Description

Technical Field

[0001] The utility model relates to the field of building construction equipment, in particular to a construction support traction device. Background Art

[0002] In the construction of side walls of underpass overpasses in traffic engineering, the main bearing body of the side wall is the concrete pile wall. As the facing wall of the pile body wall, the smooth appearance of the concrete side wall is the most important. The formwork construction of the side wall cannot be applied to the traditional wall formwork mode. Generally, the concrete is poured using the inner support side formwork. Since the side wall is a single-side structure, the inner side needs to be connected to the bored pile row as a whole. When the formwork is erected, the traditional through-pull rod cannot be used to limit the formwork. The side wall formwork can only be constructed by using the inner support bracket to support the two sides as a whole and pouring the concrete simultaneously.

[0003] In the existing technology, the dismantling and relocation of the internal support bracket in the side wall construction is the most labor-intensive and time-consuming. Since the side wall construction of the underpass overpass is to cast a 20-meter side wall at a time, the overall volume of the construction bracket is relatively large. If the traditional dismantling and relocation process is used, it will take a week to complete once, resulting in a tight construction period, heavy tasks, and serious labor and time consumption.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example

[0027] Please refer to Figure 1-Figure 4 , which is a schematic diagram of the structure of the construction support traction device in the embodiment of the utility model;

[0028] The present embodiment provides a construction support traction device for supporting and traction of a construction support 1, comprising at least two load-bearing tubes 2, one end of the load-bearing tube 2 is provided with a connecting plate 3, the plane where the bottom of the connecting plate 3 is located is higher than the plane where the bottom of the load-bearing tube 2 is located, and the end of the connecting plate 3 away from the load-bearing tube 2 is provided with a traction member 4, which is used to connect to a traction machine; wherein the diameter of the load-bearing tube 2 is greater than the extended length of the bottom of the construction support 1, so that when the load-bearing tube 2 supports the construction support 1, the construction support 1 is suspended in the air.

[0029] Next, the construction support traction device of this exemplary embodiment will be further described.

[0030] In some embodiments of the present application, the bearing tube 2 is a steel tube with a diameter of 80 mm and a length of 22 m, which has sufficient supporting strength and sufficient length to pass through the bottom of the construction support 1. A connecting plate 3 is provided at one end of the bearing tube 2. The connecting plate 3 is a steel plate. The plane where the bottom of the connecting plate 3 is located is higher than the plane where the bottom of the bearing tube 2 is located. Specifically, the connecting plate 3 is welded to the top of one end of the bearing tube 2. The connection is made firmer by welding to avoid separation during traction. The traction spacing makes the connecting plate 3 a traction connection member during traction, which is convenient for connection and does not affect the sliding of the bearing tube 2. A traction member 4 is provided at one end of the connecting plate 3 away from the bearing tube 2. The traction member 4 is used to connect to the traction machine; wherein, the diameter of the bearing tube 2 is greater than the extension length of the bottom of the construction support 1, so that when the bearing tube 2 supports the construction support 1, the construction support 1 is suspended in the air, and all the weight of the construction support 1 is carried on the two bearing tubes 2. The traction machine can be an excavator used in on-site construction, which is connected to the traction member 4 through a traction steel rope 6. When the excavator moves forward, the traction member 4 and the connecting plate 3 pull the load-bearing pipe 2 to slide on the ground, thereby pulling the construction support to shift.

[0031] It should be noted that when inserting the two supporting pipes 2, the construction support 1 needs to be slightly lifted upwards to facilitate insertion. Since the construction support 1 is large in size, it can be lifted by an on-site equipment crane, or lifted upwards by equipment such as a jack.

[0032] In a specific embodiment, during operation, the construction support 1 is lifted (hoisted) and inserted into two symmetrical load-bearing pipes 2, and the load-bearing pipes 2 are pulled to the front segment construction surface by an excavator. Then, the construction support 1 is lifted (hoisted) and the load-bearing pipes 2 are pulled out. After the left and right supports are pulled into place, most of the work of side wall formwork support is completed. This improvement saves about 5 days in each segment construction cycle and also saves a lot of manpower investment.

[0033] In some embodiments of the present application, a support pipe 5 is further included, and the support pipe 5 is transversely connected between the two connecting plates 3. The support pipe 5 is a steel pipe with a diameter of 48 mm. By arranging the support pipe 5 between the two connecting plates 3, the two bearing pipes 2 can be supported and limited during the sliding process, so as to avoid the two bearing pipes 2 approaching each other under the traction of the excavator and the traction steel rope 6, thereby affecting the construction support 1.

[0034] As a preferred embodiment, a connecting column 31 is provided on the top of the connecting plate 3, and the connecting column 31 is provided with at least a first pipe fastener 32, and the support pipe 5 is locked to the first pipe fastener 32. The first pipe fastener 32 can be a steel pipe fastener for construction in the prior art, which is convenient for disassembly and assembly. After the two bearing pipes 2 are passed through the bottom of the construction support 1, the two ends of the support pipe 5 can be locked to the connecting column 31 through the first pipe fastener 32, and when the displacement is completed, it can be disassembled.

[0035] As a preferred embodiment, the connecting column 31 is provided with a second pipe fastener 33, and the second pipe fastener 33 is used to connect with the longitudinal pipe 13 of the construction support 1. The construction support 1 is constructed by a horizontal pipe 11, a vertical pipe 12 and a longitudinal pipe 13. In order to make the construction support 1 more stable during the displacement process, the longitudinal pipe 13 of the construction support 1 close to the connecting column 31 can be locked with the connecting column 31 through the second pipe fastener 33, so as to prevent detachment or relative displacement during the sliding process, and avoid accidents such as collapse.

[0036] As a preferred embodiment, the support tube 5 is provided with a plurality of third tube fasteners 34, which are used to connect with the vertical tube 12 or the longitudinal tube 13 of the construction support 1. By providing a plurality of third tube fasteners 34 on the support tube 5, since the support tube 5 is horizontal, in order to further improve the overall stability, the plurality of vertical tubes 12 or longitudinal tubes 13 of the construction support 1 close to the support tube 5 are locked with the support tube 5 by the plurality of third tube fasteners 34, thereby increasing the connection stability between the construction support 1 and the traction device, and making the sliding process more stable.

[0037] As a preferred embodiment, a stopper is provided at one end of the supporting tube 2 away from the connecting plate 3. The stopper may be a baffle or a block, and is used to limit the construction support 1 at the other end of the supporting tube 2. The stopper may be detachably connected to the supporting tube 2, or may be fixedly connected, and its height only needs to be slightly higher than the horizontal tube 11 at the bottom of the construction support 1.

[0038] As a preferred embodiment, the connecting plate 3 is provided with a traction hole 35, and the traction member 4 is movably inserted into the traction hole 35. Since the two supporting tubes 2 are inserted into the bottom of the construction support 1 at a certain distance during sliding, and are connected to the traction machine located at the center line position thereof through the traction steel rope 6, the traction member 4 is movably inserted into the traction hole 35, so that the traction member 4 can rotate freely under the pulling force of the traction steel rope 6, making the traction more flexible and avoiding the traction steel rope 6 from being easily broken due to uneven force.

[0039] Specifically, the traction member 4 is a shackle, which has a stable connection and is easy to assemble and disassemble. It can be buckled into the traction hole 35 during installation and can be quickly removed during disassembly, which is easy to operate.

[0040] As a preferred implementation, in order to reduce the frictional resistance between the supporting tube 2 and the cement floor, one end of the supporting tube 2 close to the connecting plate 3 is cut obliquely so that its end face forms an obtuse angle with the bottom edge of the supporting tube 2 .

[0041] As a preferred implementation, in order to enhance the structural strength of the supporting tube 2 and the connecting plate 3, a horizontal notch 21 is opened at the top of one end of the supporting tube 2 close to the connecting plate 3, and the connecting plate 3 is welded to the horizontal notch 21 to increase the welding area and improve the strength.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
