Description

Technical Field

[0001] This invention relates to a prefabricated external wall panel installation device and method, belonging to the field of building construction technology. Background Technology

[0002] Prefabricated exterior wall panels are factory-prefabricated wall panels that are integrated with the building structure and attached to the main structure. They combine multiple functions such as heat insulation, waterproofing, and aesthetics, and have a high degree of industrialization. Based on the connection method between the prefabricated exterior wall panels and the main structure, they are divided into two types: point-supported and line-supported. Point-supported exterior wall panels are more widely used because they can be installed after the main structure is completed.

[0003] However, highly integrated prefabricated exterior wall panels require high precision. To achieve design goals and ensure the functionality and aesthetics of the exterior envelope, the corresponding construction and installation precision requirements are also correspondingly high. Currently, to control the precise placement of the wall panels and ensure the joint width during construction and installation, manual labor is often used in stages with the aid of tools such as diagonal braces. This method is inefficient and costly in terms of precision control. Summary of the Invention

[0004] To address the problems existing in the installation process of prefabricated external wall panels, this invention provides a prefabricated external wall panel installation device and method, which can improve the accuracy and efficiency of adjusting the positioning during the installation of prefabricated external wall panels.

[0005] To solve the above technical problems, the present invention includes the following technical solutions:

[0006] An assembly-type external wall panel installation device includes an upper limit mechanism, a lower limit mechanism, a first connecting support, a first adjusting pressure plate, a second connecting support, and a second adjusting pressure plate;

[0007] The upper limit mechanism includes an upper limit panel and a sliding vertical baffle. A boss is provided on one side of the upper limit panel. A horizontal groove is provided above the boss. A vertical slot is provided in the middle of the boss and on the adjacent upper limit panel. The sliding vertical baffle is provided in the vertical slot and can slide up and down.

[0008] The lower limit mechanism includes a lower limit panel and a fixed vertical baffle. A cantilever plate is provided on one side of the lower limit panel, and a fixed vertical baffle plate is provided in the middle of the cantilever plate. A horizontal sliding groove is provided above the fixed vertical baffle plate.

[0009] One end of the first connecting support and the second connecting support is used to fix it to the main structure, and the other end is provided with a connecting protrusion, which is respectively set in the first slide groove and the second slide groove and can slide.

[0010] The first connecting support and the second connecting support are each provided with a first sliding member along their length direction, and the first adjusting plate and the second adjusting plate are each provided with a second sliding member; the first adjusting plate is parallel to and spaced apart from the upper limit panel, and the second adjusting plate is parallel to and spaced apart from the lower limit panel; the first sliding member and the second sliding member are slidably connected to adjust the distance between the first adjusting plate and the upper limit panel, and the distance between the second adjusting plate and the lower limit panel.

[0011] Furthermore, the first connecting support and the second connecting support are adjustable in length. Both the first connecting support and the second connecting support include an outer sleeve and an inner sleeve. One end of the inner sleeve is inserted into the outer sleeve, and a connecting protrusion is set at the other end of the inner sleeve. The outer sleeve and the inner sleeve can slide along the length direction and are braked by fastening bolts.

[0012] Furthermore, the first sliding member is a sliding rail, and the second sliding member is a sliding groove that matches the sliding rail. The sliding groove is engaged with the sliding rail and can slide and brake; or,

[0013] The first sliding member is a sliding groove, and the second sliding member is a sliding rail that matches the sliding groove. The sliding rail is snapped into the sliding groove and can slide and brake.

[0014] Furthermore, when the sliding vertical baffle is located at the top of the vertical slot, the bottom height of the sliding vertical baffle is not lower than the lower surface height of the boss; when the sliding vertical baffle is located at the bottom of the vertical slot, the bottom height of the sliding vertical baffle is lower than the lower surface height of the boss.

[0015] Accordingly, the present invention also provides an installation method for prefabricated external wall panels, which is constructed using the aforementioned prefabricated external wall panel installation device. The installation method includes the following steps:

[0016] S1. The first connecting support and the second connecting support are fixedly connected to the main structure respectively. The upper limit panel and the lower limit panel are respectively attached to the surface of the wall panel one, and the height meets the requirements. The connection position of the first connecting support is set above the top corner of the horizontally adjacent wall panel one. The second connecting support is set diagonally with the first connecting support, and the connection positions of the first connecting support and the second connecting support are both located in the adjacent area of ​​the installation position.

[0017] S2. Slide the upper limit panel and the lower limit panel to outside the installation position of the second wall panel, and adjust the distance between the first adjusting pressure plate and the upper limit panel, and the distance between the second adjusting pressure plate and the lower limit panel to the maximum to leave space for the hoisting of the second wall panel;

[0018] S3. Hoist wall panel two to the installation position; slide the upper limit panel until the sliding vertical baffle slides down from the upper part of the boss, so that the top corner of wall panel two abuts against the sliding vertical baffle, and the sliding vertical baffle abuts against wall panel one; slide the lower limit panel until the fixed vertical baffle is in contact with the side of wall panel two;

[0019] S4. Push the first adjusting plate to make the second wall panel fit against the upper limit panel, and push the second adjusting plate to make the second wall panel fit against the lower limit panel, thus completing the installation position correction and adjustment of the second wall panel;

[0020] S5. Connect wall panel two to the main structure via point supports;

[0021] S6. Loosen the first and second adjusting pressure plates, remove the connection between the first and second connecting supports and the main structure, and remove the installation device of the prefabricated external wall panel.

[0022] Furthermore, the lengths of the first connecting support and the second connecting support are adjustable. In step S1, by adjusting the lengths of the first connecting support and the second connecting support, the upper limit panel and the lower limit panel are respectively attached to a surface of the wall panel.

[0023] The present invention, by adopting the above technical solutions, has the following advantages and positive effects compared with the prior art: The prefabricated external wall panel installation device and method provided by the present invention allows for a slidable connection between the upper limit panel and the first connecting support, and a slidable connection between the lower limit panel and the second connecting support. During the hoisting of the prefabricated external wall panel to be installed, the upper and lower limit panels can be slid out of the installation position, leaving operating space for hoisting. The sliding vertical baffle can slide up and down in the vertical slot without affecting the left and right movement of the upper limit panel, and can also control the width of the joint. After the prefabricated external wall panel to be installed is hoisted into place, the first and second adjusting pressure plates press the prefabricated external wall panel to be installed, so that the surface of the prefabricated external wall panel to be installed is in contact with the upper and lower limit panels, thus ensuring that the surface of the prefabricated external wall panel to be installed is flush with the surface of the prefabricated external wall panel already installed. Therefore, this invention provides a tool-type installation device by using adjacent prefabricated exterior wall panels that have already been constructed as limiting references to quickly correct the three-dimensional installation position of the wall panels, thereby improving installation accuracy and adjustment efficiency, ensuring the overall facade effect of the wall panels and controlling the joint size between the wall panels.

[0037] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed explanation of the prefabricated external wall panel installation device and method provided by the present invention. The advantages and features of the present invention will become clearer from the following description. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0038] Example 1

[0039] like Figure 1As shown, the prefabricated external wall panel installation device provided in this embodiment is used to precisely install the prefabricated external wall panels onto the main structure 1. The main structure 1 is typically a steel component installed on the load-bearing structure of a building, such as I-beams, channel steel, angle steel, connecting steel pipes, etc. The main structure 1 includes several rows of steel components, with the installation height of adjacent rows of steel components matching the top and bottom installation heights of the prefabricated external wall panels, respectively. The prefabricated external wall panels include prefabricated external wall panels that have been completed and prefabricated external wall panels to be installed. The prefabricated external wall panels that have been completed are designated as wall panel one 2, and the prefabricated external wall panels to be installed are designated as wall panel two 3. The installation device is used to control the height and verticality of wall panel two 3 and to make the outer surface of wall panel two 3 flush with wall panel one 2.

[0040] Combination Figures 1 to 7 As shown, the installation device includes an upper limit mechanism 10, a lower limit mechanism 20, a first connecting support 30, a second connecting support 50, a first adjusting pressure plate 40, and a second adjusting pressure plate 60.

[0041] Combination Figures 1 to 5 As shown, the upper limit mechanism 10 includes an upper limit panel 11 and a sliding vertical baffle 12. A boss 112 is provided on one side of the upper limit panel 11, and the lower surface of the boss 112 matches the top shape of the prefabricated exterior wall panel. Typically, the top of the prefabricated exterior wall panel is tongue-and-groove shaped, and the lower surface of the boss 112 is set as a stepped shape to cooperate with the tongue-and-groove. Two horizontally spaced vertical grooves 111 are provided above the boss 112. Vertical slots 113 are provided in the middle of the boss 112 and on the adjacent upper limit panel 11. The sliding vertical baffle 12 is disposed in the vertical slot 113. When the sliding vertical baffle 12 is located at the top of the vertical slot 113, the bottom height of the sliding vertical baffle 12 is not lower than the lower surface height of the boss 112. When the sliding vertical baffle 12 is located at the bottom of the vertical slot 113, the bottom height of the sliding vertical baffle 12 is lower than the lower surface height of the boss 112. The thickness of the sliding vertical baffle 12 is matched with the width of the vertical joint, which is used to control the width of the vertical joint between wall panel 2 and the adjacent wall panel 1.

[0042] Combination Figures 1 to 4As shown, one end of the first connecting support 30 is provided with a bolt hole and is connected to the main structure 1 by bolts. The other end is provided with a connecting protrusion 31, which is set in the sliding groove 111. After the first connecting support 30 is fixed to the main structure 1, the upper limit panel 11 can move left and right. As an example, the first connecting support 30 includes an outer sleeve 32 and an inner sleeve 33. One end of the inner sleeve 33 is inserted into the outer sleeve 32, and the other end of the inner sleeve 33 is provided with the connecting protrusion 31. The outer sleeve 32 and the inner sleeve 33 can slide and brake along the length direction. Braking can be accomplished by setting fastening bolts on the outer sleeve 32. This setting allows the length of the first connecting support 30 to be adjusted as needed, thereby accurately adjusting the distance between the upper limit panel 11 and the main structure 1, so that the position of the upper limit panel 11 matches the position of the wall panel 2, improving the fit between the upper limit panel 11 and the wall panel 2. The first connecting support 30 is telescopically adjustable, which can also reduce the installation accuracy of the first connecting support 30 and improve the installation efficiency of the first connecting support 30. A first sliding member 34 is provided along the length direction of the first connecting support 30. The first sliding member 34 is a sliding rail (or sliding groove). For example, a sliding rail is provided on the outer wall of the bottom or side of the inner sleeve 33 of the first connecting support 30. The sliding rail is used to connect with the first adjusting pressure plate 40.

[0043] The first adjusting plate 40 includes a cantilever end, and the cantilever end is provided with a second sliding member 41. The second sliding member 41 is a sliding groove (or sliding track). The sliding groove (or sliding track) matches the sliding track (or sliding groove) on the first connecting support 30, so that the first adjusting plate 40 can be finely adjusted in position, thereby adjusting the distance between it and the upper limit panel 11.

[0044] In use, the upper limit mechanism 10, the first connecting support 30, and the first adjusting pressure plate 40 cooperate as follows: The first connecting support 30 is fixedly connected to the main structure 1, and the connection position is set at the top corner of the installation position of the second wall panel 3, and above the top corner of the adjacent first wall panel 2. The upper limit panel 11 is slid to one end, outside the installation position, so as not to affect the hoisting of the second wall panel 3. The length of the first connecting support 30 is adjusted so that the upper limit panel 11 is in contact with the surface of the first wall panel 2. After the second wall panel 3 is hoisted, the upper limit panel 11 is slid. When the sliding vertical baffle 12 is located at the joint, it slides down from the vertical slot 113. The width of the joint can be controlled by sliding the vertical baffle 12. The first adjusting pressure plate 40 is slid and presses the second wall panel 3 so that the surface of the second wall panel 3 is in contact with the upper limit panel 11. The upper limit panel 11 is in contact with the surfaces of the first wall panel 2 and the second wall panel 3. At this time, the surface of the second wall panel 3 is flush with the surface of the first wall panel 2.

[0045] The lower limit mechanism 20 includes a lower limit panel 21 and a fixed vertical baffle 22. A cantilever plate 212 is provided on one side of the lower limit panel 21. The upper surface of the cantilever plate 212 matches the bottom shape of the second wall panel 3, and the lower surface of the cantilever plate 212 matches the bottom shape of the first wall panel 2. Its thickness matches the width of the transverse joint. The fixed vertical baffle 22 is located in the middle of the cantilever plate 212. Two sliding grooves 211 are provided above the fixed vertical baffle 22 for sliding connection with the end of the second connecting support 50.

[0046] One end of the second connecting support 50 is connected to the main structure 1 by bolts, and the other end is provided with a connecting protrusion 31, which is disposed in the second sliding groove 211. After the second connecting support 50 is fixed to the main structure 1, the lower limit panel 21 can move left and right. The second adjusting pressure plate 60 is fixedly connected to the second connecting support 50. The second adjusting pressure plate 60 is arranged parallel to and spaced apart from the lower limit panel 21, and the second adjusting pressure plate 60 can move along the length direction of the second connecting support 50, thereby adjusting the distance between it and the lower limit panel 21. The specific structure of the second connecting support 50 and the second adjusting pressure plate 60 can be referred to the first connecting support 30 and the first adjusting pressure plate 40, and will not be described in detail here.

[0047] In use, the lower limit mechanism 20, the second connecting support 50, and the second adjusting pressure plate 60 cooperate as follows: The second connecting support 50 is fixedly connected to the main structure 1, and the connection position is set at the bottom corner of the installation position of the second wall panel 3, and is located outside the current installation position, so as not to affect the hoisting of the second wall panel 3; the length of the second connecting support 50 is adjusted so that the lower limit panel 21 is in contact with the surface of the first wall panel 2 below; after the second wall panel 3 is hoisted, the lower limit panel 21 is slid, and when the fixed vertical baffle 22 abuts against the side of the second wall panel 3, the second adjusting pressure plate 60 slides and presses the second wall panel 3, so that the surface of the second wall panel 3 is in contact with the lower limit panel 21, and the upper limit panel 11 is in contact with the surfaces of both the first wall panel 2 and the second wall panel 3. At this time, the surface of the second wall panel 3 is flush with the surface of the first wall panel 2.

As an example, the lengths of the first connecting support 30 and the second connecting support 50 are adjustable. By adjusting the lengths of the first connecting support 30 and the second connecting support 50, the upper limit panel 11 and the lower limit panel 21 are attached to the surface of the wall panel 2. The connection position of the first connecting support 30 is set above the top corner of the horizontally adjacent wall panel 2, and the second connecting support 50 is set diagonally to the first connecting support 30 and is set on the main structure 1 at the position adjacent to the bottom corner of the wall panel 3. The height of the lower surface of the boss 112 and the height of the upper surface of the cantilever plate 212 both meet the requirements. When a deviation occurs, a shim is set between the first connecting support 30, the second connecting support 50 and the main structure 1 to ensure that the heights of the boss 112 and the cantilever plate 212 meet the requirements.

[0051] S2. Slide the upper limit panel 11 and the lower limit panel 21 to positions outside the installation positions of the second wall panel 3.

The sliding vertical baffle 12 is set in the vertical slot 113 and its bottom is located on the first wall panel 2.

[0052] S3. Hoist wall panel 2 (3) to the installation position; slide the upper limit panel 11 until the sliding vertical baffle 12 slides down from the top of the boss 112, so that the top corner of wall panel 2 (3) abuts against the sliding vertical baffle 12, and the sliding vertical baffle 12 abuts against wall panel 1 (2); slide the lower limit panel 21 until the fixed vertical baffle 22 is in contact with the side of wall panel 2 (3). The wall can be lowered to the installation position by manually pulling the guy rope. The sliding vertical baffle 12 is located at the splicing position of wall panel 1 and wall panel 2, thereby controlling the width of the vertical joint. The upper corner of the wall panel can be aligned with the upper limit mechanism 10 by manually pulling.

[0053] S4. The first adjusting plate 40 pushes the second wall panel 3 to fit against the upper limit panel 11, and the second adjusting plate 60 pushes the second wall panel 3 to fit against the lower limit panel 21, thus completing the installation position correction and adjustment of the second wall panel 3.

[0054] S5. Install bolts to connect the construction wall panel 23 to the main structure 1 via point support.

[0055] S6. Loosen the first adjusting plate 40 and the second adjusting plate 60, remove the connection between the first connecting support 30, the second connecting support 50 and the main structure 1, and remove the installation device of the prefabricated external wall panel.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
