[0026] Embodiment

[0027] Please refer to Figure 1 , the present utility model provides an integrally assembled elevator corridor structure 100, which includes two symmetrically arranged L-shaped precast beams 1. There are multiple precast floor slabs 2 between the two L-shaped precast beams 1, and multiple precast guardrail plates 3 are provided on each L-shaped precast beam 1. After the L-shaped precast beam 1, precast floor slab 2 and precast guardrail plate 3 are assembled, secondary grouting is carried out at all connection parts to form an integral body.

[0028] More specifically, please refer to Figure 2, Figure 3 , Figure 5 and Figure 7 , the L-shaped precast beam 1 includes a base body 11, a high end face 12 and a low end face 13 are formed on the base body 11, a plurality of ribbed steel bars 14 are provided on the high end face 12, and beam stirrups 15 are provided between the high end face 12 and the low end face 13. The precast floor slab 2 includes precast slab steel bars 21, and the precast slab steel bars 21 are fixed to the beam stirrups 15. Among them, the L-shaped precast beam 1 is precast in a factory, the low end face 13 of the L-shaped precast beam 1 is used to bear the precast floor slab 2, and the high end face 12 of the L-shaped precast beam 1 is used to bear the precast guardrail plate 3; the beam stirrups 15 of the L-shaped precast beam 1 are exposed, and ribbed steel bars 14 are embedded in the beam. A grouting connection part 4 is provided between the precast slab steel bars 21 and the beam stirrups 15.

[0029] More specifically, when the precast floor slab 2 and the L-shaped precast beam 1 are hoisted on site, the precast floor slab 2 is erected on the L-shaped precast beam 1, and the precast slab steel bars 21 and the beam stirrups 15 are arranged closely; the next precast floor slab 2 is hoisted and placed, the precast slab steel bars 21 and the beam stirrups 15 are arranged closely, and at the same time, the precast slab steel bars 21 of this precast floor slab 2 and the precast slab steel bars 21 of the previous precast floor slab 2 are arranged closely, and so on. Compared with the laminated floor slabs used in the current market, the precast floor slab 2 is only provided with precast slab steel bars 21. After the on-site hoisting is completed, the grouting connection part 4 for pouring concrete is required. It can not only maintain the same thickness as the cast-in-place floor slab, but also greatly reduce the on-site workload and the construction speed is fast. At the same time, the precast slab steel bars 21 and the beam stirrups 15, as well as between adjacent precast slab steel bars 21, are fixed by binding, with small workload and high work efficiency. When the splicing of the precast floor slab 2 is completed, an installation working surface is provided, and the installation of the scaffold is omitted.

[0030] More specifically, please refer to Figure 4 , Figure 5 and Figure 7 , a plurality of corrugated pipes 31 are provided on the precast guardrail plate 3 along the vertical direction, a plug post 32 and a plug slot 33 are respectively provided on both sides of the precast guardrail plate 3 along the vertical direction, and in any two adjacent precast guardrail plates 3, the plug post 32 of one precast guardrail plate 3 is inserted into the plug slot 33 of the adjacent another precast guardrail plate 3, and the ribbed steel bar 14 is inserted into the corrugated pipe 31. Among them, the number of the plug post 32 and the plug slot 33 is not limited to one, and can also be multiple. The number of the plug post 32 and the plug slot 33 in each precast guardrail plate 3 can be the same or different, as long as the splicing of two adjacent precast guardrail plates 3 can be successfully completed. Grouting connection parts 4 are provided between the ribbed steel bar 14 and the corrugated pipe 31, and between the precast guardrail plate 3 and the high end face 12. Preferably, the corrugated pipe 31 is a metal corrugated pipe. The corrugated pipe 31 extends along the vertical direction to the upper and lower ends of the precast guardrail plate 3.

[0031] Among them, the precast guardrail panel 3 is precast in the factory. The cooperation between the insertion column 32 and the insertion groove 33 is similar to the mortise and tenon structure. Two adjacent precast guardrail panels 3 can be spliced in a sheet-like manner, which is simple and efficient. When formwork is set for the precast guardrail panel 3, the corrugated pipe 31 is buried in the steel reinforcement cage. Both ends of the corrugated pipe 31 are blocked to prevent concrete from flowing in. Due to the spiral raised texture of the corrugated pipe 31, the bite force or bonding force between the corrugated pipe 31 and the grouting connection part 4 can be increased.

[0032] More specifically, please refer to Figure 4 , a pressing top 34 is integrally formed at the top end of the precast guardrail panel 3, and the corrugated pipe 31 extends to the upper end surface of the pressing top 34. The pressing top 34 is arranged together at the top end of the precast guardrail panel 3 and integrally formed after integration. Different from the prior art, the brick-built guardrail panel still needs to additionally set a coping on site. The process is simple.

[0033] More specifically, please refer to Figure 6 and Figure 7 , a cushion block 5 is arranged between the precast guardrail panel 3 and the high-end surface 12. The height of the cushion block 5 is lower than the height of the grouting connection part 4 between the precast guardrail panel 3 and the high-end surface 12. Preferably, the cushion block 5 is an elastic block. The elastic cushion block 5 plays a shock-absorbing role during the installation process of the precast guardrail panel 3 and the high-end surface 12, avoiding the disadvantage of easy hard impact when the two are installed, and can also play a role in limiting the position.

[0034] More specifically, please refer to Figure 6 , threaded parts 141 are provided at both ends of the ribbed steel bar 14. A steel bar connecting sleeve 6 is arranged between two ribbed steel bars 14 connected up and down. The steel bar connecting sleeve 6 is set into the threaded part 141 to connect and fix the two ribbed steel bars 14.

[0035] When the precast guardrail panel 3 and the L-shaped precast beam 1 are hoisted on site, after the precast floor slab 2 is assembled, personnel can stand on the precast floor slab 2 to work. Screw the steel bar connecting sleeve into the upper end of the ribbed steel bar 14 of the L-shaped precast beam 1, and then screw it into the ribbed steel bar 14 connected thereto. This steel bar is lower than the upper end surface of the guardrail. Place the cushion block 5 on the high-end surface 12 of the L-shaped precast beam 1, and pour a layer of slightly expanding cement mortar, that is, the grouting connection part 4. The layer thickness of the grouting connection part 4 is slightly higher than that of the cushion block 5; align and lower the precast guardrail panel 3. The precast floor slab 2 can be used to provide temporary support for the precast guardrail panel 3, and then align and place the next precast guardrail panel 3. Splice and install them in this way in turn. The precast guardrail panels 3 are connected by a mortise and tenon structure, so that the precast guardrail panels 3 can form a whole.

[0036] After the L-shaped precast beam 1, precast floor slab 2 and precast guardrail plate 3 of the utility model are assembled, secondary grouting is carried out at all joints to form a grouting connection part 4, so that the L-shaped precast beam 1, precast floor slab 2 and precast guardrail plate 3 form an integral body, which can not only maintain the same thickness as the cast-in-place slab, but also greatly reduce the workload on site; the precast guardrail plates 3 are quickly connected through the mortise and tenon structure of the insertion column 32 and the insertion groove 33, so that a plurality of precast guardrail plates 3 can form an integral body; in the utility model, the precast floor slab 2 and the precast guardrail plate 3 are spliced in sheets, the process is simple, and the construction speed is fast.

[0037] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0038] The above-described embodiments only represent several implementation manners of the utility model, and the description thereof is relatively specific and detailed, but it should not be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several deformations and improvements can be made, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
