Description

Technical Field

[0001] This utility model relates to the field of reinforced concrete technology, specifically to a protective angle steel. Background Technology

[0002] To ensure the stability and safety of reinforced concrete structures and prevent damage to the edges and corners from collisions and friction, which could lead to chipping or spalling, edge protection angle steel is an important auxiliary component widely used to protect structural edges, enhance structural connection strength, and prevent displacement of the angle steel during concrete pouring. Edge protection angle steel effectively prevents cracking and spalling of concrete edges, while providing additional support and protection for the reinforced concrete structure, ensuring its integrity and durability.

[0003] Currently, common edge-protecting angle steel on the market typically consists of angle steel and multiple bent anchors, with the anchors spaced at intervals on the inner corners of the angle steel. However, due to limitations in the spacing of the anchors and the welding process, the heat generated during welding can lead to uneven heating of the angle steel, resulting in uneven welding deformation. This uneven welding deformation not only affects the appearance quality of the angle steel but, more importantly, reduces its stiffness and the overall structural stability. The concrete edge-protecting angle steel structure disclosed in publication number CN222557881U achieves more uniform welding deformation by increasing the spacing between adjacent anchor bars, ensuring that the surface curvature and the straightness deviation of the leading edge meet the requirements.

[0004] However, the above solution still involves welding the bent anchors to the angle steel at intervals. Although this can alleviate the uneven welding deformation of the angle steel to some extent, it cannot completely solve the problem. Utility Model Content

[0005] The present invention aims to provide a protective angle steel that eliminates uneven welding deformation on the surface of the angle steel and improves the rigidity of the protective angle steel.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An edge-protecting angle steel includes an angle steel body, the angle steel body having a first side and a second side perpendicular to each other, a positioning member and a reinforcing member provided on the inner side of the angle steel body, the positioning member including a connecting plate and a positioning block, the positioning block being connected to the right-angle corner of the inner side of the angle steel body, one side of the connecting plate being fixedly connected to the positioning block, the other side of the connecting plate being fixedly connected to the reinforcing member, the two ends of the reinforcing member being fixedly connected to the first side and the second side respectively, and the reinforcing member being provided with a plurality of first bent anchors and a plurality of second bent anchors.

[0008] The principle and advantages of this scheme are:

[0009] 1. A reinforcing member was added. The reinforcing member is placed between the first and second sides of the angle steel body, and the two ends of the reinforcing member are welded to the first and second sides to form an isosceles right triangle support frame. This transforms the force on the two vertical sides of the angle steel body into a triangular truss structure, which can improve the bending and torsional stiffness of the angle steel body. It can also distribute the load on the first and second sides of the angle steel body and avoid stress concentration at the connection between the first and second sides.

[0010] 2. The positioning block is set at the right-angle corner inside the angle steel body and fits against the first and second sides. First, it can enhance the stability of the connection between the first and second sides and bear part of the load. Second, the positioning block also provides a precise positioning reference for the installation of the reinforcement. After the positioning block is placed, the reinforcement will naturally be in the accurate installation position and can be welded directly without adjusting the installation position of the reinforcement.

[0011] 3. The first and second curved anchors are first connected to the reinforcing member, and then connected to the angle steel body through the reinforcing member. The reinforcing member and the angle steel body are fully welded along a straight line, and the weld is evenly distributed on the angle steel body. This avoids the uneven welding deformation caused by directly welding the first and second curved anchors to the angle steel body at intervals.

[0012] 4. All welding methods mentioned in this plan are full welding, which can significantly avoid uneven welding deformation.

[0013] Preferably, as an improvement, the positioning block is a triangular pyramid structure, the cross section of the positioning block is a right triangle, and the two right-angled sides of the positioning block are respectively attached to the first side and the second side of the angle steel body.

[0014] Technical benefits: The above-mentioned setup allows the positioning block's special structure to directly engage with the right-angle corner of the angle steel body, eliminating the need for manual positioning and calibration, thus ensuring installation accuracy. Furthermore, the positioning block simultaneously contacts both the first and second sides, constraining the risk of displacement between the first and second sides and improving the rigidity of the angle steel body.

[0015] Preferably, as an improvement, the reinforcing member includes a support plate and a fixing plate integrally formed on both sides of the support plate, and the two fixing plates are respectively fixedly connected to the first side and the second side of the angle steel body.

[0016] Technical effect: The above-mentioned setup is used in this solution. The two fixing plates are welded to the first and second sides of the angle steel body in a straight line and are fully welded. This can distribute the load of the angle steel body and suppress uneven welding deformation.

[0017] Preferably, as an improvement, the included angle between the support plate and the fixing plate is 135°.

[0018] Technical effect: The above-mentioned arrangement in this solution makes the angle between the support plate and the first and second sides of the angle steel body both 45°, forming an isosceles right-angled triangular truss structure, which can significantly improve the compressive and tensile strength of the angle steel body, and can also share the load on the first and second sides of the angle steel body.

[0019] Preferably, as an improvement, one end of the plurality of first curved anchors is fixedly disposed at the connection between the support plate and a side fixing plate, and one end of the plurality of second curved anchors is fixedly disposed at the connection between the support plate and the other side fixing plate, and the first curved anchors and second curved anchors are arranged alternately.

[0020] Technical effect: The above-mentioned arrangement of the first and second curved anchors can avoid stress concentration on the angle steel after the curved anchor is pulled by external force, compared with the straight-line installation of the curved anchor. The staggered arrangement of the first and second curved anchors can disperse the external force to both sides of the angle steel body, avoiding excessive stress in the middle that may cause cracking.

[0021] Preferably, as an improvement, the ends of the first and second curved anchors that are away from the support plate are inclined to opposite sides.

[0022] Technical effect: The above-mentioned setting is adopted in this solution. This inclined design makes the projection of the bent anchor in the direction perpendicular to the length of the angle steel body intersect. The intersecting bent anchor can better disperse and bear external forces in different directions, so that the edge protection angle steel can still maintain stable performance under complex stress conditions.

[0023] Preferably, as an improvement, the ends of the first and second curved anchors away from the support plate are provided with hooks, and the hooks of the first and second curved anchors are arranged opposite to each other.

[0024] Technical effect: With the above-mentioned configuration, the two oppositely positioned hooks can provide two opposing reaction forces when subjected to force, forming a mechanical interlock, which can better resist the pulling force of external forces and prevent the anchor from coming off the connection.

[0025] Preferably, as an improvement, a flat steel is fixedly provided on the outer side of the angle steel body, and the flat steel is located on the first edge of the angle steel body.

[0026] Technical effect: This solution adopts the above setting, placing the flat steel on the side of the angle steel body that will be subjected to external force. When the angle steel body is subjected to external force and has a tendency to rotate, the flat steel can counteract this tendency and improve the stability during use. Attached Figure Description

[0032] The following detailed description illustrates the specific implementation method:

[0033] Example

[0034] The basics are as follows: Figure 1-4 As shown:

[0035] An angle steel guard includes an angle steel body 1, which includes a first side and a second side that are perpendicular to each other. In this embodiment, the side where the first side and the second side form a 90° angle is referred to as the inner side of the angle steel body 1, and the corresponding side is referred to as the outer side. The inner side of the angle steel body 1 is provided with a positioning member and a reinforcing member 3. Specifically, as shown... Figure 1 As shown, the positioning component includes a connecting plate 4 and a positioning block 5. The positioning block 5 is connected to the right-angle corner of the inner side of the angle steel body 1. The positioning block 5 has a triangular pyramid structure with a right-angled triangle cross-section. The two right-angled sides of the positioning block 5 are respectively attached to the first and second sides of the angle steel body 1. One side of the connecting plate 4 is fixedly connected to the side of the positioning block 5 with its hypotenuse, and the other side is fixedly connected to the reinforcing member 3. In this embodiment, the connecting plate 4, the positioning block 5, and the reinforcing member 3 are all fixedly connected by welding. The two ends of the reinforcing member 3 are fixedly connected to the first and second sides respectively, which is done by welding. Multiple first curved anchors 6 and multiple second curved anchors 7 are welded onto the reinforcing member 3.

[0036] The reinforcing member 3 includes a support plate 31 and a fixing plate 32 integrally formed on both sides of the support plate 31. The two fixing plates 32 are fixedly connected to the first side and the second side of the angle steel body 1, respectively, by welding. The included angle between the support plate 31 and the fixing plate 32 is 135°, so that the included angle between the support plate 31 and the first side and the second side of the angle steel body 1 is 45°, forming a stable isosceles right triangle structure.

[0037] like Figure 4As shown, one end of each of the multiple first curved anchors 6 is fixed at the connection between the support plate 31 and one side fixing plate 32, and one end of each of the multiple second curved anchors 7 is fixed at the connection between the support plate 31 and the other side fixing plate 32. The first curved anchors 6 and second curved anchors 7 are arranged alternately. The ends of the first curved anchors 6 and second curved anchors 7 away from the support plate 31 are inclined to the opposite side, as shown. Figure 1 As shown, the projections of the first bent anchor 6 and the second bent anchor 7 in the direction perpendicular to the length of the angle steel body 1 are intersecting, and the ends of the first bent anchor 6 and the second bent anchor 7 away from the support plate 31 are provided with hooks, and the hooks of the first bent anchor 6 and the second bent anchor 7 are arranged opposite to each other.

[0038] A flat steel 2 is fixedly provided on the outer side of the angle steel body 1. The flat steel 2 is located on the first edge of the angle steel body 1, and one end of the flat steel 2 extends beyond the edge of the first edge. In actual installation, the flat steel 2 is placed on the side of the angle steel body 1 that will be subjected to external force.

[0039] In the actual assembly of the edge protection angle steel, first weld one side of the fixing plate 32 to the positioning block 5, and the other side to the support plate 31. Then, weld multiple first bend anchors 6 and second bend anchors 7 sequentially to the junction of the support plate 31 and the fixing plate 32. After connecting the positioning component, the reinforcing component 3, the first bend anchor 6, and the second bend anchor 7 into a whole, place the positioning block 5 at the right angle inside the angle steel body 1, so that the sides of the two right angle sides of the positioning block 5 are respectively attached to the inner sides of the first and second sides of the angle steel body 1 for positioning. At this time, the two fixing plates 32 of the reinforcing component 3 will also be attached to the inner sides of the first and second sides of the angle steel body 1. Weld the two fixing plates 32 to the first and second sides of the angle steel body 1 respectively, and the entire edge protection angle steel assembly is completed. Finally, install it in the reinforced concrete structure according to the normal procedure.

[0040] It should be noted that the welding method used in this embodiment is full welding.
