Description

Technical Field

[0001] The utility model relates to the field of building accessories, in particular to an assembled composite plate with a detachable aluminum formwork structure. Background Art

[0002] The currently common prefabricated composite slabs require, during the construction process, to set up supports under the prefabricated composite slabs to be laid, and then hoist the prefabricated composite slabs to the designated position so that the extended steel bars of the prefabricated composite slabs extend to the beam structure; then lay the formwork under the nodes of the prefabricated composite slabs and the beam structure, and finally cast the beam-slab nodes and the prefabricated composite slabs in situ, and finally remove the formwork and supports.

[0003] Since the supports will need to be removed later, the formwork will also need to be dismantled piece by piece. While support removal is relatively easy, the formwork is located at the top of the floor, and dismantling each piece individually increases the workload. Although Fujian Construction Engineering Prefabricated Building Research Institute Co., Ltd. has developed a technology for prefabricated composite panels that requires no supports or formwork, this technology has not yet been fully implemented. Currently, the construction of most prefabricated composite panels still requires supports and formwork. Utility Model Content

[0004] The purpose of the utility model is to provide an assembled composite plate with a detachable aluminum formwork structure, which realizes the quick assembly and disassembly of the formwork and improves the construction efficiency.

[0005] The utility model is realized by the following technical solution: an assembled composite panel with a detachable aluminum mold structure, the main body of which is an assembled composite panel, the left and right sides of the assembled composite panel are provided with outwardly extending extension steel bars, and the upper surface of the assembled composite panel is provided with truss steel bars;

[0006] A group of threaded steel bars extending downwards are provided on the left and right sides of the bottom surface of the assembled composite plate, and any group of threaded steel bars is disassembled and installed with an aluminum mold structure;

[0007] The aluminum mold structure includes an L-shaped template, an L-shaped support seat, an elastic telescopic member, a double connecting rod and a tightening member; the L-shaped support seat is connected to the threaded steel bar, and the L-shaped template is located on the outside of the L-shaped support seat; the L-shaped template and the L-shaped support seat are connected by an elastic telescopic member, two double connecting rods are provided and located between the L-shaped template and the L-shaped support seat, and the two double connecting rods are respectively arranged on the front and rear sides of the L-shaped template and the L-shaped support seat; the tightening member is connected between the two double connecting rods.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] 1. An independently disassembled aluminum formwork structure is set up. The aluminum formwork structure is an integral design and can be disassembled and installed on the prefabricated composite panel. This reduces the need to install the formwork after the prefabricated composite panel is hoisted into place. In addition, the work of disassembling the formwork is also simplified, reducing the overall workload.

[0010] 2. The design of basket screws and steel ropes is adopted here, mainly considering the labor-saving operation. Since the slippage of the L-shaped template needs to be considered during demoulding, a certain friction force needs to be overcome. We drive the movement of the L-shaped template by bending the double connecting rod. In order to achieve the bending of the double connecting rod, many methods were experimented here, and finally the basket screw, a common tensioning mechanism of the pole, was used to achieve it.

[0011] 3. The purpose of the elastic expansion part is to ensure that the L-shaped formwork can fit tightly against the beam structure and to ensure that there will be no leakage after casting.

[0012] 4. The aluminum mold structure can be used repeatedly, reducing the cost of use. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, they should not be understood as limitations on the present invention.

[0020] like Figure 1-4 As shown: an assembled composite panel with a detachable aluminum formwork structure, the main body of which is an assembled composite panel 1, the left and right sides of the assembled composite panel 1 are provided with outwardly extending extension steel bars 11, and the upper surface of the assembled composite panel 1 is provided with truss steel bars 12;

[0021] A group of threaded steel bars 13 extending downwards are provided on the left and right sides of the bottom surface of the assembled composite plate 1, and an aluminum formwork structure 2 is installed on each group of threaded steel bars 13;

[0022] The aluminum mold structure 2 includes an L-shaped template 21, an L-shaped support seat 22, an elastic telescopic member 23, a double connecting rod 24 and a tightening member 25; the L-shaped support seat 22 is connected to the threaded steel bar 13, and the L-shaped template 21 is located on the outside of the L-shaped support seat 22; the L-shaped template 21 and the L-shaped support seat 22 are connected by an elastic telescopic member 23, two double connecting rods 24 are provided and are located between the L-shaped template 21 and the L-shaped support seat 22, and the two double connecting rods 24 are respectively arranged on the front and rear sides of the L-shaped template 21 and the L-shaped support seat 22; the tightening member 25 is connected between the two double connecting rods 24.

[0023] The threaded steel bars 13 here can be welded to the steel bars inside the assembled composite panel 1; or they can be connected to a steel plate, and the steel plate is welded to the steel bars inside the assembled composite panel 1. Here, a group of threaded steel bars 13 is a plurality of threaded steel bars distributed sequentially from front to back.

[0024] The L-shaped template 21 and the L-shaped support seat 22 are both composed of a horizontal aluminum alloy plate and a vertical aluminum alloy plate, wherein reinforcing ribs are provided between the horizontal aluminum alloy plate and the vertical aluminum alloy plate.

[0025] The elastic expansion member 23 is for continuously applying an outward thrust to the L-shaped template 21. The double connecting rod 24 here is a double connecting rod 24 structure that folds inward.

[0026] like Figure 4 As shown: the tightening member 25 includes a first steel rope 251, a second steel rope 252 and a basket screw 253. The first steel rope 251 and the second steel rope 252 are respectively connected to the two double connecting rods 24, and the first steel rope 251 and the second steel rope 252 are connected by the basket screw 253.

[0027] By turning the turnbuckle 253, the first and second steel ropes 251, 252 can be tightened or loosened. When the first and second steel ropes 251, 252 are tightened, they pull the two double links 24 toward each other, driving the L-shaped template 21 to overcome the elastic expansion member 23 and move toward the L-shaped support base 22.

[0028] like Figure 2 、 3 As shown, the elastic telescopic member 23 includes an outer sleeve 231, an inner rod 232, and a spring 233. The spring 233 is disposed within the outer sleeve 231, and the inner rod 232 extends into the rear opening of the outer sleeve 231 and abuts against the spring 233. The front end of the outer sleeve 231 is connected to the L-shaped template 21, and the rear end of the inner rod 232 is connected to the L-shaped support base 22. A limit structure is not required here, as the maximum extension distance of the elastic telescopic member 23 is already limited by the maximum extension limit of the double connecting rod 24.

[0029] A limiting hole is provided on the L-shaped support seat 22 , and the threaded steel bar 13 passes through the limiting hole, and the L-shaped support seat 22 is connected to the assembled composite plate 1 through the nut 132 .

[0030] The double connecting rod 24 includes two connecting rods, which are hinged to each other, and the two ends of the double connecting rod are respectively hinged to the L-shaped template 21 and the L-shaped support base 22. This is a common connecting rod mechanism, so it is no longer explained.

[0031] The specific usage of this utility model is as follows:

[0032] Since the prefabricated composite panels are standard components, which are generally prefabricated components with a length of 6 meters and a width of 3 meters, the aluminum formwork structure 2 is also set to the length required above. In the prefabrication factory, the aluminum formwork structure 2 can be pre-assembled on the prefabricated composite panels, and then hoisted onto the transport vehicle for transportation to the site.

[0033] The on-site hoisting method is no different from the existing technology. After hoisting into place, the worker turns the basket screw 253. Under the action of the elastic telescopic member 23, the L-shaped template 21 moves outward, and the folded double connecting rod is gradually unfolded. When the L-shaped template 21 fits the beam structure, the installation of the aluminum formwork structure 2 is completed.

[0034] After the concrete is poured, and after it solidifies, workers prepare liftable supports to support the double-linked rods. They then hammer the L-shaped formwork 21 to separate it from the concrete structure. Workers then turn the turnbuckles 253, forcing the double-linked rods to fold, allowing the L-shaped formwork 21 to move inward. Finally, workers unscrew the nuts 132, separating the aluminum formwork 2 from the prefabricated composite panels. The supports are adjusted to lower the aluminum formwork 2, which is then transported back to the prefabrication plant for cleaning and subsequent installation on the next batch of prefabricated composite panels, ensuring reuse.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
