Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a locking and reinforcing device for column formwork. Background Technology

[0002] In building construction, formwork, as a core building material, shines in the pouring of walls and floor slabs due to its standardized dimensions and high-quality uniformity. It not only improves construction efficiency and quality and ensures structural strength and stability, but also promotes the greening of building construction through its high reusability and durability. It has made important contributions to the sustainable development and energy conservation and emission reduction of the construction industry. Looking to the future, formwork will continue to play a key role in building a safe, environmentally friendly and efficient building environment.

[0003] Traditional column formwork fixing methods typically rely on fasteners such as bolts and threaded rods. These fasteners require multiple adjustments during installation to ensure that the formwork fits tightly against the pouring surface. However, this fixing method is not only time-consuming and labor-intensive, but also difficult to adapt to pouring surfaces of different thicknesses and shapes. In addition, traditional fixing methods also pose a risk that fasteners may loosen or fall off, creating potential safety hazards during construction. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a locking and reinforcement device for column formwork is provided to solve the problem that column formwork is prone to loosening and falling off when reinforced with traditional fasteners such as bolts and screws.

[0005] To achieve the above objectives, a locking and reinforcing device for column formwork is provided, comprising:

[0006] Two first pull rod assemblies arranged opposite to each other include an outer sleeve, an inner sleeve, and a drive rod. One end of the inner sleeve is slidably disposed in one end of the outer sleeve. The inner sleeve has an internal thread, and the drive rod has an external thread. The drive rod is rotatably mounted in the outer sleeve and screwed into the inner sleeve.

[0007] Two second tie rod assemblies include a socket sleeve and a plug rod. One end of the plug rod is slidably disposed in one end of the socket sleeve. The socket sleeve has a through hole, in which a locking member is elastically installed. One end of the locking member extends into the socket sleeve. One end of the plug rod has a first anti-reverse groove, and one end of the locking member has a second anti-reverse groove. The second anti-reverse groove engages with the first anti-reverse groove. One second tie rod assembly is connected between the other ends of the outer sleeves of the two first tie rod assemblies, and the other second tie rod assembly is connected between the other ends of the inner sleeves of the two first tie rod assemblies. The two first tie rod assemblies and the two second tie rod assemblies enclose a locking space for being fitted onto the outside of the column formwork.

[0008] Furthermore, an end-sealing plate is formed at the other end of the outer sleeve, and the end-sealing plate has a through hole, in which the drive rod is rotatably installed.

[0009] Furthermore, the inner wall of the outer sleeve is provided with a first guide groove, which is arranged along the axial direction of the outer sleeve, and the outer wall of the inner sleeve is formed with a first slider, which slides in the first guide groove.

[0010] Furthermore, there are two guide grooves, which are respectively disposed on the inner walls of opposite sides of the outer sleeve.

[0011] Furthermore, the first pull rod assembly is arranged perpendicularly to the second pull rod assembly.

[0012] Furthermore, the inner walls on opposite sides of the through hole are respectively provided with second guide grooves, and the locking member has second sliders on opposite sides, the second sliders being slidably disposed in the second guide grooves.

[0013] Furthermore, the locking member is connected to a lifting rod, which is arranged along the axial direction of the through hole, and one end of the lifting rod extends to the outside of the socket sleeve.

[0014] Furthermore, an anti-detachment flange is formed at the end of the through hole away from the plug rod, and a push spring is provided between the locking member and the anti-detachment flange.

Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1 to 4 As shown, this utility model provides a locking and reinforcing device for column formwork, including: a first tie rod assembly 1 and a second tie rod assembly 2.

[0025] There are two first tie rod assemblies 1 and two second tie rod assemblies 2. The two first tie rod assemblies 1 and the two second tie rod assemblies 2 are connected to form a frame structure. The first tie rod assemblies 1 and the second tie rod assemblies 2 are arranged alternately.

[0026] Specifically, the two first pull rod assemblies 1 are arranged opposite each other. Each first pull rod assembly 1 includes an outer sleeve 11, an inner sleeve 12, and a drive rod 13.

[0027] One end of the inner sleeve 12 is slidably disposed within one end of the outer sleeve 11. The inner sleeve 12 has an internal thread. The drive rod 13 has an external thread. The drive rod 13 is rotatably mounted within the outer sleeve 11. The drive rod 13 is screwed into the inner sleeve 12.

[0028] The second tie rod assembly 2 includes a socket sleeve 21 and a connector rod 22. In this embodiment, the outer sleeve, inner sleeve, socket sleeve, and connector rod have rectangular cross-sections.

[0029] One end of the insertion rod 22 is slidably disposed within one end of the socket sleeve 21. The socket sleeve 21 has a through hole. A locking member 23 is elastically installed in the through hole. One end of the locking member 23 extends into the socket sleeve 21. One end of the insertion rod 22 has a first anti-reverse groove. One end of the locking member 23 has a second anti-reverse groove. The second anti-reverse groove engages with the first anti-reverse groove.

[0030] A second tie rod assembly 2 is connected between the other ends of the outer sleeve 11 of the two first tie rod assemblies 1. Another second tie rod assembly 2 is connected between the other ends of the inner sleeve 12 of the two first tie rod assemblies 1. The two first tie rod assemblies 1 and the two second tie rod assemblies 2 together form a locking space for being fitted onto the outside of the column formwork.

[0031] See Figure 2 As shown, an end-sealing plate is formed at the other end of the outer sleeve 11. The end-sealing plate has a through hole. The drive rod 13 is rotatably mounted in the through hole.

[0032] Continue reading Figure 2 As shown, a first guide groove is formed on the inner wall of the outer sleeve 11. The first guide groove is arranged along the axial direction of the outer sleeve 11. A first slider 121 is formed on the outer wall of the inner sleeve 12. The first slider slides in the first guide groove.

[0033] In this embodiment, there are two guide grooves. The two guide grooves are respectively disposed on the inner walls of opposite sides of the outer sleeve 11.

[0034] In a preferred embodiment, the first tie rod assembly 1 and the second tie rod assembly 2 are arranged perpendicularly. The frame structure formed by connecting the two first tie rod assemblies 1 and the two second tie rod assemblies 2 is rectangular. The shape of the inner frame opening of the frame structure is adapted to the shape of the column's cross-section.

[0035] Combination Figure 3 and Figure 4 As shown, second guide grooves are respectively formed on the inner walls of opposite sides of the through hole of the socket sleeve. Second sliders are formed on opposite sides of the locking member 23, and the second sliders slide in the second guide grooves.

[0036] In this embodiment, the locking member 23 is connected to a lifting rod 24. The lifting rod 24 is arranged along the axial direction of the through hole. One end of the lifting rod 24 extends to the outside of the socket sleeve 21.

[0037] In a preferred embodiment, an anti-detachment flange is formed at the end of the through hole away from the insertion rod 22. A push spring 25 is provided between the locking member 23 and the anti-detachment flange.

[0038] In this embodiment, the push spring is a helical spring. The push spring is sleeved on the outside of the lifting rod. The two ends of the push spring abut against the locking element and the anti-detachment flange, respectively.

[0039] During column formwork construction, after the column formwork is erected, two first tie rod assemblies are respectively placed on opposite sides of the column formwork. Then, the drive rod is rotated, causing the inner sleeve to move axially along the outer sleeve until the length of the first tie rod assembly matches the width of the column's cross-section. This means the socket sleeves and insertion rods at both ends of the first tie rod assembly clamp and fix the formwork, providing a locking and reinforcing effect. Simultaneously, the length of the second tie rod assembly is adjusted by changing the insertion depth of the insertion rod in the socket sleeve, ensuring its length matches the length of the column's cross-section. Finally, the second anti-reverse groove of the locking element engages with the first anti-reverse groove on the insertion rod to fix the length of the second tie rod assembly. Thus, the two first tie rod assemblies and two second tie rod assemblies connect to form a frame structure, which limits the tension on both sides of the formwork. This column formwork locking and reinforcing device of this invention can comprehensively limit and fix the formwork.

[0040] The locking and reinforcing device for column formwork of this utility model clamps and fixes the column formwork, which can lock and reinforce the formwork and prevent the formwork from expanding outward when pouring concrete slurry.

[0041] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
