Description

Technical Field

[0001] This invention relates to the field of building technology, and in particular to a prefabricated building reinforcement structure and its assembly method. Background Technology

[0002] Building reinforcement is a branch of civil engineering construction. Every year in my country, a large number of buildings require technological upgrades and additional floors due to changes in production scale and processes, necessitating structural reinforcement due to overloading. Simultaneously, with the increasing demands and changes in seismic resistance requirements and fortification standards, existing buildings in many areas cannot meet the new seismic requirements, thus necessitating seismic reinforcement. For existing building beam and column structures, newly added load-bearing components must be well-connected to the original components to meet the functional and load-bearing capacity requirements after the upgrade. Otherwise, if the load-bearing performance does not meet the requirements, the safety performance of the building will be difficult to guarantee, and may even cause significant loss of life and property.

[0003] In the current engineering construction process, the actual development and construction schedule requirements are becoming increasingly tight. Structural modifications must avoid creating safety hazards, while also meeting the needs of construction period and cost savings. This has become an urgent technical problem to be solved, and it is necessary to improve the technology.

[0004] Chinese Patent Publication No. CN112761374B discloses a prefabricated building reinforcement structure and its assembly method. This structure includes a set of pre-embedded components at the connection between structural walls and structural beams. Each pre-embedded component has a plurality of barbed fixing bolts on its back, which are embedded within the structural walls and beams. Each pre-embedded component has a hinged structural rod that can be flipped and unfolded on its front. A plurality of structural stems are hinged between the structural rods and the pre-embedded components. A shell is fixed between the pre-embedded components by bolt assemblies. Concrete is injected into the shell, and the concrete and metal shell reinforce the connection between the structural walls and beams. The concrete encapsulation of the structural rods and stems enhances the strength of the concrete structure within the shell. Therefore, while the invention reinforces the building, it cannot guarantee that all components fit tightly in their corresponding positions, posing a safety hazard. Summary of the Invention

[0005] Therefore, the present invention provides a prefabricated building reinforcement structure to overcome the problem in the prior art that the reinforcement structure has low reinforcement efficiency for buildings because the corresponding components cannot be fixed in the corresponding positions when installing the prefabricated building reinforcement structure.

[0006] On one hand, the present invention provides a prefabricated building reinforcement structure, comprising:

[0007] The first support member has first connecting ears on both sides, and each connecting ear has a first connecting hole; the first support member also has a plurality of vertically arranged first through holes; the end of the first support member also has a first fixing hole.

[0008] The second support member has second connecting ears on both sides, and each connecting ear has a second connecting hole; the second support member also has several horizontally arranged second through holes; the end of the second support member also has a second fixing hole.

[0009] A plurality of first bolts, each first bolt being used to fix the first support member to a corresponding position on the structural wall through a corresponding first through hole; the number of first bolts is the same as the number of first through holes;

[0010] A plurality of second bolts, each second bolt being used to fix the second support member to a corresponding position on the structural beam by passing through a corresponding second through hole; the number of second bolts is the same as the number of second through holes.

[0011] A plurality of connecting bolts, each connecting bolt being used to pass through the corresponding first connecting hole and the second connecting hole and to be engaged with the connecting nut corresponding to the connecting bolt to fix the first support member and the second support member relative to each other;

[0012] A reinforcing member is disposed between the first support member and the second support member to form a triangular structure with the first support member and the second support member; both ends of the reinforcing member are provided with through holes.

[0013] The first fixing bolt is used to fix one end of the first support member and the reinforcement member in the corresponding position through the corresponding through hole;

[0014] The second fixing bolt is used to fix the other end of the second support and the reinforcement in the corresponding position through the corresponding through hole.

[0015] On the other hand, the present invention also provides an assembly method for a prefabricated building reinforcement structure, characterized in that it includes:

[0016] Step s1: Pre-drill holes in the structural wall and fix the first support member with several first bolts. During the process of tightening the first support member, the central control processor adjusts the pre-tightening force of the corresponding first bolt on the first support member to the corresponding value according to the angle between the first support member and the structural wall, and adjusts the pre-tightening force of each first bolt to the corresponding value according to the gap size between the first support member and the structural wall.

[0017] Step s2: Pre-drill holes in the structural beam and fix the second support member with several second bolts. During the process of tightening the second support member, the central control processor adjusts the preload of the corresponding second bolt on the second support member to the corresponding value according to the angle between the second support member and the structural beam, and adjusts the preload of each second bolt to the corresponding value according to the gap size between the second support member and the structural beam wall.

[0018] Step s3: Pass the connecting bolt through the first connecting lug on the first support member and the second connecting lug on the second support member in sequence, and use the connecting nut to clamp the first connecting lug and the second connecting lug to fix the first support member and the second support member relatively; The central control processor determines whether to adjust the preload of the connecting bolt to the corresponding value based on the included angle between the first support member and the second support member;

[0019] Step s4: Place the reinforcement component at the corresponding position between the first support and the second support. Pass the first fixing bolt through the first fixing hole in the first support and one end of the reinforcement component in sequence, and pass the second fixing bolt through the second fixing hole in the second support and the other end of the reinforcement component in sequence. Use the first fixing nut to cooperate with the first fixing bolt and the second fixing nut to cooperate with the second fixing bolt to fix the reinforcement component at the corresponding position between the first support and the second support to complete the installation of the reinforcement component.

[0020] Furthermore, during the process of tightening the first support member, the central control processor controls the angle detector to detect the angle θa between the first support member and the structural wall, and determines whether to adjust the preload F of the corresponding first bolt based on θa. The first support member is fixed to the corresponding position on the structural wall by four vertically arranged first bolts. The central control processor has a first preset angle θa1, a second preset angle θa2, a first preset preload adjustment coefficient α1, and a second preset preload adjustment coefficient α2, wherein θa1 < θa2, 1 < α1 < α2 < 1.3.

[0021] If θa≤θa1, the central control processor determines that the angle between the first support member and the structural wall meets the standard, and the central control processor controls the distance detector to detect the gap between the first support member and the structural wall to determine whether to adjust the initial preload of each of the first bolts;

[0022] If θa1<θa≤θa2, the central control processor uses α1 to adjust the preload of the corresponding first bolt set on the first support member;

[0023] If θa > θa2, the central control processor uses α2 to adjust the preload of the corresponding first bolt set on the first support member;

[0024] When the central control processor uses αi to adjust the preload F of each of the first bolts, i = 1, 2, the adjusted preload of the first bolt is recorded as F', and F' = F × αi is set.

[0025] Furthermore, when the central control processor determines that the angle between the first support member and the structural wall meets the standard, the central control processor controls the distance detector to detect the gap Da between the first support member and the structural wall. The central control processor has a first preset gap size D1 and a second preset gap size D2.

[0026] If Da≤Da1, the central control processor determines that the gap between the first support and the structural wall meets the standard, and performs step s2 to complete the installation of the second support.

[0027] If Da1 < Da ≤ Da2, the central control processor uses α1 to adjust the preload of each of the first bolts set on the first support member;

[0028] If Da > Da2, the central control processor uses α2 to adjust the preload of each of the first bolts set on the first support member;

[0029] When the central control processor uses αi to adjust the preload F of each bolt, i = 1, 2, and for the preload F” of the first bolt after adjustment, F” = F0 × αi, where F0 is the preload of the first bolt when the central control processor determines that the angle between the first support and the structural wall meets the standard.

[0030] Furthermore, when the central control processor determines that the angle between the first support member and the structural wall does not meet the standard,

[0031] If θa≤θa2 and the angle between the first support member and the structural wall is downward, the central control processor determines to adjust the preload of the first bolt located at the bottom of the first support member; if θa≤θa2 and the angle between the first support member and the structural wall is upward, the central control processor determines to adjust the preload of the first bolt at the top.

[0032] If θa > θa2 and the angle between the first support member and the structural wall is downward, the central control processor determines to adjust the preload of the two bolts of the bottommost first bolt. If θa > θa2 and the angle between the first support member and the structural wall is upward, the central control processor determines to adjust the preload of the two bolts of the topmost first bolt.

[0033] Furthermore, in step s2, during the process of tightening the second support member, the central control processor adjusts the preload of the corresponding second bolt on the second support member to the corresponding value according to the angle between the second support member and the structural beam, and adjusts the preload of each second bolt to the corresponding value according to the gap size between the second support member and the structural beam.

[0034] Furthermore, in step s3, when the connecting bolts fix the first support member and the second support member relative to each other, the central control processor controls the angle detector to detect the included angle θb between the first support member and the second support member, and determines whether the preload Fa of the connecting bolts needs to be adjusted based on θb.

[0035] If θb = 90°, the central control processor determines that the angle between the first support and the second support meets the standard, and performs step s4 to complete the installation of the reinforcement component;

[0036] If θb > 90°, the central control processor determines that the angle between the first support and the second support does not meet the standard and adjusts Fa according to the difference between θb and 90°.

[0037] If θb < 90°, the central control processor detects the angle between the first support member and the structural wall to determine the first bolt whose preload needs to be adjusted and the preload of each first bolt whose preload needs to be adjusted after adjustment. It also determines the second bolt whose preload needs to be adjusted and the preload of each second bolt whose preload needs to be adjusted after adjustment based on the angle between the second support member and the structural beam.

[0038] Furthermore, when the angle θb between the first support member and the second support member is greater than 90°, the difference Δθb between θb and 90° is compared with each preset angle difference. Based on the comparison result, the corresponding preset connection preload adjustment coefficient Fa is selected. The central control processor has a first preset angle difference Δθb1, a second preset angle difference Δθb2, a first preset connection preload adjustment coefficient β1, a second preset connection preload adjustment coefficient β2, and a third preset connection preload adjustment coefficient β3, wherein Δθb1 < Δθb2, 1 < β1 < β2 < β3 < 1.5.

[0039] If △θb≤△θb1, the central control processor uses β1 to adjust the connection preload Fa of the connecting bolt;

[0040] If △θb1<△θb≤△θb2, the central control processor uses β2 to adjust the connection preload Fa of the connecting bolt;

[0041] If △θb>△θb2, the central control processor uses β3 to adjust the connection preload Fa of the connecting bolt;

[0042] When the central control processor uses βk to adjust the connection preload Fa of the connecting bolt, k = 1, 2, 3 is set, the adjusted connection preload is recorded as Fa', and Fa' = Fa × βk is set.

[0043] Furthermore, the central control processor is provided with a critical preload Fmax. When the angle θb between the first support member and the second support member is less than 90° and it is determined that the preload of the adjusted first bolt or the second bolt is greater than Fmax, the central control processor adjusts the preload Fb of the connecting bolt according to the difference between the preload of the first bolt or the second bolt and Fmax. The central control processor is provided with a first preset difference ΔF1, a second preset difference ΔF2, a third preset connection preload adjustment coefficient γ3, a fourth preset connection preload adjustment coefficient γ4, and a fifth preset connection preload adjustment coefficient γ5, where ΔF1 < ΔF2, 1 < γ3 < γ4 < γ5 < 1.4.

[0044] For the adjusted preload F' of the first bolt, the difference between F' and Fmax is denoted as ΔF, and ΔF is set to F' - Fmax.

[0045] If △F≤△F1, the central control processor uses γ1 to adjust the connection preload Fb of the connecting bolt;

[0046] If △F1<△F≤△F2, the central control processor uses γ2 to adjust the connection preload Fb of the connecting bolt;

[0047] If △F>△F2, the central control processor uses γ3 to adjust the connection preload Fb of the connecting bolt;

[0048] For the adjusted preload Fc' of the second bolt, the difference between Fc' and Fmax is denoted as ΔFc, and ΔFc = Fc' - Fmax is set.

[0049] If △Fc≤△F1, the central control processor uses γ1 to adjust the connection preload Fb of the connecting bolt;

[0050] If △F1<△Fc≤△F2, the central control processor uses γ2 to adjust the connection preload Fb of the connecting bolt;

[0051] If △Fc>△F2, the central control processor uses γ3 to adjust the connection preload Fb of the connecting bolt;

[0052] When the central control processor uses γj to adjust the preload Fb of the connecting bolt, j = 3, 4, 5 is set, and the tightening preload of the fixed bolt after adjustment is recorded as Fb', and Fb' = Fb × γj is set.

[0053] Furthermore, after the reinforcement structure is installed, its load-bearing capacity P needs to be tested. Based on the test results, the initial preload of each fixing bolt is adjusted. The central control processor is equipped with a preset load-bearing capacity P0.

[0054] When P < P0, the central control processor increases the preload of each of the fixing bolts;

[0055] When P≥P0, the central control processor determines that the installation of the reinforcement structure meets the requirements and does not adjust the preload of each fixing bolt.

[0056] Compared with the prior art, the beneficial effects of the present invention are as follows: During the installation of the various components of the reinforcement structure, the preload of each bolt used to fix the components is adjusted in real time according to the installation status of each component. This effectively ensures the stability of each component's installation, thereby enabling the entire reinforcement structure to effectively support the building structure and further improving the reinforcement efficiency of the present invention. Simultaneously, the present invention verifies the load-bearing capacity of the reinforcement structure upon completion of installation, further ensuring that the preload of each bolt meets the standards. This verification further improves the reinforcement efficiency of the present invention.

[0057] Furthermore, the central control processor is equipped with several preset angles and several preset preload adjustment coefficients. By detecting the angle θa between the first support member and the structural wall, comparing θa with each preset angle, the initial preload F of each first bolt is adjusted, thereby ensuring that the angle between the first support member and the structural wall meets the standard, effectively ensuring that the installation of the first support member meets the standard, and providing a guarantee for the installation of the overall reinforcement structure.

[0058] Furthermore, the central control processor has several preset gap dimensions. By detecting the gap dimension Da between the first support member and the structural wall, comparing Da with each preset gap dimension, and adjusting the initial preload F of each first bolt, the gap dimension between the first support member and the structural wall is ensured to meet the standard. This effectively ensures that the installation of the first support member meets the standard, provides a guarantee for the installation of the overall reinforcement structure, and further improves the reinforcement efficiency of the reinforcement structure of the present invention.

[0059] Furthermore, the central control processor determines the specific location of the bolts whose preload needs to be adjusted by the angle between the first support member and the structural wall and the orientation of the opening, effectively ensuring that the preload of each first bolt meets the standard, thereby enabling the reinforcement structure to be stably fixed in the corresponding position, further improving the reinforcement efficiency of the reinforcement structure of the present invention.

[0060] Furthermore, the central control processor adjusts the preload of each of the second bolts by controlling the angle and gap between the second support member and the structural beam, thereby ensuring that the angle between the second support member and the structural beam meets the standard. This effectively ensures that the installation of the second support member meets the standard and provides a guarantee for the installation of the overall reinforcement structure.

[0061] Furthermore, after the first support member and the second support member are fixed in their respective positions, the connection preload Fa of the connecting bolts and the preload F of each first bolt are adjusted by detecting whether the included angle θb between the first support member and the second support member is a right angle. Through this setting, the first support member and the second support member are effectively connected into a whole, which improves the overall stability of the reinforcement structure and effectively ensures the reinforcement efficiency of the reinforcement structure of the present invention.

[0062] Furthermore, the central control processor is provided with several preset angle differences and several preset connection preload adjustment coefficients. When θb > 90°, the central control processor compares the difference between θb and 90° Δθb with each preset angle difference, and selects the corresponding preset connection preload adjustment coefficient Fa according to the comparison result. This setting effectively ensures that the first support member and the second support member are tightly connected into a whole, thereby increasing the reinforcement force and further improving the reinforcement efficiency of the reinforcement structure of the present invention.

[0063] Furthermore, the central control processor of the present invention is provided with several preset differences, a preset critical preload Fmax, and several connection preload adjustment coefficients. When θb < 90° and it is determined that the adjusted preload is greater than Fmax, the preload of the connecting bolt is adjusted according to the difference ΔF between the first bolt or the second bolt and Fmax. This setting further ensures the relative stability of the first support and the second support, thereby laying the groundwork for subsequent reinforcement.

[0064] Furthermore, after the reinforcement structure is installed, the central control processor will test its load-bearing capacity to ensure that the reinforcement structure can effectively stabilize the building, thereby further ensuring the reinforcement efficiency of the reinforcement structure.

[0072] Please see Figure 1 and Figure 2 The figures shown are the right view and the front view of the prefabricated building reinforcement structure of the present invention, respectively. The prefabricated building reinforcement structure of the present invention includes:

[0073] The first support member 1 has first connecting ears 11 on both sides of the first support member 2, and each connecting ear has a first connecting hole 14; the first support member 1 also has a plurality of vertically arranged first through holes 13; the end of the first support member 1 also has a first fixing hole 12.

[0074] The second support member 2 has second connecting ears 21 on both sides, and each connecting ear has a second connecting hole (not shown in the figure); the second support member 2 also has several horizontally arranged second through holes (not shown in the figure); the end of the second support member 2 also has a second fixing hole 22.

[0075] A number of first bolts (not shown in the figure) are provided, each first bolt being used to fix the first support member 1 to a corresponding position on the structural wall through the corresponding first through hole 13; the number of first bolts is the same as the number of first through holes.

[0076] Several second bolts (not shown in the figure) are used to fix the second support member 2 to a corresponding position on the structural beam through the corresponding second through hole; the number of second bolts is the same as the number of second through holes.

[0077] A plurality of connecting bolts 4, each connecting bolt 4 being used to pass through the corresponding first connecting hole 14 and the second connecting hole and to be engaged with the connecting nut corresponding to the connecting bolt to fix the first support member 1 and the second support member 2 relative to each other;

[0078] The reinforcing member 3 is disposed between the first support member 1 and the second support member 2 to form a triangular structure with the first support member 1 and the second support member 2; both ends of the reinforcing member 3 are provided with through holes (not shown in the figure);

[0079] The first fixing bolt (not shown in the figure) is used to fix one end of the first support member 1 and the reinforcement member 3 in the corresponding position through the corresponding through hole;

[0080] The second fixing bolt (not shown in the figure) is used to fix the other end of the second support member 2 and the reinforcement member 3 in the corresponding position through the corresponding through hole;

[0081] The central control processor (not shown in the figure) is located outside the reinforcement and is externally connected to an angle detector (not shown in the figure) and a distance detector (not shown in the figure). The angle detector is used to detect whether the included angle θa between the first support member 1 and the structural wall meets the standard during the tightening of the first support member 1 and to determine whether to adjust the preload F of the corresponding first bolt to the corresponding value based on the detection result. The distance detector is used to detect the gap between the first support member 1 and the structural wall to determine whether to adjust the initial preload of each first bolt to the corresponding value.

[0082] Please see Figure 3 As shown, it is an assembly method for the prefabricated building reinforcement structure of the present invention, comprising:

[0083] Step s1: Pre-drill holes in the structural wall and fix the first support 1 with several first bolts. During the process of tightening the first support 1, the central control processor adjusts the pre-tightening force of the corresponding first bolt on the first support 1 to the corresponding value according to the angle between the first support and the structural wall, and adjusts the pre-tightening force of each first bolt to the corresponding value according to the gap size between the first support 1 and the structural wall.

[0084] Step s2: Pre-drill holes in the structural beam and fix the second support member 2 with several second bolts. During the process of tightening the second support member 2, the central control processor adjusts the preload of the corresponding second bolt on the second support member 2 to the corresponding value according to the angle between the second support member 2 and the structural beam, and adjusts the preload of each second bolt to the corresponding value according to the gap size between the second support member 2 and the structural beam wall.

[0085] Step s3: Pass the connecting bolt 4 sequentially through the first connecting lug 11 provided on the first support member 1 and the second connecting lug 21 provided on the second support member 2, and use the connecting nut to clamp the first connecting lug 11 and the second connecting lug 21 to fix the first support member 1 and the second support member 2 relative to each other; The central control processor determines whether to adjust the preload of the connecting bolt 4 to the corresponding value according to the included angle between the first support member 1 and the second support member 2;

[0086] Step s4: Place the reinforcement component at the corresponding position between the first support member 1 and the second support member 2. Pass the first fixing bolt through the first fixing hole in the first support member and one end of the reinforcement component 3 in sequence, and pass the second fixing bolt through the second fixing hole in the second support member 2 and the other end of the reinforcement component 3 in sequence. Use the first fixing nut to cooperate with the first fixing bolt and the second fixing nut to cooperate with the second fixing bolt to fix the reinforcement component 3 at the corresponding position between the first support member 1 and the second support member 2 to complete the installation of the reinforcement component 3.

[0087] Specifically, during the process of tightening the first support member 1, the central control processor controls the angle detector to detect the included angle θa between the first support member 1 and the structural wall, and determines whether to adjust the preload F of the corresponding first bolt based on θa. The first support member 1 is fixed to the corresponding position on the structural wall by four vertically arranged first bolts. The central control processor has a first preset angle θa1, a second preset angle θa2, a first preset preload adjustment coefficient α1, and a second preset preload adjustment coefficient α2, wherein θa1 < θa2, 1 < α1 < α2 < 1.3.

[0088] If θa≤θa1, the central control processor determines that the angle between the first support member 1 and the structural wall meets the standard, and the central control processor controls the distance detector to detect the gap between the first support member 1 and the structural wall to determine whether to adjust the initial preload of each of the first bolts.

[0089] If θa1<θa≤θa2, the central control processor uses α1 to adjust the preload of the corresponding first bolt set on the first support member 1;

[0090] If θa > θa2, the central control processor uses α2 to adjust the preload of the corresponding first bolt set on the first support member 1;

[0091] When the central control processor uses αi to adjust the preload F of each of the first bolts, i = 1, 2, the adjusted preload of the first bolt is recorded as F', and F' = F × αi is set.

[0092] The central control processor of this invention has several preset angles and several preset preload adjustment coefficients. By detecting the angle θa between the first support member 1 and the structural wall, comparing θa with each preset angle, and adjusting the initial preload F of each first bolt, it ensures that the angle between the first support member 1 and the structural wall meets the standard, effectively ensuring that the installation of the first support member 1 meets the standard, and providing a guarantee for the installation of the overall reinforcement structure.

[0093] Specifically, when the central control processor determines that the angle between the first support member 1 and the structural wall meets the standard, the central control processor controls the distance detector to detect the gap Da between the first support member 1 and the structural wall. The central control processor has a first preset gap size D1 and a second preset gap size D2.

[0094] If Da≤Da1, the central control processor determines that the gap between the first support member 1 and the structural wall meets the standard, and performs step s2 to complete the installation of the second support member 2;

[0095] If Da1 < Da ≤ Da2, the central control processor uses α1 to adjust the preload of each of the first bolts set on the first support member 1;

[0096] If Da > Da2, the central control processor uses α2 to adjust the preload of each of the first bolts set on the first support member 1;

[0097] When the central control processor uses αi to adjust the preload F of each bolt, i = 1, 2, and for the preload F” of the first bolt after adjustment, F” = F0 × αi, where F0 is the preload of the first bolt when the central control processor determines that the angle between the first support 1 and the structural wall meets the standard.

[0098] The central control processor of this invention has several preset gap sizes. By detecting the gap size Da between the first support member 1 and the structural wall, and comparing Da with each preset gap size, the initial preload F of each first bolt is adjusted, thereby ensuring that the gap size between the first support member 1 and the structural wall meets the standard. This effectively ensures that the installation of the first support member 1 meets the standard, provides a guarantee for the installation of the overall reinforcement structure, and further improves the reinforcement efficiency of the reinforcement structure of this invention.

[0099] Specifically, when the central control processor determines that the angle between the first support member 1 and the structural wall does not meet the standard,

[0100] If θa≤θa2 and the angle between the first support member 1 and the structural wall is downward, the central control processor determines to adjust the preload of the first bolt located at the bottom of the first support member 1; if θa≤θa2 and the angle between the first support member 1 and the structural wall is upward, the central control processor determines to adjust the preload of the first bolt at the top.

[0101] If θa > θa2 and the angle between the first support member 1 and the structural wall is downward, the central control processor determines to adjust the preload of the two bolts of the bottom first bolt. If θa > θa2 and the angle between the first support member 1 and the structural wall is upward, the central control processor determines to adjust the preload of the two bolts of the top first bolt.

[0102] The central control processor of the present invention determines the specific position of the bolt whose preload needs to be adjusted by the angle between the first support member 1 and the structural wall and the orientation of the opening, which effectively ensures that the preload of each first bolt meets the standard, thereby enabling the reinforcement structure to be stably fixed in the corresponding position, and further improving the reinforcement efficiency of the reinforcement structure of the present invention.

[0103] Specifically, in step s2, during the process of tightening the second support member 2, the central control processor adjusts the preload of the corresponding second bolt on the second support member 2 to the corresponding value according to the angle between the second support member 2 and the structural beam, and adjusts the preload of each second bolt to the corresponding value according to the gap size between the second support member and the structural beam.

[0104] The central control processor of the present invention adjusts the preload of each of the second bolts by adjusting the angle and gap between the second support member 2 and the structural beam, thereby ensuring that the angle between the second support member 2 and the structural beam meets the standard, effectively ensuring that the installation of the second support member 2 meets the standard, and providing a guarantee for the installation of the overall reinforcement structure.

[0105] Specifically, in step s3, when the connecting bolt 4 fixes the first support 1 and the second support 2 relative to each other, the central control processor controls the angle detector to detect the included angle θb of the first support 1 and the second support 2, and determines whether the preload Fa of the connecting bolt 4 needs to be adjusted based on θb.

[0106] If θb = 90°, the central control processor determines that the angle between the first support member 1 and the second support member 2 meets the standard, and performs step s4 to complete the installation of the reinforcement component;

[0107] If θb > 90°, the central control processor determines that the angle between the first support member 1 and the second support member 2 does not meet the standard and adjusts Fa according to the difference between θb and 90°.

[0108] If θb < 90°, the central control processor detects the angle between the first support member 1 and the structural wall to determine the first bolt whose preload needs to be adjusted and the preload of each first bolt whose preload needs to be adjusted after adjustment. It also determines the second bolt whose preload needs to be adjusted and the preload of each second bolt whose preload needs to be adjusted after adjustment based on the angle between the second support member 2 and the structural beam.

[0109] After the first support member 1 and the second support member 2 are fixed in their respective positions, the present invention determines whether it is necessary to adjust the preload Fa of the connecting bolt 4 and the preload F of each of the first bolts by detecting whether the included angle θb between the first support member 1 and the second support member 2 is a right angle. Through this setting, the first support member 1 and the second support member 2 are effectively connected into a whole, which improves the overall stability of the reinforcement structure and effectively ensures the reinforcement efficiency of the reinforcement structure of the present invention.

[0110] Specifically, when the angle θb between the first support member 1 and the second support member 2 is greater than 90°, the difference Δθb between θb and 90° is compared with each preset angle difference. Based on the comparison result, the corresponding preset connection preload adjustment coefficient Fa is selected. The central control processor has a first preset angle difference Δθb1, a second preset angle difference Δθb2, a first preset connection preload adjustment coefficient β1, a second preset connection preload adjustment coefficient β2, and a third preset connection preload adjustment coefficient β3, wherein Δθb1 < Δθb2, 1 < β1 < β2 < β3 < 1.5.

[0111] If △θb≤△θb1, the central control processor uses β1 to adjust the connection preload Fa of the connecting bolt 4;

[0112] If △θb1<△θb≤△θb2, the central control processor uses β2 to adjust the connection preload Fa of the connecting bolt 4;

[0113] If △θb>△θb2, the central control processor uses β3 to adjust the connection preload Fa of the connecting bolt 4;

[0114] When the central control processor uses βk to adjust the connection preload Fa of the connecting bolt 4, k is set to 1, 2, 3, and the adjusted connection preload is recorded as Fa', and Fa' is set to Fa×βk.

[0115] The central control processor of the present invention is provided with several preset angle differences and several preset connection preload adjustment coefficients. When θb > 90°, the central control processor compares the difference between θb and 90° Δθb with each preset angle difference, and selects the corresponding preset connection preload adjustment coefficient Fa according to the comparison result. This setting effectively ensures that the first support member 1 and the second support member 2 are tightly connected into a whole, thereby increasing the reinforcement force and further improving the reinforcement efficiency of the reinforcement structure of the present invention.

[0116] Specifically, the central control processor has a critical preload Fmax. When the angle θb between the first support member 1 and the second support member 2 is less than 90° and it is determined that the preload of the adjusted first bolt or the second bolt is greater than Fmax, the central control processor adjusts the preload Fb of the connecting bolt 4 according to the difference between the preload of the first bolt or the second bolt and Fmax. The central control processor has a first preset difference ΔF1, a second preset difference ΔF2, a third preset connection preload adjustment coefficient γ3, a fourth preset connection preload adjustment coefficient γ4, and a fifth preset connection preload adjustment coefficient γ5, where ΔF1 < ΔF2, 1 < γ3 < γ4 < γ5 < 1.4.

[0117] For the adjusted preload F' of the first bolt, the difference between F' and Fmax is denoted as ΔF, and ΔF is set to F' - Fmax.

[0118] If △F≤△F1, the central control processor uses γ1 to adjust the connection preload Fb of the connecting bolt 4;

[0119] If △F1<△F≤△F2, the central control processor uses γ2 to adjust the connection preload Fb of the connecting bolt 4;

[0120] If △F>△F2, the central control processor uses γ3 to adjust the connection preload Fb of the connecting bolt 4;

[0121] For the adjusted preload Fc' of the second bolt, the difference between Fc' and Fmax is denoted as ΔFc, and ΔFc = Fc' - Fmax is set.

[0122] If △Fc≤△F1, the central control processor uses γ1 to adjust the connection preload Fb of the connecting bolt 4;

[0123] If △F1<△Fc≤△F2, the central control processor uses γ2 to adjust the connection preload Fb of the connecting bolt 4;

[0124] If △Fc>△F2, the central control processor uses γ3 to adjust the connection preload Fb of the connecting bolt 4;

[0125] When the central control processor uses γj to adjust the preload Fb of the connecting bolt 4, j = 3, 4, 5 is set, and the tightening preload of the fixed bolt after adjustment is recorded as Fb', and Fb' = Fb × γj is set.

[0126] The central control processor of the present invention is provided with several preset differences, a preset critical preload Fmax, and several connection preload adjustment coefficients. When θb < 90° and it is determined that the adjusted preload is greater than Fmax, the preload of the connecting bolt is adjusted according to the difference ΔF between the first bolt or the second bolt and Fmax. This setting further ensures the relative stability of the first support member 1 and the second support member 2, thereby laying the groundwork for subsequent reinforcement.

[0127] Specifically, after the reinforcement structure is installed, its load-bearing capacity P needs to be tested. Based on the test results, the initial preload of each fixing bolt is adjusted. The central control processor has a preset load-bearing capacity P0.

[0128] When P < P0, the central control processor increases the preload of each of the fixing bolts;

[0129] When P≥P0, the central control processor determines that the installation of the reinforcement structure meets the requirements and does not adjust the preload of each fixing bolt.

[0130] Once the reinforcement structure is installed, the central control processor of this invention will test its load-bearing capacity to ensure that the reinforcement structure can effectively stabilize the building, thereby further ensuring the reinforcement efficiency of the reinforcement structure.
