Description

Technical Field

[0001] This utility model relates to the technical field of building waterproofing equipment, and in particular to a waterproofing device for concrete pouring joints. Background Technology

[0002] In the process of large-area concrete pouring, a segmented pouring method is generally adopted. However, when subsequent pouring work is carried out, the previously poured concrete has dried and shrunk. At this time, the concrete poured before and after cannot be joined and fused together, thus forming a pouring joint between the two pours. The pouring joint is a potential water seepage channel in the concrete structure. If not handled properly, moisture may seep into the structure through the gap, leading to water damage and mold, and affecting the service life of the building.

[0003] Current methods for treating concrete pouring joints generally include cleaning the pouring joint surface, grouting, filling with joint sealant, or applying waterproof coating. However, these methods either treat the pouring joint during or after its formation, which can easily lead to incomplete treatment and water seepage. Using waterstops to protect the pouring joint before pouring is also an option, but the effect is unsatisfactory and water seepage can still occur. Therefore, a device capable of protecting concrete pouring joints is needed. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems and provide a waterproofing device for concrete pouring joints.

[0005] The technical solution of this utility model is: a waterproof device for concrete pouring joints, including a water-stop steel plate; the water-stop steel plate is a long groove type, including a base plate and two side plates respectively connected to the two long sides of the base plate; the base plate of the water-stop steel plate is horizontally connected to the pouring joint, and the two side plates are symmetrical about the center face of the base plate; the two side plates extend upwards on their respective sides, forming an angle with the base plate. The cross-section of the water-stop steel plate is an inverted trapezoid, the base plate is placed on the bottom surface of the pouring, and the two side plates extend outwards. After the concrete is poured and fixed, it can prevent water from easily entering the interior of the water-stop steel plate, thereby achieving the effect of waterproofing at the concrete pouring joint.

[0006] Preferably, reinforcing mesh is provided on both sides of the waterstop steel plate, with the height of the mesh exceeding the thickness of the waterstop steel plate. This allows the concrete to flow to the bottom slab during pouring and integrate with the concrete outside the waterstop steel plate, avoiding more pouring joints and thus ensuring the water-stopping performance of the waterstop steel plate.

[0007] Preferably, a vertical support is fixed to the waterstop steel plate; the vertical support includes horizontal bars arranged side by side, with several vertical bars evenly spaced between the two horizontal bars, and a partition net is provided between the vertical bars and the longitudinal bars; the bottom of the vertical support is fixed to the center surface of the base plate. The vertical support helps the poured concrete form a boundary for a single pour at the pouring joint, and creates a roughened state on the pouring boundary, which is beneficial to improving the bonding between the concrete on both sides and increasing the strength at the pouring joint.

[0008] Furthermore, the height of the waterstop steel plate is 2 / 3 of the height of the reinforcing mesh. This ensures the height of the waterstop steel plate while also providing sufficient thickness for the concrete above it, thus guaranteeing the concrete's strength.

[0009] Preferably, the width of the base plate is twice the height of the waterstop steel plate. The vertical support is set in the middle of the base plate, and the sufficient width of the base plate can ensure that the vertical support is fully covered by concrete after pouring, thereby enhancing the stability of the structure after pouring.

[0010] Preferably, the angle between the side plate and the horizontal direction is α, where 50°≤α≤90°. When the inclination angle of the side plate is too small, the concrete will not flow easily to the position between the side plate and the bottom surface of the pouring, resulting in a reduction in the strength of the concrete after pouring and affecting the safety of the building.

[0011] Preferably, the water-stop steel plate is a thin plate, with its side plates and bottom plate integrally formed. This avoids gaps between the side plates and bottom plate caused by welding, which could lead to water seepage.

[0012] The beneficial effects of this utility model are as follows: The waterproof device for concrete pouring joints of this utility model has the following advantages:

[0013] 1. The cross-section of the waterstop steel plate is an inverted trapezoid. The bottom plate is placed on the bottom surface of the concrete pouring, and the two side plates extend outward. After the concrete is poured and fixed, it can prevent water from easily entering the interior of the waterstop steel plate, thereby achieving the effect of waterproofing at the concrete pouring joint.

[0014] 2. The vertical support set in the middle of the waterstop steel plate can prevent the formation of the boundary of the primary pouring and can form a roughened structure on the boundary surface of the primary pouring, which is conducive to improving the bonding force between the concrete on both sides of the pouring joint and improving the firmness of the pouring joint surface.

[0022] Example 1: See Figure 1-6 A waterproofing device for concrete pouring joints includes a water-stop steel plate 1. The water-stop steel plate 1 is elongated and includes a base plate 11 and two side plates 12 connected to the two long sides of the base plate 11. The base plate 11 is horizontally connected to the pouring joint, and the two side plates 12 are symmetrical about the center face of the base plate 11. The two side plates 12 extend upwards on their respective sides, forming an angle with the base plate 11. The cross-section of the water-stop steel plate 1 is an inverted trapezoid. The base plate 11 is placed on the bottom surface of the pouring concrete, and the two side plates 12 extend outwards. After the concrete is poured and fixed, it prevents water from easily entering the interior of the water-stop steel plate 1, thereby achieving the effect of waterproofing the concrete pouring joint.

[0023] A steel mesh 01 is provided on both sides of the waterstop steel plate 1, and the height of the steel mesh 01 is greater than the thickness of the waterstop steel plate 1. This allows the concrete to flow onto the bottom slab 11 during pouring and to connect with the concrete outside the waterstop steel plate 1, avoiding more pouring joints and thus ensuring the waterstop performance of the waterstop steel plate 1.

[0024] A vertical support 2 is fixed on the water-stop steel plate 1. The vertical support 2 includes horizontal bars arranged side by side, with several vertical bars spaced equally between the two horizontal bars. A partition net is provided between the vertical bars and the longitudinal bars. The bottom of the vertical support 2 is fixed to the center surface of the base plate 11. The vertical support 2 helps the poured concrete form a boundary for a single pour at the pouring joint, and creates a roughened state on the pouring boundary, which is beneficial to improving the bonding between the concrete on both sides and increasing the strength of the pouring joint.

[0025] The height of the waterstop steel plate 1 is 2 / 3 of the height of the reinforcing mesh 01. This ensures the height of the waterstop steel plate 1 while also providing sufficient thickness for the concrete above it, thus guaranteeing the strength of the concrete.

[0026] The width of the base plate 11 is twice the height of the waterstop steel plate 1. The vertical support 2 is set in the middle of the base plate 11. The sufficient width of the base plate 11 can ensure that the vertical support 2 is fully covered by concrete after pouring, thereby enhancing the stability of the structure after pouring.

[0027] The angle between the side plate 12 and the horizontal direction is α, where 50°≤α≤90°. When the inclination angle of the side plate 12 is too small, the concrete will not flow easily to the position between the side plate 12 and the bottom surface 00, which will reduce the strength of the concrete 3 after pouring and affect the safety of the building.

[0028] The water-stop steel plate 1 is a thin plate, and its side plate 12 and bottom plate 11 are integrally formed. This avoids gaps between the side plate 12 and the bottom plate 11 caused by welding, which could lead to water seepage.

[0029] The bottom of the vertical support 2 is flush with the upper surface of the concrete to be poured.

[0030] The usage process of this embodiment includes the following steps:

[0031] ① Lay steel mesh 01 in the areas to be poured, and place water-stop steel plate 1 at the junction of the two areas;

[0032] ② Fix the waterstop steel plate 1;

[0033] ③ Pour concrete into a certain area, pour the concrete onto the waterstop steel plate 1, and vibrate the poured concrete.

[0034] ④ Pour concrete on the area on the other side of the waterstop steel plate 1, pour the concrete onto the waterstop steel plate 1, and vibrate the poured concrete so that the concrete poured twice can simultaneously wrap the vertical support 2.

[0035] ⑤ The installation of the device is complete after the concrete has dried completely.

[0036] Example 2: Example 2 is basically the same as Example 1, and the similarities will not be repeated. The difference is that the side plates 12 of the waterstop steel plate 1 are welded to the steel mesh 01 on both sides. This can prevent the waterstop steel plate 1 from slipping or floating during the pouring process.
