Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of pile foundation construction, and particularly relates to a pile foundation reinforcement cage temporary fixing device with buckles. BACKGROUND

[0002] With the development demand of the building industry and transportation in China, more and more deep hole pile foundations need to be constructed. The deep hole pile foundation is affected by the manufacture, transportation, hoisting and surrounding environment of the reinforcement cage, resulting in the need for segmented assembly of the deep hole pile foundation reinforcement cage. The reinforcement cage that has been lowered into the hole needs to be temporarily fixed during the reinforcement cage assembly. After the upper and lower segments of the reinforcement cage are connected, the lower reinforcement cage is continued to be lowered until the design requirement depth is reached.

[0003] In the prior art, two thick steel pipes are usually used to connect the upper and lower segments of the reinforcement cage. The two ends of the steel pipes cross the reinforcement cage and are supported on the casing. If the geology under the casing is poor, a support pad needs to be added outside the steel pipe to support the steel pipe. This method is not convenient to operate. Because the reinforcement cage is heavy, the casing is easily pressed into the ground. In addition, the steel pipe is easily deformed under the action of the reinforcement cage, and there is a risk of the reinforcement cage falling into the hole. There is also a method of using a solid steel rod. However, the solid steel rod is heavy, and when a large-diameter pile foundation is encountered, multiple people are needed to install and remove it. There is a risk of the steel rod falling into the hole, and there are problems of inconvenience and low efficiency in construction. Although some reinforcement cage fixing devices exist in the prior art, they do not have buckle devices. The telescopic arm slides during the construction process, resulting in problems such as the reinforcement cage falling and tilting. Therefore, there is an urgent need to design a temporary fixing device with buckles for fixing the pile foundation reinforcement cage. UTILITY MODEL CONTENTS

[0010] Further, the triangular platform reinforcing steel plate on the top of the I-shaped steel girder is provided with an lifting lug.

[0011] Compared with the prior art, the device has the following beneficial effects:

[0012] In the steel reinforcement cage connection construction process, the sawtooth-shaped clamping groove on the buckle baffle and the telescopic arm is matched to avoid the telescopic arm retraction sliding phenomenon in the construction process,

[0013] The telescopic arm can ensure that the telescopic arm extension length is not shortened and will not slide, so that the steel reinforcement cage that has entered the hole will not fall, skew and other problems, and the steel reinforcement cage connection is more secure.
