Description

Technical Field

[0001] This utility model relates to the field of building materials, and in particular to a device for reinforcing embedded parts. Background Technology

[0002] In the field of building construction, embedded parts serve as the basic components for the installation of various subsequent structures and equipment, and the stability and accuracy of their installation are of paramount importance.

[0003] Traditional methods of reinforcing embedded parts have many drawbacks. Common methods rely solely on simple spot welding or a small number of bolts for fixation. When faced with large building structures, complex stress conditions, and the impact and vibration forces during concrete pouring, embedded parts are prone to displacement, deformation, or even detachment. This not only hinders subsequent installation processes, requiring significant manpower and resources for rework and adjustment, but also serves as the standard for repositioning embedded parts, delaying the construction period and potentially affecting the stability and safety of the entire building structure.

[0004] Therefore, there is an urgent need to design a pre-embedded part reinforcement device to solve the problems of unstable fixing and inconvenient adjustment in the existing pre-embedded part fixing methods. Utility Model Content

[0005] The purpose of this utility model patent is to design a pre-embedded component reinforcement device through analysis, research and experimentation on the fixing and adjustment of pre-embedded components on site.

[0006] This utility model provides a pre-embedded component reinforcement device, including a casting space formed by a rectangular hollow template. The template is composed of wooden boards and square timbers linearly and evenly distributed on the inner side of the wooden boards. Four main support steel pipes are fixed to each other on the four outer periphery of the casting space. The four main support steel pipes are closely attached to the outer periphery of the template and are arranged in several groups along the longitudinal section of the template. Two sets of horizontal support steel pipes are fixed on the main support steel pipes above the casting space. Each set of horizontal support steel pipes consists of two pipes with a gap between them. Each set of two horizontal support steel pipes is equipped with tie bolt assemblies, which extend downward into the casting space. The pre-embedded component is installed between the lower ends of the two sets of tie bolt assemblies.

[0007] The main support steel pipes are seamless steel pipes with an outer diameter of 48-60mm and a wall thickness of 3-5mm, and are cut into sections of different lengths according to the actual layout and stress requirements of the construction site. The horizontal connecting steel pipes are steel pipes with an outer diameter of 32-42mm and a wall thickness of 2.5-4mm, which are vertically fixed to the main support steel pipes to form a stable grid structure; each section of steel pipe is fixed together by welding or fasteners.

[0008] Furthermore, the tie bolt assembly includes a bolt body made of 42CrMo steel with a nominal diameter of M16-M24 and a length of 300-800mm. Nuts and washers are provided at both ends of the bolt body; the bolt body is connected to angle steel via nuts, and embedded parts are fixedly installed between the angle steel of the two sets of tie bolt assemblies.

[0009] Furthermore, the bolt body is inserted into the gap between each group of two horizontal support steel pipes. The upper end of the bolt body is adjusted and fixed above the two horizontal support steel pipes by a nut. The angle steel is tightened and loosened to the lower end of the bolt body by a nut. Various special fixing angle steels are designed for embedded parts of different shapes, with angle steel models ranging from L50×5 to L75×8, and lengths adapted to the dimensions of the embedded parts. One end of the angle steel is welded to the embedded part using a full welding process to ensure connection strength; the other end is drilled with a hole diameter adapted to the diameter of the tie bolt, and is fixed to the tie bolt by a nut.

[0010] Furthermore, the nut is a wing nut, which allows the operator to rotate it by hand to quickly and finely adjust the tightness of the tie bolt, thereby adjusting the positional accuracy of the embedded part, with an adjustment range of ±5mm.

[0011] The beneficial effects of this invention are as follows:

[0012] This utility model's embedded part reinforcement device, through the fixed connection between the main support steel pipe and the horizontal support steel pipe, forms a stable grid-like structure around the outer periphery of the casting space formed by the template, ensuring the stability of the embedded part's casting. A tie bolt assembly is set on the horizontal support steel pipe, and the embedded part is fixed at the lower end of the tie bolt assembly by angle steel. The vertical distance of the bolt body extending downward into the casting space and its horizontal position on the horizontal support steel pipe are adjusted by the nut, thereby adjusting the positional accuracy of the embedded part.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings:

[0017] refer to Figures 1 to 2The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0018] This utility model provides a pre-embedded component reinforcement device, including a casting space 5 formed by a rectangular hollow template. The template is composed of wooden boards 8 and square timbers 7 linearly and evenly distributed on the inner side of the wooden boards 8. Four main support steel pipes 2 are fixed to each other on the four outer periphery of the casting space 5. The four main support steel pipes 2 are closely attached to the outer periphery of the template and are arranged in several groups along the extension direction of the template. Two sets of horizontal support steel pipes 3 are fixed on the main support steel pipes 2 above the casting space. Each set of horizontal support steel pipes 3 consists of two pipes with a gap between them. Each set of two horizontal support steel pipes 3 is equipped with a tie bolt assembly 1, which extends downward into the casting space 5. The pre-embedded component 6 is installed between the lower ends of the two sets of tie bolt assemblies.

[0019] The main support steel pipe 2 is a seamless steel pipe with an outer diameter of 60mm and a wall thickness of 5mm. It is cut into sections of different lengths according to the actual layout and stress requirements of the construction site. The horizontal connecting steel pipe is a steel pipe with an outer diameter of 42mm and a wall thickness of 4mm. It is vertically fixed to the main support steel pipe 2 to form a stable grid structure. Each section of steel pipe is fixed by welding or fastener connection.

[0020] Furthermore, the tie bolt assembly 1 includes a bolt body 101, which is made of 42CrMo steel, with a nominal diameter of M16-M24 and a length of 800mm. Nuts and washers 103 are provided at both ends of the bolt body 101; angle steel 4 is loosely connected to the bolt body 101 via nuts, and embedded parts 6 are fixedly installed between the angle steel 4 of the two sets of tie bolt assemblies.

[0021] Furthermore, the bolt body 101 is inserted into the gap between each group of two horizontal support steel pipes 3. The upper end of the bolt body 101 is fixed above the two horizontal support steel pipes 3 by adjusting the nut. The angle steel 4 is fixed to the lower end of the bolt body 101 by tightening and loosening the nut. For embedded parts 6 of different shapes, a variety of special fixing angle steels 4 are designed. The angle steel 4 is model L75×8, and its length is adapted to the size of the embedded part 6. One end of the angle steel 4 is welded to the embedded part 6 using a full welding process to ensure connection strength; the other end is drilled with a hole diameter adapted to the diameter of the tie bolt, and is fixed to the tie bolt by a nut.

[0022] Furthermore, the nut is a wing nut 102. With this configuration, the operator can rotate it by hand to quickly and finely adjust the tightness of the tie bolt, thereby adjusting the positional accuracy of the embedded part 6. The adjustment range can reach ±5mm.

[0023] The implementation steps during construction are as follows:

[0024] S1: Based on the position of the embedded part 6, first build a steel pipe support structure; fix the main support steel pipe 2 to each other by welding or pipe clamps, and then fix the horizontal connecting steel pipe to the main support steel pipe 2 by welding or fasteners to form a stable frame, ensuring that each connection point is firm and reliable, and the verticality error of the frame is controlled within ±5mm.

[0025] S2: Based on the shape of the embedded part 6, select a suitable angle steel 4 for fixing. Ensure that the embedded part 6 is installed in an accurate position and that there are no defects such as incomplete welding or loosening at the welding or connection points of the angle steel 4.

[0026] S3: Pass the tie bolt body 101 through the horizontal connecting steel pipe and angle steel 4 in sequence, put the washers 103 on both ends, tighten the nuts (wing nuts 102) for initial tightening. At this time, the tension of the tie bolt should be moderate to avoid over-tightening, which may cause deformation of the embedded parts 6 or uneven stress on the steel pipe structure.

[0027] S4: Adjusting nut (wing nut 102). Based on the data fed back by the laser displacement sensor or the measurement results of on-site measuring tools (such as total station, level), the construction personnel make fine adjustments to the planar position of the embedded part 6. By rotating the nut (wing nut 102), the embedded part 6 can be moved in the horizontal direction with an adjustment accuracy of ±1mm until the design plane coordinates and flatness requirements are met.

[0028] S5: Check the verticality of the embedded part 6. If there is a deviation, it can be corrected by adding or removing shims 103 between the steel pipe support structure and the template or by finely adjusting the tightness of the fasteners to ensure that the verticality error of the embedded part 6 is controlled within ±2°.

[0029] S6: Conduct a comprehensive inspection of the installed reinforcement system and embedded parts 6, focusing on the tightness of the tie bolts, the stability of the steel pipe structure, and the positional accuracy of the embedded parts 6. If any abnormalities are found, rectify them immediately, and then proceed with the pouring.

[0030] Choose a suitable concrete pouring method. If pumped concrete is used, the pumping pressure should be reasonably controlled to avoid excessive impact force on the embedded part 6 and the reinforcement system. During vibration, the vibrator should avoid direct impact on the embedded part 6, tie bolt assembly 1, and steel pipe. The vibration distance should be maintained between 20-30cm to prevent displacement of the embedded part 6 caused by vibration. During the pouring process, the construction personnel should regularly check the position of the embedded part 6. If any displacement is found, pouring should be stopped immediately, and corresponding corrective measures should be taken, such as quickly adjusting the tie bolts and reinforcing the steel pipe structure.

[0031] S7: Removal of structural components; When the concrete reaches more than 70% of its design strength, begin removing some components of the reinforcement system;

[0032] First, loosen the nuts (wing nuts 102) at both ends of the tie bolt, remove the tie bolt body 101 and washer 103, and collect and preserve them to avoid loss; then cut off the welded part between the fixing angle steel 4 and the embedded part 6 (when using gas cutting, be careful to protect the surface of the embedded part 6), and finally dismantle the steel pipe support structure, sort and transport the steel pipes to the designated site for storage so that they can be reused later.

[0033] S8: Clean the surface of the embedded part 6 of any residual concrete slurry, debris, etc., and use tools such as wire brushes and sandpaper to polish the surface of the embedded part 6 until it is smooth. Check the final installation quality, such as positional deviation and verticality. If there are any non-compliance with the standards, record them in time and report them for subsequent rectification.
