DETAILED DESCRIPTION

[0024] The embodiment of the present invention provides a placement platform for testing the structural performance of horizontal prefabricated components, such as Figures 1-5 As shown, it includes a base 11, a guide rail assembly, an operating platform 14, four sets of mobile platforms 15, a mobile mechanism and four sets of support assemblies. The guide rail assembly is fixedly installed on the upper surface of the base 11. Figure 3 As shown, the guide rail assembly includes two sets of horizontal guide rails 12 located in the horizontal direction and a vertical guide rail 13 located in the vertical direction. The two sets of horizontal guide rails 12 are symmetrically arranged on both sides of the vertical guide rail 13. Figure 2 As shown, the operating platform 14 is arranged between the horizontal guide rail 12 and the vertical guide rail 13, four groups of mobile platforms 15 are respectively arranged on the horizontal guide rail 12 and the vertical guide rail 13, the moving mechanism is arranged between the mobile platform 15 and the guide rail assembly, and four groups of support assemblies are respectively arranged on the upper side of the mobile platform 15, and the support assemblies are used to support the prefabricated floor slabs.

[0025] A plurality of mounting feet are provided on the lower side of the base 11, and the mounting feet of the base 11 are mounted on the maintenance foundation through expansion bolts.

[0026] The total length of the horizontal guide rail 12 is 12m, the total length of the vertical guide rail 13 is 6m, the spacing between the guide rails on the same side is 5m, and the operating platform 14 is located at the center between the horizontal guide rail 12 and the vertical guide rail 13. The upper part of the operating platform 14 is the operating space. The operating platform 14 can prevent the test floor from breaking and falling to the ground directly, and can place test instruments, making it convenient for staff to place and operate the instruments.

[0027] like Figure 5As shown in the figure, the moving mechanism includes a wheel baffle 20 and wheels 21. The wheels 21 are respectively arranged on the horizontal guide rail 12 and the vertical guide rail 13. Four wheels 21 are arranged on the lower side of each moving platform 15. The wheel baffles 20 are respectively arranged on both axial sides of the wheels 21 and fixedly installed at the lower end of the moving platform 15. Grooves adapted to the horizontal guide rail 12 and the vertical guide rail 13 are provided on the inner sides of the wheels 21.

[0028] The support assembly includes a triangular seat 25, a reinforcing frame 26, a reinforcing straight rod 27 and an adjusting assembly. The triangular seat 25 is arranged on the upper side of the moving platform 15. Two triangular seats 25 are correspondingly arranged on the upper side of each moving platform 15. The triangular seats 25 are symmetrically arranged on both sides of the moving platform 15. The reinforcing frame 26 is fixedly arranged between the triangular seat 25 and the upper surface of the moving platform 15. The reinforcing straight rod 27 is arranged between the two triangular seats 25 on both sides and fixedly connected to the lower moving platform 15. The adjusting assembly is arranged on the upper inner side of the triangular seat 25 and inside the reinforcing straight rod 27.

[0029] The height from the upper end surface of the triangular seat 25 to the ground is 1.5 m. The triangular seat 25 and the reinforcing frame 26 can ensure that the device remains stable as the bearing capacity gradually increases during the test, and guarantee the stability of the test floor slab during the strengthening test.

[0030] The upper side of the outer circular surface of the reinforcing straight rod 27 is at the same height as the upper end surface of the triangular seat 25. The reinforcing straight rod 27 is divided into a vertical part and a horizontal part.

[0031] The support assembly includes a rotating groove 28 and a rotating roller 29. The rotating groove 28 is opened on the upper inner side of the triangular seat 25 and the upper inner side of the reinforcing straight rod 27. The rotating grooves 28 located in the horizontal part of the reinforcing straight rod 27 are respectively located on both sides of the vertical part of the reinforcing straight rod 27. The rotating roller 29 is rotatably connected between the inner walls of the rotating groove 28.

[0032] The outer circular surface of the rotating roller 29 is at the same height as the outer circular surface of the reinforcing straight rod 27. A sponge pad is sleeved on the outer circular surface of the rotating roller 29. When the test floor slab is placed on the triangular seat 25, due to the gravity of the test floor slab, it will undergo a slight deformation when it is carried on the triangular seat 25. At this time, since the frictional force between the sponge pad on the outer surface of the rotating roller 29 and the test floor slab is greater than the frictional force between the reinforcing straight rod 27 and the test floor slab, the deformation of the test floor slab will drive the rotating roller 29 to rotate a certain angle, thereby balancing the displacement generated by the test floor slab and improving the accuracy of the test results.

[0033] As Figure 4 shown in the figure, a threaded groove is provided in the moving platform 15 between the two triangular seats 25 on both sides. A brake rod 17 is threadedly connected in the threaded groove of the moving platform 15. The upper end surface of the brake rod 17 extends to the upper side of the moving platform 15, and the lower end surface of the brake rod 17 extends to the lower side of the moving platform 15. A brake knob 16 is fixedly connected to the upper end surface of the brake rod 17.

[0034] When the staff needs to inspect the horizontal precast components, first move the mobile platform 15, so that the mobile platform 15 moves along the horizontal guide rail 12 or the vertical guide rail 13 through the wheels 21, and then adjust the spacing according to the dimensions required for the one-way and two-way tests of the fabricated floor slab, the horizontal test of the beam or the staircase. When conducting a one-way test, the mobile platform 15 located on the upper side of the horizontal guide rail 12 can be used for the test. When a two-way test is required, the mobile platforms 15 on the horizontal guide rail 12 and the vertical guide rail 13 need to work together for the test.

[0035] When the mobile platform 15 is adjusted to the appropriate distance by moving, the staff manually rotates the brake knob 16. The brake knob 16 drives the brake lever 17 to rotate, and then cooperates with the screw descent inside the mobile platform 15, so that the lower end surface of the brake lever 17 abuts against the upper surface of the base 11, fixing the mobile platform 15 and ensuring that it no longer moves, enhancing the stability.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
