[0042] The technical solutions of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] In the description of the embodiments of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "top", "bottom", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "arrangement", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.

[0044] Referring to Figures 1-4 , the present invention provides an external wall reinforcement assembly for building structure transformation, which includes a plurality of basic guard frame sections 1, diagonal braces 2 and anchoring bases 3. First tenons 4 and first mortises 5 are respectively configured on both long sides of the basic guard frame section 1 for connecting adjacent basic guard frame sections 1 dispersed along the long direction; second tenons 6 and second mortises 7 are respectively configured on both high sides of the basic guard frame section 1 for connecting adjacent basic guard frame sections 1 dispersed along the high direction; a third mortise 8 is configured on the wide side surface of the basic guard frame section 1 for installing the diagonal brace 2; a fourth mortise 9 is configured on the anchoring base 3 for installing the lowermost basic guard frame section 1.

[0045] When constructing with the above reinforcement assembly, first determine the number of the basic guard frame sections 1 according to the size of the external wall, especially how many groups of basic guard frame sections 1 need to be configured along the length and height directions of the external wall respectively. Then fixedly place the anchoring base 3 and anchor the anchoring base 3 on the foundation ground. Install the lowermost basic guard frame section 1 on the anchoring base 3 in sequence, and connect and fix multiple basic guard frame sections 1 dispersed along the length direction of the external wall in pairs through the first tenons 4 and the first mortises 5. Then arrange the required number of basic guard frame sections 1 in the height direction in sequence and connect and fasten them through the second tenons 6 and the second mortises 7. Finally, install the diagonal brace 2 on the side of the basic guard frame section 1 away from the external wall. The top end of the diagonal brace 2 is connected to the third mortise 8, and the bottom end is connected to the foundation ground, so that the basic guard frame section 1, the diagonal brace 2 and the foundation bottom surface form a triangular stable support structure, and the other wide side of the basic guard frame section 1 abuts against the external wall to stably support the external wall.

[0046] Through the above technical solution, the basic section 1 of the protective frame, the diagonal brace 2 and the anchoring base 3 can all be made in a fixed shape. During construction, only the quantity of the above-mentioned fittings needs to be determined according to the actual size of the exterior wall, and then they can be installed at fixed points and connected and fastened to each other. 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 exterior wall supports of various sizes, but also has higher construction efficiency, and is simple to operate and not restricted by construction experience.

[0047] 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 in a cross shape. The main beam 1.1 and the secondary beam 1.2 extend in the same direction, and the main column 1.3 and the secondary column 1.4 extend in the same direction. One end of the secondary beam 1.2 is movably connected to the main beam 1.1 and can move along the longitudinal direction of the main beam 1.1. The first tenon 4 and the first mortise 5 are respectively disposed at the separated ends of the main beam 1.1 and the secondary beam 1.2. Since when the anchoring base 3 is installed, its distribution position is determined according to the basic section 1 of the protective frame after connection, and the first tenon 4 and the first mortise 5 are in a plug-in form, the above technical solution can, when installing the basic section 1 of the protective frame on the anchoring base 3, reduce the total length of the main beam 1.1 and the secondary beam 1.2 by moving the secondary beam 1.2, so that there is a certain distance between the first tenon 4 and the first mortise 5, facilitating the smooth connection of the anchoring base 3 and the basic section 1 of the protective frame, and then increasing the total length of the main beam 1.1 and the secondary beam 1.2 to make the first tenon 4 and the first mortise 5 gradually contact and connect, improving the operation convenience; the main column 1.3 and the secondary column 1.4 cooperate to improve the structural stability of a single basic section 1 of the protective frame and the connection stability of adjacent basic sections 1 of the protective frame. A fifth mortise 10 is disposed on the main beam 1.1. The fifth mortise 10 and the secondary column 1.4 are respectively located on both sides of the main beam 1.1 in the height direction for connecting adjacent basic sections 1 of the protective frame dispersed in the height direction.

[0048] To improve the adjustment accuracy and ensure the position stability of the secondary beam 1.2, in this embodiment, a movable cavity 11 is provided in the main beam 1.1. The movable cavity 11 extends along the length direction of the main beam 1.1 to one end face thereof to facilitate the insertion of the secondary beam 1.2 therein for sliding; a transmission screw 12 is rotatably connected in the movable cavity 11. The transmission screw 12 extends along the length direction of the movable cavity 11. One end of the transmission screw 12 is threadedly connected to the secondary beam 1.2, and the other end is connected to a driving handle 15 located outside the main beam 1.1 through a worm gear 13 and a worm 14 assembly. By rotating the driving handle 15, the worm gear assembly can be driven to act, and then the transmission screw 12 can be driven to rotate. Due to being limited by 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 receiving the force transmitted by the transmission screw 12, finally realizing the adjustment of the length of the end portion of the secondary beam 1.2 extending out of the main beam 1.1, and further realizing the adjustment of the total length of the main beam 1.1 and the secondary beam 1.2.

[0049] The worm and worm gear assembly includes a worm gear 13 and a worm 14. The worm gear 13 is fixedly sleeved outside 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 outside the main beam 1.1. Preferably, it extends outside the installation side of the diagonal brace 2 on the main beam 1.1 and is then connected to the driving handle 15. In this way, the diagonal brace 2 and the driving handle 15 are on the same side of the basic section 1 of the protective frame, which is convenient for installation and adjustment operations, while the other side of the basic section 1 of the protective frame is flat to abut against the outer wall surface to be supported. The configuration of the driving handle 15 can be determined according to actual needs. For example, it can be configured as a hexagonal block, which can only be turned by a wrench adapted to it, so there is no need to worry about accidental touch.

[0050] In addition, the movable cavity 11 can also be configured to include a first section 11.1 and a second section 11.2. The second section 11.2 is closer to the opening side of the movable cavity 11. The cross-sectional dimension of the first section 11.1 is larger than that of the second section 11.2. A slidable limit block 16 is configured in the first section 11.1; the limit 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; while the cross-sectional dimension of the second section 11.2 is adapted to that of the secondary beam 1.2, and its inner wall slidably abuts against the outer wall of the secondary beam 1.2 to ensure that the secondary beam 1.2 can only slide but not rotate. During the process of adjusting the position of the secondary beam 1.2, the limit 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.

[0051] 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 mortises 10 are arranged on each side of the main column 1.3 to ensure the structural stability and connection stability.

[0052] The first mortise 5 and the fifth mortise 10 have the same configuration, both of which are in the structure of a C-shaped groove. The opening direction of the first mortise 5 is horizontal, and the opening direction of the fifth mortise 10 is vertical. Bolts are passed through the two end plates of the C-shaped seat, and corresponding bolt through-holes are configured on the secondary column 1.4 and the first tenon 4 respectively. During implementation, the first tenon 4 is inserted into the first mortise 5, and then the bolt is passed through the bolt through-hole on the first tenon 4 and the end plate of the first mortise 5 and tightened. The secondary column 1.4 is inserted into the fifth mortise 10, and then the bolt is passed through the bolt through-hole on the secondary column 1.4 and the end plate of the fifth mortise 10 and tightened.

[0053] The second mortise 7 and the fourth mortise 9 have the same configuration, both of which are in the structure of a rectangular groove, and positioning grooves 7.1 are provided on at least one set of opposite side walls of the rectangular groove. The positioning grooves 7.1 extend inward from the opening side of the rectangular groove, and 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 both face the vertical direction. The second mortise 7 is located at the top end of the main column 1.3, and the second tenon 6 is located at the bottom end of the main column 1.3; a first positioning block 17 is configured laterally on the second tenon 6, and a horizontal bolt perforation is configured 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 just falls into the positioning groove 7.1, and then the bolt is passed through the bolt perforation on the first positioning block 17 and the end of the positioning groove 7.1 and tightened.

[0054] The third mortise 8 is configured on the side of the main column 1.3 and is inclined downward. A second positioning block 18 is configured outside the third mortise 8. The second positioning block 18 is located on both sides of the diagonal brace 2 and is connected to the diagonal brace 2 by bolts. During implementation, one end of the diagonal brace 2 close to the bolt perforation is inserted into the third mortise 8, and then the bolt is passed through the bolt perforation on the diagonal brace 2 and the second positioning block 18 and tightened. The length of the diagonal brace 2 can be determined according to actual needs and will not be more specifically limited here.

[0055] Anchoring nails 3.1 and detachable anchoring bolts 3.2 are configured at the bottom of the anchoring base 3. Horizontal extension plates 3.3 can be configured around the fourth mortise 9, and the anchoring bolts 3.2 are installed on the horizontal extension plates 3.3. The bottom ends of the anchoring nails 3.1 are sharp, and a plurality of anchoring bolts 3.2 are evenly dispersed outside the anchoring nails 3.1 to improve the anchoring effect.

[0056] Compared with the prior art, the beneficial effects of the present invention are as follows: The basic sections 1 of the protective frame, the diagonal braces 2 and the anchoring bases 3 in the present external wall reinforcement assembly can all be made by shaping. During construction, only the quantities of the above-mentioned fittings need to be determined according to the actual size of the external wall, and then they are fixedly installed at fixed points and connected and tightened with each other. Compared with the positioning, binding and fixing of connecting rods and support rods in the prior art, the technical solution of the present invention can not only adapt to external wall supports of various sizes, but also has higher construction efficiency, and is simple to operate and not limited by construction experience.

[0057] The above is the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements can be made without departing from the principle of the present invention, and these improvements and refinements should also be regarded as the protection scope of the present invention.
