Description

Technical Field

[0001] This application relates to the field of building structure technology, specifically to a corrugated plate node connection device. Background Technology

[0002] In the field of steel structure and composite structure buildings, the corrugated section of corrugated plates can suppress local buckling of plates through out-of-plane constraints, and the corrugated fold deformation can absorb seismic energy. Therefore, corrugated plates have become the preferred component in beam-column joint design.

[0003] Traditionally, corrugated plates are connected by welding or bolts. However, welding connections rely on on-site hot work and are easily affected by the environment and the welding skills of the construction personnel. This may cause stress to concentrate in unqualified welds, creating hidden hazards. Bolt connections require pre-drilling holes in the components and applying high pre-tightening force to each bolt during construction. The complicated process results in low overall installation efficiency. Summary of the Invention

[0004] This application proposes a waveform board node connection device to solve the problems mentioned in the background art.

[0005] A corrugated plate node connection device includes a metal corrugated plate and a concrete slab, including an I-beam and a metal base plate support vertically welded and fixed to the top flange of the I-beam. A metal base is welded to the upper surface of the metal base plate support, and the metal base is vertically welded to the upper surface of the metal base plate support. The surface of the metal base has a base hole. The device also includes a pin vertically welded to the bottom surface of the crest of the metal corrugated plate. The lower end face of the pin has a 40°-50° chamfer. The metal base has a locking mechanism that cooperates with the pin.

[0006] Furthermore, the locking mechanism includes a pin channel provided on the surface of the base channel, in which a pin and a spring are nested, and the two ends of the spring are fixedly connected to the pin and the bottom of the pin channel, respectively.

[0007] Furthermore, a limiting ring is provided on the surface of the pin, and a limiting block is provided at the edge of the pin hole opening to restrict the movement of the limiting ring. A radially penetrating locking hole is opened on the surface of the corresponding position of the pin.

[0008] Furthermore, a mechanical locking mechanism is used directly between the pin and the metal base, replacing traditional welding and avoiding stress concentration in the weld. Simultaneously, the locking mechanism is prefabricated in the factory, mitigating fusion defects caused by variations in manual welding skill. Insertion of the pin triggers automatic locking, eliminating the need for tightening each bolt individually.

[0009] Furthermore, the pin holes are symmetrically distributed along the central axis of the base holes, and a tapered guide flare is provided at the top of the base holes to achieve blind insertion and alignment, thereby improving installation efficiency.

[0010] Furthermore, the insertion end of the pin is a hemispherical arc surface, and the pin hole and the inner surface of the lock hole are concave arc surfaces that are adapted to it.

[0011] Furthermore, a rubber buffer layer is provided between the metal base plate support and the top flange of the I-beam. The rubber buffer layer completely covers the bottom surface of the metal base plate support, absorbing seismic energy and reducing its transmission to the I-beam.

[0012] Furthermore, the rubber buffer layer is independently layered, and can be replaced individually after aging, avoiding the need to replace the entire node.

[0013] Furthermore, it also includes bolts to prevent the metal corrugated plate from loosening. The bolts penetrate the metal base plate support, the rubber buffer layer, and the top flange of the I-beam, and are secured by torque pre-tightening to press the three layers together.

[0014] Furthermore, it also includes a sealing cover assembly, which includes a joint angle iron fixed to the end side wall of the corrugated plate, with a mounting hole provided on one flange surface of the joint angle iron, and a joint steel plate covering the joint area between the corrugated plate and the metal base plate support, with a through hole opened at the flange end of the joint steel plate.

[0015] Furthermore, it also includes a joint steel pin that penetrates the mounting hole and the through hole, allowing the joint steel plate to rotate and achieve opening and closing coverage of the joint area; maintenance can be performed by opening the joint steel plate without cutting the concrete slab.

[0016] The metal corrugated plate, metal base, and joint steel plate are prefabricated in the factory.

[0017] During construction, the first step is to position the rubber buffer layer: lay the rubber buffer layer flat on the top flange of the I-beam, completely covering the bolt hole area;

[0018] Step 2: Fix the metal base plate support: Align the metal base plate support with the rubber buffer layer, and insert the anti-loosening bolts from top to bottom through the metal base plate support, the rubber buffer layer, and the top flange of the I-beam; pre-tighten in two stages with a torque wrench.

[0019] Step 3: Install the metal corrugated plate: Hoist the metal corrugated plate so that the chamfer of the pin is aligned with the tapered flare of the metal base. Press the corrugated plate down vertically, and the pin slides into the base channel along the tapered flare.

[0020] Under the preload of the spring, the hemispherical arc end of the pin protrudes to the inner wall of the base channel; the chamfer at the lower end of the pin and the tapered guide flare at the top of the base channel form a double-bevel guide structure, guiding the pin into the base channel; when the wave plate is pressed down, the chamfered bevel of the pin contacts the hemispherical arc surface of the pin, pushing the pin to move backward along the horizontal pin channel, while compressing the spring.

[0021] When the pin retracts, the limiting ring at its tail slides along the channel, and the spring is compressed. When the pin descends to the designed locking depth, the axis of the pin coincides with the center line of the radial lock hole on the side wall of the pin. The spring releases the stored potential energy, pushing the pin into the lock hole of the pin to achieve locking.

[0022] Step 4: Close the sealing cover;

[0023] Align the through holes of the joint steel plate flange with the mounting holes of the joint angle iron; insert the joint steel pin to pass through and complete the seal.

[0024] Compared with the prior art, this application has the following beneficial effects:

[0025] The pin-spring pin automatic locking mechanism replaces traditional welding and bolt connections. Inserting the pin into the base hole triggers the automatic mechanical locking mechanism, which, combined with the double-sloping guide structure, enables blind insertion, significantly improving installation efficiency and mitigating the risks of on-site welding defects. Simultaneously, a fully covered independent rubber buffer layer is installed between the support and the steel beam, effectively absorbing seismic impact energy, reducing energy transfer to the main structure, improving the overall seismic performance of the joint, and allowing for convenient maintenance as the rubber layer can be replaced individually after aging.

[0026] A rotatable sealing cover assembly covers the joint. During maintenance, simply rotating the cover allows for inspection or maintenance of the internal locking mechanism without damaging the upper concrete slab, greatly simplifying future maintenance. Furthermore, anti-loosening bolts are torque-pressed through the three-layer structure, providing foundation stability; core components are all prefabricated in the factory, ensuring machining accuracy and high reliability of the overall connection joint.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0036] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] like Figure 1-5 As shown, a corrugated plate node connection device includes a metal corrugated plate 104 and a concrete slab 105, an I-beam 101, and a metal base plate support 103 that is vertically fixed to the top flange of the I-beam 101. A metal base 123 is fixedly connected to the upper surface of the metal base plate support 103. The metal base 123 is perpendicular to the upper surface of the metal base plate support 103. A base hole 124 is opened on the surface of the metal base 123. It also includes a pin 121 that is vertically welded to the bottom surface of the crest of the metal corrugated plate 104. The lower end face of the pin 121 is provided with a 40°-50° chamfer. A locking mechanism that cooperates with the pin 121 is provided inside the metal base 123.

[0038] The locking mechanism includes a pin channel 125 disposed on the surface of the base channel 124. A pin 126 and a spring 122 are nested in the pin channel 125. The two ends of the spring 122 are fixedly connected to the bottom of the pin 126 and the pin channel 125, respectively.

[0039] The pin surface is provided with a limiting ring, the pin hole 125 opening edge is provided with a limiting block to restrict the movement of the limiting ring, and the corresponding position of the pin 121 is provided with a radially penetrating locking hole.

[0040] The mechanical locking mechanism, which directly engages the pin 121 with the metal base 123, replaces traditional welding and avoids stress concentration in the weld. Furthermore, the prefabricated locking mechanism in the factory mitigates fusion defects caused by variations in manual welding skill. Insertion of the pin 121 triggers automatic locking, eliminating the need for tightening each bolt individually.

[0041] The pin holes 125 are symmetrically distributed along the central axis of the base holes 124, and the top of the base holes 124 is provided with a tapered guide flare to achieve blind insertion and alignment, thereby improving installation efficiency.

[0042] The insertion end of the pin 126 is a hemispherical arc surface, and the pin channel 125 and the inner surface of the lock hole are concave arc surfaces that are adapted to it.

[0043] A rubber buffer layer 132 is provided between the metal base plate support 103 and the top flange of the I-beam 101. The rubber buffer layer 132 completely covers the bottom surface of the metal base plate support 103, absorbing seismic energy and reducing its transmission to the I-beam 101.

[0044] The rubber buffer layer 132 is independently layered and can be replaced individually after aging, avoiding the need to replace the entire node.

[0045] It also includes bolts 133 to prevent the metal corrugated plate 104 from loosening. The bolts 133 penetrate the metal base plate support 103, the rubber buffer layer 132 and the top flange of the I-beam 101, and are fixed by torque pre-tightening to press the three layers together.

[0046] It also includes a sealing cover assembly, which includes a joint angle iron 161 fixed to the end side wall of the corrugated plate. One flange surface of the joint angle iron 161 is provided with a mounting hole. It also includes a joint steel plate 162 covering the joint area between the corrugated plate and the metal base plate support 103. The flange end of the joint steel plate 162 is provided with a through hole.

[0047] It also includes a connector steel pin 163 that passes through the mounting hole and the through hole, so that the connector steel plate 162 can rotate to achieve opening and closing coverage of the joint area; maintenance can be carried out by opening the connector steel plate 162 without cutting the concrete slab 105.

[0048] The metal corrugated plate 104, the metal base 123, and the joint steel plate 162 are prefabricated in the factory.

[0049] During construction, the first step is to position the rubber buffer layer: lay the rubber buffer layer 132 flat on the top flange of the I-beam 101, completely covering the bolt hole area;

[0050] Step 2: Fix the metal base plate support 103: Align the metal base plate support 103 with the rubber buffer layer 132, and the anti-loosening bolts 133 pass through the metal base plate support 103, the rubber buffer layer 132 and the top flange of the I-beam 101 from top to bottom; pre-tighten in two stages with a torque wrench.

[0051] Step 3: Install the metal corrugated plate 104: Hoist the metal corrugated plate 104, aligning the 45° chamfer of the pin 121 with the tapered flare of the metal base 123, and press the corrugated plate down vertically. The pin will slide into the base channel 124 along the tapered flare.

[0052] Step 3: Install the metal corrugated plate 104: Hoist the metal corrugated plate 104 so that the 45° chamfer of the pin 121 is aligned with the tapered flare of the metal base 123. Press the corrugated plate down vertically and the pin 121 slides into the base channel 124 along the tapered flare.

[0053] Under the preload of spring 122, the hemispherical arc end of pin 126 slightly protrudes into the inner wall of base channel 124; the chamfer at the lower end of pin 121 and the tapered guide flare at the top of base channel 124 form a double-bevel guide structure; when wave plate 104 is pressed down, the chamfered bevel of pin 121 contacts the hemispherical arc of pin 126, pushing pin 126 to move outward along horizontal pin channel 125, while compressing spring 122;

[0054] When the pin 126 retracts, the limiting ring at its tail slides along the channel 2, and the spring 122 is compressed. When the pin 121 descends to the designed locking depth, the axis of the pin 126 coincides with the center line of the radial lock hole on the side wall of the pin. The spring 122 releases the stored potential energy and pushes the pin 126 into the lock hole of the pin to achieve locking.

[0055] Step 4: Close the sealing cover;

[0056] Align the flange through hole of the joint steel plate 162 with the mounting hole of the joint angle iron 161; insert the joint steel pin 163 to pass through and complete the seal.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
