Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a construction method for connecting joints of floor blocks made of different materials. Background Art

[0002] The treatment of joints between floor tiles of different materials is a common detail in renovation projects. Reasonable treatment methods can not only ensure the aesthetics of the space, but also avoid bulging and cracking problems caused by material differences. Currently, the joints between different floor tiles in China mostly adopt the construction method of direct docking and covering strips, or the construction process of reserved expansion joints combined with caulking treatment. The former is prone to expansion and contraction when the temperature of the paving environment changes due to the temperature sensitivity of the material. The lack of expansion joints causes bulging or cracking at the joints, affecting the use function and visual perception. Although the latter sets expansion joints and alleviates the joint problems caused by temperature deformation to a certain extent, the caulking agent is prone to cracking or falling off after long-term use, and the original caulking material needs to be removed and refilled, which has poor durability. Summary of the Invention

[0003] In view of this, in order to solve the technical problem of bulging and cracking caused by the lack of seams at the joints of floor blocks of different materials, the present invention provides a construction method for connecting floor blocks of different materials. By filling a full-length liquid sac with a non-Newtonian liquid, its creep property under static conditions allows it to support the upper block while filling the full-length groove under the block due to the gravity of the block itself, thereby connecting the blocks on both sides. In the case of sudden pressure, the stress bearing capacity of the non-Newtonian liquid under sudden load ensures that the surface layer of the block will not be crushed. At the same time, since there is a gap between the full-length liquid sac and the full-length groove in static conditions, and a certain gap is also left at the joints of the plates. When the plate is deformed by temperature changes, it squeezes or stretches the liquid sac, which can release this part of the stress and will not cause cracking or hollowing.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] The construction method for connecting the joints of floor tiles of different materials includes the following steps:

[0006] Step (1): Prepare non-bonding connection measures

[0007] A full-length liquid sac filled with non-Newtonian liquid is prefabricated, and a full-length groove is opened on the back of the floor block;

[0008] Step (2): Laying the liquid capsule

[0009] After the ground base is cleaned and accepted, a full-length liquid bag filled with non-Newtonian liquid is laid along the longitudinal direction of the joint; step (3), construction of the lower bearing layer

[0010] Construct the supporting layer on both sides of the full-length liquid bag according to the block material type;

[0011] Step (4): Laying the floor tiles

[0012] After the construction of the lower bearing layer is completed, lay the blocks on both sides and leave gaps at the joints;

[0013] Step (5): Apply adhesive and paste the strips

[0014] Apply adhesive longitudinally along the joint on the non-wood block side and stick the layering strip.

[0015] Preferably, in step (1), the depth of the through-length groove is 1 / 3 of the thickness of the plate, and the width is 1 cm.

[0016] Preferably, in step (3), the block types include wooden blocks and non-wooden blocks, bonding mortar is laid on the non-wooden block side, and wooden keels are laid on the wooden block side.

[0017] Preferably, in step (3), the upper elevation of the lower supporting layer is lower than the upper elevation of the normal liquid bag, ensuring that the full-length liquid bag fills the full-length groove after the block is laid, and a gap is reserved between the upper surface of the full-length liquid bag and the top of the full-length groove after filling.

[0018] Preferably, in step (4), the gap width is 5-10 mm.

[0019] Preferably, the through-length liquid bladder is made of a soft material that is wear-resistant and high-strength.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) Non-Newtonian liquid sac: intelligent balance of dynamic and static performance

[0022] Specific structure: A full-length liquid capsule made of wear-resistant, high-strength soft material, filled with non-Newtonian liquid (the filling amount is determined by the upper load test to determine the equilibrium deformation pressure).

[0023] Advantages:

[0024] Static deformation adaptation: Non-Newtonian liquid has creep properties under static conditions. It can fill the full-length groove on the back of the ground block under the action of the block's own weight (the groove depth is 1 / 3 of the plate thickness and the width is 1 cm), realizing flexible connection of the blocks on both sides; at the same time, a gap is reserved between the upper surface of the liquid sac and the top of the groove to provide a buffer space for the expansion and contraction of the block caused by temperature changes, avoiding the cracking and hollowing problem caused by "unbuffered stress concentration" in traditional direct docking construction.

[0025] Dynamic load-bearing reinforcement: When subjected to sudden loads (such as people walking or heavy objects rolling over), the non-Newtonian liquid hardens instantly, providing stress-bearing capacity to prevent the block surface from collapsing, solving the defect of traditional sealants that they are "statically rigid but dynamically fragile".

[0026] (2) Full-length groove and reserved gap: multi-dimensional stress relief design

[0027] Specific structure: The floor blocks with full-length grooves are prefabricated in the factory, and a 5-10mm gap is reserved at the joints of the blocks when they are laid on site.

[0028] Advantages:

[0029] Groove bite effect: The groove on the back of the block forms an "embedded" connection with the liquid sac, which not only ensures the flatness of the surface layer, but also disperses local deformation stress through the fluidity of the liquid sac, avoiding seam cracking caused by stretching / extrusion in a single direction.

[0030] Multi-dimensional gap buffering: The longitudinal full-length groove and the 5-10mm horizontal joint gap form a three-dimensional stress release system. When blocks of different materials shrink / expand due to temperature and humidity differences, the liquid capsule can fill or retreat the gap space through deformation, completely solving the problem of the traditional "leaving gap + filling" process where the sealant cannot adapt to deformation after curing.

[0031] (3) Single-sided adhesive stripping: double guarantee of durability and adaptability

[0032] Specific structure: Only apply adhesive along the longitudinal joint on one side of the non-wood block and stick the pressure strip.

[0033] Advantages:

[0034] One-way deformation compatibility: The one-sided adhesive design allows the layering strips to not be torn when the wood blocks produce longitudinal creep due to changes in moisture content (traditional double-sided fixed layering strips are prone to breakage due to differential deformation on both sides). At the same time, the layering strips cover the joints to prevent dust, water and other environmental factors from corroding the liquid capsule, solving the durability problem of traditional caulking agents that "are prone to aging and falling off when directly exposed".

[0035] Simplified maintenance process: The layering strips can be removed and replaced. If the liquid capsule needs to be maintained later, there is no need to remove the block materials on a large scale, and the operation can be carried out by simply removing the layering strips, which reduces maintenance costs.

[0036] (4) Prefabrication and modular construction: Improved efficiency and precision

[0037] Specific structure: Liquid capsules are prefabricated in the factory (customized according to the length of the joints), and the grooves on the back of the blocks are grooved in the factory.

[0038] Advantages:

[0039] Simplified on-site construction: avoiding the complex processes of traditional on-site cutting and caulking, steps such as sac laying and underlying layer construction (such as tile-side bonding mortar and wooden keels on the wooden flooring side) can be standardized, improving construction efficiency by more than 30%.

[0040] Enhanced quality controllability: Factory prefabrication ensures the sac size accuracy (such as length and liquid filling volume) and groove consistency (depth 1 / 3 plate thickness, width 1cm), avoiding problems such as uneven seams and sac damage caused by on-site manual operation errors.

[0041] (5) Full life cycle cost optimization

[0042] Comprehensive structural function: wear-resistant high-strength material of liquid capsule + long-term stability of non-Newtonian liquid + layering protection system.

[0043] Advantages:

[0044] Reduced post-maintenance: Compared with the 3-5-year replacement cycle of traditional caulking agents, the present invention can extend the life of the joints to more than 10 years through the coordinated protection of the liquid capsule and the pressure strip, reducing the material and labor costs of multiple repairs.

[0045] Adaptable to multiple application scenarios: Whether it is a combination of different materials such as ceramic tiles and wooden floors, stone and plastic floors, the limitations of "poor material adaptability" of traditional technology can be solved by adjusting the liquid sac specifications (length, liquid pressure) and the layering material (metal, PVC, etc.).

[0058] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0059] like Figure 1-11 As shown, the present invention provides a construction method for connecting the joints of floor blocks 2 of different materials, comprising the following steps:

[0060] Step (1): Prepare non-bonding connection measures (set up non-bonding connection measures at the joints of different material blocks)

[0061] A prefabricated, full-length liquid sac (1) filled with non-Newtonian fluid is prefabricated to a length corresponding to the longitudinal length of the joint. (Before the sac is filled with fluid, the final equilibrium deformation pressure is determined based on an upper load test. The pressure at this point is recorded, and the sac is then filled with non-Newtonian fluid in batches based on the experimental data.) The floor tiles (2) with full-length grooves (21) are pre-grooved on the back of the panels at the factory. The full-length grooves (21) are preferably 1 / 3 the panel thickness deep and 1 cm wide.

[0062] Step (2): Laying the liquid capsule

[0063] After the ground base layer 6 is cleaned and passed the quality inspection, a normal liquid bag is laid longitudinally at the joint. The liquid bag is usually made of a soft material with wear resistance and high strength (such as rubber, polyurethane, nylon, etc.) to ensure that it has deformation while ensuring wear resistance during use.

[0064] Step (3): Construction of the lower bearing layer 3

[0065] The lower bearing layer 3 is constructed on both sides of the full-length liquid capsule 1 according to the block material type. Specifically, it can be:

[0066] After the full-length liquid sac 1 is laid, the lower supporting layer 3 of the block is constructed on both sides of the full-length liquid sac 1 according to the different construction techniques of the ground blocks 2 (the block types include wooden blocks 22 and non-wooden blocks 23, bonding mortar is laid on the side of the non-wooden blocks 23, and wooden keels are laid on the side of the wooden blocks 22) (taking floor tiles and wooden floors as an example, bonding mortar and wooden keels are laid on both sides of the full-length liquid sac 1 respectively). The upper elevation of the lower supporting layer 3 is slightly lower than the upper elevation of the liquid sac to ensure that after the upper board is laid, the full-length liquid sac 1 can be filled into the full-length groove 21 of the block under the action of gravity (after the full-length liquid sac 1 fills the full-length groove 21, there is a certain gap between the upper surface of the full-length liquid sac 1 and the upper surface of the full-length groove 21).

[0067] Step (4): laying ground blocks 2

[0068] After the construction of the lower bearing layer 3 is completed, the blocks on both sides are laid, and gaps are reserved at the joints. During construction, a gap of 5-10mm is reserved at the joints of the boards.

[0069] Step (5): Apply adhesive 4 and paste pressure strip 5

[0070] After the board is laid, an adhesive 4 is applied longitudinally along the joint of the non-wood block 23 on one side, and a pressure strip 5 is pasted.

[0071] In the above-mentioned method for connecting the joints of floor tiles 2 made of different materials provided by the present invention, the full-length liquid capsule 1 filled with non-Newtonian liquid has the following advantages:

[0072] Static support and deformation adaptation: Under static conditions, the creep characteristics of the block fill the full-length groove 21, connecting the blocks on both sides and releasing temperature deformation stress to avoid cracking and hollowing.

[0073] Dynamic bearing: When subjected to sudden loads (such as people walking), the liquid stress bearing capacity prevents the block surface from collapsing.

[0074] The full-length groove 21 and the reserved gap: the groove provides a space for the liquid capsule, and the reserved gap further buffers the extrusion or tensile stress caused by temperature deformation.

[0075] One-sided pasting of the layering strip 5: This prevents the layering strip 5 from being torn during creep of the block material, while protecting the liquid capsule from environmental erosion and improving durability.

[0076] The above description is merely a preferred embodiment of the present invention. However, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical scope disclosed in the present invention and who makes equivalent substitutions or modifications based on the technical solution of the present invention and its improved concepts shall be covered by the scope of protection of the present invention.
