Description

Technical Field

[0001] The utility model belongs to the technical field of building formwork, and particularly relates to a steel-frame plastic C-groove. Background Art

[0002] For example, the building formwork disclosed in the patent CN219451513U developed by the applicant has pin holes on the side and end faces of adjacent formworks corresponding to each other one by one. The formworks are connected by cooperating with pins and pin plates passing through the pin holes, and the opposite formworks are connected by tie rods or tie plates to facilitate casting concrete slurry between the opposite formworks. According to the actual designed building, various types of high-strength stainless steel building formworks (including general parts and special parts) with different shapes and sizes are designed correspondingly. After connection, an inner cavity of the building to be cast as a whole can be formed, which is convenient for integral casting and forming.

[0003] For the corner position of a building, the formwork connection is achieved through an angle steel formwork part to transfer two general formwork parts perpendicular to each other. For example, the high-strength alloy angle steel and its connection structure disclosed in CN219909979U form the corner of the building after casting and removing the formwork. For the inner corner position of a building, the formwork connection is achieved through a corner formwork part (commonly known as "C-groove") to transfer two general formwork parts. For example, the cast-in-place corner high-strength alloy formwork disclosed in CN308578652S. The corner formwork has a large area, like the general formwork part. At present, the two large outer sides and the two small sides for connection of the corner formwork are integrally formed by high-strength stainless steel alloy plates. Compared with the general formwork part with a U-shaped cross-section, the number of forming and bending times is more, the manufacturing is inconvenient, and the forming size is not easy to guarantee. During on-site use, the two large outer sides are also prone to being damaged, deformed or destroyed due to abnormal impacts such as dropping and impact, affecting reuse, and there is a need for improvement and optimization in design. Summary of the Invention

[0004] Aiming at the above-mentioned deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a steel-frame plastic C-groove to avoid the problems that the current corner formwork is not convenient for manufacturing and the formwork surface is easy to be damaged, and achieve the effects of not being easily damaged and being beneficial to repeated use.

[0005] To solve the above technical problem, the utility model adopts the following technical scheme:

[0006] The steel-frame plastic C-groove includes a plurality of L-shaped inner support members arranged at intervals. The plurality of L-shaped inner support members are arranged in a row and adjacent two L-shaped inner support members are parallel and facing each other; one ends of the L-shaped inner support members are perpendicularly connected to a first side connecting plate in a plate shape together, and the other ends of the L-shaped inner support members are perpendicularly connected to a second side connecting plate in a plate shape together; a plurality of pin holes are respectively arranged at intervals along the arrangement direction of the L-shaped inner support members on the first and second side connecting plates;

[0007] On one side of each L-shaped inner support member that forms an external corner, there is a main body panel with an L-shaped cross-section connected. The main body panel covers the two outer side surfaces of each L-shaped inner support member that form the external corner; the two side edges of the main body panel corresponding to the two ends of the L-shaped inner support member are flush with the outer side surfaces of the first and second side connection plates respectively.

[0008] To further improve the above technical solution, the main body panel is made of plastic material and is adhesively connected to the two outer side surfaces of all or part of the L-shaped inner support members that form the external corner.

[0009] Optionally, the main body panel is made of plastic material and is connected to the two outer side surfaces of all or part of the L-shaped inner support members that form the external corner by corresponding screws passing through the main body panel.

[0010] Furthermore, each L-shaped inner support member, the first side connection plate, and the second side connection plate are made of metal material, and the connection parts are all fixedly connected by welding.

[0011] Furthermore, the pin holes on the first and second side connection plates correspond one by one in the direction of arrangement of each L-shaped inner support member. On the inner side surfaces of the first and second side connection plates, several reinforcing gaskets are respectively connected, and through holes coaxial and equal in diameter with the corresponding pin holes are provided on the reinforcing gaskets.

[0012] Furthermore, the reinforcing gaskets on the inner side surfaces of the first and second side connection plates are alternately staggered in the direction of arrangement of each L-shaped inner support member.

[0013] Furthermore, the reinforcing gaskets are made of metal material and are fixedly connected by welding to the inner side surface of the corresponding first side connection plate or second side connection plate.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The steel frame plastic C-groove of the utility model is convenient to manufacture.

[0022] The following further describes in detail the specific embodiments of the present invention with reference to the accompanying drawings.

[0023] Please refer to Figures 1-5 , the steel frame plastic C-channel of the specific embodiment includes a plurality of L-shaped inner support members 5 arranged at intervals, and the plurality of L-shaped inner support members 5 are arranged in a row and adjacent two L-shaped inner support members 5 are parallel and facing each other; one end of each L-shaped inner support member 5 is commonly perpendicular to the connecting plate-shaped first side connecting plate 1, and the other end of each L-shaped inner support member 5 is commonly perpendicular to the connecting plate-shaped second side connecting plate 2; the first and second side connecting plates extend along the length direction in which the L-shaped inner support members 5 are arranged at intervals, and a plurality of pin holes 3 are respectively arranged at intervals along the arrangement direction of the L-shaped inner support members 5 on the first and second side connecting plates; a main body panel 6 with an L-shaped cross section corresponding to the external angle is connected to the side of each L-shaped inner support member 5 forming the external angle, and the main body panel 6 covers the two outer side surfaces of each L-shaped inner support member 5 forming the external angle; the two side edges of the main body panel 6 corresponding to the two ends of the L-shaped inner support member 5 are respectively flush with the outer side surfaces of the first and second side connecting plates.

[0024] The main body panel 6 is made of a plastic material, which is hard, such as polyphenylene sulfide, polyethylene, polyamide, etc., and the thickness is preferably 10-15 mm. It can be integrally injection-molded into an integral part with an L-shaped cross section, or it can be two plastic plate members that are respectively perpendicular to each other and cover the two outer side surfaces of the L-shaped inner support member 5 forming the external angle. Each L-shaped inner support member 5, the first side connecting plate 1, and the second side connecting plate 2 are made of a weldable metal material, and the connecting parts are all fixedly connected by welding.

[0025] The steel frame plastic C groove of the embodiment adopts a high-strength alloy frame + plastic-coated structure, which can also be called: high-strength plastic-coated corner template structure! It is easy to manufacture. The L-shaped inner support 5 can be made of pipes or angle steel, and the end is inverted at 45° and welded to form an L-shaped inner support 5. The first and second side connecting plates are common parts. They can be made of 3-5mm thick steel plates. They are laser cut or sheared into long strips. Each L-shaped inner support 5 and the first and second side connecting plates are placed in a welding mold for shaping. After welding, the basic frame is formed, and then the main panel 6 is connected to the outer side of the positive angle of each L-shaped inner support 5. The main panel 6 with the largest area in contact with the concrete slurry (can be coated with a release agent) is made of plastic material. During use, it is not easy to be damaged, deformed or destroyed due to abnormal impacts such as falling and impact, and is easy to reuse.

[0026] The connection between the main panel 6 and the L-shaped inner support 5 can be achieved by bonding the two outer side surfaces that form the positive angle with all or part of the L-shaped inner support 5; or by corresponding screws (not shown in the figure) passing through the main panel 6 and connecting the two outer side surfaces that form the positive angle with all or part of the L-shaped inner support 5. When screws are used, the main panel 6 should have a recessed groove that matches the screw head to accommodate the screw head and prevent the screw head from protruding from the main panel 6. When the main panel 6 is connected to some of the L-shaped inner support 5, it should include at least the two outermost L-shaped inner support 5. After installation, the main panel 6 and the two outer side surfaces that form the positive angle with each L-shaped inner support 5 are in contact with each other.

[0027] Please continue to see Figure 1 , Figure 2 and Figure 4 , wherein the pin holes 3 on the first and second side connecting plates correspond to each other in the direction in which the L-shaped inner supporting members 5 are arranged, and a plurality of reinforcing gaskets 7 are connected to the inner side surfaces of the first and second side connecting plates, respectively, and a through hole coaxial with the corresponding pin hole 3 and having the same diameter is opened on the reinforcing gasket 7. In this way, when the universal template is transferred through the pins and pin pieces, the strength of the connection position is better.

[0028] Since not all pin holes 3 need to be provided with pin-pin piece transfer, the reinforcing washers 7 on the inner side surfaces of the first and second side connecting plates are alternately staggered in the direction in which the L-shaped inner supporting members 5 are arranged. In this way, the weight can be reduced and the manufacturing difficulty can be reduced on the basis of improving the connection strength. When connecting, the position with the reinforcing washers 7 can be selected for the connection of the pin-pin piece.

[0029] The reinforcing gasket 7 is also made of weldable metal material, preferably an iron sheet with a thickness of 2-3 mm, and is welded and fixedly connected to the inner side surface of the corresponding first side connecting plate 1 or the second side connecting plate 2, and is implemented simultaneously when welding to form the basic frame.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
