Description

Technical Field

[0001] The invention relates to a crown beam manufacturing device, in particular to an adjustable mold for crown beam manufacturing and a use method thereof. Background Art

[0002] In the construction industry, foundation pit refers to the space below the ground excavated for the construction of building foundations and basements. The foundation pit is a temporary pit excavated for the building foundation. It is a temporary project. Its function is to provide a space so that the foundation masonry work can be carried out according to the position specified by the design. In general, a foundation pit with an excavation depth greater than or equal to 5M is called a deep foundation pit. Deep foundation pit support refers to the support, reinforcement and protection measures for the side walls and surrounding environment of the deep foundation pit to ensure the safety of underground structure construction and the surrounding environment of the foundation pit. When constructing a deep foundation pit, it is generally necessary to set up a support structure before excavating the earth.

[0003] At present, most deep foundation pit construction in my country adopts anchor column concrete support as the support system, that is, a circle of cast-in-place piles with anchor column concrete structure is set around the foundation pit to form a row of piles, and then a circle of crown beams is set above the cast-in-place piles, and horizontal supports are set in the middle of the crown beams to form an internal support structure system. In the process of manufacturing the crown beam, it is necessary to set a mold on the top of the cast-in-place pile, and then pour concrete in the mold. After the concrete is completely solidified, the mold is removed to complete the production of the crown beam.

[0004] However, in the process of making the crown beam, the traditional mold is specially designed according to the specifications of the crown beam to be manufactured (such as length, width, height and angle, etc.), especially the crown beam needs to be connected with the anchor rod, and the anchor rod needs to extend vertically from the riveted surface of the crown beam. Since the angles of the anchor rods in different crown beams are different, the height position and inclination angle of the riveted surfaces of different crown beams are different. Therefore, in the prior art, when it is necessary to make crown beams of different specifications, it is necessary to redesign the mold, which is not only time-consuming and labor-intensive, but also reduces the construction progress and increases the construction cost. Summary of the invention

When the angle of the movable plate is fixed, the locking nut is loosened to drive the sliding seat to move vertically, thereby adjusting the height of the sliding seat and the movable plate rotatably connected to the sliding seat. When the sliding seat reaches a predetermined height, the locking nut is locked to fix the sliding seat and the movable plate to a specified height, thereby completing the installation of the adjustable mold of the present invention. In addition to the above adjustment method, the height of the movable plate can also be adjusted first, and then the angle of the movable plate can be adjusted to adapt to the manufacture of crown beams of different specifications. Finally, concrete is poured into the adjustable mold of the present invention to form a crown beam. After the concrete solidifies, the first fixed plate, the second fixed plate, the movable plate, the height adjustment mechanism and the angle adjustment mechanism are removed, thereby completing the entire process of crown beam production.

Through the above structure, not only can the sliding seat 8 realize vertical sliding on the second fixed plate 3, but also the sliding seat 8 can be locked at a determined position on the second fixed plate 3 by the cooperation between the locking nut 10 and the locking screw. The advantage of setting the above structure is that the sliding seat 8 is fixed at a determined position on the second fixed plate 3 by the cooperation between the locking nut 10 and the locking screw. Through the above structure, the sliding seat 8 can be locked in a specific position in advance before the movable plate 5 is installed on the sliding seat 8, so as to facilitate the installation between the sliding seat 8 and the movable plate 5.

[0038] See also Figure 1-Figure 5 The angle adjustment mechanism includes a screw rod 7 and a screw nut 9, wherein one end of the screw rod 7 is provided with a connection portion 7-1, and the connection portion 7-1 is rotatably connected to the movable plate 5, and the other end is connected to the screw nut 9 after passing through the sliding groove 3-1. By rotating the screw nut 9, the screw rod 7 can be driven to move horizontally, so as to adjust the rotation angle of the movable plate 5. In combination with the height adjustment mechanism, before installing the adjustable mold of the present invention, the movable plate 5 can be installed on the second fixed plate 3, and the angle and height of the movable plate 5 can be adjusted. Then, the movable plate 5 on the second fixed plate 3 can be directly sleeved on the anchor column 6 of the pile row 11, thereby completing the installation of the adjustable mold of the present invention.
