[0002] For important buildings requiring concealed construction, or critical facilities requiring concealed operation, or other situations necessitating the provision of large-span spaces, the required concealment space is substantial. This often necessitates the use of tunneling or the construction of large-span steel structures for concealment. However, existing technologies present challenges in fabricating these structures and suffer from lengthy construction periods when concealing important buildings. Therefore, measures are needed to address these issues. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a shielding cable space structure frame and construction method, solving the problems of difficult manufacturing and long construction period in existing buildings.

[0004] The technical solution to achieve the above objective is: a shielding cable space structure frame and construction method, used to shield equipment on the construction site, the structure frame comprising:

[0005] Locking posts are installed on both sides of the equipment at the construction site, and the locking posts are provided with multiple reserved holes;

[0006] Multiple vertical columns are spaced apart on the side of the locking pile closest to the equipment on the construction site.

[0007] The main cable is connected to the vertical columns that are set opposite to each other. One end of the main cable passes through the reserved hole on the locking pile on one side of the site equipment and is locked. The other end of the main cable passes through the top of the vertical columns on both sides of the site equipment and then through the reserved hole on the locking pile on the other side for tensioning and locking.

[0008] A shielding net is attached to a vertical column on one side of the equipment on the construction site. The shielding net has buckles spaced at intervals corresponding to the main cable. The buckles are sleeved on the corresponding main cable. The shielding net is slidably connected to the main cable through the buckles. The shielding net can be unfolded along the main cable toward the vertical column on the other side of the equipment on the construction site.

[0009] A further improvement of the technical solution of the present invention is that: the shielding net is provided with a limiting buckle facing the vertical column on the other side of the equipment on the construction site, and the bottom of the limiting buckle is connected to the top of the buckle.

[0010] A further improvement to the technical solution of the present invention is that: a diagonal bracing column is connected to the side of the vertical column near the locking pile.

[0011] A further improvement of the technical solution of the present invention is that: a sleeve is connected to the top of the vertical column, the inner wall of the sleeve is in contact with the surface of the main cable, and the main cable is tensioned by passing through the sleeve.

[0012] A further improvement of the technical solution of the present invention is that: the inner wall of the sleeve facing the locking post has an arc shape extending from the inside to the outside.

[0013] A further improvement of the technical solution of the present invention is that: the side of the locking pile away from the inclined support is connected to an anchor cable, and the anchor cable is embedded in the construction site.

[0014] A further improvement of the technical solution of the present invention is that: the shielding net is connected with auxiliary cables perpendicular to the main cable, and the auxiliary cables are spaced apart on the shielding net.

[0015] A further improvement of the technical solution of the present invention is that: a connecting crossbar is connected to the top of the vertical column located on the same side, and a plurality of fixing hooks are connected to the connecting crossbar;

[0016] The shielding net has multiple tie ropes attached to the side near the connecting crossbeam, and the tie ropes are tied to the fixed hooks.

[0017] A further improvement of the technical solution of the present invention is that: an intersecting auxiliary support is connected between two adjacent vertical columns and near the bottom of the connecting crossbeam.

[0018] A construction method for a shielding cable-stayed spatial structure includes the following steps:

[0019] Step 1: Provide locking posts and set them on both sides of the equipment on the construction site;

[0020] Step 2: Provide vertical columns and set them up at intervals on both sides of the equipment on the construction site;

[0021] Step 3: Provide the main cable, connect and lock one end of the main cable through the locking pile, and then connect the other end of the main cable through the top of the two oppositely set vertical columns to the locking pile on the other side and lock it after tensioning.

[0022] Step 4: Provide a shielding net, connect the shielding net to a vertical post on one side of the equipment on the construction site, place the shielding net on the main cable, and stretch the other end of the shielding net on the main cable to make the shielding net spread out on the main cable.

[0023] By utilizing the above technical solution, the technical effects achieved by the present invention compared to the prior art are as follows:

[0024] This invention provides a spatial structure frame and construction method for a shielding net cable. It utilizes the unidirectional tension of the main cable for structural support, locking the two ends of the main cable to the pre-drilled holes on the locking piles. Vertical columns are then used to support the main cable, and the vertical columns on both sides are quickly connected to achieve the structural support function after tension is applied. By manually pulling the shielding net below the main cable, a relatively simple shielding method can be quickly provided for the construction of important buildings or the concealed operation of important facilities, achieving the effect of simple construction.

[0025] The sleeve at the top of the vertical column can reduce wear on the surface of the main cable by utilizing the arc-shaped inner wall of the sleeve end, preventing surface damage to the main cable during connection and extending the service life of the main cable.

[0026] The auxiliary cables allow the shielding net to be folded on the main cable, increasing its strength and service life. This provides conditions for the construction and installation of the cable-net space structure, enabling the cable-net structure to be quickly recycled and accelerating the construction cycle.

The following is in conjunction with... Figures 1 to 13 The structure of the shielding cable space structure frame and construction method of the present invention will be described.

[0044] See Figure 1 , Figure 2 , Figure 11This invention provides a shielding net cable space structure frame and construction method for shielding equipment on a construction site. The structure frame includes: vertical columns 1, locking posts 3, shielding net 4, main cables 5, and buckles 16. The locking posts 3 are set on both sides of the equipment on the construction site, and each locking post 3 has multiple reserved holes. The vertical columns 1 are spaced apart on the side of the locking posts 3 closest to the equipment on the construction site. There are multiple vertical columns 1. The main cables 5 are connected to the oppositely arranged vertical columns 1. One end of the main cable 5 passes through the reserved hole on the locking post 3 on the side of the equipment and is locked. The other end of the main cable 5... One end of the netting passes through the top of the vertical columns 1 on both sides of the equipment and then through the reserved hole on the locking pile 3 on the other side for tensioning and locking. The netting 4 is connected to the vertical column 1 on one side of the equipment on the construction site. The netting 4 is provided with buckles 16 at intervals corresponding to the main cable 5. The buckles 16 are sleeved on the corresponding main cable 5. The netting 4 is slidably connected to the main cable 5 through the buckles 16. The netting 4 can be unfolded along the main cable 5 toward the vertical column on the other side of the equipment on the construction site. By locking one end of the main cable 5 to the reserved hole on the locking pile 3, the locking pile 3 is away from the vertical column. An anchor cable 12 is connected to one side of the main cable 1. This anchor cable 12 is embedded in the construction site. The site is leveled according to the required elevation. After leveling, the anchor cable 12 for the locking pile 3 is installed first. Before installing the locking pile 3, the anchor cable 12 needs to be drilled and lowered. The specifications, length, and arrangement of the anchor cable 12 need to be calculated based on the tension value of the main cable 5. The installation of the anchor cable 12 should ensure that its position is consistent and corresponds to the position of the locking pile 3, facilitating subsequent tensioning and locking after the locking pile 3 is installed. Anchors 20 are installed at the pre-reserved holes on the locking pile 3 where the main cable 5 and the anchor cable 12 pass through. The anchors are positioned according to the span of the equipment on the site. The upper load calculated by height and other parameters requires the construction of piles using vertical columns 1 first, followed by the construction of the foundation cap and locking piles 3. The vertical columns 1 support the main cable 5, and the other end of the main cable 5 is then connected to the reserved hole of the locking pile 3 on the other side through tensioning and locked. Before locking, the main cable 5 is tensioned again so that the main cable 5 is tensioned and stressed on the vertical columns 1. The tension force of the main cable 5 is transferred to the ground using the locking piles 3. The vertical columns 1 and locking piles 3 then support the space between the shielding net 4 and the main cable 5, achieving a linear stress effect and forming a stable structure.

[0045] Better, such as Figure 2 As shown, the upper end of the vertical column 1 can be supported by the connecting crossbar 9, so that the vertical column 1 is always in a vertical state and the upper end of the vertical column 1 is not tilted when it is erected.

[0046] Furthermore, such as Figure 11As shown, the anchor 20 can lock the main cable 5 and the anchor cable 12 after they pass through the reserved hole on the locking pile 3, so that the main cable 5 and the anchor cable 12 are fixed after passing through the locking pile 3. The inclined brace 2 and the locking pile 3 are filled with high-strength grout 19 with micro-expansion and non-shrinkage. Before grouting, it is necessary to ensure that the inclined brace 2 and the locking pile 3 are installed in place and completed acceptance.

[0047] Furthermore, during the installation of the steel support, the anchor cable 12 can be constructed simultaneously. After the steel support and anchor cable 12 are completed, grouting is carried out under the vertical column 1 and the diagonal brace 2. The vertical column 1 and the locking pile 3 form the linear force-bearing foundation at both ends of the cable net space, bearing the tension and self-weight load of the main cable 5 and the shielding net 4 in the upper part of the cable net space. The locking crown beam formed by the vertical column 1, the diagonal brace 2, the main cable 5, and the locking pile 3 forms a stable structure.

[0048] refer to Figure 3 , Figure 4 , Figure 10 In one specific embodiment of the present invention, the shielding net 4 is provided with a limiting buckle 15 corresponding to the buckle 16. The bottom of the limiting buckle 15 is connected to the top of the buckle 16. The limiting buckle 15 is provided with metal rings 17 connecting the shielding net 4 on both sides facing the shielding net 4. After the shielding net 4 and the buckle 16 are sewn together, the net cable can be installed. The installation method is to lift the folded net cable to the main cable at the top of the column at one end of the steel support position, and use the pressing opening ring to attach the special buckle 16 on the net cable to the main cable 5 from far to near.

[0049] Better, such as Figure 8 , Figure 13 As shown, after ensuring the main cable 5 is tensioned, the limiting buckle 15 is used to attach it to the auxiliary cable 13, and then the shielding net 4 is reinforced by the metal ring 17, which is a ring-shaped buckle with a perforated structure. Then, it is attached to the main cable 5 by the buckle 16, so that the shielding net 4 covers the main cable 5. When the shielding net 4 is unfolded, the limiting buckle 15 and the buckle 16 can be used to pull and stretch the main cable 5. The main cable 5 is made of galvanized steel strand, and the specifications are calculated according to the load. The length is calculated according to the span, height, deflection length, and tensioning allowance. The traction method can be manual traction, with a traction rope set at the end of the shielding net 4 in advance to achieve the traction effect, or traction can be carried out by electric pulley.

[0050] In one specific embodiment of the present invention, a diagonal bracing column 2 is connected to the side of the vertical column 1 near the locking pile 3, and a pile body 6 extending into the construction site is connected to the bottom of the vertical column 1. A stiffening plate 18 is provided on the surface of the vertical column 1 near the ground. A high-strength grouting material 19 with micro-expansion and no shrinkage is poured between the vertical column 1 and the construction ground. Before grouting, it is necessary to ensure that the vertical column 1 is installed in place and completed the acceptance. After the grouting strength of the grouting material 19 meets the strength requirements and the grouting of the anchor cable 13 has reached the strength requirements, the main cable 5 is tensioned.

[0051] Furthermore, such as Figure 3 , Figure 4 As shown, the pile body 6, which extends into the site, strengthens the support effect of the vertical column 1, effectively preventing the vertical column 1 from tilting. The sleeve 11 can restrict the main cable 5 to the top of the vertical column 1, making it less likely for the main cable 5 to shift when placed above the vertical column 1.

[0052] In one specific embodiment of the present invention, a sleeve 11 is connected to the top of the vertical column 1, the inner wall of the sleeve 11 is in contact with the surface of the main cable 5, and the main cable 5 is tensioned by passing through the sleeve 11.

[0053] refer to Figure 9 In one specific embodiment of the present invention, the inner wall of the sleeve 11 facing the locking post 3 is provided with an arc shape extending from the inside to the outside.

[0054] Furthermore, such as Figure 9 As shown, the inner diameter of the sleeve 11 end is set to be arc-shaped, which can reduce friction when the main cable 5 passes through and is placed, and reduce the wear of the inner diameter on the main cable 5.

[0055] refer to Figure 3 In one specific embodiment of the present invention, the side of the locking pile 3 away from the inclined support 2 is connected to the anchor cable 12, and the anchor cable 12 is embedded in the construction site.

[0056] Better, such as Figure 3 As shown, the anchor cable 12 can be extended into the construction site to further fix the locking pile 3 in the construction site and enhance the stability of the locking pile 3.

[0057] refer to Figure 6 , Figure 7 In one specific embodiment of the present invention, an auxiliary cable 13 perpendicular to the main cable 5 is connected to the shielding net 4, the auxiliary cables 13 are spaced apart on the shielding net 4, and a sewing rope 14 is connected to the shielding net 4 to sew the shielding net 4 and the auxiliary cable 13 together.

[0058] Furthermore, such as Figure 6 , Figure 7 As shown, the auxiliary cables 13 spaced apart on the shielding net 4 allow the shielding net 4 to be folded.

[0059] Furthermore, by using sewing rope 14 to sew the connection between the shielding net 4 and the auxiliary cable 13, the two are more closely fitted and less prone to loosening.

[0060] refer to Figure 8 In one specific embodiment of the present invention, a connecting crossbeam 9 is connected to the top of the vertical column 1 located on the same side, and a plurality of fixing hooks 7 are connected to the connecting crossbeam 9. A plurality of tie ropes 8 are connected to the side of the shielding net 4 near the connecting crossbeam 9, and the tie ropes 8 are tied to the fixing hooks 7.

[0061] Furthermore, such as Figure 5 As shown, the shielding net 4 is placed on top of the main cable 5, and the tie rope 8 on one side of the shielding net 4 is tied to the fixing hook 7 for connection, so as to fix the end of the shielding net 4.

[0062] refer to Figure 2 In one specific embodiment of the present invention, intersecting auxiliary supports 10 are connected between two adjacent vertical columns 1 and near the bottom of the connecting crossbeam 9.

[0063] Furthermore, such as Figure 2 As shown, the auxiliary support 10 is made of I-beams and supports the vertical column 1.

[0064] A construction method for a shielding cable-stayed spatial structure includes the following steps:

[0065] Step 1: Provide locking stakes 3 and set them on both sides of the equipment on the construction site to facilitate locking of the anchor cables for ground gripping and locking of the main cable tensioning.

[0066] Step 2: Provide vertical column 1. Place vertical column 1 at intervals on both sides of the equipment on the construction site. If the upper load requires pile foundation based on the span, height and other calculations, carry out pile construction first, and then construct the foundation cap and locking crown beam. After the foundation cap steel reinforcement is installed, anchor bolts need to be pre-embedded. The pre-embedded position must correspond to the column position. Then provide diagonal bracing 2, pile body 6, connecting cross frame 9 and sleeve 11. Bury the pile body 6 at the bottom of vertical column 1 into the site soil to enhance the support effect of vertical column 1. Then install diagonal bracing 2 on locking pile 3 and connect it to vertical column 1. Use diagonal bracing 2 to reinforce and support vertical column 1. Then weld connecting cross frame 9 between two adjacent vertical columns 1. Then install sleeve 11 on the top of vertical column 1.

[0067] Step 3: Provide the main cable 5, pass one end of the main cable 5 through the locking pile 3 for connection and locking, and then pass the other end of the main cable 5 through the top of the two oppositely arranged vertical columns 1 to the locking pile 3 on the other side for locking after tensioning. Then provide the fixing hook 7 and install the fixing hook 7 on the top of the connecting crossbar 9 to increase multiple connection points by setting the fixing hook 7.

[0068] Step 4: Provide a shielding net 4 and connect it to the vertical column 1 on one side of the equipment on the construction site. Then place the shielding net 4 onto the main cable 5 and stretch the other end of the shielding net 4 onto the main cable 5 to allow the shielding net 4 to unfold on the main cable 5. Provide a tie rope 8 and place the shielding net 4 onto the main cable 5. Connect the tie rope 8 to both ends of the shielding net 4 near the connecting crossbar 9. First, connect one end of the tie rope 8 to the fixing hook 7 on one side of the connecting crossbar 9. Then stretch and unfold the shielding net 4 onto the main cable 5. Subsequently, connect the other end of the tie rope 8 to the fixing hook 7 on the other side of the connecting crossbar 9. After the shielding space structure is completed, the internal forces of the steel columns, steel strands, and anchor bolts need to be monitored regularly. The steel support area needs to be protected to prevent mechanical damage to the structure.

[0069] Furthermore, the fourth step also includes: providing auxiliary cable 13, sewing thread 14, limiting buckle 15, clip 16, and metal ring 17; placing the auxiliary cable 13 horizontally on the shielding net 4; then using the sewing thread 14 to sew the auxiliary cable 13 to the shielding net 4; then connecting the limiting buckle 15 to the auxiliary cable 13; then installing the clip 16 to the bottom of the limiting buckle 15; and then connecting the shielding net 4 to the limiting buckle 15 through the metal ring 17, so that the limiting buckle 15 can be moved while the shielding net 4 is moving. The net cables are sewn according to the design spacing of the auxiliary cable 13. The selection of the shielding net 4 is determined according to the shielding requirements. The auxiliary cable 13 is selected and its material and specifications are determined according to the span of the main cable 5 and the local wind load. The sewing is done on-site with nylon thread or directly processed in the factory. Then, by installing the clip 16 on the main cable 5, the limiting buckle 15 and the clip 16 are used to perform traction and tension activities on the main cable 5.

[0070] The beneficial effects of the shielding cable space structure frame and construction method of the present invention are as follows:

[0071] 1. A special buckle is used to attach the net cable structure to the main cable. The special buckle consists of two collars, one of which is fastened to fix it to the net cable, and the other can be pressed open to facilitate attachment to the main cable and allow the net cable to slide on the main cable.

[0072] 2. By using stitching lines to sew the main cable and the shielding net, the strength and service life of the shielding net are increased, providing conditions for the construction and installation of the cable-net space structure, enabling the cable-net structure to be completed quickly and accelerating the construction cycle.

[0073] 3. The sleeve at the top of the vertical column can reduce wear on the surface of the main cable by utilizing the arc-shaped inner wall of the sleeve end, preventing surface damage to the main cable during connection and extending the service life of the main cable.

[0074] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
