DETAILED DESCRIPTION

[0030] The following embodiments are provided to further explain and supplement the present invention and do not constitute any limitation to the present invention.

[0031] like Figures 1 to 8 As shown, the rigid structure curing pit of the utility model includes a curing pit main body 10 and an insulation board 20. Among them, the curing pit main body 10 is spliced ​​by steel structure, which can be assembled and disassembled on site. The insulation board 20 is used to be connected to the curing pit main body 10 to form a closed curing space 30. The insulation board 20 is connected to the curing pit main body 10 by fasteners, which can be assembled and disassembled on site. In this way, the components constituting the steel structure curing pit can be processed in advance in the factory and then transported to the site for assembly without on-site welding, thereby reducing the construction period and improving construction efficiency. In addition, it can also be convenient for disassembly and assembly.

[0032] Furthermore, the curing pit body 10 is provided with at least one curing unit space 11. When one or more curing unit spaces 11 are sealed and surrounded by the insulation board 20, a closed curing space 30 can be formed, which can be used for curing the prefabricated components 40.

[0033] In order to facilitate the placement of the prefabricated components 40, storage platforms 12 are provided in the curing unit space 11 at intervals in the height direction. The storage platforms 12 are used to horizontally place the prefabricated components 40 to be cured. The storage platforms 12 can support both ends of the prefabricated components 40, so that the prefabricated components 40 are placed in the curing space 30 at intervals, thereby facilitating the curing.

[0034] In order to facilitate the delivery of the prefabricated component 40 into the curing unit space 11 and to place it in the storage platform 12, a guide rail 50 is provided at the bottom of the curing unit space 11. The guide rail 50 is arranged in a horizontal direction and can be fixed on a foundation. The guide rail 50 is used for the transport equipment to travel. The guide rail 50 can be a known guide rail 50. In this embodiment, the guide rail 50 is a double guide rail, which is arranged in parallel and spaced apart in the curing unit space 11.

[0035] To adjust the temperature and humidity of the curing space 30, a steam delivery system 60 is provided inside the curing cellar main body 10. Steam outlets 61 are respectively provided inside the curing unit spaces 11. The steam outlets 61 are connected to the steam delivery system 60, so that the steam outlets 61 can independently or uniformly deliver steam to the curing space 30 to adjust the temperature and humidity.

[0036] Preferably, each steam outlet 61 can be controlled separately. In this way, the steam outlet 61 inside a specific curing unit space 11 can be opened as needed to spray steam into the curing unit space 11 to adjust the temperature and humidity.

[0037] The setting of the steam delivery system 60 can refer to the prior art, and its steam delivery pipes can be laid on the ground of each curing unit space 11.

[0038] To monitor the temperature inside the curing space 30, temperature sensors are provided on the curing cellar main body 10 and / or the insulation board 20. The temperature sensors are connected to a control system, and the control system is connected to the steam delivery system 60. By detecting the temperature inside the curing space 30 and then adjusting the steam delivery of the steam delivery system 60, the temperature and humidity of the curing space 30 can be adjusted to the required range, thereby providing a good curing environment for the curing of the precast components 40.

[0039] Furthermore, the curing cellar main body 10 includes a plurality of columns 13, a plurality of longitudinal beams 14, and a plurality of cross beams 15.

[0040] The columns 13 are vertically arranged and play a main supporting role. The columns 13 can be of a tubular structure. In this embodiment, the columns 13 are rectangular steel pipes, and a plurality of preset holes are provided at intervals on the side walls thereof and distributed in the height direction for connection with other components through fasteners.

[0041] At least two columns 13 are arranged at intervals in a first direction to form a column group 130. The number of columns 13 in the column group 130 can be set as needed. The distances between the columns 13 in the column group 130 can be the same or different. Preferably, the columns 13 are evenly spaced.

[0042] At least two sets of column groups 130 are arranged at intervals in the second direction. Both the first direction and the second direction are perpendicular to the column 13, and the first direction is perpendicular to the second direction. In this way, the curing unit space 11 can be formed between adjacent two sets of column groups 130. For the convenience of description, the number of the curing unit spaces 11 is denoted as M, and the number of the column groups 130 is denoted as N, then M = N - 1. For example, between two sets of column groups 130, one curing unit space 11 can be formed. Between three sets of column groups 130, two curing unit spaces 11 can be formed. Between four sets of column groups 130, three curing unit spaces 11 can be formed. And so on.

[0043] The curing unit space 11 is formed by the column groups 130 being spaced apart from each other. When the curing unit space 11 is sealed by the heat-insulating board 20, the curing unit space 11 forms a curing space 30. At this time, the precast member 40 can be cured therein.

[0044] The curing space 30 can be formed by one curing unit space 11 or by multiple curing unit spaces 11 being connected. The size of the curing space 30 depends on the installation position of the heat-insulating board 20.

[0045] The cross beam 15 is connected between the column groups 130 in the second direction. In the height direction of the column groups 130, several cross beams 15 are provided at intervals. The number of the cross beams 15 provided in the height direction can be set as required.

[0046] Furthermore, for the convenience of on-site assembly and disassembly, the cross beam 15 and the column 13 are connected by fasteners. Specifically, the cross beam 15 can be selected as a rectangular steel pipe, and first connecting plate parts 151 fixedly connected or integrally formed therewith are respectively provided at both ends thereof. When the cross beam 15 is connected between the columns 13 in the second direction, the first connecting plate parts 151 at both ends of the cross beam 15 are respectively attached to the side walls of the columns 13, and then the columns 13 and the first connecting plate parts 151 are connected together by fasteners (such as screws or bolts), so that the detachable connection between the columns 13 and the cross beam 15 can be realized.

[0047] The longitudinal beam 14 is connected above the column 13 in the first direction. The number of the longitudinal beams 14 can be set as required. In the height direction of the column groups 130, several longitudinal beams 14 are provided at intervals. The longitudinal beams 14 on adjacent two sets of column groups 130 are spaced opposite to each other, and then the storage platform 12 can be formed. The longitudinal beams 14 are provided at intervals in the height direction, which is beneficial to placing the precast member 40 in the height direction.

[0048] The longitudinal beam 14 can, on the one hand, strengthen the structural stability of the maintenance cellar main body 10, and on the other hand, be used to directly support the placement of the precast member 40, and it provides the storage platform 12. During maintenance, the two ends of the precast member 40 are respectively placed on the longitudinally spaced beams 14.

[0049] Further, for the convenience of on-site assembly and disassembly, brackets 16 are respectively provided on the side walls of the column group 130 facing each other. The brackets 16 are spaced along the height direction of the columns 13. The brackets 16 are detachably fixed to the side walls of the columns 13 by fasteners, and they are used to support the longitudinal beam 14. The longitudinal beam 14 is then detachably fixed to the brackets 16 by fasteners.

[0050] Further, the bracket 16 includes a support plate portion 161, a second connecting plate portion 162, and a support plate portion 163. The support plate portion 161 is perpendicularly connected to the second connecting plate portion 162 to form an L shape, and the support plate portion 163 is connected between the support plate portion 161 and the second connecting plate portion 162 to enhance the structural strength and stability of the bracket 16. During installation, the second connecting plate portion 162 of the bracket 16 is attached to the side wall of the column 13 and connected by fasteners (screws or bolts), and the support plate portion 161 is in a horizontal state and perpendicular to the side wall of the column 13, so as to support the longitudinal beam 14.

[0051] Further, the longitudinal beam 14 is selected as an L-shaped steel. During installation, it is placed on the bracket 16, with a part of it fitting to the support plate portion 161 and a part fitting to the side wall of the column 13, and then it is connected to the column 13 or the support plate portion 161 by fasteners (screws or bolts). Preferably, the longitudinal beam 14 is detachably connected to the column 13 by fasteners (screws or bolts).

[0052] To facilitate the adjustment of the size of the maintenance space 30, a thermal insulation board installation space 70 is formed between two adjacent columns 13 in the column group 130. The thermal insulation board 20 can be selectively installed in the thermal insulation board installation space 70 to adjust the size of the maintenance space 30. By adjusting the installation position of the thermal insulation board 20, the size of the maintenance space 30 can be adjusted.

[0053] Since the column 13 has a certain thickness, when longitudinally spaced beams 14 are respectively installed on opposite sides of the column 13, a space will be formed between the longitudinally spaced beams 14, and this space is the thermal insulation board installation space 70. When the thermal insulation board 20 is installed in the thermal insulation board installation space 70, it is installed in the space enclosed by the column 13 and the longitudinally spaced beam 14.

[0054] When it is necessary to adjust the installation position of the heat preservation board 20 and thus adjust the size of the curing space 30, the longitudinal beam 14 on one side of the column 13 can be removed first. Then, the heat preservation board 20 is installed into the heat preservation board installation space 70. After the heat preservation board 20 is fixed, the removed longitudinal beam 14 is installed on the column 13. In this way, the heat preservation board 20 can be installed between the columns 13 and between the longitudinal beams 14 to seal and isolate the adjacent curing unit spaces 11.

[0055] For the outermost columns 13, the heat preservation board 20 can be directly installed between the columns 13 because usually only one side of the outermost columns 13 is provided with longitudinal beams 14.

[0056] The heat preservation board 20 can be a well-known heat preservation board 20, which is detachably connected to the column 13 through fasteners (screws or bolts).

[0057] When installing the heat preservation board 20, sealant is applied at the joints according to well-known techniques.

[0058] For convenient access, a cellar door can be provided on the heat preservation board 20. The setting of the cellar door can refer to well-known techniques.

[0059] In this embodiment, a group of heat preservation boards 20 is provided at every other column group 130, so that every two curing unit spaces 11 form a curing space 30. Later, according to needs, the position of the internal heat preservation board 20 can be adjusted to adjust the size of the curing space 30 to meet the actual curing requirements.

[0060] Furthermore, the curing cellar main body 10 further includes a V-shaped top 17 and a top beam 18.

[0061] The V-shaped top 17 is in a V shape and is used as a roof support. The V-shaped top 17 is detachably connected between the tops of adjacent two column groups 130 through fasteners.

[0062] The top beam 18 is used to connect the V-shaped tops 17 to strengthen the strength of the roof structure. The top beam 18 is connected between the V-shaped tops 17 along the first direction through fasteners.

[0063] Both the V-shaped top 17 and the top beam 18 are detachably connected, so they can be easily disassembled and assembled on site.

[0064] Furthermore, the V-shaped top 17 includes two rod bodies that are obliquely connected to form a V shape. Third connecting plate parts 171 are respectively provided at the ends of the rod bodies. The third connecting plate parts 171 are placed in contact with the tops of the columns 13 and then connected to the columns 13 through fasteners (screws or bolts). In this way, the detachable connection between the V-shaped top 17 and the columns 13 can be achieved.

[0065] The rod body and the third connecting plate part 171 can be fixed by welding. Among them, the rod body can be selected as a rectangular steel pipe, and the third connecting plate part 171 can be selected as a steel plate.

[0066] Furthermore, to facilitate the detachable connection between the V-shaped top 17 and the top beam 18, a fourth connecting plate part 172 is provided inside the tip of the V-shaped top 17. The fourth connecting plate part 172 is welded to the V-shaped top 17. The top beam 18 is selected as a rectangular steel pipe, and fifth connecting plate parts 181 are welded to both ends thereof respectively. During installation, the fourth connecting plate part 172 and the fifth connecting plate part 181 are fitted, and then connected by fasteners such as screws or bolts, so as to realize the detachable connection between the top beam 18 and the V-shaped top 17.

[0067] Furthermore, the curing cellar main body 10 further includes a first guide rod 19. The first guide rod 19 is used to enhance the structural stability. The first guide rod 19 is connected between the cross beams 15 at the highest position along the first direction.

[0068] Furthermore, the first guide rod 19 is selected as a rectangular steel pipe, and a sixth connecting plate part 191 extending along the length direction and protruding from both sides is provided on one side thereof. The sixth connecting plate part 191 is fitted to the bottom of the cross beam 15, and then connected by fasteners (screws or bolts), so as to realize the detachable connection between the first guide rod 19 and the cross beam 15.

[0069] The heat preservation board 20 is detachably connected to the V-shaped top 17 through fasteners, so as to seal the top of the cellar main body 10.

[0070] Although the present utility model has been disclosed through the above embodiments, the scope of the present utility model is not limited thereto.
