Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a base plate post-cast strip structure. Background Art

[0002] Post-cast joints are concrete strips placed in foundation slabs, walls, and beams during construction to prevent harmful cracks caused by uneven shrinkage or settlement of reinforced concrete structures. These strips are designed according to design or construction specifications and are temporarily divided into sections. After a period of time, concrete is poured across these construction joints to connect the structure. Post-cast joints should be poured during cooler temperatures. Cement or concrete with a trace amount of aluminum powder added to cement should be used. Its strength should be one level higher than that of the component to prevent cracks between the new and old concrete, creating weak spots. The location of post-cast joints should also take into account the consumption factors of formwork and other measures.

[0003] Typically, the post-cast strip needs to be left in place for a long time after it is formed, and it needs to be chiseled before pouring. After chiseling, a large amount of sediment and water will remain in the post-cast strip, which needs to be manually cleaned before pouring. However, since the post-cast strip also contains steel bars, it is difficult to manually clean the sediment and water in the post-cast strip. The actual cleaning process requires a lot of manpower, is time-consuming, and has poor cleaning effects. Summary of the Invention

[0013] Optionally, the matching piece is further provided with a plurality of communicating holes, and two ends of the communicating holes are respectively communicated with the first slot and the positioning hole.

[0014] By adopting the above technical solution, during the pouring process, after the concrete fills the remaining space of the first slot, it can enter the positioning hole through the connecting hole, so that the concrete fills the positioning hole, thereby improving the overall structural strength of the bottom plate post-cast strip structure.

[0015] Optionally, the fixing frame has a plurality of second slots for engaging the second steel mesh, and the fixing frame is also provided with a plurality of clamping members, the clamping members are hinged to the fixing frame, and elastic members are provided at the hinged position of the clamping members and the fixing frame, and the elastic members drive the clamping members to rotate in the direction close to the second slots until they are against the second steel mesh engaged in the second slots.

[0018] By adopting the above technical solution, the connection and installation of the cover plate and the blocking assembly can be facilitated, the position stability of the cover plate after installation can be improved, and at the same time, the second steel mesh can be quickly and accurately positioned after entering the post-casting zone space.

[0019] Optionally, a fitting groove is provided at the end of the first steel mesh, and a fitting portion adapted to the fitting groove is provided at the end of the second steel mesh. After the fitting portion is inserted into the fitting groove, the displacement of the second steel mesh is restricted except in a direction opposite to the insertion direction.

[0020] By adopting the above technical solution, the second steel mesh can be accurately positioned with the first steel mesh, and at the same time, the second steel mesh can be kept in a position coordinated with the first steel mesh, making it convenient for construction workers to connect and fix the two through the connecting sleeve.

[0021] Optionally, the cover plate further has a second opening at the end of the first sliding groove away from the first opening for the auxiliary protrusion to leave the first sliding groove, and the interior of the cover plate is further provided with a limiting member for preventing the auxiliary protrusion from sliding toward the second opening.

DETAILED DESCRIPTION

[0040] The following is combined with Figure 1-9 This application is described in further detail.

[0041] The embodiment of the present application discloses a base plate post-cast strip structure.

[0042] Reference Figure 1 and Figure 2The base plate post-cast strip structure includes two blocking components 2 built on the foundation 1, a cover plate 3 for preventing debris from entering the post-cast strip space 6, and a second steel mesh 5 for improving the structural strength of the post-cast strip. The post-cast strip space 6 is enclosed between the two blocking components 2 and between the cover plate 3 and the foundation 1. The first steel mesh 4 for improving the structural strength of the base plate is arranged on both sides of the post-cast strip space 6. The first steel mesh 4 is arranged at the same time during the construction of the blocking components 2. After the blocking components 2 are built, the cover plate 3 is installed to cover the post-cast strip space 6. The second steel mesh 5 enters the post-cast strip space 6 at the same time as the cover plate 3 is installed and cooperates with the two first steel meshes 4. After the spaces on both sides of the post-cast strip space 6 are poured, they are left for a period of time, and then the cover plate 3 is opened and the second steel mesh 5 is taken out at the same time. The construction workers chisel the post-cast strip and clean the sediment and accumulated water inside the post-cast strip. After that, the second steel mesh 5 is matched with the first steel mesh 4 again and fixedly connected. Finally, the post-cast strip is poured.

[0043] The blocking assembly 2 includes a positioning member 21, a plurality of blocking members 22, a plurality of water-stopping members 23, and an auxiliary member 24. The positioning member 21 is fixedly connected to the foundation 1 and the two positioning members 21 are parallel to each other. In this embodiment, the positioning members 21 are preferably formed by pouring concrete.

[0044] The blocking piece 22 is located above the positioning piece 21 , and the blocking piece 22 abuts against the positioning piece 21 . The accompanying drawings only show a portion of the post-cast strip structure. In actual applications, a plurality of blocking pieces 22 are usually fixedly connected to the same positioning piece 21 .

[0045] Reference Figure 1 and Figure 3 The blocking member 22 comprises two mating members 221. Each mating member 221 has a plurality of locating holes 2211 spaced evenly along its length. The locating holes 2211 extend through the blocking member 22. Several first locating pins 211 are embedded within the positioning member 21. One end of each first locating pin 211 extends through the top of the positioning member 21, and the length of each first locating pin 211 is perpendicular to the foundation 1. The two mating members 221 are pluggably mounted on the same positioning member 21 through the engagement of the first locating pins 211 with the locating holes 2211. The length of the first locating pin 211 extending from the positioning member 21 is less than half the length of the locating holes 2211. In this embodiment, the mating members 221 are preferably made of steel.

[0046] Reference Figure 3 and Figure 4The blocking member 22 also includes a first slot 2212 for the end of the first reinforcement mesh 4 to be inserted into. The bottom of the first slot 2212 is arc-shaped to accommodate the shape of the reinforcement. The sides of the two mating members 221 on the same positioning member 21 are fitted against each other, and the openings of the first slots 2212 of the two mating members 221 face opposite directions (one up and one down). In this embodiment, the opening of the first slot 2212 on the mating member 221 near the post-casting strip space 6 is preferably facing upward. The first slots 2212 of the two mating members 221 are interconnected, and the interconnected portion forms a perforation for the end of the first reinforcement mesh 4 to pass through the blocking member 22. The peripheral side surfaces of the end of the first reinforcement mesh 4 are simultaneously against the bottoms of the two first slots 2212.

[0047] A water stop 23 is mounted on the side of the blocking member 22 away from the positioning member 21. Another blocking member 22 is also mounted on the side of the water stop 23 away from the blocking member 22. After the second first reinforcement mesh 4 is arranged, its end passes through the other blocking member 22 and enters the post-cast strip space 6. After the water stop 23 is installed, the water stop 23 fits against both blocking members 22. In this embodiment, the water stop 23 is a water-swelling water stop 23.

[0048] Several second locating pins 231 are embedded within the waterstop 23, matching the locating holes 2211. These second locating pins 231 extend outward from the waterstop 23 along a straight line in different directions. The length of the second locating pins 231 extending from the waterstop 23 is also less than half the length of the locating holes 2211. After the waterstop 23 and both sealing members 22 are installed, the second locating pins 231 on the waterstop 23 are inserted into the corresponding locating holes 2211 on the mating members 221 on either side.

[0049] Reference Figure 3 and Figure 4 The mating member 221 is further provided with a plurality of connecting holes 2213 for connecting the first slots 2212 with the positioning holes 2211. The connecting holes 2213 are located between the first slots 2212 and adjacent positioning holes 2211. After the post-cast strip structure is constructed, during the pouring process, concrete can enter the first slots 2212 and then flow through the connecting holes 2213 into the positioning holes 2211 to fill the space, thereby improving the pouring effect and quality.

[0050] The auxiliary member 24 assists the cover plate 3 in closing over the post-casting strip space 6. It is installed above a blocking member 22, located farther from the positioning member 21. Several third positioning pins 241 are embedded within the auxiliary member 24. These pins extend out of one side of the auxiliary member 24 in the same direction, and the length of the pins 241 extending out of the auxiliary member 24 is less than half the length of the positioning holes 2211. In this embodiment, the auxiliary member 24 is preferably also made of steel.

[0051] Reference Figure 5 and Figure 6 The auxiliary part 24 has an auxiliary protrusion 242 on the side away from the direction in which the third positioning pin 241 passes through. The auxiliary protrusion 242 and the auxiliary part 24 are detachably connected. In this embodiment, the auxiliary protrusion 242 and the auxiliary part 24 are preferably fixedly connected by a plurality of screws, and the screws are omitted in the drawings.

[0052] In this embodiment, the auxiliary member 24 preferably has two auxiliary protrusions 242 mounted thereon, each having a T-shaped cross-section. The cover plate 3 is provided with four corresponding first sliding grooves 31, with the auxiliary protrusions 242 fitting into the first sliding grooves 31. One end of the first sliding groove 31 has a first opening 311 for the auxiliary protrusions 242 to enter the first sliding groove 31. The auxiliary protrusions 242 assist in positioning the cover plate 3 when it is closed, and once they are in the corresponding first sliding groove 31, they can position the cover plate 3.

[0053] Reference Figure 2 and Figure 5 A fixing bracket 32 ​​is fixedly mounted on the end face of the first sliding groove 31 where the first opening 311 is located. The fixing bracket 32 ​​is provided with a plurality of second slots 321 for the second reinforcement mesh 5 to be clamped and fixed. The openings of the plurality of second slots 321 are oriented in the opposite direction to the sliding direction of the cover plate 3 during installation. The fixing bracket 32 ​​is also provided with a plurality of clamping members 322 for fixing the second reinforcement mesh 5. The plurality of clamping members 322 are hinged to the fixing bracket 32, and the rotation axis direction of the clamping members 322 is horizontal and perpendicular to the length direction of the first sliding groove 31. The plurality of clamping members 322 correspond one-to-one to the plurality of second slots 321. An elastic member 323 is also installed at the hinged position between the clamping members 322 and the fixing bracket 32. The elastic member 323 drives the clamping members 322 to rotate in a direction closer to the second slots 321. After the clamping members 322 rotate to abut against the fixing bracket 32, the clamping members 322 also abut against the second reinforcement mesh 5. In this embodiment, the elastic member 323 is preferably a torsion spring, and only the position of the torsion spring is shown in the drawings.

[0054] There are two second steel meshes 5 installed and fixed on the fixing frame 32. The two second steel meshes 5 are parallel to each other. After the second steel meshes 5 are installed and fixed on the fixing frame 32, some of the steel bars on the second steel meshes 5 are inserted into the second slots 321, and the steel bars adjacent to and perpendicular to the steel bars inserted into the second slots 321 are offset from the fixing frame 32. The second steel meshes 5 are thus fixed in their installation position on the fixing frame 32.

[0055] Reference Figure 6 and Figure 7The first sliding groove 31 further has a second opening 312 at one end away from the first opening 311, through which the auxiliary protrusion 242 can exit the first sliding groove 31. A stopper 33 is also installed inside the cover plate 3 to prevent the auxiliary protrusion 242 from sliding in the first sliding groove 31 toward the second opening 312. A second sliding groove 34 is also defined inside the cover plate 3 for the stopper 33 to slide. The second sliding groove 34 communicates with the first sliding groove 31, and the stopper 33 slides perpendicularly to the plane of the cover plate 3.

[0056] Reference Figure 6 、 Figure 7 and Figure 8 After the cover plate 3 is installed, the stopper 33 partially enters the first sliding groove 31 under the action of gravity and abuts against the groove wall of the first sliding groove 31. At this time, the stopper 33 limits the sliding of the auxiliary protrusion 242. When the auxiliary protrusion 242 abuts the stopper 33, the end of the second steel mesh 5 is aligned with and abuts the end of the first steel mesh 4 that penetrates the post-casting zone space 6.

[0057] Reference Figure 4 and Figure 8 The surface of the end of the first steel mesh 4 that penetrates the post-cast strip has an external thread 101, and a connecting sleeve 7 for connecting and fixing the end of the first steel mesh 4 with the end of the second steel mesh 5 is installed on the end of the first steel mesh 4 that penetrates the post-cast strip. The connecting sleeve 7 is sleeved on the first steel mesh 4, and the inner side surface of the connecting sleeve 7 has internal threads 102 at both ends in its length direction, and the length dimension of the connecting sleeve 7 is smaller than the length dimension of the portion of the end of the first steel mesh 4 that penetrates the post-cast strip space 6. When the first steel mesh 4 is arranged, the connecting sleeve 7 is threadedly connected to the first steel mesh 4, and the position of the connecting sleeve 7 on the first steel mesh 4 is fixed. The first steel mesh 4 can determine the arrangement position of the first steel mesh 4 relative to the interception assembly with the help of the connecting sleeve 7. At this time, the end of the connecting sleeve 7 close to the first steel mesh 4 is against the end of the interception assembly close to the post-cast strip space 6.

[0058] The end surface of the second reinforcement mesh 5 that abuts against the first reinforcement mesh 4 also has external threads 101. When the end of the connecting sleeve 7 away from the blocking assembly 2 is threadedly connected to the second reinforcement mesh 5, the connecting sleeve 7 is simultaneously mounted on the ends of the first reinforcement mesh 4 and the second reinforcement mesh 5. In this embodiment, the connecting sleeve 7 is shown in the drawings as a hollow cylindrical structure. In actual use, the outer surface of the connecting sleeve 7 also has a structure that facilitates the use of tools by construction workers to rotate it.

[0059] Reference Figure 9The ends of the first steel mesh 4 that penetrate into the post-casting strip space 6 are each provided with a mating groove 41. The opening of the mating groove 41 is horizontal and opposite to the sliding direction of the cover plate 3 during installation. The ends of the second steel mesh 5 that are aligned with and abut against the first steel mesh 4 are each provided with a mating portion 51 that is adapted to the mating groove 41. When the cover plate 3 slides relative to the blocking assembly 2 until the auxiliary protrusion 242 abuts against the limiter 33, the mating portion 51 on the second steel mesh 5 is inserted into the corresponding mating groove 41 on the first steel mesh 4 to form a mating engagement. At this time, the second steel mesh 5 is connected and mated to the first steel mesh 4 on both sides of it, and the displacement of the second steel mesh 5 is restricted except in the direction of the mating groove 41.

[0060] Reference Figure 4 、 Figure 6 and Figure 7 The cover plate 3 is also equipped with a control assembly 8 for controlling the sliding movement of the two limiters 33. The control assembly 8 can simultaneously and synchronously control the sliding movement of the two limiters 33. The other two limiters 33 have chamfers 331 on their ends near the first opening 311 and the first sliding groove 31. When the auxiliary protrusions 242 abut against these limiters 33, the auxiliary protrusions 242 can continue to slide within the first sliding groove 31. The chamfers 331 force the limiters 33 to slide away from the first sliding groove 31, leaving space for the auxiliary protrusions 242 to continue sliding. The limiters 33 controlled by the control assembly 8 are different from the aforementioned limiters 33 in that their sliding movement can only be controlled by the control assembly 8.

[0061] The control assembly 8 includes a drive shaft 81 and two cams 82. The cover plate 3 defines a mounting hole 35 for the drive shaft 81 to penetrate and install. The length of the mounting hole 35 is parallel to the plane of the cover plate 3 and perpendicular to the length of the first sliding slot 31. The mounting hole 35 also communicates with the two second sliding slots 34. One end of the drive shaft 81, inserted into the mounting hole 35, is pivotally connected to the cover plate 3. The axis of rotation of the drive shaft 81 is parallel to the length of the mounting hole 35. The other end of the drive shaft 81 is an operating end 811 located on one side of the cover plate 3, allowing operators to control its rotation. In this embodiment, the shaft maintains its position regardless of its position.

[0062] A clearance hole 332 is defined in the center of the stopper 33, which is controlled by the control assembly 8, for the drive shaft 81 to pass through. A cam 82 is mounted on the end of the drive shaft 81 that extends through the mounting hole 35, with two cams 82 positioned in the clearance holes 332, respectively. As the drive shaft 81 rotates, one end of the cam 82 constantly abuts against the wall of the clearance hole 332 above it. The rotation of the drive shaft 81, via the cam 82, forces the stopper 33 to slide within the second sliding slot 34. When the end with the smallest radius of the cam 82 abuts against the wall of the clearance hole 332, the limiting member 33 abuts against the wall of the first sliding groove 31, thereby limiting the auxiliary protrusion 242; when the end with the largest radius of the cam 82 abuts against the wall of the clearance hole 332, the limiting member 33 abuts against the wall of the second sliding groove 34 away from the wall of the first sliding groove 31, and the auxiliary protrusion 242 can continue to slide in the direction close to the second opening 312; during the process of the auxiliary protrusion 242 continuing to slide in the direction close to the second opening 312, the second steel mesh 5 remains in position unchanged under the cooperation of the matching portion 51 and the matching groove 41, and the cover plate 3 continues to move relative to the blocking assembly 2, and the second steel mesh 5 will apply a force to the clamping member 322 in the direction away from the second clamping groove 321, causing the clamping member 322 to rotate, providing space for the second steel mesh 5 to disengage from the fixing frame 32; when the auxiliary protrusion 242 slides to the position of the second opening 312, the second steel mesh 5 disengages from the fixing frame 32.

[0063] The implementation principle of the post-cast strip structure of the bottom plate in the embodiment of the present application is as follows:

[0064] First, the position of the post-casting strip is determined on the foundation 1 by fixing and connecting the two positioning members 21, then the blocking assembly 2 is built, and the first reinforcement mesh 4 is arranged during the installation and fixing of the fitting member 221. Then, the second reinforcement mesh 5 is fixed on the fixing frame 32, and then the cover plate 3 is used to cover the post-casting strip space 6, so that the second reinforcement mesh 5 is abutted against the first reinforcement mesh 4 on both sides to form a fit;

[0065] Then, the parts on both sides of the post-cast strip space 6 are cast to form the base plate body. After the post-cast strip structure is left for a period of time, the cover plate 3 is opened and the second steel mesh 5 is taken out of the post-cast strip space 6. Then, the post-cast strip is chiseled and the sediment and accumulated water in the post-cast strip space 6 are cleaned. After the chiseling and cleaning are completed, the cover plate 3 and the blocking component 2 are installed again, and the control component 8 is used to make the cover plate 3 taken out after sliding, so that the second steel mesh 5 can maintain the fit with the first steel mesh 4 in the post-cast strip space 6.
