Description

Technical Field

[0001] This utility model relates to the field of hanging basket mold adjustment experimental technology, and more specifically, to a continuous jack for hanging basket mold adjustment. Background Technology

[0002] Hanging baskets are the main equipment in cantilever construction, and can be divided into four types according to their structural form: truss type, cable-stayed type, steel type, and hybrid type. Based on the requirements of concrete cantilever construction technology and design drawings for hanging baskets, this paper comprehensively compares the characteristics, weight, type of steel used, and construction technology of various types of hanging baskets. The design principles for hanging baskets are: light weight, simple structure, sturdy and stable, easy to move forward and disassemble, strong reusability, small deformation under stress, and sufficient space under the basket to provide a large working surface, which is beneficial for the construction of reinforcing steel and formwork.

[0003] Currently, before the formwork adjustment of hanging baskets can be carried out, continuous tests of the continuous jacks on land are required. Only then can the formwork adjustment operation at high altitude be carried out to ensure the safety of the formwork adjustment. However, the existing continuous jacks for formwork adjustment are not conducive to demonstrating different construction scenarios during use, making it difficult to obtain more comprehensive theoretical data on the continuous jacks. Therefore, it is necessary to propose a new type of continuous jack for formwork adjustment of hanging baskets to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a continuous jack for hanging basket formwork adjustment, which aims to improve the problem that the existing continuous jacks for hanging basket formwork adjustment are not conducive to demonstrating different construction scenarios during use, thus making it difficult to obtain more comprehensive theoretical data for the continuous jacks.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a continuous jack for adjusting a hanging basket mold, including a support structure and a lifting test structure.

[0007] The supporting structure includes four support frames, reinforcing members, and pad beams. The four support frames are fixed together by the reinforcing members. A first I-beam is fixed on each of the four support frames. The first I-beam has two layers. The pad beams are fixed at intervals on the top surface of the first I-beams. An upper crossbeam is installed on the pad beams. The lifting test structure includes a base, fixing members, a steel cable hoist, and four sets of lifting components. The base is installed on the upper crossbeam by the fixing members. A continuous jack is installed on the base. The steel cable hoist is installed on the output end of the continuous jack by the reinforcing members. A lower crossbeam is sleeved on the steel cable hoist. The four sets of lifting components are placed on the lower crossbeam. The lifting components are fixed to the first I-beam.

[0008] In one embodiment of this utility model, the support frame includes two L-shaped rods, with diagonal braces fixed on the two L-shaped rods, and two connecting rods fixed between the two L-shaped rods, and the first I-beam is fixed on the connecting rods.

[0009] In one embodiment of this utility model, the reinforcing member includes a first connecting plate, a second connecting plate, and a third connecting plate. The first connecting plate is fixed on the diagonal bar, the second connecting plate is fixed at the lower end between the L-shaped bars, and the third connecting plate is fixed at the upper end between the L-shaped bars.

[0010] In one embodiment of this utility model, the fastener includes a U-shaped clamp and a nut. The U-shaped clamp is sleeved on the upper crossbeam and passes through the base, and the nut is threaded onto the U-shaped clamp.

[0011] In one embodiment of this utility model, a diagonal brace is installed between the continuous jack and the base, and four diagonal braces are symmetrically distributed. The base has a through hole that matches the U-shaped clamp, and the U-shaped clamp passes through the through hole.

[0012] In one embodiment of this utility model, the cable lifting device includes a fixed frame and a lifting frame. One end of the fixed frame is fixed with a vertical plate, the lifting frame is rotatably connected to the vertical plate, the lifting frame is sleeved on the lower crossbeam, and a dial indicator is installed at the lower crossbeam.

[0013] In one embodiment of this utility model, the connector includes a connecting seat and four steel cables. The connecting seat is installed on the upper end of the fixed frame, one end of the four steel cables is fixed to the connecting seat, and the other end of the four steel cables is fixed to the continuous jack.

[0014] In one embodiment of this utility model, the lifting component includes a pad, a self-locking jack, and a second I-beam. The pad is placed on the top surface of the lower crossbeam, the self-locking jack is placed on the pad, and a lifting pipe is placed at the output end of the self-locking jack. The second I-beam is fixed to the first I-beam, and the output end of the self-locking jack is in contact with the second I-beam.

[0015] The beneficial effects of this utility model are as follows: The continuous jack for formwork adjustment obtained through the above design allows for graded loading and extension of the lower crossbeam using four self-locking jacks at the top of the lower crossbeam. This moves the lower crossbeam downwards, and the load is transferred to the connecting seat and steel cable via a steel cable hoist, acting on the continuous jacks. A dial indicator at the lower crossbeam precisely monitors the downward displacement of the lower crossbeam as the load is added. Alternatively, two lifting components on one side can be grouped together, and different loads can be applied using self-locking jacks to simulate the unbalanced loading conditions at both ends during formwork adjustment. The lower crossbeam can also be suspended by the continuous jacks, and the downward displacement can be observed using a dial indicator while applying loads to the self-locking jacks, thus simulating the suspended condition of the formwork. This allows for simulation of various working conditions during construction on the ground, resulting in more comprehensive and accurate theoretical data for the continuous jacks. This facilitates safer and more composed construction operations and makes the jacks more convenient to use. Attached Figure Description

[0024] Example

[0025] Please see Figures 1-5 This utility model provides a technical solution: a continuous jack for adjusting a hanging basket mold, including a support structure 100 and a lifting test structure 200.

[0026] Please see Figure 1 and Figure 2 The support structure 100 includes four support frames 110, reinforcement members 120, and pad beams 140. The four support frames 110 are fixed together by the reinforcement members 120. A first I-beam 130 is fixed on the four support frames 110. The first I-beam 130 is provided with two layers. The pad beams 140 are fixed at intervals on the top surface of the first I-beam 130. An upper crossbeam 150 is installed on the pad beams 140.

[0027] The support frame 110 includes two L-shaped rods 111, with diagonal braces 112 fixed on the two L-shaped rods 111. Two connecting rods 113 are fixed between the two L-shaped rods 111, and a first I-beam 130 is fixed to the connecting rods 113. The reinforcing member 120 includes a first connecting plate 121, a second connecting plate 122, and a third connecting plate 123. The first connecting plate 121 is fixed to the diagonal brace 112, the second connecting plate 122 is fixed to the lower end between the L-shaped rods 111, and the third connecting plate 123 is fixed to the upper end between the L-shaped rods 111. The reinforcement member 120 enhances the strength and stability of the support frame 110.

[0028] Please see Figure 1 and Figures 3-5 The lifting test structure 200 includes a base 210, a fixing member 230, a steel cable hoist 240, and four sets of lifting members 270. The base 210 is installed on the upper crossbeam 150 through the fixing member 230. A continuous jack 220 is installed on the base 210. The steel cable hoist 240 is installed on the output end of the continuous jack 220 through the connecting member 250. A lower crossbeam 260 is sleeved on the steel cable hoist 240. The four sets of lifting members 270 are placed on the lower crossbeam 260 and fixed to the first I-beam 130.

[0029] The fastener 230 includes a U-shaped clamp 231 and a nut 232. The U-shaped clamp 231 is fitted onto the upper crossbeam 150 and passes through the base 210. The nut 232 is threaded onto the U-shaped clamp 231. Here, the fastener 230 facilitates the installation of the base 210 onto the upper crossbeam 150. A diagonal brace 221 is installed between the continuous jack 220 and the base 210. Four diagonal braces 221 are symmetrically distributed. The base 210 has through holes that match the U-shaped clamp 231, and the U-shaped clamp 231 passes through these through holes. Here, the diagonal brace 221 increases the stability of the continuous jack 220 during installation.

[0030] The cable lifting device 240 includes a fixed frame 241 and a lifting frame 243. A vertical plate 242 is fixed to one end of the fixed frame 241. The lifting frame 243 is rotatably connected to the vertical plate 242 and is fitted onto a lower crossbeam 260. A dial indicator is installed on the lower crossbeam 260 to accurately monitor the downward displacement of the lower crossbeam 260 when a load is added. The connector 250 includes a connecting seat 251 and four steel cables 252. The connecting seat 251 is installed on the upper end of the fixed frame 241. One end of each of the four steel cables 252 is fixed to the connecting seat 251, and the other end is fixed to a continuous jack 220. The connector 250 facilitates the connection between the cable lifting device 240 and the continuous jack 220, which has seven sets of jacks.

[0031] The lifting component 270 includes a pad 271, a self-locking jack 272, and a second I-beam 274. The pad 271 is placed on the top surface of the lower crossbeam 260, and the self-locking jack 272 is placed on the pad 271. A lifting pipe 273 is placed at the output end of the self-locking jack 272. The second I-beam 274 is fixed to the first I-beam 130, and the output end of the self-locking jack 272 is in contact with the second I-beam 274. The self-locking jack 272 can be lifted upward through the lifting pipe 273.

[0032] Specifically, the working principle of the continuous jacks for the formwork adjustment of the hanging basket is as follows: During use, the four self-locking jacks 272 on the top of the lower crossbeam 260 are used for staged loading and extension, which moves the lower crossbeam 260 downward. The lower crossbeam 260 transmits the load to the connecting seat 251 and the steel cable 252 through the steel cable sling 240, and then acts on the continuous jacks 220. At this time, the dial gauge at the lower crossbeam 260 accurately monitors the downward displacement of the lower crossbeam 260 when the load is added; alternatively, the two lifting components 270 on one side can be used as a group, thus utilizing the self-locking jacks 272... 2. Different loads are applied to simulate the unbalanced loading conditions at both ends during the formwork adjustment of the hanging basket. Alternatively, the lower crossbeam 260 can be lifted and suspended by the continuous jack 220. Then, the lower crossbeam 260 is displaced downward by the self-locking jack 272 and observed using a dial indicator, thus simulating the suspension condition of the hanging basket during formwork adjustment. In this way, various working conditions during the construction process can be simulated on the ground, thereby obtaining more comprehensive and accurate theoretical data for the continuous jack 220. This is conducive to safer and more calm construction operations in the later stages and makes it more convenient to use.

[0033] It should be noted that the specific model and specifications of the continuous jack 220 and the self-locking jack 272 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0034] The power supply and operating principle of the continuous jack 220 and the self-locking jack 272 are clear to those skilled in the art and will not be described in detail here.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
