Description

Technical Field

[0001] This utility model relates to the field of precast wall diagonal bracing reinforcement technology, and in particular to a precast wall diagonal bracing reinforcement device with factory-installed embedded parts. Background Technology

[0002] Compared to traditional construction methods, prefabricated buildings have most of their main structural components produced modularly on factory assembly lines, significantly reducing on-site pouring work, greatly reducing construction waste, and effectively shortening the construction period. Prefabricated buildings generally include prefabricated exterior walls, prefabricated interior walls, prefabricated floor slabs, prefabricated stairs, prefabricated beams, etc.

[0003] Traditionally, the installation methods for various types of precast walls generally involve embedding steel reinforcement rings at predetermined positions on the floor slab. After the precast wall is hoisted and its elevation, verticality, and flatness are adjusted and tested, it is installed using diagonal bracing steel pipes and the embedded steel reinforcement rings, and reinforced with four-point support. Although this method can support the precast wall during installation, it requires a large amount of steel reinforcement rings, resulting in high costs. Furthermore, when the diagonal bracing steel pipes are removed after the precast wall connection nodes are completed and have reached sufficient strength, the embedded steel reinforcement rings on the ground need to be cut, increasing the need for hot work on the work surface and reducing efficiency. Utility Model Content

[0004] Based on this, it is necessary to provide a precast wall bracing reinforcement device with factory-prefabricated embedded parts to address the problems of high cost, high cost, and the need to cut the ground steel reinforcement embedded rings when removing the diagonal bracing steel pipes after the precast wall connection node construction is completed and the strength is reached. This increases the need for hot work on the work surface and is inefficient.

[0005] It includes: two reinforcement mechanisms; wherein, the reinforcement mechanism includes two sleeves pre-embedded in the precast wall panel and one sleeve pre-embedded in the precast layer of the composite slab, a long diagonal brace, a short diagonal brace, and three anchor plates, the inner walls of the anchor plates are threaded with bolts, two of the anchor plates are fixedly connected to the surface of an inner anchor ring, and the surface of the other anchor plate is fixedly connected to an inner anchor ring and an outer anchor ring, and the ends of the long diagonal brace and the ends of the short diagonal brace are fixedly connected to hooks, which are connected to the corresponding inner and outer anchor rings by means of hooks.

[0006] In one embodiment, both ends of the long diagonal brace and both ends of the short diagonal brace are threadedly connected with limit nuts and reinforcing nuts, with the limit nuts close to the hooks. This facilitates the limiting of the hooks during use, while also limiting the connection areas between the inner and outer anchor rings and the corresponding hooks, and the limit nuts are tightened and reinforced by the reinforcing nuts.

[0007] In one embodiment, the angle formed between the long diagonal brace and the horizontal plane is greater than the angle formed between the short diagonal brace and the horizontal plane, and the long and short diagonal braces form a triangle with the horizontal or vertical plane. During the reinforcement mechanism's support of the precast wall panel, the long and short diagonal braces form multiple triangles with the horizontal and vertical planes for support, ensuring the stability of the precast wall panel support.

[0008] In one embodiment, both ends of the long diagonal brace and both ends of the short diagonal brace are threaded, and the limiting nut and the reinforcing nut are connected to the corresponding long diagonal brace and short diagonal brace via the threads. This ensures a stable connection between the limiting nut, the fixing nut, and the corresponding long diagonal brace and short diagonal brace.

[0009] In one embodiment, the outer diameter of the hook is smaller than the inner diameter of the limiting nut and the reinforcing nut. This facilitates the replacement of the limiting nut and the reinforcing nut according to actual usage requirements.

[0010] In one embodiment, the inner and outer anchor rings are fixedly connected to the corresponding anchor plates by welding, ensuring the stability of the connection between the inner and outer anchor rings and the anchor plates.

[0011] In one embodiment, both the long diagonal brace and the short diagonal brace have through holes at the center of their surfaces. This facilitates further reinforcement of the reinforcement mechanism during use.

[0012] In one embodiment, the other anchor plate takes on a slingshot shape due to the interaction of the inner anchor ring, outer anchor ring, and bolts. This avoids interference between the long and short diagonal braces and the double-ring anchor plate during installation. Beneficial effects

[0013] 1. The above-mentioned reinforcement mechanism, by installing single-ring anchor plates and double-ring anchor plates with pre-embedded sleeves, and installing long and short diagonal braces with single-ring and double-ring anchor plates, facilitates the support and reinforcement of precast wall panels. When the precast components are connected as a whole and the design allows for the removal of the reinforcement mechanism, the sleeve is embedded in the concrete, and the bolts, anchor plates, long diagonal braces, and short diagonal braces inside the sleeve can be removed. The disassembled components can be recycled, and when the reinforcement mechanism is removed, there is no need to perform the traditional pre-embedded ring cutting work. Compared with the traditional reinforcement method of pre-embedded steel bars, the use of standardized tools such as sleeves, single-ring anchor plates, and double-ring anchor plates makes the construction simple and efficient, reduces construction costs, and improves work efficiency. 2. The above-mentioned reinforcement mechanism further accelerates the on-site construction progress and improves the pre-embedding accuracy by pre-embedding the sleeve in the precast layer. It also has high strength and is safer and more reliable in the process of diagonal bracing reinforcement after installation with the anchor plate. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined with Figures 1-5 This invention describes a precast wall diagonal bracing reinforcement device with factory-installed embedded parts.

[0019] In one embodiment, a precast wall diagonal bracing reinforcement device with factory-installed embedded parts includes: two reinforcement mechanisms 100; wherein, the reinforcement mechanism 100 includes two sleeves 110 embedded in the precast wall panel and one sleeve 110 embedded in the precast layer of the composite slab, a long diagonal brace 120, a short diagonal brace 130, and three anchor plates 140, the inner walls of the anchor plates 140 are threaded with bolts 141, the surfaces of two anchor plates 140 are fixedly connected with inner anchor rings 150, the surface of the other anchor plate 140 is fixedly connected with an inner anchor ring 150 and an outer anchor ring 151, the ends of the long diagonal brace 120 and the ends of the short diagonal brace 130 are fixedly connected with hooks 160, and the hooks 160 are connected to the corresponding inner anchor rings 150 and outer anchor rings 151.

[0020] In this embodiment, two of them are single-ring anchor plates 140 with only inner anchor rings 150 installed, and the other is a double-ring anchor plate 140 with both inner anchor ring 150 and outer anchor ring 151 installed. The bolts 141 match the mounting holes opened in the sleeve 110.

[0021] In this device, during the prefabrication of precast walls and composite slabs, threaded sleeves 110 are installed in preset positions simultaneously, and the top elevation of the sleeves 110 embedded in the composite slab is higher than the surface of the composite slab, generally flush with the surface of the cast-in-place layer of the composite slab, or slightly higher than the surface of the cast-in-place slab. When inspecting the installation of the composite slab, the position of the embedded part of the sleeve 110 should be checked, and attention should be paid to the installation direction of the composite slab to avoid the installation deviation of the composite slab causing the double ring anchor plate 140 to be unable to be installed properly later. After the composite slab is installed, before the cast-in-place concrete is poured, the bolt 141 should be threaded to the sleeve 110 embedded in the composite slab to seal the hole of the sleeve 110, so as to prevent cement slurry from flowing into the sleeve 110 during the pouring process and causing blockage.

[0022] It should be noted that after the composite slab is hoisted, the elevation of the bottom support frame is checked and adjusted to ensure that the bottom elevation of the composite slab is within the allowable deviation range. At this time, the top elevation of sleeve 110 is the surface elevation of the cast-in-place layer of the composite slab. When the cast-in-place layer is poured, this can be used as a reference to control the surface elevation, which can greatly improve the accuracy of the surface elevation and thickness of the slab.

[0023] During use, the device utilizes two reinforcement mechanisms 100 to achieve four-point support and reinforcement of the precast wall.

[0024] like Figure 3 and Figure 4As shown, both ends of the long diagonal brace 120 and both ends of the short diagonal brace 130 are threadedly connected to a limiting nut 170 and a reinforcing nut 180, with the limiting nut 170 located near the hook 160. Both ends of the long diagonal brace 120 and both ends of the short diagonal brace 130 are threaded, and the limiting nut 170 and the reinforcing nut 180 are connected to the corresponding long diagonal brace 120 and short diagonal brace 130 via these threads.

[0025] In this embodiment, in the initial state, the limiting nut 170 is away from the hook 160 at the corresponding position, so that the inner anchor ring 150 or the outer anchor ring 151 can enter the inner side of the corresponding hook 160. Furthermore, the surfaces of the limiting nut 170 and the reinforcing nut 180 are both fixedly connected with hexagonal rings. When the operator turns the limiting nut 170 or the reinforcing nut 180, they can use existing turning tools or turn it manually.

[0026] After the inner anchor ring 150 or the outer anchor ring 151 is connected to the corresponding hook 160, the limiting nut 170 and the reinforcing nut 180 at the corresponding positions of the hook 160 are rotated in sequence so that the open end of the hook 160 enters the inside of the limiting nut 170. The limiting nut 170 limits the movable area at the connection between the inner anchor ring 150 or the outer anchor ring 151 and the corresponding hook 160, and the reinforcing nut 180 is used to tighten and limit the limiting nut 170.

[0027] like Figure 5 As shown, the angle formed between the long diagonal brace 120 and the horizontal plane is greater than the angle formed between the short diagonal brace 130 and the horizontal plane, and the long diagonal brace 120, the short diagonal brace 130 and the horizontal or vertical plane form a triangle.

[0028] In this embodiment, the angle formed between the long diagonal brace 120 and the vertical plane is smaller than the angle formed between the short diagonal brace 130 and the vertical plane.

[0029] like Figure 4 As shown, the outer diameter of the hook 160 is smaller than the inner diameter of the limiting nut 170 and the reinforcing nut 180.

[0030] In this embodiment, when it is necessary to replace the limiting nut 170 or the reinforcing nut 180, the limiting nut 170 and the reinforcing nut 180 can be rotated and moved away from the corresponding long diagonal brace 120 or short diagonal brace 130, so that the limiting nut 170 and the reinforcing nut 180 can be disassembled from the corresponding long diagonal brace 120 or short diagonal brace 130.

[0031] like Figure 3 As shown, the inner anchor ring 150 and the outer anchor ring 151 are fixedly connected to the corresponding anchor plate 140 by welding. Welding is a relatively mature connection process in the existing technology.

[0032] like Figure 3 As shown, through holes 190 are provided in the middle of the surface of the long diagonal brace 120 and the middle of the surface of the short diagonal brace 130.

[0033] In this embodiment, if it is necessary to increase the support strength of the long diagonal brace 120 or the short diagonal brace 130 during the support process, two connecting rods can be used to transversely penetrate the through holes 190 of the two long diagonal braces 120 and the through holes 190 of the two short diagonal braces 130 in the two reinforcement mechanisms 100, thereby connecting the two long diagonal braces 120 and the two short diagonal braces 130 into a whole. This operation can be selected and used according to actual usage requirements.

[0034] like Figure 3 As shown, the other anchor plate 140 has an overall slingshot shape due to the interaction of the inner anchor ring 150, the outer anchor ring 151 and the bolt 141.

[0035] In this embodiment, when the inner anchor ring 150, the outer anchor ring 151 and the anchor plate 140 are installed, the tilt angle of the outer anchor ring 151 is greater than the tilt angle of the inner anchor ring 150. Therefore, after the end of the long diagonal brace 120 is installed with the outer anchor ring 151, it does not affect the short diagonal brace 130.

[0036] Working principle: When using the reinforcement mechanism 100 for support, after the composite slab is installed and poured, bolts 141 are used to longitudinally penetrate the double-ring anchor plate 140 and the sleeve 110 embedded in the composite slab and tighten them, thereby installing and fixing the double-ring anchor plate 140 and the sleeve 110 embedded in the composite slab, so that the double-ring anchor plate 140 is fixed to the floor slab surface. After the precast wall panel is hoisted, bolts 141 are used to transversely penetrate the single-ring anchor plate 140 and the sleeve 110 embedded in the precast wall panel and tighten them, thereby installing and fixing the single-ring anchor plate 140 and the sleeve 110 embedded in the precast wall panel, so that the single-ring anchor plate 140 is fixed to the wall. After completing this operation, the two hooks 160 at the end of the short diagonal brace 130 are respectively installed with the inner anchor rings 150 in the single-ring anchor plate 140 and double-ring anchor plate 140 located below. The two hooks 160 at the end of the long diagonal brace 120 are respectively installed with the outer anchor rings 151 in the single-ring anchor plate 140 and double-ring anchor plate 140 located above. After installation, the corresponding hooks 160 are limited by the limiting nuts 170 and reinforcing nuts 180 at the ends of the long diagonal brace 120 and the short diagonal brace 130. After completing this operation, the reinforcement mechanism 100 can support the precast wall panel.

[0037] When the prefabricated components of the floor are connected as a whole and the design allows for the removal of the reinforcement mechanism 100, the long diagonal brace 120, the short diagonal brace 130 and the anchor plate 140 are removed, and the holes of the sleeves 110 embedded in the composite slab and prefabricated wall panel are sealed with dry hard cement mortar or waterproof mortar. The long diagonal brace 120, the short diagonal brace 130 and the anchor plate 140 can be reused repeatedly.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model 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 of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
