Abstract
A mortise grouting type connector of prefabricated structures comprises concrete precast blocks, mortises and tenons which are meshed with each other are disposed on the joints of the concrete precast blocks, a gap for grouting is reserved between the mortises and the tenons, grouting holes communicated with the gap are disposed in the concrete precast blocks, sealing strips are arranged in the two ends of the gap, and grout is poured into the gap. The mortises and the tenons may be in single tenon, double tenon or multiple tenon type. The beneficial effects of the mortise grouting type connector are that the mortise-tenon type connector is convenient to connect and simple in construction technique; with the occlusion effect of the mortises and the tenons, a shearing force can be effectively transmitted, and the axial force transmission is not impacted; and after the gap between the mortises and the tenons is grouted, relative displacement deformations between the mortises and the tenons can be effectively restrained, concrete of the joined faces can be reliably bonded so as to sustain the internal force of the concrete components and limit the opening of the gap, and the grouting material also plays an excellent connector waterproof effect.

The pattern that prefabricated costruction member connected in the past mainly comprises that tongue-and-groove plug-in type, planar end surface bolt connecting type, step, local cast-in-place (concrete) formula, welded type etc. are multiple, and these methods are used for the connection of small-scale (scale of construction) or stressed simple prefabricated units.And large scale prefabricated assembling underground structure need experience complicated internal force transfer process in construction period, and butt joint waterproof requirement is high, is necessary to adopt more reliable and more stable joint connection manner.
Utility model content
The purpose of this utility model is to provide a kind of prefabricated assembly structural tongue-and-groove grouting formula joint, it has promoted the reliability of fabricated construction jointing, propose one and be connected to basis with tongue-and-groove plug-in type, carried out the Novel joint mode of reinforcing joint connection reliability and non-deformability with placing bonding slurries in joint leakage.
For achieving the above object, the utility model is taked following technical scheme:
A kind of prefabricated assembly structural tongue-and-groove grouting formula joint, it includes concrete precast block, tongue-and-groove and the tenon of mutual interlock are set respectively in the joint of concrete precast block, in the middle of tongue-and-groove and tenon, leave the space of reperfusion serosity, on concrete precast block, be respectively equipped with the grout hole being communicated with space, two ends in space are provided with weather strip, reperfusion serosity in space.
As preferably, described tongue-and-groove and tenon are single tenon forms.
As preferably, described tongue-and-groove and tenon are double tenon forms.
As preferably, described tongue-and-groove and tenon are many tenons forms.
The beneficial effects of the utility model are:
(1) tongue-and-groove, tenon head type joint are easy to connect, and construction technology is simple;
(2) tongue-and-groove, tenon head type connect the effectively Transfer of Shear of interlocking of utilizing rebate, and its axle power is transmitted unaffected;
(3) after tongue-and-groove, the grouting of tenon gap, can effectively limit the distortion of relative shift between tenon tongue-and-groove, the also reliable concrete at bonding connection interface, the internal force of the concrete component that continues, opening of restriction seam, grouting agent can also play good joint waterproofing effect simultaneously.

Detailed description of the invention
Shown in Figure 1: a kind of prefabricated assembly structural tongue-and-groove grouting formula joint, it includes concrete precast block, tongue-and-groove 1 and the tenon 2 of mutual interlock are set respectively in the joint of concrete precast block, in the middle of tongue-and-groove and tenon, leave the space 3 of reperfusion serosity, on concrete precast block, be respectively equipped with the grout hole 4 being communicated with space, be provided with weather strip 5 at the two ends in space, reperfusion serosity in space.
This prefabricated assembly structural tongue-and-groove grouting formula joint mainly comprises tongue-and-groove 1, tenon 2 and grout hole 4., after slurries solidify, member tongue-and-groove is effectively connected with tenon, and can transmits concrete interlock shearing the space reperfusion serosity between tongue-and-groove and tenon by reserved grout hole 4, ensure that the dislocation distortion at tongue-and-groove and tenon interface is little.
Prefabrication and assembly construction component connector interface can be single tenon, double tenon or many tenons form, and height, width and the tapering (side slope angle) of tenon, tongue-and-groove requires to determine according to actual loading and assembling process.
Gap length between tongue-and-groove, tenon is comprehensively determined according to construction process requirement, slurry characteristics etc.;
Grouting pressure is comprehensively determined according to tongue-and-groove length, slurry characteristics and total grouting amount;
Arrangement and the material of grout hole arrange in member according to engineering demand.
By reference to the accompanying drawings 1, detailed description of the invention of the present utility model is explained as follows:
(1), according to the stressed and assembling process requirement of assembled joint, determine rational width, height and the tapering of tongue-and-groove 1, tenon 2;
(2) according to assembled joint profile height, determining joint quantity, can be single tenon, double tenon or many tenons;
(3), according to component assembly technological requirement, determine the height in the space 3 between tongue-and-groove 1 and tenon 2; Interspace in advance 3 unsuitable excessive, easily weaken the ability of joint Shear transfer;
(4) select space 3 grouting agents, ensure the intensity of grouting agent own and with concrete associativity;
(5) grouting agent is injected to the space 3 between tongue-and-groove 1 and tenon 2 by grout hole 4.
The above is preferred embodiment of the present utility model and the know-why used thereof; for a person skilled in the art; in the situation that not deviating from spirit and scope of the present utility model; any apparent change such as equivalent transformation, simple replacement based on technical solutions of the utility model basis, within all belonging to the utility model protection domain.
