Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation boards and wall connectors, in particular to a thermal insulation bridge anchor for a protective wall panel. Background Art

[0002] Energy conservation in buildings is the most basic requirement for modern buildings, and external wall insulation is the most common form of building insulation. Traditional external wall insulation is the laying and installation of external wall insulation panels after the main building project is completed. With the development of prefabricated buildings and the improvement of insulation requirements, a kind of insulation composite panel, also known as enclosure wall panel, has emerged, which is cast-in-place with the main building. With the further development of prefabricated buildings and the improvement of insulation requirements, a kind of prefabricated wall panel that combines insulation and external wall enclosure functions in the factory has emerged, namely, prefabricated building external insulation enclosure wall panel, referred to as enclosure wall panel. The enclosure wall panel is a multi-layer structure, and the layers are bonded together by adhesives or by insulation bonding with self-adhesive function. However, if only by bonding, the enclosure wall panels will be delaminated after a period of time. If the outer layer of the enclosure wall panels falls off, it will cause a very serious safety accident, which may easily lead to a vicious incident of falling and injuring people. Therefore, the structure of the enclosure wall panels needs to be combined with bonding and anchoring. The anchor connectors currently used are mostly metal connectors. This type of connector is relatively strong, but the disadvantage is that it will form a hot and cold bridge for heat conduction between indoor and outdoor, thereby reducing the insulation effect of the external insulation layer on the building.

Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0024] Embodiment 1:

[0025] like Figure 1 and Figure 5As shown, a heat-insulating bridge anchor for a protective wall panel comprises a metal plate 1, a metal screw 2 perpendicular to the metal plate 1 is welded at the center thereof, a first cold and hot bridge partition part 3 is injection-molded on the periphery of the metal plate 1, a second cold and hot bridge partition part 4 is injection-molded on the periphery of the metal screw 2, the central axis of the metal screw 2 coincides with the central axis of the second cold and hot bridge partition part 4, a threaded portion 12 is extended from the end of the metal screw 2 and the second cold and hot bridge partition part 4 is provided, a tensioning portion used in conjunction with the metal plate 1 is assembled on the threaded portion 12; the first cold and hot bridge partition part 3 and the second cold and hot bridge partition part 4 are integrally injection-molded. When in use, the metal plate 1 is located on one side of the enclosure wallboard, and the tensioning part is located on the other side of the enclosure wallboard, and the two are connected by metal screws 2. The metal plate 1 and the tensioning part form a tensioning effect on the multi-layer structure of the enclosure wallboard, and the layers are no longer simply bonded by mortar, but the bonding and anchoring are combined, and the enclosure wallboard is not prone to stratification, which avoids the probability of safety accidents. The utility model can be used not only for fixing the enclosure wallboard, but also for fixing the enclosure wallboard to the main frame 14, and has a wide range of uses. The utility model has a simple structure, realizes bonding and anchoring of the enclosure wallboard, has a firm connection, blocks cold and hot bridges, and has good safety.

[0026] like Figure 1 As shown, the tensioning part is a second nut 10 threadedly mounted on the threaded part 12, and the outer periphery of the second nut 10 is injection molded with a cylindrical hot and cold bridge partition three parts 5. The first installation grooves 51 are distributed in a circumferential array on the hot and cold bridge partition three parts 5. The outer diameter of the hot and cold bridge partition three parts 5 is roughly equal to the outer diameter of the hot and cold bridge partition one part 3. The second nut 10 in this embodiment not only plays a role in tightening, but also plays a role in forming a pulling force between the hot and cold bridge partition one part 3. Therefore, the outer diameter of the second nut 10 is as large as possible, and the hot and cold bridge partition three parts 5 injection molded outside the second nut 10 are preferably cylindrical. The hot and cold bridge partition three parts 5 and the hot and cold bridge partition one part 3 are roughly equal in outer diameter, which can effectively form a balance of pulling force and make the connection more stable. The first installation groove 51 can be a pit, a groove, a blind hole or a through hole, the purpose of which is to facilitate the grip of the wrench during installation and to facilitate installation. Therefore, there is no requirement for its shape and number, as long as it can provide convenience for the installation of the wrench. A transition cone 7 is provided at the junction of the ends of the two cold and hot bridge partition parts 4 and the metal screw 2. The transition cone 7 can save effort when installing the metal screw 2 and make the transition smoother.

[0027] The first cold and hot bridge partition part 3, the second cold and hot bridge partition part 4 and the third cold and hot bridge partition part 5 are made of one of PP, PPR, PVC, PE and PA materials. Injection molding is a prior art, and those skilled in the art can know the injection molding process, which will not be described in detail here.

[0028] Embodiment 2:

[0029] like Figure 2As shown, the technical scheme of this embodiment is basically the same as that of the first embodiment, and the difference is that the tension part is a stepped nut 11 threadedly mounted on the threaded part 12, the stepped nut 11 includes an integrally formed large outer diameter end and a small outer diameter end, the small outer diameter end is close to the end of the metal screw 2, and the outer periphery of the stepped nut 11 is injection molded with a cylindrical hot and cold bridge partition four parts 6. The circumferential array on the hot and cold bridge partition four parts 6 is distributed with a second mounting groove 61. The outer diameter of the hot and cold bridge partition four parts 6 is roughly equal to the outer diameter of the hot and cold bridge partition one part 3. The stepped nut 11 in this embodiment includes a large outer diameter end and a small outer diameter end, and its main purpose is to save materials on the basis of the second embodiment, which not only ensures the balance of tension, but also further reduces the material of the nut and saves costs. The hot and cold bridge partition four parts 6 injected on the outside of the stepped nut 11 are preferably cylindrical, and the hot and cold bridge partition four parts 6 are roughly equal to the outer diameter of the hot and cold bridge partition one part 3, which can effectively form a balance of tension and make the connection more stable. The second installation groove 61 can be a pit, a groove, a blind hole or a through hole. The purpose is to facilitate the grip of the wrench during installation and to facilitate installation. Therefore, there is no requirement for its shape and number, as long as it can facilitate the installation of the wrench.

[0030] Embodiment three:

[0031] like Figure 3 As shown, the technical solution of this embodiment is basically the same as that of the first embodiment, and the difference is that the tension part includes a gasket 9 and a first nut 8 which are sleeved on the threaded part 12, and the first nut 8 is threadedly installed on the threaded part 12, and the first nut 8 is close to the end of the metal screw 2. The gasket 9 is an annular gasket 9, and the outer diameter of the gasket 9 is larger than the outer diameter of the first nut 8, and the outer diameter of the gasket 9 is consistent with the outer diameter of the cold and hot bridge partition part 3, and the thickness of the gasket 9 is less than the thickness of the first nut 8. The outer diameter of the gasket 9 is consistent with the outer diameter of the cold and hot bridge partition part 3, which can effectively form a balance of tension and make the connection more stable. The outer diameter of the first nut 8 does not need to be very large, because the first nut 8 plays the role of fixing the gasket 9, and the tension between the first nut 8 and the cold and hot bridge partition part 3 mainly depends on the gasket 9, so the outer diameter of the gasket 9 is as large as possible, preferably consistent with the outer diameter of the cold and hot bridge partition part 3.

[0032] Embodiment 4:

[0033] like Figure 4 As shown, this embodiment is basically the same as the first embodiment, except that:

[0034] The tensioning part is a third nut 15 threadedly mounted on the threaded part 12, and the outer diameter of the third nut 15 is substantially equal to the outer diameter of the metal plate 1. A tensioning space is formed between the third nut 15 and the metal plate 1, and the thickness and diameter of the third nut 15 are both greater than the first nut 8. The third nut 15 combines the functions of the gasket 7 and the first nut 8 into one.

[0035] Embodiment five:

[0036] like Figure 5 As shown, the technical solution of this embodiment is basically the same as that of the third embodiment, except that the outer peripheral surface of the second part 4 of the cold and hot bridge partition is integrally injection molded with barbs 13. The barbs 13 further increase the contact area between the second part 4 of the cold and hot bridge partition and the surrounding wallboard, making the connection between the two more secure. The barbs 13 can be added not only to the third embodiment, but also to the first, second and fourth embodiments, all within the protection scope of the present utility model. The spacing of the barbs 13 is preferably consistent, and the length of the barbs 13 is also preferably consistent.

[0037] The metal plate 1 in Examples 1 to 5 is preferably a circular metal plate, and a through hole may be provided on the metal plate 1. The through hole can save the raw materials of the metal plate 1 on the one hand, and can increase the contact area between the metal plate 1 and the mortar when applying the mortar on the other hand, thereby increasing the bonding strength.

[0038] like Figure 5 As shown, the use state diagram of the first and third embodiments of the utility model. The first embodiment is used for fixing the enclosure wallboard, and the third embodiment is used for fixing the enclosure wallboard and the main frame, which has a wide range of uses.

[0039] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
