Technical Field

[0001] The invention relates to the technical field of small box girders of ramp bridges, and in particular to a prefabricated template system and method for small box girders of ramp bridges. Background Art

[0002] The small box girder of ramp bridge is a small box girder structure used for the construction of ramp bridges. It is widely used in the field of highway traffic, especially in the construction of ramps on highways and urban expressways. The prefabricated formwork for the small box girder of ramp bridge is a mold used to make small box girders. It has good advantages in quality, production efficiency and cost control.

[0003] In the existing technology, although the existing prefabricated formwork for small box girders of ramp bridges can produce the required small box girders quickly and with high quality during actual use, it does not have the functions of monitoring and processing. When the prefabricated formwork is deformed due to excessive force during the concrete pouring process, the prefabricated formwork without monitoring and processing functions will not be able to send an alarm prompt to the staff in time, and at the same time, the concrete leaked from the prefabricated formwork will not be processed, and thus timely loss control cannot be achieved, which not only reduces the use effect of the prefabricated formwork for small box girders of ramp bridges, but also reduces the use efficiency of the prefabricated formwork for small box girders of ramp bridges.

At the same time, the concrete leaked from the gap between the long side plate 107 and the bottom plate 112 will directly enter the interior of the corresponding guide shell 207, and then be diverted to the interior of the space composed of the main shell 201, the auxiliary shell 202, the inclined plate 205, the base 111 and the two sealing strips 206 for storage, but the controller 215 will not start the delivery pump 212. When the data is greater than the strain threshold value set in advance by the controller 215, and the capacitance value data received by the controller 215 is greater than the capacitance value threshold value set in advance by the controller 215, it means that the prefabricated template cannot be used normally. At this time, the controller 215 will send an alarm prompt to the staff through the alarm to remind the staff to stop injecting concrete into the prefabricated template. At the same time, the controller 215 will directly start the delivery pump 212. The delivery pump 212 that is subsequently started will, with the cooperation of the connecting pipe 213 and the three-way pipe 211, pump out the concrete that has reached the space composed of the main shell 201, the auxiliary shell 202, the inclined plate 205, the base 111 and the two sealing strips 206, and deliver it to the inside of the discharge pipe 214, and then deliver it to the box or collection tank for collecting concrete, that is, reduce resource waste.

[0044] The effect and working principle of the whole mechanism are as follows: when it is necessary to make a small box girder of a ramp bridge, the auxiliary shell 202 is first moved by a professional tool, so that the moving auxiliary shell 202 drives the sealing strip 206 connected thereto, the two L-shaped plates 209 connected thereto, the connecting plate 203 connected thereto, the inclined plate 205 connected thereto and the three-way pipe 211 connected thereto to move synchronously, until the inner surface of the moving sealing strip 206 and the inner surface of the inclined plate 205 are in contact with the surface of the base 111, and then the main shell 201 is driven to move by a professional tool, so that the moving main shell 201 drives the sealing strip 206 connected thereto to move, until the inner surface of the moving sealing strip 206 is in contact with the surface of the base 111, and the two sealing strips 206 are in contact with the inner surface of the moving sealing strip 206. The two sides are in contact with each other, and then the main shell 201 and the auxiliary shell 202 are fixed together by the cooperation of the first bolt and the first nut, and the main shell 201 and the auxiliary shell 202 are respectively installed together with the two connecting blocks 204, and then the delivery pump 212 is installed on the connecting plate 203, and the controller 215 and the water drop sensor 208 are installed on the auxiliary shell 202, and then the feed end of the connecting pipe 213 connected to the feed end of the delivery pump 212 is installed together with the discharge end of the three-way pipe 211, and then the discharge end of the discharge pipe 214 connected to the discharge end of the delivery pump 212 is placed in a box or collection tank for collecting concrete, and finally the controller 215 is connected to the external power supply through the prepared power cord, and the controller is 215 is also connected to the prepared alarm, and after completing the connection operation, turn on the controller 215, set the strain threshold, capacitance threshold and basic usage procedures, and when everything is ready, first use the special lifting device and the two long support frames 105 to move the two long side panels 107 until the opposite sides of the two long side panels 107 are in contact with the front surface of the bottom plate 112 and the rear surface of the bottom plate 112, and then use the special lifting device and the two short support frames 102 to move the two short side panels 101 until the opposite sides of the two short side panels 101 are in contact with the two sides of the bottom plate 112 respectively, and the two sides of each long side panel 107 are in contact with the opposite sides of the two short side panels 101 respectively, and then use the prepared second bolts, multiple The bottom plate 112, the two short side plates 101 and the two long side plates 107 are fixed together by the cooperation of the short plate 113 and the second nut, and then the two top plates 108 are symmetrically installed between the two short side plates 101, and then the two cover plates 109 are respectively installed on the two top plates 108, and then the two long strain gauges 216 are respectively installed on the two long side plates 107. When the prefabricated formwork of the small box girder of the ramp bridge is assembled, the tied steel bar frame is directly placed inside the prefabricated formwork, and then a proper amount of concrete is injected into the inside of the prefabricated formwork, and at the same time, the water drop sensor 208 and the two long strain gauges 216 are turned on by the controller 215. At this time, the opened water drop sensor 208 and the two long strain gauges 216 will continuously detect,The strain data and two capacitance value data detected each time are transmitted to the controller 215, and then the controller 215 will compare the strain data and two capacitance value data received each time with the strain threshold value and capacitance value threshold value set in advance by the controller 215, respectively. When the strain data received by the controller 215 is less than the strain threshold value set in advance by the controller 215, and the capacitance value data received by the controller 215 is less than the capacitance value threshold value set in advance by the controller 215, it means that the prefabricated template is used normally, and the controller 215 will not start the delivery pump 212. When the strain data received by the controller 215 is less than the strain threshold value set in advance by the controller 215, When the strain threshold value set by the controller 215 is exceeded, and the capacitance value data received by the controller 215 is greater than the capacitance value threshold value set in advance by the controller 215, it indicates that the prefabricated template is used normally, and the controller 215 will not start the delivery pump 212. When the strain data received by the controller 215 is greater than the strain threshold value set in advance by the controller 215, and the capacitance value data received by the controller 215 is less than the capacitance value threshold value set in advance by the controller 215, it indicates that the prefabricated template cannot be used normally. At this time, the controller 215 will send an alarm prompt to the staff through the alarm to remind the staff to stop injecting concrete into the prefabricated template, and at the same time, the long side plate 107 and the bottom plate 108 are used to inject concrete into the prefabricated template. The concrete leaking out from the gaps between the plates 112 will directly enter the interior of the corresponding guide shell 207, and then be diverted to the space composed of the main shell 201, the auxiliary shell 202, the inclined plate 205, the base 111 and the two sealing strips 206 for storage, but the controller 215 will not start the delivery pump 212. When the strain data received by the controller 215 is greater than the strain threshold value set in advance by the controller 215, and the capacitance value data received by the controller 215 is greater than the capacitance value threshold value set in advance by the controller 215, it means that the prefabricated template cannot be used normally. At this time, the controller 215 will send an alarm prompt to the staff through the alarm. , reminding the staff to stop injecting concrete into the precast formwork. At the same time, the controller 215 will directly start the delivery pump 212. The delivery pump 212 that is subsequently started will, with the cooperation of the connecting pipe 213 and the three-way pipe 211, pump out the concrete that has reached the space composed of the main shell 201, the auxiliary shell 202, the inclined plate 205, the base 111 and the two sealing strips 206, and deliver it to the inside of the discharge pipe 214, and then to the box or collection tank for collecting concrete, that is, to reduce resource waste. When the concrete in the precast formwork in normal use has completed a period of static operation, the precast formwork can be directly removed from the formed small box beam. ,
