Description

Technical Field

[0001] The present invention relates to the technical field of installation of protective sealed doors for construction projects and civil air defense projects, and in particular to a multi-section adjustable protective sealed door precision positioning installer and a use method thereof. Background Art

[0002] Civil air defense projects are the most important hidden places for urban residents to defend against air attacks during wartime. During the construction of protective closed doors for civil air defense projects, the existing door frame installation method mainly relies on manual lifting and prying due to the high cost and difficulty of access to large equipment, as well as the conflict between the protective doors and the main structures of each basement during cross-construction. However, due to the lack of attention, the limitations of manual operation, and the complexity of related nodes, this method has the following problems during the construction process:

[0003] (1) The existing installation and positioning method of protective doors is prone to conflict with the building structure. In particular, the protective door frame is prone to causing varying degrees of damage to the basement floor and wall steel bars during the process of tilting and then erecting. The steel bars are also prone to skew and deformation during the application of installation forces.

[0004] (2) The existing installation method is inconvenient to operate during the installation of the civil air defense door, and the work efficiency is low. During the construction process, it is impossible to dynamically detect and adjust the horizontality, verticality, and inclination of the protective door frame. In addition, the subsequent formwork and concrete engineering construction process may cause certain disturbances to the protective door frame, thereby causing displacement. The inconvenience of adjustment makes it impossible to correct the door installation accuracy after the pouring is completed;

[0005] (3) During the installation operation, due to the different sizes of different protective doors, operators generally use mobile scaffolding, ladders, etc. to apply installation force. During this process, operators often have low installation accuracy of protective door frames due to improper operation, and certain safety hazards arise during the construction process due to improper wearing of protective equipment, such as scratches and falls on steel bars and binding wire corners. Summary of the Invention

[0006] The purpose of the present invention is to provide a multi-stage adjustable protective closed door precise positioning installer and a method of use, so as to solve the problem of inconvenience in installation and adjustment of the protective door frame.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a multi-section adjustable protective airtight door precision positioning installer, comprising at least two sets of parallel telescopic adjustment devices and an auxiliary load-bearing measuring instrument; wherein the telescopic adjustment device comprises a boss for binding or welding fixation, a threaded hole is provided on the upper end thereof and a connecting rod is fixedly installed, the upper part of the connecting rod is detachably connected to one end of a connecting pipe, the other end of the connecting pipe is open, an adjusting rod is inserted into the interior thereof, a plurality of through holes are provided from one end to the middle of the adjusting rod located inside the connecting pipe, and a plurality of holes parallel to the through holes are provided on the connecting pipe. It is used for bolts to pass through for positioning, and the adjusting rod is located on the outside of the connecting pipe and is provided with an external thread and is threadedly connected to a fine-tuning nut. A limit plate is fixed on the side away from the connecting pipe, and a force transmission sleeve is sleeved on the adjusting rod, one end of which is placed on the limit plate, and the other end is detachably fixedly connected to a support rod, and the end away from the force transmission sleeve is movably connected to the door frame through a hole at the upper end of the door frame; the auxiliary load-bearing measuring instrument includes a telescopic connecting piece and a follow-up measuring end, wherein the follow-up measuring end is fixed on one side of the door frame, and a level bubble is fixed on it, and the two ends of the telescopic connecting piece are movably connected to the force transmission sleeve and the follow-up measuring end respectively.

[0008] Preferably, an ear plate is welded to one side of the force transmission sleeve, and the telescopic connecting piece consists of a cylinder body and a piston rod slidably connected thereto. The bottom end of the cylinder body is fixed with a cylinder body hinge end, which is hinged to the ear plate, and the top end of the piston rod is fixed with a piston rod hinge end. The follow-up measuring end includes a vertical connecting plate, the piston rod hinge end is hinged to the middle part of one side of the connecting plate, and a bottom plate is fixed on the other side of the connecting plate, and a magnet is fixed on the side away from the connecting plate for adsorption on the door frame.

[0009] Preferably, the vial includes a horizontal vial and a vertical vial. The horizontal vial is parallel to the magnet and is horizontally fixed or embedded in the base plate, and the vertical vial is perpendicular to the magnet and is fixed or embedded in the connecting plate.

[0010] Preferably, the boss and the basement floor slab are tied or welded at the overlap position of the double-layer bidirectional steel bars.

[0011] Preferably, a connecting sleeve is sleeved on one end of the force transmission sleeve away from the connecting pipe, the support rod is inserted into the connecting sleeve, and a plurality of pins vertically pass through the force transmission sleeve, the connecting sleeve and the support rod.

[0012] Preferably, the telescopic adjustment device also includes a fixing part, which is fixedly connected to the upper end of the door frame, and a support rod hinge end is provided at the end of the support rod away from the connecting tube, and a fixing part hinge end is provided on the fixing part, and the support rod hinge end is hinged to the fixing part hinge end.

[0013] Another technical solution provided by the present invention is a method for using the above-mentioned installer, comprising the following steps:

[0014] Step 1: Based on the width and position of the door frame to be installed, measure the vertical frame edges on both sides of the door frame to the overlap position of the double-layer bidirectional steel bars of the basement floor and mark them on the corresponding steel bars. Tie or weld the bosses of the two sets of telescopic adjustment devices to the two marked positions respectively, and remove all bolts.

[0015] Step 2: Move the door frame to the location where it is to be installed and align its bottom edge with the bottom surface where it is to be installed. Install the removable fixings at the holes at the upper end of the door frame. Manually move or pry up the top of the door frame to a certain height, tilt the installer and hinge the upper end of the support rod to the hinged end of the fixing.

[0016] Step 3: Fix the magnets of the two sets of auxiliary load-bearing measuring instruments on both sides of the door frame respectively, and push the adjusting rod or door frame toward the installation position. When pushing the door frame, the adjusting rod should be gradually withdrawn from the connecting pipe to ensure that the force transmission sleeve does not separate from the limit plate; after visually observing that the door frame is upright or nearly upright, fix the adjusting rod to the connecting pipe with bolts;

[0017] Step 4: Observe the horizontal and vertical vials of the two sets of auxiliary load-bearing measuring instruments, and rotate the fine-tuning nuts of the two sets of telescopic adjustment devices until all the bubbles are in the middle position;

[0018] Step five: fix the formwork and pour in-situ reinforced concrete around the door frame. Repeat step four after pouring. After the strength of the in-situ reinforced concrete reaches the standard, disconnect the connection between the fixings and the door frame, and between the connecting pipe and the connecting rod. Then, remove the installer and install the protective airtight door on the door frame.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The precise positioning installer and usage method of the multi-section adjustable protective closed door can lift the protective door frame to a certain height without prying or pressing. This can greatly reduce the contact between the protective door and the structural steel skeleton during the load-applying and lifting process, and effectively reduce the damage to the formed steel bars caused by traditional prying and pressing construction methods.

[0021] 2. The multi-stage adjustable protective closed door precision positioning installer and usage method can adjust the positioning of the door frame during the jacking process through the two stages of adjusting rod and fine-tuning nut. During the jacking period, the horizontality and verticality of the protective door frame can be synchronously monitored in conjunction with the measuring instrument. The positioning is dynamically adjusted by observing the position of the spirit level until the horizontality and verticality of the door frame installation meet the quality requirements. In the later formwork and concrete construction processes, the disturbance of the installed door frame can be dynamically monitored by the position change of the spirit level on the mainboard of the measuring instrument. After the structural formwork and concrete pouring around the door frame are completed and before the initial solidification and hardening, the installation size deviation can still be adjusted in time by rotating the fine-tuning nut, effectively realizing the dynamic monitoring and synchronous adjustment of the construction accuracy of the entire door frame installation process, providing favorable preconditions for the subsequent door leaf installation, improving the overall construction quality of the civil air defense protective door, and building a solid safety line.

[0022] 3. The multi-section adjustable protective closed door precise positioning installer and usage method, through the semi-rigid and rigid connection of multiple sections of rods, replaces the traditional load application that requires the help of an operating platform or scaffolding. The overall operation is more flexible and simple, and the components are more versatile and flexible. The instrument can be disassembled and used in rotation. While improving work efficiency, the instrument itself can also serve as a temporary support for the protective door frame, ensuring the safety of personnel during the construction process.

[0023] 4. The multi-section adjustable protective closed door precise positioning installer and usage method, the installer boss can determine the layout point according to the height, positioning and actual construction needs of the protective door frame, locate the installation position of the protective door, and connect it to the double-layer bidirectional steel mesh of the basement floor by binding or welding. The boss can also be used as a reinforcement foot for the steel bars between the upper and lower layers of steel mesh to avoid the skew deformation of the steel bars under the action of construction loads, improve the construction quality of concrete projects, and reduce the safety hazards of workers walking on the steel mesh surface due to the excessive thickness of the bottom plate and the large spacing between the steel meshes.

[0024] 5. The multi-section adjustable protective closed door precise positioning installer and usage method are easy to operate, safe, flexible, and reusable. They are suitable for the precise positioning, installation, and dynamic adjustment of various protective closed doors. During the process, they can also serve as temporary support, solving the conflicts between a series of protective doors and the main structures of each basement during cross-construction, ensuring the positioning and installation accuracy of important architectural functions and structural components of civil air defense facilities in wartime, thereby improving the overall construction quality of civil air defense projects, reducing the risk of rework and waste of resources, avoiding functional safety issues and common quality problems, building a solid national defense lifeline, and achieving significant economic benefits.
