Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a connecting structure between a ceiling suspender and a conversion layer. Background Art

[0002] At present, in the decoration project, the ceiling suspenders are still installed on the ceiling conversion layer by the traditional method of drilling holes in the angle steel. In actual construction, it often occurs that the suspenders cannot correspond to the installation holes on the angle steel, resulting in the inclined installation of the ceiling suspenders or the spacing of the ceiling suspenders exceeding the specification requirements and being inconvenient to adjust, which is likely to cause non-compliance with the quality acceptance specification requirements. Re-drilling holes will increase costs and delay the construction progress, with low efficiency. Content of the Utility Model

[0003] The technical problem to be solved by this application is to provide a connecting structure between a ceiling suspender and a conversion layer that can adjustably install the ceiling suspender without drilling holes in the conversion layer, and has flexible installation positions, high efficiency, and is easy to ensure the specifications of the position, spacing, and shape of the ceiling suspender.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A connecting structure between a ceiling suspender and a conversion layer, located between a ceiling floor slab 10 and a ceiling 70, is characterized in that: between the ceiling floor slab 10 and the ceiling 70, there is also a conversion layer 20 and a horizontally arranged keel framework; the conversion layer is welded by a plurality of longitudinal angle steel suspenders 21 and horizontal angle steel 22, and each angle steel suspender 21 is installed on the ceiling floor slab 10; between the conversion layer 20 and the keel framework, they are connected by a plurality of connecting pieces 30 and ceiling suspenders 40; each connecting piece 30 is integrally formed by a transverse plate 31 and a vertical plate 32 into a nearly L shape, and two 90° bends are continuously made inward at the end of the vertical plate to form a connecting groove 33 with an opening downward, and the connecting groove 33 is slidably sleeved on the horizontal angle steel 22; through holes are provided on the transverse plate 31 of each connecting piece 30, and the external thread part at the upper end of each ceiling suspender 40 passes upward through the through holes on the corresponding transverse plate 31 and is locked by two nuts respectively located on the upper and lower sides of the transverse plate 31; the upper end of the ceiling suspender 40 abuts against the lower side of the horizontal angle steel 22 to fix the position of the connecting piece 30; the lower end of the ceiling suspender 40 is pre-connected to the keel framework at intervals;

[0006] Each angle steel suspender 21 is installed on the ceiling floor slab 10 through an expansion bolt 23;

[0007] The keel framework is in a horizontal direction and is formed by vertically and cross-connecting a plurality of transverse main keels 50 and secondary keels 60; the lower end of the ceiling suspender 40 is pre-connected to the main keel 50 at intervals;

[0008] The distance from the top end of the angle steel hanger rod 21 to the horizontal angle steel 22 is ≤ 1200 mm;

[0009] The spacing between adjacent main keels is 900 - 1200 mm, and the cantilever end of the main keel is ≤ 300 mm; the spacing between adjacent secondary keels 60 is 300 - 600 mm;

[0010] The ceiling 70 is fixed to the secondary keel 60 by self - tapping screws, and the self - tapping screws are 10 - 15 mm away from the edge of the secondary keel 60 plate;

[0011] A splicing seam of 3 - 5 mm is reserved between adjacent ceilings 70; when using double - layer boards, the second - layer board should be installed with staggered joints from the first - layer board.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: Since the connecting plate can slide on the horizontal angle steel, the installation position can be adjusted arbitrarily, and then the locking nut is tightened. The position of the connecting plate is fixed by the above - mentioned nut and the hanger rod touching the lower part of the horizontal angle steel. It can be seen that the connection structure between the ceiling hanger rod and the conversion layer of the present utility model has adjustable installation, fast speed and high efficiency: The hanger rod and the conversion layer are hung and installed by connecting pieces, without punching holes in the angle steel of the conversion layer, reducing the calculation and punching processes required for angle steel processing and saving time.

Detailed Embodiment

[0018] The technical solutions of the present application will be further described in detail below with reference to the drawings.

[0019] As Figures 1-4As shown in the figure, it is a three-dimensional schematic diagram of the connection structure between the ceiling suspender and the conversion layer of the present utility model. The connection structure between the ceiling suspender and the conversion layer of the present utility model is connected between the ceiling floor slab 10, the keel framework, and the ceiling 70, and includes a conversion layer 20, a connecting member 30, and a ceiling suspender 40. The keel framework is in a horizontal direction and is formed by vertically and cross-connecting a plurality of transverse main keels 50 and secondary keels 60. The distance between adjacent main keels is 900 - 1200 mm, and the cantilever end of the main keel is ≤ 300 mm. The distance between adjacent secondary keels 60 is 300 - 600 mm.

[0020] As Figure 1 and 3 shown, between the ceiling floor slab 10 and the ceiling 70, there is a conversion layer 20 and a keel framework. The conversion layer is formed by welding a plurality of longitudinal angle steel suspenders 21 and horizontal angle steels 22. Each angle steel suspender 21 is installed on the ceiling floor slab 10 through an expansion bolt 23, and the distance from the top end of the angle steel suspender 21 to the horizontal angle steel 22 is ≤ 1200 mm.

[0021] Between the conversion layer 20 and the keel framework, they are connected by a plurality of connecting members 30 and ceiling suspenders 40; each connecting member 30 is integrally formed by a horizontal plate 31 and a vertical plate 32 into a nearly L shape. At the end of the vertical plate, it is continuously bent inward by two 90° to form a connecting groove 33 with an opening downward. The connecting groove 33 is slidably sleeved on the horizontal angle steel 22; a through hole is provided on the horizontal plate 31 of each connecting member 30. The external threaded part at the upper end of each ceiling suspender 40 passes upward through the through hole on the corresponding horizontal plate 31 and is locked by two nuts respectively located on the upper and lower sides of the horizontal plate 31; the upper end of the ceiling suspender 40 abuts against the lower side of the horizontal angle steel 22 to fix the position of the connecting member 30; the lower end of the ceiling suspender 40 is pre-connected to the keel framework at intervals, preferably connected to the main keel 50.

[0022] The installation process is described as follows:

[0023] Step 1: Layout and positioning

[0024] According to the construction layout drawing, measure and layout the lines to determine the installation positions of the conversion layer and the ceiling.

[0025] Step 2: Installation of the conversion layer

[0026] Fix the angle steel suspender on the ceiling floor slab using an expansion bolt, weld and fix the angle steel suspender and the horizontal angle steel, and weld and fix the horizontal angle steel of the conversion layer and the angle steel suspender. The distance between the angle steel suspender and the horizontal angle steel is ≤ @1200 mm.

[0027] Step 3: Installation of the ceiling suspender and the connecting member

[0028] The connecting piece between the ceiling suspension rod and the conversion layer is first assembled and connected to the ceiling suspension rod on the ground. Hang the assembled connecting piece on the horizontal angle steel of the conversion layer, move it left and right to the installation position of the ceiling suspension rod, and tighten the nut after the upper end of the suspension rod abuts against the bottom surface of the horizontal angle steel of the conversion layer.

[0029] Step 4: Installation of the main and auxiliary keels

[0030] The main keel is hung at the lower end of the ceiling suspension rod with a spacing of 900 - 1200 mm. The cantilever end of the main keel should not be greater than 300 mm, otherwise additional suspension rods should be added. The auxiliary keel is installed closely against the main keel, and it can be installed according to the conventional method of the existing technology. The spacing of the auxiliary keel is 300 - 600 mm.

[0031] Step 5: Installation of the ceiling

[0032] The ceiling is fixed to the auxiliary keel with self-tapping screws. The self-tapping screws are 10 - 15 mm away from the edge of the board, with a spacing of 150 - 170 mm, and the screw spacing in the middle of the board is 170 - 200 mm. It is advisable to reserve a 3 - 5 mm joint for the ceiling splicing. When using a double-layer board, the second layer board should be installed with staggered joints from the first layer board.
