[0017] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0018] Example 1 See also Figures 1 to 3 , an assembled exterior wall panel fixing structure device comprises a top beam 1, a bottom beam 2 and a prefabricated exterior wall panel 3, the top beam 1 and the bottom beam 2 are arranged in parallel in the horizontal direction, and the prefabricated exterior wall panel 3 is arranged between the top beam 1 and the bottom beam 2 in the vertical direction; it also includes a positioning device capable of positioning the prefabricated exterior wall panel 3, the positioning device comprises an L-shaped limiting plate 4 and a clamping mechanism, the L-shaped limiting plate 4 is arranged on the opposite sides of the top beam 1 and the bottom beam 2 respectively along the length direction of the top beam 1 and the bottom beam 2, the two L-shaped limiting plates 4 are symmetrically arranged with the midpoint of the connecting line of the top beam 1 and the bottom beam 2 as the center, the L-shaped limiting plate 4 is provided with a connecting mechanism 5 that can be connected to the top beam 1 and the bottom beam 2, the clamping mechanism is arranged on the opposite sides of the two L-shaped limiting plates 4, the clamping mechanism comprises a baffle 7 and a fixing plate 15, the baffle 7 is connected to the fixing plate 15, the baffle 7 and the fixing plate 15 are in a right angle relationship, and the fixing plate 15 is connected to the L-shaped limiting plate 4.

[0019] The connecting mechanism 5 includes a through hole 51 and a fastening bolt 53. The through holes 51 are arranged in an array on the L-shaped limiting plate 4. The top beam 1 and the bottom beam 2 are provided with threaded holes corresponding to the through holes 51 in an array. The fastening bolt 53 passes through the through hole 51 and is threadedly connected to the threaded holes of the top beam 1 and the bottom beam 2.

[0020] The through hole 51 on the L-shaped limiting plate 4 is provided with a receiving groove 52 for receiving the bolt head, and the diameter of the receiving groove 52 is larger than the diameter of the through hole 51 .

[0021] The baffle plate 7 is provided with a groove 9, in which a pressure block 10 is slidably connected, and a clamping bolt 12 is threadedly connected to the baffle plate 7, and the pressure block 10 is rotatably connected to the clamping bolt 12.

[0022] A rubber pad 11 is provided on the pressing block 10 .

[0023] A right-angle plate 8 is connected between the baffle plate 7 and the fixing plate 15 .

[0024] The fixing bolts 13 connecting the fixing plate 15 and the L-shaped limiting plate 4 are provided with washers 14 for increasing the friction between the fixing bolts 13 and the L-shaped limiting plate 4 .

[0025] The fixing plate 15 is threadedly connected with a fixing bolt 13 , and the L-shaped limiting plate 4 is provided with a thread groove 6 in an array. The fixing plate 15 is connected to the L-shaped limiting plate 4 through the threaded transmission connection between the fixing bolt 13 and the thread groove 6 .

[0026] Principle and operation process The clamping mechanism in the present invention is composed of a baffle plate 7 and a fixing plate 15, which are connected at right angles. During the entire installation process, the prefabricated exterior wall panel 3 can be fixed without drilling holes. The installation of traditional prefabricated exterior wall panels 3 requires drilling holes in the panels, which not only destroys the structural integrity of the prefabricated exterior wall panels 3 themselves, but also requires high position and precision of the holes, and the operation is complicated. The clamping mechanism of the present device cooperates with the L-shaped limiting plate 4 to apply stable pressure to the prefabricated exterior wall panel 3 from the outside to achieve fixation. The fixing plate 15 is connected to the L-shaped limiting plate 4 to provide a support point for the entire clamping mechanism, while the baffle plate 7 directly contacts the prefabricated exterior wall panel 3. In this way, the prefabricated exterior wall panel 3 is firmly positioned between the top beam 1 and the bottom beam 2.

[0027] The baffle plate 7 is provided with a groove 9, in which a pressing block 10 is slidably connected, and a threaded transmission connection is made on the baffle plate 7 to abut against a bolt 12, and the pressing block 10 is rotationally connected to the abutting bolt 12. During the installation process, when the baffle plate 7 cannot directly and effectively abut against the prefabricated exterior wall panel 3, the abutting bolt 12 is rotated, and due to the threaded transmission relationship between the abutting bolt 12 and the baffle plate 7, the abutting bolt 12 will move along its axial direction during the rotation process. Because the pressing block 10 is rotationally connected to the abutting bolt 12, the axial movement of the abutting bolt 12 will push the pressing block 10 to slide in the groove 9 of the baffle plate 7. During the sliding process, the pressing block 10 can accurately fill the gap between the baffle plate 7 and the prefabricated exterior wall panel 3, so that the pressing block 10 is tightly against the prefabricated exterior wall panel 3, thereby applying uniform pressure to the prefabricated exterior wall panel 3, ensuring that the prefabricated exterior wall panel 3 will not be displaced due to external force after installation, and effectively improving the reliability of the installation.

[0028] A rubber pad 11 is provided on the pressing block 10 to protect the prefabricated exterior wall panel 3 from damage during the pressing process. In the production process of the prefabricated exterior wall panel 3, there may be a situation where the granular concrete is not completely removed, and these residual particles will form tiny protrusions on the surface of the prefabricated exterior wall panel 3. When the pressing block 10 presses the prefabricated exterior wall panel 3, if there is no buffering measure, the rigid contact between the pressing block 10 and the prefabricated exterior wall panel 3 will cause these protrusions to exert a large pressure on the surface of the prefabricated exterior wall panel 3, which may cause scratches or local damage to the surface of the prefabricated exterior wall panel 3. The rubber pad 11 has good elasticity and buffering properties. When the pressing block 10 contacts the prefabricated exterior wall panel 3, the rubber pad 11 can form a buffer layer between the two to absorb and disperse the pressure, avoid damage to the prefabricated exterior wall panel 3 due to excessive local pressure, and ensure the integrity and quality of the prefabricated exterior wall panel 3.

[0029] The L-shaped limiting plate 4 is provided with a receiving groove 52 at the through hole 51, and the diameter of the receiving groove 52 is larger than the diameter of the through hole 51. When installing the L-shaped limiting plate 4, it is necessary to use a fastening bolt 53 to pass through the through hole 51 and connect with the threaded hole on the top beam 1 or the bottom beam 2. Due to the existence of the receiving groove 52, the bolt head of the fastening bolt 53 can be accommodated therein. If there is no receiving groove 52, the bolt head will protrude from the side of the L-shaped limiting plate 4 close to the top beam 1 or the bottom beam 2. When installing the prefabricated exterior wall panel 3, this protrusion may collide with the prefabricated exterior wall panel 3, resulting in the prefabricated exterior wall panel 3 being unable to be smoothly installed in place, or uneven force due to contact with the protruding part after installation, affecting the stability of the overall structure. The design of the receiving groove 52 effectively avoids these problems, ensuring that the prefabricated exterior wall panel 3 can be tightly matched with the top beam 1, the bottom beam 2 and the L-shaped limiting plate 4 without hindrance.

[0030] A washer 14 is provided on the fixing bolt 13 connecting the fixing plate 15 and the L-shaped limiting plate 4. During the use of the entire device, it will be affected by various factors, and these factors will exert a force on the fixing bolt 13. The presence of the washer 14 increases the contact area between the fixing bolt 13 and the L-shaped limiting plate 4. Under the condition that the positive pressure remains unchanged, the increase in the contact area can increase the friction force. Therefore, the washer 14 can effectively increase the friction force between the fixing bolt 13 and the L-shaped limiting plate 4, prevent the fixing bolt 13 from loosening or falling off when subjected to external force, ensure the stability of the connection between the fixing plate 15 and the L-shaped limiting plate 4, and further ensure the safety of the fixing structure of the entire prefabricated exterior wall panel 3.

[0031] The triangle plate is arranged between the baffle plate 7 and the fixing plate 15, and the stability principle of the triangle is utilized. When the prefabricated exterior wall panel 3 is installed, the weight of the prefabricated exterior wall panel 3 and the external force that may be applied to the prefabricated exterior wall panel 3 will exert pressure on the baffle plate 7. The triangle is one of the most stable shapes among geometric figures, and the triangle plate decomposes the force applied to the baffle plate 7 and transmits it to the fixing plate 15. In this way, the triangle plate enhances the resistance of the baffle plate 7 when subjected to external force, so that the baffle plate 7 can remain stable during long-term use, better support the prefabricated exterior wall panel 3, and prevent the prefabricated exterior wall panel 3 from being unstable due to deformation or displacement of the baffle plate 7.

[0032] When in use, first place the L-shaped limit plates 4 on the opposite sides of the top beam 1 and the bottom beam 2, respectively, so that the two L-shaped limit plates 4 are symmetrical with the midpoint of the line connecting the top beam 1 and the bottom beam 2 as the center. Then, pass the fastening bolts 53 through the through holes 51 on the L-shaped limit plates 4. Since the top beam 1 and the bottom beam 2 are arrayed with threaded holes corresponding to the through holes 51, the L-shaped limit plates 4 are tightly connected to the top beam 1 and the bottom beam 2 by rotating the fastening bolts 53. In this process, pay attention to the receiving grooves 52 at the through holes 51 on the L-shaped limit plates 4 to ensure that the bolt heads can be fully accommodated therein to avoid affecting the subsequent installation of the prefabricated exterior wall panels 3. Then place the prefabricated exterior wall panels 3 between the two L-shaped limit plates 4 and press against the protruding side of the L-shaped limit plates 4. Then connect the fixing plate 15 to the L-shaped limit plates 4 through the fixing bolts 13. During operation, align the fixing bolts 13 on the fixing plate 15 with the thread grooves 6 arranged in an array on the L-shaped limiting plate 4, and then rotate the fixing bolts 13 to make them threadedly connected with the thread grooves 6. Install washers 14 on the fixing bolts 13 to increase friction and prevent the fixing bolts 13 from loosening and falling off. During installation, it is necessary to ensure that the baffle 7 is on the side close to the prefabricated exterior wall panel 3.

[0033] If the baffle 7 can directly press against the prefabricated exterior wall panel 3, the baffle 7 can be directly used to preliminarily position and support the prefabricated exterior wall panel 3. If the baffle 7 cannot directly press against the prefabricated exterior wall panel 3, the pressing bolt 12 is rotated to make the pressing bolt 12 push the pressing block 10 to slide in the groove 9 of the baffle 7 until the rubber pad 11 on the pressing block 10 is in close contact with the prefabricated exterior wall panel 3 and applies appropriate pressure, thereby completing the pressing operation of the prefabricated exterior wall panel 3. In this process, the rubber pad 11 plays a role of buffer protection to prevent damage to the prefabricated exterior wall panel 3. Through the above steps, the fixed installation of the assembled exterior wall panel is completed.

[0034] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
