Description

Technical Field

[0001] The utility model relates to the technical field of building repair, in particular to a temporary supporting device for masonry structure construction. Background Art

[0002] Some modern and contemporary buildings have two or three-story brick-wood or brick-concrete structures. In the renovation of similar buildings, in order to preserve the historical style and meet the requirements of subsequent functional use, the "replacing the guts" approach is sometimes adopted, that is, only the outer wall of the building is retained, and the original internal structure is completely demolished and rebuilt according to the new structural system.

[0003] In the construction of this type of project, after the internal structure is demolished, the height of the retained exterior wall is changed from one floor (3-4m high) to two floors (7-8m). Under this condition, the vertical bearing capacity of the brick wall is generally not a problem, but the height-to-thickness ratio is seriously exceeded, and the horizontal lateral resistance is greatly weakened. In the subsequent construction, if the operation is improper or affected by other horizontal forces (such as wind loads, etc.), the retained exterior wall structure will become unstable.

DETAILED DESCRIPTION

[0038] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0039] like Figure 1-4As shown, this embodiment provides a temporary support device for masonry structure construction, which includes a first support member 200, and the two ends of the first support member 200 can be connected to two oppositely arranged external walls 100. When the original internal structure of the building is completely removed, the two oppositely arranged external walls 100 are connected by the first support member 200, so that the two oppositely arranged external walls 100 can form a whole, which can better improve the stability of the external walls 100.

[0040] Specifically, the two relatively arranged exterior walls 100 can cooperate with each other under the action of the first support member 200. When subjected to force in the horizontal direction, the force can be transferred between the two exterior walls 100 through the first support member 200, thereby offsetting the horizontal force. At the same time, under the connecting action of the first support member 200, the exterior walls 100 in two relatively positioned positions can form a whole, share two supporting points with the ground, and thereby improve the horizontal lateral resistance of the exterior wall 100.

[0041] Furthermore, the number of the first support members 200 can be set to be multiple, and the stability of the connection between the exterior walls 100 can be further improved by connecting two exterior walls 100 that are arranged opposite to each other through multiple first support members 200.

[0042] Furthermore, at least one end of the first support member 200 is connected to the exterior wall 100 via tension bolts. In this embodiment, both ends of the first support member 200 are connected to the corresponding exterior wall 100 via tension bolts as an example. The provision of tension bolts can better realize the connection between the first support member 200 and the exterior wall 100, improve the stability of the connection between the first support member 200 and the exterior wall 100, and thereby enable the first support member 200 to stably connect the two exterior walls 100 in opposite positions.

[0043] In some embodiments, the tension bolt includes a screw portion 300 that is inserted through the exterior wall 100 and a first tensile portion 310 that is disposed on the screw portion 300. During installation, the screw portion 300 is inserted through the exterior wall 100 so that both ends of the screw portion 300 are exposed at both sides of the exterior wall 100, the first tensile portion 310 is located on a side of the exterior wall 100 that is away from the first support member 200, and the screw portion 300 on a side of the exterior wall 100 that is close to the first support member 200 is connected to the first support member 200.

[0044] It can be understood that the two ends of the screw portion 300 passing through the exterior wall 100 are respectively connected to the first tensile portion 310 and the first support member 200. When the exterior wall 100 is subjected to force in the horizontal direction, the first tensile portion 310 and the exterior wall 100 will be squeezed against each other or the first support member 200 and the exterior wall 100 will be squeezed against each other, thereby resisting the exterior wall 100 and offsetting the force applied to the exterior wall 100 in the horizontal direction, thereby maintaining the stability of the exterior wall 100 in the horizontal direction.

[0045] In some embodiments, the first tensile portion 310 includes a first baffle 311 sleeved on the screw portion 300 and a first nut 312 threadedly connected to the screw portion 300; specifically, a first through hole 313 is provided on the first baffle 311, and the first baffle 311 is sleeved on the screw portion 300 through the first through hole 313. It can be understood that the positions of the first baffle 311 and the first nut 312 on the screw portion 300 are both movable.

[0046] During installation, first, the screw portion 300 is passed through the exterior wall 100, and then the first baffle 311 is sleeved on the screw portion 300 through the first through hole 313 on the side of the exterior wall 100 away from the first support member 200, and the first nut 312 is threadedly connected to the screw portion 300, and then the screw portion 300 on the side of the exterior wall 100 close to the first support member 200 is connected to the first support member 200, and then the first nut 312 is operated so that the first nut 312 drives the first baffle 311 to be pressed against the exterior wall 100. It can be known that, under the action of the first nut 312, the position of the first baffle 311 on the screw part 300 can be adjusted, which is convenient for disassembly and assembly, and in the installed state, when the exterior wall 100 is subjected to force in the horizontal direction, the exterior wall 100 can be squeezed with the first baffle 311, so that the first baffle 311 can resist the exterior wall 100, and then offset the horizontal force exerted on the exterior wall 100, thereby improving the horizontal stability of the exterior wall 100.

[0047] In some embodiments, the first tensile part 310 includes a first wood square 314, and a second through hole 315 is provided on the first wood square 314, and the first wood square 314 can be sleeved on the screw part 300 through the second through hole 315. Specifically, during the installation process, after the screw part 300 is inserted into the exterior wall 100, the first wood square 314 is sleeved on the screw part 300 through the second through hole 315, and then the first baffle 311 is sleeved on the screw part 300 through the first through hole 313, and then the first nut 312 is threadedly connected to the screw part 300; the screw part 300 at the side of the exterior wall 100 close to the first support member 200 is connected to the first support member 200, and then the first nut 312 is operated so that the first nut 312 drives the first baffle 311 to push the first wood square 314 to be pressed against the exterior wall 100.

[0048] In particular, in the installed state, the first wooden square 314 is located between the first baffle 311 and the outer wall 100, that is, when the outer wall 100 is subjected to force in the horizontal direction, the first wooden square 314 directly plays a role of resisting the outer wall 100; since the first wooden square 314 is made of wood material, the outer wall 100 will not be scratched or damaged during the process of mutual squeezing between the first wooden square 314 and the outer wall 100, and a certain protective effect is played on the appearance of the outer wall 100.

[0049] Furthermore, the first wooden square 314 made of wooden material itself also has a certain deformation function, which can better buffer the horizontal force exerted on the outer wall 100 and more effectively maintain the stability of the outer wall 100 in the horizontal direction.

[0050] In some embodiments, the tension bolt includes a second tensile portion 320 disposed on the screw portion 300. During installation, the screw portion 300 is inserted into the exterior wall 100 so that both ends of the screw portion 300 are exposed at both sides of the exterior wall 100, the first tensile portion 310 is located on the side of the exterior wall 100 away from the first support member 200, and the second tensile portion 320 is located on the side of the exterior wall 100 close to the first support member 200, and the second tensile portion 320 is connected to the first support member 200 to complete the installation.

[0051] When the exterior wall 100 is subjected to force in the horizontal direction, the first tensile portion 310 and the exterior wall 100 will be squeezed against each other, or the first support member 200 and the exterior wall 100 will be squeezed against each other through the second tensile portion 320, thereby resisting the exterior wall 100 and offsetting the force applied to the exterior wall 100 in the horizontal direction, thereby maintaining the stability of the exterior wall 100 in the horizontal direction.

[0052] In some embodiments, the second tensile portion 320 includes a second baffle plate 321 sleeved on the screw portion 300 and a second nut 322 threadedly connected to the screw portion 300; specifically, a third through hole 323 is provided on the second baffle plate 321, and the second baffle plate 321 is sleeved on the screw portion 300 through the third through hole 323. It can be understood that the positions of the second baffle plate 321 and the second nut 322 on the screw portion 300 are both movable.

[0053] During installation, first, the screw portion 300 is inserted into the exterior wall 100, and then the first baffle 311 is sleeved onto the screw portion 300 through the first through hole 313 at the side of the exterior wall 100 away from the first support member 200, and the first nut 312 is threadedly connected to the screw portion 300, and then the second baffle 321 is sleeved onto the screw portion 300 through the third through hole 323 at the side of the exterior wall 100 close to the first support member 200, and the second nut 322 is threadedly connected to the screw portion 300, and then the second baffle 321 is connected to the first support member 200, and then the first nut 312 and the second nut 322 are operated, so that the first nut 312 drives the first baffle 311 and the first wooden square 314 to be pressed against the exterior wall 100, and the second nut 322 drives the second baffle 321 to be pressed against the exterior wall 100. It can be known that, under the action of the second nut 322, the position of the second baffle 321 on the screw portion 300 can be adjusted, which is convenient for disassembly and assembly, and in the installed state, when the exterior wall 100 is subjected to force in the horizontal direction, the exterior wall 100 can be squeezed with the second baffle 321, so that the second baffle 321 can resist the exterior wall 100, and then offset the horizontal force exerted on the exterior wall 100, thereby improving the horizontal stability of the exterior wall 100.

[0054] It should be noted that the second baffle 321 and the first support member 200 can be connected by welding or bolting, so that the first support member 200 can be connected to the outer wall 100 through the second baffle 321 and the screw part 300 .

[0055] In some embodiments, the second tensile part 320 includes a second wood square 324, and a fourth through hole 325 is provided on the second wood square 324, so that the second wood square 324 can be sleeved on the screw part 300 through the fourth through hole 325. Specifically, during the installation process, after the screw part 300 is inserted into the exterior wall 100, the second wood square 324 is sleeved on the screw part 300 through the fourth through hole 325, and then the second baffle 321 is sleeved on the screw part 300 through the third through hole 323 and connected to the first support member 200, and then the second nut 322 is threadedly connected to the screw part 300, and then the second nut 322 is operated so that the second nut 322 drives the second baffle 321 to push the second wood square 324 to be pressed against the exterior wall 100.

[0056] In particular, in the installed state, the second wooden square 324 is located between the second baffle 321 and the outer wall 100, that is, when the outer wall 100 is subjected to force in the horizontal direction, the second wooden square 324 directly plays a role of resisting the outer wall 100; since the second wooden square 324 is made of wood material, the outer wall 100 will not be scratched or damaged during the process of mutual squeezing between the second wooden square 324 and the outer wall 100, and a certain protective effect is played on the appearance of the outer wall 100.

[0057] Furthermore, the second wooden beam 324 made of wood material itself also has a certain deformation function, which can better buffer the horizontal force exerted on the outer wall 100 and more effectively maintain the stability of the outer wall 100 in the horizontal direction.

[0058] In some embodiments, the first support member 200 for connecting two external walls 100 disposed at opposite positions is maintained perpendicular to the corresponding two external walls 100. Further, in this embodiment, the two external walls 100 disposed at opposite positions are in a vertical state as a whole, and the first support member 200 connecting the two external walls 100 is in a horizontal state as a whole. When the two external walls 100 are subjected to force in the horizontal direction, the first support member 200 can better resist the external walls 100 in the horizontal direction, thereby offsetting the force applied to the external walls 100 in the horizontal direction.

[0059] Combination Figure 3 As shown, in some embodiments, the temporary supporting device further includes a second supporting member 400 connected to the first supporting member 200, wherein the second supporting member 400 is fixedly installed on the ground or on the floor.

[0060] It is understandable that the second support member 400 can support the first support member 200, further improve the stability of the first support member 200, and further improve the stability of the exterior wall 100 connected to the first support member 200. The first support member 200 and the second support member 400 can be fixed by welding, bolting, etc.

[0061] Of course, in another preferred embodiment of the present application, when the first support member 200 is only used to connect one exterior wall 100 , the second support member 400 can be regarded as another exterior wall 100 opposite to the exterior wall 100 to facilitate the use of the first support member 200 .

[0062] In some embodiments, the second support member 400 is disposed parallel to the outer wall 100 , and the second support member 400 can better assist the first support member 200 in supporting the outer wall 100 , so as to improve the stability of the outer wall 100 in the horizontal direction.

[0063] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
