Description

Technical Field

[0001] This invention relates to the field of construction tools, specifically to an adjustable connecting device for supporting the main rib of beam bottom formwork and its usage method. Background Technology

[0002] In building construction, the use of disc-lock scaffolding for formwork support of roof beams is becoming increasingly widespread. Disc-lock scaffolding is a new type of building support system, composed of uprights, horizontal bars, and diagonal braces. It is multifunctional, can be assembled in different forms to meet various construction needs, has a simple structure, is easy to assemble and disassemble, uses self-locking pin connections, is safe and reliable, and has a large load-bearing capacity. It is also economical and practical, with quick assembly reducing costs, a neat appearance, and good rust prevention due to hot-dip galvanizing. When using it, it is necessary to strictly follow the installation plan, inspect the components, set up safety precautions, and conduct regular inspections and maintenance. Due to its many advantages, it is widely used in building construction, providing stable and efficient support for engineering projects.

[0003] Currently, the spacing between the discs on the uprights of the disc-lock scaffolding is a fixed value (generally 500mm), while the beam height is not fixed. This makes it difficult to utilize the horizontal bars of the disc-lock scaffolding for the main beam of the beam bottom formwork. There are two existing traditional methods:

[0004] Traditional Method 1: Steel pipes are used as the main beams and are directly connected to the uprights using fasteners, depending on the height of the concrete main beam. Advantages: flexible, convenient construction, and low cost; Disadvantages: low load-bearing capacity, generally only suitable for smaller concrete main beams, and the uprights are subject to eccentric forces.

[0005] Traditional Method Two: Double or single support beams are fastened to the disc of the disc-locked uprights. The top support is placed on the support beam, and the main beam is placed on the top support. The top support is adjusted according to the different beam heights to achieve beam bottom support. Advantages: Higher load-bearing capacity, which can meet the support of general concrete main beams. Disadvantages: Complex erection, unchanging construction, and relatively wasteful of materials.

[0006] Based on the shortcomings of the existing technology, there is an urgent need to invent an adjustable connecting device for the main support rib of the beam bottom formwork, which is suitable for the main support rib of the beam bottom formwork of the disc-lock support frame. Summary of the Invention

[0007] Based on this, the purpose of the present invention is to provide an adjustable connecting device for the main support rib of the beam bottom formwork and its usage method, so as to solve the technical problems mentioned in the background art.

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

[0009] By adopting the above technical solution, the main support ribs of the bottom formwork of concrete beams with different beam heights can be applied, overcoming the problem that the spacing of the discs on the uprights of the disc-type support frame is fixed while the beam height is not fixed, which greatly improves the flexibility and adaptability of construction.

[0010] Furthermore, the device body includes two sets of trays, with a main rib between the two sets of trays. The trays are designed as L-shaped plates, and the end faces and bottom faces of the main ribs are attached to the outer walls of the main ribs.

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

[0012] Furthermore, the positioning plate is designed as a right-angled triangular plate, and the two sets of mutually perpendicular outer walls of the positioning plate are fixedly connected to the outer wall of the pallet.

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

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

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

[0016] Furthermore, the sleeve is installed at the bottom of the tray, and a through hole is provided at the bottom of the tray to communicate with the sleeve, and the inner diameter of the through hole and the sleeve corresponds to the diameter of the bottom of the top support.

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

[0018] Furthermore, multiple sets of the horizontal pipes are installed on the outer wall of the pallet, and the installation positions of the horizontal pipes are staggered. All sets of the horizontal pipes are connected to the disc-type uprights through steel pipe fasteners. The installation positions of the multiple sets of horizontal pipes are not on the same outer wall of the pallet as the positioning plate and the sleeve.

[0019] By adopting the above technical solutions, the stability of the pallet during subsequent use is effectively improved, while the support effect of the disc-lock uprights on the pallet is further enhanced.

[0020] Furthermore, a support template for supporting the concrete beam is provided at the top of the main beam.

[0021] By adopting the above technical solution, the main beam will work with the pallet to support the support formwork, thereby ensuring the support effect of the support formwork when the concrete beam is poured later.

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

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

[0024] S2: Next, adjust the position of the steel pipe fastener on the horizontal pipe according to the spacing between the two sets of disc-locked columns and the length of the main rib, and then fix the position of the steel pipe fastener on the horizontal pipe.

[0025] S3: Then install the two sets of pallets onto the disc-lock column using the steel pipe fasteners on the horizontal pipe. During installation, the positioning plate is located above the sleeve.

[0026] S4: Adjust the position of the steel pipe fastener on the disc-lock column according to the required beam height of the concrete beam, and then fix the position of the steel pipe fastener on the disc-lock column.

[0027] S5: Finally, install the main rib between the positioning plates on the two sets of pallets, and the pallets support the support template through the main rib.

[0028] When the position of the steel pipe fastener installed on the disc-type column interferes with the position of the disc on the disc-type column, the usage process of this device 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 of the top support according to the beam height;

[0031] S3: Finally, install the main rib onto the top support, and the pallet supports the template through the top support and the main rib.

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

[0033] 1. This invention can be applied to the main support beam of the bottom formwork of concrete beams with different beam heights, overcoming the problem that the spacing of the discs on the uprights of the disc-type support frame is fixed while the beam height is not fixed. It greatly improves the flexibility and adaptability of construction. Whether the installation position of the steel pipe fastener does not interfere with the discs on the disc-type uprights or they interfere with each other, the device has corresponding usage methods to ensure that it can play a role under various construction conditions.

[0034] 2. This invention, by setting up an L-shaped plate-type pallet, can effectively support and restrict the main ribs, ensuring that the main ribs are fixed in position during use. At the same time, the setting of the positioning plate further strengthens the fixation of the main ribs on the pallet, enhancing the safety of the main ribs during use. When the installation position of the steel pipe fastener does not interfere with the disc, multiple sets of horizontal pipes are connected to the disc-type uprights through steel pipe fasteners, improving the stability of the pallet during subsequent use and the support effect of the disc-type uprights 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. The sleeve and the pallet cooperate to support the top support, ensuring the stability of the top support during use and the support effect on the main ribs.

[0035] 3. Compared with the traditional method one, the adjustable connection device of the present invention has a stronger load-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 triangular plate, and the two sets of mutually perpendicular outer walls are fixedly connected to the outer wall of the pallet. While improving the rigidity and load-bearing capacity of the pallet, it also enhances the load-bearing capacity of the entire device.

[0036] 4. The method of using this invention is relatively simple and easy to operate. During the connection process between the steel pipe coupler and the horizontal pipe and the disc-lock column, the position can be adjusted according to the actual situation to meet different construction needs. When it is necessary to support different beam heights, it is only necessary to adjust the position of the steel pipe coupler on the disc-lock column 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 two, the adjustable connection device of this invention reduces material waste to a certain extent. The traditional method two is complicated to set up and requires double or single support beams to be fastened to the disc of the disc buckle upright, and then a top support, etc. In contrast, the device of this invention is more streamlined and efficient while meeting the support requirements.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0045] The embodiments of the present invention will now be described.

[0046] Example 1

[0047] An adjustable connecting device for the main support rib of beam bottom formwork, such as Figure 1 - Figure 5 As shown, the device includes the main body, which mainly includes a tray 1, a positioning plate 2, a horizontal tube 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 sets of trays 1, and a set of main rib 10 is set between the two sets of trays 1. The two sets of trays 1 and the main rib 10 cooperate to support the support template 11, thereby improving the stability of the support template 11 during use. Because the tray 1 is designed as an L-shaped plate, and the end face and bottom face of the main rib 10 are in contact with the outer wall of the main rib 10, the main rib 10 is supported by the tray 1 and also restricted by the tray 1, ensuring the fixation of the position of the main rib 10 during use.

[0049] In this embodiment, a positioning plate 2 for limiting the main rib 10 is installed on the pallet 1. Two sets of positioning plates 2 are symmetrically installed on the outer wall of the pallet 1, and the distance between the two sets of positioning plates 2 corresponds to the width of the main rib 10. When the main rib 10 is installed on the pallet 1, the outer walls on both sides of its end will be in contact with the outer walls of the positioning plates 2, so that the two sets of positioning plates 2 on each set of pallet 1 will limit the end of the main rib 10, thereby further strengthening the fixation of the main rib 10 on the pallet 1 and further enhancing the safety of the main rib 10 during use.

[0050] Because the positioning plate 2 in this embodiment is designed as a right-angled triangular plate, and because the two sets of mutually perpendicular outer walls of the positioning plate 2 are fixedly connected to the outer wall of the pallet 1, the pallet 1 will be 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 pallet 1 are effectively improved, thereby effectively improving the performance of the pallet 1 when in use.

[0051] Meanwhile, in this embodiment, a horizontal pipe 3 is also installed on the outer wall of the pallet 1, and a steel pipe fastener 4 is installed on the horizontal pipe 3. When the pallet 1 is needed, the pallet 1 can be installed on the disc-lock column 7 by connecting the steel pipe fastener 4 on the horizontal pipe 3 to the disc-lock column 7. Before the steel pipe fastener 4 is fixed at the position of the disc-lock column 7, the height of the pallet 1 can be adjusted according to the beam height. This allows the main rib 10 to be connected to different positions of the disc-lock column 7, so that the main rib 10 can be used to support the support formwork 11 of concrete beams 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 from the installation position of the positioning plate 2, to prevent the sleeve 6 and the positioning plate 2 from interfering with each other's normal use, and to ensure that the device can be used smoothly in the future.

[0053] Meanwhile, a through hole 5 is provided at the bottom of the tray 1 to communicate with the sleeve 6, and the inner diameter of the through hole 5 and the sleeve 6 corresponds 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.

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

[0055] For example, multiple sets of horizontal pipes 3 are installed on the outer wall of the pallet 1. The installation positions of the multiple sets of horizontal pipes 3 are staggered, and all sets of horizontal pipes 3 are connected to the disc-type uprights 7 through steel pipe fasteners 4. By setting multiple sets of horizontal pipes 3, the stability of the pallet 1 during subsequent use can be effectively improved, and the support effect of the disc-type uprights 7 on the pallet 1 can be further improved. At the same time, since the installation positions of the multiple sets of horizontal pipes 3 are not on the same outer wall of the pallet 1 as the positioning plate 2 and the sleeve 6, the multiple sets of horizontal pipes 3 will not interfere with each other with the positioning plate 2 and the sleeve 6 during subsequent use.

[0056] Example 2

[0057] A method of using an adjustable connecting device for supporting the main rib of beam bottom formwork, 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, its use process includes the following steps:

[0058] S1: First, install one end of the steel pipe fastener 4 onto the horizontal pipe 3 to initially connect the steel pipe fastener 4 and the horizontal pipe 3. At this time, do not fix the connection between the steel pipe fastener 4 and the horizontal pipe 3.

[0059] S2: Next, adjust the position of the steel pipe fastener 4 on the horizontal pipe 3 according to the spacing between the two sets of disc-type uprights 7 and the length of the main rib 10. After the adjustment is completed, fix the position of the steel pipe fastener 4 on the horizontal pipe 3 to complete the connection and fixation of the steel pipe fastener 4 on the horizontal pipe 3.

[0060] S3: Then, the two sets of pallets 1 are installed onto the disc-lock column 7 through the steel pipe fasteners 4 on the corresponding horizontal pipes 3. After the steel pipe fasteners 4 are installed onto the disc-lock column 7, the connection between the steel pipe fasteners 4 and the disc-lock column 7 is not fixed, so as to facilitate the subsequent adjustment of the position of the steel pipe fasteners 4 on the disc-lock column 7. At this time, the positioning plate 2 is located above the sleeve 6, ensuring that the pallets 1 and the positioning plate 2 are the ones that support the main rib 10 in the future.

[0061] S4: Subsequently, the user can adjust the position of the steel pipe fastener 4 on the disc-lock 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-lock column 7 is fixed so that the positions of the two sets of pallets 1 on the disc-lock column 7 are fixed, thus completing the connection between the pallet 1 and the disc-lock column 7.

[0062] S5: Finally, install the main rib 10 between the positioning plates 2 on the two sets of pallets 1. At this time, the pallet 1 will cooperate with the positioning plates 2 and the disc-lock column 7 to support and restrict the main rib 10, ensuring the stability and fixation of the position of the main rib 10. Then, the support template 11 can be erected on the main rib 10. The pallet 1 will support the support template 11 through the main rib 10, ensuring the support effect of the subsequent support template 11 on the concrete beam 12.

[0063] Example 3

[0064] A method of using an adjustable connecting device for supporting the main rib of beam bottom formwork, such as... Figure 1 , Figure 4 and Figure 5 As shown, the usage method of this embodiment is largely the same as that of Embodiment 2. The difference lies in the following steps 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 interfere with each other:

[0065] S1: Install the pallet 1 in reverse so that the sleeve 6 is above the positioning plate 2. After the pallet 1 is installed and fixed on the disc buckle column 7, the positioning plate 2 will support and further reinforce the pallet 1 to improve the overall load-bearing capacity of the pallet 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 is successfully installed on the tray 1. At this time, the user can adjust 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 top support 9 during subsequent use and its subsequent support effect on the main beam 10.

[0067] S3: Finally, install the main rib 10 onto the top support 9. 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. Then the support template 11 can be erected on the main rib 10. At this time, the tray 1 supports the support template 11 through the top support 9 and the main rib 10, so that even when the steel pipe fastener 4 is interfered with by the disc 8, this connecting device can still be used smoothly and the main rib 10 can still be smoothly connected to the disc-type column 7.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
