Description

A building facade keel misalignment fixing device Technical Field

[0001] This utility model relates to the field of building construction, specifically a device for fixing misaligned holes in the keel of a building facade. Background Technology

[0002] The exterior facade refers to a lightweight wall structure installed on the outside of a building wall using a keel system. It does not bear any load and serves only a decorative purpose. The keel needs to be installed at fixed horizontal and vertical spacings to form installation grids consistent with the decorative panels. The keel is generally fixed to the wall using expansion bolts or pre-embedded bolts. However, it is impossible to precisely control the position of the pre-embedded bolts to perfectly match the hole positions on the keel during the initial construction phase. On the contrary, misalignment is the norm. Expansion bolts are also used for fixing, but in places where expansion bolts cannot be installed, such as when reinforcing bars are embedded in the wall, misalignment is still necessary. To accommodate this misalignment, long holes are usually made along the length of the keel. However, this can only accommodate misalignment within the length of the long hole and along the length of the keel. Moreover, if the length of the long hole is too large, it will affect the strength of the keel.

[0003] The invention patent with application number CN202011066553.9 provides a quick installation structure for wall decorative panels. It achieves the purpose of adjusting the position within the entire length of the keel by setting grooves throughout the keel and sliding bolts in the grooves. However, it can only be adjusted in the length direction of the keel, and cannot install for misalignments on the outside of the keel. Moreover, this patent requires a specially made keel and is not universal. Summary of the Invention

[0004] This utility model provides a fixing device for misaligned holes in the keel of a building facade, which aims to solve the problem of poor adjustability when the keel is installed in a misaligned manner.

[0005] The technical solution includes two sets of sliding arm units. Each set of sliding arm units includes a slider and a connecting arm. The slider is slidably mounted on the keel. One end of the connecting arm is hinged to the slider, and the other end of the connecting arm has a first hinge hole. During installation, the first hinge hole at the outer end of the connecting arm of the two sets of sliding arm units passes through the same pre-embedded bolt or expansion bolt. It also includes a clamping nut, which is screwed onto the outer end of the pre-embedded bolt or expansion bolt to clamp the ends of the two connecting arms.

[0006] The slider is U-shaped, and a hinge bolt is screwed onto the opening of the slider. A second hinge hole is opened at the connection end between the connecting arm and the slider. The second hinge hole is fitted onto the hinge bolt to realize the hinge connection between the connecting arm and the slider.

[0007] Both ends of the first hinge hole are provided with circumferentially distributed meshing teeth, and the lower side of the clamping nut is also provided with circumferentially distributed meshing teeth.

[0008] The slider is equipped with a locking nut, which can lock the slider onto the keel and restrict the slider's movement.

[0009] This utility model enables connection to the external bolt position of the keel through the extension of two connecting arms. By changing the included angle of the two connecting arms, it can adapt to the vertical distance between the bolt and the keel. By sliding the slider on the keel, it can adapt to the longitudinal position of the bolt on the keel, thus enabling connection to any bolt position. After the connection is completed, tightening the clamping nut can fix the included angle of the connecting arms, achieving a rigid connection between the bolt and the keel and completely fixing the keel.

[0010] Moreover, this utility model does not require opening long grooves on the keel, does not affect the strength of the keel, does not require on-site drilling, is easy to install, and can be adapted to existing keels, thus having good versatility. Attached Figure Description

[0016] Referring to the accompanying drawings, this utility model includes two sets of sliding arm units. Each set of sliding arm units includes a slider 1 and a connecting arm 2. The slider 1 is slidably mounted on the keel. One end of the connecting arm 2 is hinged to the slider 1, and the other end of the connecting arm 2 has a first hinge hole 3. During installation, the first hinge hole 3 at the outer end of the connecting arm 2 of the two sets of sliding arm units passes through the same pre-embedded bolt or expansion bolt. It also includes a clamping nut 4, which is screwed onto the outer end of the pre-embedded bolt or expansion bolt to press the ends of the two connecting arms 2 tightly. After installation, the two sets of sliding arm units and the keel form an isosceles triangle structure. The two sliders 1 are located at one vertex, the pre-embedded bolt or expansion bolt is located at another vertex, and the positions of the first hinge holes 3 of the two connecting arms 2 are pressed by the clamping nut, so that the angle between the two connecting arms 2 is fixed and the length of the two connecting arms 2 is also fixed. Therefore, the triangle is uniquely determined, that is, a rigid connection is formed between the keel and the pre-embedded bolt or expansion bolt, thereby achieving the fixation of the keel.

[0017] The slider 1 is U-shaped, and a hinge bolt 5 is screwed onto the opening of the slider 1. The connecting end of the connecting arm 2 and the slider 1 has a second hinge hole 6. The second hinge hole 6 is fitted onto the hinge bolt 5 to realize the hinge connection between the connecting arm 2 and the slider 1. The U-shaped slider 1 can be easily locked onto the keel, and then the hinge bolt 5 is screwed on to connect it to the connecting arm 2.

[0018] Both ends of the first hinge hole 3 are provided with circumferentially distributed meshing teeth 7, and the lower side of the clamping nut 4 is also provided with circumferentially distributed meshing teeth 7. After the outer ends of the two connecting arms 2 are clamped by the clamping nut 4, the meshing teeth 7 on the two connecting arms 2 and the meshing teeth 7 on the clamping nut 4 mesh with each other, so that the two connecting arms 2 cannot rotate around the pre-embedded bolt or expansion bolt, thereby fixing the position of the angle of the two connecting arms 2.

[0019] The slider 1 is equipped with a locking nut 8, which can lock the slider 1 onto the keel, restrict the sliding of the slider 1, and further improve the stability of the connection.

[0020] When using this utility model, if the pre-embedded bolts or expansion bolts on the wall are located outside the keel, the two U-shaped sliders 1 of the keel are clamped onto the keel, with the open side of the sliders 1 facing the pre-embedded bolts or expansion bolts. Then, the second hinge holes 6 of the two connecting arms 2 are placed in the openings of the sliders 1 and hinge bolts 5 are installed to achieve the hinge connection between the two connecting arms 2 and the sliders 1. Then, the first hinge holes 3 of the two connecting arms 2 are fitted onto the pre-embedded bolts or expansion bolts and the clamping nuts 4 are tightened. When the clamping nuts 4 are not fully tightened, the two connecting arms 2 can rotate around the pre-embedded bolts or expansion bolts. At this time, the position of the keel can be adjusted. After the keel is adjusted to the designed position, the clamping nuts 4 are tightened so that the two connecting arms 2 and the meshing teeth 7 on the clamping nuts 4 mesh with each other. Then the included angle and position of the connecting arms 2 are fixed. At this time, a rigid connection is formed between the keel and the pre-embedded bolts or expansion bolts, and the keel is completely fixed.

[0021] This invention can achieve connection with any bolt position without the need to open long grooves on the keel, without affecting the strength of the keel, without the need for on-site drilling, is easy to install, can be adapted to existing keels, and has good versatility.
