Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a construction platform for post-pouring strips. Background Technology

[0002] In the construction of large-scale public buildings (such as airport terminals and large stadiums), post-cast strips crisscross, dividing the construction plan into multiple blocks. These post-cast strip areas are typically narrow (often 0.8-4 meters wide), and because they are temporary structural openings with dense formwork supports on both sides, space is extremely limited, making material transportation difficult. The traditional approach is to connect an unloading platform to the top of the post-cast strip for transport vehicles to pass through. However, for such complex conditions, traditional unloading platforms are simply unsuitable for installation and use in these areas due to their fixed dimensions, the need for on-site welding, their heavy weight, and the inability to effectively monitor loads. This results in extremely low material turnover efficiency, significant safety risks for personnel passage, and severe constraints on the construction schedule. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a construction platform for post-pouring strips, which can realize the rapid installation of the construction platform and at the same time detect the load in real time to avoid damage to the structure.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is a construction platform for post-pouring strips, comprising: A steel platform is installed along the length of the post-cast strip, and the steel platform spans the post-cast strip and is supported at both ends on the existing base plate. A load sensor, connected inside the steel platform, is used to monitor the load on the steel platform in real time. A displacement sensor is connected to the mid-span of the steel platform to monitor the deflection deformation in the mid-span of the steel platform in real time. An alarm is connected to the steel platform and to the load sensor and the displacement sensor. The alarm has a pre-stored maximum load and maximum deflection. The alarm will sound when the load detected by the load sensor is greater than the maximum load, or when the deflection detected by the displacement sensor is greater than the maximum deflection.

[0005] A further improvement of the construction platform for post-pouring strips in this invention is that the construction platform also includes multiple railings, and multiple sleeves are connected at intervals around the outer periphery of the steel platform for the multiple railings to be inserted one-to-one, and protective bars are detachably connected between adjacent railings.

[0006] A further improvement of the construction platform for post-pouring strips in this invention is that each of the railings is connected to the corresponding sleeve by a pin, and both the railing and the sleeve are provided with insertion holes for the pin to be inserted.

[0007] A further improvement of the present invention for the construction platform of the post-pouring strip is that a display is connected to the railing, and the display is connected to the load sensor for displaying the load on the steel platform in real time.

[0008] A further improvement of the construction platform for post-pouring strips in this invention is that the steel platform includes multiple steel platform units, which are arranged in a row end to end along the length of the post-pouring strip, and adjacent steel platform units are detachably connected.

[0009] A further improvement of the construction platform for post-cast strips in this invention is that each steel platform unit includes an upper steel plate, a lower steel plate, and multiple I-beams, wherein: the upper steel plate and the lower steel plate are spaced apart vertically; the multiple I-beams are spaced apart along the length direction of the post-cast strip and connected between the upper steel plate and the lower steel plate; each I-beam is perpendicular to the length direction of the post-cast strip and spans the post-cast strip; and the load sensor is located between the upper steel plate and the lower steel plate.

[0010] A further improvement of the construction platform for post-pouring strips in this invention is that each steel platform unit further includes two channel steels, both of which are parallel to the I-beams and located on opposite sides of the I-beams respectively. The two flanges of each channel steel are respectively connected to the upper steel plate and the lower steel plate. The web of each channel steel is flush with the corresponding end face of the upper steel plate and the lower steel plate. The webs of the channel steels of adjacent steel platform units abut against each other and are connected by bolts.

[0011] A further improvement of the construction platform for post-pouring strips in this invention is that the construction platform also includes two ramps, which are detachably connected to both ends of the steel platform for vehicles to go up and down the steel platform, and each ramp is arranged along the length of the post-pouring strip.

[0012] A further improvement of the present invention for the construction platform of the post-pouring strip is that the steel platform is connected to the existing base plate by anchor bolts.

[0013] Compared with the prior art, the advantages of the present invention are: 1. By setting up load sensors, displacement sensors and the alarm in combination, the support load of the steel platform can be detected in real time, avoiding excessive load from damaging the structure.

[0014] 2. By setting the steel platform into multiple steel platform units, the quantity can be adjusted according to the actual size of the post-pouring strip on site, meeting the needs of various specifications of post-pouring strips and improving practicality. Attached Figure Description

[0022] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0023] The construction platform for post-pouring strips of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Please see Figures 1-5 As shown, the construction platform for the post-pouring strip includes: A steel platform 1 is installed along the length of the post-cast strip. The steel platform 1 spans the post-cast strip and is supported on the existing base plate 2 at both ends. Load sensor 5 is connected inside the steel platform 1 and is used to monitor the load on the steel platform 1 in real time. Displacement sensor 8 is connected in the middle of the span of the steel platform 1 to monitor the deflection deformation in the middle of the span of the steel platform 1 in real time. An alarm 6 is connected to the steel platform 1 and to the load sensor 5 and the displacement sensor 8. The alarm 6 has a pre-stored maximum load and maximum deflection. When the load detected by the load sensor 5 is greater than the maximum load, or the deflection detected by the displacement sensor 8 is greater than the maximum deflection, the alarm 6 will sound an alarm.

[0025] By using load sensor 5, displacement sensor 8, and alarm 6 in conjunction, the support load and deformation of the steel platform 1 can be detected in real time, preventing excessive load from damaging the structure. Preferably, the construction platform also includes multiple railings 3, and multiple sleeves 11 are connected at intervals around the outer periphery of the steel platform 1 for the multiple railings 3 to be inserted one-to-one, and protective bars 4 are detachably connected between adjacent railings 3.

[0026] By connecting the railing 3 to the outer periphery of the steel platform 1, construction safety is improved and falls are prevented.

[0027] Preferably, each railing 3 is connected to the corresponding sleeve 11 by a pin, and both the railing 3 and the sleeve 11 are provided with a insertion hole for inserting the pin.

[0028] By detachably connecting the railing 3 to the sleeve 11, installation and turnover are facilitated, thus improving construction efficiency.

[0029] Preferably, a display 7 is connected to the railing 3, and the display 7 is connected to the load sensor 5 to display the load on the steel platform 1 in real time.

[0030] Specifically, the display 7 also shows the maximum quantity of various materials represented by the maximum load of the steel platform 1.

[0031] By setting the display 7 to convert the abstract maximum load value into the safe transport quantity of specific materials, the cognitive threshold of transportation workers is directly eliminated, and the intention to overload is eliminated from the source. This is an innovation at the level of "human defense".

[0032] Preferably, the steel platform 1 includes multiple steel platform units, which are arranged in a row along the length of the post-cast strip, and adjacent steel platform units are detachably connected.

[0033] Modular construction is achieved by splicing multiple steel platform units end to end in a row to completely cover the post-pouring strip, making it suitable for post-pouring strips of various specifications.

[0034] Preferably, each steel platform unit includes an upper steel plate 101, a lower steel plate 102, and multiple I-beams 103, wherein: the upper steel plate 101 and the lower steel plate 102 are arranged vertically at intervals, the multiple I-beams 103 are arranged at intervals along the length direction of the post-cast strip and connected between the upper steel plate 101 and the lower steel plate 102, each I-beam 103 is arranged perpendicular to the length direction of the post-cast strip and spans the post-cast strip, and the load sensor 5 is located between the upper steel plate 101 and the lower steel plate 102.

[0035] By using multiple I-beams 103, the rigidity of the steel platform unit is increased, preventing bending deformation.

[0036] Specifically, the load sensor 5 is located at the end of the steel platform 1, and its upper and lower ends are respectively attached to the relative inner sides of the upper steel plate 101 and the lower steel plate 102.

[0037] By setting the load sensor 5 at the end of the steel platform 1, when the steel platform 1 receives a load, the upper steel plate 101 will transfer the load to the load sensor 5, the load sensor 5 will then transfer the load to the lower steel plate 102, and the lower steel plate 102 will transfer the load to the existing base plate 2, ensuring that the load sensor 5 is fully stressed so as to obtain accurate load in real time.

[0038] Preferably, each steel platform unit further includes two channel steels, both of which are parallel to the I-beams 103 and located on opposite sides of the I-beams 103 respectively. The two flanges of each channel steel are respectively connected to the upper steel plate 101 and the lower steel plate 102. The web of each channel steel is flush with the corresponding end face of the upper steel plate 101 and the lower steel plate 102. The webs of the channel steels of adjacent steel platform units abut against each other and are connected by bolts 10.

[0039] Multiple steel platform units are connected into a whole by bolt 10, which is suitable for post-pouring strips of various specifications. In addition, the simple mechanical connection facilitates installation, disassembly and turnover, and improves construction efficiency.

[0040] Preferably, the construction platform also includes two ramps 9, which are detachably connected to both ends of the steel platform 1, for vehicles to go up and down the steel platform 1, and each ramp 9 is set along the length of the post-cast strip.

[0041] Since the steel platform 1 itself has a certain thickness, it is difficult for transport vehicles to get on and off the steel platform 1. Therefore, the ramp slab 9 is connected to both ends of the steel platform 1 to form two ramps at both ends of the steel platform 1, so as to facilitate vehicles to get on and off the steel platform 1.

[0042] Preferably, the steel platform 1 is connected to the existing base plate 2 by anchor bolts.

[0043] Specifically, the existing base plate 2 has a pre-installed anchor bolt, and the steel platform 1 has a through hole for the anchor bolt to pass through and connect.

[0044] By installing anchor bolts, the steel platform 1 is connected to the existing base plate 2 to prevent the steel platform 1 from moving in the opposite horizontal direction.

[0045] like Figure 5 As shown: The steel platform 1 is hoisted to the designed position by a tower crane, providing a method for hoisting a steel platform: Step 1: Use a tower crane to vertically hoist the steel platform 1 to directly above the post-cast strip, and connect a traction rope to the top and bottom of the steel platform 1 respectively; Step 2: Two construction workers stand on the existing base slab 2 on both sides of the post-cast strip and hold two of the traction ropes respectively; Step 3: As the steel platform 1 is lowered, the construction workers on both sides adapt by pulling on the two traction ropes, causing the steel platform 1 to flip until it is supported in the designed position.
