Description

Technical Field

[0001] This application relates to the technical field of civil engineering, and particularly to a large-span spatial curved surface structure that can slide and open / close on the ground Background Art

[0002] The open cut construction technology is often used for deep foundation pits in underground projects such as building construction and subway sections. The traditional open cut underground project construction involves a large amount of earthwork, concrete, and steel bar welding, etc., and the construction management method is relatively extensive, and the environmental protection measures are relatively weak. During the construction process, due to a large number of earthwork excavation, mechanical operation, and hoisting operation processes, a large amount of dust, smoke, and noise are generated at the construction site. And the open cut underground project construction usually has a long cycle, and the dust, smoke, and noise are easy to form a large area of pollution in the operation and surrounding areas, affecting the air quality and environment of the local area, and also bringing serious impacts on the normal life of the surrounding residents. Although temporary enclosure measures will be taken at the construction site during the construction process, the degree of alleviating the environmental impact is limited, and at the same time, the visual effect is poor, which is not coordinated with the surrounding environment, and will largely damage the street facade effect and overall image of the city. In addition, due to the open-air operation, the external weather affects the construction progress, and the construction conditions of the operators are poor, seriously affecting the labor efficiency

[0003] At present, green construction, dust prevention and noise reduction, and green building measures such as civilized construction sites are strongly advocated at the construction site. For example, in a narrow site, fixed shed covers are used in a local area. Although it can play a role in protecting against wind and rain and ensuring the normal operation of production processes, tools, etc. to a certain extent, it still cannot solve the technical problems such as synchronous construction of multiple working faces of deep foundation pits in the whole area in rainy and snowy days, dust prevention and noise reduction, and vertical transportation of the open cut site. Based on this, this application proposes a large-span spatial curved surface structure that can slide and open / close on the ground, so that it can be applied to the closed structure of open cut construction of underground projects Summary of the Utility Model

[0020] Optionally, both the support grid and the support frame are made of stainless steel;

[0021] Both the first flexible film layer and the second flexible film layer are made of polyethylene or polyvinyl chloride.

Detailed implementation manners

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts also belong to the scope of protection of the present application.

[0041] Refer to Figures 1 to 15 , the present application provides a floor-mounted slidable open-close large-span space curved surface structure, including:

[0042] A plurality of sliding components 100 are arranged at equal intervals on both sides in the width direction of the foundation pit 200. The bottom of each sliding component 100 is slidably connected to both sides in the width direction of the foundation pit 200 and can slide along the length direction of the foundation pit 200; wherein, the foundation pit 200 is an earth pit excavated at the basic design position according to the base elevation and the basic plane size. The size of the foundation pit in the present application can be set according to actual construction requirements. Therefore, the present application does not specifically limit it here.

[0043] A plurality of opening and closing components 300 are provided, with one opening and closing component 300 arranged between every two adjacent sliding components 100. The top of each opening and closing component 300 is higher than the top of each sliding component 100, and the bottom of each opening and closing component 300 is at a preset distance from the top surface in the width direction of the foundation pit 200 (wherein, the value of the preset distance can be set according to actual needs, and the purpose is to ensure that the bottom of the opening and closing component 300 does not contact the top surfaces on both sides in the width direction of the foundation pit 200. Therefore, the present application does not make specific limitations on it here). The opposite sides of each opening and closing component 300 are respectively slidably connected and fixedly connected to the two adjacent sliding components 100; that is to say, during the process of the bottom of the sliding component 100 fixedly connected to the opening and closing component 300 sliding along the length direction of the foundation pit 200 on both sides in the length direction of the foundation pit 200, it drives the opening and closing component 300 to slide along the sliding component 100 with which it is slidably connected and overlap with this sliding component 100, thereby realizing the opening of the large-span spatial curved surface structure that can be slid open and closed when landing and the opening of the top of the foundation pit 200 corresponding to the sliding component 100. The open area of the foundation pit 200 can utilize an external tower crane to solve the problem of vertical transportation at the construction site, thus realizing all-weather construction operations of the foundation pit 200.

[0044] Among them, the opening and closing of the opening and closing component 300 and the occlusion or opening of the foundation pit 200 corresponding to the sliding component 100 are realized by the sliding of the sliding component 100 along the length direction of the foundation pit 200. The sliding component 100 in the present application can play a role in supporting the opening and closing component 300.

[0045] The floor-mounted slidable opening and closing large-span space curved surface structure provided by the present application has multiple sliding components 100 arranged at equal intervals across both sides in the width direction of the foundation pit 200, and an opening and closing component 300 is arranged between every two adjacent sliding components 100 to achieve the shielding of the foundation pit 200, thereby avoiding the pollution of operations and surrounding areas by dust, smoke, noise, etc. during the construction process, ensuring the air quality and environment of the local area and the normal life of surrounding residents. The top of the opening and closing component 300 is higher than the top of the sliding component 100 and the bottom thereof is at a preset distance from the top surface in the width direction of the foundation pit 200. The opposite sides of the opening and closing component 300 are respectively slidably connected and fixedly connected to two adjacent sliding components 100, and the bottom of each sliding component 100 is slidably connected to both sides in the width direction of the foundation pit 200 and can slide along the length direction of the foundation pit 200. Therefore, by sliding the sliding components 100 along the length direction of the foundation pit 200 on both sides in the width direction of the foundation pit 200, the opening and closing component 300 can slide on the sliding component 100 adjacent to and slidably connected thereto and overlap with the sliding component 100, thereby realizing the opening of the floor-mounted slidable opening and closing large-span space curved surface structure and the opening of the top of the foundation pit 200 corresponding to the sliding component 100. The open area of the foundation pit 200 can utilize an external tower crane to solve the problem of vertical transportation at the construction site, thereby realizing the all-weather construction operation of the foundation pit 200. In addition, by sliding the sliding components 100 along the length direction of the foundation pit 200 on both sides in the width direction of the foundation pit 200 in the direction opposite to the opening direction of the floor-mounted slidable opening and closing large-span space curved surface structure, the overlapping opening and closing component 300 and the sliding component 100 can be separated, thereby realizing the closing of the floor-mounted slidable opening and closing large-span space curved surface structure and the shielding of the top of the foundation pit 200 corresponding to the sliding component 100. Its overall structure is simple, can realize factory production and on-site assembly, etc., and can be applied to underground projects such as building construction and subway sections, so it has good application value and market prospects.

[0046] In some embodiments, referring to Figures 1 to 7 , each sliding component 100 in the present application includes an arc-shaped support grid 101 and a first flexible membrane layer 102; specifically, the support grid 101 is arranged across both sides in the width direction of the foundation pit 200, and the bottom of the support grid 101 is slidably connected to both sides in the width direction of the foundation pit 200 and can slide along the length direction of the foundation pit 200; thereby realizing the shielding and opening of the foundation pit 200.

[0047] The first flexible membrane layer 102 is disposed on the support grid 101 for shielding the support grid 101. Among them, the first flexible membrane layer 202 can be fixedly connected to the support grid 101 through embedded connection (that is, notches or channels are provided on the support grid 101, and the edge of the first flexible membrane layer 102 is embedded into the notches or channels of the support grid 101, and then fixed by means of bolts or clamps, etc.), cable connection (the edge of the first flexible membrane layer 102 is connected to the support grid 101 through connecting members such as ropes or steel cables, and this connection method can make the first flexible membrane layer 102 have better stretchability and adaptability), tension connection (the edge of the first flexible membrane layer 102 is connected to the support grid 101 through a tension device, and the tension device usually consists of a tension rod, a tension bolt and a tension rope, etc., and the flatness and tightness of the first flexible membrane layer 102 can be maintained by adjusting the tension), zipper connection (the edge of the first flexible membrane layer 102 may be connected to the support grid 101 by a zipper connection method, and the first flexible membrane layer 102 is fixed or released by opening and closing the zipper, which is convenient for replacement or maintenance), etc., so as to realize the shielding of the support grid 101 by the first flexible membrane layer 102. In addition, the connection method between the first flexible membrane layer 102 and the support grid 101 not only ensures the firm connection between the first flexible membrane layer 102 and the support grid 101, but also takes into account the ductility of the first flexible membrane layer 102 and the stability of the support grid 101.

[0048] In some embodiments, referring to Figures 1 to 7 , each opening and closing assembly 300 in the present application includes an arc-shaped support frame 301 and a second flexible membrane layer 302; specifically, the top of the support frame 301 is higher than the top of the support grid 101 and the bottom of it is a preset distance from the top surface in the width direction of the foundation pit 200 (wherein, the value of the preset distance can be set according to actual needs, and the purpose is to ensure that the bottom of the opening and closing assembly 300 does not contact the top surfaces on both sides in the width direction of the foundation pit 200, so the present application does not make specific limitations on it here), and the opposite sides of each support frame 301 are respectively slidably connected and fixedly connected to two adjacent support grids 101; among them, the sliding of the support grid 101 realizes the sliding of the support frame 301 on the adjacent support grid 101 that is slidably connected thereto, so as to realize the opening and closing of the large-span spatial curved surface structure with a floor that can slide open and close.

[0049] The second flexible film layer 302 is disposed on the support framework 301 for shielding the support framework 301. Among them, the second flexible film layer 302 can be fixed to the support framework 301 by means of embedded connection, cable connection, tension connection, zipper connection, etc., so as to realize the shielding of the support framework 301 by the second flexible film layer 302. In addition, the connection method of the second flexible film layer 302 and the support framework 301 not only ensures the firm connection between the second flexible film layer 302 and the support framework 301, but also takes into account the ductility of the second flexible film layer 302 and the stability of the support framework 301.

[0050] In some embodiments, referring to Figures 7 to 15 , the width of the support grid 101 in this application is greater than or equal to the width of the support framework 301. Among them, the top of the support framework 301 is higher than the top of the support grid 101 and there is a certain height difference between the bottom of the support framework 301 and the bottom of the support grid 101. That is to say, in the floor-mounted slidable openable and closable large-span space curved surface structure in this application, every two adjacent support grids 101 erect the support framework 301 therebetween, and during the sliding process of the support grid 101 fixedly connected to the support framework 301, it drives the support framework 301 to slide on the support grid 101 slidably connected to the support framework 301. The limitation of the widths of the support grid 101 and the support framework 301 in the above embodiments ensures that the entire support framework 301 can be completely located above the support grid 101, making the entire floor-mounted slidable openable and closable large-span space curved surface structure relatively stable.

[0051] In some embodiments, referring to Figures 2 to 4 , a chute 1011 is provided on the support grid 101 in this application, and a slider 3011 matching the chute 1011 is provided on the support framework 301. The slider 3011 is embedded in the chute 1011 and can slide along the length direction of the chute 1011. Among them, the length direction of the chute 1011 extends along the width direction of the support grid 101. To ensure the stability of the connection between the support grid 101 and the support framework 301, there can be multiple chutes 1011 on the support grid 101, and multiple sliders 3011 are provided on the support framework 301, and the multiple sliders 3011 correspond to the multiple chutes 1011 one by one.

[0052] In the above embodiments, during the sliding process of the support grid 101 that is fixedly connected to the support framework 301, the support framework 301 slides and overlaps on the support grid 101 that is slidably connected thereto, realizing the opening of the floor-slidable open-close large-span space curved surface structure and the opening of the top of the foundation pit 200, which is convenient for vertical transportation. On the contrary, during the sliding process of the support grid 101 that is fixedly connected to the support framework 301 in the direction opposite to the opening direction of the floor-slidable open-close large-span space curved surface structure, the support grid 101 is separated from the support framework 301 that overlaps therewith, realizing the closing of the floor-slidable open-close large-span space curved surface structure and the shielding of the top of the foundation pit 200, thereby avoiding the pollution of operations and surrounding areas by dust, smoke, noise, etc. during the construction process, and ensuring the air quality and environment of the local area and the normal life of the surrounding residents. In some embodiments, the length of the chute 1011 in the present application is less than or equal to the width of the support grid 101 and greater than or equal to the width of the support framework 301. In this way, during the sliding process of the support grid 101 that is fixedly connected to the support framework 301, the support framework 301 slides in the chute 1011 of the support grid 101 that is adjacent to and slidably connected thereto. When the two support grids 101 are close to each other, the entire support framework 301 is located above the support grid 101 that is slidably connected thereto, enabling the support framework 301 to have a sufficient sliding distance.

[0053] In some embodiments, referring to Figure 6 , on both sides in the width direction of the foundation pit 200 in the present application, slide rails 201 are provided, and at the bottom of the support grid 101, pulleys 1012 that match the slide rails 201 are provided. The pulleys 1012 can slide along the length direction of the slide rails 201. Among them, the slide rails 201 are fixed on both sides in the width direction of the foundation pit 200 through anchor bolts, etc., and the pulleys can be driven by a motor, so as to realize the convenience of sliding of the support grid 101.

[0054] In some embodiments, both the support grid 101 and the support framework 301 in the present application are made of stainless steel. Among them, stainless steel is defined in accordance with GB / T 20878-2007 as steel with the main characteristics of being stainless and corrosion-resistant, and with a chromium content of at least 10.5% and a maximum carbon content not exceeding 1.2%. Stainless steel is the abbreviation of stainless acid-resistant steel. Steels that are resistant to weak corrosive media such as air, steam, and water or have stainless properties are called stainless steels. Stainless steels can be divided into martensitic steels, ferritic steels, austenitic steels, austenitic-ferritic (duplex) stainless steels, and precipitation-hardening stainless steels, etc. The purpose of using stainless steel for the support grid and the support framework is to enhance the strength and service life of the support grid and the support framework. That is, the specific type of stainless steel for the support grid and the support framework can be set according to actual needs. Therefore, the present application does not make specific limitations thereto herein.

[0055] Both the first flexible film layer 102 and the second flexible film layer 302 are made of polyethylene or polyvinyl chloride. The first flexible film layer 102 and the second flexible film layer 302 made of the above materials have flexibility, durability and heat resistance, and the first flexible film layer 102 and the second flexible film layer 302 made of polyethylene or polyvinyl chloride can be processed such as folded, cut, pasted, etc. as needed, and are applicable to products of various shapes and sizes, improving the wide applicability of the first flexible film layer 102 and the second flexible film layer 302; and they can be recycled to reduce the impact on the environment.

[0056] Further, the present application provides an installation method for a floor-mounted slidable open-close large-span space curved surface structure as follows:

[0057] S401. Determine the span and width of the support grid 101 and the width of the support framework 301 according to the width of the foundation pit 200. Among them, the span of the support grid 101 is L, its width is S, and the width of the support framework 301 is W, and W ≤ S.

[0058] S402. Install pulleys 1012 at the bottom of each support grid 101, and install a chute 1011 and the first flexible film layer 102 thereon.

[0059] S403. Install sliders 3011 matching the chutes 1011 on each support framework 301, and install the second flexible film layer 302 thereon.

[0060] S404. Set slide rails 201 along the length direction on both sides in the width direction of the foundation pit 200, and span multiple support grids 101 equidistantly across the foundation pit 200, so that the pulleys 1012 at the bottom of each support grid 101 slide in the slide rails 201.

[0061] S405. Set a support framework 301 between every two adjacent support grids 101, and the relative two sides of the support framework 301 are respectively slidably connected and fixedly connected to the two adjacent support grids 101, thereby realizing the installation of the floor-mounted slidable open-close large-span space curved surface structure.

[0062] The overall structure of the above floor-mounted slidable open-close large-span space curved surface structure is simple, and it can realize factory production and on-site assembly, etc., and can be applied to underground projects such as building construction and subway sections, so it has good application value and market prospects.

[0063] Reference Figures 8 to 15 , the present application provides a very specific usage method for a floor-mounted slidable open-close large-span space curved surface structure as follows:

[0064] S501. For the floor-mounted slidable openable and closable large-span space curved surface structure in a fully closed state, according to the open space required at the top of the foundation pit 200 at the construction site, move the support grid 101 on one side adjacent to the opening direction in the length direction of the slide rail 201 of the floor-mounted slidable openable and closable large-span space curved surface structure, so that the slider 3011 on the support framework 301 slides in the chute 1011 on the support grid 101 adjacent to it and slidably connected to it.

[0065] S502. When the slider 3011 on the support framework 301 slides in the chute 1011 on the support grid 101 adjacent to it and slidably connected to it and the sliding distance is S, the support framework 301 completely overlaps with the support grid 101 adjacent to it and slidably connected to it. Repeat the opening process of the floor-mounted slidable openable and closable large-span space curved surface structure in sequence until the open space at the top of the foundation pit 200 meets the requirements of the construction site, thus realizing the opening of the floor-mounted slidable openable and closable large-span space curved surface structure.

[0066] S503. When closing the floor-mounted slidable openable and closable large-span space curved surface structure in an open state, move the support framework 301 on one side adjacent to the opening direction of the floor-mounted slidable openable and closable large-span space curved surface structure in the direction opposite to its opening direction.

[0067] S504. When the support framework 301 moves in the direction opposite to its opening direction and the moving distance is W, the part where the support framework 301 completely overlaps with the support grid 101 separates. Repeat the above-mentioned closing process of the floor-mounted slidable openable and closable large-span space curved surface structure until the open space at the top of the foundation pit 200 is completely blocked, thus realizing the closing of the floor-mounted slidable openable and closable large-span space curved surface structure.

[0068] S505. By sliding the sliding component 100 along the length direction of the foundation pit 200 on both sides in the width direction of the foundation pit 200, the opening and closing component 300 can slide on the adjacent sliding component 100 that is slidably connected thereto and overlap with the sliding component 100, so as to realize the opening of the floor-slidable open-close large-span spatial curved surface structure and the opening of the top of the foundation pit 200 corresponding to the sliding component 100. The open area of the foundation pit 200 can utilize an external tower crane to solve the problem of vertical transportation at the construction site, thereby realizing the all-weather construction operation of the foundation pit 200. In addition, by sliding the sliding component 100 along the length direction of the foundation pit 200 on both sides in the width direction of the foundation pit 200 in the direction opposite to the opening direction of the floor-slidable open-close large-span spatial curved surface structure, the overlapping opening and closing component 300 and the sliding component 100 can be separated, so as to realize the closing of the floor-slidable open-close large-span spatial curved surface structure and the shielding of the top of the foundation pit 200 corresponding to the sliding component 100. Its overall structure is simple, and it can realize factory production and on-site assembly, etc., and can be applied to underground projects such as building construction and subway sections, so it has good application value and market prospects.
