Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, especially relates to a construction bench for external wall thermal insulation. BACKGROUND

[0002] In the modern construction industry, external wall thermal insulation, as a key energy-saving and protective measure, is widely used in various buildings. Its main purpose is to protect the external wall surface and the main structure of the building, and to reduce the direct damage of the external environment (such as temperature change, wind and rain erosion, etc.) to the building. By adding thermal insulation materials to the surface of the external wall, the external temperature can be effectively insulated, and the heat transfer can be reduced, thereby improving the energy utilization efficiency of the building and reducing the indoor temperature fluctuation, providing a more comfortable environment for the occupants.

[0003] When laying external wall thermal insulation materials on high-rise buildings, the construction position is at a high altitude, and the construction difficulty and risk are high. At present, a high-altitude suspended construction bench is usually used, and the construction personnel perform construction operations on the bench. The common external wall thermal insulation construction bench mainly consists of a bench plate and an edge barrier plate, and this bench structure is simple and can meet the basic construction requirements.

[0004] However, with the continuous development of building construction technology and the increasing requirements for construction efficiency and safety, some disadvantages of the traditional construction bench have gradually emerged. According to the search, Chinese patent publication No. CN221941883U discloses an external wall thermal insulation construction bench, which drives the placement box to move up and down through the cooperation of the conveying device, the driving motor and the connecting belt, so that the thermal insulation materials can be conveyed to the construction bench, which facilitates the continuous construction work of workers, saves work time and improves work efficiency. However, in actual use, the construction bench has obvious defects: when the thermal insulation materials are conveyed upward through the placement box lifting, only the flexible connecting belt is used as the limiting connecting piece outside the placement box. Due to the flexible characteristics of the connecting belt, the placement box is easily shaken in the air during the lifting process due to factors such as wind force and uneven distribution of materials in the placement box. Once the placement box shakes, it is difficult to directly align with the inside of the fixed sleeve accurately, which leads to the risk of collision between the placement box and the bottom of the bench during the lifting process. Such collision not only damages the placement box and the bench structure, affecting the service life of the bench, but also may cause the thermal insulation materials to scatter, posing a serious threat to the safety of the construction personnel. In addition, the traditional construction bench lacks effective arrangement and fixation measures for the materials during the placement and retrieval of the thermal insulation materials, and when the thermal insulation materials in the placement box are not placed regularly or are inclined, it is easy to hinder the smooth entry of the placement box into the fixed sleeve, further affecting the construction efficiency. Therefore, it is of great practical significance to develop a new type of external wall thermal insulation construction bench to solve the above-mentioned problems in the prior art. UTILITY MODEL CONTENTS

[0005] The utility model discloses a construction bench for external wall heat preservation, which solves the problem of collision between the heat preservation material and the bottom of the bench caused by shaking when the heat preservation material is lifted by the placing rack and the problem of tilting of the heat preservation material in the placing box to hinder feeding.

[0009] The size of the through groove is optimized according to the size of the placing box to ensure that the placing box can be smoothly moved to the bottom of the bottom plate through the through groove. The edges of the through groove are polished to remove sharp corners and avoid causing wear or damage to the placing box when the placing box passes through.

[0010] Preferably, the fixed shell is made of high-quality aluminum alloy material and is formed by high-precision die casting, which has the characteristics of light weight and high strength. The internal space of the fixed shell is carefully designed to tightly sleeve the placing box and provide all-round limiting protection for the placing box to ensure the stability of the placing box during movement.

[0011] Preferably, the placing box is integrally injection molded by high-strength engineering plastic, which has good toughness and wear resistance. The connecting belt is made of high-strength and wear-resistant polyester fiber material and is subjected to special weaving process treatment, which has very high tensile strength and flexibility.

[0012] Preferably, the width and thickness of the connecting belt are strictly calculated to ensure that no breakage or deformation occurs when bearing the weight of the placing box and the internal heat preservation material. Preferably, the surface of the connecting belt is further coated with an anti-skid coating layer to increase the friction with other components and prevent slipping during the winding and releasing processes.

[0013] In addition, the limiting cylinder is preferably made of high-strength polycarbonate material, which has good transparency and wear resistance. The inner wall of the limiting cylinder is polished to have extremely low surface roughness, which can reduce the friction between the connecting belt and the limiting cylinder while ensuring smooth movement of the connecting belt in the limiting cylinder.

The internal bottom surface of the placing box is provided with a moving groove, a screw rod is rotatably connected to the front inner wall surface of the moving groove, a moving block is threadedly connected to the outer side of the screw rod, and a push plate is fixedly connected to the upper surface of the moving block.

[0017] Preferably, the rear end of the screw rod penetrates through the placing box, and a connecting block is fixedly connected to the rear end of the screw rod and embedded in the rear surface of the placing box. The moving block is slidably connected with the inside of the moving groove.

[0018] Through the above design, the following beneficial technical effects can be achieved:

[0019] 1. Improve the stability and safety of the rack: by setting the connecting belt, winding unit, limiting cylinder, sliding groove, sliding block and limiting rod in cooperation, the movement of the placing box can be guided and limited in all directions. When the placing box moves to the bottom of the base plate, under the joint action of these components, the placing box can only stably move up and down in a straight line, and can stably enter the fixed shell to complete the feeding, effectively avoiding the shaking of the placing box at the bottom of the base plate to cause impact with the base plate. This not only improves the stability of the rack, prolongs the service life of the rack, but also greatly guarantees the safety of the workers and reduces the safety risk in the construction process.

[0020] 2. Ensure the smooth feeding of the thermal insulation material: by setting the cooperation of the moving groove, lead screw, moving block, push plate and connecting block, the thermal insulation material can be effectively extruded and limited in time when it is inclined in the placing box. The staff only needs to use the tool to twist the connecting block, drive the lead screw to rotate, and then drive the push plate to move forward under the cooperation and limitation of the moving block and the moving groove, extrude the inclined thermal insulation material back to the vertical state, avoid the obstruction of the placing box into the fixed shell to complete the feeding caused by the inclination, improve the construction efficiency, and reduce the material waste and delay in the construction process.

Since the screw rod 12 is threadedly connected with the moving block 13, and the moving block 13 is slidingly connected with the moving groove 11, during the rotation of the screw rod 12, the moving block 13 moves to the front side under the limitation of the moving groove 11. The moving block 13 drives the push plate 14 to move synchronously, the push plate 14 moves forward to extrude the heat preservation material, so that the heat preservation material remains in a vertical state, avoiding the offset to hinder the placing box 5 from entering the inside of the fixed shell 4. After the operation is completed, the worker checks the placement of the heat preservation material again, and continues to operate the placing box 5 to rise after ensuring that the material is stable.
