Description

Technical Field

[0001] The invention relates to a tool for installing a pipe thermal insulation material, in particular to a tool for installing a pipe thermal insulation material inside a casing that is used for penetrating a wall or floor slab, and a method for using the tool. Background Art

[0002] During construction, pipe casings are typically installed where pipes pass through walls or floors to prevent direct contact between the main structure of the wall or floor and the pipes, thereby protecting the pipes. When the pipes passing through walls or floors are hot or cold water pipes, insulation material is required between the pipes and the casing to prevent heat loss.

[0003] However, in practice, insulation is typically performed after all pipes are installed. The gap between wall and floor casings and the pipes is small, making it difficult to insert insulation. Currently, there are two main methods for installing insulation between pipes and casings: one is to replace the original insulation with a foaming agent; the other is to force insulation into the gap between the casing and the pipe. However, both methods have drawbacks. Method 1 essentially replaces the insulation material, resulting in performance that does not meet design and specification requirements; and it also fails to ensure the continuity, density, and integrity of the insulation. Method 2 is inconvenient to install, not only easily damaging the insulation material but also failing to ensure the continuity and density of the insulation filling. Due to the installation difficulties, disconnection of the insulation at the casing is common. All of these construction methods can create localized cold bridges, increasing heat loss and wasting energy. For chilled water pipes, this is even more likely to result in the insulation system losing its proper functionality due to damage to the moisture barrier.

[0004] The above problems have always been insurmountable obstacles for construction workers and construction managers due to the difficulty of construction and the large number of casing parts. Summary of the Invention

[0005] One of the purposes of the present invention is to provide a pipeline insulation material installation tool to solve the problem that the insulation material between the pipeline and the sleeve is inconvenient to install.

[0006] A second object of the present invention is to provide a method for using a tool for installing a pipe insulation material, so as to provide a method for using a tool for installing a pipe insulation material.

[0007] One of the objects of the present invention is achieved as follows: a pipeline insulation material installation tool, comprising a flexibly bendable steel plate, on which are provided a plurality of parallel ribs, the ribs being spaced apart along the curling direction of the steel plate, and each of the ribs being hingedly provided with a pressure rod at the same side end, the length of the pressure rod being equal to the length of the rib; the hinged end of the rib protruding from the edge of the steel plate, so that each of the pressure rods can be rotated around the hinge axis toward the rib rod; a push-pull handle is provided on the edge of the steel plate on the side close to the hinge axis of the pressure rod.

[0008] The compression rod is an L-shaped rod with a horizontal portion provided at a hinged end, and the length of the horizontal portion is smaller than the gap between the wall-penetrating steel pipe and the sleeve.

[0009] A U-shaped groove is provided on the hinged end of the rib rod, and the U-shaped groove is arranged along the rotation direction of the pressure rod; the free end of the horizontal part of the hinged end of the pressure rod is provided with a protrusion embedded in the U-shaped groove, and the hinge shaft passes through the groove wall of the U-shaped groove and the protrusion to realize the hinge connection between the rib rod and the pressure rod.

[0010] The rib rods are arranged on the outer surface of the steel plate, and the pressure rods are opened and closed relative to the rib rods around the hinge axis on the outer side of the steel plate.

[0011] Preferably, the steel plate is a square plate, and the ribs are parallel to a pair of sides of the square plate.

[0012] The thermal insulation material installation tool of the present invention is used to install thermal insulation material between a pipe and a sleeve. The tool includes a steel plate, a plurality of ribs are provided on the steel plate, and a pressure rod is hinged on the rib. When using this tool, first wrap the steel plate on the pipe, then wrap the thermal insulation material on the outside of the steel plate, and then use the pressure rod to compress the thermal insulation material to make it smaller, so that the tool and the thermal insulation material can be stuffed into the gap between the pipe and the sleeve together, and finally withdraw the tool from the gap, and the thermal insulation material is left at the installation position, thus completing the installation of the thermal insulation material. This tool has low production cost and is easy to operate and use. It can support the thermal insulation material during installation to prevent the thermal insulation material from being damaged, and can meet the quality requirements of pipeline insulation construction. In addition, the use of this installation tool can reduce the difficulty of installing the thermal insulation material between the pipe and the sleeve, and improve construction efficiency.

[0021] h. Release the pressure rod and push the handle of the installation tool to pull the installation tool out of the installation position in the opposite direction, so that the insulation material and the installation tool are gradually separated and finally remain between the wall-penetrating pipe and the casing, thus completing the installation of the insulation material.

[0022] The dimension of the heat-insulating material along the wall-penetrating pipe direction is smaller than the length of the compression rod and the rib rod.

[0029] Example 1: A pipeline insulation material installation tool.

[0030] like Figure 1As shown, the present invention includes a steel plate 3, which can be flexibly bent. A plurality of parallel ribs 4 are provided on the steel plate 3, and the ribs 4 are arranged parallel to the curling direction of the steel plate 3. A pressure rod 1 is hinged at the same side end of each rib 4, and the length of the pressure rod 1 is equal to the length of the rib 4. The hinged end of the rib 4 extends beyond the edge of the steel plate 3, so that the hinged joint between the rib 4 and the pressure rod 1 will not interfere with the steel plate 3, so that the pressure rod 1 can smoothly turn around the hinge axis 5 in the direction of the rib 4 to open, close and separate. The present invention also provides a push-pull handle 2 on the side edge of the hinge axis 5 of the steel plate close to the pressure rod 1. The setting of the push-pull handle 2 facilitates the removal of the device from between the wall-penetrating pipe 7 and the sleeve.

[0031] like Figure 2 As shown in Figure (a), the hinged end of the pressure rod 1 of the present invention is provided with a horizontal portion, so that the pressure rod is L-shaped as a whole. In order to facilitate the insertion of the tool into the gap between the sleeve and the wall pipe 7, the length of the horizontal portion of the pressure rod 1 of the present invention is less than the gap between the wall pipe 7 and the sleeve. The free end of the horizontal portion of the hinged end of the pressure rod 1 is provided with a protrusion, such as Figure 2 As shown in Figure (b).

[0032] like Figure 3 As shown in Figures (a) and (b), the hinged end of the rib bar 4 is provided with a U-shaped groove, extending along the direction of the compression rod's rotation. The protrusion at the free end of the horizontal portion of the hinged end of the compression rod 1 is nestled within the U-shaped groove. This structural arrangement serves as a position limiter for both sides of the rotating compression rod 1, thereby protecting the hinged end. A hinge shaft 5 passes through the walls of the U-shaped groove on the rib bar 4 and the protrusion on the compression rod 1, achieving the hinged connection between the rib bar 4 and the compression rod 1.

[0033] In the present invention, the ribs 4 are disposed on the outer surface of the steel plate 3, and the compression rod 1 is arranged on the outer surface of the steel plate 3 to open and close the ribs around the hinge axis 5. The ribs 4 disposed on the outer surface of the steel plate 3 prevent contact between the ribs 4 and the wall-penetrating pipe 7 during use, thereby preventing the wall-penetrating pipe 7 from being scratched by the ribs 4.

[0034] like Figure 1 As shown, the steel plate 3 in the present invention is a square plate, and the plurality of ribs 4 are parallel to one pair of sides of the steel plate 3. In this embodiment, six ribs 4 and six pressure rods 1 are provided.

[0035] Example 2: A method for using a pipeline insulation material installation tool.

[0036] This method comprises the following steps:

[0037] S1. First, prepare the installation tool of the pipeline insulation material introduced in Example 1. The size and dimensions of the installation tool can be determined according to the size of the pipeline.

[0038] S2, install the wall-penetrating pipe 7. The wall-penetrating pipe 7 is passed through the sleeve on the reserved hole on the wall 8 or the floor, and then the wall-penetrating pipe 7 is installed and fixed.

[0039] S3. Cut the insulation material 6 according to the outer diameter of the wall-penetrating pipe 7 and the length of the sleeve, so that the axial dimension of the insulation material 6 along the wall-penetrating pipe 7 is smaller than the length of the pressure rod 1 and the rib rod 4. The insulation material used in this embodiment is the commonly used insulation cotton wrapped around the HVAC pipe.

[0040] S4. Wrap the cut insulation material 6 on the steel plate 3 on the wall-penetrating pipe 7, and then rotate the pressure rod 1 toward the rib rod 4 so that the pressure rod 1 squeezes the insulation material 6 at the same time, so that the insulation material 6 is compressed and becomes smaller.

[0041] S5. Then, the thermal insulation material is pushed along the axial direction of the wall-penetrating pipe 7 together with the installation tool to the installation position, that is, pushed to the gap between the sleeve and the wall-penetrating pipe 7.

[0042] S6. Release the pressure rod 1 and pull the push-pull handle 2 of the installation tool to pull the installation tool out of the installation position in the opposite direction. Note that you should pull it out slowly and observe the thermal insulation material 6. The thermal insulation material 6 should be gradually separated from the installation tool to avoid the thermal insulation material 6 being withdrawn together with the installation tool. Finally, the thermal insulation material 6 is left between the wall-penetrating pipe 7 and the sleeve, thereby completing the installation of the thermal insulation material 6 between the wall-penetrating pipe 7 and the sleeve in the reserved hole on the wall 8 or floor. The specific structure after the installation is completed is as follows: Figure 4 shown.

[0043] In order to facilitate the installation tool to smoothly enter the gap between the sleeve and the wall-penetrating pipe 7, the outer side of the free end of the pressure rod 1 in this embodiment is provided with an inclined surface inclined toward the free end.
