Description

Technical Field

[0001] The invention relates to the technical field of civil engineering, and in particular to a recycled geopolymer concrete beam-column node structure with a self-repairing function. Background Art

[0002] Concrete is one of the most commonly used materials in the construction industry, with advantages such as high strength and good durability. However, concrete will also suffer various damages during use, such as cracks and spalling, which will affect its mechanical properties and overall performance. With the widespread application of concrete and steel, concrete beam-column node structures have gradually become an important part of building structures. In long-term research and practice, people have gradually realized the importance of node structures and began to conduct in-depth research and improvements on them.

[0003] In the existing beam-column node structure, the crossbeam and the column are often connected together by a docking installation method. This method can stably install and fix the beam and the column, and has a good earthquake resistance effect. During the installation process, the crossbeam needs to be docked and installed with the column by a hoisting method, and the crossbeam is inserted into the corresponding installation groove on the beam and the column. Due to the lack of auxiliary positioning of the crossbeam and the column, the position and angle need to be adjusted multiple times during docking to accurately achieve the connection between the two, which makes it difficult to quickly and accurately assemble the beam and the column.

[0004] In summary, how to solve the problem that the existing beam-column node structure lacks auxiliary positioning of the beams and columns, resulting in the difficulty of rapid and accurate assembly of the beams and columns has become a difficult problem that needs to be solved in the current field. Therefore, it is necessary to propose a recycled geopolymer concrete beam-column node structure with self-repairing function that can assist in the positioning of the beams and columns. Summary of the invention

[0005] To solve the above problems, the present invention provides a recycled geopolymer concrete beam-column node structure with self-repairing function, which can effectively assist the positioning of beams and columns through the design of positioning auxiliary components, so that the beams and columns can be quickly docked and assembled.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a recycled geopolymer concrete beam-column node structure with self-repairing function, including columns and beams, the columns are fixedly connected with a plurality of grooves, and both ends of the beams are fixedly connected with joints; the grooves are provided with docking components for beam-column docking, fixing components for fixing the positions of beams and columns, and positioning auxiliary components for assisting beam-column docking.

[0007] The positioning auxiliary components include a number of sliding grooves opened on the connecting groove, each of which is hinged with a main positioning block, and the main positioning block is hinged with a buckle toward one end of the joint; a number of sliding blocks are slidably matched with the outer wall of the joint, and each of the sliding blocks is hinged with an auxiliary positioning block, and the auxiliary positioning block is hinged with a buckle toward one end of the connecting groove; the auxiliary positioning block is slidably matched with the sliding groove; the buckle and the buckle are detachably connected; the main positioning block and the auxiliary positioning block are both triangular; the main positioning block has the same height as the auxiliary positioning block adjacent to it; the main positioning block and the outer wall of the connecting groove and the auxiliary positioning block and the outer wall of the joint have an inclination angle of 3° to 5° in the initial state.

[0008] The technical principles of the above scheme are as follows:

[0009] During the assembly process of the beam and the column, when the beam and the column are slightly connected, the auxiliary positioning block is first inserted into the slide groove. At this time, the beam is pushed close to the column, so that the auxiliary positioning block approaches the main positioning block along the slide groove; because the main positioning block and the auxiliary positioning block adjacent to it have the same height, when the auxiliary positioning block approaches the main positioning block along the slide groove, their ends will contact and squeeze each other.

[0010] When the end of the main positioning block and the end of the auxiliary positioning block contact, the buckle will be inserted into the connecting buckle to make the two engage. At this time, the crossbeam is kept pushed close to the column, so that the auxiliary positioning block continues to approach the main positioning block. Since the main positioning block is hinged to the slide groove, the auxiliary positioning block is hinged to the outer side wall of the joint, the main positioning block and the auxiliary positioning block are hinged to the connecting buckle and the buckle respectively. Therefore, when the buckle is inserted into the connecting buckle and engages, when the auxiliary positioning block continues to approach the main positioning block, the triangular main positioning block and the auxiliary positioning block will rotate upward and fit together due to mutual extrusion and the limiting effect of the buckle and the connecting buckle; when all adjacent main positioning blocks and auxiliary positioning blocks are rotated and fitted, it means that the crossbeam and the column are docked; after the docking is completed, the operator fixes the main positioning block and the auxiliary positioning block.

[0011] During the auxiliary positioning process, the docking components and fixing components also simultaneously complete the docking and fixing of the beams and columns.

[0012] The above scheme has the following beneficial effects:

[0013] 1. The present invention enables the assembly of the beam and the column to be carried out quickly and stably through the design of the main positioning block and the auxiliary positioning block. When the beam and the column are in a relatively fine docking, it is only necessary to put each auxiliary positioning block into the adjacent slide groove to provide a basic moving trajectory for the assembly of the beam and the column, and then align the auxiliary positioning block with the adjacent main positioning block to provide a relatively accurate moving distance and moving end point for the assembly of the beam and the column; and then through the rotation and fitting of each main positioning block and the auxiliary positioning block, the operator can intuitively observe whether the docking is completed, thereby effectively prompting the operator whether the docking needs to continue.

[0014] 2. The present invention can effectively position the beam and the column through the design of the main positioning block and the auxiliary positioning block, thereby assisting the docking assembly and the fixing assembly to dock and fix the beam and the column. In addition, the present invention can position, dock and fix the beam and the column simultaneously and synchronously through the design of the main positioning block and the auxiliary positioning block, further shortening the assembly time and improving the assembly efficiency.

[0015] 3. In the present invention, after the crossbeam and the column are butt-jointed, the operator can fix the main positioning block and the auxiliary positioning block to improve the connection stability of the joint and the connection groove, thereby improving the connection stability of the crossbeam and the column. After the main positioning block and the auxiliary positioning block are fixed, a triangular fixed structure will be actively generated between the joint and the connection groove. Compared with the prior art that only connects by butt-jointing, it can better assist the connection of the crossbeam and the column, so that the connection point has better stability.

[0016] Furthermore, the fixing assembly includes a plurality of connecting rods, one end of each connecting rod is fixedly connected to a shell, a sliding rod is slidably fitted inside the shell, and a tension spring is fixedly connected between the sliding rod and the shell; a semicircular locking block is fixedly connected to one end of the sliding rod away from the shell, and a limiting block is fixedly connected to one end of the shell away from the connecting rod, and the locking block and the limiting block are rotatably fitted together; the connecting rod in the fixing assembly located in the connecting groove is fixedly connected to the inner side wall of the connecting groove; the connecting rod in the fixing assembly located in the joint is fixedly connected to the inner side wall of the joint; the shell in the connecting groove and the shell in the joint are both centrally symmetrical.

[0017] Beneficial effect: before the assembly of the beam and the column, due to the limitation of the tension spring, the slide bar and the locking block are in the initial state and remain tilted; during the assembly process of the beam and the column, since the outer shell in the connecting groove and the outer shell in the joint are both centered and symmetrical, when the locking block and the locking block approach each other, due to the rotation cooperation between the locking block and the limit block, the locking blocks will rotate together between the limit blocks, and the limit blocks on both sides will respectively squeeze the locking blocks on the opposite side, so that the locking blocks remain horizontal, and the locking blocks on both sides form a sphere and gradually enter the spherical space formed by the limit blocks on both sides; in this process, since the locking block and the slide bar are fixedly connected, the locking block will drive the slide bar to rotate and pull the tension spring, and the tension spring is stretched under force.

[0018] After entering this space, since the locking block loses the horizontal limit of the limit block, the tension spring will immediately pull the slide bar back to its original position, causing the locking block to rotate, and the bottom of the locking block will resume its inclination. Since only the horizontal locking block can pass through the spherical space formed by the limit blocks on both sides, the locking block is now stably fixed in the spherical space and cannot move. After multiple sets of shells are docked, stable fixation of the beams and columns can be achieved.

[0019] Furthermore, the docking assembly includes a central column and a plurality of docking rods, the central column and the docking rods are fixedly connected to the inner side wall of the connection groove, and a plurality of slots for inserting the central column and the docking rods are opened in the joint.

[0020] Beneficial effect: When the auxiliary positioning blocks all enter the adjacent sliding grooves, the central column will also enter the corresponding slots, and the remaining docking rods will also enter the corresponding slots, so that the crossbeam can be smoothly positioned and installed with the column.

[0021] Furthermore, a plurality of triangular support blocks are fixedly connected to the connection points between the connection groove and the column, the planes adjacent to the connection groove and the support blocks are fixedly connected to the connection groove, and the planes adjacent to the support blocks and the column are fixedly connected to the column.

[0022] Beneficial effect: Since the triangle has stability, several triangular support blocks are fixedly connected at the connection between the slot and the column, which can significantly improve the stability of the beam-column node when subjected to force and prevent structural damage caused by uneven or excessive force.

[0023] Furthermore, the joints, troughs, center columns and docking rods are all made by mixing recycled coarse aggregate, recycled fine aggregate, fly ash, slag powder, sodium silicate and sodium hydroxide in a material ratio of 4-7:2-3:2-3:1-2:1-2.

[0024] Beneficial effects: Among the raw materials used, recycled coarse aggregate and recycled fine aggregate come from the sorting, crushing and screening of waste concrete, which not only reduces the accumulation of construction waste, but also realizes the recycling of resources. Fly ash and slag powder, as industrial by-products, also realize the recycling of resources. Sodium silicate and sodium hydroxide, as alkali activators, can activate the active components in fly ash and slag powder to form geopolymers, thereby improving the mechanical properties and durability of concrete.

[0025] Furthermore, bacillus and calcium lactate are added to the joint, the connection groove, the central column and the docking rod during the preparation process.

[0026] Beneficial effects: When cracks appear in joints, grooves, center columns and butt rods in the future, Bacillus will come into contact with moisture and air in the environment, thereby reacting with calcium lactate to produce calcium carbonate; the calcium carbonate will fill, adhere to and repair the cracks, thereby achieving a certain degree of self-repair of the beam-column node.

[0027] Furthermore, the butt joint rods have different lengths, and the groove depths are all the same as the lengths of the adjacent butt joint rods.

[0028] Beneficial effect: By using docking rods of different lengths and slot depths, when the beam is docked with the column, it is only necessary to align the longest docking rod first, and then slide the remaining docking rods into the corresponding slots, which reduces the difficulty of docking operations and improves operational efficiency.

[0029] Furthermore, the main positioning block and the auxiliary positioning block both include a bottom plate, one side of the bottom plate is fixedly connected to a vertical plate, and a plurality of triangular plates are fixedly connected between the bottom plate and the vertical plate.

[0030] Beneficial effect: Through the design of several triangular plates and utilizing the principle of stability of triangles, the stability and bearing capacity of the main positioning block and the auxiliary positioning block are improved, thereby improving the positioning stability and connection stability of the beams and columns.

[0031] Furthermore, the central column is in any shape of a triangle, a rectangle or a hexagon.

[0032] Beneficial effect: Triangle, rectangle or hexagon all have good stability, so the central column is in any shape of triangle, rectangle or hexagon, which not only facilitates connection but also improves the stability of the beam-column node.

[0033] Furthermore, the end of the limiting block away from the locking block is tapered.

[0034] Beneficial effect: the limit block can correct the existing deviation during the docking process and make the docking smoother.

[0035] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The following is further described in detail through specific implementation methods:

[0042] Embodiment 1:

[0043] As attached Figure 1-Figure 4 As shown: a recycled geopolymer concrete beam-column node structure with self-repairing function, including columns and beams, a plurality of joint grooves 1 are cast with cement on the columns, joints 3 are cast with cement at both ends of the beams, and the joint grooves 1 are provided with a docking component for beam-column docking, a fixing component for fixing the position of the beam and column, and a positioning auxiliary component for assisting the beam-column docking.

[0044] The positioning auxiliary component includes a plurality of slide grooves on the connection groove 1, each of which is hinged with a main positioning block 2, and the main positioning block 2 is hinged with a buckle 201 at one end facing the joint 3; the outer wall of the joint 3 is slidably matched with a plurality of sliding blocks 402, each of which is hinged with a secondary positioning block 4, and the secondary positioning block 4 is hinged with a buckle 401 at one end facing the connection groove 1; the secondary positioning block 4 is slidably matched with the slide groove; the buckle 201 and the buckle 401 are detachably connected; the main positioning block 2 and the secondary positioning block 4 are both triangular; the main positioning block 2 has the same height as the adjacent secondary positioning block 4. The main positioning block and the outer wall of the connection groove and the secondary positioning block and the outer wall of the joint have an inclination angle of 3° to 5° in the initial state. This inclination angle can ensure that when the main positioning block 2 is combined with the auxiliary positioning block 4 adjacent to it, the main positioning block 2 and the auxiliary positioning block 4 are both flipped outward, and the two are combined to form a triangular fixed structure; according to actual needs, threaded holes can be opened on the contact surfaces of the main positioning block 2 and the auxiliary positioning block 4 after they are combined, and fastening bolts can be installed through the threaded holes, so that the stability of the triangular fixed structure formed by the combination of the two can be reinforced.

[0045] The fixing assembly includes a plurality of connecting rods 8, one end of each of the connecting rods 8 is bolted and fixedly connected to a shell 9, a sliding rod 11 is slidably fitted inside the shell 9, and a tension spring 10 is bolted and fixedly connected between the sliding rod 11 and the shell 9; a semicircular locking block 12 is bolted and fixedly connected to the end of the sliding rod 11 away from the shell 9, and a limiting block 13 is bolted and fixedly connected to the end of the shell 9 away from the connecting rod 8, and the locking block 12 and the limiting block 13 are rotatably fitted together; the connecting rod 8 in the fixing assembly located in the connecting groove 1 is bolted and fixedly connected to the inner side wall of the connecting groove 1; the connecting rod 8 in the fixing assembly located in the joint 3 is bolted and fixedly connected to the inner side wall of the joint 3; the shell 9 in the connecting groove 1 and the shell 9 in the joint 3 are both centrally symmetrical.

[0046] The docking assembly includes a center column 5 and a plurality of docking rods 6. The center column 5 and the docking rods 6 are bolted and fixed to the inner wall of the connection groove 1. The joint 3 is provided with a plurality of slots for inserting the center column 5 and the docking rods 6.

[0047] The specific implementation process is as follows:

[0048] by Figure 1 For example, during the assembly of the beam and the column, when the beam and the column are slightly connected, the secondary positioning block 4 is first inserted into the slide groove, and the beam is pushed close to the column at this time, so that the secondary positioning block 4 approaches the main positioning block 2 along the slide groove; since the main positioning block 2 is at the same height as the secondary positioning block 4 adjacent to it, when the secondary positioning block 4 approaches the main positioning block 2 along the slide groove, their ends will contact each other, and the slider 402 will slide backward due to the obstruction of the main positioning block 2 until it slides to the maximum sliding distance. At this time, the beam and the column are connected, and since the slider 402 is limited by the connection groove, the secondary positioning block 4 and the main positioning block 2 are squeezed against each other; and since both have a 5° inclination angle in the initial state, the two will rotate upward and fit together after being squeezed against each other.

[0049] During this process, when the end of the main positioning block 2 and the end of the auxiliary positioning block 4 contact, the buckle 401 will be inserted into the buckle 201 to make the two engage. At this time, the crossbeam is kept pushed close to the column, so that the auxiliary positioning block 4 continues to approach the main positioning block 2. Since the main positioning block 2 is hinged to the slide groove, the auxiliary positioning block 4 is hinged to the outer wall of the joint 3, and the main positioning block 2 and the auxiliary positioning block 4 are respectively hinged to the buckle 201 and the buckle 401; therefore, when the buckle 401 is inserted into the buckle 201 and engaged, the auxiliary positioning block 4 continues to approach the main positioning block 2. At this time, the triangular main positioning block 2 and the auxiliary positioning block 4 will rotate upward and fit together due to the mutual squeezing and the limiting effect of the buckle 401 and the connecting buckle 201; when all adjacent main positioning blocks 2 and auxiliary positioning blocks 4 are rotated and fitted, it represents that the docking of the beam and the column is completed; after the docking is completed, the operator fixes the main positioning block 2 and the auxiliary positioning block 4 with bolts to further improve the connection stability of the joint 3 and the connecting groove 1, thereby improving the connection stability of the beam and the column.

[0050] If the auxiliary positioning block 4 is not aligned with the slide groove, the sliding block 402 will slide at the beginning of the docking, and the operator can immediately observe the deviation of the docking. When the docking is accurate, the sliding block 402 will only start to slide after the auxiliary positioning block 4 contacts the main positioning block 2; through such a design, the operator's operability is further improved.

[0051] During the auxiliary positioning process, since the crossbeams and columns have determined the assembly movement trajectory of the crossbeams and columns by placing each auxiliary positioning block 4 into the adjacent slide grooves, when the auxiliary positioning blocks 4 enter the adjacent slide grooves, the center column 5 will also enter the corresponding slots synchronously, and the remaining docking rods 6 will also enter the corresponding slots synchronously, so that the crossbeams can be smoothly positioned and installed with the columns.

[0052] by Figure 4 For example, before the assembly of the crossbeam and the column, due to the limiting of the tension spring 10, the slide bar 11 and the locking block 12 are in the initial state and remain tilted; during the assembly process of the crossbeam and the column, since the outer shell 9 in the connecting groove 1 and the outer shell 9 in the joint 3 are both centered and symmetrical, when the locking block 12 approaches each other, due to the rotation cooperation between the locking block 12 and the limiting block 13, the locking block 12 will rotate together between the limiting blocks 13, and the limiting blocks 13 on both sides will respectively squeeze the locking block 12 on the opposite side, so that the locking block 12 remains horizontal, and the locking blocks 12 on both sides form a sphere and gradually enter the spherical space formed by the limiting blocks 13 on both sides; in this process, since the locking block 12 and the slide bar 11 are fixedly connected, the locking block 12 will drive the slide bar 11 to rotate and pull the tension spring 10, and the tension spring 10 is stretched under force.

[0053] by Figure 3 For example, when the locking block 12 completely enters the spherical space, since the locking block 12 loses the horizontal limit of the limit block 13, the tension spring 10 will immediately pull the slide bar 11 back to its original position, causing the locking block 12 to rotate. At this time, the bottom of the locking block 12 resumes its tilt; since only the horizontal locking block 12 can pass through the spherical space formed by the limit blocks 13 on both sides, the locking block 12 is now stably fixed in the spherical space and cannot move; after multiple groups of shells 9 are docked, stable fixation of the beams and columns can be achieved.

[0054] The present invention enables the assembly of the beam and the column to be carried out quickly and stably through the design of the main positioning block 2 and the auxiliary positioning block 4. When the beam and the column are in a relatively fine docking, it is only necessary to put each auxiliary positioning block 4 into the adjacent chute to provide a basic moving track for the assembly of the beam and the column, and then align the auxiliary positioning block 4 with the adjacent main positioning block 2 to provide a relatively accurate moving distance and moving end point for the assembly of the beam and the column; and then the rotation and fitting of each main positioning block 2 and the auxiliary positioning block 4 is completed, and the operator can intuitively observe whether the docking is completed, thereby effectively prompting the operator whether the docking needs to continue.

[0055] The present invention can effectively position the beam and the column through the design of the main positioning block 2 and the auxiliary positioning block 4, thereby assisting the docking assembly and the fixing assembly to dock and fix the beam and the column. In addition, the present invention can position, dock and fix the beam and the column simultaneously and synchronously through the design of the main positioning block 2 and the auxiliary positioning block 4, further shortening the assembly time and improving the assembly efficiency.

[0056] After the main positioning block 2 and the auxiliary positioning block 4 are fixed, a triangular fixed structure will be actively generated between the joint 1 and the connection groove 3. Compared with the prior art that only connects by docking, it can better assist the connection between the beam and the column, making the connection point have better stability.

[0057] Embodiment 2:

[0058] As attached Figure 1-Figure 2 As shown: Different from the above embodiment, the connection between the connection slot 1 and the column is fixedly connected with a plurality of triangular support blocks 7 by bolts. The plane adjacent to the connection slot 1 of the support block 7 is fixedly connected with the connection slot 1 by bolts, and the plane adjacent to the support block 7 and the column is fixedly connected with the column by bolts.

[0059] The specific implementation process is as follows: Since the triangle has stability, a number of triangular support blocks 7 are bolted and fixed at the connection between the slot 1 and the column, which can significantly improve the stability of the beam-column node when subjected to force and prevent structural damage caused by uneven or excessive force.

[0060] Embodiment 3:

[0061] As attached Figure 1-Figure 2 As shown: Different from the above-mentioned embodiments, the joint 3, the connection groove 1, the center column 5 and the docking rod 6 are all made of recycled coarse aggregate, recycled fine aggregate, fly ash, slag powder, sodium silicate and sodium hydroxide in a material ratio of 4-7:2-3:2-3:1-2:1-2.

[0062] The specific implementation process is as follows: Among the raw materials used, recycled coarse aggregate and recycled fine aggregate come from the sorting, crushing and screening of waste concrete, which not only reduces the accumulation of construction waste, but also realizes the recycling of resources. Fly ash and slag powder, as industrial by-products, also realize the recycling of resources. Sodium silicate and sodium hydroxide, as alkali activators, can activate the active components in fly ash and slag powder to form geopolymers, thereby improving the mechanical properties and durability of concrete.

[0063] Embodiment 4:

[0064] As attached Figure 1-Figure 2 As shown: Different from the above-mentioned embodiment, Bacillus and calcium lactate are added to the joint 3, the connection groove 1, the central column 5 and the docking rod 6 during the preparation process.

[0065] The specific implementation process is as follows: when cracks appear in the joint 3, the groove 1, the central column 5 and the docking rod 6 in the future, the Bacillus will come into contact with moisture and air in the environment, thereby reacting with calcium lactate to produce calcium carbonate; the calcium carbonate will fill, adhere to and repair the cracks, thereby achieving a certain degree of self-repair of the beam-column node.

[0066] Embodiment 5:

[0067] As attached Figure 1-Figure 2 As shown in the figure: Different from the above-mentioned embodiment, the docking rods 6 have different lengths, and the groove depths are the same as the lengths of the adjacent docking rods 6.

[0068] The specific implementation process is as follows: using different lengths of docking rods 6 and groove depths, when the beam is docked with the column, it is only necessary to prioritize the longest docking rod 6, and then the remaining docking rods 6 can be slid into the corresponding grooves, reducing the difficulty of docking operations and improving operational efficiency.

[0069] Embodiment 6:

[0070] As attached Figure 1-Figure 2 As shown: Different from the above embodiments, the main positioning block 2 and the auxiliary positioning block 4 both include a bottom plate, one side of the bottom plate is fixedly connected with a vertical plate by bolts, and a plurality of triangular plates are fixedly connected with bolts between the bottom plate and the vertical plate.

[0071] The specific implementation process is as follows: through the design of several triangular plates, the stability and bearing capacity of the main positioning block 2 and the auxiliary positioning block 4 are improved by utilizing the principle that the triangle has stability, thereby improving the positioning stability and connection stability of the beam and the column.

[0072] Embodiment 7:

[0073] As attached Figure 3-Figure 4 As shown in the figure, different from the above-mentioned embodiment, the end of the limiting block 13 away from the locking block 12 is tapered.

[0074] The specific implementation process is as follows: the conical limit block 13 enables the limit block 13 to correct the existing deviation during the docking process and make the docking smoother.

[0075] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
