Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to an assembled connector for civil engineering. Background Art

[0002] Prefabricated buildings are concrete structures assembled from prefabricated concrete components through reliable connection methods. The installation process generally includes the following steps:

[0003] Measurement and layout: determine the location and size of the wall panels;

[0004] Leveling with gaskets: Install gaskets at the four corners of the lower part of the wall panel to ensure that the upper and lower edges of the wall panel are flush and prevent the gaskets from shifting.

[0005] Prefabricated wall panels in place: transport the prefabricated wall panels to the construction floor, and the installers hold the wall panels steady according to the positioning lines of the prefabricated wall panels marked on the floor. They also use a small mirror to check whether the lower sleeve of the wall panel is aligned with the position of the connecting steel bar. After the inspection is qualified, the hook is slowly lowered to make the wall panel fall onto the leveling pad and be placed firmly in place;

[0006] Install diagonal braces: Install diagonal braces to ensure the stability and verticality of the wall panels.

[0007] Grouting: Pour grouting material into the sleeve, and when the grouting beam is completely solidified, the prefabricated wall panel is fixed and installed;

[0008] When traditional prefabricated wall panels are installed, there is a small gap between the bottom of the wall panels and the bottom of the floor slab. Although this gap can be filled with grouting material during the grouting process, due to the small amount of filling in this part, this part is prone to produce small cracks due to material deformation during the later use of the building, especially when used as an exterior wall. These cracks will cause water seepage. In order to avoid this situation, a civil engineering assembled connector is provided. Utility Model Content

A docking groove 102 is formed at the bottom of the wall body 101, and the bottom of the sleeve 103 communicates with the docking groove 102;

[0029] The wall body 101 is connected to the floor through the embedded docking member 2, and the embedded docking member 2 is embedded inside the floor;

[0030] The embedded docking member 2 includes an I-shaped seat 201, a through hole 202, a transverse bar 203, and a longitudinal bar 204;

[0031] The through holes 202 are symmetrically opened on both sides of the top of the I-shaped seat 201 and penetrate to the bottom of the I-shaped seat 201. The I-shaped seat 201 is sleeved on the outer side of the embedded steel bar 3 through the through holes 202. During the floor pouring, the bottom "convex" part of the I-shaped seat 201 and the embedded steel bar 3 are fixed. The horizontal part of the top of the I-shaped seat 201 is located above the floor surface;

[0032] A plurality of transverse bars 203 are provided, and the plurality of transverse bars 203 are uniformly distributed and fixed along the horizontal longitudinal direction on the top of the I-shaped seat 201. A plurality of longitudinal bars 204 are provided, and the plurality of longitudinal bars 204 are uniformly distributed along the horizontal transverse direction and fixed on the tops of the plurality of transverse bars 203;

[0033] The wall body main body 101 is inserted into the outer side of the horizontal part at the top of the I-shaped seat 201 through the docking groove 102. The upper surface of the longitudinal bar 204 is attached to the top of the inner wall of the docking groove 102. Through the cooperation of the docking groove 102, the transverse bar 203, and the longitudinal bar 204, a grouting chamber is formed between the wall body main body 101 and the I-shaped seat 201, thereby increasing the connection force between the wall body main body 101 and the I-shaped seat 201 and the anti-deformation force of the grouting solidification area.

[0034] In this embodiment: When installing the precast wall 1, the operation steps are as follows:

[0035] Before the floor pouring, first sleeve the I-shaped seat 201 on the outer side of the embedded steel bar 3 at the set position through the through hole 202. Finally, the I-shaped seat 201 is placed horizontally as a whole, and the lower surface of the horizontal part at the top of the I-shaped seat 201 is flush with the upper surface after the floor pouring is formed. The upper end of the embedded steel bar 3 protrudes above the I-shaped seat 201;

[0036] After the floor pouring is completed and solidified, the installation of the precast wall 1 can be carried out. At this time, the precast wall 1 is hoisted above the I-shaped seat 201 by a hoisting device, and then the precast wall 1 is slowly lowered so that the wall body main body 101 is inserted into the outer side of the horizontal part at the top of the I-shaped seat 201 through the docking groove 102, and the embedded steel bar 3 is inserted into the inside of the sleeve 103.

Then, the grouting operation can be carried out through the grouting hole 104. The grouting material can enter the inside of the sleeve 103 and the docking groove 102 area. Finally, the entire area of the docking groove 102 and the inside of the sleeve 103 is filled. After the grouting material solidifies, the fixation of the precast wall 1 is completed;

[0037] Through the structural settings of multiple longitudinal bars 204, transverse bars 203, and docking grooves 102, not only does the grouting layer between the I-shaped seat 201 and the wall body 101 become thicker, so that after the grouting material solidifies, it can better overcome material deformation and avoid cracks, keeping the splicing part of the precast wall 1 with good water-proofing performance. At the same time, through the grid space formed by the longitudinal bars 204 and the transverse bars 203, the grouting material filling layer is also formed into a grid shape accordingly. Compared with the traditional horizontal plane structure, its connection force is stronger.

[0041] In this embodiment: Through the structural facilities of the communication groove 205 and the slurry flow groove 206, the grouting material can better fill the gap between the transverse bar 203 and the longitudinal bar 204, ensuring the integrity of the grouting material filling.

[0042] Please refer specifically to Figures 1 to 3 , the inner wall size of the docking groove 102 is larger than the outer wall size of the horizontal part at the top of the I-shaped seat 201.
