Description

Technical Field

[0001] The present invention relates to the technical field of formwork anti-expansion measurement, and particularly to a formwork anti-expansion test device for bridge high pier construction. Background Art

[0002] In actual bridge construction work, the pier columns of bridges are important supporting structures. During pier column construction, especially for high pier construction, currently, hydraulic self-climbing formwork is mainly used for formwork closing and pouring. Benefiting from the advantages such as high construction efficiency of the self-climbing formwork, it is widely used. However, after long-term use of the formwork and being impacted by the poured concrete, it is prone to formwork expansion, resulting in formwork deformation and even leakage, directly affecting the forming quality of the pier column. Currently, the formwork anti-expansion test devices for bridge high pier construction mainly use measuring instruments such as plumb bobs for measurement. The measurement comprehensiveness is not good, it is easy to miss, it is not convenient to measure the formwork deformation degree using fluid pressure. At the same time, the outer formwork of the self-climbing formwork is always installed on the climbing frame. When demolding, the inner and outer formworks need to be separated, which is not convenient to measure the expansion of the inner and outer formworks simultaneously. The inner and outer formworks need to be measured point by point respectively. The measurement during actual pouring construction is time-consuming and laborious, not convenient to adapt to the measurement work of special-shaped or inclined formworks, and the versatility is poor. At the same time, it is not convenient to measure the fitting gap error between the outer formwork of the self-climbing formwork and the pier column, and there is a hidden danger of slurry leakage after pouring.

A chute is provided on the formwork steel frame 101; a row of adjusting columns 102 are slidably installed in the chute on the formwork steel frame 101, and threaded holes are respectively provided on the row of adjusting columns 102; a lining plate 103 is respectively and fixedly installed on the row of adjusting columns 102.

[0039] In the embodiments of the present disclosure, the measurement support member 1 further includes: a template connecting plate 1011 and a tightening pressing disc 104. Two template connecting plates 1011 are fixedly installed on the template steel frame 101; two through holes are respectively provided on the two template connecting plates 1011; the through holes on the template connecting plate 1011 are used to pass through bolts to install the template connecting plate 1011 on the external formwork of the self-climbing formwork; a tightening pressing disc 104 is threadedly connected to the adjusting column 102, and the inner side of the tightening pressing disc 104 presses and fits against the side surface of the template steel frame 101; the fluid measurement member 2 includes: a rubber water bag 201, a horizontal hose 202 and a vertical hose 203.

By using the fluid measurement member 2 in cooperation with the measurement support member 1, it can be better applied to the anti-bulging detection of the self-climbing formwork. The three rows of rubber water bags 201 adopted can independently adjust their positions to ensure that the rubber water bags 201 are stably attached between the stiffeners of the external formwork of the self-climbing formwork for detection. This structure uses the rubber water bag 201 to test the deformation and expansion of the formwork by means of water pressure, and the detection is more comprehensive, which can prevent omissions. At the same time, the method of using fluid water for detection is direct in display, can be reused, and has a lower cost. It can be measured in real time during the pouring process, and problems can be dealt with in time. Slide the adjusting column 102 to adjust the position of the rubber water bag 201 to ensure that the rubber water bag 201 is stably attached between the stiffeners of the external formwork of the self-climbing formwork for detection. At this time, the tightening pressing disc 104 can be tightened to fit against the template steel frame 101 for positioning. The quantity setting of the template steel frame 101 and its rubber water bag 201 in this structure, and at the same time, this structure can be more convenient for fitting detection of special-shaped formworks, ensuring versatility. The shape of the template steel frame 101 and the size of the rubber water bag 201 can be determined according to the template style. Comprehensive fitting detection can be carried out for some skewed or arc-shaped formworks. For the external formwork that is prone to bulging, the anti-bulging detection can be ensured to be comprehensive. The reading of the method using liquid detection is intuitive, and the deformation degree can be intuitively understood.

[0040] In the embodiments of the present disclosure, the template leakage prevention measuring member 3 includes: a right-angle plate 301, a rubber strip 302, and a water-pressure expansion rubber bag 303. The right-angle plate 301 is fixedly installed at the bottom of the lower template steel frame 101 by a row of bolts; a rubber strip 302 is fixedly installed inside the right-angle plate 301, and the rubber strip 302 is used for sealing and fitting on the bottom of the template; a water-pressure expansion rubber bag 303 is fixedly installed on the right-angle plate 301, and the water-pressure expansion rubber bag 303 is used for expanding and fitting on the outer wall of the high pier; water is stored inside the water-pressure expansion rubber bag 303; the bottom of the right-angle plate 301 is flush with the inner side of the external formwork of the self-climbing formwork; the closing control member 4 includes: a water supply piston cylinder 401, a piston 402, and a water supply threaded rod 403. The water supply piston cylinder 401 is pipe-connected to the water-pressure expansion rubber bag 303; the water supply piston cylinder 401 passes through the right-angle plate 301; a piston 402 is slidably sleeved on the water supply piston cylinder 401; a water supply threaded rod 403 is rotatably installed at the bottom of the piston 402, and the water supply threaded rod 403 is threadedly connected to the water supply piston cylinder 401; the piston 402 is used for supplying water pressure into the water-pressure expansion rubber bag 303; a scale is provided on the water supply piston cylinder 401, and the water supply piston cylinder 401 is made of transparent plastic; by using the closing control member 4 in cooperation with the template leakage prevention measuring member 3, it can be used to detect the fitting degree between the bottom of the external formwork of the self-climbing formwork and the surface of the pier column after climbing one level, avoiding the situation where a too large gap is not detected. At the same time, this structure is more direct through the method of water pressure filling detection and will not cause omissions, which can ensure the comprehensiveness of the detection. The use of the rubber strip 302 and the water-pressure expansion rubber bag 303 can also play a sealing role, improving the sealing performance of the external formwork after formwork closure, improving the quality of the pouring construction, preventing slurry leakage and affecting the subsequent use of the self-climbing formwork. Rotating the water supply threaded rod 403 drives the piston 402 to move upward. At this time, the water pressure controls the water-pressure expansion rubber bag 303 to expand and fit on the outer wall of the high pier. If the upward movement amount of the piston 402 exceeds the standard, it means that the bottom of the right-angle plate 301 is not closely attached to the outer wall of the high pier, and there is a hidden danger of leakage.

[0041] In the embodiments of the present disclosure, the inner mold measuring member 5 includes a measuring sliding shaft 501, an inner mold spring 5011, a connecting block 502, and a pressing plate 503. Two measuring sliding shafts 501 are slidably mounted on the top template steel frame 101, and a connecting block 502 is fixedly mounted on the two measuring sliding shafts 501; a pressing plate 503 is fixedly mounted at the bottom of the connecting block 502; the pressing plate 503 presses and fits against the rubber water bag 201; inner mold springs 5011 are respectively sleeved on the two measuring sliding shafts 501; the ends of the two inner mold springs 5011 are fixedly mounted on the measuring sliding shafts 501, and the other ends of the two inner mold springs 5011 are fixedly mounted on the side of the top template steel frame 101; scale lines are respectively provided on the two measuring sliding shafts 501; the inner mold fitting member 6 includes a rotating connection frame 601, a swinging plate 602, and a touch rod 603. The rotating connection frame 601 is fixedly mounted on the side of the connecting block 502; a swinging plate 602 is rotatably mounted on the rotating connection frame 601; a touch rod 603 is fixedly mounted at the bottom of the swinging plate 602, and the touch rod 603 is used to fit against the inner mold of the self-climbing formwork; the inner mold fitting member 6 further includes a positioning magnet 604 and an electromagnet 605. The positioning magnet 604 is fixedly mounted on the top of the swinging plate 602; an electromagnet 605 is fixedly mounted on the rotating connection frame 601, and the electromagnet 605 is used to magnetically attract the positioning magnet 604. By using the inner mold fitting member 6, it is possible to cooperate with the inner mold measuring member 5 to automatically detect the easily expandable and deformable part in the middle of the inner mold while detecting the expansion and deformation of the outer mold, ensuring comprehensive anti-expansion detection of the structure and avoiding the undetected expansion of the inner mold. At the same time, by using the inner mold fitting member 6, automatic positioning detection can be carried out by using magnetic force, and it does not affect the normal demolding work of the outer mold. It can be automatically adapted, and the structure is reasonable. It can be automatically separated from the inner mold when the outer mold is demolded, ensuring that the structure can be directly applied to the existing self-climbing formwork. The positioning magnet 604 is fixed by magnetically attracting the positioning magnet 604 by the electromagnet 605. At this time, the positioning magnet 604 drives the touch rod 603 to stably fit against the inner side of the inner mold for detection.

[0042] In the embodiments of the present disclosure, the expansion parameter display member 7 includes a deformation measurement cylinder 701, a floating block 702, an alarm control cylinder 703, an energizing coil 704, and an alarm light 705. The deformation measurement cylinder 701 is fixedly installed on the vertical hose 203; a floating block 702 is sleeved inside the deformation measurement cylinder 701; an alarm control cylinder 703 is sleeved in the middle of the floating block 702; two energizing coils 704 are fixedly installed inside the alarm control cylinder 703; two alarm lights 705 are fixedly installed on the deformation measurement cylinder 701; scale lines are provided on the outer side of the deformation measurement cylinder 701; the deformation measurement cylinder 701 is of a transparent structure; the floating block 702 is used to indicate the degree of expansion of the template deformation; a circle of through holes for adding water are provided at the top of the deformation measurement cylinder 701; the prompt control member 8 includes a prompt fixed shaft 801 and an alarm power connection head 802. The prompt fixed shaft 801 is fixedly installed inside the deformation measurement cylinder 701; two alarm power connection heads 802 are fixedly installed at the bottom of the prompt fixed shaft 801; the two alarm power connection heads 802 are respectively aligned with the upper and lower energizing coils 704; a power supply is connected in series between the upper alarm power connection head 802, the upper energizing coil 704, and the upper alarm light 705; a power supply is connected in series between the lower alarm power connection head 802, the lower energizing coil 704, and the lower alarm light 705. By using the prompt control member 8, it is convenient for the staff to more directly understand that the deformation exceeds the standard and stop operations such as pouring in time. This structure uses a lighting prompt method, which is more direct. At the same time, the deformation degree can be intuitively understood by using the deformation measurement cylinder 701. This structure uses the liquid level prompt method in cooperation with the two energizing coils 704. Whether the template expands and deforms due to the pressure extrusion of the poured concrete, or the inner mold is affected by long-term use of the outer mold and violent demolding and other factors and undergoes inward concave deformation, prompts can be made. In cooperation with the rubber water bag 201, the detection work can be realized to ensure that the wall thickness and surface flatness of the high pier after pouring are up to standard. This structure can more directly reflect the state of the template. Since the inner mold is mostly in the form of multi-piece assembly, the inner side will fit the concrete cushion blocks of the steel cage of the pier column. The steel cage has an inward limiting effect on the inner mold, and the inner mold does not have structures such as support arms of the self-climbing formwork outer mold, and the probability of its inward concavity is relatively low. This structure can better ensure the accuracy of the deformation detection of the outer mold.

[0043] Working principle of this embodiment: First, add water through the through holes around the top of the deformation measuring cylinder (701). Pass the through holes on the template connecting plate 1011 through bolts and install them on the external formwork of the self-climbing formwork. Rotate and loosen the three rows of tightening pressing plates 104, and slide the adjusting column 102 to adjust the position of the rubber water bag 201 to ensure that the rubber water bag 201 is stably attached between the stiffeners of the external formwork of the self-climbing formwork for detection. At this time, the pressing plate 104 can be tightened to fit and position with the formwork steel frame 101. Once the formwork expands, the formwork will deform, and the deformed positions will all squeeze the rubber water bag 201. At this time, the water inside the rubber water bag 201 will be squeezed out, controlling the water level in the deformation measuring cylinder 701 to rise; after the external formwork is closed, the swing plate 602 will naturally fall, and the positioning magnet 604 is fixed by using the electromagnet 605 for magnetic attraction. At this time, the positioning magnet 604 drives the touch rod 603 to stably fit on the inner side of the internal formwork. Once the internal formwork expands, it can drive the touch rod 603 to move inward. At this time, the measuring sliding shaft 501 will be pulled to compress the internal formwork spring 5011. At this time, the connecting block 502 will also be driven, and the rubber water bag 201 is squeezed through the pressing plate 503. At this time, the liquid level in the rubber water bag 201 is squeezed and rises again, and the floating block 702 can be used for display; when demoulding is required after pouring is completed, the existing self-climbing formwork usually expands the external formwork first, and then controls the external formwork to tilt. Before that, just control the positioning magnet 604 to cut off the power. The naturally drooping swing plate 602 does not affect the above operations of the external formwork; when the formwork bulges outward, the liquid level in the deformation measuring cylinder 701 rises at this time, and the corresponding floating block 702 floats upward. At this time, the lower power-on coil 704 moves upward and will contact the lower alarm power-on head 802. At this time, the lower alarm lamp 705 will be powered on for alarm. Correspondingly, if the external formwork is concave inward, the rubber water bag 201 will also elastically fit and absorb water. The corresponding floating block 702 moves downward, and the upper power-on coil 704 moves upward and will contact the upper alarm power-on head 802. At this time, the upper alarm lamp 705 will be powered on for alarm. During the measurement process, the display stroke corresponding to the scale lines on the two measuring sliding shafts 501 can be directly observed to know the deformation of the middle part of the internal formwork, which is convenient for the staff to analyze the deformation degree of the internal and external formworks;

[0044] After the external formwork of the self-climbing formwork climbs one level, the inner side of the bottom of the external formwork will fit and seal on the surface of the pier column. At this time, manually operate and rotate the water supply screw rod 403 to drive the piston 402 to move upward. At this time, the water pressure controls the water pressure expansion rubber bag 303 to expand and fit on the outer wall of the high pier. The bottom of the right-angle plate 301 is flush with the inner side of the external formwork template of the self-climbing formwork, as shown in the appendix Figure 8, while observing the scale on the water supply piston cylinder 401, if the upward movement amount of the piston 402 exceeds the standard, it indicates that the bottom of the right-angle plate 301 does not closely fit the outer wall of the high pier at this time, resulting in a gap that can be squeezed to push in and fill water, posing a leakage risk. If the gap amount is small and within a reasonable range, the expanded water pressure is used to expand the rubber bag 303 to fit the outer wall of the high pier, and the rubber strip 302 is used to fit the outer mold, which can enhance the sealing effect.
