Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel construction, and in particular relates to a device for accurately aligning prefabricated components. Background Art

[0002] Prefabricated components are steel, wood or concrete components that are prefabricated in factories or on site according to design specifications. They come in many types, including concrete components, steel structural components, wood components, and composite panels. These components are widely used in many fields such as residential buildings, public buildings, bridges and tunnels, and industrial buildings.

[0003] Among them, the composite slab is one of the most common important prefabricated components, which has a wide range of application prospects in modern buildings. It is usually composed of two layers of reinforced concrete slabs and a thin layer of foam concrete sandwich in the middle. This structure gives the composite slab the characteristics of light weight, high strength, sound insulation, heat insulation and easy installation. The composite slab has a wide range of applications in the construction field, such as building walls, roofs, partitions, etc. Its main advantages are its structural strength, sound insulation and heat insulation performance, and construction convenience.

[0004] When installing the composite slabs, it is necessary to accurately align the installation positions of the composite slabs so that the width of the joints between the prefabricated composite slabs meets the design requirements. At the same time, it is also necessary to check the height difference between the joints after hoisting into place. If the height difference of the joints is too large, the hoisting operation will be required again, which is time-consuming and laborious. Utility Model Content

[0005] The purpose of the utility model is to provide a device for accurately aligning prefabricated components. By setting an infrared distance measuring mechanism, when the prefabricated components are lifted, the distance between the predetermined installation position and the adjacent prefabricated components is measured, thereby achieving accurate alignment and pre-adjusting the height of the installation point through an adjustable bracket, thereby reducing repeated lifting operations.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is specifically as follows:

[0007] A device for accurately aligning prefabricated components comprises a base and an infrared measuring mechanism arranged at the bottom of the base; the infrared measuring mechanism comprises at least two movable devices arranged in parallel and an infrared rangefinder respectively arranged on each movable device; the movable device comprises a mounting base plate, a driving wheel and a driven wheel respectively arranged at two ends of the mounting base plate, and a transmission chain is installed between the driving wheel and the driven wheel, a driving motor is installed on one side of the base plate, and the output shaft of the driving motor is connected to the driving wheel; a moving block is connected to the transmission chain, and a mounting base of the infrared rangefinder is arranged on the moving block.

[0008] Furthermore, a lifting ring is arranged above the base, and lifting rings are evenly arranged at the four corners below the base.

[0009] Furthermore, each lifting ring is connected to a lifting point of the prefabricated component through a lifting chain.

[0010] Furthermore, the infrared rangefinder is mounted on a mounting base on the moving block with the measuring head facing downward.

[0011] Furthermore, a drive motor mounting bracket is provided at one end of the mounting base plate, and a plurality of connecting threaded blind holes are provided on the drive motor mounting bracket.

[0012] Furthermore, the drive motor mounting bracket is connected to the bottom of the base.

[0013] Compared with the prior art, the utility model has the advantages that: the utility model uses at least two miniaturized infrared rangefinders to measure the preset installation position and the adjacent already installed composite panels simultaneously. On the one hand, the infrared ray points emitted by the infrared rangefinder can be used as alignment guides to meet the joint width requirements between adjacent composite panels; at the same time, on the other hand, by calculating whether the height difference between the adjacent composite panels and the installation position meets the thickness of the composite panels, it is determined whether the height difference of the bottom joints of the adjacent composite panels after being hoisted in place meets the design requirements, so that the height of the installation point can be adjusted by the adjustable bracket before the hoisting is completed, thereby effectively avoiding repeated hoisting operations.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0026] like Figure 1-Figure 2As shown, the equipment for accurate positioning of prefabricated components comprises a base 1 and an infrared measuring mechanism arranged at the bottom of the base 1; the infrared measuring mechanism comprises at least two moving devices arranged in parallel and an infrared rangefinder respectively arranged on each moving device; the moving device comprises a mounting base plate 3, a driving wheel 6 and a driven wheel 8 respectively arranged at both ends of the mounting base plate 3, and a transmission chain 7 is installed between the driving wheel 6 and the driven wheel 8, a driving motor 4 is installed on one side of the base plate, and the output shaft of the driving motor 4 is connected to the driving wheel 6; a moving block is connected to the transmission chain 7, and a mounting base 9 of the infrared rangefinder is arranged on the moving block.

[0027] Compared with the prior art, in the prior art, the alignment of prefabricated components mainly relies on manual alignment and installation. The main technical means used is to accurately lay out the positioning edge lines of the prefabricated components according to the construction drawings and positioning axes. Especially in the installation process of the composite board, its supporting components are complex and there may be height differences in the installation points. Therefore, it is necessary to measure the joint height of the bottom plate after the composite board is hoisted in place to detect whether it meets the design requirements. If it does not meet the design requirements, it is necessary to lift the composite board again and adjust it through the adjustable bottom support until the joint height difference at the bottom of the adjacent composite boards meets the design requirements. In the present invention, a movable installation mechanism is used to drive the infrared rangefinder to the specified installation position. Before hoisting into place, the distance to the adjacent installed composite panels and the distance to the installation point are measured respectively, and the distance difference is compared with the thickness of the composite panels to determine whether the height difference between the bottom seams of the composite panels and the adjacent composite panels after the composite panels are hoisted into place meets the design requirements. Therefore, adjustments can be made before hoisting into place, avoiding repeated lifting and installation, achieving precise alignment, and improving construction efficiency.

[0028] A lifting ring 2 is provided above the base 1, and lifting rings are evenly distributed at the four corners below the base 1. Each lifting ring is connected to the lifting point of the prefabricated component through a lifting chain. By connecting multiple lifting rings to the lifting points, the composite plate can be evenly stressed when lifted.

[0029] The infrared rangefinder is mounted on the mounting base 9 on the moving block with the measuring head facing downward. A drive motor 4 mounting bracket is provided at one end of the mounting base 3, and a plurality of connecting threaded blind holes are provided on the drive motor 4 mounting bracket. The drive motor 4 mounting bracket is connected to the bottom of the base 1.

[0030] During the specific construction, it is first necessary to check the type of composite board components according to the construction drawings, determine the installation position, and number the order of composite board hoisting, and prepare the prefabricated components in the factory. Before the prefabricated components arrive at the site, build the support system according to the construction plan, adjust the support elevation to the design elevation, and check the support system before hoisting to ensure that its force is stable and the elevation is accurate. Then the composite board is hoisted. During the hoisting, the precise alignment device provided by the utility model is set between the lifting device and the composite board, and the lifting position is marked on the composite board, and connected to the lifting ring below the base 1 provided by the utility model through a chain. During the hoisting, trial hoisting is given priority, and the hoisting height is 500mm above the ground to check whether the force is balanced and whether it can be kept horizontal. After the conditions are met, it is hoisted to the air above the working layer and stopped at 300mm above the working layer. At this time, the infrared rangefinder is adjusted to the adjacent installed composite board and the end of the installation point of the composite board by driving motor 4 for measurement. The distance difference is compared with the thickness of the composite board to determine whether the height difference between the bottom seam of the composite board and the adjacent composite board meets the design requirements after the composite board is hoisted into place. Therefore, the adjustable base can be used for adjustment before hoisting into place, avoiding repeated lifting and installation, achieving precise alignment, and improving construction efficiency.
