Description

Technical Field

[0001] The present application relates to the field of construction, and in particular to a foldable full-floor supporting scaffold and a frame assembly and erection method. Background Art

[0002] In the field of construction engineering, scaffolding is a working platform set up to ensure the smooth progress of each construction process. According to the location of the scaffolding, it can be divided into external scaffolding and internal scaffolding; according to the purpose of use, it can be divided into working scaffolding and supporting scaffolding; according to different materials, it can be divided into wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding; according to the structural form, it can be divided into pole scaffolding, bridge scaffolding, door scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, climbing scaffolding, etc.

[0003] As a kind of supporting scaffolding, full-height supporting scaffolding is widely used in the construction process of cast-in-place concrete structures in house construction, municipal roads, bridge and tunnel projects.

[0004] As for the full-height support scaffolding used in the existing cast-in-place concrete structure wooden formwork, the common ones are disc-type full-height support scaffolding, bowl-type full-height support scaffolding, wheel-type full-height support scaffolding, steel pipe fastener full-height support scaffolding, etc. Its main erection steps are as follows: Figure 1 As shown, the following steps are included: construction preparation, laying of gaskets, bases and sweeping rods, placement of gaskets, erection of bases and sweeping rods, laying of vertical poles and second-step horizontal poles, erection of vertical poles, erection of second-step horizontal poles, laying of vertical poles and third-step horizontal poles, extension of vertical poles, erection of third-step horizontal poles, repeated erection to the designed height of the frame, reinforcement of diagonal braces and shear braces, installation of top supports, and hanging of horizontal anti-fall nets.

[0005] The steps for dismantling the existing full-floor supporting scaffolding are as follows: Figure 2 As shown, the following processes are included: dismantling preparation work, lowering the height of the top support, dismantling the inner back ribs of the top support, dismantling the top horizontal bars and diagonal bars, dismantling the top support and the top vertical bars, dismantling the next layer of horizontal bars and diagonal bars, dismantling the next layer of vertical bars, repeating the dismantling to the bottom layer of the frame, material sorting, hoisting and transportation.

[0006] From the main erection and dismantling construction steps of the aforementioned disc buckle type, bowl buckle type, wheel buckle type, and steel pipe fastener type full-floor support scaffolding, it can be seen that the construction process has the following deficiencies: 1. There are many loose parts of scaffolding poles, cross bars, diagonal bars and other materials. The material hoisting, transportation and laying process during erection, as well as material sorting, hoisting and transportation during dismantling are very labor-intensive and the construction efficiency is low. 2. Due to the large number of loose parts of scaffolding uprights, crossbars, diagonal bars and other materials, there are many nodes connecting the bars. During the erection and dismantling of the frame, each connection node needs to be manually disassembled and assembled, which results in a large amount of disassembly and assembly work and low construction efficiency. 3. Except for the erection and dismantling of the bottom frame, which can be done on the ground or floor, during the erection and dismantling of the second and higher frames, the workers need to walk back and forth on the scaffolding frame, which has low erection efficiency and a greater safety risk of falling from heights.

DETAILED DESCRIPTION

[0026] The specific implementation methods of the present application are described below in conjunction with the accompanying drawings so that those skilled in the art can better understand the present application.

[0027] In order to clearly describe the technical solution and working principle of this application, the following contents of this application are explained and set: The first direction is the X direction, the second direction is the Y direction, plane a is a plane formed by two adjacent poles along the X direction coordinate line, plane b is a plane formed by two adjacent poles along the Y direction coordinate line, plane a and plane b intersect in space, preferably, X and Y are perpendicular, and plane a and plane b are perpendicular to each other. Example

[0028] like Figure 3As shown, a foldable full-floor support scaffolding frame unit is provided, comprising a first upper upright bar 11 and a first lower upright bar 21 which can be spliced ​​and connected to the first upper upright bar 11, a second upper upright bar 12 and a second lower upright bar 22 which can be spliced ​​and connected to the second upper upright bar 12; a first slider 31 arranged on the first lower upright bar 21, and a second slider 32 arranged on the second lower upright bar 22, wherein the first slider 31 can slide along the first lower upright bar 21, and the second slider 32 can slide along the second lower upright bar 22; And a first diagonal rod 41 and a second diagonal rod 42, one end of the first diagonal rod 41 is hinged to the second upper vertical rod 12, and the other end is connected to the first slider 31, one end of the second diagonal rod 42 is hinged to the first upper vertical rod 11, and the other end is connected to the second slider 32, the first upper vertical rod 11 and the first lower vertical rod 21 constitute a first vertical rod, the second upper vertical rod 12 and the second lower vertical rod 22 constitute a second vertical rod, the first diagonal rod 41 and the second diagonal rod 42 intersect in the middle of the first vertical rod and the second vertical rod and are hingedly connected at the intersection.

[0029] like Figures 5 and 6 As shown, Figure 3 The foldable full-floor support scaffolding is a basic unit, and a plurality of such scaffolding units are arranged in sequence. Since the first vertical pole, the second vertical pole, the first diagonal pole, the second diagonal pole and the first slider and the second slider in each scaffolding unit form a parallelogram, a row of foldable and retractable frames can be formed by utilizing the instability of the parallelogram. Figure 5 This is the state before folding. Figure 6 In the folded state.

[0030] like Figure 4 As shown, the first slider 31 and the second slider 32 are in the shape of steel tubes, a through hole 35 is opened on the annular surface of the steel tube, and a nut 36 is arranged at the through hole 35 (see Fig. 22 ).

[0031] like Figures 7 and 8 As shown, a fastening clamp 5 is provided, which is composed of a horizontal screw rod 51 and a vertical handle 52. The horizontal screw rod 51 is threadedly connected with the nut 36 on the slider. Figure 5 When the multiple continuous scaffolds are fixed, the fastening clamps 5 are used to lock the slider on each vertical pole. At this time, in each foldable full-floor supporting scaffolding unit, the first vertical pole, the second vertical pole and the first diagonal pole, the second diagonal pole form a triangular hinged body. According to the self-stabilizing characteristics of the triangle, the multiple continuous scaffolds form a stable truss structure.

[0032] like Fig. 9 As shown, a row of stable truss structures is formed by multiple continuous scaffolds after each slider is locked by a fastening clamp 5.

[0033] The full-height support scaffolding in the project needs to be combined into a frame structure in multiple rows and columns. In order to avoid cross interference in the X and Y directions when the foldable full-height support scaffolding described in the present application is used as a basic unit for assembly operations, two sliders are set at the lower uprights of each scaffolding unit.

[0034] like Figures 10 to 12 As shown, each upright has adjacent uprights in the X and Y directions in the entire frame structure. If there is only one slider on each upright, the folding function of the full-height support scaffolding of the present application can only be realized within one plane. If the folding function of the full-height support scaffolding needs to be realized in both the X and Y directions, it can be achieved by setting two sliders on each upright.

[0035] like Fig.11 As shown, a set of structural diagrams of two planes intersecting in the X direction and the Y direction are provided. According to the above description and setting, it can be known that the plane where the three vertical poles arranged in the X direction are located is plane a, and the plane where the three vertical poles arranged in the Y direction are located is plane b. The vertical pole at the intersection of plane a and plane b is recorded as the first vertical pole 61, the vertical pole adjacent to the first vertical pole 61 on plane a is recorded as the second vertical pole 62, and the vertical pole adjacent to the first vertical pole 61 on plane b is recorded as the third vertical pole 63. Two sliders are set on the lower vertical pole of each vertical pole. The two sliders at the lower vertical pole of the first vertical pole 61 are recorded as the first slider 31 and the third slider 33, and the two sliders at the lower vertical pole of the second vertical pole 62 and the lower vertical pole of the third vertical pole 63 are both the second slider 32 and the fourth slider 34. By Fig.11 It can be seen that the first slider 31 on the lower vertical rod of the first vertical rod 61 is connected to the upper vertical rod of the second vertical rod 62 on plane a, and the third slider 33 on the lower vertical rod of the first vertical rod 61 is connected to the upper vertical rod of the third vertical rod 63 on plane b; similarly, the second slider 32 at the lower vertical rod of the second vertical rod 62 is connected to the upper vertical rod of the first vertical rod 61 on plane a, and the fourth slider 34 at the lower vertical rod of the second vertical rod 62 is connected to the upper vertical rod of the vertical rod adjacent to it on a plane parallel to plane b and passing through the second vertical rod 62 ( Fig.11 By analogy, the third vertical rod 63 is also connected to the adjacent vertical rods on the two intersecting surfaces in the same way.

[0036] like Fig.12 As shown, the frame structure is formed after being assembled by the above method, and this frame structure can be unfolded and folded along the X direction and the Y direction at the same time.

[0037] like Figure 10 to Figure 11 As shown, the vertical poles in the frame unit are divided into corner vertical poles A, end vertical poles B and middle vertical poles C according to their different positions in the frame (see Fig.11), the corner pole A is connected to two adjacent poles on plane a and plane b; the end pole B is connected to two adjacent poles on plane a (or plane b), and is also connected to an adjacent pole on plane b (or plane a); the middle pole C is connected to two adjacent poles on plane a and plane b respectively. The poles at these three different positions have different connection point structures on the corresponding upper poles and lower poles, specifically: like Fig.13 and Fig.14 As shown, Fig.13 The upper upright of the corner upright A is shown, on which two hinge points 13 are arranged, corresponding to the upper upright. Fig.14 The figure shows the lower upright of the corner upright A, on which two sliders are arranged, each slider being provided with a connecting ear plate 37. Preferably, the connecting ear plates 37 on the two sliders are installed at perpendicular positions to each other, so that the corner upright A can be connected to the two adjacent uprights on plane a and plane b; like Fig.15 and Fig.16 As shown, Fig.15 The upper upright of the end upright B is shown, on which three hinge points 13 are arranged, corresponding to the upper upright. Fig.16 The figure shows the lower upright of the end upright B, on which two sliders are arranged, one of which is provided with a connecting ear plate 37, and the other is provided with two connecting ear plates 37, the connecting ear plates 37 on the two sliders are installed at perpendicular positions to each other, and the two connecting ear plates 37 arranged on the same slider are in the same plane, so that the end upright B can be connected to two adjacent uprights on plane a (or plane b), and connected to one adjacent upright on plane b (or plane a) at the same time; like Fig.17 and Fig.18 As shown, Fig.17 The upper upright of the middle upright is shown, on which four hinge points 13 are arranged, corresponding to the upper upright. Fig.18 The figure shows the lower upright of the middle upright, on which two sliders are arranged. Two connecting ear plates 37 are arranged on each slider. The two connecting ear plates 37 on each slider are in the same plane. The connecting ear plates 37 on the two sliders are installed at perpendicular positions to each other, so that the middle upright C can be connected with two adjacent uprights on plane a and plane b.

[0038] The upper end of the first oblique rod 41 or the second oblique rod 42 is hinged to the hinge point 13. The connecting ear plate 37 is a semicircular thin plate. A hinge hole 371 is provided on the semicircular thin plate. The hinge hole 371 is a through hole. The end of the first oblique rod 41 or the second oblique rod is hinged to the hinge hole 371.

[0039] like Figures 19 to 23 As shown, further, a method for assembling the above-mentioned foldable full-floor supporting scaffolding frame is provided, comprising the following steps: Step S01: Fig.19 As shown, according to the length and width requirements of the frame to be erected, take an appropriate number of first upper vertical rods 11, second upper vertical rods 12, first lower vertical rods 21, second lower vertical rods 22, first sliders 31, second sliders 32, third sliders 33, fourth sliders 34, first diagonal rods 41, and second diagonal rods 42, and place them on the ground; Step S02: hinge one end of the first oblique rod 41 to the second upper vertical rod 12; hinge one end of the second oblique rod 42 to the first upper vertical rod 11; Step S03: connecting the other end of the first inclined rod 41 to the first slider 31 , and connecting the other end of the second inclined rod 42 to the second slider 32 ; Step S04: intersecting the first oblique rod 41 and the second oblique rod 42 and hingedly connecting them at the intersection; Step S05: The first lower upright bar 21 is connected to the first upper upright bar 11 through the first slider 31 and the third slider 33; the second lower upright bar 22 is connected to the second upper upright bar 12 through the second slider 32 and the fourth slider 34, so as to assemble a foldable full-floor support scaffolding frame unit; Step S06: Fig. 20 As shown, repeat steps S01-S05 to assemble five consecutive foldable full-floor support scaffolding frame units along the X direction; like Fig.21 and Fig. 22 As shown, then along the Z direction, 6 layers of 5 consecutive foldable full-floor support scaffolding frame units are set up, among which Fig.21 This is a schematic diagram of assembling the first vertical pole of the second floor. Fig. 22 This is a schematic diagram of assembling to the second pole of the second layer. At this time, the first frame unit of the second layer has been formed. By analogy, it is finally assembled into a 5*6 specification foldable full-floor support scaffolding frame (see Fig.23 ).

[0040] If the frame needs to be disassembled, it can be disassembled in whole or in part according to the sequence of steps S06-S01.

[0041] Further, if Figure 24 to Figure 26 , providing a method for erecting a foldable full-floor supporting scaffolding frame, The following steps are involved: Step M01: Fig.24 As shown, the frame is hoisted to the location to be installed using a hoisting device, and positioning lines are set in advance at the location to be installed according to the requirements of the erection. The positioning lines include a positioning line dx parallel to the X direction, a positioning line dy parallel to the Y direction, and a corner positioning line dj. One corner of the frame is set at the positioning line dj. Step M02: Fig.25As shown, use the transport equipment to lift up one end of the frame, loosen the sliders on each supporting scaffold in the X direction one by one from the corner positioning line dj, move the transport equipment to gradually unfold the frame along the X direction until the Y direction edge positioning line dy, and then lock each loosened slider with a fastening clamp; Step M03: Similarly, use the transport equipment to lift the other end of the frame, loosen the sliders on each supporting scaffold in the Y direction one by one from the corner positioning line dj, move the transport equipment to gradually unfold the frame along the Y direction until the X-direction edge positioning line dx, and then lock each loosened slider with a fastening clip. At this time, the entire frame has been unfolded and fixed according to the erection requirements (see Fig.26 ); Step M04: according to the construction requirements, other rod structures are set up on the frame, and a top support is installed on the top of the frame; Step M05: Install the back ribs and formwork on the top support to complete the frame erection.

[0042] Furthermore, a method for dismantling a foldable full-floor support scaffolding frame is provided, comprising the following steps: First, loosen the top support of the frame, pull out the inner template and back rib of the top support, as well as other rod structures on the frame; Secondly, loosen the fastening clamps of the sliders in the X direction (or Y direction) of the frame, fold the frame along the X direction (or Y direction), and after folding, lock the corresponding sliders in the X direction (or Y direction) with the fastening clamps; Finally, loosen the fastening clamps of the sliders in the Y direction (or X direction) of the frame, fold the frame along the Y direction (or X direction), and after folding, lock the corresponding sliders in the Y direction (or X direction) with the fastening clamps.

[0043] The frame described in this application can be used repeatedly in different construction projects. The turnover method of the frame is as follows: (1) Use forks and other equipment to lift both ends of the frame at the same time and to a certain height from the ground. Since the diagonal bars in the X and Y directions are in a fastened state, the entire frame is a statically determinate structure and the frame will be lifted as a whole; (2) After all the vertical poles of the entire frame are off the ground, use a fork to drag the frame out from under the floor; (3) Determine whether it is necessary to adjust the number of foldable full-height support scaffolding basic units in the X and Y directions of the frame according to the size of the frame to be erected in the next construction section; (4) When the number of basic units needs to be adjusted, the frame is first transported to the assembly site as a whole, assembled or disassembled according to the above frame assembly and disassembly methods, and then transported to the next construction area and used in rotation according to the above installation and disassembly construction methods; (5) When there is no need to adjust the assembly quantity of the basic frame unit, the frame as a whole is directly transported to the next construction area and used in rotation according to the aforementioned installation and dismantling construction methods.

[0044] The turnover frequency of full-height support scaffolding in engineering is very high. The use of the foldable full-height support scaffolding described in this application can greatly save the time of assembling and dismantling the scaffolding and increase the turnover frequency. Example

[0045] The main difference between the second embodiment and the first embodiment is that the second embodiment uses a disc-shaped oblique rod. The disc-shaped oblique rod is a common node connector, which is mainly assembled by connecting a circular disc, a pull rod plug and a pin, and can be used to connect rods. The end of the disc-shaped oblique rod becomes thinner from thick.
