Description

Technical Field

[0001] The utility model particularly relates to a concrete sleeper free-of-cut wood formwork. Background Art

[0002] The wooden formwork for concrete sleepers is a formwork made of wooden boards or wood, which can shape the shape and size of components during the concrete pouring process. The wooden formwork can be a single wooden board or a complex structure made up of multiple wooden boards, depending on the shape and size of the components to be poured. At present, after the concrete is poured, a series of indentations or rough surfaces are chiseled out on the surface of the hardened concrete by using special tools such as "axes", that is, the surface of the concrete is roughened, which can increase the bonding strength of the new and old concrete interfaces, improve the integrity and durability of the structure, and enable better bonding between the new and old concrete, thereby improving the bearing capacity and shear strength of the structure. In view of this, by fixing a layer of textured grouting tape on the inner side of the wooden formwork, the concrete sleeper can form an uneven splicing surface after pouring, and no manual roughening is required after demoulding, which greatly improves construction efficiency.

[0003] However, in actual use of existing chiseling-free wooden formwork, the stop strip and the board body are usually fixed by bolts or glue. In the bolt connection method, a large number of bolts are needed to ensure that the stop strip fits the board body during installation, and the installation process is relatively troublesome. The glue method is often difficult to adhere firmly. When in use, the stop strip is easily fallen off due to the adsorption of concrete, affecting its use.

[0004] Therefore, it is necessary to invent a kind of concrete sleeper free from chiseling of rough wood formwork to solve the above problems. Utility Model Content

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] The utility model provides Figure 1-6 The concrete sleeper free wood formwork shown comprises a plate body 1, a grouting strip 2 provided on one side of the plate body 1, and an installation assembly 3;

[0033] The outer wall of the plate body 1 is provided with an annular groove 11 along its circumference, and the four sides of the plate body 1 away from the slurry-stopping belt 2 are provided with insertion holes 12;

[0034] The grout-stopping strip 2 includes a central strip 21, transition strips 22 connected to the four sides of the central strip 21, a positioning plate 23 connected to the transition strip 22, and a slot 24 opened on the positioning plate 23;

[0035] The mounting assembly 3 is used to lock the positioning plate 23 inserted into the annular groove 11, so that the plate body 1 and the mortar stop strip 2 are assembled into a main body of the free-cutting wood formwork;

[0036] The installation assembly 3 includes a cross plate 31 , plug plates 32 connected to the four ends of the cross plate 31 , and locking members 33 installed on the four ends of the cross plate 31 .

[0037] In one embodiment, the four insertion holes 12 and the four slots 24 are all square in shape and are respectively adapted to the corresponding insertion plates 32, so that the insertion plates 32 can pass through the insertion holes 12 and into the slots 24 to fix the positioning plate 23, and then complete the fixation of the stop strip 2. The locking member 33 is set as a hexagon socket bolt, so that after the locking member 33 is screwed in, the outer side of the cross plate 31 is flat as a whole, which is convenient for the staff to use, and the plate body 1 and the cross plate 31 are both provided with threaded holes 34 for screwing in the locking member 33, so that the cross plate 31 only needs to be fixed to the plate body 1 and the stop strip 2 by four hexagon socket bolts, thereby completing the assembly of the free-cutting wood formwork, wherein the cross plate 31 is also provided with a receiving hole 35 for accommodating the end of the locking member 33 at the threaded hole 34, ensuring that the outer side of the cross plate 31 is flat as a whole, which is convenient for the staff to use.

[0038] In one embodiment, the transition zone 22 and the center zone 21 are integrally formed, and the outer side surface of the center zone 21 is set as an uneven corrugated surface, so that the concrete sleeper beam can form an uneven splicing surface after pouring, and no manual roughening is required after demolding, which greatly improves construction efficiency.

[0039] In one embodiment, the positioning plate 23 is adapted to the annular groove 11, and the slot 24 is arranged on a side surface away from the plate body 1 when the positioning plate 23 is unfolded, to ensure that after the positioning plate 23 is folded, the slot 24 can be aligned with the socket 12, thereby completing the assembly of the plate body 1 and the stop strip 2.

[0040] The specific implementation method is as follows: When assembling the present invention, the staff fits the stop tape 2 on the side of the plate body 1 away from the threaded hole 34, aligns the center tape 21 with the side of the plate body 1, and then folds the four transition tapes 22 in sequence so that the transition tapes 22 are flipped and fit on the peripheral side walls of the plate body 1. At this time, the positioning plate 23 is synchronously flipped to the annular groove 11 as the transition tape 22 is flipped. The staff directly inserts the positioning plate 23 into the inside of the annular groove 11 so that the slot 24 on the positioning plate 23 is aligned with its adjacent socket 12;

[0041] Then the staff fits the cross plate 31 on the other side of the plate body 1, so that the inserting plates 32 at the ends of the cross plate 31 are respectively inserted into the corresponding insertion holes 12, and then inserted into the slots 24 of the positioning plates 23 corresponding to the insertion holes 12, so that the four positioning plates 23 cannot pop out in the annular groove 11, and the cross plate 31 is locked by the locking member 33, tightly attached to the side wall of the plate body 1, so that the position of the positioning plate 23 is fixed by the inserting plate 32, and further the position of the center belt 21 remains stationary, that is, the assembly of the mortar stop strip 2 and the plate body 1 is completed, forming the main body of the non-chisel wood formwork for use;

[0042] Specifically, when the main body of the free-cutting wooden formwork is in use, the center belt 21 can be fitted with the poured concrete, so that after the concrete solidifies, an uneven joint surface can be formed without artificial cutting, which greatly improves labor efficiency and greatly speeds up the production speed of concrete sleepers. Moreover, the free-cutting wooden formwork can be recycled after demoulding, which is convenient for construction and improves the utilization rate of materials. Moreover, under the limitation of the inserting plate 32, the grouting belt 2 is firmly connected to the plate body 1, and the center belt 21 will not deviate and is not easy to fall off, so that the quality of the finished product of the concrete sleeper is greatly improved.

[0043] This embodiment specifically solves the problem that the current chiseling-free wooden formwork in the prior art is usually fixed to the board body 1 by bolts or glue during actual use. In the bolt connection method, a large number of bolts are needed to ensure that the grouting strip 2 fits the board body 1 during installation, and the installation process is relatively troublesome. The gluing method is often difficult to adhere firmly. When in use, the grouting strip 2 is easily fallen off due to the adsorption of concrete, which affects the use.

[0044] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
