Description

Technical Field

[0001] The present invention belongs to the field of construction, relates to support positioning technology, and specifically is a support positioning device for concrete beams and columns at building deformation joints. Background Art

[0002] Buildings refer to assets constructed artificially and belong to the category of fixed assets, including two major categories: houses and structures. A house refers to an engineering building for people to live, work, study, produce, operate, entertain, store items, and carry out other social activities. Different from buildings are structures, which refer to engineering buildings other than houses, such as walls, roads, dams, wells, tunnels, water towers, bridges, and chimneys.

[0003] In the prior art, formwork needs to be arranged when pouring concrete beams and columns at building deformation joints. However, currently, the formwork for concrete beams and columns mostly uses tie bolts for fixation. The use of tie bolts requires drilling holes in the wall, and the formwork cannot be adaptively adjusted according to the construction requirements of the deformation joint, with poor adaptability. At the same time, when installing the formwork, it is difficult to ensure the parallel state between formworks. For this reason, we propose a support positioning device for concrete beams and columns at building deformation joints. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a support positioning device for concrete beams and columns at building deformation joints.

[0011] The fixing component includes a fixing plate, an outer fitting plate and a screwing rod. Fixing plates are symmetrically fixed on both sides of the lower end face of the top plate. A screwing rod is installed inside the fixing plate. An outer fitting plate is fixed at one end of the screwing rod close to the first template, and an outer fitting plate is fixed at one end of the screwing rod close to the second template;

[0012] The telescopic component includes a fixing nut, a threaded rod, a first support rod, a first movable plate, an intermediate plate, a horizontal strip plate, a first inner fitting plate, a first connecting seat, a second movable plate, a second inner fitting plate, a second connecting seat and a second support rod. A through hole is provided inside the top plate. A threaded rod is installed inside the through hole. A fixing nut is installed at the connection between the threaded rod and the upper end of the top plate. A horizontal strip plate is installed on the lower side of the threaded rod and below the top plate. An intermediate plate is installed at the lower end of the threaded rod on the lower side of the horizontal strip plate. One end of the intermediate plate is movably connected to a first movable plate, and the other end of the intermediate plate is movably connected to a second movable plate. One end of the first movable plate away from the intermediate plate is movably connected to a first inner fitting plate through a first connecting seat. One end of the second movable plate away from the intermediate plate is movably connected to a second inner fitting plate through a second connecting seat. A first support rod is connected between the horizontal strip plate and the first movable plate, and a second support rod is connected between the horizontal strip plate and the second movable plate.

[0013] Further, the vertical guide groove is matched with the guide slider, and an axis member is installed at the intersection of the cross bar;

[0014] A fixing member is installed at the intersection of the cross bar.

[0015] Further, the screwing rod is a threaded screw rod, and a threaded hole is provided inside the fixing plate, and the threaded hole is meshed with the screwing rod.

[0016] Further, a horizontal strip groove is provided inside the horizontal strip plate. Sliding rods are installed at one ends of the first support rod and the second support rod close to the horizontal strip plate, and the sliding rods are matched with the horizontal strip groove.

[0017] Further, one end of the first support rod is movably connected to the upper end surface of the first movable plate through a connecting rod, and the other end of the first support rod is inserted into the horizontal strip groove through a sliding rod. One end of the second support rod is movably connected to the upper end surface of the second movable plate through a connecting rod, and the other end of the second support rod is inserted into the horizontal strip groove through a sliding rod.

[0018] Further, circular holes are formed inside the horizontal strip plate, and the circular holes are in clearance fit with the threaded rod. Limiting rings are symmetrically arranged at the upper and lower joints of the circular holes and the threaded rod.

[0019] Further, the upper end surface of the first movable plate and the upper end surface of the horizontal strip plate are in the same plane, and the upper end surface of the second movable plate and the upper end surface of the horizontal strip plate are in the same plane;

[0020] A scale is arranged on the upper end surface of the horizontal strip plate.

[0021] Further, the working steps of the device are specifically as follows:

[0022] Step 1, according to the construction requirements of the deformation joint, slide the guide sliders at both ends of the cross bar along the vertical guide groove to between the first template and the second template. The cross bar continuously unfolds to adjust the distance between the first template and the second template until it meets the size requirements of the deformation joint. Then tighten the shaft center part to fix the cross bar, and the support positioning device is initially formed;

[0023] Step 2, place the initially formed support positioning at the designated position. Since the first movable plate and the second movable plate are respectively movably connected to the middle plate, and the first movable plate is movably connected with a first inner fitting plate through a first connecting seat, and the second movable plate is movably connected with a second inner fitting plate through a second connecting seat. The staff places the telescopic assembly as a whole between the first template and the second template, and then continuously extends and adjusts the first movable plate, the middle plate and the second movable plate. At this time, the middle plate rotates around the threaded rod until the first inner fitting plate is in contact with the inner side surface of the first template, and the second inner fitting plate is in contact with the inner side surface of the second template;

[0024] Step 3, the staff connects the first support rod between the first movable plate and the horizontal strip plate, and connects the second support rod between the second movable plate and the horizontal strip plate. One end of the first support rod is connected to the first movable plate through a connecting rod, and one end of the second support rod is connected to the second movable plate through a connecting rod. The other ends of the first support rod and the second support rod are both inserted into the horizontal strip groove of the horizontal strip plate through sliding rods. A scale is arranged on the upper end surface of the horizontal strip plate. After the two groups of sliding rods slide the same distance along the horizontal strip groove in opposite directions, the first inner fitting plate and the second inner fitting plate are respectively attached to the inner side surfaces of the first template and the second template;

[0025] Step 4: After fixation, the upper end of the threaded rod passes through the top plate through the through hole and is fixed by a fixing nut. Then, turn the screwing rod in the fixing plate. While the screwing rod rotates, the two outer fitting plates continuously approach the outer sides of the first template and the second template until the two outer fitting plates are in contact with the outer sides of the first template and the second template. The top plate is fixed on the upper sides of the first template and the second template, so that the telescopic assembly is centrally arranged between the first template and the second template. After the first template and the second template are arranged, the construction workers can pour the first beam-column and the second beam-column.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. Through the sliding fit of the guiding slider and the vertical guiding groove, the present invention arranges the cross bar between the first template and the second template and adjusts the cross bar according to the construction requirements of the deformation joint. Thus, the distance between the first template and the second template adapts to different deformation joints that meet the size requirements, and the cross bar is fixed by the central axis member. The cross bar and the central axis member provide a stable supporting force for the concrete beam-column at the deformation joint and adapt to different size requirements.

[0028] 2. The movable connection of the first movable plate, the second movable plate, the middle plate, the first inner fitting plate and the second inner fitting plate of the present invention enables the first inner fitting plate and the second inner fitting plate to be attached to the inner sides of the templates. Then, the two ends are respectively connected by the first support rod and the second support rod. One ends of the first support rod and the second support rod slide towards each other and equidistantly along the horizontal strip groove through the sliding rod, so that the first inner fitting plate and the second inner fitting plate are symmetrically attached to the inner sides of the first template and the second template, realizing the support and positioning of the concrete beam-column at the deformation joint; through the combined use of the fixing nut, the screwing rod and the outer fitting plate, the two outer fitting plates are in contact with the outer sides of the first template and the second template, and the top plate is fixed on the upper sides of the first template and the second template. This not only ensures that the telescopic assembly is centrally arranged between the first template and the second template and ensures that the first template and the second template are in a parallel state, but also increases the overall strength of the first template and the second template, providing a stable supporting force for the concrete beam-column at the deformation joint.

[0045] Based on another concept of the same invention, a concrete beam-column support positioning device at a building deformation joint, the working steps of the device are specifically as follows:

[0046] Step 1, according to the construction requirements of the deformation joint, slide the guide sliders 24 at both ends of the cross bar 25 along the vertical guide groove 8 to between the first template 2 and the second template 3. The cross bar 25 is continuously unfolded to adjust the distance between the first template 2 and the second template 3 until it meets the size requirements of the deformation joint. Then, tighten the central member to fix the cross bar 25, and the support positioning device is initially formed;

[0047] Step 2, place the initially formed support positioning on the designated position. Since the first movable plate 12 and the second movable plate 19 are respectively movably connected to the middle plate 14, and the first movable plate 12 is movably connected to a first inner fitting plate 17 through a first connecting seat 171, and the second movable plate 19 is movably connected to a second inner fitting plate 20 through a second connecting seat 201. The staff places the telescopic assembly as a whole between the first template 2 and the second template 3, and then continuously extends and adjusts the first movable plate 12, the middle plate 14 and the second movable plate 19. At this time, the middle plate 14 rotates around the threaded rod 10 until the first inner fitting plate 17 fits against the inner side surface of the first template 2, and the second inner fitting plate 20 fits against the inner side surface of the second template 3;

[0048] Step 3: The staff connect the first support rod 11 between the first movable plate 12 and the horizontal strip plate 15, and connect the second support rod 21 between the second movable plate 19 and the horizontal strip plate 15.

[0049] Step 4: After fixation, the upper end of the threaded rod 10 passes through the top plate 6 through the through hole and is fixed by a fixing nut 9. Then, turn the screwing rod 16 in the fixing plate 7. While the screwing rod 16 rotates, the two groups of outer fitting plates 13 are continuously moved closer to the outer sides of the first template 2 and the second template 3 until the two groups of outer fitting plates 13 are attached to the outer sides of the first template 2 and the second template 3. The top plate 6 is fixed on the upper sides of the first template 2 and the second template 3, so that the telescopic assembly is centered and arranged between the first template 2 and the second template 3.

Then, tighten the central member to fix the cross bar 25, and the support positioning device is initially formed. The setting of the cross bar 25 and the central member provides a stable support force for the concrete beam-column at the deformation joint;

[0051] Place the initially formed support positioning on the designated position.

The first template 2 and the second template 3 are kept in a parallel state. The settings of the first inner fitting plate 17 and the second inner fitting plate 20 realize the support and positioning of the concrete beam and column at the deformation joint;

[0053] After the fixation is completed, the upper end of the threaded rod 10 passes through the top plate 6 through the through hole and is fixed by the fixing nut 9. Then, the screwing rod 16 in the fixing plate 7 is rotated. While the screwing rod 16 rotates, the two groups of outer fitting plates 13 are continuously moved closer to the outer sides of the first template 2 and the second template 3 until the two groups of outer fitting plates 13 are attached to the outer sides of the first template 2 and the second template 3.

The positioning device for concrete beam-column supports at building deformation joints according to claim 1, characterized in that, The upper end surface of the first movable plate (12) and the upper end surface of the horizontal strip plate (15) are in the same plane. The upper end surface of the second movable plate (19) and the upper end surface of the horizontal strip plate (15) are in the same plane; A scale is arranged on the upper end surface of the horizontal strip plate (15).

8. A positioning device for concrete beam-column supports at building deformation joints according to claim 1, characterized in that The working steps of the device are specifically as follows: Step 1, according to the construction requirements of the deformation joint, slide the guide sliders (24) at both ends of the cross rod (25) along the vertical guide groove (8) between the first template (2) and the second template (3). The cross rod (25) is continuously unfolded to adjust the distance between the first template (2) and the second template (3) until it meets the size requirements of the deformation joint. Then, tighten the central member to fix the cross rod (25), and the support positioning device is initially formed; Step 2, place the initially formed support positioning at the designated position. Since the first movable plate (12) and the second movable plate (19) are respectively movably connected to the middle plate (14), and the first movable plate (12) is movably connected with a first inner fitting plate (17) through a first connecting seat (171), and the second movable plate (19) is movably connected with a second inner fitting plate (20) through a second connecting seat (201). The staff places the telescopic assembly as a whole between the first template (2) and the second template (3), and then continuously extends and adjusts the first movable plate (12), the middle plate (14) and the second movable plate (19). At this time, the middle plate (14) rotates around the threaded rod (10) until the first inner fitting plate (17) is in contact with the inner side surface of the first template (2), and the second inner fitting plate (20) is in contact with the inner side surface of the second template (3); Step 3: The staff connect the first strut (11) between the first movable plate (12) and the horizontal strip plate (15), and connect the second strut (21) between the second movable plate (19) and the horizontal strip plate (15). One end of the first strut (11) is connected to the first movable plate (12) through a connecting rod (18), and one end of the second strut (21) is connected to the second movable plate (19) through a connecting rod (18). The other ends of the first strut (11) and the second strut (21) are both inserted into the horizontal strip groove (22) of the horizontal strip plate (15) through a sliding rod (23). A scale is provided on the upper end face of the horizontal strip plate (15). After the two groups of sliding rods (23) slide towards each other the same distance along the horizontal strip groove (22), the first inner fitting plate (17) and the second inner fitting plate (20) are respectively attached to the inner sides of the first template (2) and the second template (3). Step 4: After fixation, the upper end of the threaded rod (10) passes through the top plate (6) through the through hole and is fixed by a fixing nut (9). Then, rotate the screwing rod (16) in the fixing plate (7). While the screwing rod (16) rotates, the two groups of outer fitting plates (13) continuously approach the outer sides of the first template (2) and the second template (3) until the two groups of outer fitting plates (13) are attached to the outer sides of the first template (2) and the second template (3). The top plate (6) is fixed on the upper sides of the first template (2) and the second template (3), so that the telescopic assembly is centered and arranged between the first template (2) and the second template (3). After the first template (2) and the second template (3) are arranged, the construction workers can pour the first beam-column (1) and the second beam-column (5).
