Description

Technical Field

[0001] The present invention belongs to the field of infrastructure engineering, and in particular relates to a multi-faceted embedded part installation and concrete pouring construction device and a construction method. Background Art

[0002] In the water retaining structures of water conservancy projects, the concrete pouring and metal structure installation of the gate slots are particularly important. The installation accuracy of the main and reverse rails of the gate slots directly affects whether the water retaining components behind them can fall smoothly and whether the water-stopping seals in each part can effectively ensure the water-stopping effect and meet the actual needs of the project. In many gate slot constructions, there are main reverse rails and side rails, and the processing and precision requirements of each rail surface are relatively high. A supporting slide with a thicker protruding surface is designed on the main rail to contact the gate slider, play a guiding role and reduce friction. Therefore, the installation position and verticality requirements of the slide at this position are particularly high; there is also a thinner water-stop stainless steel surface on the main rail, which requires mechanical processing, and secondary operations or welding and installation of various auxiliary tooling are prohibited on the surface.

[0003] The counter-rail is designed with a protruding surface with a thicker part as a reverse support. The side rail is designed to be separated from the main counter-rail, and the three do not form a whole. Therefore, during the pouring process, the side still needs a template to cooperate with the pouring of concrete. According to the above, it is particularly important to grasp the installation accuracy during the track installation process, so the concrete pouring construction device must be non-destructive to the track. Existing construction platform devices all weld corresponding auxiliary tooling on the cast door groove to ensure the platform stability and load-bearing force. This method not only affects the surface structure of the embedded parts of the door groove, but also requires a long time of high-altitude operation to clean, grind, polish and re-anticorrosion of the original welding tooling surface after the overall construction is completed. The construction requirements are high and the process is complicated.

[0004] For this type of track arrangement, the main civil engineering concrete structure can use either flip formwork or climbing formwork. However, when pouring the side rails, the side rails cannot be connected to the main concrete formwork after the main counter-rails on both sides are installed. Therefore, the simplest pour-and-support method can only be used. The outside of the formwork must also be fixed with the installed (unpoured) metal structure, which means that the installed metal structure will bear the lateral pressure of all concrete on the opposite side formwork, causing the installed structure to shift. The re-measurement results after the entire concrete is compared with the initial installation, and there is a large error. The lateral support of the side formwork is provided by the door groove. The current supporting devices and positioning devices all use the door groove as the main force point, and it is difficult to cooperate with the flip formwork and sliding formwork during the synchronous pouring process, which reduces construction efficiency and makes it difficult to ensure installation accuracy. Summary of the Invention

DETAILED DESCRIPTION

[0039] The existing concrete pouring process for piers and door slots requires the installation of embedded parts, which means that the pouring process can only be divided into one and two phases. In some cases, the one-time pouring of the first phase requires the use of many auxiliary lifting equipment and machinery, which not only leads to a sharp increase in costs, but also makes it difficult to achieve the installation accuracy required by the design. To address this series of problems, the present invention provides a concrete pouring construction device and construction method. The specific solution is as follows:

[0040] The preferred solution is Figures 1 to 12 As shown, a multi-faceted embedded parts installation and concrete pouring construction device includes a structural frame 1, and a plurality of climbing devices 6 are provided on the structural frame 1. The climbing devices 6 are used to move along the platform rising climbing rod 5, and the platform rising climbing rod 5 is used to be embedded in the concrete; the structural frame 1 is connected to the formwork 4 through the formwork connecting rod 8; the edge of the structural frame 1 is provided with a plurality of adjustable lateral support devices, and the plurality of adjustable lateral support devices are symmetrically distributed on both sides of the structural frame 1.

[0041] The structural frame 1 is used to be installed in the door slot. The structural frame 1 is mainly used for bearing weight and force. It is welded from profiles and can be made into a steel frame that meets the construction requirements according to different working conditions. The structural frame 1 can be lifted in the vertical direction along the platform rising climbing rod 5. When the structural frame 1 is lifted, the adjustable lateral support device is in a retracted state, so that there is no friction between the adjustable lateral support device and the door slot. The platform rising climbing rod 5 is fixed in the concrete of the first bin that has been poured. Part of the platform rising climbing rod 5 is exposed in the area to be poured. The platform rising climbing rod 5 is installed vertically so that the structural frame 1 can rise smoothly. The climbing device 6 is installed on the bracket of the structural frame 1 through the connecting bolts 7. The bracket is fixed to the structural frame 1.

[0042] Furthermore, the adjustable lateral support device includes a fixed screw sleeve 13 connected to the structural frame 1, the fixed screw sleeve 13 is threadedly engaged with the adjustable screw 3, and the adjustable screw 3 is connected to the lateral support slider 2. An adjusting nut 12 is coaxially provided on the adjustable screw 3.

[0043] Several groups of lateral support sliders are arranged at the contact positions of the door groove tracks on both sides of the light steel structure frame. The fixed screw sleeve is reliably fixed to the light steel structure frame and is on the same center line as the transverse beam of the light steel structure frame. The adjustable screw is installed together with the fixed screw sleeve. The other side of the adjustable screw is connected to the lateral support slider. The slider can provide sufficient friction and hydraulic climbing device to maintain the stability of the entire structure and ensure the bearing capacity. The number of lateral support sliders on both sides is arranged according to actual needs. After the entire structure is installed and leveled, the length of the adjustable screw is controlled by adjusting the nut. When the entire structure needs to be lifted, the adjustable screw is retracted into the fixed screw sleeve. At this time, there is no friction resistance between the door groove surface and the entire structure, and the steel structure can be lifted.

[0044] Furthermore, the climbing device 6 is a hydraulic climbing device that utilizes a hollow hydraulic jack, which is used to move along the platform climbing rod 5. The hollow hydraulic jack ascends the platform climbing rod 5 through the oil injection and return actions of the hydraulic station. The hollow hydraulic jack can solve the problem of mismatching the concrete setting speed with the main body during pouring, allowing it to climb in unison with the main body during lateral concrete pouring.

[0045] Furthermore, the number of climbing devices 6 is at least four, and the multiple climbing devices 6 are evenly distributed on the edge of the structural frame 1.

[0046] The whole climbing is relied on the hydraulic climbing device to ascend along the platform to make vertical upward lifting. The power source of the hydraulic climbing device is a special hollow hydraulic jack. The hollow hydraulic jacks should be arranged to make the jacks balanced. The hollow hydraulic jacks are arranged uniformly or in groups at equal intervals. The platform ascending climbing pole should meet the corresponding specifications and the actual construction environment on site in the aspects of the embedded depth in the concrete and the maximum distance of emptying.

[0047] The construction precision control mainly includes the limiting leveling device of the lifting equipment itself, the observation and adjustment control facilities of the horizontal degree and the vertical degree of the device in construction, etc. The jack synchronous control device can adopt limiting clamping, laser level scanner, water cup automatic control device, etc. The verticality observation equipment can adopt laser plumb instrument, automatic leveling laser plumb instrument, theodolite and plummet, etc. The precision thereof should not be lower than 1 / 10000. How many jacks are supplied by each hydraulic console can be calculated according to the oil consumption of each jack, the gear pump oil capacity and time. If the oil tank capacity is insufficient, a vice oil tank can be added. For the project with large working surface and more installed jacks and using the same operation platform, two or more sets of hydraulic consoles can be installed together.

[0048] After the hydraulic system is installed, the trial operation should be carried out. First, the oil charging and exhaust are carried out, and then the pressure is increased to 12N / mm. Each time the pressure is maintained for 5min, and the process is repeated for 3 times. After the overall inspection is carried out and no leakage is found at each sealing position, the platform ascending climbing pole is inserted.

[0049] The platform ascending climbing pole is the track of the jack movement, and supports the whole load acting on the jack. In order to make the supporting pole not produce compression buckling deformation, the round steel or steel pipe with certain strength should be used. The upper and lower centers should be coincided on a vertical line, so as to make the hollow hydraulic jack climb smoothly.

[0050] Further, the structural framework 1 is a light steel structural framework, the framework structure is Q355C, the sliding block is MGB, and the others are Q235B.

[0051] Further, the formwork 4 is in sliding fit with the side rail 14. The formwork is reliably fixed and connected with the light steel structural framework. After the light steel structural framework is installed and adjusted, the side formwork is adjusted to the appropriate position according to the drawing requirements to meet the concrete pouring requirements. The formwork device is lifted together with the structure during the whole structure lifting process.

[0052] Specifically, the side of the template 4 is provided with a concave groove that cooperates with the side rail 14, and a plurality of positive sliders 9 are provided in the concave groove. A reverse slider 11 is provided on the side opposite to the positive slider 9. The reverse slider 11 is connected to the template 4 through the reverse slider bracket 1, and the reverse slider 11 cooperates with the positive slider 9 to clamp the side rail 14. The template 4 includes a steel template, which is made of profile plate and has reinforcing ribs. The steel template is connected to the structural frame 1 through the template connecting rod 8. A concave groove is provided on the steel template, and the length and width of the concave groove are consistent with the size of the side rail 14. The concave groove is provided with a plurality of positive sliders or rollers. The design purpose of the reverse slider 11 and the positive slider 9 is to reduce friction and provide good support when the entire device slides, while ensuring the overall installation accuracy.
