Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a gas pressure-assisted brace-free prefabricated exterior wall panel installation device and a construction method thereof. Background Art

[0002] During the installation of traditional prefabricated exterior wall panels, ensuring the stability and verticality of the exterior wall panels is a crucial link, which is not only related to the overall structural safety of the building, but also directly affects the aesthetic appearance of the building and the durability of later use. In order to achieve this goal, the method of setting diagonal braces is generally adopted during the construction process to provide necessary support for the exterior wall panels. As a temporary supporting structure, the installation of diagonal braces is usually carried out immediately after the exterior wall panels are hoisted to the predetermined position. One end of the diagonal brace is fixed to the completed building structure (such as the main frame, floor slab or installed wall), and the other end is tightly against the exterior wall panel. By adjusting the length and angle of the diagonal brace, the exterior wall panel can be kept vertical and prevented from shifting or tilting due to wind, deadweight or construction disturbance.

[0003] However, in the existing installation process of prefabricated exterior wall panels, a large number of diagonal braces need to be set up to ensure the stability and verticality of the exterior wall panels. This practice inevitably brings many inconveniences and defects to the construction site, making the on-site environment unclear and disorderly, which is specifically reflected in the following aspects: First, a large number of diagonal braces occupy valuable construction space, making the originally limited working area more crowded, which not only limits the movement and working efficiency of construction personnel, but also may increase the risk of safety accidents such as collisions or falls during construction. At the same time, the stacking and arrangement of diagonal braces also need to be carefully planned and arranged, otherwise it is easy to cause chaos on site and affect the construction progress and quality. Secondly, the installation and removal of diagonal braces are cumbersome and time-consuming. During the installation process, construction personnel need to measure, locate and fix each diagonal brace one by one to ensure that it can accurately and stably support the exterior wall panels. When removing, they need to check the fixing of the diagonal braces one by one and take appropriate methods to remove them safely. These tasks not only increase the labor intensity of construction personnel, but also extend the construction period and increase the construction cost, and there are certain defects.

[0052] In this embodiment, the reaction plate 2 is mounted on the base plate 11 via an assembly frame 21 .

[0053] See also Figure 4 and Figure 5 The assembly frame 21 includes: a humanoid frame 211, a pull rod 212, and a supporting rod 213.

[0054] There are two humanoid frames 211. The two humanoid frames 211 are arranged opposite to each other. The two humanoid frames 211 are arranged along the length direction of the base plate 11. The two humanoid frames 211 are connected to a support plate 214 on one side away from the clamping flange 12.

[0055] The pull rod 212 is detachably mounted between the two human-shaped frames 211. The bottom of the reaction plate 2 is connected with a shaft sleeve 22. The pull rod 212 is rotatably inserted into the shaft sleeve 22.

The second pressing plate 216 presses against the outside of the other human-shaped frame 211.

[0058] As a preferred embodiment, a wear-resistant pad is laid on the side of the inflation airbag 3 away from the reaction plate 2.

[0059] The present invention provides a construction method of a gas pressure-assisted brace-free prefabricated exterior wall panel installation device, comprising the following steps:

[0060] S1. Install the groove assembly 1 along the installation route of the prefabricated exterior wall panel 4, so that the guide groove between the two clamping flanges 12 of the groove assembly 1 is arranged along the length direction of the installation route.

[0061] The trough components are installed on the ground or floor.

[0062] S2. Insert the lower part of the prefabricated exterior wall panel 4 into the guide groove, and connect the two clamping flanges 12 with an anchor 13.

[0063] S3. A reaction plate 2 is set on the base plate 11 of the socket assembly. The positions of the reaction plates 2 on the two base plates 11 of the groove assembly 1 correspond to each other, and a gap is formed between the upper end of the reaction plate 2 and the prefabricated exterior wall panel 4.

[0064] S4. Install the inflation airbag 3 on the inner side of the reaction plate 2.

[0065] S5. The inflation amounts of the two inflation airbags 3 at corresponding positions are adjusted so that the inflation airbags 3 are supported on the prefabricated exterior wall panels 4, and the verticality of the prefabricated exterior wall panels 4 is adjusted so that the prefabricated exterior wall panels 4 are arranged vertically.

[0066] First, on the ground or floor, two grooved components are set in an opposing state, leaving an installation gap between them. The width of this gap is precisely designed to match the thickness of the prefabricated exterior wall panels. This design ensures that the prefabricated exterior wall panels can be accurately embedded between the two grooved components during installation to form a stable bottom support. The anchors are installed on the two grooved components. Their main function is to firmly attach the grooved components to the outside of the floor. Through the tension of the anchors, the bottom of the prefabricated exterior wall panels is effectively blocked and supported, avoiding deviation or tilting caused by an unstable bottom during installation.

[0067] In order to further enhance the stability of the support, multiple assembly frames are set on the slotted components and are evenly distributed. These assembly frames not only provide a solid foundation for subsequent installation steps, but also ensure the uniform distribution of supporting force and prevent damage caused by excessive force at a single point.

[0068] The reaction plates are installed on the assembly racks, which are perpendicular to the floor. The main function of the reaction plates is to serve as the installation base for the expansion airbags and to provide stable support for the upper part of the prefabricated exterior wall panels.

[0069] Finally, the expansion airbag is installed on the reaction plate, with one side of the airbag in contact with the prefabricated exterior wall panel. During the installation process, the expansion airbag can accurately control the verticality between the prefabricated exterior wall panel and the floor by adjusting the air pressure.

[0070] When the prefabricated exterior wall panel is found to be offset or tilted, the inflatable airbag will adjust the air pressure to generate corresponding thrust to restore the prefabricated exterior wall panel to the correct vertical position.

[0071] The air pressure-assisted brace-free prefabricated exterior wall panel installation device of the present invention realizes rapid, stable and accurate installation of prefabricated exterior wall panels, and effectively solves the problems caused by the large-scale use of braces in traditional installation methods.

[0072] In this embodiment, the horizontal and vertical surfaces of the reinforcement frame are in close contact with the horizontal and vertical surfaces of the base plate, respectively, to form a stable reinforced structure. This design not only increases the overall strength of the trough assembly, but also enables it to maintain a stable shape and position when bearing the weight of the prefabricated exterior wall panel and the external force during the installation process. Reinforcement ribs are also provided on the reinforcement frame, and the number and distribution position of the reinforcement ribs are matched with the reinforcement frame. The addition of the reinforcement ribs further enhances the structural strength of the reinforcement frame, so that the trough assembly can maintain better stability and durability in a complex and changeable installation environment. It is particularly noteworthy that the reinforcement frame on one side is also provided with concrete self-tapping bolts that penetrate the base plate and extend to the floor. These concrete self-tapping bolts not only firmly fix the reinforcement frame and the base plate to the floor, but also tightly connect the trough assembly to the building structure itself by penetrating the floor. This connection method greatly improves the fixing effect and pull-out resistance of the trough assembly, and ensures the stability and safety of the prefabricated exterior wall panel during the installation process.

[0073] In this embodiment, the humanoid frames are fixedly installed on the surface of the base plate, and the number of the humanoid frames is arranged in even numbers, with two of them forming a group. The support plate is fixedly installed between two adjacent humanoid frames.

[0074] First, the human-shaped frames are fixedly installed on the surface of the base plate, and the number of human-shaped frames is set in even numbers, with two in a group. This layout ensures the stability and uniform force of the assembly frame in the horizontal direction. The human-shaped frames, as the main load-bearing structure of the assembly frame, can withstand the weight of the prefabricated exterior wall panels and various external forces during the installation process. Then, the support plate is fixedly installed between two adjacent human-shaped frames. The addition of the support plate enhances the overall rigidity and stability of the assembly frame, making it less likely for the assembly frame to be deformed or damaged when bearing weight. At the same time, the support plate also plays the role of connecting and fixing adjacent human-shaped frames, making the entire assembly frame a stable whole. Then, the through hole serves as the installation base of the tie rod, providing stable support and positioning for the tie rod. By adjusting the position and number of the through holes, the layout and height of the tie rod can be flexibly adjusted to adapt to prefabricated exterior wall panels of different sizes and shapes.

[0075] In this embodiment, the expansion airbag is fixedly mounted on the surface of the reaction plate away from the support rod, wherein the expansion airbag is also provided with a valve core. The wear-resistant layer is fixedly mounted on the surface of the expansion airbag, wherein one surface is in contact with the prefabricated exterior wall panel.

[0076] The expansion bladders are designed to allow precise adjustment of the verticality of prefabricated cladding panels during installation.

[0077] First, the expansion airbag is fixedly mounted on the surface of the side of the reaction plate away from the support rod. This design enables the expansion airbag to directly act on the prefabricated exterior wall panel to provide it with necessary support and adjustment force. During the adjustment process, an appropriate amount of gas is filled into the expansion airbag through the valve core. The gas will gradually expand after entering the expansion airbag, thereby pushing the expansion airbag and the wear-resistant layer on its surface to expand outward. Since the wear-resistant layer is fixedly mounted on the surface of the expansion airbag and one side of the surface is in close contact with the prefabricated exterior wall panel, when the expansion airbag expands, the wear-resistant layer will serve as a direct contact surface to evenly transfer the thrust of the expansion airbag to the prefabricated exterior wall panel. The presence of the wear-resistant layer not only protects the expansion airbag from direct friction and wear on the surface of the prefabricated exterior wall panel, but also ensures the stability and reliability of the thrust transmission. By accurately controlling the inflation amount of the valve core, the expansion degree of the expansion airbag can be finely adjusted, thereby achieving precise adjustment of the verticality of the prefabricated exterior wall panel.

[0078] In this embodiment, a connection groove is processed on the side of the reaction plate, and a level bubble meter is fixedly installed in the connection groove. As a key component of the supporting structure, the reaction plate has a connection groove processed on its side end face. This design cleverly integrates the horizontal detection function. A horizontal bubble meter is fixedly installed in the connection groove. The horizontal bubble meter is firmly embedded in the connection groove through a precise manufacturing process to ensure that it will not be offset due to vibration or external force during operation. The working principle of the horizontal bubble meter is based on the natural settlement phenomenon of bubbles under the action of gravity. When the reaction plate is in a vertical state, the bubbles in the horizontal bubble meter will be located at its center position or the specified horizontal scale line, which means that the reaction plate and the prefabricated exterior wall panels connected to it are in a vertical state. On the contrary, if the bubbles deviate from the center position or the specified horizontal scale line, it means that the reaction plate or the overall structure is tilted and needs to be adjusted. During the installation of the prefabricated exterior wall panels, the construction personnel can quickly and accurately judge the vertical state of the reaction plate and the prefabricated exterior wall panels by observing the position of the bubbles in the horizontal bubble meter. Once the tilt is found, adjustment measures can be taken immediately, such as adjusting the height and position of the reaction plate or using the inflatable airbag for fine-tuning until the horizontal bubble meter displays a horizontal state.

[0079] The pneumatically assisted brace-free prefabricated exterior wall panel installation device of the present invention inflates the inflatable airbag, and uses the expansion of the inflatable airbag to push the wear-resistant layer to fine-tune the verticality of the prefabricated exterior wall panel, thereby ensuring that the verticality between the prefabricated exterior wall panel and the floor meets the requirements. In the entire workflow, the various components cooperate with each other, and through precise installation and adjustment, the prefabricated exterior wall panel is stably and accurately installed on the floor, and the traditional brace structure is not required, thereby improving the installation efficiency and safety.

[0080] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.
