[0031] The reinforcement structure 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings. The reinforcement structure 100 is used for reinforcing a building 200 .

[0032] Reference Figure 1-Figure 4 As shown, the reinforcement structure 100 according to the embodiment of the present invention may include: reinforcing ribs 10 , grouting material 20 and structural columns 30 .

[0033] Specifically, one end of the reinforcing bar 10 is used to extend from the outside of the building 200 into the hole 220 opened in the inner wall, and one end of the reinforcing bar 10 extends downward along the length direction of the inner wall, and the other end of the reinforcing bar 10 is located outside the building 200. The grouting material 20 is poured into the hole 220, and the structural column 30 is arranged outside the building 200 and wraps the other end of the reinforcing bar 10. The other end of the reinforcing bar 10 is bent and anchored to the edge of the structural column 30 away from the inner wall.

[0034] The reinforcing rib 10 may be HRB400 threaded steel bar, etc. The reinforcing rib 10 may be one or more, for example, a plurality of reinforcing ribs 10 may be used to reinforce a plurality of inner walls in the building 200. The building 200 may be a residence such as a villa, a unit building in a community, etc.

[0035] The walls in the building 200 can be divided into two categories, namely, exterior walls and interior walls, according to their positions and directions in the building 200. The walls arranged along the edges of the building 200 are called exterior walls, the outer surfaces of the exterior walls form the outer wall surfaces of the building 200, and the walls surrounded by the exterior walls are called interior walls. The length direction of the interior wall can be the extension direction of the larger part of the interior wall in the horizontal direction, that is, at least one end of the length direction of the interior wall is connected to the exterior wall.

[0036] For example, in some specific embodiments, Figure 1 As shown, the inner wall includes an inner transverse wall 210 and the inner transverse wall 210 is the main load-bearing wall. The inner transverse wall 210 carries a relatively large load, and the length direction of the inner transverse wall 210 is the front-to-back direction shown in the figure.

[0037] The load may include the weight of the buildings contained in the building 200, the weight of the furniture in the building 200, etc. For example, the load imposed by the upper floor of the building 200 on the lower floor includes the weight of the walls of the upper floor, the weight of the furniture in the upper floor, etc.

[0038] The hole 220 can be opened by drilling equipment. The grouting material 20 can be a high-strength grouting material, etc., which is convenient for filling the hole 220 to connect the reinforcing bar 10 and the inner wall of the hole 220.

[0039] The structural column 30 may be a concrete column made of ordinary concrete, etc., which has high compressive strength, low price and good economy. The structural column 30 may be a whole or include multiple parts. For example, in some embodiments, there are multiple reinforcing ribs 10 and they are used to reinforce the inner transverse walls 210 of different floors. The reinforcing ribs 10 of different floors are arranged in the up-down direction. The structural column 30 may be a column extending continuously in the up-down direction to wrap different reinforcing ribs 10 at the same time. The structural column 30 may also include multiple separate block parts to respectively wrap the other ends of different reinforcing ribs 10.

[0040] One end of the reinforcing rib 10 extends downwardly along the length direction of the inner wall so that the reinforcing rib 10 is inserted into the hole 220 downwardly. Figure 2-Figure 3 As shown, the right end of the left reinforcing rib 10 is inserted into the hole 220 at an angle toward the lower right, and the left end of the right reinforcing rib 10 is inserted into the hole 220 at an angle toward the lower left.

[0041] The reinforcing rib 10 is inserted into the hole 220 at an angle downward, so that the load received by the inner wall can be transferred to the reinforcing rib 10 and the reinforcing rib 10 is pulled, and the other end of the reinforcing rib 10 is bent and anchored to the edge of the structural column 30 away from the inner wall, that is, the other end of the reinforcing rib 10 is located outside the structural column 30 and inside the structural column 30, so that the other end of the reinforcing rib 10 is tightly connected to the structural column 30. The load of the inner wall is transferred to the structural column 30 through the reinforcing rib 10, so that part of the vertical load received by the inner wall is transferred to the structural column 30, so that the inner wall can bear a greater load, thereby increasing the compressive resistance of the building 200 and realizing the compressive reinforcement of the building 200.

[0042] In some embodiments, the obliquely placed reinforcing ribs 10 passing through the “X”-shaped shear cracks of the wall can also improve the earthquake resistance of the building 200 .

[0043] In some related technologies, traditional cement mortar surface layer or reinforced concrete surface layer is used to construct on both sides of the wall to strengthen the building. It is necessary to enter the private living area of ​​the residents for construction, which causes great disturbance and easily damages the original structure such as the decoration and furniture arrangement inside the building, affecting the normal use of the building by the residents after construction. In addition, the surface layer is thick, which occupies the indoor use space of the building, resulting in low satisfaction of residents. Construction on both sides of the wall requires a long construction period and low construction efficiency.

[0044] The present application achieves the function of compressive reinforcement of the building 200 by extending the reinforcing ribs 10 into the holes 220 on the inner wall of the building 200. This not only allows construction without entering the house and reduces construction disturbance, but also is not easy to damage the original structure such as the decoration and furniture arrangement inside the building 200, which is conducive to the normal use of the building 200 by the residents after construction. There is no need to use a thicker surface layer to construct on both sides of the wall along the thickness direction, that is, there is no need to occupy the indoor use space of the original building 200, it is not easy to reduce the living area of ​​the residents, the residents are more satisfied, and it is conducive to shortening the construction period and improving construction efficiency.

[0045] According to the reinforcement structure 100 of the embodiment of the present invention, the reinforcement function of the building 200 can be realized through the grouting material 20, the structural column 30 and the reinforcing ribs 10 arranged obliquely downward, and the construction can be carried out without entering the house, and the construction disturbance is small, which is conducive to the normal use of the decoration and furniture in the original building 200 by the residents after the construction is completed. At the same time, there is no need to occupy the indoor use space of the original building 200, and the residents' satisfaction is high.

[0046] The location of the reinforcement structure 100 is not limited, and the reinforcement structure 100 can be set at the inner wall where reinforcement is required, and the specific location can be determined according to design requirements. For example, in some embodiments, Figure 1 As shown, six internal transverse walls 210 are shown in the figure, two of which have compression reinforcement requirements, and reinforcement structures 100 are set at these two internal transverse walls 210.

[0047] In some embodiments of the present invention, Figure 2-Figure 3As shown, the angle α between the extension direction of one end of the reinforcing rib 10 located in the hole 220 and the horizontal direction is 30° to 60°. If the angle α is too large, it is easy to cause the reinforcing rib 10 to tend to be arranged vertically, and the size of the inner wall in contact with the reinforcing rib 10 along its own length direction is small, resulting in the size of the inner wall that can be reinforced by the reinforced structure 100 being too small, and the reinforcement effect on the building 200 is poor. If the angle α is too small, it is easy to cause the reinforcing rib 10 to tend to be arranged horizontally, making the reinforcing rib 10 not easily deformed by tension, and the load transferred from the inner wall to the reinforcing rib 10 is small, and then the load transferred to the structural column 30 is small, and the reinforcement effect on the building 200 is poor. Making 30°≤α≤60° is conducive to improving the reinforcement effect of the reinforced structure 100 on the building 200. For example, α is 30°, 45°, 60°, etc.

[0048] In some embodiments of the present invention, Figure 2 As shown, in the longitudinal direction of the inner wall, the distance D1 between the end of the reinforcing rib 10 located in the hole 220 and the door and window 230 on the inner wall is 100-200 mm. The door and window 230 here refers to the hole in the inner wall where a door, window or other structure is installed, such as Figure 1 The structure indicated by reference numeral 230, Figure 1 There are many doors and windows 230 in the middle and they are not marked one by one.

[0049] If the spacing D1 is too large, the size of the inner wall in contact with the reinforcing rib 10 along its length direction will be small, resulting in poor reinforcement effect of the reinforcement structure 100 on the building 200. If the spacing D1 is too small, it is easy for the reinforcing rib 10 to interfere with the door or window installed at the door and window 230, resulting in problems such as looseness of the door or window. Making 100mm≤D1≤200mm is conducive to improving the reinforcement effect of the building 200 and the installation stability of the door and window 230. For example, D1 is 100mm, 150mm, 200mm, etc.

[0050] In some embodiments of the present invention, Figure 3-Figure 4 As shown, in the length direction of the inner wall, two reinforcing ribs 10 are arranged opposite to each other, and the distance D2 between the two reinforcing ribs 10 is 100-200 mm. Arranging two reinforcing ribs 10 along the length direction of the inner wall at the same inner wall is conducive to increasing the inner wall area contacted by each reinforcing rib 10 along the length direction of the inner wall, and making the downward inclination angle of the reinforcing rib 10 more suitable, so that the reinforcing rib 10 is easy to be tensilely deformed to increase the load transferred from the inner wall to the reinforcing rib 10, and then more vertical loads of the inner wall are transferred through the structural column 30, which is conducive to improving the reinforcement effect of the building 200.

[0051] If the spacing D2 is too large, the inner wall area that the reinforcing ribs 10 contact along the inner wall length direction is too small, and the reinforcement effect on the building 200 is poor. If the spacing D2 is too small, it is easy to cause position interference such as collision between two reinforcing ribs 10 at the same inner wall. Making 100mm≤D2≤200mm is conducive to improving the reinforcement effect of the building 200 and facilitating the installation of two reinforcing ribs 10 at the same inner wall. For example, D2 is 100mm, 150mm, 200mm, etc.

[0052] In some embodiments of the present invention, Figure 2-Figure 3 As shown, the diameter of the reinforcing rib 10 is 20-30 mm, and the outer diameter of the grouting material 20 is 40-60 mm, that is, the inner diameter of the hole 220 is 40-60 mm. If the diameter of the reinforcing rib 10 is too small, the strength of the reinforcing rib 10 will be too low, the tensile force that the reinforcing rib 10 can bear will be too small, and the reinforcing rib 10 will even be easily damaged. If the diameter of the reinforcing rib 10 is too large, it will be difficult to put the reinforcing rib 10 into the hole 220 and to pour the grouting material 20, which will make installation inconvenient. If the inner diameter of the hole 220 is too small, it will be difficult to open the hole 220 through the drilling equipment, and it will be inconvenient to put the reinforcing rib 10 into the hole 220 and to pour the grouting material 20. If the inner diameter of the hole 220 is too large, it will be easy to damage the wall.

[0053] The diameter of the reinforcing rib 10 is 20-30 mm, and the outer diameter of the grouting material 20 is 40-60 mm, which is conducive to improving the strength of the reinforcing rib 10, and is convenient for placing the reinforcing rib 10 into the hole 220, and is convenient for pouring the grouting material 20, which is convenient for installation, and is not easy to damage the wall, which is conducive to protecting the wall and has a good reinforcement effect on the building 200. For example, the diameter of the reinforcing rib 10 is 20 mm, 25 mm, 30 mm, etc., and the outer diameter of the grouting material 20 is 40 mm, 50 mm, 60 mm, etc.

[0054] In some embodiments of the present invention, Figure 1 As shown, the reinforcement structure 100 includes a composite surface layer structure 40, the tensile strength standard value of the composite surface layer structure 40 is greater than or equal to 3.0Mpa and the ultimate tensile elongation is greater than or equal to 0.1%, and the composite surface layer structure 40 covers the outer surface of the building 200, covers the inner surface of the public area of ​​the building 200, or covers the outer surface of the building 200 and the inner surface of the public area of ​​the building 200. The outer surface of the building 200 includes the outer wall surface of the outer wall, and the public area of ​​the building 200 may include a stairwell 240, etc. The composite surface layer structure 40 may be high ductility concrete, etc., and the composite surface layer structure 40 may be directly purchased or prepared by itself.

[0055] The standard value of tensile strength refers to the tensile strength value measured under standard test conditions, which is a measure of the maximum stress value that a material can withstand when subjected to tension. The ultimate tensile elongation refers to the maximum strain value that a material can withstand during the stretching process, also known as uniform elongation, which is the maximum deformation of a material before plastic instability (i.e. before necking occurs).

[0056] The standard value of the tensile strength of the composite surface structure 40 is greater than or equal to 3.0Mpa and the ultimate tensile elongation is greater than or equal to 0.1%, so that the composite surface structure 40 has a relatively high tensile strength and tensile elongation. The composite surface structure 40 is covered on the outer surface of the building 200, the inner surface of the public area of ​​the building 200, or the outer surface of the building 200 and the inner surface of the public area of ​​the building 200, which can improve the seismic bearing capacity of the building 200, realize the unilateral reinforcement of the building 200, achieve non-entry construction, and do not construct on the outer surface of the building 200, which will not occupy the indoor use space of the building 200, and the residents' satisfaction is high. It should be noted here that the construction in the public area does not belong to the construction in the house, that is, covering the surface of the public area of ​​the building 200 with the composite surface structure 40 is non-entry construction.

[0057] In some related technologies, the seismic bearing capacity of a building needs to be improved by tying a steel bar structure, which has low construction efficiency. However, the present application uses a composite surface layer structure 40 to cover the outer surface of the building 200, the inner surface of the public area of ​​the building 200, or the outer surface of the building 200 and the inner surface of the public area of ​​the building 200, so that the seismic bearing capacity of the building 200 can be improved without tying a steel bar structure, and the construction efficiency is high.

[0058] In some embodiments, the composite surface layer structure 40 is partially embedded in the building 200, and the embedding depth is 10-15 mm. If the embedding depth is too large, it is easy to damage the wall. If the embedding depth is too small, the contact area between the composite surface layer structure 40 and the building 200 is too small, and the effect of improving the seismic bearing capacity of the building 200 is poor. The embedding depth is 10-15 mm, which is conducive to protecting the wall and improving the seismic bearing capacity of the building 200. For example, the embedding depth is 10 mm, 12 mm, 15 mm, etc.

[0059] For example, in some embodiments, the building 200 includes a brick masonry wall, and a horizontal mortar joint buckle treatment is performed on the reinforced side of the brick masonry wall, and the buckle depth is 10 to 15 mm.

[0060] like Figure 5 As shown, the reinforcement method of the building 200 according to the embodiment of the present invention is characterized in that the reinforcement structure 100 according to the embodiment of the present invention is adopted, and the reinforcement method includes:

[0061] S1: A hole 220 is opened in the building 200 . The hole 220 forms an opening on the outer surface of the building 200 , and the hole 220 is inclined downward along the length direction of the inner wall of the building 200 .

[0062] The hole 220 may be opened by mechanically drilling the building 200 from outside the building 200 using a drilling device.

[0063] S2: Put one end of the reinforcing rib 10 into the hole 220 through the opening, and make the other end of the reinforcing rib 10 outside the hole 220, and perform a bending and anchoring operation on the other end of the reinforcing rib 10.

[0064] S3: injecting grouting material 20 into the hole 220 to connect the reinforcing rib 10 and the inner wall of the hole 220 .

[0065] S4: A structural column 30 is manufactured outside the building 200, so that the structural column 30 is connected to the outer surface of the building 200 and wraps the other end of the reinforcing rib 10, so that the other end of the reinforcing rib is bent and anchored to the edge of one side of the structural column 30 away from the inner wall.

[0066] The structural column 30 may be a concrete column, and a concrete column is cast outside the building 200 to obtain the structural column 30. The structural column 30 is manufactured to wrap the other end of the reinforcing rib 10, so that the other end of the reinforcing rib 10 is bent and anchored to the outer edge of the structural column 30, which is conducive to the structural column 30 holding the reinforcing rib 10, and the reinforced structure 100 has a better effect of compressive reinforcement on the building 200.

[0067] The reinforcement method according to the embodiment of the present invention adopts the reinforcement structure 100 according to the embodiment of the present invention. Since the reinforcement structure 100 according to the embodiment of the present invention has the above-mentioned beneficial technical effects, the reinforcement direction according to the embodiment of the present invention can realize the reinforcement function of the building 200 through the grouting material 20, the structural column 30 and the reinforcing ribs 10 arranged obliquely downward, and can achieve the construction without entering the house, with less construction disturbance, which is conducive to the normal use of the decoration and furniture in the original building 200 by the residents after the construction is completed, and at the same time, there is no need to occupy the indoor use space of the original building 200, and the residents are more satisfied.

[0068] In some embodiments, the reinforcement method also includes: covering the outer surface of the building 200 and the inner surface of the public area of ​​the building 200 with a composite surface structure 40 to perform unilateral reinforcement on the building 200, thereby improving the earthquake resistance of the building 200 while achieving construction without entering the house, and having a better reinforcement effect on the building 200.

[0069] In some embodiments, the reinforcement method further includes: opening holes 220 on each floor of the building 200, and setting corresponding reinforcing bars 10 and grouting materials 20, and the structural columns 30 wrap the other ends of the reinforcing bars 10 corresponding to multiple floors.

[0070] By providing a reinforcement structure 100 on each floor of the building 200, the compressive strength of each floor can be improved, thereby improving the compressive strength of the entire building 200, thereby meeting the reinforcement needs of residents on more floors.

[0071] In some embodiments, Figure 1-Figure 3 As shown, the reinforcement method further includes: opening holes 220 on two opposite sides of the same floor of the building 200, and providing corresponding reinforcing ribs 10, grouting materials 20 and structural columns 30.

[0072] A plurality of reinforcing ribs 10 can be arranged on the same floor, which is beneficial to improving the compressive strength of the same floor to meet the user's higher reinforcement requirements.

[0073] A reinforcement structure 100 according to a specific embodiment of the present invention is described in detail below with reference to the accompanying drawings. It should be understood that the following description is only an exemplary illustration and cannot be construed as limiting the present invention.

[0074] like Figure 1-Figure 4 As shown, a reinforcement structure 100 according to a specific embodiment of the present invention is used for reinforcing a building 200 . The reinforcement structure 100 includes reinforcing ribs 10 , grouting material 20 , structural columns 30 and a composite surface structure 40 .

[0075] The reinforcing bar 10 is HRB400 threaded steel bar, the grouting material 20 is high-strength grouting material, the structural column 30 is a concrete column made of ordinary concrete, and the composite surface layer structure 40 is high-ductility concrete.

[0076] During the reinforcement process of the building 200, a hole 220 is firstly opened obliquely downwardly along the length direction of the wall to be reinforced, such as the inner transverse wall 210, and one end of the reinforcing bar 10 is extended obliquely downwardly from the outside of the building 200 into the hole 220. The other end of the reinforcing bar 10 is located outside the hole 220, and the other end of the reinforcing bar 10 is bent and anchored so that the other end of the reinforcing bar 10 extends downward.

[0077] Then, the grouting material 20 is poured into the hole 220 to fill the gap between the reinforcing bar 10 and the hole 220 , so that the reinforcing bar 10 is firmly installed on the inner transverse wall 210 .

[0078] Next, the structural column 30 is cast outside the hole 220 so that the structural column 30 wraps the other end of the reinforcing rib 10 , and the other end of the reinforcing rib 10 is anchored to the structural column 30 .

[0079] Furthermore, the composite surface structure 40 is pressed and applied on the outer surface of the outer wall of the building 200 and the inner surface of the wall of the stairwell 240 .

[0080] By using the reinforcement structure 100 of the present application to reinforce the building 200, the load on the reinforced inner transverse wall 210 is transferred to the reinforcing ribs 10, and the load is transferred to the structural column 30 through the reinforcing ribs 10 anchored to the structural column 30. Therefore, part of the vertical load on the inner transverse wall 210 can be transferred to the structural column 30 outside the inner transverse wall 210, reducing the load on the inner transverse wall 210, improving the compressive resistance of the inner transverse wall 210, and achieving the effect of compressive reinforcement.

[0081] Furthermore, by applying the composite surface structure 40 on the wall surface of the building 200 , the earthquake-resistant bearing capacity of the overall structure of the building 200 can be improved, thus achieving the effect of earthquake-resistant reinforcement.

[0082] The reinforcement structure 100 of the present application can effectively avoid construction work inside the house while meeting the compression and earthquake-resistant reinforcement requirements of the building 200, and provide a better experience for residents.

[0083] Other structures and operations of the reinforcement structure 100 and the reinforcement method of the building 200 according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail here.
