Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a self-leveling floor construction process and a construction system. BACKGROUND

[0002] With the continuous development of the construction industry, self-leveling technology emerges as the times require. Self-leveling is a kind of floor construction technology that mixes various materials with water into slurry, which is then poured on the ground to flow out and obtain high flatness. The mixed slurry is in liquid state, which is scraped by a scraper after being laid, and then quickly laid by combining with the self-leveling cement itself to realize the quickness of leveling construction.

[0003] For example, the Chinese patent with the patent number "CN 110409775 B" and the name "Construction equipment and method of inorganic mortar self-leveling floor" includes the following steps: first, use a dust collector to clean the floating dust, arrange the ash cake, control the floor height clearance, reserve space for subsequent process operation space, and then pour the heat preservation mortar. After a period of time, the surface is pressed into a certain alkali-resistant glass fiber mesh cloth, and the anti-leveling is used. After a certain number of days, a layer of water-based sealing primer is applied to maintain the moisture loss of the underlying self-leveling material. The next day, the polymer mortar is poured. When the polymer mortar can be used, the inorganic self-leveling mortar is used for surface pressing and polishing to form a one-time molding, which has good leveling effect.

[0004] The existing technology has the following disadvantages: in the existing technology, the self-leveling process is usually carried out in one step, which can achieve the effect of leveling most of the area, but when encountering a pit, the self-leveling material cannot fill the pit, and manual repair is required in the later stage, resulting in low overall efficiency.

DETAILED DESCRIPTION

[0047] In order to make the purpose, technical scheme and advantages of the embodiments of the present disclosure clearer, the technical scheme of the embodiments of the present disclosure will be described clearly and completely below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without any inventive effort fall within the scope of protection of the present disclosure.

[0048] Please refer to 1-12, a self-leveling floor construction process, comprising the following steps:

[0049] S1, base cleaning: the base impurities are cleaned by a vacuum cleaner;

[0050] S2, mortar cake: determine the leveling height, and measure the mortar cake height by using an infrared level;

[0051] S3, ground wetting: wet the ground with water, and wet the surface to have clear water;

[0052] S4, laying of primer: lay the self-leveling primer, and the laying height is 3-5mm lower than the mortar cake height; the single laying width is 1-2m;

[0053] S5, auxiliary leveling, the laid primer is assisted to level by a leveling mechanism;

[0054] S6, primer wetting: spray water on the surface of the self-leveling primer to fully wet the self-leveling primer;

[0055] S7, mesh cloth laying: after laying the primer for 2-3h, lay the mesh cloth on the surface, and the mesh cloth lap joint part is greater than 5cm;

[0056] S8, surface layer pouring: pour the mixed self-leveling surface material to the surface, and the pouring height is the same as the mortar cake level;

[0057] S9, surface layer defoaming: after pouring, use a defoaming roller to defoam back and forth, and roll flat.

[0058] Specifically, for the base cleaning: the base dust, peeled concrete surface layer, grease, cement paste or putty and other impurities that may affect the bonding strength are cleaned, and the base dust must be cleaned with a vacuum cleaner. The door and window openings and other parts are sealed in advance with cement mortar to prevent the self-leveling cement from flowing away. If the total floor leveling area is large, it needs to be divided into several parts for construction, and it is recommended to construct each room as a unit.

[0059] Then, the mortar cake is made: according to the decoration requirements, the leveling height is determined. The mortar cake height is measured by an infrared level gauge, the mortar cake spacing is 1-2m, and the mortar cake is 50cm away from the wall surface.

[0060] Ground wetting: sprinkle water on the ground to wet it, and the wetting needs to be sufficient, with a little clear water on the surface. Pave the self-leveling base material: pave the self-leveling base material, and the paving height is 3-5mm lower than the mortar cake height. The single paving width is 1-2m, which is convenient for construction operation. Then, auxiliary leveling is performed, and the paving base material is leveled by the leveling mechanism. The base material is wetted: spray water on the surface of the self-leveling base material to fully wet it. Check the wetting degree of the base material locally, and the ground is fully wet until it is in place. Laying mesh cloth: after the base material is walkable (about 2 hours), lay mesh cloth on the surface, and the overlap part of the mesh cloth cannot be lower than 5cm. The mesh cloth is fixed with a clip. Then, sprinkle water on the surface of the mesh cloth (just a little wet), and then pour the surface layer: pour the mixed self-leveling material onto the surface, and the pouring height is the same as the mortar cake level. After pouring, use a defoaming roller to defoam back and forth, and then roll it flat. Finally, maintenance: start watering after 24 hours of construction, and the maintenance time is 7 days in summer and 3 days in other seasons. When the temperature is lower than 0 degrees in winter, take anti-freezing measures, and prohibit watering. Maintenance agent needs to be used for maintenance.

[0061] The present application can lay self-leveling material at different times by two layers of self-leveling, that is, laying the base layer and the surface layer respectively, so that when the base layer has pits and grooves, the surface layer of self-leveling material can compensate. Not only can the flatness of the base layer be improved as a whole, but also the present application can further improve the flatness of the ground by setting the auxiliary leveling step after laying the base material, that is, further improving the flatness of the ground, which is convenient, time-saving and labor-saving, and has low labor intensity. No matter how thick the ground leveling is, the system is integrally formed, organically combined, does not shrink, does not sink, has high ground flatness, and the ground error is within 3mm. The system mainly uses inorganic self-leveling materials such as cement and river sand, which have the same service life as the main project.

[0063] Further, the fixed plate 1 and the fixed long rod 4 are movably connected through a universal transmission assembly, the universal transmission assembly comprises a connecting shaft ball 32 fixedly arranged on the fixed plate 1 and a connecting seat 43 fixedly arranged on the fixed long rod 4, and the connecting shaft ball 32 is movably connected in the connecting seat 43. Through the arrangement of the universal transmission assembly, the position of the fixed long rod 4 cannot be changed when the position of the fixed plate 1 is adjusted, so that the push rod 41 is always in a downward state, thereby facilitating the smoothing of the smoothing piece.

[0064] Further, the two ends of the push rod 41 are fixedly provided with support rods 42, and the support rods 42 are perpendicular to the fixed long rod 4.

[0065] The support rods 42 can be supported on the ground, and when the support rods 42 are supported, the smoothing piece on the push rod 41 is perpendicular to the ground, thereby greatly facilitating the smoothing of the smoothing piece.

[0069] Further, the lower end of the fixing plate 1 is fixedly provided with two connecting rods 31, and the fixing long rod 4 is provided with a mounting groove 401 matched with the connecting rod 31, the connecting rod 31 is provided with an elastic ball 311, and the mounting groove 401 is provided with a groove matched with the elastic ball 311.

[0070] The present application can control the orientation of the fixing long rod 4 by connecting or disconnecting the fixing plate 1 by arranging the connecting rod 31 and the matched mounting groove 401 on the fixing plate 1, which greatly optimizes the use scene and further improves the use effect of the device. Figure 1 Further, preferably, the elastic ball 311 is a magnetic ball, which can be quickly adsorbed on the magnetic block in the mounting groove 401 when the elastic ball 311 gradually approaches the mounting groove 401, that is, the installation of the fixing plate 1 and the fixing long rod 4 is facilitated, and when the two are adsorbed, the elastic ball 311 is in the mounting groove 401, at this time, the fixing long rod 4 can rotate relative to the elastic ball 311, so that the fixing long rod 4 can rotate relative to the fixing plate 1, at this time, the state is as shown in

[0072] The self-leveling material can change the direction of flow and rotate the direction of the channel by the flow pressure of the self-leveling material through the flattening piece, that is, when the flattening piece is actually used, no matter where the pushing direction is, the rotating block 5 can slide adaptively under the flow pressure when pushing, that is, the opening size of the flow channel can be kept all the time, and will not become smaller or larger due to the deviation of the flattening angle, that is, the flowability of the self-leveling material can be improved as a whole, and the flattening effect is greatly improved. Figure 11 As shown in the arrow direction shown in Figure 11 When the flow pressure moves towards the flattening piece at the position above the dashed line, the pressure can make the two rotating baffles 52 close to the flow pressure rotate along the fixed side rod 51 connected in rotation, and then under the rotation, the movable plate 53 connected can also slide under the flow pressure of the self-leveling material, and the movable plate 53 can slide away from the rotating baffle 52 of the flow pressure, and finally slide to make the rotating baffle 52 and the movable plate 53 be in a straight line, that is, as shown in Figure 11 The position, that is, the second flow channel 62 is formed between the movable plates 53 in a conical shape, and the rotating block 5 is rotatably arranged on the push rod 41, that is, under the flow pressure, the rotating block 5 can rotate to make the flow opening of the rotating block 5 be opposite to the flow direction, and the same as shown in Figure 12 When the flow pressure moves towards the flattening piece at the position below the dashed line, the direction of the rotating block 5 can be changed by the flow direction, and the third flow channel 63 can be formed in a conical shape, so that the flow opening of the rotating block 5 is opposite to the flow direction, the direction of the rotating block 5 is changed, that is, the same flow opening size is kept, the flow capacity of the self-leveling material is greatly improved, and the flattening of the ground is more convenient.
