[0021] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the schemes of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the description are only some of the embodiments of the present application, not all the embodiments.

[0023] In the construction process of large-area and high-precision one-time forming floor, generally, the area is divided, and then the concrete is poured according to the area, and the construction joint is formed between the first-poured concrete area and the later-poured concrete area.

[0024] In the traditional processing mode, a profile steel is generally used as a floor joint material, but in the long-term use process, when the floor joint changes in size due to thermal expansion and cold contraction, the profile steel cannot produce corresponding deformation, which may cause the laid floor to be uneven and exist safety hazards.

[0025] In order to solve the above technical problems, please refer to Figure 1 The present application provides a floor joint system 100, which can include a first floor 110, a second floor 120, an underlayer filler 130, a connecting member and a surface layer filler 143.

[0026] Among them, it can be understood that the first floor 110 is an area formed by pouring concrete for the first time, the second floor 120 is an area formed by pouring concrete for the second time, and the first floor 110 and the second floor 120 are arranged in a first direction. Taking the partition pouring of an industrial plant concrete floor as an example, the first direction is the direction of the first floor 110 towards the second floor 120.

[0027] The floor joint is defined between the first floor 110 and the second floor 120. The floor joint can include an upper joint section and a lower joint section. The upper joint section is located on the upper side of the lower joint section. The width of the upper joint section is greater than the width of the lower joint section. The width of the upper joint section refers to the size of the upper joint section in the first direction, and the width of the lower joint section refers to the size of the lower joint section in the first direction.

[0028] The lower filler 130 is filled in the lower joint section. The lower filler 130 can be a filler with a cushioning effect. Specifically, the lower filler 130 can be an expanded polyethylene material. The expanded polyethylene material has a lightweight cushioning performance and can effectively absorb impact force.

[0029] In this way, when the first floor 110 and the second floor 120 deform due to environmental factors or long-term use, the width of the lower joint section will change. Since the lower filler 130 is an expanded polyethylene material, even if the width of the lower joint section becomes smaller or larger, it can always be filled in the lower joint section to provide a cushion between the first floor 110 and the second floor 120, avoiding damage caused by hard collision between the first floor 110 and the second floor 120.

[0030] The connecting piece is filled in the upper joint section. The connecting piece includes a first surface piece 141 and a second surface piece 142 spaced apart in the first direction. The first surface piece 141 and the second surface piece 142 define a surface joint therebetween.

[0031] The surface filler 143 is filled in the surface joint. The surface filler 143 can be a silicone material. The silicone material is a material with elasticity. By setting the surface filler 143 to be a silicone material, on the one hand, the first surface piece 141 and the second surface piece 142 can be connected. On the other hand, the first surface piece 141 and the second surface piece 142 can be provided with elastic cushioning to avoid damage caused by hard collision of the first surface piece 141 and the second surface piece 142.

[0032] The surface joint is staggered with the lower joint section in the vertical direction. It can be understood that when the concrete hardens and shrinks or expands, the surface joint is staggered with the lower joint section. The stress can be dispersed to different planes to avoid stress superposition in the same vertical plane, reduce the risk of penetrating cracks, and thus prolong the service life of the floor joint system 100.

[0033] Furthermore, the surface joint is in a wave shape. Specifically, the cross section of the side surface of the first surface piece 141 facing the second surface piece 142 is formed in a wave shape. The cross section of the side surface of the second surface piece 142 facing the first surface piece 141 is formed in a wave shape and corresponds to the side surface of the first surface piece 141 facing the second surface piece 142 to form the surface joint.

[0034] It can be understood that, compared with the straight joint, the wavy surface joint has a curved profile, which makes the load transmission path diffuse at multiple angles, significantly reducing the stress peak of the surface joint. The wavy structure forms a natural mortise and tenon effect, effectively resisting the horizontal shear force of the first floor 110 and the second floor 120, thereby improving the service life of the floor joint system 100.

[0035] In this way, by using the floor joint system 100 provided in the present application, when the floor changes due to thermal expansion and contraction, the unevenness of the floor can be reduced, the occurrence of safety hazards can be reduced, and the service life of the floor joint system 100 can be improved.

[0036] The first surface member 141 and the second surface member 142 are both made of glass fiber composite carbon fiber polymer material. It should be noted that the first surface member 141 and the second surface member 142 made of glass fiber composite carbon fiber polymer material have the characteristics of high stiffness and tensile strength, which can reduce the expansion of cracks and reduce the risk of brittle fracture.

[0037] In some embodiments of the present application, the floor joint system 100 can further include a flat member 150, and the floor joint further includes a first joint section located between the upper joint section and the lower joint section and connected to the upper joint section, and the flat member 150 is filled in the first joint section.

[0038] The flat member 150 can be made of epoxy adhesive mortar material, which can realize the connection between different materials and provide a flat mounting surface for the connecting member, ensuring the stability of the installation of the connecting member.

[0039] In some embodiments of the present application, the floor joint system 100 can further include an adhesive member 160, and the floor joint further includes a second joint section connected between the first joint section and the upper joint section, and the adhesive member 160 is filled in the second joint section. The adhesive member 160 can also be a separation material, which realizes the adhesion of the connecting member and the flat member 150 by setting the adhesive member 160.

[0040] The present application also provides a construction method of the floor joint system 100. Specifically, the method can include:

[0041] Determine the interval position between the first floor 110 and the second floor 120, and process the upper joint section and the lower joint section.

[0042] The lower joint section can be the original joint between the adjacent existing floor, and only the upper joint section needs to be processed. Specifically, according to the actual requirements, the position and size of the upper joint section are accurately measured and marked on the concrete surface, and the size of the connecting piece is marked with a line. The connecting piece is reserved by 5mm upward, downward, left and right to reduce the influence of assembly error.

[0043] In order to realize the overlap of the surface joint and the lower joint section in the up-down direction, taking the example that the orthographic projection of the lower joint section on the upper joint section is located in the middle region of the upper joint section, the width of the first surface piece 141 is set to be small, which is 90mm, and the width of the second surface piece 142 is set to be large, which is 180mm. The total width of the upper joint section is 270mm.

[0044] In the process of processing the upper joint section, in order to ensure that the connecting piece has sufficient installation position, the depth of the upper joint section is greater than or equal to 20mm. A concrete cutting device such as a diamond saw blade cutting machine is used to cut along the marked cutting groove position. During the cutting process, the cutting speed and depth should be controlled to avoid cutting too deep or too shallow, and attention should be paid to prevent the heat generated during cutting from damaging the concrete structure. Manual hand-held wind pick or electric pick is used for chiseling. When operating, the construction personnel should pay attention to safety, wear protective equipment, and chisel the concrete gradually from the edge to the middle to avoid excessive force causing damage to the groove wall.

[0045] Clean the upper joint section and polish after repair. Use a dust collector to completely remove dust, debris and other impurities in the upper joint section. After cleaning, the epoxy repair mortar base is repaired, and the diamond grinder is used to grind the bottom of the cutting groove. After polishing, use a dust collector to clean the dust on the base to prevent dust from affecting the bonding effect, and then proceed to the next step.

[0046] The lower layer filling piece 130 is filled in the lower joint section.

[0047] Among them, the lower layer filling piece 130 is installed, and the lower layer filling piece 130 is prepared according to the width of the lower joint section. The width of the repaired lower joint section is measured with a ruler, and the lower layer filling piece 130 is cut into the appropriate length and width with scissors or wallpaper knife according to the measurement result. When cutting, pay attention to the size accuracy to ensure that the foam strip can be tightly installed in the cutting groove. First, clean the lower joint section to ensure that there is no debris and dust. Then evenly apply a thin layer of adhesive to the bottom and both sides of the lower joint section with a brush. Gently place the cut lower layer filling piece 130 into the cutting groove, and gently press it with a tool to make it tightly fit the bottom and both sides of the lower joint section. If the foam strip is too long or too wide, it can be properly trimmed to make it flush with the edge of the cutting groove.

[0048] The flat piece 150 is filled in the first joint section, so that the surface of the flat piece 150 is flat.

[0049] The adhesive 160 is filled in the second joint section. The adhesive 160 can be formed by curing the adhesive, and the adhesive is properly adjusted by a spatula or a special tool to make the thickness of the adhesive layer uniform. According to the thickness requirement of the connecting piece, the upper joint section is adjusted to a depth of 15 mm using a spatula. The adhesive is first applied to the edges of the cut groove, and then the remaining material concentrated at one end is spread using an adjustable spatula.

[0050] The first surface layer 141 and the second surface layer 142 are installed on the upper joint section through the adhesive 160.

[0051] The first surface layer 141 and the second surface layer 142 are spread on the adhesive 160. It is confirmed that the adhesive is evenly applied, and there are no bubbles or hollows under the installed first surface layer 141 and second surface layer 142. The first surface layer 141 and the second surface layer 142 are pressed to ensure that they are completely bonded to the adhesive 160, and the installation position of the profile is avoided to be adjusted by using a hammer.

[0052] The surface filling piece 143 is filled in the surface joint.

[0053] Further, the construction method can further include:

[0054] After the adhesive 160 is cured, the surface of the first surface layer 141 and the second surface layer 142 is polished until the first surface layer 141 and the second surface layer 142 are flush with the first floor 110 and the second floor 120.

[0055] The first surface layer 141 and the second surface layer 142 are installed for 24 hours, and then a curing agent can be applied to the surface of the first surface layer 141 and the second surface layer 142. After the curing agent is applied, the curing agent is cured in a specified temperature environment. Generally, the temperature should be controlled between 15-35°C. Avoid curing in a high temperature and high humidity environment to avoid affecting the curing effect. The curing agent not only increases the strength of the first surface layer 141 and the second surface layer 142, but also makes the surface easy to clean.

[0056] The construction method provided by the present application has the effect of good quietness, the profile and the joint between the profile and the ground are smooth and have no height difference, which provides a quiet and comfortable working environment for the user, improves the overall integrity and aesthetics of the ground, and also protects the health of the workers.
