Description

Technical Field

[0001] The utility model relates to the technical field of cement blankets, and particularly relates to a reinforced cement blanket. Background Art

[0002] In engineering construction such as buildings, roads, ditches, etc., cement blankets are often used as waterproof materials. The structure of the existing cement blanket is to fill cement between two layers of woven fabrics, and then connect the two layers of woven fabrics through needling technology. A waterproof cloth or a waterproof plastic film is pasted under the lower woven fabric, and the waterproofing is carried out jointly by the reaction and condensation of cement and water and the waterproof cloth or the waterproof plastic film. However, the waterproof cloth or the waterproof plastic film is pasted on the woven fabric through an adhesive, and the connection between the two is not firm. Over time, the waterproof cloth or the waterproof plastic film is likely to fall off. Content of the Utility Model

[0003] In order to solve the technical problems existing in the above background art, the utility model provides a reinforced cement blanket.

[0004] The technical solution of the utility model is as follows:

[0005] A reinforced cement blanket, comprising:

[0006] A filling layer, which is filled with a cement mixture;

[0007] A waterproof layer, located below the filling layer, which comprises a waterproof plate body and a plurality of plugging columns. The upper surface of the waterproof plate body is pasted on the lower surface of the filling layer, and a plurality of plugging columns protrude upward from the upper surface of the waterproof plate body and are inserted into the cement mixture;

[0008] The plugging column comprises a vertical column body and a hooking portion arranged on the column body. The hooking portion extends to the outside of the column body, and the extending direction is not vertical. The cross-sectional dimension of the top of the hooking portion is smaller than that of the middle or the lower part.

[0009] The waterproof layer is first pasted on the lower surface of the filling layer through an adhesive, and the plugging columns are inserted into the cement mixture. When the cement mixture encounters water and solidifies, the cement mixture will be fixed together with the plugging columns. Through the clamping connection between the hooking portion of the plugging column and the cement mixture, the waterproof layer is fixed on the filling layer. Therefore, the cement blanket of the present application not only fixes the waterproof layer through the adhesive, but also fixes the waterproof layer through the solidified cement mixture, so that the waterproof layer is firmly fixed on the filling layer and will not fall off even after long-term use.

[0010] In the above solution, the filling layer adopts a double-layer three-dimensional fabric. The double-layer three-dimensional fabric comprises an upper fabric and a lower fabric, and the two fabrics are connected and supported by fiber filaments to form a hollow three-dimensional shape, and its structural strength is high.

[0011] Preferably, the lower surface of the filling layer is a mesh surface, that is, the lower-layer fabric is a mesh fabric, which is used for filling cement concrete and for the insertion columns to be inserted. The upper surface is a non-mesh surface, that is, the upper-layer fabric is a non-mesh fabric without mesh holes, which is used to prevent the leakage of the cement mixture and downward seepage of water.

[0012] In this application, several insertion columns correspond to the mesh holes on the lower surface of the filling layer and are arranged in an array.

[0013] In order to make the insertion column not easily pulled out of the filling layer, the maximum size of the vertical projection of the hook connection part is greater than the aperture of the mesh hole on the lower surface of the filling layer. When the insertion column is inserted into the filling layer, the hook connection part will expand the mesh hole on the lower surface of the filling layer and enter the filling layer. At this time, if the waterproof layer is moved downward, the hook connection part will form a clamping relationship with the mesh hole on the lower surface of the filling layer, hindering the pulling out of the insertion column.

[0014] As a preferred solution of this application, the hook connection part is arranged at the upper end of the column body, and the top surface is a spherical surface or a conical surface that protrudes upward, so as to facilitate expanding the mesh hole on the lower surface of the filling layer and enable the insertion column to be smoothly inserted into the filling layer.

[0015] Preferably, the combined vertical cross-sectional shape of the hook connection part and the column body is in the shape of an inverted hook with the opening facing downward. If the waterproof layer is moved downward, the hook connection part can be stuck on the edge of the mesh hole on the lower surface of the filling layer, making the insertion column not easily pulled out of the filling layer.

[0016] As another preferred solution of this application, the hook connection part is strip-shaped and extends obliquely downward from the upper end of the column body. The hook connection part and the column body form an inverted J shape or an anchor shape, which not only facilitates expanding the mesh hole on the lower surface of the filling layer and enables the insertion column to be smoothly inserted into the filling layer, but also can hook the edge of the mesh hole on the lower surface of the filling layer when the waterproof layer is moved downward, so that the insertion column cannot be pulled out of the filling layer without human intervention.

[0017] In order to improve the clamping strength between the insertion column and the cement mixture, at least one hook connection strengthening part is provided on the column surface of the column body, and the shape of the hook connection strengthening part is the same as that of the hook connection part. By sharing the fixing force on the column body jointly by the hook connection part and the hook connection strengthening part, the damage probability of the insertion column is reduced, and further the connection strength between the waterproof layer and the filling layer is improved, making the waterproof layer not easily fall off.

[0018] A reinforced cement blanket provided by the utility model enables the insertion column with a hook connection part to extend into the cement mixture in the filling layer through arranging the insertion column with a hook connection part on the waterproof layer. After the cement mixture is cured, it is fixed together with the insertion column, and the waterproof layer is fixed by the cured cement mixture, so that the waterproof layer is firmly fixed on the filling layer and will not fall off even after long-term use.

[0027] As Figure 1 shown, the first embodiment of the present utility model provides a reinforced cement blanket, including:

[0028] A filling layer 1 filled with a cement mixture 11;

[0029] A waterproof layer 2 located below the filling layer 1, which includes a waterproof plate body 21 and a plurality of insertion columns 22. The upper surface of the waterproof plate body 21 is adhered to the lower surface of the filling layer 1, and the plurality of insertion columns 22 protrude upward from the upper surface of the waterproof plate body 21 and are inserted into the cement mixture 11;

[0030] The insertion column 22 includes a vertical column body 221 and a hook connection part 222 provided on the column body 221. The hook connection part 222 extends outward from the column body 221, and the extension direction is not vertical. The cross-sectional dimension of the top of the hook connection part 222 is smaller than that of the middle or lower part.

[0031] The waterproof layer 2 is first adhered to the lower surface of the filling layer 1 by an adhesive, and the insertion column 22 is inserted into the cement mixture 11. When the cement mixture 11 undergoes condensation and curing upon contact with water, the cement mixture 11 will be fixed together with the insertion column 22. Through the clamping connection between the hook connection part 222 of the insertion column 22 and the cement mixture 11, the waterproof layer 2 is fixed on the filling layer 1.

[0032] The cement blanket of the present application not only fixes the waterproof layer 2 by an adhesive, but also fixes the waterproof layer 2 by the cement mixture 11 after condensation and curing, so that the waterproof layer 2 is firmly fixed on the filling layer 1, and no peeling problem will occur even after long-term use.

[0033] The filling layer 1 is made of double-layer three-dimensional fabric. The double-layer three-dimensional fabric includes an upper layer of fabric and a lower layer of fabric. The two layers of fabric are connected and supported by fiber filaments to form a hollow three-dimensional shape with high structural strength. The double-layer three-dimensional fabric can be made of polyester fiber or glass fiber.

[0034] Specifically, the lower surface of the filling layer 1 has mesh holes, that is, the lower fabric is woven to form mesh holes for filling cement concrete and inserting the plug-in column 22. The upper surface of the filling layer 1 has no mesh holes, that is, the upper fabric is finely woven to prevent the cement mixture 11 from leaking and seeping downward.

[0035] The cement mixture 11 can be any composition and ratio configuration in the prior art. When filling the cement mixture 11 into the filling layer 1, a vibration device can be used to fill the cement mixture 11 evenly in the filling layer 1.

[0036] The waterproof layer 2 is made of waterproof materials such as PVC or HDPE, and the waterproof plate body 21, the column 221 and the hooking part 222 are integrally formed. A plurality of plug-in columns 22 correspond to the mesh holes on the lower surface of the filling layer 1 and are arranged in an array.

[0037] A conical platform is provided between the lower end of the plug-in column 22 and the waterproof plate body 21 to strengthen the structural strength of the connection between the plug-in column 22 and the waterproof plate body 21 to avoid tearing and breaking.

[0038] The hooking part 222 is arranged at the upper end of the column 221, and the maximum size of its vertical projection is larger than the mesh aperture of the lower surface of the filling layer 1. Therefore, if the waterproof layer 2 moves downward, the hooking part 222 will form a snap-fit ​​relationship with the mesh aperture of the lower surface of the filling layer 1, hindering the withdrawal of the plug-in column 22, making it difficult for the plug-in column 22 to be withdrawn from the filling layer 1, and further making it difficult for the waterproof layer 2 to fall off from the filling layer 1. In the present application, since the filling layer 1 is a woven fabric, it has a certain degree of stretchability. When the plug-in column 22 is inserted into the filling layer 1, the hooking part 222 can open the mesh aperture of the lower surface of the filling layer 1 and enter the filling layer 1.

[0039] In this embodiment, the hooking portion 222 is in a cap shape, and the top surface is a spherical surface that bulges upward, so as to facilitate opening the mesh holes on the lower surface of the filling layer 1 and inserting it into the filling layer 1.

[0040] See also Figures 2 to 5 Except for the shape of the plug-in column, the other structures of the second to fifth embodiments are the same as those of the first embodiment.

[0041] In the second embodiment, the hooking portion 222 is in a cap shape, and the top surface is a conical surface convex upward.

[0042] In the first and second embodiments, the combined vertical cross-sectional shape of the hook connection part 222 and the column 221 is an inverted hook shape with the opening facing downward. If the waterproof layer 2 moves downward, the hook connection part 222 can be stuck on the edge of the mesh hole on the lower surface of the filling layer 1, making it difficult for the plug-in column 22 to be pulled out from the filling layer 1.

[0043] In the third embodiment, the hook connection part 222 is strip-shaped, one end of which is connected to the upper end of the column 221, and the other end extends obliquely downward, forming an inverted J shape with the column 221. This not only facilitates opening the mesh hole on the lower surface of the filling layer 1 to enable the plug-in column 22 to be smoothly inserted into the filling layer 1, but also can hook the edge of the mesh hole on the lower surface of the filling layer 1 when the waterproof layer 2 moves downward, so that the plug-in column 22 cannot be pulled out of the filling layer 1 without human intervention.

[0044] In the fourth embodiment, the hook connection part 222 is also strip-shaped, but its middle part is connected to the upper end of the column 221, and both ends extend obliquely downward, forming an anchor shape with the column 221.

[0045] In the fifth embodiment, the hook connection part 222 can also be ellipsoidal or spherical.

[0046] In addition, in order to improve the clamping strength between the plug-in column 22 and the cement mixture 11, at least one hook connection strengthening part 223 is provided on the column surface of the column 221. The shape of the hook connection strengthening part 223 is the same as that of the hook connection part 222, as Figure 2 shown. By jointly sharing the fixing force of the cement mixture 11 on the column 221 by the hook connection part 222 and the hook connection strengthening part 223, the damage probability of the plug-in column 22 is reduced, thereby improving the connection strength between the waterproof layer 2 and the filling layer 1 and making it difficult for the waterproof layer 2 to fall off.

[0047] In addition, the heights of the plug-in columns 22 can be set differently. Higher plug-in columns 22 are arranged on both sides or around the shorter plug-in columns 22. Additionally, according to the height change of the plug-in columns 22, the heights of the plug-in columns 22 can be arranged in a wavy pattern in both horizontal and vertical directions. In this way, while ensuring that the waterproof layer 2 is firmly connected to the filling layer 1, the materials required for manufacturing the waterproof layer 2 are saved and the cost is reduced.
