Abstract
The utility model belongs to the technical field of tools for manufacturing PC boards (the factory-like prefabricating and assembling technology of cement products), and particularly relates to a threaded blind hole forming bar which comprises a core bar body and a head. The core bar body is a cone body, threads are arranged on the outer surface of the core bar body, the thread pitch of the threads is 20-40 mm, the depth of the threads is 1-6 mm, a first grout hole forming bar threaded hole is formed in the position, 20-40 mm away from the top end of the core bar body, of the core bar body, a second grout hole forming bar threaded hole is formed in the position, 100-140 mm away from the first grout hole forming bar threaded hole, of the core bar body, and the cross section of the first grout hole forming bar threaded hole and the cross section of the second grout hole forming bar threaded hole are located on the same plane. A through hole is formed in the end portion of the head. The threaded blind hole forming bar is convenient to locate when being used and is convenient to take out when being dismounted.
Description
Technical field
The utility model belongs to PC plate (cement products batch production prefabricated and assembling technique) manufacture field and uses apparatus technical field, relates in particular to a kind of tapped blind hole moulding stick.
Background technology
PC plate (cement products batch production prefabricated and assembling technique) is when assembled, exposing in the blind hole that muscle will be arranged on latter of last block of plate, grouting sealing again after installing, the moulding that starts this hole is to require position to place one section of bellows at PC plate, in order to reduce production costs, do afterwards a kind of device (205 millimeters of the forming hole degree of depth) and replaced this hole of corrugated pipe forming, this device wraps up a cover exactly on a plug, this cover is divided into pintongs, while facilitating plug to take out, the cover of parcel also can take out, on the cover of coated outside, process a-circle-by-a-circle lines, this lines can make the hole of moulding produce larger frictional force, but in use, the plug of this device is difficult to take out, reason is the cover that wraps up on plug because the effect of cement mortar makes its being bonded together tightly, all to take to beat at every turn, rotation, support such as draws could take out at the way.And in order to make moulding stick fixing on mould, employing mode is at a nut of one end of plug welding.The nut direction of the welding of this class, position all cannot be fixed.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, and a kind of location of being convenient to is in use provided, and is convenient to the tapped blind hole moulding stick of taking-up during dismounting, and its technical scheme is as follows:
Tapped blind hole moulding stick, it is characterized in that, described tapped blind hole moulding stick comprises plug and termination, described plug is a cone, the outer surface of plug is provided with screw thread, the pitch of screw thread is 20-40mm, the degree of depth of screw thread is 1-6mm, on plug, 20-40mm place, distance plug top offers the first grout hole moulding stick screwed hole, on plug, distance the first grout hole moulding stick screwed hole 100-140mm place offers the second grout hole moulding stick screwed hole, and the cross section of the first grout hole moulding stick screwed hole and the second grout hole moulding stick screwed hole is in the same plane; The end of described termination offers through hole.
Optimal way is that described termination is provided with keeper, offers the mounting-positioning holes of two symmetries on described keeper.
The tapped blind hole moulding stick that the utility model provides, described plug is a cone, can be so that plug reduces and the contact-making surface of cement mortar by cone.And the outer surface of plug is provided with screw thread, by the cooperation of screw thread and cone, can be so that the contact-making surface of plug and cement mortar reduces, when needs are removed, only need to knock lower plug, then rotate plug, by the motion of screw thread, take out moulding stick, make the taking-up of moulding stick very convenient laborsaving, do not need to use other machines equipment.The first grout hole moulding stick screwed hole and the second grout hole moulding stick screwed hole are to use for grout hole moulding stick is installed.The through hole of termination, for plugging steel pole and so on, can utilize lever principle to make the dismounting of plug more laborsaving.And further, termination is provided with keeper, keeper is provided with mounting-positioning holes, and while making plug be arranged on mould, location is more convenient.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with Fig. 1, illustrate embodiment:
As shown in Figure 1, tapped blind hole moulding stick, described tapped blind hole moulding stick comprises plug 1 and termination 2, described plug 1 is a cone, the outer surface of plug 1 is provided with screw thread 3, the pitch of screw thread is 30mm, the degree of depth of screw thread is 3mm, on plug 1, distance plug 1 30mm place, top offers the first grout hole moulding stick screwed hole 4, it is in the same plane that on plug 1, distance the first grout hole moulding stick screwed hole 120mm place offers the cross section of the second grout hole moulding stick screwed hole 5, the first grout hole moulding stick screwed holes 4 and the second grout hole moulding stick screwed hole 5; The end of described termination 2 offers through hole 6.On termination, be provided with keeper 7, on described keeper 7, offer the mounting-positioning holes 8 of two symmetries.
Moulding stick has been cancelled original shape molding cover, plug is made to the cone of 10 millimeters of taperings, 30 millimeters of cone outside processing pitch, the screw thread that the degree of depth is 3 millimeters (205 millimeters of the forming hole degree of depth), apart from 30 millimeters, top, locating to process the first grout hole moulding stick screwed hole, this the first grout hole moulding stick screwed hole is in order to install grout hole moulding stick, other the second grout hole moulding stick screwed hole and the first grout hole moulding stick screwed hole are at a distance of 120 millimeters, and these two screwed holes in one plane.The fixed form of moulding stick on mould is originally a nut of welding, processes now 100 millimeters of external diameters, the step keeper that thickness is 15 millimeters, and processing two diameters is above 12 millimeters of mounting-positioning holes vertical with grout hole.
During routine use, blind hole moulding stick is arranged on to mould fixed position by keeper and mounting-positioning holes, then grout hole moulding stick is arranged on the first grout hole moulding stick screwed hole and the second grout hole moulding stick screwed hole all right.During dismounting, take off grout hole moulding stick, then knock blind hole moulding stick, blind hole moulding stick is taken out in rotation.
This moulding stick can easily take out once striking gently after molding component, and taking-up and installation only have for original 1/10th time.And there is versatility (the original nut direction of welding, position all cannot be fixed, now location and installation hole is ready-made), and improved efficiency, reduced the standby quantity of moulding stick, reduced cost.
