Description

Technical Field

[0001] This utility model belongs to the field of prefabricated buildings, and in particular relates to a connector, a wall panel connection structure, and a novel wall. Background Technology

[0002] In the field of prefabricated buildings, wall installation technology has always been a key factor affecting building quality and construction efficiency. Traditional installation methods are mainly divided into two categories: "wet connection" and "dry connection," each with its own advantages and disadvantages.

[0003] "Wet connection" is represented by rebar connection. It tightly integrates precast wall panels with the main structure through wet operations. It has good integrity and seismic performance, but it has problems such as complex construction, low efficiency and great influence from weather, making it difficult to meet the needs of rapid construction.

[0004] "Dry connection" primarily utilizes C-shaped steel keel systems, offering advantages such as high prefabrication, rapid construction, high precision, and suitability for non-load-bearing exterior walls. However, it also has some limitations. Because C-shaped steel keels and precast wall panels are made of different materials with varying coefficients of thermal expansion, their deformation differs with changes in ambient temperature. This leads to stress concentration at the C-shaped steel keel, potentially causing wall cracking. Furthermore, C-shaped steel keels are typically continuous structures, failing to effectively distribute stress. Under load or deformation, cracks easily appear, affecting the wall's integrity and durability.

[0005] Therefore, this utility model came into being.

[0006] It should be noted that the information disclosed in the background section of this utility model is intended only to enhance the understanding of the general background of this utility model, and should not be regarded as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] One objective of this utility model is to provide a high-efficiency connector for the assembly and installation of prefabricated walls; The second objective of this utility model is to propose a wall panel connection structure that is highly modular and easy to assemble. The third objective of this utility model is to propose a new type of wall that is highly assembled and not prone to cracking.

[0008] To achieve one of the above objectives, this utility model first provides a connector for assembling adjacent precast wall panels, comprising: A connecting body is located at the joint between adjacent prefabricated wall panels; Two insertion parts are located on the connecting body and are correspondingly inserted and fixed to the adjacent prefabricated wall panels; At least one limiting part is provided on the connecting body on the side close to the precast wall panel, and the limiting part forms at least one limiting surface that is flat against the adjacent precast wall panel; At least one mounting part for mounting the structural mesh, the mounting part being located on the side of the connecting body away from the precast wall panel.

[0009] Preferably, the connector is formed by cutting and bending a whole plate; the middle section of the whole plate near the precast wall panel is cut and bent to form the limiting part, and the two sides of the middle section form the two insertion parts; the side of the whole plate away from the precast wall panel is cut and bent to form the hanging part.

[0010] Preferably, the limiting portion is formed by bending the middle section as a whole upward or downward; or by bending the middle section separately upward and / or downward.

[0011] Preferably, the insertion portion is bent to form a folded edge that is inserted into the precast wall.

[0012] Preferably, the side of the whole panel away from the precast wall panel is cut and bent to form the hanging part, and the hanging part is a hanging tooth part.

[0013] The technical effect of this solution comes from one or more of the following combinations: The connector uses a plug-in part to connect two adjacent precast wall panels, and a limiting part to level the joint, forming a hanging part for the mesh on the outside. The entire structure only requires operation on one side of the precast wall panel, causes minimal damage to the precast wall panel, has a simple structure, and is easy to install.

[0014] The entire structure can be formed by cutting and bending a single piece of board, which is economical and easy to manufacture.

[0015] The outer side of the connector has a toothed part for hanging, which facilitates the installation of the structural mesh on the outside of the precast wall panel.

[0016] To achieve the above two objectives, this utility model also provides a wall panel connection structure, which includes at least two prefabricated wall panels. The joints of adjacent prefabricated wall panels are connected by the aforementioned connectors, and the two insertion parts of the connectors are correspondingly inserted and fixed to the adjacent prefabricated wall panels.

[0017] The technical effect of this solution comes from one or more of the following combinations: In the wall panel connection structure, the connectors use interlocking parts to connect two adjacent precast wall panels, and the limiting parts level the joints, forming a hanging part for the mesh on the outside. The entire structure only requires operation on one side of the precast wall panel, causes minimal damage to the precast wall panel, is simple in structure, and is easy to install.

[0018] Multiple prefabricated wall panels, whether arranged side-by-side or stacked, can be easily connected using connectors, which can also improve the shear resistance at the joints.

[0019] To achieve the above three objectives, this utility model also provides a novel wall, which includes at least a structural mesh, an outer cladding layer, and the aforementioned wall panel connection structure; the wall panel connection structure is installed on the main structure between floors, the structural mesh is laid on the connectors on both sides of the precast wall panel, and the outer cladding layer is formed on the structural mesh.

[0020] Preferably, the precast wall panel is positioned on the main structure by a positioning member, the positioning member being fixed to the main structure and having a clamping section for clamping the precast wall panel.

[0021] Preferably, the clamping section is provided with a first slot, and the structural mesh is installed and fixed in the first slot and / or the hanging part.

[0022] Preferably, the clamping section is provided with a first through hole for the through connection of the outer coating layer.

[0023] The technical effects achieved by the above-mentioned technical solution of this utility model are derived from one or more of the following combinations: Compared to the traditional C-shaped steel keel installation method, this solution uses positioning components to position the prefabricated wall panels, which are then fixed together with connectors. It also provides an installation carrier for the structural mesh. Its integrated, fully prefabricated installation saves material and labor costs. The connectors improve the shear resistance at the joints, and in actual operation, it has been found to be less prone to cracking compared to the C-shaped steel keel installation method.

[0024] Compared to traditional rebar installation methods, this solution is faster, more convenient, and more cost-effective.

[0025] The through holes on the positioning components allow the outer mortar layer to form an interlocking structure. The structural mesh is fixed by the slots and hanging teeth, preventing hollow areas from falling off and ensuring a smoother installation.

[0026] The fully prefabricated construction method involves 100% dry work, eliminating grouting / cast-in-place processes and shortening the construction period. Furthermore, the bending design of the positioning components improves the efficiency of wall panel installation and saves costs.

[0027] The clamping section's cross-joint design can coordinate the deformation of adjacent wall panels, thereby enhancing the overall structural integrity.

[0028] The connectors improve the shear strength of the joints between precast wall panels.

[0029] Compared to traditional C-shaped steel keel, this solution uses positioning components for positioning and fixing, followed by bending and clamping, thus altering the stress transmission path and distribution. The clamping section of the positioning component spans the joint between adjacent precast wall panels. This joint-spanning design allows stress to be more evenly distributed across adjacent wall panels and the positioning component, preventing stress concentration at the joint. When the wall is subjected to external forces or environmental changes causing deformation, the joint-spanning clamping section can coordinate the deformation of adjacent wall panels, reducing concentrated stress caused by deformation differences, thereby lowering the risk of cracking.

[0030] The structural mesh is laid on both sides of the precast wall panel and fixed to the positioning and connecting parts through slots and hanging teeth, tightly bonding with the outer cladding layer. The structural mesh forms a three-dimensional spatial network structure, effectively enhancing the integrity and crack resistance of the outer cladding layer. Under external force or deformation, the structural mesh can disperse stress, limit the deformation of the outer cladding layer, and prevent cracking due to excessive stress. Simultaneously, the through-hole design allows the outer cladding mortar to form an interlocking structure, further enhancing the integrity and crack resistance of the outer cladding layer.

[0031] This solution enables fully prefabricated construction. The installation of positioning components and the embedding of precast wall panels can both be prefabricated in the factory, requiring only simple installation and assembly on-site, significantly shortening the construction cycle. Furthermore, the bending design of the positioning components makes wall panel installation more convenient and efficient, saving labor and time costs.

[0032] In summary, this new type of wall and its installation method not only solve the problem of easy cracking in traditional installation methods, but also have many advantages such as high construction efficiency, low cost, and good integrity. It can better meet the development needs of prefabricated buildings and is of great significance to promoting the progress of prefabricated building technology. Attached Figure Description

[0052] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. It should be noted that the aspects described below with reference to the accompanying drawings and specific embodiments are merely exemplary and should not be construed as limiting the scope of protection of the present invention in any way.

[0053] Example 1: Please see Figure 1 and Figure 2 This embodiment provides a connector for assembling adjacent precast wall panels 2. Its structure includes a connecting body 11, insertion parts 12, limiting parts 13, and hanging parts 14. The connecting body 11 is located at the joint 20 of adjacent precast wall panels 2; two insertion parts 12 are located on the connecting body 11 and correspondingly inserted and fixed to the adjacent precast wall panels 2; the limiting part 13 is located on the connecting body 11 on the side closest to the precast wall panel 2, and the limiting part 13 forms at least one limiting surface that is flush with the adjacent precast wall panel 2; the hanging part 14 is used to hang the structural mesh 5 on the side of the panel, and this hanging part 14 is located on the connecting body 11 on the side away from the precast wall panel 2.

[0054] The connector 1 can be formed by combining the above-mentioned parts, or it can be formed by integrally molding multiple parts. This embodiment does not limit the structural form of the insertion part 12, the limiting part 13, and the hanging part 14. This embodiment describes the preferred implementation as a plate form in detail.

[0055] For specific details, please refer to... Figure 1 and Figure 2 The connector 1 is formed by cutting and bending a whole plate. Specifically, the middle section of the whole plate near the precast wall panel 2 is cut and bent to form a limiting part 13, with insertion parts 12 formed on both sides of the middle section. The side of the whole plate away from the precast wall panel 2 is cut and bent to form a hanging part 14. Taking a steel plate as an example, the steel plate is placed horizontally, and the side near the precast wall panel 2 is divided into three sections: short-long-short. The middle long section is bent to form the limiting part 13, and the limiting surface is formed on the surface of the limiting part 13 facing the precast wall panel 2.

[0056] Furthermore, the limiting portion 13 is formed by bending the middle section upwards or downwards as a whole. Alternatively, it can be formed by bending the middle section separately upwards and / or downwards. Preferably, to increase stability, the middle section (long section) is further divided into three segments, with the middle end bent upwards and the two outer segments bent downwards, forming a stable T-shaped structure with the connecting body 11. More preferably, the bending angle of the limiting portion 13 is 90°.

[0057] It should be noted that this embodiment does not limit the specific dimensional parameters of the above-mentioned parts. They can be adjusted according to actual needs, and the dimensional ratios between them do not necessarily form a specific relationship.

[0058] Furthermore, to increase the rigidity of the insertion part 12 and prevent deformation of the inserted precast wall panel 2, the insertion part 12 is bent to form a folded edge 121 that is inserted into the precast wall. This makes the entire insertion part 12 form an angle steel shape.

[0059] In a preferred embodiment of this invention, the hanging part 14 is designed to hang out of the wall, serving as the mounting point for the structural mesh 5. Specifically, the hanging part 14 is formed by cutting and bending on the side of the whole panel away from the precast wall panel 2, and the hanging part 14 is implemented as a toothed hanging part. The toothed structure of the hanging part 14 can better hang the structural mesh 5, forming multiple hanging points, making the structural mesh 5 more stably installed.

[0060] It should be noted that the connector 1 in this embodiment can be formed by cutting and bending a steel plate, or by welding multiple steel plates together, or by stamping a single piece of plate. Alternatively, it can be formed by compression molding of high-strength composite materials, etc.

[0061] Example 2: Please see Figure 3 and Figure 4and combined Figure 1 and Figure 2 This embodiment provides a wall panel connection structure, which includes at least two prefabricated wall panels 2. The joints 20 of adjacent prefabricated wall panels 2 are connected by a connector 1 of embodiment 1. The two plug-in parts 12 of the connector 1 are correspondingly inserted and fixed to the adjacent prefabricated wall panels 2.

[0062] In this embodiment, the precast wall panel 2 can be a concrete slab, a lightweight concrete slab, or a sandwich concrete slab. The sandwich concrete slab includes two leaf panels and an insulation board, with the insulation board positioned between the two leaf panels. The two leaf panels are connected by tie rods, which is prior art and will not be described in detail. Alternatively, as a preferred embodiment, the precast wall panel 2 can be a lightweight thermal insulation and soundproofing board, such as thermosetting board, XPS board, or EPS board.

[0063] Please see Figure 1 and Figure 2 The connector 1 includes a connecting body 11, a plug-in part 12, a limiting part 13, and a hanging part 14. The connecting body 11 is located at the joint 20 of adjacent precast wall panels 2; two plug-in parts 12 are located on the connecting body 11 and are correspondingly inserted and fixed to the adjacent precast wall panels 2; the limiting part 13 is located on the connecting body 11 on the side closest to the precast wall panel 2, and the limiting part 13 forms at least one limiting surface that is flush with the adjacent precast wall panel 2; the hanging part 14 is used to hang the structural mesh 5 on the side of the panel, and this hanging part 14 is located on the connecting body 11 on the side away from the precast wall panel 2.

[0064] The connector 1 can be formed by combining the above-mentioned parts, or it can be formed by integrally molding multiple parts. This embodiment does not limit the structural form of the insertion part 12, the limiting part 13, and the hanging part 14. This embodiment describes the preferred implementation as a plate form in detail.

[0065] Specifically, connector 1 is formed by cutting and bending a whole plate. Specifically, the middle section of the whole plate near the precast wall panel 2 is cut and bent to form a limiting part 13, with insertion parts 12 formed on both sides of the middle section. The side of the whole plate away from the precast wall panel 2 is cut and bent to form a hanging part 14. Taking a steel plate as an example, the steel plate is placed horizontally, and the side near the precast wall panel 2 is divided into three sections: short-long-short. The middle long section is bent to form the limiting part 13, and the limiting surface is formed on the surface of the limiting part 13 facing the precast wall panel 2.

[0066] Furthermore, the limiting portion 13 is formed by bending the middle section upwards or downwards as a whole. Alternatively, it can be formed by bending the middle section separately upwards and / or downwards. Preferably, to increase stability, the middle section (long section) is further divided into three segments, with the middle end bent upwards and the two outer segments bent downwards, forming a stable T-shaped structure with the connecting body 11. More preferably, the bending angle of the limiting portion 13 is 90°.

[0067] It should be noted that this embodiment does not limit the specific dimensional parameters of the above-mentioned parts. They can be adjusted according to actual needs, and the dimensional ratios between them do not necessarily form a specific relationship.

[0068] Furthermore, to increase the rigidity of the insertion part 12 and prevent deformation of the inserted precast wall panel 2, the insertion part 12 is bent to form a folded edge 121 that is inserted into the precast wall. This makes the entire insertion part 12 form an angle steel shape.

[0069] In a preferred embodiment of this invention, the hanging part 14 is designed to hang out of the wall, serving as the mounting point for the structural mesh 5. Specifically, the hanging part 14 is formed by cutting and bending on the side of the whole panel away from the precast wall panel 2, and the hanging part 14 is implemented as a toothed hanging part. The toothed structure of the hanging part 14 can better hang the structural mesh 5, forming multiple hanging points, making the structural mesh 5 more stably installed.

[0070] It should be noted that the connector 1 in this embodiment can be formed by cutting and bending a steel plate, or by welding multiple steel plates together, or by stamping a single piece of plate. Alternatively, it can be formed by compression molding of high-strength composite materials, etc.

[0071] Example 3: Please see Figures 5-11 and combined Figures 1-4 This embodiment provides a novel wall structure, including positioning elements 3, wall panel connection structures, structural mesh 5, and an outer cladding layer 6. Multiple positioning elements 3 are installed on the main structure 4 between floors, arranged side-by-side with spacing. Each positioning element 3 includes at least an mounting part 31 and a clamping section 32, with the clamping section 32 capable of bending relative to the mounting part 31. The wall panel connection structures are installed between the main structures 4 of the floors. At least one positioning element 3 is provided on each side of the precast wall panel 2, and the positioning element 3 is bent and clamped relative to the clamping section 32 for positioning. The structural mesh 5 is laid on both sides of the precast wall panel 2. The outer cladding layer 6 is formed on the structural mesh 5. Compared to the traditional C-shaped steel keel installation structure, the gap between the C-shaped steel keel and the precast wall panel 2 is prone to cracking due to material differences in practice. In this solution, the positioning elements 3 are used for positioning and fixing, then bent and clamped, and then the outer cladding layer 6 is formed in conjunction with the structural mesh 5. The overall structure is not continuous, thus preventing cracks. Furthermore, compared to traditional rebar installation methods, this solution offers higher assemblability and is easier to install.

[0072] The above technical solutions constitute the necessity for the implementation of this embodiment, and will be described in detail below with reference to the accompanying drawings: Please combine Figure 5 and Figure 6The positioning component 3 is mainly used to position and install the precast wall panels 2 between the main structures 4 of the floor. In this embodiment, the main structure 4 can be beams and floor slabs. Taking the top and bottom main structures 4 of a certain floor as an example, the top main structure 4 can be a secondary beam, and the bottom main structure 4 can be a floor slab. In this embodiment, for ease of explanation, the illustration of the floor slab is omitted.

[0073] Based on the function of the positioning element 3, in the preferred embodiment of this first embodiment, please refer to... Figure 5 and Figure 6 and combined Figure 7 and Figure 8 The positioning element 3 is a positioning piece. One end of the positioning piece is defined as the mounting part 31, used for fixed installation with the main structure 4, and the other end is defined as the clamping section 32, used for clamping and positioning the precast wall panel 2. The clamping section 32 is provided with a first slot 321, and the structural mesh 5 is installed and fixed in the first slot 321. Furthermore, the positioning piece is an iron sheet, steel sheet, or other metal sheet of a certain thickness. This embodiment does not arbitrarily limit its thickness; it only needs to meet the requirement of having lateral stiffness to clamp the precast wall panel 2 and being able to be bent by a tool, for example, 5mm.

[0074] In a preferred embodiment of this invention, the positioning pieces are installed and fixed on the top and bottom main structures 4 in a flat state to facilitate the embedding of the precast wall panel 2. Of course, a flat state is not necessarily the only option in this embodiment; the purpose is simply to allow the precast wall panel 2 to be embedded from the side. After embedding, the clamping sections 32 on the positioning pieces on both sides of the precast wall panel 2 are formed into clamping ribs for holding the precast wall panel 2 by manual or mechanical bending.

[0075] It should be noted that the positioning element 3 can also be implemented as a flat tube, flat rod, or other structure, which will not be described in detail here.

[0076] Specifically, the positioning component 3 is fixed to the main structure 4 using self-tapping screws, chemical bolts, or expansion bolts. Furthermore, such as... Figure 6 As shown, the positioning components 3 are arranged in pairs, divided into upper and lower columns. The upper column is spaced apart on the top main structure 4 (such as secondary beams), and the lower column is spaced apart on the bottom main structure 4 (such as floor slabs).

[0077] When the clamping section 32 of the positioning member 3 is bent to form a clamping rib, it also serves as a structural component of the outer covering layer 6. In addition to the first slot 321 provided in the clamping section 32, a first through hole 322 can also be provided on the clamping section 32. This first through hole 322 is used for the through connection of the outer covering layer 6, allowing the outer covering layers 6 on both sides of the clamping section 32 to be connected and connected, preventing cracking, improving the bolting effect between the outer covering layer 6 and the clamping section 32, and ensuring that the clamping section 32 does not cut off the outer covering layer 6 due to its own width.

[0078] For details, please refer to Figure 8 The first slot 321 is preferably a C-shaped slot, which is continuously designed outward along the length of the clamping section 32. The size of its slot opening is designed to allow the wires of the structural mesh 5 to pass through, and the C-shaped slot itself can also better form the connection function of the outer covering layer 6. The first through hole 322 can be a circular hole or an elongated hole. Similarly, like the C-shaped slot, the first through hole 322 is also designed to be continuously designed along the length of the clamping section 32.

[0079] In this embodiment, the precast wall panel 2 can be a concrete slab, a lightweight concrete slab, or a sandwich concrete slab. The sandwich concrete slab includes two leaf panels and an insulation board, with the insulation board positioned between the two leaf panels. The two leaf panels are connected by tie rods, which is prior art and will not be described in detail. Alternatively, as a preferred embodiment, the precast wall panel 2 can be a lightweight thermal insulation and soundproofing board, such as thermosetting board, XPS board, or EPS board.

[0080] To facilitate the installation of prefabricated wall panels, in this embodiment, the number of prefabricated wall panels 2 is at least two. Multiple prefabricated wall panels 2 are assembled according to the wall width requirements, and then uniformly smoothed and integrated by the outer covering layer 6 to form a unified structure. Figure 11 The effect shown is as follows. To improve overall integrity, adjacent precast wall panels 2 are connected by connectors 1. Furthermore, adjacent precast wall panels 2 are connected to each other by connectors 1.

[0081] Please see Figure 1 and Figure 2 The connector 1 includes a connecting body 11, a plug-in part 12, a limiting part 13, and a hanging part 14. The connecting body 11 is located at the joint 20 of adjacent precast wall panels 2; two plug-in parts 12 are located on the connecting body 11 and are correspondingly inserted and fixed to the adjacent precast wall panels 2; the limiting part 13 is located on the connecting body 11 on the side closest to the precast wall panel 2, and the limiting part 13 forms at least one limiting surface that is flush with the adjacent precast wall panel 2; the hanging part 14 is used to hang the structural mesh 5 on the side of the panel, and this hanging part 14 is located on the connecting body 11 on the side away from the precast wall panel 2.

[0082] The connector 1 can be formed by combining the above-mentioned parts, or it can be formed by integrally molding multiple parts. This embodiment does not limit the structural form of the insertion part 12, the limiting part 13, and the hanging part 14. This embodiment describes the preferred implementation as a plate form in detail.

[0083] Specifically, connector 1 is formed by cutting and bending a whole plate. Specifically, the middle section of the whole plate near the precast wall panel 2 is cut and bent to form a limiting part 13, with insertion parts 12 formed on both sides of the middle section. The side of the whole plate away from the precast wall panel 2 is cut and bent to form a hanging part 14. Taking a steel plate as an example, the steel plate is placed horizontally, and the side near the precast wall panel 2 is divided into three sections: short-long-short. The middle long section is bent to form the limiting part 13, and the limiting surface is formed on the surface of the limiting part 13 facing the precast wall panel 2.

[0084] Furthermore, the limiting portion 13 is formed by bending the middle section upwards or downwards as a whole. Alternatively, it can be formed by bending the middle section separately upwards and / or downwards. Preferably, to increase stability, the middle section (long section) is further divided into three segments, with the middle end bent upwards and the two outer segments bent downwards, forming a stable T-shaped structure with the connecting body 11. More preferably, the bending angle of the limiting portion 13 is 90°.

[0085] It should be noted that this embodiment does not limit the specific dimensional parameters of the above-mentioned parts. They can be adjusted according to actual needs, and the dimensional ratios between them do not necessarily form a specific relationship.

[0086] Furthermore, to increase the rigidity of the insertion part 12 and prevent deformation of the inserted precast wall panel 2, the insertion part 12 is bent to form a folded edge 121 that is inserted into the precast wall. This makes the entire insertion part 12 form an angle steel shape.

[0087] In a preferred embodiment of this invention, the hanging part 14 is designed to hang out of the wall, serving as the mounting point for the structural mesh 5. Specifically, the hanging part 14 is formed by cutting and bending on the side of the whole panel away from the precast wall panel 2, and the hanging part 14 is implemented as a toothed hanging part. The toothed structure of the hanging part 14 can better hang the structural mesh 5, forming multiple hanging points, making the structural mesh 5 more stably installed.

[0088] It should be noted that the connector 1 in this embodiment can be formed by cutting and bending a steel plate, or by welding multiple steel plates together, or by stamping a single piece of plate. Alternatively, it can be formed by compression molding of high-strength composite materials, etc.

[0089] It should be noted that the structural mesh 5 can be installed and fixed to the first slot 321 and / or the hanging part 14. For the preferred embodiment, please refer to... Figure 9 and Figure 10 The structural mesh 5 is installed and fixed to the hanging part 14 and the first slot 321 to form a uniform laying and fixing.

[0090] It is worth mentioning that, please combine Figure 9When the clamping section 32 is bent and clamped onto the precast wall panel 2, its position spans the joint 20 of the adjacent precast wall panels 2. This allows for the alignment of adjacent precast walls, pre-positioning them before the U-shaped pins are used for positioning. Furthermore, this joint-spanning design allows stress to be distributed more evenly across the adjacent wall panels and positioning components 3, preventing stress concentration at the joint 20. When the wall is subjected to external forces or environmental changes and deforms, the clamping section 32 can coordinate the deformation of adjacent wall panels, reducing concentrated stress caused by deformation differences, thereby reducing the risk of cracking.

[0091] Furthermore, the present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
