Description

Technical Field

[0001] The present invention relates to the technical field of building construction, in particular to a disc-type formwork frame erection structure and a construction method thereof. Background Art

[0002] With the rapid development of the construction industry, the requirements for workers' construction efficiency and safety are increasing. Traditional support systems can no longer meet the needs of modern construction in some aspects. Among them, the disc-type formwork frame has been widely used in the field of construction due to its outstanding advantages of high construction efficiency and strong bearing capacity. For example, in the construction of nuclear power projects, the erection of formwork frames is particularly important.

[0003] During the construction process using a disc-type formwork frame, the formwork frame supports the formwork by lifting it to the same horizontal height (this method can be called slab construction operation). However, in the actual construction process, the formwork frame not only needs to support the slab construction formwork, but also needs to support the beam formwork that is not at the same height as the slab construction (the operation of supporting the beam formwork is called beam construction). The load-bearing beam formwork is an inverted "J"-shaped structure, and the horizontal height of its lower end is lower than the height of the slab construction formwork. In order to realize the beam construction operation, it is often necessary to rebuild a new supporting structure. If necessary, it is also necessary to dismantle and reorganize the supporting structure that has been built for slab construction, which leads to low construction efficiency and great disadvantages.

[0015] In order to solve the above technical problems, the present invention also provides a construction method for erecting a disc-type formwork frame structure, comprising the following steps:

[0016] S1. Measurement and layout: Before installation, lay out the lines on the bottom plate and floor slab according to the layout drawing, set up the frame according to the designed position, and check whether the layout points are correct. When laying out the lines, the arrangement should be based on the type of components supporting the concrete structure. The drop-down area, large-section beams, and hanging components should be clearly marked on the foundation ground to facilitate the frame support in one step and avoid additional reinforcement;

[0017] S2. Bottom support structure construction: Material preparation personnel distribute materials according to the required number of scaffolding and deliver them to each scaffolding area. Adjustable bases are set up according to the positions of each fulcrum and fixed with horizontal rods. The height of the horizontal rods from the ground should not exceed 550mm. The adjusted positions are correctly placed according to the construction drawings of the formwork support frame.

[0018] S3. Install bottom poles: Install the poles required for bottom support. The length range is 3m / 2m / 1.5m, which is selected according to the overall installation height. The middle joints of the poles should be staggered.

[0019] S4. Horizontal rod installation: After the vertical rods are installed, install diagonal rods on the vertical rods at a step distance of 1.5m. Multiple groups of diagonal rods are installed horizontally in sequence to form a rectangular structure.

[0020] S5. Install the bottom diagonal rods: Assemble the diagonal rods in a clockwise or counterclockwise direction. First, insert the diagonal rods into the large-sized limiting holes on the connecting plate, so that the front end of the diagonal rods rests against the vertical rod tube. Then, use the pin plate to penetrate the large-sized limiting holes and tighten to secure. The diagonal rods are directional and cannot be overlapped if they are in the opposite direction.

[0021] S6. Installation of upper support structure: After the bottom layer of diagonal rods are installed, the adjacent bottom support structure disc-shaped truss units are connected into a whole with horizontal rods, and then the above steps are repeated to build the upper support structure to the designed height;

[0022] S7. Install the top adjustable support 1: Install the adjustable support 1 on the top of the vertical pole of the upper support structure. Place the steel main keel supporting the formwork on the adjustable support 1. Build multiple groups of wooden secondary keels on the steel main keel to assist in the slab construction support operation.

[0023] S8. Install the shelving beam support system: First install the beam. Utilize the cross-sectional characteristics of the steel frame and fix the steel frame between two sets of vertically parallel vertical poles using a fixing fixture. Install the adjustable support bracket 2. Insert the lifting screw with a diameter of Ф38 vertically into the support bracket. The length of the lifting screw extending from the top shall not exceed 400mm. During installation, ensure that the upper and lower parts are concentric and the bracket notches are oriented in the same direction. Place the steel main keel on the lifting screw. Build multiple sets of wooden secondary keels on the steel main keel in sequence to support the beam formwork. Adjust the overall lifting height of the adjustable support bracket 2 so that the steel main keel, wooden secondary keel, and formwork can be adjusted in height together to achieve precise adjustment of the formwork elevation.

[0024] S9. Formwork installation: Determine the size of the formwork arch based on the beam span: no arching is considered for beams <4m; 4m ≥ L> 12m, the arching is 2‰ of the span; L ≥ 12m, the arching is 3‰ of the span; cantilever components are arched at 4‰ of the span;

[0025] S10. Precautions for erection: All components should be installed according to the design and relevant regulations of the buckle frame; the on-site foundation should be cleaned before construction; the frame elevation and position should be adjusted by adjusting the vertical poles and horizontal poles according to the actual situation on site to ensure that the support requirements of the frame are met; during the erection process, attention should be paid to adjusting the verticality of the frame, requiring the verticality of the entire frame to be less than 1 / 500L, and the maximum allowable deviation is 50mm; when erecting or changing the operating procedures, unrelated personnel are prohibited from entering the dangerous area; according to the needs of on-site construction, a pedestrian passage is set up around the structure, and the outside of the passage is covered with a dense mesh net and reliably connected to the frame; a horizontal scissors brace is set every 4-6 steps of the frame, and the width of the scissors brace is 4-6m, and the safety flat net is arranged according to the number of scissors brace layers.

[0026] Beneficial effects of the present invention:

[0027] 1. A shelving crossbeam support system is provided to support the beam construction, and the shelving crossbeam support system is directly built on the upper half of the plate support system. It can be directly combined with the plate support system required for the plate construction operation to form an integral whole. The two jointly use the lower part of the plate support system for load support. Compared with the existing technology, there is no need to build an additional bottom support structure for beam construction, thereby saving construction materials and shortening the construction and installation period.

[0028] 2. The buckle adopts a standardized construction process and an efficient connection method. Compared with the existing construction technology, it can save 15% of the formwork support materials and 10% of the labor costs. By connecting the buckle with the angle steel material, a firm connection between the shelving beam support system and the support frame uprights is achieved, thereby improving the stability of the overall structure.

[0029] 3. The beam support system and the plate support system are connected by two sets of symmetrically arranged fixing clamps. Each set of fixing clamps can apply inward clamping and fixing forces from the front and back sides through two sets of clamping parts set on the front and back sides. The two sets of symmetrically arranged fixing clamps can apply inward clamping and fixing forces from the left and right sides through two sets of abutment parts in a symmetrical position relationship, and the buckles apply upward supporting force to the steel frame from bottom to top. Therefore, by applying limiting fixing and clamping forces in multiple directions and positions, the intimacy and stability of the connection between the two can be effectively guaranteed, thereby improving the installation stability of the overall structure.

[0045] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0046] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0047] Example 1

[0048] Reference Figures 1 to 12 , which is the first embodiment of the present invention, comprises a disc-type formwork erection structure, including a plate support system and a shelf beam support system, the shelf beam support system comprising two sets of symmetrically arranged steel frames 6, two sets of adjustable supports 7 vertically inserted into the two sets of steel frames 6, and two sets of fixing clamps 8 symmetrically arranged at both ends of the steel frames 6;

[0049] The fixing fixture 8 includes a fixing part 81 abutted against one end of the steel frame 6, and a slide groove 812 is provided on both sides of the fixing part 81, which is inserted into the driving part 82 at the axial position of the fixing part 81, a driven part 83 rotatably connected to the driving part 82, and a spiral rack 833 of a spiral structure is provided on the inner side of the driven part 83, a clamping part 84 with an L-shaped structure inserted into the slide groove 812, and a plurality of groups of teeth 844 are spirally distributed on one side of the clamping part 84, and the teeth 844 are meshed with the spiral rack 833 for transmission, an abutting part 85 is transversely threadedly connected to the axial position of the fixing part 81, and one end of the abutting part 85 extends into the driving part 82, and a connecting part 86 is provided on one end of the abutting part 85 located in the driving part 82.

[0050] Among them, reference Figure 5 The fixing component 81 includes a fixing seat 811, and the sliding groove 812 is vertically offset and parallel to the fixing seat 811, a limit block 813 is arranged inside the end of the sliding groove 812, a sleeve 814 fixedly connected to one side of the axial position of the fixing seat 811, and a connecting shaft 815 is arranged at the outer end of the sleeve 814, and the abutment component 85 is threadedly connected to the connecting shaft 815, the fixing seat 811 is used to install the fixing component 81, the clamping component 84 and the abutment component 85, the sliding groove 812 cooperates with the limit block 813, so that the clamping component 84 can only slide along the sliding groove 812 and cannot be separated from the fixing component 81.

[0051] Among them, reference Figure 4The driving component 82 includes a driving shaft 821 inserted into the axis position of the fixing seat 811, a limiting ring 822 fixedly set on the driving shaft 821, a clearance groove 823 opened in the driving shaft 821, a gear ring 824 sleeved on the driving shaft 821, a bolt 826 set at the outer end of the driving shaft 821, and a spring 825 sleeved on the driving shaft 821 and located between the gear ring 824 and the bolt 826. The driving component 82 is limited on the fixing component 81 by the limiting ring 822 and can be fixed. The axis position of component 81 performs axial rotation without changing its position. Gear ring 1 824 is elastically supported by spring 1 825 and is always engaged with gear ring 2 832. At this time, the rotation of driving component 82 can drive gear ring 1 824 to rotate synchronously. Bolt 826 is a common hexagonal bolt structure. The wrench can drive the driving component 82 to rotate through bolt 826. The wheel set at the end of the driving shaft 821 can also drive the driving component 82 to rotate. The makeshift groove 823 is used to accommodate the installation connection component 86.

[0052] Furthermore, the section of the drive shaft 821 on which the gear ring 1 824 is sleeved is rectangular, and the section of the drive shaft 821 that penetrates into the driven component 83 is a cylindrical structure. A rectangular notch matching the rectangular section is provided in the gear ring 1 824, so that the gear ring 1 824 can not only rotate in a circle following the drive shaft 821, but also slide horizontally along the rectangular section of the drive shaft 821.

[0053] Among them, reference Figure 6 and Figure 10 The driven component 83 includes a turntable 831 sleeved on the driving shaft 821, and the volute rack 833 is fixedly connected to the inner side of the turntable 831, and the gear ring 2 832 is fixedly connected to the outer side of the turntable 831, and the gear ring 2 832 is engaged with the gear ring 1 824. The spiral structure of the volute rack 833 makes it a smooth spiral transition between its end and the innermost end. An object moving along its spiral direction will gradually move away from or approach the center of the volute rack 833. The movement of moving away or approaching is driven according to the overall rotation direction of the volute rack 833. The gear ring 2 832 is engaged with the gear ring 1 824, so that when the driving component 82 rotates, it can synchronously drive the driven component 83 to rotate as a whole.

[0054] Among them, reference Figure 4 and Figure 10The clamping component 84 includes a slide bar 841 inserted into the slide groove 812, and the teeth 844 are fixedly connected to the outer side of the slide bar 841, a slot 842 is provided on the slide bar 841, and the limit block 813 is inserted into the slot 842, and a splint 843 is transversely arranged at the outer end of the slot 842. The two groups of clamping components 84 are respectively close to the outer sides of the two groups of steel frames 6, and the splints 843 at both ends of the clamping component 84 are parallel to the steel frame 6. The slot 842 cooperates with the limit block 813 to ensure that the slide bar 841 moves normally along the slide groove 812 while not separating from the fixed component 81. The teeth 844 are inclined The inclined posture is set, and the inclination angle is tangent to the spiral path of the spiral rack 833. Therefore, when the spiral rack 833 rotates, the teeth 844 will be cut into its spiral path. Since the slide bar 841 is limited by the slide groove 812, the spiral rack 833 will push the teeth 844 to move when it rotates. The moving teeth 844 will synchronously drive the clamping part 84 as a whole to extend outward or retract inward. The two groups of clamping parts 84 are arranged relative to each other, so the two groups of clamping parts 84 will move in a synchronous manner but in opposite directions, thereby clamping the steel frame 6 from both sides and applying limiting forces from the front and rear sides.

[0055] Among them, reference Figure 4 The abutment component 85 includes an extension screw 851 threadedly connected to the connecting shaft 815, and one end of the extension screw 851 extends into the give way groove 823, a limiting groove 852 is opened on the extension screw 851, and a top plate 853 is arranged at the other end of the extension screw 851. The extension screw 851 is threadedly connected to the connecting shaft 815 and can continue to extend and retract at the axial position of the fixed component 81. The limiting groove 852 can ensure that the extension screw 851 does not disengage from the circumferential limit between the insertion block 862 when moving in the horizontal direction.

[0056] Among them, reference Figure 4 、 Figure 8 and Figure 9The connecting component 86 is arranged on the portion of the extension screw 851 located in the clearance groove 823. The connecting component 86 includes a gear ring 3 861 sleeved on the extension screw 851, an insert block 862 vertically arranged at the axial position of the gear ring 3 861, and the insert block 862 is slidably inserted in the limiting groove 852, sleeved on the gear ring 4 863 on the extension screw 851, and the gear ring 4 863 is engaged with the gear ring 3 861, sleeved on the limiting ring 2 865 on the extension screw 851, and the limiting ring 2 865 is engaged with the clearance groove 823. The inner wall is fixedly connected, and the spring second 864 is sleeved on the extension screw 851 and located between the gear ring four 863 and the limiting ring second 865. The gear ring three 861 is connected to the extension screw 851 in the circumferential direction through the insert block 862, and the two can perform synchronous rotation. The spring second 864 lifts the gear ring four 863 through elastic support, so that the gear ring four 863 and the insert block 862 are clamped together. Extension blocks 8631 (such as Figure 9 As shown in the figure, the driving shaft 821 is also provided with a sliding groove 8211 that matches it. The extension block 8631 cooperates with the sliding groove 8211, which can limit the gear ring four 863 and the driving shaft 821 in the circumferential direction, so that the two can rotate synchronously, and the gear ring four 863 can slide horizontally in the driving shaft 821 through the extension block 8631. The gear ring four 863 driven by the driving shaft 821 can synchronously drive the gear ring three 861 and the extension screw 851 to rotate, so that the extension screw 851 can be extended and retracted through the threaded drive of the connecting shaft 815.

[0057] Among them, reference Figure 11 The adjustable support 7 includes a support 71 inserted into the two groups of steel frames 6, a rectangular plate 72 arranged horizontally on the support 71, a lifting screw 73 inserted into the top of the support 71, a bracket 74 arranged at the top of the lifting screw 73, and an adjusting wrench 75 sleeved on the top of the support 71, and the lifting screw 73 passes through the adjusting wrench 75, and the two are in a threaded connection relationship. The lifting screw 73 is threadedly connected to the adjusting wrench 75, and the adjusting wrench 75 is limited and rotated at the top of the support 71. A rectangular block is provided at the end of the lifting screw 73, and a rectangular groove matching it is opened inside the support 71. Therefore, the lifting screw 73 is limited in the circumferential direction of the support 71 and can be displaced vertically along the support 71.

[0058] Among them, reference Figure 1The plate support system includes multiple groups of adjustable bases 1 distributed in parallel in the vertical direction, horizontal rods 2 built horizontally between every two groups of adjustable bases 1, vertical rods 3 connected to the top of each group of adjustable bases 1 in the vertical direction, diagonal rods 4 built obliquely between the vertical rods 3, and adjustable support 1 5 arranged at the top of the vertical rods 3. The adjustable base 1, horizontal rods 2, vertical rods 3, diagonal rods 4 and adjustable support 1 5 are all provided with vertical rods 3, and the five are all connected by connecting plates 31. The connecting plates 31 are provided with limiting holes of different sizes. The structure of adjustable support 1 5 is the same as that of adjustable support 2 7, so they can operate in the same way.

[0059] Further, refer to Figure 8 and Figure 9 The gear ring 1 824 and the gear ring 2 832 are matched with each other through the teeth of the triangular structure. When the torque between the two is large, the beveled edges of the teeth will guide the two sets of meshing teeth outward, causing them to move horizontally, thereby causing dislocation, so that the gear ring 1 824 and the gear ring 2 832 are no longer engaged for transmission, and the same is true for the gear ring 4 863 and the gear ring 3 861.

[0060] In summary, combined Figure 1 and Figure 12 When building the disc-type formwork support structure, the two groups of steel frames 6 are fixed between the two groups of vertical rods 3 that are parallel to each other in the vertical direction, and the two groups of steel frames 6 are respectively located on both sides of the vertical rods 3. At the same time, the bottom of the two groups of steel frames 6 are supported by the connecting disk 31, and the driving component 82 drives the gear ring 1 824 to rotate. The rotating gear ring 1 824 engages with the gear ring 2 832 to drive the driven component 83 to rotate. The rotating driven component 83 drives the teeth 844 through the spiral rack 833, so that the teeth 844 drive the clamping component 84 to slide horizontally along the slide groove 812, so that the clamping component 84 abuts against the steel frame 6 from the side, and the two groups of clamping components 84 move synchronously in opposite directions, and can clamp the two groups of steel frames 6 from the front and back sides (such as Figure 8 As shown in FIG5 ), limiting forces are applied from both the front and rear sides. After the clamping member 84 is clamped in place, the immovable clamping member 84 reversely limits the volute rack 833, so that the driven member 83 cannot move as a whole, while the driving member 82 continues to rotate. At this time, the torque between the first gear ring 824 and the second gear ring 832 increases, and the second gear ring 832 slides backward along the drive shaft 821. At this time, the two are misaligned, and the driving member 82 no longer drives the driven member 83 to rotate.

[0061] As the driving component 82 rotates, the gear ring four 863 rotates synchronously with the driving component 82. The rotating gear ring four 863 drives the extension screw 851 to rotate through the gear ring three 861. The rotating extension screw 851 will extend from the connecting shaft 815 and eventually lift the top plate 853 to abut against the side of the vertical pole 3. With the cooperation of the clamping limit of the clamping component 84, the abutting component 85 can apply a clamping force from the side. There are two sets of fixing clamps 8 installed at both ends of the steel frame 6. Therefore, there will be two sets of abutting components 85 to apply a clamping limit force from the left and right sides (such as Figure 7 As shown); whether the clamping member 84 is clamped in place first or the abutting member 85 is abutted in place first, the two will stop in time after either one completes the designated work, without hindering the other from continuing to work steadily, thereby improving the flexibility of the device;

[0062] In summary, combined Figure 7 It can be seen that by limiting the support from the front and back sides, left and right sides, and bottom, the limiting fixed clamping force can be applied in multiple directions and directions, effectively ensuring the closeness and stability of the connection between the two plate support systems and the shelving beam support systems, thereby improving the installation stability of the overall structure.

[0063] Furthermore, after the shelving beam support system is built on the upper half of the plate support system through the fixing fixture 8, the shelving beam support system can support the beam construction, and the shelving beam support system is directly combined with the plate support system required for the plate construction operation to form a whole. The two use the lower part of the plate support system to support the load. The load transfer between the two is as follows: Figure 13 As shown, compared with the prior art, the shelving beam support system is directly combined with the plate support system, so that there is no need to build an additional bottom support structure of the beam support system, thereby saving construction materials and shortening the construction and installation period.

[0066] S1. Measurement and layout: Before installation, lay out the lines on the bottom plate and floor slab according to the layout drawing, set up the frame according to the designed position, and check whether the layout points are correct. When laying out the lines, the arrangement should be based on the type of components supporting the concrete structure. The drop-down area, large-section beams, and hanging components should be clearly marked on the foundation ground to facilitate the frame support in one step and avoid additional reinforcement;

[0067] S2. Bottom support structure construction: Material preparation personnel distribute materials according to the required number of scaffolding and deliver them to each scaffolding area. Adjustable base 1 is set up according to the position of each fulcrum, and horizontal rod 2 is pulled up to fix it. The height of horizontal rod 2 from the ground should not exceed 550mm. The adjusted position is correctly placed according to the construction drawing of the formwork support frame.

[0068] S3. Install bottom poles 3: Install the poles 3 required for bottom support. The length range is 3m / 2m / 1.5m according to the overall installation height, and the middle joints of the poles 3 are staggered.

[0069] S4. Horizontal rod installation: After the vertical rod 3 is installed, install the diagonal rod 4 on the vertical rod 3 at a step distance of 1.5m. Multiple groups of diagonal rods 4 are installed horizontally in sequence to form a rectangular structure.

[0070] S5. Install the bottom diagonal rod 4: Assemble the diagonal rod 4 in a clockwise or counterclockwise direction. First, insert the diagonal rod 4 into the large-sized limiting hole on the connecting plate 31, so that the front end of the diagonal rod 4 is against the round tube of the vertical rod 3, and then use the pin plate to penetrate the large-sized limiting hole to tighten and fix it. The diagonal rod 4 has a directionality and cannot be overlapped if it is in the opposite direction.

[0071] S6. Installation of the upper support structure: After the bottom diagonal rods 4 are installed, the adjacent bottom support structure disc truss units are connected into a whole with horizontal rods 2, and then the above steps are repeated to build the upper support structure to the designed height;

[0072] S7. Installing the top-level adjustable support 5: Install the adjustable support 5 on the top of the vertical pole 3 of the upper support structure. Place the steel main keel 9 supporting the formwork on the adjustable support 5. Build multiple groups of wooden secondary keels 10 on the steel main keel 9 to assist in the slab construction support operation.

[0073] S8. Install the shelving beam support system: first install the beam, and use the cross-sectional characteristics of the steel frame 6 (the steel frame 6 can be made of H-shaped steel, channel steel, or I-shaped steel) to fix the steel frame 6 between two sets of vertically parallel vertical poles 3 through the fixing clamp 8. Install the adjustable support 2 7. The lifting screw 73 with a diameter of Ф38 is vertically inserted into the support 71. The length of the lifting screw 73 extending from the top shall not be greater than 400mm.

Adjust the overall lifting height of the adjustable support 2 7 so that the steel main keel 9, the wooden secondary keel 10, and the formwork can be adjusted in height together to achieve precise adjustment of the formwork elevation.

[0074] S9. Formwork installation: Determine the size of the formwork arch based on the beam span: no arching is considered for beams <4m; 4m ≥ L> 12m, the arching is 2‰ of the span; L ≥ 12m, the arching is 3‰ of the span; cantilever components are arched at 4‰ of the span;

[0075] S10. Precautions for erection: All components should be installed according to the design and relevant regulations of the buckle frame; the on-site foundation should be cleaned before construction; the frame elevation and position should be adjusted by adjusting the vertical poles and horizontal poles according to the actual situation on site to ensure that the support requirements of the frame are met; during the erection process, attention should be paid to adjusting the verticality of the frame, requiring the verticality of the entire frame to be less than 1 / 500L, and the maximum allowable deviation is 50mm; when erecting or changing the operating procedures, unrelated personnel are prohibited from entering the dangerous area; according to the needs of on-site construction, a pedestrian passage is set up around the structure, and the outside of the passage is covered with a dense mesh net and reliably connected to the frame; a horizontal scissors brace is set every 4-6 steps of the frame, and the width of the scissors brace is 4-6m, and the safety flat net is arranged according to the number of scissors brace layers.
