Description

Technical Field

[0001] The utility model relates to the technical field of construction, and more particularly to a device for detecting the bearing capacity of a reinforced concrete prefabricated beam. Background Art

[0002] In construction projects, testing the bearing capacity of reinforced concrete precast beams is a key step in ensuring project quality. Traditional precast beam bearing capacity testing devices usually place the precast beams on a simple supporting structure and then apply pressure through a loading device to test their bearing capacity.

[0003] However, this traditional detection device has a serious problem, namely, the inaccurate positioning of the precast beam during the detection process. Due to the lack of an effective positioning and adjustment mechanism, the placement of the precast beam on the supporting structure is often not precise enough, which results in the precast beam being subjected to uneven and unconcentrated stress points when bearing pressure. This uneven stress situation will have many negative impacts on the detection work. On the one hand, it will make the test data inaccurate because the stress situation of the precast beam does not conform to the theoretical assumptions and cannot truly reflect its actual bearing capacity, which may lead to misjudgment of the quality of the precast beam. For example, if the stress point is biased to one side, cracks or signs of damage may appear on that side prematurely, while the bearing capacity of the other side is not fully tested, thus affecting the assessment of the bearing capacity of the entire precast beam. On the other hand, since the test results may fluctuate greatly due to the different placement of the precast beam, in order to obtain relatively reliable data, it is often necessary to repeatedly adjust the position of the precast beam and re-test, which greatly increases the workload and time cost of the detection, reduces the detection efficiency, and slows down the progress of the entire construction project. To this end, we propose a reinforced concrete precast beam bearing capacity detection device. Utility Model Content

[0025] Example 1:

The connection method and control method are public technologies and are not repeated here. A base 4 is provided at both ends of the base 2 near the distribution beam 3, and a support 5 for supporting the precast beam is installed on the base 4. The interval between the two groups of supports 5 is greater than the length of the distribution beam 3.

[0027] Furthermore, the two groups of supports 5 are both provided with positioning components capable of positioning the prefabricated beams on the side away from each other.

[0028] Furthermore, an adjustment control component capable of adjusting the positioning components is provided between the two groups of positioning components.

[0029] Furthermore, the positioning assembly is provided with a locking assembly capable of locking the positioning assembly.

[0030] Furthermore, hydraulic devices are provided at the bottom of the adjustment control assembly and the locking assembly, and the hydraulic devices are controlled by external control equipment. The connection method and control method are public technologies and will not be described in detail here.

[0031] In this embodiment, the adjustment control component is controlled by a hydraulic device to be raised and lowered, so that after the adjustment control component adjusts the positioning component to a suitable position, another hydraulic device is used to control the locking component to be adjusted, thereby locking the positioning component.

[0032] Furthermore, the positioning assembly includes a limit plate 7, a limit rod 12, a limit sleeve 13 and a fixing ring 14. The limit plate 7 is arranged on the side where the two groups of supports 5 are away from each other. The limit rod 12 is fixedly installed on the side of the limit plate 7 close to the support 5, and the limit rod 12 slides away from the limit plate 7 and passes through the corresponding position wall of the support 5 to extend to the area where the two groups of supports 5 are close to each other. The limit sleeve 13 is arranged on the side where the two groups of supports 5 are close to each other. There are two groups of limit sleeves 13. The two groups of limit sleeves 13 and the two groups of limit rods 12 correspond to each other, and the limit rod 12 slides away from the support 5 and passes through the corresponding position wall of the limit sleeve 13. The fixing ring 14 is fixedly installed on the limit sleeve 13. There are at least two groups of fixing rings 14, and the bottom of the fixing ring 14 is fixedly installed on the base 2.

[0033] In this embodiment, the two ends of the prefabricated beam can be limited by the two groups of supports 5 after adjustment by the adjustment control component.

[0034] Furthermore, the adjustment and control assembly includes a lifting column 9, an auxiliary groove 10, a fixed side plate 17, a pushing rod 18 and a fixed rod 19. The lifting column 9 is installed on the base 2, and the lifting column 9 is arranged in the middle of the area between the two groups of supports 5. The auxiliary groove 10 is opened on the side wall of the lifting column 9, and the two ends of the auxiliary groove 10 correspond to the two groups of limiting sleeves 13 respectively. The fixed side plate 17 is fixedly installed on both sides of the limiting rod 12 close to the lifting column 9. The pushing rod 18 is arranged between the two groups of fixed side plates 17. The pushing rod 18 extends to the inside of the auxiliary groove 10 on the lifting column 9 away from the limiting rod 12. The fixed rod 19 is fixedly installed on the inner side of the auxiliary groove 10, and the two groups of pushing rods 18 are movably mounted on the fixed rod 19 at one end away from the limiting rod 12.

[0035] Furthermore, a hydraulic device is provided on the inner side or bottom of the base 2 at a position corresponding to the lifting column 9. The bottom of the lifting column 9 and the output end of the hydraulic device are connected to each other. The hydraulic device connected to the lifting column 9 is controlled by an external control device. The connection method and control method are both public technologies and will not be elaborated here.

[0036] In this embodiment, the lifting column 9 is controlled to be raised and lowered by a hydraulic device, so that the limit rod 12 can be effectively pushed or pulled by the pushing rod 18 during the rising or falling process of the lifting column 9, thereby effectively driving the limit plate 7 to move and adjust. At the same time, this adjustment method can effectively drive the two sets of limit plates 7 to be adjusted synchronously, so that the prefabricated beam can be effectively positioned and restricted in the middle position after being limited by the limit plate 7, so that the pressure it is subjected to can be effectively concentrated during the bearing capacity test, which can greatly improve the accuracy of its bearing capacity test.

[0037] In this embodiment, the fixing ring 14 on the limiting sleeve 13 can effectively support and limit the limiting sleeve 13, so that the limiting rod 12 will not have an angular deviation when moving.

[0038] Furthermore, the locking assembly includes a support plate 6, a card rod 15 and a card slot 16. The support plate 6 is arranged at the bottom of the limit rod 12. Several groups of card slots 16 are spaced apart on the limit rod 12. Several groups of card rods 15 are fixedly installed at intervals corresponding to the position of the limit rod 12 on the top of the support plate 6. The outer diameter of the card rod 15 is adapted to the inner diameter of the card slot 16. There are at least three groups of card rods 15, and the number of card slots 16 is set according to actual usage requirements.

[0039] Furthermore, a hydraulic device is also provided on the inner side or bottom of the base 2 at a position corresponding to the support plate 6. The bottom of the support plate 6 and the output end of the hydraulic device are connected to each other. The hydraulic device connected to the support plate 6 is controlled by an external control device. The connection method and control method are both public technologies and will not be repeated here.

[0040] In this embodiment, through the slot 16 on the limit rod 12 and the latching rod 15 on the support plate 6, when the adjustment control component adjusts the limit rod 12 to the specified position, the support plate 6 is controlled to rise through the hydraulic device, so that the latching rod 15 can be snapped into the slot 16 on the limit rod 12, thereby completing the limiting of the limit rod 12.

[0041] Furthermore, retaining plates 11 are fixedly mounted on both sides of the top of the support plate 6 .

[0042] In this embodiment, through the limiting plates 11 on both sides of the support plate 6, when the bearing capacity is tested after the limiting rod 12 is limited, the prefabricated beam will break when the bearing capacity is far lower than the design value, thereby effectively limiting its two sides. When the distribution beam 3 is lifted by the hydraulic device, the prefabricated beam will not fall due to the inability of the support point to effectively support the prefabricated beam due to the breakage.

[0043] In this embodiment, after the clamping rod 15 can extend through the clamping slot 16 to above the limit rod 12, when the prefabricated beam is broken, it can be effectively supported by multiple groups of clamping rods 15. At the same time, the support space formed by multiple groups of clamping rods 15 allows the broken prefabricated beam to be moved out by forklifts and other related equipment.

[0044] Furthermore, an elastically adjustable adjustment plate 8 is fixedly installed at an angle on one side of the limiting plate 7 close to the support 5 .

[0045] In this embodiment, the adjustment plate 8 on the limit plate 7 makes it unnecessary to adjust the limit plate 7 to accurately fit the size of the prefabricated beam. On the one hand, it can facilitate the placement of the prefabricated beam, and on the other hand, it can also facilitate the positioning of the positioning component.

[0046] Example 2:

[0047] like Figure 5 As shown, a reinforced concrete precast beam bearing capacity detection device includes a clamping rod 15, the height of the clamping rod 15 gradually decreases from the side close to the limit rod 12 to the side close to the lifting column 9, and the height difference change of multiple groups of clamping rods 15 can form an inclined or curved curve.

[0048] In this embodiment, the clamping rods 15 on both sides are gradually lowered toward the side close to the lifting column 9, so that the broken prefabricated beam can be supported by the inclined surface or arc curve formed by the height changes of multiple groups of clamping rods 15, so that the prefabricated beam can be effectively supported efficiently.

[0049] The working principle and use process of this utility model:

[0050] In use, the positioning assembly is moved to the preset position by controlling the adjusting control assembly through the control device, and then the positioning assembly is locked and fixed by controlling the locking assembly through the control device, after the prefabricated beam is moved between the two sets of limiting plates 7 by a forklift or other related equipment, the hydraulic device is controlled by the control device to drive the distribution beam 3 to press the prefabricated beam at a preset pressure, when the detection work is completed, if the detection is qualified (i.e. the prefabricated beam has no obvious damage or no damage), the distribution beam 3 is raised back by adjusting the related hydraulic device through the control device, and the positioning assembly is lowered to be separated from the limiting rod 12, at this time, the prefabricated beam is moved out by a forklift or other related equipment, if the detection is unqualified (i.e. the prefabricated beam has obvious damage or is broken), the distribution beam 3 is raised back by adjusting the related hydraulic device through the control device, and the positioning assembly is not lowered, at this time, the broken prefabricated beam is fixed and then moved out stably, and then the positioning assembly is lowered to be separated from the limiting rod 12.

[0051] The two sets of limiting plates 7 on the positioning assembly can be adjusted synchronously, so that the prefabricated beam of any specification can be positioned, and the stress point of the prefabricated beam can be quickly and effectively limited and centered, the effectiveness of the detection data of the prefabricated beam during load bearing capacity detection can be effectively improved, and deviation of the load bearing capacity detection data caused by repeated adjustment of the prefabricated beam and non-centering of the stress point of the prefabricated beam during prefabricated beam detection can be avoided.

[0052] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to obtain equivalent embodiments. However, any simple modification, equivalent change and modification of the above embodiments made according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
