Detailed Description
The invention will be further elucidated and described with reference to the drawings and the detailed description. The technical features of the embodiments of the present invention can be combined correspondingly without mutual conflict.
The size of the existing construction operation platform is usually fixed and cannot be temporarily adjusted according to actual construction requirements, so that the transition use of the construction operation platform is greatly limited. As shown in fig. 1, the state of the construction work platform a when the transverse span is insufficient is shown, and at this time, the length of the transverse steel beam of the platform itself is insufficient and is smaller than the span between the two external longitudinal steel beams B. As shown in fig. 2, the state of the construction work platform a when the longitudinal span is insufficient is shown, and at this time, the length of the transverse steel beam of the platform itself is insufficient and is smaller than the span between the two external transverse steel beams C. Because the external longitudinal steel beams B and the external transverse steel beams C are generally not allowed to be changed, when the situation occurs, the work platform a can only be replaced again in the prior art.
In a preferred embodiment of the present invention, an adjustable super high-rise steel structure construction work platform is provided, which can better solve the above two problems.
The super high-rise steel structure construction operation platform consists of a bearing frame and an enclosure structure 4, as shown in figure 3, basic components of the super high-rise steel structure construction operation platform comprise a transverse support beam 1, a longitudinal support beam 2, a rotation adjusting component 3, the enclosure structure 4, a support plate 5 and a keel 6, and specific forms of the two parts are described below.
As shown in fig. 4, the bottom of the force-bearing frame is enclosed by two transverse support beams 1 and two longitudinal support beams 2 to form a rectangular outer frame, and the two transverse support beams 1 and the two longitudinal support beams 2 play a role in bearing the whole weight and are used for transmitting the load of the upper part to an external longitudinal steel beam B or an external transverse steel beam C. The enclosing structure 4 is fixed on the rectangular outer frame, the enclosing structure 4 can be formed by splicing a plurality of rod pieces, a passage for people to enter and exit is formed in one side of the enclosing structure, and auxiliary facilities such as a separation net and the like can be further wrapped outside the rod pieces to prevent falling objects. The external longitudinal steel beams B and the external transverse steel beams C are typically cantilever steel beams in a super high-rise steel structure, and it should be noted that the external longitudinal steel beams B and the external transverse steel beams C are named only with respect to the position of the working platform a in the present invention for convenience of description. There is no difference in the longitudinal and transverse directions for the super high-rise steel structure itself.
A plurality of transverse and longitudinal staggered keels 6 are laid in the rectangular outer frame, and supporting plates 5 are laid above the keels 6 in a tiled mode. In general, the support plate 5 should be spread over the upper surface of the rectangular outer frame to serve as a support for the constructors and equipment. The adjustment between the work platform a and the outer longitudinal steel beam B is achieved by stretching the adjustment member, and the adjustment between the work platform a and the outer transverse steel beam C is achieved by rotating the adjustment member.
Referring to fig. 5, a specific form of the rotation regulating member 3 is shown. The 4 rotating adjusting components 3 are respectively installed and fixed on four corner points of the rectangular outer frame. Each rotation adjusting member 3 includes first girder steel 301, second girder steel 302 and third girder steel 303, and wherein first girder steel 301 vertical fixation is on the rectangle frame, can the beading in the 1 side of horizontal supporting beam during actual installation, and first girder steel 301 is the channel-section steel, and its notch orientation is unanimous with longitudinal support beam 2 extending direction, and its orientation should deviate from work platform A, towards the outside. Third girder steel 303 one end articulates in the fluting of first girder steel 301, and the other end of third girder steel 303 articulates with the one end of second girder steel 302, and third girder steel 303 can be round with the pin joint free rotation between the first girder steel 301, make second girder steel 302 and third girder steel 303 can fold and get into in the fluting of first girder steel 301. The second steel beam 302 and the third steel beam 303 are completely folded in the first steel beam 301 as shown in fig. 7, and the rotation adjusting member 3 is integrally contracted and does not function to expand the size of the platform. In order to maintain the fixed positions of the second steel beam 302 and the third steel beam 303, a temporary fixing member may be provided on the top of the first steel beam 301, and when the second steel beam 302 and the third steel beam 303 are both folded in the groove of the first steel beam 301, the other end of the second steel beam 302 may be temporarily fixed by the temporary fixing member. The temporary fixing may be implemented by a pin, that is, as shown in fig. 7, the second steel beam 302 and the third steel beam 303 are vertically fixed in the groove of the first steel beam 301 by a pin passing through the other end of the second steel beam 302 and the pin hole at the top of the first steel beam 301. Of course, the form of the temporary fixing member can be multipurpose, and can be completely realized by other clamping members. When the longitudinal span of the working platform a is insufficient, the rotation adjusting member 3 needs to be unfolded to increase the length of the two longitudinal support beams 2, and the unfolded rotation adjusting member 3 is shown in fig. 6. Under this expansion state, need fix the other end of second girder steel 302, therefore mated shaft hole has all been seted up at the other end of second girder steel 302 and the middle part of first girder steel 301. When the third steel beam 303 rotates to a horizontal state, the shaft hole of the second steel beam 302 is just coaxial with the shaft hole of the middle part of the first steel beam 301, and the other end of the second steel beam 302 is detachably fixed with the first steel beam 301 through the fixing pin 304. Thereby, the length of the two longitudinal support beams 2 can be extended by turning the deployment of the adjustment member 3. As shown in fig. 8 and 9, the work platform a can be stably erected on the outer transverse steel beams C by four unfolded rotation regulating members 3, thereby solving the problem in fig. 2 and expanding the applicable range of the work platform a.
In the rotation adjusting member 3, the second steel beam 302 may be an angle steel, and the third steel beam 303 may be a channel steel.
In addition, for the expansion of the platform size in the transverse direction, the invention is solved by providing four tension adjusting members. While the tension adjustment member is realized by means of a transverse supporting beam 1. As shown in fig. 10 and 11, the main body of the transverse support beam 1 is a square steel pipe 101, and a telescopic steel pipe 102 is inserted into each of both ends of the square steel pipe 101. The telescopic steel pipe 102 is also a square steel pipe, but the cross section size is smaller than that of the square steel pipe 101. The telescopic steel pipe 102 and the square steel pipe 101 form a sliding pair, and can extend out of or retract into the square steel pipe 101, and the length of the transverse supporting beam 1 can be adjusted by controlling the length of the telescopic steel pipe 102 extending out of the square steel pipe 101. Of course, when the telescopic steel pipe 102 extends out of the square steel pipe 101, the telescopic steel pipe and the square steel pipe need to be fixed to prevent sliding from occurring and affecting the stability of the platform. In the present invention, a plurality of pin holes are required to be formed in both the end of the square steel pipe 101 and the telescopic steel pipe 102, and the arrangement direction of the pin holes is parallel to the axial direction of the square steel pipe 101. After the telescopic steel pipe 102 and the square steel pipe 101 slide to proper positions, a pair of pin holes are formed between the telescopic steel pipe 102 and the square steel pipe 101, the axes of the pin holes are just overlapped, and then the pin holes are clamped through the pin shafts 103 to perform sliding limiting, so that a stretching adjusting component for adjusting the length of the transverse supporting beam 1 is formed. It is to be noted that the transverse support beam 1 is formed with one tension adjusting member at each end, and four tension adjusting members are provided throughout the platform.
Since the steel pipe has a large self-weight and is likely to generate rust and cause an excessive sliding friction force in long-term use, a sliding assistance facility may be provided in a preferred embodiment as shown in fig. 12. Specifically, because the cross-sectional dimension of the telescopic steel pipe 102 is smaller than the cross-sectional dimension of the square steel pipe 101, gaps are formed between the outer walls of the upper and lower sides of the telescopic steel pipe 102 and the inner walls of the upper and lower sides of the square steel pipe 101, and a plurality of rollers 105 facilitating the sliding of the telescopic steel pipe 102 are respectively arranged in the gaps. This allows the expansion/contraction steel pipe 102 to slide along the rollers 105, and thus to smoothly enter and exit the square steel pipe 101. In addition, at least one baffle 104 may be disposed inside the square steel tube 101 to limit the sliding depth of the telescopic steel tube 102 into the square steel tube 101. The setting position of the baffle 104 can ensure that the whole telescopic steel pipe 102 is just positioned in the square steel pipe 101 when the telescopic steel pipe 102 is in contact with the baffle 104. The tension adjusting member may be erected on the outer longitudinal steel beam B by a telescopic steel pipe 102 extending out of the square steel pipe 101, as shown in fig. 13. Of course, the drawing shows the case that both ends are stretched out for erection, and one end can be actually erected. After the telescopic steel pipe 102 extends out, the pin shaft 103 should be well clamped into the pin hole for sliding limitation, i.e. the state shown in fig. 14.
In order to ensure the stability of the whole structure, the axis direction of the third steel beam 303 is preferably parallel to the axis direction of the first steel beam 301 when the third steel beam is rotated to the horizontal state. In the four rotation adjusting members 3, the bottom surfaces of the third steel beams 303 are in the same horizontal plane when the third steel beams are in the horizontal state; among the four tension adjusting members, the bottom surfaces of the telescopic steel pipes 102 are also on the same horizontal plane. Finally, the whole installation state is as shown in fig. 15 and 16, the working platform a can be stably erected on the external longitudinal steel beam B through four stretched stretching adjusting members, so that the problem in fig. 1 is solved, and the application range of the working platform a is expanded.
Based on the construction operation platform, the invention can further provide a construction operation method of the super high-rise steel structure, which comprises the following steps:
firstly, the construction operation platform is integrally hoisted to the upper part of an external cantilever steel beam at a position to be constructed, and if the self sizes of two transverse supporting beams 1 or two longitudinal supporting beams 2 in a bottom frame of the construction operation platform are matched with the span of the cantilever steel beam, the construction operation platform is directly and stably erected on the cantilever steel beam for construction operation.
If the self size of two transverse supporting beams 1 or two longitudinal supporting beams 2 in the bottom frame of the construction work platform is smaller than the span of the cantilever steel beam, four rotating adjusting members 3 or four stretching adjusting members are correspondingly adjusted, and it should be noted that whether the rotating adjusting members 3 or the stretching adjusting members are specifically used for erection or not, one or both of the rotating adjusting members and the stretching adjusting members should be used according to the actual situation. When the rotation adjusting member 3 needs to be adjusted, the second steel beam 302 and the third steel beam 303 are rotated out of the first steel beam 301, so that the third steel beam 303 is kept in a horizontal state, the shaft hole at the other end of the second steel beam 302 is coaxial with the shaft hole in the middle of the first steel beam 301, and the fixing pin 304 penetrates through the shaft hole, so that the other end of the second steel beam 302 is fixed with the first steel beam 301; when the tension adjusting member needs to be adjusted, the telescopic steel pipe 102 is pulled out from the inside of the square steel pipe 101, the pulling-out distance is larger than the distance between the end part of the square steel pipe 101 and the external cantilever steel beam, then the end part of the square steel pipe 101 and the pin hole in the telescopic steel pipe 102 are kept coaxial through fine adjustment, and the pin shaft 103 is clamped into the pin hole to fix the square steel pipe and the telescopic steel pipe. And after the bottom framework of the construction operation platform is lengthened, the stable frame is stably erected on the cantilever steel beam to perform construction operation.
And after the operation of the current construction position is finished, integrally hoisting the construction operation platform to the next construction position again to carry out platform erection and construction operation according to the same method.
The above-described embodiments are merely preferred embodiments of the present invention, which should not be construed as limiting the invention. Various changes and modifications may be made by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present invention. Therefore, the technical scheme obtained by adopting the mode of equivalent replacement or equivalent transformation is within the protection scope of the invention.
