Abstract
A steel die fastening bolt is composed of a bolt body and a nut, wherein the intermediate portion of the bolt body is provided with a bolt rod, the head portion of the bolt body is provided with a flange which is vertical to the bolt rod, the end portion of the bolt body is provided with a rectangular wedge which is vertical to the bolt rod, and the inner faces of two long sides of the wedge have two slopes. The nut is a wedge frame with a long hole, and two inner long sides of the long hole of the wedge frame are two slopes which are vertical to the wall of the long hole and have the same grade of slope with the slopes of the wedge. The length of the long shaft of the long hole is bigger than the length of the wedge, and the total of the length of the short shaft of the long hole and the width of each slopes equal to the width of the wedge. The wedge frame is locked on the wedge arranged on the end portion of the bolt and can slide up and down along the slopes while being knocked by external forces. The utility model mainly resolves the questions that the current steel die connecting pieces are inconvenient to connect and easy to lose during loading and unloading.
Description
Technical field
The utility model belongs to the connector of building iron template or steel framework bamboo blanket template.
Technical background
The connector of the on-the-spot splicing of existing steel form mainly is following three kinds of forms: 1, the Japanese little punching block U type card that introduce the eighties, this fastener only is suitable for template punching block limit rib in the connection of 2mm with interior typing plate, because of its elasticity jam-packed punching block limit rib by U type card, fastening force is limited, the big mould of steel that is unsuitable for shaped steel limit rib connects, 2, T type pin, this is a SP-70 shaped steel frame bamboo offset plate special connecting piece, form by two board-like tapers, connecting hole on the rib of punching block limit is a slotted hole, needs because of fastening taper operation, the slotted hole that is provided with on the rib of punching block limit can only be vertical with punching block limit rib, this just must cut down the flexural loading height of punching block limit rib, and the installation or removal of two of this connector board-like tapers in addition need be installed respectively from being connected the thing both sides, both operated inconvenience, part is lost, and for these reasons, this connector is not transplanted in the connection application of the big mould of steel all the time.3, bolt connects, and we can say that this is that the big mould of present steel connects unique form, but since the big mould open work of steel environment, wind and weather.Screw thread is corrosion very easily, and is especially easily dead by the cement paste, makes dismounting and extremely inconvenience is installed, and it is not desirable selection equally that therefore existing bolt connects.This shows existing three kinds of types of attachment, is not the on-the-spot desirable accessory that connects of the big mould of steel, suddenly treats the new product replacement.
Technology contents
The utility model mainly is to solve existing steel form connector to connect inconvenience, load and unload the problem of easily losing.
The technical solution of the utility model: the punching block fastening bolt is made up of key and bolt mother, it is characterized in that: the middle part of key is a tightening latch, the bolt head has the edge of a wing perpendicular to tightening latch, the bolt tail is a rectangle voussoir perpendicular to tightening latch, the inner face on the long limits of voussoir two have two domatic, the bolt mother is the wedge frame with slotted hole, long limit is perpendicular to hole wall in two of wedge frame slotted hole, and it is identical with the domatic gradient of voussoir domatic, the major axis of the slotted hole of wedge frame is greater than voussoir length, the minor axis of slotted hole adds the width that domatic width equals voussoir, the wedge frame is stuck on the voussoir of key afterbody, when external force is knocked, can slide up and down along domatic.
The diameter of above-mentioned tightening latch equals the minor axis length of slotted hole.
The edge of a wing of above-mentioned bolt head is cylindrical, square column type or square column globular model.
The import and export that above-mentioned wedge frame cooperates with voussoir forms one and the corresponding chute of voussoir.
Above-mentioned wedging place at slotted hole be expanded into voussoir with wide rectangular opening.Beneficial effect
Traditional bolt connected change key into, the wedge frame pulls out tight joint construction, the on-the-spot installation only needs a top or the bottom that hammer is knocked the wedge frame, can make key pull out tight or withdraws from, and avoided the defective of screwed connection, greatly simplified template attended operation program.Earlier two unit constructions of key and wedge frame are in the same place during connection, the bolt head penetrates connecting hole from a side of punching block limit rib, half-twist, make the bolt head edge of a wing block punching block limit rib, the wedge frame is enclosed within on the voussoir of bolt tail, and wedge frame and voussoir have same domatic, when external force is knocked, can slide up and down and wedging along voussoir, thereby realize function fastening or that throw off.No matter fastening bolt inserts or withdraws from, and two parts always are interlocked, and does not exist T type pin to need by rib both sides, the punching block limit problem of installation and removal respectively, thus accomplish easy and simple to handle, do not lose part.Be applicable to building iron template or steel framework bamboo blanket template.
