A mobile integrated pipe gallery inner formwork

Abstract

The present invention relates to the field of building formwork, and in particular to a mobile integrated pipe gallery inner formwork, comprising: a base, universal wheels arranged at the bottom of the base, a truss fixedly arranged on the base, an upper formwork fixedly connected to the truss, two corner formworks hinged to both sides of the upper formwork, two side formworks fixedly connected to the bottom of the corner formwork, and an opening and closing mechanism arranged between the two side formworks. The universal wheels are used for the free movement of the inner formwork, and the angles between the corner formworks and the side formworks and the upper formworks can be changed through the opening and closing mechanism, so as to complete the positioning of the inner formwork and the guide wall. Compared with the installation of scaffolding, the operation is simple and the precision is high. When the formwork needs to be dismantled, the opening and closing mechanism can also separate the side formworks and the corner formworks from the side wall of the pipe gallery, thereby improving the dismantling efficiency.

Description

Technical Field

[0001] The invention relates to the field of building formwork, and in particular to a mobile integrated pipe gallery inner formwork. Background Art

[0002] The underground comprehensive pipeline corridor project is an important infrastructure project related to the national economy and people's livelihood. The current pipeline corridor structure construction is divided into two steps: base plate construction and main body construction. First, the base plate and guide wall of the pipeline corridor are cast through the base plate and guide wall templates, and then the upper main body is cast through the main formwork. Since the casting is completed in two steps, ensuring the positioning of the two castings becomes an important factor affecting the quality of the pipeline corridor. The main formwork in the existing technology is mostly positioned and installed by scaffolding, and its accuracy is poor, and it is easy to accumulate errors and cause concrete leakage. In addition, the formwork needs to be removed after the casting is completed. The formwork removal operation in the existing technology is complicated and the removal efficiency is low. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a mobile integrated pipe gallery inner formwork.

[0004] The present invention is achieved through the following technical solutions:

[0005] A mobile integrated pipe gallery inner formwork, characterized in that it comprises: a base, a universal wheel arranged at the bottom of the base, a truss fixed on the base, an upper formwork fixed on the truss, two corner formworks hinged to both sides of the upper formwork, two side formworks fixed to the bottom of the corner formworks, and an opening and closing mechanism arranged between the two side formworks.

[0006] The opening and closing mechanism includes two connecting rods hinged by a hinge shaft, a locking sleeve mounted on one of the connecting rods and sliding along the connecting rod, a sliding sleeve mounted on the other connecting rod, and a lifting mechanism fixed on the base. The two connecting rods are hinged to the two side templates one by one, respectively. The locking sleeve is provided with a locking groove for inserting the hinge shaft, and the free end of the lifting mechanism is hinged to the sliding sleeve.

[0007] Preferably, a limiting plate is fixedly connected to the inner wall of the side formwork, and a pulley abutting against the guide wall is provided on the limiting plate.

[0008] Preferably, the bottom of the connection between the corner template and the upper template is provided with a concession chamfer.

[0009] Preferably, the lifting mechanism is a jack.

[0010] Preferably, a spring is provided between the locking sleeve and the connecting rod.

[0011] The beneficial effects of the present invention are:

[0012] The universal wheels are used for the free movement of the inner formwork. The opening and closing mechanism can change the angle between the corner formwork and the side formwork and the upper formwork, thereby completing the positioning of the inner formwork and the guide wall. Compared with the scaffolding installation, its operation is simple and the precision is high. When the formwork needs to be dismantled, the opening and closing mechanism can also separate the side formwork and the corner formwork from the side wall of the corridor, thereby improving the dismantling efficiency.

[0015] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and the best embodiments.

[0016] As shown in the figure, the present invention relates to a mobile integrated pipe gallery inner formwork, comprising a base, a universal wheel arranged at the bottom of the base, a truss fixed on the base, an upper formwork fixed on the truss, two corner formworks hinged on both sides of the upper formwork, two side formworks fixed to the bottom of the corner formwork, and an opening and closing mechanism arranged between the two side formworks, wherein the opening and closing mechanism is used to control the opening or folding of the corner formwork and the side formwork.

[0017] The opening and closing mechanism includes two connecting rods hinged by a hinge shaft, a locking sleeve mounted on one of the connecting rods and sliding along the connecting rod, a sliding sleeve mounted on the other connecting rod and a lifting mechanism fixed on the base, the two connecting rods are hinged to the two side templates one by one, the locking sleeve is provided with a locking groove for the hinge shaft to be inserted, a spring is provided between the locking sleeve and the connecting rod, the free end of the lifting mechanism is hinged to the sliding sleeve, and the lifting mechanism in this embodiment is a jack. When in use, the inner mold frame is first transported to the bottom plate through the universal wheel, the jack is started to drive the sliding sleeve so that the two connecting rods are in the same straight line, the spring can make the locking sleeve move toward the hinge shaft so that the hinge shaft is inserted into the locking groove, at this time the two connecting rods will not be able to continue to rotate, and the mold frame is opened. After the casting is completed and the hardness requirement is met, the locking sleeve is pulled to make the hinge shaft slide out of the locking groove, the jack is started in the reverse direction, the two connecting rods are rotated, the corner template and the side template can be folded inward, and the mold frame is removed.

[0018] Preferably, a limiting plate is fixedly connected to the inner wall of the side formwork, and a pulley abutting against the guide wall is provided on the limiting plate. The limiting plate can play a role of limiting and positioning to prevent misalignment between the side formwork and the guide wall.

[0019] Preferably, the bottom of the connection between the corner template and the upper template is provided with a yield chamfer to provide space for the upper template and the corner template to flip.

[0020] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have 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.
