Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an integrated structure for demoulding and maintaining a railway bridge pier. Background Art

[0002] In the construction of thin-walled hollow piers in bridge projects, the segmented formwork method is often used, that is, after the concrete is poured, the formwork is removed layer by layer from bottom to top, and a section of the formwork is reserved on the upper part as the bearing layer to install the second section of the pier formwork. However, each section of the formwork is fixed with bolts. When dismantling the formwork, the bolts need to be removed manually. Usually, the industry generally uses lifting equipment to lift the cage to provide an operating platform for the formwork removal workers. This method has serious safety hazards.

[0018] Legend: 1. Bridge pier; 2. Operating platform; 3. Hand hoist; 4. Casting formwork. DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] See also Figure 1 A railway bridge pier body mold removal and maintenance integrated structure is arranged on the casting formwork, and the integrated structure includes: a hanging block fixedly installed on the casting formwork; a hand winch 3 arranged on the hanging block; and an operating platform 4 fixedly installed on the hand winch 3 and arranged along the outer periphery of the bridge pier body, and the operating platform 4 is lifted by pulling the hand winch 3.

[0021] In the present invention, a preferred embodiment is as follows: a plurality of casting templates 4 are arranged on the foundation, concrete is poured into the casting templates 4 to form the bridge pier 1, after the concrete solidifies, the casting templates 4 at the bottom are removed, and the removed casting templates 4 are arranged on the casting templates 4 at the top, and concrete is continuously poured into the casting templates 4, while waiting for the concrete to solidify, an operating platform 2 is arranged below the casting templates 4, and a hand chain hoist 3 is arranged between the operating platform 2 and the topmost casting template 4, so that construction workers can operate the bridge by pulling the hand chain hoist 3. The cast-completed part of the beam pier body 1 is maintained, and after the concrete in the casting formwork 4 solidifies, the hand winch 3 is pulled to make the operating platform 2 rise and approach the bottom casting formwork 4, and the construction personnel can stand on the operating platform 2 to dismantle the bottom casting formwork 4, and install the dismantled casting formwork 4 above the top casting formwork 4. Preferably, when the hand winch pulls the operating platform 2 to the casting formwork 4 installed with the hand winch 3, the construction personnel can hang the hand winch 3 on the higher casting formwork 4 to facilitate subsequent construction.

[0022] Furthermore, a spray device is provided at the bottom of the operating platform 2. The spray system can facilitate construction workers to maintain the poured concrete.

[0023] Furthermore, a fence is provided on the top of the operating platform 2. The fence can ensure the personal safety of construction workers.

[0024] Furthermore, the hand chain hoist 3 is provided in plurality. By pulling the plurality of hand chain hoists 3 at the same time, the operating platform 2 can be raised more steadily. When the hand chain hoists 3 are arranged on the pouring platform at a higher position, the construction workers can remove the hand chain hoists 3 one by one and re-hang them on the pouring formwork 4 at a higher position.

[0025] Furthermore, the hanging block is formed with a through hole corresponding to the hand chain hoist 3, and the hand chain hoist 3 passes through the through hole. The through hole can ensure that the hand chain hoist 3 is fixed more firmly.

[0026] Furthermore, a fixing block is formed on the top of the operating platform 2 corresponding to the hand chain hoist 3, and the hand chain hoist 3 is fixedly mounted on the fixing block. The fixing block can make the hand chain hoist 3 more firmly fixed.

[0027] Furthermore, the disassembled casting formwork is installed on the top of the topmost casting formwork through a car crane.

[0028] Furthermore, a penetration space is formed in the operating platform 2, and the size of the penetration space is adapted to the size of the casting template 4. Preferably, the bridge pier 1 formed after casting is penetrated in the penetration space, and the operating platform 2 is arranged around the casting template 4, so that construction workers can more conveniently remove the casting template 4 around the bridge pier 1.

[0029] The following is an explanation of the use process of the integrated structure for demoulding and maintaining the pier of a railway bridge according to the utility model.

[0030] Now, multiple casting templates 4 are set on the foundation, and concrete is poured into the casting templates 4 to form the bridge pier 1. After the concrete solidifies, the casting template 4 at the bottom is removed, and the removed casting template 4 is set on the casting template 4 at the top, and concrete is continued to be poured in the casting template 4. While waiting for the concrete to solidify, an operating platform 2 is set below the casting template 4, and a hand winch 3 is set between the operating platform 2 and the top casting template 4. By pulling the hand winch 3, the construction workers can cast the bridge pier 1. Partial maintenance is carried out, and after the concrete in the casting formwork 4 is solidified, the hand winch 3 is pulled to make the operating platform 2 rise and approach the bottom of the casting formwork 4, and the construction personnel can stand on the operating platform 2 to dismantle the bottom casting formwork 4, and install the dismantled casting formwork 4 above the top casting formwork 4. Preferably, when the hand winch pulls the operating platform 2 to the casting formwork 4 installed with the hand winch 3, the construction personnel can hang the hand winch 3 on the higher casting formwork 4 to facilitate subsequent construction.
