[0038] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this invention, the invention will be further described below in conjunction with specific illustrations.

[0039] like Figures 1-5 As shown, the integrated cast-in-place construction equipment for the inclined wall and stairs includes several staircase casting boxes and inclined wall baffles 30.

[0040] The inclined wall and the stairs are integrally casted by the construction method, and the construction method comprises

[0041] Firstly, the inclined wall baffle 30 is erected side by side at the inclined wall construction position, the end of the inclined wall baffle 30 is inserted into the ground and fixedly connected with the ground, the two inclined wall baffles 30 are shielded in the horizontal direction by the baffles, and the space between the two inclined wall baffles 30 is the inclined wall casting space, wherein the side inclined wall baffle 30 of the construction stairs is provided with a prefabricated concrete wall plate. Then, when the first stair casting box is installed, a plurality of main connecting steel bars 31 are inserted horizontally into the inclined wall baffle 30, the main connecting steel bars 31 are prefabricated on the inclined wall baffle 30 when the prefabricated concrete wall is used, the main connecting steel bars 31 are rigidly fixedly connected with the inclined wall baffle 30, one end of the main connecting steel bars 31 extends to the inclined wall casting space, and the other end of the main connecting steel bars 31 extends away from the inclined wall baffle 30 and is used for cooperating with the stair casting box.

[0042] The installation process of the stair casting box is as follows: firstly, the two side baffles 10 are arranged side by side, the front baffle 11 is fixedly installed at one end of the two side baffles 10 by bolts or screws, and the rear connecting plate 13 is fixedly installed at the other end of the two side baffles 10 by bolts or screws, so that the two side baffles 10, the front baffle 11 and the rear connecting plate 13 form a rectangular frame structure. Then, the reserved holes 21 on the two side baffles 10 of the rectangular frame structure are aligned with the end of the main connecting steel bars 31, the reserved holes 21 are arranged on the side baffles 10, and the reserved holes 21 are arranged at equal intervals along the extension direction of the side baffles 10. The side baffles 10 are installed through the end of the main connecting steel bars 31 away from the inclined wall baffle 30, so that the side baffles 10 abut against the inclined wall baffle 30. Then, the stair upper formwork 12 is fixedly installed on the upper side of the rectangular frame structure, the stair upper formwork 12 is arranged on the side baffles 10, the side baffles 10 and the stair upper formwork 12 are fixedly connected by bolts or screws, and the stair lower formwork 16 is fixedly installed on the lower side of the rectangular frame structure, the stair lower formwork 16 abuts against the lower end of the side baffles 10, and the stair lower formwork 16 and the side baffles 10 are fixedly connected by bolts or screws, so that the stair upper formwork 12, the stair lower formwork 16 and the rectangular frame structure form the stair casting box.

[0043] In the installation of the second stair pouring box, the two stair pouring boxes are spliced, a plurality of stair pouring boxes are arranged side by side along the horizontal extension direction of the inclined wall baffle 30, and the front baffle 11 and the rear connecting plate 13 on the adjacent stair pouring boxes are assembled and fixed. The rear connecting plate 13 is provided with a connecting clamping groove 15, the inner contour of the connecting clamping groove 15 is matched with the outer contour of the end of the front baffle 11 away from the stair upper formwork 12, and the front baffle 11 and the rear connecting plate 13 are fixed after the mortise and tenon connection of the front baffle 11 and the connecting clamping groove 15. After assembly, the main connecting steel bars 31 are inserted into the inclined wall baffle 30. When the inclined wall baffle 30 is a prefabricated concrete wall plate, the main connecting steel bars 31 are inserted into the through holes reserved in the inclined wall baffle 30, and then the connection state of the stair pouring box in S2 and the main connecting steel bars 31 is formed. The connecting clamping groove 15 provided with the connecting clamping groove 15 is inserted into the connecting part of the rear connecting plate 13 and the stair upper formwork 12, the connecting clamping groove 15 and the stair pouring box form a stair pouring cavity 40, and the splicing joint is sealed by sealing material, so that the stair pouring cavity 40 remains in a closed state.

[0044] Finally, the concrete mortar is poured into the grouting holes 20 on the upper end of the inclined wall baffle 30 and the stair upper formwork 12. The grouting holes 20 are arranged at the upper end of the stair upper formwork 12 in the installed position, and two grouting holes 20 are arranged on both sides of the stair upper formwork 12 in the extension direction of the inclined wall baffle 30. The concrete mortar fully fills the stair pouring cavity 40 and the inclined wall pouring space, and forms a poured stair 42 and a poured wall 41 respectively.

[0045] After pouring, the bolts or screws for fixedly connecting the stair upper formwork 12 and the stair lower formwork 16 with the side baffle 10 are disassembled, and then the side baffle 10 is disconnected from the stair upper formwork 12 and the stair lower formwork 16 by using a hard object such as a crowbar, so that the stair upper formwork 12 and the stair lower formwork 16 are disassembled, and the inclined wall baffle 30 away from the side baffle 10 is also disassembled. At this time, the poured wall 41 can be used independently.

[0046] The joint between the connecting clamping groove 15 and the front baffle 11 is filled with grouting mortar or adhesive to further improve the structural strength of the joint. After the stair upper formwork 12 and the stair lower formwork 16 are disassembled, the length of the end of the front baffle 11 and the rear connecting plate 13 away from the inclined wall baffle 30 is greater than that of the poured stair 42. At this time, a falling prevention net can be fixed between the front baffle 11 and the rear connecting plate 13 by using fasteners such as bolts and screws or welding, so as to avoid falling from the side away from the poured wall 41 when a person walks on the poured stair 42.

[0047] The observation passage is communicated with the stair pouring cavity 40 and is provided with a transparent observation plate 22. The pouring condition in the stair pouring cavity 40 can be directly observed through the transparent observation plate 22. Since the inner side of the stair upper formwork 12 is arranged in a stair shape, cavities are likely to be formed at the inner side of the stair upper formwork 12 in a stair shape during the pouring process. At this time, the transparent observation plate 22 can be used to observe whether cavities are formed. If cavities are formed, the transparent observation plate 22 is removed after the pouring is completed, and the cavities are manually filled, which is beneficial to improving the pouring quality of the stair.

[0048] The rear baffle 14 is provided with a reserved slot 32 with an opening facing the stair pouring cavity 40. A reinforcing steel bar 33 is inserted into the reserved slot 32. The other end of the reinforcing steel bar 33 extends through the stair pouring cavity 40 and is fixedly connected with the front baffle 11. The second support plate 24 is fixedly arranged below the rear baffle 14, and the first support plate 23 is fixedly arranged below the rear connecting plate 13. The second support plate 24 fixed below the rear baffle 14 and the first support plate 23 fixed below the rear connecting plate 13 can provide pressure resistance for the stair pouring box, thereby improving the stability of the stair pouring box during the installation and construction process of the stair pouring box and the pouring process of the concrete mortar. After the concrete mortar is poured and solidified, the reinforcing steel bar 33 can improve the connection strength between the rear baffle 14 and the poured stair 42 and between the front baffle 11 and the poured stair 42, thereby greatly improving the load-bearing capacity of the completed stair.

[0049] After the inclined wall and the stair are poured and dried, a fence is fixedly arranged on the upper surface of the side baffle 10 near the inclined wall baffle 30 to protect the poured wall. The fence can be directly installed on the side baffle 10 without damaging the poured stair 42, thereby ensuring the structural integrity of the poured stair 42 and improving the structural strength of the poured stair 42 during use.

[0050] The inclined wall and the stair can be simultaneously poured in one pouring operation, and the inclined wall and the stair are integrally formed after the pouring is completed, thereby eliminating the need for separate construction of the inclined wall and the stair and greatly improving the construction efficiency. The reserved holes 21 are arranged at equal intervals, the main connecting steel bar 31 is arranged in alignment with the reserved holes 21 when the main connecting steel bar 31 is inserted into the inclined wall baffle 30, the rectangular frame structure is hoisted and inserted into the main connecting steel bar 31, and the main connecting steel bar 31 provides support for the rectangular frame structure, thereby facilitating the installation of the frame structure and reducing the installation difficulty during the construction process.

[0051] When the concrete mortar is injected, the injection is through one grouting hole 20, when the concrete in the stair pouring cavity 40 is full, the excess concrete mortar will overflow from another grouting hole 20, at this time, it can be considered that the stair pouring cavity 40 is full and the injection is stopped, and the air in the stair pouring cavity 40 can overflow through the grouting hole 20 during the injection, the purpose of exhausting is achieved, and the phenomenon of cavity after the concrete mortar is injected in the stair pouring cavity 40 is reduced.

[0052] The front baffle 11 is connected with the connecting clamping groove 15 through the mortise and tenon connection, and then the rear connecting plate 13 and the front baffle 11 are fixed, so that the relative movement of the rear connecting plate 13 and the front baffle 11 in the horizontal direction is limited, and under the restriction of gravity and the main connecting steel bars 31, it is ensured that the front baffle 11 will not move upward, thereby the stability of the multiple stair pouring box bodies after splicing is improved, and when the error after splicing of two stair pouring box bodies is too large or other special conditions occur, the stair pouring box bodies can also be vertically lifted for quick disassembly before the main connecting steel bars 31 are inserted into the reserved holes 21, and the convenience of construction is improved.

[0053] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
