Abstract
An inside mould for forming a reserved hole of a concrete foundation is characterized by being provided with a barrel-shaped reinforcement cage formed by welding reinforcing steel bars; wherein annular stirrups, which are identical to the peripheral of a section of the barrel-shaped reinforcement cage in terms of shape, are evenly distributed on the wall of the barrel-shaped reinforcement cage along the vertical direction of the barrel-shaped reinforcement cage; vertical reinforcing steel bars are evenly distributed among and connected with the stirrups; and the outer side of the wall of the barrel-shaped reinforcement cage and a barrel opening at one end of the barrel-shaped reinforcement cage are coated by 1-3 layers of 20-60-mesh steel wire gauzes. The barrel-shaped reinforcement cage can be a square-barrel-shaped reinforcement cage. The length of the square-barrel-shaped reinforcement cage is greater than the design length of the reserved hole by 80-100 mm. The length and the width of the section rectangle of the square-barrel-shaped reinforcement cage are greater than the design length of the reserved hole by 5 mm. When the inside mould is used for pouring the concrete foundation for the large equipment, the reserved hole of an embedded foundation bolt can be conveniently made. The inside mould is made of the reinforcing steel bars and the steel wire gauzes; and when secondary grouting is conducted in the reserved hole for embedding the foundation bolt, the combination between the concrete for the secondary grouting and an original concrete foundation is good.
Description
Technical field
When relating to a kind of building operations, the utility model uses aid, particularly a kind of instrument that preformed hole is used on concrete foundation when the concrete foundation of casting large equipment.
Background technology
Main equipment will have concrete foundation when mounted, wants pre-embedded anchoring bolts on concrete foundation, and main equipment is installed on the concrete foundation with stone bolt.For pre-embedded anchoring bolts accurately on concrete foundation, when the concrete foundation of casting large equipment, on concrete foundation, need the position of pre-embedded anchoring bolts to produce the preformed hole that pre-embedded anchoring bolts is used earlier, after treating that concrete foundation is solidified fully, put into stone bolt fluid concrete again in preformed hole, the installation dimension of pressing equipment in preformed hole is pre-embedded anchoring bolts accurately.When making preformed hole, how to guarantee that the preformed hole morpheme correctly is the key of Equipment Foundations construction.In order on concrete foundation, to produce preformed hole, the mould identical with the shape of preformed hole placed in position at preformed hole when casting large equipment concrete foundation, when treating that concrete foundation is solidified to a certain degree, take out mould, after concrete foundation is solidified fully, on concrete foundation, can stay preformed hole.In the prior art, the mould that adopts timber to make the concrete foundation preformed hole is arranged, when the fluid concrete basis, the preformed hole mould of making of timber is placed on the position that needs to make preformed hole, take out mould then, then can on concrete foundation, produce preformed hole.When making the pre-embedded anchoring bolts hole in this way, not to take out the timber mould again after concrete foundation is solidified fully by the time, but when being solidified to a certain degree, concrete foundation takes out the timber mould, with timber Mold Making pre-embedded anchoring bolts hole the time, pretty troublesome, take out the very bad grasp of time of timber mould, the time of taking out the timber mould is too early, cause the pre-embedded anchoring bolts hole to cave in easily, make the shape of preformed hole not reach requirement, the time of taking out the timber mould is late excessively, can cause and take out timber mould difficulty, when if the preformed hole on the concrete foundation is inclined hole, also may be because being limited in of position destroys the concrete foundation main body or can not get the timber mould when taking out the timber mould at all.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose a kind of can the convenience and correctly produce the concrete foundation preformed hole pore-forming inner mold of using in the pre-embedded anchoring bolts hole when the fluid concrete basis
The utility model is realized with the following method.
The tubular reinforcing cage that the useful reinforcing bar welding of concrete foundation preformed hole pore-forming inner mold is made, the barrel of tubular reinforcing cage, vertically be evenly equipped with the identical ring-shaped stirrup of peripheral shape with tubular reinforcing cage cross section along the tubular reinforcing cage, the uniform longitudinal reinforcement that is connected with between the stirrup, the barrel outside and an end nozzle of tubular reinforcing cage are coated with 1～3 layer of 20～60 purpose gauze wire cloth.
Size and dimension of the present utility model should match with the size and dimension of preformed hole on concrete foundation.
When making concrete foundation, after tying up the cage of reinforcement of concrete foundation, before the fluid concrete, the utility model is fixed on the position that needs preformed hole, allow an end nozzle that is coated with gauze wire cloth in inside, propped up template then, fluid concrete in the template chamber again, because the barrel of the tubular reinforcing cage of the present utility model outside is coated with 1～3 layer of 20～60 purpose gauze wire cloth, so concrete mortar can not enter the inner chamber of tubular reinforcing cage, after treating that concrete solidifies fully, form preformed hole at the reinforcing cage place of concrete foundation.
Can produce the preformed hole of pre-embedded anchoring bolts when the concrete foundation of casting large equipment easily with the utility model, particularly the degree of depth is greater than preformed hole 1 meter or that tilt, have more superiority, the utility model is made with reinforcing bar and gauze wire cloth, in the preformed hole of making, during the back-grouting pre-embedded anchoring bolts, the concrete of back-grouting is combined better with former concrete foundation.
Below in conjunction with accompanying drawing, the utility model is further described.
Description of drawings
Fig. 1 cuts open schematic diagram by the master office of looking of a kind of concrete foundation preformed hole pore-forming inner mold of invention scheme proposition of the present utility model;
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
The specific embodiment
Among Fig. 1, Fig. 2, the square tube shape reinforcing cage 1 that the useful reinforcing bar welding of concrete foundation preformed hole pore-forming inner mold is made, the barrel of square tube shape reinforcing cage, along the vertically side of the being evenly equipped with ring-shaped stirrup 2 of tubular reinforcing cage, the uniform longitudinal reinforcement 3 that is connected with between the stirrup, the barrel outside and an end square tube mouth of tubular reinforcing cage are coated with 1～3 layer of 20～60 purpose gauze wire cloth 4.In longitudinal reinforcement, the longitudinal reinforcement external diameter at four jiaos of places is greater than the longitudinal reinforcement on the limit.
Above-mentioned concrete foundation preformed hole pore-forming internal mold has square tube shape reinforcing cage, is suitable for producing on concrete foundation the preformed hole of square-section.When making the utility model, square tube shape length of reinforcing cage of the present utility model is bigger 80～100 millimeters than the design length of preformed hole, and the length and the width of square tube shape reinforcing cage cross section rectangle are bigger 5 millimeters than the design length of preformed hole.
