Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to an armor seam device. Background Technology

[0002] The aforementioned armor joint, also known as a mortise joint or armor plate joint, is a structural induced joint with metal edging, pre-installed in large-area concrete floors, pavements, or floor slabs. For example, it is pre-assembled into standard components using edge-protecting angle steel and sliding load-bearing plates, and then embedded in the concrete. The core functions of the armor joint can be summarized by, but are not limited to, the following four elements: preventing random cracking of the floor and improving the overall integrity of the floor; inducing cracks to occur at predetermined locations; protecting the concrete edges of the joint and improving durability; and transferring loads between adjacent slabs.

[0003] Technical information related to the aforementioned armor-joint device can be found in publicly available Chinese patent documents. For example, CN221168516U recommends "An S-shaped armor-joint device for prestressing ultra-long seamless ground layers." This patent uses an S-shaped bending structure to absorb the shrinkage and deformation of prestressed concrete. See paragraph 0024 of the specification: "Two sets of S-shaped steel plates are close to each other on one side, with S-shaped curved surfaces aligned with each other." However, since the load is mainly dispersed through the deformation of the S-shaped curved surface, it remains relatively sensitive to stress concentration in local concrete areas. Another example is CN222140583U, which describes "A standard armor-joint component for large-area floor slabs." This patent emphasizes standardization and rapid installation. While it achieves the technical effects described in paragraph 0012 of the specification, it relies too heavily on concrete encapsulation for stability. Due to the lack of rationality in the overall structure, the dual anti-bending mechanism formed by the combination of the folding foot and wing plate is relatively weak in resisting the eccentric load of forklift wheels, making it prone to deformation or concrete crushing under complex stress conditions. Standard parts have protrusions or grooves, which affect passage and cleaning.

[0004] Based on the existing technical situation, it is of positive significance to explore armor seams that can make up for the deficiencies and make the structure more reasonable. The technical solution to be introduced below is generated in this context. Utility Model Content

[0005] The objective of this invention is to provide an armored joint device that significantly improves load transfer capacity to cope with vertical and impact loads generated when vehicles pass by, prevents edge chipping and cracking of concrete, facilitates ideal anchoring to ensure long-term stability and non-deformation, meets the requirements of excellent flatness, seamlessness, and true invisibility to facilitate unimpeded passage for vehicles ranging from handcarts to heavy forklifts, eliminates the need for grooves or protrusions to avoid dust accumulation and facilitates cleaning, and meets the application requirements of flooring in environments with stringent cleanliness requirements, such as food, pharmaceutical, and electronics factories.

[0006] The present invention accomplishes its objective as follows: an armor seam device comprising a left compartment seam mechanism and a right compartment seam mechanism connected to each other, characterized in that: the left compartment seam mechanism comprises a left side plate and a left anchor plate, the right side of the left anchor plate abutting against the upper left side of the left side plate; the right compartment seam mechanism comprises a right side plate and a right anchor plate, the left side of the right anchor plate abutting against the upper right side of the right side plate; and the left anchor plate, the left side plate, the right side plate, and the right anchor plate are connected by a fragile fastener that passes sequentially through the left anchor plate, the upper part of the left side plate, the upper part of the right side plate, and the upper part of the right anchor plate.

[0007] In a specific embodiment of this utility model, the opposite sides of the left side plate and the right side plate in the height direction are abutting each other; a left side plate anchor foot is folded to the left at the bottom of the left side plate in the height direction, and a right side plate anchor foot is folded to the right at the bottom of the right side plate in the height direction.

[0008] In another specific embodiment of this utility model, the left side plate anchor foot and the right side plate anchor foot are horizontal, and the left side plate anchor foot makes the left side plate form a ┘-shaped structure, while the right side plate anchor foot makes the right side plate form a └-shaped structure.

[0009] In another specific embodiment of this utility model, a left corner protection horizontal fold is folded to the left at the upper part of the left anchor plate, and a left anchor wing plate extends downward from the left anchor plate in a left-leaning state, with a left anchor cavity formed through the left anchor wing plate; a right corner protection horizontal fold is folded to the right at the upper part of the right anchor plate, and a right anchor wing plate extends downward from the right anchor plate in a right-leaning state, with a right anchor cavity formed through the right anchor wing plate.

[0010] In another specific embodiment of this utility model, the widths of the left corner protection horizontal fold and the right corner protection horizontal fold are equal and they are located on the same horizontal plane. The upper ends of the left side plate and the right side plate protrude from the upper surfaces of the left and right corner protection horizontal folds, respectively, and the degree of protrusion is the same.

[0011] In another specific embodiment of this utility model, the left anchoring wing plate and the right anchoring wing plate are symmetrical to each other.

[0012] In a further specific embodiment of this utility model, the left side plate, the left anchor plate, the right side plate, and the right anchor plate are steel plates.

[0013] In a further specific embodiment of this utility model, the steel plate is a galvanized stainless steel plate.

[0014] In yet another specific embodiment of this utility model, the easily breakable fastener is a bolt.

[0015] In yet another specific embodiment of this utility model, the bolt is a plastic bolt.

[0016] The technical advantages of this utility model are as follows: Because the left compartment joint mechanism is formed by the left side plate and the left anchor plate abutting the upper left side of the left side plate, and the right compartment joint mechanism is formed by the right side plate and the right anchor plate abutting the upper right side of the right side plate, a distributed load path can be formed with a four-piece thick, flexural and shear-resistant structure connected by easily breakable fasteners. This diffuses vertical loads and impact forces to the concrete on both sides, preventing edge chipping and cracking of the joint concrete. Furthermore, because the left anchor cavity formed on the left anchor plate and the right anchor cavity formed on the right anchor plate form a natural and strong pin-key effect with the poured concrete, under repeated impacts from vehicle loads, especially under the action of vertical force and horizontal shear force, the structure can effectively withstand these forces. It can prevent vertical detachment and floating or horizontal slippage between the concrete and the concrete. The concrete at the edges of the left and right anchoring cavities interlocks with the left and right anchoring flanges, allowing the load and stress to be smoothly transferred between the concrete and the left and right anchoring flanges. This is very beneficial for reducing local stress concentration, achieving an ideal anchoring effect, and ensuring long-term stability and no deformation. Since there are no grooves or protrusions after being poured into the concrete, it not only provides excellent aesthetics, but also meets the requirements of barrier-free passage for various vehicles with its completely flat and seamless invisible characteristics. It also avoids dust accumulation and is easy to clean, making it suitable for floors in places with strict cleanliness requirements, such as food, pharmaceutical, and electronics factories.

Detailed Implementation

[0019] In order to better understand the technical essence and beneficial effects of this utility model, a detailed description will be given below by way of embodiments. However, the description of the embodiments is not intended to limit the solution of this utility model. Any formal but not substantive equivalent transformations made based on the concept of this utility model should be considered within the scope of the technical solution of this utility model.

[0020] In the following description, all directional or positional concepts involving up, down, left, right, front, and back are based on the current position. Figure 1 The location and state of the object are taken as examples, and therefore should not be construed as a special limitation on the technical solution provided by this utility model.

[0021] Please see Figure 1 and Figure 2 The diagram shows a left compartmental joint mechanism 1 and a right compartmental joint mechanism 2 connected to each other. The left compartmental joint mechanism 1 includes a left side plate 11 and a left anchor plate 12. The right side of the left anchor plate 12 is close to the upper left side of the left side plate 11. The right compartmental joint mechanism 2 includes a right side plate 21 and a right anchor plate 22. The left side of the right anchor plate 22 is close to the upper right side of the right side plate 21. The left anchor plate 12, the left side plate 11, the right side plate 21 and the right anchor plate 22 are connected by a fragile fastener 3 passing through the upper parts of the left anchor plate 12, the left side plate 11, the right side plate 21 and the right anchor plate 22 in sequence.

[0022] As a preferred embodiment, the left anchor plate 12 is fixed to the left side plate 11 at its upper and lower parts on the side facing the left side plate 11 and along the length of the left anchor plate 12 by spaced spot welding; similarly, the right anchor plate 22 is fixed to the right side plate 21 at its upper and lower parts on the side facing the right side plate 21 and along the length of the right anchor plate 22 by spaced spot welding. The aforementioned upper and lower parts can also be referred to as the upper edge and lower edge.

[0023] Depend on Figure 1 As illustrated, easily breakable fastener through holes are provided on the upper parts of the left anchor plate 12, the left side plate 11, the right side plate 21, and the right anchor plate 22, respectively, at their corresponding positions to the easily breakable fasteners 3, i.e., in a coaxial position. After the easily breakable fasteners 3 pass through from left to right and extend to the right side of the right anchor plate 22, they are tightened with nuts 31. A distributed load transfer path is formed by connecting the four thick, four-piece structure with easily breakable fasteners 3, distributing the vertical load and impact force to the concrete 4 on both sides. Figure 3 (See illustration). The aforementioned four-piece thick structure can withstand heavier dynamic loads (such as heavy forklifts, trucks, etc.), and is safer, making it suitable for flooring in logistics warehouses, heavy industry, etc.

[0024] Depend on Figure 1 As shown, the aforementioned left side plate 11 and the aforementioned right side plate 21 are abutting each other on opposite sides in the height direction; a left side plate anchor foot 111 is folded to the left at the bottom of the left side plate 11 in the height direction, and a right side plate anchor foot 211 is folded to the right at the bottom of the right side plate 21 in the height direction. The left and right side plate anchor feet 111 and 211 form a box-shaped structure similar to a composite beam, which significantly improves the overall stiffness, reduces the dependence on the quality of concrete pouring, and enhances the resistance to torsion, shear, and bending.

[0025] The aforementioned left side plate anchor foot 111 and right side plate anchor foot 211 are horizontal, and the left side plate anchor foot 111 makes the aforementioned left side plate 11 form a ┘-shaped structure, while the right side plate anchor foot 211 makes the aforementioned right side plate form a └-shaped structure.

[0026] A left corner protection horizontal fold 121 extends to the left from the upper part of the aforementioned left anchor plate 12. A left anchoring wing plate 1211 extends downward from the left anchor plate 12 in a left-leaning tilted manner. A left anchoring cavity 12111 is formed through the left anchoring wing plate 1211. Similarly, a right corner protection horizontal fold 221 extends to the right from the upper part of the aforementioned right anchor plate 22. A right anchoring wing plate 2211 extends downward from the right anchor plate 22 in a right-leaning tilted manner. A right anchoring cavity 22111 is formed through the right anchoring wing plate 2211. This structural design objectively reflects the corresponding technical effects described by the applicant in the above-mentioned technical effects section.

[0027] In this embodiment, and by Figure 1 As shown, the widths of the aforementioned left corner protection horizontal fold 121 and the aforementioned right corner protection horizontal fold 221 are equal and located on the same horizontal plane. The upper ends of the aforementioned left side plate 11 and right side plate 21 protrude from the upper surfaces of the left and right corner protection horizontal folds 121 and 221, respectively, and the degree of protrusion is the same. The distance from the top of the protruding part to the left and right corner protection horizontal folds 121 and 221 is compensated by the aforementioned concrete 4. Figure 3 (As shown), there are no protrusions or grooves, thus fulfilling the corresponding technical effects described by the applicant in the technical effects section above.

[0028] Depend on Figure 1 As can be seen from the diagram, the aforementioned left anchoring wing plate 1211 and the aforementioned right anchoring wing plate 2211 are symmetrical to each other.

[0029] In this embodiment, the aforementioned left side plate 11, left anchor plate 12, right side plate 21 and right anchor plate 22 are steel plates, specifically galvanized stainless steel plates, and hot-dip galvanized stainless steel plates.

[0030] In this embodiment, the aforementioned easily breakable fastener 3 is a bolt, specifically a plastic bolt. Once the bolt breaks, a metal edge shrinkage joint is formed.

[0031] Please see Figure 3 At the pouring site, a waterproof membrane 51 is first laid on the upper surface of the base layer 5. The material of the base layer 5 is usually a mixture of cement fragments, lime, fly ash, and crushed stone. Reinforced concrete, namely the aforementioned concrete 4, is formed on top of the waterproof membrane 51. Before pouring the concrete 4, the armor seam device of this utility model is incorporated into the reinforcing steel according to the construction process requirements. After pouring, it forms... Figure 3 The state shown.

[0032] In summary, the technical solution provided by this utility model makes up for the shortcomings of the prior art, successfully completes the invention task, and faithfully realizes the technical effects described by the applicant in the above technical effect column.
