Description

Technical Field

[0001] The utility model relates to the technical field of building construction tools and provides an auxiliary tool for installing templates in narrow locations. Background Art

[0002] At present, the installation of beam and column formwork in narrow spaces is generally completed by pre-assembling the formwork, and then the semi-finished formwork is installed at the component position. The position of the semi-finished formwork is fixed by driving nails between the semi-finished formwork and the component, which can effectively improve the preparation speed before concrete pouring.

[0003] During the construction process in a narrow space, the formwork installation process is difficult for workers to operate due to the small space. It is not convenient to use traditional tools such as hammers to directly hit the rear end of the nail to drive the nail in. It is also difficult to straighten the nail during the nailing process, causing the pre-assembled formwork to be deformed during installation and unable to be corrected and adjusted, resulting in problems such as warping of edges and excessive plate joints, which lead to quality problems such as leakage, misalignment, and bulging of the formwork during the later concrete pouring, increasing the cost of rectification and repair. Utility Model Content

[0004] Based on the above technical problems, the present invention provides an auxiliary tool to achieve accurate driving of nails in a narrow space and to adjust the angle of the nails, so as to effectively adjust the formwork and position it, providing a high-quality formwork structure for subsequent pouring.

[0005] In order to achieve the above-mentioned purpose, the utility model provides an auxiliary tool for installing templates in narrow areas, and the technical solution is as follows: it includes a first cylinder, a second cylinder, a first push rod and a second push rod. The first cylinder is fixedly connected to the rear end of the second cylinder, and the two cylinders are coaxially arranged and axially penetrated; the first push rod is slidably arranged in the first cylinder and the rear end extends outward; the front end of the first cylinder is provided with an axial limiter, the second push rod is slidably matched with the through hole of the axial limiter, and the rear end extends into the first cylinder and the front end extends into the second cylinder, and the axial limiter limits the axial sliding range of the second push rod; the second cylinder is provided with a radial clamping piece inside, the nail is inserted from the front end center hole of the second cylinder, and the rear end is clamped and straightened by the radial clamping piece.

[0006] Furthermore, a front retaining ring and a rear retaining ring are respectively provided at both ends of the rod body of the second push rod, and the inner diameter of the through hole of the axial limiting hole is smaller than the outer diameters of the front retaining ring and the rear retaining ring.

[0007] Furthermore, an internal return spring component is disposed between the axial limiting portion and the rear retaining ring of the second push rod, and the internal return spring component applies a thrust force to the second push rod in a direction away from the first cylinder.

[0008] Furthermore, an external return spring member is provided between the first cylinder and the first push rod, and the external return spring member applies a thrust force to the first push rod in a direction away from the second cylinder.

[0009] Furthermore, a hammer seat adapted to a hammer tool is provided at the rear end of the first push rod, and the external return spring member is provided between the hammer seat and the rear end of the first cylinder.

[0010] Furthermore, the radial clamping member includes a plurality of arc-shaped spring sheets, which are evenly distributed in a circle in the second cylinder and convex in the middle to enclose a space through which the rear end of the nail passes.

[0011] Furthermore, the inner wall of the second cylinder is evenly distributed with a plurality of axial grooves in a circumferential manner, and the rear end of each of the arc-shaped spring sheets is fixedly connected to an end of the axial groove close to the first cylinder, and the front end is slidably disposed in the axial groove.

[0012] Furthermore, the stroke of the second push rod in the axial limit portion is greater than the distance from the front end center hole of the second cylinder to the front end surface of the second push rod, and the front end outer diameter of the second push rod is smaller than the aperture of the front end center hole of the second cylinder.

[0013] Furthermore, the front end of the first cylinder is provided with an external thread, and the rear end of the second cylinder is provided with an internal thread engaged with the external thread, and the distance from the front end center hole of the second cylinder to the front end face of the second push rod is adjusted by changing the engagement length of the external thread and the internal thread.

[0014] The beneficial effects of the provided auxiliary tool for installing templates in narrow areas are as follows:

[0015] Use the provided auxiliary tool for installing the template for narrow parts to pass the nail through the front center hole of the second cylinder. The rear end of the nail is straightened by the radial clamp to maintain a coaxial position with the second cylinder. The tail of the nail is pressed against the front end of the second push rod. Then move the auxiliary tool for installation to align the front end of the nail with the position where it needs to be nailed. Adjust the angle of the cylinder so that the nailing direction is adjusted to the appropriate position. Then hammer the first push rod with a hammer.

[0034] In a specific implementation, the stroke of the second push rod 4 in the axial limit portion 11 is greater than the distance from the front end center hole 21 of the second cylinder 2 to the front end surface of the second push rod 4, and the front end outer diameter of the second push rod 4 is smaller than the aperture of the front end center hole 21 of the second cylinder 2.

[0035] A radial clamp is provided inside the second cylinder 2, and the nail 8 is inserted through the front center hole 21 of the second cylinder 2, and the rear end is clamped and straightened by the radial clamp. Specifically, the radial clamp includes a plurality of arc-shaped spring pieces 5, which are evenly distributed in the second cylinder 2 in a circumferential manner and convex in the middle to enclose a space for the rear end of the nail 8 to pass through. The inner wall of the second cylinder 2 is evenly distributed in a circumferential manner with a plurality of axial grooves 22, and the rear end of each arc-shaped spring piece 5 is fixedly connected to one end of the axial groove 22 close to the first cylinder 1, and the front end is slidably arranged in the axial groove 22.

[0038] Then, move the installation auxiliary tool so that the front end of the nail 8 is aligned with the position where it needs to be nailed, and adjust the angle of the cylinder so that the direction of the nail is adjusted to a suitable angle;

[0039] Then, the rear end of the first push rod 1 is hammered with a hammer, so that the first push rod 1 applies an impact force to the second push rod 4, and the second push rod 4 applies a hammering force to the nail 8, thereby accurately driving the nail 8 in.

[0040] The provided auxiliary tool for installing formwork in narrow areas clamps the nails through radial clamps, which not only saves the need to clamp the nails, but also maintains the accuracy of the nail insertion angle and the success rate during the nailing process.
