Description

Technical Field

[0001] The utility model relates to the technical field of concrete surface layer elevation control devices, and specifically discloses a concrete surface layer elevation control bracket. Background Art

[0002] During the construction of the concrete surface layer, the channel steel used as the formwork has problems such as weak support, large errors in adjusting the elevation and flatness, and loose joints in the steel formwork, which can easily lead to problems in the elevation and flatness control of the concrete construction.

[0003] To solve the above problems, the patent with announcement number CN213867245U discloses a road surface concrete construction mold, in which the assembled channel steel is formed by the left and right butt joint of the channel steel through a socket-type component, and the inner and outer sides of the channel steel are respectively evenly distributed with reserved plug holes for the separation seam template and longitudinal locking parts, and the assembled channel steel is fixed to the vertical positioning rod with adjustable height through the longitudinal locking part, and the vertical positioning rod is vertically fixed to the road base. By using a socket-type component to horizontally butt the two channel steels together, the left and right channel steels slide up and down along the vertical positioning rod through the U-shaped steel plate and are fixed to the vertical positioning rod with adjustable height through the wedge-shaped fixing pin that passes through the U-shaped steel plate to limit the position, thereby realizing the vertical fixation and elevation of the left and right channel steels.

[0004] In the above scheme, the positioning rods set on the cylindrical steel columns and the friction fixation between the positioning rods and the longitudinal locking parts will inevitably sink during the machine vibration during the construction process, affecting the elevation of the channel steel, which requires timely adjustment and verification. However, due to the lack of height adjustment components, it is difficult to adjust and verify the height of the channel steel during construction, and the wedge-shaped fixing pins need to be knocked out, which is easy to affect the height of the adjacent channel steels and affect the construction quality. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a concrete surface elevation control bracket to solve the problem of lack of height adjustment components, difficulty in adjusting and verifying the height of channel steels during construction, and the need to knock out the wedge-shaped fixing pins, which easily affects the height of adjacent channel steels and affects the construction quality.

[0006] To achieve the above purpose, the technical solution of the utility model is:

[0007] A concrete surface layer elevation control bracket includes a positioning rod and a channel steel, wherein at least one mounting seat is arranged on the channel steel; after the positioning rod passes through the mounting seat, it is vertically fixed on the base of the site; connecting components are arranged on the wing plates at both ends of the channel steel; the connecting components are used to connect the channel steels of two adjacent concrete surface layer elevation control brackets; at least one height adjustment component is also arranged on the bottom wing plates of the channel steel. By arranging the height adjustment component, the height of the channel steel can be adjusted and checked in time during the construction process, avoiding knocking out the wedge-shaped fixing pin to affect the height of the adjacent channel steel, and ensuring high quality of construction.

[0008] Preferably, the height adjustment assembly includes a nut fixedly arranged on the bottom wing plate of the channel steel; a screw is arranged inside the nut; and a disc is fixedly arranged after the end of the screw passes through the bottom wing plate of the channel steel. The arrangement of the screw and the nut facilitates the adjustment of the height of the channel steel. The arrangement of the disc increases the contact area with the base surface of the site and ensures the stability of the height setting of the channel steel.

[0009] Preferably, the mounting seat is hingedly arranged on the channel steel wing plate. The hingedly arranged mounting seat facilitates the storage of the concrete surface elevation control bracket when not in use.

[0010] Preferably, the mounting seat is arranged on the channel steel through two round tubes 1; the mounting seat includes round tube 2; two L-shaped rods are fixedly arranged on the outer wall of round tube 2; the two L-shaped rods are symmetrically arranged; the ends of the L-shaped rods are hinged in round tube 1; the two round tubes 1 are respectively fixedly arranged on the two wing plates of the channel steel; the positioning rod is arranged in round tube 2. The hinged arrangement of the mounting seat is completed.

[0011] Preferably, the length of the second round tube is less than the distance between the two wing plates of the channel steel. After the second round tube rotates around the hinge of the L-shaped rod and the first round tube, it can be placed between the two wing plates of the channel steel, reducing the volume occupied and facilitating storage.

[0012] Preferably, the connection assembly includes two round tubes three; the round tubes three are fixedly arranged on the wing plates of the channel steel. The channel steels of two adjacent concrete surface elevation control brackets can be connected by threaded steel bars inserted into the round tubes three.

[0013] The beneficial effect of the utility model is that by setting the height adjustment component, the height of the channel steel can be adjusted and checked in time during the construction process, avoiding the impact of knocking out the wedge-shaped fixing pin on the height of the adjacent channel steel, thereby ensuring high construction quality.
