Abstract
Description
Technical Field
[0001] This application relates to the technical field of building boards, and particularly relates to a cast-in-place concrete formwork with imitation wood grain finish. Background Art
[0002] Nowadays, in order to make cities more beautiful, there are more and more landscape projects in cities, and the appearances of landscape projects also show various styles. Cast-in-place concrete with imitation wood grain finish is also a kind of landscape project, and its application is increasing. Currently, the assembly and processing of formwork for imitation wood grain finish are basically blank. The formwork also directly nails the untreated wood grain formwork to the backing board according to the conventional method, and the joints between two formworks are not treated either. As a result, the wood grain texture of the cast concrete cannot achieve the purpose of clear texture, and there are nail marks; after the formwork is removed, the joints are chipped and corner - broken, resulting in the non - straight and non - beautiful joint concrete.
[0003] Therefore, this application provides a cast-in-place concrete formwork with imitation wood grain finish to ensure clear wood grain texture after the imitation wood grain concrete is cast. Utility Model Content
[0004] The purpose of this application is to solve the problems existing in the prior art, and to propose a cast-in-place concrete formwork with imitation wood grain finish.
[0005] To achieve the above purpose, this application adopts the following technical solutions:
[0006] A cast-in-place concrete formwork with imitation wood grain finish, including a backing board, on which a number of wood grain formworks are evenly distributed. One side of the wood grain formwork is provided with a groove and the other side is provided with a protrusion along the length direction. Two adjacent wood grain formworks along the length direction are sequentially inserted with staggered joints through the protrusion and the groove.
[0007] Preferably, the wood grain formworks have two types with different widths, and the two wood grain formworks with different widths are inserted with staggered joints along the length direction.
[0008] Preferably, two adjacent wood grain formworks along the length direction are inserted along the center line.
[0009] Preferably, slots are provided at the centers of both the protrusion and the groove, and a plug board is commonly inserted into the slots of adjacent protrusions and grooves.
[0010] Preferably, the slot on the protrusion penetrates through the protrusion, and the slot at the groove is capped at the upper end and open at the lower end.
[0011] Preferably, the cross - sections of both the protrusion and the groove are isosceles trapezoids, and shoulders are provided on both the upper and lower sides of the bottom edges of the protrusion and the groove.
[0012] Preferably, the backing board and the wood grain formwork are obliquely shot - connected by a nail from the bottom end of the backing board.
[0013] Preferably, it also includes edge sealing that cooperates with the wood grain templates at both ends.
[0014] Compared with the prior art, the present application provides a cast-in-place concrete formwork with imitation wood grain finish, having the following beneficial effects:
[0015] 1. During use, lay the lining board flat, first place a row of side-by-side wood grain templates in the direction of the bottom layer of the lining board, and fix this row of wood grain templates on the lining board through fasteners. Then, successively insert the wood grain templates in the way that the protrusions are inserted into the grooves. For each inserted wood grain template, fix it with fasteners until the top is sealed. Compared with only nailing, this solution connects by the way of inserting protrusions into grooves, increasing the contact bearing area of the filter plate, making the connection between the wood grain templates along the length direction closer and improving the connection strength; at the same time, it also avoids the extrusion and chipping at the joints of the wood grain templates.
[0016] 2. The adjacent wood grain templates are distributed in a staggered manner, enabling the wood grain templates in the length direction to be treated with staggered joints, preventing the occurrence of through joints, and thus improving the overall strength of the formwork. The staggered treatment during installation also reduces the steps and corresponding costs for rework on the appearance of the concrete in the later stage.
[0017] Other advantages, objectives, and features of the present application will be described to some extent in the subsequent specification; and to some extent, based on the study of the following text, they will be obvious to those skilled in the art; or, they can be learned from the practice of the present application.

[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the attached Figures 1-9 drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.
[0029] To solve the problems existing in the prior art, this embodiment provides a cast-in-place wood-grain decorative concrete formwork, including a lining board 1, on which a plurality of wood grain templates 2 are evenly distributed. A groove 6 is provided on one side of the wood grain template 2 along the length direction, and a protrusion 5 is provided on the other side. Two adjacent wood grain templates 2 along the length direction are sequentially inserted and staggered through the protrusion 5 and the groove 6.
[0030] Details of the principle of this embodiment:
[0031] A cast-in-place wood-grain decorative concrete formwork includes a lining board 1, on which a plurality of wood grain templates 2 are evenly distributed. The wood grain templates 2 are fixed on the lining board 1 by fasteners. The wood grain templates 2 are made of wood with fewer tree knots and clear wood grain texture after processing. The texture depth is 1 mm to ensure clear wood grain. After the original wood board is cut, it is subjected to wire drawing, drying, carbonization, and painting treatments to improve the strength of the wood grain template 2 and increase the service life of the wood grain template 2.
[0032] A groove 6 is provided on one side of the wood grain template 2 along the length direction, and a protrusion 5 is provided on the other side. Two adjacent wood grain templates 2 along the length direction are sequentially inserted through the protrusion 5 and the groove 6, and the two wood grain templates 2 along the length direction are staggered, so that the wood grain templates 2 are staggered along the length direction on the lining board 1.
[0033] During use, lay the lining board 1 flat. First, place a row of side-by-side wood grain templates 2 in the bottom direction of the lining board 1, and fix this row of wood grain templates 2 to the lining board 1 through fasteners. The ends of the raised parts 5 of this row of wood grain templates 2 face the same direction and are at the same horizontal plane. Then, insert the wood grain templates 2 in sequence. Each time a wood grain template 2 is inserted, it is fixed through fasteners until the top is sealed. Compared with only nailing, this solution connects through the insertion of the raised parts 5 and the grooves 6, increasing the contact bearing area, making the connection between the wood grain templates 2 along the length direction tighter and improving the connection strength. At the same time, it also avoids the extrusion and corner chipping at the joints of the wood grain templates 2. And the adjacent wood grain templates 2 are distributed in a staggered manner, making the wood grain templates 2 in the length direction undergo staggered joint treatment to prevent the occurrence of continuous joints. Because a building with continuous joints can only bear the pressure coming from the direction perpendicular to the continuous joints, and its bearing capacity for the force parallel to the continuous joints is low. Thus, the overall strength of the template is improved. The staggered treatment during installation reduces the steps and corresponding costs for rework on the appearance of the concrete in the later stage.
[0034] To ensure the pouring effect at the joint, a 2-mm-deep joint is reserved at the joint of two wood grain templates 2.
[0035] In a further embodiment of this solution, the wood grain templates 2 have two types with different widths, and the two wood grain templates 2 with different widths are inserted in a staggered manner along the length direction.
[0036] Details of the principle of this embodiment:
[0037] The two widths of the wood grain templates 2 are 8 cm and 12 cm respectively. Refer to the attached Figure 1 As shown, the two wood grain templates 2 with different widths are spliced in a staggered manner. Only a slight shift can achieve the staggered joint treatment to avoid continuous joints. The difficulty of staggered joints is reduced.
[0038] The maximum processing length of the wood grain template 2 is 4 m, and the shortest size is cut on-site according to requirements, with a thickness of 2 cm. This avoids breakage due to excessive length.
[0039] In a further embodiment of this solution, refer to the attached Figure 9 As shown, two adjacent wood grain templates 2 along the length direction are inserted along the center line. In this way, as long as the wood grain templates 2 with different widths are installed crosswise, the staggered joint treatment can be ensured, and the staggered joints are regular and more beautiful.
[0040] In a further embodiment of this solution, slots 7 are provided at the centers of both the raised parts 5 and the grooves 6, and a plug board 8 is commonly inserted into the slots 7 of the adjacent raised parts 5 and grooves 6. The ports of the slots 7 are chamfered.
[0041] During use, after the lower wood grain template 2 is fixed, first insert the insertion plate 8 into the slot 7 on the protrusion 5, and then align the slot 7 at the groove 6 of another wood grain template 2 with the insertion plate 8, and then move down this wood grain template 2 to complete the centered insertion of two adjacent wood grain templates 2. And through the restriction of the insertion plate 8, after the two adjacent wood grain templates 2 are inserted, they always maintain a stable state and will not shift sideways, ensuring the neatness of the upper and lower staggered joints. The setting of the insertion plate 8 not only improves the centered alignment speed of adjacent wood grain templates 2, improves the installation efficiency, but also improves the connection strength.
[0042] In a further embodiment of this solution, the slot 7 on the protrusion 5 penetrates through the protrusion 5, and the upper end of the slot 7 at the groove 6 is capped and the lower end is open. This makes the insertion plate 8 hidden and not exposed after installation, avoiding the appearance of extra gaps and affecting the overall aesthetics.
[0043] In a further embodiment of this solution, the cross-sections of the protrusion 5 and the groove 6 are both isosceles trapezoids, with regular shapes, reducing the collision and damage during insertion. Both the upper and lower sides of the bottom edges of the protrusion 5 and the groove 6 are provided with shoulders. This avoids the appearance of sharp edges that are easily damaged by knocking.
[0044] In a further embodiment of this solution, the lining plate 1 and the wood grain template 2 are connected by a nail 3, and the nail 3 is obliquely shot from the bottom end of the lining plate 1. It is shot from the bottom end of the lining plate 1 and does not penetrate through the end face of the wood grain template 2. The bottom end of the lining plate 1 is the installation base surface, so the nail mark is hidden, improving the aesthetics; compared with direct shooting, the oblique shooting of the nail can increase the connection strength between the wood grain template 2 and the lining plate 1.
[0045] In a further embodiment of this solution, it further includes a sealing edge 4 that cooperates with the wood grain templates 2 at both ends. Refer to the attached Figure 2 As shown, sealing edges 4 are provided at both ends of the lining plate 1. The end face of the bottom sealing edge 4 is provided with a convex block that cooperates with the groove 6, and the end face of the top sealing edge 4 is provided with an installation groove that cooperates with the protrusion 5. Through the setting of the two sealing edges 4, the grooves 6 and protrusions 5 of the wood grain templates 2 at both ends are received and protected, and at the same time, it also avoids the protrusion 5 leaking out and affecting the aesthetics.

Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and application concept of the present application, makes equivalent substitutions or changes, and should be covered within the protection scope of the present application.
