Description
Technical Field
[0001] The utility model relates to the field of steel structure connectors, and specifically relates to a building steel structure connector. Background Technique
[0002] Building steel structure connectors are key components for connecting steel structure members and are crucial for ensuring structural stability and safety. They come in a wide variety, including fasteners, non-fasteners, welded parts, and linkages, etc., each with its own characteristics and are widely used in various steel structure projects. When choosing a suitable connector, factors such as the stress environment, construction conditions, and economy need to be considered. With the continuous progress of building technology, connectors are developing towards the directions of lightweight, high strength, high durability, and easy construction, etc., to meet more complex engineering requirements.
[0003] Existing building steel structure connectors can firmly connect different steel structure members together to form a whole, thus ensuring structural stability and safety. However, in the actual use process, when the connector bolts two I-beams, there is a problem. Specifically speaking, due to the gravity factor of the two I-beams themselves or the poor accuracy of the external installation structure, the ends of the two I-beams often have an interleaved structure, resulting in the interleaving of the through-hole positions of the connector and the I-beams, reducing the convenience of bolt connection. Content of the Utility Model
[0004] Based on this, the purpose of the utility model is to provide a building steel structure connector to solve the technical problem that there are many through-holes between the workpiece and the connector and they are not easy to align.
[0005] To achieve the above purpose, the utility model provides the following technical solution: a building steel structure connector, including a first plate, a second plate, and a third plate. Four limit holes are opened on the surfaces of the first plate and the third plate. An upper fixing part is arranged at the top of the first plate, and a lower fixing part is arranged at the bottom of the third plate. Four first mounting plates are arranged at the bottom of the upper fixing part, and four second mounting plates are arranged at the top of the lower fixing part. Four limit insertion rods are arranged inside both the upper fixing part and the lower fixing part.
[0006] By adopting the above technical solution, when two I-beams need to be fixed with a connecting piece, first, place the upper fixing piece on the tops of the two first plates and use a tool to tap it, so that the inner limiting insertion rods are gradually inserted into the limiting holes on the surfaces of the first plates. This step limits the positions of the two first plates through the four limiting insertion rods, aligns their through holes with the through holes on the upper fixing piece, and then, use the mounting bolts to penetrate and connect to complete the installation of the upper fixing piece. At the same time, similarly, install the lower fixing piece at the bottoms of the two third plates, place the side plates on both sides of the second plate, and use the mounting bolts to connect the side plates to the second plate. Finally, connect and fix the first mounting plate and the second mounting plate through the mounting bolts and the mounting holes to complete the overall connection operation. During this process, the insertion and limitation of the limiting insertion rods and the limiting holes, as well as the abutting limitation of the first mounting plate and the second mounting plate on the two I-beams, jointly ensure that the through hole positions of the upper fixing piece, the lower fixing piece, and the first plate and the third plate are opposite, thereby improving the convenience of bolt connection.
[0007] Further, the limiting insertion rods are inserted and engaged with the limiting holes, and the ends of the limiting insertion rods are in a sharp cone structure.
[0008] By adopting the above technical solution, the insertion and engagement of the limiting insertion rods and the limiting holes achieve precise limitation of the positions of the first plate and the third plate. This insertion method ensures that during the installation process of the upper fixing piece and the lower fixing piece, the two plates can remain relatively stable and will not shift or be misaligned.
[0009] Further, mounting holes are provided on both the first mounting plate and the second mounting plate, and the first mounting plate and the second mounting plate are in a detachable connection structure through the mounting holes and the mounting bolts.
[0010] By adopting the above technical solution, the mounting holes first provide a necessary channel for the mounting bolts, enabling the first mounting plate and the second mounting plate to be detachably connected through the mounting bolts. This detachable connection structure has significant advantages during the connection process of the I-beams. It not only simplifies the installation steps, improves the installation efficiency, but also makes it more convenient and fast when the connecting piece needs to be disassembled or replaced.
[0011] Further, mounting grooves are formed on the surfaces of the first mounting plate and the second mounting plate, and a tensiometer is installed inside the mounting grooves.
[0012] By adopting the above technical solution, an intuitive and real-time tensile force monitoring means is provided for the connecting piece. Through the tensiometer, users can easily understand the tensile force condition of the connecting piece under the stressed state, thereby judging whether the connection is firm and whether there are potential risks such as overload.
[0013] Furthermore, a plurality of through holes are formed in the first plate, the second plate, and the third plate, and are arranged in a rectangular array.
[0014] By adopting the above technical solution, the through holes arranged in a rectangular array provide multiple connection points for the connecting piece, so that when connecting the I-beam, multiple through holes can be connected according to the actual situation, thereby improving the connection stability.
[0015] Furthermore, side plates are provided on both sides of the second plate, and the side plates are bolted to the second plate through the through holes.
[0016] By adopting the above technical solution, the structural strength of the second plate is enhanced. The setting of the side plates effectively increases the side support of the second plate, enabling it to better resist deformation when stressed and improving the overall stability.
[0017] Furthermore, the upper fixing piece and the lower fixing piece are respectively bolted to the first plate and the third plate through the through holes.
[0018] By adopting the above technical solution, a firm connection between the connecting piece and the I-beam is ensured. Through the bolts passing through the through holes and being tightened, the upper fixing piece and the lower fixing piece can closely fit on the first plate and the third plate, and are not easily loosened or detached, thereby improving the overall stability and reliability of the connecting piece.
[0019] In summary, the present utility model mainly has the following beneficial effects:
[0020] 1. In the present utility model, through the upper fixing piece and the lower fixing piece, when two I-beams need to be fixed by a connecting piece, first, place the upper fixing piece on the tops of the two first plates and use a tool to tap it, so that the inner limiting insertion rods gradually insert into the limiting holes on the surface of the first plate. This step limits the positions of the two first plates through the four limiting insertion rods, aligns their through holes with the through holes on the upper fixing piece, and then uses the installation bolts to penetrate and connect to complete the installation of the upper fixing piece. At the same time, install the lower fixing piece in the same way. Finally, connect and fix the first mounting plate and the second mounting plate through the installation bolts to complete the overall connection operation. During this process, the insertion and limitation of the limiting insertion rods in the limiting holes and the abutment and limitation of the mounting plate on the I-beam together improve the convenience of the bolt connection;
[0021] 2. In the present utility model, by setting a tensiometer, as the service life of the I-beam increases, due to the pressure of the external load, the I-beam may be bent to varying degrees, causing the connecting piece to deform and exerting a certain pulling force on the inner tensiometer. At this time, the tensiometer can provide an intuitive manifestation of the bending degree of the I-beam for the operator, thereby improving the convenience of repair of the I-beam connecting piece and the repair convenience.

[0030] The embodiments of the present utility model will be described below according to its overall structure.
[0031] Embodiment 1:
[0032] A building steel structure connector, as Figures 1 - 4 shown, includes a first plate 1, a second plate 2, and a third plate 3. Four limiting holes 5 are provided on the surfaces of the first plate 1 and the third plate 3. An upper fixing member 4 is provided at the top of the first plate 1, and a lower fixing member 8 is provided at the bottom of the third plate 3. Four first mounting plates 6 are provided at the bottom of the upper fixing member 4, and four second mounting plates 7 are provided at the top of the lower fixing member 8. Four limiting insertion rods 9 are provided on the inner sides of the upper fixing member 4 and the lower fixing member 8. When two I-beams need to be fixed by a connector, first, place the upper fixing member 4 on the tops of the two first plates 1 and use a tool to strike it, so that the limiting insertion rods 9 on the inner side are gradually inserted into the limiting holes 5 on the surface of the first plate 1. This step limits the positions of the two first plates 1 by the four limiting insertion rods 9, making their through holes 15 aligned with the through holes 15 on the upper fixing member 4. Subsequently, use mounting bolts 13 to penetrate and connect to complete the installation of the upper fixing member 4. At the same time, similarly install the lower fixing member 8 at the bottoms of the two third plates 3, place the side plates 14 on both sides of the second plate 2, and use the mounting bolts 13 to connect the side plates 14 to the second plate 2. Finally, connect and fix the first mounting plate 6 and the second mounting plate 7 through the mounting bolts 13 and the mounting holes 10 to complete the overall connection operation. During this process, the insertion and limitation of the limiting insertion rods 9 and the limiting holes 5, as well as the abutting and limitation of the first mounting plate 6 and the second mounting plate 7 on the two I-beams, jointly ensure that the through hole 15 positions of the upper fixing member 4, the lower fixing member 8, the first plate 1, and the third plate 3 are opposite, thereby improving the convenience of bolt connection and greatly enhancing the installation convenience of the connector.
[0033] Refer to Figure 2 、 Figure 3, the limit insertion rod 9 is inserted and engaged with the limit hole 5. The end of the limit insertion rod 9 is in a tapered structure. The insertion and engagement of the limit insertion rod 9 with the limit hole 5 achieve precise limitation of the positions of the first plate 1 and the third plate 3. This insertion method ensures that during the installation process of the upper fixing member 4 and the lower fixing member 8, the two plates can remain relatively stable without offset or misalignment. At the same time, the end of the limit insertion rod 9 is in a tapered structure, making the insertion rod more smooth when inserted into the limit hole 5, reducing the resistance during insertion, and improving the installation convenience. The tapered structure also helps the limit insertion rod 9 to more easily penetrate the small protrusions or unevenness on the surface of the plate during the knocking process, so as to achieve a more tight insertion and engagement. In summary, the insertion and engagement of the limit insertion rod 9 with the limit hole 5, as well as the tapered structure of the end of the limit insertion rod 9, jointly improve the installation efficiency and stability of the connector, providing a more reliable and convenient solution for the connection of I-beams.
[0034] Refer to Figure 1 , Figure 3 , Figure 4 , mounting holes 10 are provided on both the first mounting plate 6 and the second mounting plate 7. The first mounting plate 6 and the second mounting plate 7 are in a detachable connection structure through the mounting holes 10 and mounting bolts 13. The mounting holes 10 first provide a necessary channel for the mounting bolts 13, enabling the first mounting plate 6 and the second mounting plate 7 to be detachably connected through the mounting bolts 13. This detachable connection structure has significant advantages in the connection process of I-beams. It not only simplifies the installation steps and improves the installation efficiency, but also makes the connector more convenient and fast when disassembly or replacement is required. At the same time, due to the standardization of the mounting holes 10 and the mounting bolts 13, this connection structure also has good versatility and replaceability, reducing the maintenance and replacement costs. In summary, the design of providing mounting holes 10 on the first mounting plate 6 and the second mounting plate 7 and forming a detachable connection structure through the mounting holes 10 and the mounting bolts 13 provides a more flexible and efficient solution for the connection of I-beams.
[0035] Embodiment 2:
[0036] Refer to Figure 1 , Figure 3 , Figure 4, on the surfaces of the first mounting plate 6 and the second mounting plate 7, mounting grooves 12 are provided, and a tensiometer 11 is installed inside the mounting grooves 12, providing an intuitive and real-time means of tensile force monitoring for the connecting piece. Through the tensiometer 11, users can conveniently understand the tensile force condition of the connecting piece under the stressed state, so as to judge whether the connection is firm and whether there are potential risks such as overload. At the same time, since the tensiometer 11 is installed inside the mounting groove 12, it also plays a role in protecting the tensiometer 11, avoiding its direct interference or damage by the external environment during use. In summary, the provision of the mounting grooves 12 on the first mounting plate 6 and the second mounting plate 7 and the installation of the tensiometer 11 not only improve the functionality of the connecting piece, but also enhance its safety and reliability in use.
[0037] Refer to Figure 1 , Figure 2 , Figure 3 , on the first plate 1, the second plate 2, and the third plate 3, a plurality of through holes 15 are provided, and they are arranged in a rectangular array. The arrangement of the through holes 15 in a rectangular array provides multiple connection points for the connecting piece, enabling multiple through holes 15 to be connected according to the actual situation when connecting the I-beam, thereby improving the connection stability. At the same time, the arrangement of the through holes 15 in a rectangular array not only makes the distribution of the connection points on the plate more uniform, contributing to enhancing the overall stability of the connecting piece, but also facilitates alignment and calibration during installation, simplifying the installation steps. In summary, the provision of a plurality of through holes 15 arranged in a rectangular array on the first plate 1, the second plate 2, and the third plate 3 provides a more stable and flexible solution for the connection of the I-beam.
[0038] Refer to Figure 1 , Figure 2 , on both sides of the second plate 2, side plates 14 are provided. The side plates 14 are bolted to the second plate 2 through the through holes 15, enhancing the structural strength of the second plate 2. The provision of the side plates 14 effectively increases the lateral support of the second plate 2, enabling it to better resist deformation when stressed and improving the overall stability. At the same time, the method of bolt connection through the through holes 15 with the second plate 2 not only simplifies the installation process, making the disassembly and assembly of the side plates 14 more convenient and rapid, but also helps to improve the fastening degree and reliability of the connection. In summary, the design of providing side plates 14 on both sides of the second plate 2 and realizing bolt connection with it through the through holes 15 provides stronger structural support and a more stable connection method for the connecting piece.
[0039] Refer to Figure 1 , Figure 2 , Figure 3, both the upper fixing member 4 and the lower fixing member 8 are bolted to the first plate 1 and the third plate 3 respectively through the through holes 15, ensuring a firm connection between the connecting member and the I-beam. By passing bolts through the through holes 15 and tightening them, the upper fixing member 4 and the lower fixing member 8 can closely adhere to the first plate 1 and the third plate 3, being not prone to loosening or falling off, thereby improving the overall stability and reliability of the connecting member. At the same time, this bolt connection method is also convenient for installation and disassembly. When it is necessary to adjust or replace the connecting member, the disassembly and assembly work can be quickly completed, improving the work efficiency. In summary, the upper fixing member 4 and the lower fixing member 8 are bolted to the first plate 1 and the third plate 3 through the through holes 15, providing a more stable and convenient solution for the connection of I-beams.
[0040] The implementation principle of the present utility model is as follows: When two I-beams need to be fixed by a connecting member, first place the upper fixing member 4 on the tops of the two first plates 1, and use tools such as a hammer to strike the upper fixing member 4. With the gradual striking, the inner limiting insertion rods 9 gradually insert into the limiting holes 5 on the surface of the first plate 1. At this time, due to the position limitation of the two first plates 1 by the four limiting insertion rods 9, it is beneficial to make the through holes 15 on the surfaces of the two first plates 1 and the through holes 15 on the upper fixing member 4 gradually align in position one by one. Subsequently, use the mounting bolts 13 to penetrate and connect them, thereby completing the installation operation of the upper fixing member 4. Similarly, install the lower fixing member 8. Then, place the side plates 14 on both sides of the second plate 2, and use the mounting bolts 13 to install and connect them. After that, use the mounting bolts 13 to connect and fix the first mounting plate 6 and the second mounting plate 7 through the mounting holes 10 to complete the connection operation of the whole connecting member to the two I-beams. During this connection process, by using the insertion and limitation of the limiting insertion rods 9 and the limiting holes 5, and the abutting limitation of the first mounting plate 6 and the second mounting plate 7 on the two I-beams, the through holes 15 of the upper fixing member 4, the lower fixing member 8 and the first plate 1, the third plate 3 are made to be in relative positions, thereby improving the convenience of bolt connection and greatly enhancing the usability of the connecting member.
