Description

A new type of height-adjustable building support

technical field

The utility model relates to a building support in the construction field, in particular to a novel building support with adjustable height.

Background technique

In the process of building construction, no matter in the construction of buildings, workshops, roads, bridges, etc., building supports are inseparable. It is necessary to build some supports for pouring reinforced concrete or rubber at the construction site. Currently used The structural design of the building support is unreasonable, its length cannot be adjusted, it is inconvenient to use, and its safety performance is poor. The building supports currently used are mostly wooden supports and steel pipe supports. Wooden brackets are mainly sawn wooden beams as columns for upright support according to the specific height. If the height is lower than the actual height, bricks or wooden plugs are used for adjustment. It is easy to tilt or even fall over, and the height cannot be adjusted in the case of buildings with different heights, resulting in a large amount of wood waste. The steel pipe bracket is formed by connecting steel pipes vertically and horizontally, which can be recycled and used many times. However, due to the non-standard length of the steel pipe, the installation position of the fastener is not fixed, and it is impossible to effectively locate and adjust the height, so that the installation speed is slow and the adjustment takes a long time. In some cases, the steel pipe support cannot meet the use requirements.

Patent application number 201020106709.7, patent name: construction formwork supports adjustable columns. The utility model discloses an adjustable building column, the scheme of which simply adopts the design structure of an adjusting nut and a screw rod.

Detailed ways

The specific embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings. If there are exemplary contents in these embodiments, it should not be construed as a limitation of the present utility model.

As shown in Figure 1-7, the outer diameter of the upper end of the sleeve 3 is threaded, and the outer diameter of the threaded part of the sleeve 3 is smaller than or equal to the inner diameter of the thread of the adjusting nut 2, so that the adjustment nut 2 can be loaded and unloaded. The threaded portion of 3 is provided with sleeve groove 7, and the lower part of the upper threaded part of sleeve 3 is provided with lifting adjustment groove 6 (the lifting adjustment groove can also be set on the upper part of the thread, in the utility model only the lifting adjustment groove 6 is arranged on sleeve 3 The following part is described as an example), and a notch for placing the roller 4 is provided on the outer surface of the sleeve 3 . The inner column 1 can be a solid column or a hollow column, and several positioning holes 11 are drilled on the inner column 1, and a guide groove is provided at the position of the lifting adjustment groove 6 on the corresponding sleeve 3 along the axial direction of the inner column 1, and the guide groove is along the inner column 1. Any side in the axial direction of the column 1 is in the form of teeth. The roller grooves along the axial direction of the outer circular surface of the inner column 1 correspond to the number, shape and position of each group of rollers 4 one by one (the utility model is described as a triangular groove), and the function of the roller grooves is to make the rollers move in the roller grooves, so that The inner column 1 can move up and down axially in the sleeve 3 supported by the roller 4 . The triangular groove on the outer diameter of the inner column 1 is the guide groove when the roller 4 moves, that is, when supporting the movement of the inner column 1, since the roller 4 is in direct contact with the inner column 1, the inner column 1 drives the roller 4 with the roller shaft 5 as the The center of rotation moves in the guide groove, and the three functions of the roller 4 are: reducing resistance (contacting the inner column 1 in a rolling manner, reducing the frictional resistance during the lifting process of the inner column 1), constraining the rotation of the inner column 1 (adjusting the inner column 1 by lifting The constraint of the groove prevents the inner column 1 from rotating during the lifting process) and avoids the shaking of the inner column 1 (the outer top of the roller 4 is in direct contact with the guide groove of the inner column 1, and radially constrains the inner column 1 to prevent the inner column 1 from shaking in sleeve 3).

The tightness of contact between the roller 4 and the inner column 1 can be achieved by adjusting the position of the roller shaft in the roller adjustment groove 10 (the roller shaft is described in the form of a bolt, but the specific embodiment of the utility model is not used to limit the utility model). The rollers 4 of the present embodiment are arranged in groups of three in the same circumferential direction of the sleeve 3 (two groups and two groups are arranged alternately in the circumferential direction, or groups of four or more rollers 4 can be implemented in groups. The utility model sets forth the utility model with three rollers, and the specific embodiment is not used to limit the utility model), the purpose of the roller 4 setting is to reduce resistance, constrain the rotation of the inner column 1 and avoid the shaking of the inner column 1. When the inner column 1 is adjusted to the maximum height, there should be at least two sets of rollers 4 to constrain the radial shaking of the inner column 1 . That is, there should be at least two sets of rollers 4 supporting the inner column 1 within the length of the distance L5. The length L4 of the thread on the sleeve 3 should be greater than or equal to the length L3 of the sleeve groove 7, and the length L3 of the sleeve groove 7 should be greater than or equal to the distance L6 between any two adjacent positioning holes 11 on the inner column 1, so that Ensure that the adjusting nut 2 can fully adjust the height of the inner column. The height of the lifting adjustment groove 6 (ie the length of L1) can be set according to the best operating comfort position of the human body (for example, the height of L1 is set to be 1.5 meters, which is convenient for workers to operate.). The length of the lifting adjustment groove 6 is greater than the maximum distance between any two positioning holes 11 on the inner column 1, so that the stroke during adjustment can locate any positioning hole 11 with the positioning pin 8.

The utility model realizes that the height of the building support can be adjusted, and the height adjustment and precise positioning of the support are completed on the building support by a combined adjustment method of coarse adjustment (when the adjustment range is large) and fine adjustment (when the adjustment range is small).

The adjustment method of the utility model scheme is divided into two types: the first one, the coarse adjustment method (realized by positioning the positioning pin 8), which is suitable for high lifting height; the second one, the fine adjustment method (realized by rotating the adjustment nut 2) , suitable for height adjustment of small distances. For example, when the height of the sleeve 3 is not enough to support during the building construction, first use the positioning pin 8 to pass through the lifting adjustment groove 6 and insert it into the positioning hole 11 of the inner column 1, and apply force to the positioning pin 8 to make it move along the sleeve. Move up and down in the lifting adjustment groove 6 of the cylinder 3. When it is adjusted to a roughly suitable position, use another positioning pin 8 to pass through the sleeve groove 7 and the positioning hole 6 on the inner column 1 to fix, then take out the positioning pin in the lifting adjustment groove 6, and then turn the adjusting nut 2 to drive The positioning pin 8 and the inner column 1 carry out height movement to reach the precise position of the required height adjustment, and complete the height adjustment of the building support.
