Description

Technical Field

[0001] This utility model relates to the field of reinforced concrete structural beam technology, and in particular to a precast reinforced concrete structural beam structure. Background Technology

[0002] Precast reinforced concrete structural beams are beams made of reinforced concrete materials. Reinforced concrete beams can be made into independent beams, or they can be integrated with reinforced concrete slabs to form a beam-slab floor system, or integrated with reinforced concrete columns to form a single-story or multi-story frame. Although existing precast reinforced concrete structural beams can be used to build prefabricated houses.

[0003] An existing precast reinforced concrete structural beam structure can be found in Chinese Utility Model Patent Publication No. CN222183863U, which discloses an assembled precast reinforced concrete structural beam, including a main body of the reinforced concrete structural beam. Both sides of the main body of the reinforced concrete structural beam are provided with lifting components. Each lifting component includes slots formed on the outer walls of both sides of the main body of the reinforced concrete structural beam. The inner wall of each set of slots is provided with two sets of anti-slip slots. A baffle is provided on one side of the outer wall of each anti-slip slot. The upper and lower ends of the baffle are connected to the inner wall of the slot. A square groove is provided on one side of the baffle. In this utility model, by designing an assembled precast reinforced concrete structural beam, a locking block slides into the slot and is fixed inside the anti-slip slot. A protrusion at one end of the locking block connects to the square groove on one side of the baffle to limit the locking block's position, facilitating lifting via rings. Simultaneous lifting with four sets of rings increases the stability of lifting the main body of the reinforced concrete structural beam.

[0004] However, in actual use, it was found that the precast reinforced concrete beams were not convenient to move and hoist during transportation projects. They required laborious binding, and the binding ropes wrapped around the precast reinforced concrete beams were prone to wear during hoisting, which made it inconvenient to use the precast reinforced concrete beams. Therefore, this application provides a precast reinforced concrete beam structure to meet the requirements. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a precast reinforced concrete beam structure to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A precast reinforced concrete structural beam includes: a structural beam body, the outer wall of which is provided with a first angle steel and a second angle steel, the side wall of the first angle steel is fixedly provided with a screw, both ends of the first angle steel are provided with positioning components, and the top of the first angle steel is provided with a first lifting strap.

[0008] The first angle steel and the second angle steel are respectively installed at the top and bottom corners of the structural beam body, and the side walls of the first angle steel and the second angle steel are fixed with screws.

[0009] The first sling is "X" shaped, and each of the four corners of the first sling is provided with a fixing foot with a centrally located mounting hole that matches the screw rod. The four fixing feet are fitted onto the outer wall of the screw rod.

[0010] The outer wall of the screw is also fitted with a second lifting strap, and the other end of the second lifting strap is fitted inside the screw on the outer wall of the second angle steel. The screw is fixed to the fixing foot and the second lifting strap by a nut threaded to the outer wall.

[0011] A lifting ring is rotatably connected at the center of the top of the first sling, and the lifting ring passes through the bottom of the first sling and is provided with a baffle.

[0012] The positioning component includes a symmetrically arranged left mounting frame and a right mounting frame. The inner cavity of the left mounting frame and the right mounting frame is provided with a mounting plate. The top of the mounting plate is provided with a groove. The mounting plate at the other end of the first angle steel is fixedly provided with a protrusion.

[0013] The top of the left mounting frame is provided with a mounting groove, and the left mounting frame is connected to the mounting plate by bolts provided in the mounting groove.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] 1. In the above scheme, by installing the first angle steel and the second angle steel on the structural beam body, the four corners of the structural beam body can be protected. By putting the first lifting strap on the first angle steel, the structural beam body can be lifted. In order to ensure greater stability when lifting the structural beam body and to protect the first angle steel, the two ends of the second lifting strap are respectively put on the first angle steel and the second angle steel and fixed. This allows the weight of the structural beam body to be transferred to the second angle steel for distribution, thereby ensuring safety during lifting. After the lifting is completed, it can be disassembled.

[0016] 2. In the above scheme, by installing positioning components at both ends of the structural beam body, it is easier to splice the structural beam body and make it easier to insert the protrusion into the groove, thereby aligning the two structural beam bodies. After the structural beam bodies are aligned and installed, the left and right mounting frames can be removed by disassembling the bolts, thereby separating the positioning components and removing the positioning components for subsequent use.

However, this is only for illustrative purposes and is not intended to limit this utility model to the specific structure, device and environment. According to specific needs, those skilled in the art can adjust or modify these devices and environments, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0026] The precast reinforced concrete beam structure provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are listed as best and preferred embodiments; other alternative methods may be used by those skilled in the art. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0027] like Figure 1 and Figure 2As shown, an embodiment of this utility model provides a precast reinforced concrete structural beam structure, including: a structural beam body 1, a first angle steel 2 and a second angle steel 3 on the outer wall of the structural beam body 1, a screw 4 fixedly provided on the side wall of the first angle steel 2, positioning components 5 provided at both ends of the first angle steel 2, and a first lifting strap 6 provided on the top of the first angle steel 2.

[0028] like Figure 1 and Figure 2 As shown, the first angle steel 2 and the second angle steel 3 are respectively set at the top and bottom corners of the structural beam body 1. The side walls of the first angle steel 2 and the second angle steel 3 are fixed with screws 4. By setting the first angle steel 2 and the second angle steel 3, the four corners of the structural beam body 1 can be protected. The corners of the structural beam body 1 are relatively fragile and will be damaged by bumps.

[0029] like Figure 1 and Figure 5 As shown, the first sling 6 is "X" shaped, and each of the four corners of the first sling 6 is provided with a fixing foot 7 with a centrally located mounting hole that matches the screw 4. The four fixing feet 7 are fitted onto the outer wall of the screw 4. By being set in an "X" shape, the tension generated during lifting can be better distributed.

[0030] like Figure 1 and Figure 2 As shown, the outer wall of the screw 4 is also fitted with a second lifting strap 8, and the other end of the second lifting strap 8 is fitted inside the screw 4 on the outer wall of the second angle steel 3. The screw 4 is fixed to the fixing foot 7 and the second lifting strap 8 by the nut 9 connected by the thread on the outer wall. By fitting the two ends of the second lifting strap 8 onto the first angle steel 2 and the second angle steel 3 respectively and fixing them, the weight of the structural beam body 1 when it is lifted can be transferred to the second angle steel 3 for distribution, thereby ensuring safety during lifting.

[0031] like Figure 1 and Figure 3 As shown, a lifting ring 10 is rotatably connected to the center of the top of the first sling 6. The lifting ring 10 passes through the bottom of the first sling 6 and is provided with a baffle. The rotating first sling 6 facilitates the adjustment of direction and makes hoisting convenient.

[0032] like Figure 3 and Figure 5 As shown, the positioning component 5 includes a left mounting frame 51 and a right mounting frame 53 arranged symmetrically. The inner cavity of the left mounting frame 51 and the right mounting frame 53 is provided with a mounting plate 52. The top of the mounting plate 52 is provided with a groove 54. The mounting plate 52 at the other end of the first angle steel 2 is fixedly provided with a protrusion 55.

[0033] like Figure 4 and Figure 5 As shown, the top of the left mounting frame 51 is provided with a mounting groove, and the left mounting frame 51 is connected to the mounting plate 52 by bolts 56 provided in the mounting groove.

[0034] The technical solution provided by this utility model, during operation, protects the four corners of the structural beam body 1 by installing the first angle steel 2 and the second angle steel 3 on the structural beam body 1. The structural beam body 1 can be lifted by fitting the first lifting strap 6 onto the first angle steel 2. To ensure greater stability during lifting and to protect the first angle steel 2, the two ends of the second lifting strap 8 are respectively fitted onto the first angle steel 2 and the second angle steel 3 and fixed, thereby transferring the weight of the structural beam body 1 to the second angle steel 3 for distribution, ensuring safety during lifting. After lifting, it can be disassembled. By installing positioning components 5 at both ends of the structural beam body 1, it is easier to assemble the structural beam body 1, allowing the protrusion 55 to be inserted more easily into the groove 54, thus aligning the two structural beam bodies 1. After the structural beam bodies 1 are aligned and installed, the left mounting frame 51 and the right mounting frame 53 can be removed by disassembling the bolts 56, thus separating the positioning components 5 and facilitating subsequent use.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
