[0001] The invention belongs to the field of construction, and in particular relates to a wall panel outer leaf and wall panel inner leaf tie piece of a cast-in-place wall panel. Background Art

[0002] Buildings assembled on site from prefabricated parts and components are called prefabricated buildings. Building houses through prefabricated buildings can be manufactured in batches and sets, just like machine production. Just transport the prefabricated house components to the construction site and assemble them. Among them, the building wall is an important component in prefabricated buildings. The building wall includes the outer leaf of the wall panel and the inner leaf of the wall panel. The outer leaf of the wall panel and the inner leaf of the wall panel are connected with an insulation board. Since the conventional prefabricated wall panel inner and outer leaves are generally connected by stainless steel or FRP, the traditional building exterior walls generally use plastic expansion screws to fix the insulation board. According to the actual application of existing buildings, its safety risks and fire risks are still very common. For this reason, the applicant has applied for a component for fixing and connecting the inner and outer leaves of the building exterior wall insulation board. Although this component solves the above problems and effectively reduces the risk of the insulation board falling off and the fire risk, this connection component is still relatively inconvenient when connecting. It has many parts, low installation efficiency, and high construction production costs. Summary of the Invention

[0003] In order to solve one or more of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a wall panel outer leaf and wall panel inner leaf tie member for a cast-in-place wall panel. The tie member has a simple structure and can quickly and conveniently position the inner and outer leaves of the wall panel and the insulation board between the inner and outer leaves. The positioning is firm and the cost is low.

[0004] To achieve the above-mentioned purpose, the present invention provides a wall panel outer leaf and wall panel inner leaf tie parts of a cast-in-place wall panel, which is used to fix the insulation board between the wall panel outer leaf and the wall panel inner leaf, including a connecting rod, a clamping plate is fixed in the middle of the connecting rod, and a plurality of wing plates are fixed at the front of the connecting rod, wherein at least two wing plates are provided with clamping half-slot holes, and a plurality of plug-in pile heads are fixed on the back of the clamping plate. The tail of the connecting rod is provided with a fixed section, and a compression plate is installed on the fixed section.

[0005] Furthermore, the fixing section is a plurality of fine-threaded clamping cone sections arranged in a straight line.

[0006] Furthermore, the number of the wing plates is 4, which are evenly arranged in a ring shape on the connecting rod, and the wing plates are provided with weight-reducing holes.

[0007] Furthermore, the front end of the connecting rod also has a cone cap portion.

[0008] Furthermore, a reinforcement plate is fixed between the wing panels, and the reinforcement plate is located at the front of the wing panels.

[0009] Furthermore, the rear end of the fixed section is connected to a tapered rod, and the outer side of the tapered rod is provided with a plurality of coarse-toothed clamping tapered sections arranged in a straight line.

[0010] Furthermore, the connecting rod is a hollow rod, and a metal support rod is movably inserted into the hollow rod.

[0011] Furthermore, the connecting rod is made of plastic or resin.

[0012] Furthermore, a steel bar is inserted into the weight-reducing hole on one pair of wing plates.

[0013] The beneficial effects of the present invention are:

[0014] First, the tie piece not only fixes the insulation board and wire mesh, but also acts as a support rod during concrete pouring, ensuring the thickness of the wall panel. The tapered portion of the connector can control the thickness of the outer leaf, and after the wall panel is completed, it plays a role in tying the inner and outer leaves of the wall panel.

[0015] Second, a plurality of plug-in pile heads are fixed on the back of the clamping plate. The plug-in pile heads can adopt various structural forms, such as conical, flat cone, cylindrical, etc. The pile heads are conducive to preventing the connector from rotating after being combined with the insulation board, ensuring that the tie piece is stable and reliable;

[0016] Third, a number of coarse-toothed taper sections are provided on the tapered rod, which can effectively engage with the concrete after pouring, with a strong engagement force, making the anchor more firmly positioned in the wall panel;

[0017] Fourth, if the connecting rod is a hollow rod, a metal support rod can be inserted into the hollow rod to serve as a support rod. After the wall panel is prepared, the metal support rod can be pulled out and then used repeatedly, which can effectively save the cost of wall panel production.

[0018] Fifth, a reinforcement plate is designed on the wing plate to enhance the anchoring force with the concrete and the strength of the wing plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be further described below with reference to the accompanying drawings and examples:

[0025] See also Figures 1 to 4 The present invention discloses a tie member for the outer leaf and inner leaf of a cast-in-place wall panel, which is used to fix an insulation board between the outer leaf and the inner leaf of the wall panel, including a connecting rod 1, a clamping plate 2 is fixed to the middle part of the connecting rod 1, a plurality of wing plates 3 are fixed to the front part of the connecting rod 1, at least two of the wing plates 3 are provided with clamping half-slot holes 4, a plurality of plug-in pile heads 5 are fixed to the back of the clamping plate 2, a fixing section 7 is provided at the tail end of the connecting rod 1, and a compression plate 7 is connected to the fixing section 7.

[0026] The process of using the present invention is as follows: before making the wall panel, first pass the connecting rod 1 through the grid on the wire mesh frame 8, so that the snap-in half-slot hole 4 on the wing plate 3 on the connecting rod 1 is snapped onto the steel rod of the wire mesh frame 8, so that the connecting rod 1 is preliminarily positioned, and the number of the tie pieces is arranged according to the area of ​​the wall panel. After the tie pieces are arranged, the connecting rod 1 at the tail of the tie piece is passed through and fixed to the insulation board 9. Since a fixed section 7 is also fixed at the tail of the connecting rod 1, the separate pressing plate is passed through the fixed section 7 and pressed onto the insulation board 9. When the wire mesh frame 8, the tie piece and the insulation board are 9 After the connection is completed, set up the vertical formwork 10 of the wall panel, and erect the wire mesh frame 8 and the insulation board 9 between the two vertical formworks 10, and fix the steel mesh 11 between the two vertical formworks 10. The steel mesh 11 is specifically located at the tail end of the connecting rod 1. Finally, concrete is poured on both sides of the insulation board 9 respectively, and the vertical formwork 10 is dismantled after the concrete solidifies. In addition, a plurality of plug-in pile heads 5 are fixed on the back of the clamping plate 2. The plug-in pile heads 5 can adopt various structural forms, such as conical, flat cone, cylindrical, etc. The pile head is conducive to the connection piece and the insulation board 9 not rotating after being combined, ensuring that the tie piece is stable and reliable.

[0027] Furthermore, the fixing section 7 is a plurality of fine-threaded clamping cone sections 12 arranged in a straight line. Specifically, the fixing section 7 of the present invention is a plurality of fine-threaded clamping cone sections 12 arranged in a straight line. Specifically, the clamping cone section is provided with a plurality of clamping cones, so the pressing plate 7 can smoothly move toward the side of the clamping plate 2, but it is difficult to move in the opposite direction.

[0028] Furthermore, the number of the wing plates 3 is four, evenly arranged in a ring on the connecting rod 1, and the wing plates 3 are provided with weight-reducing holes 13. Specifically, in order to make the wing plates 3 more secure when they are attached to the wire mesh frame 8, the number of the wing plates 3 is four, just enough to evenly attach the steel wires around the mesh, making it more secure. In addition, the weight-reducing holes 13 provided on the wing plates 3 can effectively save material for the wing plates 3 and reduce costs. At the same time, it is conducive to the smooth discharge of air during concrete pouring and can effectively increase the bite force between the wing plates 3 and the concrete.

[0029] Furthermore, the front end of the connecting rod 1 is also provided with a conical cap portion 14. The present invention sets a conical cap portion 14 at the front end of the connecting rod 1. Since the area of ​​the top of the conical cap portion 14 is relatively small, the conical cap portion 14 can effectively reduce the contact area between the concrete and the conical cap portion 14, so that the wall panel is more beautiful and has better integrity when it is finished after production. If the conical cap portion 14 is not set and the flat head of the connecting rod 1 is directly used, the contact surface will be relatively large, and the outer surface of the wall panel will be flawed after casting.

[0030] Furthermore, a reinforcement plate 15 is fixed between the wing panels 3, and the reinforcement plate 15 is located at the front of the wing panels 3. By fixing a reinforcement plate 15 between the wing panels 3, the provision of the reinforcement plate 15 can effectively increase the connection strength of the wing panels 3, making the wing panels 3 more secure when being clamped on the wire mesh frame 8.

[0031] Furthermore, the rear end of the fixing section is connected to a tapered rod 16, and a plurality of coarse-threaded engaging tapered sections 17 are disposed on the outer side of the tapered rod 16 in a straight line. The present invention also connects a tapered rod 16 to the rear end of the fixing section. The tapered rod 16 is generally conical and is provided with a plurality of coarse-threaded engaging tapered sections 17. After concrete pouring, the tapered rod 16 can effectively engage with the concrete with a strong engagement force, making the anchor more firmly positioned in the wall panel. Of course, the tapered rod can also adopt square, rectangular, plum blossom, and other shapes.

[0032] Furthermore, the connecting rod 1 is a hollow rod 18, and a metal support rod 19 is movably inserted into the hollow rod 18. Specifically, the connecting rod 1 of the present invention can be a solid rod or a hollow rod 18. When a solid rod is used, more materials are consumed. Figure 1As shown, the tapered rod 16 is relatively long, and the tapered section is used to play the role of a support rod, so that the positioning of the vertical mold on the right side of the wall panel is more accurate, ensuring the thickness of the wall panel. If a hollow rod 18 is used, the length of the tapered rod 16 can be saved a lot. It is only necessary to insert a metal support rod 19 into the hollow rod 18 to play the role of a support rod. When the wall panel is prepared, the metal support rod 19 can be pulled out and then used repeatedly, which can effectively save the cost of wall panel production.

[0033] Furthermore, the connecting rod is made of plastic or resin. Specifically, the connecting rod of the present invention is made of plastic or resin, which has the characteristics of good ductility and low cost. Of course, the connecting rod can also be made of metal or a combination of metal and non-metal materials.

[0034] Furthermore, a steel bar 20 is connected to the lightening hole on one of the wing panels. To further increase the tensile strength between the inner and outer leaves of the wall panel, the present invention also inserts a steel bar 20 into the lightening hole on one of the wing panels. A stop plate can be provided at one end of the steel bar 20. Through the action of the stop plate, the steel bar 20 can further engage with the outer leaf of the wall panel, thereby strengthening the engagement force between the outer and inner leaves of the wall panel.

[0035] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art through logical analysis, reasoning, or limited experimentation based on the concepts of the present invention and the prior art should be within the scope of protection defined by the claims.
