Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular discloses a prefabricated component template system for a highway or municipal assembled tunnel. Background Art

[0002] Highway or municipal tunnel walls often feature slotted chambers, primarily reserved for tunnel fans, lighting distribution boxes, tunnel inspection boxes, area controllers, emergency telephone boxes, UPS distribution boxes, cameras, and fire power supply and fire cabinets. Large prefabricated components produced using standardized components have uniform specifications and shapes. Each component, containing different chambers, is individually manufactured. The reserved chambers are precisely positioned and secured with additional formwork manually during the reinforcement binding phase. The internal joints between the additional formwork and the component formwork are covered with transparent tape or double-sided tape is applied inside the joints. Repeated use of wooden formwork makes this method less effective in preventing grout leakage, and the component's appearance quality is difficult to guarantee. Constant replacement of wooden formwork wastes resources and increases construction waste, which is inconsistent with the concept of green construction.

[0003] Therefore, it is necessary to design a flexible and adjustable large-scale prefabricated component formwork system that does not affect standardized production, but can facilitate the production of various reserved caverns, ensure the appearance quality of the components, highly utilize production resources, and achieve green production. Summary of the Invention

[0004] The present invention aims to provide a prefabricated component template system for highway or municipal assembled tunnels, which can meet the needs of various reserved caverns while ensuring standardized production of prefabricated components.

[0005] In order to achieve the above object, the basic scheme of the present invention is:

[0006] A prefabricated component formwork system for a highway or municipal assembled tunnel comprises a bottom formwork and side forms arranged on both sides of the bottom formwork; the bottom formwork comprises a base frame and a bottom formwork steel plate, a moving device is provided at the bottom of the base frame, a plurality of columns are fixed to the top of the base frame, and the tops of the columns are fixedly connected to the bottom formwork steel plate; a support frame is fixed between the columns, and a side formwork track beam is provided on the support frame; the bottom of the side formwork is slidably connected to the side formwork track beam, and the side formwork and the bottom formwork steel plate are detachably connected; end forms are detachably connected at both ends of the bottom formwork steel plate, the bottom formwork steel plate comprises a plurality of sections of foundation formwork, and connecting formworks are detachably connected between adjacent foundation formworks, and some connecting formworks are provided with raised cavern formworks.

[0007] In this solution, the bottom formwork is moved to the pouring area by means of mobile equipment. If there is no cavern, an ordinary connecting formwork is installed on the base formwork. If there is a cavern, the connecting formwork that drives the cavern formwork is installed on the base formwork, the side formwork track beam is fixed on the support frame, and then the side formwork is hoisted onto the side formwork track beam, and the side formwork is slid so that the side formwork is connected and fixed to the bottom formwork steel plate, and then pouring can be carried out. By replacing the ordinary connecting formwork with the connecting formwork that drives the cavern formwork, it can be applied to tunnel pouring with and without caverns, ensuring the standardized production of prefabricated components while meeting the needs of various reserved caverns. The formwork structure is simple, the construction operation is convenient, and it conforms to the concept of green standardized production.

[0008] Optionally, auxiliary support rods are provided on both the connection template and the cavern template, and the auxiliary support rods are detachably connected to the support frame.

[0009] Optionally, grooves are provided on the facing ends of the base template, protrusions are fixed at both ends of the connecting template, and the protrusions are connected to the grooves by bolts.

[0010] Optionally, the side form includes a side form panel, which has vertical reinforcement ribs and transverse reinforcement ribs built into the side form panel. A connecting support rod is fixed on the side form panel, and the connecting support rod is slidably connected to the side form rail beam through a movable roller.

[0011] Optionally, a plurality of tie rods are provided on both sides of the base formwork and the connecting formwork, and tie rod reserved holes are provided on the side formwork panel.

[0012] Optionally, limit plates are provided at both ends of the side form rail beam.

[0013] Optionally, concrete columns for supporting the side formwork track beams are provided on the ground.

[0014] Material toggling mechanism, its both ends are connected with the up-down knob.The knob has the shape of a hole, and the button has a button bar, and the button bar has a hook. The button bar is connected with the up-down knob. The button bar is connected with the hook at two ends. The two button bars are connected with the hook at two ends. The two button bars are connected with the hook at two ends.

[0015] In this solution, due to the squeezing of concrete, the bottom form steel plate is concave. By moving the base, the adjusting device is placed under the concave area. By rotating the base, the base is made parallel to the concave area and the center of the bottom form steel plate. At this time, the telescopic end of the second limiting cylinder is disengaged from the limiting hole. When the connecting frame is driven upward by the telescopic cylinder, the movement of the connecting frame drives the support plate upward until the positioning rod on the support plate is against the remaining undeformed area of ​​the bottom form steel plate, thereby squeezing the support plate downward. When all the support plates have moved downward, the telescopic cylinder is closed and the second limiting cylinder is started. The telescopic end of the second limiting cylinder is inserted into the limiting hole to fix the support plate. At this time, the top composition of the support plate is the same as The bottom mold steel plate has an arc surface with the same arc; then, all the support plates are driven upward by the telescopic cylinder and the connecting frame to lift the recessed area of ​​the bottom mold steel plate until the support plate and the bottom mold steel plate are fitted together. Since the top of the support plate is composed of an arc surface with the same arc as the bottom mold steel plate, the curvature of the bottom mold steel plate after the support plate is lifted is the same as the original curvature, and will not cause deformation of the recessed area after lifting. In addition, this device can also be used to restore the recesses of bottom mold steel plates of various specifications, which greatly improves the applicability of the device; during the lifting process of the support plate, the first limit cylinder is started to disengage the telescopic end of the first limit cylinder from the positioning hole, so that the positioning rod can slide in the slide groove, thereby avoiding obstruction to the lifting of the support plate.

[0016] Optionally, rotating shafts are fixed at both ends of the base, and the rotating shafts pass through the adjustment seat and are rotatably connected thereto. An annular block is fixed around the rotating shaft, and the annular block is detachably connected to the adjustment seat by bolts.

[0017] When the base needs to be adjusted, the bolts are removed and the annular block and the rotating shaft can rotate freely with the base; when the base needs to be locked, the annular block is fixed to the adjustment seat with bolts to lock the base to prevent the base from rotating during the restoration process of the bottom mold steel plate.

[0018] Other advantages, objects, and features of the present invention will be described in part in the following description and, in part, will be apparent to those skilled in the art upon examination of the following description or may be learned from practice of the present invention. The objects and other advantages of the present invention may be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS
