[0039] It should be noted that the features in the embodiments of the application can be combined with each other without conflict.

[0040] As described in the background, the pouring formwork used in the pouring construction of the counterweight retaining wall construction includes steel supports and formworks, and the steel supports and the formworks are connected by I-shaped steel welding support. The I-shaped steel welding cannot be disassembled after the construction is completed, so that the whole pouring formwork cannot be reused repeatedly. In addition, the I-shaped steel welding cannot detect the size of the support force applied to the formwork.

[0041] Therefore, the embodiment of the utility model provides a support structure and a pouring formwork for counterweight retaining wall construction, which can solve the above problems. Next, the pouring formwork for counterweight retaining wall construction is described in detail.

[0042] Reference Figure 1 The embodiment of the utility model provides a pouring formwork for counterweight retaining wall construction, which comprises a formwork 100, a frame 200 and a support structure 300. The support structure 300 is detachably arranged between the formwork 100 and the frame 200. A plurality of formworks 100 are assembled to form a pouring cavity. The frame 200 is arranged outside the formwork 100 and serves to support and position the formwork 100.

[0043] It should be understood that the frame 200 herein corresponds to the steel support in the background. However, since the support structure 300 is detachably connected to the formwork 100 and the frame 200, the support structure 300 does not need to be welded to the formwork 100 and the frame 200. Therefore, the frame 200 can be made of high molecular materials, wood products or other materials in addition to steel structure support, further expanding the application range of the support structure 300 in construction.

[0044] In practical application, the number of support structures 300 is multiple, which are arranged at different positions of the formwork 100 and the frame 200 to ensure reliability.

[0045] The support structure 300 is described in detail as follows.

[0046] Reference Figures 2 to 4 The support structure 300 comprises a mounting plate 310, a support plate 311 and a pressing member. The mounting plate 310 is detachably connected to the frame 200. The support plate 311 is in contact with the formwork 100. The pressing member is arranged between the mounting plate 310 and the support plate 311. The two ends of the pressing member are connected to the mounting plate 310 and the support plate 311, respectively. The mounting plate 310 of the support structure 300 is detachably connected to the frame. The support plate 311 is in contact with the formwork 100, so that the support structure 300 can be quickly disassembled after the construction is completed and can be reused repeatedly.

[0047] In the embodiment, the mounting plate 310 is a long strip-shaped flat plate, and a fixing plate is fixed on the upper and lower side walls of the long strip-shaped flat plate, and screw holes are formed in the fixing plate, and bolts are threadedly connected with the screw holes, and the mounting plate 310 is connected with the frame 200 through the bolts. In other embodiments, screw holes can also be formed directly on the mounting plate 310, and the mounting plate 310 is directly connected with the frame 200 through bolts; or the mounting plate 310 is connected with the frame 200 through buckling connection; or other detachable connection modes can also be used.

[0048] In the embodiment, the support plate 311 is also a flat plate, and one side surface is connected with the pressing member, and the other side surface is connected with the mold plate 100. In other embodiments, the support plate 311 can also have other shapes, such as arc-shaped, arched, etc., and the specific size and shape need to be set according to actual needs.

[0049] In order to increase the fitting degree between the support plate 311 and the mold plate 100, the side surface of the support plate 311 connected with the mold plate 100 is provided with a contact pad, the contact pad is connected with the mold plate 100, and the contact pad is made of elastic material, such as rubber, so that the contact pad can be self-adaptively fitted on the surface of the mold plate 100.

[0050] Further, grooves are formed on the surface of the contact pad, thereby increasing the friction between the contact pad and the mold plate 100. Of course, other patterns or friction-increasing structures can also be provided on the contact pad, and the contact pad and the support plate 311 are fixedly connected through high-strength adhesive.

[0051] The pressing member between the support plate 311 and the mounting plate 310 is used to pressurize and depressurize the support plate 311, and the form of the pressing member includes various forms, such as air pressure, hydraulic pressure or mechanical structure. When air pressure is used, a pneumatic cylinder is arranged between the support plate 311 and the mounting plate 310, and the two ends of the pneumatic cylinder are respectively connected with the support plate 311 and the mounting plate 310; similarly, when hydraulic pressure is used, a hydraulic cylinder is arranged between the support plate 311 and the mounting plate 310, and the two ends of the hydraulic cylinder are respectively connected with the support plate 311 and the mounting plate 310. In the embodiment, the mechanical structure is used for pressure.

[0052] Continuing to refer to Figure 3The pressing member is a screw rod 314 and a threaded sleeve 313. The threaded sleeve 313 is provided with an internal thread, and the screw rod 314 is provided with an external thread. The internal thread is matched with the external thread. One end of the screw rod 314 is inserted into the threaded sleeve 313 and is threadedly connected with the threaded sleeve 313. The other end of the screw rod 314 is connected with the support plate 311. The end outer wall of the threaded sleeve 313 is sleeved with a bearing. A through hole is formed in the mounting plate 310. The bearing is embedded in the through hole in the mounting plate 310, so that the threaded sleeve 313 is rotationally connected to the mounting plate 310. When the threaded sleeve 313 is rotated, the screw rod 314 is equivalent to the threaded sleeve 313 rotating and moving in the axial direction, so as to adjust the distance and the pressure between the support plate 311 and the template 100.

[0053] Further, the support plate 311 is provided with a hinge seat, and the end of the screw rod 314 is fixedly connected with a hinge joint. The hinge joint is hingedly connected with the hinge seat. The hingedly connected screw rod 314 and support plate 311 have at least the following advantages: the support plate 311 can rotate relative to the screw rod 314, so as to adapt to the template 100 with different inclination angles in multiple cycles, and the support plate 311 can also be adjusted at any time during the connection with the template 100. The hinged connection does not affect the force transmission. In other embodiments, the screw rod 314 can also be welded to the support plate 311.

[0054] The surface of the threaded sleeve 313 is fixedly provided with an operating block 3131. When the threaded sleeve 313 needs to be rotated, a tool can be used to rotate the threaded sleeve 313 in cooperation with the operating block 3131, so that the operation is more convenient. Since the operating block 3131 can cooperate with various tools, the shape and structure of the operating block 3131 are not limited. Of course, the threaded sleeve 313 can also be manually rotated. At this time, a resistance increasing sleeve 3132 is fixedly arranged outside the threaded sleeve 313. The resistance increasing sleeve 3132 increases the friction with the hand, so as to avoid slipping during rotation.

[0055] In the embodiment, the threaded sleeve 313 is fixedly provided with a connecting plate away from the support plate 311. The connecting plate is rotationally matched with the threaded sleeve 313. Specifically, the end outer wall of the threaded sleeve 313 is sleeved with a bearing, and the connecting plate is provided with an embedding hole. The bearing is embedded in the embedding hole, so that the threaded sleeve 313 is rotationally connected to the mounting plate 310.

[0056] A push rod 312 is hingedly connected to the surface of the connecting plate away from the threaded sleeve 313. The number of the push rod 312 is not less than two. In the embodiment, the push rod 312 is two, which are symmetrically arranged on the two sides of the connecting plate.

[0057] The installation plate 310 is provided with a sliding groove 3101 on one side close to the support plate 311, and the sliding groove 3101 extends left and right along the long side of the installation plate 310. The end of the push rod 312 away from the connecting plate is hingedly connected with a sliding block 3121, and the sliding block 3121 is slidingly arranged in the sliding groove 3101 and can only slide in the sliding groove 3101 and cannot be displaced in other directions. When the support plate 311 is in complete contact with the template 100, the threaded sleeve 313 is continuously rotated, the push rod 312 pushes the sliding block 3121 to slide in the sliding groove 3101, the push rod 312 moves due to the hinged connection among the push rod 312, the connecting plate and the sliding block 3121, and the cooperation between the sliding block 3121 and the sliding groove 3101 ensures that the push rod 312 is adjusted along the predetermined route and the stability of the support is ensured.

[0058] With reference to the foregoing Figure 4 , the support structure 300 further comprises a support force detection assembly for detecting the force applied by the lead screw 314 to the support plate 311.

[0059] In this embodiment, the support force detection assembly comprises an observation cylinder 315, an elastic member 3151, an adjusting piston 3152, a piston rod 3153, an air pipe 3154, an air pressure gauge 3155 and a cross link 3156.

[0060] Specifically, the observation cylinder 315 is a hollow cylindrical cylinder with one end closed, and the elastic member 3151, the piston rod 3153 and the adjusting piston 3152 are arranged in the observation cylinder 315. The elastic member 3151 is a spring close to the closed end of the observation cylinder 315, the piston rod 3153 is located at the other end of the observation cylinder 315, the piston head of the piston rod 3153 is in sliding cooperation with the observation cylinder 315, the rod portion of the piston rod 3153 extends out of the end of the observation cylinder 315, and the rod portion of the piston rod 3153 extending out of the end of the observation cylinder 315 is fixedly connected with the sliding block 3121; the adjusting piston 3152 is located between the elastic member 3151 and the piston rod 3153. When the sliding block 3121 moves, the piston rod 3153 moves, thereby pressing the air in the observation cylinder 315, and the air after being pressurized pushes the adjusting piston 3152 to move to the side of the spring, thereby compressing the spring.

[0061] The air pipe 3154 is in communication with the interiors of the two observation cylinders 315, the air pressure gauge 3155 is arranged on the air pipe 3154, and the air pressure in the observation cylinder 315 is detected by the air pressure gauge 3155. When it is necessary to adjust the pressure of the support plate 311, the value detected by the air pressure gauge 3155 can be used as a reference. The pressure value of the support plate 311 adjusted by the air pressure value can be obtained by simulation, experiment or theoretical calculation, and will not be specifically described in detail in this embodiment.

[0062] Two cross connecting rods 3156 are fixed on the inner wall of the observation cylinder 315, the cross connecting rods 3156 do not affect the air flow on both sides, the limit moving distance of the adjusting piston 3152 and the piston rod 3153 can be limited through the cross connecting rods 3156, and excessive movement is avoided; meanwhile, the connecting position of the air pipe 3154 and the observation cylinder 315 is between the two cross connecting rods 3156, the observation cylinder 315 and the air pipe 3154 can be ensured to be in a connected state at all times, the air pressure gauge 3155 connected to the air pipe 3154 can detect the air pressure change in the observation cylinder 315 in real time, and then the pressure on the supporting plate 311 is adjusted.

[0063] It should be noted that the air pressure gauge 3155, the template 100 and the frame 200 in the embodiment can be selected from existing products, and the specific structure and working principle are not described in detail.

[0064] The working principle of the supporting structure 300 in the embodiment of the utility model:

[0065] After the template 100 and the frame 200 are installed in the early stage, a plurality of supporting structures 300 are installed. First, the mounting plate 310 is installed on the corresponding position of the frame 200 by using the bolt, the threaded sleeve 313 is rotated, the supporting is driven by the lead screw 314 to be close to the template 100, until the fitting is completed, the articulated connection of the lead screw 314 and the supporting plate 311 can make the supporting plate 311 adapt to the inclination of the surface of the template 100, the threaded sleeve 313 is continuously rotated, the sliding block 3121 is pushed to slide in the sliding groove 3101 by the push rod 312, the piston rod 3153 is moved by the moving sliding block 3121, the air in the observation cylinder 315 is extruded by the piston rod 3153, then the adjusting piston 3152 is extruded to move, the spring is compressed, the air pressure in the observation cylinder 315 is increased, the air pressure in the observation cylinder 315 can be measured through the air pressure gauge 3155 on the air pipe 3154, so that the adjustment of the supporting force is realized.
