Description

Technical Field

[0001] This utility model relates to the field of construction technology for building walls and ceilings, and in particular to a U-shaped perforated load-bearing edge keel. Background Technology

[0002] In the field of building wall and ceiling construction, the edge keel is a key load-bearing component connecting the cladding keel to the wall. Its structural design and installation method directly affect the construction efficiency and project quality. At present, the common construction methods mainly use wooden frame or metal edge keel as the support structure. The wooden frame needs to fix the wooden keel to the wall first, and then install the cladding keel to form a stable hoisting frame. The metal edge keel is directly connected to the cladding keel with self-tapping screws to improve fire resistance and structural strength.

[0003] However, existing wooden keel ceiling construction methods suffer from low efficiency, weak structural strength, lack of adjustability, fire resistance, waterproofing, corrosion resistance, and environmental friendliness. Ordinary light steel keel installation is cumbersome, lacks fine-tuning capabilities, and is labor-intensive and material-intensive. Therefore, those skilled in the art have provided a U-shaped perforated load-bearing edge keel to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a U-shaped perforated load-bearing keel. The keel frame is attached to the wall and fixed using expansion bolts passing through two wall positioning holes. These wall fixing holes allow for ±3mm fine-tuning. Subsequently, multiple covering keels are placed inside the rear wall of the keel frame and rivets are passed through the first and second connecting holes. This installation and positioning between the keel frame and the covering keels allows for ±10mm fine-tuning, thus resolving the cumulative error during the hoisting and installation of the covering keels.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a U-shaped perforated load-bearing keel, comprising a keel frame, wherein wall positioning holes are respectively provided at the center of the front sidewall of the keel frame near both sides, the two wall positioning holes respectively penetrate the front sidewall of the keel frame and lead to the rear side, wherein a plurality of first connecting holes are provided at the center of the upper end face of the keel frame near the rear edge, the lower ends of the plurality of first connecting holes respectively penetrate the upper end face of the keel frame and lead to the lower end, wherein a plurality of covering keels are provided inside the rear sidewall of the keel frame, and a plurality of second connecting holes are respectively provided through the upper end faces of the plurality of covering keels on both sides;

[0006] With the above technical solution, during use, the front sidewall of the keel frame is attached to the wall and fixed by using expansion bolts through two positioning holes in the wall. The wall fixing holes can be adjusted by ±3mm. Then, multiple covering keels are placed inside the rear sidewall of the keel frame and rivets are used through the first and second connecting holes. By installing and positioning the keel frame and the covering keels, ±10mm fine adjustment can be provided, solving the problem of accumulated errors in the hoisting construction of the covering keels.

[0007] Furthermore, the height of the plurality of the covering keels is adapted to the height between the upper and lower inner sidewalls of the keel frame;

[0008] The above technical solution facilitates assembly during the assembly process.

[0009] Furthermore, the length of the first connecting hole is the same as the width of the two second connecting holes;

[0010] The above technical solution facilitates installation while allowing for fine-tuning within a limited range, providing ±10mm fine-tuning.

[0011] Furthermore, the width of the upper end face of the keel frame is wider than the width of the lower end face;

[0012] The above technical solution allows for easy installation and connection of the covering keel due to its wider upper surface, while the narrower lower surface provides partial support for the lower end of the covering keel.

[0013] Furthermore, the keel frame is made of galvanized steel sheet;

[0014] The above technical solution has excellent corrosion resistance, waterproof and fireproof properties, and a long overall service life.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the keel frame is designed as an integral piece. The front sidewall of the keel frame is attached to the wall and fixed by expansion screws through two positioning holes in the wall. The wall fixing holes can be adjusted by ±3mm. Then, multiple covering keels are placed inside the rear sidewall of the keel frame and rivets are used to install and position the keel frame and the covering keels. This allows for ±10mm fine adjustment and solves the problem of accumulated errors in the hoisting construction of the covering keels.

[0017] 2. In this utility model, by setting the material of the keel frame to galvanized steel plate, it has excellent corrosion resistance, waterproof and fireproof effects, and a long service life. Attached Figure Description
