Description

Technical Field

[0001] This utility model relates to the technical field of single-sided template installation structure, and in particular to a rotatable connection installation structure for a single-sided template. Background Technology

[0002] In construction engineering, especially in nuclear power plant environments, situations often arise where formwork and concrete pouring can only be carried out from one side, such as raft foundations and replacement projects involving large-volume concrete pouring. In such cases, it is not possible to install tie bolts on both sides of the formwork as in conventional construction, making the fixation and stability of the formwork a technical challenge. Currently, the main method for fixing single-sided formwork is through internal tie rods, where one end of the rebar is bent and welded to a through-wall bolt. However, due to factors such as the formwork connection height, the bending angle of the rebar is uncontrollable, and the tie rods are often rigid or have non-adjustable connection points. Furthermore, bending the rebar not only causes deviations at the joints, which is detrimental to the overall stress distribution, but also makes it difficult to reuse the welded rebar, resulting in cost waste. Utility Model Content

[0003] This utility model provides a rotatable connection and installation structure for a single-sided template, which solves the technical problems of traditional tie-in methods, such as the inability to control the support angle of the reinforcing bars, installation deviation, and difficulty in reuse.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A rotatable connection installation structure for a single-sided formwork includes a lateral wall, a single-sided formwork arranged parallel to the lateral wall, rebars set on the foundation and located in the area to be poured, tie rods set on the single-sided formwork, internal reinforcing bars connecting the tie rods and the rebars, and a connector set between the top of the internal reinforcing bars and the tie bolts. The area between the side wall and the single-sided formwork is the area to be poured. The adapter includes a first sleeve, a second sleeve, ear plates arranged parallel to the upper part of the side wall of the first sleeve, and a pin connecting the two parallel ear plates and the second sleeve. The first sleeve and the second sleeve are rotatably connected by a pin.

[0005] Furthermore, the first sleeve is a linear sleeve, and the first sleeve is connected to the top of the inner reinforcing bar.

[0006] Furthermore, a retaining ring is provided at the bottom end of the internal tie bar, and the retaining ring is connected to the rebar sleeve.

[0007] Furthermore, the bottom end of the inner reinforcing bar is connected to the retaining ring by compression or welding.

[0008] Furthermore, the second sleeve has internal threads. The surface of the tie rod is provided with an external thread that matches the internal thread, and the two are connected by the thread.

[0009] Furthermore, it also includes the main keel, which is vertically installed on the side of the single-sided formwork away from the area to be poured; The main keel is set at intervals in the vertical direction on one side of the template; Secondary keels are provided on the outside of the main keel; the secondary keels are set horizontally and are set at vertical intervals on the main keel; The main keel and secondary keel are made of wood or square steel.

[0010] Furthermore, it also includes a U-shaped clip and a nut that are sequentially inserted into the tie rod, and the secondary keel is pressed against the side surface of the main keel by the U-shaped clip and the nut.

[0011] Furthermore, tie rods are spaced vertically and horizontally on one side of the template, and the connecting parts, internal reinforcing bars and anchor bars are matched with the tie rods one by one.

[0012] The beneficial effects of this utility model are reflected in: 1) This utility model achieves adaptive adjustment of the angle between the internal reinforcing bar and the tie rod through a rotatable connecting adapter, which significantly improves the convenience and accuracy of single-sided formwork installation.

[0013] 2) This utility model provides a solid root anchorage for the entire tie system by pre-embedding the rebar in the foundation, which greatly enhances the formwork structure's resistance to pull-out under concrete lateral pressure and its overall stability.

[0014] 3) This utility model achieves rapid assembly, disassembly and reuse of the tie rod through the detachable structure of the tie rod, which effectively improves the material utilization rate and construction economy.

Detailed Implementation

[0018] Taking a single-sided formwork installation structure as an example, in order to reduce the installation difficulty and improve construction efficiency, the following methods were used: Figure 1-5 Construction is carried out using the rotatable connection and installation structure of the single-sided template shown. In this embodiment, the rotatable connection installation structure of the single-sided template includes a side wall 2, a single-sided template 3 arranged parallel to the side wall 2, a reinforcing bar 6 set on the foundation 1 and located in the area to be poured 4, a tie rod 101 set on the single-sided template 3, an inner reinforcing bar 7 connecting the tie rod 101 and the reinforcing bar 6, and a transition piece 9 set between the top of the inner reinforcing bar 7 and the tie bolt. The area to be poured 4 is between the side wall 2 and the single-sided template 3, and the transition piece 9 serves as the connection hub, realizing the force flow transmission between the inner reinforcing bar 7 and the tie rod 101.

[0019] In this embodiment, the adapter 9 includes a first sleeve 91, a second sleeve 93, an ear plate 92 parallel to the upper side wall of the first sleeve 91, and a pin 94 connecting the two parallel ear plates 92 and the second sleeve 93. The first sleeve 91 and the second sleeve 93 are rotatably connected by the pin 94. This connection method allows the inner reinforcing bar 7 and the tie rod 101 to swing freely within a certain angle range. The adapter 9 enables the rebar 6-inner reinforcing bar 7 structure and the tie rod 101 template structure to be rotatably connected, avoiding the additional bending moment and stress concentration that will occur when there is a deviation in the traditional rigid connection, so that the tie force can be transmitted more purely along the direction of the rod.

[0020] In this embodiment, the top end of the inner pull-bar 7 is sleeved with the first sleeve 91. Specifically, the top end of the inner pull-bar 7 and the first sleeve 91 can be connected by extrusion or by thread. The sleeve connection allows the inner pull-bar 7 to have a certain amount of movement within the sleeve. The bottom end of the inner pull-bar 7 is welded or extruded to a retaining ring 8, which is sleeved with the anchor bar 6. This detachable connection facilitates quick installation and disassembly. In another embodiment, the bottom end of the inner pull-bar 7 is welded to the anchor bar 6. This connection method provides extremely high connection strength and reliability.

[0021] The second sleeve 93 has an internal thread, and the surface of the tie rod 101 has an external thread that matches the internal thread. The two are connected by thread engagement.

[0022] In another embodiment, a support component 5 is also included on the side of the single-sided template 3 away from the area to be poured 4. The support component 5 includes a vertical main keel 51 and a horizontal secondary keel 52 on the side of the main keel 51 away from the area to be poured 4. The main keel 51 is used to distribute and transmit the concentrated force of the tie rod 101 to the template panel, and the secondary keel 52 is used to evenly transmit the pressure of the fastener to the main keel 51. The two work together to greatly enhance the overall rigidity and stability of the template system. There are multiple main keels 51, which are equidistantly arranged above the foundation 1 in the horizontal direction. There are multiple secondary keels 52, which are symmetrically arranged on both sides of the tie rod 101. In terms of material selection, the main keel 51 and the secondary keel 52 can be timber or square steel.

[0023] In another embodiment, a fixing component 10 is also provided on the side of the secondary keel 52 away from the area to be poured 4. The fixing component 10 includes a tie rod 101 and a U-shaped clip 102 and a nut 103 sequentially passing through the tie rod 101. The secondary keel 52 is pressed against the side surface of the main keel 51 by the U-shaped clip 102 and the nut 103. By tightening the nut 103, the U-shaped clip 102 presses the secondary keel 52 tightly onto the main keel 51, thereby providing the entire template system with a final, adjustable, and powerful locking force.

[0024] In another embodiment, according to actual engineering needs, multiple adapters 9 can be set, with multiple adapters 9 spaced apart on one side of the template 3 in a vertical or horizontal direction; multiple reinforcing bars 6 can be set, with multiple reinforcing bars 6 pre-embedded in the foundation 1 at intervals in a horizontal direction; multiple internal reinforcing bars 7 can be set, with multiple internal reinforcing bars 7 respectively set between the corresponding adapters 9 and the reinforcing bars 6; multiple tie rods 101 can be set, with multiple tie rods 101 respectively connected to the corresponding adapters 9 on one side of the template 3. Through multi-point arrangement, a uniform force network is formed on the back of the template to jointly resist the lateral pressure of the concrete, effectively preventing local bulging or overall displacement of the template, and ensuring the flatness and verticality of the cast body.

[0025] In actual construction, firstly, holes are drilled at the predetermined position of foundation 1 and rebar 6 is inserted. Secondly, the internal tie bar 7 system with adapter 9 is connected to the rebar 6. Then, the single-sided formwork 3 and back bracing system are initially installed, so that the tie rod 101 is connected to the adapter 9. Finally, the formwork position is adjusted to the design elevation and vertical. Then, the nuts 103 on all tie rods 101 are tightened in sequence to finally tighten and accept the formwork.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any changes or substitutions conceived by those skilled in the art within the scope of the technology disclosed in this utility model should be included within the scope of protection of this utility model.
