Description

Technical Field

[0002] Most concrete walls use a double-sided formwork system, with tension bolts used to fix the formwork on both sides. However, in some special environments, such as underground space construction, the operating space between the foundation pit retaining structure and the basement side wall is narrow, and there is no working space or formwork space outside the structure. The traditional double-sided formwork process is difficult to meet the construction requirements, and a single-sided formwork construction method is required.

[0003] At present, the traditional formwork method is mainly to weld the tension screws by planting reinforcement in the enclosure structure, and set the inclined brace outside the single-side formwork to achieve single-side formwork, but this method has complicated construction procedures, low work efficiency, and cannot guarantee the construction quality. The existing tool-type single-side formwork system, movable single-side formwork device, adjustable single-side formwork system and other methods can only achieve a single formwork height adjustment or the formwork device can only move in one direction, which has great application limitations, resulting in low construction efficiency of concrete pouring.

Therefore, in the concrete When pouring soil, the lifting jack moves the steel formwork system and the supporting truss system to the first pouring section to pour concrete.

[0046] A construction method for single-side formwork of an adjustable assembled steel formwork truss comprises the following steps:

[0047] S1. Steel formwork system assembly: Determine the number of steel formwork sheets required according to the height of the cast-in-place wall and the length of the first casting section, and fix them with fixing bolts to assemble them into a large integral steel formwork supporting concrete;

[0048] S2. Support truss system assembly: Determine the number of right-angle ladder heightening sections and triangular standard sections according to the height and width of the on-site concrete pouring, and connect them with each other through fixing bolts, and connect adjacent trusses through steel pipes;

[0049] S3. Installation of the displacement travel system: Lay transverse I-beams in the formwork area, set up longitudinal channel steel tracks on the transverse I-beam tracks, and place the entire combined system on the channel steel tracks. Jacks connected to the trusses are installed on the first and last sets of longitudinal channel steel tracks, and a winch fixed to the trusses is installed on one side of the transverse I-beam track;

[0050] S4. First stage of concrete pouring: First, the steel formwork system is sprayed with oil through the oil spraying assembly to facilitate separation from the concrete. Then, the steel formwork system is pushed to the designated position by the jack to support the concrete. When the concrete reaches the demoulding hardness, the steel formwork system is moved away from the concrete by the contraction of the jack.

[0051] S5. Next stage of concrete pouring: spray oil on the steel formwork system again, and use the winch to pull the steel formwork system and truss to the next stage of concrete pouring to pour concrete, and repeat the operation until the concrete pouring is completed.

[0052] According to the height of the cast-in-place wall and the length of a single casting section, the number of required steel formworks 2, the number of triangular standard sections 6 of the support trusses and the number of multiple right-angle ladder heightening sections are determined. At this time, multiple groups of triangular standard sections 6 and right-angle ladder heightening sections are assembled into a large, complete right-angle triangular support system through steel pipes 12, and the triangular support system is fixed to the steel formwork 2. Then, a transverse I-beam track 14 is laid in the formwork area, and a longitudinal channel steel track 17 is set on the transverse I-beam track 14. Then, the combined steel formwork system 1 and the support truss system 5 are placed on the longitudinal channel steel track 17. Due to the action of the first directional wheel 15 and the second directional wheel 18, the support truss system 5 is easily moved horizontally and vertically, and the action of the jack 21 controls the longitudinal movement of the support truss system 5. The hoist 24 controls the horizontal lateral movement of the support truss system 5. Therefore, when pouring concrete, the lifting jack 21 moves the steel mold system 1 and the support truss system 5 to the first pouring section position to pour concrete. When the concrete reaches the demoulding strength, the jack 21 is retracted to make the steel mold system 1 and the support truss system 5 away from the poured concrete, and then the support truss system 5 and the steel mold system 1 are pulled by the hoist 24 to move horizontally (the second positioning hole 22 is used to position the longitudinal channel steel rail 17. After the hoist 24 is started to drive the longitudinal channel steel rail 17 to move to a suitable position, the positioning pin is inserted into the second positioning hole 22, thereby positioning the longitudinal channel steel rail 17 to prevent movement). In this process, the motor 46 and the pump body 3 are started. 4, so the operation of the motor 46 will drive the driving shaft 47 to rotate, thereby driving the reciprocating screw 42 to rotate, and due to the action of the limit rod 43, the sliding block 41 is driven to move, thereby driving the rack 39 to reciprocate, thereby driving the flat gear 38 to reciprocate, and then driving the rotating tube 36 to reciprocate, thereby driving the movable tube 28 slidably connected thereto to reciprocate, thereby driving the nozzle 29 to reciprocate, and when the driving shaft 47 rotates, the second bevel gear 54 will be driven to rotate, thereby driving the first bevel gear 53 to rotate, thereby driving the rotating shaft 52 to rotate, thereby driving the threaded rod 51 to rotate, thereby driving the threaded block 50 to move, thereby driving the connecting rod 49 to move, thereby driving the fixing ring 48 to move, thereby driving the movable tube 28 to move, thereby driving The nozzle 29 moves, and when the threaded block 50 moves to another set of rotating shafts 52, the threaded rod 51 is disengaged from the threaded rod 51, so it will not drive the threaded block 50 to move, so that the movable tube 28 and the nozzle 29 stop moving, and the nozzle 29 moves to the front side of the steel formwork 2, so that the oil mist is evenly sprayed on the steel formwork 2 (due to the setting of the spring 57, when the threaded rod 51 reverses, due to the elastic force of the spring 57, the threaded block 50 and the threaded rod 51 are tightly fitted, so that the threaded block 50 moves in the opposite direction, thereby driving the connecting rod 49 and the fixing ring 48 to move in the opposite direction, thereby driving the movable tube 28 and the nozzle 29 to move in the opposite direction and reset, so that the nozzle 29 is located on the rear side of the steel formwork 2, so it does not affect the pouring of concrete).

[0053] When the driving shaft 47 rotates, it will drive the driving wheel 64 to rotate, and then drive the belt 65 to rotate, and then drive the driven wheel 66 to rotate, and then drive the wind wheel 67 to rotate, and then the wind wheel 67 generates wind force through the rotation of the wind wheel 67, which will blow into the air duct 32, and then enter the connecting pipe 33, and thus enter the air outlet pipe 59, and due to the effect of wind force, the air outlet pipe 59 is extended, and the tension spring 61 is stretched, so that the air outlet pipe 59 is located at the front side of the steel template 2 and above the oil spray, so that the sprayed oil mist is discharged, so that the oil mist falls on the steel template 2. (After the motor 46 reverses and drives the threaded rod 51 to reverse, the wind wheel 67 will also reverse at this time, so that the air outlet pipe 59 loses the effect of wind force at this time, so the air outlet pipe 59 is reset by the effect of the tension spring 61, so as to avoid affecting the concrete pouring, and due to the setting of the through hole 60 at the end of the air outlet pipe 59, it is beneficial to increase the resistance of the air outlet pipe 59, so that the wind force blows the air outlet pipe 59 out).
