Novel height-adjustable building bracket

Abstract

The invention discloses a novel height-adjustable building bracket which comprises an inner cylinder (1) and a sleeve (3), wherein the inner cylinder (1) is mounted in the sleeve (3); a positioning pin (8) passes through a lifting adjusting slot (6) and is inserted into a positioning hole (11) of the inner cylinder (1); a force is applied to the positioning pin (8) so as to cause the positioning pin (8) to vertically move in the lifting adjusting slot (6) of the sleeve (3); and an adjustable nut (2) is rotated for driving the positioning pin (8) and the inner cylinder (1) to vertically move. Compared with the prior art, the novel height-adjustable building bracket has the beneficial effects: 1, the structure is simple, the adjustability of the vertical column is more convenient, and convenience is brought to field operation of workers; 2, the long-distance adjustment and the short-distance fine adjusting mode can be realized and the working efficiency is increased; and 3, the axial direction and the radial direction of the sleeve and the vertical column are positioned, so that the construction inconvenience caused by the shaking and axial rotating of the bracket during a use process is avoided.

Description

technical field [0001] The invention relates to building supports in the field of construction, in particular to a novel height-adjustable building support. Background technique [0002] 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...

Problems solved by technology

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 screw teeth of the screw rod are exposed outside, the wear of the screw teeth of the screw rod will be aggravated and the service life will be shortened under the harsh environment of the construction site; 4) The column body and the screw rod are matched at intervals, which will cause Shaking and moving, causing inconvenience during loading and unloading

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
