Abstract
Provided is a passing opening clamp for construction of a cast-in-place concrete wall. The passing opening clamp for construction of the cast-in-place concrete wall comprises a lead screw, wherein a blocking part is hinged to the front end of the lead screw, a nut is assembled on the lead screw, radial extension rods are symmetrically arranged on the nut, a sliding chute is formed in each radial extension rod, a pair of connecting rods are connected to the radial extension rods respectively through hinge pins arranged in the sliding chutes, and a U-shaped clamping part is arranged at the outer side end of each connecting rod. The passing opening clamp for construction of the cast-in-place concrete wall is simple in structure, convenient to manufacture, low in manufacturing cost and capable of being repeatedly used, and thus the construction cost can be reduced; when the passing opening clamp is used, assembly and disassembly are easy and convenient, the passing opening clamp can play a great role in fixing wall formworks arranged on the inner side and the outer side and a wall formwork arranged on the passing opening side, and thus efficiency and quality of construction of the cast-in-place concrete wall can be effectively improved.
Description
Technical field
The utility model relates to building operations apparatus, is specifically related to an a kind of in-situ concrete wall construction mouthful card.
Background technology
In the in-situ concrete wall work progress of construction work, need to be fixed body of wall forming panel.Doorway on concrete wall, window waited a mouthful place to be provided with inside and outside both sides and crossed a mouthful side wall form.At present; in in-situ concrete wall construction; generally use the fastening leading screw perpendicular to metope to be fixed crossing mouthful template at place; this fixed form can only solve the fixing of inside and outside two side templates of body of wall; and do not have fixation to crossing the template of mouthful side; therefore, conventionally also will be in crossing mouthful employing strut add and carry on the back the template that the method for wedge crosses mouthful side to body of wall and be fixed.And the template that the method that adopts strut to add carry on the back wedge is crossed mouthful side to body of wall is fixed, troublesome poeration not only, the dress of support, tears open and need to expend a large amount of time, manpower and material, and the poor stability supporting, and has a strong impact on the Forming Quality that body of wall is crossed mouth.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provide a kind of loading, unloading simple and convenient, to inside and outside both sides and the wall form of crossing mouthful side, can play good fixation, can effectively improve in-situ concrete wall efficiency of construction and quality, reduce an in-situ concrete wall construction mouthful card for construction cost.
The technical scheme that realizes above-mentioned purpose is: an a kind of in-situ concrete wall construction mouthful card, there is a leading screw, the front end of this leading screw is hinged a block piece, on described leading screw, be equipped with nut, on this nut, be symmetrical arranged radially extension rod, each radially arranges respectively a chute on extension rod, and pair of links is connected on described radially extension rod by the bearing pin being placed in described chute respectively, and the outboard end of each connecting rod arranges respectively a U-shaped fastener.
Further, the leading screw that described leading screw is hollow-core construction, the leading screw rear end of this hollow-core construction is provided with handle, and the leading screw front end of this hollow-core construction is provided with the front end-plate of leading screw, and described block piece and front end-plate are hinged by rivet.
Further, described block piece is one section of notch towards U-steel above.
The construction of this in-situ concrete wall has following features with crossing a mouthful jig:
1, simple in structure, convenient making, low cost of manufacture, and can reuse, thereby can reduce construction cost;
2, loading, unloading are simple and convenient, to inside and outside both sides and the wall form of crossing mouthful side, can play good fixation, thereby effectively improve efficiency and the quality of in-situ concrete wall construction.
Accompanying drawing explanation
Fig. 1 is this in-situ concrete wall construction mouthful card structure schematic diagram;
Fig. 2 is that the construction of this in-situ concrete wall used a mouthful card to use view.
The specific embodiment
In conjunction with the accompanying drawings and embodiments the specific embodiment of the present utility model is described.
As accompanying drawing 1, the construction of this in-situ concrete wall has a leading screw 1 with crossing a mouthful jig, the front end of this leading screw 1 is hinged a block piece 2, on leading screw 1, be equipped with nut 3, on this nut 3, be symmetrical arranged radially extension rod 4, each radially arranges respectively a chute 5 on extension rod 4, and pair of links 6 is connected to radially on extension rod 4 by being placed in bearing pin 7 in chute 5 respectively, and the outboard end of each connecting rod 6 arranges respectively a U-shaped fastener 8.
Leading screw 1 of the present utility model can be the leading screw of solid construction, the front end of its leading screw can adopt multiple being hinged of structure realization and block piece 2 that be hinged, and the rear end of its leading screw can arrange is convenient to utilize the instruments such as spanner leading screw to be carried out to the structures such as square toes of rotating operation.The leading screw that the leading screw 1 of accompanying drawing embodiment is hollow-core construction, to alleviate its weight.In the rear end of leading screw 1, be provided with handle 9, so that use hand rotational lead screw.Handle 9 can adopt the handle of the various ways such as in-line, cross, annular, and the handle 9 of accompanying drawing embodiment is by steel plate punched moulding, and middle part Cheng Yuan forms the rear end-plate of the leading screw of hollow-core construction, and uniform four convex bodys of circumferential edge, form cross handle.End-plate 10 before the leading screw front end of hollow-core construction is provided with leading screw, block piece 2 and front end-plate 10 are hinged by rivet 11.
Accompanying drawing 2 has provided this in-situ concrete wall construction mouthful use state for card, in use, U-shaped fastener 8 is hooked on respectively to body of wall to be crossed on the fixing horizontal back cord 12 of both walls template of mouth, make the fixing perpendicular back cord 13 of block piece 2 and mistake mouthful side template contact simultaneously, then rotational lead screw 1, make block piece 2 push ahead the thrust producing to crossing mouthful side template, thereby the fastening fixing perpendicular back cord 13 of mouthful side template of crossing, make U-shaped fastener 8 that two horizontal back cords 12 are inwardly strained simultaneously, complete to in-situ concrete wall is crossed mouth inner and outer side template and crossed the fixing of mouthful side template.
The construction of this in-situ concrete wall can adopt coaxial line to be connected with crossing a mouthful connecting rod 6 for card with U-shaped fastener 8, the connecting rod 6 of accompanying drawing embodiment is connected for non-coaxial line with U-shaped fastener 8, the axis of the relative connecting rod 6 of axis of its U-shaped fastener 8 certain angle that turns forward, the non-coaxial line of this kind of connecting rod 6 and U-shaped fastener 8 is connected, and makes U-shaped fastener 8 better with the mated condition of the fixing horizontal back cord 12 of template.
