Description

Technical Field

[0001] This application relates to the field of prefabricated wall panels, and more particularly to an assembled insulated wall panel. Background Technology

[0002] With increasingly stringent requirements for building energy conservation, wall insulation technology has become a key development direction in the construction industry. Furthermore, with the promotion of prefabricated buildings, precast insulated wall panel technology is being increasingly applied to building insulation walls due to its advantages such as high construction efficiency and ease of installation.

[0003] Currently, prefabricated insulated wall panels mainly use two types: precast concrete sandwich insulated panels and metal frame composite insulated panels. The insulated wall panels can be anchored to the structural layer of the wall using anchor nails.

[0004] While anchoring the insulation wall panels to the wall ensures their stability, it often makes it difficult to guarantee the airtightness of the joints between adjacent insulation wall panels, which greatly reduces the insulation performance of the insulation wall panels. Utility Model Content

[0005] In order to improve the thermal insulation performance at the joints of adjacent prefabricated insulated wall panels, this application provides a prefabricated insulated wall panel.

[0006] The prefabricated insulated wall panel provided in this application adopts the following technical solution: A prefabricated insulated wall panel includes a wall panel body, a first connecting strip, a second connecting strip, and a locking mechanism. The first connecting strip is provided on two adjacent sides of the wall panel body, and the second connecting strip is provided on two other sides of the wall panel body opposite to the first connecting strip. The second connecting strip is used to attach to the first connecting strip on an adjacent wall panel body. The contact surfaces of the second connecting strip and the first connecting strip are inclined. The locking mechanism is provided on the second connecting strip and is used to lock the second connecting strip and the first connecting strip.

[0007] By adopting the above technical solution, the construction personnel first install one wall panel onto the structural layer of the wall, and then move another wall panel so that the second connecting strip of the other wall panel fits onto the first connecting strip of the wall panel already positioned on the wall. The second connecting strip is positioned on the first connecting strip by the locking mechanism, and the other wall panel is then positioned and installed on the wall. At this time, the second connecting strip presses against the first connecting strip, sealing the joint between adjacent wall panels, improving the airtightness of the joint between adjacent wall panels, and thus improving the thermal insulation performance of the joint between adjacent prefabricated insulated wall panels.

[0008] Optionally, the locking mechanism includes a control button and a locking block. The control button is rotatably mounted on the second mating bar, and the locking block is mounted on the control button. The first mating bar has a groove for the locking block to be inserted into, and the side wall of the groove has a locking slot for the locking block to be rotated into.

[0009] By adopting the above technical solution, when moving another wall panel body so that the second mating strip on the other wall panel body is attached to the first mating strip on the installed wall panel body, the locking block is first embedded in the groove. After the second mating strip is attached to the first mating strip, the control button is turned. The control button drives the locking block to rotate into the lock groove. The locking block abuts against the side wall of the lock groove, which can easily lock the second mating strip on the first mating strip.

[0010] Optionally, the cross-sectional dimensions of the locking block gradually increase from the direction away from the control button to the direction closer to the control button.

[0011] By adopting the above technical solution, when the lock block is inserted into the lock groove, the lock block, whose cross-sectional size gradually increases from away from the control button to close to the control button, is pressed against the side wall of the lock groove, so that the second mating strip is pressed against the first mating strip, thereby improving the tightness of the fit between the second mating strip and the first mating strip.

[0012] Optionally, the control button is embedded in the second mating strip.

[0013] By adopting the above technical solution, the control button embedded in the second connecting strip improves the flatness of the second connecting strip, making it easier to carry out subsequent construction on the second connecting strip.

[0014] Optionally, the control button has a cross-shaped groove.

[0015] By adopting the above technical solution, construction workers can easily drive the control knob to rotate by inserting a screwdriver into the cross-shaped groove.

[0016] Optionally, the second mating strip is provided with a sealing strip, and the first mating strip is provided with a sealing groove for the sealing strip to be embedded.

[0017] By adopting the above technical solution, when the second mating strip is attached to the first mating strip, the sealing strip is embedded in the sealing groove to seal the gap between the second mating strip and the first mating strip, thereby improving the airtightness between the second sealing strip and the first sealing strip.

[0018] Optionally, the second mating bar is provided with a positioning protrusion, and the first mating bar is provided with a positioning groove for the positioning protrusion to be inserted.

[0019] By adopting the above technical solution, when the wall panel to be installed is moved for installation, the positioning protrusion on the second mating strip on the wall panel to be installed is inserted into the positioning groove on the first mating strip on the wall panel to be installed. The side wall of the positioning groove supports the positioning protrusion, which supports the wall panel to be installed, making it easier to position and install the wall panel to be installed on the wall.

[0020] Optionally, the opening width of the positioning groove is greater than the diameter of the positioning protrusion, and a locking groove with an opening width consistent with the diameter of the positioning protrusion is provided on the bottom wall of the positioning groove.

[0021] By adopting the above technical solution, the positioning protrusion on the wall panel body to be installed is first inserted into the positioning groove on the first mating strip on the installed wall panel body. Then, the wall panel body to be installed is moved. After the positioning protrusion is aligned with the locking groove, the positioning protrusion is engaged in the locking groove, thus positioning the wall panel body to be installed. By first inserting the positioning protrusion into the positioning groove with a larger opening, it is easier to position the wall panel body to be installed.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The second mating strip squeezes the first mating strip to seal the joint between adjacent wall panels, thereby improving the airtightness of the joint between adjacent wall panels and thus improving the thermal insulation performance of the joint between adjacent prefabricated insulated wall panels. 2. Insert the positioning protrusion into the positioning groove with a large opening to facilitate positioning the wall panel body to be installed. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] This application discloses a prefabricated thermal insulation wall panel.

[0029] Reference Figure 1 The prefabricated insulated wall panel includes a wall panel body 1, a first connecting strip 2, a second connecting strip 3, and a locking mechanism 4. The wall panel body 1 can be a cement foam insulation board, a rock wool composite board, a magnesium oxide foam exterior wall insulation board, etc. In this embodiment, the wall panel body 1 is a cement foam insulation board.

[0030] Reference Figure 1 The first connecting strip 2 is installed on two adjacent sides of the wall panel body 1, and the second connecting strip 3 is installed on two other adjacent sides of the wall panel body 1 opposite to the two first connecting strips 2. The second connecting strip 3 is used to connect and adhere to the first connecting strip 2 on the adjacent wall panel body 1. The mating surfaces of the second connecting strip 3 and the first connecting strip 2 are inclined.

[0031] The construction workers first position and install one wall panel body 1 onto the structural layer of the wall. Then, they move another wall panel body 1 for installation, so that the second connecting strip 3 on the other wall panel body 1 fits onto the first connecting strip 2 of the already positioned wall panel body 1. Then, they position and install the other wall panel body 1 onto the structural layer of the wall, so that the second connecting strip 3 presses against the first connecting strip 2. The second connecting strip 3 and the first connecting strip 2 can seal the joint between adjacent wall panel bodies 1, improve the airtightness of the joint between adjacent wall panel bodies 1, and thus improve the thermal insulation performance of the joint between adjacent prefabricated insulated wall panels.

[0032] Reference Figure 1 , Figure 2 A sealing strip 5 is installed on the second connecting strip 3. In this embodiment, the sealing strip 5 is a water-swellable sealing strip with a U-shaped cross section. A sealing groove 23 is provided on the first connecting strip 2, which is used for the sealing strip 5 to be embedded.

[0033] When the second mating strip 3 of the wall panel body 1 to be installed is attached to the first mating strip 2 of the wall panel body 1, the sealing strip 5 is embedded in the sealing groove 23 and the sealing strip 5 is pressed against the side wall of the sealing groove 23, thereby sealing the second mating strip 3 and the first mating strip 2 and improving the airtightness between the second sealing strip 5 and the first sealing strip 2.

[0034] Reference Figure 1 , Figure 2 The second mating strip 3 is equipped with a positioning protrusion 6, and the first mating strip 2 is provided with a positioning groove 24. The opening width of the positioning groove 24 is greater than the diameter of the positioning protrusion 6. A locking groove 25 is provided on the bottom wall of the positioning groove 24 in communication with the positioning groove 24. The opening width of the locking groove 25 is the same as the diameter of the positioning protrusion 6.

[0035] When the wall panel to be installed is moved to the wall panel body 1 for assembly, the second protrusion on the second mating strip 3 of the wall panel body 1 first engages with the positioning groove 24 to initially position the wall panel body 1. Then, the wall panel body 1 is moved so that the positioning protrusion 6 slides within the positioning groove 24. When the positioning protrusion 6 slides to be opposite the locking groove 25, the wall panel body 1 can then be driven by gravity to engage the positioning protrusion 6 into the locking groove 25. The side wall of the locking groove 25 limits the positioning protrusion 6, thereby supporting and positioning the wall panel body 1, which facilitates the subsequent positioning and installation of the wall panel body 1 on the wall. Furthermore, by first inserting the positioning protrusion 6 into the positioning groove 24 with a relatively large opening and then engaging the locking groove 25, the difficulty of moving the wall panel body 1 to be installed and engaging the positioning protrusion 6 into the locking groove 25 is reduced, making it easier to position the wall panel body 1.

[0036] Reference Figure 1 , Figure 3 The locking mechanism 4 is installed on the second connecting strip 3. The locking mechanism 4 is used to lock the second connecting strip 3 and the first connecting strip 2. The locking mechanism 4 includes a control button 41 and a locking block 42. The control button 41 is rotatably mounted on the second connecting strip 3 and is embedded within it. The control button 41 has a cross-shaped groove. The embedded control button 41 makes the surface of the second connecting strip 3 smoother, facilitating subsequent construction on the second connecting strip 3. The cross-shaped groove on the control button 41 also allows construction workers to easily insert tools such as screwdrivers and then conveniently drive the control button 41 to rotate.

[0037] Reference Figure 1 , Figure 3 The locking block 42 is installed on the control button 41. The cross-sectional size of the locking block 42 gradually increases from the direction away from the control button 41 to the direction closer to the control button 41. A groove 21 is provided on the first mating strip 2 for the locking block 42 to be inserted. A locking groove 22 is provided on the side wall of the first mating strip 2 that is connected to the groove 21 near the bottom wall.

[0038] When moving the device to be installed on the wall panel for assembly, first allow the locking block 42 to enter the recess 21. After the locking block 42 is aligned with the locking groove 22, turn the control button 41. The control button 41 drives the locking block 42 to rotate, and the locking block 42 can rotate into the locking groove 22. The locking block 42 abuts against the side wall of the locking groove 22, which can easily lock the second connecting strip 3 onto the first connecting strip 2. During the process, the locking block 42, whose cross-sectional size gradually increases from away from the control button 41 to closer to the control button 41, squeezes against the side wall of the locking groove 22, so that the second connecting strip 3 is pressed tightly against the first connecting strip 2, improving the tightness of the fit between the second connecting strip 3 and the first connecting strip 2.

[0039] The implementation principle of a prefabricated insulated wall panel in this application embodiment is as follows: The construction personnel first position and install one wall panel body 1 onto the wall structure layer, and then move another wall panel body 1 so that the positioning protrusion 6 on the other wall panel body 1 is inserted into the positioning groove 24. Then, the other wall panel body 1 is moved laterally so that the positioning protrusion 6 is engaged in the locking groove 25. At this time, the lateral position of the other wall panel body 1 is positioned, and the locking block 42 on the second connecting strip 3 on the other wall panel body 1 is opposite to the groove 21. Press the other wall panel body 1, and the locking block 42 is inserted into the groove 21. Then, turn the control knob 41 so that the locking block 42 is turned into the locking groove 22, and the second connecting strip 3 is locked on the first connecting strip 2. After the other wall panel body 1 is positioned and installed on the wall, the second connecting strip 3 and the first connecting strip 2 are squeezed together. With the cooperation of the sealing strip 5, the joint between adjacent wall panel bodies 1 is sealed, improving the airtightness of the joint between adjacent wall panel bodies 1, thereby improving the thermal insulation performance of the joint between adjacent prefabricated insulated wall panels.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
