Abstract
Description
Technical Field
[0001] The present application relates to the technical field of building reinforcement, and in particular to a reinforcement fastening assembly, a building reinforcement device and a building reinforcement method. Background Art
[0002] At present, the secondary structure of construction projects and the structural reinforcement of old buildings usually require drilling holes for embedding steel bars on the reinforced concrete components of the original building, and then planting steel bars by filling the embedding holes with structural glue and anchoring them. For the vertical upward reinforcement planting method, if there is no structural support before the structural glue is cured, the implanted steel bars will fall due to their own weight, resulting in a decrease in the implantation depth of the steel bars or the problem of steel bars falling off, causing safety hazards. In the related technology, multiple wooden wedges are often arranged in the circumferential direction of the steel bars and inserted into the embedding holes. The steel bars are fixed in the embedding holes where the structural glue has not been cured by the wooden wedges, and the structural glue is ensured to surround the outer circumference of the steel bars to improve the connection strength between the steel bars and the original building. However, a single steel bar under this fixing method needs to be fixed by multiple wooden wedges inserted into the embedding holes in turn. Not only are the operating steps complicated, but the embedding efficiency is also low. Moreover, when the number of implanted steel bars is required to be large, it is also easy to cause the operation to be affected by the insufficient number of wooden wedges, resulting in a decrease in work efficiency. Summary of the invention

[0041] The embodiments of the present application disclose a rebar fastening assembly, a building reinforcement device and a building reinforcement method. The rebar fastening assembly can be applied to the building reinforcement device to fix the steel bars implanted in the rebar holes.
[0042] In order to facilitate understanding of the structure of the anchor bolt fastening assembly and the building reinforcement device, further description will be given below in conjunction with embodiments and drawings.
[0043] See also Figure 1 The embodiment of the present application provides a building reinforcement device 200 for reinforcing a building component 300. The building component 300 is provided with a rebar hole 301, which is used to fill the structural adhesive and plant the rebar 201. The building reinforcement device 200 includes a rebar 201 and a rebar fastening assembly 100. The rebar fastening assembly 100 is used to fix the rebar 201 while the rebar 201 is implanted into the rebar hole 301 of the building component 300 and waiting for the structural adhesive to cure. Figure 2 and Figure 3Specifically, the anchor bolt fastening assembly 100 includes a support plate 10, a fastener 20 and a fixing portion 30. The support plate 10 is provided with a first mounting hole 11 and a second mounting hole 12 at intervals and through-through. The first mounting hole 11 is used to be sleeved on the outer periphery of the steel bar 201. The fastener 20 can be movably inserted into the second mounting hole 12. The fixing portion 30 is provided on one side of the support plate 10, and the fixing portion 30 has a compressible deformation amount. The fixing portion 30 is used to be compressed and deformed when the fastener 20 extends into the anchor bolt hole 301.
[0044] By arranging a fixing portion 30 on one side of the support plate 10, and making the first mounting hole 11 and the second mounting hole 12 spaced and penetrated on the support plate 10, the support plate 10 can be sleeved on the outer periphery of the steel bar 201 through the first mounting hole 11, so as to facilitate the fixing portion 30 to enter the anchor hole 301, and at the same time, the fastener 20 can be movably inserted into the second mounting hole 12, so that the fastener 20 can move in a direction close to or away from the anchor hole 301. When the fastener 20 extends into the anchor hole 301 through the second mounting hole 12, the fixing portion 30 is squeezed and compressed to deform, so that the fixing portion 30 generates a lateral squeezing force on the steel bar 201. At this time, the fastener 20 and the fixing portion 30 are jointly supported between the steel bar 201 and the hole wall of the anchor hole 301, and an extrusion friction force is formed between the steel bar 201 and the fastener 20 and the fixing portion 30, so that the steel bar 201 is fixed relative to the anchor hole 301, and the steel bar 201 is effectively prevented from falling due to its own weight. It can be seen that the use of the rebar fastening assembly 100 provided in the embodiment of the present application can reduce the number of parts required to fix the rebar 201, thereby simplifying the operating steps of rebar fixing and improving rebar planting efficiency, while also being conducive to meeting the needs of planting multiple rebars 201 and ensuring the operational stability of the structural parts during the rebar planting process.
[0045] In some embodiments, the diameter of the anchor hole 301 is 4mm-10mm larger than the diameter of the steel bar 201. For example, the diameter of the anchor hole 301 can be 5mm, 6mm, 7mm, 8mm or 9mm larger than the diameter of the steel bar 201. This ensures that there is a sufficient distance between the steel bar 201 and the hole wall of the anchor hole 301, so that the outer periphery of the steel bar 201 is covered with enough structural adhesive to ensure the connection reliability between the steel bar 201 and the building component 300 and improve the bonding strength between the steel bar 201 and the building component 300. When the diameter of the anchor hole 301 is too large, it is easy to cause deviation or deflection of the anchor, affecting the construction accuracy and reducing the safety performance of the node. When the diameter of the anchor hole 301 is too small, the thickness of the adhesive layer on the outer periphery of the steel bar 201 is too small, and the quality of the anchor is reduced.
[0046] Optionally, the diameter of the first mounting hole 11 is the same as or approximately the same as the diameter of the steel bar 201 .
[0047] In this way, on the one hand, the relative position of the support plate 10 and the steel bar 201 can be kept fixed, and the situation where the anchor fastener 20 falls off from the steel bar 201 can be avoided, so as to facilitate the assembly of the support plate 10 and the steel bar 201 in advance, reduce the number of scattered parts in the process of planting the steel bar 201, and facilitate the planting and fastening of the steel bar 201, so that the support plate 10 can move toward the direction close to the anchor hole 301 by overcoming the friction force after the steel bar 201 is inserted into the anchor hole 301, so that the fixing part 30 is pressed into the anchor hole 301. On the other hand, by sleeve-arranging the support plate 10 on the outer periphery of the steel bar 201, the fixing part 30 on the support plate 10 can also be inserted into the anchor hole 301 together with the steel bar 201 during the process of the steel bar 201 being implanted into the anchor hole 301, so as to save the steps and time of inserting wooden wedges one by one in the related technology, simplify the operation steps of anchoring, and further improve the efficiency of anchoring.
[0048] It can be understood that in other embodiments, the diameter of the first mounting hole 11 may also be slightly larger than the diameter of the steel bar 201 .
[0049] In some embodiments, the support plate 10 is provided with a first opening 13, and the first opening 13 extends from the edge of the support plate 10 to the center of the support plate 10 to connect to the first mounting hole 11. This is beneficial to the installation and removal of the support plate 10 and the steel bar 201, so that the support plate 10 can meet the assembly mode of being installed on the periphery of the steel bar 201 before or after the steel bar 201 is implanted into the steel bar embedding hole 301, so as to improve the flexibility and convenience of the use of the steel bar embedding fastening assembly 100, so that the steel bar embedding fastening assembly 100 can be applied to more application scenarios, and on the other hand, it can also help to adapt the support plate 10 to steel bars 201 of different sizes, avoiding assembly abnormalities due to dimensional tolerances.
[0050] Optionally, the size of the first opening 13 gradually decreases from the edge of the support plate 10 to the center of the support plate 10. This can facilitate the support plate 10 to be sleeved on the outer periphery of the steel bar 201 through the first opening 13, so as to facilitate the assembly of the support plate 10 and the steel bar 201, and can also increase the locking strength of the support plate 10 to the steel bar 201, so as to increase the opening resistance of the inner ring of the support plate 10, and avoid the first opening 13 from being easily opened under the squeezing action of the steel bar 201 or the fixing part 30.
[0051] In some embodiments, the number of the fixing portions 30 is at least two, the at least two fixing portions 30 and the second mounting hole 12 are evenly distributed along the circumferential direction of the first mounting hole 11 , and the at least two fixing portions 30 are symmetrically arranged with the second mounting hole 12 as the center.
[0052] In this way, the fixing parts 30 and the fasteners 20 are evenly distributed on the periphery of the steel bar 201, which can help improve the uniformity of the extrusion friction force on the steel bar 201, so as to improve the stability of the steel bar 201 in the rebar hole 301, so that the steel bar 201 implanted in the rebar hole 301 can also remain stable and reliable before the structural adhesive is cured. At the same time, at least two fixing parts 30 are symmetrically arranged with the second mounting hole 12 as the center, which can also help to transmit the extrusion force when the fastener 20 enters the rebar hole 301, improve the force transmission effect, and make the deformation of each fixing part 30 more uniform, so as to help the steel bar 201 be located in the center of the rebar hole 301, improve the distribution uniformity of the structural adhesive on the periphery of the steel bar 201, and thus improve the connection reliability between the steel bar 201 and the building component 300.
[0053] In addition, by limiting the number of fixing parts 30 to at least two, the anchor bolt fastening assembly 100 has at least three extrusion support points, so as to improve the fixing effect of the anchor bolt fastening assembly 100 on the steel bar 201, which is more reliable than the fixing method with two extrusion support points. Moreover, the support plate 10 is provided with at least two fixing parts 30, which can save operation steps compared with the fixing method of inserting multiple wooden wedges in sequence in the related art. It is only necessary to push the support plate 10 toward the anchor bolt hole 301 to simultaneously insert multiple fixing parts 30 into the anchor bolt hole 301, so as to improve the anchor bolt efficiency.
[0054] It is understandable that in some other embodiments, the number of the fixing portion 30 and the second mounting hole 12 may also be one, and the first opening 13 is located between the fixing plate and the second mounting hole 12 .
[0055] This embodiment is described by taking an example in which the number of the fixing portions 30 is two and the number of the second mounting hole 12 and the fastener 20 is one.
[0056] Optionally, the first opening 13 is located between two adjacent fixing portions 30. Thus, the first opening 13 is away from the fastener 20, and when the fastener 20 is inserted into the anchor hole 301, the fastener 20 pushes the steel bar 201 to squeeze the fixing portion 30, and the fixing portion 30 is compressed and deformed and generates a lateral extrusion force on the building component 300 and the steel bar 201 to share the force on the first opening 13, reduce the opening deformation of the first opening 13 when the fastener 20 is inserted into the anchor hole 301, and keep the support plate 10 and the steel bar 201 relatively fixed.
[0057] It can be understood that in other embodiments, the first opening 13 may also be located between the fixing portion 30 and the second mounting hole 12 .
[0058] Optionally, the first opening 13 is disposed on a side of the support plate 10 away from the second mounting hole 12. Thus, the first opening 13 is away from the fastener 20, which is beneficial to reduce the force transmitted from the fastener 20 to the first opening 13, and reduce the opening deformation of the first opening 13 during the process of inserting the fastener 20 into the anchor hole 301, so that the support plate 10 and the steel bar 201 remain relatively fixed.
[0059] Optionally, the first opening 13 is located between two adjacent fixing portions 30 , and the first opening 13 and the second mounting hole 12 are symmetrically arranged with the center line of the first mounting hole 11 as the center, thereby facilitating improving the stability of the first opening 13 .
[0060] In some embodiments, considering that the structural adhesive is not solidified when the steel bar 201 is implanted in the anchor hole 301, the structural adhesive may drip downward due to its own gravity, resulting in a reduction in the structural adhesive in the anchor hole 301, affecting the connection reliability between the steel bar 201 and the building component 300. Based on this, the area of the support plate 10 is larger than the diameter of the anchor hole 301 to block the anchor hole 301. This can avoid the dripping or overflow of the structural adhesive in the anchor hole 301, improve the anchor effect, and ensure the connection reliability between the steel bar 201 and the building component 300.
[0061] Optionally, the outer diameter of the support plate 10 may be twice the diameter of the anchor hole 301 , thereby reserving sufficient size for the fixing portion 30 and the fastener 20 and ensuring the sealing effect on the anchor hole 301 .
[0062] Optionally, considering that the shape of the rebar holes 301 is mostly circular holes, based on this, the shape of the support plate 10 can be a circular ring, that is, the edge shape of the support plate 10 is circular, so as to adapt to the shapes of the steel bar 201 and the rebar hole 301. This is beneficial for reducing the area of the support plate 10 while ensuring that the rebar hole 301 is blocked, so as to reduce the weight of the support plate 10 and facilitate the installation and transportation of the rebar fastening assembly 100. At the same time, it is also beneficial to open the first opening 13 so that the support plate 10 can be sleeved on the outer periphery of the steel bar 201.
[0063] It can be understood that in other embodiments, the edge shape of the support plate 10 can also be a rectangle, a triangle, a polygon or an irregular shape.
[0064] In some embodiments, a guide boss 40 extending along the center line direction of the second mounting hole 12 is provided on one side of the support plate 10 , and the second mounting hole 12 is provided through the guide boss 40 .
[0065] In this way, the guide boss 40 can guide the movement direction of the fastener 20 in the second mounting hole 12, so that the fastener 20 can be inserted into the anchor hole 301 in a direction parallel to the steel bar 201, which is beneficial to increase the contact area between the fastener 20 and the steel bar 201, thereby facilitating increasing the force transmission efficiency between the fastener 20 and the steel bar 201, so that the force of the fastener 20 inserted into the anchor hole 301 can be transmitted to the fixing part 30 through the steel bar 201, and then the lateral extrusion force formed by the fixing part 30 is transmitted to the steel bar 201, so as to improve the stability of the steel bar 201 in the anchor hole 301, and effectively avoid the situation where the fastener 20 and the steel bar 201 or the hole wall of the anchor hole 301 interfere with each other due to the deviation of the movement direction of the fastener 20, thereby affecting the stability of the steel bar 201 in the anchor hole 301. In addition, by setting and controlling the size of the second mounting hole 12, the relative position of the fastener 20 and the guide boss 40 can be kept fixed, which is beneficial for fixing the fastener 20, so that the fastener 20 can be assembled on the guide boss 40 for use before the steel bar 201 is implanted into the rebar hole 301, which is beneficial for rebar fixation, improves rebar embedding efficiency, and avoids the inconvenience of operation caused by scattered components.
[0066] Optionally, the guide boss 40 is located on the outer periphery of the first mounting hole 11, and the size of the guide boss 40 gradually decreases from the end where the guide boss 40 is connected to the support plate 10 toward the direction away from the support plate 10, and the side of the guide boss 40 close to the first mounting hole 11 is provided with an arc surface so that the guide boss 40 is installed in a fit with the steel bar 201.
[0067] In this way, by setting the arc surface, it is helpful to reduce the distance between the fastener 20 and the steel bar 201, so that the fastener 20 is closer to the steel bar 201, so as to facilitate the steel bar 201 to squeeze the fixing part 30 to make it compress and deform, thereby ensuring the extrusion friction of the steel bar 201 and improving the stability of the steel bar 201 in the anchor hole 301. At the same time, by setting the size of the guide boss 40 to gradually decrease in the direction away from the support plate 10, the structural reliability of the guide boss 40 can also be improved to ensure the guiding effect of the guide boss 40 on the fastener 20.
[0068] Optionally, the guide boss 40 and the fixing portion 30 are arranged on the same side of the support plate 10. This can not only help guide the movement direction of the fastener 20, but also squeeze the steel bar 201 through the guide boss 40 to increase the squeezing friction force on the steel bar 201 and ensure the structural stability of the steel bar 201 in the anchor hole 301. In addition, the size of the guide boss 40 gradually decreases from the support plate 10 to the anchor hole 301, and a slope can be formed on the outer periphery of the guide boss 40 to guide it into the anchor hole 301, so as to facilitate pressing the fixing portion 30 and the guide boss 40 into the anchor hole 301.
[0069] In some embodiments, the fixing portion 30 is cylindrical in shape, which is beneficial to increase the contact area between the fixing portion 30 and the steel bar 201 and improve the force transmission efficiency, so as to improve the structural stability of the steel bar 201 in the anchor hole 301.
[0070] It can be understood that in other embodiments, the shape of the fixing portion 30 may also be a prism or a sphere.
[0071] Optionally, an anti-skid layer is provided on the periphery of the fixing portion 30 , so as to increase the friction between the fixing portion 30 and the steel bar 201 , so as to improve the stability of the steel bar 201 in the anchor hole 301 .
[0072] Optionally, the anti-slip layer may be a wavy structure with ups and downs, or a coating material with a large friction coefficient, or a regular or irregular structure of protrusions and depressions.
[0073] Optionally, see Figure 1 , the diameter of the fixing part 30 is d1 (i.e. the maximum dimension of the fixing part 30 in the radial direction is d1), the radius difference between the anchor hole 301 and the steel bar 201 is t, d1 / t=1.10-1.50, for example, d1 / t can be 1.15, 1.20, 1.30, 1.35, 1.40 or 1.45, etc., so as to reserve sufficient compression deformation for the fixing part 30 and ensure that the fixing part 30 and the fastener 20 can fasten the steel bar 201 in the anchor hole 301.
[0074] Optionally, the material of the fixing part 30 is any one of polyethylene, rubber or polypropylene, so that the fixing part 30 has compressible properties. The material of the fixing part 30 can be set according to actual needs and is not limited here.
[0075] Optionally, the material of the support plate 10 and the fixing part 30 is the same or similar, that is, the material of the support plate 10 can also be any one of polyethylene, rubber or polypropylene, which is beneficial to improve the connection reliability between the support plate 10 and the fixing part 30, and is beneficial to the support plate 10 and the fixing part 30 being manufactured in an integral molding manner to improve molding efficiency and quality.
[0076] In some embodiments, please refer to Figure 1 The diameter of the fastener 20 is d2, d2 / t=1.00-1.10, for example, d2 / t can be 1.00, 1.05, 1.08 or 1.10, etc. This ensures that the fastener 20 can squeeze the steel bar 201 and the fixing part 30 when inserted into the steel bar planting hole 301, so that the fixing part 30 forms a lateral squeezing force on the steel bar 201.
[0077] Optionally, the diameter of the second mounting hole 12 is the same or substantially the same as the diameter of the fastener 20. This can help keep the relative position of the fastener 20 fixed after being inserted into the second mounting hole 12, so as to facilitate the fixing of the fastener 20, so that the fastener 20 can be assembled on the guide boss 40 for standby use before the steel bar 201 is implanted into the anchor hole 301, so as to facilitate the anchor fixation, improve the anchor efficiency, and avoid the inconvenience of operation caused by scattered parts. When the fastener 20 needs to be inserted into the anchor hole 301, the fastener 20 can be squeezed or knocked by external force, so that the fastener 20 moves relative to the second mounting hole 12 until it is pushed into the anchor hole 301, so as to achieve the purpose of compressing the fixing part 30.
[0078] Optionally, the material of the fastener 20 can be any one of steel, iron, carbon fiber or cement, and the hardness of the fastener 20 is greater than the hardness of the fixing portion 30. Exemplarily, the fastener 20 is a steel nail, and the head of the steel nail is provided with a flat hammering end, and the side of the hammering end close to the first mounting hole 11 is a flat surface or a curved surface, so that the steel nail is closer to the outer periphery of the steel bar.
[0079] This ensures the reliability of the fastener 20 , meets the operational requirements of the fastener 20 being squeezed or knocked into the anchor hole 301 , and ensures that the fixing portion 30 can generate compression deformation when the fastener 20 is inserted into the anchor hole 301 .

[0083] S11 , drilling holes in the building component 300 to obtain anchor holes 301 , and filling the anchor holes 301 with structural adhesive.
[0084] Optionally, before drilling the anchor hole 301 in the building component 300, the surface of the building component 300 should be roughened and cleaned, and the drilling position and hole diameter of the anchor hole 301 should be marked on the surface of the building component 300. Before filling the structural adhesive, the anchor hole 301 should also be cleaned by brushing or other methods to ensure that there is no dust in the hole.
[0085] Optionally, structural glue is filled into the rebar hole 301 using an electric glue gun to fill the bottom of the rebar hole 301 with structural glue, and the amount of glue injected is 2 / 3 of the depth of the rebar hole 301, thereby reserving space for the steel bar 201 and the rebar fastening assembly 100 and reducing overflow glue waste.
[0086] S12, sleeve the support plate 10 onto the outer periphery of the steel bar 201.
[0087] This can help reduce the number of scattered parts after the steel bars 201 are planted, thereby simplifying the steel bar planting steps and improving the steel bar planting efficiency.
[0088] Optionally, the support plate 10 and the steel bar 201 may be assembled by inserting the steel bar 201 into the first mounting hole 11 , or the support plate 10 may be fixed to the outer periphery of the steel bar 201 through the first opening 13 .
[0089] S13, inserting the steel bar 201 into the steel bar embedding hole 301 of the building component 300.
[0090] Optionally, a one-way rotation method is adopted when inserting the steel bar 201, so as to increase the bonding area between the steel bar 201 and the structural adhesive, avoid the generation of bubbles, and reduce the amount of adhesive overflow.
[0091] It can be understood that in other embodiments, the above-mentioned steps S12 and S13 can also be performed by first executing step S13 and then executing step S12, that is, first inserting the steel bar 201 into the anchor hole 301 and then putting the support plate 10 on the outer periphery of the steel bar 201, so as to improve the flexibility of assembling the support plate 10 and the steel bar 201.
[0092] S2, pushing the support plate 10 to move toward the direction close to the anchor hole 301 until the fixing portion 30 is inserted into the anchor hole 301.
[0093] S3, inserting the fastener 20 into the anchor hole 301 through the second mounting hole 12.
[0094] By inserting the fixing portion 30 first and then inserting the fastener 20 , the compressible deformation performance of the fixing portion 30 can be utilized to form a lateral squeezing force on the steel bar 201 , thereby improving the stability of the steel bar 201 in the anchor hole 301 .
[0095] Optionally, the fixing part 30 can be inserted into the anchor hole 301 by manual pressing, and the fastener 20 can be inserted into the anchor hole 301 by hammering, so that the fastener 20, the fixing part 30, and the steel bar 201 can form an extrusion friction force in the anchor hole 301 to prevent the steel bar 201 from falling due to its own weight.
[0096] Optionally, the fastener 20 can be installed in the second installation hole 12 before the above step S13, so as to reduce the number of scattered parts after the steel bar 201 is planted, simplify the steel bar planting steps, and improve the steel bar planting efficiency.
[0097] In some embodiments, the building reinforcement method further comprises step S4:
[0098] S4. Wait for the structural adhesive to solidify according to the ambient temperature, and keep the steel bar 201 fixed during this process.
[0099] This can help improve the connection reliability between the steel bar 201 and the building component 300, thereby improving the quality of building reinforcement.
[0100] It can be understood that, since the building reinforcement method uses the building reinforcement device 200 described in the above embodiment to reinforce the building component 300, the building reinforcement method has the beneficial effects of the building reinforcement device 200 described in the above embodiment, which will not be repeated here.
