Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a counterweight type template support structure for retaining wall construction. Background Art

[0002] Counterweight retaining walls utilize the downward pressure of the fill on a counterweight platform and the rearward shift of the wall's center of gravity to increase wall stability. The steep breast slope and slanted lower wall reduce wall height and minimize foundation excavation. Consequently, they are widely used in municipal, highway, and port and shipping projects. Due to their unique structural design, counterweight retaining walls are currently primarily constructed using segmented formwork and pouring for the upper and lower walls, with the lower wall poured first, followed by the upper wall.

[0003] After searching, the Chinese patent "Counterweight Retaining Wall One-time Casting Formwork" with the authorization announcement number "CN 216615952U" was found. It can realize one-time formwork support and one-time concrete pouring of cast-in-place counterweight retaining wall formwork, with safe and stable structure and strong operability, greatly improving construction efficiency.

[0004] Although the above application can achieve one-time pouring construction, the steel support and the panel are welded at both ends of the I-beam to achieve support for the panel. However, due to the inclined state of the panel, multiple I-beams need to be cut and welded with high requirements, which affects construction efficiency and is not convenient for recycling of the device.

[0005] Therefore, a counterweight retaining wall construction formwork support structure is proposed to solve the above problems. Utility Model Content

[0012] Preferably, two sliding grooves are provided on the other side of the mounting plate, one end of the push rod is hinged with a slider that slides in the sliding groove, one end of the piston rod is fixedly connected to the slider, which can limit the movement of the push rod, and at the same time, the slider can be used to drive the piston rod to operate automatically to ensure stable operation of the device.

[0013] Preferably, an air pipe is provided between the two observation tubes, and a pressure gauge is provided on the surface of the air pipe to ensure that the air pressure values inside the two observation tubes are consistent, thereby improving the stability of the supporting force. At the same time, the air pressure value inside the observation tube can be directly understood through the pressure gauge, which facilitates the adjustment operation of the device.

[0014] Preferably, a cross-link is fixedly connected to the inner wall of the observation tube, and the connection between the air pipe and the observation tube is located between the two cross-links.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] When implementing: Figure 1-4 As shown, a formwork support structure for counterweight retaining wall construction includes:

[0027] Template 100 and Frame 200 Frame 200 is installed on template 100;

[0028] Support mechanisms 300 , wherein a plurality of support mechanisms 300 are disposed between the template 100 and the frame 200 ;

[0029] The support mechanism 300 includes a mounting plate 310 fixedly connected to the frame 200 and an observation tube 315. Two push rods 312 are provided on the other side of the mounting plate 310. The other ends of the two push rods 312 are hinged to a connecting plate. The other side of the connecting plate is rotatably connected to a threaded sleeve 313. The other end of the threaded sleeve 313 is threadedly connected to a screw rod 314. The other end of the screw rod 314 is hinged to the support plate 311.

[0030] One end of the inner wall of the observation tube 315 is fixedly connected to a spring 3151 , and the other end of the spring 3151 is fixedly connected to an adjusting piston 3152 . A piston rod 3153 is provided in the observation tube 315 .

[0031] like Figure 2 、 Figure 3 and Figure 4 As shown, two slots 3101 are defined on the other side of the mounting plate 310. One end of the push rod 312 is hingedly connected to a slider 3121 that slides within the slots 3101. One end of the piston rod 3153 is fixedly connected to the slider 3121. After the support plate 311 is fully in contact with the template 100, adjustment continues. The push rod 312 pushes the slider 3121 to slide within the slots 3101. The moving slider 3121 pushes the piston rod 3153, which compresses the air pressure within the observation tube 315. Due to the hinged connection between the push rod 312, the connecting plate, and the slider 3121, the push rod 312 adapts to the deformation of the push rod 312. At the same time, the cooperation between the slider 3121 and the slots 3101 ensures that the push rod 312 is adjusted along the predetermined path. At the same time, the slider 3121 pushes the piston rod 3153 along the predetermined path, ensuring the stability of the device adjustment.

[0032] An air pipe 3154 is provided between the two observation tubes 315, and a barometer 3155 is provided on the surface of the air pipe 3154. When adjusting, the air pressure in the observation tube 315 increases. Under the effect of the connection of the air pipe 3154, the barometer 3155 can observe the air pressure value, thereby achieving the adjustment of the supporting force.

[0033] A cross link 3156 is fixedly connected to the inner wall of the observation tube 315. The connection between the air pipe 3154 and the observation tube 315 is located between the two cross links 3156. This limits the final position of the adjustment piston 3152 and piston rod 3153, preventing them from excessive movement during adjustment, ensuring normal operation of the device and maintaining connectivity between the observation tube 315 and the air pipe 3154.

[0034] like Figure 2 and Figure 3 As shown, a contact pad is provided on the other side of the support plate 311, and grooves are evenly distributed on the other side of the contact pad. The rubber contact pad can be adaptively fitted to increase the friction between the contact pad and the template 100. At the same time, the contact pad can be changed to a certain extent, and the fitting effect is better.

[0035] An operating block 3131 is fixedly connected to the middle portion of the surface of the threaded sleeve 313, and a resistance-enhancing sleeve 3132 is provided on the surface of the threaded sleeve 313. The operating block 3131 can be rotated using existing tools to rotate the threaded sleeve 313. Alternatively, the palm of the hand can be directly placed in contact with the resistance-enhancing sleeve 3132 to rotate the threaded sleeve 313. This increases friction between the palm of the hand and the threaded sleeve 313, preventing slipping during rotation, reducing the difficulty of rotating the threaded sleeve 313, and making operation easier.

[0036] The top and bottom ends of the mounting plate 310 are fixedly connected to a fixing plate, and the fixing plate and the frame 200 are fixedly connected by bolts. The bolts and the fixing plate can be used to connect the mounting plate 310 to the frame 200. This method can be disassembled later, which is convenient for the later recycling of the support mechanism 300.

[0037] When the cam 315 is in the unlock position, the support rod 311 is in the unlock position, and the support rod 311 is in the unlock position, and the support rod 311 is in the unlock position, and the support rod 311 is in the unlock position, and the support rod 311 is in the unlock position, and the support rod 311 is in the unlock position, and the support rod 311 is in the unlock position, and the support rod 311 is in the unlock position, and the support rod 311 is in the unlock position, and the support rod 311 is in the unlock position, and the support rod 311 is in the unlock position, and the support rod 311 is in the unlock position, and the support

[0038] It should be noted that the template 100, barometer 3155, etc. in the above description are all devices with relatively mature applications in existing technologies. The specific models can be selected according to actual needs. At the same time, the template can be the template in the comparison case or a conventional building template. It can be selected according to the existing situation. In this field, the template can be used once or multiple times, but the supporting mechanism can be recycled, which will not be elaborated here.

[0039] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
