Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a positioning device for pre-embedded steel bars of a grid. Background Art

[0002] The pre-embedded steel bars of the grid are a common structure strengthening method in civil engineering. The existing pre-embedded steel bars of the grid are usually pre-positioned during construction and installation; the positioning method usually uses the method of punching holes in a steel plate to ensure the accurate position of the pre-embedded steel bars in the grid structure;

[0003] The specific implementation method of the above method is as follows: holes matching the diameter of the pre-embedded steel bars are pre-processed on the steel plate, and then the steel plate and the pre-embedded steel bars are firmly connected together by welding, bolt connection or other fixing methods to assist in positioning the pre-embedded steel bars. Although this positioning method has a relatively simple structure, since only a steel plate is used for positioning, that is, each steel bar is positioned in the form of single-hole positioning, there is still a risk of inclination and deviation after the steel bar passes through the hole. Summary of the Utility Model

[0004] A positioning device for pre-embedded steel bars of a grid according to the utility model is used to solve the defect that there is a risk of inclination and eccentric tension in the pre-embedded steel bars of the grid in the prior art, and to realize the accurate installation and positioning of the pre-embedded steel bars of the grid.

[0007] A plurality of insertion holes are formed in each horizontal support frame, and the axes of the insertion holes on each horizontal support frame are collinear with the axes of the insertion holes on the adjacent horizontal support frames in a one-to-one correspondence.

[0008] According to the positioning device for pre-embedded steel bars of the utility model, during use, the steel bars are inserted into the corresponding insertion holes from top to bottom.

[0016] In some embodiments of the present utility model, a support device is further included. A support device is arranged on each vertical bar, and the support device is used to support the vertical bar.

[0017] By adopting the above embodiments, the setting of the support device supports the vertical bar, and further supports the device to ensure the stability of the device during use.

[0018] In some embodiments of the present utility model, each support device includes a connecting piece and a support rod.

[0039] The following will describe the exemplary embodiments of the present disclosure in more detail with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0040] It should be understood that the terms used herein are for the purpose of describing particular example embodiments only and are not intended to be limiting. Unless the context clearly dictates otherwise, the singular forms "a", "an", and "the" as used herein may also include the plural forms. The terms "comprises", "comprising", "includes", and "including" are inclusive and thus specify the presence of stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the particular order described or illustrated, unless an execution order is expressly stated. It should also be understood that additional or alternative steps may be used.

[0041] Although the terms first, second, third, etc. may be used herein to describe multiple elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or section from another. Unless the context clearly dictates otherwise, terms such as "first", "second", and other numerical terms when used herein do not imply an order or sequence. Thus, the first element, component, region, layer, or section discussed below may be referred to as the second element, component, region, layer, or section without departing from the teachings of the example embodiments.

[0042] For ease of description, spatial relative relationship terms may be used herein to describe the relationship of one element or feature to another element or feature as shown in the figures, such as "inner", "outer", "inside", "outside", "below", "beneath", "above", "over", etc. Such spatial relative relationship terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is flipped, an element described as "below" or "beneath" another element or feature will then be oriented "above" or "over" the other element or feature. Thus, the example term "below" can include both an upper and a lower orientation. The device may be otherwise oriented, rotated 90 degrees or in other directions, and the spatial relative relationship descriptors used herein are to be interpreted accordingly.

[0043] Existing embedded steel bars of three - limb grids are usually positioned by the method of punching holes in steel plates. The specific implementation method is to pre - process holes on the steel plate that match the diameter of the embedded steel bars, and then use welding, bolt connection or other fixing methods to firmly connect the steel plate and the embedded steel bars together to assist in positioning the embedded steel bars. Although this positioning method has a relatively simple structure, since it only uses a single steel plate for positioning, that is, each steel bar is positioned in a single - hole positioning form, there is still a risk of inclination and deviation after the steel bar passes through the hole. If you want to avoid this risk, you need to use very thick steel plates, which will be extremely wasteful of materials and the steel plates will be very heavy, making processing, installation and handling more difficult. At the same time, it is very difficult to reuse the steel plate after it is connected to the embedded steel bar. Each construction requires a newly opened positioning steel plate, which is time - consuming, laborious and the processing is rather cumbersome.

[0044] The following combines Figures 1 to 5 to describe a positioning device for the embedded steel bars of a grid of the present utility model.

[0045] As Figures 1 to 5 shown, according to an embodiment of the first aspect of the present utility model, a positioning device for the embedded steel bars of a grid is proposed, which includes a vertical support assembly and at least two horizontal support frames. At least two horizontal support frames are arranged at intervals from top to bottom on the vertical support assembly;

[0046] Each horizontal support frame is a polygonal structure;

[0047] A plurality of insertion holes 21 are opened on each horizontal support frame, and the axes of the insertion holes 21 on each horizontal support frame are collinear with the axes of the insertion holes 21 on the adjacent horizontal support frame in one - to - one correspondence.

[0048] In the above - mentioned embodiment, it should be noted that the shape formed by connecting the plurality of insertion holes 21 in sequence is a polygonal structure.

[0049] The technical effects achieved by the above - mentioned embodiment are as follows:

[0050] First, by arranging at least two horizontal support frames at intervals from top to bottom on the vertical support assembly and matching the axes of the insertion holes 21 on each horizontal support frame to be collinear with the axes of the insertion holes 21 on the adjacent horizontal support frame in one - to - one correspondence, it is realized that after the steel bar is inserted into the insertion hole 21, it is positioned by at least two points up and down, so as to ensure the accurate position of the embedded steel bar in the grid structure while ensuring that the steel bar remains vertical from top to bottom, and avoid the risk of inclination and eccentric tension of the steel bar.

[0051] Second, after the steel bars are pre-embedded, the installation of the remaining steel bars and the pre-embedded steel bars can continue. Since the steel bars are pre-embedded after being inserted into the corresponding insertion holes 21 and have no direct connection with this device, this device can be reused.

[0052] Third, according to requirements, the corresponding number of insertion holes 21 are opened on the transverse support frame of this device. For example, if it is necessary to pre-embed three-limb grid steel bars, only the insertion holes 21 arranged in a triangle need to be opened adaptively for pre-embedding and positioning of the three-limb grid steel bars; if it is necessary to pre-embed four-limb grid steel bars, only the insertion holes 21 arranged in a quadrilateral need to be opened adaptively for pre-embedding and positioning of the four-limb grid steel bars; if it is necessary to pre-embed more types of grid steel bars, only the corresponding insertion holes 21 need to be opened on the transverse support frame, which is very convenient.

[0053] Optionally, as Figure 1 and Figure 2 shown, each transverse support frame includes a plurality of cross bars 1, and the plurality of cross bars 1 are connected in sequence from head to tail. The side of each cross bar 1 is connected to the vertical support assembly, and at least one insertion hole 21 is opened on each cross bar 1.

[0054] In the above optional embodiment, it should be noted that the plurality of cross bars 1 are connected in sequence from head to tail by welding or screwing.

[0055] The beneficial effect of the above optional embodiment is that the polygonal transverse support frame formed by splicing the cross bars 1 makes the middle of the transverse support frame in a hollow state, providing more operating space for steel bar pre-embedding and the fixing, disassembly and assembly of this device, and indirectly increasing the convenience of steel bar pre-embedding.

[0056] Optionally, as Figure 1 and Figure 2 shown, each transverse support frame includes a cross bar 1 and an insertion block 2. The side of each cross bar 1 is connected to the vertical support assembly. The plurality of cross bars 1 are connected in sequence from head to tail, and each adjacent two cross bars 1 are connected by an insertion block 2. An insertion hole 21 is opened on each insertion block 2, and the insertion block 2 is a polygonal prism structure.

[0057] In the above optional embodiment, it should be noted that the insertion block 2 is welded to the adjacent cross bar 1 through the side; the number of edges of the insertion block 2 is adaptively adjusted according to the number of sides of the support frame of the polygonal structure formed by the combination of the plurality of cross bars 1;

[0058] If the support frame of the polygonal structure formed by the combination of the plurality of cross bars 1 is an equilateral triangle, then the insertion block 2 adopts a regular triangular prism or a regular hexagonal prism;

[0059] If the support frame of the polygonal structure formed by the combination of multiple cross bars 1 is a quadrilateral, then the insertion holes 2 are in the shape of a quadrangular prism, and so on;

[0060] The number of cross bars 1 is determined according to the type of the embedded steel bars of the grille. For example, if the embedded steel bars of the grille to be carried out are three-leg grille embedded steel bars, then each horizontal support frame only needs three cross bars 1 to cooperate with three insertion blocks 2 to be sequentially spliced to form a triangular structure; if the embedded steel bars of the grille to be carried out are four-leg grille embedded steel bars, then each horizontal support frame only needs four cross bars 1 to cooperate with four insertion blocks 2 to be sequentially spliced to form a quadrilateral structure.

[0061] The connection mode between the side surface of each cross bar 1 and the vertical support assembly is welding connection, clamping connection, screwing connection or other connection methods.

[0062] The beneficial effects of the above optional embodiments are as follows: The setting of the insertion blocks 2 increases the convenience of connection between the respective cross bars 1 of the insertion blocks and the stability after connection, and provides more convenient adjustment for the opening of the insertion holes 21.

[0063] Optionally, as Figure 1 and Figure 2 shown, the vertical support assembly includes a plurality of parallel vertical rods 3. Two horizontal support frames are both arranged at intervals from top to bottom between the plurality of vertical rods 3, and each cross bar 1 of each horizontal support frame is connected to at least one vertical rod 3.

[0064] In the above optional embodiment, it should be noted that each vertical rod 3 is perpendicular to the corresponding cross bar 1.

[0065] The beneficial effects of the above optional embodiments are as follows: The spaced arrangement of the plurality of vertical rods 1 in cooperation with the spaced arrangement of the horizontal support frames realizes the state that the device is hollow both horizontally and vertically, further increases the operation space of the construction personnel, and further ensures the convenience of bundling the embedded steel bars with other steel bars and the like.

[0066] Optionally, as Figure 1 、 Figure 3 、 Figure 4 and Figure 5 shown, it further includes a support device 4. A support device 4 is arranged on each vertical rod 3, and the support device 4 is used to support the vertical rod 3;

[0067] Each support device 4 includes a connecting piece 41 and a support rod 42. The connecting piece 41 is installed on the corresponding vertical rod 3, and one end of the support rod 42 is rotatably connected to the connecting piece 41. During operation, the other end of the support rod 42 shown supports on the ground or the wall surface;

[0068] The connecting member 41 includes a connecting block 412 and a limiting block 413. The connecting block 412 is installed on the corresponding vertical rod 3. A limiting block 413 is provided on the connecting block 412. The support rod 42 is rotatably connected to the connecting block 412. During operation, the side surface of the support rod 42 abuts against the limiting block 413.

[0069] The connecting member 41 further includes a sleeve 411. The sleeve 411 is sleeved on the corresponding vertical rod 3. The connecting block 412 is connected to the vertical rod 3 through the sleeve 411.

[0070] In the above optional embodiment, it should be noted that the sleeve 411 and the corresponding vertical rod 3 are connected by means of screwing or welding. A sleeve 411 is connected to each vertical rod 3. At least one connecting block 412 is provided on the side wall of each sleeve 411. When the number of connecting blocks 412 is at least two, at least two connecting blocks 412 are arranged at intervals on the side wall of the sleeve 411. The connecting block 412 and the sleeve 411 are connected by means of screwing or welding. Each connecting block 412 is rotatably connected to a support rod 42 correspondingly. The support rod 42 and the connecting block 412 are rotated through a rotating shaft.

[0071] The beneficial effect of the above optional embodiment is that: through the rotatable connection between the support rod 42 and the connecting block 412, a right triangle structure is formed by the cooperation of the support rod 42, the ground or wall surface, and the vertical rod 3, and the stability of the triangle is used to support the device. Through the setting of the limiting block 413, the maximum rotation position of the support rod 42 can be effectively limited to prevent the support rod 42 from shaking during use.

[0072] Optionally, as Figure 1 and Figure 2 shown, the number of insertion holes 21 on each transverse support frame is three, and the shape of the three insertion holes 21 connected in sequence is an equilateral triangle.

[0073] The beneficial effect of the above optional embodiment is that: through the setting that the three insertion holes 21 are an equilateral triangle, the pre-embedded of the three-leg grid steel bars can be adapted to the maximum extent.

[0074] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
