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. Although this structure solves the problem of the adjustable height of the support to a certain extent in theory, its disadvantages are: The disadvantages are: 1) The adjustable nut and the column with the screw rod need to have higher precision, which will increase the processing and maintenance costs of the bracket; 2) The adjustable nut is slow in large-scale adjustment or loading and unloading, which affects work efficiency ;3) Since the teeth of the screw rod are exposed to the outside, in the harsh environment of the construction site, the wear of the teeth of the screw rod will be aggravated and the service life will be shortened; 4) The column body and the screw rod are matched at intervals, which will cause shaking And moving, inconvenient during loading and unloading. Patent application number 201020260862.5, patent name: a building bracket. The utility model also discloses a height-adjustable building bracket, the structure of which is that a positioning rod is inserted into an inner column, and then the height is adjusted through a casing, a branch pipe and an adjusting ring for adjusting the height of the branch pipe. However, there are the following problems in practical application: 1) If the adjustment design between the branch pipe and the casing is unreasonable, the adjustment will be more inconvenient when the pillar is required to be high, that is, the height adjustment range is limited by the adjustment groove; 2) The bushing and the branch pipe adopt a clearance fit, and can rotate relative to each other in the radial direction, so it is difficult to insert the positioning rod, which affects the work efficiency; 3) The bushing and the branch pipe are not axially fixed and constrained, so that the branch pipe shakes in the casing, Affect the quality of work construction.

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 Figures 1-9, the utility model comprises an inner column 1, an adjusting nut 2, a sleeve 3, a roller 4, a roller shaft 5, a positioning pin 8 and an adjusting handle 9. The outer diameter of one 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 as to facilitate the loading and unloading of the adjusting nut 2. The threaded part of the sleeve 3 is provided with a sleeve groove 7. The lower part of the threaded part of the sleeve 3 is provided with a lifting adjustment hole 6 (the lifting adjustment hole can also be set on the upper part of the thread. In this utility model, only the lifting adjustment hole 6 is set on the lower part of the sleeve 3 is used as an example to illustrate), and the sleeve The outer circular surface of the cylinder 3 is provided with a notch for placing the roller 4 . The inner column 1 can be a solid column or a hollow column. Several radial positioning holes 11 are drilled on the inner column 1, and a guide groove is provided at the position of the lifting adjustment hole 6 on the corresponding sleeve 3 along the axial direction of the inner column 1 to guide Any side of the groove along the axial direction of the inner column 1 is in the form of teeth. The roller groove of the cylindrical surface of inner column 1 along the axial direction corresponds to each group of rollers 4 numbers, shapes and positions one by one (the utility model is set forth with a triangular groove), and the effect of the roller groove is to make the roller move in the roller groove. The roller 4 can reduce the frictional resistance when the inner column 1 moves up and down in the sleeve 3 . The length L3 of the sleeve groove 7 on the sleeve 3 should be greater than or equal to the distance L6 between any two adjacent positioning holes 11 on the inner column 1, so as to ensure that the adjusting nut 2 can fully adjust the height of the inner column. The teeth of the adjustment handle 9 and the teeth of the threaded part on the inner column 1 are in a rack-and-pinion transmission relationship. In order to facilitate the adjustment and loading and unloading of the adjustment handle 9, the diameter of the gear of the adjustment handle 9 should be between the length of L9 and the lifting adjustment. between the diameters of the holes 6. The length L2 of the tooth portion on the inner column 1 should be greater than or equal to the maximum distance between any two positioning holes 11 on the inner column 1, so that the stroke when the adjustment handle 9 rotates can use the positioning pin 8 to locate any one of the positioning holes. Hole 11.

The method of the utility model realizes the height adjustment of the building bracket, and the height adjustment and precise positioning of the bracket are completed on the building bracket 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 the height-adjustable range during construction, first insert the adjustment handle 9 into the lifting adjustment hole 6, turn the adjustment handle 9, and the teeth on the adjustment handle 9 drive the inner column 1 The movement of the upper teeth converts the rotational movement of the adjustment handle 9 into the linear movement of the inner column 1 to complete the height adjustment of the lift. When it is adjusted to a suitable position, use the positioning pin 8 to pass through the sleeve groove 7 and the positioning hole 6 on the inner column 1 to fix it, and then turn the adjusting nut 2, and the adjusting nut 2 drives the positioning pin 8 and the inner column 1 to move up and down , to achieve the precise position of the required adjustment height, and complete the height adjustment of the building support.
