Description

Technical Field

[0001] This utility model relates to the field of stone structure building technology, and more specifically, to a reinforcement structure for stone walls. Background Technology

[0002] Stone structures are one of the main forms of residential and highway construction. In the Minnan region of Fujian Province, the walls of stone masonry houses are mainly made of rubble stone. The internal mortar layer of the existing rubble stone walls is mainly clay-mixed mortar, which has low strength, poor mortar joint fullness, and dry-laying and mortar-spreading construction method, resulting in poor seismic performance of the walls. Under the action of earthquake, the walls may be damaged along the mortar joints, leading to the collapse of the entire structure. Therefore, it is necessary to reinforce and renovate the rubble stone walls in existing stone houses to improve the seismic performance of the walls and the overall integrity of the stone structure houses. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a reinforcement structure for stone walls, which can strengthen the structural strength of existing stone walls and improve their shear and seismic resistance.

[0004] To solve the above problems, the present invention adopts the following technical solution.

[0005] A reinforcement structure for a stone wall includes horizontal mortar joints and vertical grooves formed on the sides of any unit stone in the stone wall. At least two horizontal grooves are symmetrically arranged at the horizontal mortar joints on both sides of any unit stone, and at least one vertical groove is symmetrically arranged at the vertical mortar joints on both sides of any unit stone. Several tie bars are also provided. Each tie bar extends through the mortar layer of the stone wall into the symmetrically arranged horizontal or vertical grooves. Each horizontal and vertical groove is filled with ultra-high performance concrete, which forms a reinforcement layer after solidification.

[0006] Furthermore, each of the tie bars is also provided with an external support at both ends. The external support is in the shape of an inverted cone and slides along the tie bar into the horizontal or vertical inner groove. Each of the horizontal and vertical inner grooves is filled in two stages by grouting. After the first stage of grouting, the external support is pressed in until it is submerged, and then the second stage of grouting is performed to fill it.

[0007] Furthermore, the outer support member is arranged in the shape of an inverted conical column, and a sliding hole is provided in the middle of the outer support member to slide and connect with the tie bar.

[0008] Furthermore, the outer support includes a circular tube portion and reinforcing ribs evenly distributed around the periphery of the circular tube portion, each of the reinforcing ribs being arranged in a right-angled triangular shape.

[0009] Furthermore, each of the tie bars is provided with guide protrusions evenly distributed around its periphery, each guide protrusion being arranged parallel to the axis of the tie bar, and each of the outer support members is provided with a corresponding guide groove on its inner side.

[0010] Furthermore, both ends of each of the tie bars are designed to be pointed.

[0011] Compared with existing technologies, the advantages of this utility model are:

[0012] 1. The horizontal and vertical mortar joints of each unit stone on the stone wall are symmetrically set with inner grooves and filled with ultra-high performance concrete. At the same time, tie bars are set to improve the overall structural connectivity. By utilizing the advantages of UHP-ECC such as high strength, good durability, wear resistance and good corrosion resistance, the seismic and shear resistance of the stone wall is improved as a whole.

[0013] 2. By setting external supports, the concrete in the first section of the slurry can be squeezed first, thereby promoting the filling of concrete in the horizontal and vertical inner grooves, reducing the occurrence of hollow points and weakening the structural force of the stone wall. At the same time, the solidified concrete, external supports, and tie bars form a strong supporting structure. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example:

[0022] Please see Figure 1-4 A reinforcement structure for a stone wall includes grooves formed on the sides of horizontal mortar joints 3 and vertical mortar joints 4 of any unit stone 2 in the stone wall 1. At least two transverse grooves 5 are symmetrically arranged at the horizontal mortar joints 3 on both sides of any unit stone 2, and at least one vertical groove 6 is symmetrically arranged at the vertical mortar joints on both sides of any unit stone 2. Several tie bars 7 are also provided, each tie bar 7 extending through the mortar layer of the stone wall 1 into the symmetrically arranged transverse grooves 5 or vertical grooves 6. Each transverse groove 5 and vertical groove 6 is filled with ultra-high performance concrete, forming a reinforcement layer 8 after solidification. In this embodiment, ultra-high performance concrete (UHP-ECC) is used. In this embodiment, two transverse grooves 5 are symmetrically arranged at the horizontal mortar joints 3 on both sides of any unit stone 2, and one vertical groove 6 is symmetrically arranged at the vertical mortar joints on both sides of any unit stone 2. The mortar layer of the stone wall 1 in this example is mainly made of traditional clay-mixed mortar, which has low strength.

[0023] Each tie bar 7 has an external support 9 slidably installed at both ends. The external support 9 is inverted cone shape and slides along the tie bar 7 into the horizontal inner groove 5 or the vertical inner groove 6. Each horizontal inner groove 5 and vertical inner groove 6 is filled in two stages. After the first stage of grouting 10, the external support 9 is pressed in until it is submerged, and then the second stage of grouting 11 is performed to fill it. By setting the external support 9, the concrete in the first stage of grouting 10 can be squeezed first, thereby promoting the filling of the concrete in each horizontal inner groove 5 and vertical inner groove 6, reducing the generation of voids and weakening the structural force of the stone wall 1. At the same time, the solidified concrete body, the external support 9 and the tie bar 7 form a strong supporting structure. At the same time, the high strength, good durability, wear resistance and corrosion resistance of UHP-ECC are utilized to improve the overall seismic and shear resistance of the stone wall 1.

[0024] In one embodiment, such as Figure 3 As shown, the outer support member 9 is arranged in the shape of an inverted cone column, and a sliding hole 12 is provided in the middle of the outer support member 9 to slide and connect with the tie bar 7.

[0025] In another embodiment, such as Figure 4As shown, the outer support member 9 includes a circular tube portion 91 and reinforcing ribs 92 evenly distributed around the circular tube portion 91. Each reinforcing rib 92 is arranged in a right-angled triangular shape.

[0026] Furthermore, each tie bar 7 is provided with guide protrusions 13 evenly distributed around its periphery. Each guide protrusion 13 is arranged parallel to the axis of the tie bar 7. Each outer support 9 is provided with a corresponding guide groove 14 on its inner side to facilitate the guiding and sliding of each outer support 9.

[0027] Both ends of each tie bar 7 are pointed, which facilitates the insertion of each tie bar 7 into the wall and the guiding insertion of each external support 9.

[0028] Working principle: On the existing stone wall 1, horizontal grooves 5 and vertical grooves 6 are dug out at the horizontal mortar joints 3 and vertical mortar joints 4 of each unit stone 2. Tie bars 7 are passed through accordingly. The grooves are cleaned and the first section of ultra-high performance concrete is poured. Then, the external support 9 is squeezed into the corresponding horizontal groove 5 or vertical groove 6. Then, the second section of ultra-high performance concrete is poured and the jointing is completed.

[0029] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
