An integrated inclined wrapped stone strip floor reinforcement structure

Abstract

The present invention discloses an integrated inclined wrapped stone strip floor reinforcement structure in the technical field of wrapped stone strip floor reinforcement structure, comprising strip stone slabs, high-strength steel wire mesh, carbon fiber grid, and special mortar (carbon fiber grid / high-strength steel wire mesh). The reinforcement range is a local area of ​​1 / 3-1 / 2 of the floor span, and the entire stone floor is wrapped horizontally and inclined at a certain angle from the lower surface to the upper surface with an uninterrupted carbon fiber grid / high-strength steel wire mesh, and the carbon fiber grid / high-strength steel wire mesh is bonded to the stone floor with a special mortar as a base layer. This reinforcement scheme uses high-strength steel wire / carbon fiber grid to perform integrated inclined wrapped reinforcement on the stone strip floor, thereby enhancing the coordinated force-bearing performance of the strip stone in the stone floor. At the same time, by adding longitudinal reinforcement measures at the bottom of the wrapped strip stone, the overall bearing capacity of the stone floor can be further improved. The scheme is simple to operate and low in cost, and therefore has wide engineering application and promotion value.

Description

Technical Field

[0001] The present invention relates to the technical field of wrapped stone strip floor reinforcement structures, in particular to an integrated inclined wrapped stone strip floor reinforcement structure. Background Art

[0002] In coastal Fujian Province, my country, stone slabs are commonly used for flooring, often assembled from stone slabs. However, stone is a brittle material, often exhibiting natural cracks and prone to brittle fracture. Therefore, stone structures present certain safety risks. Demolition and reconstruction would destroy the unique architectural and residential culture of southern Fujian. Therefore, the reinforcement and repair of stone structures is particularly urgent. While existing stone slab reinforcement technologies have proven effective in theory or through laboratory testing, their practical application in real projects is limited due to complex procedures, significant damage to the stone, impractical reinforcement conditions, and high costs.

[0003] Based on this, the present invention designs an integrated inclined wrapped stone strip floor reinforcement structure to solve the above problems. Summary of the Invention

[0004] The purpose of the invention is to provide an integrated inclined wrapped stone strip floor reinforcement structure to solve the above technical problems.

[0005] To achieve the above-mentioned purpose, the invention provides the following technical solution: an integrated inclined wrapped stone strip floor reinforcement structure, characterized in that it includes strip stones, carbon fiber grid / high-strength steel wire mesh and special mortar, wherein the special mortar is used as a base layer to bond the carbon fiber grid / high-strength steel wire mesh to the stone strip floor.

[0006] Preferably, the carbon fiber grid / high-strength steel wire mesh in the reinforcement area is a carbon fiber grid / high-strength steel wire mesh with a certain width and no interruption in the middle.

[0007] Preferably, the carbon fiber grid / high-strength steel wire mesh in the reinforcement area is laid horizontally along the stone floor slab, and is laid from its lower surface at a certain angle to the edge of the stone floor slab, and then passes through the gap at the edge of the stone floor slab to reach the upper surface, and is repeatedly wrapped to form an overall wrapping of the stone floor slab.

[0008] Preferably, if the stone slabs on both sides of the wall edges cannot be wrapped, they can be left untreated because they are usually subjected to less stress, that is, they are not wrapped in the integrated reinforcement area.

[0009] Preferably, the carbon fiber grid / high-strength steel wire mesh reinforcement area is in the local area of ​​1 / 3-1 / 2 of the floor span, and the local arrangement area of ​​the carbon fiber grid / high-strength steel wire mesh is wrapped with at least two circles of carbon fiber grid / high-strength steel wire mesh belt.

[0010] Preferably, the carbon fiber grid / high-strength steel wire mesh passes through the gaps between the strip-shaped stones and reaches the upper and lower surfaces of the strip-shaped stones.

[0011] Preferably, before the carbon fiber grid / high-strength steel wire mesh is integrally wrapped, several longitudinal high-strength steel wires / carbon fiber grids can be bonded along the bottom of the strip stone, and then the overall ductility and bearing capacity of the stone floor can be improved simultaneously through the above-mentioned integral wrapping method.

[0012] Compared with the prior art, the invention has the following beneficial effects:

[0013] The present invention utilizes an uninterrupted carbon fiber grid / high-strength steel wire mesh to obliquely wrap the stone floor slab, thereby improving the overall anti-collapse capability, coordinated deformation capability, and bearing capacity of the stone floor slab. The integrated wrapping makes the carbon fiber grid / high-strength steel wire mesh less likely to peel off. When a strip of stone breaks, the wrapped carbon fiber grid / high-strength steel wire mesh prevents it from falling, and the remaining strips of stone can quickly redistribute internal forces, thereby improving the integrity and anti-collapse capability of the stone floor slab. Furthermore, by adding longitudinal reinforcement measures to the bottom of the wrapped strips of stone, the overall bearing capacity of the stone floor slab can be further enhanced. This reinforcement scheme has relatively simple construction procedures and operations, and the reinforcement cost is low, making it very suitable for promotion and application in actual projects.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0022] Example 1 Figure 1-2 As shown, the integrated inclined wrapped stone strip floor reinforcement solution includes stone strips 1, high-strength steel wire mesh 3, and special mortar 2. The stone floor is entirely obliquely wrapped with high-strength steel wire mesh 3. The integrated high-strength steel wire mesh forms a wrapping ring that is difficult to peel off and enhances the synergistic load-bearing performance of the individual stone strips, thereby improving the stone floor's overall resistance to progressive collapse.

[0023] In Example 1, the integrated inclined wrapping method is as follows: the high-strength steel wire mesh 3 is cut into a suitable width, the starting end is 1 / 3-1 / 2 of the width of a single strip stone on the upper surface of the edge strip stone 1, passes through the gap at the edge of the stone floor slab to reach the lower surface, and then tilts horizontally at a certain angle on the plane of the lower surface to the other edge of the stone floor slab, passes through the gap at the other edge of the stone floor slab to reach the upper surface of the stone floor slab, repeats the inclined wrapping and passes through the gap at the edge of the stone floor slab, after wrapping three and a half times (the number of wrapping times can be based on the actual needs of the project), the end is laid the same as the starting end.

[0024] In Example 1, the integrated inclined wrapping stone strip floor reinforcement solution is implemented as follows: (1) Apply a layer of special mortar 2 to the gaps between the stone strips 1 and the upper and lower surfaces of the stone floor. (2) Perform an integrated inclined wrapping. (3) Press a layer of special mortar 2 onto the wrapped high-strength steel wire mesh 3 to cover the high-strength steel wire mesh 3, and also fill the gaps at the edges of the stone floor with special mortar 2.

[0025] In Example 1, the reinforcement range is the 1 / 3-1 / 2 span area in the middle of the span.

[0026] In Example 1, the reinforcement scheme covers all the strip stones in the same bay. If the strip stones on both sides of the wall edge cannot be covered, they can be left untreated because they are usually less stressed.

[0027] In Example 1, the solution covers the entire reinforcement area with the special mortar 2, or only the area where the high-strength steel wire mesh 3 is laid is coated with the special mortar 2.

[0028] Example 2 Figure 3-4 As shown, before implementing Example 1, a plurality of longitudinal carbon fiber grids 4 are bonded along the bottom of the strip stone 1, and then Example 1 is implemented on this basis to achieve the purpose of simultaneously improving the overall ductility and bearing capacity of the stone floor slab.

[0029] The implementation method of Example 2 is as follows: (1) Apply a layer of special mortar 2 to the lower surface of the reinforcement area of ​​the strip stone 1 to be longitudinally reinforced. (2) Lay a carbon fiber mesh 4 with the same width as the strip stone and the reinforcement range of 1 / 3-1 / 2 of the span of the strip stone on the special mortar 2. (3) Press a layer of special mortar 2 on the carbon fiber mesh 4 to cover it. (4) After the special mortar 2 has initially set, apply a layer of special mortar 2 to the gaps between the strip stone 1 and the upper and lower surfaces of the stone floor. (5) Perform an integrated inclined wrapping. (6) Press a layer of special mortar 2 on the wrapped high-strength steel wire mesh 3 to cover the high-strength steel wire mesh 3, and fill the gaps at the edges of the stone floor with special mortar 2.

[0030] It should be noted that the carbon fiber mesh pasted for longitudinal reinforcement of the strip stone in Example 2 can be replaced by a high-strength steel wire mesh or other high-strength fibers.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solutions of the present invention. They should all be included in the scope of the technical solutions claimed for protection by the present invention.
