[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] Example

[0024] like Figures 1-6 As shown, an impact-resistant hollow steel pipe includes: two hollow steel pipe bodies a1, two hollow steel pipe bodies b2 disposed on one side of the two hollow steel pipe bodies a1, a sleeve 3 installed at one end of the two hollow steel pipe bodies a1 and the two hollow steel pipe bodies b2, and a pressure-resistant component disposed between the two hollow steel pipe bodies a1 and the two hollow steel pipe bodies b2. The pressure-resistant component includes: a support rod 4, a pressure-resistant vertical rod 401, a connecting rod 402, and a pressure-resistant horizontal rod 403.

[0025] Both hollow steel pipe bodies a1 and b2 have insertion holes 7 on both sides of their top. Limiting screw holes 701 communicating with the insertion holes 7 are also provided on the outer sides of both hollow steel pipe bodies a1 and b2. When in use, the two hollow steel pipe bodies a1 and b2 are connected together by connecting rods 402 to form a support frame, which can then be placed in the foundation pit to support the formwork erection. The insertion rod at the bottom of the formwork is aligned with the insertion holes 7 on both sides of the top of the hollow steel pipe bodies a1 and b2 and inserted. A screw hole is provided on the outside of the rod. After insertion, the screw hole is aligned with the limiting screw hole 701 on the outside of the hollow steel pipe body a1 and hollow steel pipe body b2. Then, the screw is screwed into the screw hole from the limiting screw hole 701, thereby fixing the rod in the insertion hole 7. This fixes the template on the top of the hollow steel pipe body a1 and hollow steel pipe body b2, preventing the template from shifting. At this time, the two ends of the template rest against the top of the pit on both sides, and the hollow steel pipe body a1 and hollow steel pipe body b2 support the middle position of the template, so that the template is subjected to balanced force and the trolley remains stable when traveling on the template.

[0026] The hollow steel pipe body a1 and the hollow steel pipe body b2 are provided with support bases 8 at the bottom, and reinforcing rods 801 are arranged inside the support bases 8.

[0027] The two hollow steel pipe bodies a1 and the two hollow steel pipe bodies b2 are provided with support rods 4, and the two hollow steel pipe bodies a1 and the two hollow steel pipe bodies b2 are provided with compression vertical rods 401, connecting rods 402 and compression horizontal rods 403. During use of the hollow steel pipe bodies a1 and the hollow steel pipe bodies b2, the compression vertical rods 401 and the compression horizontal rods 403 can enhance the impact resistance of the hollow steel pipe bodies a1 and the hollow steel pipe bodies b2, so that the hollow steel pipe bodies a1 and the hollow steel pipe bodies b2 have good stability and support, and the hollow steel pipe bodies a1 and the hollow steel pipe bodies b2 are prevented from shaking when supporting the formwork, thereby reducing the safety hazards during material transportation.

[0028] The hollow steel pipe bodies a1 and the hollow steel pipe bodies b2 are provided with built-in steel sheets 6 inside. The built-in steel sheets 6 are hexagonal in structure. During use of the hollow steel pipe bodies a1 and the hollow steel pipe bodies b2, the built-in steel sheets 6 can improve the support impact stress of the hollow steel pipe bodies a1 and the hollow steel pipe bodies b2, and prevent the hollow steel pipe bodies a1 and the hollow steel pipe bodies b2 from deforming after bearing weight.

[0029] The two hollow steel pipe bodies a1, the two hollow steel pipe bodies b2 and the sleeves 3 are provided with fixed screw holes 5 at the top, and fixed screw rods 501 are screwed into the fixed screw holes 5. When two frame bodies are combined together, the sleeve 3 at one end of the hollow steel pipe body a1 and the hollow steel pipe body b2 is inserted into the other end of the other hollow steel pipe body a1 and the hollow steel pipe body b2. At this time, the fixed screw holes 5 at the top of the sleeve 3 are aligned with the fixed screw holes 5 at the top of the hollow steel pipe body a1 and the hollow steel pipe body b2. The fixed screw rods 501 are screwed into the fixed screw holes 5 and tightened, so that the two frame bodies can be fixed and installed, and can be used to support larger formwork.

[0030] The bottom of the support base 8 is provided with an extension support pipe 9, and a threaded head 901 is welded at the top of the extension support pipe 9 and is screwed with the support base 8. When the foundation pit is deep, the extension support pipe 9 at the bottom of the support base 8 can be flexibly disassembled, and different lengths of extension support pipes 9 can be installed at the bottom of the support base 8, so that the hollow steel pipe bodies a1 and b2 have enough height to fit and install the formwork, thereby achieving the supporting effect.

[0031] When the extension support pipe 9 is installed, the threaded head 901 at the top of the extension support pipe 9 is screwed into the bottom of the support base 8 and is screwed with the support base 8 until the extension support pipe 9 is connected with the bottom of the support base 8.

[0032] Working principle:

[0033] When the two hollow steel pipe bodies a1 and the two hollow steel pipe bodies b2 are used, they are connected together by the connecting rod 402 to form a support frame body, which can be placed in the foundation pit for supporting the formwork erection. The insertion rod at the bottom end of the formwork is aligned with the insertion hole 7 at the top of the two sides of the hollow steel pipe bodies a1 and b2 and is inserted. The insertion rod has a screw hole outside. After insertion, the screw hole is aligned with the limiting screw hole 701 outside the hollow steel pipe bodies a1 and b2. Then the screw rod is screwed into the screw hole from the limiting screw hole 701, thereby fixing the insertion rod in the insertion hole 7, so that the formwork is fixed on the top of the hollow steel pipe bodies a1 and b2, avoiding displacement of the formwork. At this time, the formwork is supported on both sides of the top of the foundation pit, and the hollow steel pipe bodies a1 and b2 support the middle position of the formwork, so that the formwork is balanced, ensuring the stability of the car when driving on the formwork.

[0034] During the use of the hollow steel pipe bodies a1 and b2, the setting of the compression vertical rod 401 and the compression horizontal rod 403 can enhance the impact resistance of the hollow steel pipe bodies a1 and b2, so that the hollow steel pipe bodies a1 and b2 have good stability and support, avoiding shaking of the hollow steel pipe bodies a1 and b2 when supporting the formwork, and reducing the safety hidden danger during material transportation.

[0035] When the hollow steel pipe bodies a1 and b2 are placed in the foundation pit for supporting the formwork, the bottom of the hollow steel pipe bodies a1 and b2 are placed by the support base 8, so that the hollow steel pipe bodies a1 and b2 are not directly contacted in the soil layer, the hollow steel pipe bodies a1 and b2 are prevented from being corroded and damaged, and the service life of the hollow steel pipe bodies a1 and b2 can be prolonged. When the foundation pit is deep, the extension branch pipes 9 at the bottom of the support base 8 can be flexibly disassembled, and different lengths of the extension branch pipes 9 can be installed at the bottom of the support base 8, so that the hollow steel pipe bodies a1 and b2 have sufficient height to fit and install the formwork, and the supporting effect is achieved.
