Description

Technical Field

[0001] The utility model relates to a steel bar positioning device for prefabricated components, belonging to the technical field of auxiliary equipment for the production of reinforced concrete prefabricated components. Background Art

[0002] At present, as fewer and fewer people are working on construction sites, prefabricated buildings are increasingly showing their superiority. In reinforced concrete structures, prefabricated components (prefabricated components) include shear walls, columns, beams, slabs, stairs and decorative components. Due to the complex node connections of prefabricated components, the quality is difficult to control and difficult to detect, which leads to serious restrictions on the use of prefabricated reinforced concrete components.

[0003] For vertical components (columns, walls, etc.), the connection methods currently used include steel sleeve connection, grout anchor connection, etc., all of which have problems such as difficult quality assurance and difficult construction. An efficient and convenient node connection method is urgently needed. Among them, mechanical sleeve connection has the characteristics of simple construction and high efficiency, but if mechanical sleeve connection is used, the protruding steel bars in the prefabricated components must be positioned very accurately, otherwise the construction efficiency will be greatly reduced. Therefore, how to improve the precise positioning of the protruding steel bars of the prefabricated components is the key to using the sleeve connection method. Utility Model Content

The specific technical solution is as follows.

[0006] Furthermore, the positioning rod is a screw rod or a steel bar with external threads.

[0007] Furthermore, the length of the external thread on the positioning rod is not less than the length of the positioning sleeve, so as to ensure that the entire positioning sleeve is sleeved on the positioning rod.

[0008] Furthermore, the positioning rod is fixed to the positioning end plate by welding.

[0009] Further, the positioning rod is detachably arranged on the positioning end plate. Preferably, a positioning through hole is provided on the positioning end plate, and the positioning rod is fixed to the positioning end plate by a fastener. The positioning rod is detachably arranged on the positioning end plate, which is conducive to adjusting the number and position of the positioning rods according to prefabricated components of different specifications, thereby improving the adaptability of the positioning device.

[0010] Furthermore, the positioning sleeve is made of plastic or steel.

[0011] The specific working principle of the positioning device of the utility model will be described in detail in the specific implementation method section. The utility model has the characteristics of simple structure and low cost, and can play a good role in positioning the protruding steel bars of the prefabricated components, even to the micron level, which is conducive to improving the construction efficiency and construction quality of the prefabricated components when they are subsequently connected by sleeves.

[0022] The utility model is described in further detail below in conjunction with the accompanying drawings.

[0023] See also Figure 1-Figure 3 A steel bar positioning device for prefabricated components includes a positioning end plate 1, a positioning rod 2 and a positioning sleeve 3. A plurality of positioning rods 2 are arranged on the positioning end plate 1; the extending direction of the positioning rod 2 is perpendicular to the plane where the positioning end plate 1 is located, the positioning rod 2 is provided with an external thread, the positioning sleeve 3 has an internal thread through hole, and the positioning sleeve 3 is threadedly connected to the positioning rod 2.

[0024] Preferably, the positioning rod 2 is a screw rod or a steel bar with external threads.

[0025] Preferably, the length of the external thread on the positioning rod 2 is not less than the length of the positioning sleeve 3. This ensures that the entire positioning sleeve 3 is sleeved on the positioning rod 2.

[0026] Among them, the positioning rod 2 can be fixed to the positioning end plate 1 by welding. Or the positioning rod 2 can be detachably arranged on the positioning end plate 1. A positioning through hole (not shown) can be opened on the positioning end plate 1, and the positioning rod 2 is fixed to the positioning end plate 1 by a fastener. There are many ways to implement the positioning rod 2 to be detachably fixed to the positioning end plate 1 by a fastener, such as the positioning rod 2 is passed through the positioning through hole and then locked by a nut (a type of fastener), or the positioning rod 2 has an internal screw hole inside, and a screw (a type of fastener) is passed through the positioning through hole and then fastened to the positioning rod thread. The positioning rod 2 is detachably arranged on the positioning end plate 1, which is conducive to adjusting the number and position of the positioning rods 2 according to prefabricated components 6 of different specifications, thereby improving the adaptability of the positioning device.

[0027] The positioning sleeve 3 can be made of plastic or steel, etc. The material and shape of the positioning end plate 1 are not limited, as long as it can provide support for the positioning rod 2.

[0028] The working principle (method) of the steel bar positioning device of the utility model is as follows.

[0029] 1. The steel frame (steel cage) to be positioned usually includes longitudinal steel bars 4 and transverse steel bars 5, such as Figure 4 The two ends of the longitudinal reinforcement 4 to be positioned have external threads (formed by threading at the ends of the longitudinal reinforcement 4).

[0030] 2. Make preparations for the connection between the positioning device and the steel frame, such as Figure 5 Before butt jointing, the longitudinal reinforcement 4 of the reinforcement skeleton can be adjusted according to the position of the positioning rod 2 of the positioning device.

[0031] 3. When the positioning rod 2 corresponds to the longitudinal reinforcement 3 one by one, unscrew the positioning sleeve 3 on the positioning rod 2, and the positioning sleeve 3 is threadedly connected with the longitudinal reinforcement 3 of the prefabricated component 6, such as Figure 6As shown. Since the longitudinal reinforcement 3 of the prefabricated component 6 corresponds to the positioning rod 2 of the positioning device, the positioning accuracy of the positioning rod 2 of the positioning device is basically consistent with the positioning accuracy of the longitudinal reinforcement 3 of the prefabricated component 6, which can reach the micron level.

[0032] 4. Concrete pouring. During the pouring process, the positioning device and the precast member 6 are kept as a whole, and both ends of the longitudinal steel bar 3 extend out of the concrete to become protruding steel bars, which are convenient for connection with other precast members. Figure 7 shown.

[0033] 5. After the concrete pouring is completed, the positioning sleeve 3 of the positioning device rotates back to the positioning rod 2 and separates from the longitudinal reinforcement 3 of the prefabricated component 6. Figure 8 shown.

[0034] 6. The prefabricated component 6 is produced. During the production process, the longitudinal reinforcement 3 maintains integrity with the positioning device, and its positioning accuracy is consistent with the accuracy of the positioning rod 2 of the positioning device, such as Fig. 9 shown.
