Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a construction method for an adjustable ceiling sprinkler system. Background Technology

[0002] Currently, the following problems exist in the construction of suspended ceiling fire sprinkler systems: First, most sprinkler terminals are rigid pipes, and the pre-embedding and positioning of sprinkler heads are crude, making it impossible to achieve precise positioning and adjustment, and they are prone to misalignment with the ceiling panels, light fixtures, and sealing. Second, there are no unified leveling control measures for the installation of ceiling hangers and keels, resulting in insufficient overall flatness and stability, and easy deformation and cracking. Third, the construction process is generally such that the ceiling is sealed first and then the sprinkler heads are adjusted, which makes later rectification difficult and results in a high rework rate.

[0003] Therefore, the construction methods for existing ceiling sprinkler systems need to be improved to avoid reversing the order of procedures. Leveling the keel can enhance the quality of construction. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a construction method for an adjustable ceiling sprinkler system, which can avoid reversing the process. At the same time, the keel in the whole system can be directly snapped on during installation, which can improve the installation speed and adjust the flatness of the keel to improve the project quality.

[0005] The construction method of the adjustable ceiling sprinkler system of the present invention includes the following steps:

[0006] S1: Measure and lay out the lines to determine the installation position of the main keel;

[0007] S2: Install several hanger assemblies at the installation location, and adjust and lock the height of each hanger assembly relative to the installation location according to the construction requirements;

[0008] S3: Install the main keel, which is snapped into the bottom of the corresponding hanger assembly;

[0009] S4: Install the snap-fit ​​connector and snap it onto the bottom of the main keel;

[0010] S5: Install the sprinkler fixed keel and the movable clamp. The two ends of the sprinkler fixed keel are respectively slidably connected to the two adjacent main keels and form an I-shaped structure with the two main keels. Install the movable clamp on the sprinkler fixed keel and the position of the movable clamp relative to the sprinkler fixed keel is adjustable and can be locked.

[0011] S6: Install one end of the sprinkler hose onto the moving clamp;

[0012] S7: Install the secondary keel, snap the secondary keel into the lower part of the clip, then install the ceiling baseboard onto the secondary keel, and then install the ceiling panel onto the ceiling baseboard.

[0013] Further, in step S2, the boom assembly includes a mounting rod and a connector. The mounting position is provided with a threaded hole for mounting the mounting rod. The mounting rod is threaded into the threaded hole and the screw depth of the mounting rod is adjustable and can be locked. The position of the connector relative to the mounting rod is adjustable and can be locked. The main keel is snapped into the connector.

[0014] Furthermore, the boom assembly also includes two adjusting nuts. The mounting rod is provided with a threaded adjusting section, and the two adjusting nuts are disposed on the threaded adjusting section. The connector is sleeved on the threaded adjusting section and can slide along the threaded adjusting section. The connector is clamped by the two adjusting nuts, so that the position of the connector relative to the mounting rod is adjustable and can be locked.

[0015] Furthermore, the connector forms an installation space I for installing the main keel. The installation space I is composed of a horizontal section I, a bending section, a vertical section, a horizontal section II, and a snap-fit ​​section I. The two ends of the horizontal section I extend downwards to form the bending section, one end of the bending section bends downwards to form the vertical section, one end of the vertical section bends inwards to form the horizontal section II, and one end of the horizontal section II extends upwards and inwards to form the snap-fit ​​section I.

[0016] The main keel is a rectangular tubular structure. The two sides of the upper end of the rectangular tubular structure extend downward and outward to form a snap-fit ​​part I, which snaps into the snap-fit ​​section I.

[0017] Furthermore, in step S4, the snap-fit ​​component includes an upper mounting space, which is composed of a horizontal plate, an upper vertical section, an upper horizontal section, and an upper snap-fit ​​section. The left and right sides of the horizontal plate are bent upward to form the upper vertical section, one end of the upper vertical section is bent inward to form the upper horizontal section, and one end of the upper horizontal section is tilted downward and outward to form the upper snap-fit ​​section.

[0018] The two sides of the lower end of the rectangular tubular structure extend upward and outward to form a snap-fit ​​part II, which snaps into the upper snap-fit ​​section.

[0019] Furthermore, the snap-fit ​​component also includes a lower mounting space, which is composed of a lower vertical section and a lower snap-fit ​​section. The lower vertical section is formed by bending downwards on both the front and rear sides of the horizontal plate, and one end of the lower vertical section extends upwards and outwards to form the lower snap-fit ​​section.

[0020] The secondary keel has a U-shaped structure. Both ends of the U-shaped secondary keel bend outward and downward to form a snap-fit ​​part III, which snaps into the lower snap-fit ​​section.

[0021] Furthermore, in step S5, the spray fixing keel includes a fixing section and a snap-fit ​​part IV disposed at both ends of the fixing section. The snap-fit ​​part I and the snap-fit ​​part II form a snap-fit ​​space. The snap-fit ​​part IV is inserted into the snap-fit ​​space and forms a snap-fit ​​with the snap-fit ​​part I and the snap-fit ​​part II. The snap-fit ​​part IV can slide along the snap-fit ​​space.

[0022] Furthermore, in step S5, the movable clamp includes a sliding part, which is a U-shaped structure. The sliding part of the U-shaped structure includes a fixed plate and two sliding plates. One end of each of the two sliding plates is fixedly connected to the two ends of the fixed plate. The sliding plates are provided with sliding holes. The sliding plates pass through the sliding holes into the fixed section. The fixed plate is located on the outside of the fixed section and is fixed by a fastener.

[0023] Furthermore, the movable clamp also includes a clamping part, which includes two clamping arms, each corresponding to one end of the other side of the two sliding plates, for clamping the sprinkler hose and locking it with a locking member.

[0024] The beneficial effects of this invention are as follows: The construction method of the adjustable ceiling sprinkler system of this invention allows for adjustable height of the hanger components relative to their installation positions. This enables the adjustment of the height of each hanger component according to the actual requirements of the construction site, thereby adjusting the flatness of the main keel and improving project quality. Furthermore, the main and secondary keels are installed using a snap-fit ​​method and in reverse, eliminating the need for bolts or other fixing tools, significantly improving construction efficiency. The overall frame has good integrity and facilitates later maintenance, reducing material waste and further lowering project costs. Additionally, the adjustable position of the movable clamps relative to the sprinkler fixing keel facilitates adjustment of the sprinkler head position, effectively solving the problems of traditional sprinkler fixing systems that are unable to fine-tune and prone to deviation from their positions.

[0039] like Figure 1-11 As shown: The construction method of the adjustable ceiling sprinkler system in this embodiment includes the following steps:

[0040] S1: Measure and lay out the lines to determine the installation position of the main keel 4;

[0041] S2: Install several hanger assemblies at the installation location, and adjust and lock the height of each hanger assembly relative to the installation location according to the construction requirements;

[0042] S3: Install the main keel 4, which is snapped into the lower part of the corresponding hanger assembly;

[0043] S4: Install connector 8 and attach connector 8 to the bottom of the main keel 4;

[0044] S5: Install the sprinkler fixing keel 9 and the movable clamp 6. The two ends of the sprinkler fixing keel 9 are respectively slidably clamped to the two adjacent main keels 4, and form an I-shaped structure with the two main keels 4. The movable clamp 6 is installed on the sprinkler fixing keel 9 and the position of the movable clamp 6 relative to the sprinkler fixing keel 9 is adjustable and can be locked.

[0045] S6: Install one end of the sprinkler hose onto the movable clamp 6;

[0046] S7: Install the secondary keel 3, clip the secondary keel 3 to the bottom of the clip 8, then install the ceiling base plate to the secondary keel 3, and then install the ceiling panel 5 to the ceiling base plate.

[0047] like Figure 1 As shown, the hanger assembly is installed at the installation position, and the height of the hanger assembly is adjustable. This allows the height of each hanger assembly to be adjusted according to the actual needs of the construction site, thereby adjusting the flatness of the main keel 4, and thus the flatness of the ceiling panel 5 and the ceiling base plate. This improves the quality of the project. At the same time, the main keel 4, secondary keel 3, and sprinkler fixing keel 9 are all installed using a snap-fit ​​method, eliminating the need for welding, drilling, and a large number of fasteners. On-site personnel can complete the coordinated assembly of the main keel 4, secondary keel 3, and sprinkler fixing keel 9, significantly reducing cross-operation procedures, shortening the construction period, and improving the convenience and standardization of construction.

[0048] The position of the sprinkler fixing keel 9 relative to the main keel 4 is adjustable, and the position of the movable clamp 6 relative to the sprinkler fixing keel 9 is also adjustable. This allows for adjustment of the position of the sprinkler hose, thereby adjusting the position of the sprinkler head. The sprinkler head can be precisely adjusted to the design position, effectively solving the pain points of traditional sprinkler fixing systems that cannot be finely adjusted and are prone to deviation from the position. It takes into account the convenience of installation, structural stability, and maintenance. At the same time, partial disassembly and repair can be carried out during later maintenance without damaging the overall structure, which can reduce maintenance costs.

[0049] In this embodiment, in step S2, the boom assembly includes a mounting rod 1 and a connector 2. The mounting position is provided with a threaded hole for mounting the mounting rod 1. The mounting rod 1 is threaded into the threaded hole and the screw depth of the mounting rod 1 is adjustable and can be locked. The position of the connector 2 relative to the mounting rod 1 is adjustable and can be locked. The main keel 4 is snapped into the connector 2.

[0050] like Figure 1 As shown, the mounting rod 1 has an external thread on its body. The mounting rod 1 is threaded into the mounting position and locked in place by a nut. Therefore, the height of the mounting rod 1 can be adjusted by adjusting the depth of its screw thread. Simultaneously, the position of the connecting piece 2 relative to the mounting rod 1 can also be adjusted, thereby further adjusting the overall height of the suspension rod assembly (relative to the bolt assembly). Figure 1(Up and down direction) to achieve precise adjustment of the flatness of the main keel 4, thereby adjusting the flatness of the ceiling panel 5, which can adapt to the construction needs of various construction sites.

[0051] In this embodiment, the boom assembly further includes two adjusting nuts 10. The mounting rod 1 is provided with a threaded adjusting section, and the two adjusting nuts 10 are disposed on the threaded adjusting section. The connector 2 is sleeved on the threaded adjusting section and can slide along the threaded adjusting section. The connector 2 is clamped by the two adjusting nuts 10, so that the position of the connector 2 relative to the mounting rod 1 is adjustable and can be locked.

[0052] like Figure 2 As shown, the two adjusting nuts 10 clamp the connecting piece 2, thereby allowing it to move along... Figure 2 Adjust the position of the connector 2 relative to the mounting rod 1 in the up and down direction, and further fine-tune the installation flatness of the main keel 4.

[0053] In this embodiment, the connector 2 forms an installation space I for installing the main keel 4. The installation space I is composed of a horizontal section I 201, a bending section 202, a vertical section 203, a horizontal section II 204, and a snap-fit ​​section I 205. The two ends of the horizontal section I 201 extend downwards to form the bending section 202. One end of the bending section 202 bends downwards to form the vertical section 203. One end of the vertical section 203 bends inwards to form the horizontal section II 204. One end of the horizontal section II 204 extends upwards and inwards to form the snap-fit ​​section I 205.

[0054] The main keel 4 is a rectangular tubular structure. The two sides of the upper end of the rectangular tubular structure extend downward and outward to form a snap-fit ​​part I401, which snaps into the snap-fit ​​section I205.

[0055] like Figure 4 As shown, connector 2 forms installation space I for installing the main keel 4, relative to... Figure 2 In the vertical direction, the horizontal section I 201 is provided with a through hole that mates with the mounting rod 1, so that the horizontal section I 201 is clamped between two adjusting nuts 10. The two ends of the horizontal section I 201 are inclined downward to form a bent section 202. One end of the bent section 202 is bent downward to form a vertical section 203. One end of the vertical section 203 is bent inward to form a horizontal section II 204. The horizontal section II 204 extends upward and outward (i.e. away from the vertical section) to form a snap-fit ​​section I 205.

[0056] like Figure 5 The main keel 4 is described as a rectangular tubular structure, relative to... Figure 5In the vertical direction, the upper two sides of the rectangular tubular structure are bent downward and outward to form the snap-fit ​​part I401. Thus, during assembly, since the installation space I is an open structure, the main keel 4 is passed through one end of the installation space I to complete the assembly. When the main keel 4 is installed in the set position, the snap-fit ​​part I401 snaps into the snap-fit ​​section I205. The main keel 4 can be assembled and fixed without the use of bolts or other fasteners, which can reduce costs and improve construction efficiency.

[0057] In this embodiment, in step S4, the snap-fit ​​component 8 includes an upper mounting space, which is composed of a horizontal plate 802, an upper vertical section 804, an upper horizontal section 803, and an upper snap-fit ​​section 801. The left and right sides of the horizontal plate 802 are bent upward to form the upper vertical section 804, one end of the upper vertical section 804 is bent inward to form the upper horizontal section 803, and one end of the upper horizontal section 803 is tilted downward and outward to form the upper snap-fit ​​section 801.

[0058] The two sides of the lower end of the rectangular tubular structure extend upward and outward to form a snap-fit ​​part II 402, which snaps into the upper snap-fit ​​section 801.

[0059] like Figure 7 As shown, relative to Figure 7 In the vertical direction, the opposite sides of the horizontal plate 802 bend upward to form the upper vertical section 804. During assembly, the upper installation space is inserted from one end of the main keel 4, and then moved along the axis of the main keel 4 to the installation position. The upper snap-fit ​​section 801 and the snap-fit ​​part II 402 are snap-fitted together, thus making the installation convenient.

[0060] In this embodiment, the snap-fit ​​component 8 further includes a lower mounting space, which is composed of a lower vertical section 806 and a lower snap-fit ​​section 805. The front and rear sides of the horizontal plate 802 are bent downward to form the lower vertical section 806, and one end of the lower vertical section 806 extends upward and outward to form the lower snap-fit ​​section 805.

[0061] The secondary keel 3 has a U-shaped structure. Both ends of the U-shaped secondary keel 3 are bent outward and bent downward to form a snap-fit ​​part Ⅲ301, which is snapped into the lower snap-fit ​​section 805.

[0062] like Figure 6 As shown, relative to Figure 6 In the vertical direction, the two ends of the U-shaped secondary keel 3 bend outwards and downwards to form the snap-fit ​​part Ⅲ301, as shown below. Figure 7 As shown, the opening directions of the upper and lower installation spaces are different. Therefore, after installation, the plane where the main keel 4 is located is approximately perpendicular to the plane where the secondary keel 3 is located. Figure 7 In the vertical direction, the other two opposite sides of the horizontal plate 802 are bent downward to form a lower vertical section 806. Thus, during installation, one end of the secondary keel 3 is inserted from one end of the lower installation space, and when the secondary keel 3 is placed in the installation position, the lower snap-fit ​​section 805 and the snap-fit ​​part Ⅲ301 form a snap-fit.

[0063] In this embodiment, in step S5, the spray fixing keel 9 includes a fixing section 901 and a snap-fit ​​part IV 902 disposed at both ends of the fixing section 901. The snap-fit ​​part I 401 and the snap-fit ​​part II 402 form a snap-fit ​​space. The snap-fit ​​part IV 902 is inserted into the snap-fit ​​space and forms a snap-fit ​​with the snap-fit ​​part I 401 and the snap-fit ​​part II 402. The snap-fit ​​part IV 902 can slide along the snap-fit ​​space.

[0064] like Figure 8 As shown, the fixed section 901 has a locking part Ⅳ902 at both ends. The fixed section 901 and the locking part Ⅳ902 form an I-shaped structure. The locking part Ⅰ401 and the locking part Ⅱ402 form a locking space with one side wall of the main keel 4. During installation, the locking part Ⅳ902 is placed parallel to the locking space and then rotated 90° so that the locking part Ⅳ902 is perpendicular to the axis of the main keel 4. Thus, the locking part Ⅰ401 and the locking part Ⅱ402 limit the locking part Ⅳ902. In use, the position of the spray fixing keel 9 relative to the main keel 4 can be adjusted according to the needs of use to adjust the position of the spray hose.

[0065] In this embodiment, in step S5, the movable clamp 6 includes a sliding part 602, which is a U-shaped structure. The U-shaped sliding part 602 includes a fixed plate and two sliding plates. One end of each sliding plate is fixedly connected to the two ends of the fixed plate. The sliding plate is provided with a sliding hole. The sliding plate passes through the sliding hole into the fixed section 901. The fixed plate is located on the outside of the fixed section 901 and is fixed by a fastener 603.

[0066] like Figure 9 and Figure 10 As shown, the fixing member 603 is a fixing bolt, and the fixing plate is provided with a threaded hole, so that the fixing member 603 passes through the threaded hole to form a fastening between the fixing plate and the fixing section 901, so that the position of the sliding part 602 relative to the fixing section 901 is adjustable and can be locked.

[0067] In this embodiment, the movable clamp 6 further includes a clamping part, which includes two clamping arms 601. The two clamping arms 601 are respectively disposed at the other end of the two sliding plates to clamp the spray hose and are locked by a locking member 604.

[0068] like Figure 9 As shown, the locking component 604 consists of a locking bolt and a locking nut. The two clamping arms 601 are provided with fixing holes that cooperate with the locking bolt, thereby locking the clamping space formed between the two clamping arms 601, which facilitates locking the water spray hose 7. When in use, the position of the water spray hose 7 can be precisely adjusted, thereby realizing the adjustment of the position of the spray head. Compared with the existing technology, it can reduce the probability of rework.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
