[0022] It should be noted that the modification of "one" or "multiple" mentioned in the present application is illustrative and not limiting, and those skilled in the art should understand that unless otherwise explicitly indicated in the context, it should be understood as "one or more".

[0023] In the related art, during the use of engineering, for example, the construction of temporary structures such as safety shelters, work platforms, etc., it is common to connect the upper and lower overlaps of I-beams, and the current connection between the main beam and the secondary beam of the I-beam usually adopts a welding method. However, the welding method may have many drawbacks, for example, when a large amount of connection work is required, since welding work is a special operation, a large number of professional workers are required to operate, and the welding process also consumes a lot of time and effort. In the subsequent use stage, the weld is often subjected to complex external forces, and the risk of cracking is high, which seriously affects the construction efficiency and safety of the I-beam construction, and in the disassembly process, a large number of professional workers are also required to consume a long time for disassembly.

[0024] In view of the problems existing in the above related technology, the present application provides an I-beam connecting device.

[0025] As Figure 1 and 2As shown, the utility model embodiment provides a kind of I-shaped steel connecting device, including support 1 and clamp 2, the support 1 includes bearing plate 11, first connecting plate 12 and second connecting plate 14, the bottom surface of bearing plate 11 is sequentially provided with first connecting plate 12 and second connecting plate 14 along first direction, first connecting plate 12 and second connecting plate 14 are respectively perpendicular to bearing plate 11, for the main beam I-shaped steel 3 for being arranged between first connecting plate 12 and second connecting plate 14, first connecting plate 12 and second connecting plate 14 are respectively used to connect with the transverse stiffening rib of the both sides of main beam I-shaped steel 3, clamp 2 includes first connecting assembly 21 and second connecting assembly 22, first connecting assembly 21 and second connecting assembly 22 are sequentially arranged on the top surface of bearing plate 11 along second direction respectively, for the secondary beam I-shaped steel 4 for being arranged between first connecting assembly 21 and second connecting assembly 22, first connecting assembly 21 and second connecting assembly 22 are respectively used to connect with the web of both sides of secondary beam I-shaped steel 4, first direction, second direction and vertical direction are pairwise perpendicular.

[0026] It needs to be explained that when two I-shaped steels are connected, the I-shaped steel located below is used as main beam I-shaped steel 3, and the I-shaped steel stacked above main beam I-shaped steel 3 is used as secondary beam I-shaped steel 4, wherein the axial direction of secondary beam I-shaped steel 4 is first direction, and the axial direction of main beam I-shaped steel 3 is second direction, since I-shaped steel is usually cross, first direction and second direction are perpendicular, and first direction, second direction and vertical direction are pairwise perpendicular.

[0027] Specifically, the I-beam connecting device includes a bracket 1 and a clamp 2, the bracket 1 includes a bearing plate 11, a first connecting plate 12 and a second connecting plate 14, the bearing plate 11 serves as a base component of the entire device and plays a role of bearing and connecting other components, the bearing plate 11 is a flat plate surface, providing a stable support plane for the installation of subsequent components. The first connecting plate 12 and the second connecting plate 14 are sequentially arranged on the bottom surface of the bearing plate 11 in a vertical posture with respect to the bearing plate 11 along a first direction, and the first connecting plate 12 and the second connecting plate 14 can be located in the same plane, thereby facilitating the two to be respectively attached to and connected with the transverse stiffening ribs symmetrically arranged on both sides of the main beam I-beam 3. The space formed between the first connecting plate 12 and the second connecting plate 14 can facilitate the main beam I-beam 3 to be arranged, so that the main beam I-beam 3 can be quickly and accurately positioned, ensuring the accuracy and stability of the installation position of the main beam I-beam 3. Moreover, the first connecting plate 12 and the second connecting plate 14 are respectively connected with the transverse stiffening ribs on both sides of the main beam I-beam 3, for example, by a locking member, wherein the transverse stiffening ribs are structures for enhancing the lateral stiffness of the main beam I-beam 3, and the connection thereof makes the entire structural system more stable when subjected to lateral force, and the force is more evenly dispersed, thereby improving the overall load-carrying capacity. The clamp 2 includes a first connecting assembly 21 and a second connecting assembly 22, the first connecting assembly 21 and the second connecting assembly 22 are sequentially arranged on the top surface of the bearing plate 11 along a second direction, and a space for arranging the secondary beam I-beam 4 is reserved between the first connecting assembly 21 and the second connecting assembly 22, so that the secondary beam I-beam 4 can be arranged in the predetermined position and fixed. Moreover, the first connecting assembly 21 and the second connecting assembly 22 are respectively connected with both sides of the web of the secondary beam I-beam 4, for example, by a locking member, the web of the secondary beam I-beam 4 is an important part for bearing vertical shear force, and the clamp 2 is connected with both sides of the web through the first connecting assembly 21 and the second connecting assembly 22, so as to firmly fix the secondary beam I-beam 4, thereby ensuring that the secondary beam I-beam 4 forms a stable connection relationship with the bracket 1 and the main beam I-beam 3. Since the first direction, the second direction and the vertical direction are perpendicular to each other, i.e., the main beam I-beam 3 and the secondary beam I-beam 4 are perpendicular after being connected, the force can be transmitted along the most reasonable and direct path, avoiding the concentration or unreasonable twisting of the force, which is helpful to build a stable and efficient force-receiving structure, and can ensure the safety of the structure by relying on the reasonable architecture, no matter whether it is subjected to vertical gravity load or horizontal wind load, earthquake force and other lateral forces.

[0028] In this embodiment, the carrier 1 is connected with the transverse stiffening ribs on both sides of the main beam I-steel 3 through the first connecting plate 12 and the second connecting plate 14, which can effectively enhance the lateral stiffness of the main beam I-steel 3, making the whole structure more stable when subjected to lateral force. At the same time, the space between the first connecting plate 12 and the second connecting plate 14 of the carrier 1 is formed, and the main beam I-steel 3 can be directly arranged therein, so that the main beam I-steel 3 is accurately positioned by the first connecting plate 12 and the second connecting plate 14, reducing the time for repeatedly adjusting the position of the main beam I-steel 3 on site, and the construction personnel do not need to spend a lot of effort to calibrate the installation position, so that the preliminary assembly of the main beam part can be quickly completed, and the construction efficiency is improved. The clamp 2 is connected with the web plate on both sides of the secondary beam I-steel 4 through the first connecting assembly 21 and the second connecting assembly 22, and the secondary beam I-steel 4 is firmly fixed, so that the main beam I-steel 3 and the secondary beam I-steel 4 form a stable connection relationship, and the rigidity of the structure is improved in all directions, which is enough to cope with complex external force and reduce the risk of structural deformation. The space for accommodating the secondary beam I-steel 4 is reserved between the first connecting assembly 21 and the second connecting assembly 22 of the clamp 2, so that the secondary beam I-steel 4 can be quickly positioned at the predetermined position without complex measurement and adjustment, so that the main beam I-steel 3 and the secondary beam I-steel 4 are quickly and accurately connected through the I-steel connecting device. Compared with directly welding the main beam I-steel 3 and the secondary beam I-steel 4, the construction steps can be simplified, the overall installation efficiency is improved, and since the first direction, the second direction and the vertical direction are perpendicular to each other, the main beam I-steel 3 and the secondary beam I-steel 4 are perpendicular to each other after connection, so that the force can be transmitted along the most reasonable path, avoiding the concentration and unreasonable twisting of the force, maintaining the stability of the structure, reducing the probability of damage to the key parts due to uneven stress, and ensuring long-term safe use.

[0029] Optionally, as shown in Figure 1 and 2 , the transverse stiffening ribs on both sides of the main beam I-steel 3 include symmetrically arranged first transverse stiffening ribs 5 and second transverse stiffening ribs 6, and the first connecting plate 12 extends a first side ear 13 on one side close to the second connecting plate 14, and the first side ear 13 is connected with the first transverse stiffening rib 5.

[0030] Optionally, the first side ear 13 and the first transverse stiffening rib 5 are connected by bolts.

[0031] Optionally, the second connecting plate 14 extends a second side ear 15 on one side close to the first connecting plate 12, and the second side ear 15 is connected with the second transverse stiffening rib 6.

[0032] Optionally, the second side ear 15 and the second transverse stiffening rib 6 are connected by bolts.

[0033] In the optional embodiment, the first transverse stiffening rib 5 and the second transverse stiffening rib 6 are arranged on the two sides of the main girder I-beam 3 respectively, the first connecting plate 12 extends the first side lug 13 towards the second connecting plate 14, and the first side lug 13 is connected with the first transverse stiffening rib 5 through bolts. The bolt connection does not require professional welders, and ordinary construction personnel can quickly complete the installation using simple tools, greatly speeding up the construction and improving the construction efficiency. In the subsequent demolition stage, the bolt can be used for rapid disassembly, and the damage to the surrounding structure of the I-beam caused by the welding part during disassembly can be avoided. In addition, the bolt connection is less affected by environmental factors. Even in a relatively harsh outdoor construction environment, the work can be carried out stably after slight protection, ensuring that the construction period is not affected. Similarly, the second side lug 15 extending from the side of the second connecting plate 14 close to the first connecting plate 12 is connected with the second transverse stiffening rib 6 through a symmetrical connection relationship, so that the force is evenly distributed on the two sides of the main girder I-beam 3, maintaining the balance of the overall force of the structure. The second side lug 15 is connected with the second transverse stiffening rib 6 through bolts, which is the same as the connection of the first side lug 13. The bolt connection unifies and standardizes the connection mode on both sides, which is easier for construction personnel to master the operation process, and from the quality control point of view, as long as the specifications of the bolts are correct and the tightening torque meets the standard, the connection effect can be stably realized, the structural hidden danger caused by improper connection is minimized, the safety and reliability of the entire structure system are improved, the main girder I-beam 3 and the bolster 1 are closely connected, and various vertical and horizontal loads are cooperatively coped with.

Meanwhile, in order to enhance the stability of the connection, a plurality of groups of through holes can be arranged at appropriate positions of the first bottom plate 211 and the bearing plate 11 and are respectively connected through bolts. When the I-beam is connected by the construction personnel, the bolt connection only needs simple tools and can quickly complete the installation and disassembly. In the construction site, in the face of different working conditions or subsequent processing processes, only the nut is unscrewed and the bolt is pulled out, the first connecting assembly 21 can be quickly disassembled, the bearing plate 11 and the first connecting assembly 21 are not damaged, the related parts can be flexibly adjusted and replaced, and the bolt connection has strong adaptability to the construction environment. Compared with the welding connection mode, in the complex environment such as high humidity and outdoor environment, the bolt connection can still stably achieve high-quality connection and ensure that the construction progress is not excessively disturbed by environmental factors. The first connecting arm 212 is vertically connected to the top surface of the first bottom plate 211, the first connecting arm 212 plays a role of extension and transition, so that the subsequent connecting structure can span a certain distance and be accurately positioned to the corresponding position of the web of the I-beam 4. Since the first side arm and the first pad plate do not need to be frequently disassembled, the welding can be used for fixed connection. The other end of the first connecting arm 212 extends the third connecting arm 213 in the direction close to the second connecting assembly 22, the first connecting arm 212 and the third connecting arm 213 form an L shape, the extension end of the third connecting arm 213 is connected with one side of the first clamping plate 214, and the welding mode can also be used for the pre-fixed connection. The extended side arm can make the other side of the first clamping plate 214 tightly connected with the web of the I-beam 4, so that the I-beam 4 is fixed and supported through the connecting arm clamping plate.

The width of the rectangular through hole matches the diameter of the third through hole. During construction, the second bolt is respectively threaded through the rectangular through hole and the third through hole and is screwed with the second nut, thereby fixing the second bottom plate 221 on the bearing plate 11. The operation is simple and convenient, and ordinary construction personnel can quickly complete it using a wrench and other tools, thereby accelerating the construction speed. Moreover, the redundant space left by the rectangular through hole along the second direction gives the second connecting assembly 22 a certain degree of flexibility in fine adjustment along the second direction. For example, during on-site assembly, if there is a slight deviation in the size or installation position of the secondary beam I-beam 4, this adjustable space can be used to slightly move the second connecting assembly 22 without the need to re-drill holes or modify components, thereby accurately adapting to the situation and greatly improving the fault tolerance of on-site installation, reducing construction difficulty, ensuring smooth construction, and providing convenience for subsequent maintenance work such as component replacement. In order to further improve the stability of the connection between the second bottom plate 221 and the bearing plate 11, a plurality of rectangular through holes can be formed in the bearing plate 11, and a plurality of circular through holes corresponding to the rectangular through holes can be formed in the second bottom plate 221, thereby connecting them through bolts, which can effectively improve the stability of the connection between the second bottom plate 221 and the bearing plate 11.

At the same time, in order to improve the support effect of the connecting arm, a plurality of connecting arms can be arranged between the bottom plate and the clamping plate, thereby connecting the clamping plate through a plurality of connecting arms, which can provide better support force and connection effect for the secondary beam I-beam 4, thereby ensuring the stability of the connection between the second connecting assembly 22 and the first connecting assembly 21 and the secondary beam I-beam 4.

Thus, the first clamping plate 214 and the second clamping plate 224 on both sides and the web of the secondary beam I-beam 4 in the middle are firmly fixed together to form a stable whole.
