Description

Technical Field

[0001] The invention relates to a ceiling keel assembly, in particular to a combined integrated ceiling keel. Background Art

[0002] In interior decoration, ceiling is a common decoration option. Ceiling is divided into two types according to the material: gypsum board ceiling and gusset ceiling. The gusset ceiling is made of multiple gussets. The gusset ceiling requires corresponding ceiling keel components to construct the skeleton for installing the gusset. The ceiling keel components generally include expansion screws, screws, first connecting parts, main keels, second connecting parts and triangular keels. The expansion screws are hit on the ceiling, and the weight of the entire ceiling is borne by the expansion screws. The screws are screwed vertically downward on the expansion screws. The first connecting part is fixed to the lower end of the screw, and the main keel is fixed to the first connecting part. The second connecting part is used to connect and fix the main keel and the triangular keel. The triangular keel is located below the main keel. The two are perpendicular to each other, and the gusset is buckled between the two triangular keels.

[0003] During the installation process, in order to ensure the flatness of the ceiling, the height of the first connector on each screw needs to be adjusted to ensure that the main keels are all at the same height level, so that the triangular keels can be kept at the same height level. However, in actual installation, it is difficult to control the vertical installation angle of the expansion screw, because it is impossible to accurately control the drilling angle when manually drilling holes on the ceiling, and there will also be a certain deviation in the position of the holes, which will result in the screw being unable to remain vertical. Even if the master can manually bend and twist the screw to make it as vertical as possible, and adjust the installation height of the first connector on the screw so that the height of all the first connectors tends to be consistent, the projection of the first connector on the ceiling cannot be guaranteed to be within the marked range. This will cause the main keel to be installed because the first connectors are not distributed in a straight line, resulting in the main keel being unable to remain straight. Summary of the invention

[0004] The present invention provides a combined integrated ceiling keel, which solves the problem in the prior art that the overall horizontal adjustment is difficult because the installation angle of the screw cannot be guaranteed to be vertical.

[0005] The above technical problems of the present invention are mainly solved by the following technical solutions: a combined integrated ceiling keel, comprising a plurality of expansion screws, a plurality of screw rods, a plurality of first connecting members, a plurality of main keels, a plurality of second connecting members and a plurality of triangular keels, the expansion screw comprising a sleeve and a core column arranged inside the sleeve, a screw hole is formed on the core column, the upper end of the screw rod can be extended into the sleeve and screwed with the core column, an upper limit nut and a lower limit nut are screwed on the screw rod, the upper limit nut can be screwed to abut against the sleeve, the heights of all lower limit nuts are set at the same height, a rotating seat is provided on the screw rod and on the upper side of the lower limit nut, an extension arm extends outward from the rotating seat, the first connecting member is suspended on the extension arm, the main keel is suspended on a plurality of the first connecting members, the distribution directions of all main keels are consistent and at the same height, the triangular keel is fixed to the bottom of the main keel through the second connecting member, and is perpendicular to the distribution axis of the main keel.

[0006] The components provided by the present invention can be assembled in the following manner: the first step is to mark the points on the ceiling and then drill holes; the second step is to screw the screw rods and the screw holes on the core column, then insert the docked expansion screws into the holes, and tighten the core column in the expansion screw by tightening the upper limit nut. The downward movement of the core column will push the expansion petals on the sleeve to expand outward, thereby achieving a tight fixation of the expansion screw and the hole; the third step is to manually straighten the severely deflected screw rods, and use a laser level to assist in adjusting the height of the lower limit nuts on all screw rods to make the height uniform; the fourth step is to set the rotating seat sleeve on all the lower limit nuts, and then hang the first connecting piece on the extension arm of the rotating seat; the fifth step is to build the main keel on several first connecting pieces, and keep the main keel straight by adjusting the direction of the extension arm on the rotating seat; the sixth step is to fix the triangular keel through the second connecting piece.

[0007] The rotating seat in the present invention can change the direction of the extension arm by rotating, and the first connecting member is suspended on the extension arm of the rotating seat, so the first connecting member can move freely within the circular range of the extension arm as the radius to adjust its position to ensure that the main keel remains straight. The first connecting member and the rotating seat in the present invention can only provide pulling force and cannot locate the horizontal position of the main keel. Only when the main keel and the triangular keel are completely fixed, the keel network is completed, and the keel network is abutted against the wall on all sides, the keel network can be completely fixed.

[0008] The triangular keel, the second connecting member and the main keel in the present invention are basically the same as those of existing products, and the installation method can also refer to the installation of existing keels.

[0009] Therefore, compared with the prior art, the present invention has the following characteristics: 1. The present invention adjusts the height of the lower limit nut by rotating to achieve a uniform installation height of the main keel; 2. The first connecting piece can move freely within a circular range with the extension arm as the radius to adjust its own position to ensure that the main keel remains straight, so that after all the keels are networked, the overall structure is flatter.

[0017] Example 1: See Figure 1 and Figure 2A combined integrated ceiling keel comprises a plurality of expansion screws 10, a plurality of screw rods 20, a plurality of first connecting members 30, a plurality of main keels 40, a plurality of second connecting members 50 and a plurality of triangular keels 60. The expansion screw comprises a sleeve 11 and a core column 12 arranged inside the sleeve. A screw hole is formed on the core column. The upper end of the screw rod can be inserted into the sleeve and screwed with the core column. An upper limit nut 70 and a lower limit nut 80 are screwed on the screw rod. The upper limit nut can be screwed until it abuts against the sleeve. The heights of all lower limit nuts are set at the same height. A rotating seat 90 is provided on the screw rod and is movably sleeved on the upper side of the lower limit nut. An extension arm 91 extends outward from the rotating seat. The first connecting member is suspended on the extension arm, and the main keels are suspended on the plurality of first connecting members. The distribution directions of all main keels are consistent and at the same height. The triangular keel is fixed to the bottom of the main keel through the second connecting member and is perpendicular to the distribution axis of the main keel.

[0018] The components provided in this embodiment can be assembled in the following ways: the first step is to mark the points on the ceiling and then drill holes; the second step is to screw the screw rod and the screw hole on the core column, and then insert the docked expansion screw into the hole, and tighten the core column in the expansion screw by tightening the upper limit nut. The downward movement of the core column will push the expansion petal on the sleeve to expand outward, thereby achieving a tight fixation of the expansion screw and the hole; the third step is to manually straighten the severely deflected screw rod, and use a laser level to assist in adjusting the height of the lower limit nuts on all screw rods to make the height uniform; the fourth step is to set the rotating seat sleeve on all the lower limit nuts, and then hang the first connecting piece on the extension arm of the rotating seat; the fifth step is to build the main keel on several first connecting pieces, and keep the main keel straight by adjusting the direction of the extension arm on the rotating seat; the sixth step is to fix the triangular keel through the second connecting piece. The triangular keel, the second connecting piece and the main keel in this embodiment are basically the same as the existing products, and the installation method can also refer to the installation of the existing keel.

[0019] Specifically, the first connecting member in this embodiment includes a hook 31, a connecting body 32, a bearing body 33 and a limiting body 34. A slot 35 with an upward opening is defined between the connecting body, the bearing body and the limiting body. The main keel can be directly inserted into the slot from the upper side and kept fixed; the hanging point of the hook and the extension arm is located on the center plane of the slot. Figure 3 The first connecting piece is formed by bending a steel wire.

[0020] See Figure 1 and Figure 4 The rotating seat in this embodiment is composed of a vertical sleeve 92 and a horizontal chassis 93, the sleeve is sleeved on the screw, the chassis is fitted with the upper surface of the lower limit nut, and the outer end of the extension arm is provided with an upwardly protruding anti-drop rod 94. The rotating seat is made of stainless steel or galvanized iron.

[0021] See Figure 1, specifically, the upper limit nuts and the upper sides of the lower limit nuts in this embodiment are respectively provided with a first round-edge body 71 and a second round-edge body 81 extending outward. The cross-sectional area of the round-edge body is larger than that of the limit nut, so a larger contact area can be increased. The first round-edge body can reduce the pressure between the wall surface and increase the contact friction, and the second round-edge body can provide a larger supporting area.

[0022] Specifically, the main keel in this embodiment is a U-shaped sheet metal part. Two main keels can be butted head to tail by referring to the attached Figure 5 way, and the butting part can be directly lapped in the slot of the first connecting piece.

[0023] It will be obvious to those skilled in the art that the present invention can be changed into various ways, and such changes are not considered to depart from the scope of the present invention. All such modifications obvious to those skilled in the art will be included within the scope of the present claims.
