Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a building construction hoisting formwork device. Background Technology

[0002] In construction, suspended formwork refers to formwork that hangs in the air without any underlying support. Specifically, it is used when pouring concrete because there is no supporting structure underneath, the floor height is too high, the volume of concrete being poured is small, and the cost of supporting structures is too high. Suspended formwork can be fixed in various ways, such as using water-stop tie rods. Suspended formwork construction is widely used in various civil engineering projects, such as the foundation of large equipment and the pouring of valve wells.

[0003] Currently, most existing construction formwork is a fixed structure and cannot be adjusted according to the actual size of the building and the formwork. Different types of formwork require different models of formwork devices for different construction methods. According to the patent with publication number CN222253102U, which describes a formwork device for building construction, although the size of the formwork device can be adjusted according to the actual use, the screw connection and meshing structure of the device are too complicated. In actual use, it is easy to be damaged and difficult to operate synchronously and in a coordinated manner, so its practicality is relatively low.

[0004] To address the aforementioned problems, this utility model provides a construction formwork hoisting device to solve the problems existing in the prior art. Utility Model Content

Detailed Implementation

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] Figures 1-3The diagram shown is a complete structural schematic of a construction formwork hoisting device according to this utility model. Please refer to [link / reference]. Figures 1-3 This embodiment of a building construction formwork hoisting device includes a first main board 100, a second main board 110 cooperating with one side of the first main board 100, a limiting slot 1001 on the side of the first main board 100 facing the second main board 110, a limiting pull plate 120 slidably matched with the limiting slot 1001 on one side of the second main board 110, auxiliary top plates 200 horizontally sliding on both sides of the upper end of the first main board 100 and the second main board 110 respectively, and a guide adjustment groove 210 on the opposite side of the two auxiliary top plates 200, and a guide positioning plate 130 slidably matched with the guide adjustment groove 210 on the upper end of the first main board 100 and the second main board 110, and a locking structure is provided between the limiting slot 1001 and the limiting pull plate 120, and between the auxiliary top plate 200 and the guide positioning plate 130.

[0022] The upper part of the limiting pull plate 120 along its extension direction has several evenly distributed positioning holes 1201. A first nut 300 is fixed at the extension opening of the limiting slot 1001 on the central axis of the first main plate 100. A first locking bolt 310 is vertically threaded onto the inner side of the first nut 300, and the lower end of the first locking bolt 310 is inserted into the positioning holes 1201. It can be understood that the cooperation of the limiting pull plate 120 and the limiting slot 1001 allows for the extension, stretching, and shortening of the originally parallel first main plate 100 and second main plate 110. The cooperation of the positioning holes 1201, the first nut 300, and the first locking bolt 310 allows for the locking and positioning of the extension stroke between the limiting pull plate 120 and the limiting slot 1001. This design is suitable for building structures and concrete formwork of different lengths. A central rib 140 is fixed at the top centerline of the first main plate 100 and the second main plate 110, and the guide positioning plate 130 is fixedly connected to the central rib 140 in a cross shape. The central rib 140, the guide positioning plate 130, and the auxiliary top plate 200 are flush with each other. This design allows the formwork lifting device to support the bottom of the template with a relatively flat surface, ensuring the quality of the formwork lifting. The guide positioning plate 130 has limiting slides 1301 on both sides along its length direction, and the inner side of the guide adjustment groove 210 has a straight slide groove 2101 that matches the limiting slides 1301. The upper part of the end of the guide positioning plate 130 has an avoidance groove 1302, and a second nut 400 is fixed to the bottom of the inner side of the avoidance groove 1302. A second locking bolt 410 is vertically threaded to the inner side of the second nut 400, and the lower end of the second locking bolt 410 abuts against the bottom of the inner side of the guide adjustment groove 210. The auxiliary top plate 200, after stretching and adjustment, can be locked and secured by the cooperation of the second nut 400 and the second locking bolt 410, while the provided clearance groove 1302 can prevent the upper part of the second locking bolt 410 from protruding from the top of the device. Specifically, in this embodiment, the first main plate 100 and the second main plate 110, which were originally short-connected, can be stretched and expanded by the cooperation of the limiting pull plate 120, the limiting slot 1001 and the locking member, so as to adapt to the support of building bodies and bottom molds of different length specifications. The auxiliary top plate 200 used to support the bottom mold on the upper part of the first main plate 100 and the second main plate 110 can be stretched and adjusted across by the cooperation of the limiting slide bar 130, the guide adjustment groove 210 and the locking member. This effectively solves the inconvenience and increased cost caused by the inability to adjust the size of the existing formwork device. At the same time, the technical structure is simple, easy to maintain, and convenient to operate, and its practicality is further improved.

[0023] Furthermore, the outer periphery of the first main board 100 and the second main board 110 also has multiple fixing ears 500, and a lifting hole 5001 is provided in the center of each fixing ear 500. It can be understood that in the actual use of the suspended formwork, the device can be supported and stabilized by either the water-stop tie rod or by the sling and the fixing ears 500. The specific shape and position of the hanging parts can be set according to the actual situation, which will not be described in detail here.

[0024] In summary, the construction formwork hoisting device of this embodiment, when in use, can stretch and expand the originally short-connected first main plate 100 and second main plate 110 through the cooperation of the limiting pull plate 120, the limiting slot 1001 and the locking device, thereby adapting to the support of building bodies and bottom formwork of different lengths. Through the cooperation of the limiting slide bar 130, the guide adjustment groove 210 and the locking device, the auxiliary top plate 200 on the upper part of the first main plate 100 and the second main plate 110 used to support the bottom formwork can be stretched and adjusted across, effectively solving the inconvenience and increased cost caused by the inability to adjust the size of existing formwork hoisting devices. At the same time, it is simple in structure, easy to maintain and convenient to operate.
