Description

Technical Field

[0001] The present application relates to the field of elevators, and in particular to an elevator foundation pit structure. Background Art

[0002] Elevators are common equipment in our lives. The elevator shaft is the shaft where the elevator is installed in the building. The elevator shaft must be constructed before the elevator is installed. The elevator foundation pit is an indispensable process in the construction of the elevator shaft. The elevator foundation pit refers to the place where the elevator installs some components such as buffers. The traditional construction method is: foundation excavation, pile head treatment, foundation cushion, casting frame, backfilling, protective structure, foundation pit monitoring, and equipment installation.

[0003] Casting the frame is an important process in construction. Before casting the frame, the formwork must be supported and erected first, then installed, reinforced and corrected, and finally cast.

[0004] However, the construction methods and processes used to install elevator foundation pits in existing buildings are relatively traditional. In this traditional construction method, the cast frame needs to be made on-site, which makes the construction efficiency of the elevator foundation pit low and the construction period long.

The bottom panel, the first side panel and the second side panel are all steel plates, and then the bottom panel is fixed by a fixing assembly.

[0009] Furthermore, the fixing assembly includes four steel plugs fixed at the four corners of the bottom of the base plate, and the surfaces of the steel plugs are fixed with abutment plates.

[0010] By adopting the above technical solution, the bottom plate is fixed by inserting the steel plug into the bottom of the foundation pit, and at the same time the abutment plate abuts against the earth pit, so that a certain distance is maintained between the bottom plate and the earth pit.

[0011] Furthermore, an asphalt layer is fixed on the top of the bottom plate, an asphalt layer is fixed on one end of the two first side plates close to each other, and an asphalt layer is fixed on one side of the two second side plates close to each other.

[0012] By adopting the above technical solution, the asphalt layer can achieve a waterproofing effect.

[0013] Furthermore, a fixing frame is fixed to each of the ends of the two first side panels that are away from each other.

[0014] By adopting the above technical solution, the contact area between the foundation pit and the concrete during pouring can be increased through the fixing frame.

[0015] Furthermore, a circular hole is symmetrically configured at the top of the second side plate, a plurality of inclined holes are configured in the circular hole, and the plurality of inclined holes are all interconnected with the first T-shaped groove.

[0018] By adopting the above technical solution, the cement sand can be brought into contact with the inside of the second side plate through the L-shaped groove, thereby increasing the contact area between the second side plate and the cement sand.

[0019] Furthermore, both ends of the top of the bottom plate are constructed with limiting grooves, and limiting plates are fixed to the bottoms of the two first side plates, and the limiting plates are located in the limiting grooves.

[0020] By adopting the above technical solution, the second T-shaped block can be limited by the cooperation of the limiting groove and the limiting plate.

[0021] In summary, the present application includes at least one of the following beneficial effects:

[0022] 1. The second side panel is installed by cooperating with the second T-block and the second T-slot, and then the first side panel is installed by cooperating with the first T-block and the first T-slot.

At the same time, the second T-block is limited by cooperating with the limit groove and the limit plate to prevent the second T-block from sliding in the second T-slot.

[0023] 2. Mud and sand can be injected through the circular hole. The injected mud and sand flows into the inclined hole through the circular hole, and then flows into the first T-shaped groove and the L-shaped groove to fix the first side plate and the second side plate, thereby increasing the firmness of the foundation pit. At the same time, the asphalt layer can play a waterproof role and protect the electrical components inside the elevator shaft. BRIEF DESCRIPTION OF THE DRAWINGS

During installation, first install the second T-block 9 in the second T-slot, install the second side panel 3, and then install the first T-block 8 in the first T-slot 12, and install the first side panel 2, thereby achieving the advantages of simple operation and fast installation. The enclosed space is the installation space of the elevator shaft, which speeds up the construction efficiency and reduces the construction period. The bottom plate 1, the first side panel 2 and the second side panel 3 are all steel plates, and then the bottom plate 1 is fixed in the pit through the fixing assembly.

[0034] Reference Figure 1-2 The fixing assembly includes four steel plugs 6 fixed at the four corners of the bottom of the bottom plate 1, and the surface of the steel plugs 6 is fixed with a contact plate 7. The steel plugs 6 are inserted into the bottom of the foundation pit, and then the contact plate 7 contacts the soil pit, so that a certain distance is maintained between the bottom plate 1 and the bottom of the foundation pit, and concrete can be poured on the bottom of the bottom plate 1.

[0035] Reference Figure 1-2 An asphalt layer 4 is fixed on the top of the bottom plate 1, an asphalt layer 4 is fixed on the ends of the two first side plates 2 close to each other, and an asphalt layer 4 is fixed on the sides of the two second side plates 3 close to each other. The asphalt layer 4 can play a waterproof role and protect the electrical components inside the elevator shaft.

[0036] Reference Figure 1-2 , the ends of the two first side plates 2 that are away from each other are both fixed with a fixing frame 5. The fixing frame 5 can interfere with the soil pit, and the contact area between the foundation pit and the concrete is increased during pouring, making the pouring more firm.

[0037] Reference Figure 2 and Figure 4 The second side plate 3 has a circular hole 10 symmetrically formed on the top, and a plurality of inclined holes 11 are formed inside the circular hole 10, and the plurality of inclined holes 11 are interconnected with the first T-shaped groove 12.

At this time, the enclosed space is the installation space of the elevator shaft, which achieves the advantage of fast installation, speeds up the construction efficiency, and reduces the construction period. Then, the entire assembled structure is lifted by a crane. It is hoisted into the foundation pit, and then the steel plug 6 is inserted into the bottom of the foundation pit to fix the bottom plate 1, and then the abutment plate 7 abuts against the soil pit, so that a certain distance is maintained between the bottom plate 1 and the bottom of the foundation pit, and concrete can be poured between the bottom plate 1 and the bottom of the foundation pit, and then the mud and sand are injected into the circular hole 10, so that it flows into the inclined hole 11, and then flows into the first T-shaped groove 12 and the L-shaped groove 13, to fix the first side plate 2 and the second side plate 3, thereby increasing the firmness between the first side plate 2 and the second side plate 3, and at the same time the asphalt layer 4 can play a waterproof role to protect the electrical components inside the elevator shaft.
