Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to an assembly structure for protective components used in building construction. Background Technology

[0002] Building construction, or residential building construction, is an important branch of civil engineering. It refers to construction projects centered on buildings, encompassing the entire process of planning, design, construction, acceptance, and maintenance. Its core objective is to construct buildings that meet the needs of human habitation, office, commercial, or public activities, ensuring their safety, functionality, and durability. Elevator shaft construction is a crucial step in building construction. Before construction, precise measurements and layout are required to determine the location and dimensions of the elevator shaft. Next, formwork is erected, using high-quality formwork to ensure the flatness and verticality of the shaft walls. Reinforcement measures are implemented to prevent deformation. Reinforcing steel bars are tied strictly according to design requirements, ensuring accurate specifications, quantity, and spacing to enhance the structural strength of the shaft walls. During concrete pouring, the pouring height and speed must be carefully controlled to avoid segregation and other problems. Safety precautions are also essential during construction. Protective railings and safety nets are installed along the edges of the elevator shaft to prevent falls. Construction of each floor's elevator shaft is completed progressively as the building ascends.

[0003] During the construction of indoor elevator shaft openings in building construction projects, traditional protective structures often employ temporary protective railings erected with steel pipes and fasteners, or tool-type protective doors. In existing technologies, the fixing method generally relies on expansion bolts for anchoring the elevator shaft wall. However, this requires pre-drilling for the expansion bolts, which is cumbersome and causes structural damage to the elevator shaft wall. Subsequent repairs increase construction costs. Therefore, we provide an assembly structure for protective components used in building construction to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide an assembly structure for protective components used in building construction. By adjusting the cooperation of the components and the contact components, it solves the problem that the existing fixing methods generally rely on expansion bolts for anchoring elevator shaft walls. Expansion bolts require pre-positioning and drilling, which is cumbersome and causes structural damage to the elevator shaft walls, and subsequent repairs increase construction costs.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to an assembly structure for protective components used in building construction, including an elevator shaft wall. A retaining plate is attached to the surface of the elevator shaft wall. A protective plate is provided on one side of the elevator shaft wall. An adjustment assembly is provided on one side of the elevator shaft wall. The adjustment assembly includes a fixed rod on one side of the elevator shaft wall, an adjusting bolt fixedly connected to one end of the fixed rod, an adjusting plate threadedly connected to the surface of the adjusting bolt, and a tightening nut threadedly connected to the surface of the adjusting bolt. A contact assembly is provided inside the retaining plate. The contact assembly includes a worm gear movably connected to the inside of the retaining plate via a bearing, a worm wheel meshing with the surface of the worm gear, a threaded sleeve fixedly connected to the inside of the worm wheel, a screw threadedly connected to the inside of the threaded sleeve, and a contact plate movably connected to one end of the screw via a bearing.

[0007] The present invention is further configured such that the card plate is U-shaped, and the number of card plates is four, with two horizontal card plates forming a group.

[0008] The present invention is further configured such that the other end of the fixing rod is fixedly connected to the right side of the left side plate, and the other side of the adjusting plate is movably connected to the left side of the right side plate via a bearing.

[0009] The present invention is further configured such that the number of tightening nuts is four, two tightening nuts are threadedly connected to the surface of the adjusting bolt as a group, and the tightening nuts are arranged on both sides of the adjusting plate, and the tightening nuts are reverse nuts.

[0010] The present invention is further configured such that a mounting plate is fixedly connected to one side of both the fixing rod and the adjusting plate, and a mounting through hole is provided inside both the mounting plate and the protective plate, and a mounting bolt is provided inside the mounting through hole.

[0011] The present invention is further configured such that a rotating block is fixedly connected to one end of the worm gear, and a sealed bearing is fixedly connected inside the clamping plate. There are two sealed bearings, and the two sealed bearings are respectively located on one side of the worm wheel and the threaded sleeve. The worm wheel is fixedly connected to the inner ring of the right sealed bearing, and the threaded sleeve is fixedly connected to the inner ring of the left sealed bearing.

[0012] The present invention is further configured such that a limiting rod is fixedly connected to one side of the contact plate, and a limiting through hole adapted to the limiting rod is provided inside the card plate, and the limiting rod is located inside the limiting through hole.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model eliminates the traditional method of drilling with expansion bolts by adjusting the threaded transmission of the components and the reverse nut locking mechanism. It directly uses the clamping plate to contact and fix with the elevator shaft wall. Adjusting the bolt drives the spacing between the left and right clamping plates, and tightening the nut in the reverse direction quickly locks the position, improving construction efficiency. It does not require damaging the wall structure and avoids later repair costs. At the same time, the modular design supports repeated disassembly and assembly, significantly reducing material waste. It is especially suitable for the rapid deployment of elevator shaft protection in multi-story high-rise buildings.

[0015] 2. This utility model uses a worm gear transmission and screw linkage mechanism in the contact component to drive the contact plate to press evenly against the wall surface by rotating the worm. The self-locking characteristic of the worm gear prevents loosening caused by construction vibration. The limit rod constrains the linear movement of the contact plate. Combined with the sealed bearing, friction loss is reduced, ensuring uniform distribution of the pressing force and avoiding the stress concentration problem of traditional single-point fixing.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The worm wheel 9 and worm 8 transmission has a reverse self-locking characteristic to prevent the contact plate 12 from retracting due to construction vibration or external force.

[0027] Example 2

[0028] Please see Figures 1-5Based on Example 1, the clamping plate 2 is U-shaped, and there are four clamping plates 2 in total. Two horizontal clamping plates 2 form a group. By setting the U-shaped clamping plates 2, it is easy to clamp onto the elevator shaft wall 1. The other end of the fixing rod 4 is fixedly connected to the right side of the left clamping plate 2. The other side of the adjusting plate 6 is movably connected to the left side of the right clamping plate 2 through a bearing. The fixing rod 4 and the adjusting plate 6 are used to adjust the distance between the left and right clamping plates 2. There are four tightening nuts 7 in total. Two tightening nuts 7 form a group and are threadedly connected to the surface of the adjusting bolt 5. The tightening nuts 7 are set on both sides of the adjusting plate 6.

[0030] Then, the worm 8 is rotated by the rotating block 14. The worm 8 drives the worm wheel 9 to rotate, and the worm wheel 9 drives the screw sleeve 10 to rotate. The internal thread inside the screw sleeve 10 cooperates with the external thread on the surface of the screw 11, pushing the screw 11 to rotate and move. The screw 11 pushes the contact plate 12 to move towards the elevator shaft wall 1, so that the contact plate 12 contacts the elevator shaft wall 1. Through the self-locking of the worm 8 and the worm wheel 9, it can prevent the contact plate 12 from sliding again after adjusting its position. Finally, the protective plate 3 is fixedly connected to the mounting plate 13 by bolts, thus completing the installation of the elevator shaft opening protective component.
