Description

Technical Field

[0001] The invention relates to the field of construction tools, in particular to an adjustable connecting device for supporting main ribs of a beam bottom template and a use method thereof. Background Art

[0002] In construction, the use of disc-type support frames for formwork support of beams is becoming more and more common. The disc-type support frame is a new type of building support system, which is composed of vertical poles, horizontal poles, diagonal poles and other components. It is multifunctional and can be composed of different forms to meet various construction needs; it has a simple structure, convenient assembly and disassembly, and adopts self-locking pin connection, which is safe and reliable and has a large bearing capacity. At the same time, it is economical and practical, fast splicing can reduce costs, the appearance is neat, and the hot-dip galvanizing process has good rust prevention. When in use, it is necessary to strictly follow the plan to build, check the components, set up safety protection, and regularly inspect and maintain it. It is widely used in construction due to its many advantages, providing stable and efficient support guarantee for engineering construction.

[0003] At present, the spacing of the discs on the vertical poles of the disc-type support frame is fixed (usually 500mm), while the height of the beam is not fixed, which makes it difficult for the main beam of the bottom formwork to use the horizontal rod of the disc-type support frame. There are two traditional methods:

[0004] Traditional method 1: Steel pipe is used as the main beam, and fasteners are used to connect it directly to the vertical pole according to the height of the concrete main beam. Advantages: flexible, convenient construction, low cost; Disadvantages: small bearing capacity, generally only used for smaller concrete main beams, and the vertical pole is subject to eccentric force;

[0005] Traditional method 2: Double joists or single joists are fastened to the disc of the disc-shaped upright, the top support is set on the joist, and then the main rib is placed on the top support. According to the different beam heights, the top support is adjusted to achieve beam bottom support; Advantages: higher bearing capacity, can meet the general concrete main beam support; Disadvantages: complex erection, unchanged construction, and relatively wasteful of materials.

[0006] Based on the above-mentioned shortcomings of the prior art, it is urgent to invent an adjustable connecting device for supporting the main ribs of the beam bottom template, which is suitable for the main ribs supported by the disc-type support frame beam bottom template. Summary of the invention

[0007] Based on this, the purpose of the present invention is to provide an adjustable connection device for supporting the main ribs of the bottom formwork of the beam and a method of using the same, so as to solve the technical problems mentioned in the above background technology.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an adjustable connecting device for supporting the main ribs of the bottom formwork of the beam, comprising a device body; the device body comprises a tray for supporting the main ribs, a positioning plate for limiting the main ribs is installed on the tray, and a horizontal tube is installed on the outer wall of the tray, a steel tube fastener is installed on the horizontal tube, and the horizontal tube is connected to the disc-type column through the steel tube fastener; a sleeve is installed on the tray for installing a top support.

[0009] By adopting the above technical scheme, the main ribs can be supported by concrete beam bottom formwork applicable to different beam heights, overcoming the problem that the spacing between the discs on the disc-buckle support frame uprights is fixed but the beam height is not fixed, thereby greatly improving the flexibility and adaptability of construction.

[0010] Furthermore, the device body includes two groups of trays, a group of main ribs are arranged between the two groups of trays, the trays are designed as L-shaped plates, and the end faces and bottom faces of the main ribs are both in contact with the outer walls of the main ribs.

[0011] By adopting the above technical solution, under the action of two sets of pallets and main ribs, the stability of the supporting formwork during use is effectively improved.

[0012] Furthermore, the positioning plate is designed as a right-angled triangle plate, and two sets of outer walls of the positioning plate that are perpendicular to each other are fixedly connected to the outer wall of the tray.

[0013] By adopting the above technical solution, under the action of the positioning plate, the rigidity of the pallet itself and its load-bearing capacity are effectively improved.

[0014] Furthermore, two groups of positioning plates are symmetrically installed on the outer wall of the pallet, and the spacing between the two groups of positioning plates corresponds to the width of the main ribs.

[0015] By adopting the above technical solution, the two groups of positioning plates on each group of pallets will restrict the ends of the main ribs, thereby further strengthening the fixation of the main ribs on the pallets.

[0016] Furthermore, the sleeve is installed at the bottom of the tray, and a through hole connected to the sleeve is opened through the bottom of the tray, and the inner diameters of the through hole and the sleeve correspond to the bottom diameter of the top support.

[0017] By adopting the above technical solution, it is ensured that the top support can be smoothly installed on the pallet when needed in the future.

[0018] Furthermore, multiple groups of horizontal tubes are installed on the outer wall of the pallet, and the installation positions of the horizontal tubes are staggered, and the multiple groups of horizontal tubes are connected to the disc-type columns through steel pipe fasteners, and the installation positions of the multiple groups of horizontal tubes are not on the same outer wall of the pallet as the positioning plates and sleeves.

[0019] By adopting the above technical solution, the stability of the pallet during subsequent use is effectively improved, and the supporting effect of the disc-type columns on the pallet is further improved.

[0020] Furthermore, a supporting formwork for supporting the concrete beam is provided on the top of the main rib.

[0021] By adopting the above technical solution, the main ribs will cooperate with the pallet to support the supporting formwork, so as to ensure the supporting effect of the supporting formwork during the subsequent pouring of concrete beams.

[0022] The present invention also provides a method for using an adjustable connecting device for supporting a main rib of a beam bottom template, and the method comprises the following steps:

[0023] S1: Install one end of the steel pipe fastener onto the horizontal pipe;

[0024] S2: Next, the position of the steel pipe fastener on the horizontal pipe is adjusted according to the spacing between the two sets of disc-shaped columns and the length of the main rib, and then the position of the steel pipe fastener on the horizontal pipe is fixed;

[0025] S3: Then install the two sets of trays on the disc-type columns through the steel pipe fasteners on the horizontal pipes. During installation, the positioning plates are located above the sleeves;

[0026] S4: adjusting the position of the steel pipe fastener on the disc-type column according to the required beam height of the concrete beam, and then fixing the position of the steel pipe fastener on the disc-type column;

[0027] S5: Finally, the main ribs are installed between the positioning plates on the two sets of pallets, and the pallets support the supporting templates through the main ribs.

[0028] When the steel pipe fastener is installed at the position of the disc-type column and the position of the disc on the disc-type column interferes with each other, the use process of the device body includes the following steps:

[0029] S1: Install the tray in reverse so that the sleeve is above the positioning plate;

[0030] S2: Insert the bottom of the top support into the sleeve, and then adjust the height of the top support according to the beam height;

[0031] S3: Finally, the main ribs are installed on the top supports, and the pallet supports the supporting formwork through the top supports and the main ribs.

[0032] In summary, the present invention mainly has the following beneficial effects:

[0033] 1. The present invention can be applied to the main ribs of concrete beam bottom formwork support with different beam heights, overcoming the problem that the spacing between the discs on the disc-type support frame uprights is fixed but the beam height is not fixed, greatly improving the flexibility and adaptability of construction. Regardless of whether the installation position of the steel pipe fastener does not interfere with the discs on the disc-type uprights, or interferes with each other, the device has a corresponding method of use to ensure that it can function under various construction conditions.

[0034] 2. The present invention can effectively support and limit the main ribs by providing a pallet with an L-shaped plate, ensuring that the main ribs are fixed in position when in use. At the same time, the provision of the positioning plate further strengthens the fixation of the main ribs on the pallet, and enhances the safety of the main ribs when in use. When the installation position of the steel pipe fastener does not interfere with the disc, multiple groups of horizontal pipes are connected to the disc-type columns through the steel pipe fasteners, thereby improving the stability of the pallet during subsequent use and the supporting effect of the disc-type columns on the pallet. When the installation position of the steel pipe fastener interferes with the disc, the top support is installed in the sleeve on the pallet, and the sleeve and the pallet cooperate to support the top support, thereby ensuring the stability of the top support during use and the supporting effect on the main ribs.

[0035] 3. Compared with the traditional method 1, the adjustable connection device of the present invention has a stronger bearing capacity and can meet the support requirements of concrete main beams of different sizes, rather than being limited to smaller concrete main beams. At the same time, the positioning plate is designed as a right-angled triangle plate, and the two sets of outer walls that are perpendicular to each other are fixedly connected to the outer wall of the pallet, which improves the rigidity and bearing capacity of the pallet while also enhancing the bearing capacity of the entire device.

[0036] 4. The method of use of the present invention is relatively simple and easy to operate. During the connection process between the steel pipe fasteners and the horizontal pipes and the disc-type columns, the position can be adjusted according to the actual situation to meet different construction requirements. When it is necessary to support different beam heights, it is only necessary to adjust the position of the steel pipe fasteners on the disc-type columns or the height of the top support. There is no need to carry out complicated erection work, which improves construction efficiency.

[0037] 5. Compared with the traditional method 2, the adjustable connection device of the present invention reduces the waste of materials to a certain extent. The traditional method 2 is complicated to set up, and requires double support beams or single support beams to be buckled and fixed on the disc of the disc-buckle vertical pole, and then a top support is set, etc. The device of the present invention is more streamlined and efficient while meeting the support requirements.

[0044] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0045] The following describes an embodiment of the present invention based on its overall structure.

[0046] Embodiment 1

[0047] An adjustable connection device for supporting the main ribs of the bottom formwork of the beam, such as Figure 1 - Figure 5 As shown, the device body includes a tray 1, a positioning plate 2, a horizontal pipe 3, a steel pipe fastener 4, a through hole 5 and a sleeve 6;

[0048] The tray 1 is used to support the main rib 10, and each device body includes two groups of trays 1, and a group of main ribs 10 is arranged between the two groups of trays 1. The two groups of trays 1 cooperate with the main ribs 10 to support the support template 11, so as to improve the stability of the support template 11 when in use. Because the tray 1 is designed as an L-shaped plate, and the end surface and bottom surface of the main rib 10 are both in contact with the outer wall of the main rib 10, the main rib 10 is supported by the tray 1 while being restricted by the tray 1, ensuring the fixed position of the main rib 10 when in use;

[0049] In the present embodiment, positioning plates 2 for limiting the main ribs 10 are installed on the pallet 1. Two groups of positioning plates 2 are symmetrically installed on the outer wall of the pallet 1. At the same time, the spacing between the two groups of positioning plates 2 corresponds to the width of the main ribs 10. When the main ribs 10 are installed on the pallet 1, the outer walls on both sides of the ends thereof will be in contact with the outer walls of the positioning plates 2, so that the two groups of positioning plates 2 on each group of pallets 1 will limit the ends of the main ribs 10, thereby further strengthening the fixation of the main ribs 10 on the pallet 1 and further enhancing the safety of the main ribs 10 when in use.

[0050] Because the positioning plate 2 in this embodiment is designed as a right-angled triangle plate, and because the two sets of outer walls of the positioning plate 2 are perpendicular to each other and fixedly connected to the outer wall of the tray 1, the tray 1 is supported by the positioning plate 2 when in use. Under the action of the positioning plate 2, the rigidity and load-bearing capacity of the tray 1 are effectively improved, thereby effectively improving the performance of the tray 1 when in use.

[0051] At the same time, the outer wall of the pallet 1 in this embodiment is also installed with a horizontal tube 3, and the horizontal tube 3 is installed with a steel tube fastener 4. When the pallet 1 is needed, the steel tube fastener 4 on the horizontal tube 3 is connected to the disc-type column 7, so that the pallet 1 can be installed on the disc-type column 7. Before the steel tube fastener 4 is fixed at the position of the disc-type column 7, the height of the pallet 1 can be adjusted according to the beam height, so that the present invention can connect the main rib 10 to different positions of the disc-type column 7, so that the main rib 10 is suitable for supporting the support formwork 11 of the concrete beam 12 with different beam heights.

[0052] In this embodiment, a sleeve 6 is further installed on the tray 1, and the sleeve 6 is installed at the bottom of the tray 1, so that its installation position is staggered with the installation position of the positioning plate 2, so as to prevent the sleeve 6 and the positioning plate 2 from interfering with each other's normal use, thereby ensuring that the device can be used smoothly in the future;

[0053] At the same time, a through hole 5 connected to the sleeve 6 is opened at the bottom of the tray 1, and the inner diameters of the through hole 5 and the sleeve 6 correspond to the bottom diameter of the top support 9. The bottom of the top support 9 is inserted into the through hole 5 through the end opening of the sleeve 6, so that the top support 9 can be installed on the tray 1 through the sleeve 6, ensuring that the top support 9 can be smoothly installed on the tray 1 when needed later.

[0054] In this embodiment, a supporting formwork 11 for supporting a concrete beam 12 is provided on the top of the main rib 10. In subsequent use, the main rib 10 will cooperate with the pallet 1 to support the supporting formwork 11, so as to ensure the supporting effect of the supporting formwork 11 when the concrete beam 12 is subsequently poured.

[0055] Exemplarily, multiple groups of horizontal tubes 3 are installed on the outer wall of the pallet 1, and the installation positions of the multiple groups of horizontal tubes 3 are staggered with each other, and the multiple groups of horizontal tubes 3 are connected to the disc-type columns 7 through steel pipe fasteners 4. By setting up the multiple groups of horizontal tubes 3, the stability of the pallet 1 during subsequent use can be effectively improved, and the supporting effect of the disc-type columns 7 on the pallet 1 can be further improved. At the same time, because the installation positions of the multiple groups of horizontal tubes 3 and the positioning plate 2 and the sleeve 6 are not on the same outer wall of the pallet 1, the multiple groups of horizontal tubes 3 will not interfere with the positioning plate 2 and the sleeve 6 during subsequent use.

[0056] Embodiment 2

[0057] A method for using an adjustable connection device for supporting the main rib of a beam bottom template, such as Figure 1 - Figure 3 As shown, when the position of the steel pipe fastener 4 installed on the disc-type column 7 does not interfere with the position of the disc 8 on the disc-type column 7, the use process includes the following steps:

[0058] S1: First, one end of the steel pipe fastener 4 is installed on the horizontal pipe 3 to preliminarily connect the steel pipe fastener 4 and the horizontal pipe 3. At this time, the connection between the steel pipe fastener 4 and the horizontal pipe 3 is not fixed;

[0059] S2: Next, the position of the steel pipe fastener 4 on the horizontal pipe 3 is adjusted according to the spacing between the two sets of disc-shaped columns 7 and the length of the main rib 10. After the adjustment is completed, the position of the steel pipe fastener 4 on the horizontal pipe 3 is fixed, and the connection and fixation of the steel pipe fastener 4 on the horizontal pipe 3 is completed;

[0060] S3: Then, the two groups of pallets 1 are installed on the disc-type columns 7 through the steel pipe fasteners 4 on the corresponding horizontal tubes 3. After the steel pipe fasteners 4 are installed on the disc-type columns 7, the connection between the steel pipe fasteners 4 and the disc-type columns 7 is not fixed, so that the position of the steel pipe fasteners 4 on the disc-type columns 7 can be adjusted later. At this time, the positioning plate 2 is located above the sleeve 6, ensuring that the pallets 1 and the positioning plate 2 are used to support the main ribs 10 later.

[0061] S4: Then, the user can adjust the position of the steel pipe fastener 4 on the disc-type column 7 according to the required beam height of the concrete beam 12. After the position adjustment is completed, the position of the steel pipe fastener 4 on the disc-type column 7 is fixed, so that the positions of the two sets of trays 1 on the disc-type column 7 are fixed, and the connection between the tray 1 and the disc-type column 7 is completed;

[0062] S5: Finally, the main rib 10 is installed between the positioning plates 2 on the two groups of pallets 1. At this time, the pallet 1 will cooperate with the positioning plates 2 and the disc-type columns 7 to support and restrict the main rib 10, ensuring the stability and fixity of the position of the main rib 10. Then the supporting formwork 11 can be erected on the main rib 10. The pallet 1 will support the supporting formwork 11 through the main rib 10, ensuring the subsequent supporting effect of the supporting formwork 11 on the concrete beam 12.

[0063] Embodiment 3

[0064] A method for using an adjustable connection device for supporting the main rib of a beam bottom template, such as Figure 1 , Figure 4 and Figure 5 As shown, the method of use of this embodiment is similar to that of the second embodiment, except that when the steel pipe fastener 4 is installed at the position of the disc-type column 7 and the position of the disc 8 on the disc-type column 7 interferes with each other, the use process of the device body includes the following steps:

[0065] S1: Install the tray 1 in reverse so that the sleeve 6 is located above the positioning plate 2. After the tray 1 is installed on the disc-type column 7 for fixing, the positioning plate 2 will support and further reinforce the tray 1, thereby improving the overall bearing capacity of the tray 1;

[0066] S2: Next, insert the bottom of the top support 9 into the sleeve 6 so that the bottom of the top support 9 passes through the through hole 5, and the top support 9 is smoothly installed on the tray 1. At this time, the user adjusts the height of the top of the top support 9 according to the beam height. After adjusting to a suitable height, the adjustment of the top support 9 can be stopped. At this time, the sleeve 6 will cooperate with the tray 1 to support the top support 9, ensuring the stability of the subsequent top support 9 during use and its subsequent support effect on the main rib 10;

[0067] S3: Finally, the main rib 10 is installed on the top support 9, and the top support 9 will support the main rib 10. Because the top support 9 is supported by the tray 1, the sleeve 6 and the disc-type column 7, the top support 9 can smoothly support the main rib 10, and then the supporting template 11 can be erected on the main rib 10. At this time, the tray 1 supports the supporting template 11 through the top support 9 and the main rib 10, so that when the steel pipe fastener 4 is interfered by the disc 8, the present connection device can still be used smoothly, and the main rib 10 can still be smoothly connected to the disc-type column 7.

[0068] Although an embodiment of the present invention has been shown and described, this specific embodiment is only an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
