Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a prefabricated steel structure reinforcement component for building construction. Background Technology

[0002] In the field of building construction, steel structures are widely used due to their advantages such as high strength, light weight, and fast construction speed. For T-shaped connection nodes composed of columns and beams, especially when the beams are made of two I-beams joined together and the joint is located directly above the top of the column, existing technologies typically employ two methods to reinforce the connection between the column and the beam: one is to weld directly at the joint between the column I-beam and the beam I-beam; the other is to use multiple L-shaped angle iron reinforcements on the four sides of the column, and then use a large number of bolts to connect the left and right beam I-beams to the column.

[0003] However, all of the aforementioned existing technologies have significant drawbacks. Welded connections require high levels of skill from both the construction team and the operators, making it difficult to consistently control the welding quality on-site. Furthermore, the heat-affected zone alters the steel's material composition, generating residual stress and deformation, reducing the fatigue performance of the joint, and making subsequent adjustment and disassembly difficult. (See also...) Figure 7 While the use of multiple L-shaped angle irons and numerous bolts avoids welding issues, in actual construction, especially in high-altitude, confined, or time-sensitive environments, workers need to align and tighten numerous bolts on all four sides of the column. This operation is extremely tedious, time-consuming, and inefficient. For example, when hoisting and fixing beams at heights of tens of meters, workers must work suspended in the air for extended periods, tightening bolts on multiple reinforcement components one by one. This not only involves high labor intensity and safety risks, but even minor misalignments can lead to installation difficulties, severely impacting construction progress and the immediate stability of node connections. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is that in the prior art, the T-shaped joint between the column and the beam is fixed by welding or a large number of bolts, which has the prominent problems of difficult control of welding quality, cumbersome high-altitude installation operation and high safety risk.

[0005] The above-mentioned technical problems are solved by the following technical solution: This utility model proposes a prefabricated steel structure reinforcement component for building construction, used to connect the I-beams of the columns and the I-beams of the beams. It includes a top plate with an I-shaped slot on its lower surface for inserting and engaging with the upper end of the column I-beam, and at least one T-slot on the side of the top plate; a diagonal brace with a T-shaped foot at its end that slides and engages with the T-slot; and a horizontal plate with a third hole for connecting with the upper flange of the left and right horizontal beam I-beams.

[0006] In a preferred embodiment of the prefabricated steel structure reinforcement for building construction described in this utility model: the number of the diagonal bracing plates is four, and each diagonal bracing plate has a T-shaped foot at its end; each of the four sides of the top plate has a T-shaped groove, and each T-shaped groove corresponds to and cooperates with the T-shaped foot of one of the diagonal bracing plates.

[0007] In a preferred embodiment of the prefabricated steel structure reinforcement for building construction described in this utility model: a plurality of first holes are provided on the top plate, and the first holes penetrate the crossbeam I-beam.

[0008] In a preferred embodiment of the prefabricated steel structure reinforcement for building construction described in this utility model: multiple second holes are provided on the I-beam of the column.

[0009] In a preferred embodiment of the prefabricated steel structure reinforcement for building construction described in this utility model: the cross-section of the inclined brace is T-shaped, and its side is an isosceles trapezoid, with the upper limit side and the lower limit side on the left and right sides of the isosceles trapezoid, respectively.

[0010] In a preferred embodiment of the prefabricated steel structure reinforcement for building construction described in this utility model: two first holes are opened on one side of the lower flange of the left crossbeam I-beam, and four holes are opened on both the front and rear sides; two first holes are opened on one side of the lower flange of the right crossbeam I-beam, and four holes are opened on both the front and rear sides.

[0011] In a preferred embodiment of the prefabricated steel structure reinforcement for building construction described in this utility model: the second hole has two parallel holes on the left flange of the column I-beam, two parallel holes on the right flange, and two parallel through holes on the web.

[0012] In a preferred embodiment of the prefabricated steel structure reinforcement for building construction described in this utility model: all the first holes are located outside the upper limit edge of the inclined brace, and all the second holes are located outside the lower limit edge of the inclined brace.

[0013] In a preferred embodiment of the prefabricated steel structure reinforcement for building construction described in this utility model: the third hole is provided in two rows on the left crossbeam I-beam, with three holes in each row; and in two rows on the right crossbeam I-beam, with three holes in each row.

[0014] In a preferred embodiment of the prefabricated steel structure reinforcement for building construction described in this utility model: the T-slots are paired and arranged in a cross shape, wherein the I-shaped slot is connected to the two T-slots located in the length direction of the top plate.

[0015] The beneficial effects of this utility model are as follows: The I-shaped slot at the bottom of the top plate can be directly and accurately fitted onto the top of the I-beam of the column, instantly completing the vertical positioning and support of the core component, avoiding the initial difficulty of roughly aligning multiple connecting parts one by one in the traditional method. Subsequently, the four diagonal bracing plates, through the cooperation of their T-shaped feet at the ends and the T-shaped slots pre-set on the side of the top plate, can be easily guided into the preset position by simply sliding horizontally, and are finally naturally limited by the column body. This process replaces the arduous operation of simultaneously holding and aligning multiple independent L-shaped angle irons and bolt holes at high altitude in the traditional solution. Finally, the horizontal plate is locked in one go by multiple rows of bolts by simply covering the upper flanges of the left and right horizontal beams. The entire installation process is simplified from "three-dimensional multi-point fine alignment" to a continuous action of "one insertion, two sliding, three covering", with clear steps and significantly reduced manpower and time required, making it particularly suitable for high-risk and high-efficiency construction scenarios.

[0016] The diagonal bracing plates slide to a tight fit with the column flanges or webs, forming a direct surface contact force transmission area. This efficiently transfers the beam load to the column core in the form of pressure or tension, resulting in a short and direct force transmission path. Key connection points are ultimately secured using bolt groups. These bolt groups connecting the top plate, beams, and upper diagonal bracing plates, along with long bolts penetrating the web and simultaneously tightening the left and right diagonal bracing plates, together form a mechanical locking network to prevent component loosening. Specifically, the beams, through their matrix-arranged bolt groups, connect the upper flanges of the left and right beams as a whole. This not only enhances the overall integrity of the beams but also, in conjunction with the top plate, constrains the upper flanges, effectively preventing local instability and relative displacement of the beams. The T-shaped feet and T-slots, while withstanding vertical shear forces, complement the aforementioned bolt locking mechanism, providing dual protection against shear and pull-out, thereby significantly improving node stiffness and load-bearing capacity.

[0032] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0033] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0034] Reference Figures 1-6 This embodiment provides a prefabricated steel structure reinforcement component for building construction, used to connect the column I-beam 4 and the crossbeam I-beam 5. It includes a top plate 1, the lower surface of which is provided with an I-shaped slot 11 for inserting and engaging with the upper end of the column I-beam 4, and the side of the top plate 1 is provided with at least one T-slot 12; a diagonal brace 2, the end of which is provided with a T-shaped foot 21 for sliding engagement with the T-slot 12; and a cross plate 3 with a third hole 31 for connecting with the upper flange 54 of the left and right crossbeam I-beams 52.

[0035] This prefabricated reinforcement system mainly consists of three components: a top plate 1, a diagonal brace 2, and a horizontal plate 3. These three components work together to achieve a fast and reliable prefabricated connection. The top plate 1, serving as the central support and transition component for the connection node, has an I-shaped groove 11 machined on its lower surface that precisely matches the cross-sectional shape of the upper end of the I-beam 4. During installation, this I-shaped groove 11 can be directly fitted onto the top of the column from top to bottom, achieving rapid centering and initial positioning of the component and bearing the vertical pressure from the superstructure. Furthermore, at least one T-slot 12 is provided on the side facade of the top plate 1, serving as a guide and connection interface for the subsequent installation of the diagonal brace 2.

[0036] The diagonal brace 2 is a key component for transmitting horizontal forces and enhancing node stiffness. One end of it has a T-shaped foot 21 that mates with the T-slot 12 on the side of the top plate 1. By embedding the T-shaped foot 21 into the T-slot 12 and sliding it along the slot, the diagonal brace 2 can be easily guided to a preset position, allowing it to tightly abut against the flange or web 44 of the I-beam 4 of the column, forming effective surface contact support and transferring part of the load from the crossbeam to the column via a more optimized path. The horizontal plate 3 is a component used to integrate and lock the upper crossbeam. It has multiple sets of third holes 31 pre-drilled on its surface. During installation, the horizontal plate 3 covers the upper flanges 54 of the left and right I-beams 5, and is connected and secured by bolts 6 passing through these third holes 31 and corresponding holes on the upper flanges 54 of the crossbeams. This not only connects the left and right crossbeams into a whole, enhancing the integrity and stability of the crossbeam system, but also effectively constrains the upper flanges 54 of the crossbeams, allowing them to participate in the node's load-bearing capacity. The top plate 1, the diagonal bracing plate 2, and the horizontal plate 3 work together in the above manner to form a complete, robust, and easy-to-install prefabricated steel structure node reinforcement system.

[0037] There are four diagonal bracing plates 2, and each diagonal bracing plate 2 has a T-shaped foot 21 at its end; each of the four sides of the top plate 1 has a T-shaped groove 12, and each T-shaped groove 12 corresponds to and cooperates with the T-shaped foot 21 of a diagonal bracing plate 2.

[0038] Specifically, this prefabricated reinforcement typically comprises four independent diagonal bracing plates 2. Each diagonal bracing plate 2 has a T-shaped foot 21 of a specific structure integrally provided or fixedly connected at its end for connection with the top plate 1. Correspondingly, the top plate 1 is typically designed as a rectangular body, with a T-slot 12 machined on each of its four sides (front, rear, left, and right). The dimensions and orientation of each T-slot 12 are configured to precisely accommodate and guide the T-shaped foot 21 on one of the diagonal bracing plates 2 to slide in a predetermined direction. Therefore, during assembly, the four diagonal bracing plates 2 can be quickly positioned and initially connected from four directions by engaging their T-shaped feet 21 with the corresponding T-slots 12 on the sides of the top plate 1, thereby forming a stable and reinforced structure supported from four sides around the I-beam column 4.

[0039] Among them, the T-shaped grooves 12 are paired and distributed in a cross shape, and the I-shaped groove 11 is connected to the two T-shaped grooves 12 located in the length direction of the top plate 1.

[0040] The four T-slots 12 on the top plate 1 are symmetrically arranged in pairs, thus forming a cross-shaped distribution pattern on the four sides of the top plate 1. This arrangement allows the diagonal bracing plates 2 to provide uniform support and reinforcement to the nodes from four orthogonal directions. Specifically, the I-shaped slot 11 opened on the lower surface of the top plate 1 is usually aligned with the extension direction of one of the pairs of opposing T-shaped slots 12 on the top plate 1 (i.e., the slots opened on the two sides of the top plate 1 along its length). More importantly, the opening of the I-shaped slot 11 extends upward on the lower surface of the top plate 1, and its internal space is interconnected with the internal channels of the two T-shaped slots 12. This interconnected design allows the T-shaped feet 21 of the diagonal bracing plates 2 used to support the web 44 of the column I-beam 4 to act more directly and closely on the area of ​​the web 44 of the column I-beam 4 after being inserted into the T-shaped slot 12 and sliding inward. This optimizes the force transmission path and may provide visual or tactile convenience for installation alignment.

[0041] The cross-section of the diagonal brace 2 is T-shaped, and its side is an isosceles trapezoid. The left and right sides of the isosceles trapezoid are the upper limit edge 22 and the lower limit edge 23, respectively. All the first holes 13 are located outside the upper limit edge 22 of the diagonal brace 2, and all the second holes 41 are located outside the lower limit edge 23 of the diagonal brace 2.

[0042] The overall cross-section of the bracing plate 2 is T-shaped, mainly composed of its T-shaped feet 21 at the ends for engaging with the T-slots 12 of the top plate 1 and its main body plate. Viewed from the side, the side profile of the main body plate of the bracing plate 2 is an isosceles trapezoid. The two parallel bases of this isosceles trapezoid are defined as the upper limit edge 22 and the lower limit edge 23, respectively. The upper limit edge 22 is close to the top plate 1 and the crossbeam I-beam 5, and after installation, it fits against the lower flange 53 of the crossbeam and the top plate 1; the lower limit edge 23 is close to the column I-beam 4, and after installation, it fits against the flange or web 44 surface of the column. All first holes 13 for connecting to the crossbeam and the top plate 1 are located in the outer region of the main body of the bracing plate 2, close to and parallel to the upper limit edge 22. Correspondingly, all second holes 41 for connecting to the column I-beam 4 are located in the outer region of the main body of the bracing plate 2, close to and parallel to the lower limit edge 23. This design, which explicitly positions the first hole 13 and the second hole 41 as connection holes on the outer side of the upper and lower limiting edges 23, ensures that the clamping force generated when the bolt 6 is tightened directly acts on the key load-bearing area of ​​the brace plate 2, and also blocks the outer side of the upper end of the brace plate 2 and forms a barrier on the outer side of the lower end, thereby preventing the outward movement of the brace plate 2 and ensuring that the brace plate 2 is firmly fixed. At the same time, it makes the force transmission path more direct and clear. This design makes the connection holes with different functions clearly distinguishable in space, which is convenient for precise processing during manufacturing and quick identification and alignment during on-site installation. It effectively prevents misassembly and improves the orderliness and reliability of the entire reinforcement node connection.

[0043] Multiple first holes 13 are provided on the top plate 1, and the first holes 13 penetrate the crossbeam I-beam 5. There are two first holes 13 on one side of the lower flange 53 of the left crossbeam I-beam 51, and a total of four on both the front and rear sides; there are two first holes 13 on one side of the lower flange 53 of the right crossbeam I-beam 52, and a total of four on both the front and rear sides.

[0044] To achieve a final rigid connection between the diagonal bracing plate 2, the crossbeam, and the top plate 1, multiple first holes 13 are pre-drilled in the top plate 1 for bolts 6 to pass through. The positions of these first holes 13 are specially designed to align with corresponding holes on the lower flange 53 of the crossbeam I-beam 5 during installation. Specifically, two first holes 13 are spaced apart along the width direction (i.e., the front-to-back direction) of the crossbeam in the area of ​​the top plate 1 corresponding to the lower flange 53 of the left crossbeam I-beam 51; similarly, two first holes 13 are also drilled in the area of ​​the top plate 1 corresponding to the lower flange 53 of the right crossbeam I-beam 52. After the left and right crossbeams are in place, the two first holes 13 on each side are paired along the span direction (i.e., the left-to-right direction) of the crossbeam. Therefore, at the entire node, there are a total of four such first holes 13 on both the front and back sides, used to connect the top plate 1 and the crossbeam and simultaneously fix the upper diagonal bracing plate 2. The function of these first holes 13 is to allow high-strength bolts 6 to pass through the corresponding holes on the lower flange 53 of the crossbeam, the top plate 1, and the diagonal brace 2 from top to bottom or from bottom to top after the diagonal brace 2 is in place. By tightening the bolts 6 and nuts, the left or right crossbeam, the top plate 1, and the corresponding upper diagonal brace 2 are locked together at once, which greatly simplifies the assembly process and ensures the integrity and reliability of the connection.

[0045] Multiple second holes 41 are provided on the column I-beam 4. Two second holes 41 are provided side by side on the left flange 42 of the column I-beam 4, two are provided side by side on the right flange 43, and two are provided side by side through the web plate 44.

[0046] To securely connect the diagonal bracing plate 2 to the column I-beam 4, multiple second holes 41 are drilled on-site at corresponding positions on the column I-beam 4. The positions of these second holes 41 are determined based on the final mating position of the diagonal bracing plate 2: On the upper surface of the left flange 42 of the column I-beam 4, two second holes 41 are spaced apart along the flange width direction (i.e., the front-to-back direction) to align with the corresponding holes on the lower part of the left diagonal bracing plate 2 and connect them via bolts 6; On the lower surface of the right flange 43, two parallel second holes 41 are also drilled to connect the right diagonal bracing plate 2. In addition, on the web 44 of the column I-beam 4, at positions corresponding to the installation height of the left and right diagonal bracing plates 2, two second holes 41 are drilled vertically through the thickness direction of the web 44. These two through holes allow a long bolt 6 to pass sequentially through one diagonal bracing plate 2, the web 44, and the other diagonal bracing plate 2, thereby simultaneously tightening and fixing the diagonal bracing plates 2 on both sides of the web 44. All the second holes 41 are precisely matched with the holes on the corresponding bracing plates 2, ensuring that the bracing plates 2 can be tightly pressed against the corresponding surfaces of the I-beams 4 during final tightening, forming a stable force transmission connection.

[0047] The third hole 31 has two rows of three holes each on the left crossbeam I-beam 51; and two rows of three holes each on the right crossbeam I-beam 52.

[0048] To securely connect the horizontal plate 3 to the left and right crossbeams 52 into a cohesive whole, regularly arranged third holes 31 are provided on the upper flange 54 of the crossbeams 5. Specifically, on the upper flange 54 of the left-side crossbeam 5, two rows of connecting holes are arranged at intervals along its width direction (i.e., the front-to-back direction), each row containing three third holes 31 arranged along the length direction of the crossbeam flange (i.e., the left-to-right direction). Similarly, on the upper flange 54 of the right-side crossbeam 5, two rows of third holes 31 are also provided in the same layout, each row containing three third holes 31. The positions of these third holes 31 are aligned with the corresponding connecting holes on the horizontal plate 3. After the horizontal plate 3 is placed over the left and right horizontal beams, the high-strength bolts 6 can be fastened by passing through the aligned third hole 31 and the hole on the horizontal plate 3. This matrix layout with two rows on each side and three holes in each row provides multiple reliable connection points, which can effectively connect the two independent horizontal beams I-beams 5 into one unit through the horizontal plate 3. This significantly enhances the overall rigidity and torsional resistance of the horizontal beam assembly at the node, prevents the misalignment of a single horizontal beam or the instability of the upper flange 54 due to load, and ensures the flatness and stability of the upper structure.

[0049] Detailed workflow and installation steps:

[0050] Step 1: Positioning the top plate 1. Whether prefabricated in the factory or on-site, first align the I-shaped slot 11 on the lower surface of the top plate 1 with the upper end of the already erected and fixed column I-beam 4 and place it vertically downwards, so that the top of the column is completely embedded in the slot. At this time, the top plate 1 obtains stable support, and the tight fit between the slot and the column prevents horizontal movement and rotation.

[0051] Step 2: Place the crossbeam. Hoist the two sections of I-beams (with their joints located above the top plate 1) to the upper surface of the top plate 1. The lower flange 53 of the crossbeam I-beam 5 rests directly on the upper surface of the top plate 1, completing the initial positioning.

[0052] Step 3: Install and lock the diagonal brace 2. This step is crucial for forming a rigid node.

[0053] Insert the diagonal bracing plates 2: Insert the T-shaped feet 21 of the four diagonal bracing plates 2 into the T-shaped grooves 12 entrances on the four sides of the top plate 1 from the four directions respectively.

[0054] Sliding into position: Push each bracing plate 2 inward along the T-slot 12 so that its T-shaped foot 21 slides toward the center of the node. During this process, the plate body of the bracing plate 2 gradually approaches the corresponding side of the column I-beam 4 (i.e., the left surface of the left flange 42, the right surface of the right flange 43, and the front and rear sides of the web plate 44).

[0055] Final tightening: Continue pushing the diagonal brace 2 until its inner plane is completely and tightly fitted with the corresponding side of the I-beam 4 of the column, forming a surface contact support. At this time, the diagonal brace 2 is restricted to detach in the vertical direction through the cooperation of the T-shaped foot 21 and the T-shaped groove 12, and its inward sliding position is naturally limited by the column body.

[0056] Step 4: Drill holes and tighten bolts 6. To permanently fix the position of the diagonal brace 2 and form a high-strength connection, bolts 6 need to be tightened.

[0057] Hole alignment: After the diagonal brace 2 is slid into place.

[0058] For the left diagonal brace 2 (corresponding to the left side of the left flange 42 of the column): its upper surface outer edge is flush with the lower flange 53 of the left crossbeam I-beam 51 and the corresponding position of the top plate 1; its lower surface outer edge is flush with the left flange 42 of the column I-beam 4.

[0059] For the right-side diagonal brace 2 (below the right flange 43 of the column): its upper outer edge is flush with the lower flange 53 of the right crossbeam I-beam 52 and the corresponding position of the top plate 1; its lower outer edge is flush with the right flange 43 of the column I-beam 4.

[0060] For the front and rear diagonal bracing plates 2 (corresponding to the front and rear sides of the column web 44): their inner and outer surfaces are respectively attached to the front and rear sides of the top plate 1 and the front and rear sides of the column web 44.

[0061] Bolt 6 arrangement: Through holes are formed at the corresponding positions by on-site drilling.

[0062] Left side connection: On the lower flange 53 of the left crossbeam I-beam 51 and the top plate 1, a set of first holes 13 are drilled at the two front and rear upper corners of the left diagonal brace plate 2; on the left flange 42 of the column I-beam 4, a set of second holes 41 are drilled at the two front and rear lower corners of the left diagonal brace plate 2; four sets of high-strength bolts 6 and nuts are used to pass through these holes to lock and fix the left diagonal brace plate 2 to the crossbeam, the top plate 1 and the left flange 42 of the column.

[0063] Right side connection: On the right flange 43 of the column I-beam 4, corresponding to the two front and rear upper corners of the right diagonal brace 2, drill the second hole 41; use four sets of high-strength bolts 6 and nuts to pass through the two front and rear lower corners of the right diagonal brace 2 and these second holes 41 to lock and fix the right diagonal brace 2 to the right flange 43 of the column.

[0064] Front and rear side connections: On the front and rear sides of the web plate 44 of the column I-beam 4, a set of second holes 41 in the vertical direction are drilled; on the front and rear sides of the top plate 1, corresponding to the upper part of the front and rear diagonal bracing plates 2, a set of first holes 13 are drilled; using four sets of high-strength bolts 6 and nuts, each set of bolts 6 passes sequentially through the first hole 13 of one side of the top plate 1, the diagonal bracing plate 2 of that side, the second hole 41 of the column web plate 44, and the diagonal bracing plate 2 of the other side, and is finally tightened with nuts. In this way, a single long bolt 6 can simultaneously fix the diagonal bracing plates 2 on both the left and right sides and tighten the column web plate 44.

[0065] Final locking: After tightening all bolts 6 to the specified torque, the diagonal brace 2 is firmly pressed between the column and the top plate 1 / beam. The cooperation between the T-shaped foot 21 and the T-slot 12 bears the main vertical shear force, while the bolt group 6 effectively prevents the horizontal sliding and tilting of the diagonal brace 2, and efficiently transfers the beam load to the column through the diagonal brace 2 in the form of compression or tension, forming a stable rigid connection node.

[0066] Step 5: Install and lock the horizontal plate 3.

[0067] A horizontal plate 3 is placed on the upper surface of the left and right crossbeams 51 and 52, which serve as crossbeams. Three third holes 31 are made on the left side of the horizontal plate 3 and the left crossbeam 51, and three third holes 31 are made on the right side of the horizontal plate 3 and the right crossbeam 52, for a total of twelve holes. A set of high-strength bolts 6 and nuts are installed in each hole to fix the horizontal plate 3 to the left and right crossbeams 52 and to lock the upper surface of the left and right crossbeams 52.

[0068] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
