Description

Technical Field

[0001] This invention relates to the building energy conservation and environmental protection industry, specifically to a method for using a tool to press straight grooves into the thermal conductive layer of an insulation board. Background Technology

[0002] Precast grooved insulation board is a general term for underfloor heating modules.

[0003] Precast grooved insulation panels are factory-made boards with fixed length, width, spacing, and groove dimensions. They serve both load-bearing and thermal insulation purposes and are primarily used in underfloor heating systems in buildings. After the precast grooved insulation panels are assembled on-site, heating pipes or cables are laid within the grooves.

[0004] Concrete insulation board is a lightweight porous concrete board made by adding foaming agent to a slurry made of cement-based cementitious materials, aggregates, admixtures, additives and water, mixing and stirring, pouring and molding, and curing by natural or steam curing. It is also called foamed concrete insulation board.

[0005] Concrete insulation boards possess excellent properties such as light weight, good thermal insulation, sound absorption, and fire resistance. They are suitable for exterior wall insulation and fire-resistant barriers, and are also used in underfloor heating insulation projects. The advantages of concrete insulation boards include energy saving, environmental protection, low carbon footprint, waste utilization, non-toxicity, and the ability to utilize industrial waste, thus promoting sustainable development. Concrete insulation boards are one of the leading products in building insulation, and their application in underfloor heating installations is becoming increasingly widespread.

[0006] To better achieve energy conservation and emission reduction, a metal heat-conducting layer with grooves of the same size as the outer diameter of the heating pipe is laid on the prefabricated grooved insulation board used in the underfloor heating installation project. The purpose is to quickly conduct the heat energy below the heating element upward to improve heating efficiency.

[0007] Existing technologies typically use aluminum foil with a thickness of less than 0.1mm, which has poor thermal conductivity. Furthermore, adhesive-backed aluminum foil can release harmful gases when heated. Only by applying an unadhesive-backed aluminum sheet with a thickness of more than 0.2mm to the precast curved groove concrete insulation board can good thermal conductivity and energy-saving effects be achieved.

[0008] Currently, there are machines that use mechanical stamping to process aluminum sheets with a thickness of about 0.2mm into straight grooves. However, the stamped aluminum sheets are very large. They not only require anti-crush cardboard packaging, resulting in high transportation costs, but they are also prone to deformation after being removed. The deformed aluminum sheets do not adhere well to the insulation board, requiring on-site reshaping by construction personnel.

[0009] The lack of specialized tools for reshaping deformed grooved aluminum sheets is very time-consuming and affects construction efficiency.

[0010] Currently, there are no tools or methods for directly pressing aluminum sheets laid on straight groove insulation boards. Summary of the Invention

[0011] This invention discloses a method for using a tool to press straight grooves into the thermal conductive layer of an insulation board. The purpose of this invention is to provide a method for pressing aluminum sheets covering prefabricated straight groove insulation boards to form grooves on a construction site, so as to improve construction efficiency.

[0012] A method for using a tool for pressing straight grooves into the thermal conductive layer of an insulation board. The tool includes a fixed handle, a movable handle, a first pressure plate, a second pressure plate, a groove pressing head, and a sleeve. A first connecting rod and a limiting crossbar are located below the fixed handle. The groove pressing head is located below the first connecting rod, and the straight groove pressing head is rotatably connected to the first pressure plate via a first hinge. A second hinge of the groove pressing head is rotatably connected to the second pressure plate via a connecting head. The first pressure plate is rotatably connected to the lower end of a first cross rod via a lower hinge. The first cross rod is rotatably connected to the second connecting rod. The second pressure plate is rotatably connected to the lower end of the second cross rod via a lower hinge. The second cross rod is rotatably connected to the second connecting rod via an upper hinge. The second pressure plate is rotatably connected to the lower end of the second cross rod via a lower hinge. The second cross rod is rotatably connected to the second connecting rod via an upper hinge. A movable handle is located at the upper end of the second connecting rod. The method of using this tool includes the following steps:

[0013] Step 1, Preparation:

[0014] 1) Confirm whether the grooves of the precast straight groove insulation board are compatible with 16mm diameter water pipes or 20mm diameter water pipes;

[0015] 2) Confirm that the aluminum sheet is suitable for making a heat-conducting layer, with a thickness between 0.15mm and 0.3mm;

[0016] 3) Confirm that the width of the aluminum sheet is equal to or greater than the length of the groove in the prefabricated straight groove insulation board;

[0017] 4) Confirm that the length of the aluminum sheet is greater than the length of the grooved end of the precast straight groove insulation board, and is at least the width of eight straight grooves.

[0018] 5) Ensure the workers wear clean, soft-soled rubber shoes to prevent damage to the aluminum sheet;

[0019] 6) Prepare three pressing tools, two of which are used to remove the second pressing plate and its connected accessories;

[0020] 7) Prepare at least two thin plates with a thickness of less than 5mm, a width of less than 120mm, and a length of more than 600mm.

[0021] Step 2, Match the grooved extrusion head:

[0022] If the groove of the insulation board is to be installed with a 16mm diameter water pipe, the sleeve should be removed from the groove extrusion head; if the groove of the insulation board is to be installed with a 20mm diameter water pipe, the sleeve should be fitted under the groove extrusion head.

[0023] Step 3: Place aluminum sheets on the insulation board:

[0024] 1) Align the longer side of the aluminum sheet with both ends of the groove on the prefabricated straight groove insulation board;

[0025] 2) Place one side of the aluminum sheet that is the same width as the precast straight groove insulation board parallel to the groove on the precast straight groove insulation board, and make this side of the aluminum sheet exceed the width of three straight grooves of the precast straight groove insulation board.

[0026] 3) Make the other side of the aluminum sheet, which is the same width as the precast straight insulation board, exceed the width of five straight grooves of the precast straight insulation board;

[0027] Step 4, Extruding the groove: (Taking the extruded groove as an example for installing a 16mm diameter water pipe)

[0028] 1) Hold the fixed handle with one hand and pull the movable handle upwards with the other hand to flip the first and second pressure plates upwards;

[0029] 2) Place the groove extrusion head on the second groove from the side of the aluminum sheet that exceeds the width of the three straight grooves of the insulation board, and make the long side of the groove extrusion head parallel to the long side of the groove of the insulation board under the aluminum sheet, and place the groove extrusion head within the two long side lines of the groove of the insulation board.

[0030] 3) Apply downward pressure to the fixed handle, so that the groove extrusion head presses against the aluminum sheet under the groove extrusion head, and so that the aluminum sheet covering the area below the groove extrusion head is completely inserted into the U-shaped groove;

[0031] 4) With one hand, continue to press down on the fixed handle, and with the other hand, apply pressure to the movable handle to make the first and second pressure plates flip down until the first and second pressure plates press the aluminum sheets on both sides of the groove extrusion head onto the prefabricated insulation board.

[0032] 5) Facing the direction where the groove will be pressed into the aluminum sheet, place your feet on the ends of the first and second pressure plates respectively, and relinquish control of the first pressing tool with your hands;

[0033] 6) Take the second pressing tool, and the second pressing worker should remove the second pressure plate;

[0034] 7) Place the first pressure plate of the second pressing tool on the side furthest from the operator;

[0035] 8) Hold the fixed handle of the second pressing tool, and pull the movable handle upward with the other hand to flip the first pressing plate upward;

[0036] 9) Place the groove extrusion head of the second pressing tool on the groove closest to the worker's toes, and make the long side of the groove extrusion head parallel to the long side of the groove of the insulation board under the aluminum sheet, and place the groove extrusion head within the two long side lines of the insulation board groove.

[0037] 10) Apply downward pressure to the fixed handle of the second pressing tool so that the groove extrusion head presses the aluminum sheet below the groove extrusion head completely into the U-shaped groove;

[0038] 11) With one hand, continue to press down on the fixed handle of the second pressing tool, and with the other hand, press down on the movable handle of the second pressing tool to make the first pressing plate flip down until the first pressing plate presses the aluminum sheet below onto the prefabricated insulation board.

[0039] To press the third and fourth grooves onto the aluminum sheet, repeat steps four through four.

[0040] Step 5, remove the grooved extrusion head:

[0041] 1) With one hand, continue to press down on the fixed handle, and with the other hand, pull up the movable handle to flip the pressure plate upwards and make it perpendicular to the length of the groove. Then, rock it back and forth with the bottom of the groove extrusion head as the center to loosen the gap between the groove extrusion head and the extruded U-shaped groove.

[0042] 2) Continue to shake and pull the fixed handle until the groove extrusion head is completely separated from the extruded U-shaped groove;

[0043] 3) If the groove extrusion head is difficult to separate, a thin plate with a thickness of less than 5mm, a width of less than 120mm, and a length of more than 600mm should be placed under the pressure plate so that the thin plate is pressed on the aluminum sheet. One long side of the thin plate should be close to the groove extrusion head. The operator should step on the thin plate while pulling the fixed handle until the groove extrusion head separates from the extruded U-shaped groove.

[0044] In preferred embodiment one, a preferred option of the basic embodiment, first magnetic blocks are provided below both ends of the grooved extrusion head; the sleeve is provided with a U-shaped groove, and second magnetic blocks are provided at both ends of the U-shaped groove; the U-shaped groove on the sleeve matches the size, shape, and length of the grooved extrusion head, and when the U-shaped groove is fitted under the grooved extrusion head and aligned at both ends, the first and second magnetic blocks will attract each other. This design facilitates the quick installation of the U-shaped groove and utilizes the mutual attraction of the magnetic blocks to prevent the U-shaped groove from falling off from under the grooved extrusion head.

[0045] Preferred Option 2, as a preferred option of Preferred Option 1, wherein the grooved extrusion head is made of metal; the first pressure plate, the first cross rod, the second pressure plate and the second cross rod, the first connecting rod and the limiting cross rod are made of metal sheet to prevent the tool components from deforming when pressure is applied.

[0046] Preferred option three, as a preferred option two, is that the sleeve is made of elastic engineering plastic, making it easier and more convenient for the user to remove the sleeve.

[0047] Preferred Option 4, as a preferred embodiment of Preferred Option 3, has a grooved extrusion head with a length of 600mm, a width of 16mm, and a height of 16mm; the sleeve has a length of 600mm, a width of 20mm, and a height of 20mm. The U-shaped groove of the sleeve perfectly matches the grooved extrusion head. Using the grooved extrusion head allows for the pressing of grooves for installing 16mm diameter water heating pipes, while using the sleeve allows for the pressing of grooves for installing 20mm diameter water heating pipes. This technical solution is suitable for most indoor water-based underfloor heating systems currently on the market. Attached Figure Description
