Description

Technical Field

[0001] This invention relates to the structure and construction method of post-cast strips in basements, belonging to the field of building construction technology. Background Technology

[0002] A post-pouring strip is a secondary construction area left at the corresponding position of the foundation slab, wall, or beam in the construction process to prevent harmful cracks that may occur in the cast-in-place reinforced concrete structure due to uneven shrinkage or settlement, in accordance with design or construction specifications.

[0003] Conventional post-pouring strips are separated by post-pouring strip baffles. After the concrete outside the post-pouring strip is poured, the baffles are removed and the post-pouring strip is poured again. At this time, the concrete in the two areas may not be firmly bonded. Therefore, some steel bars are reserved to extend into the post-pouring strip to improve the connection strength between the two areas. However, there may still be some areas where the bond is not firm, so there are certain problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a post-cast strip structure and construction method for basements, which solves the problem of low bonding between the concrete poured in the post-cast strip and the two areas outside the post-cast strip in the prior art.

[0005] The technical problem to be solved by this invention is achieved by the following technical solution: a basement post-cast strip structure, including...

[0006] There are two vertical support plates arranged side by side, extending horizontally. Each vertical support plate has several threaded holes arranged side-by-side in the direction of its extension. Spacer channels are provided between adjacent threaded holes.

[0007] A horizontal support plate is positioned on the side of the vertical support plate where a threaded hole is formed. A connecting threaded post is provided on the horizontal support plate, extending through the threaded hole to securely connect the horizontal and vertical support plates.

[0008] The lower mating block is fixed to one side of the vertical support plate that is far from the horizontal support plate.

[0009] The upper mating block is fixed on the horizontal support plate and is vertically aligned with the lower mating block. The extension direction of the upper and lower mating blocks is the same as that of the vertical support plate, and the opposite surfaces of the upper and lower mating blocks are respectively provided with an upper mating groove and a lower insertion groove.

[0010] The post-cast strip baffle extends in the same direction as the vertical support plate, with one end inserted into the lower insertion groove and engaging with it. The other end of the post-cast strip baffle extends towards the upper mating groove. There is a deformation gap between the post-cast strip baffle and the vertical support plate.

[0011] Drainage channels are provided on the post-cast strip baffle. Several drainage channels are provided, extending vertically along the post-cast strip baffle.

[0012] The outward-turning plate is fixed at one end to the opening of the drainage channel, and the other end of the outward-turning plate extends inclinedly from the post-pouring strip baffle toward the vertical support plate into the deformation interval and abuts against the vertical support plate.

[0013] By adopting the above technical solution, when constructing the post-pouring strip structure, the location of the post-pouring strip is first determined according to the construction situation. Then, a vertical support plate is vertically fixed at the edge of the post-pouring strip, ensuring that the vertical support plate is perpendicular to the pouring plane. Next, a horizontal support plate is placed on the two vertical support plates, ensuring that the horizontal support plate abuts against the vertical support plate. Finally, a connecting threaded post is screwed into the mating threaded hole to fix the horizontal and vertical support plates together. Then, one end of the post-pouring strip baffle is inserted into the lower insertion groove through the extension end of the vertical support plate to complete the insertion. Slide the post-cast strip baffle within the lower insertion groove until its edge is flush with the vertical support plate. Install several baffles along the extension direction of the post-cast strip, ensuring the extension ends of adjacent vertical support plates abut against each other. Pour concrete mortar in the direction away from the two vertical support plates. The concrete mortar is blocked by the post-cast strip baffle, creating pressure on it towards the vertical support plate. Under this pressure, the baffle tilts towards the vertical support plate, and the outward-facing plate is gradually pressed into the drainage channel. The end of the post-cast strip baffle inserted into the lower insertion groove bends, and the end of the post-cast strip baffle facing the upper mating block abuts against the surface of the vertical support plate. After the end of the post-cast strip baffle abuts against the vertical support plate, the post-cast strip baffle no longer tilts and forms a triangular support structure with the vertical support plate. At this point, the end of the concrete mortar facing the vertical support plate forms a slope under the tilting action of the post-cast strip baffle. After removing the post-cast strip structure, when pouring concrete mortar into the post-cast strip, compared to traditional construction, because the height of the poured concrete is fixed, the slope is relatively... The larger vertical surface area increases the contact area between the post-cast strip concrete and the already poured concrete, thus increasing the bonding surface between the two parts of concrete and improving the bonding strength. At the same time, due to the inclined surface structure of the edge of the already poured concrete, after the post-cast strip concrete is poured, the edge of the post-cast strip concrete abuts against the edge of the already poured concrete. At this time, the edge of the already poured concrete can restrict the post-cast strip concrete, ensuring the stability of the post-cast strip concrete and improving the bonding stability between the two.

[0014] The present invention is further configured such that: a plurality of external protrusions are fixedly distributed on the side of the post-pouring strip baffle away from the vertical support plate; a plurality of bent plates extending into the upper mating groove are fixed on the end of the post-pouring strip baffle facing the upper mating groove; the plurality of bent plates are arranged side by side at equal intervals facing the extension direction of the vertical support plate; and a bending groove is opened on the side of the bent plate facing the vertical support plate.

[0015] By adopting the above technical solution, several external protrusions are set on the post-pouring strip baffle, which can improve the surface roughness of the post-pouring strip baffle. This makes it easier for the post-pouring strip baffle to detach from the concrete after it has solidified. Furthermore, a bending plate is selected at an appropriate position according to the actual situation. The bending plate is bent along the bending groove towards the vertical support plate. At this time, steel bars can be inserted from the bending point. The steel bars extend from the already poured concrete toward the post-pouring strip and pass through the bending point of the bending plate and the interval channel to the space between the two vertical support plates. At this time, when pouring the concrete structure in the post-pouring strip, the steel bars can be directly poured into the post-pouring strip, which is conducive to further improving the bonding strength between the post-pouring strip concrete and the already poured concrete. Moreover, the operation of bending the bending plate is simple and greatly reduces the difficulty of operation for workers.

[0016] The invention is further configured such that: an inspection port is provided through the horizontal support plate along the vertical direction, and an inspection cover plate is detachably and fixedly provided on the inspection port.

[0017] By adopting the above technical solution, the opening of the inspection port allows workers to conduct regular inspections and surveys of the post-pouring strip after the horizontal support plate is installed, without having to dismantle the post-pouring strip structure, thus improving the convenience of inspection for workers.

[0018] The invention is further configured such that: two opposite end faces of the inspection port extending in the same direction as the vertical support plate are provided with sliding grooves extending in the same direction as the vertical support plate; a sliding block is slidably disposed in the sliding groove; a connecting rod is fixedly connected between the two sliding blocks; one end of the sliding block extends into the inspection port; a placement block is fixedly disposed at the end of the sliding block extending into the inspection port; the placement block is L-shaped; the vertical end of the L-shaped placement block extends vertically between the two vertical support plates towards the side away from the horizontal support plate; the horizontal end of the L-shaped placement block extends in the same direction as the sliding groove; and an arc-shaped groove is provided on the side of the horizontal end of the placement block facing the horizontal support plate.

[0019] By adopting the above technical solution, reinforcing bars can be placed in the fixed groove. The two ends of the reinforcing bars are respectively matched with the arc-shaped grooves on the two side placement blocks. At this time, the arc-shaped grooves can slightly restrict the movement of the reinforcing bars. By pushing the connecting rod to slide along the extension direction of the sliding groove, the sliding blocks on both sides can be moved at the same time, thereby causing the sliding blocks to move the placement blocks, thus achieving the purpose of making the reinforcing bars move smoothly along the extension direction of the vertical support plate. When the reinforcing bars move to the reserved reinforcing bars that pass through the interval channel, the connecting rod is stopped. Then, the worker can pick up the reinforcing bars placed on the placement blocks through the inspection port and tie them to the reserved reinforcing bar ends to achieve the purpose of extending the length of the reinforcing bars. Moreover, there is no need to disassemble the horizontal support plate, which greatly reduces the difficulty of extending the length of the reinforcing bars and helps to improve construction efficiency.

[0020] The invention is further configured such that: a flipping block is hinged to the side of the horizontal end of the placement block away from the vertical end, and an abutment block is fixedly installed on the flipping block; the abutment block moves toward the vertical end of the placement block or away from the vertical end of the placement block during the flipping block flipping along the hinge.

[0021] By adopting the above technical solution, the flipping block is flipped along the hinge. When a steel bar is placed in the arc groove of the placement block, the abutting block can abut against the steel bar after flipping towards the placement block. At this time, the abutting block can further restrict the movement of the steel bar, which greatly improves the stability of the steel bar during movement.

[0022] The invention is further configured such that: when the abutting block is in the extreme position of moving toward the vertical end of the placement block and is away from the horizontal end of the placement block, an adjusting end head is fixedly installed on one side. The adjusting end head is located at the end of the abutting block away from the flipping block. The two ends of the adjusting end head extend toward the two vertical support plates respectively. A connecting ring is detachably sleeved on the adjusting end head.

[0023] By adopting the above technical solution, and by fitting a connecting ring onto the adjusting end, during the above process, when the reinforcing bar placed on the placement block moves to the reserved reinforcing bar, the connecting ring can be removed from the adjusting end, and one end of the connecting ring can be fitted onto the reserved reinforcing bar, while the other end of the connecting ring is fitted onto the reinforcing bar located in the arc groove of the placement block. At this time, the two reinforcing bars are temporarily connected by the connecting ring. At this time, the worker does not need to hold the reinforcing bar to keep it stable, and the worker can tie the two reinforcing bars with both hands, which greatly improves the convenience of the worker's operation.

[0024] The invention is further configured such that an elastic strip is fixedly installed on one side of the placement block facing the sliding groove, and the elastic strip extends toward the direction of the vertical support plate.

[0025] By adopting the above technical solution, the location where the length of the reinforcing bar needs to be extended during construction often needs to be adjusted according to the actual construction situation. Therefore, when extending the reinforcing bar in the above process, the worker needs to first find the location of the reserved reinforcing bar. However, the reserved reinforcing bar is blocked by the horizontal support plate, making it difficult for the worker to quickly find the location of the reserved reinforcing bar. During the sliding process of the sliding block, the elastic strip can collide with the reserved reinforcing bar. At this time, the worker will generate resistance when pushing the connecting rod, which will make the worker clearly know the location of the reserved reinforcing bar, thus enabling the worker to quickly find the reserved reinforcing bar and greatly improve the worker's construction efficiency. Furthermore, by the elastic strip abutting against the reserved reinforcing bar, the reserved reinforcing bar and the reinforcing bar placed on the placement block can be placed in approximately the same vertical plane. At this time, the worker can complete the operation of putting the two ends of the connecting ring onto the two reinforcing bars more quickly and conveniently, further improving the worker's efficiency in extending the reinforcing bar.

[0026] Construction methods for basement post-cast strip structures, including:

[0027] S1: Place the vertical support plates on opposite sides of the post-cast strip, and place the horizontal support plate on top of the vertical support plates.

[0028] S2: Use connecting threaded posts to fix the horizontal support plate and the vertical support plate together, and insert the post-pouring strip baffle into the downward insertion groove, with the outer flap abutting against the surface of the vertical support plate;

[0029] S3: Pour concrete mortar onto the side of the vertical support plate where the post-pouring strip baffle is installed, and the post-pouring strip baffle blocks the concrete mortar.

[0030] S4: After the concrete mortar has hardened, remove the connecting threaded column and separate the horizontal support plate from the vertical support plate.

[0031] S5: Move the vertical support plate toward the side away from the concrete, and the vertical support plate will cause the post-pouring strip baffle to separate from the concrete.

[0032] The beneficial effects of this invention are:

[0033] 1. Compared to traditional construction, since the height of the poured concrete is fixed, the inclined surface has a larger area than the vertical surface. Therefore, it can increase the contact area between the post-pouring strip concrete and the already poured concrete, increasing the bonding surface between the two parts of concrete. This is beneficial to improving the bonding strength between the two parts of concrete. At the same time, due to the inclined surface structure of the edge of the already poured concrete, after the post-pouring strip concrete is poured, the edge of the post-pouring strip concrete abuts against the edge of the already poured concrete. At this time, the edge of the already poured concrete can restrain the post-pouring strip concrete, ensuring the stability of the post-pouring strip concrete and improving the bonding stability between the two.

[0034] 2. Setting several external protrusions on the post-cast strip baffle can improve the surface roughness of the baffle, making it easier for the baffle to detach from the concrete after it has solidified. Furthermore, by selecting a suitable bending plate according to the actual situation and bending it along the bending groove towards the vertical support plate, reinforcing bars can be inserted from the bend. The reinforcing bars extend from the already poured concrete towards the post-cast strip, passing through the bend of the bending plate and the spacer channel to the space between the two vertical support plates. When pouring the concrete structure in the post-cast strip, the reinforcing bars can be directly cast into the strip, further improving the bond strength between the post-cast strip concrete and the already poured concrete. Moreover, the bending operation of the bending plate is simple, greatly reducing the difficulty for workers. Attached Figure Description

[0043] To facilitate a clear understanding of the technical means, inventive features, objectives, and effects of this invention, the following description is provided in conjunction with... Figure 1-7 The invention will be further illustrated as shown.

[0044] like Figure 7 As shown, the basement post-cast strip structure includes a vertical support plate 10, a horizontal support plate 11, an upper mating block 12, a lower mating block 13, a post-cast strip baffle 20, a drainage channel 24, and an outward-facing plate 25. Two vertical support plates 10 are arranged side-by-side, extending horizontally. Each vertical support plate 10 has several threaded holes 19 arranged side-by-side in the direction of its extension. A spacer channel 26 is provided between adjacent threaded holes 19. The horizontal support plate 11 is located on the side of the vertical support plate 10 where the threaded holes 19 are located. A connecting threaded post 18 is provided on the horizontal support plate 11, extending through the threaded hole 19 to fix the horizontal support plate 11 and the vertical support plate 10 together. The lower mating block 13 is fixed to the side of the vertical support plate 10 that is far from the horizontal support plate 11. The upper mating block 12 is fixed on the horizontal support plate 11 and the upper mating block 12 and the lower mating block 13 are vertically aligned. The extension direction of the upper mating block 12 and the lower mating block 13 is the same as that of the vertical support plate 10, and the upper mating groove 14 and the lower insertion groove 15 are respectively opened on the opposite surfaces of the upper mating block 12 and the lower mating block 13.

[0045] like Figure 2 and Figure 7 As shown, the post-cast strip baffle 20 extends in the same direction as the vertical support plate 10, with one end inserted into the lower insertion groove 15 and engaging with it. The other end of the post-cast strip baffle 20 extends towards the upper mating groove 14, and there is a deformation interval between the post-cast strip baffle 20 and the vertical support plate 10. A plurality of drainage channels 24 are provided on the post-cast strip baffle 20, extending vertically along the post-cast strip baffle 20. One end of the outward-flaring plate 25 is fixed to the opening of the drainage channel 24, and the other end of the outward-flaring plate 25 extends obliquely from the post-cast strip baffle 20 towards the vertical support plate 10 into the deformation interval and abuts against the vertical support plate 10. A number of external protrusions 23 are fixedly distributed on the side of the post-pouring strip baffle 20 away from the vertical support plate 10. A number of bent plates 21 extending into the upper mating groove 14 are fixed at the end of the post-pouring strip baffle 20 facing the upper mating groove 14. The bent plates 21 are arranged side by side at equal intervals facing the extension direction of the vertical support plate 10. A bending groove 22 is opened on the side of the bent plate 21 facing the vertical support plate 10.

[0046] like Figure 2-4As shown, a maintenance port 16 is vertically oriented through the horizontal support plate 11, and a maintenance cover plate 17 is detachably fixed to the maintenance port 16. Two opposite end faces of the maintenance port 16, extending in the same direction as the vertical support plate 10, have sliding grooves 30 extending in the same direction as the vertical support plate 10. Sliding blocks 31 are slidably disposed within the sliding grooves 30, and a connecting rod 32 is fixedly connected between the two sliding blocks 31. One end of the sliding block 31 extends into the maintenance port 16, and a placement block 33 is fixedly disposed at the end of the sliding block 31 extending into the maintenance port 16. The placement block 33 is L-shaped, with its vertical end extending vertically towards the side away from the horizontal support plate 11 and between the two vertical support plates 10. The horizontal end of the placement block 33 extends in the same direction as the sliding groove 30, and an arc-shaped groove is formed on the side of the horizontal end of the placement block 33 facing the horizontal support plate 11. A flipping block 35 is hinged to the side of the horizontal end of the placement block 33 away from the vertical end. An abutment block 36 is fixedly installed on the flipping block 35. The abutment block 36 moves toward the vertical end of the placement block 33 or away from the vertical end of the placement block 33 during the flipping of the flipping block 35 along the hinge. When the abutment block 36 is in its extreme position moving towards the vertical end of the placement block 33, and an adjustment end 37 is fixedly installed on the side away from the horizontal end of the placement block 33, the adjustment end 37 is located at the end of the abutment block 36 away from the flipping block 35, and both ends of the adjustment end 37 extend towards the two vertical support plates 10 respectively. A connecting ring 38 is detachably fitted on the adjustment end 37. One end of the connecting ring 38 can be directly fitted onto the end of the reinforcing bar when the reinforcing bar is placed in the arc groove. After the flipping block 35 is flipped along the intersection so that the abutment block 36 abuts against the reinforcing bar, the other end of the connecting ring 38 is fitted onto the adjustment end 37. At this time, the connecting ring 38 can play a certain limiting role in the flipping of the flipping block 35 through its connection with the adjustment end 37. At the same time, since there is friction between the abutment surface of the flipping block 35 and the placement block 33 at the hinge, the friction is greater than the pressure on the abutment block 36 when the supplementary reinforcing bar 40 shakes. Therefore, the flipping block 35 cannot flip itself without the intervention of external force. An elastic strip 34 is fixedly installed on one side of the placement block 33 facing the sliding groove 30. The elastic strip 34 extends toward the vertical support plate 10. The elastic strip 34 is made of a material that can undergo elastic deformation, and only the end part of the elastic strip 34 can contact the end of the reserved steel bar.

[0047] like Figure 1-2 As shown, the reinforcing bars placed in the arc-shaped groove of the placement block 33 are supplementary reinforcing bars 40, and the reserved reinforcing bars passing through the interval channel 26 are the basic reinforcing bars 41. The two ends or one end of the supplementary reinforcing bars 40 are fixed to the basic reinforcing bars 41 by binding to achieve the effect of extending the length of the reinforcing bars. One end of the basic reinforcing bars 41 extends into the post-pouring strip, and the other end of the basic reinforcing bars 41 extends to the outside of the post-pouring strip and is poured with the concrete mortar first.

[0048] like Figure 5 and Figure 6 As shown, when constructing the post-pouring strip structure, the location of the post-pouring strip is first determined according to the construction situation. Then, a vertical support plate 10 is vertically fixed at the edge of the post-pouring strip, making the vertical support plate 10 perpendicular to the pouring plane. Next, a horizontal support plate 11 is placed on the two vertical support plates 10, and the horizontal support plate 11 abuts against the vertical support plate 10. Finally, a connecting threaded post 18 is screwed into the mating threaded hole 19 to fix the horizontal support plate 11 and the vertical support plate 10 together. Then, one end of the post-pouring strip baffle 20 is inserted into the lower insertion groove 15 through the end of the vertical support plate 10 to complete the insertion. The post-pouring strip baffle 20 is slid within the lower insertion groove 15 until its edge is flush with the vertical support plate 10. Several baffles are installed along the extension direction of the post-pouring strip, ensuring the extension ends of adjacent vertical support plates 10 abut against each other. Concrete mortar is then poured in a direction away from the two vertical support plates 10. The concrete mortar is blocked by the post-pouring strip baffle 20, generating pressure on it towards the vertical support plate 10. Under this pressure, the post-pouring strip baffle 20 tilts towards the vertical support plate 10, and the outward-turning plates 25 gradually... As the concrete is gradually pressed into the drainage channel 24, one end of the post-cast strip baffle 20 inserted into the lower insertion groove 15 bends, and the end of the post-cast strip baffle 20 facing the upper mating block 12 abuts against the surface of the vertical support plate 10. After the end of the post-cast strip baffle 20 abuts against the vertical support plate 10, the post-cast strip baffle 20 no longer tilts and forms a triangular support structure with the vertical support plate 10. At this time, the end of the concrete mortar facing the vertical support plate 10 forms a slope under the tilting action of the post-cast strip baffle 20. After the post-cast strip structure is removed, when pouring concrete mortar into the post-cast strip, compared with traditional construction, the concrete mortar is poured into the post-cast strip. Since the height of the poured concrete is fixed, the inclined surface has a larger area than the vertical surface. Therefore, it can increase the contact area between the post-pouring concrete and the already poured concrete, increasing the bonding surface between the two parts of concrete and improving the bonding strength. At the same time, due to the inclined surface structure of the edge of the already poured concrete, after the post-pouring concrete is poured, the edge of the post-pouring concrete abuts against the edge of the already poured concrete. At this time, the edge of the already poured concrete can restrict the post-pouring concrete, ensuring the stability of the post-pouring concrete and improving the bonding stability between the two.

[0049] Several external protrusions 23 are provided on the post-pouring strip baffle 20, which can improve the surface roughness of the post-pouring strip baffle 20, making it easier for the post-pouring strip baffle 20 to separate from the concrete after the concrete has solidified. In addition, a bending plate 21 is selected at an appropriate position according to the actual situation, and the bending plate 21 is bent along the bending groove 22 toward the vertical support plate 10. At this time, a steel bar can be inserted from the bending point. The steel bar extends from the already poured concrete toward the post-pouring strip and passes through the bending point of the bending plate 21 and the interval channel 26 in sequence, extending to the space between the two vertical support plates 10. At this time, when pouring the concrete structure in the post-pouring strip, the steel bar can be directly poured into the post-pouring strip, which is conducive to further improving the bonding strength between the post-pouring strip concrete and the already poured concrete. Moreover, the operation of bending the bending plate 21 is simple, which greatly reduces the difficulty of operation for workers.

[0050] By opening the inspection port 16, workers can conduct regular inspections and surveys of the post-pouring strip after the horizontal support plate 11 is installed, without having to dismantle the post-pouring strip structure, thus improving the convenience of inspection for workers.

[0051] The fixed groove can hold reinforcing bars, and the two ends of the reinforcing bars are respectively matched with the arc-shaped grooves on the two side placement blocks 33. At this time, the arc-shaped grooves can slightly restrict the movement of the reinforcing bars. By pushing the connecting rod 32 to slide along the extension direction of the sliding groove 30, the sliding blocks 31 on both sides can be moved at the same time, thereby causing the sliding blocks 31 to move the placement blocks 33, thus achieving the purpose of making the reinforcing bars move smoothly along the extension direction of the vertical support plate 10. When the reinforcing bars move to the reserved reinforcing bars that pass through the interval channel 26, the connecting rod 32 is stopped. Then, the worker can pick up the reinforcing bars placed on the placement blocks 33 through the inspection port 16 and tie them to the reserved reinforcing bar ends to achieve the purpose of extending the length of the reinforcing bars. There is no need to disassemble the horizontal support plate 11, which greatly reduces the difficulty of extending the length of the reinforcing bars and helps to improve construction efficiency.

[0052] The flipping block 35 is flipped along the hinge. When a steel bar is placed in the arc groove of the placement block 33, the abutting block 36 can be flipped towards the placement block 33 and abut against the steel bar. At this time, the abutting block 36 can further restrict the movement of the steel bar and greatly improve the stability of the steel bar during movement.

[0053] By fitting a connecting ring 38 onto the adjusting end 37, during the above process, when the reinforcing bar placed on the placement block 33 moves to the reserved reinforcing bar, the connecting ring 38 can be removed from the adjusting end 37, and one end of the connecting ring 38 can be fitted onto the reserved reinforcing bar, while the other end of the connecting ring 38 can be fitted onto the reinforcing bar located in the arc groove of the placement block 33. At this time, the two reinforcing bars are temporarily connected by the connecting ring 38. At this time, the worker does not need to hold the reinforcing bar to keep it stable, and the worker can tie the two reinforcing bars with both hands, which greatly improves the convenience of the worker's operation.

[0054] During construction, the location where the length of the reinforcing bar needs to be extended often needs to be adjusted according to the actual construction situation. Therefore, when extending the reinforcing bar in the above process, the worker needs to first find the location of the reserved reinforcing bar. However, the reserved reinforcing bar is blocked by the horizontal support plate 11, making it difficult for the worker to quickly find the location of the reserved reinforcing bar. During the sliding of the sliding block 31, the elastic strip 34 can collide with the reserved reinforcing bar. At this time, when the worker pushes the connecting rod 32, resistance will be generated, which will make the worker clearly aware of the location of the reserved reinforcing bar, thus enabling the worker to quickly find the reserved reinforcing bar and greatly improve the worker's construction efficiency. Furthermore, through the contact between the elastic strip 34 and the reserved reinforcing bar, the reserved reinforcing bar and the reinforcing bar placed on the placement block 33 can be in approximately the same vertical plane. At this time, the worker can complete the operation of putting the two ends of the connecting ring 38 onto the two reinforcing bars more quickly and conveniently, further improving the worker's efficiency in extending the reinforcing bar.

[0055] Construction methods for basement post-cast strip structures, including:

[0056] S1: Place two vertical support plates 10 vertically on opposite sides of the post-cast strip. Fix the vertical support plates 10 to the mounting surface by pre-embedding steel bars in the ground or using limiting structures such as steel nails. Place the horizontal support plate 11 on the upper end of the vertical support plates 10.

[0057] S2: Use the connecting threaded post 18 to fix the horizontal support plate 11 and the vertical support plate 10 together, and insert the post-pouring strip baffle 20 into the downward insertion groove 15, and the outward flip plate 25 abuts against the surface of the vertical support plate 10.

[0058] S3: When the concrete mortar has solidified, if it is necessary to extend the reserved steel bars to improve the bonding strength between the post-cast concrete and the already poured concrete, remove the inspection cover plate 17, then place the appropriate steel bars into the arc groove on the placement block 33, and then push the connecting rod 32 through the above process to find the reserved steel bars in the appropriate position.

[0059] S4: After locating the reserved reinforcing bar, remove the connecting ring 38 from the adjusting end 37 and connect it to the end of the reserved reinforcing bar, so that the reserved reinforcing bar and the end of the reinforcing bar placed in the arc groove are connected. Then, manually tie the ends of the two reinforcing bars. During the tying process, the tying position can be adjusted by adjusting the axial position of the reinforcing bar placed on the placement block 33. When the end of the reinforcing bar extends through the interval channel 26 to the outside of the post-pouring strip, the two reinforcing bars can be tied directly on the side of the post-pouring strip baffle 20 away from the vertical support plate 10. At the same time, the two reinforcing bars are tied at the end of the reserved reinforcing bar that extends to the post-pouring strip, thereby improving the tying strength of the reinforcing bars.

[0060] S5: Repeat steps S3 and S4 to extend and tie all the reserved steel bars that need to be extended;

[0061] S6: Pour concrete mortar onto one side of the vertical support plate 10 where the post-pouring strip baffle 20 is installed. The post-pouring strip baffle 20 blocks the concrete mortar, preventing it from penetrating the post-pouring strip.

[0062] S7: After the concrete mortar has solidified, remove the threaded column 18 and separate the horizontal support plate 11 from the vertical support plate 10.

[0063] S8: Move the vertical support plate 10 toward the side away from the concrete, and the vertical support plate 10 will cause the post-pouring strip baffle 20 to separate from the concrete.

[0064] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of the invention, all of which fall within the scope of protection claimed by the present invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.
