Description

Technical Field

[0001] This utility model relates to the technical field of T-type connectors, specifically to a T-type connector for fixing steel beams. Background Technology

[0002] A steel beam is a transverse structural member made of steel, commonly used in the construction of large buildings, industrial facilities, and transportation engineering projects. As a transverse member, steel beams bear the important task of load-bearing in building structures. They can withstand a large amount of pressure and tension, making the building structure stronger and more robust. They can also enhance the stiffness and stability of the entire structure. The stiffness of steel beams is sufficient to offset the effects of deformation and deflection caused by various loads, making the entire building more stable. At the same time, steel beams can make buildings taller. By increasing the number and spacing of steel beams and other supports, more and taller stories can be supported, thereby expanding the building's height. The functions and uses of steel beams have led to their widespread application in various fields.

[0003] During the construction process, steel beams are often fixedly installed between two concrete columns. T-shaped connectors are installed and fixed on the steel beams on both sides, and then the two ends of the steel beams are connected to the T-shaped connectors on both sides, thereby realizing the installation and fixation of the steel beams.

[0004] Existing T-type connectors include mounting plates and connecting plates. To avoid the impact of welding heat on the stability of chemical anchors during installation, the mounting plates and connecting plates need to be welded and fixed before installation. However, direct welding makes it difficult to accurately determine the corresponding positions of the mounting plates and connecting plates, and positioning deviations can easily cause installation difficulties and affect installation stability. Furthermore, if the weld seam falls off using only welding, there are no safety measures to prevent this, posing a certain safety hazard. Therefore, this utility model proposes a T-type connector for fixing steel beams, which is safer, more stable, and easier to use in engineering construction. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the prior art by providing a T-shaped connector for fixing steel beams, so as to make the T-shaped connector more stable and thus ensure the stability and safety of the steel beam connection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a T-shaped connector for fixing steel beams, comprising a mounting plate and a connecting plate, wherein the mounting plate and the connecting plate are inserted together, a mounting groove is provided on the mounting plate, a connecting part is provided below the connecting plate, the mounting groove and the connecting part cooperate, a slot is provided on the upper and lower sides of the connecting part, a connecting groove is provided on the inner sides of the upper and lower sides of the mounting groove, a spring is fixedly installed in the connecting groove, the other end of the spring is connected to a locking block, and the locking block and the locking groove are non-detachable.

[0007] Furthermore, the card block and the card slot are square in shape and fit together. A chamfer is provided at the junction of the upper and lower sides of the connecting part and the bottom surface. The thickness of the card block extending out of the connecting slot is not greater than the radius of the chamfer.

[0008] Furthermore, the mounting plate is welded and fixedly connected to the connecting plate at the junction.

[0009] Furthermore, the height of the connecting portion is not greater than the depth of the mounting groove.

[0010] Furthermore, after the connecting part is connected to the mounting groove, a recessed groove is formed at the mounting groove on the rear side of the mounting plate; the connecting part and the mounting groove are welded and fixedly connected in the recessed groove; the weld at the junction of the connecting part and the mounting groove is not higher than the height of the recessed groove.

[0011] Furthermore, the mounting plate is provided with a first mounting hole, which is matched with a chemical anchor on the concrete column; the connecting plate is provided with a second mounting hole, which is matched with a mounting hole on the steel beam by bolts.

[0012] The beneficial effects of this utility model are:

[0013] 1. The mounting groove and connecting part of this utility model serve a positioning function, making the relative position of the mounting plate and the connecting plate more accurate, avoiding the skewing and deviation that may easily occur when the mounting plate and the connecting plate are directly welded, and making it more convenient for subsequent construction.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0023] Embodiments of this utility model:

[0024] like Figure 1-5 As shown, in this embodiment, the T-shaped connector 2 is used for the installation and fixing of the steel beam 3 added between the concrete columns 1; the T-shaped connector 2 is fixedly installed on the two concrete columns 1 respectively, and then the two ends of the steel beam 3 are connected and fixed through the T-shaped connector 2 at both ends.

[0025] In this embodiment, the T-shaped connector 2 includes a mounting plate 21 and a connecting plate 22. The mounting plate 21 is fitted with the concrete column 1, and the connecting plate 22 is fitted with the steel beam 3. A first mounting hole 211 is provided on the mounting plate 21, through which a chemical anchor bolt on the concrete column 1 is fitted. A second mounting hole 221 is provided on the connecting plate 22, through which a bolt is fitted to one end of the steel beam 3. The mounting plate 21 and the connecting plate 22 are fixedly connected.

[0026] A mounting groove 212 is provided through the mounting plate 21, and a connecting part 222 is provided on the connecting plate 22. The mounting groove 212 and the connecting part 222 are inserted and engaged. The depth of the mounting groove 212 is greater than the height of the connecting part 222, so that after the mounting groove 212 and the connecting part 222 are engaged, a recessed groove 23 is formed on the back of the mounting plate 21.

[0027] A chamfered portion 2221 is provided at the junction of the upper and lower sides of the connecting portion 222 and the bottom surface. A slot 2222 is provided on the upper and lower sides of the connecting portion 222. A connecting slot 2121 is provided on the upper and lower sides of the mounting slot 212. A spring 2122 is fixedly connected in the connecting slot 2121. The other end of the spring 2122 is fixedly connected to the locking block 2123. The locking block 2123 and the slot 2222 are both square and cooperate with each other. The thickness of the locking block 2123 extending out of the connecting slot 2121 is not greater than the radius of the chamfered portion 2221.

[0028] The principle of this utility model is as follows:

[0029] In use, the mounting plate 21 and the connecting plate 22 (both mounting plate 21 and connecting plate 22 are made of steel plates) are first connected. During the process, the connecting part below the connecting plate 22 is aligned with the connecting groove 2121 on the mounting plate 21. The connecting part is gently tapped with a hammer or similar tool to make the connecting part and the connecting groove 2121 fully connected. Due to the chamfered parts 2221 on the upper and lower sides of the connecting part, the locking block 2123 can be pressed into the connecting groove 2121 during the downward movement of the connecting part. When the connecting part and the connecting groove 2121 are fully engaged, the locking groove 2222 and the locking block 2123 are engaged. Since both the locking block 2123 and the locking groove 2222 are square, once the locking block 2123 and the locking groove 2222 are connected, the two cannot be separated again.

[0030] To ensure the stability of the connection between the mounting plate 21 and the connecting plate 22, the mounting plate 21 and the connecting plate 22 are welded together before the T-shaped connector 2 is installed. The welding is done on both sides, at the contact points between the mounting plate 21 and the connecting plate 22 at the top and bottom of the mounting plate 21. The welding from both top and bottom further ensures the stability and reliability of the connection. The groove 23 is designed to prevent the weld from protruding on the back side of the mounting plate 21, which would affect the installation of the mounting plate 21 on the concrete column 1. For example, if the thickness of the mounting plate 21 is 10mm, the depth of the groove 23 is 5mm, and the thickness of the weld is 3mm, the weld protrusion on the back side of the mounting plate 21 can be avoided. At this point, the T-shaped connector 2 of this utility model is assembled.

[0031] Installation holes are drilled in the concrete column 1, and chemical anchors are pre-embedded in the installation holes. Then, the chemical anchors are connected to the first installation hole 211 on the installation plate 21 to realize the installation and fixation of the T-shaped connector 2 of this utility model. The chemical anchors are existing and will not be described in detail. Then, the steel beam 3 is connected to the second installation hole 221 on the connecting plate 22 by bolts.
