Description

Technical Field

[0001] This invention relates to the field of construction technology for water-stop steel plate through-column, and in particular to a prefabricated welded water-stop steel plate column stirrup through-column structure, tooling and construction method. Background Technology

[0002] In building construction, the treatment of construction joints between exterior walls and columns is a crucial aspect of waterproofing for structures such as basements and water tanks that require waterproofing. To prevent groundwater seepage along these joints, the common practice is to install water-stop steel plates. Traditionally, the water-stop steel plate is placed in the middle of the column cross-section, and the column stirrups need to be disconnected and welded to the water-stop steel plate or connected in other ways to achieve the restraining effect of the stirrups on the column concrete. Existing technologies involved include:

[0003] 1. A method for connecting stirrups and waterstop steel plates for basement exterior wall columns, disclosed in publication number CN113737864A, discloses step three: spot welding the back of the steel plate waterstop to the vertical reinforcement, and when welding and fixing, the concave side of the steel plate waterstop faces the water-facing side of the basement exterior wall; step four: after the steel plate waterstop is positioned and fixed, the stirrups at the break point of the column member by the steel plate waterstop are separated into two stirrups, and the two stirrups are fixedly connected to the end face of the steel plate waterstop respectively;

[0004] 2. A water-stop steel plate through-column structure and method, disclosed in CN114277854B, includes a reinforced steel mesh column and a water-stop steel plate. The reinforced steel mesh column is composed of longitudinal bars and stirrups, the stirrups including closed stirrups and colliding stirrups. The water-stop steel plate is positioned within the reinforced steel mesh column at the location of the colliding stirrups. The colliding stirrups include a first bent steel bar and a second bent steel bar. A clamp is provided on each side of the water-stop steel plate, the clamp having a first clamping part and a second clamping part. One end of the first bent steel bar is fixed to the first clamping part of the clamp, and one end of the second bent steel bar is fixed to the second clamping part of the clamp. The other end of the first bent steel bar is fixed to the first clamping part of another clamp, and the other end of the second bent steel bar is fixed to the second clamping part of another clamp.

[0005] In the aforementioned existing technologies, there are two ways to connect the waterstop steel plate and the broken column stirrups. The first method is to weld the waterstop steel plate and the broken column stirrups on the construction site. The second method is to clamp the waterstop steel plate and the broken column stirrups on the construction site using clamps. Both methods require on-site adjustment and assembly of the broken column stirrups and waterstop steel plate, which is difficult and inefficient. On-site welding can cause weld slag to fall onto the construction site, affecting its cleanliness. Using clamps to connect the column stirrups and waterstop steel plate results in a small gap between the clamp and the column stirrup, making it difficult for concrete to enter the gap, leading to... The concrete is not poured densely, and the clamps are mechanically connected by bolts and nuts. During concrete pouring and vibration, they may loosen due to vibration or impact, causing displacement between the stirrups and the waterstop steel plate. This affects the restraint effect of the stirrups and the waterstop performance of the steel plate, making the construction joint prone to leakage. Furthermore, the existing stirrups of the split column are simple n-shaped structures. When they are connected to the waterstop steel plate, the contact area between the stirrups and the steel plate is straight, which may cause the stirrups and the steel plate to be non-perpendicular. Moreover, relying solely on manual positioning of the stirrups and the steel plate will result in a height difference between the stirrups on both sides of the waterstop steel plate, reducing the load-bearing capacity of the structural column at this section and lowering the safety factor. In view of this, this case was developed after in-depth research into the above problems. Summary of the Invention

[0006] The purpose of this invention is to solve the above-mentioned problems by designing a prefabricated welded waterstop steel plate column stirrup through-column structure, tooling, and construction method. This solves the problems of the difficult and inefficient on-site adjustment and assembly of disconnected column stirrups and waterstop steel plates, which is difficult to perform. Furthermore, on-site welding results in weld slag falling onto the construction site, affecting cleanliness. While using clamps to connect the column stirrups and waterstop steel plates creates small gaps between the clamps and the stirrups, making it difficult for concrete to enter and resulting in incomplete concrete pouring. Additionally, the clamps are connected by bolts and screws... The mechanical connection of the mother column may loosen due to vibration or impact during concrete pouring and vibration, causing displacement between the stirrups and the waterstop steel plate. This affects the restraint effect of the stirrups and the waterstop performance of the steel plate, making the construction joint prone to leakage. Furthermore, the existing stirrups of the split column are simple n-shaped structures. When they are connected to the waterstop steel plate, the contact area between the stirrups and the waterstop steel plate is straight, which may cause the stirrups and the waterstop steel plate to be non-perpendicular. Moreover, relying solely on manual positioning of the stirrups and the waterstop steel plate can lead to a height difference between the stirrups on both sides of the waterstop steel plate, resulting in a reduction in the load-bearing capacity of the structural column at this section and a low safety factor.

[0007] The technical solution of the present invention to achieve the above objectives is as follows: a method for constructing precast welded waterstop steel plate columns with stirrups inserted through the column, comprising the following steps:

[0010] Step 3: Take the new multi-bend column stirrup and fix it on the clamping fixture. Move the clamping fixture so that the multi-bend column stirrup is movably attached to the other side wall of the column inner plate waterstop.

[0021] Preferably, the base includes a perforated zigzag base, which is disposed on one side of the retaining edge.

[0050] Example 1:

[0051] A method for constructing precast welded waterstop steel plate columns with stirrups inserted through the column includes the following steps:

[0052] Step 1: Take a section of waterstop steel plate as the column inner plate waterstop 1. The length of the column inner plate waterstop 1 is greater than the length of the column section. Prepare a prefabricated welding waterstop steel plate column stirrup insertion fixture. The prefabricated welding waterstop steel plate column stirrup insertion fixture includes a fixing fixture and a clamping fixture. Fix the column inner plate waterstop 1 on the fixing fixture.

[0053] Step 2: Take out the stirrups. Use a steel bar bending tool to bend the stirrups into multi-bend column stirrups 2. The size design is made according to the actual building needs and is not limited here. Fix the multi-bend column stirrups 2 on the clamping fixture. Adjust the clamping fixture so that the multi-bend column stirrups 2 can be moved to fit against the target height of one side wall of the waterstop 1 of the column inner plate. Use a welding tool to weld the multi-bend column stirrups 2 to the waterstop 1 of the column inner plate.

[0054] Step 3: Take the new multi-bend column stirrup 2 and fix it on the clamping fixture. Move the clamping fixture so that the multi-bend column stirrup 2 is movably fitted against the other side wall of the waterstop 1 on the inner plate of the column. Use welding tools to weld the multi-bend column stirrup 2 to the waterstop 1 on the inner plate of the column. At this time, the multi-bend column stirrups 2 on both sides form a rectangular structure on both sides of the waterstop 1 on the inner plate of the column. Through the clamping fixture, the multi-bend column stirrups 2 on both sides can be aligned and welded at the same height. The design eliminates the error caused by manually adjusting the relative height position of the multi-bend column stirrups 2 on both sides. The remaining multi-bend column stirrups 2 are welded to both sides of the column inner plate waterstop 1 by clamping fixtures according to the longitudinal reinforcement spacing of the column during the building construction process, until all the multi-bend column stirrups 2 required by the drawings are welded to the column inner plate waterstop 1 to form a prefabricated component. The welding length between the two ends of the multi-bend column stirrups 2 on each side and the column inner plate waterstop 1 is not less than 10d and not more than 100mm, where d is the diameter of the stirrup.

[0055] Step 4: Tie the horizontal and positioning bars of the column on the outside of the basement, and then tie the longitudinal bars. First, tie the column stirrups at the bottom of the longitudinal bars. When the column stirrups at the bottom of the longitudinal bars are tied to the bottom of the precast components shown on the drawings, take the precast components and put them on the longitudinal bars. Tie the multi-bend column stirrups 2 to the longitudinal bars to fix the precast components. Then, continue to tie the column stirrups on top of the precast components.

[0056] Step 5: Tie the horizontal and positioning bars of the column on the outside of the basement, and then tie the longitudinal bars. Confirm the installation height and position of the prefabricated components according to the requirements of the drawings.

[0057] Step 6: Tie the column stirrups at the bottom of the longitudinal reinforcement. When the column stirrups at the bottom of the longitudinal reinforcement are tied to the bottom of the precast component shown on the drawing, take the precast component and put it on the longitudinal reinforcement. Tie the multi-bend column stirrup 2 to the longitudinal reinforcement to fix the precast component. Then continue to tie the column stirrups above the precast component.

[0058] Step 7: Connect the inner column waterstop 1 to the outer wall waterstop steel plate by overlapping. Full welding is performed on the overlapping area, and the overlap length is not less than 100mm.

[0059] Step 8: Set up the outer formwork system for the foundation raft slab pouring space, the basement foundation beam pouring space, and the basement corner column lower pouring space. Then, in the above spaces, complete the concrete pouring in one go, so that the top surface of the poured concrete is set on the horizontal plane where the horizontal construction joint is located. At this time, the lower half of the waterstop steel plate is submerged in the poured concrete.

[0060] Step 8: Set up the concrete pouring formwork for the upper part of the basement corner column above the waterstop steel plate, and pour concrete in the upper part of the basement corner column, so that the 90-degree turn of the waterstop steel plate can block the horizontal construction joint generated by the two concrete pours.

[0061] Example 2:

[0062] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-4 As shown, a prefabricated welded waterstop steel plate column stirrup through-column structure is presented.

[0063] A prefabricated welded waterstop steel plate column stirrup through-column structure includes four corner bars 3, and multiple side bars 4 are provided between each corner bar 3. Prefabricated components are fitted on the four corner bars 3 and the multiple side bars 4 along the longitudinal direction.

[0064] It should be noted that the number of edge reinforcement 4 and the spacing between the four corner reinforcement 3 and the multiple edge reinforcement 4 are set according to the architectural drawings. The four corner reinforcement 3 and the multiple edge reinforcement 4 are inserted according to the drawings.

[0065] Specifically, the prefabricated components include a waterstop 1 in the inner slab of the column, and multiple stirrup groups are arranged longitudinally at equal intervals on both sides of the waterstop 1 in the inner slab of the column, and each stirrup group includes at least one multi-bend column stirrup 2.

[0066] It should be noted that when the number of multiple edge bars 4 is greater than three, each side and each layer of the inner plate waterstop 1 of the column is provided with two multi-bend column stirrups 2, and one multi-bend column stirrup 2 covers one corner bar 3 and three edge bars 4, while the other multi-bend column stirrup 2 covers the three edge bars 4 and another corner bar 3 on the same side.

[0067] Specifically, the multi-bend column stirrup 2 includes an n-shaped bar 21, which is set perpendicular to the waterstop 1 of the column inner plate. Both ends of the n-shaped bar 21 are horizontally extended by a welded bar 23 through the first arc segment 22. One end of the welded bar 23 is vertically extended by a leveling bar 25 through the second arc segment 24. The leveling bar 25 and the welded bar 23 are attached to the side wall of the waterstop 1 of the column inner plate.

[0068] It should be noted that when making the multi-bend column stirrup 2, the n-shaped bar 21, the first arc segment 22, the welded bar 23, the second arc segment 24, and the leveling bar 25 can be formed by a steel bar bending machine. The n-shaped bar 21 is used to cover the edge bar 4 and the corner bar 3. The welded bar 23, the second arc segment, and the leveling bar 25 form a plane. The n-shaped bar 21 is perpendicular to the plane it forms. Therefore, when the multi-bend column stirrup 2 is attached to the side wall of the column inner plate waterstop 1 by the welded bar 23, the second arc segment, and the leveling bar 25, the n-shaped bar 21 is set perpendicular to the column inner plate waterstop 1. There is no need for the operator to manually control the perpendicularity between the n-shaped bar 21 and the column inner plate waterstop 1. The operator welds the welded bar 23 to the column inner plate waterstop 1.

[0069] Example 3:

[0070] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 5-11 As shown, a tooling for inserting stirrups into prefabricated welded waterstop steel plate columns is provided.

[0071] A prefabricated welded waterstop steel plate column stirrup insertion tooling includes a fixing tooling and a clamping tooling;

[0072] Specifically, the fixed fixture includes at least one support frame 5, the column inner plate waterstop 1 is movably installed on the support frame 5, and the front end of the support frame 5 is provided with an adjustment pressing part 6, which is movably attached to the water-facing surface of the column inner plate waterstop 1.

[0073] It should be noted that multiple support frames 5 can be set up in a straight line. The waterstop 1 of the inner plate of the column is placed on the multiple support frames 5. The adjusting gap pressing part 6 is set at the front end of the support frame 5 and together with the support frame 5, it fixes the waterstop 1 of the inner plate of the column.

[0074] Specifically, the clamping fixture includes an adjustable base 7, on which a clamping component 8 is movably mounted, and a multi-bend column stirrup 2 is mounted on the clamping component 8;

[0075] It should be noted that the clamping member 8 is used to fix the multi-bend column stirrup 2, and the clamping member 8 can move the multi-bend column stirrup 2 on the adjustable seat 7.

[0076] Specifically, each support frame 5 includes at least two perforated legs 51, one end of the perforated leg 51 is equipped with an L-shaped frame 52, one end of the L-shaped frame 52 extends vertically upward with a retaining edge 53, at least two L-shaped ribs 54 are installed on the inner wall of the L-shaped frame 52, and the back water surface of the column inner plate waterstop 1 is movably attached to the L-shaped ribs 54.

[0077] It should be noted that the support frame 5 is fixed to the welding workbench or other flat surface by the perforated leg 51. The perforated leg 51 can be connected to the welding workbench or other flat surface by inserting threaded connectors. The perforated leg 51 is used to support the L-shaped frame 52. The waterstop 1 of the inner plate of the column is placed on the L-shaped protrusion 54 inside the L-shaped frame 52. The retaining edge 53 is used to prevent the waterstop 1 of the inner plate of the column from falling out of the L-shaped frame 52 and plays a limiting role. The water-facing surface of the waterstop 1 of the inner plate of the column faces the retaining edge 53.

[0078] Specifically, the adjustable pressing component 6 includes a base 61, on which a pusher 62 is movably installed along the vertical direction of the waterstop 1 of the inner plate of the column. A threaded column 63 is installed on the upper wall of the pusher 62, and the threaded column 63 movably passes through the base 61. A fixing nut 64 is movably fitted on the threaded column 63 and is movably attached to the base 61. A bottom pressure plate 65 is installed at one end of the pusher 62. A first screw 66 is movably inserted into the pusher 62. A horizontal T-shaped lifting plate 68 is installed on the first screw 66 through a first movable nut 67. Both the horizontal T-shaped lifting plate 68 and the bottom pressure plate 65 are movably attached to the water-facing surface of the waterstop 1 of the inner plate of the column.

[0079] It should be noted that, due to the different heights of the waterstop 1 in the inner column plate, the plane height of the middle part of the waterstop 1 in the inner column plate is also different. Preferably, and further, one end of the first screw 66 is provided with a bending handle 631, and two second guide rods 69 are installed on the lower wall of the seat plate 71. The two second guide rods 69 are movably inserted into the push frame 62. The two second guide rods 69 are used to guide and limit the horizontal T-shaped lifting plate 68. The horizontal T-shaped lifting plate 68 and the second guide rods 69 can be connected by a linear bearing. By rotating the first screw... The screw 66 drives the first moving nut 67 to move the horizontal T-shaped lifting plate 68 along the axial direction of the first screw 66, thereby adjusting the height of the horizontal T-shaped lifting plate 68. The first screw 66 can be movably inserted into the push frame 62 through the rotating shaft bearing, so that the horizontal T-shaped lifting plate 68 can be aligned with the plane of the middle part of the column inner plate waterstop 1. In particular, the column inner plate waterstop 1 with a bending structure in the middle is placed in the support frame 5. By adjusting the height of the horizontal T-shaped lifting plate 68, the bending structure in the middle part of the column inner plate waterstop 1 can be avoided, and then it is pushed.

[0080] Specifically, the base 61 includes a perforated zigzag base 611, which is located on one side of the sidewall 53. A C-shaped frame 612 is fixedly installed on the inner bottom surface of the perforated zigzag base 611. A first elongated hole 613 is opened on the upper wall of the C-shaped frame 612. A threaded post 63 is movably inserted through the first elongated hole 613. A fixing nut 64 is movably attached to the upper wall of the C-shaped frame 612. At least two limiting rods 621 are installed on the lower wall of the pusher frame 62. A second elongated hole 622 matching the limiting rods 621 is opened on the perforated zigzag base 611. An anti-detachment block 623 is installed on the lower wall of the limiting rods 621. The anti-detachment block 623 is movably attached to the inner top surface of the perforated zigzag base 611.

[0081] It should be noted that the base 61 is fixed to the welding workbench or other flat surface by a perforated bracket 611. The perforated bracket 611 can be connected to the welding workbench or other flat surface by inserting threaded connectors. By pushing the pusher 62, the horizontal T-shaped lifting plate 68 and the bottom pressure plate 65 are pressed onto the waterstop 1 of the inner plate of the column. When the pusher 62 moves between the perforated bracket 611 and the C-shaped frame 612, the threaded column 63 moves in the first elongated hole 613, and the limiting rod 621 moves in the second elongated hole 622. The limiting rod 621 is used to prevent the pusher 62 from rotating around the threaded column 63. Then, the fixing nut 64 on the threaded column 63 is tightened, so that the fixing nut 64 is pressed onto the upper wall of the C-shaped frame 612. The position of the pusher 62 is fixed by friction, thus fixing the waterstop 1 of the inner plate of the column. The anti-detachment block 623 is used to prevent the limiting rod 621 from detaching from the second elongated hole 622.

[0082] Specifically, the clamping component 8 includes a support plate 81, two limiting posts 82 are symmetrically installed on the upper wall of the support plate 81, n-shaped ribs 21 are movably attached to the upper wall of the support plate 81 and the outer wall of the two limiting posts 82, clamping plates 83 are movably fitted on the two limiting posts 82, a second screw 84 is movably inserted into the support plate 81, a second movable nut 85 is movably fitted into the second screw 84, and the second movable nut 85 is fixedly inserted into the clamping plate 83;

[0083] It should be noted that when the multi-bend column stirrup 2 needs to be fixedly installed on the clamping member 8, the second screw 84 is rotated. Under the limiting guidance of the limiting post 82, the second moving nut 85 drives the clamping plate 83 to move along the axial direction of the second screw 84. The multi-bend column stirrup 2 can be placed between the support plate 81 and the clamping plate 83, and the n-shaped rib 21 is attached to the two limiting posts 82 to limit the relative position between the n-shaped rib 21 and the clamping member 8. Then, the second screw 84 is rotated in the opposite direction to lower the clamping plate 83 until the multi-bend column stirrup 2 is clamped and fixed. The clamping plate 83 and the limiting post 82 can be connected by a linear bearing, and the second screw 84 and the support plate 81 can be connected by a rotary bearing.

[0084] Specifically, the adjustable seat body 7 includes a seat plate 71, a handle 72 installed on the upper wall of the seat plate 71, a top plate 73 installed at one end of the handle 72, a support 74 installed on the seat plate 71, a third screw 75 movably inserted into the support 74, the third screw 75 movably inserted into the top plate 73, and a third movable nut 76 fixedly inserted into the support plate 81, the third movable nut 76 movably fitted onto the third screw 75;

[0085] It should be noted that the operator can hold the handle 72 and transfer the clamping fixture and the multi-bend column stirrup 2 to the side of the column inner plate waterstop 1 fixed by the fixing fixture. The clamping fixture is placed on the welding workbench or other flat surface through the seat plate 71. Preferably, and further, two first guide rods 77 are installed on the seat plate 71, and the support plate 81 is movably fitted onto the two first guide rods 77. The support plate 81 and the first guide rods 77 can be connected by a linear bearing. By rotating the third screw 75, under the limiting guidance of the two first guide rods 77, the third moving nut 76 drives the support plate 81 to move along the axial direction of the third screw 75, so that the multi-bend column waterstop 2 is fixed by the handle 72. Once the relative positions of the multi-bend column stirrup 2 and the waterstop 1 of the inner column plate are reached, the clamping fixture is adjusted to ensure that the multi-bend column stirrup 2 and the waterstop 1 of the inner column plate are in close contact. The operator then welds them together. Afterward, the operator rotates the second screw 84 to raise the clamping plate 83, loosening the multi-bend column stirrup 2, removing the clamping fixture, and then installing a new multi-bend column stirrup 2 at the corresponding position of the welded multi-bend column stirrup 2. This new stirrup is then fixed to the clamping member 8. The clamping fixture and the multi-bend column stirrup 2 are transferred to the other side of the waterstop 1 of the inner column plate to achieve equal-height clamping and welding. The support 74 and the top plate 73 are connected to the third screw 75 via a rotating bearing.

[0086] As a preferred and further option, one end of the first screw 66 is provided with a bending handle 631, which the operator can hold to push and pull the push frame 62.

[0087] Rubber anti-slip pads can be installed on the L-shaped protruding rib 54, the bottom pressure plate 65, the horizontal T-shaped lifting plate 68, the support plate 81, and the clamping plate 83 to increase the friction between the tooling and the waterstop 1 of the inner plate of the column and the multi-bend column stirrup 2, and to prevent mutual wear.

[0088] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
