Description

Technical Field

[0001] This invention relates to the technical field of water-stop structure construction, specifically to the water-stop construction method and structure at the joint of the skip-compartment method. Background Technology

[0002] In the process of pouring large-area concrete, the skip-pour method is increasingly used. The skip-pour method, through block planning, inter-block construction, layered pouring, and integral molding, successfully eliminates the post-pouring strip and has a significant effect on crack resistance and seepage prevention for large-volume concrete that is ultra-long, ultra-wide, and ultra-thick.

[0003] During the skip-containment method of construction, construction joints will form between the compartments. The placement of these construction joints is a key factor affecting the construction progress and quality. Currently, the method used for this method involves welding ladder-like reinforcement bars to steel bars, binding them with wire mesh, and welding them to the top and bottom of the waterstop steel plate. This method is costly, time-consuming, and the wire mesh is difficult to remove, easily creating leakage paths. Furthermore, at the junction with the steel bars, only wooden supports are used to connect the top to the ladder-like reinforcement bars, ultimately creating a gap with the same diameter as the steel bars. This requires chiseling during formwork removal, increasing the workload. Summary of the Invention

[0004] The present invention aims to solve the above problems, thereby providing a method and structure for waterproofing construction at joints using the skip-fill method.

[0005] The present invention solves the aforementioned problem by adopting the following technical solution:

[0006] The water-stopping structure at the joint of the skip-concrete method includes: a concrete mortar base of the same strength, which covers the reinforcing steel bars at the joint of the skip-concrete method. The characteristic is that a water-stopping steel plate assembly is fixed above the concrete mortar base. The water-stopping steel plate assembly includes a vertical plate and a horizontal water-stopping steel plate. The vertical plate and the water-stopping steel plate have a cross-shaped structure. The vertical plate at the upper end of the water-stopping steel plate is provided with multiple horizontal reinforcing bar grooves for placing the upper layer of reinforcing steel bars.

[0007] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art:

[0008] The aforementioned water-stopping structure uses a concrete mortar base of the same strength as the reinforcing steel as a base to fix the water-stopping steel plate, which is both sturdy and convenient for construction. The vertical plate and the water-stopping steel plate have a cross-shaped structure. The vertical plate supports the water-stopping steel plate, and multiple steel bar grooves are cut at the upper end of the vertical plate of the water-stopping steel plate assembly to fix the upper layer of reinforcing steel in the grooves. While the water-stopping steel plate stops the water, this assembly also provides support for the upper layer of reinforcing steel. During pouring, one side of the vertical plate is poured first, and the other side is poured after the concrete has solidified, which effectively solves the problem of water-stopping at the joints in the skip-pour method of construction. This structure can effectively improve the water-stopping effect, speed up the construction progress, and improve the quality of the project.

[0009] As a preferred embodiment, a further technical solution of the present invention is:

[0010] The upright plate includes an upper upright plate, an insertable upright plate, and a lower upright plate. The lower upright plate is fixed between a concrete mortar base of the same strength and a water-stop steel plate. The upper upright plate is located at the upper end of the water-stop steel plate. The insertable upright plate is inserted and fixed to the upper end of the upper upright plate. The lower end of the insertable upright plate has a steel bar groove with an inverted U-shaped structure. The insertable upright plate and the upper upright plate near the steel bar groove are provided with corresponding upper and lower fixing blocks, and fixing clips are inserted into the fixing blocks.

[0011] The beneficial effects obtained from the above features are as follows: the rebar groove provides a fixed position for the upper rebar, the fixing clip is inserted into the fixing block to fix the position of the upper rebar, the upper plate and the plug-in plate. After the concrete on one side is poured and solidified, the fixing clip and the plug-in plate can be removed and reused. The upper rebar is fixed by the concrete, and pouring the other side will not affect the position of the upper rebar.

[0012] The water-stop steel plate has a zigzag arched groove in the middle. The lower end of the upper upright plate is fixed to the top of the arched groove, and the upper end of the lower upright plate is inserted and fixed inside the arched groove.

[0013] The beneficial effect obtained from the above features is that the lower plate is inserted into the lower end of the Z-shaped protrusion, making the fixation between the lower plate and the water-stop steel plate more secure.

[0014] Diagonal braces are installed between the upright plate and the water-stop steel plate for fixation.

[0015] The beneficial effect obtained from the above features is that by adding diagonal braces between the horizontal waterstop steel plate and the vertical plate, triangular support is provided for the waterstop steel plate and the vertical plate.

[0016] A pin cylinder is also provided at the corresponding position of the upper plate and the plug-in plate, and a fixing pin is inserted in the pin cylinder.

[0017] The beneficial effect obtained from the above features is that the fixing pin is inserted into the pin cylinder to fix the position of the upper plate and the plug-in plate.

[0018] The second technical solution adopted by the present invention to solve the aforementioned problem is:

[0019] The waterproofing construction method for joints using the skip-fill method includes the following steps:

[0020] Step 1: Lay the reinforcing steel bars on the cast-in-place base, and cover the reinforcing steel bars at the joints of the skip-pour method with a base of mortar of the same strength as concrete.

[0021] Its characteristic is that it further includes the following steps:

[0022] Step 2: Fix the water-stop steel plate assembly on the concrete mortar base of the same strength, with the lower end of the water-stop steel plate assembly inserted into the concrete mortar base of the same strength.

[0023] Step 3: Insert the upper layer of reinforcing bars into the reinforcing bar groove of the waterstop steel plate assembly, and use fixing clips to fix the position of the upper layer of reinforcing bars and the reinforcing bar groove;

[0024] Step 4: Pour concrete on one side of the vertical plate of the waterstop steel plate assembly. The height of the concrete should not exceed the upper surface of the vertical plate. After the concrete has solidified, pour concrete on the other side.

[0025] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art:

[0026] Through the above steps, a base of concrete mortar of the same strength as the reinforcing steel is placed on the steel reinforcement to serve as the base for fixing the water-stop steel plate. This method is both sturdy and convenient for construction. The upright plate and the water-stop steel plate have a cross-shaped structure. The upright plate supports the water-stop steel plate, and multiple steel bar grooves are cut at the upper end of the upright plate on the water-stop steel plate assembly. The upper layer of reinforcing steel is fixed in the steel bar grooves. While the water-stop steel plate stops the water, this assembly also provides support for the upper layer of reinforcing steel. During pouring, one side of the upright plate is poured first, and the other side is poured after the concrete has solidified. This effectively solves the problem of water-stopping at the joints in the skip-pour method of construction. This construction method can effectively improve the water-stopping effect, speed up the construction progress, and improve the quality of the project.

[0027] As a preferred embodiment, a further technical solution of the present invention is:

[0038] The present invention will be further described below with reference to embodiments, which are intended only to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0039] See appendix Figure 1-5 Embodiment 1 of the present invention discloses a water-stopping structure at the joint of the skip-concrete method, including: a concrete mortar base 1 of the same strength and a water-stopping steel plate assembly 2. The concrete mortar base 1 covers the building reinforcement at the joint of the skip-concrete method. The water-stopping steel plate assembly 2 is fixed on the concrete mortar base 1. The water-stopping steel plate assembly 2 includes a vertical plate and a horizontal water-stopping steel plate 22. The vertical plate and the water-stopping steel plate 22 have a cross-shaped structure. The vertical plate at the upper end of the water-stopping steel plate is provided with a plurality of horizontal steel bar grooves 241 for placing the upper layer of steel bars 3.

[0040] In this embodiment, the aforementioned water-stopping structure uses a concrete mortar base 1 of the same strength as the reinforcing steel as a base to fix the water-stopping steel plate 22, which is both sturdy and convenient for construction. The upright plate and the water-stopping steel plate 22 have a cross-shaped structure. The upright plate supports the water-stopping steel plate 22, and the upper end of the upright plate of the water-stopping steel plate 22 is provided with multiple horizontal reinforcing bar grooves 241, which fix the upper reinforcing bars 3 in the reinforcing bar grooves 241. While the water-stopping steel plate 22 stops the water, this component can also provide support for the upper reinforcing bars 3. During pouring, one side of the upright plate is poured first, and the other side is poured after the concrete has solidified, which effectively solves the problem of water-stopping at the joints when using the skip-pour method. This structure can effectively improve the water-stopping effect, speed up the construction progress, and improve the quality of the project.

[0041] In this embodiment, the upright plate includes an upper upright plate 23, a lower upright plate 21, and an insert upright plate 24. The lower upright plate 21 is fixed to the water-stop steel plate 22 and the mortar base 1 of the same strength as the concrete. The upper upright plate 23 is fixed to the upper end of the water-stop steel plate 22. The lower end of the insert upright plate 24 has a steel bar groove 241 with an inverted U-shaped structure. The insert upright plate 24 and the upper upright plate 23 near the steel bar groove 241 are provided with corresponding fixing blocks 27. Fixing clips 26 are inserted into the fixing blocks 27. The rebar groove 241 provides a position fixation function for the upper rebar 3. The fixing clip 26 is inserted into the fixing block 27 to fix the position of the upper rebar 3, the upper upright plate 23, and the plug-in upright plate 24. After the concrete on one side is poured and solidified, the fixing clip 26 and the plug-in upright plate 24 can be removed and reused. The upper rebar 3 is fixed by the solidified concrete. Pouring the other side will not affect the position of the upper rebar 3.

[0042] In this embodiment, a fixing block 27 is provided on both sides of the reinforcing bar groove 241 of the insertion plate 24, and a fixing block 27 is provided at the corresponding position on the upper plate 23. The three fixing blocks 27 are distributed in a triangle. A fixing clip 26 is inserted into the fixing block 27. The fixing clip 26 is an L-shaped steel piece. The long side of the fixing clip 26 is used to insert into the fixing block 27 to fix the position of the insertion plate 24 and the upper plate 23. The short side of the fixing clip 26 serves as a handhold for easy insertion and removal of the fixing clip 26.

The lower end of the upper upright plate 23 is fixed to the top of the arched groove 29, and the upper end of the lower upright plate 21 is inserted into and fixed in the arched groove 29. The lower end of the lower upright plate 21 is fixed to the concrete mortar base 1 of the same strength. The arched groove 29 limits the horizontal movement of the upper end of the lower upright plate 21, making the fixation between the lower upright plate 21 and the water-stop steel plate 22 more secure.

[0044] In this embodiment, the top of the zigzag arch groove 29 of the upper upright plate 23 and the water-stop steel plate 22 is fixed by welding or fixing adhesive. The upper end of the lower upright plate 21 is inserted into the arch groove 29 and fixed. The lower upright plate 21 is welded to the inner wall of the arch groove 29 or fixed by fixing adhesive, thereby increasing the firmness of the upper upright plate 23, the lower upright plate 21 and the water-stop steel plate 22.

[0045] In this embodiment, a diagonal brace 28 is provided between the vertical plate and the water-stop steel plate 22 for fixation. Specifically, corresponding slots are provided on the upper vertical plate 23 and the lower vertical plate 21 and on the water-stop steel plate 22, and the two ends of the diagonal brace 28 are inserted into the slots. The diagonal brace 28 is added between the horizontal water-stop steel plate 22 and the vertical plate to provide triangular support for the water-stop steel plate 22 and the vertical plate.

[0046] In this embodiment, a pin cylinder 30 is also provided at the corresponding position of the upper upright plate 23 and the plug-in upright plate 24, and a fixing pin 25 is inserted into the pin cylinder 30. The fixing pin 25 is inserted into the pin cylinder 30 to fix the position of the upper upright plate 23 and the plug-in upright plate 24.

[0047] In this embodiment, the fixing block 27, fixing clip 26 and diagonal bar 28 are all set on one side of the waterstop steel plate 22 and the vertical plate. After the concrete on the other side is poured and solidified, the fixing clip 26, the inserted vertical plate 24 and the diagonal bar 28 are removed in sequence and can be reused. The upper reinforcing bar 3 is fixed by the solidified concrete. Pouring the other side will not affect the position of the upper reinforcing bar 3.

[0048] See appendix Figure 1-5 Embodiment 2 of the present invention discloses a method for waterproofing joints using the skip-fill method, comprising the following steps:

[0049] Step 1: Lay the reinforcing steel bars on the cast-in-place base, and cover the reinforcing steel bars at the joints of the skip-pour method with a base of mortar of the same strength as concrete.

[0050] Step 2: Fix the water-stop steel plate assembly 2 on the concrete mortar base 1 of the same strength, and insert the lower end of the water-stop steel plate assembly 2 into the concrete mortar base 1 of the same strength.

[0051] Step 3: Insert the upper reinforcing bar 3 into the reinforcing bar groove 241 of the waterstop steel plate assembly 2, and use the fixing clip 26 to fix the position of the upper reinforcing bar 3 and the reinforcing bar groove 241;

[0052] Step 4: Pour concrete on one side of the vertical plate of the waterstop steel plate assembly 2. The height of the concrete shall not exceed the upper surface of the vertical plate. After the concrete has solidified, pour concrete on the other side.

[0053] In this embodiment, through the above steps, a concrete mortar base 1 of the same strength is covered on the reinforcing steel bars to serve as the base for fixing the water-stop steel plate assembly 2, which is both sturdy and convenient for construction. The upright plate and the water-stop steel plate 22 have a cross-shaped structure. The upright plate supports the water-stop steel plate 22, and the upright plate at the upper end of the water-stop steel plate 22 is provided with multiple horizontal reinforcing bar grooves 241, which fix the upper reinforcing bars 3 in the reinforcing bar grooves 241. While the water-stop steel plate 22 stops water, the water-stop steel plate assembly can also provide support for the upper reinforcing bars 3. During pouring, one side of the upright plate is poured first, and the other side is poured after the concrete has solidified, which effectively solves the problem of water-stopping at the joints in the skip-pour method of construction. This construction method can effectively improve the water-stopping effect, speed up the construction progress, and improve the quality of the project.

[0054] In this embodiment, the mortar base 1 with the same strength as concrete is made of mortar with the same strength as concrete. The mortar is smoothed to the required height, and then the lower plate 21 is inserted into the mortar. After the mortar solidifies, the lower plate 21 and the mortar are fixed in place.

[0055] In this embodiment, multiple waterstop steel plate components 2 are spliced ​​together according to the actual length of the joint at the skip-section method during actual construction. The connection of the waterstop steel plates 22 can be achieved by welding or other connection methods.

[0056] In this embodiment, in step two, a diagonal brace 28 is provided between the vertical plate and the waterstop steel plate 22 for fixation. Adding the diagonal brace 28 between the horizontal waterstop steel plate 22 and the vertical plate provides triangular support for the waterstop steel plate 22 and the vertical plate, enhancing the stability of the waterstop steel plate assembly.

[0057] In this embodiment, in step four, after the concrete on one side of the upright plate has solidified, the fixing clip 26 and the inserted upright plate 24 are removed in sequence before the other side of the upright plate is poured. The reinforcing bar groove 241 provides support for the upper reinforcing bar 3. After the concrete on one side is poured and solidified, the fixing clip 26 and the inserted upright plate 24 are removed and can be reused. The upper reinforcing bar 3 is fixed by the solidified concrete, so pouring the other side will not affect the position of the upper reinforcing bar 3.
