Description
Technical Field
[0001] This utility model relates to the field of hole formwork construction technology in building engineering, and in particular to a new type of economical and efficient hole formwork device. Background Technology
[0002] With the rapid development of my country's engineering technology and the accelerated pace of urbanization, suspended formwork construction technology for building foundation pits is becoming increasingly common. In this process, selecting a suitable suspended formwork device not only improves the efficiency of pit construction but also affects the overall construction quality of the building. Therefore, exploring more advantageous suspended formwork devices based on the shortcomings of current devices is of great importance and significance for the construction of pits in modern buildings. This utility model is a suspended formwork device for pit construction, which can be used in various situations and solves the problems of easy detachment and low reusability of current suspended formwork devices. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a new type of suspended formwork device for hole construction.
[0004] This utility model is achieved through the following technical solution:
[0005] A novel suspended formwork device for hole construction includes a base plate and a connecting screw. A threaded hole matching the connecting screw is opened in the center of the base plate. The lower part of the connecting screw is threaded to the base plate. A fixing nut and a U-shaped clamp are threaded to the connecting screw on the top and bottom of the base plate, respectively. A balance nut plate is threaded to the upper part of the connecting screw.
[0006] The base plate is a circular wooden board with a diameter of 50cm and a thickness of 1.5cm.
[0007] The connecting screw is a steel screw, 80cm in length and 1.2cm in diameter.
[0008] The fixing nut has an inner diameter of 1.2cm and a height of 1.5cm.
[0009] The aforementioned balance nut is a mountain-shaped nut.
[0010] The advantages of this utility model are: the base plate is circular, which matches the shape of the hole, making it highly practical; a mountain-shaped clip is provided under the base plate, eliminating the need for a separate shaping bracket, making it simple and easy to operate; a connecting screw is used to connect to the base plate, and the thread height is adjustable to meet the needs of holes of different sizes; this utility model can be applied in the construction process of hole templates, making construction convenient, installation simple, economical and efficient. Attached Figure Description
[0011] Figure 1 This is a structural diagram of the base plate of this utility model;
[0012] Figure 2 This is a schematic diagram of the structure of this utility model. Detailed Implementation
[0013] like Figure 1 , 2 As shown, a novel suspended formwork device for hole construction includes a base plate 1 and a connecting screw 2. A threaded hole matching the connecting screw 2 is formed in the center of the base plate 1. The lower part of the connecting screw 2 is threaded onto the base plate 1. A fixing nut 4 and a U-shaped clip 3 are threaded onto the connecting screw 2, located respectively above and below the base plate 1. A balance nut plate 5 is threaded onto the upper part of the connecting screw 2. The balance nut plate 5 is a U-shaped nut.
[0014] This utility model relates to a base plate 1, made of round wood, 50 cm in diameter and 1.5 cm thick, primarily used to seal the bottom of the opening; a connecting screw 2, made of steel, 80 cm long and 1.2 cm in diameter, primarily used to connect the base plate 1; a mountain-shaped clip 3, model M12, made of iron, used to fix the bottom surfaces of the base plate 1 and the connecting screw 2; a fixing nut 4, made of steel, with an internal diameter of 1.2 cm and a height of 1.5 cm, primarily used to fix the top of the connection between the base plate 1 and the connecting screw 2; and a balance nut piece 5, made of steel, primarily used to connect the screw 2 and fix the mold at the axial position of the hole. This utility model is an economical and efficient hole-lifting mold device, and its specific usage process is as follows:
[0015] Step 1: Assemble the mold and screw the fixing nut 4 into the connecting screw 2;
[0016] Step 2: Insert the end of the connecting screw 2 with the fixing nut 4 into the threaded hole of the base plate 1;
[0017] Step 3: Use the mountain-shaped clip 3 to screw the base plate into the connecting screw 2, and use the fixing nut 4 to lock the base plate 1 in place;
[0018] Step 4: After the floor slab is poured, insert the connecting bolt 2 into the hole;
[0019] Step 5: Screw the balance nut piece 5 into the connecting screw 2 along the top of the connecting screw 2 until both ends of the balance nut piece 5 are stuck at the edge of the hole;
[0020] Step 6: After slightly adjusting the position of the locking point, tighten the balance nut piece 5 and then pour the hole.
