DETAILED DESCRIPTION

[0025] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below. The technical features in each embodiment of the present application can be combined accordingly without conflict.

[0026] As shown in Figure 1 and Figure 2 As a preferred embodiment of the present application, the present embodiment provides a suspended formwork sliding type stripping device for core tube vertical structure construction, which comprises a connecting beam 1, a fixing device 4, a sliding mechanism 5 and a hoisting device 6.

[0027] The utility model provides a device, the connecting beam 1 includes two connecting section steels, can adopt channel steel specifically. The opening direction of two connecting section steels is opposite, and the web of connecting section steel is parallel and interval arrangement. The length of two connecting section steels can be adjusted according to the actual space requirement of the construction site, and after the length adjustment, the cross section design of the section steel must be determined through accurate calculation to ensure the stability and functionality of its structure. Two connecting section steels are connected and fixed through end plate 2 and connecting plate 3. The connecting plate 3 is vertically fixed between the end of two connecting section steels, and the both ends of connecting plate 3 are fixedly connected with the web of two connecting section steels. The other end of connecting beam 1 is vertically fixed with end plate 2, and end plate 2 is fixedly connected with the upper flange and lower flange of two connecting section steels. End plate 2 covers the end section of two connecting section steels, to prevent the sliding mechanism 5 from falling off when moving to the end of connecting beam 1. Connecting plate 3 and end plate 2 are generally fixedly connected with connecting beam 1 by welding. The upper and lower flanges of one end of two connecting section steels close to connecting plate 3 are provided with connecting holes, and the connecting beam 1 and the top column structure of the building machine are fixedly connected by fixing piece 4 passing through the connecting holes. The fixing piece 4 can adopt bolts and matched nuts. The suspension formwork sliding type stripping device of the whole core tube vertical structure construction is fixedly connected with the top column structure of the building machine by fixing piece 4, and when the construction of the current floor structure is completed, the building machine can be lifted with the device and the whole steel frame of the building machine is lifted synchronously. At the same time, the fixing piece 4 can prevent the sliding mechanism 5 from falling off when moving to the end of connecting beam 1 close to connecting plate 3.

[0028] In the device, a plurality of limiting holes for passing through limiting pins are arranged on the webs of the two connecting section steels, and the plurality of limiting holes are uniformly distributed along the length direction of the connecting section steel. The distance between every two limiting holes can be adjusted according to actual construction requirements. By inserting the limiting pin into the corresponding limiting hole, the movement range of the sliding mechanism 5 on the connecting beam 1 is limited, and the sliding mechanism 5 is prevented from moving during the construction process, so that the position of the formwork is changed, thereby affecting the construction operation.

[0029] In the device, when the space requirement of the upper structure needs to be adjusted and the length of the two connecting section steels is relatively long, the bearing capacity and safety degree of each component are considered, and the reinforcing mechanism 7 is arranged on the lower surface of the two connecting section steels instead of the fixing piece 4. Figure 3As shown, the reinforcing mechanism 7 is fixedly installed at the bottom of the connecting beam 1. The reinforcing mechanism 7 includes a reinforcing bolt 71 and a clamping plate 72. The width of the clamping plate 72 is greater than the distance between the webs of the two connecting steel sections. The clamping plate 72 contacts the bottom of the connecting beam 1 and has through holes. The reinforcing bolt 71 passes through the through holes and the gap between the two connecting steel sections to be fixedly connected to the top column structure of the building machine. In this embodiment, several reinforcing mechanisms 7 are provided. One reinforcing mechanism 7 can be fixed to the bottom of each end of the connecting beam 1 to achieve a stable connection effect. Reinforcing mechanisms 7 can be added to the middle part of the connecting beam 1 according to the actual construction requirements. The reinforcing mechanisms 7 set in the middle part of the connecting beam 1 can move and replace the function of the limiting pin to restrict the sliding mechanism 5.

[0030] like Figure 4 As shown, in the device provided in this embodiment, the sliding mechanism 5 includes a base plate 51, a connecting vertical plate 52, side plates 54, and rollers 55.

One end of the connecting shaft passes through the mounting hole and is fixedly connected to the side plate 54 by plugging and welding. The other end has a roller 55, located inside the two side plates 54, forming a rotatable connection between the rollers 55 and the connecting shaft. The two rollers 55 are respectively positioned between the upper and lower flanges of the two connecting steel sections, forming a sliding connection with the connecting beam 1. During the demolding operation after structural pouring and curing, after the lower formwork's bolts are safely removed, the sliding mechanism 5 is pushed to the side of the connecting beam 1 near the connecting plate 3, causing the formwork to move with the sliding mechanism 5, thus allowing the entire formwork to be smoothly demolded. If construction of the upper structure is required, the sliding mechanism 5 can be slid to the side of the connecting beam 1 near the end plate 2 to install the lower whole piece of suspended formwork.

[0031] The lower surface of the bottom plate 51 is provided with a connecting vertical plate 52 for hanging the hoisting device 6. Considering the heavy weight of the formwork, in order to increase the stability of the device, the connecting vertical plate 52 is provided with two plates, each of which is vertically fixed on the lower surface of the bottom plate 51 by welding, and each of which is provided with a hole for hanging the hoisting device 6, and the hoisting device 6 is hung on the connecting vertical plate 52 through the two holes. The hoisting device 6 can be a hand-operated hoist or an electric hoist, which is used for lifting the suspended formwork below. In order to prevent the connecting vertical plate 52 from being damaged due to the excessive load caused by the shaking of the formwork during lifting of the hoisting device 6, a set of stiffened plate assemblies 53 is arranged on the outer side of each of the two connecting vertical plates 52, which is used for improving the carrying capacity of the connecting vertical plate 52, improving the bending and shearing carrying capacity of the lifting structure, and enhancing the structural stiffness and stability. Each set of stiffened plate assemblies 53 includes a plurality of stiffened plates, and two stiffened plates are arranged in the embodiment. The top of the stiffened plate assembly 53 is fixedly connected with the lower surface of the bottom plate 51, and the side edge is fixedly connected with the connecting vertical plate 52, which is generally fixed by welding.

[0032] The above-described embodiments are only a preferred scheme of the present application, and are not intended to limit the present application. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application. Therefore, any technical scheme obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present application.
