Description

Technical Field

[0001] The utility model relates to a roughening-free mould product in the technical field of concrete pouring. Background Art

[0002] During construction, in order to achieve the rough surface effect, large equipment such as chiseling machines and milling machines are generally used. The mechanical impact force during the use of machinery will damage the structure of the building layer, leaving hidden dangers to the quality of the project. Some construction sites have limited space and cannot be chiseled mechanically. Manual chiseling is time-consuming and labor-intensive, and the efficiency is relatively low, which increases the difficulty of construction. Therefore, a chiseling-free grouting tape has appeared in the existing technology. However, the structure of this chiseling-free grouting tape is too simple. After use, the interface between the new and old concrete is prone to problems such as air holes, resulting in insufficient internal fusion and unstable quality. Utility Model Content

[0003] The purpose of the utility model is to provide a roughening-free mold product for concrete molding. After molding, the internal fusion of new and old concrete is stronger, the quality is stable and reliable, the safety of the overall main structure is improved, zero damage to the structure, and the service life cycle of the structure is extended.

[0004] To achieve the above purpose, the utility model provides a roughening-free mold product for concrete molding, including a base plate, wherein a plurality of rows of large rough molding structures are arranged on the upper surface of the base plate, and small rough molding structures are arranged between each row of large rough molding structures.

[0005] Compared with the prior art, the beneficial effect of the present invention is that when pouring concrete, the roughening-free mold product can be fixed to the template by binding, snapping or fitting, or it can be directly formed integrally with the template. Through the cooperation of the large rough molding structure and the small rough molding structure, the contact area between the new and old concrete is effectively expanded. After molding, the internal fusion of the new and old concrete is stronger and the quality is stable and reliable. It can also play a leak-proof role when used with the template, which can improve the safety of the overall main structure, cause zero damage to the structure, and extend the service life cycle of the structure.

[0006] As a further improvement of the present invention, the large rough forming structure and the small rough forming structure are regular three-dimensional structures or irregular three-dimensional structures.

[0007] In this way, the bonding strength between new and old concrete can be further improved by coordinating different regular three-dimensional structures or irregular three-dimensional structures.

[0008] As a further improvement of the present invention, the large rough forming structure is an inverted triangle tooth.

[0009] In this way, the inverted triangular teeth set at intervals make the internal fusion of new and old concrete stronger and the quality stable and reliable.

[0010] As a further improvement of the present application, the small rough forming structure comprises two rows of small teeth, the height of the small teeth is lower than that of the inverted triangular teeth, one row of small teeth is close to the slope bottom edge of the adjacent inverted triangular tooth in the same row, and the other row of small teeth is close to the vertical surface of the other adjacent inverted triangular tooth in the same row and a gap is left between the two.

[0011] In this way, the two rows of small teeth are close to the two adjacent inverted triangular teeth respectively, so that a height difference is formed between the inverted triangular teeth and the small teeth, and the contact area of the new and old concrete is increased, thereby further improving the stability of the internal fusion of the new and old concrete.

[0012] As a further improvement of the present application, a row of small sharp teeth is arranged between the two rows of small teeth, and the height of the small sharp teeth is lower than that of the small teeth.

[0013] In this way, the small teeth and the small sharp teeth form a height difference again, and the contact area of the new and old concrete is increased, so that the bonding surface of the new and old concrete between the small teeth is more solid and reliable.

[0014] As a further improvement of the present application, the small teeth are square teeth; in this way, the square teeth and the inverted triangular teeth are two different shapes, one is blunt and the other is sharp, so that the two are better matched to improve the bonding firmness between the new and old concrete.

[0015] As a further improvement of the present application, the two adjacent rows of inverted triangular teeth are arranged in a staggered manner; in this way, the staggered distribution can improve the occlusion of the bonding surface of the new and old concrete, thereby improving the bonding firmness of the two.

[0016] As a further improvement of the present application, the planar area occupied by the large rough forming structure and the small rough forming structure is the same.

[0017] In this way, the bonding surface of the new and old concrete is more regular, the appearance after forming is more beautiful, and the difficulty of final demolding caused by the different sizes of the contact surface can be avoided. BRIEF DESCRIPTION OF DRAWINGS

[0018] Figure 1 The present application is a schematic diagram of the structure.

[0019] Figure 2 is Figure 1 The local enlarged view of A in the middle.

[0020] Among them, 1 inverted triangular tooth, 2 small tooth, 3 small sharp tooth, 4 bottom plate. DETAILED DESCRIPTION

[0021] The present application will be further described below in conjunction with the drawings:

[0022] AsFigures 1-2 The illustrated non-chasing mold product for concrete forming includes a bottom plate 4, and the upper surface of the bottom plate 4 is provided with a plurality of rows of large rough forming structures, and small rough forming structures are arranged between each row of large rough forming structures. The large rough forming structures and the small rough forming structures are regular solid structures or irregular solid structures.

[0023] The large rough forming structure is an inverted triangular tooth 1. The small rough forming structure includes two rows of small vertical teeth 2, and the height of the small vertical teeth 2 is lower than that of the inverted triangular tooth 1. One row of the small vertical teeth 2 is close to the oblique face bottom edge of the adjacent inverted triangular tooth 1 in the same row, and the other row of the small vertical teeth 2 is close to the vertical face of the other adjacent inverted triangular tooth 1 in the same row, and a gap is left between the two rows.

[0024] A row of small sharp teeth 3 is arranged between the two rows of small vertical teeth 2, and the height of the small sharp teeth 3 is lower than that of the small vertical teeth 2. The small vertical teeth 2 are square teeth. The two adjacent rows of inverted triangular teeth 1 are arranged in a staggered manner. The large rough forming structure and the small rough forming structure occupy the same planar area.

[0025] In the utility model, a plurality of rows of inverted triangular teeth 1 are processed on the bottom plate 4, two rows of small vertical teeth 2 are arranged between each row of inverted triangular teeth 1, small sharp teeth 3 are arranged between the small vertical teeth 2, and the two adjacent rows of inverted triangular teeth 1 are arranged in a staggered manner.

[0026] When pouring concrete, the non-chasing mold product can be fixed to the formwork by binding, buckling or pasting, or can be directly integrally formed with the formwork. When in use, the non-chasing mold product should not be removed too early or too late. The non-chasing mold product should be removed within 36 to 48 hours after pouring concrete. If the non-chasing mold product is removed too early, surface concrete will fall off, and if the non-chasing mold product is removed too late, the non-chasing mold product will be difficult to remove,

[0027] The inverted triangular tooth 1 and the small vertical tooth 2 are combined, and the small vertical tooth 2 and the small sharp tooth 3 structure (which can also be a combination of other different shapes of regular solid structures or irregular solid structures) are combined, which effectively expands the contact area of new and old concrete, and the internal fusion of new and old concrete after forming is more solid, stable and reliable in quality. In combination with the formwork, the non-chasing mold product can also play a role in preventing leakage. The safety of the overall main structure can be improved, the structure is not damaged, and the service life of the structure is prolonged. The working efficiency is effectively improved, the construction period is shortened, the maintenance workload during the operation stage is greatly reduced, and the service life of the structure is improved. The formed structure is regular and beautiful in appearance, easy to install, reusable, and can be made into various sizes according to the needs of the site. Compared with the process of mechanical chasing, the amount of dust generated is greatly reduced, the installation and construction environment is greatly improved, the installation efficiency is improved, the construction period is shortened, and the maintenance workload during the operation stage is greatly reduced.
