It is stated that, the drawings all adopt very simplified form and all use non-precise proportion, just to facilitate, clear and assist the purpose of explaining the embodiment of the utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0026] A kind of building construction formwork tooling, as Figures 1 to 8 As shown in the figure, including cross rod piece 1, the bottom of the cross rod piece 1 is sequentially provided with first clamping body 2, second clamping body 3, third clamping body 4 and fourth clamping body 5 in vertical, the space for clamping a formwork is formed between first clamping body 2 and second clamping body 3, the space for clamping another formwork is formed between third clamping body 4 and fourth clamping body 5, the top of the cross rod piece 1 is vertically provided with guide column 6, and impact hammer 7 is movably sleeved on the outer wall of guide column 6 in vertical.

[0027] The bottom of first clamping body 2, second clamping body 3, third clamping body 4 and fourth clamping body 5 is provided with arc-shaped guide portion 8, and the guide portion 8 on first clamping body 2 and the guide portion 8 on second clamping body 3 form a spade shape, and the guide portion 8 on third clamping body 4 and the guide portion 8 on fourth clamping body 5 form a spade shape. The longitudinal section of the cross rod piece 1 is inverted T-shaped.

[0028] The top middle part of the cross rod piece 1 is horizontally provided with bearing disc 9, and the top middle part of bearing disc 9 is connected with guide column 6. The cross section of guide column 6 is rectangular, and impact hammer 7 is movably attached to the outer wall of guide column 6, and operating handle 10 is horizontally provided on the side of impact hammer 7. The top of guide column 6 is horizontally provided with anti-drop portion 11, and the projection of anti-drop portion 11 in vertical direction overlaps with the projection of impact hammer 7 in vertical direction. The top of anti-drop portion 11 is vertically provided with operating lever 12, and the top of operating lever 12 is provided with anti-skid portion 13 with a larger diameter than operating lever 12.

[0029] A first sliding sleeve 14 and a second sliding sleeve 15 are horizontally and movably sleeved on the cross bar 1. The inner sides of the first sliding sleeve 14 and the second sliding sleeve 15 are fitted to the outer wall of the cross bar 1. The top of the second clamping body 3 is fixedly connected to the bottom of the first sliding sleeve 14. The top of the fourth clamping body 5 is fixedly connected to the bottom of the second sliding sleeve 15. A linkage part 16 is arranged between the sides of the first sliding sleeve 14 and the second sliding sleeve 15. A positioning cylinder 17 is vertically arranged on the top of the first sliding sleeve 14. A first hole body 18 is vertically formed through the top of the first sliding sleeve 14. A second hole body 19 is formed in the top of the cross bar 1. A positioning rod 20 is vertically arranged in the positioning cylinder 17. There is a set pressure between the positioning rod 20 and the positioning cylinder 17. When the positioning rod 20 is inserted into the first hole body 18 and the second hole body 19, the positioning rod 20 fixes the first sliding sleeve 14 and the cross bar 1, and the top of the positioning rod 20 is higher than the positioning cylinder 17.

[0030] Two long strip-shaped stabilizing parts 21 are horizontally arranged at the bottom of the cross bar 1. The two stabilizing parts 21 and the cross bar 1 form a "艹" shape. One stabilizing part 21 is located between the first sliding sleeve 14 and the first clamping body 2. The other stabilizing part 21 is located between the second sliding sleeve 15 and the third clamping body 4. The first sliding sleeve 14 abuts against the side of the corresponding stabilizing part 21. A terminating part 22 is arranged at the top of one end of the cross bar 1. When the second sliding sleeve 15 abuts against the terminating part 22, the first sliding sleeve 14 and the second sliding sleeve 15 are respectively in a separated state from the corresponding stabilizing parts 21.

[0031] For a formwork support tooling provided by the utility model, after the formwork is vertically placed and inclined struts are connected to both sides, workers only need to move the cross bar 1 to the tops of the two formworks, then align one formwork between the first clamping body 2 and the second clamping body 3, and align the other formwork between the third clamping body 4 and the fourth clamping body 5. Then, press the cross bar 1 vertically downward. And during this process, the worker can also raise the impact hammer 7, then release the impact hammer 7 or drive the impact hammer 7 downward, and apply a large downward impact force to the cross bar 1 through the impact hammer 7, so that the two formworks are stably clamped. After the two formworks are clamped, the worker takes out the wooden board and fits the wooden board on the tops of the two formworks, and finally nails the wooden board and the formworks together with nails; the wooden board is relatively close to the cross bar 1, so the distance between the formworks at the position of the wooden board is better at this time. Therefore, there are not too many requirements for the position and length of the wooden board during actual use, as long as the wooden board can cover the two formworks, and the operation effect is better. After the wooden board is nailed tightly, move the cross bar 1 upward to separate it from the formworks, and the operation is simple and convenient.

[0032] Wherein in the process of moving the cross bar 1 downward, the template can be better clamped into the corresponding position by the action of the guide part 8, so that in actual use, even if the template is deformed or bent, the template can be better driven to the accurate position by the guide part 8, so that the worker only needs to move the cross bar 1 downward, and the operation is convenient. At the same time, the worker applies a vertical downward force when operating, which can well prevent the worker from being affected by the reaction force of the template when horizontally affecting the template, that is, the position stability of the worker is ensured, and the operation safety is improved.

[0033] When the template is clamped between the first clamping body 2 and the second clamping body 3, and between the third clamping body 4 and the fourth clamping body 5, because the template and the clamping body (first to fourth, same below) have a certain friction, after the worker moves the impact hammer 7 upward and then downward, the cross bar 1 is driven downward by the impact hammer 7 until the last stabilizing part 21 is attached to the top of the template, at this time the position of the template reaches the appropriate, and the stabilizing part 21 has a certain length, so the stabilizing part 21 can improve the angle and position stability of the cross bar 1 and the clamping body, at this time the worker can completely loosen the cross bar 1 to perform the operation of taking the board and nailing.

[0034] Wherein the impact hammer 7 can be operated by the operating rod 12, and the operation is more convenient; secondly, because the cross section of the guide column 6 is rectangular, the angle of the impact hammer 7 can be ensured, and the operating rod 12 can be conveniently operated. In the subsequent movement and storage process of the tooling, the anti-disengagement part 11 can prevent the impact hammer 7 from being separated from the guide column 6; and the operating rod 12 can be used to stabilize and move the cross bar 1 during operation, and the anti-slip part 13 can prevent the worker's hand from slipping off the operating rod 12, thereby improving the operation stability. When the impact hammer 7 impacts downward, it impacts the larger area bearing disc 9, so that the cross bar 1 can be well prevented from being deformed. At the same time, the bearing disc 9 is located directly above the middle position of the two templates, so that the situation of being stuck with the template can be well prevented. At the same time, the longitudinal section of the cross bar 1 is inverted T-shaped, so that the cross bar 1 has greater strength, thereby ensuring the service life and use stability of the tooling.

[0035] When the nailing of the wood board is completed, the worker raises the positioning rod 20 by a certain distance, and makes the bottom of the positioning rod 20 out of the second hole body 19, then moves the linkage 16 towards the termination part 22, at this time the linkage 16 drives the first sliding sleeve 14, the second sliding sleeve 15, the second clamping body 3 and the fourth clamping body 5 to move towards the termination part 22, until the second sliding sleeve 15 abuts against the termination part 22, at this time the tooling can be separated from the formwork conveniently. After the separation, the linkage 16 is moved reversely until the first sliding sleeve 14 abuts against the corresponding stabilizing part 21, then the positioning rod 20 is pressed downwards so that the positioning rod 20 is inserted into the second hole body 19, at this time the tooling returns to the standby state. The positioning rod 20 and the positioning cylinder 17 have a certain friction force, so that the positioning rod 20 can be prevented from being separated from the positioning cylinder 17, and the positioning effect of the positioning rod 20 on the first sliding sleeve 14 is improved. Meanwhile, the friction force between the two is not very large, so that the worker can move the position of the positioning rod 20 manually.
