Description

Technical Field

[0001] The utility model relates to the technical field of template support, and more specifically to an adjustable supporting device for building templates. Background Art

[0002] Formwork support refers to the formwork support structure used for cast-in-place concrete construction in buildings. It is generally assembled from steel or wooden beams into formwork brackets, which are supported by scaffolding built with steel or wooden poles, and the formwork is used to carry out concrete construction. When supporting the bottom of the formwork, construction workers often use adjustable supports, which are mainly composed of screws, nuts, and U-shaped top supports. When in use, the screws are inserted into the steel pipes, and the nuts are sleeved on the top of the steel pipes. The square wood is then fixed in the U-shaped top support. The square wood plays the role of transmitting the supporting force of the U-shaped top support. The steel pipes are then erected to make the square wood contact with the bottom of the formwork. The nuts are turned to raise the screws and the U-shaped top support so that the square wood is in close contact with the bottom of the formwork to complete the support.

[0003] However, the U-shaped top support equipped with the existing adjustable support cannot fix the square timber. When installing the square timber, construction workers mostly nail iron nails into the square timber and then bend the iron nails until they contact the U-shaped top support to fix the square timber. This is inconvenient to operate and will affect the construction speed. Therefore, it is urgent to design an adjustable support device for building formwork to solve the above problems. Utility Model Content

[0008] Furthermore, the locking assembly includes a strip plate, a pressure rod, a second spring, and two triangular clamping blocks. Two second sliding grooves are opened on the top of the placement plate. The two strip plates are slidably installed in the two second sliding grooves respectively. The pressure rod is fixedly installed on the top of the strip plate. The second spring is fixedly installed between the bottom of the strip plate and the inner wall of the second sliding groove. The two triangular clamping blocks are symmetrically fixedly installed on the top of the strip plate.

[0027] Specifically, the locking assembly 5 includes a strip plate 501, a pressure rod 502, a second spring 503, and two triangular blocks 504. Two second slide grooves 303 are provided on the top of the placement plate 301. The two strip plates 501 are slidably installed in the two second slide grooves 303 respectively. The pressure rod 502 is fixedly installed on the top of the strip plate 501. The second spring 503 is fixedly installed between the bottom of the strip plate 501 and the inner wall of the second slide groove 303. The two triangular blocks 504 are symmetrically fixedly installed on the top of the strip plate 501. Two slots 405 are provided on the bottom of the two splints 401, and the triangular blocks 504 are adapted to the slots 405.

[0028] In this embodiment, in the initial state, the two second springs 503 are both in a released state, and the triangular clamping block 504 is engaged in the clamping slot 405 .

[0029] Specifically, the clamping assembly 4 further includes two pull rods 407 . The ends of the two clamping plates 401 that are away from each other are each provided with an empty slot 406 . The two pull rods 407 are respectively fixedly installed in the two empty slots 406 .

[0030] In this embodiment, when it is necessary to remove the square wood, the pull rod 407 is pulled to pull the clamping plate 401 away from the square wood.

[0039] Working principle: When in use, place the square wood from top to bottom on the top of the placement plate 301. During the falling process, the square wood will first contact the two pressure rods 502 and press the two pressure rods 502 to slide downward, thereby pressing the two strip plates 501 to slide downward in the two second slide grooves 303 respectively. The downward sliding of the two strip plates 501 will drive the four triangular blocks 504 to slide downward and compress the two second springs 503. When the four triangular blocks 504 slide downward to disengage from the four slots 405, the two clamps 401 will be unlocked. At this time, the two first springs 403 will contract, pulling the two sliders 402 to slide close to each other in the first slide groove 302. The sliding of the two sliders 402 close to each other will drive the two clamps 401 to approach each other and clamp the square wood.
