Description

Technical Field

[0001] This application relates to the field of ground armor stitching devices, and more particularly to an armor stitching device. Background Technology

[0002] An armored joint system is a protective device applied to monolithic flooring. It utilizes pre-existing gaps to accommodate expansion and contraction of the building structure or flooring caused by factors such as temperature changes, vibration, and settlement. By incorporating armored joints at structural joints, stress concentration is effectively reduced, preventing cracks, damage, and deformation. Armored joints typically consist of materials such as metal plates and foam boards. The metal plates provide structural strength, while the foam boards act as fillers and buffers, protecting the floor edges from crushing and abrasion. During construction, armored joints can also be used as formwork, improving construction efficiency and reducing subsequent maintenance costs.

[0003] Traditional armor-type joints come in three types: straight, zigzag, and S-shaped. Among these, the straight-type joint has a weak bond between the concrete and the vertical plate. Under external forces, the vertical plate easily deforms and detaches, losing its protective function. The zigzag-type joint, because the finished joint is also zigzag, forms sharp angles at the corners, which are weak points in the concrete and prone to damage under external forces. The S-shaped joint has a curved vertical plate throughout, meaning the tensile force transmitted along the curve is not on the same plane as the plate. Therefore, traditional armor-type joints are insufficient to effectively protect the floor surface. Summary of the Invention

[0004] This application discloses an armor joint device. Compared with traditional armor joints, this armor joint can replace the construction template when set at the construction joint of the ground compartment method. After construction is completed, the armor vertical plate is tightly bonded to the concrete at the joint edge, and the force is directly transmitted, providing good protection for the weak parts of the concrete edge.

[0005] To achieve the above objectives, embodiments of this application disclose an armor sewing device, comprising:

[0006] Dividing vertical plate, the dividing vertical plate is set perpendicular to the ground between the two zones;

[0007] An armor plate assembly is provided on and connected to the dividing vertical plate in a direction perpendicular to the ground. The armor plate assembly includes two armor plates, which are spaced apart in a direction parallel to and perpendicular to the dividing vertical plate to form armor seams. The two armor plates are connected by easily broken rivets. Each armor plate includes multiple planar segments and multiple arc-shaped segments. The multiple planar segments are arranged along the length of the dividing vertical plate, and adjacent planar segments are at a preset angle and smoothly connected by the arc-shaped segments.

[0008] As an optional implementation, the plurality of preset included angles are equal.

[0009] As an optional implementation, the preset included angle is 100°-120°.

[0010] As an optional implementation, the plurality of planar segments have equal lengths, and the plurality of arc segments have equal lengths.

[0011] As an optional implementation, the radius of the arc segment is greater than 30mm and not greater than the distance between the two armor vertical plates.

[0012] As an optional implementation, the thickness of the armor vertical plate is not less than 6mm, and the height is 50mm-80mm.

[0013] As an optional implementation, the armor stitching device further includes a plurality of anchor rods connected to the vertices of the plurality of arc segments, the plurality of anchor rods being inclined downward in the vertical direction.

[0014] As an optional implementation, the plurality of anchor rods are inclined downward at an angle of 15°-20° in the vertical direction.

[0015] As an optional implementation, the armor seam device further includes a force transmission rod. The dividing vertical plate has multiple force transmission holes along its length. The multiple force transmission holes are spaced apart. The force transmission rod passes through the force transmission holes and connects to the concrete in the two sections.

[0016] As an optional implementation, the spacing between the plurality of force transmission holes is 300mm-400mm.

[0017] Compared with the prior art, the beneficial effects of this application are:

[0018] This application embodiment sets multiple arc-shaped segments and multiple planar segments, with the arc-shaped segments spaced apart and adjacent arc-shaped segments connected by planar segments. The directions of adjacent arc-shaped segments are opposite to each other. This achieves the following: Firstly, relative to the zigzag armor seam of the armor vertical plate, the concrete edge of the armor seam will not have sharp corners or weak points, and the armor vertical plate will not experience unfavorable out-of-plane tensile forces. Secondly, relative to the S-shaped sine wave armor seam of the armor vertical plate, the armor seam is straight except for the chamfered crest, resulting in more direct force application.

[0033] Armored joints are a construction technique that uses pre-existing gaps in the floor or building structure to allow materials to expand and contract freely under conditions such as temperature changes, vibration, or settlement, thereby reducing structural stress and preventing cracking. Armored joints are typically constructed from materials such as metal plates and foam boards. The metal plates provide structural support, while the foam boards act as fillers and cushioning, protecting the edges of the floor from damage. During construction, armored joints can also be used as formwork, improving construction efficiency and reducing maintenance costs.

[0034] Please see Figures 1 to 3 , Figure 1 The armor's vertical plates are straight-line type in related technologies; Figure 2 The vertical plate of the armor in the related technology is a zigzag shape; Figure 3The S-sine wave shape is used for the armor vertical plate in related technologies. Traditional armor seams are classified into three types: straight armor vertical plate, zigzag armor vertical plate, and S-sine wave armor vertical plate. Among them, the straight armor seam has insufficient bonding strength between the concrete edge and the vertical plate. Under external force, the vertical plate is prone to deformation or detachment from its original position, losing its protective function for the concrete edge and greatly reducing its protective effectiveness. After the zigzag armor seam is formed, the seam edge will form a bend. These bends are weak points in the concrete structure and are prone to damage under external force, thereby reducing the stability and durability of the seam edge. The S-sine wave armor seam is designed as a curve to avoid bends, but the tensile force transmission is not on the same plane as the plate surface, resulting in uneven stress distribution, affecting its protective effect and structural stability.

[0035] Based on this, the present application discloses an armor seam device in which the armor vertical plate is tightly bonded to the seam edge concrete, and the force is directly transmitted, providing good protection for the weak parts of the concrete edge.

[0036] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0037] Please see Figure 4 , Figure 4 This is a schematic diagram of the structure of the armor stitching device 100 in this application;

[0038] This application discloses an armor sewing device 100, which includes:

[0039] Dividing vertical plate 11, the dividing vertical plate 11 is set perpendicular to the ground between the two zones;

[0040] Armor vertical plate assembly 12 is disposed on and connected to the dividing vertical plate 11 in a direction perpendicular to the ground. Armor vertical plate assembly 12 includes two armor vertical plates 121. The two armor vertical plates 121 are spaced apart in a direction parallel to and perpendicular to the dividing vertical plate 11 to form armor seams 13. The two armor vertical plates 121 are connected by easy-break rivets 14. Armor vertical plate 121 includes multiple planar segments 1211 and multiple arc segments 1212. The multiple planar segments 1211 are arranged along the length direction of the dividing vertical plate 11. Adjacent two planar segments 1211 are at a preset included angle 122 and are smoothly connected by the arc segments 1212.

[0041] Firstly, this embodiment employs the ground-level compartmentalized construction method. Compartmentalized construction is a building engineering technique primarily used to control cracks in concrete structures caused by shrinkage, temperature changes, and other factors during hardening and use. By dividing a large concrete structure into several smaller construction areas—compartments—stress within these areas can be effectively managed and released, thereby reducing the generation and development of cracks. Compartmentalized construction helps improve the overall integrity and durability of the structure. Secondly, by setting two armor vertical plates 121, the armor seam 13 can more effectively disperse and transfer stress, avoiding stress concentration, thereby enhancing structural stability and reducing the occurrence of cracks and damage. By setting multiple curved sections 1212 and multiple flat sections 1211, the edges of the armor seam 13 will not have sharp corners or weak points in the concrete. Except for the chamfered crest, the other parts are straight, resulting in more direct stress distribution. This ensures the protective effect of the armor seam 13 on the concrete, enhances the stability and durability of the structure, reduces structural wear and damage, lowers maintenance costs and frequency, and extends the service life of the floor. The new armor seam 13 design is more convenient to construct, as it can be used as a template, improving construction efficiency and reducing construction time and costs. In addition, because some plates are straight, the steel plate length is shorter, saving more materials.

[0042] Two armor vertical plates 121 are connected by easy-break rivets 14. The purpose of using easy-break rivets 14 in the armor seam 13 is to provide a predetermined break point. When the concrete in the two sections dries and shrinks, it will pull the easy-break rivets 14 off, separating the two armor vertical plates 121 to form the armor seam 13. The easy-break rivets 14 can protect the armor vertical plate assembly 12 and other structures from damage when they are pulled apart by the concrete, ensuring the integrity of the armor seam 13.

[0043] Please see Figure 6 , Figure 6 for Figure 4Another structural schematic diagram of the armor seam device 100 shows that multiple preset included angles are equal and range from 100° to 120°. If the preset included angle 122 is greater than 120°, the resulting armor seam 13 will be too straight, indistinguishable from a straight armor seam, making it difficult to increase the bond strength between the concrete and the armor vertical plate assembly 12. If the angle is less than 100°, while it can increase the bond strength between the concrete and the armor vertical plate assembly 12, it will waste more material, increasing manufacturing costs and difficulty. Within the 100°-120° range, stress can be more effectively transferred along the force transmission plate without causing excessive energy loss or stress concentration. This angle range is beneficial for balancing stress distribution, reducing stress concentration points, and thus improving the overall stability and durability of the structure. This angle design is easier to implement during construction and facilitates later maintenance and inspection. The selection of a standard angle helps standardize construction, reduces construction difficulty, and improves construction efficiency.

[0044] For details, please refer to Figure 6 Multiple planar segments 1211 are of equal length, and multiple curved segments 1212 are of equal length. The radius 1311 of the curved segment 1212 is greater than 30mm and not greater than the distance between two armor vertical plates 121. On the one hand, the radius 1311 of the curved segment 1212 being greater than 30mm ensures that the connection between two adjacent planar segments 1211 is distinct from the zigzag armor seam 13. If the radius 1311 is small, the shape of the armor seam 13 will resemble a zigzag line, making it difficult to avoid angles. On the other hand, the radius 1311 of the curved segment 1212 not being greater than the distance between two armor vertical plates 121 avoids material waste. Although this achieves the purpose of avoiding angles, if the radius 1311 is too large, the length of the curved segment 1212 will be longer, resulting in unnecessary waste and increasing the processing difficulty.

[0045] For details, please refer to Figure 6 The height of the two armor vertical plates 121 is 50mm-80mm. When the height of the armor vertical plate group 12 is less than 50mm, the concrete is difficult to crack in the predetermined direction, and the armor vertical plate group 12 is difficult to induce the concrete to crack. When the height of the armor vertical plate group 12 is greater than 80mm, the concrete can crack in the predetermined direction, but the excessive height wastes materials and increases costs.

[0046] For details, please refer to Figure 5 The thickness of the two armor vertical plates 121 is not less than 6mm. When the thickness is less than 6mm, it is difficult to provide sufficient support and bending and shear resistance. Thicker force transmission plates can better resist fatigue and corrosion, thereby extending the service life of the structure. They can also provide a larger section modulus, thereby improving the overall stiffness of the structure and making the structure more stable under stress.

[0047] In some embodiments, please refer to Figure 5 The armor stitching device 100 also includes a plurality of anchor rods 15, which are connected to the apex of a plurality of arc segments 1212, and the plurality of anchor rods 15 are inclined downward in the vertical direction. The use of multiple anchor bolts 15 in the armored joint 13 serves to provide additional structural stability and support. The anchor bolts 15 firmly connect the armored joint 13 to the concrete structure, enhancing its integrity and durability. This helps resist external forces such as vehicle loads, shrinkage and expansion caused by temperature changes, and other factors that could lead to structural damage. The distribution of multiple anchor bolts 15 ensures uniform support along the entire length of the armored joint 13, thereby improving the overall structural performance and safety. Specifically, the downward inclination of the multiple anchor bolts 15 at an angle of 15°-20° provides better structural anchoring. This design helps improve the pull-out resistance of the anchor bolts 15 because the inclined anchor bolts 15 can more effectively transfer forces to the stable soil layer. Furthermore, the inclined anchor bolts 15 provide greater friction, increasing the overall stability of the structure, especially in resisting horizontal forces and enhancing its anti-slip capability.

[0048] In some embodiments, please refer to Figure 5 The armor seam device 100 also includes a force transmission rod 16. The dividing vertical plate 11 has multiple force transmission holes along the length of the armor vertical plate group 12. The multiple force transmission holes are spaced apart. The force transmission rod 16 passes through the force transmission holes and connects with the concrete in the two sections. The distance between the multiple force transmission holes is 300mm-400mm.

[0049] On the one hand, the dowel bar 16, anchored in the concrete, can pull the joint apart when the concrete shrinks, expands, or settles unevenly, thus maintaining the integrity and functionality of the structure. On the other hand, the dowel bar 16 also has an overall force transmission function, which can transfer the load from one side to the other under vertical load, ensuring that the floor slabs on both sides of the expansion joint can work together and remain at the same level, avoiding the appearance of steps.

[0050] In some embodiments, please refer to Figure 5The armor seam assembly 100 also includes a temporary construction support 17, which is connected to the armor vertical plate assembly 12 to support the armor seam assembly 100. The temporary construction support 17, connected to the armor vertical plate assembly 12, provides stable support during the construction of the armor seam assembly 100, ensuring structural safety and smooth construction. This support helps maintain the shape and position of the armor seam assembly 100, preventing deformation or displacement due to its own weight or other external forces during concrete pouring and curing. Furthermore, the temporary construction support 17 helps distribute the load, reducing pressure on the armor seam assembly 100 itself, thereby improving overall construction quality and structural durability.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
