Description

Technical Field

[0001] This utility model relates to the field of auxiliary devices for building construction, and in particular to a column base rubber sleeve for preventing grout leakage in wooden formwork of building engineering. Background Technology

[0002] In the construction of concrete columns in small-scale building projects, wooden formwork is widely used due to on-site construction conditions and economic considerations. However, wooden formwork is prone to grout leakage at the column base. This not only leads to concrete waste but may also affect the appearance quality and structural strength of the concrete column. Traditional grout leakage prevention measures mostly involve filling the bottom of the formwork with mortar or square timber to seal the edges, preventing concrete from leaking out through the gap between the base and the ground during pouring. This is not only cumbersome to operate, but the sealing mortar can also easily penetrate into the wall and column construction line, causing uneven, jagged mortar protrusions of 5-30mm, posing a potential quality hazard to the load-bearing safety of the wall and column structure. It also results in an unnecessary increase in construction costs and waste of resources.

[0003] While it can reduce concrete leakage to some extent, it cannot completely eliminate grout leakage. Furthermore, after the concrete in the walls and columns has solidified, the sponge strips are prone to deformation due to the vibration, and their outer side is covered by concrete grout. This requires secondary chiseling, which leads to material waste, consumes a lot of manpower and time, and seriously affects the construction progress and economic benefits. Utility Model Content

[0004] The purpose of this utility model is to provide a column base rubber sleeve for preventing grout leakage in wooden formwork of building engineering, so as to solve the problem of grout leakage in existing wooden formwork column bases and improve the pouring quality and construction efficiency of concrete columns.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A column base rubber sleeve for preventing grout leakage in wooden formwork of construction engineering. The main body of the column base rubber sleeve is L-shaped, and its inner side wall is provided with several anti-slip protrusions, which are regularly arranged along the axial direction of the rubber sleeve body. The column base rubber sleeve is composed of an inner leak-proof flange and an outer leak-proof flange. Both the inner and outer leak-proof flanges are L-shaped structures that match the four corners of the formwork. The outer leak-proof flange is fitted outside the inner leak-proof flange, and there is a cavity between the inner and outer leak-proof flanges for the installation and splicing of the formwork. The corner of the inner leak-proof flange has an outward protrusion, which connects the inner and outer leak-proof flanges into one piece and divides the cavity into two non-communicating, mutually perpendicular cavities.

[0007] The anti-slip protrusions are installed on the inner and outer leak-proof flanges and the contact surface of the template. The anti-slip protrusions are 1mm-2mm high and the spacing between adjacent anti-slip protrusions is 20-25mm. By increasing the friction, the rubber sleeve can be firmly attached to the template surface during concrete pouring, effectively preventing the rubber sleeve from shifting or loosening, thereby ensuring the stability and reliability of the leak-proof effect.

[0008] The spacing between the inner and outer leak-proof flanges is set according to the thickness of the template. The thickness of the inner and outer leak-proof flanges is 14mm-15mm, the height is 1500mm, and the width is 80mm.

[0009] This utility model proposes a column base rubber sleeve for preventing grout leakage from wooden formwork in building engineering. As a portable auxiliary material in the process of cast-in-place concrete construction, it has good elasticity, adhesion and weather resistance. It can effectively ensure the integrity and aesthetics of the building structure by preventing the leakage of building materials such as concrete and cement from the joints of the formwork during the pouring process.

[0010] This column base rubber sleeve maintains stable performance under high or low temperature conditions, and resists the erosion of chemicals in concrete, maintaining good sealing performance. Furthermore, this invention also has the following beneficial effects:

[0011] (1) Good anti-leakage effect: The unique "L"-shaped structure of the column base rubber sleeve and the double-layer anti-leakage flange design make it able to fit tightly with the formwork and form a tight closed seal at the four corners of the column, effectively preventing concrete grout from leaking from the formwork joints and the gap between the column base and the ground. This greatly reduces the risk of structural defects caused by grout leakage, avoids the extra cost and time consumption caused by rework and repair, and ensures that the quality of the building structure meets high standards.

[0012] (2) Improve construction efficiency: Using this utility model can simplify the construction process, reduce cleaning time, and improve construction efficiency.

[0013] (3) Protect the building structure: The column corner sleeve can prevent moisture and chemical substances from corroding the building structure and improve the service life of the building.

[0014] (4) High aesthetic appeal: The column base of the building after using this utility model has smooth and beautiful lines, which enhances the overall appearance of the building. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1-3 As shown, a column base rubber sleeve for preventing grout leakage in wooden formwork of construction engineering is provided. The column base rubber sleeve 4 has an L-shaped body with several anti-slip protrusions 3 on its inner side wall. The anti-slip protrusions 3 are regularly arranged along the axial direction of the rubber sleeve body. The column base rubber sleeve is composed of an inner anti-leakage flange 1 and an outer anti-leakage flange 2. Both the inner anti-leakage flange 1 and the outer anti-leakage flange 2 are L-shaped structures that match the four corners of the template 5. The outer anti-leakage flange is placed outside the inner anti-leakage flange. There is a cavity between the inner anti-leakage flange 1 and the outer anti-leakage flange 2 for the installation and splicing of the template. There is an outward protrusion at the corner of the inner anti-leakage flange. The protrusion connects the inner anti-leakage flange 1 and the outer anti-leakage flange 2 into one piece and divides the cavity into two mutually perpendicular cavities that are not connected to each other.

[0022] The anti-slip protrusions 3 are provided on the contact surfaces of the inner leak-proof flange 1, the outer leak-proof flange 2, and the template. The anti-slip protrusions are 1mm-2mm high, and the spacing between adjacent anti-slip protrusions is 20-25mm. By increasing the friction, the rubber sleeve can be firmly attached to the template surface during the concrete pouring process, effectively preventing the rubber sleeve from shifting or loosening, thereby ensuring the stability and reliability of the anti-leakage effect.

[0023] The spacing between the inner and outer leak-proof flanges is set according to the thickness of the template. The thickness of the inner and outer leak-proof flanges is 14mm-15mm, the height is 1500mm, and the width is 80mm.

[0024] When using the column base rubber sleeve, first install and fix it on one side of the formwork, ensuring the anti-slip protrusions are in close contact with the formwork. Then install the formwork on the other side, repeating this process in sequence. After all four sides of the formwork are connected, reinforce and correct the formwork. During the concrete pouring process, as the concrete gradually fills and the pressure gradually increases, the rubber sleeve and the formwork adhere more tightly under the combined action of the concrete pressure and the anti-slip protrusions of the rubber sleeve itself, forming a highly sealed anti-leakage system that effectively prevents concrete from seeping out from the column base, ensuring that the concrete column pouring quality meets the expected standards.

[0025] The specifications and dimensions of this utility model are for construction reference only. In actual use, they can be freely cut according to the height and direction of concrete pouring.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
