Description
Technical Field
[0001] This utility model belongs to the field of molding device technology, specifically a molding device for easily molding mortar bonding strength. Background Technology
[0002] The mortar bond strength test is an important test to evaluate the degree of bond between mortar and substrate. This test usually involves the preparation and curing of the specimen and the use of specialized equipment such as a tensile testing machine to determine the tensile bond strength.
[0003] By measuring the load and bond area at specimen failure, the bond strength can be calculated, thereby determining whether the putty and mortar meet the mechanical performance requirements. When bonding the putty and mortar with the cement block, a molding frame is required. The molded frame is placed on top of the cement block, and then the putty and mortar are poured into the molded frame to complete the preparation of the test block. However, when pouring the putty and mortar, the molded frame is not fixed on top of the test block, which makes the molded frame easy to move, resulting in deviations in the position of the putty and mortar being poured. Therefore, it needs to be improved. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-form mortar bonding strength forming device, comprising a base, with clamping blocks movably connected to the left and right sides of the top of the base, a cement test block body movably connected between the clamping blocks, a detachable forming frame movably connected to the top of the cement test block body, two clamping blocks, and mounting plates movably connected to the top of each clamping block. Mounting bolts are movably fitted inside the mounting plates, with the bottom ends of the mounting bolts penetrating the mounting plates and extending into the interior of the clamping blocks, threadedly engaging with the inner wall of the clamping blocks. The top of the mounting plates is fixedly connected to... The device has a side plate, with round rods fixedly installed inside both the front and rear ends of the side plate. A sliding plate is movably sleeved on the outer surface of the round rod. A clamping plate is fixedly connected to the inner side of the sliding plate. The outer surface of the clamping plate is movably connected to the side of the detachable molding frame. A connecting block is fixedly connected to the outer side of the sliding plate. A hinge rod is hinged inside the connecting block. A movable plate is hinged to the outer end of the hinge rod. An installation sleeve is fixedly connected to the outer side of the side plate. A rotating threaded rod is movably sleeved inside the installation sleeve. The other end of the rotating threaded rod passes through the movable plate and extends to the outside of the movable plate, where it is threadedly sleeved with the inner thread of the movable plate.
[0006] As a preferred embodiment of this utility model, a double-threaded rod is movably sleeved inside the base, and a rotating block is fixedly connected to the left end of the double-threaded rod.
[0007] As a preferred embodiment of this utility model, the left and right sides of the outer surface of the double threaded rod are threaded with movable blocks, the outer surface of the movable blocks is movably connected to the inner surface of the base, and the top of the movable blocks is fixedly connected to the bottom of the clamping block.
[0008] As a preferred embodiment of this utility model, push plates are movably installed inside both the front and back sides of the base, and limit blocks are fixedly connected to both the left and right sides of the push plates. The outer surface of the limit blocks is movably connected to the inner wall of the base.
[0009] As a preferred embodiment of this utility model, springs are fixedly connected to both the left and right sides of the bottom of the push plate, and the bottom of the springs is fixedly connected to the inner wall of the base.
[0010] As a preferred embodiment of this utility model, a lower connecting plate is fixedly connected to the bottom of both the front and back sides of the base, and a rotating bolt is threaded into the internal thread of the lower connecting plate.
[0011] As a preferred embodiment of this utility model, an upper connecting plate is fixedly connected to the outer surface of the push plate, and the inner wall of the upper connecting plate is movably sleeved with the outer surface of the rotating bolt.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model, by setting up clamping blocks, sliding plates, clamping plates, and moving plates, allows the operator to place the detachable molding frame on top of the cement test block body. By rotating the rotating threaded rod, the operator can cause the moving plate to move outward, thereby enabling the hinged rod to drive the two sliding plates to move in opposite directions through the connecting block. This allows the clamping plate to clamp and fix the detachable molding frame, thus preventing the detachable molding frame from moving during pouring. The operator can also rotate the rotating threaded rod in the opposite direction to cause the clamping plates to move in opposite directions, thereby releasing the fixing effect on the detachable molding frame. This makes it convenient for the operator to change detachable molding frames of different sizes.
[0014] 2. This utility model, by setting up a push plate, a spring, a lower connecting plate, and an upper connecting plate, allows the operator to fix the detachable molding frame after rotating the rotating bolt. This causes the rotating bolt to move upward inside the lower connecting plate until the top of the rotating bolt disengages from the upper connecting plate. At this point, the spring, under its restoring force, will push the push plate upward, thereby pushing the cement block body upward. This allows the top of the cement block body to fit more tightly with the bottom of the detachable molding frame, thus avoiding gaps between the detachable molding frame and the cement block body, and improving the molding quality of the experimental block.

[0021] 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.
[0022] like Figures 1 to 5As shown, this utility model provides an easy-to-form mortar bonding strength forming device, including a base 1. Clamping blocks 5 are movably connected to the left and right sides of the top of the base 1. A cement test block body 6 is movably connected between the clamping blocks 5. A detachable forming frame 13 is movably connected to the top of the cement test block body 6. There are two clamping blocks 5, and mounting plates 14 are movably connected to the top of each clamping block 5. Mounting bolts 16 are movably sleeved inside the mounting plates 14. The bottom end of the mounting bolts 16 penetrates the mounting plates 14 and extends into the interior of the clamping blocks 5, threadedly engaging with the inner wall of the clamping blocks 5. Side plates 15 are fixedly connected to the top of the mounting plates 14. The front and rear ends of the side plates 15... Inside each of the components, a round rod 17 is fixedly installed. A slide plate 18 is movably sleeved on the outer surface of the round rod 17. A clamping plate 19 is fixedly connected to the inner side of the slide plate 18. The outer surface of the clamping plate 19 is movably connected to the side of the detachable molding frame 13. A connecting block 20 is fixedly connected to the outer side of the slide plate 18. A hinge rod 21 is hinged inside the connecting block 20. A movable plate 22 is hinged to the outer end of the hinge rod 21. An installation sleeve 23 is fixedly connected to the outer side of the side plate 15. A rotating threaded rod 24 is movably sleeved inside the installation sleeve 23. The other end of the rotating threaded rod 24 passes through the movable plate 22 and extends to the outside of the movable plate 22 and is threadedly sleeved with the inside of the movable plate 22.
[0023] After the operator places the cement test block body 6 on top of the base 1, the two clamping blocks 5 clamp and fix the cement test block body 6. Then, the detachable molding frame 13 is placed on top of the cement test block body 6 and between the clamping plates 19. The operator then rotates the rotating threaded rod 24, thereby driving the moving plate 22 to move outward. This causes the hinge rod 21 to drive the two sliding plates 18 to move towards each other through the connecting block 20, which in turn causes the clamping plates 19 to move towards each other. This allows the clamping plates 19 to clamp and fix the detachable molding frame 13, thus preventing the detachable molding frame 13 from moving.
[0024] The base 1 has a double threaded rod 2 movably connected inside, and the left end of the double threaded rod 2 is fixedly connected to a rotating block 3.
[0025] As a technical optimization of this utility model, the operator can rotate the rotating block 3 to drive the double threaded rod 2 to rotate, and the threads on the left and right sides of the outer surface of the double threaded rod 2 are opposite.
[0026] The double threaded rod 2 has a moving block 4 threadedly connected to both the left and right sides of its outer surface. The outer surface of the moving block 4 is movably connected to the inner surface of the base 1, and the top of the moving block 4 is fixedly connected to the bottom of the clamping block 5.
[0027] As a technical optimization of this utility model, when the double threaded rod 2 rotates, it will drive the two moving blocks 4 to move in opposite directions, thereby driving the two clamping blocks 5 to move in opposite directions, and thus clamping and fixing the cement test block body 6.
[0028] The base 1 has push plates 7 installed movably inside both the front and back sides. Limiting blocks 8 are fixedly connected to the left and right sides of the push plates 7. The outer surface of the limiting blocks 8 is movably connected to the inner wall of the base 1.
[0029] As a technical optimization of this utility model, by setting a limiting block 8, the limiting block 8 can limit the push plate 7, so that the push plate 7 can move up and down, and prevent the push plate 7 from moving back and forth.
[0030] Among them, springs 9 are fixedly connected to the left and right sides of the bottom of the push plate 7, and the bottom of the springs 9 is fixedly connected to the inner wall of the base 1.
[0031] As a technical optimization of this utility model, by setting a spring 9, the spring 9 can push the push plate 7 upward under the elastic recovery action, thereby pushing the cement test block body 6 upward, so that the cement test block body 6 is tightly attached to the bottom of the detachable molding frame 13.
[0032] The base 1 has a lower connecting plate 10 fixedly connected to the bottom of both the front and back sides, and the lower connecting plate 10 has a rotating bolt 12 threaded inside.
[0033] As a technical optimization of this utility model, when the operator rotates the rotating bolt 12, the rotating bolt 12 will move upward or downward inside the lower connecting plate 10.
[0034] The upper connecting plate 11 is fixedly connected to the outer surface of the push plate 7, and the inner wall of the upper connecting plate 11 is movably sleeved with the outer surface of the rotating bolt 12.
[0035] As a technical optimization of this utility model, when the rotating bolt 12 moves upward, the push plate 7 will move upward under the elastic force of the spring 9.
[0036] Working principle and usage process of this utility model:
[0037] First, the operator rotates the rotating bolt 12 until its tip contacts the outer surface of the upper connecting plate 11. As the bolt 12 rotates, the upper connecting plate 11 moves downwards, causing the push plate 7 to move downwards into the base 1. The operator then places the cement block body 6 on top of the base 1. By rotating the rotating block 3, the double threaded rod 2 causes the two clamping blocks 5 to move in opposite directions, thus clamping and fixing the cement block body 6. Next, the operator places the detachable molding frame 13 on top of the cement block body 6. By rotating the rotating threaded rod 24, the moving plate 22 moves outwards, allowing the hinge rod 21 to drive the two sliding plates 18 to move in opposite directions via the connecting block 20. This, in turn, causes the two clamping plates 19 to move in opposite directions, clamping and fixing the detachable molding frame 13. This ensures the detachable molding frame 13 is stably placed on top of the cement block body 6, preventing displacement of the detachable molding frame 13 during putty and mortar pouring.
[0038] After the detachable molding frame 13 is fixed, the operator can rotate the rotating bolt 12 in the opposite direction to make the rotating bolt 12 move upward inside the lower connecting plate 10 until the top of the rotating bolt 12 disengages from the upper connecting plate 11. At this time, the spring 9 will push the push plate 7 upward under the elastic recovery action, so that the push plate 7 applies an upward force to the cement block body 6, thereby making the top of the cement block body 6 fit more tightly with the bottom of the detachable molding frame 13, thus avoiding gaps between the detachable molding frame 13 and the cement block body 6, thereby improving the molding quality of the experimental block.
[0039] When the mortar has solidified and the detachable molding frame 13 needs to be removed, the rotating block 3 can be rotated again, causing the rotating block 3 to drive the clamping block 5 to move in opposite directions. This causes the clamping block 5 to move the mounting plate 14 outward, allowing the clamping plate 19 to move the clamped detachable molding frame 13 outward, thus splitting the detachable molding frame 13 into two, thereby completing the demolding. The operator can then remove the mounting bolts 16 to remove the mounting plate 14 as a whole.
