Description

Technical Field

[0001] The utility model relates to the technical field of diaolou reinforcement, and particularly to a prefabricated prestressed light steel frame diaolou reinforcement structure. Background Technique

[0002] There are a large number of existing Tibetan and Qiang diaolous in China, and they have a long history. As a plateau heritage, the unique value of diaolous in history, culture and architecture has gradually been affirmed and recognized by people. The diaolou is not only a precious cultural heritage but also an important part of the local unique culture. For a long time, due to the influence of natural disasters such as earthquakes, debris flows, and wind disasters, as well as human destruction and other factors, most diaolous have overall inclinations and are extremely prone to overall collapse caused by local damage.

[0003] Chinese Patent Application No. CN202121954579.7 discloses a diaolou stone masonry wall reinforcement device, including a pick saw, a steel mesh, and a polymer sand layer. One or more of anchor bars, short bars, or tie bars implanted into the wall are also provided around the steel mesh. This method can effectively repair damaged parts, improve the bearing capacity and ductility of the wall, and improve the ability to resist damage without destroying the integrity of the original wall and the external facade style. Although this method locally reinforces the diaolou wall, it is insufficient in improving the overall performance of the diaolou. For diaolous that have already tilted, this existing technology is difficult to handle.

[0004] Chinese Patent Application No. CN2410413913.6 discloses a method for overall seismic reinforcement of masonry ancient pagodas, including several reinforcement rods, and hoops are arranged inside and outside each layer of the tower body. All the hoops outside the tower body are connected to the reinforcement rods. This method requires drilling holes in the inner and outer walls of the diaolou. However, due to the irregular stones and relatively thick walls that make up the diaolou, the operation difficulty is relatively large. Therefore, the number of drilling holes should be reduced as much as possible, and this method will damage the integrity of the blocks and does not meet the basic reinforcement principles of ancient buildings, so the practicability of this scheme cannot be fully guaranteed.

[0005] Therefore, there is an urgent need for a new type of prefabricated reinforcement structure that meets the basic reinforcement principles of "minimum intervention, reversibility, and identifiability" for the repair of ancient buildings, efficiently improves the reliability of diaolou reinforcement, and enables it to be preserved for a longer time. Content of the Utility Model

[0006] The purpose of the utility model is to provide a prefabricated prestressed light steel frame diaolou reinforcement structure, which can be installed inside the diaolou to limit the overall deformation of the tower structure, prevent the diaolou from twisting or tilting and collapsing during an earthquake, and reduce the intervention on the diaolou while ensuring the reinforcement effect of the diaolou.

[0007] To achieve the object of the present utility model, the technical solution adopted is: a prefabricated prestressed light steel frame turret reinforcement structure, including a plurality of H-shaped steel columns arranged at intervals along the inner wall of the turret, an H-shaped steel beam is horizontally connected between two adjacent H-shaped steel columns, a lateral tension rod assembly is obliquely connected, and an adjustable tension cable assembly is also obliquely connected between two diagonally opposite H-shaped steel columns.

[0008] Further, a steel backing plate is fixed at the lower end of the H-shaped steel column.

[0009] Further, a lower foundation for fixing on the ground is also installed at the lower end of the H-shaped steel column.

[0010] Further, the lower foundation includes a bearing platform fixed at the lower end of the H-shaped steel column, and a plurality of ground screw steel pipe piles implanted underground are installed on the bearing platform.

[0011] Further, the plurality of H-shaped steel columns are respectively installed at the inner corners of the turret.

[0012] Further, angle steels for connecting with the H-shaped steel column are installed at both ends of the H-shaped steel beam.

[0013] Further, a plurality of transverse stiffeners are connected between the two flange plates of the H-shaped steel beam.

[0014] Further, there are at least two H-shaped steel beams between two adjacent H-shaped steel columns, and the plurality of H-shaped steel beams are arranged at intervals along the height direction of the H-shaped steel column.

[0015] Further, the lateral tension rod assembly includes a lateral tension rod obliquely connected between adjacent H-shaped steel columns.

[0016] Further, the adjustable tension cable assembly includes double hook head steel wires respectively fixed on two diagonally opposite H-shaped steel columns, and a turnbuckle is connected between the two double hook head steel wires.

[0017] The beneficial effects of the present utility model are:

[0018] In this utility model, an H-shaped steel column, an H-shaped steel beam and a lateral tie rod assembly jointly form a steel frame, which can be installed inside the watchtower to limit the overall deformation of the tower body and prevent the watchtower from collapsing due to torsion and tilting during an earthquake; by adding an inclined adjustment cable assembly between two diagonally opposite H-shaped steel columns, the prestress of the steel frame can be adjusted in real time by using the turnbuckle in it; by adding the H-shaped steel beam and the lateral tie rod assembly, the stability of the steel frame is further improved; by adding ground screw steel pipe piles, strong end constraints are provided for the reinforcement structure, the construction is fast, the reinforcement period is shortened, the disturbance to the foundation is reduced, and the compaction of the foundation is realized at the same time. By adding the prestressed light steel frame provided by this utility model inside the watchtower, while ensuring the reinforcement effect of the watchtower, the intervention on the watchtower body is also reduced, meeting the basic principles of "minimum intervention, reversibility and identifiability" for the reinforcement of ancient buildings.

[0038] The following further elaborates on the present utility model in conjunction with the drawings and the implementation mode. It can be understood that the specific implementation mode described herein is only used to explain the relevant content and does not limit the present utility model. Additionally, it should be noted that for the convenience of description, only the parts related to the present utility model are shown in the drawings.

[0039] It should be noted that, without conflict, the implementation modes and features in the implementation modes of the present utility model can be combined with each other. The following will detail the present utility model with reference to the drawings and in conjunction with the implementation modes.

[0040] As Figures 1 to 8 shown, a prefabricated prestressed light steel frame blockhouse reinforcement structure provided by the present utility model includes four H-shaped steel columns 2, which are respectively installed at the four inner corners of the blockhouse 6. An H-shaped steel beam 3 and a lateral tie rod assembly 4 are connected between adjacent two H-shaped steel columns. When the H-shaped steel beam 3 is installed, the H-shaped steel beam 3 remains horizontal, while when the lateral tie rod assembly 4 is installed, one end of the lateral tie rod assembly 4 is fixed to the upper end of one of the H-shaped steel columns 2, and the other end of the lateral tie rod assembly 4 is fixed to the lower end of another H-shaped steel column 2. The steel frame is jointly composed of the H-shaped steel columns 2, the H-shaped steel beams 3, and the lateral tie rod assembly 4. The four faces of the steel frame respectively restrict the four inner walls of the blockhouse 6, thereby preventing the blockhouse 6 from twisting and tilting and collapsing during an earthquake.

[0041] There is also an inclined adjustment cable assembly 5 connected between two H-shaped steel columns 2 located inside the diagonal corner of the watchtower 6. One end of the inclined adjustment cable assembly 5 is fixed to the upper end of one of the H-shaped steel columns 2, and the other end of the inclined adjustment cable assembly 5 is fixed to the lower end of the other H-shaped steel column 2. Moreover, the tension degree of the inclined adjustment cable assembly 5 can be adjusted during installation. Since there are four H-shaped steel columns 2 in this embodiment and two inclined adjustment cable assemblies 5, one inclined adjustment cable assembly 5 is connected between two diagonally arranged H-shaped steel columns 2, and the other inclined adjustment cable assembly 5 is connected between the other two diagonally arranged H-shaped steel columns 2. By adjusting the tension degree of the inclined adjustment cable assembly 5 and cooperating with the H-shaped steel beam 3 and the lateral tension rod assembly 4, the stability of the steel frame is further improved.

[0042] When this utility model is used for internal reinforcement of the Tibetan and Qiang watchtower 6, first, four lower bases 1 are installed at the four inner corners of the watchtower 6, then four H-shaped steel columns 2 are fixedly installed on the lower bases 1, and then the H-shaped steel beam 3 and the lateral tension rod assembly 4 are used to laterally reinforce between the H-shaped steel columns 2 to further improve the stability of the steel frame. Then, the inclined adjustment cable assembly 5 is used to movably connect two groups of H-shaped steel columns 2 arranged diagonally, prestress can be applied, and real-time adjustment can be achieved to improve the reinforcement effect of the watchtower 6.

[0043] As Figure 3 shown, the H-shaped steel column 2 extends along the height direction of the watchtower 6, and a steel backing plate 202 is fixed to the lower end of the H-shaped steel column 2, which facilitates the connection between the H-shaped steel column 2 and the lower base 1.

[0044] A lower base 1 is also installed at the lower end of the steel backing plate 202 in the H-shaped steel column 2. During the installation of this utility model, the lower base 1 is used to fix the H-shaped steel column 2 to the ground to ensure the stability of the steel frame after it is installed in the watchtower 6. Since the H-shaped steel columns 2 are respectively located at the four inner wall corners of the watchtower 6 during installation, when the steel frame is installed, the four lower bases 1 are respectively installed on the ground at the four inner wall corners of the watchtower 6.

[0045] As Figure 2As shown in the figure, the lower foundation 1 includes a bearing platform 101. The bearing platform 101 is fixed to the steel backing plate 202 by bolts. When the present utility model is installed, the bearing platform 101 is attached to the ground at the four inner corners of the watchtower 6. At the same time, a plurality of ground screw steel pipe piles 103 are provided on the bearing platform 101. When the present utility model is installed, the ground screw steel pipe piles 103 are implanted into the ground, thereby fixing the bearing platform 101 to the ground at the four inner corners of the watchtower 6. In order to ensure the installation and disassembly between the ground screw steel pipe piles 103 and the bearing platform 101, a lower fixed flange 102 can be welded and fixed to the top of the ground screw steel pipe piles 103, and bolt holes are reserved on the bearing platform 101. When the ground screw steel pipe piles 103 need to be installed, the lower fixed flange 102 can be directly fixed to the bearing platform 101 by bolts. During the transportation process, the bolts can be loosened and the lower fixed flange 102 can be removed from the bearing platform 101.

[0046] In the present utility model, the bearing platform 101 and the steel backing plate 202 can both be rectangular, and the size of the steel backing plate 202 can be smaller than that of the bearing platform 101. At the same time, the number of ground screw steel pipe piles 103 on the bearing platform 101 can be four or six, and the plurality of ground screw steel pipe piles 103 are symmetrically arranged on the bearing platform 101. Through the H-shaped steel column 2 as the corner support of the steel frame, the steel backing plate 202 is attached to the bearing platform 101, and then bolts are driven into the bolt holes reserved on the bearing platform 101 through the steel backing plate 202 to realize the installation and disassembly between the H-shaped steel column 2 and the lower foundation 1.

[0047] As Figure 5 As shown in the figure, angle steels 302 are fixed to both ends of the two flange plates of the H-shaped steel beam 3 by bolts, and the angle steels 302 are fixed to the H-shaped steel column 2 by bolts. The H-shaped steel beam 3 is used to connect and fix the adjacent two H-shaped steel columns 2, so as to further fix the position of the H-shaped steel column 2 and improve the force stability of the H-shaped steel column 2. In order to improve the support of the angle steel 302 and the connection stability between the H-shaped steel column 2 and the H-shaped cross beam, a triangular reinforcing member 303 is also welded to the angle steel 302. Specifically, the two right-angled sides of the triangular reinforcing member 303 are respectively welded and fixed to the two plates in the angle steel 302.

[0048] In order to ensure the strength of the H-shaped steel beam 3, a plurality of transverse stiffeners 304 are connected between the two flange plates of the H-shaped steel beam 3. One side of the transverse stiffener is simultaneously fixed to the web of the H-shaped steel beam 3, and the plurality of transverse stiffeners are evenly spaced along the axial direction of the H-shaped steel beam 3, thereby further improving the support of the H-shaped cross beam.

[0049] In order to ensure the stability between the adjacent two H-shaped steel columns 2, the number of H-shaped steel beams 3 connecting the adjacent two H-shaped steel columns 2 is not less than two, and the plurality of H-shaped steel beams 3 are spaced along the height direction of the H-shaped steel column 2.

[0050] As shown Figure 6 in the figure, the lateral tie rod fixing assembly 4 includes a lateral tie rod 403. When the lateral tie rod 403 is installed, in two adjacent H-shaped steel columns 2, connecting plate groups 401 are fixed to the upper end of one H-shaped steel column 2 and the lower end of the other H-shaped steel column 2, and high-strength bolts 402 are installed on the connecting plate groups 401. The end of the lateral tie rod 403 is sleeved on the high-strength bolt 402. It should be noted here that in order to make the end of the lateral tie rod 403 as close as possible to the right angle where the H-shaped steel beam 3 is connected to the H-shaped steel column 2 during installation, therefore, the two connecting plate groups 401 for installing the high-strength bolts 402 can be directly fixed to the angle steel 302 for fixing the H-shaped steel beam 3 during installation; by arranging the connecting plate groups 401 on two adjacent H-shaped steel columns 2 and fixing the lateral tie rod 403 with high-strength bolts 402, the connection stability between the lateral tie rod 403 and the H-shaped steel column 2 is further increased, and it also plays a role in mutually reinforcing and stabilizing the H-shaped steel beam 3.

[0051] When there are two or more H-shaped steel beams 3 between two adjacent H-shaped steel columns 2, a rectangular frame structure is formed under each H-shaped steel beam 3. At this time, the number of lateral tie rods 403 between two adjacent H-shaped steel columns 2 is equal to the number of H-shaped steel beams 3 between two adjacent H-shaped steel columns 2. One lateral tie rod 403 is located between the H-shaped steel column 2, and the remaining lateral tie rods 403 are all located between two adjacent H-shaped steel beams 3 between two adjacent H-shaped steel columns 2. That is, after the H-shaped steel beam 3 is connected between two adjacent H-shaped steel columns 2, multiple rectangular frames are formed between two adjacent H-shaped steel columns 2, and the two ends of the lateral tie rod 403 are respectively connected between two diagonals of the rectangular frame. When there are multiple lateral tie rods 403 between two adjacent H-shaped steel columns 2, the inclination directions of two adjacent lateral tie rods 403 between two adjacent H-shaped steel columns 2 are opposite.

[0052] As shown Figure 4As shown, the diagonal adjustment cable assembly 5 includes a turnbuckle and two double-hook steel wires 501. During installation, in two obliquely opposite H-shaped steel columns 2, lugs are installed at the upper end of one H-shaped steel column 2 and the lower end of the other H-shaped steel column 2. Both ends of the double-hook steel wire 501 have hooks. The two double-hook steel wires 501 are respectively hung on the lugs at the upper end of one H-shaped steel column 2 and the lugs at the lower end of the other H-shaped steel column 2, and the inner ends of the two double-hook steel wires 501 are respectively movably hooked to both ends of the turnbuckle. That is, the diagonal adjustment cable assembly 5 is in an inclined state after being connected to the two obliquely opposite H-shaped steel columns 2. It should be noted here that the turnbuckle includes a positioning ring plate 503, and adjustment screws 502 are threadedly installed at both ends of the positioning ring plate 503. By rotating the adjustment screws 502, the two adjustment screws 502 approach or move away from each other on the positioning ring plate 503, so that the overall length of the turnbuckle changes. By adjusting the turnbuckle, the double-hook steel wire 501 can be driven to generate prestress on the H-shaped steel column 2, and the prestress can be adjusted in real time. The inclined setting of the diagonal adjustment cable assembly 5 can adjust the force direction of the steel frame when adjusting the prestress.

[0053] In the utility model, a steel frame composed of H-shaped steel beams 3 and H-shaped steel columns 2 is arranged inside the watchtower 6 to restrict the overall displacement of the tower body from the inside of the watchtower 6, prevent the watchtower 6 from twisting or tilting and collapsing during an earthquake. By adding a diagonal adjustment cable assembly 5 between the H-shaped steel columns 2, the prestress of the steel frame can be adjusted in real time by using the turnbuckle therein. By adding H-shaped steel beams 3 and lateral tie rod assemblies 4 to the steel frame, the stability of the steel frame is further improved. The prestressed light steel frame added inside the watchtower 6 reduces the interference with the watchtower 6 while ensuring the reinforcement effect of the watchtower 6.

[0054] In addition, since the internal space of the watchtower 6 is relatively narrow and large-scale equipment cannot be used for reinforcement inside like modern buildings, it is more reasonable and convenient to adopt the assembled prestressed light steel frame watchtower reinforcement structure provided by the utility model, and the later maintenance is also more convenient.

[0055] In the present utility model, when the shape of the watchtower 6 changes, the shape of the assembled prestressed light steel frame watchtower reinforcement structure can also be adjusted adaptively. For example, when the inside of the watchtower 6 is pentagonal, there are five lower bases 1 and H-shaped steel columns 2. The five lower bases 1 and H-shaped steel columns 2 are respectively arranged at the five inner corners of the watchtower 6. At this time, the arrangement of the H-shaped steel beams 3 and the lateral tie rod assemblies 4 between two adjacent H-shaped steel columns 2 remains unchanged, while the diagonal adjustment cable assemblies 5 can be connected between any two diagonally opposite H-shaped steel columns 2. At the same time, when designing the present utility model, three unequal lower bases 1 and H-shaped steel columns 2 can also correspond to each wall of the watchtower 6. At this time, when installing the multiple lower bases 1 and H-shaped steel columns 2 corresponding to each wall, two of the lower bases 1 and H-shaped steel columns 2 are installed at the corners of the watchtower 6, and the other lower bases 1 and H-shaped steel columns 2 are arranged at intervals along the width direction of each wall of the watchtower 6. The arrangement of the H-shaped steel beams 3 and the lateral tie rod assemblies 4 between two adjacent H-shaped steel columns 2 remains unchanged, while the diagonal adjustment cable assemblies 5 can be connected between any two diagonally opposite H-shaped steel columns 2.
