[0001] This utility model relates to the field of terrazzo floor installation technology, specifically to a terrazzo floor inlay strip and its auxiliary installation device. Background Technology

[0002] The terrazzo market is currently experiencing a positive development trend, with a wide variety of products available, such as water-based terrazzo, gold-plated terrazzo, crystal terrazzo, and epoxy terrazzo. Water-based terrazzo is characterized by its aesthetic appeal, durability, environmental friendliness, cost-effectiveness, and wide applicability. It holds a significant market share in interior decoration and construction. To enhance the aesthetics of terrazzo floors and prevent large-area deformation and cracking, terrazzo floors are typically divided into sections using inlay strips. Sectioning lines are drawn according to the dimensions in the construction drawings, and workers use cement to fix the inlay strips. The terrazzo is poured only after the cement has reached the required strength.

[0003] However, the installation of inlay strips is greatly affected by the skill level of the workers, resulting in inconsistent installation quality. This is especially true when horizontal and vertical inlay strips intersect, where installation quality issues are particularly prominent, often leading to misalignment, height differences, and other problems. Inlay strip issues directly affect the aesthetics of the terrazzo surface. Summary of the Invention

[0027] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] In the description of this utility model, it should be noted that the terms "middle," "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used 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. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example 1

[0029] like Figures 1-3 As shown, a terrazzo flooring strip is provided. The strip 1 includes a strip body 101 and an insert strip 102 disposed below the strip body 101. The width of the insert strip 102 is smaller than the width of the strip body 101, and the vertical height of the insert strip 102 is not less than the vertical height of the strip body 101. Multiple first reserved protrusions 103 are provided on both sides of the insert strip 102, and the first reserved protrusions 103 are arranged along the length direction of the insert strip 102.

[0030] This terrazzo flooring strip has undergone structural improvements to facilitate installation, enhancing the quality and aesthetics of the installation and preventing issues such as misaligned joints and height differences.

[0031] The insertion strip 102 is provided below the main body 101 of the inlay strip, which can further improve the stability and accuracy of its connection and installation. By connecting the insertion strip to the groove of the auxiliary installation device pre-installed in the terrazzo floor, the installation position and laying path of the inlay strip main body can be limited and positioned, allowing it to be laid according to the preset path. The first reserved protrusion serves as a limiting element during installation.

[0032] The cross-sectional width of the insert strip 102 is about 1 / 3 of the cross-sectional width of the insert strip body 101, and the cross-sectional length (that is, the vertical height) is much larger than that of the insert strip body. This ensures the insertion depth of the insert strip and prevents gaps from appearing due to its width.

[0033] Furthermore, each side has at least one pair of first reserved protrusions 103 arranged vertically, and the first reserved protrusions 103 on the left and right sides are arranged symmetrically. The first reserved protrusions 103 on the upper and lower sides are respectively spaced with the end of the plug strip 102 at the corresponding end, that is, they are not set at the end position. The purpose of this arrangement is to provide space for installation and limiting, so as to facilitate use with the second reserved protrusion in the auxiliary installation device.

[0034] Furthermore, the first reserved protrusion 103 is an arc-shaped or semi-circular protrusion, which can form an arc-shaped transition surface, which is beneficial for insertion and snap-fit.

[0035] Furthermore, the length of the insert strip 102 is not longer than the length of the insert body 101, and the insert strip 102 is a whole strip structure arranged along the length direction of the insert body 101, or a multi-segment structure arranged at intervals.

[0036] Furthermore, the cross-sections of the insert body 101 and the connector 102 are rectangular structures, the cross-section of the insert body 101 is approximately square, and the cross-section of the connector 102 is a long and narrow rectangle. The insert body 101 and the connector 102 are also integrally formed structures, which can be mass-produced using molds. Example 2

[0037] This embodiment provides an auxiliary installation device for terrazzo floor strips, which can assist in the installation of the strips in Embodiment 1; combined with Figures 4-7 As shown, the auxiliary installation device includes a strip fixing assembly 2 and a screw 3. The strip fixing assembly 2 includes a fixing connecting block 201 and a cross mounting strip 202 disposed on the fixing connecting block 201. The fixing connecting block 201 is connected to the screw 3. The cross mounting strip 202 is provided with a cross mounting groove 203 for connecting the plug strip 102. The inner wall of the cross mounting groove 203 is provided with a plurality of second reserved protrusions 204 that cooperate with the first reserved protrusion 103.

[0038] This auxiliary installation device, through the setting of the inlay strip fixing component 2 and the screw 3, can solve the problems of misalignment, height difference and inaccurate intersection of inlay strips caused by the low skill level of workers during the installation of terrazzo inlay strips. It greatly reduces the installation problems caused by the skill level and experience of workers, reduces the dependence on installation experience, makes the installation of inlay strips easy to learn and less prone to errors, and has high installation accuracy, quality and efficiency, as well as good aesthetics.

[0039] The screw 3 is designed to be driven into the ground according to the position of the cross intersection. After the insert fixing component 2 is installed on it, the accuracy of the position of the cross intersection can be ensured. The cross mounting strip 202 provided on the insert fixing component 2 can be arranged along the direction of the cross intersection to ensure the accuracy of the cross path. The installation accuracy of the insert can be guaranteed by connecting the insert 1 with the cross mounting groove 203.

[0040] In other words, the screw 3 and the fixing block 201 solve the problem of inaccurate cross-shaped intersection position; the cross-shaped mounting strip 202 and the cross-shaped mounting groove 203 solve the problem of misalignment during the installation of the insert strip 1; the cooperation between the insert strip 102 and the cross-shaped mounting groove 203, as well as the cooperation between the first reserved protrusion 103 and the second reserved protrusion 204, solve the problem of height difference during the installation of the insert strip. This auxiliary installation device not only solves these problems but also overcomes the difficulty of installation, making the installation of the insert strip simpler and more efficient.

[0041] Furthermore, the second reserved protrusions 204 on both sides are respectively disposed on the inner wall of the cross mounting groove 203. The number of the second reserved protrusions 204 is the same as that of the first reserved protrusions 103. The first reserved protrusions 103 are engaged below the second reserved protrusions 204.

[0042] By providing the second reserved protrusion 204 on the inner wall of the cross mounting groove 203, when the insert strip 102 is inserted into the cross mounting groove 203, the first reserved protrusion 103 will pass through the second reserved protrusion 204 and be engaged below the second reserved protrusion 204, forming an upper and lower engagement and limiting structure. This can effectively connect the insert strip and fix it on the cross mounting groove to prevent it from falling off.

[0043] The pair of second reserved protrusions located at the top are positioned near the port of the cross mounting slot. When they mate with the first reserved protrusion, they are positioned between the first reserved protrusion and the lower surface of the insert body, which makes the connection and installation of the insert body more stable and reliable.

[0044] Furthermore, the central axes of the cross mounting strip 202 and the cross mounting groove 203 are coaxially arranged with the fixed connecting block 201 and also coaxial with the central axis of the screw 3. This arrangement is to ensure the uniformity of the cross intersection point.

[0045] Furthermore, the fixed connecting block 201 has an internal thread in the middle for connecting the screw 3.

[0046] Furthermore, the screw 3 is a fully threaded screw without a prominent end, which allows it to be better connected to the fixed connection block. One end of the screw 3 is provided with a notch 301 and the other end is a pointed tip. The notch 301 facilitates the use of tools to drive it into the concrete pad layer.

[0047] The screw 3 is effectively driven into the concrete pad 5 of the ground, and the depth of the screw 3 into the soil is not less than 15mm. If the flatness deviation of the concrete pad 5 is large and the depth of the fully threaded screw into the soil cannot be guaranteed, the length of the fully threaded screw can be increased.

[0048] The insert fixing component 2 is fixed to the screw 3 by tightening. The upper opening height of the insert fixing component 2 is related to the height of the insert 1. The thread size of the screw 3 and the insert fixing component 2 should be matched.

[0049] One method of using this terrazzo floor inlay strip auxiliary installation device is as follows:

[0050] (1) Mark the grid lines of the concrete subfloor according to the design drawings and determine the cross points of the grid.

[0051] (2) Drive the screw 3 into the cross point of the ground. The depth of the screw 3 is determined according to the height of the insert 1. Specifically, the height of the top surface of the screw 3 is the finished surface of the ground minus the height of the insert.

[0052] (3) Then tighten the strip fixing component 2 onto the screw 3. Adjust the depth of the strip fixing component 2 according to the height of the terrazzo finished surface. Note that the cross direction of the strip fixing component 2 should correspond to the cross direction of the ground grid line.

[0053] (4) Press the insert 1 into the insert fixing assembly 2, that is, insert the connector into the cross mounting groove, until it is firmly locked in place (see Figure 1 ).

[0054] (5) After the installation of the insert strip 1 is completed, all insert strips are reinforced with white cement.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
