[0001] The utility model relates to the technical field of building construction, in particular to an old house reinforcement device. Background Art

[0002] The factories in the 1960s generally adopted a triangular roof system. Most of the roof beams were made of concrete. However, as time went by, these factories had experienced decades of wind and rain, and the concrete materials gradually showed signs of aging and cracking, which seriously threatened the structural safety of the factories. In order to ensure that these factories could continue to be used safely, necessary reinforcement work had to be carried out.

[0003] Steel tie rod reinforcement is a common and effective option. However, in the actual reinforcement process, when dealing with steel tie rod reinforcement of large span spaces, the steel tie rods in the prior art can only apply prestress at the ends of the steel tie rods. The magnitude of this prestress is often difficult to accurately control. If the prestress is too large, it may cause the steel tie rod to deform too much or break during the stress process; if the prestress is too small, the reinforcement effect of the steel tie rod may not be fully exerted. Utility Model Content

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the defect that the steel tie rod reinforcement method in the prior art cannot adjust the prestress, thereby providing an old house reinforcement device.

[0008] An adjusting device, wherein both ends of the adjusting device are detachably connected to the second end of the first connecting rod and the second end of the second connecting rod respectively; the adjusting device can drive the first connecting rod to move away from or closer to the second connecting rod.

[0009] Preferably, one end of the adjusting device is rotatably connected to the first connecting rod, and the other end of the adjusting device is threadedly connected to the second connecting rod.

[0010] Preferably, the adjusting device is threadedly connected to the first connecting rod, and threads at both ends of the adjusting device are opposite.

[0013] Preferably, a through hole for the support rod to pass through is provided on the fixing plate, and the end of the support rod is a first connector, and the first connector passes through the through hole on the fixing plate and is connected to the roof.

[0014] Preferably, the fixing plate is connected to the roof by fasteners passing through the fixing plate.

[0015] Preferably, the fastener is a bolt.

[0016] Preferably, a plurality of through holes for the support rod to pass through are arranged at intervals on the first connecting rod and the second connecting rod, and a second connector for passing through the through holes is arranged at the end of the support rod.

[0034] The old house reinforcement device provided in this embodiment is used to reinforce old houses with triangular roofs.

[0035] like Figure 1 , Figure 2 , Figure 3As shown, a specific implementation of the old house reinforcement device provided in this embodiment includes: a first connecting rod 1, a second connecting rod 2, a support rod 3 and an adjustment device 4. A reinforcement plate 8 is provided on the concrete beam 9 at the top of the triangular roof, and the reinforcement plate 8 is arranged in the middle position of the two sections of concrete beams 9. The first connecting rod 1 is arranged horizontally, and the first end of the first connecting rod 1 is used to connect with the side wall of the house; the ends of the first connecting rod 1 and the second connecting rod 2 are respectively connected to the side wall of the house through steel gaskets 10. The first end of the second connecting rod 2 is used to connect with the side wall of the house; the second connecting rod 2 is coaxially arranged with the first connecting rod 1, and the adjustment device 4 is arranged between the second connecting rod 2 and the first connecting rod 1, and the first connecting rod 1 is driven away from or close to the second connecting rod 2 by the adjustment device 4, so as to adjust the preload between the first connecting rod 1, the second connecting rod 2 and the side wall of the house. The support rod 3 is arranged vertically, one end of the support rod 3 is connected to the first connecting rod 1 or the second connecting rod 2, and the other end is connected to the roof of the house, so that the support rod 3 can provide a certain support force to the roof, thereby sharing the weight of the roof of the house and extending the service life of the house; the two ends of the adjustment device 4 are detachably connected to the second end of the first connecting rod 1 and the second end of the second connecting rod 2 respectively; the adjustment device 4 can drive the first connecting rod 1 to move away from or close to the second connecting rod 2, so as to adjust the tension between the first connecting rod 1 and the second connecting rod 2 through the adjustment device 4, thereby adjusting the stability and bearing capacity of the entire structure, increasing the bending resistance of the structure, and increasing the safety of the structure. At the same time, the adjustment device 4 can adjust the structure according to actual needs, meet the prestressing requirements under different factory requirements and environmental conditions, and increase the flexibility and adjustability of the structure.

[0036] like Figure 4 As shown, in this embodiment, one end of the adjusting device 4 is rotatably connected to the first connecting rod 1, and the other end of the adjusting device 4 is threadedly connected to the second connecting rod 2. At this time, by rotating the adjusting device 4, while the adjusting device 4 and the first connecting rod 1 rotate, the second connecting rod 2 and the adjusting device 4 move, causing the first connecting rod 1 and the second connecting rod 2 to move closer or farther away, thereby adjusting the prestress. By threading the adjusting device 4 and the second connecting rod 2, the connection strength and stability between the adjusting device 4 and the second connecting rod 2 are higher, and the threaded connection can provide more precise adjustment. In addition, as an alternative embodiment, one end of the adjusting device 4 is threadedly connected to the first connecting rod 1 and rotatably connected to the second connecting rod 2. In addition, as an alternative embodiment, the adjusting device 4 can also be set as a hydraulic device, and the prestress is adjusted by driving the driving end of the hydraulic device.

[0037] like Figure 4As shown, in this embodiment, the adjusting device 4 is threadedly connected to the first connecting rod 1, and the threads at both ends of the adjusting device 4 are opposite. At this time, rotating the adjusting device 4 will simultaneously adjust the first connecting rod 1 and the second connecting rod 2, and the adjustment speed is faster and more efficient. In addition, as an alternative embodiment, the adjusting device 4 can also be threadedly connected only to the second connecting rod 2.

[0038] like Figure 2 As shown, in this embodiment, the support rod 3 is provided with the adjustment device 4, and the support rod 3 is connected to the roof through the adjustment device 4. At this time, the support force of the support rod 3 on the roof can be accurately adjusted through the adjustment device 4, so that the support force can reach the required appropriate level to meet the stability of the roof structure, and can also prevent the roof from collapsing and extend the service life of the roof. Specifically, the adjustment device 4 is arranged in the middle position of the support rod 3, that is, the support rod 3 is divided into two independent sections, and the two ends of the adjustment device 4 are respectively connected to the two sections of the support rod 3, and the two support rods 3 are driven to move closer or farther away from each other, so as to adjust the support force of the support rod 3 on the roof. The two ends of the adjustment device 4 are respectively threadedly connected to the support rod 3, and the threads at the two ends are opposite, so that the two support rods 3 move when the adjustment device 4 is rotated. In addition, as a replaceable embodiment, the adjustment device 4 may not be arranged on the support rod 3.

[0039] like Figure 2 As shown, in this embodiment, a fixing plate 6 is detachably provided on the roof. The fixing plate 6 is an angle steel in the prior art. The angle steel has two long steel strips with two sides perpendicular to each other and an angle, and has a strong load-bearing capacity. One side of the angle steel is attached to the roof, and the other side is detachably connected to the support rod 3. At this time, the support rod 3 can be disassembled more conveniently, which is convenient for replacing or repairing the support rod 3. At the same time, the detachable design can provide greater flexibility, and the layout and position of the support rod 3 can be adjusted according to actual needs. In addition, as a replaceable embodiment, the support rod 3 can be directly connected to the roof by bolts.

[0040] like Figure 2 As shown, in this embodiment, the fixing plate 6 is provided with a through hole for the support rod 3 to pass through, and the end of the support rod 3 has a first connector 7. After the first connector 7 of the support rod 3 passes through the through hole, a part of the first connector 7 is snapped into the through hole, that is, the first connector 7 does not completely pass through the through hole, and a part of the first connector 7 is snapped into the through hole to form a fixation, at which time the support rod 3 and the first connector 7 can be quickly installed and removed. In addition, as an alternative embodiment, the support rod 3 can be fixedly connected to the fixing plate 6. In addition, as an alternative embodiment, the support rod 3 can be connected to the fixing plate 6 by bolts.

[0041] like Figure 2 As shown, in this embodiment, the fixing plate 6 is connected to the roof through a fastener passing through the fixing plate 6, and the fastener is a bolt. The fixing plate 6 is an angle steel, and the bolt passes through the fixing plate 6 to connect with the roof. At this time, the bolt can strengthen the connection strength between the angle steel and the house, and at the same time, it is easier to disassemble the support rod 3, which is convenient for later maintenance. In addition, as an alternative embodiment, the fastener can also be set as a stud.

[0042] like Figure 1 As shown, in this embodiment, a plurality of through holes for the support rod 3 to pass through are arranged at intervals on the first connecting rod 1 and the second connecting rod 2, and a second plug-in piece for passing through the through hole is arranged at the end of the support rod 3, and the second plug-in piece at the end of the support rod 3 is inserted into the through hole to form a support fixation. The support rod 3 can select the through hole at a suitable position for plugging according to actual needs, saving time and labor costs. In addition, as an alternative embodiment, a plurality of through holes can be arranged only on the second connecting rod 2.

[0043] like Figure 2 As shown, in this embodiment, the first connector 7 and the second connector are arc-shaped, that is, the arc-shaped first connector 7 and the second connector are similar to hooks, which can provide a more secure connection after passing through the through hole and the through hole to prevent the support rod 3 from being separated and shaking. In addition, as an alternative embodiment, the first connector 7 and the second connector are cylindrical with a front end diameter smaller than a rear end diameter.

[0044] The installation method of the old house reinforcement device is as follows: Use a reinforcement plate 8 to connect two sections of concrete beams 9 on the top of the triangular roof, where the reinforcement plate 8 is an angle steel. Then, according to the span of the house, select the first connecting rod 1 and the second connecting rod 2 of appropriate length, and install the adjustment device 4 to one-third of the overall length. Figure 5 As shown, a hole is opened on the side wall of the original house, and after the ends of the first connecting rod 1 and the second connecting rod 2 are passed through the house, a gasket 10 is first placed on the ends of the first connecting rod 1 and the second connecting rod 2, and a nut 5 is screwed to the ends of the first connecting rod 1 and the second connecting rod 2 to abut against the gasket 10. The first connecting rod 1 and the second connecting rod 2 are connected by an adjustment device 4, and the two ends of the adjustment device 4 are respectively threadedly connected to the first connecting rod 1 and the second connecting rod 2, and the threads of the two are opposite. The prestress between the first connecting rod 1 and the second connecting rod 2 is adjusted by screwing the adjustment device 4. After adjustment, the vibrating string method is used to measure whether the prestress meets the standard. Among them, one end of the support rod 3 passes through the through hole on the second connecting rod 2, and the other end passes through the through hole on the fixing plate 6, forming a supporting force for the roof, thereby adjusting the stability and bearing capacity of the entire structure, increasing the bending resistance of the structure, and increasing the safety of the structure.

[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the present utility model.
