Description

Technical Field

[0001] The invention relates to a building template, in particular to a wedge plate with an easily dismantled template structure and a use method thereof. Background Art

[0002] Building formwork is used for temporary support during concrete pouring, so that concrete structures and components can be formed according to the specified position and geometric dimensions. After the concrete is solidified and formed, the building formwork needs to be removed. Since the formworks are tightly spliced, it is difficult to remove the formwork. A large force is required to remove the formwork, which can easily damage or deform the formwork. Existing aluminum formworks have easy-to-remove structures, such as CN209556351U, CN202937003U, etc., in which the side ribs of the formwork are designed as inclined structures to facilitate the removal of the formwork. The above structure leads to the emergence of a large number of non-standard parts. Corresponding easy-to-remove formworks need to be designed for different positions of the building structure. Special formworks have poor versatility and low utilization, which increases the production cost and use cost of the formwork.

[0003] Therefore, there is an urgent need for a universal, easily dismantled structure that can be flexibly used in different locations of the building structure to save the production and use costs of the formwork. Summary of the invention

[0004] The purpose of the present invention is to provide a wedge plate of an easily dismantled template structure and a use method thereof, so as to solve the problems of poor versatility and high cost of existing easily dismantled templates.

[0005] The present invention is achieved as follows: a wedge plate of a template easy-to-remove structure includes a main body, the cross-section of the main body is a right-angled trapezoidal structure, the main body is provided with a bottom surface and a top surface parallel to each other, one side of the main body is a side rib surface perpendicular to the top surface and the bottom surface, and the other side is a wedge surface, the angle between the wedge surface and the bottom surface is an acute angle, a plurality of connecting holes are provided on the side rib surface along the longitudinal center axis, and straight holes are provided at both ends of the side rib surface respectively, and spacer ribs are provided between the straight hole and the adjacent connecting holes and between two adjacent connecting holes, the straight hole is open on the end surface of the main body, a connecting hook is provided at one end of the main body, the connecting hook extends out of the main body along the length direction, and a connecting sill is provided in the straight hole at the other end of the main body to match the connecting hook, when two wedge plates are aligned end to end along the length direction, the connecting hook and the connecting sill form a positioning bite structure.

[0006] When the two wedge plates are assembled into a rectangular column, they can move along the wedge surface without obstacles unless a pin structure is artificially inserted into the connecting hole.

[0007] Furthermore, one side surface of the spacer rib coincides with the side rib surface, and the spacer rib on one side of the wedge surface includes an inclined section and a straight section, the inclined section close to the top surface coincides with the wedge surface, and the straight section close to the bottom surface is perpendicular to the bottom surface, and the inclined section and the straight section have a smooth transition.

[0008] Furthermore, the connecting hook is located on the side of the smooth hole close to the bottom surface, and the end of the connecting hook is bent toward the bottom surface; the connecting sill is located on the side of the smooth hole close to the bottom surface, and the connecting sill is a protruding structure at the lower part of the smooth hole, so that the connecting sill of one wedge plate can be hooked with the connecting hook of another wedge plate that is in contact with the smooth hole.

[0009] Furthermore, sealing grooves are respectively provided at the upper and lower edges of the side rib surface.

[0010] Furthermore, hole ribs are respectively provided on the upper and lower sides of the connecting hole, one side surface of the hole rib is flush with the side rib surface, and the other side surface is lower than the spacer rib.

[0011] Furthermore, the connection holes are distributed along the length of the side rib surface toward the central axis, the connection holes are long strip holes, and the inner wall surface of the connection holes is perpendicular to the side rib surface.

[0012] Furthermore, when used as an easily detachable unit, two identical wedge plates are stacked upside down and aligned, and the wedge surfaces are in contact with each other, and the cross-section presents a rectangular structure; or one wedge plate is a standard wedge plate, and the top surface of the other wedge plate is extended outward to form a limiting wedge plate, and the standard wedge plate and the limiting wedge plate are stacked upside down, the top surface of the standard wedge plate is flush with the bottom surface of the limiting wedge plate, and the top surface of the limiting wedge plate protrudes from the bottom surface of the standard wedge plate.

[0013] The invention also discloses a method for using a wedge plate, which includes the following contents.

[0014] The two wedge plates are stacked upside down to form an easily removable unit, and then the two easily removable units are aligned head to tail so that the connecting hook of one easily removable unit is hooked with the connecting ridge of the other easily removable unit. After completing the above operations, templates are assembled on both sides of the easily removable unit, and the side rib surfaces are pressed against the assembled templates so that the connecting holes of the templates and the connecting holes of the wedge plates are aligned up and down, and the templates and the clamped easily removable units are connected and fixed by connecting pieces passing through the connecting holes, and the bottom surface of the wedge plate is close to the back rib surface of the template that is removed first.

[0015] When demoulding the easily dismantled structure, first take out all the connectors that clamp the easily dismantled unit, and then move the template in a direction perpendicular to the back rib of the template to remove the template and its adjacent wedge plates.

[0016] Furthermore, when used with standard plates:

[0017] When installing the building formwork, two identical wedge plates are stacked upside down to form an easily removable unit. Standard plates are spliced ​​on the side rib surfaces of the two wedge plates respectively. The bottom surface of one wedge plate is flush with the side rib of the adjacent standard plate. The standard plate is the formwork removed first. The bottom surface of the other wedge plate is flush with the board surface of the adjacent standard plate. Connectors are used to pass through the connecting holes of the two standard plates and the connecting holes of the two wedge plates to fix the two standard plates and the clamped easily removable unit.

[0018] When disassembling the building formwork, the connecting pieces on the easily disassembled unit are removed, and then the first-disassembled formwork is moved outward, so that the first-disassembled formwork and the wedge plate adjacent thereto are disengaged outward.

[0019] When used for inner corner panels:

[0020] When installing the building formwork, a universal board is used as the inner corner formwork. One side of the universal board is connected to the standard board, and an easily removable unit formed by two wedge plates stacked upside down is sandwiched between the other side and the standard board. Adjacent easily removable units are aligned head to tail so that the connecting ridges and connecting hooks are hooked to form an easily removable structure at the inner corner. The bottom surface of the wedge plate away from the universal board is located on the back rib side of the adjacent standard formwork, so that the connecting holes of the standard formwork, wedge plate and universal board are aligned up and down, and the universal board, standard board and the sandwiched easily removable unit are connected using connectors.

[0021] When disassembling the building formwork, the connecting pieces on the easily removable unit are removed, and the easily removable unit and the adjacent standard formwork are moved outward in a direction perpendicular to the concrete surface, and the standard formwork and the wedge plate adjacent thereto are demoulded.

[0022] Furthermore, when used for inner corner plates, the wedge plate close to the universal plate is replaced with a limiting wedge plate. After assembly, the top surface of the limiting wedge plate extends out of the edge of the universal plate, thereby pressing against the standard template of the other wing of the inner corner to form a limiting structure.

[0023] The wedge plate of the present invention has a wedge-shaped cross section. Two wedge plates are stacked upside down to form a basic easy-to-disassemble unit, which is clamped with other templates to form an easy-to-disassemble structure. The two wedge plates of the easy-to-disassemble unit are connected by a wedge surface, and the wedge plates can be removed outward along the wedge surface, thereby realizing the rapid disassembly of the template.

[0024] Two adjacent wedge plates in the length direction are connected by a bite structure to ensure that there is no gap between the wedge plates. The position where the two wedge plates are connected end to end can also be used to install the template connector, which improves the flexibility of the easy-to-remove unit.

[0025] When the top surface of a wedge plate in the easily removable unit is extended outward to form a limiting wedge plate, the inward movement of the template can be limited, thereby ensuring the molding quality of the concrete.

[0026] The easily detachable unit composed of two wedge plates can be clamped between different templates to form different easily detachable structures of building templates with different templates. It has good versatility, and the wedge plate can be produced and used as a standard part, which can greatly reduce the production cost and use cost of the easily detachable structure.

DETAILED DESCRIPTION

[0037] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0039] like Figure 1 , Figure 2 as well as Figure 3 As shown, the wedge plate 1 of the template easy-to-remove structure of the present invention includes a body 1-1, and the four upper, lower, left and right surfaces of the body 1-1 are respectively a top surface 1-4, a bottom surface 1-5, a side rib surface 1-2 and a wedge surface 1-3. The bottom surface 1-5 and the top surface 1-4 of the body 1-1 are parallel to each other, one side of the body 1-1 is the side rib surface 1-2, and the other side is the wedge surface 1-3. Among them, the side rib surface 1-2 is perpendicular to the bottom surface 1-5, and the angle between the wedge surface 1-3 and the bottom surface 1-5 is an acute angle. From the end face or the cross section, the body 1-1 is a right-angled trapezoidal structure. Since the top surface 1-4 is generally smaller in width, it can also be approximately considered as a wedge-shaped structure.

[0040] The two wedge plates 1 can be assembled together to form an easily disassembled module. The easily disassembled module can be used in different building template structures. The template structure can be quickly disassembled by the relative displacement of the two wedge plates 1.

[0041] A plurality of connecting holes 1-6 are provided on the side rib surface 1-2 along the length direction of the main body 1-1. The connecting holes 1-6 are located on the longitudinal center axis of the side rib surface 1-2. A longitudinal hole 1-8 is provided at both ends of the main body 1-1. The longitudinal hole 1-8 and the adjacent connecting holes 1-6 and the two adjacent connecting holes 1-6 are separated by a spacer rib 1-7. The connecting holes 1-6 and the longitudinal holes 1-8 enable the connecting parts to pass through the main body 1-1 of the wedge plate 1 to connect the templates on both sides of the easily detachable module.

[0042] The longitudinal hole 1-8 opens on the end face of the main body 1-1. When the two wedge plates 1 are connected end to end in the length direction, the longitudinal holes 1-8 at the ends of the two wedge plates 1 are spliced ​​together to form a connecting hole 1-6. The connecting piece can pass through the connecting hole 1-6 formed by splicing the two longitudinal holes 1-8, so there is no restriction on the installation position of the connecting piece, and the connecting piece can be inserted even at the connection between the two wedge plates 1.

[0043] A connecting hook 1-9 is provided at one end of the body 1-1, and a connecting sill 1-10 is provided at the other end to match the connecting hook 1-9. When the two wedge plates are aligned end to end along the length direction, the connecting hook 1-9 and the connecting sill 1-10 form a positioning bite structure. Figure 8 , Fig. 9 As shown, the positioning and engaging structure formed by the connecting hook 1 - 9 and the connecting step 1 - 10 can enable the two wedge plates 1 to be quickly connected to each other, thereby preventing a gap from being formed between the end faces of the two wedge plates 1 .

[0044] Furthermore, the connecting hook 1-9 is arranged on the end face of the main body 1-1 and extends out of the end face along the length direction of the main body 1-1. The connecting sill 1-10 is located in the longitudinal hole 1-8. When the two wedge plates 1 are connected end to end, the connecting hook 1-9 at the end of one wedge plate 1 extends into the longitudinal hole 1-8 at the end of the other wedge plate 1, and the connecting hook 1-9 and the connecting sill 1-10 are engaged with each other.

[0045] The connecting hook 1-9 is located on the side of the opening of the shunting hole 1-8 close to the bottom surface 1-5 of the main body 1-1, and the end of the connecting hook 1-9 is bent toward the bottom surface 1-5 of the main body 1-1; the connecting sill 1-10 is located in the shunting hole 1-8 close to the bottom surface 1-5 of the main body 1-1, and the connecting sill 1-10 is a protruding structure at the lower part of the shunting hole 1-8 so that the end of the connecting hook 1-9 can be hooked.

[0046] When in use, the easily removable module formed by two wedge plates 1 is clamped between the templates on both sides, and the wedge plates 1 can only be removed outward along the wedge surface 1-3. When an easily removable module is connected with a connector, the two wedge plates 1 of the easily removable module cannot move relative to each other. At the same time, the positioning and interlocking structure formed by the connecting hook 1-9 and the connecting step 1-10 can prevent the two wedge plates 1 of adjacent easily removable modules from moving relative to each other.

[0047] Hole ribs 1-12 are provided on the upper and lower sides of the connecting hole 1-6 respectively. The distance between the upper and lower hole ribs 1-12 can just accommodate the passage of the connecting piece. One side surface of the hole rib 1-12 is flush with the side rib surface 1-2, and the other side surface is lower than the spacer rib 1-7.

[0048] A hole rib 1-12 consistent with the connecting hole 1-6 is also provided in the longitudinal hole 1-8, and the upper and lower limit positions of the connecting hook 1-9 coincide with the upper and lower edges of the hole rib 1-12, so that the connecting hook 1-9 will not protrude from the edge of the hole rib 1-12, and will not affect the normal connection of the connecting piece at the connecting hole 1-6 formed by splicing two longitudinal holes 1-8.

[0049] The connection hole 1-6 is specifically a rectangular hole, and the inner wall surface of the connection hole 1-6 is perpendicular to the side rib surface 1-2.

[0050] One side of the spacer rib 1-7 overlaps with the side rib surface 1-2. The spacer rib 1-7 located on the side of the wedge surface 1-3 includes an inclined section 1-7-1 and a straight section 1-7-2, wherein the inclined section 1-7-1 is close to the top surface 1-4 of the body 1-1, and the straight section 1-7-2 is close to the bottom surface 1-5 of the body 1-1. The inclined section 1-7-1 overlaps with the plane where the wedge surface 1-3 is located, while the straight section 1-7-2 is parallel to the side rib surface 1-2, and there is a smooth transition between the inclined section 1-7-1 and the straight section 1-7-2.

[0051] When using, Figure 7 As shown, the two wedge plates 1 are inverted and stacked together, and the wedge surfaces 1-3 of the two wedge plates 1 fit each other. For the middle part, the connecting hole 1-6 is designed to be sunken on one side of the wedge surface 1-3, so the surfaces of the connecting holes 1-6 of the two wedge plates 1 will not contact each other. For the spacer rib 1-7 part, since the spacer rib 1-7 is divided into an inclined section 1-7-1 and a straight section 1-7-2, after the two wedge plates 1 are inverted, the inclined section 1-7-1 of the spacer rib 1-7 of one wedge plate 1 will not contact the straight section 1-7-2 of the spacer rib 1-7 of the other wedge plate 1, that is to say, the spacer rib 1-7 parts of the two wedge plates 1 will not contact each other. Therefore, the fitting surfaces of the two wedge plates 1 are the plate surface parts at the upper and lower parts of the connecting holes 1-6. Through this design, on the one hand, the stability of the fitting of the wedge surfaces 1-3 of the two wedge plates 1 can be ensured, and on the other hand, the area and width of the fitting surface can be reduced, so that the two wedge plates 1 can be detached from each other after being offset by a very small distance, making the disassembly of the template easier.

[0052] Sealing grooves 1-11 are provided at the upper and lower edges of the side rib surface 1-2. Since the side rib surface 1-2 is the functional surface in contact with and connected to other templates, during the process of pouring concrete, under the pressure of the concrete itself and the action of vibration, water seeping from the mortar will flow into the sealing groove 1-11 through the gap, and the water filling the sealing groove 1-11 can form a damming effect, which has a decelerating and hysteresis effect on the water flowing out of the bridge slab gap at a high speed, thereby reducing the speed of water loss in the mortar. In addition, during the construction process, the floating slurry in the concrete may also flow into the sealing groove 1-11, and the floating slurry in the sealing groove 1-11 can also play a water-blocking role. In this way, under the dual effects of the seepage water and the floating slurry flowing into the sealing groove 1-11, the rapid water screening effect formed by the water-repellent plastic template can be effectively overcome, thereby achieving a good sealing effect.

[0053] The wedge plate 1 is connected to other templates through the connecting holes 1-6. Since in other building templates, the connecting structures of the templates (generally the connecting holes) are evenly distributed, the connecting holes 1-6 of the wedge plate 1 are also evenly distributed along the length direction of the body 1-1, and the positions of the connecting holes 1-6 correspond to the positions of the connecting structures of the templates.

[0054] The wedge plate connecting holes 1-6 are generally long holes.

[0055] Two wedge plates 1 of the present invention are stacked upside down to form an easily detachable unit, and the easily detachable unit has two forms.

[0056] In the first form, if Figure 4 As shown, two identical wedge plates 1 are stacked upside down to form a rectangular structure in cross section. Both wedge plates 1 are standard wedge plates 1.

[0057] In the second form, Figure 5 , Figure 6 As shown, one wedge plate 1 is a standard wedge plate 1, and the top surface 1-4 of the other wedge plate 1 is extended outward to form a limiting wedge plate 1, the standard wedge plate 1 and the limiting wedge plate 1 are stacked upside down, the top surface 1-4 of the standard wedge plate 1 is flush with the bottom surface 1-5 of the limiting wedge plate 1, and the top surface 1-4 of the limiting wedge plate 1 protrudes from the bottom surface 1-5 of the standard wedge plate 1. The protruding portion can limit the template from moving inward to ensure the quality of concrete molding during pouring.

[0058] The present invention also discloses a method for using the wedge plate 1, which specifically includes two parts: installation and disassembly of the building template.

[0059] When installing the building formwork, two wedge plates 1 are stacked upside down to form an easily removable unit. In the length direction, two adjacent easily removable units are connected end to end by connecting hooks 1-9 and connecting steps 1-10. The formwork is spliced ​​on the side rib surfaces 1-2 of the two wedge plates 1 respectively. The easily removable unit is clamped between the two formworks. The bottom surface of one wedge plate 1 is flush with the side rib of the adjacent standard plate 2. The standard plate 2 is the first-removed formwork (the formwork to be removed first). The bottom surface of the other wedge plate 1 is flush with the board surface of the adjacent standard plate 2. Connectors are used to pass through the connecting structure of the formwork and the connecting holes 1-6 of the two wedge plates 1 to fix the formworks on both sides to the two wedge plates 1 together.

[0060] When disassembling the building template, first remove the connector on the easily disassembled unit, then move the template on one side of the easily disassembled unit outwards, so that the template and the wedge plate 1 adjacent thereto are disengaged outwards.

[0061] Different templates can be assembled on both sides of the easily disassembled unit as needed to form the required building template structure, which can be specifically applied to the standard template 3 and the templates at the corners.

[0062] When used with standard plates:

[0063] like Fig.10As shown, when installing the building formwork, two identical wedge plates 1 are stacked upside down to form an easily removable unit, and several easily removable units are connected end to end as needed. Standard plates 2 are spliced ​​on the side rib surfaces 1-2 of the two wedge plates 1, respectively. The thickness of the easily removable unit is consistent with the thickness of the standard plate 2. The positions of the connecting holes 1-6 on the wedge plates 1 correspond to the positions of the connecting holes on the side ribs of the standard plate 2. The bottom surface 1-5 of one wedge plate 1 is flush with the side ribs of the adjacent standard plate 2. The standard plate 2 is the first to be removed from the formwork. The bottom surface 1-5 of the other wedge plate 1 is flush with the board surface of the adjacent standard plate 2. Connectors are used to pass through the connecting holes of the two standard plates 2 and the connecting holes 1-6 of the two wedge plates 1 to fix the two standard plates 2 with the easily removable unit to form an easily removable structure of the standard plate 2.

[0064] When pouring concrete, the face plate of standard slab 2 is in contact with the concrete surface.

[0065] When disassembling the building formwork, first remove the connecting parts on the easily disassembled unit, and then move the first-disassembled formwork outward by pulling outward and vibrating. Under the action of external force, the wedge plate 1 adjacent to the first-disassembled formwork moves outward along the wedge surface 1-3. After shifting a certain distance, the two wedge plates 1 separate from each other, thereby causing the first-disassembled formwork and the wedge plate 1 adjacent to it to slip outward.

[0066] Among them, the connecting piece can be specifically a mold bolt 5, and the structure of the mold bolt 5 can be specifically referred to CN204590612U and CN204590609U.

[0067] When used for inner corner panels:

[0068] like Fig.11 , Fig.12 As shown, when installing the building formwork, the standard formwork 3 is spliced ​​on two adjacent surfaces of the universal plate 4 to form an inner corner formwork, and an easily removable unit formed by two wedge plates 1 stacked upside down is arranged between the universal plate 4 and one of the standard formworks 3. The thickness of the easily removable unit is consistent with the thickness of the universal plate 4 and the thickness of the standard formwork 3. The position of the connecting hole 1-6 on the wedge plate 1 corresponds to the position of the connecting structure on the universal plate 4 and the standard formwork 3. According to the needs, several easily removable units are connected end to end, and the connecting ridge 1-10 and the connecting hook 1-9 are hooked. Among them, the side rib surface 1-2 of one wedge plate 1 is in contact with one side surface of the universal plate 4, and the side rib surface 1-2 of the other wedge plate 1 is in contact with the side rib of the standard formwork 3. The bottom surface 1-5 of the wedge plate 1 away from the universal plate 4 is flush with the side rib of the adjacent standard formwork 3. A connector is used to pass through the connecting holes of the universal plate 4, the two wedge plates 1 and the standard formwork 3 to connect the universal plate 4, the easily removable unit and the standard formwork 3 to form an easily removable structure of the inner corner plate.

[0069] When pouring concrete, the plate surfaces of the two standard formworks 3 are in contact with the concrete surface.

[0070] When disassembling the building formwork, first remove the connecting parts on the easily removable unit, and then move the standard formwork 3 adjacent to the easily removable unit outward by pulling outward and vibrating. Under the action of external force, the wedge plate 1 away from the universal plate 4 is displaced outward along the wedge surface 1-3. After displacing a certain distance, the two wedge plates 1 are separated from each other, so that the standard formwork 3 and the wedge plates 1 adjacent to it are dislodged outward.

[0071] The universal plate 4 includes a connecting hole portion and a skylight portion, the connecting hole portion and the skylight portion are used to connect the connectors in two directions, the connecting hole portion is used to connect the conventional mold bolt 5, etc., and the skylight portion is used to connect the mold cylinder 6 and the connecting bolt 7. The specific structure of the universal plate 4, the mold cylinder 6 and the connecting bolt 7 can refer to CN209603479U.

[0072] When used for inner angle plates, in one embodiment of the present invention, for one or more easily detachable units, the top surface 1-4 of the wedge plate 1 close to the universal plate 4 is extended outward to form a limiting wedge plate 1, and the side rib surface 1-2 of the limiting wedge plate 1 is in contact with the side rib end surface of the standard formwork 3 directly connected to the universal plate 4. The remaining easily detachable units are composed of standard wedge plates 1. The number and setting position of the limiting wedge plates 1 are determined according to needs. The limiting wedge plates 1 can effectively limit the movement of the standard formwork 3 to the inside, thereby ensuring the molding quality of the building concrete surface.

[0073] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments may still be modified, or some or all of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
