Description

Technical Field

[0001] This utility model relates to the field of prefabricated exterior wall components, and in particular to a prefabricated exterior wall component for energy-saving buildings. Background Technology

[0002] Precast concrete components, also known as PC components, are concrete products manufactured in factories using standardized and mechanized methods. In contrast, traditional cast-in-place concrete requires on-site molding, pouring, and curing. Precast concrete components are widely used in construction, transportation, water conservancy, and other fields, playing an important role in the national economy. Examples include precast reinforced concrete column foundations, precast steel structure column foundations, reinforced concrete foundations for streetlights and billboards, precast floor slabs, and precast exterior wall panels, which are manufactured in factories and then transported to the construction site for assembly.

[0003] In the prior art, such as Chinese patent CN218580997U, a prefabricated component for energy-saving building exterior walls is disclosed, including a wall, connecting pieces, connecting blocks, moisture-proof boards, sound insulation boards, fireproof boards, solar panels, and socket bodies; the bottom of the wall is fixedly provided with connecting pieces, both sides of the wall are fixedly provided with connecting blocks, the interior of the wall is provided with moisture-proof boards and sound insulation boards, one side of the wall is provided with a fireproof board, the surface of the fireproof board is provided with a socket body, and the other side of the wall is provided with a solar panel.

[0004] However, in the existing technology, when fixing prefabricated components for energy-saving building exterior walls, two adjacent prefabricated components are fixed with bolts. The installation requires tightening multiple fixing bolts, which is a cumbersome installation method and results in low efficiency in installing prefabricated components for energy-saving building exterior walls. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that in the existing technology, when fixing two adjacent prefabricated components for building energy-saving exterior walls, they are all fixed with bolts, and the installation requires tightening multiple fixing bolts, which is a relatively cumbersome installation method and thus has low efficiency in installing prefabricated components for building energy-saving exterior walls. Therefore, this utility model proposes a prefabricated component for building energy-saving exterior walls.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a prefabricated exterior wall component for energy conservation, comprising a first prefabricated component, a second prefabricated component disposed at the upper end of the first prefabricated component, a locking block fixedly connected to one side of the first prefabricated component, a limiting groove formed at the lower end of the locking block, a lifting plate locked to the inner wall of the limiting groove, a sliding rod fixedly connected to the lower end of the lifting plate, a first irregular block fixedly connected to one end of the sliding rod, a fixing slot formed on the other side of the first prefabricated component, a fixing groove formed on one side of the inner wall of the fixing slot, an installation box disposed on one side of the inner wall of the locking block, a first fixing rod slidably connected to one side of the inner wall of the installation box, and one side of the first fixing rod slidably connected to one side of the first irregular block.

[0007] Preferably, a fixing ring is fixedly connected to one side of the outer wall of the first fixing rod, and a first spring is fixedly connected to one side of the fixing ring. One end of the first spring is fixedly connected to the inner wall of the mounting box.

[0008] Preferably, the other side of the inner wall of the mounting box is slidably connected to one side of the outer wall of the sliding rod.

[0009] Preferably, a second fixing rod is slidably connected to the other side of the first irregular block, and the outer wall of the second fixing rod is slidably connected to one side of the first irregular block.

[0010] Preferably, a second spring is sleeved on the other side of the outer wall of the sliding rod. One end of the second spring is fixedly connected to the lower end of the lifting plate, and the other end of the second spring is attached to the upper end of the locking block.

[0011] Preferably, the second precast component has internally fixed reinforcing bars, and a fixing hole is provided at the lower end of the second precast component.

[0012] Preferably, a connecting rod is fixedly connected to the lower end of the first irregular block, and a second irregular block is fixedly connected to one end of the connecting rod.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up the locking block and the fixing slot, when installing the precast exterior wall components, firstly, the first precast component is fixed on the foundation. Then, a crane is used to lift another precast component, and the locking block on the other precast component is locked into the fixing slot on the first precast component. Then, the crane is used to lift the second precast component, and the limiting groove on the second precast component is aligned with the lifting plate on the first precast component. The second precast component is then lowered, and the sliding rod moves downward. The first irregular block will push the first fixing rod and the second fixing rod, locking the first fixing rod into the fixing slot, thus fixing the two adjacent precast components, making installation convenient and improving installation efficiency.

[0015] 2. In this utility model, by setting up spring No. 1 and spring No. 2, when the prefabricated component is installed incorrectly, the second prefabricated component is lifted by a crane, spring No. 2 will lift the lifting plate, and spring No. 1 will push the first fixing rod into the installation box for disassembly. Thus, the cooperation between spring No. 1 and spring No. 2 facilitates the disassembly of the prefabricated component. Attached Figure Description

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example

[0024] like Figure 1-5As shown, this utility model provides a prefabricated exterior wall component for energy conservation, including a first prefabricated component 1, a second prefabricated component 2 at the upper end of the first prefabricated component 1, a locking block 3 fixedly connected to one side of the first prefabricated component 1, a limiting groove 31 at the lower end of the locking block 3, a lifting plate 6 locked to the inner wall of the limiting groove 31, a sliding rod 45 fixedly connected to the lower end of the lifting plate 6, a first irregular block 44 fixedly connected to one end of the sliding rod 45, a fixing slot 5 on the other side of the first prefabricated component 1, a fixing groove 51 on one side of the inner wall of the fixing slot 5, an installation box 41 on one side of the inner wall of the locking block 3, a first fixing rod 4 slidably connected to one side of the inner wall of the installation box 41, and one side of the first fixing rod 4 slidably connected to one side of the first irregular block 44.

[0025] The specific settings and functions of this embodiment are described below. When installing prefabricated exterior wall components using the locking block 3 and the fixing slot 5, the first prefabricated component 1 is first fixed on the foundation. Another prefabricated component 1 is then lifted by a crane. The locking block 3 on the other prefabricated component 1 is then locked into the fixing slot 5 on the first prefabricated component 1. Then, the second prefabricated component 2 is lifted by a crane. The limiting groove 31 on the second prefabricated component 2 is aligned with the lifting plate 6 on the first prefabricated component 1. The second prefabricated component 2 is then lowered. The sliding rod 45 moves downward, and the first irregular block 44 pushes the first fixing rod 4 and the second fixing rod 47, locking the first fixing rod 4 into the fixing groove 51. This fixes the two adjacent prefabricated components, making installation convenient and improving installation efficiency. The first prefabricated component 1 and the second prefabricated component 2 have the same structure. Example

[0026] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a fixing ring 43 is fixedly connected to one side of the outer wall of the first fixing rod 4, and a first spring 42 is fixedly connected to one side of the fixing ring 43. One end of the first spring 42 is fixedly connected to the inner wall of the mounting box 41, and the other side of the inner wall of the mounting box 41 is slidably connected to one side of the outer wall of the sliding rod 45. A second fixing rod 47 is slidably connected to the other side of the first irregular block 44, and the outer wall of the second fixing rod 47 is slidably connected to one side of the first irregular block 44. A second spring 46 is sleeved on the other side of the outer wall of the sliding rod 45. One end of the second spring 46 is fixedly connected to the lower end of the lifting plate 6, and the other end of the second spring 46 is attached to the upper end of the clamping block 3. A reinforcing steel bar 21 is fixedly connected inside the second precast component 2. A fixing hole 22 is opened at the lower end of the second precast component 2. A connecting rod 7 is fixedly connected to the lower end of the first irregular block 44, and a second irregular block 71 is fixedly connected to one end of the connecting rod 7.

[0027] The overall effect of this embodiment is that, through the setting of spring 42 and spring 46, when the prefabricated component is installed incorrectly, the second prefabricated component 2 is lifted by a crane, spring 46 will lift the lifting plate 6, and spring 42 will push the first fixing rod 4 into the mounting box 41 for disassembly. Thus, the cooperation between spring 42 and spring 46 facilitates the disassembly of the prefabricated component. The mounting box 41 is equipped with four first fixing rods 4 and second fixing rods 47, each with the same structure.

[0028] The usage and working principle of this device are as follows: When installing precast exterior wall components, first fix precast component 1 (No. 1) to the foundation. Use a crane to lift another precast component 1 (No. 1). Secure the locking block 3 on the other precast component 1 into the fixing slot 5 on the first precast component 1. Once one layer of precast component 1 is installed, use a crane to lift precast component 2 (No. 2). Align the limiting groove 31 on precast component 2 with the lifting plate 6 on precast component 1. Lower precast component 2 and slide it. When rod 45 moves downward, the first irregular block 44 will push the first fixing rod 4 and the second fixing rod 47, locking the first fixing rod 4 into the fixing groove 51, thus fixing two adjacent precast components. The same operation is performed on other precast components of the exterior wall. When a precast component is installed incorrectly, the second precast component 2 is lifted by a crane. The second spring 46 will lift the lifting plate 6, and the first spring 42 will push the first fixing rod 4 into the installation box 41 for disassembly, which facilitates the disassembly of the precast component.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
