Description

Technical Field

[0001] The invention belongs to the technical field of thermal insulation board fixing structures, and particularly relates to a fixing system for external wall thermal insulation boards of municipal buildings. Background Art

[0002] With the acceleration of the urbanization process and the improvement of people's requirements for living environments, the external wall thermal insulation technology of municipal buildings has been increasingly emphasized. External wall thermal insulation can not only effectively reduce energy consumption, improve the energy efficiency of buildings, but also enhance the thermal insulation and heat insulation performance of buildings, and improve the living comfort. However, there are certain deficiencies in the traditional fixing methods of external wall thermal insulation boards. The existing fixing methods of external wall thermal insulation boards mainly include the bonding fixing method, the mechanical anchoring method, and the bonding and anchoring combination method. The bonding fixing method mainly uses special polymer bonding mortar for bonding, and the applicable scenarios are bases with relatively high flatness, such as concrete and brick walls, and are commonly used for EPS / XPS thermal insulation boards. The mechanical anchoring method is fixed through structures such as plastic expansion anchor bolts and fire-resistant anchor bolts, and is applicable to high-rise buildings, areas with large wind pressures, or applicable scenarios with uneven bases. The bonding and anchoring combination method is to bond first and then anchor, taking into account wind pressure resistance and durability, and is widely used in various thermal insulation systems. Since the pasting method is simple in construction, the durability and bonding strength of the adhesive are often difficult to guarantee, and the thermal insulation board may fall off due to long-term exposure to wind and sun, posing a safety hazard. Therefore, anchoring or the bonding and anchoring combination method is generally adopted in the market. When installing thermal insulation boards by either the anchoring or the bonding and anchoring combination method, although the fixing effect is good, the fixing position cannot be adjusted after the structure is installed. Therefore, a large amount of time needs to be wasted on measurement in the early stage of installation. If an error occurs after installation, the device needs to be disassembled as a whole and fixed again. The device has poor adjustability and low applicability. Summary of the Invention

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 - 9 as shown, the present invention provides the following technical solutions:

[0032] A fixing system for thermal insulation boards on the outer wall of a municipal building includes a main hanging piece 1 fixedly connected horizontally to the outer wall of the building. The main hanging piece 1 includes a supporting part and a plurality of abutting parts slidably connected to the supporting part;

[0033] Moreover, in the present invention, after the support part is fixed, in order to install multiple abutting parts, one side of the support part away from the building exterior wall is open to form a side groove 16. The side groove 16 is distributed along the length direction of the support part, and two guiding grooves 17 are symmetrically recessed inside the side groove 16.

[0034] In addition, in the present invention, regarding the above-mentioned abutting part, the abutting part includes a connecting plate 19. The connecting plate 19 is slidably connected between the two guiding grooves 17. An abutting cavity for abutting the heat-insulating board 3 is formed between the connecting plates 19 on adjacent two support parts. A first limiting rod 110 is screwed onto the connecting plate 19. The free end of the first limiting rod 110 extends into the side groove 16 to abut against the support part. A side plate 111 is fixedly connected to the side of the connecting plate 19 away from the side groove 16, and a first through hole 113 is formed in the side plate 111.

[0035] Through the above technical solution, before installing the heat-insulating board 3, first clean the floating ash and oil stains on the wall surface, repair large-area depressions with polymer cement mortar, locate the installation positions of the main hangers 1 by snapping the grid line, press the support part against the position on the wall where the personnel need to install, and mark the drilling positions. Drill holes at the marked points with an impact drill, and fix the support part to the wall through the drilling and other structures. According to the above steps, fix the support parts in all areas on the wall where the heat-insulating board 3 needs to be installed. After the support parts are fixed, take the required number of connecting plates 19 by the personnel, connect the connecting plates 19 to the side groove 16 on the support part, and install the connecting plates 19 between the two guiding grooves 17. After the connecting plates 19 are placed, pull the connecting plates 19 to make the connecting plates 19 slide along the guiding grooves 17 until the connecting plates 19 move to the positions required by the personnel. Rotate the first limiting rod 110 on the connecting plates 19 to make the first limiting rod 110 move relative to the connecting plates 19 until the free end of the first limiting rod 110 moves into the side groove 16 and the free end of the connecting plates 19 abuts against the support part, thereby fixing the positions of the connecting plates 19. According to the above steps, adjust the positions of the other connecting plates 19 to the positions required by the personnel. After the positions of all the connecting plates 19 are adjusted, place the heat-insulating board 3 to be fixed between the connecting plates 19 on the upper and lower two support parts, and then insert the bolts into the first through holes 113 in the side plates 111 and rotate to make the bolts enter the heat-insulating board 3, thereby fixing the heat-insulating board 3. According to the above steps, complete the installation of the other heat-insulating boards 3.

[0036] Moreover, when the personnel install the heat-insulating board 3 on the building exterior wall, due to different requirements, the thicknesses of the heat-insulating boards 3 are also different. In order to enable the device to be adjusted according to the thickness of the heat-insulating board 3, such as Figures 1 - 5 、 Figure 7 and Figure 8As shown, on the side of the side plate 111 away from the connecting plate 19, a first connecting hole 117 is formed by indentation, and an extension plate 112 is provided on the side of the side plate 111 away from the connecting plate 19. A through second connecting hole 18 is horizontally formed on the extension plate 112. A detachable connecting inner rod 116 is screwed between the second connecting hole 18 and the first connecting hole 117. A through second through hole 115 is vertically formed on the extension plate 112, and the second through hole 115 is between the two second connecting holes 18.

[0037] In this embodiment, when the support part is fixed and the thickness of the insulation board 3 to be installed is relatively large, place the connecting plate 19 in the side groove 16 on the support part, and after engaging the top and bottom of the connecting plate 19 between the two guiding grooves 17, pull the connecting plate 19 to move the connecting plate 19 along the guiding groove 17 until the connecting plate 19 moves to the position required by the personnel. Rotate the first limiting rod 110 on the connecting plate 19 until the free end of the connecting plate 19 moves into the interior of the side groove 16 and makes the free end of the connecting plate 19 contact the support part, thereby fixing the position of the connecting plate 19. According to the above steps, adjust the positions of the other connecting plates 19. After the positions of all the connecting plates 19 are adjusted, take the required number of extension plates 112 according to the thickness of the insulation board 3. Place the extension plates 112 on one side of the side plate 111, and insert the connecting inner rod 116 between the first connecting hole 117 and the second connecting hole 18 on the extension plate 112 and the side plate 111. Rotate the connecting inner rod 116 to connect the extension plate 112 to the side plate 111. According to the above steps, place the other extension plates 112 in sequence and connect them through the connecting inner rod 116. After the length of the extension plate 112 is adjusted, place the insulation board 3 to be fixed between the side plates 111 on the upper and lower support parts, and make the extension plate 112 contact the insulation board 3. Then insert the bolt into the first through hole 113 on the side plate 111 and the second through hole 115 on the extension plate 112 and rotate it to make the bolt enter the insulation board 3, thereby fixing the insulation board 3. According to the above steps, complete the installation of the other insulation boards 3.

[0038] Specifically, in one embodiment, regarding the above support part, as Figures 1 - 6 shown, the support part includes a base frame 11. The side groove 16 is formed on the side of the base frame 11 facing the connecting plate 19, and a plurality of fixed anchor rods 12 are screwed inside the side groove 16, and the plurality of fixed anchor rods 12 are between the two guiding grooves 17.

[0039] In this embodiment, when a person needs to fix the base frame 11, before installing the thermal insulation board 3, the floating ash and oil stains on the wall surface are cleaned, and large-area depressions are repaired with polymer cement mortar. The installation position of the base frame 11 is positioned by snapping the grid line. The base frame 11 is closely attached to the position on the wall where the person needs to install. The punching positions are marked, and holes are drilled at the marked points with an impact drill. Then, the fixing anchor bolts 12 are passed through the base frame 11 and screwed into the drilled holes. By the fixing anchor bolts 12 abutting against the base frame 11, the base frame 11 is fixed.

[0040] After the thermal insulation board 3 is connected between two adjacent base frames 11, if the side of the thermal insulation board 3 is not fixed, the stability of the thermal insulation board 3 is relatively poor. Therefore, in the present invention, a structure for fixing the side of the thermal insulation board 3 is provided, such as Figures 1 - 4 and Figure 9 shown, the top and bottom of the base frame 11 are recessed to form clamping grooves 13, and a secondary hanging member 2 for abutting against the thermal insulation board 3 is slidably connected inside the clamping grooves 13.

[0041] In this embodiment, after the base frame 11 is fixed, the connecting plate 19 is placed in the side groove 16 on the base frame 11. After the top and bottom of the connecting plate 19 are clamped between the two guiding grooves 17, the connecting plate 19 is pulled to move the connecting plate 19 along the guiding groove 17 until the connecting plate 19 moves to the position required by the person. The first limiting rod 110 on the connecting plate 19 is rotated until the free end of the connecting plate 19 moves inside the side groove 16 and the free end of the connecting plate 19 abuts against the base frame 11, thereby fixing the position of the connecting plate 19. According to the above steps, the positions of other connecting plates 19 are adjusted. After the positions of all the connecting plates 19 are adjusted, the thermal insulation board 3 to be fixed is placed between the side plates 111 on the upper and lower base frames 11, and the extension plate 112 abuts against the thermal insulation board 3. Then, bolts are inserted into the first through holes 113 on the side plates 111 and the second through holes 115 on the extension plate 112 and rotated to make the bolts enter the thermal insulation board 3, thereby fixing the thermal insulation board 3. Then, the secondary hanging member 2 is connected to the clamping grooves 13 at the top and bottom of the base frame 11, so that the secondary hanging member 2 is installed at the top and bottom of the base frame 11. According to the above steps, the required number of secondary hanging members 2 are installed on the base frame 11. By two adjacent secondary hanging members 2 abutting against the side of the thermal insulation board 3, the thermal insulation board 3 is further strengthened.

[0042] Specifically, in one embodiment, regarding how the secondary hanging member 2 fixes the side of the thermal insulation board 3, as Figures 1 - 4 and Figure 9 shown, the secondary hanging member 2 includes a second clamping seat 28 and a first clamping seat 26. The second clamping seat 28 and the first clamping seat 26 both match the clamping groove 13, and a detachable limiting part is installed between the second clamping seat 28 and the first clamping seat 26. An installation cavity for abutting against the thermal insulation board 3 is formed between two adjacent limiting parts.

[0043] In this embodiment, after fixing the base frame 11 to the exterior wall of the building, the base frame 11 is connected to the connecting plate 19. Since the connection method between the connecting plate 19 and the base frame 11 is the same as that in the above embodiment, it will not be elaborated in this embodiment. After connecting the connecting plate 19 and the base frame 11, the side plates 111 on the upper and lower base frames 11 abut against the heat insulation board 3, and bolts are inserted into the first through holes 113 on the side plates 111 and the second through holes 115 on the extension plates 112 and rotated so that the bolts enter the heat insulation board 3, thereby fixing the heat insulation board 3. Then, the limiting part is installed between the first card seat 26 and the second card seat 28, and the first card seat 26 and the second card seat 28 are respectively engaged with the card slots 13, so that the limiting part is installed between two adjacent base frames 11. When the side plates 111 and the extension plates 112 fix the heat insulation board 3, the side of the heat insulation board 3 is reinforced by the limiting plate part abutting against the side of the heat insulation board 3.

[0044] In addition, in the present invention, regarding the above-mentioned limiting part, as Figure 9 shown, the limiting part includes a plurality of first positioning plates 21. The top of the first positioning plate 21 is recessed to form a second base hole 25, and the bottom of the first positioning plate 21 is fixedly connected with a first base head 22. The top of the first card seat 26 is recessed to form a first base hole 27. The first base head 22 is matched with the second base hole 25 and the first base hole 27. The bottom of the second card seat 28 is convexly fixedly connected with a second base head 29. The second base head 29 is matched with the second base hole 25 and the first base hole 27. A first positioning hole 23 is horizontally formed on the first positioning plate 21.

[0045] In this embodiment, the side plates 111 on the upper and lower base frames 11 abut against the heat preservation board 3, and bolts are inserted into the first through holes 113 on the side plates 111 and rotated in the second through holes 115 on the extension plates 112, so that the bolts enter the heat preservation board 3, thereby fixing the heat preservation board 3. Then, the required number of first positioning plates 21 are taken, and all the required number of first positioning plates 21 are stacked one above the other in sequence. The first base head 22 at the bottom of the first positioning plate 21 is screwed and connected with the second base hole 25 on another first positioning plate 21. According to the above steps, the required number of first positioning plates 21 are connected in sequence. Then, the first positioning plates 21 with adjusted lengths are placed between the first clamping seat 26 and the second clamping seat 28. The first positioning plates 21 with adjusted numbers are screwed and connected with the first base holes 27 on the first clamping seat 26 through the first base heads 22, and the first positioning plates 21 with adjusted numbers are screwed and connected with the second base heads 29 on the second clamping seat 28 through the second base holes 25. The first clamping seat 26 and the second clamping seat 28 are respectively engaged with the clamping grooves 13, so that the first positioning plates 21 with adjusted numbers are installed between two adjacent base frames 11. When the side plates 111 and the extension plates 112 fix the heat preservation board 3, the side of the heat preservation board 3 is abutted by the first positioning plate 21, and then the bolts pass through the first positioning holes 23 on the first positioning plate 21 and are screwed and connected with the side of the heat preservation board 3, thereby strengthening the side of the heat preservation board 3.

[0046] Since the thicknesses of the heat preservation boards 3 are different, for adjustment according to the thickness of the heat preservation board 3, as Figure 9 shown, a first side hole 24 is recessed on one side of the first positioning plate 21, and a plurality of second positioning plates 210 are arranged on the side of the first positioning plate 21 facing the first side hole 24. A side rod 211 is fixedly connected to one side of the second positioning plate 210, a second side hole 212 is recessed on the other side, and a second positioning hole 213 is horizontally formed on the second positioning plate 210. The second positioning hole 213 is located between the side rod 211 and the second side hole 212, and the side rod 211 matches the second side hole 212 and the first side hole 24.

[0047] In this embodiment, after the number of the first positioning plates 21 is adjusted, the adjusted first positioning plates 21 are screwed and connected to the second base heads 29 on the second card holders 28 through the second base holes 25. The first card holder 26 and the second card holder 28 are respectively engaged with the card slots 13, so that the adjusted first positioning plates 21 are installed between two adjacent base frames 11. After the side plates 111 and the extension plates 112 fix the heat preservation plate 3, the side surfaces of the heat preservation plate 3 are abutted by the first positioning plates 21. Then, the second positioning plates 210 are placed on one side of the first positioning plates 21, and the side rods 211 on one side of the second positioning plates 210 are screwed and connected to the first side holes 24 on the first positioning plates 21. According to the needs of the personnel, the required number of second positioning plates 210 are screwed and connected to the second side holes 212 on another second positioning plate 210 through the side rods 211, so that the required number of second positioning plates 210 are screwed and connected to the first positioning plates 21. Then, bolts are passed through the first positioning holes 23 on the first positioning plates 21 and the second positioning holes 213 on the second positioning plates 210 and then screwed and connected to the side surfaces of the heat preservation plate 3, so as to reinforce the side surfaces of the heat preservation plate 3.

[0048] Moreover, in the present invention, after the first card holder 26 and the second card holder 28 are connected to the card slot 13, in order to increase the stability of the positions of the first card holder 26 and the second card holder 28 after adjustment, as Figures 1 - 6 shown, two connecting grooves 14 are recessed on one side of the base frame 11 facing the side slot 16. The side slot 16 is located between the two connecting grooves 14. Second limiting rods 114 are screwed and connected inside the two connecting grooves 14. The free ends of the second limiting rods 114 extend into the connecting grooves 14 to abut against the first card holder 26 and the second card holder 28.

[0049] In this embodiment, the first card holder 26 and the second card holder 28 are pulled to move the first card holder 26 and the second card holder 28 along the card slot 13. When the first card holder 26 and the second card holder 28 move to the positions required by the personnel, the second limiting rods 114 are passed through the connecting grooves 14 and rotated, so that the free ends of the second limiting rods 114 are screwed and connected into the first card holder 26 and the second card holder 28. The first card holder 26 and the second card holder 28 are fixed at the positions required by the personnel by the abutment of the second limiting rods 114 against the base frame 11, so that the positions of the first card holder 26 and the second card holder 28 after adjustment are more fastened, and thus the first positioning plates 21 and the second positioning plates 210 are more fastened when fixing the heat preservation plate 3.

[0050] When the base frame 11 is fixed, in order to improve the fastening of the base frame 11, a flexible pad is bonded to one side of the base frame 11 away from the side slot 16, and protrusions are formed on the surface of the flexible pad.

[0051] When the heat preservation board 3 is on one side of the side plate 111 and the extension plate 112, so that the heat preservation board 3 is more firmly fixed after being fixed, positioning rods 15 are fixedly connected to the outside of the bottoms of the side plate 111 and the extension plate 112, and the positioning rods 15 on the side plate 111 and the extension plate 112 are inserted into the heat preservation board 3.

[0052] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
