Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a filling and holding device. Background Technology

[0002] When connecting columns and cap beams, reinforcing bars are typically pre-embedded in both. When connection is needed, the reinforcing bars from the cap beam are hoisted into the exposed sleeves of the column. Then, grout is used to encase and secure the reinforcing bars of both the column and cap beam together. However, this method can lead to poor grouting results due to limited space at the connection point, construction errors, or structural deformation, thus affecting the connection strength between the column and cap beam reinforcing bars.

[0003] Therefore, there is an urgent need for a filling and holding device to solve the above problems. Utility Model Content

[0008] A positioning unit is disposed at the connection between the upper filling sleeve and the lower filling sleeve. The positioning unit includes an upper positioning frame and a lower positioning frame. Both the upper positioning frame and the lower positioning frame are provided with positioning grooves that cooperate with the insertion of reinforcing bars. The upper positioning frame is connected to the upper filling sleeve, and the lower positioning frame is connected to the lower filling sleeve.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] like Figures 1 to 4 As shown, this embodiment provides a filling and holding device, including a filling unit 1 and a positioning unit 2. The filling unit 1 includes an upper filling sleeve 11 and a lower filling sleeve 12. The upper filling sleeve 11 is fitted onto the outside of the reinforcing bars of the cap beam, and the lower filling sleeve 12 is fitted onto the outside of the reinforcing bars of the column. The upper filling sleeve 11 and the lower filling sleeve 12 form a filling cavity. The positioning unit 2 is disposed at the connection between the upper filling sleeve 11 and the lower filling sleeve 12. The positioning unit 2 includes an upper positioning frame 21 and a lower positioning frame 22. Both the upper positioning frame 21 and the lower positioning frame 22 are provided with positioning grooves 23 that engage with the reinforcing bars. The upper positioning frame 21 is connected to the upper filling sleeve 11, and the lower positioning frame 22 is connected to the lower filling sleeve 12. The upper positioning frame 21 and the lower positioning frame 22 can be coaxially fixedly connected.

[0036] It is understood that the filling and holding device provided in this embodiment first fixes the steel bars in the upper sleeve 11 coaxially with the upper positioning frame 21 during operation, and fixes the steel bars in the lower sleeve 12 by filling the lower positioning frame 22. Then, the upper positioning frame 21 and the lower positioning frame 22 are coaxially fixed together to ensure that the steel bars will not be displaced due to impact when filling into the filling cavity, thereby avoiding the connection strength between the steel bars of the column and the cap beam being affected due to misalignment after filling.

[0037] Furthermore, the positioning unit 2 also includes two connecting seats 24, the outer walls of which are threaded. The outer wall of one connecting seat 24 is threaded to the inner wall of the upper filling sleeve 11, and the outer wall of the other connecting seat 24 is threaded to the inner wall of the lower filling sleeve 12. The upper positioning frame 21 and the lower positioning frame 22 are respectively disposed on the two connecting seats 24.

[0038] Understandably, the inner wall of the upper filling sleeve 11 is threaded with a connecting seat 24, on which an upper positioning frame 21 is mounted. The inner wall of the lower filling sleeve 12 is threaded with another connecting seat 24, on which a lower positioning frame 22 is mounted. The upper filling sleeve 11 and the lower filling sleeve 12 can be fixed together by coaxial fixed connection of the upper positioning frame 21 and the lower positioning frame 22, or fixed together by the two connecting seats 24.

[0039] In some embodiments, the positioning unit 2 further includes a connecting post 25 and a fixing member 26. The connecting post 25 passes through two connecting seats 24 in sequence and is then connected and fixed to the fixing member 26.

[0040] like Figure 3 and Figure 4 As shown, in this embodiment, the connecting seat 24 is roughly sleeve-shaped. A convex ring is arranged radially inside the connecting seat 24. The convex ring has a plurality of evenly spaced connecting holes arranged in a circular pattern. A plurality of connecting posts 25 pass through the connecting holes on the two connecting seats 24 in sequence and are connected and fixed to the fixing members 26 one by one, so as to realize the coaxial fixed connection of the two connecting seats 24, thereby realizing the coaxial fixation of the upper positioning frame 21 and the lower positioning frame 22 with inserted steel bars. This ensures the coaxiality of the steel bars of the cap beam and the steel bars of the posts during filling, and ensures the connection strength between the steel bars of the posts and the steel bars of the cap beam.

[0041] Furthermore, in this embodiment, both the upper positioning frame 21 and the lower positioning frame 22 are threadedly connected to the connecting seat 24. It is understood that by setting both the upper positioning frame 21 and the lower positioning frame 22 to be threadedly connected to the connecting seat 24, both the upper positioning frame 21 and the lower positioning frame 22 can move axially relative to the connecting seat 24, thereby positioning the ends of the reinforcing bars of the cap beam and the column at different distances. This ensures that during filling, the reinforcing bars of the cap beam can be limited by the positioning groove 23 of the upper positioning frame 21, and the reinforcing bars of the column can be limited by the positioning groove 23 of the lower positioning frame 22. This ensures the coaxiality of the reinforcing bars of the cap beam and the column, and guarantees the connection strength between the reinforcing bars of the column and the cap beam.

[0042] Furthermore, in this embodiment, the connecting seat 24 of the upper filling sleeve 11 and the connecting seat 24 of the lower filling sleeve 12 are both at least partially protruding.

[0043] like Figure 3 As shown, the connecting seat 24 disposed inside the upper filling sleeve 11 protrudes from the upper filling sleeve 11 at one end near the lower filling sleeve 12, and the protruding part can be provided with a boss in the radial direction, the boss being able to abut against the end face of the upper filling sleeve 11. The connecting seat 24 disposed inside the lower filling sleeve 12 protrudes from the lower filling sleeve 12 at one end near the upper filling sleeve 11, and the protruding part can be provided with a boss in the radial direction, the boss being able to abut against the end face of the lower filling sleeve 12.

[0044] Understandably, with this configuration, when the upper filling sleeve 11 and the lower filling sleeve 12 are arranged to form a filling cavity, the lower end of the upper filling sleeve 11 will not directly contact the upper end of the lower filling sleeve 12. Instead, they are connected together through two connecting seats 24. This not only avoids wear and tear on the upper filling sleeve 11 and the lower filling sleeve 12 during use, but also allows for positioning of the connecting seats 24, facilitating their installation.

[0045] Furthermore, in some embodiments, the ends of the two connecting seats 24 that are close to each other are chamfered. It is understood that, in order to further improve the coaxiality of the two connecting seats 24, while the two connecting seats 24 are fixedly connected by the connecting column 25 and the fastener 26, they are also fixed together by welding. By providing chamfers at the ends of the two connecting seats 24 that are close to each other, the chamfers on the two connecting seats 24 serve as welding bevels, facilitating welding operations while ensuring welding quality, and further improving the coaxiality between the reinforcing bars of the column and the reinforcing bars of the cap beam.

[0046] Furthermore, in this embodiment, the filling and holding device also includes a sealing element 3 and a locking ring 4. Both the locking ring 4 and the sealing element 3 are disposed at the end of the lower filling sleeve 12 away from the upper filling sleeve 11. The sealing element 3 is an elastic element, and the locking ring 4 enables the sealing element 3 to be tightly attached to the reinforcing bar of the column. It is understood that during the grouting process, the grout is prone to flow out from between the lower filling sleeve 12 and the reinforcing bar of the column due to gravity. By setting the sealing element 3 and the locking ring 4, the locking ring 4 has a locking opening larger than the diameter of the reinforcing bar of the column. The sealing element 3 is conical and is sleeved on the reinforcing bar of the column, with part of it extending out of the locking opening. When the locking ring 4 rotates and moves upward along the axis of the lower filling sleeve 12, it can press the sealing element 3 tightly onto the reinforcing bar of the column, achieving a stable sealing effect and ensuring that the grout does not flow out.

[0047] Furthermore, such as Figure 2 As shown, in this embodiment, a spacer 5 is provided on the locking ring 4. The spacer 5 is a spacer pad. The spacer 5 can fit tightly against the steel bar of the column when the locking ring 4 deforms. It can be understood that by providing the spacer 5, when the locking ring 4 moves upward to pressurize the sealing element 3, the sealing effect between the end of the lower filling sleeve 12 away from the upper filling sleeve 11 and the steel bar of the column can be further improved, thereby ensuring the filling effect.

[0048] Furthermore, in this embodiment, to reduce the impact of the grout on the reinforcing bars of the columns and the cover plate within the filling cavity and ensure the filling effect, a grouting port 121 is provided at the end of the lower filling sleeve 12 away from the upper filling sleeve 11, and a grout discharge port 111 is provided at the end of the upper filling sleeve 11 away from the lower filling sleeve 12. This arrangement allows the grout to rise against its own weight during the filling process, reducing the impact of the grout and further ensuring the coaxiality between the reinforcing bars of the columns and the cover beam during the filling process.

[0049] Furthermore, in some embodiments, multiple grouting ports 121 are provided at intervals along the circumference of the lower sleeve 12. This arrangement ensures the compactness, continuity, and integrity of the grouting, thereby guaranteeing the uniformity of the load-bearing capacity and durability of the structure after grouting, and improving the connection strength.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
