Description

Technical Field

[0001] This utility model belongs to the technical field of building structural column construction, specifically a jointing device for one-time forming of structural columns. Background Technology

[0002] In the construction of structural columns, there is an increasing number of projects utilizing the advantages of aluminum formwork to transform the original secondary brickwork into cast-in-place concrete infill wall construction. This method allows for the integral casting and one-time molding of the structural column. However, the following problems still exist in actual construction:

[0003] 1. The connection between the structural column and the main structure has poor seismic resistance and is prone to cracking, which affects the overall strength of the building and also increases the cost of later repairs.

[0004] 2. The reinforcing bars at the connection between the structural column and the main structure are prone to detach from the concrete, which cannot ensure the tightness of the connection between the structural column and the main structure, nor can it guarantee the load-bearing capacity of the wall.

[0005] Therefore, how to effectively solve the problem of poor connection strength and inability to guarantee the tightness of the connection between the structural column and the main structure is an urgent technical problem to be solved. Utility Model Content

[0006] To address the shortcomings in the aforementioned background technology, this utility model proposes a jointing device for one-time forming of structural columns, which solves the problems of poor connection strength and inability to guarantee the tightness of the connection between the structural column and the main structure.

[0007] The technical solution of this application is as follows:

[0008] A jointing device for one-time forming of structural columns includes a jointing plate inserted into the reinforcing bars of the structural column. The jointing plate has a material transfer port for pouring concrete in the middle. The jointing plate serves as both a temporary formwork and a permanent interface isolation layer, thereby improving construction efficiency and accelerating construction progress.

[0009] Furthermore, a second joint plate is attached to the upper surface of the first joint plate, and holes for the reinforcing bars of the structural column are provided around the second joint plate. A second material transfer port for pouring concrete is provided in the middle of the second joint plate.

[0010] Furthermore, the second material inlet is equipped with an openable and closable elastic blade. When the concrete is poured to the second joint plate, the elastic blade can cover the upper surface of the concrete to achieve one-time forming of the structural column. The first joint plate and the second joint plate form a flexible buffer layer between the structural column and the wall, preventing cracks from being directly transmitted to the wall. It serves as both a temporary formwork and a permanent interface isolation layer, improving construction efficiency and accelerating the construction progress.

[0011] Furthermore, one end of the elastic blade is connected to the second material inlet, while the other end of the elastic blade is suspended in the air.

[0012] Furthermore, two elastic blades are symmetrically arranged, and the elastic blades are fixedly connected to both sides of the second material transfer port. The inner ends of the elastic blades are in a suspended state without being connected. When concrete is poured, the concrete flows down from the gap between the two elastic blades. When the concrete fills the second material transfer port, the elastic blades cover the upper surface of the concrete, which serves as a barrier and can realize the one-time molding of the structural column.

[0013] Furthermore, several steel bar slots are provided at intervals around the perimeter of the joint plate.

[0014] Furthermore, the spacing between the rebar slots and adjacent rebar slots, and the spacing between the holes and adjacent holes are the same, ensuring that the holes and rebar slots are concentrically set, allowing the structural column rebars to freely pass into the holes.

[0015] Furthermore, the joint plate is connected to the structural column template by a fastener, which can be an iron nail. The structural column template and the joint plate are nailed together by the iron nail to fix the position of the joint plate.

[0016] Furthermore, the joint panel is made of extruded polystyrene foam board, which is relatively inexpensive and easy to process into appropriate sizes, and can effectively serve as a joint separator.

[0017] Furthermore, the second joint plate is a polytetrafluoroethylene (PTFE) plate. The PTFE plate has sufficient strength and rigidity to meet the function of internal support for the template, and has the properties of corrosion resistance and high durability.

[0018] The specific beneficial effects of this utility model include:

[0019] 1. The joint board serves as both a temporary formwork and a permanent interface isolation layer, improving construction efficiency and accelerating construction progress;

[0020] 2. Once the concrete is poured to the second joint plate, the upper surface of the concrete can be covered by the elastic blades to achieve one-time forming of the structural column. The first joint plate and the second joint plate form a flexible buffer layer between the structural column and the wall to prevent cracks from being directly transmitted to the wall.

[0021] 3. After the joint plate is fixed to the formwork of the structural column, concrete can be poured directly, eliminating the need for formwork removal. The masonry wall and the structural column can be constructed simultaneously, greatly shortening the construction period. At the same time, it can also ensure the connection strength between the steel bars and the wall at the joint, ensuring the overall connection strength, effectively avoiding possible cracking later, and ensuring the load-bearing capacity of the wall.

[0022] 4. The elastic blades of the second material inlet can be opened and closed. They automatically unfold during pouring to allow concrete to pass through, and close after completion to prevent backflow or leakage, ensuring the density of the concrete. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] A jointing device for one-time forming of structural columns includes a jointing plate 1 inserted into the reinforcing steel bar 3 of the structural column. The jointing plate 1 has a material transfer port 12 for pouring concrete in the middle. The jointing plate 1 serves as both a temporary formwork and a permanent interface isolation layer, improving construction efficiency and accelerating construction progress. After the jointing plate 1 is fixed to the structural column formwork, concrete can be poured directly, eliminating the need for formwork removal. The masonry wall and structural column can be constructed simultaneously, greatly shortening the construction period. At the same time, it can also ensure the connection strength between the reinforcing steel bar and the wall at the joint, ensuring the overall connection strength, effectively avoiding possible cracking later, and ensuring the load-bearing capacity of the wall.

[0038] Based on the above embodiments, as a preferred embodiment, the upper surface of the joint plate 1 is attached to the joint plate 2. The joint plate 1 and the joint plate 2 are arranged overlappingly but not fixedly connected. The joint plate 2 has holes 21 around its perimeter for the structural column steel bars 3 to pass through, and the middle of the joint plate 2 has a material transfer port 22 for pouring concrete.

[0039] Based on the above embodiments, as a preferred embodiment, the second material inlet 22 is equipped with an openable and closable elastic blade 23. During pouring, the blade automatically unfolds to allow concrete to pass through, and closes after pouring to prevent backflow or leakage, ensuring the density of the concrete. Once the concrete has been poured to the joint plate 2, the elastic blade 23 can cover the upper surface of the concrete to achieve one-time forming of the structural column. The joint plate 1 and joint plate 2 form a flexible buffer layer between the structural column and the wall, preventing cracks from directly transmitting to the wall. This serves both as a temporary formwork and as a permanent interface isolation layer, improving construction efficiency and accelerating the construction progress.

[0040] Based on the above embodiments, as a preferred embodiment, the joint plate 1 is made of extruded polystyrene foam board. Extruded polystyrene foam board is relatively inexpensive and easy to process into appropriate sizes, and can effectively serve as a separation joint. Several steel bar slots 11 are provided at intervals around the joint plate 1, so that each structural column steel bar 3 can be stuck in the steel bar slot 11.

[0041] Based on the above embodiments, as a preferred embodiment, the joint plate 2 is a polytetrafluoroethylene (PTFE) plate. The PTFE plate has sufficient strength and rigidity to meet the function of internal support of the template and has the properties of corrosion resistance and high durability.

[0042] Based on the above embodiments, as a preferred embodiment, the interval between the rebar slot 11 and the adjacent rebar slot 11 and the interval between the hole 21 and the adjacent hole 21 are the same, and the hole 21 and the rebar slot 11 are concentrically arranged, so that the structural column rebar 3 can freely pass into the hole 21.

[0043] Based on the above embodiments, as a preferred embodiment, the joint plate 1 is connected to the structural column template 4 via a fastener 5. The fastener can be a nail, which is used to nail the structural column template 4 and the joint plate 1 together to fix the position of the joint plate 1.

[0044] Specifically, a number of tie plates 1 are arranged at intervals along the length of the reinforcing bar 3 of the structural column. Preferably, a tie plate 1 can be arranged at the top, middle and bottom of the structural column, and a tie plate 2 is attached to each tie plate 1.

[0045] Specifically, such as Figure 1 As shown, structural columns are placed at the corners where walls meet, or as... Figure 6 As shown, structural columns are placed in the gaps between walls.

[0046] Based on the above implementation method, as a preferred implementation method, one end of the elastic blade 23 is connected to the material conveying port 22, and the other end of the elastic blade 23 is suspended.

[0047] Preferably, such as Figure 4 As shown, two elastic blades 23 are symmetrically arranged, and the elastic blades 23 are fixedly connected to both sides of the material transfer port 22. The inner ends of the elastic blades 23 are in a suspended state without being connected. When concrete is poured, the concrete flows down from the gap between the two elastic blades 23. When the concrete fills the material transfer port 22, the elastic blades 23 cover the upper surface of the concrete, which plays a role in blocking, and the structural column can be formed in one step.

[0048] Based on the above embodiments, as a preferred embodiment, the inner wall of the rebar slot 11 is arc-shaped, which fits more closely with the outer wall of the rebar.

[0049] Based on the above embodiments, as a preferred embodiment, the inner wall of the rebar slot 11 is provided with an anti-slip component. Specifically, the anti-slip component is an anti-slip pad, such as a rubber pad, provided inside the rebar slot 11; or, the anti-slip component is an anti-slip protrusion provided inside the rebar slot 11. The anti-slip protrusion can be dot-shaped protrusions or textured protrusions of any shape. Its function is to increase the contact friction between the rebar slot 11 and the reserved rebar, and to prevent the joint plate 1 from moving. The specific form can refer to the prior art, and is not specifically limited in this embodiment, as long as it can increase friction.

[0050] The construction method of this utility model is as follows:

[0051] Tie the structural column reinforcement 3; place the joint plate 1 at the beam-column junction of the structural column and fix it with iron nails to the structural column formwork 4, and clamp the multiple structural column reinforcement 3 into the slot 11 one by one; insert the multiple structural column reinforcement 3 into the hole 21 of the joint plate 2 and place it on the joint plate 1; pour concrete until the material inlet 22 is filled and the elastic blade 23 is closed.
