Description

Technical Field

[0001] The present invention relates to the field of building construction, and in particular to a ceiling leveling device for building construction. Background Art

[0002] A ceiling refers to a kind of decoration for the interior top of a house, which can cover some irregular shapes of the original ceiling, conceal some cables running through the ceiling, facilitate the installation of some lamps, and can also be made into some shapes, thus making the ceiling more beautiful. During the installation of the ceiling, it is necessary to vertically install suspenders on the top plate first, then determine the horizontal height of the ceiling, and then install and fix the light steel keel.

[0003] In the existing construction method, during the installation and fixation of the light steel keel, since the construction worker needs to hold the light steel keel with one hand and tighten the nut with the other hand, it is difficult to keep the position of the light steel keel unchanged while tightening the nut, resulting in a deviation between the installation position of the light steel keel and the pre-designed height, and the horizontal height of the light steel keel is not accurate enough. Moreover, when using the current construction method to install the light steel keel, it is not convenient to adjust the left and right positions of the light steel keel, which affects the subsequent construction. Summary of the Invention

An inclined surface rod is fixedly connected to the side of each support plate, and the two inclined surface rods are both located below the light steel keel.

[0009] Optionally, a left - right leveling mechanism is further included. The left - right leveling mechanism is arranged on the sliding rod. The left - right leveling mechanism includes a pushing frame, a fixed rod, a slotted frame, a moving column, and a small spring. A pushing frame is fixedly connected to one end of each sliding rod close to the screw rod column. A fixed rod is slidably connected to each pushing frame. A slotted frame is slidably connected to each support plate, and the fixed rod is fixedly connected to the slotted frame. Two moving columns are slidably connected to the upper part of each slotted frame, and the two moving columns connected to each slotted frame are symmetrically arranged. The four moving columns are all located below the light steel keel. A small spring is fixedly connected between the two moving columns connected to each slotted frame.

[0010] Optionally, a limit leveling mechanism is further included. The limit leveling mechanism is arranged on the support plate. The limit leveling mechanism includes an inclined surface frame, a large spring, a slotted guide frame, and a limit rod. An inclined surface frame is slidably connected to each support plate.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. In actual use, construction workers first use an infrared level to project infrared light onto the required horizontal height of the ceiling. Then, the construction workers rotate the adjustment knob counterclockwise so that the positioning plate moves upward to the same height as the infrared light. At this time, the two positioning plates are on the same horizontal plane. The construction workers stop rotating the adjustment knob. Subsequently, the construction workers start the electric slide rail, so that the support leveling frame moves upward to contact the light steel keel. When the support leveling frame continues to move upward, it will drive the light steel keel to move upward, so that the light steel keel contacts the lower surface of the positioning plate. Then, the construction workers turn off the electric slide rail. Then, the construction workers tighten the nut above the light steel keel downward and tighten the nut below the light steel keel upward, thereby fixing the light steel keel. By first fixing the light steel keel at a preset horizontal height through the positioning plate and the support leveling frame, and then the construction workers tighten the nuts to fix the light steel keel, the horizontal height of the light steel keel is made more accurate.

[0015] 2. When the sliding rod moves towards the lead screw column, it will drive the pushing frame, the fixed rod, the grooved frame, the moving column and the small spring to move upward. When the moving column moves upward, it will contact the light steel keel. Then, the pushing frame will squeeze the two moving columns to move away from each other, and the small spring is stretched. When the two moving columns move away from each other, they will squeeze the light steel keel, thus making it more convenient to adjust the left and right positions of the light steel keel, further making the position of the light steel keel more accurate and facilitating subsequent construction.

[0016] 3. When the moving rod moves towards the lead screw column, it will contact the inclined plane frame. When the moving rod continues to move towards the lead screw column, it will squeeze the inclined plane frame to move downward, and the large spring is compressed. When the inclined plane frame moves downward, it will drive the two limiting rods to move downward. During the process of the two limiting rods moving downward, the grooved guiding frame will squeeze the two limiting rods, so that the two limiting rods move towards each other. When the two limiting rods move towards each other, they will contact the light steel keel, and the two limiting rods will squeeze the light steel keel, thereby further adjusting the horizontal position of the light steel keel and further making the position of the light steel keel more accurate.

Detailed implementation manners

[0030] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below with reference to specific drawings.

[0031] Embodiment 1

[0032] A ceiling leveling device for building construction, as Figures 1-9As shown in the figure, it includes a nut 12, an adjusting mechanism, and a height leveling mechanism. Two suspension rods 11 are fixedly connected to the lower surface of the top plate 1. A light steel keel 2 is sleeved between the two suspension rods 11. Two nuts 12 are threadedly connected to each suspension rod 11, and the two nuts 12 on each suspension rod 11 are respectively located above and below the light steel keel 2. Connecting brackets 3 are bolted to both ends of the light steel keel 2. The adjusting mechanism is placed on the ground and is used to adjust the height. The height leveling mechanism is arranged on the adjusting mechanism.

[0033] The adjusting mechanism includes a support and guide seat 41, a lead screw column 42, an adjusting knob 43, a support plate 44, and a positioning plate 45. The two support and guide seats 41 are placed on the ground. The interior of the support and guide seat 41 is a hollow structure. A lead screw column 42 is slidably connected to the upper part of each support and guide seat 41. An adjusting knob 43 is threadedly connected to each lead screw column 42, and the adjusting knob 43 is rotatably connected to the top end of the support and guide seat 41. A support plate 44 is bolted to the upper part of each lead screw column 42, and the support plate 44 is located below the light steel keel 2. Two sliding grooves are formed in the support plate 44, and the sliding grooves of the support plate 44 are divided into an inclined surface part and a horizontal part. A positioning plate 45 is bolted to the top of each lead screw column 42. The positioning plate 45 is used to fix the horizontal height of the light steel keel 2, and the positioning plate 45 is located above the light steel keel 2.

[0034] The height leveling mechanism includes an electric slide rail 51, a moving rod 52, a sliding rod 53, a support and leveling frame 54, and an inclined surface rod 56. An electric slide rail 51 is riveted to the upper surface of each support plate 44. A moving rod 52 is slidably connected to each electric slide rail 51. A sliding rod 53 is slidably connected to each moving rod 52, and the sliding rod 53 is slidably connected to the support plate 44. The lower end of the sliding rod 53 is located in the inclined surface part of the two sliding grooves on the support plate 44. A support and leveling frame 54 is slidably connected to the top of each sliding rod 53. The support and leveling frame 54 is used to lift the light steel keel 2 until it contacts the lower surface of the positioning plate 45. An inclined surface rod 56 is bolted to the side of each support plate 44, and the two inclined surface rods 56 are both located below the light steel keel 2.

[0035] In actual use, construction workers first use an infrared level to project infrared light onto the required horizontal height of the ceiling. Then, the construction workers rotate the adjustment knob 43 counterclockwise. The counterclockwise rotation of the adjustment knob 43 drives the lead screw column 42 to move upward. The upward movement of the lead screw column 42 drives the support plate 44, the positioning plate 45, the electric slide rail 51, the moving rod 52, the sliding rod 53, the support leveling frame 54, and the inclined surface rod 56 to move upward. When the positioning plate 45 moves upward to the same height as the infrared ray, the two positioning plates 45 are on the same horizontal plane. The construction workers stop rotating the adjustment knob 43, and the support plate 44, the positioning plate 45, the electric slide rail 51, the moving rod 52, the sliding rod 53, the support leveling frame 54, and the inclined surface rod 56 no longer move upward. Subsequently, the construction workers start the electric slide rail 51. The electric slide rail 51 drives the moving rod 52, the sliding rod 53, and the support leveling frame 54 to move in the direction close to the lead screw column 42. The support plate 44 will squeeze the sliding rod 53 to move upward. The upward movement of the sliding rod 53 will drive the support leveling frame 54 to move upward. The sliding rod 53 will continue to move to the horizontal part of the sliding groove of the support plate 44. Subsequently, the sliding rod 53 and the support leveling frame 54 no longer move upward. The sliding rod 53 and the support leveling frame 54 continue to move in the direction close to the lead screw column 42. The movement of the support leveling frame 54 in the direction close to the lead screw column 42 will contact the inclined surface part of the inclined surface rod 56. The support leveling frame 54 continues to move in the direction close to the lead screw column 42, and the inclined surface rod 56 will squeeze the support leveling frame 54, causing the support leveling frame 54 to move upward to contact the light steel keel 2. The support leveling frame 54 continues to move upward and will slide on the lower surface of the light steel keel 2. And the upward movement of the support leveling frame 54 will drive the light steel keel 2 to move upward. The upward movement of the light steel keel 2 will contact the lower surface of the positioning plate 45. At this time, the support leveling frame 54 moves to no longer contact the inclined surface part of the inclined surface rod 56, and the inclined surface rod 56 no longer squeezes the support leveling frame 54. The support leveling frame 54 no longer drives the light steel keel 2 to move upward. The support leveling frame 54 continues to slide on the lower surface of the light steel keel 2. Subsequently, the construction workers turn off the electric slide rail 51. The electric slide rail 51 no longer drives the moving rod 52, the sliding rod 53, and the support leveling frame 54 to move in the direction close to the lead screw column 42. At this time, the light steel keel 2 is at the horizontal height preset by the construction workers. Then, the construction workers tighten the nut 12 above the light steel keel 2 downward and tighten the nut 12 below the light steel keel 2 upward, thereby fixing the light steel keel 2. By first fixing the light steel keel 2 at the preset horizontal height through the positioning plate 45 and the support leveling frame 54, and then the construction workers tighten the nut 12 to fix the light steel keel 2, the horizontal height of the light steel keel 2 is made more accurate;After the fixing of the light steel keel 2 is completed, the construction worker starts the electric slide rail 51 again. The electric slide rail 51 will drive the moving rod 52, the sliding rod 53 and the support leveling frame 54 to move away from the lead screw column 42. When the support leveling frame 54 moves away from the lead screw column 42, it will be separated from the contact with the inclined plane rod 56. The inclined plane rod 56 no longer presses the support leveling frame 54, and the support leveling frame 54 will move downward. The sliding rod 53 continues to move away from the lead screw column 42 to the inclined surface part of the sliding groove on the support plate 44. The support plate 44 will press the sliding rod 53, so that the sliding rod 53 will move downward while moving away from the lead screw column 42. The downward movement of the sliding rod 53 will drive the support leveling frame 54 to move downward and reset. After the moving rod 52, the sliding rod 53 and the support leveling frame 54 are reset, the construction worker turns off the electric slide rail 51.;

[0036] Embodiment 2

[0037] On the basis of Embodiment 1, as Figures 8-10 shown, it further includes a left-right leveling mechanism. The left-right leveling mechanism is arranged on the sliding rod 53. The left-right leveling mechanism includes a pushing frame 61, a fixed rod 62, a grooved frame 63, a moving column 64 and a small spring 65. One end of each sliding rod 53 close to the lead screw column 42 is bolted with a pushing frame 61. Each pushing frame 61 is slidably connected with a fixed rod 62. Each support plate 44 is slidably connected with a grooved frame 63, and the fixed rod 62 and the grooved frame 63 are bolted. Two moving columns 64 are slidably connected to the upper part of each grooved frame 63. The moving columns 64 are used for adjusting the left-right position of the light steel keel 2. The two moving columns 64 connected to each grooved frame 63 are symmetrically arranged, and all four moving columns 64 are located below the light steel keel 2. A small spring 65 is connected between the two moving columns 64 connected to each grooved frame 63 through a hook.

[0038] When the sliding rod 53 moves towards the lead screw column 42, it will drive the push frame 61 to move towards the lead screw column 42. When the sliding rod 53 moves upward, it will drive the push frame 61 to move upward. When the push frame 61 moves upward, it will drive the fixed rod 62, the slotted frame 63, the moving column 64 and the small spring 65 to move upward. When the moving column 64 moves upward and contacts the light steel keel 2, the sliding rod 53 just moves to the horizontal part of the sliding groove on the support plate 44, and the push frame 61 no longer drives the fixed rod 62, the slotted frame 63, the moving column 64 and the small spring 65 to move upward. When the push frame 61 moves towards the lead screw column 42, it will contact the lower parts of the two moving columns 64, and the push frame 61 will squeeze the two moving columns 64 to move away from each other, and the small spring 65 is stretched. When the two moving columns 64 move away from each other, they will squeeze the light steel keel 2, so as to more conveniently adjust the left and right positions of the light steel keel 2, make the position of the light steel keel 2 more accurate, and facilitate subsequent construction. After the sliding rod 53 stops sliding, the sliding rod 53 no longer drives the push frame 61 to move towards the lead screw column 42; when the sliding rod 53 moves away from the lead screw column 42, it will drive the push frame 61 to move away from the lead screw column 42. When the push frame 61 moves away from the lead screw column 42, it will disengage from the contact with the two moving columns 64, and the small spring 65 will reset. When the small spring 65 resets, it will drive the two moving columns 64 to move and reset towards each other. After the sliding rod 53 moves to the inclined part of the sliding groove on the support plate 44, the sliding rod 53 moves downward and drives the push frame 61 to move downward and reset, and the push frame 61 will drive the fixed rod 62, the slotted frame 63, the moving column 64 and the small spring 65 to move downward and reset.

[0039] Embodiment 3

[0040] On the basis of Embodiment 2, as Figure 10 and Figure 11 shown, it further includes a limit leveling mechanism. The limit leveling mechanism is arranged on the support plate 44. The limit leveling mechanism includes an inclined plane frame 71, a large spring 72, a slotted guide frame 73 and a limit rod 74. Each support plate 44 is slidably connected with an inclined plane frame 71. A large spring 72 is connected between each inclined plane frame 71 and the positioning plate 45 through a hook. The upper surface of each positioning plate 45 is connected with a slotted guide frame 73 by rivets. Two guide grooves are formed in each slotted guide frame 73. Two limit rods 74 are slidably connected to the upper part of each inclined plane frame 71, and the two limit rods 74 connected to the upper part of each inclined plane frame 71 are symmetrically arranged. The four limit rods 74 are respectively located in the four guide grooves of the two slotted guide frames 73.

[0041] When the moving rod 52 moves toward the direction approaching the screw column 42, it will contact the inclined plane frame 71. When the moving rod 52 continues to move toward the direction approaching the screw column 42, it will squeeze the inclined plane frame 71 to move downward. The large spring 72 is compressed, and the downward movement of the inclined plane frame 71 will drive the two limit rods 74 to move downward. During the downward movement of the two limit rods 74, the slotted guide frame 73 will squeeze the two limit rods 74, so that the two limit rods 74 move in a direction approaching each other. The two limit rods 74 move in a direction approaching each other and contact the light steel keel 2. The two limit rods 74 will squeeze the light steel keel 2 , thereby further adjusting the horizontal position of the light steel keel 2, making the position of the light steel keel 2 more accurate; the moving rod 52 moves in a direction away from the screw rod column 42 to break away from the contact with the inclined plane frame 71, and the large spring 72 is reset. The reset of the large spring 72 will drive the inclined plane frame 71 to move upward and reset. The upward movement of the inclined plane frame 71 drives the two limit rods 74 to move upward, and the slotted guide frame 73 will squeeze the two limit rods 74, so that the two limit rods 74 move in a direction away from each other. The two limit rods 74 move in a direction away from each other and break away from the contact with the light steel keel 2 and reset.

[0042] Example 4

[0043] On the basis of Example 1, Figure 2 and Figure 7 As shown, it also includes a stabilizing rod 81 and a small screw 82. Each of the upper parts of the screw columns 42 is connected to two small screws 82 by threads, and the two small screws 82 connected to each of the screw columns 42 are symmetrically arranged, and a stabilizing rod 81 is slidably connected between each two of the small screws 82. The small screw 82 is used to make each of the stabilizing rods 81 contact with the upper part of the screw columns 42, and the top of each of the stabilizing rods 81 contacts with the lower surface of the top plate 1. The small screw 82 is used to make the stabilizing rod 81 close to the lower surface of 1.

[0044] After the construction workers complete the height adjustment of the positioning plate 45, the construction workers slide the stabilizing rod 81 upward so that the upper end of the stabilizing rod 81 is in close contact with the lower surface of the top plate 1. Then the construction workers tighten the two small screws 82 to make the stabilizing rod 81 more stable, thereby making the equipment more stable, and thus making the fixed position of the light steel keel 2 more accurate. After completing the fixation of the light steel keel 2, the construction workers loosen the two small screws 82, and then slide the stabilizing rod 81 downward so that the upper end of the stabilizing rod 81 is out of contact with the lower surface of the top plate 1.

[0045] Example 5

[0046] On the basis of Example 1, Figure 1 and Figure 12As shown, it further includes an optical fiber light guide bar 9. Two optical fiber light guide bars 9 are connected to each of the positioning plates 45 by rivets. The optical fiber light guide bar 9 is used to reflect the infrared light emitted by the infrared level, and the two optical fiber light guide bars 9 connected to each positioning plate 45 are symmetrically arranged.

[0047] When the construction worker adjusts the height of the positioning plate 45, the movement of the positioning plate 45 drives the movement of the optical fiber light guide bar 9. The optical fiber light guide bar 9 on the positioning plate 45 can reflect the infrared light emitted by the infrared level, which is convenient for the construction worker to observe, and thus convenient for the construction worker to adjust the height of the positioning plate 45.
