Description

Technical Field

[0001] The present invention relates to the technical field of protective platforms, and in particular to a temporary operating protective platform for cap beam shaping construction. Background Art

[0002] See also Figure 1 The cap beam 6 is used to support the suspended asphalt road. The cap beam 6 is formed by casting, that is, first supporting the temporary work platform through a support frame, or supporting the temporary work platform through a bracket fixed to the pier 7 by a clamp, and then building an outer mold on the temporary work platform, and then casting the reinforced concrete cap beam 6 in the outer mold. After the reinforced concrete cap beam 6 structure is stable, the outer mold and the work platform can be removed. It should be noted that the top of the pier 7 is fixed with embedded steel bars of the cap beam 6. When the concrete mixture is poured into the outer mold and waited for it to solidify, the cap beam 6 of the reinforced concrete structure is formed.

[0003] However, to facilitate the installation and disassembly of the work platform, a bracket is typically installed on top of pier 7, followed by an I-beam or Bailey frame, and then a wooden assembly work platform is constructed on the I-beam or Bailey frame. While this arrangement facilitates assembly and disassembly of the work platform, meeting the requirements for rapid construction and disassembly, and therefore a common and long-standing construction method, it lacks protective measures and poses a significant safety hazard to workers. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a temporary work protection platform for cap beam shaping construction, which can protect the construction safety of workers while meeting the requirements of rapid installation and rapid disassembly.

[0005] The purpose of the present invention is achieved by adopting the following technical solutions:

[0006] A temporary working protection platform for cap beam shaping construction, comprising:

[0007] The platform support includes two vertical guard plates and two load-bearing rods, wherein the two vertical guard plates are arranged at intervals in the horizontal direction, and the two load-bearing rods are respectively located at the bottom of the two ends of the platform support, and the load-bearing rods are respectively fixedly connected to one of the vertical guard plates, so that the two vertical guard plates and the two load-bearing rods jointly surround a rising avoidance through hole, and the rising avoidance through hole is used to accommodate the formed cap beam and enable the platform support to be away from the formed cap beam in the height direction when dismantled;

[0008] The supported base plate includes two supported branch base plates that are independent of each other and arranged in a mirror image. The two ends of the supported branch base plates are respectively provided with downwardly protruding limit blocks. The supported base plate is overlapped on the two load-bearing rods. The two limit blocks of the supported branch base plates are respectively in contact with the outer side wall of one of the load-bearing rods to prevent the supported branch base plate from moving horizontally relative to the load-bearing rods. The supported base plate has a rounded rectangular avoidance through hole therein, and the rounded rectangular avoidance through hole is used for the top of the bridge pier to pass through.

[0009] The leak-tightening base plate comprises two independent and mirror-image branch leak-tightening plates, each having a semicircular groove at its end, wherein the two semicircular grooves belonging to different branch leak-tightening plates are respectively arranged at opposite ends of the leak-tightening base plate and face opposite directions; the leak-tightening base plate is placed above the supported base plate and covers the middle portion of the rounded rectangular avoidance through-hole, and the semicircular groove of each branch leak-tightening plate and one end of the rounded rectangular avoidance through-hole form a circular hole structure for accommodating one of the bridge piers;

[0010] The supporting legs are detachably connected to the bottom of the platform bracket and support the platform bracket.

[0011] Furthermore, the vertical protective plate is provided with a plurality of viewing angle through holes, and the plurality of viewing angle through holes are evenly distributed.

[0012] Furthermore, the platform bracket also includes a plurality of protection rods, which are respectively arranged at both ends of the platform bracket, and the two ends of the protection rods are respectively fixedly connected to one of the vertical protection plates, and the protection rods are located above the load-bearing rods.

[0013] Furthermore, the platform bracket is an integrated molding structure.

[0014] Furthermore, the platform bracket is made of steel.

[0015] Furthermore, the support leg comprises a plurality of inclined support legs and a plurality of reinforcing cross bars; the plurality of inclined support legs are arranged at intervals from each other, and both ends of the reinforcing cross bars are respectively detachably fixedly connected to one of the inclined support legs.

[0016] Furthermore, the supported bottom plate is made of steel.

[0017] Furthermore, the leak-proof bottom plate is made of steel.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The two vertical protective plates are fixed together by the two load-bearing rods of the platform bracket, so that the platform bracket is made into a whole and can be used as a prefabricated part without the need for on-site construction and can be reused, thereby greatly saving the time of building the platform bracket and improving construction efficiency.

[0020] 2. The two protective plates on the platform support can protect workers, thus greatly reducing construction hazards. The bottom of the platform support has a rising avoidance hole, so that after construction is completed, the platform support of the overall structure connected to the outer periphery of the cap beam can be lifted out by lifting equipment to meet the purpose of recycling and reuse of the platform support.

[0021] 3. The supported base plate is designed to be two independent and mirror-image supported branch base plates, so that the supported base plates can not only support the workers but also be dismantled in sequence without interference from the two bridge piers; and, in order to prevent the supported base plate from loosening, the supported base plate is provided with a rounded rectangular avoidance hole, which is used for the top of the bridge pier to pass through, so as to prevent the supported base plate from moving horizontally through the outer wall of the bridge pier to ensure the walking safety of the workers; further, the limit blocks at both ends of the supported branch base plate are respectively in contact with the outer side walls of the load-bearing rod to prevent the supported branch base plate from moving horizontally relative to the load-bearing rod, so as to further improve the safety of the supported base plate.

[0022] 4. By designing the leak-proof base plate into two independent and mirror-image branch leak-proof plates, and the ends of the branch leak-proof plates have semicircular grooves, so that the semicircular grooves and one end of the rounded rectangular avoidance through hole form a circular hole structure for accommodating one of the bridge piers, so that the circular hole structure and the bridge piers are matched one by one, the leak-proof base plate can not only fill the holes, but also be constrained by the two bridge piers. Therefore, even if the overlapping method is adopted, it is sufficient to prevent the leak-proof base plate from falling off, so as to facilitate the later disassembly.

[0023] 5. In particular, since the leak-proof base plate is pressed on the supported base plate, the overlap method of the supported base plate does not require other reinforcement parts for secondary protection. When necessary, it is only necessary to hammer a number of bolts or screws into the leak-proof base plate (of course, it can also be replaced by clamps), so that the workload of relying on violent demolition in the later stage is relatively small.

It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0036] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element, or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element, or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] See also Figure 2-Figure 5 A preferred embodiment of the present invention is a temporary working protection platform for cap beam shaping construction, comprising: a platform bracket 1, a supported base plate 2, a leak-proof base plate 3 and a supporting foot frame 5.

[0039] See also Figure 2 and Figure 4 The platform support 1 includes two vertical guard plates 11 and two load-bearing rods 12. The two vertical guard plates 11 are arranged at intervals in the horizontal direction. The two load-bearing rods 12 are respectively located at the bottom of both ends of the platform support 1. The load-bearing rods 12 are respectively fixedly connected to one of the vertical guard plates 11 (for example, welded), so that the two vertical guard plates 11 and the two load-bearing rods 12 jointly surround the rising avoidance through hole 13 (see Figure 7 and Figure 8 ), for easier understanding, please also refer to Figure 1 、 Figure 2 and Figure 9 The rising avoidance through hole 13 is used to accommodate the formed cap beam 6 and enable the platform bracket 1 to be away from the formed cap beam 6 in the height direction when dismantling; the specific dismantling process is: after the platform bracket 1 is supported by the crane, the supporting leg 5 is first removed, and then the platform bracket 1 is lowered by one to two meters in height to reserve space for the supported base plate 2 and the leak-proof base plate 3 to be dismantled, leaving only the platform bracket 1 to be sleeved on the outside of the cap beam 6. Based on the fact that the rising avoidance through hole 13 is much larger than the outer contour of the cap beam 6, it can be taken out in the height direction for recycling and reuse.

[0040] See also Figure 4 The supported base plate 2 includes two supported branch base plates 21 that are independent of each other and mirror-imaged. The two ends of the supported branch base plates 21 are respectively provided with downwardly protruding limit blocks 22. The supported base plate 2 is overlapped on the two load-bearing rods 12. The two limit blocks 22 of the supported branch base plates 21 are respectively in contact with the outer wall of one of the load-bearing rods 12 to prevent the supported branch base plates 21 from moving horizontally relative to the load-bearing rods 12, so as to ensure the walking safety of workers. The supported base plate 2 has a rounded rectangular avoidance hole 23 inside, which is used for the top of the pier 7 to pass through (see Figure 10 ) so that the embedded steel bars of the cap beam 6 are placed on the supported base plate 2, so as to meet the requirement of the outer formwork being arranged around the embedded steel bars of the cap beam 6.

[0041] See also Figure 3 and Figure 4 The leak-proof base plate 3 includes two independent and mirror-image branch leak-proof plates 31. The ends of the branch leak-proof plates 31 have semicircular grooves 311. The two semicircular grooves 311 belonging to different branch leak-proof plates 31 are respectively arranged at opposite ends of the leak-proof base plate 3 and face opposite directions. The leak-proof base plate 3 is placed on top of the supported base plate 2 and covers the middle of the rounded rectangular avoidance hole 23 (to prevent workers from stepping on empty space). The semicircular grooves 311 of each branch leak-proof plate 31 and one end of the rounded rectangular avoidance hole 23 form a circular hole structure 4 for accommodating one of the bridge piers 7 (which can be simultaneously referenced). Figure 10 ). In this way, the two semicircular grooves 311 of the branch leak-proof plate 31 are respectively constrained by the outer wall of one of the bridge piers 7, so that horizontal movement will not occur. In other words, the branch leak-proof plate 31 has a better stability effect on the basis of blocking the leak.

[0042] See also Figure 2 , it is necessary that the support legs 5 are detachably connected to the bottom of the platform support 1 and support the platform support 1. Obviously, the support legs 5 are used to ensure that the platform support 1 can be suspended in the air for workers to step on and work on. The support legs 5 must be detachably connected to the platform support 1, for example, by a bolt assembly, so that the support legs 5 can be removed first before removing the platform support 1 to prevent the support legs 5 from increasing the difficulty of lifting and removing the platform support 1.

[0043] When installing, see Figure 7 and Figure 8 , lift the platform support 1 by crane and move it to the top of the bridge pier 7, then lower the platform support 1 so that the two bridge piers 7 are located in the rising avoidance hole 13, then, see Figure 5 and Figure 6 , the supported branch bottom plates 21 of the supported bottom plate 2 are placed on the platform bracket 1 independently and in order, and the supported branch bottom plates 21 are supported by the load-bearing rods 12. Then, see Figure 3 and Figure 4 , the two branch sealing plates 31 of the sealing base plate 3 are placed independently on the supported base plate 2 to cover the remaining leaks; finally, the supporting legs 5 commonly used in the prior art are detachably fixedly connected to the platform bracket 1. It should be noted here that in the prior art, the supporting legs 5 adopt a detachable structure to facilitate disassembly, transportation, and storage. In this application, the main purpose is to ensure that the supporting legs 5 do not hinder the lifting and removal of the platform bracket 1.

[0044] When building the outer formwork, workers only need to stand on the platform support 1 to build the outer formwork. Since the platform support 1 has a vertical protective plate 11, the safety of the workers can be guaranteed.

[0045] During disassembly (i.e. after the cap beam 6 is cast), the platform bracket 1 is first supported by starting the equipment, and then the supporting legs 5 are removed. Then the lifting equipment drags the platform bracket 1 down by one to two meters, so that the entire protective platform is away from the completed cap beam 6 to reserve space for the disassembly of the supported base plate 2 and the leak-proof base plate 3. That is, the workers can lift the supported base plate 2 and the leak-proof base plate 3 upward relative to the platform bracket 1 to separate them from the platform bracket 1 and then take them out. After that, the platform bracket 1 is left alone and sleeved on the outside of the cap beam 6. The platform bracket 1 is lifted up in the height direction by the lifting equipment so that it can be taken out from the top of the cap beam 6 and recycled for reuse.

[0046] Obviously, the two vertical protective plates 11 are fixedly connected together by the two load-bearing rods 12 of the platform bracket 1, so that the platform bracket 1 is made into a whole and can be used as a prefabricated part without having to be rebuilt on site, and can be reused, thereby greatly saving the time of building the platform bracket 1 and improving construction efficiency. In other words, after the platform bracket 1 is welded or cast for the first time, it does not need to be disassembled and can be directly hoisted and used thereafter. The two protective plates based on the platform bracket 1 can protect the workers, thereby greatly reducing construction hazards. The bottom of the platform bracket 1 has a rising avoidance through-hole 13, so that the platform bracket 1 with an integral structure that is sleeved on the periphery of the cap beam 6 after construction is completed can be lifted out by lifting equipment to meet the purpose of recycling and reusing the platform bracket 1. By designing the supported base plate 2 into two supported branch base plates 21 that are independent of each other and mirror-set, the supported base plate 2 can not only support the workers, but also be dismantled in sequence without interference from the two bridge piers 7; and, in order to prevent the supported base plate 2 from loosening, the supported base plate 2 has a rounded rectangular avoidance hole 23, which is used for the top of the bridge pier 7 to pass through, so as to prevent the supported base plate 2 from moving horizontally through the outer wall of the bridge pier 7 to ensure the walking safety of the workers; further, the limit blocks 22 at both ends of the supported branch base plate 21 are respectively in contact with the outer side walls of the load-bearing rod 12 to prevent the supported branch base plate 21 from moving horizontally relative to the load-bearing rod 12, so as to further improve the safety of the supported base plate 2. By designing the leak-proof base plate 3 into two independent and mirror-image branch leak-proof plates 31, and the ends of the branch leak-proof plates 31 have semicircular grooves 311, so that the semicircular grooves 311 and one end of the rounded rectangular avoidance hole 23 form a circular hole structure 4 for accommodating one of the bridge piers 7, so that the circular hole structure 4 and the bridge pier 7 are matched one-to-one, the leak-proof base plate 3 can not only fill the hole, but also make it subject to the two bridge piers 7. Therefore, even if an overlapping method is used, it is sufficient to prevent the leak-proof base plate 3 from falling off, so as to facilitate subsequent disassembly. In particular, since the leak-proof base plate 3 is pressed on the supported base plate 2, the overlapping method of the supported base plate 2 does not require other reinforcements for secondary protection. When necessary, it is only necessary to hammer a few bolts or screws into the leak-proof base plate 3 (of course, it can also be replaced by clamps), so that the workload of relying on violent dismantling in the later stage is small.

[0047] Preferably, the vertical protective plate 11 is provided with a plurality of viewing holes 111 , and the plurality of viewing holes 111 are evenly distributed. Such arrangement facilitates workers to observe external conditions through the viewing holes 111 .

[0048] Preferably, the platform support 1 also includes multiple guard bars 14, each located at each end of the platform support 1. Each end of the guard bar 14 is fixedly connected to one of the vertical guard plates 11, and the guard bars 14 are positioned above the load-bearing bars 12. This arrangement further protects worker safety. It should be noted that the space between two adjacent guard bars 14 allows workers to pass through, allowing them to climb into the platform support 1 using lifting equipment or temporary stairs.

[0049] Preferably, the platform support 1 is an integrated structure, that is, formed by casting. Best, the platform support 1 is made of steel.

[0050] Preferably, the support frame 5 includes a plurality of inclined support legs 51 and a plurality of reinforcing cross bars 52. The plurality of inclined support legs 51 are spaced apart from each other, and the ends of the reinforcing cross bars 52 are respectively detachably fixed to one of the inclined support legs 51. It is understood that the support frame 5 can adopt a commonly used structure in the prior art.

[0051] Preferably, the supported base plate 2 is made of steel material to provide it with sufficient rigidity and strength. Similarly, the leak-proof base plate 3 is made of steel material.

[0052] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
