Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and hydropower construction, in particular to a concrete slab pouring device for steep slopes. Background Technique

[0002] According to the traditional high-slope concrete pouring construction, on-site construction workers use an 80T truck crane to install glued laminated wood formwork and tie rods for material installation and formwork fixation. The construction efficiency is low and the risk is high, which will affect the construction progress and safety. Moreover, during the current slope concrete pouring, formwork installation and tie rod fixation construction, on-site construction workers do not have a construction operation platform and operating space, and the coordinated operation of each operator cannot be in place in time. In addition, the repeated utilization rate of the glued laminated wood formwork is relatively low. As the working surface of the slope concrete pouring rises, the handling of the formwork and steel bars becomes more and more troublesome, posing a certain threat to the life safety of construction workers. Therefore, when pouring concrete, due to the relatively thick concrete thickness and large pouring volume, the glued laminated wood formwork and tie rods have certain tension and safety uncertainties, which cannot meet the on-site construction progress, thus increasing the operation difficulty of construction workers and having an adverse impact on the entire project construction process. The construction quality and progress cannot be guaranteed. Therefore, how to make a concrete slab pouring device for steep slopes that can solve the problems of the existing technology has become a technical problem to be solved.

Specific embodiments

[0024] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0025] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the content disclosed below.

[0026] The following combines Figures 1 to 5 To further illustrate the technical solution of the present utility model.

[0027] The first embodiment is as Figures 1 to 5 Shown: A concrete panel pouring device for a steep slope includes: a pouring support, a lifting ring bracket 1 is provided at the top of the pouring support, a lifting ring 2 is provided on the lifting ring bracket 1, a manual hoist is provided on the lifting ring 2, a cable 3 is provided on the manual hoist, a sliding formwork 11 is provided inside the pouring support at the bottom of the cable 3, a plurality of groups of limiters 4 for limiting are respectively provided at intervals at both ends of the pouring support, and rollers 7 that can slide and abut against the pouring support are provided on the outer side of the sliding formwork 11.

[0028] The described casting support includes a framework formed by two cross beams 10 and two longitudinal side supports 12. In the middle of the framework, two groups of longitudinal middle supports 9 are respectively arranged at intervals. On the outer side of the middle of the framework, multiple groups of transverse hoops 8 are arranged at equal intervals. An installation hole is provided in the middle of the stopper 4. A limiting rod 5 is detachably arranged in the installation holes of multiple stoppers 4. The gap between the limiting rod 5 and the longitudinal side support 12 is set as a random formwork position 6. A side formwork 14 is detachably arranged in the random formwork position 6.

[0029] At both outer ends of the sliding formwork 11, L-shaped formwork pressing pieces 13 are respectively arranged. The outer sides of the formwork pressing pieces 13 can be slidably hung on the longitudinal side supports 12. The formwork pressing pieces 13 are detachably arranged with the sliding formwork 11 through bolts. There are three groups of the hanging ring supports 1, and the three groups of the hanging ring supports 1 are arranged at equal intervals at the top end of the casting support. The material of the casting support is 10# channel steel, and the size of the hanging ring support 1 is 30 cm × 30 cm. There are three groups of the transverse hoops 8. The material of the sliding formwork 11 is steel. The material of the cable 3 is a steel wire rope with a diameter of 1 cm. The material of the limiting rod 5 is a steel pipe of A48.

[0030] The hand-pulled hoist hanging rings 2 are arranged on the top hanging ring supports 1, serving as the fixed positions for the hand-pulled hoist. The cable 3 serves as the connecting rope between the sliding steel formwork 11 and the hand-pulled hoist. There are a total of 14 stoppers 4. The stoppers 4 are used to control and adjust the positions of the wooden formworks on both sides of the slope concrete casting, facilitating the construction of jointing and block division according to the design drawings.

[0031] The limiting rod 5 is made of a steel pipe of A48 and passes through the stopper 4, closely adhering to the side formwork 14 to prevent the side formwork 14 from deforming or shifting, which may affect the quality of the concrete. For the random formwork position 6, the formworks in this area can be steel formworks or glued wood formworks, and the formwork thickness can be randomly selected according to the on-site situation, and then fixed by using the stoppers 4 and the limiting rods 5.

[0032] There are a total of 8 rollers 7, and the rollers 7 are fixed on the sliding steel formwork 11 to reduce the friction between the longitudinal middle support 9 and the longitudinal side support 12. The transverse hoops 8 are set to 3, dividing the casting support into 4 parts and connecting with the original system bolts on the slope to prevent outward expansion during the concrete casting, resulting in a change in the elevation of the panel.

[0033] The longitudinal middle support 9 has the same sliding direction as the sliding steel formwork 11, serving as the overall support of the casting support. The bottom cross beam 10 serves as the transverse support in contact with the ground at the bottom of the casting support. The sliding steel formwork 11 serves as the main formwork for the concrete casting, and is connected to the lifting system of the casting support to slide at a uniform speed.

[0034] The longitudinal side support 12 is connected to the stopper 4 and the limit rod 5, playing a role in overall support and fixing the side formwork 14; the steel formwork pressing piece 13 fixes the sliding steel formwork 11 and the pouring support as a whole, preventing the concrete poured from deforming due to gravity and the thickness of the poured concrete not meeting the design requirements; the side formwork 14 prevents the concrete poured from overflowing due to the action of gravity.

[0035] Installation process: Determine the installation position of the device → Install the lifting frame → Install the inner and outer girders → Tie the vertical steel bars and the horizontal steel bars under the lifting crossbeam → Install the formwork → Install the operation platform and the inner hanging bracket → Install the lifting system → Install the outer hanging bracket and the safety net (after sliding open 2 m). It is divided into three stages: initial lifting, normal sliding and final lifting. After entering the normal sliding, if it is necessary to suspend the sliding, stop-sliding measures need to be taken (the stop-sliding construction joint is made into a V shape).

[0036] 1. Determine the installation position of the device: Measure and set out according to the jointing and block division of the construction drawings, and determine the device position based on the size of the structural joint. 2. Install the lifting frame and the girders: Before pouring, install according to the pouring thickness and direction required, and fixedly connect with the anchor bolts of the original slope support. First install the longitudinal side and middle supports, then install the bottom crossbeam, and finally install the transverse girders and support and connect them fixedly with the systematic anchor bolts of the slope.

[0037] 3. Install the lifting system: After the overall support is installed and fixed, install the lifting system, and fixedly connect the cable and the chain block with the sliding formwork. 4. Install the outer hanging ring and the safety net: When sliding to more than 2 m, install the hanging ring and the safety net for the operators.

[0038] During the construction of the utility model, according to the concrete pouring state, pulling the sliding formwork upward by the chain block can form a new poured formwork structure. Using this device for construction greatly simplifies the installation procedures of the glued laminated wood formwork, tie rods and formwork at the construction site; this device is integral, greatly improving the operation space for construction workers, facilitating the adjustment of operations by construction workers and timely arrival; this device is easy to disassemble, easy to assemble, reusable, greatly improving the formwork utilization rate, facilitating handling while reducing potential safety hazards; this device is integral after assembly, with a stable connection structure, capable of reducing the difficulty of concrete pouring, improving the quality of the poured concrete, and meeting the on-site construction progress; compared with the prior art, using the utility model can reduce the mechanical and labor costs and avoid the waste of construction resources.

[0039] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model.
