Description

Technical Field

[0001] The present invention relates to the field of high formwork safety technology, and more particularly to a high formwork safety protection system and a safe construction method for inclined floor decks. Background Art

[0002] During the construction of top supports for inclined floor decks, a high-formwork support system is typically used. This support system must ensure the angular stability of the inclined floor deck, while also ensuring the structural stability and reliability of the support system. Existing high-formwork typically features separate adjustment components at both the bottom and top, with various structural forms.

[0003] For example, patent application publication number CN102561668A discloses a top-supported portal scaffolding, which features an adjustable base and an adjustable support seat, capable of adjusting the height of the top support. The bottom of the adjustable base and the top of the adjustable support seat are generally arranged perpendicular to the support system (i.e., ideally, horizontally). Due to the flatness of the structure at the bottom of the adjustable base, the bottom surface of the bottom adjustment component cannot be accurately maintained in a parallel horizontal plane. Furthermore, as the number of high-rise formwork layers increases, the support system columns, i.e., the enterprise management structure in CN102561668A, will deviate from the required verticality by a certain angle, making it difficult for the top surface of the adjustable support seat to be parallel to each other. Ultimately, point contact support is easily formed between the top of the adjustment component and the floor deck, resulting in low support stability for the floor deck, which can easily damage the bottom surface during concrete pouring. When the parallelism of the top surfaces of all adjustable support seats cannot be ensured, it will directly affect the lateral inclination angle and longitudinal horizontality of the top-supported floor decking. After the top support, it is necessary to re-measure the lateral inclination angle of the floor decking to see if it meets the requirements and whether the longitudinal horizontality is up to standard, which makes the entire implementation operation steps cumbersome. Regardless of whether any of the lateral inclination angle and longitudinal horizontality is not up to standard, it will easily cause concrete leakage at the side nodes of the inclined floor decking, and in serious cases, safety accidents may occur.

[0004] It can be seen that in practical construction, in the high-formwork support system of floor decking, especially inclined floor decking, the safety, stability and ease of operation of the support are important considerations. How to improve the performance of the support system on the basis of facilitating construction operations is of great significance. Summary of the Invention

[0005] 1. Technical problem to be solved by the invention

[0006] The purpose of the present invention is to provide a safety protection system and a safe construction method for high-support formwork of inclined floor decking.

[0014] Furthermore, the wedge block includes a connecting plate installed on the support plate, and an adjusting plate rotatably and cooperatively installed with one end of the connecting plate.

The top of the sliding body is rotationally and cooperatively connected with the support body. The adjusting member is used to drive the sliding body to perform horizontal sliding, so as to drive the opening and closing rotation of the free end of the adjusting plate.

[0016] Furthermore, the adjusting member adopts a screw rod. The adjusting member passes through the fixed seat and extends towards the inner side of the connecting plate. The sliding body is threadedly and cooperatively installed with the adjusting member, and a guiding member extending horizontally is arranged between the bottom of the sliding body and the inner wall of the connecting plate.

[0017] Furthermore, it also includes a top support assembly arranged between the skeleton support unit and the shear wall.

[0018] Furthermore, the top support assembly includes a support fixed on the shear wall, a top support sub-plate is provided on the outside of the support, and a plurality of groups of top support members are also provided on the outer surface of the top support sub-plate at evenly spaced intervals along the circumferential direction.

[0037] The present invention will be further described below with reference to the embodiments.

[0038] Embodiment

[0039] Combined with Figures 1 - 4 For the high - formwork safety protection system of the inclined floor - bearing plate in this embodiment, it includes a skeleton support unit 1 and a safety support unit 2. The skeleton support unit 1 is located below the floor - bearing plate, and the safety support unit 2 is arranged on the top of the skeleton support unit 1 and supports the floor - bearing plate. Specifically, the safety support unit 2 includes a fixing plate 21 fixedly installed on the top of the skeleton support unit 1. A plurality of groups of adjusting structures 22 are arranged at equal intervals along the circumferential direction on the fixing plate 21. The tops of the plurality of groups of adjusting structures 22 are commonly connected with a support plate 23. The plurality of groups of adjusting structures 22 are used to adjust the height of the support plate 23 and keep the support plate 23 in a horizontal state all the time. A wedge - shaped block 24 that fits and supports the bottom surface of the floor - bearing plate is arranged on the top of the support plate 23.

[0040] In this embodiment, three groups of adjusting structures 22 are provided and arranged in an equilateral triangle. The adjusting structure 22 includes an adjusting screw 221 rotatably installed on the fixing plate 21. A guide rod 222 is also installed on the upper surface of the fixing plate 21. Specifically, two groups of guide rods 222 are symmetrically installed on both sides. A baffle 223 is installed on the tops of the two groups of guide rods 222. The adjusting screw 221 is located between the two groups of guide rods 222, and the top of the adjusting screw 221 is rotationally and cooperatively connected with the baffle 223. A slider 224 that moves up and down relative to the guide rod 222 is in threaded cooperation with the outer circumference of the adjusting screw 221. The guide rods 222 respectively pass through both sides of the slider 224. A rotating shaft one 228 is rotationally and cooperatively installed on the slider 224, and a corresponding rotating shaft two 225 is rotationally and cooperatively installed on the lower surface of the support plate 23. Pins are respectively arranged at both ends of the rotating shaft one 228 and the rotating shaft two 225, and the pins at both ends of the rotating shaft one 228 and the rotating shaft two 225 are respectively connected by a connecting rod 227. More precisely, that is, the fixed installation positions of the three groups of rotating shafts two 225 on the lower surface of the support plate 23 are arranged in an equilateral triangle, and the fixed installation positions of the three groups of rotating shafts one 228 are arranged in an equilateral triangle. The adjusting structure 22 is suitable for adjusting the height of the support plate 23, and during the adjustment process, the support plate 23 is always in a horizontal state. This horizontal state means being parallel to the horizontal plane, that is, being horizontal both horizontally and longitudinally. The wedge - shaped block 24 is suitable for supporting the floor - bearing plate.

[0041] In this embodiment, a horizontally arranged support plate 23 is redesigned on the top of the safety support unit 2 as a reference platform. The adjusting screw 221 of the adjusting structure 22 drives the slider 224 to move up and down along the guide rod 222, which will cause the first rotating shaft 228 on it to rotate at a certain angle. Then, through the connecting rod 227, the height and horizontal relative position of the support plate 23 are adjusted. Whether adjusting one or two adjusting screws 221 simultaneously or separately, only the relative height of the support plate 23 and its relative position relative to the fixed plate 21 can be adjusted, and the horizontal state of the support plate 23 cannot be changed. The wedge block 24 is used to safely support the inclined floor slab.

[0042] In practice, as different embodiments of the wedge block 24, optionally, a limiting groove is provided at the top of the support plate 23, and the wedge block 24 is fixedly installed in the limiting groove, and an anti-slip pattern is provided on the upper surface of the wedge block 24. The upper surface of the wedge block 24 is used to directly contact and support the inclined floor slab, and adding the anti-slip pattern can effectively improve the support stability. The inclination angle of the upper surface of the wedge block 24 corresponds to the inclination angle of the inclined floor slab to achieve mutual fitting support of the inclined surfaces.

[0043] As another implementation of the wedge block 24, as shown in Figure 3 The wedge block 24 includes a connecting plate 241 fixedly installed on the support plate 23, and an adjusting plate 242 rotatably installed at one end of the connecting plate 241. A support body 243 is rotatably installed at the bottom of the free end of the adjusting plate 242; a fixed seat 244 is provided at the end of the connecting plate 241, an adjusting member 245 is arranged on the fixed seat 244, and a sliding body 246 is installed in cooperation with the adjusting member 245. The top of the sliding body 246 is rotatably matched with the support body 243, and the adjusting member 245 is used to drive the sliding body 246 to slide horizontally, so as to drive the opening and closing rotation of the free end of the adjusting plate 242. Specifically, the adjusting member 245 is a screw, the adjusting member 245 passes through the fixed seat 244 and extends towards the inner side of the connecting plate 241, the sliding body 246 is installed in threaded cooperation with the adjusting member 245, and a horizontally extending guiding member is provided between the bottom of the sliding body 246 and the inner wall of the connecting plate 241. For example, the cooperation form of a guiding block and a guiding groove can be adopted between the wall surfaces where the sliding body 246 contacts the connecting plate 241 to realize the adjustment of the horizontal axial displacement of the sliding body 246 by the screw. The top of the sliding body 246 is connected to the bottom of the support body 243 through a rotating shaft, and the top of the support body 243 is connected to the bottom of the free end of the adjusting plate 242 through a rotating shaft. In this way, when the sliding body 246 moves horizontally axially, the inclination angle change of the adjusting plate 242 can be controlled, so that it can be adapted to the fitting support of floor slabs with different inclination angles according to the use requirements.

[0044] In practical applications, another optional implementation is that the top of the wedge block 24 can be set as a multi-level stepped surface that is consistent with the inclined direction of the floor formwork. That is, the tangent connection of the top contour lines of each level of steps still maintains the same inclination angle as the floor formwork. In this way, the effect of multi-level linear support is achieved at the top of the multi-level steps, and a relatively stable support effect can also be realized. Moreover, when facing a relatively special stepped floor formwork, a step design adapted to the floor formwork can be correspondingly adopted to achieve a fitting support with the steps.

[0045] To further improve the overall support stability effect, a more optimized solution is that in addition to the above-mentioned safety support unit 2, the safety protection system of this embodiment further includes a top support assembly 3 arranged between the skeleton support unit 1 and the shear wall. The top support assemblies 3 are spaced apart along the height extension direction of the skeleton support unit 1 and provide a horizontal support force to the skeleton support unit 1. In practice, at least one set of top support assemblies 3 is arranged at the top and bottom positions on both sides of the skeleton support unit 1.

[0046] Specifically, as shown in Figure 4 The top support assembly 3 includes a support 31 anchored and installed on the shear wall. The support 31 has anchoring installation positions at the upper and lower ends, and a component installation position frame extending outward in the middle. X-shaped reinforcing rib plates are provided between the four corners inside the component installation position frame, and horizontal reinforcing rods are respectively connected to the upper and lower parts of the X-shaped reinforcing rib plates to improve the strength and stability of the overall frame structure. A horizontal axial top support structure is installed outside the support 31. The horizontal bearing top support structure includes a top support sub-plate 32 installed outside the support 31. On the outer surface of the top support sub-plate 32, multiple groups of top support members 33 are also evenly spaced along the circumferential direction. Specifically, there are three groups. The outer ends of the three groups of top support members 33 are commonly connected to a top support main plate 34. The structure of the top support member 33 is the same as that of the adjustment structure 22 and will not be elaborated here; the top support member 33 is used to adjust the position of the top support main plate 34 and keep the top support main plate 34 always in a vertical state; a top support body 35 for cooperating and clamping with the skeleton support unit 1 is also provided on the top support main plate 34. The top support body 35 can specifically adopt an arc-shaped top support body 35 adapted to the clamping position of the skeleton support unit 1. By adjusting the top support member 33, the control of the all-round movement of the top support main plate 34 in the up-down, left-right, front-back directions can be realized, so that the top support body 35 can adapt to the positions of the vertical rods and horizontal rods in the skeleton support unit 1, realize the horizontal axial top support function, and ensure the structural stability and reliability of the skeleton support unit 1.

[0047] The safety construction method of the above-mentioned inclined floor formwork high support formwork safety protection system of this embodiment is as follows:

[0048] During assembly: erect the skeleton support unit 1 layer by layer, install multiple sets of safety support units 2 at intervals along the length direction on top of the skeleton support unit 1, and use the calibration ruler to adjust so that the support surfaces of the wedge blocks 24 of the multiple sets of safety support units 2 are on the same inclined plane, then install multiple sets of top support assemblies 3 at intervals along the height direction of the skeleton support unit 1, and finally hoist the floor deck and pour concrete;

[0049] Specifically, the fixing plate 21 is installed on the top of the skeleton support unit 1, and the pins on the assembly shaft 1 228 and the shaft 2 225 are connected by the connecting rod 227. The wedge block 24 is installed on the top of the support plate 23. By adjusting the corresponding adjustment screw 221 on the corresponding fixing plate 21 and using the calibration ruler, it is ensured that the upper surfaces of the two adjacent wedge blocks 24 are in the same inclined plane. Then, the top support components 3 near the top and bottom of the skeleton support unit 1 are installed. The top support components 3 are used to enhance the stability and anti-overturning property of the skeleton support unit 1. Finally, the floor deck is hoisted and concrete is poured.

[0050] During dismantling, after the cast-in-place concrete is cured, the safety support unit 2 is adjusted to separate the wedge block 24 from the bottom surface of the floor deck, and the skeleton support unit 1 and the top support assembly 3 are removed in sequence from high to low.

[0051] In this embodiment, a reference plate parallel to the horizontal plane is re-established in the safety protection system. The floor decking can be quickly supported by the wedge blocks 24 on the reference plate. Since the supporting surfaces of all the wedge blocks 24 are coplanar, the longitudinal horizontality of the floor decking can be ensured. The lateral inclination angle of the floor decking can be ensured by adjusting the elevation of the reference plate. The operation steps are simple and quick, and there is basically no need to re-measure the lateral and longitudinal indicators of the floor decking. It can effectively reduce labor intensity, improve work efficiency, and relatively improve construction safety.

[0052] The above is a schematic description of the present invention and its embodiments. This description is not restrictive and is only one embodiment of the present invention. Therefore, if a person skilled in the art is inspired by this description and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without creatively designing them, they shall fall within the scope of protection of the present invention.
