Description

Technical Field

[0001] This utility model belongs to the technical field of concrete construction tools, and in particular relates to a combined template for simultaneous molding of concrete leveling and metal edging. Background Technology

[0002] Concrete compartmentalization refers to the practice of dividing a large concrete structure into several smaller sections (compartments) for pouring during the construction process, due to technical requirements, construction process limitations, or regulations. This practice is typically used to accommodate the concrete's setting process, control temperature stress and shrinkage deformation, and reduce the formation of cracks.

[0003] Concrete compartmentation requires the use of formwork. Formwork includes non-removable formwork and ordinary removable formwork. In the existing technology, non-removable formwork often uses angle iron as compartmentation formwork. Angle iron includes horizontal and vertical sections. The horizontal section is embedded in the concrete, and the upper end of the vertical section is exposed to the outside. In order to improve the service life of the upper end of the vertical section, a rust-proof metal edging is usually installed at the upper end of the vertical section. The commonly used material is aluminum alloy.

[0004] However, during construction, it was found that placing the non-removable formwork with metal trim directly on the base layer where compartments needed to be divided resulted in two problems. First, the formwork was not stable enough and was prone to shifting as the concrete was laid. Second, there was a slight height error between the top of the metal trim of the formwork and the design elevation of the concrete, which reduced the compartmentalization effect of the formwork and the aesthetics of the metal trim. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a combined template for simultaneous molding of concrete leveling and metal edging, so as to solve the technical problems in the background art.

[0006] This utility model provides the following technical solution:

[0007] A combined formwork for simultaneous concrete leveling and metal edging includes a non-removable formwork, which comprises a horizontal section and a vertical section. The upper end of the vertical section is provided with a metal edging. The formwork also includes an anti-sinking base plate located below the horizontal section. The anti-sinking base plate is connected to the non-removable formwork via a fine-tuning leveling height assembly. The fine-tuning leveling height assembly includes a screw vertically located at the upper end of the anti-sinking base plate. The horizontal section has a first circular opening for the screw to pass through. An adjusting nut is fitted on the screw below the first circular opening, and a fastening nut is fitted on the screw above the first circular opening.

[0008] Preferably, the lower end of the screw is provided with a pre-embedded seat, which is located inside the anti-sinking substrate. The upper surface of the anti-sinking substrate is also provided with a first blind hole, which is coaxially arranged with the screw, and the bottom of the first blind hole is higher than the upper surface of the pre-embedded seat.

[0009] Preferably, the anti-sinking base plate is a precast concrete structure, the anti-sinking base plate is cuboid in shape, the length direction of the anti-sinking base plate is arranged along the length direction of the non-removable template, and the length of the anti-sinking base plate is not greater than the length of the non-removable template.

[0010] Preferably, a plurality of fine-tuning leveling height components are provided, and the plurality of fine-tuning leveling height components are arranged at equal intervals along the length direction of the anti-sinking substrate.

[0011] Preferably, the metal trim is U-shaped and snaps into the upper end of the vertical section. The length of the metal trim is the same as the length of the removable template. The metal trim is connected to the vertical section through a connector.

[0012] Preferably, the connector includes a second circular opening penetrating the front and rear sides of the vertical section, a third circular opening penetrating both sides of the metal edging, and a rivet for connecting the horizontal section and the metal edging. The second and third circular openings are coaxially arranged to allow the rivet to pass through.

[0013] Preferably, a plurality of connectors are provided, and the plurality of connectors are arranged sequentially at equal intervals along the length direction of the metal edging.

[0014] Preferably, the horizontal segment is further provided with a plurality of fifth circular openings running vertically through it, and the plurality of fifth circular openings are evenly arranged in a rectangular array.

[0015] Preferably, the four corner positions of the anti-sinking substrate are respectively provided with a fourth circular opening that runs vertically through the substrate for the anchor rod to pass through, and the upper end surface of the anti-sinking substrate is respectively provided with a second blind hole at each of the fourth circular opening positions.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The present invention provides a combined template for simultaneous molding of concrete leveling and metal edging.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] This utility model provides a combined formwork for simultaneous concrete leveling and metal edging molding, see reference. Figure 1-4 The system includes a non-removable template 1, which comprises a horizontal section 2 and a vertical section 3. The non-removable template 1 is L-shaped or T-shaped. The upper end of the vertical section 3 is provided with a metal edging 4. The system also includes an anti-sinking base plate 5 located below the horizontal section 2. The anti-sinking base plate 5 is connected to the non-removable template 1 through a fine-tuning leveling height component 6. The fine-tuning leveling height component 6 includes a screw 61 vertically located at the upper end of the anti-sinking base plate 5. The horizontal section 2 is provided with a first circular opening 62 for the screw 61 to pass through. An adjusting nut 63 is adapted to the screw 61 below the first circular opening 62, and a fastening nut 64 is adapted to the screw 61 above the first circular opening 62. By turning the adjusting nut 63, it can be moved up or down. The outer ring of the adjusting nut 63 is larger than the diameter of the first circular opening 62, which can support the horizontal section 2. The height of the upper end of the adjusting nut 63 is the bottom height of the non-removable template 1. The leveling height can be finely adjusted by ±10mm, which facilitates the fine adjustment of the top height of the metal edging 4, so that the top of the metal edging 4 is on the same horizontal plane as the concrete leveling height, and so that the top of the metal edging 4 can be adjusted to the design elevation. The leveling height can be checked with a laser during construction. After the adjusting nut 63 is adjusted, the non-removable template 1 is placed in and then tightened by the fastening nut 64.

[0028] The anti-sinking base plate 5 is a precast concrete structure. The anti-sinking base plate 5 is cuboid in shape, and its length is aligned with the length of the non-removable formwork 1. The length of the anti-sinking base plate 5 is not greater than the length of the non-removable formwork 1, and its width is not less than the width of the horizontal segment 2. During construction, a cuboid-shaped pit is excavated in the base layer to place the anti-sinking base plate 5. The anti-sinking base plate 5 improves the stability of the non-removable formwork 1, facilitates fine-tuning of its height, and reduces the possibility of later sinking.

[0029] A pre-embedded seat 65 is provided at the lower end of the screw 61. The pre-embedded seat 65 is located inside the anti-sinking base plate 5. A first blind hole 66 is also provided on the upper end surface of the anti-sinking base plate 5. The first blind hole 66 is coaxially arranged with the screw 61, and the bottom of the first blind hole 66 is higher than the upper end surface of the pre-embedded seat 65. The pre-embedded seat 65 is cross-shaped and is used to improve the stability of the screw 61 during pre-embedding and support. The diameter of the first blind hole 66 is larger than the outer diameter of the adjusting nut 63. Because the adjusting nut 63 has a certain thickness, it is convenient for the adjusting nut 63 to move into the first blind hole 66 during adjustment, reducing the influence of the height of the adjusting nut 63 on the lower end surface of the horizontal section 2.

[0030] Several fine-tuning leveling height components 6 are provided, and these components are arranged at equal intervals along the length of the anti-sinking base plate 5. This further improves the stability when supporting the formwork 1. When laying concrete, the concrete needs to fill the gap between the anti-sinking base plate 5 and the formwork 1, further improving the stability of the formwork 1.

[0031] The metal edging 4 is inverted U-shaped and engages with the upper end of the vertical section 3. The length of the metal edging 4 is the same as the length of the removable template 1. The metal edging 4 is connected to the vertical section 3 via a connector 7. The metal edging 4 is made of aluminum alloy and has a rust-proof metal edging effect.

[0032] The connector 7 includes a second circular opening 71 penetrating the front and rear sides of the vertical section 3, a third circular opening 72 penetrating both sides of the metal edging 4, and a rivet 73 for connecting the horizontal section 2 and the metal edging 4. The second circular opening 71 and the third circular opening 72 are coaxially arranged to allow the rivet 73 to pass through. This improves the stability of the connection between the metal edging 4 and the vertical section 3.

[0033] A plurality of connectors 7 are provided, and the plurality of connectors 7 are arranged at equal intervals along the length direction of the metal edging 4.

[0034] The horizontal segment 2 is also provided with several fifth circular openings 11 running vertically through it, and these fifth circular openings 11 are evenly arranged in a rectangular array. When laying concrete, the concrete can fill the gap between the anti-settlement base plate 5 and the non-removable template 1 through the fifth circular openings 11, further improving the stability of the non-removable template 1.

[0035] The anti-settlement base plate 5 has four vertically penetrating fourth circular openings 8 for anchor rods 9 to pass through at its four corners. A second blind hole 10 is coaxially provided on the upper surface of the anti-settlement base plate 5 at each of the fourth circular openings 8. Before concrete laying, the anti-settlement base plate 5 is placed in the foundation pit and fixed to the base layer by four anchor rods 9. The second blind holes 10 reduce the impact of the upper ends of the anchor rods 9 on the lower surface of the horizontal section 2.
