Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a prefabricated cap beam bracket. Background Technology

[0002] like Figure 1 As shown, existing brackets mostly adopt a welded single-layer inclined leg structure 1, which makes its force transmission path unclear and prone to deformation due to local instability. At the same time, this inclined leg structure 1 also requires workers to assemble and weld it one by one at a height on the pier, which poses a risk of falling and is time-consuming and labor-intensive. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a prefabricated cap beam bracket to solve the problems of insufficient load-bearing capacity and low installation efficiency in the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A prefabricated cap beam bracket includes: a plurality of bracket units, each bracket unit including: two support components, the two support components being arranged at intervals and connected therebetween by a connecting block;

[0006] The support components include:

[0007] A vertical rod has an upper end and a lower end, and a first sliding seat is slidably provided at its lower end. The upper end and the lower end of the vertical rod are respectively installed on the pier body through two pre-embedded parts, and the two pre-embedded parts are connected by a tie rod.

[0008] A load-bearing rod is set perpendicular to the vertical rod, and one end of the rod is detachably fixed to the upper end of the vertical rod, while the other end is slidably provided with a second sliding block.

[0009] The diagonal bar connects the first slide block and the second slide block to form the first hinge point and the second hinge point respectively, and to construct a triangular support structure between the vertical bar, the load-bearing bar and the diagonal bar;

[0010] The first slide and the second slide are respectively fixed to the vertical rod and the load-bearing rod by two detachable locking members. Vertical force-bearing rods and diagonal force-bearing rods are respectively provided on the inner and outer sides of the triangular support structure. The vertical force-bearing rods and the diagonal force-bearing rods are respectively connected to different positions of the load-bearing rod and the diagonal rod.

[0011] Furthermore, the two ends of the vertical force-bearing rod are detachably connected to the load-bearing rod and the diagonal rod, respectively; and / or

[0012] The two ends of the inclined force-bearing rod are detachably connected to the load-bearing rod and the inclined rod, respectively.

[0013] Furthermore, the locking component includes a matching high-strength bolt and nut, with an anti-loosening washer provided between the bolt and the nut.

[0014] Furthermore, multiple connecting blocks are provided to connect different positions of the two supporting components.

[0015] Furthermore, the plurality of connecting blocks include at least one first connecting block connecting two of the vertical rods and at least one second connecting block connecting two of the load-bearing rods, wherein the cross-sectional shapes of the first connecting block and the second connecting block are the same or different.

[0016] Furthermore, the first connecting block includes two first horizontal ribs, two first oblique ribs, and a first vertical rib. The two first horizontal ribs are spaced apart in the vertical direction, and their ends are respectively connected to the two vertical rods. The two first oblique ribs are symmetrically arranged between the two first horizontal ribs with the first vertical rib as the axis of symmetry, so as to form a plurality of triangular support cavities.

[0018] Furthermore, an adjusting rod is provided at the end of the load-bearing rod away from the vertical rod, and the adjusting rod is detachably connected to the load-bearing rod.

[0019] Compared with existing technologies, this utility model has the following advantages: the vertical rod, load-bearing rod, and diagonal rod form a stable triangular support structure, which allows the load to be directly transferred to the pre-embedded anchor points on the pier body. At the same time, the combination of vertical and diagonal load-bearing rods forms a double-load-bearing reinforcement structure, improving local bending stiffness. Furthermore, the two triangular support components are connected by a connecting block to form a whole, and the double-layer setting can further improve structural stability and load-bearing capacity. Moreover, the bracket unit adopts a modular design, which can be assembled on the ground and then hoisted to the designated location for installation, reducing the time spent working at height, improving work efficiency, and reducing the risks of working at height. In addition, during the ground assembly process, the position of the first and second sliding blocks can be adjusted to change the angle of the diagonal brace, and locking devices can be used to secure it, so as to meet the needs of different lengths and improve the versatility of this bracket.

[0034] The present invention will be further described in detail below through specific embodiments:

[0035] In the embodiments of this utility model, such as Figure 2 , Figure 3As shown, the prefabricated cap beam bracket includes: several bracket units, each bracket unit including: two support components 2, which are spaced apart and connected by a connecting block; each support component 2 includes: a vertical rod 201, a load-bearing rod 202, and a diagonal rod 203; the vertical rod 201 has an upper end and a lower end, and its lower end is slidably provided with a first sliding seat 204; the upper end and the lower end of the vertical rod 201 are respectively installed on the pier body through two embedded parts 3, and the two embedded parts 3 are connected by a tie rod 4; the load-bearing rod 202 is set perpendicular to the vertical rod 201, and one end of it is detachably fixed to the upper end of the vertical rod 201, and the other end is slidably provided with a second sliding seat 205; the diagonal rod 203 connects the first sliding seat 204 and the second sliding seat 205 to form a first hinge point and a second hinge point respectively, and to construct a triangular support structure between the vertical rod 201, the load-bearing rod 202, and the diagonal rod 203;

[0036] The first slide block 204 and the second slide block 205 are respectively fixed to the vertical rod 201 and the load-bearing rod 202 by two detachably provided locking members 5. A vertical force-bearing rod 206 and an inclined force-bearing rod 207 are respectively provided on the inner and outer sides of the triangular support structure. The vertical force-bearing rod 206 and the inclined force-bearing rod 207 are respectively connected to different positions of the load-bearing rod 202 and the inclined rod 203.

[0037] Specifically, in this embodiment of the utility model, the bracket unit includes two support components 2 and a connecting block. The two support components 2 are arranged at intervals and are connected by the connecting block to form a whole, thereby enabling the bracket unit to form a double-layer structure and thus improving the overall load-bearing capacity of the bracket unit.

[0038] In this embodiment of the utility model, the support component 2 includes a vertical rod 201, a load-bearing rod 202, and a diagonal rod 203. The three components are connected to form a triangular support structure. On the one hand, the load can be directly transferred to the pier body, improving its local bending stiffness. On the other hand, the installation method of splicing on the ground and then hoisting can be adopted to form a modular installation, reducing the time spent working at height and improving construction efficiency. At the same time, it is also convenient to disassemble, transport, and reuse. In addition, the vertical rod 201 and the load-bearing rod 202 are respectively provided with a first slide 204 and a second slide 205. The first slide 204 and the second slide 205 can slide along the length direction of the vertical rod 201 and the load-bearing rod 202 respectively under the action of external force, so as to adjust the angle of the inclined rod 203 connecting the two slides. This not only extends the support span to the corresponding position to improve the versatility of this bracket, but also accurately matches the load application point to make it uniformly stressed. After adjusting the angle of the inclined rod 203 on the ground, the first slide 204 and the second slide 205 are fixed to the vertical rod 201 and the load-bearing rod 202 respectively using the locking member 5 to form a stable triangular support structure.

[0039] In addition, vertical force-bearing rods 206 and diagonal force-bearing rods 207 are respectively provided on the inner and outer sides of the aforementioned triangular support structure, such as... Figure 2 As shown, the vertical load-bearing bar 206 is arranged in the vertical direction, and its upper and lower ends are connected to the load-bearing bar 202 and the diagonal bar 203, respectively; similarly, the diagonal load-bearing bar 207 is arranged at an inclination, and its two ends are also connected to the load-bearing bar 202 and the diagonal bar 203, thus forming a double support system, which enhances the bending resistance of the load-bearing bar 202 and the load-bearing capacity of the auxiliary diagonal bar 203, thereby improving the local stiffness.

[0040] This embodiment uses a triangular support structure consisting of a vertical rod 201, a load-bearing rod 202, and a diagonal rod 203. This, combined with the vertical load-bearing rod 206 and the diagonal load-bearing rod 206, forms a stable dual support system, improving the load-bearing capacity of the bracket and preventing localized deformation. Furthermore, the modular design allows for assembly of all components on the ground before hoisting, reducing the time spent working at heights and improving construction efficiency. During ground assembly, the angle of the diagonal rod 203 can be adjusted, and after adjustment, it is locked in place by the locking element 5 to accommodate different cantilever lengths.

[0041] In one embodiment, to facilitate transportation and assembly of the various components, the two ends of the vertical load-bearing member 206 are detachably connected to the load-bearing member 202 and the diagonal member 203, respectively; the two ends of the diagonal load-bearing member 207 are also detachably connected to the load-bearing member 202 and the diagonal member 203, respectively. In this way, the various components can be assembled on the ground and then hoisted together, improving construction efficiency.

[0042] In one embodiment, the locking member 5 includes a mating high-strength bolt and a nut, with an anti-loosening washer provided between the bolt and the nut.

[0043] like Figure 3 As shown, in one embodiment, multiple connecting blocks are provided to connect different positions of the two support components 2. Specifically, in order to further improve the load-bearing capacity of the two support components 2, this embodiment provides multiple connecting blocks, which are respectively connected to different positions of the two support components 2.

[0044] Furthermore, such as Figure 3 As shown, the plurality of connecting blocks include at least one first connecting block 6 connecting the two vertical rods 201, and at least one second connecting block 7 connecting the two load-bearing rods 202. Thus, the first connecting block 6 and the second connecting block 7 can effectively fix the two support components 2 in both the horizontal and vertical directions, thereby improving their local bending strength. Of course, a suitable connecting block structure can be rationally selected according to actual installation needs and stress analysis; therefore, the cross-sectional shapes of the first connecting block 6 and the second connecting block 7 can be the same or different.

[0045] Preferably, such as Figure 3 As shown, the first connecting block 6 includes two first horizontal ribs 601, two first diagonal ribs 602, and a first vertical rib 603. The two first horizontal ribs 601 are spaced apart vertically, and their ends are respectively connected to the two vertical rods 201. The two first diagonal ribs 602 are symmetrically arranged between the two first horizontal ribs 601 about the first vertical rib 603 as an axis of symmetry, to form multiple triangular support cavities. In this embodiment, the two first horizontal ribs 601 arranged in parallel vertically form a rigid frame structure to resist the horizontal shear force and torsional moment of the vertical rods 201, preventing lateral instability of the support assembly 2. The arrangement of the first diagonal ribs 602 can convert the horizontal load into axial pressure or tension, avoiding moment concentration, and at the same time provide support stiffness under the action of the first vertical ribs 603. The above-mentioned rods can be constructed into triangular support cavities to eliminate stress dead angles. Of course, the integral arrangement can also be assembled and then hoisted together.

[0046] Preferably, such as Figure 4 As shown, the second connecting block 7 includes multiple second horizontal ribs 701, multiple second vertical ribs 702, and multiple second diagonal ribs 703. The multiple second horizontal ribs 701 are arranged at equal intervals, and the multiple second vertical ribs 702 are vertically connected to the multiple second horizontal ribs 701. The multiple second diagonal ribs 703 are respectively arranged between two adjacent second horizontal ribs 701 to form multiple triangular support openings. In this embodiment, the arrangement of the second horizontal ribs 701 can also form a rigid frame structure to construct a multi-layer horizontal bending resistance band. The second vertical ribs 702 provide stability to the above-mentioned steel frame structure, and the second diagonal ribs 703 can realize three-dimensional load diffusion and improve structural strength.

[0047] like Figure 5 As shown, in this embodiment, an adjusting rod 8 is provided at the end of the load-bearing rod 202 facing away from the vertical rod 201, and the adjusting rod 8 is detachably connected to the load-bearing rod 202. Specifically, when the aforementioned support assembly 2 is installed at the double-limb thin-walled pier, support assemblies 2 are installed at both piers, and the two are connected by the adjusting rod 8. Since the adjusting rod 8 is a detachable connection, an adjusting rod 8 of appropriate length can be selected during the assembly process to connect the support assembly 2 of the double-limb thin-walled pier, making the bracket flexible and applicable to various types.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
