Description

Technical Field

[0001] This utility model relates to the field of precast component technology, and in particular to a steel cage mold hanger for precast concrete components. Background Technology

[0002] Precast concrete components are widely used in bridge construction, building construction, and other fields. To accelerate production and reduce costs, the factory has shifted from ordering molds of different specifications to using rebar cages that are directly placed in adjustable molds for concrete pouring. The fabrication of these rebar cages requires molds to expedite the process. They can typically be fabricated on-site in the factory area. However, because the rebar cages contain a large number of bundled steel bars, their weight can range from several tons to tens of tons depending on the construction area, making them inconvenient to move. Therefore, scaffolding is used for hoisting.

[0003] The existing hoisting system in the factory used a connecting frame. In order to strengthen it, a triangular frame was used for stability. However, when hoisting the steel cage mold, it was found that this type of hoisting system had a long production time and a heavy overall weight due to the welding of many triangular support plates, and its performance was also very average. Therefore, the applicant decided to make a simple steel cage mold hoisting system. Utility Model Content

[0004] The purpose of this utility model is to provide a steel cage mold hanger for precast concrete components to solve the problems encountered in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A rebar cage mold hanger for precast concrete components includes a top pipe, a bottom pipe, and a positioning assembly. The top pipe has at least two sections, each with its two sides fixedly connected to the top of the bottom pipe via a first fixing member. The bottom pipe has at least four sections, each with its top fixedly connected to the top pipe via a second fixing member. Both ends of each bottom pipe are fixedly connected to the positioning assembly. The positioning assembly includes a connecting seat and a connecting member. One side of the connecting seat is fixed to the end of the bottom pipe, and the bottom of the connecting seat is inserted into the connecting member and fixed with screws. The connecting member is fixed to both sides of the top of the rebar cage mold.

[0007] In the above scheme, hanging plates are fixed on both sides of the top of the jacking pipe, and the hanging plates are rectangular plate structures. Furthermore, as a preferred embodiment, the hanging plates are provided with several lifting holes.

[0008] In the above scheme, the top pipe and the bottom pipe are respectively assembled and welded by two channel steels, and the ends of the top pipe and the bottom pipe are respectively fixed with baffles.

[0009] In the above scheme, the first and second fixing components have the same structure, and the first fixing component is fixedly connected to the second fixing component by bolts. The second fixing component includes a base plate, which is fixedly installed on the top of the bottom tube, and the two sides of the base plate are fixedly connected to the two sides of the bottom tube by reinforcing ribs.

[0010] In the above scheme, the connector includes a base and a plug. The base is fixed at both ends of each bottom tube and is integrally connected with the plug. The plug has a first connecting groove inside. The top of the connector has a slot that mates with the plug, and the connector has a second connecting groove that is coaxially arranged with the first connecting groove inside.

[0011] To ensure more accurate positioning after connection, the plug has pointed ends on both sides and a beveled end on the back.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This rebar cage mold hanger has a simple structure. It only requires fixing the top pipe and bottom pipe in the horizontal and vertical directions, and then hoisting the rebar cage mold through the connection of the positioning components. The manufacturing process is simple. The hollow structure of the top pipe and bottom pipe spliced ​​with channel steel makes the overall weight of the hanger light. The hoisting method of using screws through the positioning components has high stability and is suitable for heavy lifting work, especially the hoisting of rebar cage molds and subsequent hoisting of precast concrete components.

These drawings are simplified schematic diagrams, illustrating only the basic structure of this utility model, and therefore only show the relevant components of this utility model.

[0022] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0023] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1 , Figure 2 , Figure 4 As shown, a steel cage mold hanger for a precast concrete component includes a top pipe 1, a bottom pipe 2, and a positioning component 3, wherein the top pipe 1 and the bottom pipe 2 are fixedly connected in the horizontal and vertical directions.

[0025] There are at least two jacking pipes 1. The two sides of each jacking pipe 1 are connected to the bottom pipe 2 by a first fixing member 11. The top of the bottom pipe 2 is fixed to the jacking pipe 1 by bolts. There are at least four bottom pipes 2. The top of each bottom pipe 2 is connected to the jacking pipe 1 by a second fixing member 21. The jacking pipe 1 is fixed to the bottom pipe 2 by bolts. The two ends of each bottom pipe 2 are welded and fixedly connected to the positioning assembly 3.

[0026] Please refer to the following when making it. Figure 3 The jacking pipe 1 and the bottom pipe 2 are assembled and welded from two channel steels. The grooves of the two channel steels are joined together with opposite sides, and then the structure is fixed. Finally, the joint is welded firmly. Baffles 14 are fixed at the ends of the jacking pipe 1 and the bottom pipe 2, which seal both ends of the jacking pipe 1 and the bottom pipe 2. The sealing of the ends of the bottom pipe 2 facilitates the fixing of the positioning component 3.

[0027] To facilitate hoisting, hanging plates 12 are welded and fixed to both sides of the top of the jacking pipe 1. The hanging plates 12 are rectangular plate structures, fixed in the middle of the top of the jacking pipe 1 along its extension direction, which is the connection point of the two channel steel pieces. Furthermore, as a preferred option, the hanging plates 12 are provided with several hoisting holes 13, allowing for the selection of appropriate hoisting holes 13 for hoisting different specifications and lengths of rebar cage molds. The hoisting is primarily achieved by a crane driving an electric hoist, whose hook pulls a wire rope. The wire rope passes through the hoisting holes 13 for lifting. One end of the wire rope is fixed to one side of the hanging plate 12, the other end is fixed to the other side of the hanging plate 12, and the middle is suspended in the hook.

[0028] Continue reading Figure 3 To facilitate manufacturing, the first fixing member 11 and the second fixing member 21 have identical structures. The first fixing member 11 is fixedly connected to the second fixing member 21 by bolts. The second fixing member 21 includes a base plate, which is fixedly installed on the top of the bottom pipe 2. The two sides of the base plate are welded to the two sides of the bottom pipe 2 via stiffening ribs. Because the first fixing member 11 and the second fixing member 21 have identical structures, the first fixing member 11 also has a base plate, which is fixedly installed on the top of the jacking pipe 1. The two sides of this base plate are welded to the two sides of the jacking pipe 1 via stiffening ribs. The base plate at the bottom of the jacking pipe 1 and the base plate at the top of the bottom pipe 2 are fixed together by bolts, thereby increasing the contact area at the connection and ensuring a secure fixation.

[0029] Please see Figure 3 , Figure 5 and Figure 6 The positioning component 3 includes a connecting seat 31 and a connecting piece 32. One side of the connecting seat 31 is welded and fixed to the end of the bottom tube 2. The bottom of the connecting seat 31 is inserted into the connecting piece 32 and fixed with screws. The connecting piece 32 is fixed to the top two sides of the rebar cage mold. The connecting seat 31 and the connecting piece 32 are in a separate state when not being hoisted. The connecting seat 31 is located in the hanger, while the connecting piece 32 is located on the top of the rebar cage mold. During installation, the connecting seat 31 and the connecting piece 32 are first fixed together with screws. Then, the hanger is placed on the top of the rebar cage mold using an electric hoist, and the connecting piece 32 is detachably positioned and fixed, such as by snapping or hooking.

[0030] In implementation, for positioning purposes, the connector 31 includes a base 33 and a plug 34. The base 33 is welded and fixed to both ends of each bottom tube 2, and the base 33 and plug 34 are integrally connected. The plug 34 has a first connecting groove 35 inside. The top of the connector 32 has a slot 36 that mates with the plug 34, and the inside of the connector 32 has a second connecting groove 37 that is coaxially arranged with the first connecting groove 35. The two can be fixed together by passing a screw through the first connecting groove 35 and the second connecting groove 37.

[0031] In order to make the positioning more accurate after the two are connected, the two sides of the plug 34 are pointed structures and the rear side of the plug 34 is a beveled structure. In order to make the connector 3 fit, the side of the slot 36 is a V-shaped structure and the rear side is also a beveled structure.

[0032] In summary, this rebar cage formwork lifting frame has a simple structure. It only requires fixing the top pipe 1 and bottom pipe 2 in the horizontal and vertical directions, and then lifting the rebar cage formwork through the connection of the positioning components 3. The manufacturing process is simple; the hollow structure of the top pipe 1 and bottom pipe 2, made of spliced ​​channel steel, makes the overall weight of the lifting frame light. The lifting method using screws passing through the positioning components 3 provides high stability and is suitable for heavy-duty lifting work, especially the lifting of rebar cage formwork and subsequent precast concrete components.
