Description

Technical Field

[0001] The present invention belongs to the technical field of construction engineering, and particularly relates to a wind-resistant multi-section attached frame column device and a construction method thereof. Background Art

[0002] Affected by its climate, some areas have large precipitation, resulting in a soil type of high water table soft soil structure. When the construction site is in a special geological condition of high water table soft soil foundation and adjacent to a rock wall, the conventional construction method of high frame structure faces many problems. The soft soil foundation has low bearing capacity, and the high water table will further reduce the soil strength, increasing the risk of foundation settlement and high frame structure inclination; being adjacent to the rock wall limits the layout space of the high frame structure foundation, and the influence of the rock wall on the high frame structure needs to be considered during the construction process.

[0003] At the same time, under harsh weather conditions such as strong winds, the high frame structure faces huge wind load effects. The wind load may cause the structure to vibrate, deform or even collapse, seriously threatening the building safety and service life. At present, there are many deficiencies in the commonly used wind-resistant measures. For example, the traditional reinforcement methods have limited improvement on the structural integrity and cannot effectively disperse and resist wind loads in different directions; some wind-resistant devices are complex to install and costly, making it difficult to be widely applied. Therefore, it is of great practical significance to develop a wind-resistant multi-section attached frame column device that is efficient, economical and easy to install. Summary of the Invention

[0004] The purpose of the present invention is to provide a wind-resistant multi-section attached frame column device and a construction method thereof, so as to solve the technical problems that the traditional high frame structure cannot be effectively constructed in the area adjacent to the rock wall and has poor wind resistance.

[0039] Refer to the attached Figure 1-7 As shown, according to the embodiment of the present application, it includes:

[0040] Tower base 2, which is arranged at the corresponding position of the construction site and is provided with a ground connection end thereon;

[0041] It should be noted that before the construction of the tower base 2, the ground of the construction site needs to be paved, so that the strata of the construction site are, from top to bottom, artificial fill layer (Q4ml), upper Pleistocene alluvial layer (Q3al) and underlying Permian Lower Series Maokou Formation bedrock (P1m). The characteristics of each rock and soil layer are described below:

[0042] (1) Quaternary artificial fill layer (Q4ml)

[0043] Plain fill: Yellowish-brown, in a loose soil state, mainly composed of silty clay and a small amount of crushed stone and humus, and is recently backfilled soil. It has not been compacted, with a loose structure and poor uniformity. This layer is distributed in most parts of the whole site, with an exposed layer thickness of 0.50 - 22.30m, an average thickness of 6.02m, a top elevation of 67.72 - 150.03m, and a bottom elevation of 62.02 - 134.73m.

[0044] (2) Upper Pleistocene alluvial layer (Q3al)

[0045] Silty clay: Distributed in parts of the whole site, and this layer was revealed by 70 boreholes in total. Yellowish-brown, hard plastic, mainly composed of clay particles, followed by silt particles. High toughness, high dry strength, smooth cut surface, no shaking reaction, and relatively uniform soil quality. The average compression coefficient is 0.20 MPa-1, and the average compression modulus is 8.84 MPa. The measured standard penetration blow count is 15-18 blows, and the corrected standard value is 14.16 blows. The statistical results of its in-situ test are shown in Table 3.3. The revealed layer thickness is 1.10-17.00 m, with an average thickness of 6.47 m. The elevation of the layer top is 63.92-108.09 m, the elevation of the layer bottom is 49.67-103.53 m, and the buried depth of the layer top is 1.00 m-22.30 m.

[0046] (3) Bedrock of the Lower Permian Maokou Formation (P1m)

[0047] Medium-weathered limestone: Distributed throughout the whole site. Greyish-white to greyish-black, cryptocrystalline structure, medium-thick bedded structure. The rock joints and fissures are slightly developed, and calcite veins are occasionally seen filling in the gaps, showing a dendritic distribution. The rock cores are mostly short columnar, columnar, and a small amount are long columnar and massive. The joint length is 5-35 cm, and the longer ones reach 40-55 cm. The block diameter is 5-15 cm, and the recovery rate RQD = 85. The hammering sound is clear and crisp. The rock is hard and its strength is relatively hard rock. The basic rock mass quality grade is IV. The standard value of the uniaxial compressive saturated strength is 33.50 Mpa. No adverse geological phenomena such as free face, fracture zone, cave, and soft interlayer are seen within the scope of this exploration depth. The revealed layer thickness is 5.00-16.00 m, with an average layer thickness of 10.33 m. The buried depth of the layer top is 0.00-29.20 m, and the elevation of the layer top is 49.67-293.64 m.

[0048] During the construction of Tower Foundation 2, it includes:

[0049] A foundation pit, which is set at the designated position of the construction site and has a receiving cavity with an open top inside;

[0050] Vertical reinforcement, which is arranged in a matrix in the receiving cavity and is fixedly connected to the side wall of the foundation pit;

[0051] Anchor bolts, which are arranged in a matrix on the vertical reinforcement and are fixedly connected to the vertical reinforcement. Their ends penetrate out of the receiving cavity and are connected to the elevator shaft 1;

[0052] A cushion layer, which is set in the receiving cavity as the filling material of the receiving cavity to form Tower Foundation 2.

[0053] In other words, after the foundation pit is excavated, vertical steel bars arranged in a matrix are preset inside the foundation pit. There is a spacing between adjacent vertical steel bars, and anchor bolts are arranged on the vertical steel bars so that the top of the anchor bolts penetrates out of the foundation pit. The anchor bolts and the vertical steel bars are arranged vertically. Then, pouring is carried out. Before pouring, the perpendicularity and centrality of the anchor bolts need to be verified. When the requirements are met, C15 concrete is poured in the foundation pit. It should be further noted that 100-mm-thick C15 concrete is used in the tower foundation 2, and the tower foundation 2 extends 100 mm beyond each side of the foundation of the frame structure. The foundation uses 1350-mm-thick C35 concrete, and steel bars are embedded around the foundation. The embedded position, specifications, and spacing are the same as the raft reinforcement at this location, and the anchorage length meets the requirements.

[0054] The elevator shaft frame 1 is gradually arranged on the tower foundation 2, and the bottom elevator shaft frame 1 is connected to the ground connection end. A first connection end and a second connection end are provided on the elevator shaft frame 1.

[0055] In other words, the elevator shaft frame 1 is composed of multiple sections of elevator shaft frames 1. Adjacent elevator shaft frames 1 are connected in series by welding, pins, and bolts to form an integrated elevator shaft frame 1. A connection damper can also be used for connection. The connection damper uses a viscous damper or a metal damper, which can effectively consume the vibration energy generated by the structure under the action of wind load and reduce the vibration amplitude of the structure. The parameters of the damper are optimized according to the characteristics of the building structure and the design wind load to achieve the best energy dissipation and vibration reduction effect. The elevator shaft frame 1 is composed of several vertical bars, horizontal bars, support beams, and diagonal bars. Among them, a first vertical surface, a second vertical surface, and a third vertical surface in the shape of a rectangle are formed by several vertical bars and horizontal bars. The first vertical surface, the second vertical surface, and the third vertical surface are connected by support beams to form a rectangular frame structure. A passage is provided between the second vertical surface and the third vertical surface. The diagonal bars are arranged on the second vertical surface, the third vertical surface, and the side wall of the passage. The diagonal bars form a cross structure with the second vertical surface, an inclined support structure with the third vertical surface, and an X-shaped structure with the side wall of the passage. By using the combination of a rectangular frame, a cross frame, and an X-shaped frame, not only the overall weight of the elevator frame is reduced, but also the overall wind resistance is reduced, the air flow in the elevator shaft frame 1 is accelerated, and the wind resistance effect is enhanced.

[0056] The first support 3 is arranged on the first connection end of the elevator shaft frame 1. One end of it is fixedly connected to the elevator shaft frame 1, and the other end is fixedly connected to the attachment wall.

[0057] The second support 4 is arranged on the second connection end of the elevator shaft frame 1. One end of it is fixedly connected to the elevator shaft frame 1, and the other end is fixedly connected to the attachment wall.

[0058] Support platform 6, the support platform 6 is provided at the top of the elevator shaft tower 1, and is fixedly connected to the elevator shaft tower 1, and is provided with a third connection end thereon;

[0059] It should be noted that, as Figure 6 shown, the support platform 6 is composed of an upper curved rod, a lower curved rod, vertical beams, cross beams and inclined beams. Among them, the upper curved rod and the lower curved rod are arranged in a sleeved manner, and there is a longitudinal distance between the two. The upper curved rod and the lower curved rod are concentric, and a through hole is provided at the center. The through hole communicates with the passage of the elevator shaft tower 1. The vertical beams are arranged in an annular array between the upper curved rod and the lower curved rod, and both ends thereof are fixedly connected to the upper curved rod and the lower curved rod. The cross beams connect the adjacent upper curved rods and the adjacent lower curved rods respectively, and inclined beams are provided between the adjacent upper curved rod and the lower curved rod, thereby forming a frame structure. Among them, the area of the upper curved rod is larger than that of the lower curved rod, forming an inverted frustum structure, and a third connection end is provided on one side of the frustum structure.

[0060] It should be further noted that the support platform 6, the elevator shaft tower 1 and the tower base 2 are on the same central line.

[0061] The third support 5, the third support 5 is provided on the third connection end of the support platform 6, one end of which is fixedly connected to the support platform 6, and the other end is fixedly connected to the attachment wall.

[0062] It should be noted that the cross-sectional areas of the first support 3 and the second support 4 in contact with the attachment wall are larger than the cross-sectional areas of their contact ends with the elevator shaft tower 1; the bottom of the third support 5 is an arc structure, and the cross-sectional areas of its two ends in contact with the attachment wall and the elevator shaft tower 1 are larger than the cross-sectional area of the middle end; the first support 3 and the second support 4 are connected to the attachment wall through a connection frame 9, and the two ends of the third support 5 are respectively connected to the elevator shaft tower 1 and the attachment wall through the connection frame 9; among them, the connection frame 9 includes:

[0063] Support beams, the support beams are arranged in a matrix at the top and the bottom. Among them, the support beams at the bottom are arranged obliquely;

[0064] Cross bars, the cross bars are arranged in a matrix on the support beams at the top and the bottom respectively, and are fixedly connected to the support beams;

[0065] Vertical bars, the vertical bars are arranged in a matrix on the cross bars and are fixedly connected to the cross bars to form a rectangular frame structure;

[0066] Inclined bars, the inclined bars are arranged between the rectangular frame structures, and both ends thereof are respectively connected to the support beams at the top and the bottom. The adjacent inclined bars form a V-shaped structure (as Figures 5-7As shown in the figure, the support beam, cross bar, vertical bar, and diagonal bar form a connection framework 9, which is connected to the first support 3, the second support 4, and the third support 5. Among them, the connection framework 9 and the first support 3, the second support 4, and the third support 5 are of an integral structure;

[0067] By adopting a frame structure for the first support 3, the second support 4, and the third support 5, connecting them to the elevator shaft tower 1 and the support platform 6, and matching the connection framework 9 with the corresponding structure to connect to the attachment wall (rock wall), the elevator shaft tower 1 is supported, so that a force is generated between the elevator shaft tower 1 and the attachment wall, improving the overall stability, and further improving the overall wind resistance.

[0068] In order to further improve the overall stability and wind resistance effect, a number of curved columns 7 and ring beams 8 are also provided on the elevator shaft tower 1. The curved columns 7 are arranged in an arc shape on the elevator shaft tower 1, with one end connected to the tower base 2 and the other end connected to the support platform 6; the ring beams 8 are arranged in a circular array between the elevator shaft tower 1 and the curved columns 7. The curved columns 7 and the ring beams 8 are staged along with the construction of the elevator shaft tower 1. The cross-sectional area formed by the bottom curved columns 7 and the ring beams 8 is the same as the cross-sectional area at the top of the support platform 6. By combining the curved columns 7, the ring beams 8 with the elevator shaft tower 1, the elevator shaft tower 1 as a whole forms a structure similar to an hourglass, which not only accelerates the air flow, enables the elevator shaft tower 1 to remain stable in a strong wind environment, but also further supports the elevator shaft tower 1, thus effectively improving the connection stability between the elevator shaft tower 1 and the ground.

[0069] After the framework structure is built, guardrails can be installed on the support platform 6, the first support 3, the second support 4, and the third support 5, and then entertainment facilities can be installed for use. Lifting equipment can be installed in the passage of the elevator shaft tower 1.

[0070] Through the above technical files, the technical effects generated in the embodiments of the present application are as follows:

[0071] By adopting an elevator shaft tower 1 composed of a rectangular frame, a meter-shaped frame, and an X-shaped frame, the overall wind resistance is improved. By optimizing the structure of the tower base 2, the supporting effect of the tower base 2 on the elevator shaft tower 1 is improved, avoiding the hidden danger of settlement. And by adding the first support 3, the second support 4, the support platform 6, and the third support 5 on the elevator shaft tower 1, the connection between the elevator shaft tower 1 and the attachment wall is effectively improved, not only improving the wind resistance, but also improving the overall stability; by adding the curved columns 7 and the ring beams 8 to form a structure similar to an hourglass with the elevator shaft tower 1, optimizing the overall structure, further improving the wind resistance effect and the overall installation stability.

[0074] The anchoring device includes anchor bars, anchor plates and grouting materials.

After connecting the anchor plate to the first connection point, the second layer of anchor bars is installed in the material injection pit, so that the second connection point on the anchor plate passes through the second layer of anchor bars and extends to the outside of the material injection pit, and the grouting material is poured in the material injection pit so that the surface of the material injection pit is flush with the attached wall, and the second connection point on the anchor plate is connected to the first support 3, the second support 4, and the third support 5.

[0075] It should be noted that the cross-sectional area of ​​the injection pit is larger than the cross-sectional area of ​​the connecting frame 9 (preferably, the cross-sectional area of ​​the injection pit is 1.5-2 times the cross-sectional area of ​​the connecting frame 9), and the depth of the injection pit is 1.5m-2m, wherein both ends of the anchor bar pass through the injection pit and are embedded in the attached wall for 30-50cm, and the anchor bars are arranged in a horizontal and vertical staggered manner to form a mesh structure. The thickness of the grouting material poured in the first layer of anchor bars is 30-50cm, and the thickness of the anchor plate is 10-20cm.

[0076] Through the above technical solution, the technical effects produced in the embodiments of the present application are:
