Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of prefabricated building construction, in particular to a prefabricated residential superimposed plate strip anti-slurry structure and a construction method. BACKGROUND

[0002] In the construction of prefabricated residential buildings, the cast-in-place plate strip at the splicing position of the superimposed plate, as a core load-bearing component, is a key node for structural integrity and waterproofness. With the development of prefabricated buildings towards high-rise and large-scale, the problem of slurry bleeding in the construction of superimposed plate strips has become increasingly prominent, becoming a prominent problem affecting the quality and efficiency of construction.

[0003] During construction, after the adjacent superimposed plates are hoisted into position, the plate strip area needs to be connected by cast-in-place concrete. However, due to the deviation in the flatness of the edges of the superimposed plates, slight misalignment during installation of the components, and deformation of the formwork support system during construction, irregular gaps are easily formed at the connection between the plate strip and the superimposed plate. In traditional construction, only foam strips or sealant is used for simple treatment, and this single sealing method cannot cope with the lateral pressure and vibration impact during concrete pouring. During the pouring process, the slurry easily seeps out of the gaps, not only causing honeycomb and pitted surfaces in the plate strip area, affecting the structural bearing capacity, but also polluting the surface of the superimposed plate, increasing the workload and cost of subsequent polishing and repair.

[0004] In large-scale construction projects such as high-rise residential buildings or affordable housing, this problem is particularly prominent. The rework rate of some projects due to plate strip slurry bleeding has significantly increased, severely restricting the construction pace of "fast-flowing operation". Traditional formwork fastening methods are mostly single-sided, which can easily lead to poor adhesion of the formwork to the superimposed plate, further exacerbating the slurry bleeding problem, and lack of a mechanism to drain the seepage slurry. Once the seal fails, the slurry will accumulate inside the joint, forming a hidden quality defect. SUMMARY

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions:

[0006] A prefabricated residential superimposed plate strip anti-slurry structure, comprising:

[0007] a plate strip body arranged between adjacent superimposed plate bodies;

[0010] a reinforced sealing assembly arranged on the outside of the sealing mechanism, for providing dynamic sealing and mechanical blocking during concrete pouring;

[0011] an internal drainage assembly pre-installed inside the prefabricated cushion for collecting and discharging the grout that may permeate;

[0012] a formwork fastening assembly arranged across the two sides of the slab body for fixing the formwork and ensuring the forming quality of the slab area; and an auxiliary sealing mechanism arranged at the contact interface between the formwork and the slab body for enhancing the interface sealing.

[0013] Preferably, the sealing mechanism comprises:

[0014] a foam strip, the prefabricated cushion and the slab body are provided with a mounting groove at the connecting surface, the foam strip is arranged in the mounting groove, and the foam strip protrudes above the slab surface after being embedded in the mounting groove to absorb impact;

[0015] a water-swellable sealing glue coated on the outer side of the foam strip.

[0016] Preferably, the reinforced sealing assembly comprises:

[0017] a wave-shaped metal baffle arranged at the opening side of the mounting groove, and the other end of the wave-shaped metal baffle is fixed to the side edge of the slab for resisting the impact of concrete pouring; and a polymer cement-based sealing layer covering the joint between the prefabricated cushion and the slab body.

[0018] Preferably, the internal drainage assembly comprises:

[0019] a micro-flow guide channel formed inside the prefabricated cushion;

[0020] a liquid collection chamber in communication with the micro-flow guide channel; and a vertical exhaust pipe in communication with the liquid collection chamber.

[0021] Preferably, the formwork fastening assembly comprises:

[0022] a tensioning screw rod penetrating through the upper formwork and the lower formwork arranged at the two sides of the slab body;

[0023] a mountain-shaped clamp arranged at the two ends of the tensioning screw rod for pressing the back lath outside the upper formwork and the lower formwork.

[0024] Preferably, the auxiliary sealing mechanism comprises:

[0025] a shaped groove formed at the edge of the slab joint of the slab body;

[0026] a compressive sealing strip arranged in the shaped groove, which is located between the contact surface of the groove and the upper formwork and the lower formwork.

[0027] Preferably, the lower template is a customized aluminum mold, and the lower template has U-shaped plastic grooves deepened at corresponding positions on both sides of the joint of the composite board, with sealing sponge strips pasted inside the grooves.

[0028] Preferably, truss reinforcement bars are pre-embedded inside the adjacent composite slab bodies, and the truss reinforcement bars extend into the casting space of the slab body.

[0029] Preferably, the bottom of the vertical exhaust pipe is connected to the top of the liquid collection chamber via an L-shaped bend, and the micro-guide channel adopts a V-shaped cross-section design, with the inner wall of the guide channel coated with a nano-hydrophobic coating.

[0030] A construction method for a prefabricated residential building with a composite slab strip anti-grouting structure includes the following steps:

[0031] S1. Installation and sealing of precast pads: Place the precast pads at the designed positions between adjacent composite slab bodies, embed foam strips in the installation grooves of the precast pads and ensure that they are higher than the slab surface, apply water-swellable sealant to the outside of the foam strips, then fix the corrugated metal baffles to the side of the composite slab with rivets to cover the opening of the installation groove, and finally apply polymer-modified cement mortar to the joint between the precast pads and the composite slab body to form a sealing layer.

[0032] S2. Install templates and auxiliary sealing: Install upper and lower templates on both sides of the plate and strip body. The lower template is a customized aluminum mold that matches the shape of the plate joint, and the inner side of its U-shaped plastic groove has been pasted with sealing sponge strips. Align and press the compressible sealing strips on the edges of the upper and lower templates with the preset grooves on the composite plate body.

[0033] S3. Fastening the template system: Pass the tie rods through the lower template, the strip area, the upper template and the back ribs on both sides in sequence. Screw the wedge-shaped clips on both ends of the tie rods and tighten them to make the entire template assembly fastened as one.

[0034] S4. Pouring concrete: Pour concrete into the space of the plate strip body formed by the template and vibrate it to make it dense; the impact force of the concrete is absorbed by the foam strip, the water-swellable sealant expands when it comes into contact with water and forms a reinforced seal together with the corrugated metal baffle, and any trace amount of grout that may seep in is collected by the guide channel in the precast pad into the liquid collection chamber.

[0035] S5. Curing and Formwork Removal: After the concrete of the slab strip body reaches the specified strength, remove the tie rods, mountain-shaped clamps, back ribs and upper and lower formwork in sequence to complete the construction.

[0036] Compared with the prior art, the beneficial effects of the present invention are:

[0037] 1. Through the triple-coordinated sealing design of sealing mechanism, reinforced sealing component and auxiliary sealing mechanism, it achieves all-dimensional protection from initial sealing to dynamic blocking and interface reinforcement for irregular gaps in the joints of composite slabs and dynamic working conditions during concrete pouring. It effectively solves the pain point that traditional single sealing methods are difficult to resist the side pressure of pouring and vibration impact, completely blocks the grout leakage path, avoids honeycomb, pitting and surface contamination of composite slabs in the slab area, and greatly reduces the amount and cost of later repair work.

[0038] 2. The addition of internal drainage components and synergistic formwork fastening components ensures a tight fit between the casting formwork and the composite slab through cross-setting fixation, reducing sealing failures caused by support deformation. The internal drainage components can collect and drain any small amount of seeping grout, preventing accumulation of hidden defects in the joints. At the same time, the collaborative design of multiple components adapts to complex scenarios such as composite slab installation deviations and temperature deformation, significantly improving the forming quality and structural integrity of the slab strip, ensuring the long-term performance of prefabricated housing, adapting to the construction needs of high-rise and large-scale construction, and helping to improve construction efficiency and assembly line operation rhythm.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1

[0047] Please see Figures 1-5 The present invention provides a technical solution:

[0048] A prefabricated residential composite slab strip anti-grouting structure includes:

[0049] The strip body 1 is disposed between adjacent composite slab bodies 2. The adjacent composite slab bodies 2 are pre-embedded with truss steel bars 21, which extend into the casting space of the strip body 1.

[0050] Precast pad 3 is disposed at the connection between the strip body 1 and the composite plate body 2;

[0051] A sealing mechanism is provided at the joint between the precast pad 3 and the composite slab body 2 to achieve preliminary sealing at the joint. The sealing mechanism includes a foam strip 4. An installation groove 5 is provided on the connecting surface between the precast pad 3 and the composite slab body 2. The foam strip 4 is placed in the installation groove 5 and protrudes above the slab surface after being embedded in the installation groove 5 to absorb impact. Water-swellable sealant 6 is coated on the outside of the foam strip 4.

[0052] The reinforced sealing component, located on the outside of the sealing mechanism, provides dynamic sealing and mechanical blocking during concrete pouring. The reinforced sealing component includes a corrugated metal baffle 7 located on the opening side of the mounting groove 5, with the other end of the corrugated metal baffle 7 fixed to the side of the composite plate to resist the impact of concrete pouring; and a polymer cement-based sealing layer 8 covering the joint between the precast pad 3 and the composite plate body 2. The internal drainage component includes a micro-drainage channel 9 formed inside the precast pad 3; a liquid collection chamber 10 communicating with the micro-drainage channel 9; and a vertical exhaust pipe 11 communicating with the liquid collection chamber 10. The bottom of the vertical exhaust pipe 11 is connected to the top of the liquid collection chamber 10 by an L-shaped bend 22. The micro-drainage channel 9 adopts a V-shaped cross-section design, and the inner wall of the drainage channel is coated with a nano-hydrophobic coating.

[0053] After the adjacent composite slab body 2 is hoisted into place, ensure that the pre-embedded truss steel bars 21 inside extend accurately to the pouring space of the slab body 1. Then, install precast pads 3 at the connection between the slab body 1 and the composite slab body 2, calibrating their position and flatness to ensure they fit tightly against the side of the composite slab, providing a stable foundation for subsequent sealing and fastening. Clean the installation groove 5 on the precast pad 3, embed the foam strip 4 into the groove (ensuring it protrudes above the slab surface), and evenly apply water-swellable sealant 6 to the outside of the foam strip 4 to form a preliminary sealing barrier. This sealing mechanism is designed to absorb the impact energy during concrete pouring by utilizing the elastic structure of the foam strip 4 protruding above the slab surface. The water-swellable sealant 6 expands upon contact with the grout moisture, filling the tiny gaps between the foam strip 4 and the installation groove 5, completing the first layer of protection. Next, the corrugated metal baffle 7 is fixed to the side of the composite slab and covers the opening side of the mounting groove 5. Then, a polymer cement-based sealing layer 8 is applied to the joint between the precast pad 3 and the composite slab body 2, covering the sealing mechanism and the outside of the corrugated metal baffle 7, forming a reinforced sealing component. The corrugated metal baffle 7 directly resists the lateral pressure of concrete and the impact of vibration through a rigid structure, forming a mechanical barrier. The polymer cement-based sealing layer 8 provides rigid sealing protection, forming a "flexible + rigid" dual seal with the sealing mechanism. The two work together. The sealing mechanism undertakes the initial buffering and flexible sealing, relieving the pressure of concrete impact on the subsequent structure. The corrugated metal baffle 7 provides rigid support for the sealing mechanism, preventing the foam strip 4 from being over-compressed and failing. The polymer cement-based sealing layer 8 eliminates the joint gaps, achieving the synergistic protection of "buffering-blocking-sealing", which greatly improves the reliability of the seal.

[0054] An internal drainage component, which is pre-placed inside the precast pad 3, is used to collect and drain any grout that may seep in.

[0055] The template fastening assembly spans both sides of the strip body 1 and is used to fix the casting template and ensure the forming quality of the strip area. The template fastening assembly includes tie rods 12, which pass through the upper template 13 and the lower template 14 set on both sides of the strip body 1; and mountain-shaped clips 15 set at both ends of the tie rods 12 to press the back ribs 16 on the outside of the upper template 13 and the lower template 14. The lower template 14 is a customized aluminum mold, and the lower template 14 has U-shaped plastic grooves 19 deepened at the corresponding positions on both sides of the joint of the composite plate. Sealing sponge strips 20 are pasted on the inner side of the grooves 19.

[0056] After the sealing structure is installed, upper template 13 and lower template 14 (lower template 14 is a custom aluminum mold with a built-in U-shaped plastic groove 19) are laid on both sides of the strip body 1. Sealing sponge strips 20 are pasted inside the grooves 19. Then, tie rods 12 are passed through the upper and lower templates 14, and U-shaped clips 15 are installed at both ends of the tie rods to press the back ribs 16 on the outside of the templates to achieve cross-fixing. At the same time, compression sealing strips 18 are embedded in the shaping grooves 17 at the edges of the strip body 1 to ensure that they fit tightly against the contact surface between the groove and the template. The vertical exhaust pipes 11 are checked for unobstructed flow, and the overall assembly is completed. In this process, the template fastening components and the auxiliary sealing mechanism work together efficiently: the tie rod 12, the mountain-shaped clip 15, and the back rib 16 generate a cross-fixing force, which makes the U-shaped plastic groove 19 of the lower template 14 fit tightly with the composite plate. The sealing sponge strip 20 in the groove 19 further enhances the interface sealing and prevents the sealing mechanism from being squeezed and damaged due to template deformation. The shaping groove 17 provides positioning support for the compressible sealing strip 18 and prevents it from shifting. The sealing strip is fully deformed under the action of the clamping force, filling the interface gap between the template and the composite plate. Together with the U-shaped plastic groove 19 and the sealing sponge strip 20, it forms an interface sealing synergy of "groove positioning + sealing strip sealing + groove 19 fitting", which completely blocks the grouting path of the contact surface between the template and the composite plate. This synergistic principle of template fastening and interface sealing ensures the structural stability from both the fixing and sealing dimensions.

[0057] When pouring concrete into the casting space of the slab body 1, it is necessary to observe the venting of the vertical vent pipe 11. At this time, the internal drainage component plays a "bottom-line protection" role: if a small amount of grout breaks through the multiple seals and seeps in, the V-shaped cross-section micro-guiding channel 9 inside the precast pad block 3 (with a nano-hydrophobic coating on the inner wall to reduce grout adhesion) will guide the grout to the collection chamber 10. After temporary storage in the collection chamber 10, the grout is discharged through the vertical vent pipe 11 connected by the L-shaped bend 22 or overflows with the gas, preventing the grout from accumulating inside the joint. The synergy between the multiple sealing system and the internal drainage component not only minimizes grout seepage through the triple structure of "sealing mechanism + reinforced sealing component + auxiliary sealing mechanism", but also effectively treats small leaks through the drainage component, reducing the extreme sealing pressure of the sealing system and preventing the leakage grout from forming hidden defects, thus achieving comprehensive and reliable protection. After the concrete is formed, the formwork and fastening components are removed, and the vertical vent pipe 11 is sealed to complete the entire construction process.

[0058] An auxiliary sealing mechanism is provided at the contact interface between the casting template and the composite plate body 2 to enhance the interface sealing. The auxiliary sealing mechanism includes: a shaping groove 17 formed on the edge of the plate joint of the plate body 1; and a compressible sealing strip 18 provided in the shaping groove 17, which is located between the groove and the contact surfaces of the upper template 13 and the lower template 14.

[0059] In the entire system, the synergistic design of rigid barriers (wave-shaped metal baffles 7) and flexible buffers (foam strips 4), rigid seals (polymer cement-based sealing layer 8) and expansion seals (water-swellable waterproof sealant 6) enables dynamic adaptation to complex working conditions such as installation deviations and temperature deformation of composite slabs during construction, exceeding the expectation that traditional sealing structures can only cope with a single working condition. Ultimately, through the triple sealing synergy of "sealing mechanism + reinforced sealing component + auxiliary sealing mechanism", a full-dimensional, dead-angle-free seal from the inside of the joint to the template interface is achieved. This solves the problem that traditional single sealing methods are unable to withstand the impact and lateral pressure of pouring and are prone to leakage through gaps. It completely avoids honeycombing, pitting, and surface contamination of the composite slab area and reduces the amount of subsequent repair work. The internal drainage component of "V-shaped guide channel + liquid collection chamber 10 + vertical exhaust pipe 11" solves the problem of traditional technology lacking a leakage catch-up mechanism and grout accumulation forming hidden defects, ensuring the integrity and durability of the slab structure. The cross-set fastening structure of customized aluminum mold and tie rod 12, together with the auxiliary sealing component, solves the problem of traditional single-sided template fixing not being tight and aggravating grout bleeding, improving the slab forming quality. It is fully adapted to the construction needs of high-rise and large-scale prefabricated housing and ensures the long-term performance of the building.

The lower template 14 is a customized aluminum mold that matches the shape of the plate seam, and the inner side of its U-shaped plastic groove 19 has been pasted with sealing sponge strip 20. Align and press the compressible sealing strips 18 on the edges of the upper template 13 and lower template 14 with the preset grooves on the composite plate body 2.
