Description

Technical Field

[0001] The present invention relates to an assembled vibration-damping enclosure column with lateral supports, which mainly realizes the effect of vibration damping and energy dissipation while ensuring the enhancement of the lateral support capacity of the enclosure by setting lateral supports and polyurethane-coated bolts, so as to protect the enclosure from being damaged by disasters such as strong winds or earthquakes during operation, and belongs to the technical field of structural disaster prevention and mitigation and new construction technologies. Background Art

[0002] Building construction refers to the production activities in the implementation stage of engineering construction and is the construction process of various buildings. In the construction process, in order to create a safe and orderly construction environment, corresponding enclosure structures are needed to isolate the construction site from the external environment. However, for the current enclosure structures, when they are used for protecting construction sites, since they are mostly installed by direct splicing, welding or making cement bases and other fixed connection methods, when they are moved on the construction site, the corresponding enclosures need to be forcibly removed one by one before they can be used. Therefore, there are limitations in installation and removal, the construction efficiency is low, and the reuse of enclosure components is not ideal. In addition, the installed enclosure structure lacks sufficient lateral support capacity and is easily damaged by dynamic actions such as wind loads and earthquakes, affecting the normal construction of the construction site.

[0003] At present, the application of assembled components in the building construction process is in the ascendant, and the characteristics of high construction efficiency, low cost, energy conservation and environmental protection of assembled components are becoming increasingly prominent. Among them, the triangular support component is an assembled component with reinforcement ability, which has the characteristics of large overall stiffness, relatively large bearing capacity and low cost. Its unique structural form can effectively connect horizontal and vertical forces and transfer forces, thereby achieving the purpose of strengthening the structural performance.

[0004] In addition, the structural energy dissipation and vibration damping technology has also been gradually applied to the building construction process. Energy dissipation devices are set at some parts of the structure. Before the main body enters the inelastic state, the device takes the lead in entering the energy dissipation working state, and dissipates energy through the elastic-plastic hysteretic deformation such as friction, bending, shear or torsion generated by the device to reduce the dynamic response of the main structure, ensuring construction safety. However, at present, the energy dissipation and vibration damping technology for the normal use of structures at home and abroad is relatively mature, while the technologies, materials and processes for structural vibration damping and disaster prevention and mitigation during the construction process all urgently need in-depth research and development.

[0005] Existing research shows that polyurethane rubber (UR) is a good vibration-damping and energy-dissipating material with excellent wear resistance. Laboratory test results show that the wear resistance of UR is 3 to 5 times that of natural rubber and can often be as high as about 10 times in practical applications. It has high strength and good elasticity within the Shore A60 to Shore A70 hardness range. The UR vibration-damping element can absorb 10% to 20% of the vibration energy, and the higher the vibration frequency, the greater the energy absorption. Therefore, it is suitable for use in structural vibration damping.

[0006] To better solve the problems existing in current construction site enclosures, referring to the above-mentioned advanced technical ideas, the present invention proposes an assembled vibration-damping enclosure column with lateral supports to significantly enhance the lateral support capacity of the enclosure structure, improve the structural construction efficiency, and effectively alleviate the damage to the enclosure structure caused by dynamic actions such as wind loads. Summary of the Invention

[0007] To improve the lateral support capacity and structural construction efficiency of the enclosure structure, and to alleviate the damage to the enclosure structure caused by dynamic actions such as wind loads, the present invention provides an assembled vibration-damping enclosure column with lateral supports. The present invention mainly consists of devices such as an inner column, an outer column, a lateral support main board, a lateral support bottom board, a longitudinal support main board, a longitudinal support bottom board, and polyurethane-coated bolts. Compared with traditional enclosure columns, the equipped lateral supports make the enclosure more stable. The adopted inner and outer double-column structure enables the enclosure column to have a height-adjustable function. Using polyurethane-coated bolts to connect the lateral support and the column main body endows the enclosure column with excellent vibration-damping and energy-dissipating capabilities. The components of the enclosure column are connected by bolts, and the folding and unfolding of the enclosure support can be achieved by adjusting the positions of a few bolts, significantly improving the construction efficiency of the enclosure structure.

[0008] The technical solution adopted by the present invention is an assembled vibration-damping enclosure column with lateral supports. The design of its lateral support refers to a triangular support member, and the main board of the lateral support has a diagonal brace similar to that of a triangular support member. The fastening bolts on the lateral support bottom board fix the bottom board to the ground, and the main board serves as a diagonal brace to connect the outer column and the bottom board. When the side is subjected to wind loads or other dynamic actions, the baffle transfers the acting force to the enclosure column. The lateral support main board of the column is stressed and transfers the acting force to the bottom board, and then transfers the acting force to the ground. Compared with the resistance of the base of a traditional enclosure column, the resistance arm of the fastening bolts on the bottom board is larger, and the lateral bearing capacity of the enclosure column is also larger. The fastening bolts on the lateral support bottom board cooperate with the lateral support main board to fix the enclosure column to the ground, avoiding the production of a cement base. Additionally, in locations where it is not convenient to install fastening bolts, the enclosure can also be fixed by placing heavy objects such as sandbags and stones on the lateral support bottom board.

[0009] An assembled vibration-damping enclosure column with lateral supports, and its main devices include: an inner column (1), an outer column (2), an adjustment bolt (3), an adjustment bolt hole (4), a longitudinal support main board (5), a longitudinal support bottom board (6), a longitudinal support rotating bolt (7), a longitudinal support bolt (8), a longitudinal support storage bolt hole (9), a lateral support main board (10), a lateral support bottom board (11), a lateral support rotating bolt (12), a fastening bolt (13), a polyurethane-coated bolt (14), a lateral support storage bolt hole (15), a longitudinal support bolt hole (16), and a lateral support bolt hole (17). It is characterized in that: the inner column (1) and the outer column (2) are connected by inserting the adjustment bolt (3) into the adjustment bolt hole (4) to form the main structure of the enclosure column. The longitudinal support main board (5) and the longitudinal support bottom board (6) form a longitudinal support, and the two are hinged by the longitudinal support rotating bolt (7). The longitudinal support participates in transmitting the force on the baffle (22) to the enclosure column and controls it from deflecting. The lateral support main board (10) and the lateral support bottom board (11) form a lateral support, and the two are hinged by the lateral support rotating bolt (12). The longitudinal support bolt (8) passes through both ends of the longitudinal support and is inserted into the longitudinal support bolt hole (16) or the longitudinal support storage bolt hole (9) to connect the longitudinal support to the outer column (2); the polyurethane-coated bolt (14) passes through both ends of the lateral support and is inserted into the lateral support bolt hole (17) or the lateral support storage bolt hole (15) to connect the lateral support to the outer column (2). The fastening bolt (13) passes through the fastening bolt hole (21) on the lateral support bottom board (6) to fix the lateral support on the ground. The lateral support transmits the force from the enclosure column to the ground to ensure the lateral stability of the enclosure. The baffle (22) is placed in the gap of the unfolded longitudinal support, and the longitudinal support bolt (8) is used to pass through the longitudinal support storage bolt hole (9) to fix the baffle.

[0010] The described assembled vibration-damping enclosure column with lateral supports is characterized in that: its lateral support main board (10) is connected to the outer column and the bottom board as a diagonal brace. When bearing dynamic actions such as wind loads, the baffle (22) transmits the force to the enclosure column. The lateral support main board (10) of the column is stressed and transmits the force to the bottom board, and then transmits the force to the ground. Due to the large resistance arm of the fastening bolt (13) on the bottom board, the enclosure column has sufficient lateral bearing capacity.

[0011] The described prefabricated vibration damping enclosure column with lateral support is characterized in that its longitudinal support and lateral support are unfolded and folded by moving in the vertical plane. When unfolding, the longitudinal support bolt (8) and the polyurethane-coated bolt (14) are respectively moved from the longitudinal support storage bolt holes (9) and the lateral support storage bolt holes (15) to the longitudinal support bolt holes (16) and the lateral support bolt holes (17) at the upper part of the outer column (2). When folding, the longitudinal support bolt (8) and the polyurethane-coated bolt (14) are respectively moved back to the longitudinal support storage bolt holes (9) and the lateral support storage bolt holes (15). By only changing the positions of 2 polyurethane-coated bolts (14) and 4 longitudinal support bolts (8), the unfolding and folding of the column can be completed, effectively improving the construction efficiency and service life of the column.

[0012] The described prefabricated vibration damping enclosure column with lateral support is characterized in that its column body mainly consists of two parts: an inner column (1) and an outer column (2). The length of the outer column (2) is not less than 1.8 m, and the cross-sectional area is not less than 50 cm 2 , the inner column (1) is slightly shorter than the outer column (2), with a length not less than 65% of the outer column length, and the cross-sectional area is slightly smaller, with an area not less than 80% of the outer column area, so that the inner column (1) can be nested in the outer column (2). The inner column (1) and the outer column (2) are connected by adjustment bolts (3). There are multiple evenly distributed and identically sized adjustment bolt holes (4) at the lower part of the inner column (1) and the upper part of the outer column (2). The height of the enclosure column can be changed by selectively installing the adjustment bolts (3) into two of the bolt holes.

[0013] The described prefabricated vibration damping enclosure column with lateral support is characterized in that its polyurethane-coated bolts (14) are used to connect the outer column (2) with the lateral support main board (10) and the lateral support bottom board (11) respectively. On the premise that the lateral support bottom board (11) is firmly connected to the ground, when the enclosure is stressed and the enclosure column has a tendency to twist, the polyurethane coating (18) in the polyurethane-coated bolts (14) will play an energy-dissipating role, generating elastoplastic deformation to absorb part of the energy and achieving the effect of vibration damping and energy dissipation.

[0014] The described prefabricated vibration damping enclosure column with lateral support is characterized in that the polyurethane-coated bolt (14) mainly consists of a polyurethane coating (18), a nut (19) of the polyurethane-coated bolt, and a screw (20) of the polyurethane-coated bolt. The material of the polyurethane coating is polyurethane rubber (UR), and the hardness is not less than Shore A60. The polyurethane coating (18) is wrapped around the screw (20) of the polyurethane-coated bolt, and the nuts (19) on both sides of the polyurethane-coated bolt fix the polyurethane coating (18) to keep its relative position unchanged between the lateral support main board (10) and the lateral support bolt hole (17), playing its role of vibration damping and energy dissipation.

[0015] For the prefabricated shock-absorbing enclosure column with lateral support described above, it is characterized in that: the length of the extended part of the cross-section of the inner column (1) and the outer column (2) except for the core rectangle is not less than 5 cm, and the width is not less than 1.5 cm, which is convenient for arranging bolt holes. The outer diameter of the polyurethane rubber coating is not less than 2 cm, and the length is more than twice the width of the lateral support main board, ensuring the good working performance of the polyurethane rubber coating bolts.

[0016] For the prefabricated shock-absorbing enclosure column with lateral support described above, it is characterized in that: bolt connections are adopted between its various components, and the characteristics of structural prefabrication are realized by the way of fixing the lower part of the forward support control baffle (22) and the upper part of the forward support bolt (8) to fix the baffle (22), improving the construction efficiency and the reuse rate of components.

[0017] For the prefabricated shock-absorbing enclosure column with lateral support described above, it is characterized in that: in order to ensure the functions of the forward support and the lateral support, it is required that the length of the forward support main board (5) and the lateral support main board (10) reaches 1 / 3 - 1 / 2 of the length of the outer column (2), the length of the forward support bottom board (6) reaches about 1 / 3 of the length of the outer column (2), and the length of the lateral support bottom board (11) is not less than 1 / 5 of the length of the outer column (2).

[0018] For the prefabricated shock-absorbing enclosure column with lateral support described above, it is characterized in that: in order to ensure sufficient stiffness of the forward support and the lateral support, it is required that the widths of the forward support main board (5), the forward support bottom board (6), the lateral support main board (10), and the lateral support bottom board (11) are not greater than 4 cm, and the thicknesses are not less than 1 cm.

[0019] For the prefabricated shock-absorbing enclosure column with lateral support described above, it is characterized in that: in order to firmly fix the enclosure column to the ground with the fastening bolt (13), compared with the traditional fastening bolt, the screw length of the fastening bolt (13) is increased, and it is not less than 8 cm.

[0020] For the prefabricated shock-absorbing enclosure column with lateral support described above, it is characterized in that: the materials of other components except the polyurethane rubber coating are all construction steel, and its yield strength should not be less than 180 MPa.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] 1. The prefabricated shock-absorbing enclosure column with lateral support uses a foldable lateral support to replace the base of the traditional enclosure column, increasing the contact area with the ground and the resistance arm, and significantly improving the lateral bearing capacity of the construction site enclosure.

[0023] 2. The prefabricated vibration-damping enclosure column with lateral support adopts double columns. By adjusting the bolts between the columns, the height of the column can be changed, which is convenient for the enclosure column to adjust its height to meet the requirements of different baffle heights.

[0024] 3. The prefabricated vibration-damping enclosure column with lateral support uses polyurethane-coated bolts instead of traditional connecting bolts to connect the column body and the lateral support. While transmitting the force of the enclosure column body to the lateral support, it undergoes elastoplastic deformation, absorbs part of the energy, and achieves the purpose of vibration reduction and energy dissipation, thereby enhancing the service life of the enclosure column.

[0025] 4. All components of the prefabricated vibration-damping enclosure column with lateral support and the connection between the enclosure column and the ground are made by bolts. The lateral support and the longitudinal support can be folded and stored. The enclosure baffle and the enclosure column are simply connected by bolts and the longitudinal support, which is convenient for the quick disassembly and installation of the entire enclosure structure and improves the construction efficiency of the enclosure.

[0039] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] As Figure 1 shown, an example of the prefabricated shock-absorbing enclosure column with lateral supports of the present invention mainly includes an inner column (1), an outer column (2), an adjustment bolt (3), an adjustment bolt hole (4), a longitudinal support main board (5), a longitudinal support bottom board (6), a longitudinal support rotating bolt (7), a longitudinal support bolt (8), a longitudinal support storage bolt hole (9), a lateral support main board (10), a lateral support bottom board (11), a lateral support rotating bolt (12), a fastening bolt (13), a polyurethane-coated bolt (14), a lateral support storage bolt hole (15), a longitudinal support bolt hole (16), and a lateral support bolt hole (17), etc.

[0041] The implementation steps are as follows:

[0042] For a prefabricated shock-absorbing enclosure column with lateral supports, the length of the outer column is 1.8 m, and its cross-sectional area is 50 cm 2 , the length of the inner column is 1.2 m, and its cross-sectional area is 42 cm 2 , the thicknesses of both the inner column and the outer column are 2 mm, and there is a 1-mm gap between them. Looking at the cross-sections of the inner column and the outer column, the core area is a rectangle of 50 mm × 90 mm. The parts extending out of the core rectangle have a length of 55 mm and widths of 12 mm and 18 mm respectively. Six evenly distributed adjustment bolt holes are arranged at the upper parts of the inner column and the outer column, with an interval distance of 15 cm, facilitating the change of the height of the inner column.

[0043] The thickness of the forward support bottom plate, forward support main board, lateral support bottom plate, and lateral support main board is 1 cm, and the width is 3 cm; the length of the forward support bottom plate is 60 cm, the length of the main board is 100 cm, the length of the lateral support bottom plate is 45 cm, and the length of the main board is 90 cm; the length of the fastening bolt screw is 10 cm, and 2 fastening bolt holes are arranged on the lateral support bottom plate with a spacing distance of 15 cm.

[0044] Along the direction of the enclosure baffle, two groups of forward supports are set on both the front and rear sides of the enclosure column. After the two groups of forward supports are unfolded, the enclosure baffle can be fixed therein to prevent the baffle from deflecting left and right. From the outer column, 2 forward support bolt holes are set from bottom to top, with a height of 1.5 cm and 81.5 cm; 1 forward support storage bolt hole is set, with a height of 161.5 cm. Along the direction of the enclosure baffle, one group of lateral supports is set on both the left and right sides of the enclosure column, and 2 lateral support bolt holes are set from the outer column from bottom to top, with a height of 3 cm and 81 cm; 1 lateral support storage bolt hole is set, with a height of 138 cm. The above is the description of the setting of the bolt hole positions of one group of forward supports and one group of lateral supports. The bolt holes of other forward supports and lateral supports are symmetrically set with reference to the above description.

[0045] The inner diameter of the polyurethane rubber coating is 1 cm, the outer diameter is 3 cm, the thickness is 2 cm, and the length is 8 cm. Its material is polyurethane rubber, and its hardness is Shore A70; the diameter of the screw of the polyurethane rubber coating bolt is 1 cm, the outer diameter of its nut is 2 cm, and the length is 10 cm. The diameters of the adjustment bolt, forward support bolt, and forward support rotating bolt are all 2 cm.

[0046] In this example of the enclosure column, the materials of other components except the polyurethane rubber coating are all stainless steel SUS201.

[0047] Before installation, the inner column, outer column, forward support main board, forward support bottom plate, lateral support main board, and lateral support bottom plate are connected together, as Figure 10 shown. The inner column and the outer column are connected by an adjustment bolt. The forward support main board and the forward support bottom plate form a forward support, and the two are hinged by a forward support rotating bolt. The lateral support main board and the lateral support bottom plate form a lateral support, and the two are hinged by a lateral support rotating bolt. The forward support is connected to the outer column by passing the forward support bolt through the end of the forward support main board and inserting it into the forward support storage bolt hole, and passing the forward support bolt through the end of the forward support bottom plate and inserting it into the forward support bolt hole at the bottom of the outer column; the lateral support is connected to the outer column by passing the polyurethane rubber coating bolt through the end of the lateral support main board and inserting it into the lateral support storage bolt hole, and passing the polyurethane rubber coating bolt through the end of the lateral support bottom plate and inserting it into the lateral support bolt hole at the bottom of the outer column.

[0048] At the initial installation, the height of the inner column relative to the outer column is changed by installing the adjustment bolts into different adjustment bolt holes, thereby changing the height of the column. If it is necessary to lower the height of the column, install the two adjustment bolts into the two adjustment bolt holes near the upper part of the outer column; if it is necessary to increase the height of the column, install the two adjustment bolts into the two adjustment bolt holes near the lower part of the outer column.

[0049] Expand the lateral support, remove the polyurethane-coated bolts from the lateral support storage bolt holes, keep the others unchanged, lower the end of the lateral support main board along the edge of the outer column to the lateral support bolt hole at the waist of the outer column, and then connect the lateral support main board and the outer column with the polyurethane-coated bolts. Pass the fastening bolts through the fastening bolt holes on the lateral support bottom plate and fix the lateral support to the ground. The process of lowering the end of the lateral support main board along the edge of the outer column is shown in Figure 11 , and the lateral supports on both sides of the column are expanded in the above manner.

[0050] Expand the longitudinal support, remove the longitudinal support bolts from the longitudinal support storage bolt holes, keep the others unchanged, lower the end of the longitudinal support main board along the edge of the outer column to the longitudinal support bolt hole at the waist of the outer column, and then connect the longitudinal support main board and the outer column with the longitudinal support bolts. The process of lowering the end of the longitudinal support main board along the edge of the outer column is shown in Figure 11 , and the longitudinal supports on both sides of the column are expanded in the above manner.

[0051] After the installation of the enclosure column is completed, place the enclosure baffle in the gap of the expanded longitudinal support main board, pass the longitudinal support bolts through the longitudinal support storage bolt holes and fix the enclosure baffle, thereby completing the installation of the assembled vibration damping enclosure with lateral supports.

[0052] The above is a typical example of the present invention, but the implementation of the present invention is not limited thereto.
