Abstract
The utility model discloses a novel preformed hole construction fixture, which comprises a long rod, a spiral rib and a spiral groove are arranged on the outer surface of the long rod axially and arranged at interval axially, the outer surface of the long rod is tapered axially, and a rotary head is arranged at one end of the long rod of the larger outer diameter, and provided with a radial through hole. The novel preformed hole construction fixture is simple in structure, easy to manufacture, convenient to use and low cost, and can not only simplify complicated preformed hole construction processes but enhance adhesion force between secondary cast concrete of a preformed hole and the wall thereof in a doubled manner, thereby guaranteeing anchoring strength of foundation bolt and stability in normal running of equipment, and being high in practicability and easy to popularize and apply.
Description
Technical field
The utility model belongs to the building trade technical field of construction, relates in particular to a kind of novel preformed hole construction mold.
Background technology
The preformed hole construction is one makes the very work of headache of industrial construction civil engineering, its choice of construction method directly has influence on the normal operation of the anchoring strength of stone bolt and the back equipment of going into operation, it is more smooth that hole wall is reserved in traditional wooden model supporting, the adhesion stress of secondary pouring concrete and hole wall was relatively poor after stone bolt was installed, and withdrawing pattern is difficulty comparatively, the construction of especially dark small bore preformed hole, extremely difficult especially.
The utility model content
The utility model provides a kind of novel preformed hole construction mold in order to solve weak point of the prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: novel preformed hole construction mold, comprise long pole, and the long pole external surface is provided with spiral helicine fin and groove in the axial direction, and fin and groove are provided with in the axial direction at interval.
Described long pole external surface has tapering in the axial direction, and wherein the bigger end of external diameter is provided with rotary head, and rotary head is provided with through hole radially.
Described long pole is that plastic material, inside are cavity structure.
Adopt technique scheme, earlier long pole is placed on the preformed hole construction location, carrying out a concrete then builds, because the long pole external surface is provided with spiral helicine fin and groove in the axial direction, when concrete is about to initial set, the through hole that inserts radially with cross bar unscrews a circle long pole, solidifying along with concrete then, unscrew a circle long pole every a period of time, up to fully long pole being screwed out, preformed hole edge behind the back-out long pole is shape groove and fin in the shape of a spiral, can increase the adhesion stress between grouting material (or secondary is built concrete) and the hole wall when secondary is built; The long pole external surface has tapering in the axial direction, is convenient to easily outwards unscrew withdrawing pattern, and rotary head is used to rotate long pole, and the radial direction through hole on the rotary head is used to insert a cross bar, and rotating horizontal pole realizes unscrewing the withdrawing pattern operation like a cork; Long pole is a plastic material, inner for cavity structure, in light weight, fully reduces manufacturing cost.The utility model is simple in structure, be easy to make, easy to use, with low cost, not only can oversimplify the preformed hole construction sequence of complexity, and the preformed hole secondary that has been multiplied is built the adhesion stress between concrete and the hole wall, be enough to ensure the anchoring strength of stone bolt, guarantee the stability of the normal operation of equipment, practical, be easy to apply.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is to use the utility model to build the schematic diagram of preformed hole behind the concrete.
The specific embodiment
As shown in Figure 1 and Figure 2, novel preformed hole construction mold of the present utility model, be included as the long pole 1 of plastic material, long pole 1 inside is cavity structure (being that long pole 1 inside is axially arranged with columned cavity 2), long pole 1 external surface is provided with spiral helicine fin 3 and groove 4 in the axial direction, and fin 3 and groove 4 are equidistant at interval in the axial direction to be provided with, and fin 3 and groove 4 equidistantly are provided with in the axial direction, not only make things convenient for processing and manufacturing, and be convenient to operation.Long pole 1 external surface has tapering in the axial direction, and wherein the bigger end of external diameter is provided with rotary head 5, and rotary head 5 is provided with through hole 6 radially.The utility model during fabrication can be one-body molded.
During use, earlier long pole 1 vertically is placed on the preformed hole construction location, carry out one-time-concreting concrete 7, because long pole 1 external surface is provided with spiral helicine fin 3 and groove 4 in the axial direction, along with solidifying of concrete 7, insert cross bar in the through hole 6 on rotary head 5, unscrew a circle cross bar every a period of time, after long pole 1 is screwed out concrete 7, edge shape groove 8(in the shape of a spiral cooperates with fin 3) and fin 9(cooperate with groove 4) preformed hole 10 moulding, owing to have helical groove 8 and fin 9 in the preformed hole 10, when secondary is built, can increase secondary and build adhesion stress between concrete and the hole wall, ensure the anchoring strength of stone bolt, guarantee the stability of the normal operation of equipment.
Claims (3)
