Description

Technical Field

[0001] This utility model relates to the technical field of wall keel leveling structure, and in particular to a wall keel and a wall keel leveling structure. Background Technology

[0002] With the emergence of prefabricated buildings, prefabricated interior structures have followed suit and been developed and applied. Due to their short installation time, quick completion, and mostly dry construction methods, they have received widespread attention in the construction industry.

[0003] Existing overhead support structures have the following disadvantages:

[0004] 1. Most existing wall-mounted support structures only serve to level the civil engineering wall surface. They cannot meet the weight requirements of decorative wall panels and hanging cabinets, etc. The weight of decorative wall panels and other items still needs to be placed on the ground.

[0005] 2. When most existing kitchen wall cabinets and other items that need to be hung on the wall are installed on walls with wall-mounted support structures, it is necessary to add a filling board to the open space to ensure sufficient support for the hanging weight.

[0006] 3. Most existing overhead keel structures are "bow" shaped with an open design at one end. They are weak in rigidity and have low resistance to deformation, making them unable to support items that need to be hung on the wall directly on the keel.

[0007] 4. Most existing wall leveling bracket structures are connected to the civil engineering wall by simply screwing in the adjusting screw into the plastic expansion tube, which expands and then grips the civil engineering wall. This brings the risk that the adjusting screw may fall off if it is screwed in too shallowly.

[0008] 5. Most existing single-set wall leveling support structures are connected to the civil engineering wall, which requires drilling multiple holes in the wall, making construction cumbersome and posing a risk of weakening the strength of the civil engineering wall.

[0009] 6. Most existing overhead keel installations have the open end facing the building wall, which means that when heavy objects are hung on the keel, there is no supporting structure on the inside. Utility Model Content

[0028] Specifically, the inner-outer thread conversion sleeve 2 can be formed by a cold-rolled steel integrated mold or by a combination of separate components (an outer thread screw and a gasket nut with a gasket).

[0029] The outer thread of the inner-outer thread conversion sleeve 2 is self-tapping: used in cooperation with the expansion pipe 1 to expand the expansion pipe 1 in place in the civil wall 9, avoiding falling off; the inner thread is a standard metric thread, threaded with the adjusting screw 4, and the installation cooperation is convenient.

[0030] The gasket nut in the inner-outer thread conversion sleeve 2 can be in the form of a hexagonal head, facilitating the use of an outer hexagonal wrench for locking and installation.

[0031] The gasket of the gasket nut can be in the form of a large-diameter disc, and after installation, the gasket of the gasket nut is attached to the civil wall surface, increasing the stress area of the wall surface and making the entire bracket stronger.
