Description

Technical Field

[0001] The invention relates to the technical field of template anti-expansion measurement, and in particular to a template anti-expansion testing device for high-pier bridge construction. Background Art

[0002] In actual bridge construction, the piers of the bridge are important supporting structures. During the construction of the piers, especially for high piers, hydraulic self-climbing formwork is currently mainly used for mold casting. Thanks to the advantages of efficient construction of self-climbing formwork, it is widely used. However, after long-term use and the impact of poured concrete, the formwork is prone to expansion, resulting in formwork deformation and even leakage, which directly affects the quality of pier forming. The current formwork anti-expansion test device for high pier construction of bridges mainly uses measuring instruments such as lead sinkers for measurement. The measurement is not comprehensive and is prone to omissions. It is not convenient to use fluid pressure to measure the degree of formwork deformation. At the same time, the outer formwork of the self-climbing formwork is always installed on the climbing frame. The inner and outer forms need to be separated during demoulding, which is not convenient for measuring the expansion of the inner and outer forms at the same time. The inner and outer forms need to be measured point by point separately. The measurement during actual casting construction is time-consuming and labor-intensive, and it is not convenient to adapt to the measurement of special-shaped or inclined formworks. 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, and there is a hidden danger of leakage after casting. Summary of the invention

The reinforcement ribs of the outer mold are inspected, and the pressing plate 104 can be tightened at this time to fit the template steel frame 101 for positioning. The number of template steel frames 101 and rubber water bags 201 of this structure is set. At the same time, this structure can be more convenient for fitting detection of special-shaped templates to ensure versatility.

[0025] In the disclosed embodiment, the template leak-proof measuring piece 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 on the bottom of the template steel frame 101 below by a row of bolts; a rubber strip 302 is fixedly installed on the inner side of the right-angle plate 301, and the rubber strip 302 is used to seal and fit 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 to expand and fit on the outer wall of the high pier; The water is stored in the pressure expansion rubber bag 303; the bottom of the right angle plate 301 is flush with the inner side of the self-climbing outer mold template; the closed control part 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 connected to the water pressure expansion rubber bag 303; the water supply piston cylinder 401 passes through the right angle plate 301; the piston 402 is slidably sleeved on the water supply piston cylinder 401; the water supply threaded rod 403 is rotatably installed at the bottom of the piston 402, and the water supply threaded rod 403 is threaded It is connected to the water supply piston cylinder 401; the piston 402 is used to supply water pressure to the water pressure expansion rubber bag 303; the water supply piston cylinder 401 is provided with a scale, and the water supply piston cylinder 401 is a transparent plastic structure; the closed control component 4 is adopted, and the template leak-proof measuring component 3 is cooperated with, which can be used to detect the fit between the bottom of the self-climbing formwork outer mold and the pier column surface after climbing one level, so as to avoid the gap being too large and not being discovered.

At this time, the water pressure controls the water pressure expansion rubber bag 303 to expand and fit the outer wall of the high pier. If the upward movement of the piston 402 exceeds the standard, it means that the bottom of the right angle plate 301 is not tightly fitted to the outer wall of the high pier at this time, and there is a risk of leakage.

[0026] In the embodiment of the present disclosure, the inner mold measuring part 5 includes: a measuring sliding shaft 501, an inner mold spring 5011, a connecting block 502 and an extrusion plate 503.

The inner mold fitting part 6 can cooperate with the inner mold measuring part 5 to automatically detect the expansion and deformation of the outer mold while automatically detecting the expansion and deformation of the middle part of the inner mold, ensuring that the anti-expansion detection of this structure is comprehensive and avoiding the expansion of the inner mold without being discovered. At the same time, the inner mold fitting part 6 can use magnetic force to automatically position and detect, and it does not affect the normal demolding of the outer mold. It can automatically adapt and has a reasonable structure. It can automatically separate from the inner mold when the outer mold is demolded, ensuring that this structure can be directly applied to the existing self-climbing mold, and the electromagnet 605 is used to magnetically attract the positioning magnet 604 for fixation. At this time, the positioning magnet 604 drives the touch rod 603 to stably fit on the inner side of the inner mold for detection.

[0027] In the embodiment of the present disclosure, the expansion parameter display element 7 includes: a deformation measuring tube 701, a floating block 702, an alarm control tube 703, an electric coil 704 and an alarm light 705. The deformation measuring tube 701 is fixedly mounted on the vertical hose 203; the floating block 702 is sleeved inside the deformation measuring tube 701; the alarm control tube 703 is sleeved in the middle of the floating block 702; two electric coils 704 are fixedly mounted on the inner side of the alarm control tube 703; two alarm lights 705 are fixedly mounted on the deformation measuring tube 701; and scale lines are provided on the outer side of the deformation measuring tube 701; The deformation measuring tube 701 is a transparent structure; the floating block 702 is used to indicate the deformation and expansion degree of the template; a circle of through holes for adding water is provided on the top of the deformation measuring tube 701; the prompt control part 8 includes: a prompt fixed shaft 801 and an alarm electrical connector 802, the prompt fixed shaft 801 is fixedly installed inside the deformation measuring tube 701; two alarm electrical connectors 802 are fixedly installed at the bottom of the prompt fixed shaft 801; the two alarm electrical connectors 802 are respectively aligned with the upper and lower electrical coils 704; the upper alarm electrical connector 802, the upper electrical coil 704 and the upper alarm electrical connector 802 are ...

This structure adopts the light prompt method, which is more direct. At the same time, the deformation measuring tube 701 can also intuitively understand the degree of deformation. This structure uses the liquid level prompt method in conjunction with the two power coils 704, whether the template is squeezed by the pressure of pouring concrete to expand and deform, or the outer mold is long Inward concave deformation caused by use and violent demoulding can be prompted, and detection work can be achieved in conjunction with the rubber water bag 201 to ensure that the wall thickness and surface flatness of the high pier casting meet the standards. This structure can more directly reflect the state of the formwork. Because the inner mold is mostly assembled in a multi-piece form, the inner side will fit the concrete pad 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 the support arm of the self-climbing mold and the outer mold, so the probability of concave occurrence is low. This structure can better ensure the accuracy of deformation detection of the outer mold.

[0028] The working principle of this embodiment is as follows: first, water is added through a circle of through holes on the top of the deformation measuring cylinder (701), and the through holes on the template connecting plate 1011 are passed through bolts to be installed on the self-climbing formwork outer formwork. The three rows of tightening pressing plates 104 are rotated to loosen, and the sliding adjustment column 102 is used to adjust the position of the rubber water bag 201 to ensure that the rubber water bag 201 is stably fitted between the reinforcing ribs of the self-climbing formwork outer formwork for testing. At this time, the pressing plate 104 can be tightened and fitted to the template steel frame 101 for positioning. Once the template expands, the template will deform, and the deformation position is uniform. The rubber water bag 201 will be squeezed, and the water inside the rubber water bag 201 will be squeezed out, and the water level in the deformation measuring tube 701 will be controlled to rise; after the outer mold is closed, the swing plate 602 falls naturally, and the electromagnet 605 is used to attract the positioning magnet 604 for fixation. At this time, the positioning magnet 604 drives the touch rod 603 to fit stably on the inner side of the inner mold. Once the inner mold expands, the touch rod 603 can be driven to move inward. At this time, the measuring slide shaft 501 will be pulled to compress the inner mold spring 5011, and the connecting block 502 will also be driven to squeeze the plate 50 3. Squeeze the rubber water bag 201. At this time, the liquid level in the rubber water bag 201 is squeezed and rises again, which can be displayed by the floating block 702. When the casting is completed and the mold needs to be demoulded, the existing self-climbing mold usually expands the outer mold first, and then controls the outer mold to tilt. Before that, the positioning magnet 604 can be controlled to be powered off, and the naturally drooping swing plate 602 does not affect the outer mold to perform the above operations. When the template expands outward, the liquid level in the deformation measuring cylinder 701 rises, and the corresponding floating block 702 floats up. At this time, the power coil 704 below moves up and contacts the bottom The alarm electrical connector 802 at the bottom will be powered on to alarm. If the outer mold is concave, the rubber water bag 201 will also elastically fit and expand to absorb water. The corresponding floating block 702 moves down, and the upper power coil 704 moves up to contact the upper alarm electrical connector 802. At this time, the upper alarm light 705 will be powered on to alarm. During the measurement process, the display stroke corresponding to the scale lines on the two measuring slide shafts 501 can be directly observed to obtain the deformation of the middle part of the inner mold, which is convenient for the staff to analyze the deformation degree of the inner and outer molds. After the self-climbing formwork outer formwork climbs one level, the inner side of the bottom of the outer formwork will fit on the surface of the pier column for a closed fit. At this time, the water supply threaded rod 403 is rotated manually 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 self-climbing formwork outer formwork template, as shown in the attached figure. Figure 8 , and observe the scale on the water supply piston cylinder 401. If the upward movement of the piston 402 exceeds the standard, it means that the bottom of the right-angle plate 301 is not tightly fitted to the outer wall of the high pier, resulting in a gap that can be squeezed and pushed in to fill water, and there is a risk of leakage. If the gap is small, 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.
