[0039] Reference Appendix Figure 1-4 This utility model provides an external wall reinforcement component for building structure renovation, which includes several basic frame sections 1, diagonal braces 2, and anchoring bases 3. The long sides of the basic frame sections 1 are respectively provided with first tenons 4 and first mortises 5 to connect adjacent basic frame sections 1 that are dispersed along the long direction. The high sides of the basic frame sections 1 are respectively provided with second tenons 6 and second mortises 7 to connect adjacent basic frame sections 1 that are dispersed along the high direction. The wide side of the basic frame sections 1 is provided with a third mortise 8 for installing the diagonal braces 2. The anchoring base 3 is provided with a fourth mortise 9 for installing the bottommost basic frame section 1.

[0040] When constructing using the above-mentioned reinforcement components, firstly, determine the number of basic support sections 1 according to the dimensions of the exterior wall, especially how many sets of basic support sections 1 need to be constructed along the length and height of the exterior wall. Then, fix the anchor bases 3 at fixed points and anchor them to the foundation ground. Install the bottom layer of basic support sections 1 on the anchor bases 3 in sequence. Connect and fix the multiple basic support sections 1 that are distributed along the length of the exterior wall to each other through the first tenon 4 and the first mortise 5. Then, arrange the required number of basic support sections 1 in sequence along the height direction and connect and tighten them through the second tenon 6 and the second mortise 7. Finally, install diagonal braces 2 on the side of the basic support section 1 away from the exterior wall. The top of the diagonal brace 2 is connected to the third mortise 8, and the bottom is connected to the foundation ground, so that the basic support section 1, the diagonal brace 2 and the foundation bottom form a triangular stable support structure, and the width of the basic support section 1 is pressed against the exterior wall on the other side, providing stable support for the exterior wall.

[0041] With the above technical solution, the basic section 1 of the support frame, the diagonal brace 2 and the anchor base 3 can all be prefabricated. During construction, it is only necessary to determine the quantity of the above accessories according to the actual size of the exterior wall, and then install them at fixed points and connect and tighten them together. Compared with the positioning, binding and fixing of connecting rods and support rods in the existing technology, this technical solution can not only adapt to the support of exterior walls of various sizes, but also has higher construction efficiency, and is simple to operate and is not limited by construction experience.

[0042] In this embodiment, the basic section 1 of the protective frame includes a main beam 1.1, a secondary beam 1.2, a main column 1.3, and a secondary column 1.4. The main beam 1.1 and the main column 1.3 are arranged in a cross shape. The main beam 1.1 and the secondary beam 1.2 extend in the same direction, as do the main column 1.3 and the secondary column 1.4. One end of the secondary beam 1.2 is movably connected to the main beam 1.1 and can move along the length of the main beam 1.1. The first tenon 4 and the first mortise 5 are respectively located at the opposite ends of the main beam 1.1 and the secondary beam 1.2. Since the distribution position of the anchoring base 3 is determined based on the connected basic section 1 of the protective frame when it is installed, and the first tenon 4 and the first mortise 5 are in the form of a plug-in joint, the above technical solution allows the basic section 1 of the protective frame to be installed on the anchoring base 3. When moving the secondary beam 1.2, the total length of the main beam 1.1 and the secondary beam 1.2 is reduced, so that there is a certain distance between the first tenon 4 and the first mortise 5, so as to facilitate the smooth connection of the anchor base 3 and the basic section 1 of the guard frame. Then the total length of the main beam 1.1 and the secondary beam 1.2 is increased, so that the first tenon 4 and the first mortise 5 gradually contact and connect, improving the ease of operation. The main column 1.3 and the secondary column 1.4 work together to improve the structural stability of a single basic section 1 of the guard frame and the connection stability of adjacent basic sections 1 of the guard frame. The main beam 1.1 is provided with a fifth mortise 10. The fifth mortise 10 and the secondary column 1.4 are located on both sides of the height direction of the main beam 1.1, respectively, to connect adjacent basic sections 1 of the guard frame that are dispersed along the height direction.

[0043] To improve adjustment accuracy and ensure the positional stability of the secondary beam 1.2, this embodiment provides a movable cavity 11 inside the main beam 1.1. The movable cavity 11 extends along the length of the main beam 1.1 to one end face to facilitate the insertion and sliding of the secondary beam 1.2. A transmission screw 12 is rotatably connected inside the movable cavity 11. The transmission screw 12 extends along the length of the movable cavity 11. One end of the transmission screw 12 is threaded to the secondary beam 1.2, and the other end is connected to the drive handle 15 located outside the main beam 1.1 through a worm gear 13 and worm 14 assembly. By rotating the drive handle 15, the worm gear assembly can be driven to move, which in turn drives the transmission screw 12 to rotate. Due to the limitation of the inner wall of the movable cavity 11, the secondary beam 1.2 cannot rotate around the axis of the transmission screw 12, but can only move along the length direction of the movable cavity 11 after being transmitted by the transmission screw 12. This ultimately achieves the adjustment of the length of the end of the secondary beam 1.2 that extends out of the main beam 1.1, thereby achieving the adjustment of the total length of the main beam 1.1 and the secondary beam 1.2.

[0044] The worm gear assembly includes a worm gear 13 and a worm 14. The worm gear 13 is fixedly sleeved on the outside of the transmission screw 12. The worm 14 is arranged perpendicular to the transmission screw 12 and meshes with the worm gear 13. The other end of the worm 14 is rotatably connected to the main beam 1.1 and extends out of the main beam 1.1, preferably extending out of the mounting side of the diagonal brace 2 on the main beam 1.1, and then connected to the drive handle 15. In this way, the diagonal brace 2 and the drive handle 15 are located on the same side of the basic section 1 of the protective frame, which facilitates installation and adjustment. The other side of the basic section 1 of the protective frame is flat to press against the outer wall surface to be supported. The configuration of the drive handle 15 can be determined according to actual needs. For example, it can be configured as a hexagonal block, which can only be turned with a wrench that is compatible with it, so there is no need to worry about accidental activation.

[0045] Furthermore, the movable cavity 11 can be configured to include a first section 11.1 and a second section 11.2, with the second section 11.2 closer to the opening of the movable cavity 11. The cross-sectional dimensions of the first section 11.1 are larger than those of the second section 11.2. A slidable limiting block 16 is disposed within the first section 11.1. The limiting block 16 is fixedly connected to the secondary beam 1.2 and has a cross-sectional dimension larger than that of the secondary beam 1.2. The cross-sectional dimensions of the second section 11.2 are adapted to those of the secondary beam 1.2, and its inner wall slides against the outer wall of the secondary beam 1.2 to ensure that the secondary beam 1.2 can only slide and cannot rotate. During the adjustment of the position of the secondary beam 1.2, the limiting block 16 can slide with the secondary beam 1.2, but it can prevent the secondary beam 1.2 from slipping out of the movable cavity 11 and falling off.

[0046] In this embodiment, the secondary column 1.4 is located on the top surface of the main beam 1.1, the fifth mortise 10 is located on the bottom surface of the main beam 1.1, and a set of secondary columns 1.4 and a set of fifth mortise 10 are provided on each side of the main column 1.3 to ensure structural stability and connection stability.

[0047] The first mortise 5 and the fifth mortise 10 have the same configuration, both being C-shaped grooves. The opening of the first mortise 5 faces horizontally, while the opening of the fifth mortise 10 faces vertically. Bolts are installed on the two end plates of the C-shaped seat, and corresponding bolt holes are provided on the secondary post 1.4 and the first tenon 4. In practice, the first tenon 4 is inserted into the first mortise 5, and then the bolt is passed through the bolt hole on the first tenon 4 and the end plate of the first mortise 5 and tightened. The secondary post 1.4 is inserted into the fifth mortise 10, and then the bolt is passed through the bolt hole on the secondary post 1.4 and the end plate of the fifth mortise 10 and tightened.

[0048] The second mortise 7 and the fourth mortise 9 have the same configuration, both being rectangular grooves. At least one set of opposite sidewalls of the rectangular grooves are provided with positioning grooves 7.1, which extend inward from the opening side of the rectangular groove. Bolts are inserted through the two ends of the positioning grooves 7.1. The openings of the second mortise 7 and the fourth mortise 9 are both vertical. The second mortise 7 is located at the top of the main column 1.3, and the second tenon 6 is located at the bottom of the main column 1.3. A first positioning block 17 is provided on the side of the second tenon 6. A horizontal bolt hole is provided on the first positioning block 17. After the second tenon 6 is inserted into the second mortise 7 or the fourth mortise 9, the first positioning block 17 falls exactly into the positioning groove 7.1. Then, the bolt is passed through the bolt hole on the first positioning block 17 and the end of the positioning groove 7.1 and tightened.

[0049] The third mortise 8 is located on the side of the main column 1.3, sloping downwards. A second positioning block 18 is positioned outside the third mortise 8, located on both sides of the diagonal brace 2, and connected to the diagonal brace 2 by bolts. During implementation, the end of the diagonal brace 2 closest to the bolt hole is inserted into the third mortise 8, and then the bolt is passed through the bolt hole and the second positioning block 18 on the diagonal brace 2 and tightened. The length of the diagonal brace 2 can be determined according to actual needs; no further specific limitation is made here.

[0050] The bottom of the anchoring base 3 is provided with anchoring nails 3.1 and detachable anchoring bolts 3.2. A horizontal extension plate 3.3 can be constructed around the fourth mortise 9, and the anchoring bolts 3.2 are installed on the horizontal extension plate 3.3. The bottom end of the anchoring nail 3.1 is sharp, and multiple anchoring bolts 3.2 are evenly distributed on the outside of the anchoring nail 3.1 to improve the anchoring effect.

[0051] Compared with the prior art, the beneficial effects of this utility model are as follows: the basic section 1 of the protective frame, the diagonal brace 2 and the anchor base 3 in this external wall reinforcement component can all be prefabricated. During construction, it is only necessary to determine the quantity of the above accessories according to the actual size of the external wall, and then install them at fixed points and connect and tighten them together. Compared with the positioning, binding and fixing of connecting rods and support rods in the prior art, this technical solution can not only adapt to external wall support of various sizes, but also has higher construction efficiency, and is simple to operate and is not limited by construction experience.

[0052] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
