Description

Technical Field

[0001] This invention belongs to the field of decoration and construction technology, specifically relating to the engineering construction method of a colored fishing line cross-shaped wall positioning ceiling device. Background Technology

[0002] Ceiling decoration is part of interior decoration. Since there are many devices that need to be installed on the ceiling, such as air ducts and fire sprinklers, it is necessary to pre-position these devices during the decoration process to avoid dimensional deviations during subsequent installation. The existing positioning methods usually use ground marking technology or floor marking technology.

[0003] Ground marking technology utilizes the straight-line properties of a chalk line to imprint ink onto the ground, creating straight lines that serve as references for positioning ceiling equipment. Construction workers determine the horizontal projection positions of each ceiling device on the ground according to the design drawings, and then use the grid formed by the ground markings to determine the vertically corresponding device positions. However, ground marking technology has the following problems: 1. Ground markings are easily damaged, leading to repeated construction. During interior decoration and renovation, various trades frequently work together. The ground, as the main construction passage and operating area, is easily damaged by personnel movement, material handling, and other construction operations. Once the markings are damaged, construction workers cannot accurately determine the positioning of the ceiling equipment and must redo the marking process. This not only wastes a lot of time and labor costs but also delays the construction schedule; 2. Ground markings can only determine the horizontal projection positions of the ceiling equipment; they cannot accurately reflect the installation height information. In actual construction, the finished ceiling height may vary due to design requirements or actual site conditions. Relying solely on ground markings cannot guarantee a precise match between the equipment installation height and the finished ceiling surface.

[0004] Floor slab marking technology utilizes a laser line projector to emit horizontal or vertical laser lines, creating clearly visible straight lines on the floor slab. A plumb line is used to assist in determining the vertical direction. Through the vertical force of gravity, the accuracy of the marking lines is ensured. Construction workers, according to design requirements, use the laser lines projected by the laser line projector to determine the position of equipment on the floor slab, and then use the plumb line to confirm the vertical direction, thus locating the position of the ceiling equipment on the vertical plane. Disadvantages of floor slab marking technology: 1. The marked positions are easily obstructed later. After the installation of various ceiling equipment is completed, the marked positions on the floor slab are often blocked by equipment, pipelines, etc. 1. When equipment debugging, maintenance, or subsequent construction requires reference to positioning information, obscured chalk lines cannot provide effective positioning basis, causing great inconvenience to construction; 2. Similar to ground chalk lines, although floor chalk lines can determine the position in the vertical direction, they are not precise enough for determining the equipment installation height. In actual construction, floor chalk lines mainly focus on determining the position of the equipment on the vertical plane, lacking effective means for fine-tuning the equipment installation height and precise coordination with the finished ceiling surface; 3. Inconvenient operation and low efficiency. When performing chalk line operation on the floor, construction personnel need to carry equipment and climb to the floor position. The operating space is relatively narrow, and care must be taken to keep the equipment stable, making the operation process cumbersome. At the same time, floor chalk lines are greatly restricted by the construction environment. Factors such as the flatness of the floor and the accumulation of debris can affect the chalk line effect, resulting in low construction efficiency.

[0005] To address the aforementioned technical problems, this invention proposes an engineering construction method for a colored fishing line cross-shaped wall positioning ceiling device, overcoming the shortcomings of the two positioning methods mentioned above during the construction process. Summary of the Invention

[0006] The purpose of this invention is to provide an engineering construction method for a colored fishing line cross-shaped wall positioning ceiling device, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an engineering construction method for a colored fishing line cross-shaped wall positioning ceiling device, comprising the following steps: S1: Project preparation, which includes hardware equipment preparation and construction preparation; S2: Fixed installation of colored fishing line; S3: Equipment positioning and installation; S4: Installation and maintenance of colored fishing lines; S5: Construction method protection, which includes source protection and process protection.

[0008] Furthermore, the hardware preparation in S1 includes the following hardware: Colored fishing line: Use high-tenacity, highly recognizable colored fishing line (such as red or yellow), with a diameter of 0.5-1mm; Fixing devices: Use small expansion bolts, strong double-sided tape, or U-shaped nails as fishing line fixing components; Height positioning tools: Use high-precision laser levels, measuring tapes, and other tools.

[0009] Furthermore, the connection relationships of the hardware are as follows: Colored fishing line and fixing device: According to the design requirements, mark the fixing points of the fishing line on the wall. Use expansion bolts, double-sided tape or U-shaped nails to fix one end of the fishing line to the wall and extend the other end to the other end of the wall in the corresponding positioning area. Adjust the tension of the fishing line to ensure that the fishing line is horizontal, straight and without slack. Height positioning tools and colored fishing line: Before construction, use a laser level to project a horizontal laser line on the wall that is at the same height as the finished ceiling surface. Using this as a reference, use a tape measure to measure and mark the fixing points of the fishing line to ensure that the fixing height of the fishing line coincides with the laser line, so as to achieve accurate positioning of the fishing line height.

[0010] Furthermore: the construction preparation in S1 includes the following steps: Based on the design drawings, determine the projection positions of equipment such as ceiling sprinklers and air vents on the wall. Use a laser level to project a horizontal laser line onto the wall at the same height as the finished ceiling surface, which will serve as the height reference for fixing the fishing line.

[0011] Furthermore: the fixed installation of the colored fishing line in S2 includes the following steps: At the wall position corresponding to the equipment positioning point, fix the colored fishing line with expansion bolts, double-sided tape or U-shaped nails to form a horizontal positioning line; If it is necessary to determine the intersection point, repeat the above operation in the vertical direction within the same horizontal plane so that the two fishing lines are in a cross shape in space.

[0012] Furthermore: the device positioning and installation in S3 includes the following steps: Using the cross intersection of the colored fishing line as a reference, determine the installation point of the ceiling equipment at the corresponding vertically upward position; Construction workers install the equipment according to the intersection of the colored fishing lines.

[0013] Furthermore: the construction and maintenance of the colored fishing line in S4 includes the following steps: During construction, since the colored fishing line is fixed high on the wall, it is not easily affected by ground construction activities. If the fishing line becomes loose or shifts, it can be readjusted and fixed through the fixing device to ensure accurate positioning throughout the entire construction process.

[0014] Furthermore: the source protection in S5 includes the following steps: Optimize fishing line selection and configuration: Use thicker fishing line specifications. Depending on the complexity of the construction environment, you can choose high-strength colored fishing line with a diameter of 1-1.2mm. Enhance the stability of the fixing device: Select high-strength, adaptable fixing parts for different wall substrates; Optimized fishing line tension control: An adjustable fixing structure is adopted to precisely control the tension of the fishing line, avoiding the problems of tangling when too loose and breaking when too tight, ensuring that the fishing line always remains straight and stable.

[0015] Furthermore: the process protection in S5 includes the following steps: Clear signage and dynamic maintenance: Add visual warning signs, install colored plastic sheet signs, and hang colored plastic sheets at intervals of 50-80cm on the fishing line at the cross-shaped positioning line and key extension sections; Add warning signs to the designated area: Post warning signs on the walls and floor of the fishing line positioning area; Regular inspection frequency: A comprehensive inspection shall be carried out once before construction begins, once after lunch break, and once before construction ends each day. Quick repair process: If the fishing line becomes loose, tighten it again in time using the adjustable fastener. If the fishing line is partially worn but not broken, add temporary fixing points on both sides of the worn area and replace the section of fishing line. If the fastener is loose, reinforce it or change the fixing method according to the wall material to ensure that the positioning accuracy is not affected.

[0016] Furthermore, the process protection in S5 is carried out throughout the entire construction process.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. By fixing the fishing line to the wall, the fishing line is positioned relatively high and is not easily touched by construction activities, effectively avoiding the problem of repeated construction caused by the damage of the positioning line in the ground-based line marking technology; 2. This invention fixes the colored fishing line to the wall, and the height of the fishing line is consistent with the height of the finished ceiling surface. The accurate height and horizontal position of the equipment installation can be directly determined by the intersection of the fishing lines, which solves the problem that the height cannot be accurately determined by the ground line. 3. This invention utilizes a wall-mounted fishing line for positioning. The fishing line is exposed on the wall and will not be obstructed by ceiling equipment. It is clearly visible throughout the entire construction process and can provide accurate reference for equipment positioning at any time, overcoming the problem of obstruction of the points in the later stages of floor slab marking. 4. This invention, by fixing the wall fishing line at the same height as the finished ceiling surface, can directly and accurately determine the installation height of the equipment, overcoming the problem of inaccurate height positioning by floor slab chalk lines; 5. This invention uses a wall-mounted fishing line method, allowing construction workers to operate on the wall, providing a spacious operating space and a relatively simple construction environment, which greatly improves construction efficiency and makes operation more convenient. Attached Figure Description

[0018] Figure 1 This is a flowchart illustrating the construction process of the present invention. Figure 2 This is a node diagram of the present invention; Figure 3 This is a schematic diagram of the installation of the colored fishing line of the present invention.

[0019] The attached diagram lists the components represented by each number as follows: 1. Colored fishing line; 2. Fixing device; 3. Equipment location. Detailed Implementation

[0020] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0021] like Figure 1-3 As shown, the construction method for the colored fishing line cross-shaped wall positioning ceiling device includes the following steps: S1: Project preparation, which includes hardware equipment preparation and construction preparation; S2: Fixed installation of colored fishing line 1; S3: Equipment positioning and installation; S4: Colored fishing line 1 installation and maintenance; S5: Construction method protection, which includes source protection and process protection.

[0022] Based on the above steps: This construction method innovatively adopts a positioning method of fixing colored fishing line 1) on the wall. The height of the fishing line is consistent with the finished ceiling surface. The horizontal and height positions of the equipment installation are accurately determined by cross-shaped intersections. This method effectively avoids the positioning line being damaged by construction activities. It is clearly visible throughout the process, providing a reliable positioning reference for each stage of construction, greatly improving positioning accuracy and construction efficiency, reducing rework, ensuring construction quality, and powerfully promoting the progress and development of interior decoration and renovation engineering construction technology.

[0023] The hardware preparation in S1 includes the following hardware: Colored fishing line 1: Select high-toughness, high-identity colored fishing line (such as red or yellow), with a diameter of 0.5-1mm. The color of the fishing line makes it easy for construction workers to quickly identify in complex environments. Its high toughness can prevent breakage due to construction collisions and pulling, ensuring the stability of the positioning mark. Fixing device 2: Small expansion bolts, strong double-sided tape, or U-shaped nails are used as fishing line fixing parts. Expansion bolts are suitable for hard walls such as concrete and brick walls. The fishing line is firmly fixed by drilling holes and installing bolts. Strong double-sided tape is suitable for flat decorative walls (such as plasterboard and wooden walls). It is easy to operate and will not damage the wall surface. U-shaped nails are used for temporary fixing or auxiliary fixing, quickly fixing the fishing line to the preset points on the wall. Height positioning tools: High-precision laser levels, measuring tapes, and other tools are used. The laser level can project a horizontal laser line to help construction workers quickly determine the position of the wall at the same height as the finished ceiling. The measuring tape is used to assist in measuring and calibrating the height of the fishing line, ensuring that the accuracy error is controlled within ±2mm.

[0024] The connection relationships of the above hardware are as follows: Colored fishing line 1 and fixing device 2: According to the design requirements, mark the fixing points of the fishing line on the wall, and use expansion bolts, double-sided tape or U-shaped nails to fix one end of the fishing line to the wall, and extend the other end to the other end of the wall of the corresponding positioning area. By adjusting the tension of the fishing line, ensure that the fishing line is horizontal, straight and without slack. Height positioning tools and colored fishing line 1: Before construction, use a laser level to project a horizontal laser line on the wall that is at the same height as the finished ceiling surface. Using this as a reference, use a tape measure to measure and mark the fixing points of the fishing line to ensure that the fixing height of the fishing line coincides with the laser line, so as to achieve accurate positioning of the fishing line height.

[0025] Construction preparation in S1 includes the following steps: Based on the design drawings, determine the projection positions of equipment such as ceiling sprinklers and air vents on the wall. Using a laser level, a horizontal laser line is projected onto the wall at the same height as the finished ceiling surface. This serves as the height reference for fixing the fishing line. With the finished ceiling surface as the reference, the horizontal and vertical coordinates of the equipment installation are precisely locked by the cross-shaped intersection of the fishing line. Compared with the limitations of traditional chalk lines, which can only determine the horizontal projection or vertical point, this method can achieve precise three-dimensional spatial positioning, ensuring that the equipment installation meets the design requirements.

[0026] The installation of the colored fishing line 1 in S2 includes the following steps: At the wall position corresponding to the equipment positioning point, fix the colored fishing line 1 with expansion bolts, double-sided tape or U-shaped nails to form a horizontal positioning line; If it is necessary to determine the intersection positioning point, repeat the above operation in the vertical direction within the same horizontal plane so that the two fishing lines are in a cross shape in space. This eliminates the disadvantages of ground and floor lines being easily damaged or obstructed. Fix the colored fishing line 1 to the wall to effectively avoid interference from cross operations. The positioning mark is clearly visible throughout the construction process, avoiding repeated construction due to damaged or obstructed marks and ensuring the continuity of construction.

[0027] The equipment positioning and installation in S3 includes the following steps: Using the cross intersection of the colored fishing line as a reference, the corresponding vertical position is used to determine the installation point of the ceiling equipment, simplifying the complicated chalk line operation process. There is no need to frequently climb the floor or repeatedly repair the ground markings. The wall operation space is open and the construction is convenient, which effectively reduces construction time, improves construction efficiency, and speeds up the project progress. Construction workers install equipment based on the intersection of the colored fishing line 1, eliminating the need for ground or floor markings. This allows for precise control of the equipment's installation height and horizontal position, reducing material waste and labor costs caused by rework and improving the first-time pass rate. Stable and reliable positioning marks also reduce construction management and coordination costs, leading to a comprehensive improvement in the overall project benefits.

[0028] The installation and maintenance of colored fishing line 1 in S4 includes the following steps: During construction, since the colored fishing line 1 is fixed high on the wall, it is not easily affected by ground construction activities. If the fishing line becomes loose or shifts, it can be readjusted and fixed through the fixing device 2 to ensure accurate positioning throughout the entire construction process.

[0029] Source protection in S5 includes the following steps: Optimize fishing line selection and configuration: Thicken the fishing line specifications. Depending on the complexity of the construction environment, high-toughness colored fishing line 1 with a diameter of 1-1.2mm can be selected. The thickened fishing line has significantly improved resistance to breakage and tensile strength, which can effectively resist the influence of external forces such as accidental collisions and material friction during construction, and reduce the risk of positioning failure caused by physical damage. At the same time, the high-identifiability color characteristics of the fishing line (such as red and yellow) are maintained to ensure that the thickening does not affect the visual recognition of the construction personnel. Strengthen the stability of the fixing device 2: Select high-strength and compatible fixing parts for different wall bases. For example, use high-hardness small expansion bolts for hard walls such as concrete and brick walls to ensure anchoring depth and firmness; for decorative walls, prioritize high-adhesion and aging-resistant strong double-sided adhesive to avoid the fishing line shifting due to loose fixing parts. Optimize fishing line tension control: Use an adjustable fixing structure (such as an expansion bolt with a locking nut) to precisely control the fishing line tension, avoiding problems such as tangling when too loose or breaking when too tight, and ensuring that the fishing line always remains straight and stable.

[0030] The process protection in S5 includes the following steps: Clear signage and dynamic maintenance: Add visual warning signs and install colored plastic sheet signs. Hang colored plastic sheets at intervals of 50-80cm on the fishing line at the cross-shaped positioning line and key extension sections. The plastic sheets should be in the same color family as the fishing line but in a brighter color (e.g., use bright red plastic sheets when the fishing line is red). The size should be controlled at about 3×5cm. Use a snap-on fixing method (to avoid puncturing the fishing line and causing damage). This signage can quickly remind construction workers of various trades to pay attention and avoid the line in complex construction environments, reducing the risk of accidental contact or pulling. Add warning signs to the area: Post warning signs such as "Protect the positioning line" and "Do not pull" on the walls and ground of the fishing line positioning area to clearly define the construction restricted area. Especially during periods of frequent cross-operation, arrange dedicated personnel to guide the work on-site to avoid damage to the positioning line during the handling of large equipment and materials. Regular inspection frequency: Conduct a comprehensive inspection once before construction, once after lunch break, and once before the end of construction each day, focusing on checking the tension of the fishing line, the firmness of the fasteners, and the integrity of the plastic markings. Address any problems immediately. Quick repair process: If the fishing line becomes loose, tighten it again in time using the adjustable fastener. If the fishing line is partially worn but not broken, add temporary fixing points on both sides of the worn area and replace the section of fishing line. If the fastener is loose, reinforce it or change the fixing method according to the wall material to ensure that the positioning accuracy is not affected.

[0031] S5's process protection is integrated throughout the entire construction process, ensuring full-process protection and guaranteeing positioning accuracy.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
