Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly relates to a formwork support frame erection structure of the socket - and - spigot type and its construction method. Background Art

[0002] With the rapid development of the construction industry, the requirements for the construction efficiency and safety of workers are increasing day by day. The traditional support system has been difficult to meet the needs of modern construction in some aspects. Among them, the socket - and - spigot formwork support frame has been widely used in the field of building construction due to its outstanding advantages of high erection efficiency and strong load - bearing capacity. For example, in the construction of nuclear power projects, the erection of the formwork support frame is particularly important.

[0003] During the building construction process using the socket - and - spigot formwork support frame, the formwork support frame supports the formwork by jacking it up to the same horizontal height (this method can be called slab construction operation). However, in the actual construction process, the formwork support frame not only needs to support the slab construction formwork, but also needs to support the cross - beam formwork that is not at the same height as the slab construction. (The operation of supporting the cross - beam formwork is called beam construction). The load - bearing beam formwork has an inverted "U" - 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 re - erect a new support structure, and if necessary, disassemble and reorganize the support structure that has been erected for the slab construction, resulting in low construction efficiency and great disadvantages.

[0014] In order to solve the above technical problems, the present invention also provides a construction method for setting up a disc-type formwork frame structure, comprising the following steps: S1. Measurement and layout: Before installation, lay out the bottom plate and floor slab according to the layout drawing, set up the frame according to the designed position, check whether the layout points are correct, and arrange the layout according to the type of components supporting the concrete structure. Clearly mark the drop-down area, large-section beams, and hanging components on the foundation ground to facilitate the frame support in one step and avoid additional reinforcement; S2. Construction of bottom support structure: Material preparation personnel distribute materials according to the required number of scaffolding and deliver them to each scaffolding area. They set up the adjustable base according to the position of each fulcrum and pull up the horizontal rod to fix it. The height of the horizontal rod from the ground should not exceed 550mm. The adjustment position should be correctly placed according to the construction drawing of the formwork support frame. S3. Install the bottom poles: Install the poles required for the bottom support. The length range is 3m / 2m / 1.5m, which is selected according to the overall installation height, and the middle joints of the poles are staggered; S4. Installation of horizontal rods: 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. S5. Install the bottom diagonal rods: assemble the diagonal rods in a clockwise or counterclockwise direction. First, insert the diagonal rods into the large-size limiting holes on the connecting plate, so that the front end of the diagonal rods is against the vertical rod round tube, and then use the pin plate to penetrate the large-size limiting holes and tighten them. The diagonal rods have directionality and cannot be overlapped if the direction is opposite; S6. Installation of the upper support structure: After the bottom layer of diagonal rods is installed, the adjacent bottom support structures are connected into a whole by horizontal rods, and then the above steps are repeated to build the upper support structure to the designed height; 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, and build multiple groups of wooden secondary keels on the steel main keel in sequence to assist in the support operation of the board construction; S8. Install the shelving beam support system: first install the beam, and use the characteristics of the steel frame cross section to fix the steel frame between two sets of vertically parallel vertical poles through a fixing fixture, and install the adjustable support No. 2. The lifting screw with a diameter of Ф38 is vertically inserted into the support tube. The length of the lifting screw extending from the top shall not be greater than 400mm. During installation, the upper and lower parts should be concentric, and the notches of the bracket should be in the same direction. Place the steel main keel on the lifting screw, and build multiple sets of wooden secondary keels on the steel main keel in sequence to support the beam formwork, and adjust the overall lifting height of the adjustable support No. 2 so that the height of the steel main keel, the wooden secondary keel and the formwork can be adjusted together to achieve precise adjustment of the formwork elevation; S9. Formwork installation: The size of the formwork arch is determined according to the beam span: if the beam is less than 4m, no arch is considered; if the beam is 4m or greater than L>12m, the arch is 2‰ of the span; if the beam is L≥12m, the arch is 3‰ of the span; and if the beam is cantilevered, the arch is 4‰ of the span. S10. Precautions for erection: All components should be installed according to the design and relevant regulations of the coiled 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 procedure, 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, the outside of the passage is covered with dense mesh, and it is reliably connected to the frame; a horizontal scissors brace is set every 4-6 steps of the frame, the width of the scissors brace is 4-6m, and the safety flat net is arranged with the number of scissors brace layers.

[0015] Beneficial effects of the present invention: 1. The beam construction is supported by setting up a shelving cross-beam support system, and the shelving cross-beam support system is directly built on the upper half of the plate support system, and can be directly combined with the plate support system required for the plate construction operation to form an integrated whole. The two 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.

[0016] 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.

[0017] 3. The connection between the crossbeam support system and the slab support system is carried out through two sets of symmetrically arranged fixed jigs. Each set of fixed jigs can apply an inward clamping and fixing force from the front and rear through two sets of clamping components arranged on the front and rear sides. The two sets of symmetrically arranged fixed jigs can apply an inward clamping and fixing force from the left and right through two sets of abutting components in a symmetric positional relationship. The disk buckle applies an upward supporting force to the steel frame from bottom to top. Thus, by applying the 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.

Detailed implementation manners

[0032] To make the above - mentioned objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0033] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from this description. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0034] Embodiment 1 Refer to Figures 1 to 12, which is the first embodiment of the present invention, includes a formwork support structure with button locks, including a slab support system and a supporting beam support system. The supporting beam support system includes two sets of symmetrically arranged steel frames 6, two sets of adjustable supports II 7 vertically inserted into the two steel frames 6, and two sets of fixed clamps 8 symmetrically arranged at both ends of the steel frames 6; The fixed clamp 8 includes a fixing component 81 abutting against one end of the steel frame 6. Chute grooves 812 are formed on both sides of the fixing component 81. A driving component 82 is inserted into the axial center position of the fixing component 81. A driven component 83 is rotatably connected to the driving component 82. A scroll rack 833 with a scroll structure is arranged on the inner side of the driven component 83. A clamping component 84 in an L-shaped structure is inserted into the chute groove 812. Multiple groups of teeth 844 are spirally distributed on one side of the clamping component 84. At the same time, the teeth 844 are meshed and driven with the scroll rack 833. An abutting component 85 is horizontally threadedly connected to the axial center position of the fixing component 81. One end of the abutting component 85 extends into the driving component 82. And a connecting component 86 is arranged on one end of the abutting component 85 located inside the driving component 82.

[0035] Among them, referring to Figure 5 , the fixing component 81 includes a fixing base 811. The chute grooves 812 are vertically offset and parallelly arranged on the fixing base 811. A limiting block 813 is arranged inside the end of the chute groove 812. A sleeve 814 fixedly connected to one side of the axial center position of the fixing base 811. And a connecting shaft 815 arranged at the outer end of the sleeve 814. The abutting component 85 is threadedly connected to the connecting shaft 815. The fixing base 811 is used for installing the fixing component 81, the clamping component 84 and the abutting component 85. The chute groove 812 and the limiting block 813 cooperate to enable the clamping component 84 to only translate and slide along the chute groove 812 and cannot be separated from the fixing component 81.

[0036] Among them, referring to Figure 4, the driving component 82 includes a driving shaft 821 inserted into the axial center position of the fixed seat 811, a first limiting ring 822 fixedly arranged on the driving shaft 821, a relief groove 823 opened in the driving shaft 821, a first gear ring 824 sleeved on the driving shaft 821, a bolt 826 arranged at the outer end of the driving shaft 821, and a first spring 825 sleeved on the driving shaft 821 and located between the first gear ring 824 and the bolt 826. The driving component 82 is limited on the fixed component 81 by the first limiting ring 822 and can perform axial rotation with an unchanged position at the axial center position of the fixed component 81. The first gear ring 824 is always in clamping engagement with the second gear ring 832 through the elastic support of the first spring 825. At this time, when the driving component 82 rotates, it can drive the first gear ring 824 to rotate synchronously. The bolt 826 has a common hexagonal bolt structure, and a wrench can drive the driving component 82 to rotate through the bolt 826. The runner arranged at the end of the driving shaft 821 can also drive the driving component 82 to rotate. The relief groove 823 is used to accommodate and install the connecting component 86.

[0037] Further, a section of the driving shaft 821 where the first gear ring 824 is sleeved is rectangular, and a section of the driving shaft 821 penetrating into the driven component 83 is cylindrical. A rectangular notch matching the rectangular section is opened in the first gear ring 824. Therefore, while the first gear ring 824 rotates circumferentially following the driving shaft 821, it can also slide horizontally along the rectangular section of the driving shaft 821.

[0038] Among them, referring to Figure 6 and Figure 10 , the driven component 83 includes a turntable 831 sleeved on the driving shaft 821, a scroll rack 833 fixedly connected to the inner side of the turntable 831, and a second gear ring 832 fixedly connected to the outer side of the turntable 831. The second gear ring 832 is in clamping engagement with the first gear ring 824. The scroll structure of the scroll rack 833 makes the transition between its outermost end and innermost end smooth. An object moving along its scroll direction will gradually move away from or approach the center of the scroll rack 833. The away or approach movement is driven according to the overall rotation direction of the scroll rack 833. The clamping engagement between the second gear ring 832 and the first gear ring 824 enables the driving component 82 to synchronously drive the entire driven component 83 to rotate when rotating.

[0039] Among them, referring to 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 clamping plate 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 clamping plates 843 at both ends of the clamping component 84 are parallel to the steel frame 6. The slot 842 can ensure that the slide bar 841 moves normally along the slide groove 812 while not being separated from the fixed component 81 by cooperating with the limit block 813. 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 tooth 844 will be cut into its spiral path. Since the slide rod 841 is limited by the slide groove 812, the spiral rack 833 will push the tooth 844 to move when it rotates, and the moving tooth 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 relatively 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.

[0040] Among them, refer to 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 provided 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 can continue to extend and retract at the axial position of the fixed component 81 through the threaded connection with the connecting shaft 815, and the limiting groove 852 can ensure that the extension screw 851 does not disengage from the circumferential limit between the plug block 862 when moving in the horizontal direction.

[0041] Among them, refer to 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, a gear ring 4 863 sleeved on the extension screw 851, and the gear ring 4 863 is engaged with the gear ring 3 861, and a limiting ring 2 865 sleeved 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 two 865. The gear ring three 861 is limitedly connected to the extension screw 851 in the circumferential direction through the plug 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 plug block 862 are clamped together, and the two sides of the gear ring four 863 are provided with extension blocks 8631 (such as Figure 9 As shown in the figure, the driving shaft 821 is also provided with a sliding groove 8211 which matches it. The extension block 8631 cooperates with the sliding groove 8211, so that the gear ring four 863 and the driving shaft 821 can limit each other in the circumferential direction, thereby allowing the two to 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, thereby allowing the extension screw 851 to perform a telescopic action through the threaded drive of the connecting shaft 815.

[0042] Among them, refer to Figure 11 The adjustable support 7 includes a support tube 71 inserted into the two groups of steel frames 6, a rectangular plate 72 arranged horizontally on the support tube 71, a lifting screw 73 inserted into the top of the support tube 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 tube 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 with the adjusting wrench 75, and the adjusting wrench 75 is limited and rotated at the top of the support tube 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 tube 71. Therefore, the lifting screw 73 is limited in the circumferential direction of the support tube 71 and can be displaced in the vertical direction along the support tube 71.

[0043] Among them, refer to Figure 1, the formwork support system includes multiple groups of adjustable bases 1 distributed in parallel in the vertical direction, horizontal bars 2 horizontally erected between every two groups of adjustable bases 1, vertical poles 3 vertically connected above each group of adjustable bases 1, diagonal bars 4 diagonally erected between the vertical poles 3, and adjustable supports 5 arranged at the tops of the vertical poles 3. Vertical poles 3 are provided on each component of the adjustable base 1, horizontal bar 2, vertical pole 3, diagonal bar 4, and adjustable support 5, and the five are all connected through connection plates 31. The connection plates 31 are provided with limit holes of different sizes. The adjustable support 5 and the adjustable support 7 have the same structure, so they can operate in the same way.

[0044] Furthermore, referring to Figure 8 and Figure 9 , the first gear ring 824 and the second gear ring 832 are matched through triangular teeth. When the torque force between the two is large, the beveled edges of the teeth will guide the two meshing teeth outward, causing them to move horizontally, and then resulting in dislocation, so that the first gear ring 824 and the second gear ring 832 no longer engage in transmission. The same is true for the fourth gear ring 863 and the third gear ring 861.

[0045] In summary, combining Figure 1 and Figure 12 , when building the support structure of the disk buckle formwork support, two steel frames 6 are fixed between two vertical poles 3 that are parallel to each other in the vertical direction, and the two steel frames 6 are respectively located on both sides of the vertical poles 3. At the same time, the lower parts of the two steel frames 6 are supported by the connection plates 31. The driving component 82 drives the first gear ring 824 to rotate. The rotating first gear ring 824 drives the driven component 83 to rotate through the engagement with the second gear ring 832. The rotating driven component 83 drives the teeth 844 through the scroll rack 833, so that the teeth 844 drive the clamping component 84 to slide horizontally along the chute 812, so that the clamping component 84 abuts against and approaches the steel frame 6 from the side. The two clamping components 84 move synchronously in opposite directions of movement, and can clamp the two steel frames 6 from the front and back sides (as Figure 8 shown), applying the limiting force from the front and back sides. After the clamping component 84 clamps in place, the immovable clamping component 84 limits the scroll rack 833 in the reverse direction, so that the whole driven component 83 cannot move, while the driving component 82 continues to rotate. At this time, the torque force 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 component 82 no longer drives the driven component 83 to rotate; While the driving member 82 rotates, the fourth toothed ring 863 synchronously rotates following the driving member 82. The rotating fourth toothed ring 863 drives the extension screw 851 to rotate through the third toothed ring 861. The rotating extension screw 851 will extend from the connecting shaft 815 and finally jack up the top plate 853 to abut against the side surface of the vertical rod 3. With the cooperation of the clamping and limiting of the clamping member 84, the abutting member 85 can apply a clamping force from the side. Since two sets of fixed clamps 8 are installed at both ends of the steel frame 6, there will be two sets of abutting members 85 applying clamping and limiting forces from the left and right sides (as Figure 7 shown); Whether the clamping member 84 clamps in place first or the abutting member 85 abuts in place first, after either of them completes the specified work, they will stop in time without interfering with the continued stable progress of the other, thereby improving the flexibility of the device; In summary, combined with Figure 7 it can be seen that through the limiting and supporting from the front and back sides, left and right sides, and below, the force of limiting, fixing, and clamping can be applied in multiple directions and positions, effectively ensuring the intimacy and stability of the connection between the two plate support systems and the supporting beam support system, thereby improving the installation stability of the overall structure.

[0046] Furthermore, after the supporting beam support system is built in the upper half area of the plate support system through the fixed clamp 8, the supporting beam support system can support the beam construction, and the supporting beam support system is directly combined with the plate support system required for the plate construction operation to form an integrated structure. The two jointly use the lower part of the plate support system for load support. The load transfer of the two is as Figure 13 shown. Compared with the prior art, the supporting beam support system is directly combined with the plate support system, eliminating the need to additionally build the bottom support structure of the beam support system, achieving the purpose of saving building materials and shortening the construction and installation period.
