Description

Technical Field

[0001] This utility model relates to a building formwork system, specifically a large column splicing formwork system. Background Technology

[0002] Construction formwork is used to provide the concrete with the required shape, size, and surface quality during the concrete pouring process, while bearing the weight of the concrete and various loads during construction, until the concrete hardens and reaches sufficient strength before being removed.

[0003] Existing building formwork requires fixing with timber and tie bolts, which is complex and inefficient. For casting large columns, such as those with sides greater than 2 meters, the formwork is subjected to heavy loads during casting, but tie bolts cannot be used for reinforcement. As a result, problems such as bulging and grout leakage are prone to occur during construction, especially in the middle and corner sections.

[0004] Therefore, there is an urgent need for a large column splicing formwork system that can be quickly assembled and effectively fixed to avoid problems such as bulging and grout leakage. Utility Model Content

[0005] The purpose of this utility model is to provide a large column splicing formwork system to solve the problems of low efficiency and easy occurrence of formwork bulging and grout leakage in the construction process of existing building formwork.

[0006] This utility model is implemented as follows: a large column splicing template system, comprising: Side templates are located on the four sides of the column and are formed by splicing together several standard templates and at most one adjustable template. Corner reinforcement components are installed between two adjacent side templates to connect with both adjacent side templates simultaneously. A fixing rod is provided on the outside of the four side templates. The four fixing rods are connected end to end in sequence to fix the side templates. The fixing rod includes a long strip-shaped main plate and a first reinforcing plate. The length of the first reinforcing plate is less than the length of the main plate. The first reinforcing plate is located in the middle of the outer side of the main plate. The first reinforcing plate and the main plate are located on the same plane. Connectors are used to connect standard templates, adjustable templates, and corner reinforcement components.

[0007] As a further improvement of this utility model, a hook is provided at one end of the main body plate, and several insertion holes are provided on the surface of the other end of the main body plate; when connecting, the end of one main body plate with the insertion hole passes through the hook at the end of the adjacent main body plate, and a wedge plate is inserted into one of the insertion holes, with one side of the wedge plate contacting the hook.

[0008] As a further improvement of this utility model, reinforcing ribs are provided on the sides of the main body plate and the first reinforcing plate.

[0009] As a further improvement of this utility model, a second reinforcing plate is provided on the outer side of the first reinforcing plate.

[0025] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] like Figure 1 As shown, this utility model is a large column splicing template system, the structure of which includes side templates, corner reinforcement parts 3, fixing rods 4 and connectors 5, etc.

[0028] There are four side templates, located on the four sides of the column. Each side template is formed by joining several standard templates 1 and at most one adjustable template 2. The dimensions of the standard templates 1 are fixed; multiple standard templates 1 are joined together as needed, and the remaining portion is supplemented by the adjustable template 2, the dimensions of which are determined according to specific requirements. When the width of the side template is exactly a multiple of the width of the standard template 1, only several standard templates 1 are needed to form the side template, eliminating the need for the adjustable template 2. The standard templates 1 and adjustable template 2 can accommodate column structures of different sizes.

[0029] Two adjacent side formwork panels form a right-angle structure at the corner. A corner reinforcement 3 is installed at the corner. The corner reinforcement 3 consists of two side plates that are perpendicular to each other, forming a right-angle structure. The width of the side plates of the corner reinforcement 3 is the same as the thickness of the side formwork. The two side plates of the corner reinforcement 3 are connected to the two adjacent side formwork panels respectively. By connecting the two perpendicular side formwork panels with the corner reinforcement 3, deformation and grout leakage problems at the corner can be avoided.

[0030] The standard templates 1 are connected to each other, the standard template 1 is connected to the adjusting template 2, and the side templates are connected to the corner reinforcement 3 via connectors 5. Preferably, the connections between the above structures use the same standard connectors 5, which can reduce construction costs and improve splicing efficiency.

[0031] Among them, such as Figure 5 As shown, the standard template 1 includes a first panel 1-1, with first side ribs 1-2 respectively provided on both sides of the back of the first panel 1-1, and a first back rib 1-3 provided on the back of the first panel 1-1. The length directions of the first side ribs 1-2 and the first back ribs 1-3 are consistent. A first connecting hole 1-4 is provided on the first side rib 1-2, and the axis of the first connecting hole 1-4 is parallel to the first panel 1-1.

[0032] like Figure 6 As shown, the adjusting template 2 includes a second panel 2-1. Second side ribs 2-2 are respectively provided on both sides of the back of the second panel 2-1. Second connecting holes 2-4 are formed on the second side ribs, with the axis of the second connecting holes 2-4 parallel to the second panel 2-1. The thickness of the second panel 2-1 is the same as the thickness of the first panel 1-1, and the thickness of the second side ribs 2-2 is the same as the thickness of the first side ribs 1-2. When the distance between the two second side ribs 2-2 of the adjusting template 2 is large, a second back rib 2-3 is added to the back of the second panel 2-1. The position of the second connecting hole 2-4 corresponds to the position of the first connecting hole 1-4.

[0033] When assembling the side templates, the standard template 1 and the adjusting template 2 are set up side by side, with the side ribs of the adjacent templates fitting together. The templates can be connected and fixed by passing the connector 5 through the connecting hole.

[0034] A third connecting hole is provided on the side plate of the corner reinforcement 3. The position of the third connecting hole corresponds to the position of the first connecting holes 1-4. After the two adjacent side templates are spliced ​​together, the corner reinforcement 3 is placed at the corner. The side ribs of the side templates are fixedly connected to the side plate of the corner reinforcement 3 through the connector 5.

[0035] The standard template 1 and the adjusting template 2 can be made of metal or high-strength plastic. The corner reinforcement 3 is generally made of metal.

[0036] The connector 5 can be a bolt, a fixing pin, a plug, etc. In this embodiment, a bolt is specifically selected.

[0037] Since the side template is assembled from standard template 1 and adjustable template 2, the size of the side template can be adjusted by the number of standard template 1 and the size of the adjustable template 2. The standard template 1, adjustable template 2 and corner reinforcement 3 can be quickly connected by connector 5. The side template is positioned by fixing rod 4. The entire template system can be quickly assembled, improving efficiency.

[0038] After the four side templates are connected to each other, fixing rods 4 are set on the outside of the four side templates respectively. The four fixing rods 4 are connected in sequence to fix the side templates, thereby strengthening the casting template.

[0039] like Figure 2 , Figure 3 as well as Figure 4 As shown, the fixing rod 4 includes a main body plate 4-1 and a first reinforcing plate 4-2. Both the main body plate 4-1 and the first reinforcing plate 4-2 are elongated structures. The length of the first reinforcing plate 4-2 is less than the length of the main body plate 4-1. The first reinforcing plate 4-2 is located in the middle of the outer side of the main body plate 4-1, and the first reinforcing plate 4-2 and the main body plate 4-1 are located on the same plane.

[0040] In use, the plane on which the main body plate 4-1 is located is perpendicular to the plane template. The inner side of the main body plate 4-1 contacts the back ribs and side ribs of the plane template, giving the main body plate 4-1 strong bending resistance on its plane. The first reinforcing plate 4-2 located on the outer side of the main body plate 4-1 further increases the overall bending resistance of the fixing rod 4.

[0041] To further increase the overall bending resistance of the fixing rod 4 and the bending resistance of the middle part of the fixing rod 4, a second reinforcing plate 4-3 is provided on the outside of the first reinforcing plate 4-2. The length of the second reinforcing plate 4-3 is less than that of the first reinforcing plate 4-2. The second reinforcing plate 4-3 is located in the middle of the outer side of the first reinforcing plate 4-2. The second reinforcing plate 4-3 and the first reinforcing plate 4-2 are located on the same plane.

[0042] To improve the overall structural strength of the fixing rod 4 and its resistance to deformation in the direction perpendicular to its surface, reinforcing ribs 4-4 are provided on the sides of the main body plate 4-1 and the first reinforcing plate 4-2. The reinforcing ribs 4-4 protrude from the upper and lower surfaces of the main body plate 4-1.

[0043] Furthermore, when a second reinforcing plate 4-3 is provided, a reinforcing rib 4-4 is also provided on the side of the second reinforcing plate 4-3.

[0044] The ends of the first reinforcing plate 4-2 and the second reinforcing plate 4-3 are inclined edges.

[0045] The fixing rod 4 consists of a main plate 4-1 and a reinforcing plate. The reinforcing plate enhances the bending resistance of the middle part of the fixing rod 4, thereby effectively improving the fixing effect on the middle part of the side template and avoiding the problems of bulging of the side template and leakage of grout at the template joint.

[0046] Two adjacent fixed rods 4 are connected to each other by a main body plate 4-1. Two adjacent main body plates 4-1 are connected by a hook 4-5 and a wedge plate 6. One side of the wedge plate 6 is a vertical edge, and the other side is an inclined edge.

[0047] A hook 4-5 is provided at one end of the main body plate 4-1, and several insertion holes 4-6 are provided on the surface of the other end of the main body plate 4-1. When the two main body plates 4-1 are connected to each other, the end of one main body plate 4-1 with the insertion hole 4-6 passes through the hook 4-5 at the end of the other main body plate 4-1. A wedge plate 6 is inserted into a corresponding insertion hole 4-6 according to the length of the end with the insertion hole 4-6 extending out. The vertical edge of the wedge plate 6 contacts the hook 4-5, and the inclined edge of the wedge plate 6 contacts the end of the insertion hole 4-6.

[0048] Specifically, two rows of insertion holes 4-6 are provided at the end of the main body plate 4-1. Each row of insertion holes 4-6 is evenly distributed along the length of the main body plate 4-1, and the two rows of insertion holes 4-6 are staggered. In use, one of the insertion holes 4-6 in the two rows is selected as needed to insert the wedge plate 6, and the relative position of the connection between the two main body plates 4-1 is fine-tuned by adjusting the insertion depth of the wedge plate 6.

[0049] In this utility model, the standard template 1, corner reinforcement 3, connector 5, and fixing rod 4 can be reused repeatedly. Only the template 2 is adjusted to make non-standard parts of special size according to the specific structural dimensions, which can greatly reduce construction costs and improve the efficiency of material preparation.

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
