Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to an auxiliary installation device for exterior wall EPS boards and a method for fixing exterior wall EPS boards. Background Technology

[0002] In modern architecture, EPS (expanded polystyrene) boards are increasingly used in the construction of building facades due to their lightweight, good thermal insulation, and convenient construction. However, there are relatively many types of EPS boards depending on the design requirements. Some EPS boards, due to their relatively large height and width, need to be pasted separately during construction, with gaps filled using plaster mortar and alkaline fiber mesh. Furthermore, the fixing of EPS boards relies on manual string lines, adhesives, and insulation nails. While this method is simple, it also has its drawbacks:

[0003] 1. Manually pulling the alignment line introduces significant errors and cannot achieve in-situ centering of the EPS board. Furthermore, the alignment line only considers verticality and does not take into account the flatness of the EPS board, resulting in large deviations in verticality and flatness after installation.

[0004] 2. Adhesives and insulation nails can only fix individual EPS boards, without considering the overall stability of the EPS boards. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, an auxiliary installation device and a fixing method for external wall EPS boards are provided to solve the problem that the existing method of manually laying EPS boards with a string line cannot achieve in-situ alignment of the EPS boards.

[0006] To achieve the above objectives, an auxiliary installation device for exterior wall EPS panels is provided, comprising:

[0007] A base for centrally positioned between two adjacent EPS boards on an exterior wall in a horizontal direction includes a wall-mounted panel, at least four cantilever assemblies with adjustable length, and a base plate. The wall-mounted panel is detachably attached to the exterior wall, the base plate is disposed opposite to the wall-mounted panel, and the at least four cantilever assemblies are connected between the base plate and the wall-mounted panel.

[0008] Two horizontally arranged gauges are respectively installed on the outside of the substrate. The gauges are arranged along the surface of the substrate, and a reference space is formed between the gauges and the outer wall for embedding the EPS board of the outer wall.

[0009] A distance measuring instrument is used to obtain the distance between the measuring rod and the outer wall, and the distance measuring instrument is installed on each of the two measuring rods;

[0010] A level is mounted on the base plate;

[0011] The locking structure includes a locking nail and a locking cable. The nail shank of the locking nail penetrates the exterior wall EPS board and is anchored inside the exterior wall. The nail head of the locking nail presses against the side of the exterior wall EPS board away from the exterior wall. The locking cable is connected to the nail heads of the locking nails on multiple exterior wall EPS boards and presses against the outer side of the multiple exterior wall EPS boards.

[0012] Furthermore, the cantilever assembly includes:

[0013] A threaded sleeve is connected to the inner side of the substrate;

[0014] A movable screw, one end of which is screwed into the threaded sleeve;

[0015] A helical spring, one end of which is fixedly connected to the wall plate, and the other end of which is rotatably connected to the other end of the movable screw.

[0016] Furthermore, the at least four cantilever components are arranged in a matrix.

[0017] Furthermore, the wall panel is detachably attached to the exterior wall using suction cups.

[0018] Furthermore, the securing nail is an insulating nail.

[0019] Furthermore, the locking cable is made of carbon fiber filament.

[0020] Furthermore, the level is a bubble level.

[0021] Furthermore, one end of each of the two gauges is coaxially connected together.

[0022] This invention provides a method for fixing external wall EPS boards using an auxiliary installation device, comprising the following steps:

[0023] Mark the vertical centering baseline on the exterior wall;

[0024] Multiple base wall panels are respectively installed on the outer wall, and the multiple wall panels are spaced apart along the length direction of the centering reference line, with the central axis of the wall panel coinciding with the centering reference line;

[0025] The distance measuring instruments on the two measuring rods of the base respectively obtain the real-time distance between the measuring rod and the outer wall;

[0026] Based on the level and the real-time distance, adjust the length of the at least four cantilever components so that the base plate is vertically set, the distances from the two leveling rods to the outer wall are equal, and the two leveling rods form a reference space with the outer wall respectively;

[0027] The exterior wall EPS board is laid on the exterior wall, and the exterior wall EPS board is embedded in the reference space;

[0028] The distance from the external wall EPS board to the centering baseline is measured by measuring with a leveling rod, so that the external wall EPS boards on both sides of the centering baseline are aligned in situ.

[0029] After the exterior wall EPS board is aligned in situ, the nail bar of the locking structure is inserted through the exterior wall EPS board and anchored inside the exterior wall, and the nail head of the locking nail presses against the side of the exterior wall EPS board away from the exterior wall.

[0030] The locking structure is connected to the nail heads of the locking nails on multiple exterior wall EPS panels and pressed against the outside of the multiple exterior wall EPS panels.

[0031] The beneficial effects of this invention are as follows: the auxiliary installation device for exterior wall EPS panels achieves in-situ alignment of two exterior wall EPS panels in the horizontal direction through the leveling rod on the base. By adjusting the cantilever assembly, a reference space is formed between the two leveling rods and the exterior wall, thereby ensuring the flatness of the exterior wall EPS panels on both sides of the alignment reference line after the exterior wall EPS panels are laid. Finally, the locking screws on the exterior wall EPS panels on both sides of the alignment reference line are connected together by locking cables, and the exterior wall EPS panels are pressed against the exterior wall by the locking cables, thereby improving the overall stability and positioning accuracy of the exterior wall EPS panels.

[0036] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] Reference Figures 1 to 3 As shown, the present invention provides an auxiliary installation device for external wall EPS boards, including: a base 1, a leveling rod 2, a distance measuring instrument 3, a level 4, and a locking structure 5.

[0039] The base is centrally positioned between two adjacent exterior wall EPS panels 6 in the horizontal direction. Specifically, the base 1 includes a wall-mounted panel 11, at least four cantilever assemblies 12, and a base plate 13.

[0040] The wall panel 11 is detachably attached to the exterior wall. The base plate 13 is disposed opposite to the wall panel 11. At least four cantilever assemblies 12 are connected between the base plate 13 and the wall panel 11.

[0041] The length of the cantilever assembly 12 is adjustable. At least four cantilever assemblies 12 are arranged in a matrix.

[0042] In this embodiment, four cantilever assemblies are used. The wall panel and the substrate are the same size and shape, both being rectangular. The four cantilever assemblies are respectively located at the four corners of the substrate. When assisting in the installation of the exterior wall EPS panels, the length of the four cantilever assemblies is adjusted to make the substrate vertical or vertically positioned.

[0043] In this embodiment, two leveling rods are used. The leveling rods are telescopic. Each leveling rod is positioned horizontally. The two leveling rods 2 are coaxially arranged. The two leveling rods 2 are respectively installed on the outer side of the base plate 13, with the leveling rods 2 positioned along the surface of the base plate 13. A reference space is formed between the leveling rods 2 and the outer wall for embedding the outer wall EPS board 6.

[0044] When assisting in the installation of exterior wall EPS panels, the end of the leveling rod is pressed against the outer side of the exterior wall EPS panel, so that the exterior wall EPS panel is tightly attached to the exterior wall.

[0045] The distance measuring instrument 3 is used to obtain the distance between the leveling rod 2 and the outer wall. Two leveling rods 2 are each equipped with a distance measuring instrument 3. Through the distance measuring instruments on the two leveling rods, the distance between the two leveling rods and the outer wall can be displayed in real time, thereby showing the flatness of the EPS panels on the outer wall on both sides of the base in the horizontal direction.

[0046] The level 4 is mounted on the substrate 13. The level is used to display the verticality of the substrate.

[0047] The locking structure 5 includes a locking nail 51 and a locking cable 52. The nail shank of the locking nail 51 penetrates through the exterior wall EPS board 6 and is anchored inside the exterior wall. The nail head of the locking nail 51 presses against the side of the exterior wall EPS board 6 away from the exterior wall. The locking cable 52 connects to the nail heads of the locking nails 51 on multiple exterior wall EPS boards 6 and presses against the outer side of the multiple exterior wall EPS boards 6.

[0048] In a preferred embodiment, the cantilever assembly 12 includes a threaded sleeve 121, a movable screw 122, and a helical spring 123.

[0049] A threaded sleeve 121 is connected to the inner side of the base plate 13. One end of a movable screw 122 is screwed into the threaded sleeve 121. One end of a helical spring 123 is fixedly connected to the wall plate 11. The other end of the helical spring 123 is rotatably connected to the other end of the movable screw 122.

[0050] In this embodiment, the threaded sleeve, movable screw, and helical spring are coaxially arranged. When adjusting the posture of the substrate, the bending deformation performance of the helical spring is utilized, and the posture adjustment of the substrate is achieved through the coordinated operation of the four cantilever components.

[0051] As a preferred embodiment, the wall panel 11 is detachably attached to the exterior wall by means of suction cup 111.

[0052] In this embodiment, the locking nail 51 is an insulating nail. The locking cable 52 is a carbon fiber filament. The level 4 is a bubble level. One end of the two leveling rods 2 is coaxially connected together.

[0053] This invention provides a method for fixing external wall EPS boards using an auxiliary installation device, comprising the following steps:

[0054] S1. Mark the vertical centering baseline on the exterior wall.

[0055] S2. Install the wall-mounted panels 11 of the multiple bases 1 onto the exterior wall. The multiple wall-mounted panels 11 are spaced apart along the length of the centering baseline, and the central axis of the wall-mounted panels 11 coincides with the centering baseline.

[0056] S3 and the distance measuring instruments 3 on the two measuring rods 2 of the base 1 respectively obtain the real-time distance between the measuring rod 2 and the outer wall.

[0057] S4. Based on the level instrument 4 and the real-time distance, adjust the length of at least four cantilever components 12 so that the base plate 13 is set vertically, the distances from the two level gauges 2 to the outer wall are equal, and the two level gauges 2 form a reference space with the outer wall respectively.

[0058] S5. Lay the exterior wall EPS board 6 on the exterior wall, and embed the exterior wall EPS board 6 in the reference space;

[0059] S6. Observe the distance from the external wall EPS board 6 to the centering baseline by measuring with a leveling rod 2, so that the external wall EPS boards 6 on the opposite sides of the centering baseline are aligned in place.

[0060] S7. After aligning the exterior wall EPS board 6 in its original position, insert the nail rod of the locking structure 5's locking nail 51 through the exterior wall EPS board 6 and anchor it inside the exterior wall. The nail head of the locking nail 51 presses against the side of the exterior wall EPS board 6 away from the exterior wall.

[0061] S8. Connect the locking cable 52 of the locking structure 5 to the nail head of the locking nail 51 on the multiple exterior wall EPS panels 6 and press it against the outside of the multiple exterior wall EPS panels 6.

[0062] A locking cable is installed at the gap between the EPS panels on opposite sides of the centering baseline. The locking cable first connects the top caps of the two horizontal retaining nails, and then diagonally upwards connects to the top caps of the retaining nails of the EPS panel on the upper layer above the gap, as shown below. Figure 1 The interlocking cables shown are Z-shaped. For multi-layered exterior EPS panels, the interlocking cables are multiple continuously arranged Z-shapes.

[0063] After installing the locking cables and retracting the tower rod, remove the base from the exterior wall.

[0064] In some embodiments, the gauge is rotatably mounted on the outside of the base plate via a slewing bearing. Furthermore, a locking element is mounted on the base plate. When the gauge is in a horizontal direction, the locking element locks the gauge. After the gauge is retracted, the locking element is released, allowing the gauge to be rotated to facilitate the removal and storage of the base.

[0065] The auxiliary installation device for exterior wall EPS panels of the present invention achieves in-situ alignment of two exterior wall EPS panels in the horizontal direction through the leveling rod on the base. By adjusting the cantilever assembly, a reference space is formed between the two leveling rods and the exterior wall, thereby ensuring the flatness of the exterior wall EPS panels on both sides of the alignment reference line after the exterior wall EPS panels are laid. Finally, the locking screws on the exterior wall EPS panels on both sides of the alignment reference line are connected together by locking cables, and the exterior wall EPS panels are pressed against the exterior wall by the locking cables, thereby improving the overall stability and positioning accuracy of the exterior wall EPS panels.

[0066] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
