Abstract
Description
Technical Field
[0001] This application relates to the field of concrete waterproofing technology, and in particular to a protective structure and a shielding structure. Background Technology
[0002] Cracks often occur at the junction of vertical protrusions and horizontal concrete in cast-in-place concrete structures. This is mainly due to stress concentration and temperature changes, which can cause cracks at the junction of vertical protrusions and horizontal concrete, damaging the waterproof layer. Deformation at the junction of vertical protrusions and horizontal concrete can lead to sealing failure and openings at the joints, resulting in water leakage at the roof expansion joints.
[0003] In response to the above situation, the following technical solutions are currently mainly adopted. In the construction of expansion joints, the waterproof layer often needs to extend across the expansion joint to the wall of the high-span roof. Due to the inconsistent deformation of the roof on both sides of the high and low spans, the waterproof layer often opens or breaks at the termination due to the difference in settlement on both sides, forming a leakage path.

[0015] On the other hand, this application also provides a shielding structure, respectively disposed on a first wall and a second wall forming an expansion joint, wherein the height of the first wall is less than the height of the second wall, the shielding structure comprising: a first shielding component, vertically disposed on the upper surface of the first wall, the upper surface of the first wall being connected to the surface of the first wall forming the expansion joint; a second shielding component, one end disposed on the second wall, the other end extending toward the first wall, the projection of the second shielding component on the upper surface of the first wall covering the projection of the first shielding component on the upper surface of the first wall, and the projection of the second shielding component on the second wall facing the surface of the second shielding component overlapping the projection of the first shielding component on the second wall facing the surface of the second shielding component; the first shielding component is any of the above-mentioned first shielding component; the second shielding component is any of the above-mentioned second shielding component.
[0016] This application has at least the following technical advantages over the prior art:
[0017] 1. A protective structure is used to cover concrete expansion joints to prevent leakage. The concrete expansion joint is formed by a first wall and a second wall, the height of the first wall being less than the height of the second wall. An expansion joint exists between the surfaces of the first and second walls facing each other. The protective structure includes a sealing component disposed at the expansion joint.

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0026] Cracks often occur at the junction of vertical protrusions and horizontal concrete in cast-in-place concrete structures. This is mainly due to stress concentration and temperature changes, which can cause cracks at the junction of vertical protrusions and horizontal concrete, damaging the waterproof layer. Deformation at the junction of vertical protrusions and horizontal concrete can lead to sealing failure and openings at the joints, resulting in water leakage at the roof expansion joints.
[0027] In response to the above situation, the following technical solutions are currently mainly adopted. In the construction of expansion joints, the waterproof layer often needs to extend across the expansion joint to the wall of the high-span roof. Due to the inconsistent deformation of the roof on both sides of the high and low spans, the waterproof layer often opens or breaks at the termination due to the difference in settlement on both sides, forming a leakage path.
[0028] To address the aforementioned technical problems, this application provides a protective structure that can be installed on concrete walls of varying heights. The sealing effect between expansion joints will not be altered due to the deformation of the concrete walls, thus ensuring the continuity of the waterproofing effect on the expansion joints.
[0029] This application provides a protective structure; please refer to... Figures 1-4 As shown, the protective structure is used to shield the expansion joint k, which is formed by a first wall 1 and a second wall 2. The height of the first wall 1 is less than the height of the second wall 2. The expansion joint k is located between the surfaces of the first wall 1 and the second wall 2 facing each other. The protective structure includes: a sealing component 3, which is disposed in the expansion joint k; a first shielding component 4, which is disposed on the upper surface of the first wall 1 and is connected to the surface of the first wall 1 that forms the expansion joint k; and a second shielding component 5, which is disposed at one end in the second wall 2 and extends towards the first wall 1 at the other end. The projection of the second shielding component 5 on the upper surface of the first wall 1 covers the projection of the first shielding component 4 on the upper surface of the first wall 1. The projection of the second shielding component 5 onto the surface of the second wall 2 facing the second shielding component 5 overlaps with the projection of the first shielding component 4 onto the surface of the second wall 2 facing the second shielding component 5.
[0030] Specifically, the first shielding component 4 and the second shielding component 5 are respectively installed on the first wall 1 and the second wall 2 at different heights. The first wall 1 and the second wall 2 are both made of concrete. The first wall 1 and the second wall 2 are prone to cracking. This is mainly due to stress concentration and temperature changes, which can easily cause cracks between the first wall 1 and the second wall 2 and damage the waterproof layer between the first wall 1 and the second wall 2. Due to the deformation at the junction of the first wall 1 and the second wall 2, there are problems such as sealing failure and opening at the joint, which leads to water leakage at the roof expansion joint k. The protective structure in this application includes a first shielding component 4 and a second shielding component 5. The first shielding component 4 and the second shielding component 5 are not connected. The first shielding component 4 is disposed on the upper surface of the first wall 1, and the second shielding component 5 is disposed on the second wall 2. The projection of the second shielding component 5 on the upper surface of the first wall 1 covers the projection of the first shielding component 4 on the upper surface of the first wall 1. The projection of the second shielding component 5 on the surface of the second wall 2 facing the second shielding component 5 overlaps with the projection of the first shielding component 4 on the surface of the second wall 2 facing the second shielding component 5. This makes the first shielding component 4, the second shielding component 5, the upper surface of the first wall 1, and the surface of the second wall 2 facing the first shielding component 4 form a sealing structure. This sealing structure is used to shield the expansion joint k and prevent liquid from entering the expansion joint k. No matter how the first wall 1 and the second wall 2 deform, the expansion joint k will always be shielded.
[0031] In some optional embodiments, the protective structure further includes a polymer sealant layer 6 disposed between the first shielding member 4 and the upper surface of the first wall 1.
[0032] Specifically, the polymer sealant layer 6 not only ensures the sealing effect of the gap, but also provides the first wall 1 with expansion and contraction allowance, which can cope with the deformation of the gap between the first wall 1 and the second wall 2, and provide a gentle transition space for the deformation difference between the first wall 1 and the first shielding component 4.
[0033] In some alternative embodiments, the protective structure further includes a first waterproof layer 7, which extends from the surface of the first shielding member 4 facing away from the second wall 2 to the upper surface of the first wall 1.
[0034] Specifically, the first waterproof layer 7 is made of SBS modified bitumen waterproof membrane. The first waterproof layer 7 is applied to the surface of the first shielding component 4 facing away from the second wall 2, preventing the first shielding component 4 from rusting, extending its service life, and preventing external liquids from flowing into the expansion joint k, thus providing further protection for the expansion joint k. The first waterproof layer 7 is also applied to the upper surface of the first wall 1, protecting it from liquid penetration into the interior of the first wall 1 and improving its waterproof performance.
[0035] In some optional embodiments, the first waterproof layer 7 includes a first sub-waterproof layer 71 and a second sub-waterproof layer 72. The first sub-waterproof layer 71 covers the surface of the first shielding member 4 facing away from the second wall 2, and the second sub-waterproof layer 72 is disposed on the upper surface of the first wall 1, with an overlapping area between the first sub-waterproof layer 71 and the second sub-waterproof layer 72.
[0036] Specifically, the first waterproof layer 7 is divided into two parts: a first sub-waterproof layer 71 and a second sub-waterproof layer 72. The first sub-waterproof layer 71 is laid separately on the surface of the first shielding component 4 facing away from the second wall 2, and the second sub-waterproof layer 72 is laid separately on the upper surface of the first wall 1. This facilitates the construction operation of the workers and reduces the difficulty of laying. The overlapping area between the first sub-waterproof layer 71 and the second sub-waterproof layer 72 prevents liquid from penetrating into the first shielding component 4, prevents the first shielding component 4 from rusting, and improves the waterproof effect.
[0037] Furthermore, since the first shielding component 4 is made of metal and the first wall 1 is made of concrete, the shrinkage deformation of the metal and the concrete is inconsistent, which will have a pulling effect on the first waterproof layer 7. The polymer sealant layer 6 is set between the upper surface of the first shielding component 4 and the first wall 1. The polymer sealant layer 6 can produce a small deformation, providing a reserved deformation space for the first waterproof layer 7 and playing a role in flexible transition.
[0038] In some alternative embodiments, the protective component further includes a second waterproof layer 8, which extends from the surface of the second shielding component 5 away from the first wall 1 to the surface of the second wall 2 facing the first shielding component 4.
[0039] Specifically, the second waterproof layer 8 extends from the surface of the second shielding member 5 facing away from the first wall 1 to the surface of the second wall 2 facing the second shielding member 5. The second waterproof layer 8 is used to protect the second shielding member 5, prevent rainwater from entering the second shielding member 5, thereby preventing the second shielding member 5 from rusting and improving the service life of the second shielding member 5.
[0040] Furthermore, one end of the second shielding component 5 is disposed inside the second wall 2, and the other end of the second shielding component 5 extends toward the first wall 1, so that the second shielding component 5 has a certain slope so that rainwater can be discharged.
[0041] In some alternative embodiments, the protective structure further includes a flexible sealing layer 9 disposed in the area where the second waterproof layer 8, the surface of the second shielding member 5 facing away from the first wall 1, and the surface of the second wall 2 facing the first shielding member 4 intersect.
[0042] Specifically, the second shielding component 5 is made of metal, while the second wall 2 is made of concrete. The shrinkage deformation of metal and concrete is inconsistent, which will have a pulling effect on the second waterproof layer 8. The flexible sealing layer 9 can produce a small amount of deformation, providing a reserved deformation space for the second waterproof layer 8 and playing a role in flexible transition.
[0043] In some optional embodiments, the first shielding component 4 includes a fixing element 41 and a first shielding element 42. The fixing element 41 is disposed on the upper surface of the first wall 1, and one end of the first shielding element 42 is disposed on the fixing element 41. The first shielding element 42 and the fixing element 41 are disposed at a first preset angle A, and the range of the first preset angle A is 0-180°.
[0044] Specifically, the fixing element 41 is fixed to the first wall 1 by screws 411, which limit the position of the fixing element 41. Optionally, the included angle between the first blocking element 42 and the fixing element 41 is 30°, 45°, 90°, 120°, or 150°. Preferably, the included angle between the first blocking element 42 and the fixing element 41 is 90°. The fixing element 41 is a fixing plate. The first blocking element 42 is a blocking plate. The fixing plate and the blocking plate are integrally formed, or the fixing plate and the blocking plate are welded together.
[0045] Furthermore, the projection of the second shielding component 5 onto the surface of the second wall 2 facing the second shielding component 5 overlaps with the projection of the first shielding element 42 onto the surface of the second wall 2 facing the second shielding component 5. The projection of the second shielding component 5 onto the upper surface of the first wall 1 covers the projection of the first shielding component 4 onto the upper surface of the first wall 1. This results in the formation of a sealing structure by the first shielding component 4, the second shielding component 5, the upper surface of the first wall 1, and the surface of the second wall 2 facing the first shielding component 4. This sealing structure is used to shield the expansion joint k and prevent liquid from entering the expansion joint k. Regardless of how the first wall 1 and the second wall 2 deform, the expansion joint k will always be shielded.
[0046] In some optional embodiments, the first blocking component 4 further includes a second blocking element 43, which is disposed at the end of the first blocking element 42 away from the fixing element 41. The second blocking element 43 and the first blocking element 42 are arranged at a second preset angle B, which is in the range of 0-180°.
[0047] Specifically, the second blocking element 43 is disposed at the end of the first blocking element 42 away from the fixing element 41. The second blocking element 43 extends in a direction away from the second wall 2. The included angle between the second blocking element 43 and the first blocking element 42 is in the range of 0-180°, and can be selected as 30°, 45°, 90°, 120°, or 150°. Preferably, the included angle between the second blocking element 43 and the first blocking element 42 is 90°. The included angle between the first blocking element 42 and the fixing element 41 is in the range of 0-180°, and can be selected as 30°, 45°, 90°, 120°, or 150°. Preferably, the included angle between the first blocking element 42 and the fixing element 41 is 90°.
[0048] In some optional embodiments, the second shielding component 5 includes a first embedded element 51 and a third shielding element 52. The first embedded element 51 is disposed inside the second wall 2, one end of the third shielding element 52 is disposed on the first embedded element 51, and the other end of the third shielding element 52 extends toward the first wall 1.
[0049] Specifically, the first embedded element 51 is disposed inside the second wall 2, and one end of the third shielding element 52 is disposed inside the second wall 2 and connected to the first embedded element 51. Optionally, the third shielding element 52 is arc-shaped, or the third shielding element 52 includes two third sub-shielding plates, one end of which is perpendicular to the fixing component, and the angle between the third sub-shielding plate and the other third sub-shielding plate is 90° to 180°. Preferably, the angle between the two third sub-shielding plates is 175°. After liquid is spilled on the second shielding component 5, it will flow down the third sub-shielding plate to the upper surface of the first wall 1.
[0050] In some optional embodiments, the second shielding component 5 includes a fourth shielding element 54, which is disposed at the end of the third shielding element 52 away from the first embedded element 51. The third shielding element 52 and the fourth shielding element 54 are arranged at a third preset angle C, and the value of the third preset angle C is in the range of 0-180°.
[0051] Specifically, the included angle between the third shielding element 52 and the fourth shielding element 54 ranges from 0 to 180°. Optionally, the included angle between the third shielding element 52 and the fourth shielding element 54 is 30°, 45°, 90°, 120°, or 150°, with a preferred included angle of 90°. The projection of the third shielding element 52 onto the upper surface of the first wall 1 overlaps with the projection of the first shielding component 4 onto the upper surface of the first wall 1. The projection of the fourth shielding element 54 onto the surface of the second wall 2 facing the second shielding component 5 overlaps with the projection of the first shielding element 42 onto the surface of the second wall 2 facing the second shielding component 5. This results in a sealing structure formed by the first shielding component 4, the second shielding component 5, the upper surface of the first wall 1, and the surface of the second wall 2 facing the first shielding component 4. This sealing structure is used to shield the expansion joint k, preventing liquid from entering the expansion joint k. Regardless of how the first wall 1 and the second wall 2 deform, the expansion joint k will always be shielded.
[0052] On the other hand, this application also provides a shielding structure, which is respectively disposed on the first wall 1 and the second wall 2 forming the expansion joint k. The height of the first wall 1 is less than the height of the second wall 2. The shielding structure includes: a first shielding component 4, which is vertically disposed on the upper surface of the first wall 1, and the upper surface of the first wall 1 is connected to the surface of the first wall 1 that forms the expansion joint k; a second shielding component 5, one end of which is disposed on the second wall 2, and the other end of which extends toward the first wall 1. The projection of the second shielding component 5 onto the upper surface of the first wall 1 covers the projection of the first shielding component 4 onto the upper surface of the first wall 1. The projection of the second shielding component 5 onto the surface of the second wall 2 facing the second shielding component 5 overlaps with the projection of the first shielding component 4 onto the surface of the second wall 2 facing the second shielding component 5. The first shielding component 4 is the first shielding component 4 mentioned in any of the above claims. The second shielding component 5 is the second shielding component 5 mentioned in any of the above claims.
[0053] Specifically, the first shielding component 4 and the second shielding component 5 are respectively installed on the first wall 1 and the second wall 2 at different heights. The first wall 1 and the second wall 2 are both made of concrete. The first wall 1 and the second wall 2 are prone to cracking. This is mainly due to stress concentration and temperature changes, which can easily cause cracks between the first wall 1 and the second wall 2 and damage the waterproof layer between the first wall 1 and the second wall 2. Due to the deformation at the junction of the first wall 1 and the second wall 2, there are problems such as sealing failure and opening at the joint, which leads to water leakage at the roof expansion joint k. The shielding structure in this application includes a first shielding component 4 and a second shielding component 5. There is no connection between the first shielding component 4 and the second shielding component 5. The first shielding component 4 is disposed on the upper surface of the first wall 1, and the second shielding component 5 is disposed on the surface of the second wall 2 that forms the expansion joint. The projection of the second shielding component 5 on the upper surface of the first wall 1 covers the projection of the first shielding component 4 on the upper surface of the first wall 1. The projection of the second shielding component 5 on the surface of the second wall 2 facing the second shielding component 5 overlaps with the projection of the first shielding component 4 on the surface of the second wall 2 facing the second shielding component 5. This makes the first shielding component 4, the second shielding component 5, the upper surface of the first wall 1, and the surface of the second wall 2 facing the first shielding component 4 form a sealing structure. This sealing structure is used to shield the expansion joint k and prevent liquid from entering the expansion joint k. No matter how the first wall 1 and the second wall 2 deform, the expansion joint k will always be shielded.
