Description

Technical Field

[0001] This application relates to the field of bridge engineering technology, and in particular to a support system for matching crossbeams. Background Technology

[0002] In bridge construction, to shorten the construction period, the bridge beams can be prefabricated in sections. That is, prefabricated box girders are first manufactured on an independent site. After the prefabricated box girders are completed, they are then erected using a bridge erecting machine to complete the bridge beam construction.

[0003] The precast box girder has a central hole running through both ends. To ensure the structural strength of the precast box girder, a transverse diaphragm can be formed in the central hole. The transverse diaphragm is equipped with external anchorages (hereinafter referred to as anchorages). During the preparation of the transverse diaphragm, due to the large weight and severe weight eccentricity of the anchorages, if the anchorages are directly installed during the binding of the reinforcing steel skeleton (or reinforcing cage) of the transverse diaphragm, it will cause unnecessary loss of manpower and material resources, prolong the construction period of the transverse diaphragm, and also lead to a higher construction risk factor and safety hazards. Utility Model Content

[0004] In view of this, the purpose of this application is to propose a support system for matching crossbeams, so as to at least partially solve the problem of construction inconvenience caused by directly installing anchors when binding the steel reinforcement structure of crossbeams.

[0005] To achieve the above objectives, this application provides a support system for a matching crossbeam, comprising: a frame including a first end face and a second end face disposed opposite to each other, wherein a positioning through hole is formed in the frame body through the first end face and the second end face; and an anchor member detachably connected to the positioning through hole, wherein the center of gravity of the anchor member is close to the center point of the anchor member.

[0006] Optionally, the frame includes multiple vertical steel sections and horizontal steel sections, with the multiple vertical steel sections spaced apart and adjacent vertical steel sections connected by the horizontal steel sections; the vertical steel sections and the horizontal steel sections define the positioning through holes.

[0007] Optionally, the transverse steel section includes supporting steel sections located on the first end face and the second end face respectively, and the two ends of the anchor member extend out of the first end face and the second end face respectively, with the supporting steel section supporting the anchor member.

[0008] Optionally, the transverse steel section further includes a connecting steel section located between the first end face and the second end face, wherein the size of the connecting steel section is smaller than the size of the supporting steel section.

[0009] Optionally, both the vertical steel section and the horizontal steel section are channel steel.

[0010] Optionally, the slot of the supporting steel is set horizontally.

[0011] Optionally, the vertical steel section is welded to the horizontal steel section or connected by fasteners.

[0012] Optionally, the anchor component has an internal cavity.

[0013] Optionally, the anchor component includes a tubular structure with openings at both ends.

[0014] Optionally, the bottom of the frame is provided with a connecting structure for connecting the lower reinforcing bars of the precast box girder.

[0015] As can be seen from the above, the matching diaphragm support system provided in this application uses a frame as the structural foundation of the diaphragm. The frame supports and positions the anchorage components, ensuring that the location of the anchorage components corresponds to the position of the anchorage on the diaphragm. This improves the positioning accuracy of the anchorage on the diaphragm, limiting the positioning error to below 3mm. When on-site construction workers are tying reinforcing bars, the anchorage components connected to the frame ensure the designed length of the reinforcing bars after anchoring. Construction workers only need to ensure that the reinforcing bars avoid the anchorage components to ensure smooth installation of the anchorage, which helps reduce the difficulty of preparing the reinforcing bar skeleton of the diaphragm.

[0016] In addition, since the center of gravity of the anchor type is close to its center point, that is, the weight of the anchor type is more even, it is easier to ensure that the anchor type can be stably held on the frame, which can not only ensure construction safety and reduce technical risks on the construction site, but also help improve construction efficiency.

[0036] like Figure 1 The transverse diaphragm 200 is installed in the middle hole 110 of the precast box girder 100, and the transverse diaphragm 200 is equipped with anchors 500, both ends of which are exposed.

[0037] like Figure 5 In some embodiments, multiple reinforcing bars are welded and / or tied together to form an inner reinforcing bar skeleton 210 for constructing a transverse diaphragm 200 and an outer reinforcing bar skeleton 120 for constructing a precast box girder 100.

[0038] Before pouring the inner steel reinforcement cage 210, the anchor 500 needs to be positioned in the designed position in the inner steel reinforcement cage 210 to ensure that after the transverse diaphragm 200 is formed, the anchor 500 can be stably fixed in the transverse diaphragm 200, and the position of the anchor 500 meets the design requirements.

[0039] Combination Figure 1 and Figure 2 As can be seen, the middle part of the anchor 500 is a tubular structure, but the structures at both ends are different. One end has a square structure on the outside of the tubular structure, while the other end has a porous structure inside the tubular structure. It is precisely because of the different structures at both ends of the anchor 500 that the position of the center of gravity of the anchor 500 deviates significantly from the position of the structural center, that is, the weight of the anchor 500 is severely eccentric.

[0040] If the anchor 500 is directly connected to the steel bars of the inner steel reinforcement cage 210 during the preparation of the inner steel reinforcement cage 210, the anchor 500 may not be securely fixed due to the severe weight eccentricity of the anchor 500. This will cause inconvenience to the subsequent preparation process of the inner steel reinforcement cage 210 and increase the risk of safety accidents.

[0041] To solve the above problems, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 This application provides a support system for a matching crossbeam, including: a frame 300, including a first end face 310 and a second end face 320 disposed opposite to each other, and a positioning through hole 330 formed in the frame 300 through the first end face 310 and the second end face 320; and an anchor type 400, detachably connected to the positioning through hole 330, with the center of gravity of the anchor type 400 close to the center point of the anchor type 400.

[0042] For example, the frame 300 can be a frame formed by welding or bolting together multiple column structures.

[0043] For example, when the frame 300 includes a frame formed by multiple columnar structures, positioning through holes 330 can be defined between adjacent columnar structures.

[0044] For example, the external dimensions of the anchor type 400 connected in the positioning through hole 330 are the same as the external dimensions of the anchor 500 located in the diaphragm 200.

[0045] For example, the anchor type 400 can be detachably connected to the frame 300 by plugging or snapping.

[0046] For example, the frame 300 can be connected to the outer steel reinforcement frame 120 (e.g., by welding or bolting).

[0047] For example, the anchor type 400 can be a lightweight solid structural component or a hollow structural component.

[0048] For example, the anchor type 400 can be installed into the positioning through hole 330 of the frame 300 after the frame 300 is prepared.

[0049] In this embodiment, the frame 300 can be manufactured according to the design dimensions, and a positioning through hole 330 is formed at the position where the anchor 500 is installed, according to the design.

[0050] like Figure 3 and Figure 4 The frame 300 can be connected to the middle hole 110 of the outer steel reinforcement frame 120. The first end face 310 of the frame 300 faces one end of the outer steel reinforcement frame 120, and the second end face 320 faces the other end of the outer steel reinforcement frame 120.

[0051] like Figure 5 During the process of forming the inner steel reinforcement skeleton 210 based on the frame 300, the anchor 400 remains detachably connected to the frame 300. As long as interference between the inner steel reinforcement skeleton 210 and the anchor 400 is avoided, the anchor 500 can be smoothly installed into the positioning through hole 330 after the anchor 400 is removed from the frame 300.

[0052] When pouring is required, such as Figure 6 First, all anchor components 400 are removed from the frame 300. Then, the anchor 500 is installed into the positioning through hole 330 and positioned with the frame 300. After that, the support system and inner steel reinforcement skeleton 210 of this embodiment are poured to form the transverse diaphragm beam 200.

[0053] The matching crossbeam support system provided in this embodiment uses a frame 300 as the structural foundation of the crossbeam 200. The frame 300 supports and positions the anchor components 400, ensuring that the position of the anchor components 400 corresponds to the position of the anchor 500 on the crossbeam 200. This improves the positioning accuracy of the anchor 500 on the crossbeam 200, limiting the positioning error to below 3mm. When on-site construction workers are tying reinforcing bars, the anchor components 400 connected to the frame 300 ensure the designed length of the reinforcing bars after anchoring. Construction workers only need to ensure that the reinforcing bars avoid the anchor components 400 to ensure smooth installation of the anchor 500, which helps reduce the difficulty of preparing the reinforcing bar skeleton of the crossbeam 200.

[0054] In addition, since the center of gravity of the anchor type 400 is close to its center point, that is, the weight of the anchor type 400 is more even, it is easier to ensure that the anchor type 400 can be stably held on the frame 300, which can not only ensure construction safety and reduce technical risks on the construction site, but also help improve construction efficiency.

[0055] like Figure 3 and Figure 4 In some embodiments, the frame 300 includes a plurality of vertical steel sections 350 and a plurality of horizontal steel sections 340. The plurality of vertical steel sections 350 are spaced apart, and two adjacent vertical steel sections 350 are connected by horizontal steel sections 340. The vertical steel sections 350 and horizontal steel sections 340 define positioning through holes 330.

[0056] For example, multiple vertical steel sections 350 can be divided into two groups, one group of which consists of vertical steel sections 350 along a first direction (e.g., Figure 3 The two sets of vertical steel sections 350 are arranged side-by-side with spacing along the X direction, and another set is also arranged side-by-side with spacing along the first direction, and the two sets of vertical steel sections 350 are arranged along the second direction (e.g., along the X direction). Figure 4 The two sets of vertical steel sections 350 are spaced apart in the Y direction, with the first and second directions being horizontal and perpendicular to each other. The opposing surfaces of the two sets of vertical steel sections 350 form a first end face 310 and a second end face 320. Adjacent vertical steel sections 350 in the same set (i.e., adjacent along the first direction) can be connected by a transverse steel section 340, and adjacent vertical steel sections 350 belonging to two different sets (i.e., adjacent along the second direction) can also be connected by a transverse steel section 340.

[0057] For example, the vertical steel section 350 and the horizontal steel section 340 can be connected by welding, snap-fitting or fastener connection.

[0058] Based on the advantages of high uniformity of steel profile dimensions and ease of cutting and processing, the frame 300 is constructed by connecting the horizontal steel profiles 340 and the vertical steel profiles 350. On the one hand, this can reduce the difficulty of manufacturing the frame 300 and shorten the manufacturing period, and on the other hand, it can also help reduce the manufacturing cost of the frame 300.

[0059] Meanwhile, as can be seen from the foregoing, the frame 300 is used to position and support the anchor type 400. The frame 300, which is constructed by the horizontal steel 340 and the vertical steel 350, has a frame structure. While ensuring reliable support for the anchor type 400, it also keeps the frame 300 itself relatively light, making it easy to construct.

[0060] like Figure 3 and Figure 4 In some embodiments, the transverse steel 340 includes supporting steel 341 located on the first end face 310 and the second end face 320 respectively, and the two ends of the anchor member 400 extend out of the first end face 310 and the second end face 320 respectively, with the supporting steel 341 supporting the anchor member 400.

[0061] For example, the supporting steel 341 on the first end face 310 and the supporting steel 341 on the second end face 320 correspond one-to-one.

[0062] For example, the anchor type 400 is detachably connected to the support type 341.

[0063] Corresponding to the arrangement of the anchor 500 on the crossbeam 200, both ends of the anchor member 400 need to extend out of the frame 300. Since the thickness of the crossbeam 200 (the dimension along the direction from the first end face 310 to the second end face 320 of the frame 300) is small, the corresponding dimension of the frame 300 in this direction, as well as the axial dimension of the anchor member 400, are also small. As long as the anchor member 400 is supported near its end, it can be ensured that the anchor member 400 can be stably connected to the frame 300.

[0064] In this embodiment, the supporting steel 341 on the first end face 310 and the supporting steel 341 on the second end face 320 respectively support the positions near both ends of the same anchor member 400. Under the combined action of the two, the anchor member 400 can be stably held in the positioning through hole 330 of the frame 300.

[0065] like Figure 4In some embodiments, the transverse steel 340 further includes a connecting steel 342 located between the first end face 310 and the second end face 320, the size of the connecting steel 342 being smaller than the size of the supporting steel 341.

[0066] For example, multiple vertical steel sections 350 can be divided into two groups, and the two groups of vertical steel sections 350 are connected by connecting steel sections 342.

[0067] Connecting steel section 342 is used to provide tension to at least two vertical steel sections 350, so that the vertical steel sections 350 can form a stable frame structure under the action of connecting steel section 342. Therefore, the structural strength requirement of connecting steel section 342 is relatively low. Designing connecting steel section 342 as a small structure can help reduce the manufacturing cost and weight of frame 300 while ensuring that its structural strength meets the requirements.

[0068] As described above, the supporting steel 341 not only provides tension to the vertical steel 350 but also supports the anchor component 400. If the supporting steel 341 bends due to insufficient structural strength, it will not only affect the positioning accuracy of the anchor component 400 but may even cause the anchor component 400 to separate from the frame 300, posing a safety risk. Therefore, in this embodiment, the supporting steel 341 is designed with a large structure to ensure greater structural strength and that the anchor component 400 it supports remains in the designed position.

[0069] like Figure 3 and Figure 4 In some embodiments, both the vertical steel section 350 and the horizontal steel section 340 are channel steel.

[0070] Channel steel has good mechanical properties, especially strong resistance to bending and torsion. It can not only ensure the structural stability of the frame 300, but also provide reliable support for the anchor 400, which helps to improve the positioning accuracy of the anchor 400.

[0071] Meanwhile, channel steel is lightweight, easy to process and shape to adjust, and can be quickly cut and connected according to size requirements, which can efficiently produce a frame 300 that conforms to the structure of the crossbeam 200.

[0072] like Figure 3 In some embodiments, the vertical steel section 350 is welded to the horizontal steel section 340 or connected by fasteners.

[0073] For example, the fastener can be a bolt and a nut that mates with the bolt, or it can be a threaded post and a nut that mates with the threaded post.

[0074] When the vertical steel section 350 and the horizontal steel section 340 are channel steel, the weld marks formed by welding are sufficient to form a reliable connection between the vertical steel section 350 and the horizontal steel section 340 because the channel steel is relatively light and has a relatively flat outer surface.

[0075] Of course, channel steel also has the characteristic of being relatively thin, making it easy for fasteners such as bolts to pass through. Therefore, such as Figure 7 Alternatively, bolts can be inserted through the vertical steel section 350 and the horizontal steel section 340 to be connected, and the vertical steel section 350 and the horizontal steel section 340 can be locked and fixed by nuts that match the bolts.

[0076] like Figure 3 , Figure 4 and Figure 7 In some embodiments, the slot of the support steel 341 is set horizontally.

[0077] by Figure 7 Taking the structure shown as an example, the dimension L1 of the channel steel along the depth direction of the channel opening is smaller, while the dimension L2 along the width direction of the channel opening is larger. When the channel steel is horizontally positioned, its vertical dimension is larger, which can support a greater weight.

[0078] Therefore, when the slot of the support steel 341 is set horizontally, it can further prevent the support steel 341 from bending and deforming under the gravity of the anchor part 400, which helps to improve the positioning accuracy of the anchor part 400.

[0079] like Figure 3 and Figure 4 In some embodiments, the anchor member 400 has an inner cavity 410 formed inside.

[0080] As can be seen from the foregoing, in the embodiments of this application, the anchor type 400 simulates the external dimensions of the anchor 500. Therefore, the internal structure of the anchor type 400 does not affect its function in the support system. To minimize the weight of the anchor type 400, this embodiment forms an inner cavity 410 inside the anchor type 400. Without affecting the external dimensions of the anchor type 400 simulating the anchor 500, this further reduces the reliability of the connection between the anchor type 400 and the frame 300, which helps to further reduce construction difficulty and improve construction safety.

[0081] like Figure 3 and Figure 4 In some embodiments, the anchor type 400 includes a tubular structure with openings at both ends.

[0082] Designing the anchor component 400 as a tubular structure with open ends not only makes it easier to ensure that the center of gravity of the anchor component 400 coincides with the center of the structure, but also facilitates the transportation and installation of the anchor component 400, which helps to further reduce the difficulty of construction.

[0083] like Figure 3 In some embodiments, the bottom of the frame 300 is formed with a connection structure for connecting the lower reinforcing bars 121 of the precast box girder 100.

[0084] For example, the ends of the vertical steel section 350 can be configured as a connecting structure.

[0085] For example, the connection structure can be connected to the lower reinforcing bars 121 of the precast box girder 100 by fasteners or welding.

[0086] For example, the transverse steel 340 in the frame 300 can be connected to the outer steel reinforcement skeleton 120 of the precast box girder 100.

[0087] The connecting structure allows the frame 300 to be stably and reliably connected to the outer steel reinforcement skeleton 120 of the precast box girder 100, ensuring that the frame 300 can be kept in the designed position within the outer steel reinforcement skeleton 120 of the precast box girder 100. It also helps to improve the positioning accuracy of the anchorage 400 connected to the frame 300, ensuring that the position of the anchorage 500 fixed inside the transverse diaphragm 200 after the transverse diaphragm 200 is formed has a small error compared with the designed position.
