Description

Technical Field

[0001] The utility model relates to the technical field of building corridor construction, in particular to a connection component used for early unloading of a steel corridor on a steel concrete corbel. Background Art

[0002] In modern architecture, large-span steel corridors are widely used in commercial complexes, large public facilities and other projects as a structure connecting different buildings. Steel corridors usually use steel structures as the main support system. In order to enhance the connection strength and seismic performance between them and the main building, steel concrete corbels are often installed at the connection points, which can not only effectively transfer loads but also increase the overall stability of the structure.

[0003] In traditional construction methods, steel concrete corbels are important load-bearing and connecting components. Their construction process usually includes prefabricating molds, pouring concrete, and waiting for the concrete to air-dry and solidify before the steel corridor can be erected. This process is not only complicated and time-consuming, but also involves multiple step-by-step operations, such as the erection and dismantling of formwork, concrete curing, etc. Each step requires strict quality control and time planning, which can easily increase construction costs and extend construction period in actual construction, and there are safety hazards during high-altitude welding and positioning.

[0004] Therefore, a construction method for early unloading of a large-span steel corridor on a steel-concrete corbel can be designed, which can be suitable for directly performing steel-concrete corbel welding operations when the steel corridor corbel is lifted, so as to facilitate early unloading of the large-span steel corridor.

[0005] In this construction method, in order to make the structure better adapt to the slight deformation during the construction process, corresponding connection components are generally set on the steel concrete corbels to improve the toughness, load-bearing capacity and rigidity of the overall structure when the corridor is erected, ensuring the accuracy of the corbel installation and the stability of the structure.

[0006] To this end, the present application specifically proposes a connection assembly for early unloading of a steel corridor on a steel concrete corbel to solve the above-mentioned technical problems. Utility Model Content

[0007] The main purpose of the utility model is to provide a connection assembly for unloading the steel corridor on the steel concrete corbel in advance, which can ensure that the corbel is evenly stressed when supporting the steel corridor, so that the load can be smoothly transferred from the cantilever beam under the steel corridor to the supporting structure, and at the same time can effectively resist the shear force and torque in the horizontal direction to solve the above-mentioned technical problems.

[0008] In order to solve the above technical problems, the utility model provides a connection assembly for unloading the steel corridor in advance on the steel concrete corbel, which is arranged as a force-bearing connection structure located on the steel corbel, the steel corbel is installed on the reserved corbel, and the top of the force-bearing connection structure supports the steel corridor lower suspension beam, and the force-bearing connection structure includes:

[0009] The elastic bracket is set at the bottom of the cantilever beam under the steel corridor through high-strength bolts or chemical anchors;

[0010] The upper buried plate is set at the bottom of the elastic support by bolts or chemical anchors;

[0011] The buried plate is welded or connected to the steel bracket with high-strength bolts;

[0012] The I-beam embedded parts are arranged with the I-beam upward and evenly distributed above the lower embedded plate body, and the tops of the I-beam embedded parts are in contact with the upper embedded plate.

[0013] Furthermore, the force-bearing connection structure also includes a plurality of short steel bars arranged at the bottom of the upper embedded plate, the length of the short steel bars is less than the height of the I-beam embedded part, and U-shaped grooves are formed on both sides of the I-beam embedded part, and the short steel bars are all fitted on the inner wall of the U-shaped groove.

[0014] Furthermore, the force-bearing connection structure also includes at least three groups of embedded plate connectors, which are used to connect and control the upper embedded plate and the lower embedded plate to move closer to or farther away from each other, and the embedded plate connectors are all located at the corners of the upper embedded plate and the lower embedded plate.

[0015] Furthermore, the embedded plate connecting piece includes a screw structure and an upper nut with threads arranged on the top of the screw structure. The middle part of the screw structure passes through the upper embedded plate and is threadedly connected to the lower embedded plate.

[0016] Furthermore, the embedded plate connecting member includes a screw structure, an upper nut and a lower nut passing through the upper embedded plate and the lower embedded plate, the upper nut is located above the upper embedded plate and threadedly connected to the screw structure, and the lower nut is located below the lower embedded plate and threadedly connected to the screw structure.

[0017] Furthermore, the screw structure is configured as a bidirectional screw.

[0018] The beneficial effects of the utility model are embodied in:

[0019] 1. The load-bearing connection structure of the utility model can ensure that the corbel is evenly stressed when supporting the steel corridor by arranging a plurality of evenly distributed I-beam embedded parts, so that the load can be smoothly transferred from the suspended beam under the steel corridor to the supporting structure, and then distributed to the foundation, ensuring even load distribution and avoiding the generation of concentrated stress, thereby improving the load-bearing effect of the corbel on the building.

[0020] 2. The utility model can connect and control the upper buried plate and the lower buried plate to move closer or farther away from each other by setting the buried plate connecting parts. At this time, the short-direction steel bars can limit the I-beam embedded parts, ensuring the accurate fixation of the I-beam embedded parts in the preset positions, preventing displacement due to external forces during the construction process, and improving the accuracy and reliability of the installation.

[0021] 3.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] In the embodiment, see Figures 1 to 4 .

[0032] like Figure 1 The utility model shown provides a connection component for early unloading of a steel corridor on a steel concrete corbel, which is arranged as a force-bearing connection structure 4 located on the steel corbel 3, and is used for unloading support of the steel corridor lower suspension beam 2 on the steel corbel 3. The steel corbel 3 is installed on the reserved corbel 1, and the top of the force-bearing connection structure 4 is supported by the steel corridor lower suspension beam 2. Therefore, the force-bearing connection structure 4 can ensure that the corbel is evenly stressed when supporting the steel corridor, so that the load can be smoothly transferred from the steel corridor lower suspension beam 2 to the supporting structure, thereby improving the force-bearing effect of the corbel on the building.

[0033] Specifically, Figure 2 As shown, the force-bearing connection structure 4 includes:

[0034] The elastic bracket 41 is arranged at the bottom of the cantilever beam 2 under the steel corridor by means of high-strength bolts or chemical anchor bolts;

[0035] The upper embedded plate 42 is arranged at the bottom of the elastic support 41 by bolts or chemical anchors;

[0036] The buried plate 43 is welded or connected to the steel bracket 3 using high-strength bolts;

[0037] The I-beam embedded parts 45 are evenly distributed above the lower embedded plate 43 , and the tops of the I-beam embedded parts 45 are in contact with the upper embedded plate 42 .

[0038] In a specific implementation, the load-bearing connection structure 4 can ensure uniform load on the corbel when supporting the steel corridor by setting a plurality of evenly distributed I-beam embedded parts 45, so that the load can be smoothly transferred from the cantilever beam 2 under the steel corridor to the supporting structure, and then distributed to the foundation, ensuring uniform load distribution and avoiding the generation of concentrated stress, thereby improving the load-bearing effect of the corbel on the building.

[0039] The elastic bracket 41 is generally an elastic rubber bracket in the prior art, and should be close to the reserved corbel 1 during the installation of the force-bearing connection structure 4 to improve the overall bearing effect of the corbel.

[0040] Before the I-beam embedded part 45 is installed and laid out, the need for future structural connection must be considered. During installation, it must be ensured that there is enough space around the I-beam embedded part 45 to facilitate subsequent welding or bolting. At the same time, it is also necessary to consider the possible gaps between components to accommodate expansion or contraction caused by different temperature changes.

[0041] It should be noted that the I-beam embedded parts 45 should be in an I-shaped upward posture during the placement process, and the connection postures of the I-beam embedded parts 45 are consistent, so as to meet the dynamic load requirements of the overall structure.

[0042] In addition, the I-beam embedded part 45 should be sandblasted for rust removal or coated with primer for rust prevention before placement, so as to prevent the I-beam embedded part 45 from rusting after concrete pouring, thereby improving the durability and strength of the structure.

[0043] Further, such as Figure 3 As shown, the force-bearing connection structure 4 also includes a plurality of short steel bars 44 arranged at the bottom of the upper embedded plate 42. The length of the short steel bars 44 is less than the height of the I-beam embedded part 45, and U-shaped grooves 451 are formed on both sides of the I-beam embedded part 45. The short steel bars 44 are all arranged on the inner wall of the U-shaped groove 451.

[0044] In a specific implementation, by arranging a plurality of groups of short-direction steel bars 44 on the inner side of the U-shaped groove 451 of the I-beam embedded part 45, it is possible to limit the I-beam embedded part 45 and improve the overall structure's ability to withstand vertical loads from the upper structure, while effectively resisting horizontal shear forces and torques. Especially under extreme conditions such as strong winds and earthquakes, it is possible to significantly improve the overall stiffness and stability of the structure and reduce the risk of damage caused by deformation.

[0045] It should be noted that the above-mentioned short-direction steel bars 44 are structural components commonly used in the engineering field, so their specific structure and installation method are not described in detail here.

[0046] The force-bearing connection structure 4 also includes at least three groups of embedded plate connectors 46, which are used to connect and control the upper embedded plate 42 and the lower embedded plate 43 to move closer to or farther away from each other, and the embedded plate connectors 46 are all located at the corners of the upper embedded plate 42 and the lower embedded plate 43, which are used to facilitate the rapid removal of the embedded plate connectors 46 after the force-bearing connection structure 4 is placed.

[0047] In a specific implementation, by setting the embedded plate connecting member 46, the upper embedded plate 42 and the lower embedded plate 43 can be connected and controlled to be close to or away from each other. At this time, the short-direction steel bars 44 can limit the I-beam embedded member 45, ensuring that the I-beam embedded member 45 is accurately fixed in a preset position, preventing displacement due to external force during construction, and improving the accuracy and reliability of installation.

[0048] In further embodiments, the structure of the buried plate connector 46 can be referred to Figure 4.

[0049] In a specific embodiment, the buried plate connector 46 includes a screw structure and an upper nut 462 threadedly disposed on the top of the screw structure. The middle portion of the screw structure passes through the upper buried plate 42 and is threadedly connected to the lower buried plate 43.

[0050] In a specific implementation, by rotating the screw structure, the bottom buried plate 43 can be controlled to move up and down. At this time, the upper buried plate 42 can move freely up and down. When the top of the I-beam embedded part 45 contacts the upper buried plate 42, the upper buried plate 42 and the lower buried plate 43 are close to each other to the minimum distance. At this time, the upper nut 462 can be rotated to cooperate with the compression and positioning of the upper buried plate 42, the lower buried plate 43, the short-direction steel bars 44, and the I-beam embedded part 45. At the same time, during the disassembly process, the upper nut 462 and the screw structure can be removed in turn to complete the overall structural disassembly operation of the buried plate connector 46.

[0051] It can be further explained that the screw structure here can also be set as a bidirectional screw 461.

[0052] At this time, during the implementation process, the bidirectional screw 461 can also be threadedly connected to the upper buried plate 42. When the bidirectional screw 461 rotates, the upper buried plate 42 and the lower buried plate 43 can be controlled to move closer or farther away from each other. The upper nut 462 here is threadedly rotated on the bidirectional screw 461, and only serves to cooperate and fix the position of the upper buried plate 42 and the lower buried plate 43.

[0053] In a specific embodiment, the buried plate connector 46 includes a screw structure passing through the upper buried plate 42 and the lower buried plate 43, an upper nut 462 and a lower nut 463, the upper nut 462 is located above the upper buried plate 42 and is threadedly connected to the screw structure, and the lower nut 463 is located below the lower buried plate 43 and is threadedly connected to the screw structure.

[0054] In the specific implementation, the screw structure passes through the upper embedded plate 42 and the lower embedded plate 43. At this time, the upper embedded plate 42 and the lower embedded plate 43 can be pushed and controlled to approach each other by rotating the upper nut 462 and the lower nut 463. When the top of the I-beam embedded part 45 contacts the upper embedded plate 42, the upper embedded plate 42 and the lower embedded plate 43 are close to each other to the minimum distance. At this time, the upper nut 462 and the lower nut 463 cooperate with each other to press and position the upper embedded plate 42, the lower embedded plate 43, the short-direction steel bars 44, and the I-beam embedded part 45. At the same time, during the disassembly process, the upper nut 462, the lower nut 463 and the screw structure are removed in sequence to complete the overall structural disassembly operation of the embedded plate connector 46.

[0055] It can be further explained that the screw structure here can also be set as a bidirectional screw 461

[0056] At this time, during the implementation process, the bidirectional screw 461 is threadedly connected to the upper buried plate 42 and the lower buried plate 43. When the bidirectional screw 461 is rotated, the upper buried plate 42 and the lower buried plate 43 can be controlled to move closer to or farther away from each other. The upper nut 462 and the lower nut 463 here are threadedly rotated on the bidirectional screw 461, and only serve to cooperate and fix the position of the upper buried plate 42 and the lower buried plate 43.

[0057] In summary, the embedded plate connector 46, through the combination of the screw structure and the nut, can effectively and accurately control the upper embedded plate 42 and the lower embedded plate 43 to move closer or farther away from each other, thereby controlling the mutual coordination and connection between the components, and can also quickly and conveniently disassemble the embedded plate connector 46 on the upper and lower sets of embedded plates after the component connection is completed and the steel corridor is unloaded, which is convenient for use.

If the specific posture changes, the directional indications will also change accordingly.
