Description
Technical Field
[0001] This utility model relates to the field of armor joint technology, and in particular to an armor joint for the interface of diamond abrasive concrete floor. Background Technology
[0002] An armored joint is a structural component widely used in concrete flooring projects. It is typically installed between large concrete slabs to form expansion joints or deformation joints. Its main function is to separate concrete surface layers, release stress concentration caused by temperature changes, loads, or drying shrinkage, and prevent irregular cracks from forming in the concrete slabs. At the same time, the armored joint can provide reliable protection and force transmission at the edges of the slabs, ensuring that adjacent slabs remain flat and stable under vehicle loads or impacts. Therefore, it has important application value in heavy-duty flooring projects such as industrial plants, warehousing and logistics facilities, and transportation hubs.
[0003] Existing concrete floor armor joints typically rely on welding to fix and connect various components. The welding quality is greatly affected by the construction environment and the skill level of the operators. Moreover, once loosening or damage occurs, subsequent maintenance and replacement are difficult, making quick and reliable prefabricated installation impossible. In addition, existing armor joints generally use a single steel plate as the force transmission plate. Although it can play a certain role in load-bearing and force transmission, it lacks an effective elastic buffer under heavy impact, making it difficult to absorb impact energy and easily causing local cracking or spalling of the concrete. Furthermore, the rigid contact between the steel plate and the concrete will also generate a large impact noise when vehicles pass through the gap, affecting the comfort of the usage environment.
[0004] Therefore, this utility model proposes an armored joint for the interface of a corundum concrete floor. Utility Model Content
[0005] Based on this, in order to overcome the problems that existing concrete floor armor joints are mostly fixed by welding, construction is greatly affected by the environment and personnel, and later maintenance and replacement are difficult, making it difficult to achieve prefabricated installation. At the same time, they generally only use a single steel plate as the force transmission plate, which lacks elastic buffering, is difficult to absorb impact energy, and is prone to concrete cracking. Furthermore, due to rigid contact, it generates a lot of noise when vehicles pass through the joints, resulting in poor user comfort.
[0006] The technical solution of this utility model is as follows: an armored joint for the interface of a corundum concrete floor, comprising a pre-embedded steel plate, a protective flat steel, and a telescopic sheath; a connecting steel plate is fixedly connected to the top of the pre-embedded steel plate, the connecting steel plate is symmetrically installed near both sides of the pre-embedded steel plate, the protective flat steel is fixedly connected to the side of the connecting steel plate away from the pre-embedded steel plate, a force-transmitting plate is engaged and connected inside the pre-embedded steel plate, the force-transmitting plate is located near the center of the pre-embedded steel plate, and the telescopic sheath is movably connected to the side of the pre-embedded steel plate, the telescopic sheath is slidably sleeved on the outer wall of the force-transmitting plate.
[0007] Preferably, the embedded steel sheet has an L-shaped structure, the protective flat steel is symmetrically distributed on both sides of the embedded steel sheet, and the load-bearing plate passes through the embedded steel sheet.
[0008] Preferably, the embedded steel sheet is fixedly connected to a connecting seat on the side away from the telescopic sheath, and the connecting seats are symmetrically installed near the force transmission plate. The embedded steel sheet and the connecting seat are an integrated structure.
[0009] Preferably, a connecting shell is fixedly connected inside the connecting seat, and a locking collar is fixedly connected inside the connecting shell. The locking collar is located near the connecting seat, and a locking member is threadedly connected inside the connecting shell. The locking member is located away from the connecting seat.
[0010] Preferably, one end of the locking member is tightly attached to the end of the locking collar away from the connecting seat, and the other end of the locking member is fixedly connected to a rotating ring, which is located on the outside of the connecting shell.
[0011] Preferably, anchor bars are fixedly connected to the outer side of the connecting steel plate, and the anchor bars are symmetrically installed near both ends of the connecting steel plate. Connecting bolts are movably connected inside the connecting steel plate, and the connecting bolts are located near the center of the connecting steel plate.
[0012] Preferably, a damping plate is fixedly connected to the bottom of the force transmission plate. The damping plate has a honeycomb structure. A lower force transmission plate is fixedly connected to the side of the damping plate away from the force transmission plate. A support is fixedly connected to the side of the force transmission plate. The support is symmetrically installed on both sides of the force transmission plate. A connecting rod is hinged to the side of the support near the pre-embedded steel sheet. The connecting rod is slidably connected to the inner wall of the locking collar and the locking member.
[0013] The beneficial effects of this utility model are: 1. When the device is assembled, align the upper force plate and the lower force plate and insert the pre-embedded steel plate. The support drives the connecting rod to gradually insert into the connecting shell until the connecting rod is fully embedded. At this time, the upper force plate and the lower force plate reach the designated position. Then, rotate the rotating ring, and the locking part moves inward along the thread of the connecting shell and compresses the locking collar. After being compressed, the locking collar contracts towards the connecting rod, forming a locking effect similar to an expansion screw, thereby stably fixing the upper force plate and the lower force plate and realizing the snap-fit connection of the device without welding. 2. During the use of the device, the upper force plate, damping plate, and lower force plate together form a sandwich-like composite structure. When the protective flat steel is subjected to heavy impact, the impact force is transmitted to the upper force plate through the connecting steel plate and the embedded steel sheet. The middle rubber damping plate adopts a honeycomb structure, which can undergo elastic deformation, absorb impact energy, and reduce the peak impact force transmitted to the concrete, so as to transform rigid collision into flexible contact, thereby reducing the stress on the upper and lower force plates. At the same time, the rubber damping plate has a sound absorption effect, so it can effectively reduce the noise when vehicles pass through the gap, thus completing the vibration reduction and noise reduction process of the entire device.

[0020] Please see Figures 1-7 This utility model provides a technical solution: an armored joint for the interface of a corundum concrete floor, comprising a pre-embedded steel plate 1, a protective flat steel 3, and a telescopic sheath 5; a connecting steel plate 2 is fixedly connected to the top of the pre-embedded steel plate 1, the connecting steel plate 2 is symmetrically installed near both sides of the pre-embedded steel plate 1, the protective flat steel 3 is fixedly connected to the side of the connecting steel plate 2 away from the pre-embedded steel plate 1, a force transmission plate 4 is engaged and connected inside the pre-embedded steel plate 1, the force transmission plate 4 is located near the center of the pre-embedded steel plate 1, and the telescopic sheath 5 is movably connected to the side of the pre-embedded steel plate 1, and the telescopic sheath 5 is slidably sleeved on the outer wall of the force transmission plate 4.
[0021] The embedded steel sheet 1 has an L-shaped structure, and the protective flat steel 3 is symmetrically distributed on both sides near the embedded steel sheet 1. The load transfer plate 4 passes through the embedded steel sheet 1. The L-shaped embedded steel sheet 1 can better disperse and transfer the stress from the vehicle or external load, and enhance the overall stability of the ground joint. The load transfer plate 4 and the embedded steel sheet 1 form a reliable connection to ensure that the impact force can be efficiently transferred to the entire composite structure.
[0022] A connecting seat 101 is fixedly connected to the side of the pre-embedded steel plate 1 away from the telescopic sheath 5. The connecting seat 101 is symmetrically installed near the force transmission plate 4. The pre-embedded steel plate 1 and the connecting seat 101 are an integrated structure. The integrated structure of the pre-embedded steel plate 1 and the connecting seat 101 directly enhances the overall strength of the device. The symmetrically installed connecting seat 101 makes the force on both sides balanced, avoiding tilting or torsion caused by eccentric force.
[0023] A connecting shell 102 is fixedly connected inside the connecting base 101, and a locking collar 103 is fixedly connected inside the connecting shell 102. The locking collar 103 is located close to the connecting base 101. A locking member 104 is threaded inside the connecting shell 102. The locking member 104 is located away from the connecting base 101. The locking collar 103 can directly act on the subsequent connecting components when locking. At the same time, the locking collar 103 is made of elastic rubber material, which can form a stable lock after compression, and can also buffer impact and avoid rigid friction damage.
[0024] One end of the locking member 104 is tightly attached to the end of the locking collar 103 away from the connecting seat 101, and the other end of the locking member 104 is fixedly connected to a rotating ring 105. The rotating ring 105 is located on the outside of the connecting shell 102. The rotating ring 105 drives the locking member 104 to move along the connecting shell 102 in a threaded manner, so that it continuously presses against the locking collar 103.
[0025] Anchor bars 201 are fixedly connected to the outer side of the connecting steel plate 2. The anchor bars 201 are symmetrically installed near both ends of the connecting steel plate 2. Connecting bolts 202 are movably connected inside the connecting steel plate 2. The connecting bolts 202 are located near the center of the connecting steel plate 2. The anchor bars 201 increase the bonding area between the connecting steel plate 2 and the concrete, thereby improving the anchoring force. The anchor bars 201 provide a firm concrete anchorage, and the connecting bolts 202 provide a detachable fastening. The combination of the two ensures the strength and stability of the structure.
[0026] A damping plate 401 is fixedly connected to the bottom of the force transmission plate 4. The damping plate 401 has a honeycomb structure. A lower force transmission plate 402 is fixedly connected to the side of the damping plate 401 away from the force transmission plate 4. A support 403 is fixedly connected to the side of the force transmission plate 4. The supports 403 are symmetrically installed on both sides of the force transmission plate 4. A connecting rod 404 is hinged to the side of the support 403 near the embedded steel sheet 1. The connecting rod 404 is slidably connected to the inner wall of the locking collar 103 and the locking member 104. The honeycomb structure of the damping plate 401 is lighter, has better buffering performance, and can improve deformation recovery ability.
[0027] Working principle: See Figures 1-5As shown, when the device begins to be assembled, firstly, the upper force plate 4 and the lower force plate 402 are aligned and the pre-embedded steel plate 1 is inserted. The support 403 moves synchronously with the upper force plate 4, driving the connecting rod 404 to gradually insert into the connecting shell 102 on the connecting seat 101 until the connecting rod 404 is fully embedded. At this time, the upper force plate 4 and the lower force plate 402 reach the designated position. Then, the rotating ring 105 is held and rotated by external force. The locking part 104 moves inward along the thread of the connecting shell 102 and compresses the locking collar 103. Since the locking collar 103 is made of rubber, it has a certain elasticity. After being compressed, it contracts towards the connecting rod 404, forming a locking effect similar to an expansion screw, thereby stably fixing the upper force plate 4 and the lower force plate 402 and realizing the snap-fit connection of the device. See Figure 1 As shown, after the device is assembled, the entire device is first placed in the construction area and covered with concrete so that the pre-embedded steel plate 1, the load transfer plate 4 and the telescopic sheath 5 are completely buried in the concrete ground, thus completing the installation preparation. See Figures 3-7 As shown, during the use of the device, the upper force plate 4, damping plate 401, and lower force plate 402 together form a sandwich-like composite structure. When the protective flat steel 3 is subjected to heavy impact, the impact force is transmitted to the upper force plate 4 through the connecting steel plate 2 and the embedded steel sheet 1. The middle rubber damping plate 401 adopts a honeycomb structure, which can undergo elastic deformation, absorb impact energy, and reduce the peak impact force transmitted to the concrete, so as to transform rigid collision into flexible contact, thereby reducing the stress on the upper force plate 4 and the lower force plate 402. At the same time, the rubber damping plate 401 has a sound absorption effect, so it can effectively reduce the noise when the vehicle passes through the gap. Meanwhile, when the upper force plate 4 moves up and down, the support 403 follows synchronously. Since the support 403 and the connecting rod 404 are hinged, the connecting rod 404 remains stable in the connecting shell 102, continuously ensuring the reliable engagement of the upper force plate 4 and the embedded steel sheet 1, thereby completing the vibration reduction and noise reduction process of the entire device.
[0028] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
