Description

Technical Field

[0001] This application belongs to the technical field of building waterproofing construction, specifically relating to a post-pouring strip construction structure. Background Technology

[0002] A post-cast strip is a concrete strip left at a corresponding location in the foundation slab, wall, or beam during building construction to prevent harmful cracks that may occur in reinforced concrete structures due to uneven shrinkage or settlement. It is installed according to design or construction specifications. The post-cast strip area temporarily divides the structure into several parts. After pouring concrete into the post-cast strip area, the concrete joint is then poured again after the internal shrinkage of the concrete structure to connect the several parts into a whole.

[0003] In the existing technology, there is a lack of protection for the post-pouring strip area, which leads to the presence of foreign objects in the post-pouring strip area and affects the concrete pouring quality of the post-pouring strip area. Utility Model Content

[0004] The purpose of this application is to provide a construction structure for post-cast strips to protect the post-cast strip area.

[0005] To achieve the above objectives, this application provides a post-cast strip construction structure, comprising:

[0006] A channel-shaped component is mounted on the main structure on both sides of the post-pouring strip area and closes the post-pouring strip area. The groove of the channel-shaped component is arranged facing the post-pouring strip area, and a through-hole is formed on the channel-shaped component.

[0007] A covering layer is applied to the outer wall surface of the grooved component and seals the casting hole.

[0008] In some embodiments, the covering layer extends to the outer wall surface of the structural body and seals the gap between the grooved member and the structural body.

[0009] In some embodiments, the covering layer is attached to both the outer wall surface of the grooved component and the outer wall surface of the main structure.

[0010] In some embodiments, the grooved member includes:

[0011] Supporting parts are provided on the main structural components on both sides of the post-cast strip area;

[0012] The cover plate is mounted on the support, the casting hole is formed on the cover plate, and the covering layer covers the outer wall surface of the cover plate and the outer wall surface of the support.

[0013] In some embodiments, the support portions are respectively arranged on the main structure on both sides of the post-cast strip area, the support portions on both sides of the post-cast strip area are symmetrically arranged, and the center of the casting hole is located in the plane of symmetry of the support portions on both sides.

[0014] In some embodiments, the support portion and the cover portion are perpendicular to each other.

[0015] In some embodiments, the outer wall surface of the support portion is flush with the end of the cover plate portion.

[0016] In some embodiments, the inner wall surface of the support is flush with the end of the main structure.

[0017] In some embodiments, the cover layer includes an additional layer that is fitted to the outer wall surface of the groove member.

[0018] In some embodiments, the covering layer further includes a waterproof layer that covers the outer wall surface of the additional layer.

[0019] In some embodiments, the distance between the end of the additional layer and the outer wall of the grooved member is less than the distance between the end of the waterproof layer and the outer wall of the grooved member.

[0020] The post-cast strip construction structure provided by this application has the following beneficial effects through the above technical solution:

[0021] After the main structure is poured and the post-pouring strip area is set, a waiting period is generally required before the concrete pouring of the post-pouring strip area can proceed. Due to the complex environmental conditions at the construction site, debris and foreign objects may enter the post-pouring strip area during this period. Therefore, the post-pouring strip area needs to be cleaned before pouring to prevent debris and foreign objects from adversely affecting the quality of the concrete pouring. In this application, the post-pouring strip area is sealed by setting groove-shaped components with pouring holes on the main structure on both sides of the post-pouring strip area, thereby reducing the entry of debris and foreign objects into the post-pouring strip area. At the same time, a covering layer is used to seal the pouring holes, thereby preventing debris and foreign objects from entering the post-pouring strip area through the pouring holes, thus achieving protection of the post-pouring strip area and the reserved structures within the post-pouring strip area during the waiting period.

[0022] Other features and advantages of the embodiments of this application will be described in detail in the following detailed description section. Attached Figure Description

[0028] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0029] The following description, with reference to the accompanying drawings, outlines the terminology of the post-cast strip construction structure according to this application.

[0030] Post-cast strip: A post-cast strip is a concrete strip left at corresponding locations in the foundation slab, walls, and beams during building construction to prevent harmful cracks that may occur in reinforced concrete structures due to uneven shrinkage or settlement, as required by design or construction specifications. The post-cast strip area 200 temporarily divides the structure into several parts. After pouring concrete into the post-cast strip area 200, the concrete joint concrete is poured again after the internal shrinkage of the concrete structure to connect the several parts into a whole.

[0031] like Figure 1 and Figure 2 As shown, a specific embodiment of this application provides a post-pouring strip construction structure 100, including a groove-shaped component 2 and a covering layer. The groove-shaped component 2 is mounted on the main structure 1 on both sides of the post-pouring strip area 200 and closes the post-pouring strip area 200. The groove opening of the groove-shaped component 2 is arranged facing the post-pouring strip area 200, and a through-hole 10 is formed on the groove-shaped component 2. The covering layer is covered and disposed on the outer wall surface of the groove-shaped component 2 and closes the pouring hole 10.

[0032] The post-cast strip area 200 divides the main structural element 1 into several parts to avoid uneven shrinkage or settlement caused by the excessive size of a single main structural element 1. The post-cast strip concrete reconnects the divided main structural elements 1 into a whole. In other words, the post-cast strip concrete also belongs to the main structural element 1 after construction. Therefore, the quality of the post-cast strip concrete also affects the quality of the main structural element 1, and debris and foreign objects entering the post-cast strip area 200 will affect the quality of the post-cast strip concrete. In this application, the post-cast strip area 200 is closed by installing trough-shaped members 2 on both sides of the main structural element 1, thereby preventing debris and foreign objects from entering the post-cast strip area 200 and thus protecting the post-cast strip area 200.

[0033] Furthermore, a reserved steel bar 8 needs to be installed in the post-pouring strip area 200 to strengthen the connection with the main structure 1; a waterproof membrane is laid on the main structure 1, and a membrane overlap is set in the post-pouring strip area 200 to facilitate the overlap of the waterproof membrane on the post-pouring strip concrete and the waterproof membrane on the main structure 1; a reserved water-stop steel plate 9 is installed at the end of the main structure 1 to enhance the waterproof effect at the joint between the post-pouring strip concrete and the main structure 1. In other words, there are various reserved components in the post-pouring strip area 200. Due to the complex construction site environment, the reserved components are contaminated or even damaged before the post-pouring strip concrete is poured. Therefore, it will affect the connection strength and waterproof integrity between the post-pouring strip concrete and the main structure 1. It can be seen that in this application, setting the grooved component 2 to protect the post-pouring strip area 200 can also improve the structural strength and waterproof quality of the building structure.

[0034] Specifically, when pouring concrete for the post-pouring strip, the concrete can be poured into the post-pouring strip area 200 from the pouring hole 10 after removing the covering layer within the pouring hole 10, without damaging the trough member 2, thereby improving the feasibility of the post-pouring strip construction structure 100.

[0035] Furthermore, the channel-shaped component 2 is mounted on the main structural body 1 on both sides of the post-pouring strip area 200. The area enclosed by the channel-shaped component 2 and the main structural body 1 is larger than the post-pouring strip area 200, so as to ensure that the outer wall surface of the post-pouring strip concrete is at least flush with the outer wall surface of the main structural body 1, thereby ensuring that the overall thickness of the building structure meets the design standards and thus improving the structural strength of the building structure.

[0036] It should be noted that the groove 2 refers to a semi-enclosed component with a groove. The shape of the groove of the groove 2 can be a square groove, a U-shaped groove, etc. The groove opening of the groove 2 refers to the groove opening of the groove of the groove 2, that is, the open end of the groove 2.

[0037] In some embodiments, the covering layer extends to the outer wall surface of the main structure 1 and seals the gap between the groove 2 and the main structure 1, thereby improving the sealing performance of the post-pouring strip construction structure 100 and thus improving the waterproofing effect of the post-pouring strip area 200 after construction.

[0038] Specifically, the covering layer includes a protective layer 5, a waterproof layer 4, and an additional layer 3, which are stacked together. The additional layer 3 is adhered to the outer wall surface of the channel member 2 and the outer wall surface of the main structure 1. In other words, the roll material splicing originally set in the post-pouring strip area 200 is eliminated, and the waterproof layer 4 is directly constructed on the outer wall surface of the main structure 1 and the channel member 2. Therefore, the waterproof construction of the main structure 1 and the post-pouring strip concrete can be completed without removing the channel member 2, which improves the feasibility of the post-pouring strip construction structure 100. At the same time, the additional layer 3 is set to increase the waterproof effect at the pouring hole 10 and the joint between the channel member 2 and the main structure 1.

[0039] Furthermore, the rolled material may become contaminated during the concrete pouring process in the post-pouring strip area 200, thus affecting the waterproofing effect of the post-pouring strip area 200. The waterproofing effect of the post-pouring strip area 200 after construction can be improved by directly applying the waterproofing layer 4 to the outer wall surface of the main structure 1 and the trough-shaped component 2.

[0040] In fact, when pouring concrete for the post-pouring strip, it is necessary to remove the protective layer 5, waterproof layer 4 and additional layer 3 near the pouring hole 10. After the pouring is completed, the protective layer 5, waterproof layer 4 and additional layer 3 near the pouring hole 10 need to be repaired. Since the repair area is limited to the vicinity of the pouring hole 10, the construction process is simple and quick. It can be seen that while greatly improving the waterproof effect of the post-pouring strip area 200 after construction, the construction process is also very convenient.

[0041] Preferably, the end of the additional layer 3 is closer to the outer wall surface of the channel member 2 than the end of the waterproof layer 4. The additional layer 3 is mainly used for waterproofing the post-pouring strip area 200, and the waterproof layer 4 is mainly used for waterproofing the main structure 1. Therefore, it is only necessary to ensure that the additional layer 3 can seal the gap between the channel member 2 and the main structure 1, without extending the additional layer 3 too far into the main structure 1, thereby reducing the cost of the post-pouring strip construction structure 100 while ensuring the waterproofing effect.

[0042] It should be noted that both the additional layer 3 and the waterproof layer 4 can be made of various types of waterproof membranes.

[0043] Those skilled in the art will understand that, in addition to the aforementioned covering layer including protective layer 5, waterproof layer 4 and additional layer 3, for cases where the waiting time for pouring in the post-pouring strip area 200 is not long, only additional layer 3 can be set as a covering layer to seal the joint between the pouring hole 10, the groove 2 and the main structure 1, thereby reducing the construction arrangement of removing the waterproof layer 4 and protective layer 5 at the pouring hole 10, and thus reducing the difficulty and cost of construction operations.

[0044] Furthermore, while only setting the additional layer 3 as a covering layer, the waterproof membrane on the main structure 1 can be constructed and the interface can be reserved to the joint between the channel member 2 and the main structure 1, but the waterproof membrane is not extended to cover the entire outer wall of the channel member 2. This also reduces the construction arrangement of removing the waterproof layer 4 and the protective layer 5 at the pouring hole 10. In addition, the construction of laying the waterproof membrane on the main structure 1 and the construction of the post-pouring strip structure 100 can be carried out simultaneously, thereby speeding up the construction progress of the building structure.

[0045] In some embodiments, the groove-shaped component 2 includes a support portion 21 and a cover portion 22, wherein the support portion 21 is disposed on the main body 1 on both sides of the post-pouring strip area 200; the cover portion 22 is mounted on the support portion 21, the pouring hole 10 is formed on the cover portion 22, and the covering layer is disposed on the outer wall surface of the cover portion 22 and the outer wall surface of the support portion 21.

[0046] Specifically, the support component 21 is a cast-in-place concrete member. The construction process of the support component 21 is as follows: First, reinforcing bars are installed on the main body of the structure; then, the casting formwork is erected and fixed; next, concrete is poured; finally, the formwork is removed after curing. Using a cast-in-place concrete member as the support component 21 can effectively strengthen the connection between the support component 21 and the main structure 1, and give the support component 21 itself greater structural strength to support the cover plate 22, thereby improving the reliability of the post-cast strip construction structure 100.

[0047] Furthermore, the cover plate 22 is a prefabricated component. The cover plate 22 is prefabricated according to the size of the post-cast strip area 200. After the support part 21 is poured, the cover plate 22 is simply placed on top of the support part 21 to seal the post-cast strip area 200, thereby improving the construction convenience of the post-cast strip construction structure 100. The cover plate 22 is parallel to the main structure 1, and the covering layer completely covers the outer wall surface of the cover plate 22. Because the outer wall surface of the cover plate 22 is flat, it facilitates the construction of the covering layer and gives it better quality, thereby improving the construction convenience and sealing performance of the post-cast strip construction structure 100.

[0048] Preferably, the support part 21 is divided into two sections and the two support parts 21 are symmetrically arranged in the left-right direction. The support part 21 extends in the front-back direction. The support part 21 on the left side is arranged on the main body 1 on the left side. The support part 21 on the right side is arranged on both sides of the main body 1 in the post-pouring strip area 200. The center of the pouring hole 10 is located in the symmetrical plane of the two support parts 21.

[0049] Furthermore, there are multiple pouring holes 10, which are arranged at intervals along the front-to-back direction, and the center of all pouring holes 10 is located in the plane of symmetry of the two side support parts 21. Since the post-pouring strip area 100 extends along the front-to-back direction, when pouring at different locations, the pouring holes 10 close to the pouring area can be selected for pouring, thereby improving the construction convenience of the post-pouring strip pouring structure.

[0050] Preferably, the support portion 21 and the cover plate portion 22 are perpendicular to each other, the outer wall surface of the support portion 21 is flush with the end of the cover plate portion 22, and the outer wall surfaces of the support portion 21, the cover plate portion 22 and the main body 1 are all horizontal and vertical construction surfaces, which facilitates the construction of the cover layer and improves the construction quality of the cover layer. The construction quality of the cover layer determines the waterproofing quality of the post-pouring strip area 200. Therefore, a better construction quality of the cover layer will improve the waterproofing quality.

[0051] Furthermore, since the concrete contains large stones and these large stones cannot accumulate at small angles, only mortar accumulates at the small angles, resulting in insufficient strength. By setting the inner wall of the support 21 flush with the end of the main structure 1, the small angle between the support 21 and the main structure 1 is avoided, thereby ensuring the strength of the post-cast concrete.

[0052] Preferably, the support portion 21 has an installation groove, and the cover portion 22 has an installation protrusion. The installation protrusion engages with the installation groove to improve the connection stability between the cover portion 22 and the support portion 21.

[0053] Preferably, a sealing material is provided between the cover plate portion 22 and the support portion 21 to improve the connection strength between the cover plate portion 22 and the support portion 21 and increase the sealing performance of the post-pouring strip area 200.

[0054] Those skilled in the art will understand that the trough-shaped component 2 can be made of cast-in-place concrete or precast components, and both are within the scope of protection of this application.

[0055] In some embodiments, the post-cast strip construction structure 100 further includes a support plate 6 and a support member 7. The support plate 6 is disposed on the inner wall surface of the main structural body 1 on both sides of the post-cast strip area 200, and the support member 7 is used to fit the support plate 6 to the main structural body 1. The post-cast strip area 200 is closed by the groove-shaped member 2 and the support plate 6 to carry out the concrete pouring construction of the post-cast strip area 200.

[0056] It should be noted that the structure and function of the pallet 6 and the support 7 are well known to those skilled in the art and are not part of the core inventive points of this application, so they will not be described in detail here.

[0058] In an exemplary embodiment of this application, a left support portion 21 is provided on the left structural body 1 of the post-cast strip area 200, and a right support portion 21 is provided on the right structural body 1 of the post-cast strip area 200. A cover plate portion 22 is mounted on the upper end of the left support portion 21 and the right support portion 21. A support plate 6 is arranged below the post-cast strip area 200, and a support member 7 is arranged below the support plate 6 and presses the support plate 6 against the bottom surface of the structural body 1.

[0059] The right side of the left support part 21 is flush with the right side of the left structural body 1, the left side of the right support part 21 is flush with the left side of the right structural body 1, the left side of the left support part 21 is flush with the left end face of the cover plate part 22, and the right side of the right support part 21 is flush with the right end face of the cover plate part 22.

[0060] The additional layer 3 completely covers the top of the cover plate 22, the left side of the left support 21, and the right side of the right support 21. The left end of the additional layer 3 extends to the top of the left structural body 1, and the additional layer 3 extends to the top of the right structural body 1. The waterproof layer 4 completely covers the top of the cover plate 22, the left side of the left support 21, the right side of the right support 21, and the top of the structural body 1.

[0061] In the exemplary embodiment of this application, the specific construction steps for constructing structure 100 using post-cast strips are as follows:

[0062] First, reinforcing bars are installed on the left main structural body 1 and the right main structural body 1, and the support part 21 is poured;
