Description of the invention: [Technical field to which the invention pertains] The present invention relates to a waterproof and shear-resistant expansion joint structure and a construction method for connecting old and new concrete structures, in particular to a joint of new and old concrete structures and providing waterproof and shear resistance. The effect of the expansion joint structure and construction method. [Prior Art] Old concrete structures are placed on the site. The site is subjected to the weight of old concrete structures and produces i τ traps. 'With the increase of time, the site will continue to sink. It will tend to be moderate and stable. Therefore, the site is loaded with old concrete. The contact block of the building will sink closer to the adjacent block that is not loaded with concrete. Among them, in the lap joint construction of the bridge, the construction of the house, the new and old retaining walls, and the approach roadway of the underground driveway of the building, when the new concrete building needs to be built on the periphery of the old concrete building, the weight of the new concrete building will cause the subsidence of the site. 'Because the site block below the new concrete building is unstable compared to the site below the old concrete building' and the new concrete building site block is in the process of subsidence, the combination of "- * _ 地地μμ曰Involving the concrete slabs where the concrete structures are sold, so that the contact surface of the new and old concrete buildings = the relative up-and-down displacement between the concrete structures and the formation of 曰U, 'bleaking, poor water resistance, so new The shear force of the old object on the connection A k This is the result of the h-shaped shear force and the poor water resistance of the 嶙, which is the heart of the problem. [Summary of the Invention] The main object of the present invention is to provide a waterproof and shear-resistant expansion joint structure and construction method of the new = civil construction connection is cloud, and the design is changed, and the cover is changed to 201137207. The waterproof property is not good. The building and a set of side in the old mixed construction, and the formation of the caulking layer in the groove of the object, the symmetrical setting of the old concrete, the shearing force of the new and old concrete building on the joint problem. The waterproof and anti-male expansion joint structure designed and manufactured according to the present invention is disposed between the old mixed concrete building and comprises: 至少 at least one shearing unit, the anti-strike The shearing unit comprises a shearing bar on the concrete building, and a pouring into the new concrete pipe, the casing provides the shearing bar to extend; at least the waterproofing unit is provided in one of the shearing units a water belt, one end of which is disposed between the old concrete building water γ and the old concrete building, and the other end of the waterstop is inserted into the new concrete building and is used for the old concrete building. # L-shaped stainless steel sheet clamps the water stop belt of the fixed extension to increase the water stop belt in the old concrete building; and - the buffer layer, which is set between the old concrete building and the new concrete building 0 == 揭目# ' The construction method of the water-resistant anti-shear expansion joint structure of the new and old concrete building designed by the Sun and the Moon includes: Ditching operation, which is fresh before the interface of the old concrete building. Civil construction "[Stainless steel" expansion Screw ^ old coagulation = force: solid Fix the water belt and increase the water stop belt in the old concrete building * - ', and the water stop belt is cast at the other end in the new concrete construction 丨 Shearing operation 'Shear rod of the shear unit - end implanted old concrete building S} 4 In 201137207, the corresponding casing is inserted into the male shackles of 靳, 曰, Sheng ^; and the U civil construction' provides a filling operation to fill a buffer layer between the old concrete building and the new concrete. According to the above, the new and old concrete building expansion joint structure and the construction side & +, waterproof and shear resistance of the present invention, the sale of concrete structures, and the corresponding casing are located in the new concrete building new Outside the rod concrete building, and the shear rod can be lived in the casing: this =: under the expansion joint 'other waterproof unit stop water belt: span = fully waterproof, and L-shaped stainless steel sheet clamping: The pull-out force of the water stop belt ensures the water stop: π掸 waterproof function. Therefore, the waterproof and shear-resistant expansion joint structure and construction method of the new and old concrete building of the present invention make the expansion joint of the new and old concrete building balance The design has excellent water resistance and shear resistance, reducing the adverse effects of site subsidence caused by new concrete structures on old concrete structures, and improving the stability of structural joints. [Embodiment] Referring to Figures 1 to 2, a preferred embodiment of the waterproof and shear-resistant expansion joint structure of the old and new concrete structures of the present invention is provided on the old concrete building (40) and the new concrete building ( Between 5)), it comprises at least one anti-shear unit (10), at least one waterproof unit (2〇) and a buffer layer (3〇). The shearing unit (10) comprises a shearing rod (11) and a hollow sleeve s (12), and the shearing rod (〗) is implanted into the old concrete building (4〇) ^, The end extends into the corresponding casing (12), and the casing (12) is poured into the new concrete structure (50), and the inner wall surface of the casing (〗 2) can be coated with butter to form a lubricating oil layer. The shear bar (11) can be used as a telescopic buffer in the corresponding casing (12) under shear and temperature changes. The waterproof unit (20) is disposed at the junction of the new and old concrete structures and is located on one side of the shearing unit (10), and the waterproof unit (20) includes a waterstop (21). One end of the water stop belt (21) extends into the groove (41) of the old concrete structure (40), and an adhesive is filled between the water stop belt (21) and the old concrete structure (40) to form a caulking layer, and Fix the water stop belt (21) to the old concrete structure. The other end of the water stop belt (21) is extended by pouring into the new concrete building (50), and the old concrete building (40) is placed on the old concrete building (40). A symmetrical L-shaped stainless steel piece (23), the L-shaped stainless steel piece (23) forms a fixing section (231) and a clamping section (232), and the fixing section (231) is locked by an expansion screw (24) On the old concrete building (4〇), the clamping section (232) of the two symmetrical l-shaped stainless steel sheets (23) is oppositely held by the water stop belt (21) of the old concrete building (40), and the plurality of locks are utilized. The firmware (25) locks the clamping section (232) with the waterstop (21), the fastener (25) comprising a bolt (26) and a nut (27), and the adjacent fastener (25) ) The bolts (26) and the nut (27) are locked in a staggered manner (as shown in the second figure). In the preferred embodiment of the present invention, the waterstop (21) may be a lithographic type. Water stop belt (21). The buffer layer (30) is disposed between the old concrete structure (4〇) and the new concrete building (50), wherein the buffer layer (3〇) may be a layered layer of expanded polystyrene sheets member.
