Abstract
The utility model discloses an umbrella-shaped horizontal brace. The umbrella-shaped horizontal brace comprises a vertical rod, upper support arms, lower support arms, a sliding base, a fixed base and a storage barrel. The umbrella-shaped horizontal brace is characterized in that the fixed base penetrates the vertical rod to be fixed at the bottom end of the vertical rod, the sliding base penetrates the vertical rod and can slide vertically along the vertical rod, the upper support arms and the lower support arms in six groups are respectively hinged with the sliding base and the fixed base and are hinged, the length of each upper support arm is twice of that of each lower support arm, the storage barrel is used for storing regularly hexagonal geotechnical cloth provided with holes at six corners, and ends of the upper support arms are inserted into the holes. The closed umbrella-shaped horizontal brace is inserted into a cast-in-place pile before concrete is set initially, the geotechnical cloth is spread by pressing the sliding base after the designed elevation is reached, and then the horizontal brace is closed and taken out. As the geotechnical cloth and the concrete are poor in binding, efficiency in pipe head cutting is greatly improved, damage to rebars and the pile body is reduced, and construction quality is guaranteed.
Description
Technical field:
The utility model relates to filling pile construction, particularly a kind of umbrella horizontal brace.
Background technology:
Castinplace pile has the advantages such as bearing capacity is high, construction technology is ripe, cost is low, is therefore widely used in the basis of industry and civilian construction, bridge.In filling pile construction, because a part of concrete strength of topmost is poor, in order to ensure monolithic concrete intensity, and avoid a top mark height not in place, tend to select perfusion absolute altitude to exceed a top mark high, then abolish unnecessary part.
At present the conventional method of broken pile head is to be manually aided with that small machine cuts or cut concrete cover in the above position of design elevation, make reinforcing bar exposed and peel off concrete, then adopt abrasive machine ring cutting piecemeal cleaning in design elevation position, in an existing broken pile method, mainly have the following disadvantages: 1) pile crown is abolished wastes time and energy, and artificial, machinery expenses is high; 2) when pile crown is abolished, will certainly affect to main muscle, construction quality is difficult to ensure; 3) pile crown is abolished in process and can be caused damage to the pile body below stake top mark height, affects the durability of structure.
Summary of the invention:
The purpose of this utility model is exactly to abolish for current castinplace pile the weak point existing in pile crown construction, develops a kind of umbrella horizontal brace, object be for pile crown abolish provide one fast, effectively, construction means cheaply.
In order to achieve the above object, the utility model by the following technical solutions.
A kind of umbrella horizontal brace, it comprises vertical rod, upper support arm, lower support arm, glide base, fixed pedestal, storage tube, it is characterized in that described fixed pedestal is fixed on vertical rod bottom through vertical rod, described glide base also can slide up and down along vertical rod through vertical rod, establish altogether on 6 groups, lower support arm, respectively with glide base, fixed pedestal is articulated and connected, described upper support arm and lower support arm are articulated and connected, the length that wherein goes up support arm is 2 times of lower support arm lengths, described storage tube is used for depositing regular hexagon geotextiles, the size of regular hexagon geotextiles is determined according to filling pile cage of reinforcement diameter, six angles of geotextiles are reserved with hole, insert for upper support arm end, in castinplace pile, before concrete initial set, insert closed umbrella horizontal brace, after reaching design elevation, press down glide base, make geotextiles horizontal opening, then closed horizontal brace has also taken out laying of geotextiles.
After concrete reaches requirement of strength in castinplace pile, need to carry out place excavation and the above pile crown of stake top mark height is abolished.Because the length of upper support arm is 2 times of lower support arm lengths, so in the process that struts horizontal brace, move in same level upper support arm end, and can be by geotextiles horizontal development, and adhesion stress between geotextiles and concrete is poor, therefore in the time abolishing pile crown, can the concrete column entirety in main muscle be pulled out in stake top mark eminence.
Contrast prior art, the utlity model has following beneficial effect: 1) efficiently abolish pile crown, and time saving and energy saving, and can realize mechanized construction; 2) not only reduced the infringement to main muscle in the time abolishing pile crown, and little to the pile damage below stake top mark height, abolished interface smooth, thereby ensure construction quality.
Brief description of the drawings:
Fig. 1 is that umbrella horizontal brace launches schematic diagram.
Fig. 2 is the closed schematic diagram of umbrella horizontal brace.
In figure: 1, vertical rod, 2, upper support arm, 3, lower support arm, 4, glide base, 5, fixed pedestal, 6, storage tube, 7, geotextiles.
Detailed description of the invention:
Embodiment: the concrete application process that further illustrates umbrella horizontal brace below in conjunction with accompanying drawing.
(1) first umbrella horizontal brace closure, as shown in Figure 2, regular hexagon geotextiles (7) is filled in storage tube (6), outside wherein six angles of regular hexagon geotextiles are reserved in, and upper support arm (2) end is inserted in the reserving hole on six angles of geotextiles.
(2) in castinplace pile, before concrete initial set, closed umbrella horizontal brace is inserted into design of pile top absolute altitude along the central axis of stake, and fixing vertical rod (1).
(3) downward slippage glide base (4), now horizontal brace will be opened as umbrella, and hexagon geotextiles is launched in the horizontal direction completely, as shown in Figure 1, different stake footpaths only need to change the size of geotextiles in the time of construction.
(4) on, propose vertical rod (1), carry glide base (4) on simultaneously, umbrella horizontal brace is extracted.
(5) repeating step (1)～(4), until complete whole pile foundation constructions.
The characteristic of support arm end horizontal slippage in the utilization of umbrella horizontal brace, and the poor geotextiles of concrete binding power insert in pile crown, thereby be conducive to abolishing of pile crown, there is the advantages such as efficient, quick, low cost, and can ensure the construction quality of pile foundation.
