Description

Technical Field

[0001] This application belongs to the field of cast-in-place pile construction technology, specifically relating to a cast-in-place pile guide pipe support device. Background Technology

[0002] Cast-in-place piles are foundation components formed by drilling or excavating holes and then pouring concrete into them. The core technology involves using a tremie pipe method for concrete pouring. The bottom of the tremie pipe is inserted into the mud in the pile hole, and concrete is continuously transported through the pipe while it is being lifted. The weight of the concrete displaces the mud, forming a dense pile. This technology is widely used for foundation reinforcement in construction projects such as buildings and bridges, and is characterized by high bearing capacity and strong adaptability.

[0003] The existing support device for cast-in-place pile guide pipes cannot be flexibly adjusted. When the pipe diameter changes, it cannot be adapted. Either it needs to be redesigned and manufactured according to the new guide pipe, or the original device needs to be modified and adjusted. Both of these methods bring complicated work tasks and are not conducive to the full utilization of the original device, resulting in waste. Utility Model Content

[0004] The purpose of this application is to provide a support device for cast-in-place pile guide pipes, which solves the problem that the existing support devices for cast-in-place pile guide pipes cannot be flexibly adjusted.

[0005] The objective of this application is achieved through the following technical solution:

[0006] A cast-in-place pile guide pipe support device includes two opposing longitudinal beams and two opposing transverse beams arranged between them. Both ends of the transverse beams are slidably mounted on the longitudinal beams. Each transverse beam is hinged with a flap, both ends of which are mounted on the longitudinal beams. Opposing guide pipe holes are opened on the two flaps. The upper guide pipe is connected to a connector, which is mounted on the two flaps and connected to the lower guide pipe. The lower guide pipe passes through the guide pipe holes.

[0007] Furthermore, both the longitudinal beams and the transverse beams are made of channel steel.

[0008] Furthermore, the two longitudinal beams are placed at the opening of the pile hole.

[0009] Furthermore, the perforation of the conduit is located at the center between the two flaps.

[0010] Furthermore, both crossbeams are slidably mounted on the longitudinal beams.

[0011] Furthermore, both ends of the crossbeam are connected to locking sleeves, which are fitted onto the longitudinal beam. The locking sleeves are fitted with pins, and the longitudinal beam has several locking holes.

[0012] Furthermore, the flap is hinged to the crossbeam via at least two hinges.

[0013] Furthermore, the flip panel is equipped with a handle.

[0014] Furthermore, the connector includes a cap and an enlarged end, the upper conduit is connected to the cap, the cap is connected to the enlarged end, the enlarged end is mounted on two flaps, and the enlarged end is connected to the lower conduit.

[0015] Furthermore, the upper conduit is connected to the cap via a flange, the cap is connected to the enlarged end via a threaded connection, and the enlarged end is connected to the lower conduit via a flange.

[0016] The beneficial effects of this application are:

[0017] (1) By sliding the crossbeams on the longitudinal beams, the distance between the two relative crossbeams can be adjusted, thereby changing the size of the guide tube perforation between the flaps to adapt to guide tubes of different diameters.

[0018] (2) The crossbeams and longitudinal beams are connected to form a grid-shaped structure, which enables the device to be arranged and installed at the wellhead of the pile hole. It is applicable to various pile hole diameters, has good support strength, and has a simple structure.

[0019] The aforementioned main solution and its various further alternatives can be freely combined to form multiple solutions, all of which are solutions that can be adopted and claimed in this application; furthermore, the (non-conflicting alternatives) can also be freely combined with each other and with other alternatives. Those skilled in the art, after understanding this solution, will realize from the prior art and common general knowledge that there are many combinations, all of which are technical solutions to be protected in this application, and will not be exhaustively listed here.

[0022] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0023] Example

[0024] refer to Figure 1 As shown, a cast-in-place pile guide pipe support device includes a longitudinal beam 1, a transverse beam 2, a flap 3, an upper guide pipe 4, a connector 5, a lower guide pipe 6, a pile hole 7, a locking sleeve 8, a pin 9, a hinge 10, and a handle 11.

[0025] The longitudinal beam 1 has two parallel beams arranged opposite each other, and the transverse beam 2 also has two parallel beams arranged opposite each other. The two opposite longitudinal beams 1 are arranged with two opposite transverse beams 2, so that the longitudinal beams 1 and transverse beams 2 form a grid-shaped (or II-shaped) frame structure to realize the placement of other components, as well as the placement at the opening of the pile hole 7.

[0026] Both ends of the crossbeam 2 are slidably mounted on the longitudinal beam 1, so that at least one crossbeam 2 can slide and adjust relative to the longitudinal beam 1, thereby changing the distance between the two crossbeams 2 to accommodate the installation of conduits of different diameters.

[0027] Two flaps 3 are hinged to both crossbeams 2. The two flaps 3 are located between the two crossbeams 2. When the conduit is disassembled or assembled, the flaps 3 can be opened to facilitate the installation and removal of the conduit or other equipment. The two ends of the flaps 3 are placed on the longitudinal beams 1, that is, the longitudinal beams 1 support the flaps 3 so that the flaps 3 cannot be flipped downwards. Thus, the flaps 3 provide a supporting surface for locking the joint.

[0028] The upper conduit 4 is connected to the connector 5, which is placed on two flaps 3. The connector 5 is also connected to the lower conduit 6, which is inserted into the conduit perforation. The two flaps 3 have corresponding conduit perforations, which are slightly larger than the conduit but smaller than the connector 5, allowing the conduit to be inserted. The connector 5 can be secured to the flaps 3 to provide overall support for the conduit.

[0029] Both longitudinal beam 1 and transverse beam 2 are channel steel, possessing good structural strength and capable of supporting the guide pipe. Similarly, longitudinal beam 1 and transverse beam 2 can also be made of I-beams or other structures. Since the two longitudinal beams 1 are relatively long, they are placed at the opening of the pile hole 7.

[0030] The guide pipe perforation is located at the center between the two flaps 3, which facilitates the alignment of the guide pipe on the pile hole 7, while ensuring reliable support of the guide pipe by the flaps 3.

[0031] Both crossbeams 2 are slidably mounted on the longitudinal beam 1, meaning that both crossbeams 2 can slide and adjust along the longitudinal beam 1.

[0032] Both ends of the crossbeam 2 are welded to the locking sleeves 8. The locking sleeves 8 are rectangular sleeves that fit onto the longitudinal beam 1. That is, the crossbeam 2 is adjusted by sliding through the locking sleeves 8. A pin 9 passes through the locking sleeve 8. The longitudinal beam 1 has several locking holes. By passing the pin 9 through both the locking sleeve 8 and the longitudinal beam 1, the crossbeam 2 is fixed to the longitudinal beam 1. By pulling out the pin 9, the position of the crossbeam 2 can be adjusted.

[0033] The outer side of the flap 3 is hinged to the crossbeam 2 by at least two hinges 10 to ensure the reliable flipping of the flap 3. The flap 3 is provided with handles 11, which are arranged at both ends of the flap 3 and located on the inner side of the flap 3, so as to facilitate lifting the flap 3 to realize the opening and closing of the flap 3.

[0034] The connector 5 includes a cap 12 and an enlarged end 13. The upper conduit 4 is connected to the cap 12 via a flange, and the cap 12 and the enlarged end 13 are connected by threads. The enlarged end 13 is mounted on two flaps 3 and is connected to the lower conduit 6 via a flange.

[0035] When in use, place the entire device at the opening of the pile hole 7, open the flap 3, insert the lower guide tube 6, then install the connector 5, and finally install the upper guide tube 4 and pour concrete.

[0036] The foregoing basic examples and their further alternative examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed in this application. In the scheme of this application, each alternative example can be arbitrarily combined with any other basic example and alternative example.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
