Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a column root pre-roughening device. Background Art

[0002] Usually in cast-in-place structures, after the cast-in-place slab is poured, it is necessary to chisel the surface before pouring the next layer of columns and walls. This allows the concrete to bond firmly. During construction, the concrete pavement layer is required to reach the designed concrete strength, and the surface is flat, clean, and free of pollution, impurities, oil stains, dust, etc. First, use a chiseling machine to chisel the surface of the paved concrete to remove the floating slurry and debris on the surface, then use a rotating wire brush to clean it, and then use a blower or vacuum cleaner to remove floating dust and fine particles, rinse it with a high-pressure water gun, and after it is dry, the next process can be constructed.

[0003] Under normal circumstances, it is necessary to manually use an electric pick or other tools to create a rough surface on the concrete surface to increase the cement contact area, which is time-consuming and labor-intensive and increases the difficulty of construction. Sometimes the column cross-section is too large and the electric pick is not long enough to even roughen it. Utility Model Content

[0004] The purpose of the utility model is to overcome the defects of the prior art and provide a column root pre-roughening device. Before the initial setting of concrete, the pointed head on the base plate is set at a predetermined construction position of the structural column, so that the concrete forms a rough surface after solidification, which is convenient for the subsequent construction of the structural column.

[0005] The technical solution to achieve the above purpose is a column root pre-roughening device, which is characterized by comprising:

[0006] A bottom plate, a side portion of which is formed with an inserting slot, and the inserting slot is arranged along the length direction of the bottom plate;

[0007] an ear plate slidably arranged in the plug-in slot, the ear plate is formed with a plug-in block corresponding to the plug-in slot, and the plug-in block is slidably adjusted in the plug-in slot; and

[0008] A plurality of pointed tips are laid on the surface of the base plate.

[0009] Furthermore, the ear plates are provided in plurality, and the distance between two adjacent ear plates located on the same side is determined by the spacing distance between the column reinforcements in the poured concrete.

[0010] Furthermore, a through hole is formed on the ear plate.

[0011] Furthermore, the bottom plate is made of soft material.

[0012] Furthermore, the pointed tip is made of soft material.

[0013] Furthermore, the size of the base plate is determined according to the size of the cast structural column.

[0014] Furthermore, the arrangement density of the pointed tips is determined according to the construction requirements on site.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] Before the initial setting of the concrete, the pointed head on the bottom plate is set at a predetermined construction position of the structural column, so that the concrete forms a rough surface after solidification, which is convenient for the subsequent construction of the structural column.

[0023] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] See also Figure 1 A column root pre-roughening device comprises: a base plate 3; and a plurality of pointed heads 1 laid on the surface of the base plate 3.

[0025] In the utility model, a preferred implementation is: after the structural floor is cast and before the concrete of the structural floor is initially set, the base plate 3 is placed in the structural floor and arranged corresponding to the predetermined setting position of the structural column, and the pointed head 1 on the base plate 3 is buried in the concrete. After the concrete is completed, the base plate 3 is removed so that the structural floor forms a rough surface corresponding to the position of the structural column. Preferably, the pointed head and the base plate are integrally formed.

[0026] Furthermore, a slidably adjustable ear plate 2 is provided on the side of the base plate 3. The base plate 3 is positioned and fixed on the structural floor through the ear plate 2, and the predetermined setting position of the structural column is positioned by placing the ear plate 2 at the column reinforcement position of the structural floor.

[0027] Furthermore, a plug-in slot is formed on the side of the bottom plate 3, and the plug-in slot is arranged along the length direction of the bottom plate 3. The ear plate 2 is formed with a plug-in block corresponding to the plug-in slot, and the plug-in block is slidably adjusted in the plug-in slot. By slidingly adjusting the ear plate 2, the position of the ear plate 2 can be adjusted according to the construction conditions on site so that the position of the ear plate 2 matches the position of the column reinforcement.

[0028] Furthermore, the ear plates 2 are provided in plurality, and the distance between two adjacent ear plates 2 located on the same side is determined by the spacing distance between the column reinforcements in the poured concrete.

[0029] Furthermore, a hole is formed on the ear plate 2 .

[0030] Furthermore, the bottom plate 3 is made of soft material.

[0031] Furthermore, the pointed tip 1 is made of a soft material. By making the bottom plate 3 and the pointed tip 1 of soft materials, it is convenient for users to store the bottom plate 3 and the pointed tip 1 by rolling or folding them when the bottom plate 3 is not in use, so as to reduce the space occupied by the bottom plate 3, thereby making the bottom plate 3 convenient to store and carry.

[0032] Furthermore, the size of the base plate 3 is determined according to the size of the cast structural column.

[0033] Furthermore, the arrangement density of the pointed tips 1 is determined according to the construction requirements on site.

[0034] The following is a description of the use of the column root pre-roughening device of the utility model.
