DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-4This application is described in further detail.

[0024] The present application embodiment first discloses a ceiling keel for a building, referring to Figure 1 A building ceiling keel includes a vertically arranged hanger rod 1, a horizontally arranged main keel 2, and a horizontally arranged secondary keel 21. The surface of the hanger rod 1 is provided with a thread in the shape of a screw rod 322. The top end of the hanger rod 1 is fixed to the ceiling, and the bottom end of the hanger rod 1 is bolted to the main keel 2 and fixed to the main keel 2 by a nut; one main keel 2 corresponds to multiple hangers 1, and the multiple hangers 1 are evenly spaced along the length direction of one main keel 2; the secondary keel 21 is perpendicular to the main keel 2 and is clamped to the bottom side of the main screw rod 322. The bottom side of the main screw rod 322 is provided with a groove for adapting and clamping the secondary keel 21. The top side of the secondary keel 21 and the bottom side of the multiple main keels 2 are fixed by bolts.

[0025] The present application embodiment further discloses a building ceiling keel auxiliary installation device. Figure 2 A device for auxiliary installation of ceiling keels for buildings includes a frame body 3, which includes two vertically arranged frame rods 31. The two frame rods 31 are arranged vertically to form the frame rod 31 together; the two frame rods 31 are provided with slide grooves 32 along the opposite sides of the main parts of the two frame rods 31, and the slide grooves 32 extend to the top and bottom ends of the frame rods 31. A motor 321 is vertically arranged on the outer wall of the top of the slide groove 32. The motor 321 is arranged vertically downward, and its output shaft passes through the top wall of the slide groove 32. A screw rod 322 is rotatably connected in the slide groove 32. The screw rod 322 is vertically arranged and parallel to the main part of the frame rod 31. The top of the screw rod 322 is connected to the motor 32 The output shaft end of 1 is fixedly connected, so that the motor 321 drives the screw rod 322 to rotate. The screw rod 322 is threadedly connected with a slider, which is slidably connected in the slide groove 32. As the screw rod 322 rotates, the slider vertically rises and falls along the slide groove 32; the opposing sides of the two sliders are hinged with support arms 33, one end of the two support arms 33 is hinged with the slider, and the other end is a free end, which rotates around the hinge point to a horizontal or vertical state. When the two support arms 33 rotate to a vertical state, they fit the frame rod 31; the two support arms 33 are arranged in a vertical plane, so that when the two support arms 33 rotate to a horizontal state, the two support arms 33 can be located in a straight line.

[0026] Reference Figure 2 and Figure 3 In this embodiment, the thread on the screw 322 is a bidirectional thread, and the screw 322 rotates in one direction.

[0027] In this embodiment, the support arm 33 is set corresponding to the main keel 2. When the support arm 33 is in a horizontal state, it can be used to lift the main keel 2. The construction workers move the single main keel 2 to the two support arms 33, install the suspension rod 1 at equal intervals, and then the motor 321 rotates to drive the support arm 33 to rise until the suspension rod 1 on the main keel 2 contacts the ceiling. When the height is suitable and the support arm 33 is stable, the installation efficiency of the suspension rod 1 is improved.

[0028] Reference Figure 2 and Figure 3 The bottom ends of the two frame rods 31 are formed with hinge blocks on the sides facing each other, and the hinge blocks are hinged with bottom arms 34 on the sides facing each other. One end of the bottom arm 34 is hinged with the hinge block, and the other end is provided with a clamping structure. The bottom arm 34 rotates around the hinge block to a horizontal or vertical state. When the bottom arm 34 rotates to a horizontal state, the bottom arm 34 serves as a supporting part at the bottom of the frame body 3. After the two bottom arms 34 rotate to a horizontal state, the clamping structures provided at the opposite ends thereof can make the two bottom arms 34 dock, and the two frame rods 31 are joined as a whole, that is, the two frame rods 31 are joined into the frame body 3. The bottom end of the frame rod 31 is rotatably connected with a roller 323 inside the slide slot 32. The hub surface of the roller 323 is horizontally arranged, and the hub edge of the roller 323 extends out of the frame rod 31. Correspondingly, the side wall of the slide slot 32 is horizontally provided with a through groove corresponding to the roller 323, so that the hub can effectively extend out of the slide slot 32.

[0029] Reference Figure 2 and Figure 3 The clamping structure includes a clamping block formed at an end of a bottom wall and a groove adapted to the clamping block. When the bottom arm 34 is in a horizontal state, the two rack rods 31 slide toward each other so that the ends of the two bottom arms 34 are plugged in.

[0030] Reference Figure 3 and Figure 4 The roller 323 is coaxially arranged with the screw rod 322, and a protruding structure is formed on the central part of the hub surface of the roller 323, and the protruding structure is arranged corresponding to the bottom end of the screw rod 322. The bottom end of the screw rod 322 and the top of the protruding structure of the hub of the roller 323 are provided with a snap-in groove 324, and the two snap-in grooves 324 are arranged in a vertical plane. The screw rod 322 and the hub of the roller 323 are penetrated in the horizontal direction of the snap-in groove 324. If the construction personnel snap a metal plate or a metal block onto the bottom end of the screw rod 322 and the hub of the roller 323, the screw 322 and the hub of the roller 323 are combined into one, so that the screw 322 drives the hub of the roller 323 to rotate; the relevant personnel dismantle the metal plate that plays a connecting role, and the rotation of the screw 322 does not drive the hub of the roller 323 to rotate, and the two are separated.

[0031] Reference Figure 2 and Figure 3 In the horizontal state, the bottom sides of the two bottom arms 34 facing each other are rotatably connected with intermediate rollers 341323 for supporting the bottom arms 34 in the horizontal state.

[0032] Reference Figure 2 and Figure 3 A support plate 35 is horizontally formed on the back side of the main parts of the two frame rods 31, and a vertically arranged track steel 351 is abutted on the support plate 35. One side of the track steel 351 is grooved along the length direction, so that the track steel 351 is in the shape of a channel steel, and the top edge of the side wall of one side of the track steel 351 is higher than the top edge of the side wall of the other side; a clamping strip is formed on the frame rod 31, and both ends of the clamping strip are fixedly connected to the frame rod 31. A spacing is set between the main part of the clamping strip and the main body of the frame rod 31, so that the clamping strip is door-shaped as a whole, and the bottom end of the track steel 351 is connected to the support plate 35, and the main part will be clamped on the frame rod 31.

[0033] Therefore, the relevant personnel remove the track steel 351 from the frame rod 31, place the track steel 351 horizontally on the ground on the opposite sides of the two frame rods 31, abut the bottom of the groove of the track steel 351 with the roller 323, and place the edge of the side with a larger height of the side wall of the track steel 351 horizontally at the bottom end of the frame rod 31 to support the frame rod 31, and the edge of the side with a smaller height of the side wall of the track steel 351 abuts the edge of the frame rod 31. In this state, the roller 323 rolls along the bottom wall of the track steel 351, and with the support of the middle rollers 341323, the frame body 3 moves horizontally.

[0034] The implementation principle of the auxiliary installation device for building ceiling keels in the embodiment of the present application is: the construction personnel carry the rack 31 to the construction area, unfold the bottom arm 34 and the support arm 33, slide the two racks 31 toward each other, and connect the bottom arms 34 on the two racks 31.

[0035] In this embodiment, the clamping block on one bottom arm 34 is clamped with the groove on the other bottom arm 34, so that the two frame rods 31 are connected as a whole. It should be noted that the end of the clamping block in this embodiment is horizontally clamped. This clamping method can provide bottom wall restriction in the vertical plane to prevent the bottom arm 34 from rotating vertically after unfolding.

[0036] The construction personnel dismantle the rail steel 351 and lay the corresponding roller 323 horizontally so that the roller 323 abuts against the bottom wall of the rail steel 351 .

[0037] The construction workers place the main keel 2 on the two bottom arms 34 and install the main keel 2 and the suspension rod 1. After the installation of the main keel 2 and the suspension rod 1 is completed, the motor 321 drives the screw rod 322 to rotate, lifts the support arm 33, moves the main keel 2 upward, and installs the suspension rod 1 on the ceiling.

[0038] The construction personnel also place a metal plate in the snap-in groove 324 at the bottom of the screw 322 and the top of the hub to engage the screw 322 with the hub. The screw 322 rotates, driving the roller 323 to roll, thereby causing the roller 323 to roll along the bottom wall of the track steel 351, driving the frame 3 to roll horizontally.

[0039] Under the action of the bidirectional thread, the support arm 33 rolls on the roller 323 and descends at the same time, repeating the next installation cycle.

[0040] After the construction is completed, the relevant personnel put away the support arm 33 and the bottom arm 34.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
