Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically relating to a safety fixing device for insulation boards and a construction method therein. Background Technology

[0002] Currently, high-rise building exterior wall insulation primarily uses flame-retardant molded polystyrene foam boards (EPS) or extruded polystyrene boards (XPS) as composite materials. Previously, these were connected to the exterior walls using adhesives and insulation nails. However, this method is limited by unevenness in some areas of the exterior wall, the conditions for working at heights with the insulation boards, and the skill level of the workers involved in pasting and installing them. Consequently, construction quality cannot be effectively controlled, leading to frequent problems with insulation layer detachment. Subsequent removal and maintenance of the insulation boards also present significant risks due to the adhesive and nail-fixing methods, and some nails may remain, requiring secondary cleaning. To address these issues, a safe and quick method for installing and removing insulation boards is urgently needed. Summary of the Invention

[0003] To address the problems existing in the prior art, a safety fixing device and construction method for insulation boards are provided.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] This technical solution proposes a safety fixing device for insulation boards, including a five-point fixing assembly. The five-point positioning assembly includes fixing plates and steel strips. The number of steel strips is at least four, and the number of fixing plates is five. Four steel strips are fixed around the perimeter of one of the fixing plates, forming an X-shaped structure. A fixing plate is fixed at each of the four corners of the X-shaped structure. A pre-drilled hole is provided at the center of the fixing plate. At least one steel nail is distributed around the pre-drilled hole, and the steel nail is fixedly connected to one side of the fixing plate.

[0006] Preferably, the steel strip is made of 4cm*1mm flat steel.

[0008] Preferably, each fixing point is provided with four steel nails, and the steel nails are evenly distributed along the circumference.

[0009] Preferably, it also includes a rotating channel mechanism, the rotating channel mechanism including a channel body, a cavity opened at the bottom of the channel body, a T-bolt connected in the cavity, and a locking nut threadedly connected to the T-bolt; one end of the T-bolt can freely pass through the reserved hole; a threaded rod is rotatably connected to the top surface of the channel body.

[0012] S2: Several anchor points are formed on the wall surface that can be fixed to the five-point fixing components;

[0013] S3: Connect the insulation board with the five-point fixing components to the corresponding anchor points on the wall;

[0014] S4: The gap between the insulation board and the wall shall be filled and compacted with foamed concrete.

[0015] This invention also proposes a construction method for a safety fixing device for insulation boards. When the wall is a concrete wall, the steps are as follows:

[0016] S11: The insulation board is placed on the operating platform, and steel nails are hammered into the insulation board to complete the installation of the five-point fixing components and the insulation board.

[0017] S12: Determine the position of the water-stop tie rod eye of the concrete wall formwork by the position of the reserved hole of the five-point fixing component, and open the hole on the formwork;

[0018] S13: Install three-section water-stop tie rods at the template holes. The three-section water-stop tie rod consists of an inner rod connected to two symmetrical outer rods. The inner rod and the outer rods are connected as one unit by a joint nut. After pouring concrete, remove the outer rods of the three-section water-stop tie rods, embed the inner rods in the wall, and use the joint nut as an anchor point for the installation of the insulation board.

[0019] S13: Attach the insulation board with the five-point fixing components to the wall surface and align the pre-drilled holes on the fixing plates with the connector nuts; then use the additionally configured fastening bolts to pass through the pre-drilled holes and thread them onto the connector nuts to complete the fixed installation of the insulation board to the wall.

[0020] S14: The gap between the insulation board and the concrete wall shall be backfilled and compacted with foamed concrete.

[0021] This invention also proposes a construction method for a safety fixing device for insulation boards. When the wall is a brick wall, the steps are as follows:

[0022] S21: The insulation board is placed on the operating platform, and steel nails are hammered into the insulation board to complete the installation of the five-point fixing components and the insulation board.

[0023] S22: Based on the position of the reserved hole in the five-point fixing component, during the masonry process, according to the determined point, a sleeve with internal thread is pre-embedded;

[0024] S23: Attach the insulation board with the five-point fixing components to the surface of the brick wall and align the pre-drilled holes on the fixing plates with the sleeves; then use additional fastening bolts to pass through the pre-drilled holes and connect them to the sleeve threads to complete the fixed installation of the insulation board to the wall;

[0025] S24: The gap between the insulation board and the concrete wall shall be backfilled and compacted with foamed concrete.

[0026] This invention also proposes a construction method for a safety fixing device for insulation boards, which includes the following steps when the wall is a concrete wall:

[0027] S31: The insulation board is placed on the operating platform, and steel nails are hammered into the insulation board to complete the installation of the five-point fixing components and the insulation board.

[0028] S32: Determine the position of the water-stop tie rod eye of the concrete wall formwork by the position of the reserved hole of the five-point fixing component, and open the hole on the formwork;

[0029] S33: Install three-section water-stop tie rods at the template holes. The three-section water-stop tie rod consists of an inner rod connected to two symmetrical outer rods. The inner rod and the outer rods are connected as one unit by a joint nut. After pouring concrete, remove the outer rods of the three-section water-stop tie rods, embed the inner rods in the wall, and use the joint nut as an anchor point for the installation of the insulation board.

[0030] S34: Install the rotary channel mechanism: Connect the threaded rod to the connector nut to install the rotary channel mechanism;

[0031] S35: Insulation board installation: The T-bolt is passed through one of the reserved holes of the fixing piece and the locking nut is tightened to complete the fixing; the position of the T-bolts on the other rotating channels is adjusted to align with the corresponding reserved holes and then passed through and fixed by the corresponding locking nuts.

[0032] S36: Use the above method to complete the installation of the entire wall insulation board;

[0033] S37: The gap between the insulation board and the concrete wall shall be backfilled and compacted with foamed concrete.

[0034] Compared with the prior art, the present invention has the following advantages:

[0035] 1. The present invention uses a five-point fixing component, which can form a steel strip protective frame on the outside of the insulation board, effectively fixing the insulation board and preventing it from being damaged or falling off. The quality after installation is easy to guarantee. The five-point fixing component is equipped with steel nails, which can be hammered in to form a convenient and quick integral with the insulation board. The installation is simple and efficient.

[0036] 2. The insulation board with five fixing components is bolted to the wall. Compared with the traditional adhesive or insulation nail fixing method, this method makes the insulation board more stable after installation and less likely to fall off. When it needs to be removed, the insulation board can be quickly removed by simply turning the bolted parts, which is less dangerous. Moreover, no insulation nails will remain after removal, and no secondary cleaning is required.

[0037] 3. There are two methods for constructing wall anchor points. When the wall is a concrete wall, the anchor points can be formed by removing the three-section water-stop screws. This process is simpler and can effectively improve construction efficiency and save construction steps. When the wall is a brick wall, the sleeves can be pre-embedded according to the design points during the bricklaying process, which can effectively construct the anchor points and also enable the rapid installation and removal of the insulation board.

[0038] 4. Considering that some anchor hole positions may be offset due to errors, the present invention also provides a rotating channel mechanism, which allows the threaded rod and the channel body to rotate relative to each other, thereby facilitating the adjustment of the T-bolt position and making subsequent alignment and installation easier.

[0050] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0051] Example 1

[0052] like Figure 1-6 As shown in the figure, this embodiment proposes a safety fixing device for insulation boards, including a five-point fixing assembly. The five-point positioning assembly includes fixing plates 2 and steel strips 1. The number of steel strips 1 is at least four, and the number of fixing plates 2 is five. Four steel strips 1 are fixed around the perimeter of one of the fixing plates 2, forming an X-shaped structure. A fixing plate 2 is fixed at each of the four corners of the X-shaped structure. A reserved hole 4 is opened at the center of the fixing plate 2 to form a five-point positioning point. At least one steel nail 6 is distributed around the reserved hole 4. The steel nail 6 is fixedly connected to one side of the fixing plate 2 and is used to insert into the insulation board 5 so that the five-point fixing assembly can be effectively fixed to the insulation board 5.

[0053] In this embodiment, two auxiliary support plates 3 are also provided on the left and right sides of the X-shaped structure, forming two diagonally triangular structures. The auxiliary support plates 3 and the steel strip 1 can be made of the same material.

[0054] In this embodiment, the steel strip 1 is made of 4cm*1mm flat steel.

[0055] In this embodiment, the fixing plate 2 is made of a steel plate with a thickness of 1mm and a diameter of 10cm.

[0056] In this embodiment, each fixing point is provided with four steel nails 6, and the steel nails 6 are evenly distributed along the circumference, resulting in better fixing force.

[0057] The present invention employs a five-point fixing component, which can form a steel strip 1 protective frame on the outside of the insulation board 5, effectively fixing the insulation board 5 and preventing the insulation board 5 from being damaged or falling off. The quality after installation is easy to guarantee. The five-point fixing component is equipped with steel nails 6, which can be hammered to easily and quickly form an integral part with the insulation board 5, making the installation simple and efficient.

[0058] This invention also proposes a construction method for a safety fixing device for insulation boards, using the aforementioned five-point fixing components, including the following steps:

[0059] S1: Assemble the five-point fixing components with the insulation board 5;

[0060] S2: Several anchor points are formed on the wall surface that can be fixed to the five-point fixing components;

[0061] S3: Connect the insulation board 5 with the five-point fixing components to the corresponding anchor point on the wall;

[0062] S4: The gap between the insulation board 5 and the wall shall be filled and compacted with foamed concrete.

[0063] In the above method, the wall has two forms: one is a concrete wall 8, and the other is a brick wall. They have different construction methods and different anchor point construction methods, which are explained in detail below:

[0064] Type 1: Concrete wall 8:

[0065] This invention proposes a construction method for a safety fixing device for insulation boards. When the wall is a concrete wall 8, the steps are as follows:

[0066] S11: The insulation board 5 is placed on the operating platform, and the steel nails 6 are hammered into the insulation board 5 to complete the installation of the five-point fixing components and the insulation board 5.

[0067] S12: Determine the position of the water-stop bolt hole of the concrete wall formwork by using the position of the reserved hole 4 of the five-point fixing component, and make the hole on the formwork;

[0068] S13: Install a three-section water-stop tie rod at the template hole. The three-section water-stop tie rod consists of an inner rod connected to two symmetrical outer rods. The inner rod and the outer rods are connected as one unit by the joint nut 9. After pouring concrete, remove the outer rod of the three-section water-stop tie rod, embed the inner rod in the wall, and use the joint nut 9 as the anchor point for the installation of the insulation board 5.

[0069] S13: Attach the insulation board 5 with the five-point fixing assembly to the wall surface and align the reserved hole 4 on the fixing plate 2 with the joint nut 9; then use the additionally configured fastening bolt to pass through the reserved hole 4 and thread it to the joint nut 9 to complete the fixed installation of the insulation board 5 to the wall.

[0070] S14: The gap between the insulation board 5 and the concrete wall 8 shall be backfilled and compacted with foamed concrete.

[0071] In this method, it should be noted that the three-section water-stop screw is a conventional structure and a commonly used product in this field. After removing the two outer rods of the three-section water-stop screw, the joint nut 9 is left inside the concrete wall as a connection point, and no additional construction is required.

[0072] The second type is brick wall:

[0073] This invention also proposes a construction method for a safety fixing device for insulation boards. When the wall is a brick wall 7, the steps are as follows:

[0074] S21: The insulation board 5 is placed on the operating platform, and the steel nails 6 are hammered into the insulation board 5 to complete the installation of the five-point fixing components and the insulation board 5.

[0075] S22: Based on the position of the reserved hole 4 in the five-point fixing assembly, during the masonry process, according to the determined points, a sleeve 71 with internal threads is pre-embedded.

[0076] S23: Attach the insulation board 5 with the five-point fixing components to the surface of the brick wall 7 and align the reserved hole 4 on the fixing plate 2 with the sleeve 71; then use the additionally configured fastening bolts to pass through the reserved hole 4 and thread them to the sleeve 71 to complete the fixed installation of the insulation board 5 and the wall.

[0077] S24: The gap between the insulation board 5 and the concrete wall 8 shall be backfilled and compacted with foamed concrete.

[0078] As can be seen, the insulation board 5 with five fixing components is bolted to the wall. Compared with the traditional adhesive or insulation nail fixing method, this method makes the insulation board 5 more stable after installation and less likely to fall off. When it needs to be removed, the insulation board 5 can be quickly disassembled by simply turning the bolted parts, which is less dangerous. Moreover, no insulation nails will remain after removal, and no secondary cleaning is required.

[0079] There are two methods for constructing wall anchor points. When the wall is a concrete wall 8, the anchor points can be formed by removing the three-section water-stop screws. This process is simpler and can effectively improve construction efficiency and save construction steps. When the wall is a brick wall, the sleeves 71 are pre-embedded according to the design points during the bricklaying process, which can effectively construct anchor points and also enable the rapid installation and removal of the insulation board 5.

[0080] Example 2

[0081] like Figure 7-8As shown, based on Embodiment 1, the present invention further includes a rotating channel mechanism, which includes a channel body 10, which is a "C"-shaped steel structure. A cavity 13 is formed at the bottom of the channel body 10, and a T-bolt 11 is connected to the cavity 13. A locking nut 12 is threaded onto the T-bolt 11. One end of the T-bolt 11 can freely pass through a pre-drilled hole 4. A threaded rod 14 is rotatably connected to the top surface of the channel body 10. The rotatable connection between the threaded rod 14 and the channel body 10 can be achieved using conventional methods, as long as they can rotate relative to each other. The threaded rod 14 is positioned off-center from the center of the channel body 10, allowing for a larger adjustment range. The channel body 10 is approximately 10 cm long. The threaded rod 14 is used to connect to a joint nut 9 on a concrete wall 8 or to a sleeve 71 on a brick wall. The T-bolt 11 is used to connect to a fixing plate 2 and is fixed by the locking nut 12.

[0082] Taking concrete wall 8 as an example, the construction scheme using a rotating channel mechanism includes the following steps:

[0083] S31: The insulation board 5 is placed on the operating platform, and the steel nails 6 are hammered into the insulation board 5 to complete the installation of the five-point fixing components and the insulation board 5.

[0084] S32: Determine the position of the water-stop bolt hole of the concrete wall formwork by using the position of the reserved hole 4 of the five-point fixing component, and make the hole on the formwork;

[0085] S33: Install a three-section water-stop tie rod at the template hole. The three-section water-stop tie rod consists of an inner rod connected to two symmetrical outer rods. The inner rod and the outer rods are connected as one unit by the joint nut 9. After pouring concrete, remove the outer rod of the three-section water-stop tie rod, embed the inner rod in the wall, and use the joint nut 9 as the anchor point for installing the insulation board 5.

[0086] S34: Install the rotary channel mechanism: Thread the threaded rod 14 to the connector nut 9 to install the rotary channel mechanism;

[0087] S35: Installation of insulation board 5: The reserved hole 4 of one of the fixing pieces 2 is passed through by one of the T-bolts 11 and the locking nut 12 is tightened to complete the fixing; the position of the T-bolts 11 on the other rotating channels is adjusted to align with the corresponding other reserved holes 4 and then passed through and fixed by the corresponding locking nuts 12.

[0088] S36: Using the above method, complete the installation of the entire wall insulation board 5;

[0089] S37: The gap between the insulation board 5 and the concrete wall 8 shall be backfilled and compacted with foamed concrete.

[0090] The rotating channel mechanism is designed based on actual conditions. Considering that some anchor hole positions may be offset due to errors, the present invention also provides a rotating channel mechanism. The threaded rod 14 and the channel body 10 can rotate relative to each other, which facilitates the adjustment of the position of the T-bolt 11, thereby facilitating subsequent alignment and installation.

[0091] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
