cantilevered coping at the top of the wall, upon which C-shaped steel purlins and flashing are installed. A support plate is used to fix the C-shaped steel purlins to the steel columns, and the profiled steel sheet is placed on the flashing. Self-tapping screws are used to fix the profiled steel sheet and flashing to the C-shaped steel purlins, ensuring the strength and stability of the profiled steel sheet wall base. The cantilevered coping prevents rainwater from entering the factory building, and the joints are sealed with sealant and foam plugs, improving the overall airtightness of the steel structure factory building and reducing problems such as suspended profiled steel sheets, thereby further enhancing the overall facade effect of the factory building and ensuring durability. This technical solution has excellent waterproofing, sealing, and durability, and also has the advantages of simple construction and easy maintenance. Attached Figure Description
