When in use, when a tire passes by, the first template 100 has a larger contact area with the tire, and the edge protection effect is better. The anchoring structure can effectively prevent the settlement of the splitting device, and the combination with the concrete floor is tighter, the flatness of the floor is better, and the noise when the vehicle passes by can be greatly reduced;

[0025] The support member 200 is used to connect the first template 100 structure on one hand, improve the anchoring performance with the concrete floor, and at the same time can bear the force transmission member, used for the transmission of longitudinal loads between the concrete floors on both sides; the support member 200 includes a horizontal portion 210, and the horizontal portion 210 is fixedly connected to the first template 100; the end of the horizontal portion 210 extends downward to form a vertical portion 220; the vertical portion 220 extends from one end of the horizontal portion 210 to form a bending portion 230; the horizontal portion 210 is mainly used to achieve a fixed connection with the first template 100 and provide support; the support member 200 is symmetrically arranged with two, such as Figure 1 As shown, the two support members 200 are usually connected by welding; in one embodiment, they can also be connected by screws; in one embodiment, the two first templates 100 can be connected by easy-break bolts, specifically easy-break nylon bolts; the support member 200 is also used to raise the height of the seam dividing device so that it can adapt to the concrete floor of corresponding thickness;

[0026] The anchoring structure may be provided in multiple numbers and in multiple types. In one embodiment, the anchoring structure includes a plurality of first anchoring portions 110 provided on the side of the first template 100 and connecting the first template 100 and the support member 200 at the same time. The first anchoring portion 110 may be Figure 1 The "匚" type in the figure can also be a "C" type. The first anchoring part 110 can enhance the anchoring performance with the concrete floor and effectively transfer the lateral and vertical loads. The first anchoring part 110 can also improve the connection strength between the first template 100 and the support member 200, and solve the problems of hollowing, settlement, and warping of the concrete floor. The first template 100 can also meet the needs of concrete shrinkage and avoid cracking.

[0027] In another embodiment, the anchoring structure includes a plurality of second anchoring portions 120 that are spaced apart on the first template 100 and extend in the horizontal direction; an anchoring strengthening portion 121 is formed at one end of the second anchoring portion 120 away from the first template 100; the second anchoring portion 120 may be cylindrical, and the anchoring strengthening portion 121 is a cylindrical structure with a diameter larger than that of the second anchoring portion 120; in another embodiment, the second anchoring portion 120 is provided on the vertical portion 220; the first anchoring portion 110 and the second anchoring portion 120 may exist simultaneously;

[0028] In another embodiment, the anchoring structure includes a plurality of third anchoring portions 130 that are spaced apart on the support member 200 and extend in the horizontal direction; the third anchoring portion 130 has a longer length in the length direction of the joint dividing device, has a larger contact area compared to the first anchoring portion 110 and the second anchoring portion 120, has a better effect in the transmission of vertical loads, and has a better bonding strength with the concrete ground; the first anchoring portion 110, the second anchoring portion 120, and the third anchoring portion 130 preferably exist simultaneously, can promote each other, ensure a better bonding effect with the concrete ground, and have improvements in both load transmission and the strengthening of the structure at the joint dividing position;

[0029] During construction, at the settlement joint position of the building bearing ground, it is easy to have construction difficulties such as settlement of the ground, resulting in floor cracking and hollowing, such as Figure 3As shown in the figure, the utility model solves this problem through a first-floor bearing ground settlement joint structure. The joint structure includes a settlement joint 401 and the first-floor bearing ground 400 on both sides of the settlement joint 401; an extruded polystyrene board medium 300 is provided at the top of the settlement joint 401; a joint device is provided at the top of the extruded polystyrene board medium 300; a crushed stone cushion layer 410, a first interface agent layer 420, a fine sand layer 430, a second interface agent layer 440, and a cement layer are provided on the top of the first-floor bearing ground 400 from bottom to top; the extruded polystyrene board medium 300 is fixed by the crushed stone cushion layers 410 on both sides, serving as a support structure for the joint device and providing buffering; by arranging the extruded polystyrene board medium 300 at the settlement joint 401, the structure at the position where settlement is likely to occur originally is blocked. The thickness of the extruded polystyrene board medium 300 is usually 4-5 cm. The widths of the first anchoring part 110, the second anchoring part 120, and the third anchoring part 130 are all greater than the thickness of the extruded polystyrene board medium 300. There is a cement layer to support under the anchoring structure. When the joint device bears the load, the anchoring structure can better transfer the load to the cement layer. The crushed stone cushion layer 410 under the cement layer is arranged on both sides of the extruded polystyrene board medium 300. The hardness and strength of the extruded polystyrene board medium 300 are less than those of the crushed stone cushion layer 410. When bearing the load, the crushed stone cushion layer 410 can squeeze the extruded polystyrene board medium 300 towards the middle, thus ensuring the stable connection of the extruded polystyrene board medium 300 at the settlement joint 401 and at the same time preventing the crushed stones in the crushed stone cushion layer 410 from falling into the settlement joint 401, which may affect the structural stability at the joint as the settlement joint 401 sinks; the extruded polystyrene board medium 300 is preferably a hollow structure, enabling it to have a certain deformation ability; the joint device mainly realizes the anchoring and force transmission with the cement layer through the anchoring structure, and does not rely entirely on the extruded polystyrene board medium 300 for support;

[0030] The crushed stone cushion layer 410 includes three layers, and the cement layer includes a high-strength aluminous cement layer 450, a first fine aggregate high-strength aluminous cement layer 460, a second fine aggregate high-strength aluminous cement layer 470, and a wire mesh high-strength aluminous cement layer 480 from bottom to top.

[0031] Application Case: At the first-floor bearing floor of the first-phase floor renovation project of Yonghui Logistics Warehouse in Nanyu, Fuzhou, the floor at the settlement joint position of the bearing floor cracked and became hollow and could not be repaired. At the settlement joint position of the first-floor bearing floor of Warehouse No. 1 in Yonghui Logistics Warehouse in Nanyu, Fuzhou, the traditional angle steel and steel plate were connected to the concrete. After years of use, settlement cracks, hollows occurred, affecting the safety of forklifts and personnel. Also, due to high load and high usage frequency, the original bearing floor at the settlement joint position was damaged, chipped, cracked, and hollow. If according to the traditional plan, the damaged emery floor needs to be milled to the foundation, cleaned, then concrete is poured and emery is sprinkled, and it also needs to be cured for 20 days. The prefabricated angle steel and steel plate are connected to the concrete. However, the storage unit of the user could not spare time due to work, and at the same time was worried that using the traditional connection method of angle steel and steel plate to the concrete would still only address the symptoms rather than the root cause. The self-leveling cement repair and renovation plan was adopted to solve the problems of fast, efficient, and cost-effective for the user unit. As it was put into use, it was found that the strength of the self-leveling cement met the requirements. The self-leveling cement with a low shrinkage rate had fine cracks after long-term high-frequency use, and there might be expansion and extension of the fine cracks during long-term high-frequency and high-strength use, thus affecting the development of logistics warehouse work.

[0032] Based on the original self-leveling cement, the applicant incorporated polyethylene fibers to improve the toughness of the self-leveling cement, enhance the crack resistance performance, and ultimately increase the flexural strength. This enables the user unit to reduce the occurrence of fine cracks due to high-strength and high-frequency use, ensuring that the floor renovation meets the usage requirements. And a joint dividing device and the 400 settlement structure of the first-floor bearing ground are used to transform the original floor, greatly improving the various functional requirements of the logistics warehouse for the floor. When the user unit's usage situation was visited three years later. At the settlement joint position of the first-floor bearing floor, the prefabricated joint dividing device of the present utility model was used. Through high-intensity, high-frequency use and the operation at the settlement position, no cracking, hollowness occurred at the settlement joint position of the first-floor bearing floor due to high load, high frequency, and settlement problems. The fine cracks were effectively controlled, greatly improving the overall safety, aesthetics, practicality, toughness, crack resistance performance, and thus increasing the flexural strength.

[0033] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in the relevant technical fields, shall be equally included in the patent protection scope of the present utility model.
