Description
Technical Field
The invention relates to a split connecting rod piece, in particular to a split connecting rod piece for a wall formwork with an integrated reinforcing steel bar formwork, and belongs to the technical field of building application.
Background
The prefabricated concrete technology is a technology for casting, curing and forming concrete components in factories and then designing and building a concrete structure house building in a field assembly mode. Compared with the traditional cast-in-situ building, the fabricated building has the advantages of high industrialization degree, easy guarantee of construction quality, short construction period, high economic benefit, little influence by climate and the like, and has no problems of water consumption, energy consumption, material waste, large waste emission and the like caused by site construction. Fabricated constructions have been strongly supported in recent years by national policies for their unique advantages.
In the existing production process of precast concrete members, the template is generally removed after pouring is completed, and the link not only increases labor cost, but also causes material waste. With the technical progress, can use the integrated template of pouring of exempting from to dismantle to replace traditional template, build the template shaping after, fix the template with the connecting rod spare, pour and maintain to meeting the requirements, template, wall body and the connecting rod spare of pre-buried in concrete become a whole promptly at this moment, need not demolish. The technical scheme reduces the construction flow, lowers the cost, avoids material waste, and meets the national energy conservation and emission reduction requirements. On the other hand, the disassembly-free integrated pouring template has great limitation in use: the fixed templates are generally connected by adopting connecting rods, the connecting method has high strength and strong integrity, but the conventional connecting rods are generally made of metal materials, the heat transfer coefficient of the conventional connecting rods is obviously higher than that of other parts, and the problem of serious thermal bridge effect is caused.
The heat bridge, also called cold bridge, generally refers to abnormal heat transfer parts with larger heat conductivity coefficient in building enclosures such as roofs, outer walls and the like. The thermal bridge effect is a thermal conduction physical effect, and because materials with relatively large heat conductivity coefficients are arranged in the parts, the thermal conduction capacity is strong, when the indoor and outdoor temperature difference is large, the heat conduction of the wall body is uneven, and heat flow is very dense at the thermal bridge part, so that a heat flow bridge is formed, namely a thermal bridge area. Since the thermal conductivity of conventional connecting rods is much greater than that of surrounding walls, the connecting rod portions are severely "hot bridge areas", which can lead to a series of serious problems: the heat loss is serious, and the wall surface temperature of the wall body has large variation range; condensation, frost heaving and freeze thawing phenomena are easily formed on the wall body in cold areas due to dew condensation on the surface of the wall body. These problems not only reduce the thermal performance of the wall and cause energy waste, but also reduce the service life of the wall and influence the indoor thermal stability.
And a butt-pulling connecting rod piece is arranged between the templates at two sides on the reinforced bar template integrated wallboard. The opposite-pull connecting rod piece not only bears the weight of the formwork, but also bears the lateral pressure of concrete during concrete pouring, so that the formwork is prevented from being damaged or expanded, and an important effect is played in the wall body. The opposite-pull connecting rod piece is connected with the templates at two sides of the wall body, and the whole wall body (including the heat insulation layer in the wall) needs to be penetrated, so that a serious thermal bridge phenomenon can be generated. If the connecting rod piece part meets the corresponding mechanical requirement and can keep good thermal performance, the opposite-pull connecting rod piece needs to be subjected to heat-insulating bridge treatment, so that the opposite-pull connecting rod piece of the bridge-cut-off type steel bar formwork integrated wall formwork is provided for solving the problems.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1-4, a bar template integrated wall template bridge-cutoff opposite-pull connection rod piece is characterized in that: the bridge-cut-off connecting piece comprises four parts, namely a bridge-cut-off connecting piece 1, a first metal screw rod 2, a second metal screw rod 3 and a gasket 4; the center line of the cylinder of the broken bridge connecting piece 1 is provided with a connecting groove, the first metal screw rod 2 and the second metal screw rod 3 are respectively arranged at two ends of the broken bridge connecting piece 1, the first metal screw rod 2 and the second metal screw rod 3 are respectively connected with the broken bridge connecting piece 1, and a gap at the connecting part is filled with structural adhesive 5;
wherein the first metal screw 2 and the second metal screw 3 comprise a threaded end and a screw cap; the washers 4 are placed outside the first metal screw nut 6 and the second metal screw nut 7, respectively.
As a technical optimization scheme of the invention, the second metal screw 3 is a hollow metal screw, and the hollow cavity is communicated with the hollow cavity in the bridge-cutoff connecting piece 1 to form a hollow slurry guiding and measuring cavity 9; the flexible sampling probe 10 is inserted into the hollow slurry guiding and measuring cavity 9, a plurality of sampling grooves 11 are formed in the head of the flexible sampling probe 10, and the non-packaging RFID anti-metal chip 12 is bonded on the bridge-cutoff connecting piece 1.
As a technical optimization scheme of the invention, the broken bridge connecting piece 1 adopts engineering plastics or other materials with low heat conductivity coefficient, and on the basis of guaranteeing the use function of the connecting rod piece, the heat bridge effect is greatly reduced due to the adoption of the engineering plastics in the middle section.
As a technical optimization scheme of the invention, the hollow slurry guiding and measuring cavity 9 is provided with a horn mouth which is opened downwards at the opening of the surface of the bridge-cutoff connecting piece 1.
As a technical optimization scheme of the invention, the flexible sampling probe 10 is a strip-shaped probe which can be bent and deformed, and the scale is arranged on the strip-shaped probe.
As a technical optimization scheme of the invention, the broken bridge connecting piece 1 is in threaded connection with the metal screw rod, has a good anti-corrosion function, ensures firm and durable connection between the broken bridge connecting piece 1 and the metal screw rod, and can be used for a long time in various environments.
As a technical optimization scheme of the invention, an air layer 8 is arranged between the first metal screw rod 2 and the bridge-cut-off connecting piece 1, engineering glue is smeared on the threaded end of the metal wire, and the air layer 8 reserved between the heat insulation block and the metal screw rod has good heat insulation effect; and engineering glue is smeared at the threaded end of the metal lead screw, the air tightness and the like of the connection between the connecting rod and the bridge-cut-off connecting piece 1 are increased, and the measures can cut off a heat flow path and improve the heat resistance of a heat bridge part, so that the problem of a heat bridge effect is effectively solved.
When the invention is used, the connecting rod pieces are symmetrically arranged, the middle is a bridge-cut-off connecting piece, and the two sides are metal screw rods. The cavity of the second metal screw 3 is communicated with the cavity in the bridge-cut-off connecting piece to form a hollow slurry guiding and measuring cavity, and when the wall body is concreted, concrete can be reserved outside the template from the inside of the wall body through the hollow slurry guiding and measuring cavity 9. The hollow slurry guiding and measuring cavity 9 is provided with a horn mouth which is opened downwards at the opening of the surface of the bridge-cut-off connecting piece 1, so that concrete is easy to enter. The downward opening ensures that the concrete enters under the action of pressure rather than gravity, and can truly reflect the compactness of the concrete around the bridge-cut-off connecting piece 1. After the building is built, a temperature sensor such as a thermocouple can be inserted into the broken bridge connector 1 through the hollow slurry guiding and measuring cavity 9, so that the thermal performance of the wall body can be studied. The flexible sampling probe 10 is a strip-shaped probe which can be bent and deformed, and is provided with scales, and can be inserted into the hollow slurry guiding and measuring cavity 9 to probe the condition of the concrete entering the hollow slurry guiding and measuring cavity. The head of the flexible sampling probe 10 is provided with a plurality of sampling grooves 11, so that the flexibility of the head of the flexible sampling probe can be increased, whether concrete enters the hollow slurry guiding and measuring cavity 9 or not can be judged according to the insertion depth of the probe and the condition of the concrete extracted from the grooves, and whether the concrete around the bridge-cutoff connecting piece 1 is poured compactly or not is judged. The invention provides an unpackaged RFID anti-metal chip 12 (which is bonded to the broken bridge connector 1) which is damaged after water or concrete immersion and cannot emit a signal. Using RFID anti-metal chip 12 reading equipment outside the wall panel, it can be checked whether the chip is damaged. If the chip is damaged, this indicates that the concrete has submerged the chip. If the chip is not damaged and can be read by the reading equipment of the RFID anti-metal chip 12, the chip is not immersed by the concrete, and a cavity with uncompacted concrete exists at the periphery of the bridge-cutoff connector 1. The non-encapsulated RFID anti-metal chip 12 is utilized to check concrete cavity conditions, although a probe is not needed, the method is relatively convenient, in order to prevent water flowing on an attached wall surface from entering a cavity horn mouth to submerge the chip, the non-encapsulated RFID anti-metal chip 12 cannot be installed at the horn mouth and is a certain distance away from the surface of the bridge-cut-off connecting piece 1, so that the two methods of probing the flexible sampling probe 10 and sensing the non-encapsulated RFID anti-metal chip 12 are combined, and the condition that concrete around the bridge-cut-off connecting piece 1 is compact can be more accurately indicated. When the compactness of the concrete needs to be checked quickly, the induction method of the non-packaged RFID anti-metal chip 12 is practical, and the flexible sampling probe 10 can be used for detection and repeated detection. When it is not necessary to check the concrete compactness quickly, the unpackaged RFID anti-metal chip 12 may not be provided and only the flexible sampling probe 10 is used to probe when the concrete is not set.
