Abstract

This utility model belongs to the technical field of composite insulation board installation structure, and specifically relates to a fixing device for steam-pressurized concrete composite insulation boards. An upper positioning clip is set on the upper end of the pressure plate and connected to the upper part of the left and right mesh panels. A lower positioning clip is set on the lower end of the insulation material and connected to the lower part of the left and right mesh panels. The lower end of a steel rod passes through the upper positioning clip, the pressure plate, and the insulation material in sequence and connects to the lower positioning clip. The upper end of the hollow tube abuts against the frame, and the lower end of the hollow tube abuts against the upper positioning clip. During pouring, the upper and lower positioning clips on the steel rod position the insulation material in the middle and press it down with the transverse pressure plate. Furthermore, the hollow tube rests against the frame, positioning the insulation material in the center of the left and right mesh panels, ensuring consistent thickness of the left and right panels. In addition, the tension of the connectors on the mesh panels prevents the mesh panels from expanding outwards during pouring, preventing stress caused by later mesh panel deformation that could lead to cracking of the overall composite insulation board.

Description

Technical Field

[0001] This utility model belongs to the technical field of composite insulation board installation structure, and specifically relates to a steam-pressurized concrete composite insulation board fixing device. Background Technology

[0002] Autoclaved aerated concrete (AAC) is a porous concrete structure made primarily from fly ash, lime, cement, gypsum, and slag, with the addition of appropriate amounts of foaming agents, regulators, and bubble stabilizers. The process involves batching, mixing, pouring, static curing, cutting, and high-pressure autoclaving. Existing concrete walls are typically fitted with composite insulation boards to improve the thermal insulation of the concrete structure.

[0003] However, in the existing composite insulation board fixing fixture, the pressure plate and some connectors need to be placed between the two mesh panels for welding. After the insulation material is placed in the middle of the two mesh panels, multiple connectors are inserted through the insulation material and welded to the two mesh panels. The steel rod passes through the pressure plate to hang the whole thing on the frame.

[0004] Secondly, during pouring, too many connectors passing through the insulation material can prevent the concrete from completely filling, resulting in voids. The buoyancy of the insulation material also prevents it from being centered, causing uneven thickness between the left and right panels. Furthermore, the need for manual insertion and welding of numerous connectors is inefficient and generates pollution. Therefore, it is necessary to design a steam-pressurized concrete composite insulation board fixing device to solve these problems. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a steam-pressurized concrete composite insulation board fixing device to solve the issues raised in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steam-pressurized concrete composite insulation board fixing device, applied to a composite insulation board, wherein the composite insulation board includes insulation material and mesh, and two meshes are provided, the two meshes being respectively disposed on the left and right sides of the insulation material; the steam-pressurized concrete composite insulation board fixing device includes:

[0007] A sheet is horizontally positioned at the upper end of the insulation material;

[0008] The upper positioning card is disposed on the upper end of the pressing plate, and the left and right ends of the upper positioning card are detachably connected to the upper part of the left and right mesh sheets respectively.

[0009] The lower positioning card is disposed at the lower end of the insulation material, and the left and right ends of the lower positioning card are detachably connected to the lower part of the left and right mesh panels respectively.

[0010] A steel rod, which is set vertically, has its upper end connected to the work frame, and its lower end passing through the upper positioning clip, the pressure plate, and the insulation material in sequence, and is connected to the lower positioning clip.

[0011] A hollow tube is sleeved on the outside of the steel rod, with its upper end abutting against the work frame and its lower end abutting against the upper positioning clip.

[0012] Furthermore, the upper positioning card has upper positioning card slots at both its left and right ends, and the lower positioning card has lower positioning card slots at both its left and right ends. The upper parts of the left and right mesh panels are respectively inserted into the upper positioning card slots, and the lower parts of the left and right mesh panels are respectively inserted into the lower positioning card slots.

[0013] Furthermore, the lower end of the steel rod is provided with a triangular structure, and the lower end of the middle part of the lower positioning card is provided with a limiting slot. The limiting slot is provided with a through hole in the middle, and the triangular structure is used to pass through the through hole and rotate to the lower end of the bottom surface of the limiting slot.

[0014] Furthermore, the steam-pressurized concrete composite insulation board fixing device also includes:

[0015] The connector is arranged longitudinally, with its middle section passing through the insulation material, and its left and right ends are detachably connected to the left and right mesh panels respectively.

[0016] Furthermore, the left and right ends of the connector are twisted to form collars, and the two collars are respectively sleeved with the left and right mesh pieces, with the opening of the collars curving upwards.

[0017] Furthermore, the steam-pressurized concrete composite insulation board fixing device also includes:

[0018] A spring, which is sleeved on the upper end of the steel rod;

[0019] A washer, which is fitted onto the steel rod and located at the lower end of the spring;

[0020] A pin is located at the lower end of the washer and passes through the steel rod. The work frame has two layers. The upper layer of the work frame has an upper hole, and the lower layer of the work frame has a lower hole. The pin passes through the upper hole and abuts against the lower end of the upper layer of the work frame. The washer abuts against the lower end of the upper layer of the work frame. The lower end of the steel rod passes through the upper hole and the lower hole in sequence and is inserted into the hollow tube.

[0021] Furthermore, the tablet press is configured as either groove-shaped or flat.

[0022] The technical effects and advantages of this utility model are as follows:

[0023] 1. During pouring, the upper and lower positioning clips on the steel rods keep the insulation material in the middle position and press it down with the horizontal pressure plate; secondly, the hollow tube is supported by the scaffold, which can prevent the insulation material from shifting due to buoyancy during the overall pouring, so that the insulation material is in the center position of the left and right mesh sheets, ensuring that the thickness of the left and right sheets is consistent.

[0024] 2. By inserting the upper part of the left and right mesh panels into the upper positioning slot and the lower part of the left and right mesh panels into the lower positioning slot, the installation of the upper positioning card, lower positioning card and mesh panels is easier compared to the welding connection method.

[0025] 3. The bottom surface of the limiting slot can be used to abut against the upper surface of the triangular structure to limit the lower end of the steel rod, thereby facilitating the connection between the steel rod and the lower positioning card.

[0026] 4. The collar can be fitted onto the left and right mesh panels, facilitating the connection of the connector to the left and right mesh panels. This eliminates the need for welding connections, improving efficiency and reducing pollution from welding.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] The positive X-axis points forward, and the negative X-axis points backward; the positive Y-axis points to the left, and the positive Y-axis points to the right; the positive Z-axis points to the top, and the negative Z-axis points to the bottom.

[0038] like Figures 1 to 6 As shown in the figure, a steam-pressurized concrete composite insulation board fixing device according to an embodiment of the present invention is applied to a composite insulation board. The composite insulation board includes insulation material 1 and mesh 2. Two mesh 2 are provided, and the two mesh 2 are respectively arranged on the left and right sides of the insulation material 1. The steam-pressurized concrete composite insulation board fixing device includes a pressure plate 3, an upper positioning clip 4, a lower positioning clip 5, a steel rod 6, and a hollow tube 7. The pressure plate 3 is arranged horizontally on the upper end of the insulation material 1. The upper positioning clip 4 is arranged on the upper end of the pressure plate 3, and the left and right ends of the upper positioning clip 4 are detachably connected to the upper part of the left and right mesh 2 respectively. The lower positioning clip 5 is arranged on the lower end of the insulation material 1, and the left and right ends of the lower positioning clip 5 are detachably connected to the lower part of the left and right mesh 2 respectively. The steel rod 6 is arranged vertically. The upper end of the steel rod 6 is connected to the frame 18, and the lower end of the steel rod 6 passes through the upper positioning clip 4, the pressure plate 3, and the insulation material 1 in sequence and is connected to the lower positioning clip 5. The hollow tube 7 is sleeved on the outside of the steel rod 6, the upper end of the hollow tube 7 abuts against the work frame 18, and the lower end of the hollow tube 7 abuts against the upper positioning clip 4.

[0039] Specifically, after passing through the hollow tube 7, the upper positioning card 4, and the horizontally installed pressure plate 3, the steel rod 6 is vertically inserted into the insulation material 1 all the way to the lower positioning card 5 at the bottom. The left and right ends of the upper positioning card 4 are connected to the upper part of the left and right mesh 2, and the left and right ends of the lower positioning card 5 are connected to the lower part of the left and right mesh 2, so that the steel rod 6, the hollow tube 7, the upper positioning card 4, the pressure plate 3, the lower positioning card 5, the insulation material 1, and the left and right mesh 2 form a whole.

[0040] Therefore, during pouring, the upper positioning clip 4 and lower positioning clip 5 on the steel rod 6 position the insulation material 1 in the middle and hold it down with the transverse pressure plate 3. Secondly, the hollow tube 7 rests on the frame 18, which can prevent the insulation material 1 from shifting due to buoyancy during overall pouring, thus keeping the insulation material 1 in the center of the left and right mesh sheets 2 and ensuring that the thickness of the left and right sheets is consistent. In addition, setting the pressure plate 3 horizontally helps to increase the contact surface between the pressure plate 3 and the insulation material 1, preventing the buoyancy during pouring from tearing the insulation material 1 due to the small contact surface. At the same time, the pressure plate 3 and the upper positioning clip 4 form a cross-shaped stable state, which helps to control the distance between the mesh sheets 2 on both sides and the insulation material 1.

[0041] In this embodiment, after the concrete has solidified, the steel rod 6 is removed to complete the action. Next, the insulation material 1, after being poured, is divided into left and right sheets. Furthermore, the pressing sheet 3 can be either grooved or flat. The flat type is a long strip structure, while the grooved type is a long strip structure with both sides bent into grooves.

[0042] like Figure 2 and Figure 3 As shown, optionally, the upper positioning card 4 is provided with upper positioning card slots 8 at both the left and right ends, and the lower positioning card 5 is provided with lower positioning card slots 9 at both the left and right ends. The upper parts of the left and right mesh pieces 2 are respectively inserted into the upper positioning card slots 8, and the lower parts of the left and right mesh pieces 2 are respectively inserted into the lower positioning card slots 9.

[0043] Specifically, by inserting the upper parts of the left and right mesh panels 2 into the upper positioning slot 8 and the lower parts of the left and right mesh panels 2 into the lower positioning slot 9, compared to the welding connection method, it is easier to install the upper positioning card 4, lower positioning card 5 and mesh panel 2. In case of installation errors, it is also easy to disassemble and reinstall the upper positioning card 4, lower positioning card 5 and mesh panel 2.

[0044] like Figure 3 and Figure 4As shown, optionally, the lower end of the steel rod 6 is provided with a triangular structure 10, and the lower end of the lower positioning card 5 is provided with a limiting slot 11. The limiting slot 11 is provided with a through hole 12 in the middle. The triangular structure 10 is used to pass through the through hole 12 and rotate to the lower end of the bottom surface of the limiting slot 11.

[0045] Specifically, the lower end of the limiting slot 11 is open, and the bottom surface of the limiting slot 11 is located above the opening. When connecting the steel rod 6 to the lower positioning clip 5, the triangular structure 10 at the lower end of the steel rod 6 is inserted into the limiting slot 11, so that the triangular structure 10 passes through the through hole 12, and then the steel rod 6 is rotated until the triangular structure 10 is located below the bottom surface of the limiting slot 11. Thus, the bottom surface of the limiting slot 11 and the upper surface of the triangular structure 10 can be used to limit the lower end of the steel rod 6, thereby facilitating the connection between the steel rod 6 and the lower positioning clip 5.

[0046] In this embodiment, the triangular structure 10 can be rotated 90 degrees to the lower end of the bottom surface of the limiting slot 11.

[0047] like Figure 1 and Figure 5 As shown, optionally, the steam-pressurized concrete composite insulation board fixing device further includes a connector 13, which is arranged longitudinally and there are multiple connectors 13. The middle of the multiple connectors 13 passes through the insulation material 1, and the left and right ends of the multiple connectors 13 are detachably connected to the left and right mesh panels 2 respectively.

[0048] Specifically, the upper positioning slots 8 at both ends of the upper positioning card 4 and the lower positioning slots 9 at both ends of the lower positioning card 5 respectively lock the upper and lower parts of the left and right mesh panels 2. Secondly, multiple longitudinally inserted connectors 13 connect the left and right mesh panels 2 simultaneously, keeping the distance between them fixed. Thus, the tension of the connectors 13 on the mesh panels 2 prevents them from expanding outwards during pouring, preventing stress caused by deformation of the mesh panels 2 later on, which could lead to cracking of the overall composite insulation board.

[0049] Furthermore, connector 13 can be adopted Figure 2 or Figure 3 The structure shown is used to connect the left and right mesh panels 2;

[0050] In existing technologies, multiple connectors 13 not only fix the left and right mesh panels 2 but also control the buoyancy of the insulation material 1. In this embodiment, the upper positioning clip 4 and lower positioning clip 5 on the steel rod 6 are used to position the insulation material 1 in the middle and press it down with the transverse pressure plate 3, thus offsetting the buoyancy of the insulation material 1. The number of connectors 13 can be reduced accordingly. Therefore, the number of connectors 13 can be reduced during pouring, avoiding the formation of voids due to too many connectors 13 passing through the insulation material 1 that cannot be completely filled by concrete.

[0051] like Figure 5 As shown, optionally, the left and right ends of the connector 13 are twisted to form collars 14, and the two collars 14 are respectively sleeved with the left and right mesh pieces 2, with the opening of the collar 14 curving upward.

[0052] Specifically, by twisting the left and right ends of the connector 13 to form collars 14, the collars 14 can be fitted onto the left and right mesh panels 2, facilitating the connection between the connector 13 and the left and right mesh panels 2. Therefore, the insertion of the connector 13 eliminates the need for welding, improving efficiency and reducing pollution caused by welding. Secondly, the upward curve of the collar 14 opening facilitates installation.

[0053] like Figure 1 , Figure 4 as well as Figure 6 As shown, optionally, the steam-pressurized concrete composite insulation board fixing device further includes a spring 15, a washer 16, and a pin 17. The spring 15 is sleeved on the steel rod 6. The washer 16 is sleeved on the steel rod 6 and located at the lower end of the spring 15. The pin 17 is located at the lower end of the washer 16 and passes through the steel rod 6. The frame 18 has two layers. The upper layer of the frame 18 has an upper hole 19, and the lower layer of the frame 18 has a lower hole 20. The pin 17 is used to pass through the upper hole 19 and is engaged with the lower end of the upper layer of the frame 18. The washer 16 abuts against the upper end of the upper layer of the frame 18. The lower end of the steel rod 6 passes through the upper hole 19 and the lower hole 20 in sequence.

[0054] Specifically, such as Figure 4 As shown, a spring 15 is installed on the steel rod 6. After passing through the upper hole 19 and lower hole 20 of the frame 18, the steel rod 6 passes through the hollow tube 7, the upper positioning clip 4, the pressure plate 3, and the insulation material 1 in sequence, and connects with the lower positioning clip 5. After the pin 17 passes through the upper hole 19, the steel rod 6 is rotated so that the pin 17 is locked at the lower end of the upper hole 19 of the frame 18, and the triangular structure 10 is locked in the lower positioning clip 5. The gasket 16 presses against the upper end of the upper hole 19 to compress the spring 15. Under the action of the spring 15, the triangular structure 10 is locked into the lower positioning clip 5 and then springs back to tighten the lower positioning clip 5. At the same time, the hollow tube 7 at the position of the lower hole 20 is tightened, so that the hollow tube 7 is pressed against the frame 18. In this way, the entire steam-pressurized concrete composite insulation board fixing device can be kept in a fixed state, which is convenient for pouring. Secondly, the buoyancy generated by the insulation material 1 during the overall casting is negligible due to the action of the spring 15 on the frame 18 and the steel rod 6 by the hollow tube 7, which makes it easy to ensure that the insulation material 1 is located in the center of the left and right mesh sheets 2 and to ensure that the thickness of the left and right sheets is consistent.

[0055] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
