Description

Technical Field

[0001] This utility model relates to the technical field of post-pouring strip sealing, and in particular to a construction component for pre-sealing post-pouring strips. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] The elevation difference of the main building structure can cause uneven settlement of the foundation, leading to cracks in the building structure. To avoid cracks, the building structure is often divided into several parts to ensure that the settlement of each part is more uniform. The interval between the top slabs of each part of the building structure is called the post-pouring strip.

[0004] Currently, post-cast strips in building main structure designs are typically poured and sealed 1-2 months after the main structure is topped out. This prolonged presence of post-cast strips causes significant disruptions to subsequent construction, backfilling, and material transfer within the site, ultimately reducing construction efficiency. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a pre-sealing construction component for post-pouring strips.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a construction component for pre-sealing of post-pouring strips, which is set on the post-pouring strips of the main building structure, including a template and a sealing mechanism that are stacked sequentially on the concrete surfaces on both sides of the post-pouring strip. The template is composed of multiple steel plates spliced ​​together, and each steel plate has a pouring pipe opening at its center. The sealing mechanism includes a pad located on the upper side of the template and correspondingly passing through each pouring pipe opening, and a sealing guard plate rotatably set on the pad. After the sealing guard plate is flipped and overlaps with the pad, it is used to seal the top of the pouring pipe opening. The splicing unit is set between two adjacent steel plates and is used to adjust the length of the template according to the applicability of the length of the post-pouring strip.

[0007] Furthermore, the splicing unit includes an insert located on the upper end of one of the steel plates and a slot that is adapted to be horizontally inserted into and located on another adjacent steel plate.

[0008] Furthermore, the insert is evenly provided with a plurality of limiting grooves, which extend out of the slot accordingly. A reinforcing support frame is provided on the surface of the pad near the template, and a corresponding limiting block is provided on the reinforcing support frame to be inserted into the limiting groove.

[0009] Furthermore, the reinforcing support frame consists of three equidistant and parallel support columns, with multiple horizontal plates evenly arranged between the three parallel support columns and connected to the surface of the pad.

[0010] Furthermore, the limiting block has a wedge-shaped external shape, and the limiting block is fitted with an interference fit within the limiting groove.

[0011] Furthermore, the template uses screws and adhesives to help fix the waterstop at the post-pouring strip.

[0012] The beneficial effects of this utility model are reflected in: This invention enables the early closure of the post-pouring strip. Furthermore, the superposition of the formwork and the closure mechanism enhances the support strength of the early closure components, creating favorable conditions for subsequent construction, earthwork backfilling, and material transfer and transportation within the site, thus significantly increasing construction efficiency. Moreover, through the set splicing units, the appropriate number of steel plates can be selected for on-site assembly according to the actual length of the post-pouring strip, making construction convenient.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0016] Please see Figure 1-5 This utility model discloses a construction component for pre-sealing of post-pouring strips, which is installed on the post-pouring strips of the main building structure. It includes a template 1 and a sealing mechanism 2, which are stacked sequentially on the concrete surfaces on both sides of the post-pouring strip. The template 1 is composed of multiple steel plates spliced ​​together, and each steel plate has a pouring pipe opening 3 at its center. The sealing mechanism 2 includes a pad 21 located on the upper side of the template 1 and correspondingly passing through each pouring pipe opening 3, and a sealing guard 22 rotatably disposed on the pad 21. After the sealing guard 22 is flipped to overlap with the pad 21, it is used to seal the top of the pouring pipe opening 3. The splicing unit is set between two adjacent steel plates and is used to adjust the length of the template 1 according to the applicability of the length of the post-pouring strip.

[0017] In practice, the concrete surfaces on both sides of the post-pouring strip are first roughened and the installation location is cleaned. Then, according to the length of the post-pouring strip, an appropriate number of steel plates are selected. With the splicing unit connected, the assembled template 1 is used to cover the post-pouring strip. Subsequently, the combined closing mechanism 2 is superimposed on the template 1, which can realize the early closure of the post-pouring strip. The superposition of the template 1 and the closing mechanism 2 also strengthens the support strength of the early closure component, creating favorable conditions for subsequent construction, earthwork backfilling, and material transfer and transportation within the site, which can greatly increase construction efficiency. After the main structure has settled and stabilized (determined by settlement observation data, usually ≤1mm / month for two consecutive months), the closed protective plate 22, which is installed on the pad plate 21 by hinges, is flipped outwards to expose the pouring pipe 3 welded in the center of the template 1. This facilitates the subsequent pouring of concrete material of a higher grade than the concrete on both sides of the pouring strip through the pouring pipe 3. A suitable expansion agent will be added to compensate for shrinkage. Finally, after the pouring is completed and the test block strength reaches 100% of the design strength, the sealing mechanism 2 and the template 1 can be removed in sequence.

[0018] It should be noted that the pouring should be carried out in layers with a thickness of ≤500mm, and an immersion vibrator should be used to fully vibrate the surface to avoid under-vibration or over-vibration. The pouring direction should be from one end to the other to reduce the risk of cold joints.

[0019] In one embodiment, the splicing unit includes an insert 4 located on the upper side of one of the steel plates and a slot 5 that is horizontally inserted into the insert 4 and located on the adjacent steel plate. This design, with the insert 4 welded to one steel plate and the slot 5 welded to the opposite side of the adjacent steel plate, allows the two steel plates to be horizontally spliced ​​together on the top surface of the post-cast strip to form a complete template 1. Furthermore, the appropriate number of steel plates can be selected according to the actual length of the post-cast strip, making construction convenient and universally applicable.

[0020] In one embodiment, the insert 4 is provided with a plurality of limiting grooves 6 evenly distributed, and the plurality of limiting grooves 6 extend out of the slot 5 accordingly. A reinforcing support frame 23 is provided on the surface of the pad 21 near the template 1, and a limiting block 24 is provided on the reinforcing support frame 23 to be inserted into the limiting groove 6 accordingly. With this design, the plurality of limiting grooves 6 uniformly machined on the insert 4 and the corresponding grooves opened on the slot 5 are connected to the limiting grooves 6. The limiting block 24, which is welded or integrally formed on the surface of the pad 21 and grooved at the end of the reinforcing support frame 23, will cause the two horizontally spliced ​​steel plates to be subjected to a vertical force perpendicular to the insertion direction when the limiting block 24 is inserted into the limiting groove 6.

[0021] In one embodiment, the reinforcing support frame 23 consists of three equidistant and parallel support columns 231, with multiple horizontal plates 232 evenly arranged between the three parallel support columns 231 and connected to the surface of the pad 21. This design, using three parallel support columns 231 and multiple evenly distributed horizontal plates 232 welded or integrally formed between the three support columns 231, ensures that the surface of the pad 21 is evenly stressed, increasing the support strength of the pad 21. This provides a good support surface during the early closure of the post-pouring strip, creating favorable conditions for subsequent construction, earthwork backfilling, and material transfer and transportation within the site, significantly increasing construction efficiency and ensuring construction safety.

[0022] In one embodiment, the limiting block 24 has a wedge-shaped external shape, and the limiting block 24 is interference-fitted within the limiting groove 6. This design, through the use of the wedge-shaped limiting block 24 and the interference fit within the limiting groove 6, ensures that the two horizontally joined steel plates are subjected to a vertical force perpendicular to the insertion direction, preventing separation of the two steel plates and further enhancing the overall stability of the template 1.

[0023] In one embodiment, the template 1 uses screws and adhesive to assist in fixing the waterstop at the post-pouring strip. This design, using screws and adhesive to assist in fixing the waterstop to the template 1 at the post-pouring strip, effectively seals the joint on the template 1 at the post-pouring strip, preventing leakage of grout during subsequent concrete pouring.

[0024] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0025] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0026] Additionally, "multiple" refers to two or more.

[0027] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
