Description

Technical Field

[0001] The invention relates to the technical field of construction, and in particular to a foundation pit construction work platform device. Background Art

[0002] Construction projects in cities are affected by planning and surrounding buildings. The site red line is often close to the edge of the foundation pit. As a result, during the excavation of the foundation pit, the pit edge is available for earthwork vehicles to drive, and the excavator construction area is severely limited. If the project is close to the subway or other important buildings and other facilities that are sensitive to deformation, the routes of heavy-loaded vehicles such as earthwork vehicles must avoid their protection areas during the construction road planning process, and the construction site is further limited.

[0003] In order to solve the problem of limited construction sites for deep foundation pits, most projects often adopt the method of adding side trestles. However, the construction of side trestles requires a long maintenance period. In addition, they need to be demolished during the project backbuilding phase, which will generate a large amount of abandoned concrete construction waste, which is not in line with the concept of green construction and will also lead to a significant increase in construction costs. In terms of side trestle construction, the side trestles will occupy the upper space of the foundation pit, making the subsequent lifting of steel supports and materials such as steel bar formworks difficult, thus affecting the construction period of deep foundation pit excavation.

[0004] In order to shorten the construction period, adhere to the concept of green construction, reduce the generation of construction waste, and solve the problem of limited deep foundation pit construction sites, technical personnel in this field have been looking for solutions.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0050] In the invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to the specific circumstances.

[0051] Please refer to Figures 1 to 20The foundation pit construction work platform device includes: a pair of electric driving devices 3, a load-bearing beam 5 and a steel platform 4. The pair of electric driving devices 3 are respectively arranged on the retaining ring beams 2 on the opposite sides of the foundation pit, and can be moved along the retaining ring beams 2; the two ends of the load-bearing beam 5 are respectively connected to a pair of electric driving devices 3 (at this time: the load-bearing beam is in a state of spanning the foundation pit. That is: it does not occupy the roads around the foundation pit, but only occupies the space above the foundation pit.); the steel platform 4 is laid on the surface of the load-bearing beam 5 to carry construction machinery and equipment (including transportation equipment, lifting equipment, excavation equipment, etc.). In other words, with the working platform device of the present invention, there is no need to provide roads around the foundation pit. Construction machinery and equipment such as excavators and earthmoving vehicles can be parked on this working platform device. They do not need to walk by themselves, but through the position movement of the foundation pit construction work platform device (the platform device is driven by the electric driving device 3 to achieve position movement), the position of each construction machinery and equipment is adjusted relative to the position of the foundation pit, and the problem of limited construction site of deep foundation pits is effectively solved.

[0052] Please refer to Figure 4 and Figure 5 The retaining structure 1 is a bored cast-in-place pile or a ground wall, the retaining ring beam 2 is the upper structure of the retaining structure 1, and the electric driving device 3 is arranged on the retaining ring beam 2.

[0053] It can be understood that multiple foundation pit construction work platform devices can be set on the retaining ring beams on opposite sides of the foundation pit to meet the construction needs of different construction machinery and equipment.

[0054] Example 1: Figure 1 and Figure 2 As shown, two foundation pit construction work platform devices are arranged on the retaining ring beams on opposite sides of the foundation pit, one of which is used to carry the excavator and the other is used to carry the transport vehicle, so as to serve as a dedicated construction road for the transport vehicle. The positions of the two foundation pit construction work platform devices are adjusted according to their respective needs, mainly based on their respective pair of electric driving devices to achieve position movement.

[0055] The platform device of the present invention can be moved along the retaining ring beam, only occupying the space above the foundation pit, and can be adjusted as needed to make room for the space above the foundation pit, thereby avoiding spatial impact on subsequent construction (for example, lifting of steel supports, lifting of materials such as steel bar formwork, etc.), saving construction time, and effectively solving the problem of limited construction sites in deep foundation pits; compared with the traditional method of adding side trestles, it does not generate a large amount of waste concrete garbage, saves construction costs, and is conducive to green construction.

The gear rotates in a predetermined direction under the driving control of the driving and control module 503, and the first member 5011 and the second member 5012 move relative to each other under the meshing transmission of the gears. The telescopic bearing beam 50 can realize the free extension and contraction of the telescopic rod 501 under the driving of the driving gear 5013, so as to extend or shorten according to the demand, so that the width of the construction platform device can be extended or shortened according to the demand of the foundation pit, and the width of the bearing beam at different parts can be adjusted to realize walking on the upper part of the irregular foundation pit.

[0060] Preferably, each electric driving device 3 includes: a load detection device to monitor the load condition of the device in real time, and immediately alarm once the load exceeds the allowable value to ensure construction safety.

[0061] Please refer to Figures 7 to 9 , Fig.19 The steel platform 4 includes: a plurality of sub-steel components 40 spliced ​​along the length direction; wherein each sub-steel component 40 includes: a main body 401, two card slots 404, two connecting male heads 402 and two connecting female heads 403 adapted to the connecting male heads 402, all the card slots 404 are opened at the bottom of the main body, and their shapes are adapted to the sleeve 5014; the two connecting male heads 402 are respectively arranged on two adjacent sides of one main body; the two connecting female heads 403 are respectively arranged on the other adjacent sides of the main body.

[0062] During use, the multiple sub-steel components 40 in the steel platform 4 can be divided into two parts based on the connecting male head and the connecting female head according to the needs of the site, so as to facilitate the entry and exit of earth-moving vehicles.

[0063] All components (steel platform 4, load-bearing beam 5, electric driving device 3) of the foundation pit construction work platform device of the present invention are assembled in an assembled manner, which is convenient for installation and removal, and can be repeatedly used after removal, thereby reducing construction costs.

[0064] In addition, the load-bearing beam 5 and the steel platform 3 are both made of multiple sub-components.
