Description

Technical Field

[0001] This utility model relates to the field of decorative ceiling keel construction technology, and in particular to a multi-adjustable connection structure for curved keels. Background Technology

[0002] With the continuous development of architectural design, more and more interior design projects are pursuing unique visual effects, especially high-end projects and landmark buildings, which use carefully designed curved shapes to present a perfect combination of dynamism and modernity in the interior design.

[0003] For curved ceiling panels, a matching curved keel is required. However, to ensure the installation accuracy of the ceiling panels, the curved shape of the keel is difficult to process. Furthermore, traditional keel installation uses hangers for control, and these hangers typically cannot be adjusted at a single point after installation. This makes it difficult to adjust the keel position if there is a significant deviation in the hanger's installation position. In particular, keel posture adjustment is usually done through the connection point between the hanger and the back of the keel, limiting the adjustment dimensions and making the adjustment process extremely inconvenient, thus failing to meet current interior decoration requirements.

[0004] Therefore, there is an urgent need for an adjustment system for curved keel that avoids the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-adjustable connection structure for curved keel, which solves the technical problems of existing curved arc keel where the curved arc processing is difficult, the hanger cannot usually be adjusted in space at a single point after installation, the keel posture adjustment is carried out through the connection node between the hanger and the back of the keel, the adjustment dimensions are small, the adjustment construction is extremely inconvenient, and it cannot meet the existing interior decoration requirements.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multi-adjustable connection structure for curved keel includes a set of roof main beams, a hanger frame, curved keels, and a multi-adjustable keel assembly.

[0008] The main roof beams are arranged in columns at transverse intervals.

[0009] The hanger frame is installed horizontally at intervals along the main roof beam, corresponding to the main roof beam. It includes hangers, the top of which is fixedly connected to the main roof beam. The arc formed by connecting the bottom ends of each hanger matches the curvature of the curved keel at its location.

[0010] The curved keel is composed of keel segments with straight sections replacing curves. The two ends of each keel segment are positioned at the bottom of two adjacent hangers. The two ends of adjacent keel segments and the bottom of the hangers are connected in an adjustable manner through a multi-adjustment keel assembly.

[0011] The keel multi-adjustment assembly includes a top adjusting bracket, a center adjusting shaft, and a spacing adjusting plate.

[0012] The top of the top adjusting corner piece is adjustable relative to the bottom of the hanger rod by swinging around a horizontal axis within the cross section. The top of the center adjusting shaft is adjustable relative to the bottom of the top adjusting corner piece by rotating around a vertical axis within the cross section. The bottom of the center adjusting shaft is located between the two ends of two adjacent keel sections. The two ends of the bottom of the center adjusting shaft are adjustable relative to one end of the spacing adjusting plate by swinging up and down in the vertical plane. The other end of the spacing adjusting plate is inserted into the end of the keel section and is adjustable horizontally relative to the keel section in the vertical plane.

[0013] The hanger frame also includes bottom rods and diagonal braces. The hangers are spaced apart along the bottom arc surface of the main beam. The bottom rods are sequentially connected to the bottom of each adjacent hanger. The diagonal braces are diagonally fixed between adjacent hangers and above the bottom rods.

[0014] The boom is made of angle steel and consists of two boom legs.

[0015] The top adjusting bracket includes a vertical limb plate and a horizontal limb plate. The vertical limb plate is adjustablely connected to the hanger limb plate via vertical limb plate bolts. The vertical limb plate bolts include adjusting bracket swing bolts and adjusting bracket fixing bolts.

[0016] The boom plate has two vertical circular holes. The vertical plate has an arc-shaped elongated hole for adjusting the angle fitting and a circular hole for adjusting the angle fitting, respectively, through which the swing bolt and the fixing bolt of adjusting the angle fitting pass and are anchored.

[0017] Two stiffening strips are also obliquely fixedly connected between the vertical and horizontal limbs of the top adjusting corner piece.

[0018] A central adjusting shaft connection hole is provided in the center of the horizontal limb plate.

[0019] The center adjusting shaft includes a center shaft screw, a center shaft sleeve, and sleeve wing plates. The sleeve wing plates are symmetrically welded to both sides of the center shaft sleeve. The top end of the center shaft screw passes through the connecting hole of the center adjusting shaft and is anchored on both sides by nuts. The bottom end of the center shaft screw passes through the center shaft sleeve and is anchored at both ends by nuts.

[0020] Each sleeve flange has two bolt connection holes: a round hole for adjusting the shaft near the central sleeve and an arc-shaped elongated hole for adjusting the shaft away from the central sleeve.

[0021] Two spacing adjustment holes are opened at one end of the spacing adjustment plate corresponding to the round hole of the adjustment shaft and the arc-shaped elongated hole of the adjustment shaft, and the fixing bolt and the swing bolt of the adjustment shaft pass through and are anchored respectively.

The other end of the spacing adjustment plate has two parallel oblong holes corresponding to the keel connection holes, which are respectively passed through and anchored by the keel spacing adjustment bolts.

[0024] Compared with the prior art, this utility model has the following features and beneficial effects:

[0025] This invention uses BIM modeling to fit the curved keel, simplifies the keel segment composition by replacing the curve with a straight one, and designs a multi-adjustment component between the keel segment and the hanger to achieve multi-dimensional posture adjustment between the bottom of the hanger and the keel segment.

[0026] This invention transforms the traditional single control of the bottom end of the hanger and the back side of the shaped curved keel into multiple controls of the posture of the bottom end of the hanger and the keel segment. Even if there is a large error in the installation of the hanger, the keel segment can be finely installed and adjusted through the keel multi-adjustment component to meet the installation accuracy requirements.

[0027] This utility model has four adjustment methods: the top adjustment corner piece controls the rotation angle of the keel section within its cross-section around the horizontal axis; the center adjustment shaft piece controls the rotation angle of the keel section within its cross-section around the vertical axis; the vertical warping angle of the keel section within its cross-section; and the spacing adjustment plate controls the distance between adjacent keel sections. The four adjustments work together to keep the keel section within the allowable installation error of the preset installation point. Attached Figure Description

Detailed Implementation

[0048] See the examples. Figure 1-11 As shown, a multi-adjustable connection structure for curved keel includes a set of roof main beams 1, hanger frame 2, curved arc keel and keel multi-adjustable components 4.

[0049] The main roof beams are arranged in columns at horizontal intervals.

[0050] The hanger frame 2 is installed transversely along the main roof beam 1, corresponding to the main roof beam 1. It includes hangers 21, the top of which is fixedly connected to the main roof beam 1. The arc formed by the connecting lines of the bottom ends of each hanger 21 matches the curvature of the curved keel at its location. The hanger frame 2 also includes base rods 22 and diagonal braces 23. The hangers 21 are spaced apart along the bottom arc surface of the main roof beam 1. The base rods 22 sequentially connect to the bottom of each adjacent hanger 21. The diagonal braces 23 are diagonally fixed between adjacent hangers 21 and above the base rods 22. The hangers 21 are angle steel and include two hanger leg plates 211.

[0051] The curved keel is composed of keel segments 3 with straight sections instead of curves. The two ends of the keel segments 3 are respectively set at the bottom ends of two adjacent hangers 21. The two ends of the adjacent keel segments 3 and the bottom ends of the hangers 21 are connected in an adjustable manner through the keel multi-adjustment assembly 4.

[0052] The keel multi-adjustment assembly 4 includes a top adjustment corner piece 41, a center adjustment shaft piece 42, and a spacing adjustment plate 43.

[0053] The top of the top adjusting angle piece 41 is adjustable relative to the bottom of the hanger rod by swinging around a horizontal axis within the cross section. The top of the center adjusting shaft piece 42 is adjustable relative to the bottom of the top adjusting angle piece 41 by rotating around a vertical axis within the cross section. The bottom of the center adjusting shaft piece 42 is located between the two ends of two adjacent keel sections 3. The two ends of the bottom of the center adjusting shaft piece 42 are adjustable relative to one end of the spacing adjusting plate 43 by swinging up and down in the vertical plane. The other end of the spacing adjusting plate 43 is inserted into the end of the keel section 3 and is horizontally adjustable relative to the keel section 3 in the vertical plane.

[0054] The top adjusting bracket 41 includes a vertical limb plate 411 and a horizontal limb plate 412. The vertical limb plate 411 is adjustablely connected to the boom limb plate 211 via vertical limb plate bolts, which include adjusting bracket swing bolts 44 and adjusting bracket fixing bolts 45. The boom limb plate 211 has two vertically oriented circular holes. Corresponding to the two circular holes, the vertical limb plate 411 has an arc-shaped elongated hole 413 and an adjusting bracket circular hole 414, which respectively pass through and are anchored to the adjusting bracket swing bolt 44 and adjusting bracket fixing bolt 45. Two stiffening strips 416 are also obliquely fixedly connected between the vertical limb plate 411 and the horizontal limb plate 412 of the top adjusting bracket 41.

[0055] A central adjusting shaft connection hole 415 is provided in the center of the horizontal limb plate 412. The central adjusting shaft 42 includes a central shaft screw 421, a central shaft sleeve 422, and sleeve wing plates 423. The sleeve wing plates 423 are symmetrically welded to both sides of the central shaft sleeve 422. The top end of the central shaft screw 421 passes through the central adjusting shaft connection hole 415 and is anchored on both sides by nuts 49. The bottom end of the central shaft screw 421 passes through the central shaft sleeve 422 and is anchored at both ends by nuts 49. Each sleeve wing plate 423 has two bolt connection holes: a circular adjusting shaft hole 424 near the central shaft sleeve and an arc-shaped elongated adjusting shaft hole 425 away from the central shaft sleeve.

[0056] One end of the spacing adjustment plate 43 has two spacing adjustment plate holes 431 corresponding to the round hole 424 and the arc-shaped elongated hole 425 of the adjusting shaft, respectively, which are then passed through and anchored by the adjusting shaft fixing bolt 46 and the adjusting shaft swing bolt 47. The keel section 3 is a C-shaped steel, which includes a keel back plate 31 and a keel side plate 32. The keel back plate 31 has two keel connecting round holes, one upper and one lower. The other end of the spacing adjustment plate 43 is tightly attached to the keel back plate 31 at the end of the keel section. The other end of the spacing adjustment plate 43 has two parallel elongated holes 432 corresponding to the keel connecting round holes, which are then passed through and anchored by the keel spacing adjustment bolt 48.

[0057] The construction method for this type of curved keel with multiple adjustable connection structure is as follows:

[0058] Step 1, Keel Structure Detailing Design: Establish an overall curved keel BIM model, and set up keel segments 3 along the longitudinal direction of the plate by folding instead of bending. Determine the processing length of each keel segment 3 in the model.

[0059] Step 2, Detailed design of installation points: Scan the completed roof main beams, collect information and create a BIM model to form a point model. Collaborate with the BIM model of the curved keel in Step 1. In the point model, pre-simulate the installation points of each hanger frame 2, keel segment 3 and keel multi-adjustment component 4 to determine the quantity, size and installation point of each component.

[0060] Step 3, Construction of the hanger frame: Install the hanger frame 2 according to the installation points determined in Step 2. The bottom of the hanger 21 is pre-installed with the keel multi-adjustment component 4. The hanger frame 2 is lifted as a whole. The top of the hanger 21 is fixedly connected to the roof main beam 1. After installation, the bottom of the hanger 21 is scanned, information is collected and BIM modeling is performed. The model is compared with the preset point model in Step 2 and then adjusted to ensure that the arc formed by the connection of the bottom ends of each hanger 21 fits the curvature of the curved keel.

[0061] Step 4, install the keel section: install the keel section 3 according to the installation points determined in Step 2, that is, lift the keel section 3 and then connect the ends to the corresponding keel multi-adjustment components 4.

[0062] Step 5: Adjust the keel multi-adjustment components:

[0063] The adjusting angle bracket swing bolt 44 adjusts the swing angle of the top adjusting angle bracket 41 within the arc-shaped elongated hole 413 of the adjusting angle bracket, thereby driving the central adjusting shaft 42 to adjust the rotation angle of the keel section 3 around the horizontal axis within its cross section.

[0064] The relative anchoring position of the central shaft sleeve 422 and the central shaft screw 421 determines the rotation position of the sleeve wing plate 423, which in turn drives the central adjusting shaft 42 to adjust the rotation angle of the keel section 3 about the vertical axis within its cross section.

[0065] The adjusting shaft swing bolt 47 adjusts the up-and-down warping angle within the cross-section of the keel section 3 within the arc-shaped elongated hole 425 of the adjusting shaft.

[0066] The keel spacing adjusting bolt 48 adjusts the distance between adjacent keel segments 3 within the oblong hole 432 of the insert plate.

[0067] Four adjustments are made to ensure that the keel section 3 and the installation point determined in step two are kept within the allowable installation error.

[0068] The multiple adjustment mechanisms of this invention are as follows:

[0069] The adjusting angle piece swing bolt 44 adjusts the swing angle of the top adjusting angle piece 41 within the arc-shaped elongated hole 413 of the adjusting angle piece, thereby driving the central adjusting shaft piece 42 to adjust the adjustable rotation angle of the cross section of the keel section 3 around the horizontal axis.

[0070] The relative anchoring position of the central shaft sleeve 422 and the central shaft screw 421 determines the rotation position of the sleeve wing plate 423, which in turn drives the central adjusting shaft 42 to adjust the adjustable rotation angle of the cross section of the keel section 3 around the vertical axis.

[0071] The adjusting shaft swing bolt 47 swings up and down in the vertical plane within the arc-shaped elongated hole 425 of the adjusting shaft to adjust the up and down warping angle within the cross section of the keel section 3.

[0072] The keel spacing adjustment bolt 48 adjusts the distance between adjacent keel segments 3 within the oblong hole 432 of the insert plate.
