Description

Technical Field

[0001] This utility model relates to a multi-layer composite terrazzo floor. Background Technology

[0002] Terrazzo flooring is a decorative flooring material made from a mixture of cement, resin, or epoxy binders and aggregates (such as marble, quartz, and glass fragments). It boasts advantages such as high wear resistance, diverse patterns, and moderate cost, making it widely used in commercial buildings, public facilities, and residential areas. However, traditional terrazzo flooring suffers from the following technical drawbacks:

[0003] Simple structure: Traditional terrazzo is mostly a single-layer cast structure, which relies on on-site construction and has a large thickness (usually ≥20mm), resulting in high material consumption, transportation and installation costs.

[0004] Cracks and deformation are common: Cement-based terrazzo is prone to micro-cracks due to its large area formed by one-time casting, curing shrinkage, and changes in temperature and humidity.

[0005] Insufficient functionality: Lacking composite properties such as sound insulation, moisture resistance, and impact resistance, it is difficult to meet the diverse needs of modern buildings for flooring.

[0006] Based on the above problems, we designed a multi-layer composite terrazzo floor that is easy to install, structurally stable, and has sound insulation and moisture-proof capabilities. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a multi-layer composite terrazzo floor that is easy to install, has a stable structure, and has sound insulation and moisture-proof capabilities.

[0008] To solve the above problems, the present invention adopts the following technical solution:

[0009] A multi-layer composite terrazzo floor includes a frame and terrazzo slabs cast inside the frame. A shock-absorbing pad is laid under the frame, and a waterproof membrane is laid under the shock-absorbing pad.

[0010] Preferably, the frame includes a body, which is rectangular, and support blocks are provided at the four outer corners of the body. A mold is supported by the support blocks, the mold is fitted to the outer wall of the body, and the upper end face of the mold extends beyond the upper end face of the body. The terrazzo slab is formed in the mold.

[0011] Preferably, a partition is provided inside the main body, the terrazzo slab is cast and formed on the upper part of the partition, and the interior of the main body, below the partition, is filled with a filling material.

[0012] Preferably, the filling material is a mixture of thermal insulation cotton and sound insulation cotton.

[0013] Preferably, an expansion sleeve is driven into the ground, and an expansion bolt is fitted through the expansion sleeve. The expansion bolt passes between adjacent support blocks, and a metal washer is fitted on the expansion bolt. The metal washer acts on the top of the support block, and the expansion bolt passes through the surface of the shock-absorbing pad and the waterproof membrane.

[0014] Preferably, the surface of the partition is provided with intersecting filling grooves, and a vertically penetrating drain hole is provided at the bottom of the filling groove, with a plunger detachably embedded in the drain hole.

[0015] The beneficial effects of this utility model are:

[0016] One advantage is that this product is a precast component. The frame and terrazzo slabs are cast in a factory and then transported to the construction site for on-site assembly, which reduces the construction cost of on-site construction. Since there is no need for on-site casting and curing, the construction time is shortened.

[0017] Secondly, the terrazzo slabs are formed within the frame, resulting in smaller dimensions compared to monolithic casting. This reduces the likelihood of small cracks and makes them more stable in use.

[0018] Thirdly, this product achieves waterproofing and moisture-proofing by laying waterproof membrane, and the shock-absorbing pads laid on top can absorb the positive impact on the terrazzo slab and achieve a certain degree of shock absorption and sound insulation.

[0019] Fourthly, this product has a simple structure, is easy to manufacture, and has low construction costs, making it suitable for widespread use. Attached Figure Description

[0028] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0029] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0030] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, in the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "socket," "connect," "through," and "plug-in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] See Figure 1 , Figure 2 , Figure 3 and Figure 4The terrazzo flooring shown is a multi-layer composite structure, including a frame 1 and terrazzo slabs 2 cast inside the frame 1. A shock-absorbing pad 3 is laid under the frame 1, and a waterproof membrane 4 is laid under the shock-absorbing pad 3.

[0034] In the above technical solution, the terrazzo slab 2 and the frame 1 are cast together, resulting in higher integrity and significantly reducing the probability of the terrazzo slab 2 cracking later.

[0035] By laying the shock-absorbing pad 3, a buffering and shock-absorbing effect can be achieved. Especially for multi-story floors, the laying of this shock-absorbing pad 3 can reduce the transmission of noise.

[0036] The waterproof membrane 4 is laid on the ground and located below the shock-absorbing pad 3, which serves as a waterproof protection.

[0037] See Figure 1 , Figure 5 and Figure 6 As shown, the frame 1 includes a body 101, which is rectangular. Support blocks 102 are provided at the four outer corners of the body 101. A mold 103 is supported by the support blocks 102. The mold 103 fits against the outer wall of the body 101. The upper surface of the mold 103 extends beyond the upper surface of the body 101. The terrazzo slab 2 is formed in the mold 103.

[0038] In the above technical solution, the mold 103 is a detachable structure. After the terrazzo slab 2 is cast and formed, the surface of the terrazzo slab 2 is polished, and the mold 103 is removed after polishing.

[0039] When using mold 103, a release agent needs to be brushed onto the inner wall to facilitate demolding after the concrete material has dried.

[0040] See Figure 4 and Figure 5 As shown, a partition 104 is provided inside the main body 101, the terrazzo slab 2 is cast and formed on the upper part of the partition 104, and the interior of the main body 101, below the partition 104, is filled with a filling material 5.

[0041] The function of partition 104 is to reduce the amount of concrete used when pouring terrazzo slab 2, thereby reducing the weight of the entire product without affecting the unique appearance of terrazzo slab 2.

[0042] By using filling material 5, sound insulation and heat preservation can be achieved.

[0043] The filling material 5 is a mixture of thermal insulation cotton and sound insulation cotton.

[0044] The mixing ratio of thermal insulation cotton and sound insulation cotton is 1:1.

[0045] See Figure 7 As shown, an expansion sleeve is driven into the ground, and an expansion bolt 6 is fitted through the expansion sleeve. The expansion bolt 6 passes between adjacent support blocks 102. A metal washer 61 is fitted on the expansion bolt 6. The metal washer 61 acts on the top of the support block 102. The expansion bolt 6 passes through the surface of the shock-absorbing pad 3 and the waterproof membrane 4.

[0046] The above technical solution is mainly to fix the frame 1 to the ground and prevent the product from becoming loose.

[0047] See Figure 5 As shown, a cross-shaped filling groove 144 is provided on the surface of the partition 104, and a vertically penetrating drain hole 145 is provided at the bottom of the filling groove 144. A plunger 146 is detachably embedded in the drain hole 145.

[0048] After the concrete is formed inside the mold 103, it needs to be watered for curing. Excess water can be drained through the drainage hole 105. In particular, if the curing personnel are not skilled enough, it is easy to spray too much water.

[0049] The installation steps for this product are as follows:

[0050] The first step is to clean the floor and remove any foreign objects.

[0051] The second step is to lay the waterproof membrane, which is laid as a whole.

[0052] The third step is to lay the shock-absorbing pads, which are also laid as a whole.

[0053] The third step is to lay the already cast-in-place frame and terrazzo slabs on the shock-absorbing pads and fix them with expansion bolts.

[0054] The fourth step is to fill the gaps between adjacent terrazzo slabs with grout.
