Description

Invisible anchor bolts for exterior wall insulation and decorative panels and integrated quick-release panels for exterior wall insulation and decoration

Technical field:

The invention relates to an invisible anchor bolt of a building exterior wall insulation material, in particular to an invisible anchor bolt of an exterior wall insulation decorative panel and an integrated quick-installation panel for exterior wall insulation decoration, belonging to the technical field of building materials.

Background technique:

With the sustained, rapid and stable growth of China's economy, the rapid development of the construction industry, and the rapid expansion of the construction scale, the annual building area of our country is now more than the sum of the annual building area of all developed countries. It is predicted that in this country In the first two decades of the century, the construction industry will be a golden period of development. By 2010, the per capita construction area in urban areas will reach 26 square meters, and the per capita construction area in rural areas will reach 30 square meters. By 2020, the national housing construction area will reach 68.6 billion square meters meters, such a huge building scale is unprecedented in history and unique in the world. The recent decades in our country are the climax period of housing construction, and the building scale will increase significantly. Most of them are high-energy-consuming non-energy-saving buildings, and the remaining energy consumption seriously restricts the development of the country. Therefore, building energy conservation involves major public interests, and the national sustainable development strategy must be enforced by the state. Relevant government departments have taken necessary measures to implement building energy conservation, issued a series of documents, and formulated relevant norms and standards one after another. : If the construction unit violates the mandatory standards for building energy-saving design, the qualification certificate may be revoked and reworked if it is serious, and all buildings without external wall insulation will not be accepted. Therefore, building energy-saving activities have been vigorously carried out in the construction industry. External wall insulation and decoration have received attention, and have become a building energy-saving system promoted by the Ministry of Construction. At present, the external wall insulation mainly adopts two methods: "rubber powder polystyrene particle insulation system" and "expanded polystyrene board thin plaster external wall insulation system", but both have great defects. The disadvantages of the rubber powder polystyrene particle insulation system are: the whole process is carried out on the external wall, the construction is cumbersome, the thickness is not easy to grasp, and the interval time is long. When the thickness of the insulation layer is required to be large, multiple constructions are required, and the construction period will be longer. As a result, when the energy saving requirement reaches 65%, the application of the rubber powder polystyrene particle insulation system is restricted. In recent years, some cities have formulated mandatory regulations, strictly prohibiting the use of this system for external wall insulation, and mandating the use of EPS Board or XPS board as external wall insulation board. Although the external wall thermal insulation system with expanded polystyrene board and thin plaster is the best choice for external wall thermal insulation, there are still defects: the implementation process of the entire system still needs to be operated one by one on the external wall, the construction speed is slow, and the waste of materials is large. The construction cost is high. Therefore, the existing technical problems are as follows: first, to realize factory production, that is, to superimpose other layers on the insulation board in advance in the factory to produce finished quick-release boards, so that there is no need to construct the outer wall one by one , this problem has been basically solved; the second problem is how to attach the finished quick-release plate to the outer wall, which has not been really solved. CN2903239 discloses a utility model patent of "integrated board with exterior wall thermal insulation and wall paint coating". It is obviously unscientific to use steel wire to achieve the firmness of the board on the wall. From a mechanical point of view, the longer the length of the steel wire, the smaller the firmness (because the designed steel wire must be installed and fastened around the board. ), therefore, the length affects the sticking force of the board on the wall, and the balance of the board surface cannot be controlled, and the exposed steel wire will also produce a "cold and hot bridge" reaction. The steel wire is easy to corrode and affects the firmness, which brings safety. There are certain hidden dangers, and the yin and yang corners, lines, corners, doors, windows and openings of the building are even more difficult to operate. The construction has not been reduced, and the construction cost is still very high. CN2898168 discloses a utility model patent of "invisible anchor on the side of the composite insulation board". 600MM×1200MM board only install a few invisible anchors on its peripheral side, it is difficult to balance the force on the whole board, according to the characteristics of the polystyrene board’s own flexibility, the middle part will be hollow or protruding, resulting in Decreased adhesion and insufficient wind pressure resistance. In addition, the pressure sheet of the invisible anchor is designed in the middle layer of the side of the insulation board. The pressure area is too small and the pressure layer is too thin. If the insulation layer is too heavy or the wind pressure of the upper layer will give The safety of buildings brings certain hidden dangers. Therefore, in order to truly paste the factory-produced quick-release plate to the exterior wall safely and efficiently, the key problem that must be solved is that any number of anchors can be installed at any position of the quick-release plate, and it is also necessary to ensure that the anchorage through the anchorage When installing the quick release plate on the wall, the formed plate surface will not be damaged.

The presser foot and the fastener are connected through threads. One end of the connection is an external thread; or the presser foot is an external thread, and the end of the fastener connected with the presser foot is an internal thread. The fastener is provided with an outer pressure piece 4a perpendicular to the body itself, which divides the fastener into two sections, and the end connected to the presser foot is a threaded end. This part should be equal to or slightly shorter than the length of the presser foot to ensure When the two are tightened, the inner pressing piece and the outer pressing piece can tightly clamp the insulation board 7 in the middle, and the other end of the fastener is inserted into the mounting hole of the wall body 5, and its outer wall is provided with barbs 4b, which allow the It is bonded together with the cement in the wall installation hole, and the connection between the reinforced plate and the wall makes it impossible to be pulled out after being inserted into the installation hole. The surface of the outer pressure piece on the fastener is provided with reinforcing ribs along the radial direction 3c. The end with the barb is provided with an axial reinforcing rib 3d to enhance its hardness. The inner pressure sheet can be designed in any shape other than circle, such as triangle, quadrilateral, pentagon, hexagon, semicircle, oval, etc., to ensure that the inner pressure is not affected when the fastener is tightened on the presser foot. Sheet can not rotate in insulation board 7. Referring to Fig. 3 and Fig. 4, during the specific implementation, the first step is to install the inner pressure piece with cylindrical presser foot on the heat preservation board 7 of the specification, and punch holes on the heat preservation board according to the shape of the inner pressure piece. When pasting the veneer layer of tiles, the number of internal pressing sheets should be 6 pieces/ ^m2 . If the surface layer of paint composite board is pasted, it should be 4 pieces/ ^m2 . It is best to sag the surface of the insulation board by about 0.5MM. The second step is to attach other layers one by one to the insulation board that has been installed with the inner pressure sheet. For example, to attach a composite board or an aluminum-plastic board, apply an interface agent directly on the insulation board, and then stick the composite board or aluminum-plastic board. It can be ready for use after compacting and flattening; if it is attached to the tile facing layer, first apply the interface agent, then apply the alkali-resistant broken fiber mesh cloth or steel wire mesh, and then apply the waterproof and crack-resistant plastering mortar.
