Abstract
Description
Technical Field
[0001] The present application relates to the technical field of building materials, and in particular to a reusable double-groove, single-groove, or triple-groove labor-saving strip. Background Art
[0002] During the exterior wall construction process, expansion joints need to be made, otherwise the stress of the wall cannot be released and the wall is very likely to crack, affecting the quality of the exterior wall plaster layer. In severe cases, the exterior wall plaster layer will crack and cause leakage.
[0003] At present, in most construction processes, it is necessary to embed the dividing strips, which can also play a decorative role to make the exterior wall more beautiful. Aluminum alloy grooves, PVC grooves, and sponge tapes are commonly used in the market. Aluminum alloy strips are not corrosion-resistant and are prone to cracking and leakage. Rainwater corrodes aluminum strips very quickly and the cost is high. Although PVC grooves are corrosion-resistant, they are not as solid as aluminum strips. The construction is more difficult and prone to cracking. Sponge strips have high requirements on the flatness of the substrate, which makes construction difficult and labor costs high. But the biggest advantage is that they do not stay in the wall and can be taken out after construction is completed. Labor-saving strips can replace sponge strips, and they are simple to construct and low in cost. Utility Model Content
[0004] In order to solve the above problems, improve the quality of the project and avoid cracking of the exterior wall, while reducing the construction cost, the present application provides a reusable double-groove, single-groove, and triple-groove labor-saving strip.
[0005] The present application provides a reusable double-groove, single-groove, and triple-groove labor-saving strip that adopts the following technical solution.
[0006] A reusable double-groove, single-groove or triple-groove work-saving strip comprises an inner base and an outer base arranged on one side of the inner base, wherein the width of the outer base is greater than that of the inner base.
[0007] By adopting the above technical solution, through the arrangement of the inner matrix and the outer matrix, the labor-saving strip can be fixed on the wall according to the line during construction, and the anti-cracking mortar is applied based on the labor-saving strip to smooth and straighten it. Excess mortar is removed, and the mortar is removed after solidification, leaving a groove on the wall to complete the construction. At the same time, the inner matrix is hollow and has reinforcing ribs inside, which improves the overall strength and hardness of the labor-saving strip. The labor-saving strip is easy to use and can be reused, which is conducive to reducing construction costs.
[0008] Optionally, the inner substrate is located at the center of the width of the outer substrate, and the outer substrate and the inner substrate are aligned at both ends.
[0009] By adopting the above technical solution, the structural setting can make the grooves after construction symmetrical and uniform, more beautiful, and easy to construct.
[0010] Optionally, the cross section of the inner matrix is trapezoidal.
[0011] By adopting the above technical solution, the trapezoidal cross-sectional shape is more conducive to the removal of the inner matrix after the mortar solidifies, and also avoids damage to the groove and the work-saving strip during removal.
[0012] Optionally, the inner matrix and the outer matrix are an integral structure.
[0013] By adopting the above technical solution, the integrated structural design has better strength.
[0014] Optionally, the outer matrix is hollow.
[0015] By adopting the above technical solution and setting up a hollow structure, the use of materials can be reduced and the cost of labor saving strips can be reduced.
[0016] Optionally, the inner matrix and the outer matrix are any one of PVC foam material and PE foam material.
[0017] In summary, this application at least includes the following beneficial effects:
[0018] The present application sets an inner matrix and an outer matrix of an integrated structure. During construction, the labor-saving strip can be fixed on the wall according to the line, and the anti-cracking mortar is applied based on the labor-saving strip to smooth and straighten it. Excess mortar is removed, and the mortar is removed after solidification, leaving a groove on the wall to complete the construction. At the same time, both the inner matrix and the outer matrix are hollow, which reduces the use of materials and reduces costs. The inner matrix is provided with reinforcing ribs to improve the overall strength and hardness. The labor-saving strip is easy to use and can be reused, which is conducive to reducing construction costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0035] The following is combined with Figures 1 to 13 This application is described in further detail.
[0036] The embodiments of the present application disclose a reusable double-groove, single-groove, or triple-groove labor-saving strip.
[0037] Reference Figures 5 to 13The groove of the work-saving strip can be arc-shaped, flat, arched, semicircular or stepped.
[0038] Labor-saving strips can also be called reused double buckle strips, model strips, plastic buckle strips, plastic model strips or plastic double buckle strips.
[0039] Reference Figures 1 to 4 A reusable double-groove, single-groove, or triple-groove labor-saving strip includes an inner substrate 1 and an outer substrate 2 arranged in an integrated structure, which are made of PVC foam or PE foam material, and the integrated structure design has better strength.
[0040] The outer matrix 2 is located on one side of the inner matrix 1, the width of the outer matrix 2 is greater than the width of the inner matrix 1, the inner matrix 1 is located at the center of the width of the outer matrix 2, and the two ends of the outer matrix 2 and the inner matrix 1 are aligned. This structural setting can make the grooves after construction symmetrical and uniform, more beautiful, and easy to construct, avoiding unnecessary mortar filling and removal.
[0041] The inner matrix 1 and the outer matrix 2 are both hollow, and the hollow structure can reduce the use of materials and reduce the cost of labor.
[0042] The overall cross-section of the work-saving strip is in a convex shape.
[0043] The inner base 1 has rounded corners, which is more conducive to the removal of the labor-saving strip after the mortar solidifies, and is more conducive to construction operations. A rounded structure is also formed at the corresponding mortar groove position, which is conducive to improving the structural strength of the mortar layer and is not easy to crack.
[0044] By setting the inner matrix 1 and the outer matrix 2, the labor-saving strip can be fixed on the wall according to the line during construction, and the anti-cracking mortar is applied based on the labor-saving strip to smooth and straighten it. Excess mortar is removed, and the mortar is removed after solidification, leaving a groove on the wall to complete the construction. The labor-saving strip is easy to use and can be reused, which is conducive to reducing construction costs.
[0045] Use of this provincial work article:
[0046] Apply the anti-cracking mortar on the wall according to the width of the labor-saving strip, and then paste the labor-saving strip along the line, remove the excess mortar, ensure that the mortar at the bottom of the labor-saving strip is full, and there is no residual ash on the surface of the labor-saving strip. The mortar cannot be higher than the labor-saving strip. After the mortar is completely solidified, remove the labor-saving strip to form a groove, i.e., the partition joint. If the mortar at the bottom of the labor-saving strip is not filled and there are defects, the solution is to apply a small amount of thin mortar to the defective part, and repair and level it repeatedly.
[0047] To save labor, only horizontal lines are made.
[0048] Construction method:
[0049] ① If you are making a work grid, use anti-cracking mortar to make dots on the back of the work-saving strip every 20 cm or so, and paste it along the line, first sticking the vertical and then the horizontal. The horizontal and vertical can be directly connected, and the connection points must be aligned, straight and flat.
[0050] After the labor-saving strips are solidified, fill the frame with mortar. The mortar should be applied thinly and multiple times to prevent cracks on the wall. Then plaster the large surface and remove the labor-saving strips after the mortar is completely solidified.
[0051] ② After the labor-saving strip is taken out, marks may appear on the bottom dotted parts, or the bottom mortar is not filled and leveled. The solution is: use a small amount of fine anti-cracking mortar to fill the defective parts, and use the original strip to repair and level the groove to achieve our ideal effect.
[0052] ③ The labor-saving strip can be cut if it is too long, and can be connected if it is too short. To prevent the interface from shifting, you can use tape or labels to stick the interface horizontally.
[0053] ④ The mortar cannot be higher than the labor-saving strip. Take out the labor-saving strip after the mortar is completely solidified. After taking it out, there will be about 2 centimeters of mortar blocking the horizontal and vertical joints, making it impossible to connect the seams. You can use a small iron saw to remove it to achieve the effect of connecting the seams.
[0054] Note: Ensure the verticality of the labor-saving strip. If the wall height is 3 meters or more, hanging wire construction is required.
[0055] Advantages of this provincial work article:
[0056] 1. It can be used as reinforcement when leveling the red brick wall base;
[0057] 2. Reusable, reducing costs;
[0058] 3. The labor-saving strip will not be left in the wall, will not cause cracks, and will not leave any hidden dangers.
[0059] 4. The construction is simple and efficient.
[0060] 5. The labor-saving strips do not need special protection during the construction process, are not afraid of pollution, and do not need to be cleaned. Other PVC strips and aluminum strips need to be cleaned, which is labor-intensive and time-consuming, and incomplete cleaning affects the appearance.
