Description

Technical Field

[0001] The utility model belongs to the technical field of wall connecting parts, and specifically relates to an assembled wall connecting part. Background Art

[0002] The cast-in-place beam using the bracket method is a commonly used beam construction method. Compared with other beam construction methods, the construction period of the cast-in-place beam using the bracket method is shorter. The erection and dismantling of the bracket is relatively simple, and the pouring of concrete is also relatively rapid, so the construction period can be greatly shortened. It has the advantages of short construction period, stable structure, wide adaptability and material saving. Among them, the wall connection of the cast-in-place beam using the bracket is the key to ensure the stability of the bracket.

[0003] When installing traditional cast-in-place beam brackets, it is necessary to embed steel plates in the pier body in advance, and then weld them together through steel sections. One end of the steel section is welded to the steel plate, and the other end is welded to the bracket. Disadvantages of this method: The use of embedded steel plates for wall connection not only has the disadvantage of large steel loss, but also requires the position of the embedded steel plates to be repaired during the later pier body appearance repair process. Not only is the construction complex and difficult to operate, the maintenance cost is high, and there are a lot of welding risks, and it is also prone to rust and safety hazards. Both ends of the wall connection are welded, the connection speed is slow, the welding volume is large, and workers need to work at high altitude for a long time, which poses a great safety hazard; and the harmful gases generated by welding cannot be effectively treated, the air pollution is large, and it is not conducive to environmental protection.

[0004] The utility model patent with announcement number CN212562435U was disclosed on February 19, 2021. The name is a wall connection structure, which includes a wall body, a short steel pipe is embedded on the right side of the top of the wall body, a double buckle connector is clamped on the top of the surface of the short steel pipe, and the inner cavity of the double buckle connector is clamped with the wall connection body, and both sides of the surface of the wall connection body are fixedly connected with an external dense mesh safety net, and the top and bottom of the inner side of the external dense mesh safety net are fixedly connected with bamboo scaffolding boards, and both sides of the top and bottom of the inner side of the external dense mesh safety net are welded with connection blocks. The wall connection structure is not convenient to operate, and some components are connected by welding, which poses safety risks in the construction process. Utility Model Content

[0020] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of embodiments, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0021] like Figures 1 to 3 As shown, the assembled wall connecting member includes a pier body 1 and a steel pipe column 2. A steel plate 3 is provided on the side of the pier body 1. The pier body 1 and the steel plate 3 are connected by embedded bolts 4. A wall connecting steel 5 is connected between the steel plate 3 and the steel pipe column 2.

[0022] The steel plate 3 is a connecting plate connecting the embedded bolts 4 and the wall connecting steel 5. After the formwork of the pier body 1 is removed, the bolt connection holes 8 on the steel plate 3 are aligned with the threaded positions of the cone 10, and the force-bearing bolts 9 are firmly connected with the cone 10 bolts to fix the steel plate 3. The steel plate 3 is connected to the outside of the pier body 1 and installed after the pouring of the pier body 1 is completed. This avoids the situation where the steel plate 3 embedded in the pier body 1 cannot be removed, which can save the use of steel and reduce costs. The embedded bolts 4 are embedded in the pier body 1 during the construction of the pier body 1 to play an anchoring role. The embedded bolts 4 are the main force-bearing components of the wall connecting parts. Their length is calculated, and their embedded length can be flexibly adjusted according to different working conditions. The wall connecting steel 5 is used to support the tensile pressure between the pier body 1 and the steel pipe column 2.

[0023] like Figure 1 and Figure 3 As shown, the steel plate 3 and the steel pipe column 2 are both fixedly connected with ear plates 6, the end of the wall-connecting steel 5 is located between the ear plates 6, and the middle of the ear plates 6 and the two ends of the wall-connecting steel 5 are penetrated by connecting pins 7. The two ear plates 6 on the steel plate 3 are welded in the processing plant and fixed in place together with the steel plate 3. The ear plates 6 are also welded on the steel pipe column 2 to provide an installation position for the wall-connecting steel 5. The connecting pins 7 are used to connect the wall-connecting steel 5 and the ear plates 6. The wall-connecting steel 5 is installed by the constraint of the connecting pins 7. The connection efficiency is high and the speed is fast, which reduces the time of high-altitude operations and greatly reduces safety risks.

[0024] like Figure 2As shown, the embedded bolt 4 includes a stress bolt 9, which extends from the pier body 1 and presses the steel plate 3; the embedded bolt 4 also includes a cone 10, which is threadedly connected to the stress bolt 9, and an embedded plate 11 is provided at the end of the embedded bolt 4. One end of the cone 10 is in the same plane as the side of the pier body 1, and the cone 10 and the embedded plate 11 are both located inside the pier body 1. The embedded bolt 4 consists of a stress bolt 9, a cone 10, and an embedded plate 11. The embedded bolt 4 is arranged horizontally, and the bottom surface of the cone 10 is completely fitted with the pier body 1 to ensure the verticality of the embedded part and the surface of the pier body 1. The thread in the cone 10 is used to connect with the stress bolt 9 after the template is removed, and the steel plate 3 is pressed and fixed by the threaded connection between the stress bolt 9 and the cone 10. The steel plate 3 is easy to install and disassemble, can be recycled, and there is no outdoor welding operation, no harmful gas from welding will be generated, and the operation process is green and environmentally friendly. The embedded plate 11 is a component connected to the internal steel bars of the pier body 1. After the embedded bolts 4 are positioned, the steel bars of the pier body 1 are welded and fixed to it to ensure that the position will not move during the concrete pouring process, and the anchoring effect of the embedded bolts 4 is more reliable.

[0025] like Figure 3 As shown, a limiting portion 12 and a guiding portion 13 are respectively provided at both ends of the connecting pin 7. The diameter of the limiting portion 12 is larger than that of the connecting pin 7, and the guiding portion 13 is a tapered structure. The limiting portion 12 can prevent the connecting pin 7 from falling out after installation, and a split pin can be installed on the guiding portion 13 to constrain the wall-connecting steel 5 on the ear plate 6 to ensure that the connection will not fail. The tapered guiding portion 13 can be smoothly inserted into the ear plate 6 and the wall-connecting steel 5, thereby improving the convenience of operation.

[0026] like Figure 3 As shown, the wall connecting steel 5 is a pair of channel steels. The structural strength of the channel steel is reliable, and it can completely resist the tensile pressure transmitted by the pier body 1 and the steel pipe column 2, ensuring the overall wall connection. The channel steels are relatively arranged to reduce space occupation and meet the space requirements for installation between the ear plates 6.

[0027] like Figure 1 As shown, the wall connecting steel 5 is arranged horizontally. The height of the two ear plates 6 on the steel plate 3 and the steel pipe support is consistent, thereby ensuring that the wall connecting steel 5 is horizontal, that is, ensuring that the direction of the tension and pressure transmitted between the pier body 1 and the steel pipe column 2 is horizontal.

[0028] like Figure 1 and Figure 2 As shown, the embedded bolts 4 are arranged in pairs. A plurality of evenly distributed embedded bolts 4 can improve the stability of the fixing of the steel plate 3.

[0029] The assembled wall connection part replaces the traditional method of pre-embedded steel plate 3 in the pier body 1, and provides a new idea for the cast-in-place beam bracket wall connection. Compared with the traditional method of pre-embedded steel plate 3, which requires multiple people or machinery to complete the installation process, the assembled wall connection part has light embedded bolts 4, and only one person is required to complete the installation and reinforcement of embedded bolts 4. The appearance of the pier body 1 using the assembled wall connection part only needs to be simply processed at the bolt hole, while the traditional solution requires processing the entire range of the embedded steel plate 3, which is difficult to process and costly.

[0030] The installation process of the assembled wall connection is as follows:

[0031] 1. During the construction of the pier body 1, the operator embeds and fixes the embedded bolts 4, the cone 10, and the embedded plate 11 to the designated position of the pier body 1;

[0032] 2. After the pier body 1 is poured, the formwork is removed and the foam glue in the cone 10 is cleaned;

[0033] 3. The steel plate 3 and the ear plate 6 are welded in the back field;

[0034] 4. The force-bearing bolt 9 is connected to the inner thread of the cone 10 to securely install the steel plate 3 and the ear plate 6.

[0035] 5. The wall-connecting steel 5 and the ear plate 6 are connected by a connecting pin 7. After the connecting pin 7 passes through, a cotter pin is arranged to prevent the pin from falling off.

[0036] 6. Then fix the other end of the wall steel 5 to the ear plate 6 on the bracket steel pipe column 2 with the connecting pin 7, so that the bracket and the pier body 1 structure are effectively connected.

[0037] The assembled wall connection part replaces the traditional construction method of pre-embedded steel plate 3 and welded steel in the pier body 1. The steel plate 3 is fixed with pre-embedded bolts 4 and the steel is fixed with connecting pins 7, which avoids the harmful gas generated by welding, simplifies the construction steps, is simple and convenient to operate, improves the construction efficiency, and eliminates the safety hazard of workers working at height for a long time. The steel plate 3 is fixed with bolts, which is easy to handle. The installation and reinforcement of the pre-embedded bolts 4 can be completed by a single person. At the same time, the structure of the pre-embedded bolts 4 is reasonably designed to ensure a reliable anchoring effect, which can improve the stability of the support construction process. There is no need to repair the position of the embedded steel plate 3 during the later repair of the appearance of the pier body 1. The subsequent steel plate 3 can also be smoothly removed, which reduces the loss of steel and reduces costs. The assembled wall connection part also has the advantages of simple assembly, convenient transportation, and convenient operation, which can meet the requirements of support wall connection under most working conditions.

[0038] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
