Description

Technical Field

[0001] The utility model relates to the field of rail transit construction protection auxiliary components, in particular to a subway construction safety enclosure. Background Art

[0002] The subway is a form of urban public transportation. During the operation of the subway, in order to meet the transfer needs, new transfer channels need to be added, which requires the renovation of the side walls in the subway station. In order to ensure the normal operation of the opened subway, and according to the construction technology and requirements, the renovation area of ​​the station side wall needs to be fully enclosed by a fencing structure to meet the fire prevention, sound insulation, impact resistance and other performance requirements.

[0003] However, the current enclosure structure is usually constructed by splicing multiple rectangular vertical panels during specific layout. During installation, they are erected and unfolded, and the edges are fixed to the station structure layer panels by bolts. First of all, this layout method is very inconvenient to install, and it is not convenient to accurately limit the multiple vertical panels during the layout process. At the same time, the specifications of the vertical panels are usually fixed, which will result in a limited scope of application of the vertical panels. During the layout process, when it is necessary to fully enclose and shield the renovation area, it is often necessary to destroy and cut the vertical panels, resulting in a low reuse rate of the vertical panels.

[0038] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0039] See also Figure 1-Figure 11As shown, the utility model provides a subway construction safety enclosure, including a station structure top plate body 1 and a station structure bottom plate body 6, the bottom surface of the station structure top plate body 1 and the top surface of the station structure bottom plate body 6 are respectively fixed with a top seat 2 and a base 5 in the horizontal direction, and the top seat 2 and the base 5 are aligned vertically. A plurality of disassembly and assembly components 7 are installed on the lower part of the top seat 2 and the top of the base 5, and the parts of the disassembly and assembly components 7 at the upper and lower positions close to each other are vertically installed with closed enclosure components 3 in the horizontal direction, and the closed enclosure components 3 are detachably connected to the corresponding top seat 2 or base 5 through the disassembly and assembly components 7. Specifically, the disassembly and assembly components 7 include matching grooves 701 and matching seats 702, and the front of the top seat 2 and the base 5 are provided with a plurality of matching grooves 701 in the longitudinal direction, and the outer end surfaces of the matching grooves 701 at the upper and lower positions close to each other are open, and the matching grooves at the upper and lower positions are The front ends of the inner end surfaces 701 that are far away from each other are vertically provided with limiting holes 706, the number of the matching seats 702 corresponds to the matching grooves 701 and they are respectively slidably matched longitudinally, and the rear ends of the outer end surfaces of the matching seats 702 at the upper and lower positions that are close to each other are both vertically installed with closed enclosure components 3, and the front ends of the outer end surfaces of the matching seats 702 at the upper and lower positions that are close to each other are vertically provided with mounting holes 703, and the mounting holes 703 are respectively vertically coaxially matched with the corresponding limiting holes 706, and the mounting holes 703 are both slidably matched with limiting rods 707 along the vertical coaxial direction, and the limiting rods 707 at the upper and lower positions are slidably matched with each other. 07 The ends that are far away from each other are respectively matched with the corresponding limiting holes 706 for vertical sliding, and the limiting rods 707 at the upper and lower positions are close to each other and the ends that extend out of the outer end surface of the matching seat 702 are coaxially fixed with handles 705, and the part of the limiting rod 707 located between the corresponding handle 705 and the outer end surface of the matching seat 702 is matched with a spring 704 in a coaxial gap, and the two ends of the spring 704 are respectively fixedly connected with the corresponding handle 705 and the outer end surface of the matching seat 702. The purpose of this arrangement is to facilitate the longitudinal sliding cooperation and the limiting rod through the matching seat 702 and the matching groove 701 707 and the limiting hole 706 are matched by vertical sliding to fix the closed enclosure assembly 3 detachably on the corresponding bottom of the top seat 2 or the top of the base 5, so that the closed enclosure assembly 3 can be quickly assembled on the corresponding bottom of the top seat 2 or the top of the base 5 to complete the layout. At the same time, only the limiting rod 707 needs to be pulled out of the limiting hole 706 to make the matching seat 702 slide longitudinally out of the matching groove 701 to remove the closed enclosure assembly 3 from the corresponding bottom of the top seat 2 or the top of the base 5, so that the closed enclosure assembly 3 can be quickly removed from the corresponding bottom of the top seat 2 or the top of the base 5.

[0040] See also Figure 1-Figure 6As shown, the closed enclosure components 3 at the bottom of the top seat 2 and the top of the base 5 are arranged side by side in the horizontal direction, and the closed enclosure components 3 corresponding to the upper and lower positions are closed in comparison, and the closed enclosure components 3 adjacent to the two sides are in close contact with each other. Specifically, the closed enclosure components 3 include fixed enclosure panels 301 and movable enclosure panels 302, and the fixed enclosure panels 301 are fixed to the rear of the outer end surface of the corresponding matching seat 702 through wing panels 307, and the fixed enclosure panels 301 are arranged vertically in the horizontal direction, and the movable enclosure panels 302 are hollow panels, and the movable enclosure panels 302 are sleeved on the outer periphery of the corresponding fixed enclosure panels 301 in a vertical sliding manner. The fixed enclosure panels 301 at the bottom of the top seat 2 and the top of the base 5 are arranged side by side in the horizontal direction, and the movable enclosure panels 302 corresponding to the upper and lower positions are closed in comparison, and the movable enclosure panels 302 adjacent to the two sides are in close contact with each other, so as to ensure that the construction opening position between the station structure top plate body 1 and the station structure bottom plate body 6 can be blocked when the multiple closed enclosure components 3 are closed in comparison, thereby realizing the construction opening The locking nut 304 is coaxially engaged with the stud 305, and the movable enclosure 302 is adjusted to fit the upper and lower portions of the locking nut 304.

[0041] See also Figure 3-Figure 6As shown, the disassembly assembly component 7 is optimized as follows: the cross-sectional shapes of the matching seat 702 and the matching groove 701 along the horizontal vertical plane are both dovetail-shaped or I-shaped. The reason for this arrangement is that since the matching groove 701 is a dovetail-shaped groove or an I-shaped groove, the installation position of the closed enclosure component 3 can be accurately limited by the matching seat 702 sliding along the matching groove 701 in the longitudinal direction, so as to facilitate its rapid and accurate positioning and assembly at the bottom of the top seat 2 or the top of the base 5. At the same time, the optional matching grooves 701 are all blind grooves in the longitudinal direction and are opened from front to back, and the rear end of the matching seat 702 is in contact with the rear end of the corresponding matching groove 701. In this arrangement, when the matching seat 702 slides longitudinally along the matching groove 701, when the limiting rod 707 slides longitudinally with the matching seat 702 to the vertical coaxial comparison with the limiting hole 706 of the matching groove 701, the rear end of the matching seat 702 is in contact with the rear end of the corresponding matching groove 701, and an obvious prompt can be given.

[0042] See also Figure 1-Figure 6 As shown, the closed enclosure assembly 3 is optimized as follows: the adjustment grooves 303 are all vertically arranged waist-shaped long grooves, and the ends of the adjustment grooves 303 at the upper and lower positions that are away from each other are all open, so that the studs 305 can slide and disengage from the open ends of the corresponding adjustment grooves 303. Such an arrangement first facilitates the adjustment grooves 303 to have a sufficiently wide adjustment range so that the movable enclosure 302 can have a larger vertical telescopic adjustment space. At the same time, the design of one end of the adjustment groove 303 being open can also enable the studs 305 to slide and disengage from the open ends of the adjustment grooves 303, thereby enabling the movable enclosure 302 and the fixed enclosure 301 to be separated from each other, thereby facilitating the rapid combination and disassembly of the movable enclosure 302 and the fixed enclosure 301.

[0043] Further optionally, the outer end of the stud 305 is coaxially fixed with an end plate 306, and the locking nuts 304 are all hand-tightened knurled nuts. Since the outer end of the stud 305 is provided with the end plate 306, it is possible to prevent the locking nut 304 from accidentally detaching and being lost from the outer end of the stud 305. At the same time, since the locking nut 304 is a hand-tightened knurled nut, it is convenient to directly tighten or loosen the locking nut 304 by hand. Specifically speaking of the fixed enclosure 301 and the movable enclosure 302, both the fixed enclosure 301 and the movable enclosure 302 are rectangular plates, and the peripheries of the fixed enclosure 301 and the movable enclosure 302 do not interfere with the corresponding handle 705. Preferably, the wing plate 307 is welded and fixed to the corresponding end face of the fixed enclosure 301, and at the same time, the wing plate 307 is fixed to the outer end face of the corresponding matching seat 702 by adding screws. Such an arrangement first facilitates the rapid combination of the fixed enclosure 301 and the corresponding matching seat 702. At the same time, preferably, the peripheries of the fixed enclosure 301 and the movable enclosure 302 do not contact the periphery of the handle 705, so as to prevent the fixed enclosure 301 and the movable enclosure 302 from interfering with the smooth pulling of the handle 705.

[0044] See also Figure 1-Figure 2 As shown, the top seat 2 and the base 5 are optimized as follows: the top seat 2, the base 5, the station structure top plate body 1 and the station structure bottom plate body 6 are of equal length, and the outer end faces of the movable enclosures 302 on both sides are flush with the corresponding outer end faces of the top seat 2 and the base 5. The purpose of this arrangement is to ensure that the movable enclosures 302 on both sides can respectively close and cover the side positions of the construction opening. The four corners of the top seat 2 and the base 5 are horizontally extended and fixed with connecting plates 4, and the connecting plates 4 are provided with connecting holes 401 for inserting and installing bolts. This arrangement makes it easy for the top seat 2 and the base 5 to be fixed by installing bolts to the installation position through the connecting holes 401 of the connecting plates 4.

[0045] With the above structure, specifically in the process of laying out and using the closed enclosure assembly 3, since the top seat 2 and the base 5 are respectively fixed laterally on the bottom surface of the station structure top plate body 1 and the top surface of the station structure bottom plate body 6, and the top seat 2 and the base 5 are compared with each other up and down, and the top seat 2 and the base 5 are both installed with multiple disassembly and assembly components 7 and closed enclosure assemblies 3, then the closed enclosure assembly 3 of the top seat 2 and the base 5 is compared with each other up and down and closed, the safety enclosure protection of the station construction position can be successfully completed, and the enclosure construction layout method is simple and easy to operate. Specifically, in the combination of the closed enclosure assembly 3 with the top seat 2 or the base 5 through the disassembly and assembly assembly 7, at the beginning, the matching seat 702 and the matching groove 701 are longitudinally slidably matched, and the limit rod 707 and the limit When the locking cam 720 is in place, the locking cam 720 is in a position to move the locking cam 721 to a position adjacent to the locking cam 722. The locking cam 720 is in a position adjacent to the locking cam 722. When the locking cam 720 is in a position adjacent to the locking cam 722, the locking cam 720 is in a position adjacent to the locking cam 722. The locking cam 706 can be easily removed from the locking cam 708 by simply pulling the locking cam 707 out of the locking cam 708. Repeated use, and specifically in the process of closing the closed enclosure assembly 3 at the upper and lower positions, screw the locking nut 304, then the stud 305 slides vertically along the adjustment groove 303 and the locking nut 304 is tightened again to vertically telescope the movable enclosure 302, and then the length of the movable enclosure 302 exceeding the fixed enclosure 301 can be adjusted by vertical telescopic adjustment of the movable enclosure 302, so as to facilitate the adjustment of the movable enclosure 302 corresponding to the upper and lower positions to fit each other, ensuring that the corresponding closed enclosure assemblies 3 at the upper and lower positions can be completely aligned and closed without the need to damage and cut the closed enclosure assemblies 3, enriching the general use scope of the closed enclosure assembly 3 and improving the use flexibility of the closed enclosure assembly 3.

[0046] Preferably, when the closed enclosure assembly 3 is laid out, the end surface of the closed enclosure assembly 3 not provided with the adjustment groove 303 and the stud 305 should be arranged to face outward, so that the outward end surface of the closed enclosure assembly 3 is reasonably beautiful.

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
