Description

Technical Field

[0001] This utility model relates to the field of prefabricated wall installation technology, specifically to the connection structure between prefabricated walls and floors. Background Technology

[0002] In the field of prefabricated buildings, the efficient and precise connection between prefabricated walls and floors has always been a technical challenge in construction. Traditional installation methods usually rely on on-site measurement and manual alignment. During manual alignment, a person needs to hold a small mirror and shine it back onto the bottom of the prefabricated wall to confirm whether the reserved steel bars inside the floor are aligned with the reserved holes at the bottom of the prefabricated wall. This process is not only cumbersome and inefficient, but also prone to installation errors due to inaccurate alignment, which can affect the overall structural quality.

[0003] In addition, existing technology directly inserts the pre-reserved holes at the bottom of the precast wall panel into the pre-reserved steel bars inside the floor and then performs grouting. In the critical grouting process, problems such as leakage and overflow often occur. Furthermore, the grout is only connected to the floor and the precast wall in a planar manner, resulting in poor mechanical interlocking ability and affecting the connection strength of the precast wall panel after it is installed on the floor.

[0004] Therefore, there is an urgent need for a prefabricated wall and floor connection structure that can achieve rapid and accurate positioning, stable connection, and easy construction. Utility Model Content

[0005] The purpose of this utility model is to provide a connection structure for prefabricated walls and floors to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated wall and floor connection structure, including a prefabricated base, on which a prefabricated wall is installed, and the prefabricated wall is installed on the floor via the prefabricated base. The prefabricated base has a positioning groove, and the bottom end of the positioning groove has a positioning hole. A guide ramp is provided at the top of the side wall of the positioning groove. A flange connector is provided at the bottom end of the prefabricated wall in conjunction with the guide ramp, and an insertion groove is provided at the bottom end of the prefabricated wall. An inlet groove is provided on the guide ramp, and an inlet slide is provided on the flange connector. The inlet slide slides into and engages with the inlet groove. At least one grouting port is provided on the prefabricated base. A grouting channel is formed between the flange connector and the prefabricated base, and the grouting port communicates with the grouting channel.

[0007] The present invention is further configured such that a bottom bearing plate is formed at the bottom end of the precast base, and side bearing plates are formed on both sides of the bottom bearing plate. The cooperation between the bottom bearing plate and the side bearing plates realizes the initial bearing load of the precast wall during installation, ensuring the uniformity of the force on the precast base.

[0008] The present invention is further configured such that a shock-absorbing rubber pad is provided in the positioning groove, the shock-absorbing rubber pad is located between the bottom bearing plate and the flange connector, the shock-absorbing rubber pad absorbs seismic energy, and cooperates with the bottom bearing plate to form a composite shock-absorbing structure of "rigid foundation + flexible buffer", thereby improving the shock absorption effect.

[0009] The present invention is further configured such that an adjustment plate is provided at the bottom end of the precast wall, a first biting tooth is provided at the bottom end of the adjustment plate, and a second biting tooth is provided at the top end of the bottom bearing plate. The first biting tooth and the second biting tooth bite each other. The adjustment plate is welded to the bottom of the precast wall. The first biting tooth can bite the bottom bearing plate through the second biting tooth to prevent the precast wall from slipping during the installation process, thereby further improving the stability of the precast wall when it is installed on the floor.

[0010] The present invention is further provided that the side of the precast base is provided with an adjusting bolt, preferably with a scale mark, for fine adjustment of verticality during the installation of the precast wall, and the adjustment error can be controlled within ±1mm.

[0011] The present invention is further provided that the side of the precast wall is equipped with a diagonal support. The diagonal support is mainly used for temporary fixing and correction of the precast wall when it is installed on the floor, to ensure the verticality and stability of the wall, prevent overturning, and ensure construction safety.

[0012] The present invention is further configured such that the inclined support includes a support rod, both ends of which are hinged with connecting parts. The length of the support rod is adjustable, and the connecting parts are fixed to the floor and the precast wall respectively by bolts, fixing nails and other fixing parts, so as to achieve stable support for the precast wall when it is installed on the floor.

[0013] The present invention is further configured such that the support rod includes an adjusting section, and connecting sections are threaded on both sides of the adjusting section. The connecting sections are hinged to the connecting parts. The overall support length of the support rod can be adjusted by the threaded engagement structure of the adjusting section and the connecting sections. By rotating the adjusting section, the connecting sections can be adjusted in and out at both ends of the adjusting section, thereby adjusting the overall length of the support rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1.

[0027] In summary, the working principle and specific workflow of this utility model are as follows: During installation, the pre-reserved steel bars built into the floor are passed through the positioning holes 4 on the prefabricated base 1, and the prefabricated base 1 can be installed and fixed on the floor through the built-in pre-reserved expansion bolts and other structures. Then, using existing hoisting equipment, the precast wall 2 is moved above the precast base 1, and the precast wall 2 is slowly lowered. At the same time, the guide groove 8 and the guide strip 9 are aligned, and under the guidance of the guide ramp 5, the flange connector 6 can be accurately and quickly inserted into the positioning groove 3, and the steel bars built into the floor are inserted into the corresponding insertion groove 7, so as to realize the rapid and accurate installation of the precast wall 2 during installation. In the above process, the guide ramp 5 and the flange connector 6 cooperate to provide initial guidance in the docking direction, and the guide groove 8 and the guide strip 9 cooperate to provide precise guidance in the installation position, so that the precast wall 2 can be accurately and quickly installed on the precast base 1, realizing the convenient installation of the precast wall 2 on the floor. This eliminates the step in the existing technology that requires a person to hold a small mirror and repeatedly observe whether the alignment between the steel bar and the insertion groove 7 is accurate, thus improving the convenience and efficiency of the installation of the precast wall 2. After the precast wall 2 is installed on the precast base 1, the first biting tooth 16 and the second biting tooth 17 are in a mutually biting position. Meanwhile, the shock-absorbing rubber pad 14 is located between the adjustment plate 15 and the bottom bearing plate 12 to achieve shock absorption and protection at the connection surface between the precast wall 2 and the precast base 1; Afterwards, the prefabricated wall 2 can be finely adjusted during installation in the positioning groove 3 by turning the adjusting bolt 18, thereby improving the installation accuracy of the prefabricated wall 2; Afterwards, diagonal supports 19 are installed for temporary fixing and correction of the precast wall 2 when it is installed on the floor, to ensure the verticality and stability of the wall, prevent overturning, and ensure construction safety. Then, high-strength non-shrink grout is injected into the grouting channel 11 through the grouting port 10, so that a composite connection of "mechanical interlocking + material bonding" is formed between the precast base 1, the grout and the precast wall 2. In the above structure, the precast base 1 and precast wall 2 can be precast in the factory to ensure the accuracy of the node dimensions, shorten the on-site installation time, and avoid the problems of grouting leakage and over-grouting. In this utility model, the precast base 1 can be a concrete base or a steel base.

[0028] This utility model provides an air vent (such as a φ5mm small hole reserved at the top or side) in the grouting channel 11 to avoid air bubbles remaining and affecting the bonding strength.
