Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a concrete testing device for building construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of an engineering project, which is the process of building various types of buildings. Concrete is a commonly used construction material in construction sites. Since the quality of concrete affects the quality of the building to a certain extent, a concrete pressure testing machine is needed to test the hardness of the concrete.

[0003] In traditional concrete pressure testing machines, the concrete test block is usually placed at the bottom of the pressure block, and then the hydraulic cylinder is used to drive the pressure block to move downward or upward to compress the concrete test block, thereby completing the test of its hardness.

[0004] However, after the concrete test blocks are tested, the debris generated from their breakage often needs to be manually cleaned up. This not only increases the labor intensity of the operators but also significantly reduces the testing efficiency. Secondly, traditional concrete pressure testing machines are not convenient for positioning concrete test blocks. When the test block is installed in a misaligned position, it will cause uneven pressure distribution on the contact surface between the pressure block and the test block. This non-uniform stress state will not only cause the test data to be distorted but also fail to accurately reflect the true mechanical properties of the concrete test block, thus affecting the quality and safety of the entire building construction. Utility Model Content

[0005] This utility model provides a concrete testing device for building construction. The device uses an adjusting component to rotate the housing, which facilitates the discharge of concrete test block debris inside, thereby improving the debris cleaning efficiency. At the same time, the device uses a fixing component to fix the concrete test block inside the concrete pressure testing machine, which can improve the stability of the test and prevent the positional deviation from affecting the test quality. This solves the problems mentioned in the background art of concrete pressure testing machines that are not convenient for positioning concrete test blocks and cleaning the debris inside the concrete test blocks.

[0006] This utility model provides the following technical solution: A concrete testing device for building construction includes a housing and a concrete pressure testing machine fixedly installed on the housing. It further includes: a transmission rod rotatably connected to the housing, wherein a base is fixedly connected to the transmission rod, and an adjusting component is provided on the base. When the adjusting component is in operation, the housing tends to rotate along the axis of the transmission rod; and a fixing component disposed on the concrete pressure testing machine, the fixing component being used to clamp and position concrete test blocks inside the concrete pressure testing machine.

[0007] As a preferred embodiment of the present invention, the adjusting component includes a positioning rod fixedly connected to the base, and a cylinder is movably sleeved on the positioning rod, with the output end of the cylinder being rotatably connected to the housing.

[0008] As a preferred embodiment of this utility model, the fixing component includes a threaded sleeve fixedly connected to a concrete pressure testing machine, a lead screw is threadedly connected to the inner cavity of the threaded sleeve, and a positioning block is fixedly connected to one end of the lead screw.

[0009] As a preferred technical solution of this utility model, a torsion block is fixedly connected to the end of the lead screw away from the positioning block, and the surface of the torsion block is provided with an anti-slip groove.

[0010] As a preferred embodiment of this utility model, at least two support rods are fixedly connected to the base, and the two support rods are symmetrically arranged about the center line of the base.

[0011] As a preferred embodiment of this utility model, the shell is U-shaped, and the opening end of the shell tends to contract inward.

[0012] Compared with the prior art, this utility model provides a concrete testing device for building construction, which has the following beneficial effects: 1. In this concrete testing device for building construction, by setting the adjusting component, after the concrete test block is tested under pressure, the output end of the cylinder drives the shell to move, so that the shell rotates around the axis of the transmission rod. At this time, the shell is in an inclined state, and the residual concrete debris inside is smoothly slid down along the inclined surface by using gravity, so as to realize the automatic cleaning of the testing chamber, thereby effectively improving the testing efficiency of the concrete test block.

[0013] 2. In this concrete testing device for building construction, by setting up a fixing component, rotating the torsion block causes two lead screws to drive two positioning blocks to move in opposite directions, which can clamp and position concrete test blocks of different sizes, avoiding the problem of position displacement of concrete test blocks during the pressure testing process, thus affecting the accuracy of the test.

[0014] 3. In this concrete testing device for building construction, the support rods can be used to support and position the shell, thereby improving the stability of the concrete pressure testing machine.

[0015] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model positions the concrete test block using a fixing component, ensuring uniform and sufficient contact between the concrete pressure testing machine and the concrete test block, effectively avoiding detection errors caused by uneven contact. At the same time, after the test is completed, the angle of the shell is adjusted using an adjusting component, allowing the residual concrete debris inside the shell to slide off naturally under gravity, achieving efficient and convenient automatic cleaning. This not only greatly saves the time and effort of manual cleaning, but also effectively improves the efficiency of subsequent hardness testing of concrete test blocks. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Reference Figures 1-6A concrete testing device for building construction includes a housing 1 and a concrete pressure testing machine 2 fixedly installed on the housing 1. The concrete pressure testing machine 2 is a CDT1000 concrete pressure testing machine 2. The housing 1 is U-shaped, and the open end of the housing 1 tends to taper inward, which can protect against splashed concrete test block debris and facilitate the discharge of internal debris. It also includes a transmission rod 3, which is rotatably connected to the housing 1. A base 4 is fixedly connected to the transmission rod 3. An adjusting component is provided on the base 4. When the adjusting component is working, the housing 1 tends to rotate along the axis of the transmission rod 3 for adjusting the angle of the housing 1, thereby facilitating the discharge of internal concrete debris. A fixing component is provided on the concrete pressure testing machine 2 for clamping and positioning concrete test blocks of different sizes inside the concrete pressure testing machine 2.

[0021] Specifically, by positioning the concrete test block using the fixing component, it is ensured that a uniform and sufficient contact is formed between the concrete pressure testing machine 2 and the concrete test block, effectively avoiding detection errors caused by uneven contact. At the same time, after the test is completed, the angle of the shell 1 is adjusted using the adjusting component, allowing the residual concrete debris inside the shell 1 to slide off naturally under the action of gravity, achieving efficient and convenient automatic cleaning. This not only greatly saves the time and effort of manual cleaning, but also effectively improves the efficiency of subsequent hardness testing of concrete test blocks.

[0022] The adjusting component includes a positioning rod 5 fixedly connected to the base 4, and a cylinder 51 is movably sleeved on the positioning rod 5. The output end of the cylinder 51 is rotatably connected to the housing 1 through a pin.

[0023] Specifically, by adjusting the settings, after the concrete test block is tested under pressure, the output end of the cylinder 51 drives the housing 1 to move, causing the housing 1 to rotate around the axis of the transmission rod 3. At this time, the housing 1 is in an inclined state, and the residual concrete debris inside is smoothly slid down along the inclined surface by using gravity, thereby realizing the automatic cleaning of the test chamber and effectively improving the testing efficiency of the concrete test block.

[0024] The fasteners include two threaded sleeves 7 fixedly connected to the concrete pressure testing machine 2, which are symmetrically installed on the outer shell of the concrete pressure testing machine 2. The inner cavity of the threaded sleeve 7 is threadedly connected to a lead screw 71. One end of the lead screw 71 passes through the outer shell of the concrete pressure testing machine 2 and is fixedly connected to a positioning block 72. The end of the lead screw 71 away from the positioning block 72 is fixedly connected to a torsion block. The surface of the torsion block is provided with anti-slip grooves to facilitate the operator to adjust the position of the positioning block 72.

[0025] Specifically, by setting the fixing component, rotating the torsion block causes the two lead screws 71 to drive the two positioning blocks 72 to move in opposite directions, which can clamp and position concrete test blocks of different sizes, avoiding the problem of position displacement of concrete test blocks during the pressure test, thus affecting the accuracy of the test.

[0026] Two support rods 6 are fixedly connected to the base 4. The support rods 6 are T-shaped and the two support rods 6 are symmetrically arranged about the center line of the base 4.

[0027] Specifically, the support rod 6 can support and position the housing 1, thereby improving the stability of the concrete pressure testing machine 2.

[0028] In this invention, when testing the hardness of a concrete test block, the concrete test block is first placed centered in the test chamber of the concrete pressure testing machine 2. Then, two torsion blocks are rotated, which in turn drive two lead screws 71 to rotate. As the two lead screws 71 rotate inside the threaded sleeve 7, they drive two positioning blocks 72 to move in opposite directions. After the two positioning blocks 72 move in opposite directions and come into contact with the concrete test block, they can be fixed, effectively avoiding the problem of the concrete test block shifting under pressure, which would affect the accuracy of the test.

[0029] After the concrete test block is positioned, the operator starts the hydraulic cylinder on the concrete pressure testing machine 2 through the external control switch. The output end of the hydraulic cylinder drives the pressure block to descend at a preset speed, applying an axial compressive load to the test block until it is damaged. During this period, the pressure sensor collects test data in real time and transmits it to the control system.

[0030] After the concrete test block is tested, the operator rotates the torsion block to move the two positioning blocks 72 in the opposite direction, releasing the limit on the test block. Then, the cylinder 51 is started using an external control switch. When the output end of the cylinder 51 moves, it drives the housing 1 to rotate around the axis of the transmission rod 3. When the tilt angle of the housing 1 reaches the preset value, the residual concrete debris inside automatically slides off under the action of gravity, thereby realizing the automatic cleaning of the debris. After the cleaning operation is completed, the cylinder 51 reverses its movement to restore the housing 1 to the horizontal test position, and the subsequent testing of the concrete test block can be carried out.

[0031] Components not described in detail in this article are existing technologies.
