Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a reinforcement connection device for building high-support formwork. Background Art

[0002] High formwork refers to formwork operations when the formwork height is greater than or equal to eight meters. High formwork systems are required in the construction of high-rise halls and shared spaces such as public buildings. The stability and bearing capacity of high formwork must also be guaranteed during the installation process.

[0003] In the existing high-support formwork, the connection method between the horizontal bars and the vertical bars is single, and fasteners are often used to fix them at the intersection of the horizontal bars and the vertical bars. Although the fasteners can fix the connection parts of the high-support formwork, the vertical pressure on the entire high-support formwork is only borne by the fasteners, and the high-support formwork may tilt when the vertical bars are subjected to external forces, resulting in the inability to ensure the stability of the overall structure of the high-support formwork, and thus safety accidents. Utility Model Content

[0004] The utility model aims to provide a reinforcement connection device for building high formwork, which has the characteristics of strengthening the lateral and longitudinal stability of the high formwork, simple structure, convenient installation and good supporting effect.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a reinforcement connection device for building high formwork, comprising a support seat, two support rods are fixedly connected to the bottom of the support seat, the other ends of the two support rods are fixedly connected to pipe clamps, a telescopic rod is arranged at the top of the support seat, the other end of the telescopic rod is arranged with a first clamp, two screw rods distributed up and down are threadedly connected inside the support seat, and the opposite ends of the two screw rods are arranged with second clamps;

[0006] The screw comprises a main screw and a secondary screw, wherein the main screw and the secondary screw are connected end to end and their central axes coincide with each other, the thread directions of the outer walls of the main screw and the secondary screw are opposite, and the diameter of the secondary screw is smaller than that of the main screw.

[0007] In order to lock the fixing screw, as a preferred reinforcement connection device for building high-support formwork of the utility model, the outer wall of the auxiliary screw is threadedly connected with a fixing nut.

[0008] In order to facilitate the rotation of the screw rod, as a preferred reinforcement connection device for a high-rise building formwork of the utility model, one end of the auxiliary screw rod away from the main screw rod is fixedly connected with a rotating nut.

[0009] In order to facilitate the replacement and maintenance of the telescopic rod, as a preferred reinforcement connection device for a high-support formwork for construction of the utility model, a fixing plate is fixedly connected to the bottom of the telescopic rod, and the fixing plate is detachably connected to the support seat by bolts.

[0010] In order to prevent the angle of the clamp from being affected when the screw is rotated, as a preferred reinforcement connection device for a high-rise building formwork of the utility model, the first clamp is rotatably connected to the telescopic rod, and the second clamp is rotatably connected to the screw.

[0011] In order to facilitate the abutment and fixation with the horizontal bars and vertical bars, as a preferred reinforcement connection device for a high-rise building formwork of the utility model, the first clamping member and the second clamping member have the same structure and both have a triangular structure in cross-section.

[0012] In order to improve the support stability, as a preferred reinforcement connection device for a high-supported building formwork of the utility model, the two support rods are distributed in an "eight" shape and a reinforcing rod is fixedly connected between them.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] When the two second clamps are in contact with the outer wall of the left and right vertical bars, the two second clamps are moved outwards to support the two second bars, thereby ensuring that the two second clamps are in contact with the outer wall of the left and right vertical bars.

[0015] The screw includes a main screw and a secondary screw. When the overall extension length of the screw is adjusted, the fixing nut is rotated to firmly contact the outer wall of the support seat. At this time, since the thread directions are opposite, the screw can be locked in the position inside the support seat to prevent the screw from loosening and rotating, thereby improving the overall support effect.

[0020] See also Figures 1 to 3 A reinforcement connection device for building high formwork, comprising a support base 1, two support rods 2 are fixedly connected to the bottom of the support base 1, the other ends of the two support rods 2 are fixedly connected to a pipe clamp 3, a telescopic rod 4 is arranged at the top of the support base 1, the other end of the telescopic rod 4 is arranged with a first clamp 5, the interior of the support base 1 is threadedly connected with two screw rods 6 distributed up and down, and the opposite ends of the two screw rods 6 are arranged with a second clamp 7;

[0021] The screw 6 includes a main screw 8 and a secondary screw 9 , which are connected end to end and have their central axes coincident. The threads of the main screw 8 and the secondary screw 9 are in opposite directions and the diameter of the secondary screw 9 is smaller than that of the main screw 8 .

[0022] In this embodiment: during installation, if Figure 3 When the two second clamps 7 are respectively in contact with the outer walls of the left and right vertical bars, the two second clamps 7 are moved outwards, and the two second clamps 7 are respectively in contact with the outer walls of the left and right vertical bars, thereby supporting and fixing the two second clamps 7. When one of the two second clamps 7 is subjected to external force, the stressed rod or vertical bar is restrained by other rods and cannot be easily moved due to the existence of the connecting and fixing device, thereby enhancing the horizontal and vertical stability of the high formwork. At the same time, the device improves the supporting effect on the two adjacent horizontal bars, and shares the pressure on the fasteners at the intersection of the horizontal bar and the vertical bar, thereby improving the connection stability and the overall strength of the formwork. At the same time, the device has a simple structure and can be installed by one person. It is easy to install. The length of the clamps in the horizontal and vertical directions can be adjusted, which is convenient for adapting to horizontal and vertical bars with different spacings, and has strong applicability.

[0023] The screw rod 6 includes a main screw rod 8 and a secondary screw rod 9. When the overall extension length of the screw rod 6 is adjusted, the fixing nut 10 is rotated to firmly contact the outer wall of the support seat 1. At this time, since the thread directions are opposite, the screw rod 6 can be locked in the internal position of the support seat 1 to prevent the screw rod 6 from loosening and rotating, thereby improving the overall support effect.

[0024] Two pipe clamps 3 are arranged at the bottom, and a first clamp 5 with a triangular cross-section is arranged at the top. In the installation process of such a structure, the two pipe clamps 3 of one device and the first clamp 5 of another device are fixed to the outer wall of the same horizontal bar, and the vertical axes of the two pipe clamps 3 and the first clamp 5 are parallel, so they will not interfere with or affect each other, which is convenient for the installation of multiple devices. Second clamps 7 are used on both the left and right sides, and the sum of the horizontal thicknesses of the two second clamps 7 is less than the diameter of the vertical bar, so it will not affect the simultaneous fixing of the two second clamps 7 to the outer wall of the same vertical bar, which is convenient for installation.

[0025] As a technical optimization solution of the utility model, the outer wall of the auxiliary screw 9 is threadedly connected with a fixing nut 10 .

[0026] In this embodiment, the fixing nut 10 is rotated to firmly contact the outer wall of the support seat 1. At this time, since the thread directions are opposite, the screw rod 6 can be locked in the position inside the support seat 1.

[0027] As a technical optimization solution of the present invention, one end of the auxiliary screw 9 away from the main screw 8 is fixedly connected with a rotating nut 11 .

[0028] In this embodiment, one end of the auxiliary screw 9 away from the main screw 8 is fixedly connected with a rotating nut 11 , so that the screw 6 can be rotated conveniently by rotating the nut 11 .

[0029] As a technical optimization solution of the utility model, a fixing plate 12 is fixedly connected to the bottom of the telescopic rod 4, and the fixing plate 12 is detachably connected to the support seat 1 through bolts.

[0030] In this embodiment, the fixing plate 12 and the bolts are detachably connected to the support base 1, which is convenient for disassembly and assembly, and is easy for maintenance and replacement.

[0031] As a technical optimization solution of the utility model, the first clamping member 5 is rotatably connected to the telescopic rod 4 , and the second clamping member 7 is rotatably connected to the screw rod 6 .

[0032] In this embodiment: the first clamp 5 is rotatably connected to the telescopic rod 4, and the second clamp 7 is rotatably connected to the screw 6. This structure prevents the first clamp 5 and the second clamp 7 from rotating with the rotation of the screw 6, and can only move in the horizontal direction, so as to facilitate the abutment and fixation with the vertical rod and the horizontal rod.

[0033] As a technical optimization solution of the present utility model, the first clamping member 5 and the second clamping member 7 have the same structure and both have triangular cross-sections.

[0034] In this embodiment, the first clamping member 5 and the second clamping member 7 have the same structure and both have triangular cross-sections, which facilitates abutment and fixation with the vertical rod and the horizontal rod.

[0035] As a technical optimization solution of the utility model, the two support rods 2 are distributed in an "eight" shape and a reinforcing rod 13 is fixedly connected between them.

[0036] In this embodiment: the two support rods 2 are distributed in an "eight" shape and a reinforcing rod 13 is fixedly connected between them, so that after installation, they form a triangular structure with the cross bar to improve the support stability. The reinforcing rod 13 further improves the connection strength between the two support rods 2.

[0037] Working principle: During installation, the two pipe clamps 3 are fixedly clamped on the outer wall of the lower cross bar, and then the telescopic rod 4 is extended so that the first clamp 5 is abutted and fixed on the outer wall of the upper cross bar, and the two screw rods 6 are further rotated by rotating the nut 11. While the screw rod 6 rotates, the second clamp 7 at the other end is driven to move outward until the two second clamps 7 are respectively abutted against the outer walls of the vertical rods on the left and right sides, thereby supporting and fixing the cross bar and the vertical rod through this equipment. When one of the cross bars or vertical rods is subjected to external force, due to the presence of the connecting and fixing device, the stressed rod or vertical rod is restrained by other rods and cannot be easily moved, thereby enhancing the lateral and longitudinal stability of the high formwork. At the same time, the device improves the supporting effect on the two adjacent cross bars, and shares the pressure on the fasteners at the intersection of the cross bar and the vertical rod, thereby improving the connection stability and the overall strength of the formwork. At the same time, the equipment has a simple structure and can be installed by one person. It is easy to install, and the length of the clamps in the horizontal and vertical directions can be adjusted to adapt to cross and vertical rods with different spacings, and it has strong applicability.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
