Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of pouring bearing platform, more specifically, relates to a strip member concrete pouring auxiliary bearing platform in limited space and a construction method. BACKGROUND

[0002] After the main structure of the current construction project is completed, for the subsequent construction contents such as accessory decoration engineering, there may be a situation that low-height strip members on the bottom plate surface need to be poured again. The concrete quantity required by such members is small, the surface is wide, and the height is slightly higher than the ground. Since the pouring body is in a limited space, the concrete delivery pump truck and the mixer truck cannot enter, and only a small amount of entrance can be used as a concrete delivery point and a temporary stacking point. During construction, the tools such as the bucket car are used to transfer within the limited construction space. In the field construction, the conventional method is to use manual shoveling to pour at the pouring point, or to use a formwork and masonry or angle steel support to set up a temporary inclined platform for construction, and to connect with the ground in sequence, so as to drive the bucket car into the formwork to unload and pour. When pouring at the next point, the formwork and the lower cushion or support need to be transported again. Such methods are time-consuming and have a great impact on the workability of the concrete. When the pouring site is changed, the height of the member changes, the bottom support is already fixed in height, and cannot be adjusted again. If the rigidity of the formwork is insufficient or the formwork under the masonry cushion shifts during the construction process, it is easy to overturn and cause injury to the personnel. Therefore, it is of great significance to provide a safe, fast, and flexible height-adjustable strip member concrete pouring auxiliary bearing platform for pouring construction in limited space.

[0003] In order to solve the above technical problems, Chinese utility model patent CN201902023U discloses a combined steel structure unloading platform, which is characterized in that: the combined steel structure unloading platform comprises a platform component, a connecting component and a slope component; the platform component and the connecting component are connected by a connecting piece, and the connecting component and the slope component are connected by a connecting piece. The connecting piece comprises a steel lug plate and a steel pin, the steel lug plate is welded at the mutual connection part of the platform component, the connecting component and the slope component, a long strip-shaped hole is provided on the lug plate, and the steel pin is inserted into the long strip-shaped hole to connect the two steel plates. The utility model can increase the operability of concrete pouring to a certain extent and reduce the cost. The utility model reduces the fluidity requirement of pouring concrete, and can achieve the purpose of reducing the cost of pouring concrete by adjusting the concrete mix ratio. In addition, utility model patent CN217751992U discloses a parking device for pouring twist king block, which comprises a parking platform, one end of the parking platform is inclined downward to form a parking slope, the parking platform comprises a table top and a support frame, the table top is fixed to the top of the support frame, a plurality of anti-skid protrusions are uniformly arranged on the table top, and a plurality of movable rollers are arranged at the bottom of the support frame. One purpose of the utility model is to place the twist king block template at one end of the parking platform, and the concrete tank truck drives to the parking platform through the parking slope so that the pouring opening is aligned with the template pouring opening for pouring. The device has simple structure and can flexibly arrange the pouring position without fixed point construction, which helps to improve the construction efficiency.

[0004] In the prior art, there are still the following improvements: the currently used pouring auxiliary bearing platform fixed by the platform component, the connecting component and the slope component can realize temporary loading and unloading construction, but the height of the unloading platform cannot be adjusted, which is relatively limited in applicability, resulting in poor flexibility and unchanged use. Therefore, the existing scheme should be optimized from the perspective of adjustable support height; (2) When switching the construction point, since the connecting component has a relative positioning relationship with the ground, it is necessary to reassemble the already assembled temporary platform and reassemble the positioning at the new construction site. As can be seen, this method not only leads to low construction efficiency, but also inevitably consumes the fatigue strength of the parts when repeatedly disassembling and assembling, thereby affecting the safety of the support platform to a certain extent; (3) When pushing the feeding car to move upward along the slope, measures should be taken to prevent the feeding car from sliding downward, and in addition, the slope surface should be as large as possible to meet the construction needs of transporting most feeding cars and workers standing on both sides of the slope to assist the feeding car.

4. A construction method for an auxiliary support platform for concrete pouring of strip-shaped components in a confined space, applicable to the auxiliary support platform for concrete pouring of strip-shaped components in a confined space as described in claim 3, characterized in that... Includes the following steps: S100: According to the construction design requirements, after determining the location of the concrete to be poured, the carrying platform is moved to the first construction location by the moving unit, and the front end of the feeding inclined main board (4) is kept close to the strip component template (8) of the pouring area (9). Then, the walking wheel (200) is locked by stepping on the wheel locking component (210) to prevent the carrying platform from sliding horizontally. At this point, the position of the operating platform is fixed. S200: Based on the current height of the injection zone (9), the first adjustment telescopic rod (301) and the second adjustment telescopic rod (302) are adjusted by the height adjustment unit (3) to maintain the same feed amount, so that the feeding inclined plate (4) moves upward and the front end of the feeding inclined plate (4) reaches an appropriate height; S300: Based on the width of the feeding cart, adjust the overall width of the feeding ramp main board (4) through the main board expansion unit (5), and manually move up along the main board expansion unit (5) to assist in pushing the feeding cart forward; S400: Open the main board connecting unit (7). After the height of the front side of the feeding inclined main board (4) is adjusted, slide the connecting slide plate (802) out of the side slide groove (701) and connect it to the ground. S500: When the feeding car is pushed above the feeding anti-slip unit (6), the feeding anti-slip unit (6) is opened so that the feeding car can be stopped stably, and then the concrete slurry is poured into the grouting area (9). S600: After unloading, close the feeding anti-slip unit (6), push the feeding car down the feeding ramp main board (4), open the wheel locking assembly (210), allow the walking wheels (200) to move freely, and pull the carrying platform to the next construction site through the traction lock (123). Repeat the above process until all construction is completed.
