Description

Technical Field

[0001] The invention relates to the field of ceiling positioning and installation, and in particular to a method for quickly positioning and installing an indoor multi-point decorative ceiling. Background Art

[0002] The ceiling is a kind of decoration for the top of the indoor environment. In order to enhance the dynamic, spatial and artistic effect of the ceiling, modern ceilings are usually designed as multi-point decorative ceilings. Multi-point decorative ceilings are made by inserting a number of linear LED lights of different lengths and diameters into the ceiling according to the design requirements. By designing the length, brightness, light color and spacing of the linear LED lights, the multi-point decorative ceilings present colorful patterns.

[0003] The existing decorative ceiling positioning and installation method usually involves first using a marker to mark the drilling icon of the decorative ceiling on the ceiling, using a ceiling drill to drill fixing holes on the ceiling for installing linear LED lights, then installing the decorative ceiling to the ceiling through the fixing holes, and then connecting the decorative ceiling to the control circuit located in the ceiling mezzanine.

[0004] In the process of installing the multi-point shaped decorative ceiling on the ceiling, due to the large number of linear LED lights that make up the multi-point shaped decorative ceiling, it is necessary to mark a large number of drilling icons on the ceiling and drill a large number of fixing holes on the ceiling. In order to ensure that the display effect of the multi-point shaped decorative ceiling is consistent with the design drawings, when marking the drilling icons on the ceiling, the position of each drilling icon on the ceiling must be measured. The marking work is cumbersome and is not conducive to the rapid installation of the multi-point shaped decorative ceiling. Therefore, there is still room for improvement. Summary of the invention

[0005] In order to quickly locate and install a multi-point decorative ceiling, the present application provides a method for quickly positioning and installing an indoor multi-point decorative ceiling.

[0006] The present application provides a method for quickly positioning and installing an indoor multi-point decorative ceiling, which adopts the following technical solution: A method for quickly positioning and installing an indoor multi-point decorative ceiling comprises the following steps: Step S1: projecting a marking drawing of the points for installing linear LED lamps on the ceiling onto the imaging material using a projection device; Step S2: randomly selecting at least two points on the shadowing wooden board as distance measuring points, measuring the distance between the distance measuring points, and adjusting the projection device according to the distance between the distance measuring points until the distance between the distance measuring points is consistent with the distance required by the marking drawing; Step S3: According to the marking drawing projected on the imaging material, marking the points projected on the imaging material as drilling points; Step S4: Fixing the shadow material to the installation position of the multi-point decorative ceiling, drilling fixing holes for installing the linear LED lamps into the ceiling according to the drilling points, and then removing the shadow material; Step S5: Install the linear LED lamp on the ceiling through the fixing hole; Step S6: Connect the linear LED lamp to the control circuit.

[0007] By adopting the above technical scheme, a marking drawing of the installation points of the linear LED lamp is projected onto the imaging material using a projection device, and points on at least two imaging wooden boards are randomly selected as distance measuring points. The projection device is adjusted according to the distance between each distance measuring point until the distance between at least two points on the randomly selected imaging material is consistent with the distance between the corresponding points required by the marking drawing. Then, the pattern of the marking drawing can be obtained on the imaging material. By marking the drilling points on the imaging material and then fixing the imaging material to the ceiling, the points for installing the linear LED lamp can be displayed on the ceiling, so that all the drilling icons for installing the linear LED lamp can be displayed on the ceiling at one time, reducing the situation where the position of each drilling icon on the ceiling needs to be measured when marking the drilling icon on the ceiling, thereby reducing the work of measuring the drilling icons, which is beneficial to improving the positioning efficiency of the multi-point shaped decorative ceiling, thereby improving the installation efficiency of the multi-point shaped decorative ceiling. By randomly selecting at least two points on the imaging wooden board as distance measuring points, measuring the distance between each distance measuring point, connecting the two points to form a straight line, the proportion of the pattern projected by the projection equipment on the imaging material is consistent, when the length of the straight line connecting any two distance measuring points on the imaging material is consistent with the distance between the corresponding points required by the marking drawing, the marking drawing projected by the projection equipment on the imaging material is consistent with the pattern of the actual linear LED lamp installation points, the operation is simple, and the positioning efficiency of the multi-point decorative ceiling is further improved.

[0008] Preferably, the shadowing material uses a shadowing wood board.

[0009] By adopting the above technical scheme, the shadowing wooden board is rigid, which reduces the shadowing material being deformed under the action of gravity during the process of fixing the shadowing material to the ceiling with flexible materials such as curtains, resulting in a situation where the spacing of the drilling icons marked on the ceiling is inconsistent with the design requirements. The accuracy of marking the drilling icons on the ceiling is improved, thereby reducing the error between the manufactured multi-point decorative ceiling and the design drawing.

[0010] Preferably, in step S4, marking holes are first drilled at the positions where drilling points are marked on the shading wooden board, and then the shading wooden board is fixed to the installation position of the multi-point decorative ceiling, and then marks are drawn on the marked holes to form drilling icons for drilling fixing holes on the ceiling, and then the shading wooden board is removed, and then fixing holes for installing linear LED lamps are drilled into the ceiling according to the drilling icons.

[0011] By adopting the above technical scheme, a marking hole is first drilled on the shadow wooden board, and then the drilling icon is marked on the ceiling by using the marking hole. Subsequently, the shadow wooden board is removed, and then the fixing holes are drilled on the ceiling. This makes it possible for the shadow wooden board to not be hindered in the process of drilling the fixing holes on the ceiling, thereby reducing the need for the shadow wooden board to be fixed to the ceiling. The shadow wooden board is first drilled through and then the fixing holes are drilled, which causes the shadow wooden board to be easily displaced by the machine for drilling the fixing holes during the process of drilling the fixing holes, causing the fixing holes drilled subsequently to be easily displaced. This improves the accuracy of the position of the installed linear LED lamp, thereby further reducing the error between the manufactured multi-point decorative ceiling and the design drawing.

[0012] Preferably, in step S4, a marking hole is first drilled toward the projection, and then a shadow wooden board is fixed to the installation position of the multi-point decorative ceiling. Then, the marking hole is sprayed with spray paint to form a drilling icon on the ceiling. Then, the shadow wooden board is removed and the fixing holes are drilled.

[0013] By adopting the above technical solution, the marking holes are sprayed with self-spray paint to form drilling icons on the ceiling, which is simple to operate and reduces the use of brushes to paint the marking holes. However, the large number of marking holes leads to low efficiency in adjusting the drilling icons on the ceiling, thereby improving the efficiency of locating the installation position of the linear LED lamp on the ceiling. At the same time, the marking holes are sprayed with self-spray paint, which has a wide spray range and is easier to completely spray the internal space of the marking holes, so that the diameter of the formed drilling icon is consistent with the diameter of the marking hole, reducing the use of brushes to paint the marking holes. The brush and the shadowing wood board are squeezed to make it difficult for the paint overflowing from the brush to completely fill the internal space of the marking hole, resulting in the drilling icon marked with the brush being easy to be elliptical, thereby reducing the use of drilling equipment to drill the fixing hole from the center of the drilling icon. The drilling hole icon is elliptical, which leads to a gap between the drilling position of the fixing hole and the point required by the drawing of the multi-point decorative ceiling, thereby further reducing the error between the manufactured multi-point decorative ceiling and the design drawing.

[0014] Preferably, in step S4, marking holes are first drilled into the shadowing wooden board, and then the shadowing wooden board is placed at the installation position of the multi-point shaped decorative ceiling, and then a number of marking holes are sprayed with spray paint to form a number of drilling icons at the installation position of the multi-point shaped decorative ceiling, and then fixing holes are opened at the positions where the drilling icons are sprayed on the ceiling, and then screws are inserted into the marking holes on the shadowing wooden board that have been sprayed with spray paint and the drilled fixing holes, and then the nuts are screwed into the screws, and then the remaining marking holes are sprayed with spray paint to form the remaining drilling icons on the ceiling, and then the shadowing wooden board is removed, and then the remaining fixing holes are drilled.

[0015] By adopting the above technical solution, several fixing holes are first drilled, and then screws are inserted into the marking holes and fixing holes, and nuts are used to screw in the screws to fix the shadowing wood board to the ceiling, which reduces the situation where construction workers continue to hold up the shadowing wood board during the process of spraying self-spray paint into the marking holes, which is conducive to reducing the workload of construction workers. At the same time, the work of building a fixing frame to fix the shadowing wood board to the ceiling is reduced, and the efficiency of drilling holes in the ceiling is improved. At the same time, several fixing holes are first drilled, and then screws are inserted into the marking holes and fixing holes, and nuts are used to screw in the screws to fix the shadowing wood board to the ceiling. The operation is simple, the tools are simple to use, and no additional holes are drilled in the ceiling, thereby reducing the damage to the ceiling during the temporary fixation of the shadowing wood board.

[0016] Preferably, in step S4, first, mark holes are drilled on the shadowing wooden board, then the shadowing wooden board is placed at the installation position of the multi-point shaped decorative ceiling, and then the mark holes at the four corners and the middle position of the shadowing wooden board are sprayed with spray paint to form drilling icons at the four corners and the middle position of the installation position of the multi-point shaped decorative ceiling, and then fixing holes are opened at the positions where the drilling icons are sprayed on the ceiling, and then screws are inserted into the mark holes at the four corners and the middle position of the shadowing wooden board and the drilled fixing holes, and then the nuts are screwed into the screws, and then the remaining mark holes are sprayed with spray paint to form the remaining drilling icons on the ceiling, and then the shadowing wooden board is removed, and then the remaining fixing holes are drilled.

[0017] By adopting the above technical scheme, fixing holes are first drilled at the four corners and the middle of the installation position of the multi-point shaped decorative ceiling to temporarily fix the four corners and the middle of the shadow wooden board, which is beneficial to improve the stability of the shadow wooden board and reduce the situation where the points used to temporarily fix the shadow wooden board are all set at the four corners of the shadow wooden board, causing the middle position of the shadow wooden board to protrude to the ground under the action of gravity. At the same time, the points used to temporarily fix the shadow wooden board are all set at the middle position of the shadow wooden board, causing the four corners of the shadow wooden board to bend and deform toward the ground under the action of gravity. This reduces the gap between the spacing of the drilling icons marked on the ceiling and the design requirements, further improves the accuracy of marking the drilling icons on the ceiling, and further reduces the error between the manufactured multi-point shaped decorative ceiling and the design drawing.

[0018] Preferably, in step S5, firstly, wires are placed from the interlayer of the ceiling to the floor through the fixing hole, the wires are connected to the linear LED lamp, and then the wires are retracted into the interlayer of the ceiling until the linear LED lamp extends into the fixing hole, and then the linear LED lamp is fixed in the fixing hole.

[0019] By adopting the above technical solution, the work of connecting the wires to the linear LED lights is set on the ground, which reduces the narrow space of the ceiling mezzanine and the limited space for construction workers to move around, and improves the wiring efficiency of the linear LED lights. At the same time, the work of connecting the wires to the linear LED lights is set on the ground, which is conducive to multiple people connecting at the same time, further improving the wiring efficiency of the linear LED lights, thereby further improving the work efficiency of installing multi-point decorative ceilings on the ceiling.

[0020] Preferably, in step S5, the serial numbers of the fixing holes are first marked on the ceiling, and then the corresponding serial numbers of the linear LED lamps are verified according to the serial numbers, and then the wires are placed from the interlayer of the ceiling to the floor through the fixing holes, and the wires are connected to the linear LED lamps, and then the wires are retracted into the interlayer of the ceiling until the linear LED lamps are inserted into the fixing holes, and then the linear LED lamps are fixed in the fixing holes.

[0021] By adopting the above technical solution, the serial number of the fixing hole is marked first, and then the wire is discharged to the floor through the fixing hole, which reduces the number of fixing holes drilled on the ceiling, which leads to incorrect connection points between the linear LED lamp and the control circuit through the wire, thereby reducing the situation where the linear LED lamp has incorrect lighting time and color. At the same time, when the linear LED lamp is installed, it is necessary to check whether the wiring is correct, which is conducive to improving the work efficiency of detecting the linear LED lamp circuit.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting up a projector to project a marking drawing onto the imaging material first, and then using the marking drawing projected onto the imaging material to make drilling points on the imaging material, and then using the drilling points and the imaging material to mark drilling icons on the ceiling, all drilling icons for installing linear LED lights can be displayed on the ceiling at one time, reducing the need to measure the position of each drilling icon on the ceiling when marking a drilling icon on the ceiling, thereby reducing the work of measuring drilling icons, which is beneficial to improving the positioning efficiency of multi-point decorative ceilings, thereby improving the installation efficiency of multi-point decorative ceilings.

[0023] 2. By setting the shadow board, mark hole and self-painted spray mark hole to form a drilling icon, the accuracy of the position of the linear LED lamp is improved, thereby reducing the error between the multi-point decorative ceiling and the design drawing.
