Description
Technical Field
[0001] The utility model relates to the technical field of building engineering, and in particular to a UHPC modular exterior wall corner connection box. Background Art
[0002] UHPC stands for ultra-high performance concrete, also known as reactive powder concrete. Its constituent materials consist of particles of different sizes that are packed most densely in the best proportion, that is, the gaps between millimeter-level particles are filled with micron-level particles, and the gaps between micron-level particles are filled with submicron-level particles. UHPC dry-hanging curtain wall is a curtain wall made of ultra-high performance concrete.
[0003] At present, the connection nodes between UHPC exterior wall panels and composite beams and prefabricated floor slabs in prefabricated buildings usually adopt wet hanging connection, that is, the connecting steel bars are embedded in the exterior wall panels so that the upper part of the connecting steel bars extends into the cast-in-place layer of the composite floor slabs and the upper part of the prefabricated composite beams, and the cast-in-place concrete is fixed to the connection. This wet hanging connection must be constructed simultaneously with the main body of the building, and the construction period is relatively long. Errors and offsets occur during the pouring of concrete, and they cannot be adjusted after curing, resulting in poor installation accuracy. Utility Model Content

[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.
[0019] Embodiment 1, as Figure 1-3 As shown, a UHPC modular exterior wall corner connection box comprises a first box body 1 and a second box body 2, the front sides of the first box body 1 and the second box body 2 are both open surfaces, the left side and the lower side of the first box body 1 are both provided with first pre-embedded anchor nails 3, the right side and the lower side of the second box body 2 are both provided with second pre-embedded anchor nails 4, the first box body 1 is pre-embedded and fixed at two corner positions of the right side of the UHPC exterior wall 10 by the first pre-embedded anchor nails 3, and the second box body 2 is pre-embedded and fixed at the corner position of the left side of the UHPC exterior wall 10 by the second pre-embedded anchor nails 4; the corner positions of the two UHPC exterior walls 10 are connected to each other through the first box body 1 and the second box body 2;
[0020] A left-right adjustment long slot hole 5 is provided on the upper surface of the first box body 1, a first inside-outside adjustment slot hole 6 is provided on the right side surface of the first box body 1, a second inside-outside adjustment slot hole 7 is provided on the upper surface of the second box body 2, and an up-down adjustment long slot hole 8 is provided on the left side surface of the second box body 2; the up-down adjustment long slot hole 8 is directly opposite to the first inside-outside adjustment slot hole 6, and the up-down adjustment long slot hole 8 is connected to the first inside-outside adjustment slot hole 6 by a connecting bolt 9.
[0021] Working principle:
[0022] When in use, when the UHPC outer wall 10 is produced and cast, the first box body 1 and the second box body 2 are respectively arranged at the corner positions of the left and right sides of the UHPC outer wall 10, and the first pre-embedded anchor nails 3 and the second pre-embedded anchor nails 4 are respectively corresponding to the four sides of the UHPC outer wall 10, so that the first pre-embedded anchor nails 3 and the second pre-embedded anchor nails 4 are buried in the UHPC outer wall 10; thereby achieving a stable fixing effect on the first box body 1 and the second box body 2.
[0023] When connecting and fixing two UHPC outer walls 10, one of the sides of the two UHPC outer walls 10 can be made to correspond to each other, as shown in the figure, first make the first box body 1 and the second box body 2 correspond to each other, so that the up and down adjustment long slot hole 8 and the first inside and outside adjustment slot hole 6 correspond to each other; then pass the connecting bolts 9 through the up and down adjustment long slot holes 8 and the first inside and outside adjustment slot holes 6 of the first box body 1 and the second box body 2 in sequence and tighten them through nuts to achieve reliable connection and fixation. In this embodiment, when connecting the two UHPC outer walls 10, the relative height of the two UHPC outer walls 10 can be adjusted up and down according to different positions and installation adjustment requirements by adjusting the long slot holes 8 up and down; the depth of the two UHPC outer walls 10 in the relative inside and outside directions can be adjusted by the first inside and outside adjustment slot holes 6.
[0024] In addition, when the UHPC outer wall 10 needs to be connected to the composite beam, the left and right adjustment slots 5 and the second inner and outer adjustment slots 7 can be respectively matched with the installation holes of the composite beam, and connected and fixed by connecting bolts 9, so as to achieve the connection and fixation between the UHPC outer wall 10 and the composite beam. In this embodiment, the left and right adjustment slots 5 can also be used to adjust the left and right position of the UHPC outer wall 10 in the horizontal direction. The second inner and outer adjustment slots 7 are used to adapt to the connection and fixation in different depth directions. Thereby, the reliable connection and three-dimensional adjustment effect between the UHPC outer walls 10 and between the UHPC outer wall 10 and the composite beam are effectively achieved. It also makes on-site construction simpler and more convenient, thereby effectively improving efficiency and saving costs.
[0025] Embodiment 2, as a further preferred embodiment of embodiment 1, a galvanized steel gasket 11 is provided between the first box body 1 and the second box body 2, and the galvanized steel gasket 11 is fixed between the up-and-down adjustment slot hole 8 and the first inner-and-outer adjustment slot hole 6 by connecting bolts 9. The galvanized steel gasket 11 can ensure the stability of the first box body 1 and the second box body 2 when they are connected to each other by the connecting bolts 9, and can also effectively optimize the space and size of the connection.
[0026] Embodiment 3, as a further preferred embodiment of embodiment 1, the outer sides of the joints of two adjacent UHPC outer walls 10 are respectively filled with PU foam boards and sealants 12. By filling the outer sides of the joints of the two UHPC outer walls 10 with PU foam boards and sealants 12, the sealing of the joints where the two UHPC outer walls 10 are connected is effectively ensured, so as to avoid the problem of corrosion at the joints between the first box body 1 and the second box body 2, thereby effectively improving the service life.
[0027] Embodiment 4, as a further preferred solution of embodiment 1, two first inner and outer adjustment slots 6 and two second inner and outer adjustment slots 7 are respectively provided in parallel with each other. Thus, two-point connection and fixation can be performed at the connection points between the UHPC outer walls 10 and between the UHPC outer walls 10 and the composite beams, thereby further ensuring reliable connection between the UHPC outer walls 10 and between the UHPC outer walls 10 and the composite beams.
