Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a concrete construction joint construction tool. Background Art

[0002] During the construction of concrete structures, due to technical reasons, the entire concrete structure needs to be constructed in sections, forming construction joints at the joints. The treatment of concrete construction joints is extremely important in building construction and requires the high attention of construction personnel. Construction personnel must adhere to regulatory requirements to ensure the safety, durability, and aesthetics of the concrete wall structure. For example, when pouring the side walls of a basement, concrete needs to be poured in batches, creating a construction joint between the first and last poured concrete. To prevent leakage at the construction joint later, a steel waterstop needs to be placed at the construction joint during pouring to improve the joint's impermeability.

[0003] At present, in the early stage of concrete pouring, the waterstop is generally temporarily fixed by welding longitudinal steel bars. This method has poor positioning effect. The waterstop is easily offset by the impact force of concrete, and the welded longitudinal steel bars are also more troublesome to remove later. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0023] See also Figure 1-4, This embodiment discloses a concrete construction joint construction tool, including a cross bar 1 and a clamping hanger 5. A pair of sliding sleeves 2 are sleeved on the horizontally arranged cross bar 1, and the sliding sleeves 2 can be slid and adjusted along the length direction of the cross bar 1. The sliding sleeves 2 are provided with a fastening device 4, which is used to limit and lock the sliding sleeves 2 on the cross bar 1; a hanger 7 extending vertically downward is fixed on the lower surface of the cross bar 1, and a clamping hanger 5 with a U shape and an opening facing directly downward is fixed on the end of the hanger 7; a clamping mechanism 6 is provided on the clamping hanger 5, and the clamping mechanism 6 is used to clamp and fix the steel plate waterstop 9 in the clamping hanger 5; a clamping hoop 3 is fixed on the two sliding sleeves 2, and the clamping hoop 3 is used to detachably fix the two sliding sleeves 2 to two adjacent longitudinal steel bars 8.

[0024] When using this construction tool for construction, first put the two clamps 3 on the two adjacent longitudinal steel bars 8 above the concrete base 10, and lock the clamps 3 by fastening the screws 301, so that the two sliding sleeves 2 can be fixed on the two adjacent longitudinal steel bars 8 respectively. Since the sliding sleeves 2 are slidingly sleeved on the cross bar 1, the cross bar 1 and the sliding sleeves 2 can be adjusted to slide relative to each other, so that the hanging rod 7 and the clamping hanger 5 are adjusted to the desired position, and then the fastening device 4 is operated to lock the sliding sleeves 2 on the cross bar 1 to prevent the sliding sleeves from sliding. 2 randomly shifts, then put the steel plate waterstop 9 into the clamping seat 5, and ensure that the steel plate waterstop 9 is vertical to the ground, then operate the clamping mechanism 6 to clamp and fix the steel plate waterstop 9, and then pour the first layer of concrete until the lower half of the steel plate waterstop 9 is submerged and the upper half of the steel plate waterstop 9 leaks out, so as to facilitate the next pouring. After two adjacent pourings, a construction joint appears between the two concrete pouring layers. The steel plate waterstop 9 can be used to intercept the construction joint, which has a good anti-seepage and waterproof effect on the construction joint.

[0025] In this embodiment, the crossbar 1 is a square tube, and the cross-section of the inner cavity of the sliding sleeve 2 is rectangular to match the crossbar 1. The use of the square tube in combination with the rectangular inner cavity can serve as a limiting guide for the sliding sleeve 2, ensuring that the sliding sleeve 2 can only slide and adjust along the length of the crossbar 1, preventing the sliding sleeve 2 and the crossbar 1 from rotating relative to each other, which would cause the hanger 7 and the clamping hanger 5 to swing, further improving the positioning effect of the steel plate waterstop 9.

[0026] In this embodiment, the fastening device 4 includes a fastening bolt A401. The top surface of the sliding sleeve 2 is provided with a threaded hole A402 extending vertically downward and communicating with the inner cavity thereof. The fastening bolt A401 is threadedly installed in the threaded hole A402, and the threaded end of the fastening bolt A401 extends into the inner cavity of the sliding sleeve 2 and contacts the crossbar 1. By pinching the outer end of the fastening bolt A401 and tightening the fastening bolt A401, the fastening bolt A401 will extend into the inner cavity of the sliding sleeve 2 and contact the outer wall of the crossbar 1, thereby limiting and locking the sliding sleeve 2 and the crossbar 1, ensuring that the sliding sleeve 2 will not slide or deviate along the crossbar 1 at will, ensuring the positioning effect of the steel plate waterstop 9, and simple and convenient operation.

[0027] In this embodiment, the clamping mechanism 6 includes a fastening bolt B601, and the two sides of the clamping mount 5 are symmetrically provided with through-shaped threaded holes B602; the fastening bolt B601 is correspondingly threadedly installed in the threaded hole B602 and passes through the threaded hole B602; the clamping disc 603 is correspondingly fixed on the end of the fastening bolt B601 extending into the clamping mount 5. The steel plate waterstop 9 is placed in the clamping mount 5 and located between the two clamping discs 603, and the position of the steel plate waterstop 9 is fine-tuned, and then the fastening bolt B601 is rotated to tighten it. The two fastening bolts B601 push the two clamping discs 603 closer to each other, clamping the steel plate waterstop 9 to achieve a fixing effect. Secondly, the outer diameter of the two clamping discs 603 is larger than the outer diameter of the fastening bolt B601, which increases the contact area with the outer surface of the steel plate waterstop 9, ensuring that the steel plate waterstop 9 can be fixed more firmly, and at the same time helps the steel plate waterstop 9 to remain perpendicular to the ground.

[0028] In this embodiment, the inner wall of the clamp 3, where it contacts the outer wall of the longitudinal steel bar 8, is provided with anti-slip grooves. After the clamp 3 is placed on the longitudinal steel bar 8 and tightened using the fastening screws 301, the anti-slip grooves on the inner wall of the clamp 3 contact the outer wall of the longitudinal steel bar 8, enhancing the friction between the two, ensuring the secure fastening of the clamp 3 to the longitudinal steel bar 8 and preventing the clamp 3 from slipping along the outer surface of the longitudinal steel bar 8.

[0029] In addition to this embodiment, the suspension rod 7 adopts an adjustable telescopic rod, and the clamping hanger 5 is fixed to the end of the telescopic end of the suspension rod 7. Using an adjustable telescopic rod as the suspension rod 7 facilitates the adjustment of the height of the clamping hanger 5, thereby facilitating the adjustment of the installation height of the steel plate waterstop 9, which is suitable for different construction requirements and further improves the practicality of the device.

[0030] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
