Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a concrete precast block formwork with a groove for fixing pieces of doors and windows. Background Art

[0002] When installing doors and windows, in the case of no plastering or thin plastering on the inner and outer sides of the door and window frames, the doors and windows can be reliably connected to the main body by driving the fixing pieces into the grooves, with less wet work and risks of hollowing and cracking. The groove position is leveled with polymer anti-cracking mortar, which is both energy-saving and environmentally friendly.

[0003] However, it still has the following disadvantages in actual use:

[0004] When manufacturing precast blocks with the existing concrete precast block formwork with a groove for fixing pieces of doors and windows, it is necessary to put concrete into the formwork and compact the concrete with a trowel. When using the trowel, it is necessary to insert a tamper into the formwork to drive the trowel. However, when inserting the tamper into the concrete, it needs to be kept vertical and not tilted. Generally, the tamper is held manually, and it cannot be guaranteed to be completely vertical, which affects the compaction effect. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a concrete precast block formwork with a groove for fixing pieces of doors and windows to solve the problem proposed in the above background art that when manufacturing precast blocks with the existing concrete precast block formwork with a groove for fixing pieces of doors and windows, it is necessary to put concrete into the formwork and compact the concrete with a trowel. When using the trowel, it is necessary to insert a tamper into the formwork to drive the trowel. However, when inserting the tamper into the concrete, it needs to be kept vertical and not tilted. Generally, the tamper is held manually, and it cannot be guaranteed to be completely vertical, which affects the compaction effect.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0016] Compared with the prior art, the advantages of the present utility model are as follows:

[0017] 1. In the present utility model, by rotating the rotating shaft to rotate the movable plate to close one side of the movable plate of the template, after installing the first limiting rod to fix the movable plate, concrete is poured into the template. After pouring to an appropriate height, the height of the sliding plate is manually adjusted and slowly moved from top to bottom.

[0030] Please refer toFigures 1-3 As shown in the figure, this embodiment is a formwork for concrete precast blocks with a grooved window and door fixing piece, including:

[0031] The main body mechanism 1, the main body mechanism 1 includes a formwork 101;

[0032] The concrete is shaped by combining the formwork 101 with the movable plate 102;

[0033] The horizontal mechanism 2, the horizontal mechanism 2 includes a sliding plate 201 slidably connected to the inner cavity of the formwork 101. The two sliding plates 201 are vertically arranged. A chute 202 is provided on the inner wall of the sliding plate 201. A support rod 203 is slidably connected to the inner cavity of the chute 202. A sleeve 204 is sleeved on the outer wall of the end of the support rod 203;

[0034] The support rod 203 is driven to move by the sliding plate 201. The support rod 203 can move horizontally through the chute 202. The connecting frame 301 is driven to move by the support rod 203. The support rod 203 is extended or shortened through the sleeve 204;

[0037] The sliding plate 201 is limited by inserting the second limiting rod 402 into the limiting hole 401;

[0038] Working principle: The movable plate 102 is rotated through the rotating shaft 105 to close one side of the movable plate 102 of the formwork 101. After installing the first limiting rod 103 to fix the movable plate 102, concrete is poured into the formwork 101. After pouring to an appropriate height, the height of the sliding plate 201 is manually adjusted and slowly moved from top to bottom. Every time it moves one section, the second limiting rod 402 is inserted into the limiting hole 401 to limit the sliding plate 201. The sliding plate 201 drives the support rod 203 to move vertically. When compacting the concrete, it needs to shrink from the outer circle to the inner circle.
