Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to an early demolition support structure for large-span beams. Background Technique

[0002] In the construction of concrete beam and slab structures in construction engineering, it is necessary to first set up formwork and a support system, and support the solidified concrete through the support device and the formwork to prevent the concrete from deforming and cracking due to insufficient solidification strength and lack of maintenance.

[0003] In order to save formwork and support materials, after the strength of the poured concrete reaches a certain strength specification requirement, the surrounding formwork and support system are often demolished so that the formwork can be used for subsequent construction.

[0004] Normally, connecting rods need to be added between existing support materials to enhance the stability of the support system. Although existing fasteners can lock and connect the connecting rod and the support column, when using fasteners to lock the connecting rod and the support column, the bolt will damage the anti-rust coating on the surface of the support column, which will then cause the support column to rust easily and affect the service life of the support column. Content of the Utility Model

[0005] The purpose of the utility model is to provide an early demolition support structure for large-span beams to solve the above deficiencies in the prior art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an early demolition support structure for large-span beams, including: a rotating rod and a tee pipe.

[0007] Further, an internal thread is provided in the rotating rod, and an external thread is provided on the outer wall of the support rod, and the external thread is threadedly connected with the internal thread.

[0008] Further, a plurality of annular grooves are equidistantly arranged on the outer side of the support rod, and a circlip for preventing relative sliding between the rotating rod and the support rod is clamped in the annular groove.

[0009] Further, a first embedded groove is provided at one end of the rotating rod inserted into the tee pipe, and one end of the silica gel block is embedded in the first embedded groove.

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0023] Please refer to FIGS. 1-3. A formwork early removal support structure for large-span beams includes: a rotating rod 1 and a tee pipe 3. One end of the rotating rod 1 is internally threaded with a support rod 2. The other end of the rotating rod 1 is inserted into the tee pipe 3, and the other end of the support rod 2 is also inserted into the tee pipe 3. A silica gel block 6 is arranged in the tee pipe 3. The tee pipe 3 is sleeved on a support column, and both the rotating rod 1 and the support rod 2 press the silica gel block 6 against the support column.

[0024] The tee pipe 3 is sleeved outside a support column that has been fixedly arranged on the ground. The support column can be inserted into the soil layer in the form of a concrete pile. A silica gel block 6 is placed in the pipe orifice of the tee pipe 3 connected to the rotating rod 1 or the support rod 2. The silica gel block 6 is cylindrical, avoiding direct contact between the rotating rod 1 or the support rod 2 and the support column, preventing the rust-proof coating on the support column from falling off. Also, a silica gel pad can be glued inside the tee pipe 3 to further protect the rust-proof coating on the support column.

[0025] Specifically, the present utility model rotates the rotating rod 1 to change the total length of the rotating rod 1 and the support rod 2, so that the ends of the rotating rod 1 and the support rod 2 inserted into the tee pipe 3 both press the silica gel block 6 inside it against the support column, fixing the rotating rod 1 and the support rod 2 at a certain height from the ground, avoiding damage to the rust-proof coating of the support column by bolts and extending the service life of the support column.

[0026] Furthermore, an internal thread 11 is provided inside the rotating rod 1, and an external thread 21 is provided on the outer wall of the support rod 2. The external thread 21 is threadedly connected to the internal thread 11. By rotating the rotating rod 1, the rotating rod 1 moves to the left relative to the support rod 2, thereby pressing the silica gel block 6 in the left tee pipe 3. After the extrusion force between the rotating rod 1 and the silica gel block 6 reaches a certain limit, both the rotating rod 1 and the support rod 2 press their respective corresponding silica gel blocks 6, fixing the rotating rod 1 and the support rod 2 between two support columns. The structure of this application is simple, easy to assemble, and convenient for replacing damaged parts, greatly reducing the maintenance cost and shortening the assembly time.

[0027] Furthermore, a plurality of annular grooves 22 are equidistantly arranged on the outer side of the support rod 2, and a snap ring 4 for preventing relative sliding between the rotating rod 1 and the support rod 2 is clamped in the annular grooves 22.

[0028] Specifically, refer toFigure 1 and Figure 3 A plurality of annular grooves 22 are formed in the support rod 2. When the rotating rod 1 and the support rod 2 are fixed between the two support columns, the snap ring 4 is snapped into the annular groove 22 to prevent relative movement between the rotating rod 1 and the support rod 2. In windy weather, large stresses on the internal thread 11 and the external thread 21 can be avoided, thus protecting the threads and reducing the possibility of easy rust caused by deformation due to excessive stress between the internal thread 11 and the external thread 21, and enhancing the connection strength between the rotating rod 1 and the support rod 2.

[0029] Further, a first embedded groove 12 is formed at one end of the rotating rod 1 inserted into the three-way pipe 3, and one end of the silica gel block 6 is embedded in the first embedded groove 12.

[0030] Specifically, referring to Figure 2 , by forming the first embedded groove 12 on the rotating rod 1, the axis of the silica gel block 6 can be made to coincide with the axis of the rotating rod 1, improving the locking effect of the support column by the three-way pipe 3.

[0031] Further, a second embedded groove 23 is formed at one end of the support rod 2 inserted into the three-way pipe 3, and one end of the silica gel block 6 is embedded in the second embedded groove 23.

[0032] Specifically, referring to Figure 3 , by forming the second embedded groove 23 on the support rod 2, the axis of the silica gel block 6 can be made to coincide with the axis of the support rod 2, improving the locking effect of the support column by the three-way pipe 3.

[0033] Further, an anti-slip sleeve 5 is fixedly sleeved on the outer side of the rotating rod 1.

[0034] Specifically, referring to Figure 1 , by fixedly sleeving the anti-slip sleeve 5 on the outside of the rotating rod 1, the friction between the staff's hand and the rotating rod 1 is increased, facilitating the installation of this application.

[0035] In this utility model, referring to Figures 1 to 3 , first, the two three-way pipes 3 are respectively sleeved on the two support columns. Then, the support rod 2 is threadedly connected to the rotating rod 1. Then, the silica gel block 6 is inserted into the first embedded groove 12 and the second embedded groove 23. Next, the end of the support rod 2 is inserted into the three-way pipe 3, and the rotating rod 1 is rotated so that the rotating rod 1 slides leftward relative to the support rod 2 and is inserted into the three-way pipe 3 to squeeze the silica gel block 6. Continue to rotate the rotating rod 1 until both the rotating rod 1 and the support rod 2 tightly press the silica gel block 6 against the support column, locking the rotating rod 1 and the support rod 2 to the support column. Finally, the snap ring 4 is snapped into the annular groove 22 to prevent relative sliding between the rotating rod 1 and the support rod 2.

[0036] Only some exemplary embodiments of the present utility model are described by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
