Description

Technical Field

[0001] This utility model relates to the field of building structure testing technology, specifically to a roof truss load testing platform. Background Technology

[0002] With the rapid development of the construction industry, modular buildings are becoming increasingly common. Among them, the roof truss, as an important component of the building structure, directly affects the overall stability of the building in terms of its load-bearing capacity and safety. Currently, the testing technology for roof truss structures mainly includes static load testing, dynamic load testing, and non-destructive testing methods. In the existing testing methods, the roof truss is placed vertically on the bottom support columns and raised columns using a crane. The two sides of the roof truss are supported by the support columns to keep the roof truss in a vertical state. First, the concrete slabs are weighed by placing a weighing plate on the tower crane. Then, the tower crane lifts the concrete slabs and places them on the roof truss. The deflection value will change when the tower crane lifts the concrete slabs and places them on the roof truss. The deflection measuring instrument measures the load performance at both ends of the bottom of the roof truss and in the middle part.

[0003] During the inspection process, roof trusses of different widths need to be moved to different locations. This requires the use of a crane and steel cables to move them. Since the raised columns will sway left and right after being raised, and the raised columns are large in size and weight, it is inconvenient to correct them. The correction process also requires manual intervention, which makes the adjustment process cumbersome and less safe.

[0004] Therefore, it is necessary to invent a roof truss load testing platform to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a roof truss load testing platform to solve the problems of cumbersome adjustment process and low safety in the technology of raising columns.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a roof truss load testing platform, comprising a testing platform and a roof truss body. A gantry crane that can move left and right is installed on the upper side of the testing platform. A weighbridge is fixedly installed at the left end of the testing platform. Three sets of raised blocks are provided on the surface of the testing platform. An adjustment component is provided between the front and rear sets of raised blocks and the testing platform. The adjustment component includes a plug groove, a positioning rod, a mounting plate, a positioning roller, a linear guide rail, a positioning groove, and a positioning hole. The roof truss body is erected on the upper side of the raised blocks. Multiple sets of concrete slabs overlap the upper side of the roof truss body. A deflection measuring instrument is provided on the lower side of the roof truss body. A support frame is provided on the side of the roof truss body.

[0007] By adopting the above technical solution, during the testing process, the roof truss body is placed vertically on the raised column using a gantry crane. The two sides of the roof truss body are supported by a support frame to keep it in a vertical state. Then, the concrete slabs are first placed on a weighbridge using the gantry crane for weighing, and then the concrete slabs are lifted and placed on the upper side of the roof truss body. At this time, the deflection value of the roof truss body will change. The deflection measuring instrument measures the load performance at both ends of the bottom of the roof truss body and in the middle part respectively.

[0008] Optionally, multiple sets of mounting plates are fixedly connected to the lower surfaces of both the front and rear sets of the raised blocks, and multiple sets of positioning rollers are rotatably connected to the inner side of the mounting plates.

[0009] By adopting the above technical solution, the mounting plate, together with the positioning rollers, facilitates the movement of the raised block.

[0010] Optionally, the surface of the detection platform is fixedly connected to multiple sets of linear guide rails, the upper surface of the linear guide rails is provided with positioning grooves, and the positioning rollers are engaged inside the positioning grooves.

[0011] By adopting the above technical solution, the positioning roller rolls inside the positioning groove, and the positioning groove limits the movement position of the positioning roller, thereby maintaining the movement direction of the shim block.

[0012] Optionally, multiple sets of insertion slots are provided inside the front and rear sets of the raised blocks, and positioning rods are inserted into the insertion slots.

[0013] By adopting the above technical solution, a handle is connected to the upper end of the positioning rod, which makes it easy to pull the positioning rod out of the insertion slot.

[0014] Optionally, the surface of the detection platform is provided with multiple sets of positioning holes, and the lower end of the positioning rod is inserted and fixed into the positioning holes.

[0015] By adopting the above technical solution, after the positioning rod is inserted into the positioning hole through the insertion slot, the position of the shim block is limited, thereby improving the stability of the shim block during the testing process.

[0016] Optionally, the support frame includes a support plate, a connecting block, a first support tube, a second support tube, a fixing block, a locking sleeve, a locking screw, and a locking block.

[0017] By adopting the above technical solution, the first support pipe and the second support pipe work together to support both sides of the roof truss body.

[0018] Optionally, two sets of connecting blocks are fixedly connected to both the left and right sides of the support plate, and a first support tube is rotatably connected to the upper side of each connecting block on both the left and right sides. A reinforcing plate is fixedly connected between the two sets of first support tubes on the same side. The second support tube is slidably connected to the interior of the first support tube, and the fixing block is installed at the upper end of the first support tube.

[0019] By adopting the above technical solution, the second support tube slides up and down inside the first support tube, which facilitates the support of roof trusses of different heights. The first support tube can rotate left and right, making it easy to fold and store when not in use, thus improving ease of use.

[0020] Optionally, the locking sleeve is rotatably connected to the sidewall of the two sets of first support tubes on the same side, the locking screw is inserted into the inside of the left and right sets of locking sleeves, and the locking block is threadedly connected to the right end of the locking screw.

[0021] By adopting the above technical solution, the locking screw and locking block are used to lock and fix the first support pipes on both sides, thereby providing stable support for the roof truss.

[0022] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0023] 1. This utility model uses positioning rollers, linear guides and positioning grooves to facilitate the movement of the shim block, improve the convenience and safety of the shim block movement, and effectively improve the stability of the shim block during the testing process by inserting the positioning rod through the insertion groove into the positioning hole, thus avoiding the problems of displacement and tipping.

[0024] 2. This utility model uses a foldable and telescopic support frame to support both sides of the roof truss. The second support tube slides up and down inside the first support tube, which facilitates the support of roof truss bodies of different heights. The first support tube can rotate left and right, which makes it easy to fold and store it when not in use, thus improving the convenience of use. Attached Figure Description

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0035] This utility model provides, for example Figures 1 to 5 The roof truss load testing platform shown includes a testing platform 1 and a roof truss body 2. A gantry crane 11 that can move left and right is installed on the upper side of the testing platform 1. A weighbridge 12 is fixedly installed on the left end of the testing platform 1. Three sets of raised blocks 13 are provided on the surface of the testing platform 1. An adjustment component is provided between the front and rear sets of raised blocks 13 and the testing platform 1. The adjustment component includes a plug groove 131, a positioning rod 132, a mounting plate 133, a positioning roller 134, a linear guide rail 14, a positioning groove 141, and a positioning hole 15. The roof truss body 2 is erected on the upper side of the raised blocks 13. Multiple sets of concrete slabs 3 overlap the upper side of the roof truss body 2. A deflection measuring instrument 4 is provided on the lower side of the roof truss body 2. A support frame 5 is provided on the side of the roof truss body 2.

[0036] In the process of use, the shim block 13 is first adjusted to a position that matches the roof truss body 2 by adjusting the components. Then, the two sets of roof truss bodies 2 are hoisted onto the upper side of the shim block 13 by the gantry crane 11, and the roof truss bodies 2 are vertically erected on the upper side of the shim block 13. Next, the support frame 5 is installed on the side of the roof truss body 2 to support the roof truss body 2 and ensure the stability of the roof truss body 2. Then, multiple sets of deflection measuring instruments 4 are installed at both ends and the middle of the lower side of the roof truss body 2. After all are installed, the gantry crane 11 is started again. The gantry crane 11 first hoists the concrete slab 3 onto the upper side of the weighbridge 12 to weigh the concrete slab 3. Then, the concrete slab 3 is hoisted onto the upper side of the two sets of roof truss bodies 2. Multiple sets of concrete slabs 3 are then overlapped on the upper side of the roof truss body 2 to test the roof truss body 2.

[0037] See Figures 2 to 5 Multiple sets of mounting plates 133 are fixedly connected to the lower surfaces of the front and rear sets of raised blocks 13. Multiple sets of positioning rollers 134 are rotatably connected to the inner side of the mounting plates 133. Multiple sets of linear guide rails 14 are fixedly connected to the surface of the detection platform 1. Positioning grooves 141 are opened on the upper surface of the linear guide rails 14. Positioning rollers 134 are locked in the inner side of the positioning grooves 141. Multiple sets of insertion grooves 131 are opened inside the front and rear sets of raised blocks 13. Positioning rods 132 are inserted into the insertion grooves 131. Multiple sets of positioning holes 15 are opened on the surface of the detection platform 1. The lower end of the positioning rod 132 is inserted into the positioning hole 15 and fixed.

[0038] Specifically, during the adjustment of the shim block 13, firstly, multiple sets of positioning rods 132 are removed from the inside of the positioning holes 15. Then, the steel cable in the gantry crane 11 is fixed to the shim block 13. Next, the moving module in the gantry crane 11 is activated. The moving module in the gantry crane 11 pulls the shim block 13 to one side, so that the shim block 13 and the positioning roller 134 cooperate to slide to one side. Thus, it is not necessary to raise the shim block 13, thereby avoiding the rotation of the shim block 13. The shim block 13 is directly moved to one side, improving the convenience and safety of adjusting the position of the shim block 13.

[0039] After the shim block 13 is moved to the designated position, the positioning rod 132 is passed through the insertion slot 131 again and inserted into the positioning hole 15 to fix the position of the shim block 13.

[0040] See Figure 6 and Figure 7 The support frame 5 includes a support plate 51, a connecting block 52, a first support tube 53, a second support tube 55, a fixing block 56, a locking sleeve 57, a locking screw 58, and a locking block 59. Two sets of connecting blocks 52 are fixedly connected to both the left and right sides of the support plate 51. The first support tube 53 is rotatably connected to the upper side of the connecting blocks 52 on both the left and right sides. A reinforcing plate 54 is fixedly connected between the two sets of first support tubes 53 on the same side. The second support tube 55 is slidably connected to the inside of the first support tube 53. The fixing block 56 is installed on the upper end of the first support tube 53. The locking sleeve 57 is rotatably connected to the side wall of the two sets of first support tubes 53 on the same side. The locking screw 58 is inserted into the inside of the two sets of locking sleeves 57 on the left and right sides. The locking block 59 is threadedly connected to the right end of the locking screw 58.

[0041] In addition, during the installation of the support frame 5, the first support pipe 53 and the second support pipe 55 on both sides are first rotated to the sides. Then, the support plate 51, the first support pipe 53 and the second support pipe 55 are moved to the lower side of the roof truss body 2. Then, the first support pipe 53 and the second support pipe 55 are rotated upward so that they are diagonally supported on the side of the roof truss body 2. According to the height of the roof truss body 2, the second support pipe 55 is pulled out or retracted upward to adjust the height of the support frame 5.

[0042] Next, the locking screw 58 is passed through the locking sleeves 57 on both sides in sequence, and the locking block 59 is threaded to one end of the locking screw 58. The locking screw 58 is used to lock and fix the first support tubes 53 on both sides, thereby improving the stability of the support.

[0043] Meanwhile, after the test is completed, the second support tube 55 can be completely retracted into the interior of the first support tube 53. Then, the first support tubes 53 on both sides can be rotated inward to fold the support frame 5 together, making it easier to move and transport the support frame 5.

[0044] The working principle of this utility model is as follows: The positioning roller 134, linear guide rail 14 and positioning groove 141 cooperate to facilitate the movement of the shim block 13, improving the convenience and safety of the movement of the shim block 13. Furthermore, by inserting the positioning rod 132 through the insertion groove 131 into the positioning hole 15, the stability of the shim block 13 during the testing process is effectively improved, avoiding the problems of displacement and tipping. The roof truss body 2 is supported on both sides by using a foldable and telescopic support frame 5. The second support tube 55 slides up and down inside the first support tube 53, which facilitates the support of roof truss bodies 2 of different heights. Moreover, the first support tube 53 can rotate left and right, making it easy to fold and store when not in use, improving the convenience of use and movement.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
